Published: June 2024

Breast implant rupture is one of the most common complications in aesthetic and reconstructive surgery. Furthermore, this problem is closely linked to capsular contracture. It is therefore crucially important to effectively and promptly remove silicone leakage from breast pockets. Several techniques are described in the literature and have been typically used for this procedure. Hydrosurgical debridement (HD), which is usually applied in wound care to treat wounds, could be useful for the removal of the silicone leaked from prosthesis pockets after breast implant rupture. An entire periprosthetic capsule that contained a ruptured implant with silicone leakage was removed from a left breast. Half of the capsule was treated with HD, whereas the other half was left untreated as a control. Samples were processed by light microscopy and scanning electron microscopy for morphological analyses. light microscopy demonstrated that the nontreated tissues had a typical synovial-like structure with a middle layer of connective tissue in which there were numerous rounded empty spaces which contained silicone. In contrast, the superficial connective region of the treated tissues (T) had fewer and flattened spaces where the silicone was detected. Scanning electron microscopic analysis showed that in the T samples, the capsule thickness was compact compared with that of the nontreated tissues. Furthermore, the fibrous components appeared well organized with few and smaller silicone lacunae. HD is useful for the removal of silicone (ex vivo) from capsular surfaces after implant rupture. Because of its safety characteristics, this technique could be successfully used in vivo.

Authors: Albrecht Jennifer S. , Gardner Raquel C. , Bahorik Amber L. , Xia Feng , Yaffe Kristine
Published: June 2024

Objective:

To estimate the impact of traumatic brain injury (TBI) on prevalence of posttraumatic stress disorder (PTSD), depression, and alcohol and substance use disorders.

Setting:

A random sample of Veteran’s Health Administration data.

Participants:

A total of 14 116 veterans aged ≥55 with incident late-life TBI between October 1, 1999, and September 31, 2021, were matched 1:3 on age and TBI date to 42 678 veterans without TBI.

Design:

Retrospective cohort study.

Main Measures:

PTSD, depression, and alcohol and substance use disorders were identified using diagnostic codes. Participants were censored after the first diagnosis during the year before and the year after the TBI or matched date. Prevalence rates of PTSD, depression, alcohol, and substance use disorders were compared before and after incident TBI or matched date using Poisson regression.

Results:

Pre-TBI prevalence rates of disorders were higher among those with TBI relative to those without TBI. Pre-TBI PTSD prevalence rates (per 1000 person-years) were 126.3 (95% CI, 120.2-132.4) compared to 21.5 (95% CI, 20.1-22.9) in the non-TBI cohort. In adjusted models, TBI was not associated with an increase in the prevalence of any of the studied disorders.

Conclusions:

Prevalence rates of depression, PTSD, and alcohol and substance use disorders were 5 to 10 times higher among older veterans before incident TBI. We did not observe an increase in the prevalence of these disorders after incident TBI. Older veterans with these disorders may be at increased risk for TBI.
Evaluation and Pharmacologic Management of Paroxysmal Sympathetic Hyperactivity in Traumatic Brain Injury
Authors: Ott Jamie L. , Watanabe Thomas K.
Published: June 2024

Objective:

Paroxysmal sympathetic hyperactivity (PSH) can occur in up to 10% of severe traumatic brain injury (TBI) patients and is associated with poorer outcomes. A consensus regarding management is lacking. We provide a practical guide on the multi-faceted clinical management of PSH, including pharmacological, procedural and non-pharmacological interventions. In addition to utilizing a standardized assessment tool, the use of medications to manage sympathetic and musculoskeletal manifestations (including pain) is highlighted. Recent studies investigating new approaches to clinical management are included in this review of pharmacologic treatment options.

Conclusion:

While studies regarding pharmacologic selection for PSH are limited, this paper suggests a clinical approach to interventions based on predominant symptom presentation (sympathetic hyperactivity, pain and/or muscle hypertonicity) and relevant medication side effects.
CLINICOPATHOLOGIC CHANGES OF VITREOMACULAR INTERFACE IN IDIOPATHIC EPIRETINAL MEMBRANE WITH DISORGANIZATION OF RETINAL INNER LAYERS
Authors: Li Huanhuan , Liu Yan , Yao Jinghong , Zheng Jiusheng , Yang Yanting , Li Hui , Wang Fang , Liu Yao
Published: June 2024

Purpose:

To compare the pathological characteristics of the vitreomacular interface of the idiopathic epiretinal membrane with and without disorganization of retinal inner layers (DRIL) and to correlate with clinical data.

Methods:

In this clinicopathologic study, the samples of epiretinal membrane and internal limiting membrane were extracted from DRIL(+) (19 eyes) and DRIL(−) (22 eyes) idiopathic epiretinal membrane eyes. Ultrathin series sectioning for transmission electron microscopy was observed and correlated with surgery status and prognosis.

Results:

All idiopathic epiretinal membrane eyes presented fibrocellular membranes accompanied by vitreous collagen, glial cells, and myofibroblasts, regardless of association with DRIL. A robust signal indicative of Collagen Type VI was observed in eyes DRIL(−), whereas Collagen Type I was discovered in DRIL eyes. Cell debris and microvascular basement membrane were seen on the retinal side of DRIL eyes and a larger cell count on the vitreous side. These have more intraoperative complications and less surgery benefit.

Conclusion:

Although internal limiting membrane peeling seems important, the histopathologic findings underscore the potential for retinal injury in DRIL(+) idiopathic epiretinal membrane eyes. This suggests that further research is needed to investigate individual preoperative assessment and to modify surgical procedures.
Exogenous testosterone use and acute central serous chorioretinopathy in a transgender patient
Authors: Fowler Benjamin J , Schildroth Kathleen R
Published: June 2024

Purpose:

To describe the presentation and clinical course of a transgender patient with central serous chorioretinopathy (CSCR) and discuss the role of exogenous testosterone use in CSCR in this patient population.

Method:

Case report.

Results:

A 63-year-old transgender male with a history of exogenous testosterone use for over twenty years was referred to retina clinic for evaluation of macular pathology. The patient’s most recent total testosterone levels prior to presentation were 962 and 1,179 ng/dL (normal cisgender male levels for age 60+: 300-720 ng/dL). Fundus imaging revealed subretinal fluid involving the fovea without choroidal neovascularization in the right eye. There was no recent corticosteroid use. The patient’s dose of testosterone was reduced. After four months of observation, the subretinal fluid persisted and was successfully treated with half-fluence photodynamic therapy (PDT). At last follow-up, 15 months after PDT, the patient remained stable without recurrence and the best-corrected visual acuity was at baseline.

Conclusion:

Exogenous testosterone use with elevated serum testosterone levels may be associated with the development of central serous chorioretinopathy in the transgender patient population. CSCR in these patients might be effectively treated with PDT and testosterone dose reduction. Ophthalmologists should be aware of potential side effects of testosterone supplementation in this patient population, as well as the role of testosterone in CSCR pathophysiology.

Authors: Smith Karli , Smith Hayden L. , Wittry Alex , Conley Gabriel , Leech Jodi , Kluesner Nicholas
Published: June 2024

BACKGROUND:

Hospital quality-assurance (QA) processes, including peer-review committees, seek to identify high-risk areas.

PURPOSE:

To characterize emergency department (ED) cases sent for QA review.

METHODS:

A retrospective observational study was conducted of ED cases sent to a QA committee from November 2018 through July 2022 at three midwestern US hospitals. The QA records analyzed for these cases included the original incident report, case summary, and the committee determinations.

RESULTS:

One hundred and forty-seven cases were reviewed by the ED QA Committee. The most frequent referrals came from physicians. Common diagnostic categories included infectious (21%), cardiac (16%), gastrointestinal (11%), and neurologic (10%) concerns. Of the cases, 51% were considered nonpreventable, 33% were potentially preventable, and 9% were preventable. Inpatient boarding in the ED was explicitly implicated as a contributing factor in 6% of case reports.

CONCLUSIONS:

Peer physician reporting represent the largest referral source sent for review with the most frequent diagnostic categories, including infectious, cardiac, gastrointestinal, and neurological conditions. Preventable concerns were rare.

IMPLICATIONS:

This study provides a better understanding of the referral sources, diagnostic categories, and committee determinations in ED quality concerns. These results can target future investigations into case reporting and patient safety.
A System Intervention to Increase Pneumococcal Vaccination Rates in Adults Living With Human Immunodeficiency Virus Who Present for Scheduled Medical Care
Authors: Jensen Jodene , Waldrop Julee , Derouin Anne , Siegel Amber
Published: June 2024

Pneumococcal vaccinations are recommended for adults living with HIV; however, eligibility criteria are complex. At a clinic specializing in the care of lesbian, gay, bisexual, transgender, or queer/questioning persons, only 36% of patients who were vaccine-eligible received the vaccination. A set of decision trees was developed to guide clinic personnel in determining whether a vaccine is recommended. The provider then determined whether the vaccine was appropriate based on each patient's complete clinical presentation. When appropriate, patients were offered the vaccine at the same appointment. This practice change led to a 22% increased vaccination rate.

Published: June 2024

There is a shortage of health-related questionnaires developed specifically for African countries' cultural contexts and local languages. Researchers have translated some tools to the target local languages. However, poor-quality or even high-quality translation can lead to an instrument that is not comparable with the original language if linguistic nuances, and cultural differences are not considered. This can affect the validity and reliability of the research data. The objective of this commentary was to highlight limitations of the commonly accepted forward–backward translation approach and the importance of more rigorous cultural and linguistic adaptation processes in social and behavioral research related to HIV.
Unlocking HIV Prevention in Primary Care: Implementation of the Denver HIV Risk Score Tool in an Urban Michigan Primary Care Setting
Authors: Knight Jay Julienne
Published: June 2024

The Unlocking HIV Prevention Project was designed and implemented to address missed opportunities to address HIV risks. The project's site noted a gap in the use of an HIV risk assessment tool during primary care visits. The purpose of this quality-improvement project was to determine whether the translation of the Denver HIV Risk Score tool into primary care visits would affect the number of individuals identified as at risk for HIV and increase preexposure prophylaxis (PrEP) prescription rates among adults seeking care at an urban Michigan primary care clinic. Data on PrEP prescriptions were collected from the electronic health record before and after implementation of the HIV risk assessment tool. Before implementing this screening tool, no patients were identified as at risk and no prescriptions for PrEP were written. After implementation, 16 patients were identified as at risk with seven prescriptions written. These data suggest that this tool has the potential to improve the identification of patients at risk for HIV who are candidates for PrEP prescribing in primary care.
Association Between Pupil Light Reflex and Delirium in Adults With Traumatic Brain Injury: Preliminary Findings
Authors: Lapierre Alexandra , Proulx Annie , Gélinas Céline , Dollé Stéphanie , Alexander Sheila , Williamson David , Bernard Francis , Arbour Caroline
Published: June 2024

BACKGROUND:Delirium is a common neurological complication in patients admitted to the intensive care unit (ICU) after moderate to severe traumatic brain injury (TBI). Although current clinical guidelines prioritize delirium prevention, no specific tool is tailored to detect early signs of delirium in TBI patients. This preliminary 2-phase observational study investigated the correlation between the pupillary light reflex (PLR), measured with a pupillometer during mechanical ventilation, and the development of postextubation delirium in TBI patients.METHODS:A convenience sample of 26 adults with moderate to severe TBI under mechanical ventilation was recruited during their ICU stay. In phase I, PLR measurements were performed in the first 3 days of ICU admission using automated infrared pupillometry. In phase II, 2 raters independently extracted delirium data in the 72 hours post extubation period from medical records. Delirium was confirmed with a documented medical diagnosis. Point-biserial correlations (rpb) were used to examine the association between PLR scores and the presence of postextubation delirium. Studentttests were also performed to compare mean PLR scores between patients with and without delirium.RESULTS:Ten TBI patients (38%) were diagnosed with postextubation delirium, whereas 16 (62%) were not. Significant correlations between delirium and 2 PLR variables were found: pupil constriction percentage (rpb(24) = −0.526,P= .006) and constriction velocity (rpb(24) = −0.485,P= .012). Thettest also revealed a significant difference in constriction percentage and velocity scores between TBI patients with and without delirium (P≤ .01).CONCLUSION:Our findings suggest that the use of pupillometry in the first 3 days of mechanical ventilation during an ICU stay may help identify TBI patients at risk for delirium after extubation. Although further research is necessary to support its validity, this technological tool may enable ICU nurses to better screen TBI patients for delirium and prevent its development.
Creative Solutions for a Condensed Anatomy Course
Authors: DeVaul Nicole , Carroll Melissa A. , Brown Kirsten M.
Published: June 2024

There are many variations of anatomy courses taught in accredited physician assistant (PA) programs in the United States. Course directors and program leadership must choose how to effectively deliver content within their program constraints. Our anatomy course has faced challenges related to instructional time for didactic and laboratory sessions, course length, curricular placement and alignment, assessments, and faculty availability. These challenges are not specific to anatomy courses in PA curricula but exist in anatomy courses in various health care programs. In this article, we present major solutions to challenges in didactic delivery, laboratory sessions, course content, and assessments over a 5-year period. Through modifications and problem-solving, we identified the following 4 lessons learned during this process: course alignment to clinical relevance, intentional content delivery for different pedagogical approaches, structured laboratory sessions with appropriate staffing, and an appropriate weighting for assessments. These lessons and solutions will be useful to other anatomy and disciplines-based course directors facing similar challenges.

Published: June 2024

Background:

Gastric tube insertion is necessary to support early enteral feeding of newborns during their neonatal intensive care stay. This frequent and invasive procedure is known to be painful. Very few analgesic techniques (sweet solutions, sucking, swaddling, and skin-to-skin contact) are available to reduce the pain caused by orogastric tube insertion procedure. Objective: To determine whether a new orogastric tube insertion technique modifies the pain response in newborns, we hypothesize that inserting an orogastric tube through the nipple of a bottle reduces pain caused by this procedure.

Design:

Prospective, controlled, randomized, multicentered and open label study.

Setting(s):

Three neonatal intensive care units in France (2 level 3 units and 1 level 2B).

Participants:

Full-term or premature newborns at 32 weeks of gestation or more, postnatal age between 48 hours and 21 days, not ventilated and requiring enteral feeding, were randomized into 2 groups: usual technique (n = 36) and experimental technique (n = 35).

Methods:

Our experimental technique was to insert the orogastric tube through a modified nipple of a bottle. This method was compared with the usual technique of inserting the tube directly into the newborn's mouth without a support to guide it accompanied by a nipple encouraging sucking with a nonnutritive solution. An association of nonnutritive sucking and orally administered 30% glucose was given to all children for analgesic purposes. Pain during the orogastric tube insertion was assessed on video recordings by 2 independent experts, using a heteroassessment behavioral scale for pain (DAN—Douleur Aiguë du Nouveau-né; APN—Acute Pain in Newborns). The primary outcome was an Acute Pain in Newborns score of less than 3 at the time of the procedure. Comparisons were made using Fisher exact test or Mann-Whitney U test. Factors associated with an Acute Pain in Newborns score of 3 and greater were explored using univariable and multivariable regression models.

Results:

All but 1 video recording in each group were analyzed. Among the 34 neonates in the experimental group, 71.4% (95% CI: [53.7-85.4]) had an Acute Pain in Newborns score of less than 3 during orogastric tube insertion versus 41% (95% CI: [27.9-61.9]) in the control group (P = .031). Gagging was frequent and nonsignificantly different between the 2 groups (69% in the control group, 51% in the experimental group, P = .13). In multivariable analysis, the experimental technique was an independent factor of pain prevention compared with the usual technique (odds ratio = 0.21 [0.06-0.71], P = .015).

Conclusions:

This study suggests that a simple, inexpensive, and feasible technique of orogastric tube insertion through the nipple of a bottle limits pain associated with this procedure in newborns.
Multimodal imaging-based prediction of recurrence for unresectable HCC after downstage and resection-cohort study
Authors: Jiang Hanyu , Zuo Mengxuan , Li Wang , Zhuo Shuiqing , Wu Peihong , An Chao
Published: June 2024

Background:

Surgical resection (SR) following transarterial chemoembolization (TACE)-based downstaging is a promising treatment for unresectable hepatocellular carcinoma (uHCC), and identification of patients at high-risk of postoperative recurrence may assist individualized treatment.

Purpose:

To develop and externally validate preoperative and postoperative prognostic models integrating multimodal CT and digital subtraction angiography features as well as clinico-therapeutic-pathological features for predicting disease-free survival (DFS) after TACE-based downstaging therapy.

Materials and methods:

From March 2008 to August 2022, 488 consecutive patients with Barcelona Clinic Liver Cancer (BCLC) A/B uHCC receiving TACE-based downstaging therapy and subsequent SR were included from four tertiary-care hospitals. All CT and digital subtraction angiography images were independently evaluated by two blinded radiologists. In the derivation cohort (n=390), the XGBoost algorithm was used for feature selection, and Cox regression analysis for developing nomograms for DFS (time from downstaging to postoperative recurrence or death). In the external testing cohort (n=98), model performances were compared with five major staging systems.

Results:

The preoperative nomogram included over three tumors [hazard ratio (HR), 1.42; P=0.003], intratumoral artery (HR, 1.38; P=0.006), TACE combined with tyrosine kinase inhibitor (HR, 0.46; P<0.001) and objective response to downstaging therapy (HR, 1.60; P<0.001); while the postoperative nomogram included over three tumors (HR, 1.43; P=0.013), intratumoral artery (HR, 1.38; P=0.020), TACE combined with tyrosine kinase inhibitor (HR, 0.48; P<0.001), objective response to downstaging therapy (HR, 1.69; P<0.001) and microvascular invasion (HR, 2.20; P<0.001). The testing dataset C-indexes of the preoperative (0.651) and postoperative (0.687) nomograms were higher than all five staging systems (0.472–0.542; all P<0.001). Two prognostically distinct risk strata were identified according to these nomograms (all P<0.001).

Conclusion:

Based on 488 patients receiving TACE-based downstaging therapy and subsequent SR for BCLC A/B uHCCs, the authors developed and externally validated two nomograms for predicting DFS, with superior performances than five major staging systems and effective survival stratification.

Authors: Khan Dikhra , Phulia Ankita , Kumar Suraj , Sarswat Sulochana , KV Sivasankar , Sagar Sambit
Published: June 2024

Aim

This study aimed to evaluate the potential role of 18F-fluorodeoxyglucose PET/computed tomography (18F-FDG PET/CT) in providing a targeted approach for diagnosing the etiology of Pyrexia of Unknown Origin (PUO).

Methods

A total of 573 PUO patients were included in this ambispective study, with a mean age of 39.40 ± 4.6 years. Patients underwent FDG PET/CT scans using dedicated hybrid scanners. PET/CT data were interpreted by experienced nuclear medicine physicians. The study analyzed the guidance provided by FDG PET/CT for appropriate biopsy sites and assessed concordance between PET/CT findings and histopathological examination.

Results

Out of the 573 patients, a final diagnosis was reached for 219 patients, including malignancy, infectious causes, noninfectious inflammatory causes (NIID), and precancerous conditions. FDG PET/CT played a crucial role in guiding clinicians to appropriate biopsy sites, contributing to a higher diagnostic yield. Concordance between PET/CT findings and histopathological examination emphasized the noninvasive diagnostic potential of PET/CT in identifying underlying causes of PUO. Overall, FDG PET/CT contributed to guiding the appropriate site of biopsy or concordance of the first differential diagnosis with the final diagnosis in 50.05% of cases.

Conclusion

This study highlights the valuable role of FDG PET/CT in providing a targeted approach for diagnosing PUO, showcasing its potential in guiding clinicians towards appropriate biopsy sites and improving the diagnostic yield. The findings underscore the importance of integrating FDG PET/CT into the diagnostic pathway for PUO, ultimately enhancing patient management and outcomes. Further prospective studies are necessary to validate these results and refine the integration of FDG PET/CT in the diagnosis of PUO.

Authors: Algodayan Sarah , Balachandar Ramya , Papathanasiou Nikolaos , Bomanji Jamshed , Porter John B. , Waung Julian
Published: June 2024

Objectives

In this study, we aim to evaluate the long-term impact of thalassaemia on bone mineral density (BMD) through sequential analysis, compare changes in BMD values between male and female patients and find any correlation between BMD and biochemical markers in the adult thalassaemia group. BMD is a bone mineral density test using dual-energy X-ray to measure calcium hydroxyapatite per unit of bone, reflecting bone strength.

Methods

We conducted a longitudinal retrospective observational cohort study to determine the changes in BMD values and biochemical parameters in adult thalassaemia patients. BMD was assessed at the lumbar spine (L1–L4) and proximal femora using Hologic’s bone dual-energy X-ray absorptiometry. Five serial BMD values were retrieved from electronic records. Biochemical parameters, including serum calcium, phosphorus and 25-hydroxyvitamin D levels, were also assessed.

Results

A total of 108 patients (47 males and 61 females; median age: 44 years) with thalassaemia major 71 patients, intermedia 20 patients, haemoglobin E disease 14 patients and thalassaemia-alpha three patients were included. The incidence of low BMD in patients with thalassaemia increased from 64 to 74% over three decades of analysis. Females and thalassaemia major patients had lower hip BMD values and corresponding Z-scores.

Conclusion

There is a progressive decline in BMD values in adult thalassaemia, which was apparent in female thalassaemia major patients. No changes in biochemical parameters, however, were observed over long-term assessments.
Analysis of delayed initial radioactive iodine therapy and clinical outcomes in papillary thyroid cancer: a two-center retrospective study
Authors: He Tao , Li Ming , Gao Zheng-lian , Li Xiang-yu , Zhong Hai-rong , Ding Cui-shuang , Cai Hua-wei
Published: June 2024

Background

It remains unclear whether the time interval between total thyroidectomy and radioactive iodine (RAI) therapy influences clinical outcomes in papillary thyroid carcinoma (PTC). This study aims to evaluate the impact of the timing to initiate RAI therapy on the response in PTC patients.

Methods

We retrospectively included 405 patients who underwent total thyroidectomy and subsequent RAI therapy at two tertiary hospitals in southwest China. Patients were categorized into two groups based on the interval between thyroidectomy and initial RAI therapy, that is, an early group (interval ≤90 days, n = 317) and a delayed group (interval >90 days, n = 88). Responses to RAI therapy were classified as excellent, indeterminate, biochemical incomplete, or structural incomplete. Univariate and multivariate analyses were conducted to identify factors associated with a nonexcellent response.

Results

Excellent responses were observed in 77.3% of the early group and 83.0% of the delayed group (P = 0.252). No significant impact of RAI therapy timing was also observed across all American Thyroid Association risk classification categories. These findings persisted when patients were analyzed separately according to RAI dose (intermediate-dose group: 3.7 GBq [n = 332]; high-activity group: ≥5.5 GBq [n = 73]), further subdivided by the timing of RAI therapy. Multivariate analysis identified lymph node dissection, RAI dose, and stimulated thyroglobulin as independent risk factors for excellent response (P < 0.05).

Conclusion

The timing of initial RAI therapy following surgery did not significantly affect outcomes in patients with PTC.
The increase in diabetes in children from underdeveloped countries
Authors: Zhang Cai , Luo Xiaoping
Published: June 2024

Purpose of review

The incidence of type 1 diabetes (T1D) in children and adolescents has been increased over decades worldwide. Recent studies showed that the trend of T1D incidences were different between developed and underdeveloped countries. This review aimed to summarize the changes of childhood T1D incidences in underdeveloped countries over the past decade.

Recent findings

Majority of the underdeveloped countries lacked of nationwide population-based studies on childhood T1D. We reviewed the trend of childhood T1D in important underdeveloped countries with available data in recent years. The incidences of childhood T1D in underdeveloped countries were low decades ago, but it increased significantly recently, particularly in the sub-Saharan African, Middle East and North African regions.

The incidences of childhood T1D increased significantly in underdeveloped countries, especially in the sub-Saharan African, Middle East and North African regions. T1D registry and population-based studies are helpful to understand the situation and characteristic of childhood T1D in underdeveloped countries.

Authors: Chalard François , Nguyen Toan , Morel Baptiste , Leiber Louis-Marie , Roux Charles-Joris , Petit Philippe , Soto Ares Gustavo , Donadieu Jean , Ducou le Pointe Hubert
Published: June 2024

Background:

Juvenile Xanthogranuloma (JXG) is a non-Langerhans cell histiocytosis, occurring mainly in infancy. With an extracutaneous lesion, its diagnosis is difficult, because of a wide clinical spectrum. Here we demonstrate and characterize imaging features of 11 patients with JXG of the head and neck in various locations.

Material and Methods:

We recorded clinical data and reviewed all imaging studies of 11 patients with JXG of the head and neck. Ultrasonography (US) alone was performed in 1 patient; MRI alone in 6 patients; US and MRI in 1 patient; and US, CT, and MRI in 3 patients. We evaluated the following characteristics in all studies: location and number of lesions, echogenicity and vascularization on US, density on CT, signal intensity on T1- and T2-weighted images, ADC and enhancement on MRI, and tumor boundaries and bone involvement.

Results:

Lesions were well-defined in 9 cases, and bone erosion was present in 2. On US, lesions were hypoechoic or hyperechoic and with or without vascularization. On CT, lesions were hyper-dense, with no calcification. On MRI, lesions were mildly hyper-intense or iso-intense on T1-weighted images in 8 of 9 patients, hypo-intense on T2-weighted images in 7 of 10, low ADC in 7 of 9, and enhancement in 7 of 7.

Conclusions:

The diagnosis of extra cutaneous JXG may be proposed, with the following suggestive criteria: age < 1 year, well-defined lesion, mild hyper-intensity on T1-weighted images, hypo-intensity on T2-weighted images, low ADC, enhancement, and possible adjacent bone involvement.

Published: June 2024

Human herpesvirus 6 (HHV-6) is a widely spread DNA virus that is ubiquitous and persistent with primary infection occurring in early childhood, with reactivation of the infection a common phenomenon in severely immunocompromised hosts, including hematopoietic stem cell transplant (HSCT) patients, influencing morbidity and mortality. A wide spectrum of clinical presentations is reported in the literature with HHV-6 reactivation including post-transplant limbic encephalitis (PALE). We report the unusual case of a 6-year-old female 107 days postallogenic HSCT due to transfusion dependent beta thalassemia major who developed acute cerebellitis with secondary supratentorial hydrocephalus that required invasive surgical intervention. In addition to accompanying imaging findings, the patient tested positive for HHV-6 by PCR from both serum and CSF samples and demonstrated dramatic improvement with the institution of steroid therapy in addition to ganciclovir treatment. The availability of rapid diagnostic measures in addition to a multidisciplinary approach is crucial to manage HHV-6 encephalitis and associated complications in HSCT patients.
Comparison of Yearly Cost Related to Complications Between Deferasirox and Deferiprone Monotherapy in Thalassemia
Authors: Sari Teny Tjitra , Wahidiyat Pustika Amalia , Rahmartani Ludi Dhyani , Iskandar Stephen Diah , Putri Isyanaditta Agung
Published: June 2024

Background:

Hemoglobin disorders such as thalassemia major have created an economic burden on the health care system. Iron chelation therapy (ICT) is the most expensive cost component in patients with thalassemia. ICT was administered to reduce the toxic effects of iron overload. This study aims to compare the costs of iron chelators as monotherapy in patients with thalassemia major in Indonesia, specifically in Cipto Faculty of Medicine, Universit.

Methods:

This is a retrospective analytical observational study. Data were collected from the thalassemia registry from 2016 to 2019. Patients’ age, gender, type of thalassemia, and type of iron chelation were recorded. Complications and total annual costs were evaluated. All thalassemia patients aged ≥2 years who were only receiving monotherapy ICT and had no history of therapy switching were eligible. We excluded subjects who moved out to other facilities or lost to follow-up.

Results:

From a total of 256 subjects, 249 subjects were included. The median age is 28 years old. Both sexes were represented equally. As many as 96.8% of subjects have thalassemia beta. Deferiprone was the most common iron chelator used (86.7%). Complications were observed in the subjects based on 4-year data collection; most of them were cardiomyopathy, diabetes mellitus, delayed puberty, and malnutrition (P=0.422; P=0.867; P=0.004; and P=0.125, respectively). Deferiprone had a lower mean annual cost of USD 3581 than deferasirox, which had a cost of USD 6004.

Conclusions:

Cardiomyopathy, diabetes mellitus, delayed puberty, and malnutrition were the most common complications found in the study. This study showed that deferiprone should be taken as consideration as a drug of choice to treat iron overload in thalassemia provided by Indonesian national health insurance which is less costly despite the probability of complications found after the treatment was given. Further investigations are required to evaluate contributing factors of complications in thalassemia.

ECG changes in pneumothorax have gained recognition as important indicators of cardiopulmonary interactions. This narrative review examines the existing literature to provide insights into the various ECG abnormalities observed in patients with pneumothorax, their underlying mechanisms, and clinical implications. The review highlights the commonly reported changes, including alterations in the electrical axis, ST segment deviations, T-wave abnormalities, and arrhythmias. The rightward shift of the electrical axis is attributed to cardiac displacement caused by increased intrathoracic pressure. ST segment deviations may reflect the influence of altered intrathoracic pressure on myocardial oxygen supply and demand. T-wave abnormalities may result from altered myocardial repolarization and hypoxemia. Arrhythmias, although varying in incidence and type, have been associated with pneumothorax. The clinical implications of these ECG changes are discussed, emphasizing their role in diagnosis, risk stratification, treatment optimization, and prognostication. Additionally, future research directions are outlined, including prospective studies, mechanistic investigations, and the integration of artificial intelligence. Enhancing our understanding of ECG changes in pneumothorax can lead to improved patient care, better management strategies, and the development of evidence-based guidelines. The objective of this review is to demonstrate the presence of various ECG abnormalities in patients with pneumothorax.

Background:

Adopting a physically active lifestyle is advocated as a strategy to prevent loss of physical independence and support healthy aging. This study aimed to evaluate the physical independence and related factors among older adults.

Materials and methods:

This systematic review and meta-analysis was conducted through electronic databases such as Scopus, PubMed, Web of Science, Iranmedex, and Scientific Information Database from the earliest to 1 April 2022. Two researchers independently extracted information from the studies and evaluated the quality of the studies. The analysis was conducted using CMA program version 3, and each study’s importance was determined based on its inverse variance.

Results:

Five thousand seven hundred thirty-three older adults participated in this review in six studies. All evaluated studies had high quality. The mean score of physical independence in older adults was 20.07 (SE=0.76) out of 24 (95% CI: 18.58–21.56; I2
=98.573%; P<0.001). Physical activity is very important for physical independence and reduces the risk of physical dependence in older adults. Other factors, such as sex, BMI, age, abnormal performance, timed performance, sufficiently active, muscle function, handgrip strength, lower extremity function, lower body strength, maximal isometric knee extension power, lung function, aerobic endurance, sedentary time, agility, and the prevalence of arthritis, had a significant relationship with physical independence in older adults.

Conclusion:

Older adults demonstrate favourable levels of physical independence. Notably, physical activity emerges as a significant determinant positively associated with such independence. Thus, policymakers and administrators are encouraged to strategize the creation of conducive environments for walking and exercise among older adults.

Vitamin C or ascorbic acid is a water-soluble vitamin capable of directly donating electrons to reactive oxygen species, attenuating electrical remodeling, and cardiac dysfunction in patients undergoing cardiac surgery (CS), considered one of the most effective defenses against free radicals in the blood, thus being one of the first antioxidants consumed during oxidative stress. The aim of this review is to assess the effects of perioperative administration of vitamin C in CS patients. A comprehensive literature search was conducted in order to identify prospective cohort studies and/or randomized controlled trials reporting on the perioperative effects of vitamin C among adult patients undergoing CS. Studies published between January 1980 to December 2022 were included in our search, resulting in a total of 31 articles that met all our inclusion criteria. There seems to be a beneficial effect of vitamin C supplementation in arrhythmias such as in postoperative atrial fibrillation, reduction of ICU length of stay, and hospital length of stay, reduction in postoperative ventilation time, in inotropic demand, and in postoperative fatigue. Vitamin C can act as a scavenger of free radicals to decrease the peroxidation of the lipids present in the cell membrane, and to protect the myocardium postoperatively from ischemia/reperfusion injury, thus attenuating oxidative stress and inflammation. It represents a readily available and cost-effective strategy that could improve the outcome of patients undergoing CS, by reducing the risk of serious cardiovascular adverse events, both perioperatively and postoperatively.
When Vaping Isn't Actually Safer

Vape juice is a diluent for e-cigarette active ingredients, nicotine or tetrahydrocannabinol (THC). Lack of strict regulation in vape juice production is a concern as ingredients and their concentrations may vary widely from the labeling.

A 43-year-old woman was transported via ambulance to the hospital after ingesting homemade vape juice, presenting unresponsive with decerebrate posturing. She reportedly made a tincture combining a vape juice purchased online (containing “ethylene glycol”) and THC for “endometriosis-related pain relief.” Laboratory evaluation revealed anion gap metabolic acidosis, elevated serum lactate, and high serum osmolality. Urine fluoresced under Wood's lamp, and fomepizole was administered as an ethylene glycol antidote, but she expired the following afternoon. Clinical serum toxicology results returned after death revealed 235 mg/dL of methanol, and no ethylene glycol.

Autopsy findings included ischemic changes of the gastrointestinal tract and cerebral edema with herniation. Postmortem toxicology performed on hospital admission blood revealed methanol (220 mg/dL), propylene glycol (59 mg/dL), Δ-9 THC and metabolites, and medications administered during hospitalization. The medical examiner determined the cause of death to be methanol and propylene glycol toxicity.

To our knowledge, this is the first report of accidental death from ingestion of vape juice contaminated with toxic alcohol.

In September 2023, we examined requirements for budtenders working in nonmedical dispensaries in the 20 states with active non-medical cannabis markets. Two coders extracted data from each state’s licensing board and/or governmental websites. The age requirement for budtenders was ≥21 years old (n = 17) or ≥18 (n = 3). Most states (n = 16) required background checks; 10 specified felony convictions preventing employment, 5 allowed the Department to determine eligibility, and 2 allowed petitions upon denial. Twelve states required fingerprinting. There were application fees ($25-$300) in 13 states. Structured training was required in 7 states, while 5 states required employee training. Given the diverse budtender requirements, the evaluation of budtender standards is essential to assess the impacts of training on regulatory compliance and consumer education, and of application costs and conviction-based employment restrictions on social equity. This must inform the development of effective regulations and enforcement protocols, as well as and how to promote equity in cannabis regulations.

Chronic arsenic exposure is associated with adverse health outcomes, and early life exposure is particularly damaging. Households with pregnant people and young children drinking from unregulated wells in arsenic-prevalent regions are therefore a public health priority for outreach and intervention. A partnership between Columbia University, New Jersey government partners, and Hunterdon Healthcare has informed Hunterdon County residents of the risks faced from drinking arsenic-contaminated water and offered free well testing through a practice-based water test kit distribution and an online patient portal outreach. Encouraged by those successes, Hunterdon Healthcare incorporated questions about drinking water source and arsenic testing history into the electronic medical record (EMR) template used by most primary care practices in Hunterdon County. The new EMR fields allow for additional targeting of risk-based outreach and water test kit distribution, offering promising new opportunities for public health and environmental medicine outreach, surveillance, and research.

Introduction

Adult-onset Still disease (AOSD) is a rare inflammatory condition with a monophasic, intermittent, or chronic clinical course, and a subset may experience life-threatening complications such as hemophagocytic lymphohistiocytosis (HLH). This study aims to characterize concurrent AOSD and HLH and identify variables independently associated with in-hospital death.

Methods

We performed a medical records review of AOSD with and without HLH from the 2016–2019 National Inpatient Sample database. We performed a multivariable logistic regression analysis for in-hospital death. Results were reported as adjusted odds ratios (ORadj).

Results

There were 5495 hospitalizations with AOSD, of which 340 (6.2%) had HLH. Thirty (9.0%) of the combined AOSD and HLH group died in the hospital compared with 75 (1.5%) of those without HLH. Multivariable analysis in AOSD inpatients showed that disseminated intravascular coagulation (ORadj 6.13), hepatic failure (ORadj 7.16), infection (ORadj 3.72), respiratory failure (ORadj 6.89), and thrombotic microangiopathy (ORadj 14.05) were associated with higher odds of death. However, HLH itself was not an independent predictor of mortality in AOSD population.

Conclusions

HLH occurred in a small minority of inpatients with AOSD. HLH itself was not an independent risk factor for in-hospital death. Disseminated intravascular coagulation, hepatic failure, infection, respiratory failure, and thrombotic microangiopathy were associated with higher odds of in-hospital death in AOSD. Better awareness of these life-threatening complications may improve hospital outcomes.
