Abstract

Introduction:
Aortic regurgitation (AR) was recognized as a major, but rare complication after device closure for perimembranous ventricular septal defects (PmVSD). Most of them are temporary and non-significant. Infectious endocarditis (IE) is another extremely rare post-procedure complication of PmVSD. Theoretically, AR could increase risk for post-interventional IE. However, no cases have been documented thus far. We firstly described a case of very late-onset IE associated with non-significant AR after transcatheter closure of PmVSD with modified symmetrical double-disk device, underscoring the need for reassessing long-term prognostic implications of non-significant post-procedure AR after PmVSD occlusion and the most appropriate treatment strategy.

Patient concerns:
A 15-year old male received transcatheter closure of a 6.4 mm sized PmVSD with a 9-mm modified symmetric double-disk occluder (SHAMA) 11 years ago in our hospital. A new-onset mild eccentric AR was noted on transthoracic echocardiography (TTE) examination 1-year post procedure, without progression and heart enlargement. At this time, the child was admitted with a complaint of persistent fever for 16 days and nonresponse to 2-weeks course of amoxicillin and cefoxitin.

Diagnosis:
The diagnosis of post-procedure IE was established since a vegetation (14 × 4 mm) was found to be attached to the tricuspid valve, an anechoic area (8 × 7 mm) on left upper side of ventricular septum and below right aortic sinus, and severe eccentric AR as well as the isolation of Staphylococcus aureus from all three-blood cultures.

Interventions:
Treatment with vancomycin was initially adopted. However, surgical interventions including removal of vegetation, abscess and occluder, closure of VSD with a pericardial patch, tricuspid valvuloplasty, and aortic valvuloplasty were ultimately performed because of recurrent fever and a new-onset complete atrioventricular block 12-days later. The child continued with antibiotic therapy up to six weeks post operation.

Outcomes:
The child's temperature gradually returned to normal with alleviation of AR (mild) and heart block (first degree). The following course was uneventful.

Conclusion:
Late-onset IE could occur following device closure of PmVSD and be associated with post-procedure AR. For non-significant AR after device closure of PmVSD, early surgical intervention could be an alternative for reducing the aggravation of aortic valve damage and the risk of associated IE.

Abstract
To evaluate the utility of unenhanced postmortem computed tomography (PMCT) for the investigation of in-hospital nontraumatic death in children up to 3 years of age.
This study included the cadavers of children who died from intrinsic diseases before 3 years of age. The major underlying disease and the main organ–disease systems associated with the immediate causes of death were determined by clinical evaluation, PMCT, and autopsy, which were used as a reference standard. The rates of concordance between the former two methods and autopsy were calculated for all cases.
In total, 22 cadavers (12 male and 10 female; mean age, 6.1 ± 8.2 months) were included. The rates of concordance between clinical evaluation/PMCT and autopsy for diagnosis of the major underlying disease and main organ–disease systems associated with the immediate causes of death were 100%/36% (P = .0015) and 59%/41% (P = .37), respectively. In cases where the respiratory system was associated with the immediate cause of death, PMCT showed greater diagnostic sensitivity (90%) than did clinical evaluation (20%). In contrast, the diagnostic sensitivity of PMCT was lower than that of clinical evaluation in cases involving disorders of the cardiac system and multiple organ systems (0% vs 100% for both).
The findings of this study suggest that the use of unenhanced PMCT with clinical evaluation can result in improved detection of the immediate cause of death in select cases of in-hospital nontraumatic death before 3 years of age.
Arthroscopic labral debridement versus labral repair for patients with femoroacetabular impingement

Abstract

Objective:
Femoroacetabular impingement (FAI) is a common cause of hip pain and even tearing of the acetabular labrum in young adults and athletes. Either arthroscopic labral debridement (LD) or labral repair (LR) technique for FAI patients is needed to choose. We conducted this systematic review and meta-analysis to compare the clinical outcomes of arthroscopic LD versus LR intervention.

Methods:
The five studies were acquired from PubMed, Medline, Embase, and Cochrane Library. The data were extracted by two of the coauthors independently and were analyzed by RevMan5.3. Mean differences (MDs), odds ratios (ORs), and 95% confidence intervals (CIs) were calculated. Cochrane Collaboration's Risk of Bias Tool and Newcastle–Ottawa Scale were used to assess risk of bias.

Results:
Four observational studies and one prospective randomized study were assessed. The methodological quality of the trials indicated a low to moderate risk of bias. The pooled results of Non-Arthritic Hip Score (NAHS), failure rate of surgeries and complications showed that the differences were not statistically significant between the two interventions. The difference of modified Harris Hip Score (mHHS), the Visual Analogue Scale (VAS) score and satisfaction rate was statistically significant between LD and LR intervention, and LR treatment was more effective. Sensitivity analysis proved the stability of the pooled results and there were too less included articles to verify the publication bias.

Conclusions:
Hip arthroscopy with either LR or LD is an effective treatment for symptomatic FAI. The difference of mHHS, VAS score, and satisfaction rate was statistically significant between LD and LR intervention, and arthroscopic LR could re-create suction-seal effect, potentially reduce microinstability, which demonstrated a trend toward better clinical efficacy and comparable safety compared with LD. The arthroscopic LR technique is recommended as the optical choice for acetabular labrum tear with FAI.
Motor recovery of hemiparetic leg by improvement of limb-kinetic apraxia in a chronic patient with traumatic brain injury
Authors: Choi Eun Bi , Kim Jun Young , Jang Sung Ho 
Published: May 2020

Abstract

Rationale:
Limb-kinetic apraxia (LKA), a kind of apraxia, means the inability to perform precise and voluntary movements of extremities resulting from injury of the premotor cortex (PMC) or the corticofugal tract (CFT) from the PMC. Diagnosis of LKA is made by observation of movements without specific assessment tools.

Patient concerns:
A 44-year-old male underwent conservative management for traumatic intracerebral hemorrhage in the left basal ganglia and subarachnoid hemorrhage due to a pedestrian-car crash. When he was admitted to the rehabilitation department of a university hospital after 41 months after onset, he presented with right hemiparesis (Medical Research Council (MRC): shoulder abductor; 3, elbow flexor; 3, finger extensor; 0, hip flexor; 2- [range: 30°], knee extensor; 1 and ankle dorsiflexor; 3-). In addition, he exhibited slow, clumsy, and mutilated movements when performing movements of his right ankle.

Diagnoses:
The patient was diagnosed as traumatic brain injury (TBI).

Interventions:
Clinical assessments and DTI were performed at 41 and 44 months after onset. During three months, rehabilitative therapy was performed including dopaminergic drugs (pramipexole 2.5 mg, ropinirole 2.5 mg, and amantadine 300 mg, and carbidopa/levodopa 75 mg/750 mg).

Outcomes:
The right leg weakness slowly recovered during 3 months, until 44 months after the initial injury (MRC: shoulder abductor, 3; elbow flexor, 3; finger extensor, 0; hip flexor, 3; knee extensor, 3; and ankle dorsiflexor, 3+). The fiber number of the right corticospinal tract (CST) was decreased on 44-month diffusion tensor tractography (DTT) (1319) compared with 41-month DTT (1470) and the left CST was not reconstructed on both DTTs. The fiber number of both CRTs were decreased on 44-month DTT (right: 1547, left: 698) than 41-month DTT (right: 3161, left: 1222).

Lessons:
A chronic patient with TBI showed motor recovery of the hemiparetic leg by improvement of LKA after rehabilitation. This results have important implications for neurorehabilitation.

Abstract
To investigate the effect of multi-disciplinary teamwork on balance performance of Parkinson's disease (PD).
Sixteen primary Parkinson's disease patients (8 male, 8 female) treated with bilateral subthalamic nucleus deep brain stimulation (STN-DBS) were included in the study. The median age of patients was 60.5 years; all patients were in the Hoehn&Yahr (H&Y) 3 stage; the median PD duration of the disease was 9 years. For each patient, multi-disciplinary teamwork treatment including DBS, medication, physical therapy and psychotherapy proceeded. levodopa equivalent daily dose (LEDD, mg/day), life quality (PDQ-39), Motor disability (MDS-UPDRSIII) and balance performance (MDS-UPDRS 3.12, Berg Balance Scale BBS, Limits of Stability LoS) were assessed in different time and status respectively: preoperation (Med-off, Med-on), postoperation (Stim-Off/Med-Off, Stim-On/Med-Off, Stim-On/Med-On), 6 months postoperation (Stim-On/ Med-Off, Stim-On/Med-On) and 12 months postoperation (Stim-On/Med-Off, Stim-On/Med-On).
The LEDD, life quality (PDQ-39) continued to improve during the follow-up, statistical difference were found in both 6 months postoperation and 12 months postoperation compared with preoperation. The Motor disability (MDS-UPDRSIII), balance performance (MDS-UPDRS 3.12, BBS) and the LoS (target acquisition percentage, trunk swing angle standard deviation, time) showed significant improvement in Stim-On/med-Off 6 months postoperation and 12 months postoperation separately compared with Med-Off preoperation.
Multi-disciplinary teamwork for PD patients with STN-DBS could improve balance performance.

Abstract

Background:
Chinese herbal bath has long been used in the curative treatment of psoriasis vulgaris. However, there is no unified standard protocol for Chinese herbal bath. Many factors affect the curative effect of Chinese herbal bath, such as water temperature, bath concentration, and soaking time. Most studies involving Chinese herbal bath has described the bath generally, and few studies have investigated the factors that might contribute to the efficacy of Chinese herbal bath. Here we describe a protocol to evaluate the efficacy and safety of various bathwater temperatures and herbal concentrations on psoriasis vulgaris, and their effect on serum vascular endothelial growth factor (VEGF), tumor necrosis factor α (TNF-α), interleukin 23 (IL-23), and interleukin 17 (IL-17). These data could be useful for optimizing Chinese herbal bath treatments.

Methods:
In this randomized controlled trial, we planned to recruit 288 hospitalized atients with psoriasis vulgaris aged 18 to 65 years. All participants who meet the inclusion criteria will be randomly assigned to the observation group, the control group, or the basic treatment group. The observation group will be divided into 6 sub-groups according to water temperatures and bath concentrations, designated as observation groups 1 to 6. Thirty-six participants will be assigned to each group. The basic treatment group will be given co-qingdai capsule, po 2 g tid; compound glycyrrhizin tablet, po 75 mg tid; AA Skincare jojoba Oil, us.ext qd. The observation group will be given a Chinese herbal bath at the same time as the basic treatment. The control group will be given ozone hydrotherapy at the same time as the basic treatment. The entire treatment course will last for 2 weeks. The following parameters will be compared in each group, before and 2 weeks after treatment: the psoriasis area and severity index score (PASI), pruritus score, clinical efficacy, and dermatology life quality index score (DLQI); serum levels of serum VEGF, TNF-α, IL-23, and IL-17; and confocal laser scanning microscope images.

Conclusion:
This study will evaluate the efficacy and safety of various Chinese herbal bath conditions (water temperatures and herbal concentrations) on the treatment of psoriasis vulgaris, which will provide an important reference for the operation of Chinese herbal bath.

Abstract
We aim to explore the relationship between early-onset diabetes and proliferative diabetic retinopathy (PDR) in type 2 diabetes mellitus (T2DM) patients with microalbuminuria.
A total of 461 T2DM patients with microalbuminuria were enrolled. Subjects were defined as early-onset or late-onset based on the age at which they were diagnosed with diabetes (<40 and ≥40 years, respectively). Medical history, anthropometry, and laboratory indicators were documented. PDR was defined as the presence of any of the following changes on fundus photography: neovascularization, vitreous hemorrhage, or preretinal hemorrhage.
The prevalence of PDR was 6-fold higher in patients with early-onset than late-onset T2DM [(6.1% vs 1.0%), P = .004]. Univariate correlation analysis showed that early-onset diabetes, use of oral hypoglycemic drugs, and insulin therapy were risk factors for PDR. In multivariate logistic analysis, patients with early-onset diabetes exhibited a 7.00-fold [(95% confidence interval 1.40–38.26), P = .019] higher risk of PDR than subjects with late-onset diabetes after adjusting for sex; T2DM duration; systolic blood pressure; total triglyceride; glycated hemoglobin; insulin therapy; and the use of oral hypoglycemic drugs, antihypertensive drugs, and lipid-lowering drugs.
In T2DM patients with microalbuminuria, early-onset diabetes is an independent risk factor for the development of PDR.
Novel coronavirus 2019 (COVID-19)
Authors: Douedi Steven , Miskoff Jeffrey 
Published: May 2020

Abstract

Rationale:
Novel coronavirus 2019 (COVID-19) also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an enveloped, non-segmented positive-sense RNA virus belonging to the beta-coronaviridae family. This virus is known to cause severe bilateral pneumonia and acute respiratory distress syndrome (ARDS) which can lead to difficulty breathing requiring mechanical ventilation and intensive care unit management.

Patient concerns:
A 77-year-old female with a history of hypertension and hyperlipidemia who presented as a transfer to our hospital facility with worsening fevers, cough, and respiratory distress.

Diagnosis:
Chest X-rays revealed bilateral infiltrates worse at the lung bases and CT scan of the chest showed bilateral ground-glass opacities consistent with COVID-19. While our testing revealed a negative COVID-19 result at our institution, the result at a previous hospital returned a positive result.

Interventions:
She was being treated aggressively in the intensive care unit with high dose intravenous ascorbic acid, hydroxychloroquine, and anti-interleukin-6 monoclonal antibody. She also received a loading dose of remdesivir however was unable to complete the course due to organ failure and requirement of vasopressors for hemodynamic stability.

Outcomes:
She remained critically ill and was eventually placed on comfort care as per the family's wishes and passed away.

Lessons:
With a rapidly growing death rate and more than 200,000 confirmed cases worldwide, COVID-19 has become a global pandemic and major hit to our healthcare systems. While several companies have already begun vaccine trials and healthcare facilities have been using a wide-range of medications to treat the virus and symptoms, there is not yet an approved medication regimen for COVID-19 infections. The alarming increase in cases per day adds additional pressure to find a cure and decrease the global health burden and mortality rate.

Abstract
To explore the clinical features and management of post-necrotizing enterocolitis strictures.
Clinical data from 158 patients with post-necrotizing enterocolitis strictures were summarized retrospectively in 4 academic pediatric surgical centers between April 2014 and January 2019. All patients were treated conservatively in the internal medicine department. All patients underwent preoperative X-ray examinations, 146 patients underwent gastrointestinal contrast studies, and 138 patients underwent rectal mucosal biopsies. All of the patients were treated surgically.
Of the 158 patients, 40 of them had necrotizing enterocolitis (NEC) Bell stage Ib, 104 had Bell stage IIa, and 14 had Bell stage IIb. In these patients, the clinical signs of intestinal strictures occurred at mean of 47.8 days after NEC. In 158 patients, 146 underwent barium enema examination, 116 demonstrated intestinal strictures, and 10 demonstrated microcolon and poor development. A total of 138 patients underwent rectal mucosal biopsies, and 5 patients had Hirschsprung disease. Intraoperative exploration showed that intestinal post-NEC strictures occurred in the ileal (17.7%, 28/158) and colon (82.3%, 130/158), including ascending colon, transverse colon and descending colon, and multiple strictures were detected in 36.1% (57/158) patients. Surgical resection of stricture segments in the intestine and primary end-to-end anastomosis were performed in 142 patients, and the remaining 16 patients underwent staged surgeries. In the 146 patients with complete follow-up data, 9 had postoperative adhesions: 4 of them received conservative treatment, and the others underwent a second operation. Fifteen patients were hospitalized 1 to 3 times for malnutrition and dehydration due to repeated diarrhea; these patients eventually recovered and were discharged smoothly. All the other patients had uneventful recoveries without stricture recurrence.
Post-NEC strictures mostly occurred in the colon, and there were some cases of multiple strictures. A gastrointestinal contrast study was the preferred method of examination. Preoperative rectal mucosal biopsy resulted in a diagnosis of Hirschsprung disease, and then a reasonable treatment protocol was chosen. Surgical resection of stricture segments in the intestine and primary end-to-end anastomosis achieved good therapeutic effects with favorable prognoses in these patients.

Abstract
Remifentanil is the most frequently prescribed opioid for total intravenous anesthesia (TIVA) or balanced anesthesia (BA), due to its favorable pharmacological properties. However, several studies have reported opioid-induced hyperalgesia and/or acute tolerance after intraoperatively using remifentanil. In addition, it is imperative to control postoperative pain with lower doses of opioid anesthetic agents. Therefore, we compared the amount of opioid consumption between TIVA with propofol-remifentanil and BA with desflurane-remifentanil, to control postoperative pain in patients who underwent laparoscopic-assisted distal gastrectomy (LADG) with gastroduodenostomy.
We retrospectively evaluated demographic variables (age, gender, height, weight, and smoking habits), the duration of general anesthesia (GA), and intraoperatively administered remifentanil consumption through the electronic medical records of patients who underwent LADG with gastroduodenostomy due to early stomach cancer. The primary outcome was postoperative opioid consumption during postoperative day (POD) 2. The secondary outcomes were the incidence of any rescue opioid analgesics administered, numeric rating scale, and various adverse effects during POD 2. We categorized the data in 2 patient groups to compare TIVA with propofol-remifentanil (TIVA group) to BA with desflurane-remifentanil (BA group) on the postoperative opioid analgesic consumption.
We divided 114 patients into the TIVA (46 patients) and BA (68 patients) groups. Opioid consumption as a primary outcome was significantly higher in the BA group than in the TIVA group during POD 2 except in the post-anesthesia care unit. The cumulative opioid consumption was significantly higher in the BA than in the TIVA group. The incidence of rescue analgesic at POD 2 was higher in the BA than in the TIVA group. In the TIVA group, remifentanil consumption was higher, and the duration of GA was shorter than that in the BA group. No statistically significant differences were observed when comparing other variables.
Our results indicated that the maintenance of GA with TIVA (propofol-remifentanil) reduces opioid consumption for postoperative pain control compared to BA (desflurane-remifentanil) in patients undergoing LADG with gastroduodenostomy.
