Published: April 2021

Introduction Among females, breast cancer is the most common type of cancer. Hormon receptor positive (HR+) subtype constitutes 75% of the diagnosed breast cancers. Combination of the cyclin D-cyclin-dependent kinase 4/6 (CDK4/6) inhibitor and endocrine therapy significantly improves overall survival and progression-free survival. Ribociclib is an oral CDK 4/6 inhibitor and some adverse effects are identified. According to MONALEESA 2-3-7 studies, no adverse effect (AE) were reported due to grade 3 or 4 acute kidney injury (AKI) that caused treatment discontinuation. Case report We report a ribociclib-induced grade 3 AKI in an elderly woman who was treated for metastatic breast cancer. During first cycle of therapy, she was admitted to the oncology clinic with diagnosis of AKI. Management and outcome: Ribociclib treatment was discontinued and secondary causes of AKI were excluded. During the follow-up, kidney function values returned to the normal range spontaneously. Ribociclib treatment was re-initiated by reducing the dose (400 mg daily). Despite dose reduction; grade 3 AKI recurred when ribociclib was re-initiated and the drug was permanently discontinued. Discussion According to MONALEESA 2-3-7 studies; no AE were reported due to grade 3 or 4 AKI. Despite these studies, the FDA reported that 20% of patients with ribociclib + letrozole combination therapy may have any stage elevation of creatinine. Ribociclib induced creatinine elevations are generally mild (grade 1–2) and can be managed by dose reduction or close monitoring of creatinine levels. We report the first case of grade 3 AKI that caused treatment discontinuation following administration of ribociclib.

Introduction All-trans retinoic acid (ATRA) is a physiological metabolite of vitamin A and it is used for the treatment of acute promyelocytic leukemia (APL). Hypercalcemia is a rare side effect of ATRA and it may be potentiated after interaction of ATRA with azole group antifungals. Herein, we have reported an APL case with hypercalcemia that is caused by the interaction of ATRA and posaconazole. Case Report A 49-year-old female patient was diagnosed as APL after the examinations performed upon the detection of pancytopenia when she had presented with the complaints of widespread bruising and fever. After the initiation of posaconazole and ATRA, her serum calcium levels begin to increase (10.3 to 11.1mg/dl). Her vitamin D level was 21.9 ng/ml and PTH 17.8 pg/ml, both were in the normal ranges. The Drug Interaction Probability Scale score of our case was calculated as 6, indicating that the probable adverse drug reaction. Therefore, the high level of serum calcium was attributed to the interaction between ATRA and posaconazole. Management & Outcome Although hypercalcemia with ATRA and other antifungal agents have been previously reported in the literature, this is the first report of hypercalcemia with the concomitant use of ATRA and posaconazole. Discussion This case highlights the importance of monitoring ATRA’s side effects when it is used in combination with drugs inhibiting the cytochrome P450 enzymes. In conclusion, the concomitant use of posaconazole and ATRA may lead to hypercalcemia and serum calcium levels return to normal ranges with the discontinuation of these drugs.
Traumatic physeal fractures in cats: a review of 36 cases (2010–2020)
Authors: Rubinos Carlos , Meeson Richard L 
Published: April 2021

Objectives The aim of this study was to describe the demography, aetiology, location and classification of physeal fractures in cats, and to describe their management and outcomes. Methods Clinical records and radiographs of cats referred for management of physeal fractures were retrospectively reviewed. Fractures of the proximal femoral physis were excluded. Descriptive statistics were used to describe signalment, cause of injury, presence of concurrent injuries, fracture description, treatment modality, complications, follow-up, physeal closure, implant removal and outcome. Results Thirty-four cats with 36 fractures were included, of which 17 affected the distal femur, 11 the distal tibia and fibula, five the distal radius and ulna, two the proximal tibia and one the distal humerus. Salter–Harris classification was type I in 14, type II in 16, type III in two and type IV in four fractures. Thirty-four fractures were treated with primary fixation, and the most common method was crossed Kirschner wires (24/34 fractures). Complications were observed in 14 fractures, of which 12 were minor. At radiographic follow-up, physeal closure was reported in 23 fractures, of which 15 were considered premature. Implant removal was performed in three fractures. Outcome was good in 28, fair in four and poor in two fractures. Conclusions and relevance Fracture of the distal femoral physis was the most common physeal fracture seen. Cats presenting with physeal fractures may be skeletally immature or mature with delayed physeal closure. The rate of physeal closure after fracture repair was relatively high but without apparent impact. The frequency of implant removal was very low, indicating that despite having a physeal fracture repair, most cats did not require a second procedure to remove implants. Overall, internal fixation provided a good outcome in most fractures.

Purpose: This study aimed to evaluate the relationship between diabetic iridopathy (DI) and diabetic retinopathy (DR) and distinguish iris neovascular and physiological leakage using iris fluorescein angiography (IFA). Methods: A total of 210 subjects were prospectively recruited in this study. Sixty normal subjects were divided equally into three groups (<40 years old, 40–59 years old, and 60–79 years old). One hundred fifty patients with diabetic mellitus (DM) were divided equally into five groups (no retinopathy, mild non proliferative DR (mildnPDR), moderate nPDR, severe nPDR, and PDR group). Normal subjects underwent IFA. Patients with DR underwent both IFA and ultrawide field fundus fluorescein angiography (uwFFA) at the same time. The leakage time and area were recorded and compared with each group. Results: Fluorescein leakage occurred at the pupillary edge of patients that were 40–59 and 60–79 years old but not in those <40 years old. In the PDR group, the leakage time was earlier and the leakage area was larger than nPDR and patients with no retinopathy ( p = 0.039 and p = 0.005, respectively). However, the leakage time and area were not significantly different between patients with no retinopathy and nPDR ( p > 0.05). Conclusion: IFA examination can only assist in estimating the fundus severity of PDR patients, whereas the fundus changes of patients with no retinopathy and nPDR were not related to DI changes.

Published: April 2021

Background and purpose: Adding hydroxyapatite to a stem to enhance ingrowth is a matter of debate, even less is known about the long-term effect on stability by adding hydroxyapatite (HA). Continuous migration in the first 2–5 years is an indicator of failed osteointegration or pending failure, enhancing the risk of loosening within 10 years after initial surgery. We performed a double-blinded randomised RSA trial with 5-year follow-up, to compare and analyse migration characteristics of the hydroxyapatite uncoated (HA−) and hydroxyapatite coated (HA+) Zweymuller-type hip stem. Patients and methods: In this single-centre prospective randomised controlled trial 51 patients were randomised to receive either a HA− or a HA+ Zweymuller-type hip stem during total hip replacement. After 5 years, 35 patients were still eligible for follow-up evaluation. The migration pattern was measured by use of radio stereometric analysis (RSA) images up to 2 years to evaluate short-term migration, additionally RSA images were obtained 5 years postoperatively to assess late-term and continuous migration. Furthermore, the improvement of clinical outcome was analysed by HSS and HOOS ADL and pain subscales preoperative and after 5 years. Results: After initial settling of the implant, no significant migration occurred up to 5 years post-surgery for HA+ as well as HA− prostheses. Continuous migration within the 2–5 years’ time interval was not observed for both HA+ nor the HA− group in all directions ( p < 0.05). No significant difference between both groups was observed ( p < 0.10). In both groups the HHS and HOOS improved significantly at 5 years compared to baseline for both groups. Improvement was not altered by the hydroxyapatite coating. No significant difference between both groups was observed ( p > 0.58). Conclusions: Addition of a hydroxyapatite coating did not influence the migration 5 years postoperatively for the Zweymuller-type hip stem. Clinical Trial Protocol number: NL 23524.048.08

Published: April 2021

Background: Patients who commence haemodialysis (HD) through arteriovenous fistulae and grafts (AVF/G) have improved survival compared to those who do so by venous lines. Objectives: This systematic review aims to assimilate the evidence for any strategy which increases the proportion of HD patients starting dialysis through AVF/G. Data sources: Medline, Embase, Cochrane Central and Scopus. Study eligibility, participants and interventions: English language studies comparing any educational, clinical or service organisation intervention for adult patients with end stage renal failure and reporting incident AVF/G use. Study appraisal and synthesis: Two reviewers assessed studies for eligibility independently. Outcome data was extracted and reported as relative risk. Reporting was performed with reference to the PRISMA statement. Results: Of 1272 studies, 6 were eligible for inclusion. Studies varied in design and intervention. Formal meta-analysis was not appropriate. One randomised controlled trial and two cohort studies assessed the role of a renal access coordinator. Two cohort studies assessed the implementation of qualitive initiative programmes and one cohort study assessed a national, structured education programme. Results between studies were contradictory with some reporting improvements in incident AVF/G use and some no significant difference. Quality was generally low. Conclusions: It is not possible to reach firm conclusions nor make strategic recommendations. A comprehensive package of care which educates and identifies patients approaching dialysis in a timely manner may improve incident AVF/G use. An unbiased, robust comparison of different strategies for timing AVF/G referral is required.

Introduction: In Uruguay, breast cancer has the highest incidence and mortality of all cancer in women. Knowledge of the distribution of risk factors related to disease development supports the implementation of prevention strategies in routine clinical practice. This study aimed to determine the epidemiological profile for breast cancer and the frequency of mammographic surveillance in the surveyed population. Materials and Methods: A survey was conducted among Uruguayan women diagnosed with breast cancer who were assisted in the mastology unit of the oncology service of the Hospital de Clínicas in Montevideo, Uruguay, from September 1, 2018, to March 1, 2020. Results: This study included 398 respondents, with a median (SD) age at diagnosis of 61 (34-86) years. A total of 310 respondents (78.0%) had 1 or more risk factors. Most women aged over 50 years (264 out of a total of 338 [78.1%]) underwent mammographic surveillance at least biennially. Conclusions: Consistent with international reports, most respondents had a risk factor. Among the group of respondents aged over 50 years, most underwent mammographic and clinical surveillance at least biennially. Although it is only possible to formulate conclusions about the surveyed women because of the study design, the obtained data further our understanding of the epidemiological profile of the Uruguayan population, which can contribute to prevention practices.

Published: April 2021

Background Persons with multiple sclerosis (pwMS) experience walking impairments, characterized by decreased walking speeds. In healthy subjects, the self-selected walking speed is the energetically most optimal. In pwMS, the energetically most optimal walking speed remains underexposed. Therefore, this review aimed to determine the relationship between walking speed and energetic cost of walking (Cw) in pwMS, compared with healthy subjects, thereby assessing the walking speed with the lowest energetic cost. As it is unclear whether the Cw in pwMS differs between overground and treadmill walking, as reported in healthy subjects, a second review aim was to compare both conditions. Method PubMed and Web of Science were systematically searched. Studies assessing pwMS, reporting walking speed (converted to meters per second), and reporting oxygen consumption were included. Study quality was assessed with a modified National Heart, Lung and Blood Institute checklist. The relationship between Cw and walking speed was calculated with a second-order polynomial function and compared between groups and conditions. Results Twenty-nine studies were included (n = 1535 pwMS) of which 8 included healthy subjects (n = 179 healthy subjects). PwMS showed a similar energetically most optimal walking speed of 1.44 m/s with a Cw of 0.16, compared with 0.14 mL O2/kg/m in healthy subjects. The most optimal walking speed in treadmill was 1.48 m/s, compared with 1.28 m/s in overground walking with a similar Cw. Conclusion Overall, the Cw is elevated in pwMS but with a similar energetically most optimal walking speed, compared with healthy subjects. Treadmill walking showed a similar most optimal Cw but a higher speed, compared with overground walking.

Introduction: The pandemic produced by SARS-CoV-2 has obliged us to set up the tele-assistance to offer a continuity of care. This implies an innovation, being the degree of satisfaction of patients unknown. Methods: A telephonic survey was conducted with the validated in the Spanish tool Telehealth Usability Questionnaire (Telehealth Usability Questionnaire; rating from 1-7) of all candidate patients assisted consecutively in the Coloproctology Unit. We included demographic variables, education level, job status, diagnosis and consultation type. A descriptive study was done. The relationship between the willingness of consultation model in the future (telemedicine vs traditional) and the categorical variables was analysed through the chi-squared test. Results: A total of 115 patients were included. The average age was 59.9 years, being 60% women. The average score in each of the survey items was higher than 6 in all the questions but 1. 26.1% of the surveyed patients confessed being advocated to tele-assistance in the future. The only factors related to greater willingness to tele-assistance were male gender (37% vs 18.8%; P = .03) and a higher academic preparation level in favour of higher technical studies (35.9%) and university studies (32.4%) opposite to the rest ( P = .043). The rest of variables studied, job status, labour regimen, diagnostic group and consultation type did not show any relationship. Conclusions: A vast majority of patients answered favourably to almost all the items of the survey. However, only 26.1% of them would choose a model of tele-assistance without restrictions.
Unusual pediatric epidural arteriovenous fistula with venous ectasia presented with spontaneous spinal epidural hematoma: Case report
Authors: Niimi Yasunari , Sato Shinsuke , Ryu Bikei , Inoue Tatsuya , Shima Shogo 
Published: April 2021

Background Spontaneous spinal epidural hematoma (SSEH) is rare in children. Vascular malformation including arteriovenous fistulas and venous malformation is a rare cause of SSEH. Case description A 5-year-old girl presented with 2 episodes of SSEH at the upper thoracic spine and non-hemorrhagic episodes with spontaneous neurological recovery. Diagnostic study with MRI and spinal angiography demonstrated an unusual epidural arteriovenous fistula (AVF) with venous ectasia similar to venous malformation. She underwent embolization of the AVF with NBCA with mild transient neurological deterioration. Follow up angiography showed persistent occlusion of the embolized fistula and inconsistent visualization of another AVF to the patent venous ectasia. Conclusions This type of epidural AVF seems to be more common in children and tends to cause multiple neurologic episodes due to SSEH, venous expansion or thrombosis. Endovascular embolization with NBCA should be the first choice of treatment for this disease, unless emergent hematoma evacuation is necessary. Embolization should target at only the fistula site without significant penetration into the venous ectasia. Follow up is necessary for potential reappearance of AVF, even if AVF is occluded at the time of treatment. Time resolved MRI is useful to detect AVFs, thus for diagnosis and follow up of this disease.

Background and Aims: Although noninferior to stent retriever (SR) as first-line approach for endovascular treatment (EVT) of acute large vessel occlusion (LVO) stroke, little is known about the current status of direct aspiration (DA) as first-line thrombectomy in China. This analysis of a prospective, nationwide registry (ANGEL-ACT) aimed to investigate the prevalence and comparative effectiveness of DA-first thrombectomy in a real-world practice in China. Methods: All patients receiving thrombectomy were screened from a prospective cohort of LVO patients undergoing EVT at 111 hospitals in China between November 2017 and March 2019, and divided into two groups based upon which type of thrombectomy was attempted first (“DA-first” and “SR-first”). The following outcome measures were compared using logistic regression models with adjustment: successful recanalization after first-device alone and all procedures, use of rescue treatment, intracranial hemorrhage (ICH) within 24 h, and modified Rankin Scale (mRS) score at 90 days. Results: A total of 1225 patients, 102 (8.3%) in DA-first group and 1123 (91.7%) in SR-first group, were included. Patients receiving DA-first had less often successful recanalization after first-device alone [30.4 versus 66.4%; odds ratio (OR) = 0.23, 95% confidence interval (CI) = 0.15–0.37], more frequent rescue treatment (62.8 versus 27.0%; OR = 4.55, 95% CI = 2.92–7.08) and ICH (35.4 versus 22.1%; OR = 1.78, 95% CI = 1.12–2.83) than those receiving SR-first; however, no significant difference was found in successful recanalization after all procedures (84.3 versus 90.3%; p = 0.18) and 90-day mRS (median: 3 versus 3 points; p = 0.90) between both groups. Conclusion: This real-world registry suggested that DA-first thrombectomy for acute stroke patients lagged behind in China during the study period. Far fewer DA-first than SR-first thrombectomies were performed, and DA-first was associated with lower first-device recanalization, more frequently requiring rescue treatment, and increased ICH risk.

Published: April 2021

Background: The quality of data in electronic health records (EHRs) depends on adherence of clinicians to principles of diagnosis documentation. Objective: A concept mapping (CM) approach was used to extract factors related to quality of clinicians’ documentation that govern EHR data quality. Method: Influential factors extracted from brainstorming sessions were sorted by individual participants, followed by a quantitative analysis using multidimensional scaling and cluster analysis to categorise sorted factors. Finally, a questionnaire was used to elicit the importance-feasibility of the extracted factors. Results were visualised by cluster maps and Go-Zone plots. Result: Factors were classified into seven clusters: “knowledge about International Classification of Diseases and clinical coding,” “need for facilitators and guidelines,” “explaining the importance of the issue and defining responsibilities,” “cooperation of other personnel,” “codify legal requirements,” “workload” and “clinical obstacles,” as ranked by importance. Conclusion: To enhance the quality of EHR data, a collaboration between physicians, nurses, managers and EHR developers is required. CM is an acceptable approach to meet this objective. Our findings highlight the significance of clinical coding knowledge, awareness about its importance and applicability and use of well-structured information systems. In combination, these three factors can have a strong positive impact on the quality of EHR data. Implications: A list of solutions is provided for policymakers, and two interventions suggested, based on the findings of this study, including the adoption of EHRs that incorporate documentation guidelines. We further propose updated clinical training programs and a monitoring and feedback mechanism to facilitate the EHR documentation process.
