IgA vasculitis, formerly known as Henoch–Schönlein purpura (HSP), is the most common systemic vasculitis in children. It is defined as palpable purpura in the absence of coagulopathy or thrombocytopenia and one or more of the following criteria: abdominal pain, arthritis or arthralgia, biopsy of affected tissue demonstrating predominant IgA deposition, and renal involvement with proteinuria and hematuria or red cell casts [1].

Stevens-Johnson Syndrome (SJS), or toxic epidermal necrolysis, is a rare syndrome that develops after an allergic reaction to a medication [1,2]. It affects the skin and the mucocutaneous tissue. Individuals diagnosed with SJS are rarely referred to a rehabilitation medicine (RM) facility.

The annual prevalence of SJS is about one in one million. The skin is covered with blisters. Usually, it affects about 10 % of body surface area. The patients are treated usually by ophthalmologists, dermatologists, allergologists, and immunologists. When severe complications occur, plastic surgeons and intensive care physicians may also be involved. Few publications were found that linked SJS with comprehensive rehabilitation treatment [3-5].

Late, preterm premature rupture of the membranes (PPROM) presents a major obstetrical challenge balancing between iatrogenic prematurity and risk of prolonged rupture of membranes. In recent years, the pendulum has been shifting toward expectant management until gestation week 37 + 0. We examined the latest guidelines and major trials and summarized optimal management. We addressed the major dilemmas of women with PPROM during gestation weeks 34 + 0 to 36 + 6.

Background: Clinical investigations of long-term effects of coronavirus disease 2019 (COVID-19) are rarely translated to objective findings.

Objectives: To assess the functional capacity of individuals reported on deconditioning that hampered their return to their pre-COVID routine.

Methods: Assessment included the 6-minute walk test (6MWT) and the 30-second sit-to-stand test (30-STST). We compared the expected and observed scores using the Wilcoxon signed-rank test. Predictors of test scores were identified using linear regression models.

Results: We included 49 individuals, of whom 38 (77.6%) were recovering from mild COVID-19. Twenty-seven (55.1%) individuals had a 6MWT score lower than 80% of expected. The average 6MWT scores were 129.5 ± 121.2 meters and 12.2 ± 5.0 repeats lower than expected scores, respectively (P < 0.001 for both). The 6MWT score was 107.3 meters lower for individuals with severe COVID-19 (P = 0.013) and rose by 2.7 meters per each 1% increase in the diffusing capacity of carbon monoxide (P = 0.007). The 30-STST score was 3.0 repeats lower for individuals who reported moderate to severe myalgia (P = 0.038).

Conclusions: Individuals with long COVID who report on deconditioning exhibit significantly decreased physical capacity, even following mild acute illness. Risk factors include severe COVID-19 and impaired diffusing capacity or myalgia during recovery.

Background: The coronavirus disease 2019 (COVID-19) pandemic has severe consequences in terms of mortality and morbidity. Knowledge of factors that impact COVID-19 may be useful in the search for treatments.

Objectives: To determine the effect of glucose-6-phosphate dehydrogenase (G6PD) deficiency on morbidly and mortality associated with COVID-19.

Methods: All patients admitted to Hadassah Hebrew University Medical Center between 01 March 2020 and 03 May 2021 with a diagnosis of COVID-19 were included. We retrospectively retrieved demographic, clinical, and laboratory data from the hospital’s electronic medical records. The main outcomes were mortality, intensive care unit (ICU) admission, and severity of COVID-19.

Results: The presence of G6PD deficiency emerged as an independent protective predictor for ICU admission (odds ratio [OR] 0.258, 95% confidence interval [95%CI] 0.077–0.619, P = 0.003) and the development of critical illness (OR 0.121, 95%CI 0.005–0.545, P = 0.006). Moreover, patients with G6PD deficiency had a trend toward lower mortality rates that did not reach statistical significance (OR 0.541, 95%CI 0.225–1.088, P = 0.10).

Conclusions: Patients with G6PD deficiency were less likely to have a severe disease, had lower rates of ICU admission, and trended toward lower mortality rates.

Background: Several approaches are used to access the hip joint; most common are the direct lateral and posterior. Little consensus exists on which to use when treating hip fractures.

Objectives: To compare short-term complications, postoperative ambulation, and patient-reported outcome measures (PROMS) of direct lateral vs. posterior approaches in hemiarthroplasty for acute hip fractures.

Methods: We conducted a retrospective clinical trial with 260 patients who underwent bipolar hemiarthroplasty in the direct lateral or posterior approach (166 and 94, respectively) between January 2017 and December 2018. The clinical data included short-term complications: prosthetic dislocation, periprosthetic fractures, and infection. Postoperative ambulation was collected 6 weeks postoperatively; PROMS were collected for 173 patients at 2 years follow-up.

Results: There were six dislocations overall, average time to dislocation was 22 days postoperative (range 4–34). Five dislocations were after the posterior approach (5.3%) and one after direct lateral (0.6%) (P = 0.01). At 6 weeks follow-up, inability to walk was found in 16.9% of the direct lateral group and 6.4% of the posterior approach group (P = 0.02). In the posterior approach group, 76% could walk more than 20 meters; only half of the direct lateral group could (P = 0.0002). At 2 years follow-up, PROMS did not show a statistically significant difference between the groups.

Conclusions: Posterior approach for hemiarthroplasty following femoral neck fractures allows superior ambulation to the direct lateral approach only for the short-term. However, no long-term clinical advantage was found. This short-term benefit does not justify the increased dislocation rate in the posterior approach.

Background: Implant-based breast reconstruction (IBR) is the most common method of reconstruction for breast cancer. Bacterial infection is a well-known risk with reported rates ranging from 1% to 43%. The most common pathogens of breast implant infection described in the literature are Staphylococcus aureus, Staphylococcus epidermidis, and coagulase-negative staphylococci. However, the prevalence of other pathogens and their antibiotic sensitivity profile differs profoundly in different parts of the world.

Objectives: To review the current literature and protocols with respect to our region and to determine a more accurate antibiotic protocol aimed at our specific local pathogens.

Methods: A retrospective review was conducted of all cases of clinically infected implant-based breast reconstruction in our institution from June 2013 to June 2019, as well as review of microbiologic data from around the world based on current literature.

Results: A total of 28 patients representing 28 clinically infected implant-based breast reconstruction were identified during the studied period. Thirteen patients (46.4%) had a positive bacterial culture growth, with P. aeruginosa being the most common microorganism identified (46.1%). Review of international microbiological data demonstrated significant variation at different places and time periods.

Conclusions: Microbiological data in cases of infected breast reconstructions should be collected and analyzed in every medical center and updated every few years due to the variations observed. These data will help to adjust the optimal empirical antibiotic regimens given to patients presenting with infections after breast reconstruction.

Background: Acute appendicitis (AA) is a medical emergency. The standard of care for AA had been surgical appendectomy. Recently, non-operative management (NOM) has been considered, mainly for uncomplicated AA.

Objectives: To evaluate AA NOM trends over two decades.

Methods: We conducted a retrospective cohort study based on Israel’s National Hospital Discharges Database (NHDD). Inclusion criteria were AA admissions from 1 January 2000 to 31 December 2019, with either primary discharged diagnosis of AA, or principal procedure of appendectomy. Predefined groups were children (5 ≤ 18 years) and adults (≥ 18 years). We compared the last decade (2010–2019) with the previous one (2000–2009).

Results: The overall AA incidence rate over two decades was 126/100,000/year; higher in children 164/100,000/year than 113/100,000/year in adults. Surgery was the predominant AA treatment in 91.9%; 93.7% in children and 91.1% in adults. There was an increase in AA NOM rates when comparing the previous decade (5.6%) to the past decade (10.2%); 3.2% vs. 9.1% in children and 6.8% vs. 10.7% in adults, respectively. Annual trends revealed a mild increase in AA NOM rates. Delayed appendectomy (within 90 days of AA NOM) was 19.7% overall; 17.3% in adults and 26.3% in children.

Conclusions: There was an increase in AA NOM rates during the last decade in the overall population. Since 2015, there has been a noticeable increase in AA NOM rates, probably associated with World Society of Emergency Surgery Jerusalem guidelines. Surgery is still the predominant treatment for AA despite the increasing trend in NOM.

Background: Previous epidemiological studies on shoulder instability evaluated specific and relatively small subgroups of patients.

Objectives: To determine the incidence rate of primary shoulder dislocations.

Methods: Cohort analysis of electronic health records from 2004 to 2019 was conducted in a urban district of a major health maintenance organization (HMO) in Israel. Patients presented with primary shoulder dislocation that was treated with closed reduction in any medical facility within the district. Overall incidence density rates (IDR) of primary shoulder dislocations and stabilization surgeries were determined.

Results: Over a period of 16 years 13,158 patients underwent closed reduction of primary shoulder dislocation. Of those, 712 shoulder stabilization surgeries were performed (5%). The IDR of primary shoulder dislocations were 124 per 100,000 person-years. The IDR of primary shoulder stabilizations were 7 per 100,000 person-years. The peak in the number of dislocations was observed in those 20–29 years old and ≥ 60 years of. In patients under 59 years old, dislocations were more common in men. In those ≥ 60 years of age, dislocations were more common in women. Most shoulder stabilization surgeries were performed on young patients. The annual mean time from the first dislocation to stabilization surgery linearly declined to 6 months in 2019.

Conclusions: The IDR of primary shoulder dislocations calculated from the largest HMO in Israel were 124 per 100,000 person-years. Shoulder dislocations had bimodal age distribution. Overall, 5% of the patients (mainly young) with shoulder dislocations underwent shoulder stabilization surgery during the study period.

Background: Surgical resection is the only curative option for gastric carcinoma (GC). Minimally invasive techniques are gaining popularity.

Objectives: To present a single-surgeon's experience in transitioning from an open to a minimally invasive approach, focusing on surgical and oncological outcomes.

Methods: We conducted a retrospective analysis including distal gastrectomy patients 2012–2020 operated by a single surgeon. Two cohorts were compared: open (ODG) and laparoscopic distal gastrectomy (LDG).

Results: Overall, 173 patients were referred for gastrectomy during the study years. We excluded 80 patients because they presented with non-GC tumors, underwent proximal or total gastrectomy, or underwent palliative surgery. Neoadjuvant treatment was administered to 62 patients (33.3%). Billroth 1 was the preferred method of reconstruction (n=77, 82.8%), followed by Roux-en-Y (n=12, 13%). Fifty-one patients (54.8%) underwent LDG, 42 (45.2%) underwent ODG. The LDG group had significantly shorter lengths of stay (6 days, interquartile range [IQR] 1–3 5–8 vs. 5 days, IQR 1–3 4–6, P = 0.001, respectively), earlier return to oral feeding (1 day, IQR 1–3 1–3 vs. 2 days, IQR 1–3 1–3.2, P < 0.001), and earlier removal of drains (4 days, IQR 1–3 3–5.2 vs. 5 days, IQR 1–3 3.5–6.7, P < 0.001). Overall lymph node yield was 30 (IQR 1–3 24–39) and was similar among groups (P = 0.647).

Conclusions: Laparoscopic techniques for resection of distal GC are feasible and safe, leading to good perioperative outcomes and adequate lymph node yield.

Background: Diagnosis of onychomycosis is based on potassium hydroxide (KOH), direct smear, culture, and polymerase chain reaction. Nail clippings are rarely used as a diagnostic tool.

Objectives: To evaluate nail clippings for the diagnosis of onychomycosis and to compare it to KOH smears.

Methods: Nail clipping specimens of 39 patients were collected: 34 with onychomycosis proved by positive culture and 5 from normal nails. The specimens were submitted to histological processing and then stained with periodic acid–Schiff (PAS) and Grocott-Gomori's methenamine silver (GMS) stains. For each nail, KOH smear was also performed. Two pathologists who had no information on the KOH smear and the culture results evaluated the nail clipping histology for the presence of fungal element. Their assessment was compared to the KOH smear and culture results.

Results: Of the 34 specimens that had positive culture, 25 were dermatophytes, 5 were molds, and 4 were candida. Clipping specimens were positive in 30 cases (88%): 23/25 dermatophyte, 4/5 molds, and 3/4 candida. Pathologists were able to classify the pathogens into dermatophytes and non-dermatophytes based on the morphology. PAS stain results were the same as GMS in evaluation of the nail specimen. KOH smear was positive in 29 nails (85%): 20/25 dermatophytes, all 5 molds, and 4 candida. In all five nails where the culture was negative, both clipping and KOH smear did not show fungal elements.

Conclusion: Nail clippings can serve as a rapid, inexpensive, and reliable method for evaluation of onychomycosis, comparable to KOH smear, with the advantage of pathogen group identification.

Background: Anal squamous cell carcinoma (ASqCC) is a rare malignancy, traditionally treated with combined chemoradiation, with a continuous infusion of 5-fluorouracil (5-FU) and mitomycin C (MMC). Replacing intravenous (IV) 5-FU with oral capecitabine (oral fluoropyrimidine) has been reported as a non-inferior treatment option. However, these data are scarce, with variable results.

Objectives: To examine the outcome of patients with ASqCC treated with either IV 5-FU or capecitabine concomitantly with radiation therapy. To compare treatment side effects, local recurrence, and general outcome.

Methods: We reviewed charts of patients who were diagnosed with stage I–III ASqCC. All participating patients received chemoradiation at the Assuta Medical Center between 2011 and 2019.

Results: In this study, 43 patients with ASqCC were eligible; 14 received 5-FU and 29 were treated with capecitabine. Basic characteristics were similar between the two groups, with longer follow-up for the 5-FU group. Six months following treatment, 100% (13/13 with adequate follow-up) of the 5-FU group had complete clinical response, compared to 84% in the capecitabine group (21/24), P = 0.143. The local recurrence incidence was higher in the 5-FU group at 23% (7, 10, 26 months following therapy, and none in the capecitabine group (P = 0.088). Although local and hematological toxicities were similar between groups, one patient receiving capecitabine died during chemoradiotherapy.

Conclusions: Oral capecitabine demonstrated non-inferior disease control in ASqCC treated with chemoradiotherapy. We recommend oral capecitabine over continuous IV 5-FU in locally and locally advanced ASqCC. Close monitoring of side effects is required to reduce major toxicity.

Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1-RA) are new antidiabetic drugs that are recommended by current guidelines as a class I novel glucose-lowering treatment that improves cardiovascular outcome in type 2 diabetes mellitus (T2DM), particularly in patients with cardiovascular disease.

Objectives: To evaluate adherence to the current guidelines for treatment with SGLT2i and GLP1-RA drugs in patients referred to ambulatory consultant cardiology clinics with pre-existing T2DM.

Methods: We studied consecutive new patients with a pre-existing diagnosis of T2DM who were referred to the Clalit Health Services ambulatory consultant cardiology clinic over a 6-month period. The recorded information included demographics, co-morbidities, and prescribed drugs at patient admission.

Results: During the study period, 1782 patients visited our outpatient cardiology clinic. At screening, T2DM was present in 428 patients (24%); 77 (18%) were being treated with SGLT2i, and 39 (9.1%) with GLP1-RA. Patients receiving SGLT2i and GLP1-RA were younger and had more coronary artery disease, lower mean left ventricular ejection fraction, and higher mean estimated glomerular filtration rates than those who were not receiving these drugs. HbA1C was > 7 in 205 (47.9%) patients and > 7.5 in 136 patients (31.8%). Body mass index was > 30 kg/m² in 231 (54%) patients.

Conclusions: GLP1-RA and SGLT2i drugs were found to be administered more frequently than previously reported, but they are not yet satisfactorily prescribed.

Background: Due to the high variability in malignancy rate among cytologically indeterminate thyroid nodules (Bethesda categories III–V), the American Thyroid Association recommends that each center define its own categorical cancer risk.

Objectives: To assess cancer risk in patients with cytologically indeterminate thyroid nodules who were operated at our center.

Methods: In a retrospective study, we analyzed the pathology results of all the patients whose fine needle aspiration results showed Bethesda III–V cytology and who subsequently underwent total thyroidectomy or lobectomy from December 2013 to September 2017.

Results: We analyzed 56 patients with indeterminate cytology on fine needle aspiration. Twenty-nine (52%) were defined as Bethesda III, 19 (34%) Bethesda IV, and 8 (14%) Bethesda V category. Malignancy rates were 38%, 58%, and 100% for Bethesda categories III, IV, and V, respectively. Most malignancies in Bethesda categories III and IV were follicular in origin (follicular thyroid carcinoma and follicular type papillary thyroid carcinoma), while 100% of the patients with Bethesda category V were diagnosed with classical papillary thyroid carcinoma. No correlation was found between sonographic and cytological criteria of nodules with Bethesda categories III and IV and rates of malignancy.

Conclusions: We found higher than expected rates of malignancy in indeterminate cytology. This finding reinforces the guidelines of the American Thyroid Association to establish local malignancy rates for thyroid nodules with indetermined cytology.

Twenty years after being closed due to unfavorable results, a new lung transplant program was started at the Sheba Medical Center. The new team included an experienced lung transplant surgeon, an anesthesiologist, an intensive care specialist, and a pulmonologist with extensive experience in the field.
