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: 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: Type 2 diabetes mellitus (T2DM) is a known risk factor for cardiovascular disease and stroke. Metformin is an old, relatively safe, first line therapy for T2DM; however, it has been associated with stroke.

Objectives: To study the effects of metformin use and vitamin B12 deficiency on stroke rate among patients with T2DM.

Methods: We conducted a prospective study of patients admitted with ischemic stroke within 12 months (starting March 2020). We studied the clinical impact of metformin on vitamin B12 deficiency and stroke evolution. Student's t-test and ANOVA were used to compare the groups of patients and to determine whether there was any direct or indirect effect of metformin use on vitamin B12 deficiency and stroke.

Results: In total, 80 patients were admitted with ischemic stroke. Clinical status and biochemical data were collected and compared with healthy volunteers. There were 39 diabetic patients, 16 took metformin for at least 1 year. Among those who took metformin for at least 1 year, 9 had vitamin B12 level < 240 pg/ml (56.2%); 23 diabetic patients did not get metformin and only 4 had vitamin B12 level < 240 pg/ml (17.4%) (P = 0.014).

Conclusions: T2DM is a significant risk factor to the development of ischemic stroke. We found an association between metformin use and vitamin B12 deficiency and an association between vitamin B12 deficiency and stroke risk in patients with T2DM. Diabetic patients who are taking metformin should monitor their vitamin B12 level.

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.

Takotsubo syndrome (TTS) often develops following stressors such as cardiac surgery. It may be fatal in rare cases. Our 70-year-old female patient presented with a rare case of tricuspid valve papillary fibroelastoma, which was complicated by fatal TTS after successful resection. The patient had a right atrial mass that was investigated with computed tomography and transesophageal echocardiography (TTE). She was scheduled for surgery. Pathology findings were consistent with papillary fibroelastoma of the tricuspid valve. Three weeks after successful surgery, the patient was admitted due to cardiogenic shock with echocardiographic findings of apical ballooning and left ventricular outflow tract obstruction consistent with TTS. The patient died one hour after her admission despite optimal medical therapy.

Background: Clinical dysentery causes hundreds of thousands of deaths annually worldwide. However, current recommendations reserve antibiotics for those either clinically sick or with highly suspected cases of shigellosis. This treatment stems from rising antibiotic resistance. Children diagnosed with clinical dysentery in the pediatric emergency department (PED) are regarded more cautiously.

Objectives: To explore the use of antibiotics in children diagnosed with clinical dysentery in the PED.

Methods: A retrospective case study of children with clinical dysentery at a single PED during the years 2015 and 2018. Demographics as well as clinical findings were compared to culture results and antibiotic treatment.

Results: The study included 281 children who were diagnosed with clinical dysentery during the study period; 234 (83%) were treated with antibiotics. However, cultures were positive in only 162 cases (58%). Only 32% were Shigella spp. Younger age, fever, and leukocytosis were related to antibiotic treatment.

Conclusions: The diagnosis of clinical dysentery is misgiven commonly in the PED leading to widespread use of antibiotics when not indicated. This treatment may impact antibiotic resistance patterns. Further studies and interventions are necessary to create clear guidelines in the PED setting.

Background: Acquired hepatocerebral degeneration (AHD) is a neurologic complication of severe chronic liver disease (CLD) with portosystemic shunts. The proposed etiology is manganese accumulation in the brain tissue, especially in the basal ganglia. Combination of clinical manifestation, mostly extrapyramidal movement disorders, and hyperintensities on T1-weighted brain magnetic resonance imaging (MRI) is diagnostic. Although liver transplantation controversial, it is suggested for AHD.

Objectives: To depict clinical and neuroimaging characteristics and response to treatments in patients diagnosed with AHD at Sheba Medical Center.

Methods: Review of patients with AHD diagnosis at the Liver Diseases Center at Sheba Medical Center between 2012 and 2017, data of clinical and neuroimaging, follow-up, and response to treatments, including liver transplantation were recorded.

Results: Five patients with diagnosis of AHD were identified, median age at diagnosis 55 years (range 45–64 years). Four patients had cirrhosis at the time of AHD diagnosis. The main risk factor for AHD was the presence of portosystemic shunts. The most prevalent clinical manifestations were movement disorders, specifically a combination of extrapyramidal and cerebellar signs including instability, rigidity, tremor, bradykinesia, and cognitive impairment. Brain MRI revealed hyperintensities on T1-weighted images in the basal ganglia in all patients. Administration of antiparkinsonian drugs showed clinical improvement, whereas liver transplantation performed in two patients was not associated to neurological improvement.

Conclusions: AHD is related to portosystemic shunts. The combination of Parkinsonism and cerebellar signs and MRI pallidal lesions should alert physicians to the diagnosis. The role of liver transplantation in AHD is still controversial.

Background: Polyp detection rate (PDR) is a convenient quality measure indicator. Many factors influence PDR, including the patient's background, age, referral (ambulatory or hospitalized), and bowel cleansing.

Objectives: To evaluate whether years of professional experience have any effect on PDR.

Methods: A multivariate analysis of a retrospective cohort was performed, where both patient- and examiner-related variables, including the experience of doctors and nurses, were evaluated. PDR, as the dependent variable was calculated separately for all (APDR), proximal (PPDR), and small (SPDR) polyps.

Results: Between 1998 and 2019, 20,996 patients underwent colonoscopy at a single center. After controlling for covariates, the experience of both doctors and nurses was not found to be associated with APDR (odds ratio [OR] 0.99, 95% confidence interval [95%CI] 0.98–1.00, P = 0.15 and OR 1.03, 95%CI 1.02–1.04, P < 0.0001, respectively). However, after 2.4 years of colonoscopy experience for doctors, and 9.5 years of experience for nurses, a significant increase in APDR was observed. Furthermore, results revealed no association for PPDR and SPDR, as well.

Conclusions: Years of colonoscopy experience for both doctors and assisting nurses were not associated with APDR, PPDR, and SPDR. In doctors with 2.4 years of experience and nurses with 9.5 years of experience, a significant increase in APDR was observed.

Background: Population screening for the BRCA mutations in Ashkenazi Jewish women was recently implemented in Israel and is expected to lead to a 10-fold increase in the diagnosis of asymptomatic carriers. Performing the screening follow-up within multidisciplinary dedicated clinics for carriers is recommended for early detection and risk reduction.

Objectives: To determine the availability, capacity, and practices of dedicated screening clinic for BRCA carriers in Israel.

Methods: A telephone-based survey of all public hospitals in Israel was conducted October 2020 to August 2021 to determine whether they had a dedicated clinic. Dedicated clinics were defined as multidisciplinary screening clinics offering at least breast and gynecological screening and risk reducing services on site. The clinic director or nurse navigator answered a questionnaire about screening practices followed by a semi-structured interview.

Results: Of the ten dedicated BRCA clinics found in Israel, nine participated. Approximately 4500 BRCA carriers are currently being followed. No specialized clinics are available in the southern district or in the northernmost half of the northern district of Israel, leading to a disparity between periphery and center. Screening recommendations, although asserted as adhering to international guidelines, vary among clinics including age at initiating of clinical exam, use of adjunct imaging modalities, and follow-up during lactation and after risk reducing surgery.

Conclusions: There is a suboptimal distribution of dedicated clinics for BRCA carriers in Israel. Nationally centralized attempt to create guidelines that will unify screening practices is warranted, especially considering the expected increase in demand.

Background: Advances in examination techniques have improved routine assessment of non-gynecological structures in the pelvis.

Objectives: To describe the sonographic features of incidental urological abnormalities found during gynecological transvaginal ultrasound.

Methods: A retrospective descriptive analysis of patients who underwent gynecological ultrasound and were diagnosed with urologic findings was performed. The sonographic features of the findings including size, echogenicity, and vascularity were examined.

Results: Gynecological ultrasound diagnosed urological findings in nine women. Two had primary neoplasms of the urinary bladder, one had metastases to the urinary bladder, one had polyps in the distal ureters, four presented with calculus in the distal ureters (one of them was 19 weeks pregnant), and one showed diverticulum of the urethra. At presentation five women (56%) had urinary complaints. Two patients (22%) with abdominal pain with distal ureteral calculi had normal transabdominal ultrasound targeted to the urinary system prior to the gynecological sonography.

Conclusions: Transvaginal ultrasound is useful in the diagnosis of urological abnormalities, mainly in the urinary bladder and the distal ureters. We suggest adding transvaginal assessment for female patients with urinary complains in whom transabdominal ultrasound of urinary system was unremarkable.

Background: Higher body mass index (BMI) has been shown to be a protective factor from mortality in sepsis patients. Yet, whether this effect is different in the very elderly is currently unknown.

Objective: To investigate the relationship between BMI and sepsis outcomes in patients older and younger than 80 years of age.

Methods: A retrospective analysis of consecutive patients admitted with sepsis to Shamir Medical Center, Israel, was conducted. We compared patients older than and younger than 80 years of age with a BMI higher and lower than 25 kg/m² for hospitalization outcomes.

Results: Patients older than 80 years presented with multiple co-morbidities compared to younger patients, but with no difference between BMI groups. Similarly, hospitalization outcomes of functional deterioration, discharge to long-term care facilities, and readmission were not significantly different between BMI groups in the same age category. Mortality was significantly different between BMI groups in patients older than 80 years of age, with higher mortality in BMI < 25 kg/m²: in-hospital mortality (23.4% vs. 14.9%, P < 0.001), 30-day mortality (27.6% vs. 17.9%, P < 0.001), and 90-day mortality (43.4% vs. 28.9%, P < 0.001). This difference was not significant between the groups younger than 80 years old. On logistic regression, BMI over 25 kg/m² was protective in all mortality categories. Nevertheless, there was no significant interaction between age over 80 years to BMI over 25 kg/m² in all mortality outcomes.

Conclusions: Among patients hospitalized with sepsis, higher BMI is a protective factor against mortality in both elderly and younger patients.

Background: Unilateral intratonsillar abscess (ITA) is an underreported, well-known complication of acute tonsillitis. The prevalence of unilateral ITA compared to peritonsillar abscess (PTA) is 1:14. However, bilateral ITA is an extremely rare entity, with only four cases reported thus far.

Objectives: To describe past cases and our experience, elaborating the diagnostic challenge and the surgical treatment for bilateral ITA.

Methods: We conducted a literature search in the PubMed database using the key words intra-tonsillar abscess, tonsillar abscess, bilateral tonsillar abscess, bilateral intra-tonsillar abscess and bilateral peritonsillar abscess. Our search was limited to the years 1980 to 2020.

Results: We found that only four cases of bilateral ITA were previously published. All were characterized by a delay in diagnosis with a median of 10 days (4–14 days), symmetrical oral cavity appearance, enlarged bilateral kissing tonsils, and subsequent treatment by surgical drainage/paracentesis. Respiratory compromise was a concern in most cases. Our patient was treated with bilateral quinsy tonsillectomy and had a prompt recovery.

Conclusions: Bilateral ITA is a rare, deceiving entity, with a diagnosis delay attributed to the symmetrical oral bulging. We present the fifth case reported and the first ever reported in a pediatric patient. We describe the assumed pathogenesis and the main characteristics among all five patients, emphasizing the important role of a high index of suspicion and appropriate imaging, guiding to proper diagnosis and treatment.

Background: The prognosis of long-term clinical outcomes for each patient is of utmost importance.

Objectives: To evaluate the association between rates of family attendance during rounds and long-term outcomes.

Methods: We conducted a historic cohort study.

Results: We followed 200 consecutive patients for a median of 19 months. Within the group of patients that had family members present in > 75% of rounds, the 30-day re-hospitalization rate was tenfold higher (P = 0.017). The overall prognosis (including median survival length) of patients who had the highest rates of family attendance (> 75%) was significantly worse compared to patients who had lower rates (P = 0.028). High rates of family attendance were found to correlate with other established risk factors for long-term mortality, including advanced age (r = 0.231, P = 0.001) and in-hospital delirium.

Conclusions: High family attendance during physician rounds in an internal medicine department is associated with worse patient prognosis.

Background: Serasis® (Serag-Wiessner KG, Naila, Germany) is a light-weight mid-urethral sling for treating stress urinary incontinence (SUI). Its insertion is considered less traumatic than other mid-urethral slings.

Objectives: To define postoperative outcomes following Serasis implantation. To compare the efficacy and complication rates of the implant to those of other common techniques.

Methods: Our retrospective study evaluated patients who underwent Serasis mid-urethral sling surgery for SUI. Data were collected from medical records prior to and at the time of surgery and by telephonic interview for postoperative pain and complications. Follow-up of patients was performed for up to one year postoperatively. Patients rated pain or discomfort according to the Visual Analogue Scale (VAS). The primary outcome was the development of early postoperative pain during the first month after surgery. Secondary outcomes were relief of SUI symptoms, groin pain or discomfort, and other postoperative complications up to 12 months after surgery.

Results: The study cohort included 50 consecutive patients aged 31 to 68 years. All patients underwent Serasis implantation procedures by a single surgeon and completed interviews. In total, 35 patients underwent concomitant anterior colporrhaphy. In the immediate postoperative period and at one month after the procedure, complaints were mild. No complaints were recorded during the 12-month follow-up period. Overall, 90% and 92% of the patients were free of SUI symptoms at one month and 12 months after surgery, respectively.

Conclusions: Serasis mid-urethral sling is safe, effective, and associated with mild postoperative pain and a low incidence of complications.

Acute cholecystitis is a common surgical diagnosis. If not addressed properly, it can potentially lead to sepsis, perforation of the gallbladder, and even death.

The most frequent pathogens isolated from bile cultures of patients with cholecystitis are anaerobes and Enterbacterales such as E. coli, Klebsiella species, and Streptococcus species [1].

Streptococcus gordonii belongs to the Viridians streptococci group of oral bacteria and is commonly associated with dental caries. S. gordonii has been previously reported as the causative pathogen in both endocarditis and spondylodiskitis [2]. However, it has rarely been associated with biliary infections. In this report, we presented a patient diagnosed with cholecystitis associated with S. gordonii infection.
