A 69-year-old woman with a 30-year history of rheumatoid arthritis (RA) on leflunomide presented with dizziness and weakness. Vital signs, cardiopulmonary auscultation, and laboratory studies were normal. The serological status of her RA was unknown. She exhibited ulnar deviation and swan-necking of the hands but no nodular skin lesions. She was an active smoker. Chest radiography revealed an opacity in the right lung. Computed tomography (CT) showed multiple pulmonary nodules and a dominant thick-walled cavitary mass in the periphery of the right lower lobe [Figure 1A]. Due to concern for a malignancy or infection, she underwent a bronchoscopy with a biopsy of the mass, which was non-diagnostic. A subsequent transthoracic needle biopsy demonstrated a central zone of necrosis surrounded by a cuff of palisading epithelioid histiocytes with the presence of occasional giant cells [Figure 1B]. There was no malignancy, and stains for micro-organisms were negative. In this clinical context, biopsy results were consistent with a pulmonary rheumatoid nodule (PRN).

Background: The French AmbUlatory Cesarean Section (FAUCS) technique was introduced to the Galilee Medical Center in September 2021. FAUCS was performed electively for interested women who meet the criteria.

Objectives: To evaluate the learning curve of senior surgeons performing FAUCS, the procedure short-term outcomes, and complications.

Methods: This retrospective study included 50 consecutive women who underwent FAUCS from September 2021 until March 2022 at our facility. Preoperative, intraoperative, postoperative, and demographic data were retrieved from patient electronic charts.

Results: The mean duration of surgery was 53.26 ± 11.62 minutes. This time decreased as the surgical team's experience increased: from a mean 58.26 ± 12.25 minutes for the first 15 procedures to a mean 51.17 ± 9.73 minutes for subsequent procedures. The mean visual analogue scale score for 24 hours was 1.08 ± 0.84 (on a 10-point scale). The rate of neonatal cord pH < 7.2 was 6%, and there were 11.3% cases of vacuum assisted fetal extraction. In total, 44% of the women were able to mobilize and urinate spontaneously by 4–6 hours. Complications included bladder injury (n=1), endometritis (n=1), and incisional hematoma (n=1). Overall, the maternal satisfaction rate was high; 94% of the women would recommend FAUCS to others.

Conclusions: FAUCS is a feasible procedure with a high satisfaction rate. Following the first 15 procedures performed by one surgical team, the operative time decreased considerably. Further randomized controlled studies are needed to compare this procedure to regular cesarean section and evaluate neonatal outcomes.

Background: Older age is an independent predictor of worse outcome from traumatic brain injury (TBI). No clear guidelines exist for the management of TBI in elderly patients.

Objectives: To describe the outcomes of elderly patients presenting with TBI and intracranial bleeding (ICB), comparing a very elderly population (≥ 80 years of age) to a younger one (70–79).

Methods: Retrospective analysis of the outcomes of elderly patients presenting with TBI with ICB admitted to a level I trauma center.

Results: The authors analyzed 100 consecutive patients aged 70–79 and 100 patients aged 80 and older. In-hospital mortality rates were 9% and 21% for groups 70–79 and ≥ 80 years old, respectively (P = 0.017). Patients 70–79 years old showed a 12-month survival rate of 73% and a median survival of 47 months. In patients ≥ 80 years old, 12-month survival was 63% and median survival was 27 months (P = NS). In patients presenting with a Glasgow Coma Scale score of ≥ 8, the in-hospital mortality rates were 41% (n=5/12) and 100% (n=8/8). Among patients ≥ 80 years old undergoing emergent surgical decompression, in-hospital mortality was 66% (n=12/18). Survivors presented with a severe drop in their functional score. Survival was dismal in patients ≥ 80 years old who were treated conservatively despite recommended operative guidelines.

Conclusions: There is a lack of reliable means to evaluate the outcome in patients with poor functional status at baseline. The negative prognostic impact of severe TBI is profound, regardless of treatment choices.

Background: Young women concerned about a breast cancer diagnosis will visit breast care centers and request breast cancer screening, including imaging studies, on their initial visit.

Objectives: To explore the role of breast examination and breast ultrasound in self-referred asymptomatic women under the age of 40 years.

Methods: We identified 3524 women under the age of 40 at our medical clinic from 1 January 2010 until 1 June 2014. Of this group, 164 women with above average breast cancer risk were excluded and 233 were excluded because of breast complaints. Of 3127 women, 220 underwent breast ultrasound following the initial visit to the clinic and formed the study group.

Results: Of 220 women evaluated with ultrasound, 68 had prior positive clinical findings. Of this group 8 women had no sonographic findings, and in the remaining 60, a total of 30 simple cysts, 15 fibroadenomas, and 15 suspicious solid masses were identified. One infiltrating ductal carcinoma and one ductal carcinoma in situ were found in a biopsy. The remaining 152 of the 220 total women who underwent breast ultrasound without showing prior physical findings did not require follow-up.

Conclusions: In the absence of clinical findings during physical breast examination, the addition of breast ultrasonography does not provide additional information to supplement the physical examination in self-referred women under age 40 who do not have any major risk factors for developing breast cancer.

Background: The number of patients undergoing shoulder arthroplasty is increasing yearly.

Objectives: To evaluate the results of a consecutive series of patients who underwent shoulder replacement for a variety of indications in a single medical center in Israel.

Methods: All shoulder arthroplasties performed in our institution between 2006 and 2015 were retrospectively reviewed. The functional outcomes and satisfaction of 180 shoulder arthroplasties were evaluated for objective and subjective parameters using the American Shoulder and Elbow Surgeons Shoulder Score (ASES), the Disabilities of the Arm, Shoulder and Hand (DASH) outcome measure, and the Short Form Health Survey (SF-12).

Results: The indications for surgery were osteoarthritis (n=35), rotator cuff arthropathy (n=32), fractures (n=99), and other reasons (n=14). The mean follow-up was 52 months. The scores improved markedly among the patients who underwent surgery later in the study period. The mean DASH score before 2012 was 48.8 and improved to 37.2 after 2013. The respective ASES also improved from 54.2 to 68.6. The use of hemiarthroplasty decreased from 85% to 33% as of 2013, while the use of total shoulder arthroplasty increased.

Conclusions: Shoulder arthroplasty represents an effective treatment modality with satisfactory functional outcomes. Our current study demonstrates a shift from hemiarthroplasty to total shoulder arthroplasty, with the number of procedures increasing yearly. Surgeon experience and the expanding volume of operations had a direct positive effect on the functional outcomes of shoulder arthroplasties.

Background: Cachibol (known as kadureshet in Hebrew) is a team ball game whose characteristics are similar to those of volleyball. The game is becoming increasingly popular, particularly among adult women and is the fastest growing female sport in Israel. Despite its growing popularity, data on the epidemiology of injuries incurred from this sport are sparse. 

Objectives: To investigate the incidence and severity of injuries among adult female cachibol players.

Methods: We conducted a cross-sectional survey and observational cohort study of 612 amateur female cachibol players participating in a 3 day national tournament; 355 players completed questionnaires relating to traumatic injuries incurred during previous cachibol activity (58% response rate). All injuries sustained during the tournament were reported. 

Results: Fingers were the most commonly injured part of the body, mostly due to a direct hit by the ball. Finger injuries, though considered mild, may have long-term implications: over 50% of the injured players reported long-term finger discomfort. After finger injuries, ankles and knees were the second most commonly injured parts of the body, with a higher rate of absence from sports activity and work and for a longer time compared to finger injuries. 

Conclusions: Due to the unique characteristics of cachibol, the rate of finger injuries is higher in this game than in volleyball. Injuries are a growing cause for concern in view of the rapidly increasing number of cachibol players. Our findings may be useful for developing effective injury prevention programs for cachibol players.

 

Background: The popularity of bicycle riding for recreation, exercise and transportation has grown enormously in recent years, which has led to an increased incidence of bicycle-related injuries. While these injuries involve mainly the musculoskeletal system, data on shoulder-specific injuries incurred while bike riding are lacking. Classifying these shoulder injuries may provide insight and assistance in the creation and implementation of effective protective gear and measures. 

Objectives: To investigate the types and mechanisms of shoulder injuries among cyclists.

Methods: This study retrospectively examined all cyclists who incurred shoulder injuries while riding and were admitted to the emergency department and shoulder clinic between January 2008 and November 2013. The study included 157 subjects with various bicycle-related shoulder injuries treated with either conservative or surgical measures. 

Results: Eighty-four percent of injuries were caused by a direct blow to the shoulder, 7% by falling on an outstretched hand, 6% were traction injuries, and 3% were due to hyper-abduction. Nine different clinical types of injury were observed; the most common injuries were clavicle fractures (32%), followed by acromioclavicular joint dislocations (22%), rotator cuff tears (22%), and humeral fractures (8%). Fifty-one percent of subjects were managed with conservative care and the remaining patients required surgical interventions. 

Conclusions: The shoulder injuries incurred while riding a bicycle span the entire spectrum of shoulder injuries and often result in debilitating conditions. Although the use of helmets is increasing, there is currently no effective protective gear or measures to prevent riders from suffering shoulder injuries. 

 

Objectives: To assess the relationship between sleep deprivation, key metabolic markers, and professional performance in medical residents.

Methods: We compared 35 residents working the in-house night shift with 35 senior year medical students in a cross-sectional cohort study. The Epworth Sleepiness Scale (ESS) questionnaire was administered and blood tests for complete blood count (CBC), blood chemistry panel, lipid profile and C-reactive protein (CRP) were obtained from all participants.

Results: Medical students and medical residents were comparable demographically except for age, weekly working hours, reported weight gain, and physical activity. The ESS questionnaires indicated a significantly higher and abnormal mean score and higher risk of falling asleep during five of eight daily activities among medical residents as compared with medical students. Medical residents had lower high density lipoprotein levels, a trend towards higher triglyceride levels and higher monocyte count than did medical students. CRP levels and other laboratory tests were normal and similar in both groups. Among the medical residents, 5 (15%) were involved in a car accident during residency, and 63% and 49% reported low professional performance and judgment levels after the night shift, respectively.

Conclusions: Medical residency service was associated with increased sleepiness, deleterious lifestyle changes, poorer lipid profile, mild CBC changes, and reduced professional performance and judgment after working the night shift. However, no significant changes were observed in CRP or in blood chemistry panel. Larger prospective cohort studies are warranted to evaluate the dynamics in sleepiness and metabolic factors over time.

Background: Carbon dioxide is the most widely used gas to establish pneumoperitoneum during laparoscopic surgery. Gastrointestinal trauma may occur during the peritoneal insufflation or during the operative phase itself. Early diagnosis of these injuries is critical.

Objectives: To assess changes in end-tidal carbon dioxide (E_TCO₂) following gastric perforation during pneumoperitoneum in the rat.

Methods: Wistar rats were anesthetized, tracheotomized and mechanically ventilated with fixed minute volume. Each animal underwent a 1 cm abdominal longitudinal incision. A 0.3 x 0.3 cm cross-incision of the stomach was performed in the perforation group but not in the controls (n=10/group), and the abdomen was closed in both groups. After stabilization, CO₂-induced pneumoperitoneum was established at 0, 5, 8 and 12 mmHg for 20 min periods consecutively, each followed by complete pressure relief for 5 minutes.

Results: Ventilatory pressure increased in both groups when pneumoperitoneal pressure ≥ 5 mmHg was applied, but more so in the perforated stomach group (P = 0.003). E_TCO₂ increased in both groups during the experiment, but less so in the perforated group (P = 0.04). It then returned to near baseline values during pressure annulation in all perforated animals but only in the 0 and 5 mmHg periods in the controls.

Conclusions: When subjected to pneumoperitoneum, E_TCO₂ was lower in rats with a perforated stomach than in those with an intact stomach. An abrupt decrease in E_TCO₂ during laparoscopy may signal gastric perforation.
 

Background: Multiple case series, mostly highly selected, have demonstrated a very high mortality following acute basilar artery occlusion. The more widespread availability and use of non-invasive vascular imaging over recent years has increased the rate of ABAO[1] diagnosis.

Objectives: To estimate the proportion of diagnosed ABAO among all-cause ischemic stroke in an era of increasing use of non-invasive vascular imaging and to compare the characteristics and outcomes between these two groups.

Methods: We compared 27 consecutive cases of ABAO identified in a university hospital between 2003 and 2007 to 311 unselected cases of ischemic stroke from two 4 month surveys.

Results: ABAO diagnosis increased from 0.3% of all-cause ischemic stroke (2003–2004) to 1.1% (2007), reflecting the increased use of non-invasive vascular imaging. In comparison to all-cause ischemic stroke, ABAO patients were younger (mean age 60 vs. 71 years), were more likely to be male (89% vs. 60%), had less atrial fibrillation (7% vs. 26%), more severe strokes (baseline NIHSS over 20: 52% vs. 12%), higher admission white cell count (12,000 vs. 9000 cells/mm³) lower admission systolic blood pressure (140 ± 24 vs. 153 ± 27 mmHg), higher in-hospital mortality rates (30% vs. 8%) and worse functional outcome (modified Rankin scale ≤ 3, 22% vs. 56%) (P < 0.05 for all). Rates of reperfusion therapy for ABAO increased from 0 in 2003–2004 to 60% in 2007.

Conclusions: In this study, ABAO patients represented approximately 1% of all-cause ischemic stroke and were about a decade younger than patients with all-cause ischemic stroke. We report a lower ABAO mortality compared to previous more selected case series; however, most survivors had a poor functional outcome. Given the marked clinical heterogeneity of ABAO, a low threshold for non-invasive vascular imaging with a view to definitive reperfusion treatment is needed.

Objectives: To assess the implementation of intravenous rt-PA[1] in routine clinical care at our center after its formal approval in Israel, and the therapeutic and logistic implications for reperfusion therapy for acute ischemic stroke in Israel.

Methods: Patients with acute ischemic stroke, admitted between January 2005 and June 2006, who were treated with intravenous rt-PA or endovascular-based reperfusion were reviewed. Implementation, timing, safety and clinical outcomes were assessed.

Results: Forty-six patients received reperfusion therapy (37 with intravenous rt-PA and 9 with endovascular-based therapy), corresponding to 4.0% of ischemic stroke patients in 2005 and a projection of 6.2% in 2006. Mean age of intravenously treated patients was 67 years (range 22–85 years), median baseline NIHSS score was 14 (range 10–18, 25–75%) and the median ‘onset to drug time’ was 150 minutes (range 120–178, 25–75%). Symptomatic intracerebral hemorrhage and orolingual angioedema each occurred in one patient (2.7%). Significant clinical improvement occurred in 54% of treated patients and 38% of patients were independent at hospital discharge.

Conclusions: Use of reperfusion therapy for acute ischemic stroke has increased in our center after the formal approval of rt-PA therapy to over 5%, with ‘onset to drug time’, safety and outcome after intravenous rt-PA treatment comparing favorably with worldwide experience. A prerequisite for the implementation of effective reperfusion therapy and expansion of the proportion of patients treated nationwide is the establishment of a comprehensive infrastructure.

Objective: To assess the effect of establishing a new dedicated acute stroke unit within a department of neurology on indicators of process of care and outcome of acute stroke in a routine clinical setting in Israel.

Methods: Stroke patients admitted to the Sheba Medical Center during the period March 2001 to June 2002 were included in a prospective study according to selection criteria. Data on demographics, risk factors, co-morbidities and stroke severity were collected. Indicators of process of care and outcome were assessed at hospital discharge and 30 days follow-up. Comparison between outcome variables by hospitalization ward was conducted using logistic regression analysis adjusting for confounders.

Results: Of 616 acute stroke patients (mean age 70 years, 61% men, 84% ischemic stroke), 353 (57%) were admitted to general wards and 263 (43%) to the stroke unit. Diagnostic procedures were performed more often, and infection rate was lower in the setting of the stroke unit. Poor outcome (modified Rankin scale ≥3 or death) was present less often in patients managed in the stroke unit both at hospital discharge (adjusted odds ratio 0.5, 95% confidence interval 0.3–0.8) and at 30 day follow-up (adjusted OR[1] 0.6, 95%CI[2] 0.3–0.9). A Functional Independence Measure score ≤90 or death at 30 day follow-up was less frequent among patients managed in the stroke unit than in general wards (adjusted OR 0.5, 95%CI 0.2–0.8).

Conclusions: Improved outcomes and higher adherence to guidelines were observed in patients treated in a stroke unit within a department of neurology. The results suggest that patients with acute stroke should have access to treatment in a dedicated stroke unit.
