Background: Dietary modifications and patient-tailored medical management are significant in controlling renal stone disease. Nevertheless, the literature regarding effectiveness is sparse.

Objectives: To explore the impact of dietary modifications and medical management on 24-hour urinary metabolic profiles (UMP) and renal stone status in recurrent kidney stone formers.

Methods: We reviewed our prospective registry database of patients treated for nephrolithiasis. Data included age, sex, 24-hour UMP, and stone burden before treatment. Under individual treatment, patients were followed at 6–8 month intervals with repeat 24-hour UMP and radiographic images. Nephrolithiasis-related events (e.g., surgery, renal colic) were also recorded. We included patients with established long-term follow-up prior to the initiation of designated treatment, comparing individual nephrolithiasis status before and after treatment initiation.

Results: Inclusion criteria were met by 44 patients. Median age at treatment start was 60.5 (50.2–70.2) years. Male:Female ratio was 3.9:1. Median follow-up was 10 (6–25) years and 5 (3–6) years before and after initiation of medical and dietary treatment, respectively. Metabolic abnormalities detected included: hypocitraturia (95.5%), low urine volume (56.8%), hypercalciuria (45.5%), hyperoxaluria (40.9%), and hyperuricosuria (13.6%). Repeat 24-hour UMP under appropriate diet and medical treatment revealed a progressive increase in citrate levels compared to baseline and significantly decreased calcium levels (P = 0.001 and 0.03, respectively). A significant decrease was observed in stone burden (P = 0.001) and overall nephrolithiasis-related events.

Conclusions: Dietary modifications and medical management significantly aid in correcting urinary metabolic abnormalities. Consequently, reduced nehprolithiasis-related events and better stone burden control is expected.

Fetal complete atrioventricular block (CAVB) is usually autoimmune mediated. The risk of developing CAVB is 2% to 3% in anti-Ro/SS-A seropositive pregnancies and it increases 10 times after previous CAVB in siblings. Despite being a rare complication, CAVB carries a 20% mortality rate and substantial morbidity, as about 65% of newborns will eventually need life-long pacing. Once found, fetal CAVB is almost always irreversible, despite aggressive immunotherapy. This poor outcome prompted some research groups to address this situation. All groups followed anti-Ro/SS-A seropositive pregnancies on a weekly basis during the second trimester of pregnancy and tried to detect first degree atrioventricular block (AVB) using accurate echocardiographic tools, assuming they may characterize the initiation of the immune damage to the A-V conduction system, at which point the process might still be reversible. Some of the groups treated fetuses with first degree AVB with maternal oral fluorinated steroids. We summarized the results of all groups, including our group. We describe a case of a fetus that developed CAVB 6 days after normal sinus rhythm (NSR), who under aggressive dexamethasone therapy gradually reverted to NSR. This fetus had a previous sibling with CAVB. We assumed the immune damage to the conduction system in this small group of fetuses with a previous CAVB sibling may have occurred more quickly than usual. We therefore recommend a twice-weekly follow-up with these fetuses

Background: Sheba Medical Center, Tel Hashomer, is a tertiary hospital located in the center of Israel. It is the largest hospital in Israel and was the first to face coronavirus disease-2019 (COVID-19) patients in the country at the beginning of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic.

Objectives: To describe our experience with the COVID-19 pandemic, focusing on our triage method in the emergency department (ED). Our goal was to keep the main hospitalization buildings clean of infection by separating COVID-19 positive patients from COVID-19 negative patients.

Methods: We divided our ED into two separate sections: a regular non-COVID-19 ED and an advanced biological ED. We created clear protocols of triage for suspected and confirmed COVID-19 patients. We reviewed the data of patients admitted to our ED during the month of March and analyzed the results of our triage method in separating COVID-19 positive from negative patients.

Results: During the month of March 2020, 7957 patients were referred to our ED. Among them 2004 were referred to the biological ED and 5953 were referred to the regular ED. Of the 2004 patients referred to the biological ED, 1641 (81.8%) were sampled for SARS-CoV-2 polymerase chain reaction of whom 143 (8.7%) were positive. Only two COVID-19 positive patients unintentionally entered the main clean hospital, making our triage almost full proof.

Conclusions: Our triage method was successful in separating COVID-19 positive from negative patients and maintained the regular hospital clean of COVID-19 allowing treatment continuation of regular non-COVID-19 patients.

Background: Social distancing, implemented to decrease the spread of coronavirus disease-2019 (COVID-19), forced major changes in medical practices, including an abrupt transition from face-to-face to remote patient care. Pre-clinical medical studies were concomitantly switched to electronic distance learning.

Objectives: To explore potential implications of COVID-19 on future pre-clinical medical studies.

Methods: We examined responses of pre-clinical medical students to the remote electronic learning in terms of quality of and satisfaction with teaching and technical support, attendance to classes, and the desire to continue electronic learning in the post-epidemic era. A survey of responses from first-year students at the Adelson School of Medicine was conducted. To optimize the reliability of the survey, a single research assistant conducted telephone interviews with each student, using a structured questionnaire concerning aspects of participation and satisfaction with teaching and with technical components of the remote electronic learning.

Results: With 100% response rate, the students reported high satisfaction with the electronic learning regarding its quality, online interactions, instructions given, technical assistance, and availability of recording for future studies. Most of the students (68.6%) noted a preference to continue < 90% of the learning online in the post-outbreak era. A high level of overall satisfaction and a low rate of technical problems during electronic learning were significantly correlated with the desire to continue online learning (P < 0.01).

Conclusions: The high satisfaction and the positive experience with the electronic distance learning imposed by the COVID-19 epidemic implied a successful transition and might induce future changes in pre-clinical medical studies.

Background: Abdominal tumors invading the inferior vena cava (IVC) present significant challenges to surgeons and oncologists.

Objectives: To describe a surgical approach and patient outcomes.

Methods: The authors conducted a retrospective analysis of surgically resected tumors with IVC involvement by direct tumor encasement or intravascular tumor growth. Patients were classified according to level of IVC involvement, presence of intravascular tumor thrombus, and presence of hepatic parenchymal involvement.

Results: Study patients presented with leiomyosarcomas (n=5), renal cell carcinoma (n=7), hepatocellular carcinoma (n=1), cholangiocarcinoma (n=2), Wilms tumor (n=1), neuroblastoma (n=1), endometrial leiomyomatosis (n=1), adrenocortical carcinoma (n=1), and paraganglioma (n=1). The surgeries were conducted between 2010 and 2019. Extension of tumor thrombus above the hepatic veins required a venovenous bypass (n=3) or a full cardiac bypass (n=1). Hepatic parenchymal involvement required total hepatic vascular isolation with in situ hepatic perfusion and cooling (n=3). Circular resection of IVC was performed in five cases. Six patients had early postoperative complications, and the 90-day mortality rate was 10%. Twelve patients were alive, and six were disease-free after a mean follow-up of 1.6 years.

Conclusions: Surgical resection of abdominal tumors with IVC involvement can be performed in selected patients with acceptable morbidity and mortality. Careful patient selection, and multidisciplinary involvement in preoperative planning are key for optimal outcome.

Background: In February 2020, the World Health Organisation designated the name COVID-19 for a clinical condition caused by a virus identified as a cause for a cluster of pneumonia cases in Wuhan, China. The virus subsequently spread worldwide, causing havoc to medical systems and paralyzing global economies. The first COVID-19 patient in Israel was diagnosed on 27 February 2020.

Objectives: To present our findings and experiences as the first and largest center for COVID-19 patients in Israel.

Methods: The current analysis included all COVID-19 patients treated in Sheba Medical Center from February 2020 to April 2020. Clinical, laboratory, and epidemiological data gathered during their hospitalization are presented.

Results: Our 162 patient cohort included mostly adult (mean age of 52 ± 20 years) males (65%). Patients classified as severe COVID-19 were significantly older and had higher prevalence of arterial hypertension and diabetes. They also had significantly higher white blood cell counts, absolute neutrophil counts, and lactate dehydrogenase. Low folic acid blood levels were more common amongst severe patients (18.2 vs. 12.9 vs. 9.8, P = 0.014). The rate of immune compromised patients (12%) in our cohort was also higher than in the general population. The rate of deterioration from moderate to severe disease was high: 9% necessitated non-invasive oxygenation and 15% were intubated and mechanically ventilated. The mortality rate was 3.1%.

Conclusions: COVID-19 patients present a challenge for healthcare professionals and the whole medical system. We hope our findings will assist other providers and institutions in their care for these patients.

Background: Pancreatic injuries during nephrectomy are rare, despite the relatively close anatomic relation between the kidneys and the pancreas. The data regarding the incidence and outcome of pancreatic injuries are scarce.

Objectives: To assess the frequency and the clinical significance of pancreatic injuries during nephrectomy.

Methods: A retrospective analysis was conducted of all patients who underwent nephrectomy over a period of 30 years (1987–2016) in a large tertiary medical center. Demographic, clinical, and surgical data were collected and analyzed.

Results: A total of 1674 patients underwent nephrectomy during the study period. Of those, 553 (33%) and 294 patients (17.5%) underwent left nephrectomy and radical left nephrectomy, respectively. Among those, four patients (0.2% of the total group, 0.7% of the left nephrectomy group, and 1.36% of the radical left nephrectomy) experienced iatrogenic injuries to the pancreas. None of the injuries were recognized intraoperatively. All patients were treated with drains in an attempt to control the pancreatic leak and one patient required additional surgical interventions. Average length of stay was 65 days (range 15–190 days). Mean follow-up was 23.3 months (range 7.7–115 months).

Conclusions: Pancreatic injuries during nephrectomy are rare and carry a significant risk for postoperative morbidity.

Background: Male breast cancer (MBC) is a rare disease that is poorly understood. Treatment protocols are widely extrapolated from breast cancer in women.

Objectives: To review the experience with MBC of a single center in Israel over a period of 22 years.

Methods: This single center retrospective study evaluated all patients diagnosed with MBC over a period of 22 years (1993–2015). Data were extracted from patient medical charts and included demographics, clinical, surgical, and oncological outcomes.

Results: The study comprised 49 patients. Mean age at diagnosis was 64.1 ± 13.5 years. The majority were diagnosed at early stages (1A–2A) (54.4%), 30.6% were stage 3B mostly due to direct skin and nipple involvement, and 59.2% of the patients had node negative disease. All of the patients were diagnosed with invasive ductal carcinoma and 30.6% had concomitant ductal carcinoma in situ. Estrogen receptor (ER) status was predominantly positive and luminal B (HER2-) was the most common subtype. Of the patients, 18.4% were BRCA carriers. The majority of patients underwent mastectomy. Radiotherapy was delivered to 46.9% and hormonal therapy to 89.8%. Chemotherapy was administered to 42.9%. Overall survival was 79.6% with a median survival of 60.1 (2–178) months; 5- and 10-year survival was 93.9% and 79.6%, respectively. Progesterone receptor (PR)-negative patients had a significantly improved overall survival.

Conclusions: MBC has increasing incidence. PR-negative status was associated with better overall survival and disease-free interval. Indications to radiotherapy and hormonal therapy need standardization and will benefit from prospective randomized control trials.

Background: Prophylactic cranial irradiation (PCI) exclusion in favor of brain magnetic resonance imaging (MRI) staging and surveillance in the management of small cell lung cancer (SCLC) is controversial yet accepted by some centers. The use of MRI suggests performing stereotactic radiosurgery (SRS) treatment for limited brain metastases. Data regarding SRS efficacy in this setting is limited.

Objectives: To assess intracranial objective response rate (iORR), progression-free survival (iPFS), intracranial failure patterns, overall survival (OS) and time-to-whole-brain radiation therapy (WBRT)/death, whichever occurred first (TTWD) with SRS in SCLC.

Methods: The study comprised 10 consecutive SCLC patients with brain metastases treated with SRS and followed-up at Davidoff Cancer center between Aug 2012 and March 2019. Brain MRI images were reviewed by a neuro-radiology specialist.

Results: iORR was 57% as assessed by response assessment in neuro-oncology brain metastases. Intracranial progression developed in 8 patients. Median iPFS was 4.0 months (95% confidence interval [95%CI] 1.7–7.2). In-site, off-site and combined pattern of intracranial failure was seen in 0, 5, and 3 patients, respectively; median number of new brain lesions following SRS was 4 (range, 1–12). SRS was performed 10 additional times in 6 patients (median number of lesions irradiated per round was 1, range 1–5). WBRT was administered in 3 patients. Median TTWD was 20.9 months (95% CI, 1.9–26.8). Median OS since SRS administration was 23.2 months (95% CI, 4.2–not reached).

Conclusions: MRI surveillance with multiple rounds of SRS may serve a reasonable alternative to PCI or therapeutic WBRT in SCLC. 

Background: The effect of repeated intravenous amantadine (IVAM) in advanced Parkinsonism has not been studied in depth.

Objectives: To report the experience of our medical center with repeated IVAM infusions in patients with advanced Parkinsonism.

Methods: Thirty patients with advanced Parkinsonism of various etiologies were enrolled in an open-label retrospective study. All patients were treated with IVAM infusions in a neurological daycare center. Treatment was initiated with a loading dose of 200/400 mg per day for 5 days followed by a once-daily maintenance dose of 200/400 mg every 1 to 3 weeks. Patients and their caregivers participated in a structured interview and independently completed a clinical global impression of changes scale questionnaire on various motor and non-motor symptoms.

Results: Patient mean age was 73.3 ± 9.7 years, average disease duration was 6.2 ± 5.7 years, and mean Hoehn and Yahr score was 3.2 ± 0.84. Mean duration of the IVAM treatment was 15.1 ± 11.6 months. An improvement in general function was reported by 91% of the patients and 89% of the caregivers. Most of the patients reported improvement in tremor and rigidity, as well as in gait stability, freezing of gait, and reduced falls. The treatment was safe with few side effects.

Conclusions: Our data suggest that repeated IVAM infusions could be an effective treatment against various motor symptoms and for improvement of mobility in patients with advanced Parkinsonism. Further randomized clinical trials with a larger sample size using objective measures are warranted to validate our results.

Background: Statins and selective serotonin reuptake inhibitors (SSRIs) have beneficial effects on health outcomes in the general population. Their effect on survival in debilitated nursing home residents is unknown.

Objectives: To assess the relationships between statins, SSRIs, and survival of nursing home residents.

Methods: Baseline patient characteristics, including chronic medications, were recorded. The association of 5-year survival with different variables was analyzed. A sub-group analysis of survival was performed according to baseline treatment with statins and/or SSRIs.

Results: The study comprised 993 residents from 6 nursing homes. Of them, 285 were males (29%), 750 (75%) were fully dependent, and 243 (25%) were mobile demented. Mean age was 85 ± 7.6 years (range 65–108). After 5 years follow-up, the mortality rate was 81%. Analysis by sub-groups showed longer survival among older adults treated with only statins (hazard ratio [HR] for death 0.68, 95% confidence intervals [95%CI] 0.49–0.94) or only SSRIs (HR 0.6, 95%CI 0.45–0.81), with the longest survival among those taking both statins and SSRIs (HR 0.41, 95%CI 0.25–0.67) and shortest among residents not taking statins or SSRIs (P < 0.001). The survival benefit remained significant after adjusting for age and after conducting a multivariate analysis adjusted for sex, functional status, body mass index, mini-mental state examination, feeding status, arrhythmia, diabetes mellitus, chronic kidney disease, and hemato-oncological diagnosis.

Conclusion: Treatment with statins and/or SSRIs at baseline was associated with longer survival in debilitated nursing home residents and should not be deprived from these patients, if medically indicated. 

Background: Evaluation of low rectal anastomosis is often recommended prior to ostomy closure, but the efficacy of such evaluations is uncertain.

Objectives: To assess whether routine colonic preoperative evaluation has an effect on postoperative ileostomy closure results.

Methods: We performed a retrospective study evaluating all patients who underwent ileostomy closure over 9 years. Patient demographics, clinical, surgical details, and surgical outcomes were recorded and analyzed.

Results: The study comprised 116 patients who underwent ileostomy closure, of them 65 were male (56%) with a mean age of 61 years (range 20–91). Overall, 98 patients (84.4%) underwent colonic preoperative evaluation prior to ileostomy closure. A contrast enema was performed on 61 patients (62.2%). Abnormal preoperative results were observed in 12 patients (12.2%). The overall complication rate was 35.3% (41 patients). No differences in postoperative outcome was observed in patient gender (P = 1), age (P = 0.96), body mass index (P = 0.24), American Society of Anesthesiologists score (P = 0.21), and the Charlson Comorbidity Index score (P = 0.93). Among patients who had postoperative complications, we did not observe a difference between patients who underwent preoperative evaluation compared to those who did not (P = 0.42). No differences were observed among patients with preoperative findings interpreted as normal or abnormal (P = 1). The time difference between ileostomy creation and closure had no effect on the ileostomy closure outcome (P = 0.34).

Conclusions: Abnormal findings in preoperative colonic evaluation prior to ileostomy closure were not associated with worse postoperative outcome.
