Docetaxel (Taxotere®), obtained from the European yew Taxus baccata, is a widely used chemotherapeutic agent active against a variety of solid tumors including breast, lung, ovarian, gastric, head and neck, and prostate cancers. The drug is administered intravenously on a weekly or three-weekly schedule. Its main side effects include myelosuppression, fatigue, myalgias, arthralgias, fluid retention, peripheral neuropathy, paronychia, and lacrimation [1]. Myositis, however, has rarely been reported.

We describe a breast cancer patient who developed severe acute myositis while on treatment with docetaxel.

Coronavirus disease 2019 (COVID-19), first identified in 2019, constitutes a global major public health burden. Most of morbidity and mortality is derived by the severe inflammatory reaction (cytokine release syndrome) that ensues in later stages. Baricitinib, a selective JAK inhibitor primarily used for the treatment of rheumatoid arthritis (RA) [1], was shown to reduce mortality in COVID-19 hospitalized patients in combination with remdesivir [2].

Background: APOE genotype strongly affects plasma lipid levels and risk for cardiovascular disease and cognitive decline. Studies of apo-e allelic and APOE genotype frequencies among several populations have revealed interesting ethnic variations that might affect cardiovascular morbidity and cognition deterioration.

Objectives: To evaluate apo-e allelic frequency among Israeli newborns based on known variances in apo-e allelic frequencies in different countries.

Methods: We examined 498 consecutive neonates born at Tel Aviv Sourasky Medical Center. Umbilical cord blood was sampled for genotyping and lipids. Birth weights were recorded. Demographics and parental risk factors for atherosclerosis were obtained from the mothers.

Results: Most parents were native-born Israelis. Other countries of origin of grandparents were Morocco, Russia, and Iraq. The prevalence of APOE genotypes in Israel is APOE 2/2: 1.4%, APOE 2/3: 8.2%, APOE 3/3: 77.7%, and APOE 4/4: 11.8%. There were no associations of APOE genotype with parental country of origin. However, there was a tendency for APOE 3/4 to be more frequent in newborns of parents of Asian and African origin. Genotype 3/3 was more frequent in newborns whose parents came from Europe and America (78%) compared to those from Asia or Africa (69%).

Conclusions: It is important to determine risk factors such as APOE genotype for evaluation of premature atherosclerosis. Determining genetic and environmental risk factors may facilitate earlier treatment and prevent heart and brain atherosclerosis. APOE genotypes did not appear to affect total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, or triglyceride levels in newborns.

Background: Acute mesenteric ischemia (AMI) is a medical condition with high levels of morbidity and mortality. However, most patients suspected of AMI will eventually have a different diagnosis. Nevertheless, these patients have a high risk for co-morbidities.

Objectives: To analyze patients with suspected AMI with an alternative final diagnosis, and to evaluate a machine learning algorithm for prognosis prediction in this population.

Methods: In a retrospective search, we retrieved patient charts of those who underwent computed tomography angiography (CTA) for suspected AMI between January 2012 and December 2015. Non-AMI patients were defined as patients with negative CTA and a final clinical diagnosis other than AMI. Correlation of past medical history, laboratory values, and mortality rates were evaluated. We evaluated gradient boosting (XGBoost) model for mortality prediction.

Results: The non-AMI group comprised 325 patients. The two most common groups of diseases included gastrointestinal (33%) and biliary-pancreatic diseases (27%). Mortality rate was 24.6% for the entire cohort. Medical history of chronic kidney disease (CKD) had higher risk for mortality (odds ratio 2.2). Laboratory studies revealed that lactate dehydrogenase (LDH) had the highest diagnostic ability for predicting mortality in the entire cohort (AUC 0.70). The gradient boosting model showed an area under the curve of 0.82 for predicting mortality.

Conclusions: Patients with suspected AMI with an alternative final diagnosis showed a 25% mortality rate. A past medical history of CKD and elevated LDH were associated with increased mortality. Non-linear machine learning algorithms can augment single variable inputs for predicting mortality.

Background: Vaginal hysterectomy (VH) and colpocleisis are both used for the treatment of advanced pelvic organ prolapse (POP).

Objective: To compare short- and long-term outcomes of vaginal hysterectomy vs. colpocleisis for advanced POP.

Methods: Hospital and outpatient charts of patients who underwent VH or colpocleisis at our institution between January 2006 and December 2015 were reviewed. Clinical data were obtained and analyzed.

Results: In this study, 188 patients underwent VH and 32 patients underwent colpocleisis. The colpocleisis group was significantly older than the VH group (79.5 ± 4.5 vs. 69 ± 6.1 years respectively, P < 0.0001) and presented with significantly higher co-morbidity rates and a higher degree of POP. Perioperative blood loss was significantly lower (250 ± 7.6 ml vs. 300 ± 115 ml, P < 0.0001) and postoperative hospitalization was significantly shorter (2 ± 2.7 vs. 3 ± 2.2 days, P = 0.015) among the colpocleisis group. None of the patients from the colpocleisis group required an indwelling urethral catheter after discharge, compared to 27.5% of the patients from the VH group (P = 0.001). Total postoperative complication rate was significantly lower among the colpocleisis group (25% vs. 31% P < 0.0001). Objective recurrence of POP was significantly more common among the VH group (7% vs. 0% and 21% vs. 0% for the anterior and posterior compartments, respectively, P = 0.04).

Conclusions: Colpocleisis is associated with faster recovery, lower perioperative morbidity, and higher success rates than VH and should be considered for frail and elderly patients.

Endovascularly retrieved clots may be a potential resource for diagnosing stroke etiology. This method may influence secondary prevention treatment. We measure thrombin activity eluted by serially washing clots. We concluded that an assay measuring the change in thrombin in clots retrieved during acute stroke endovascular thrombectomy procedures may serve as a diagnostic marker of the origin of the clot. The suggested mechanism for these differences may be the clot location before its retrieval, with high blood flow causing thrombin washout in atherosclerotic clots, in contrast to atrium appendage low blood flow retaining high thrombin levels.

Internal medicine is no doubt one of the main pillars of modern medicine. For years it has been considered to be the basis and foundation of medical education and proper clinical service. During the recent coronavirus disease 2019 (COVID-19) pandemic, internal medicine departments were recognized worldwide, and clearly in Israel, to be the true Corona Warriors that provided medical care to patients as well as support and comfort to families. Around the globe, the public applauded and appreciated the bravery of our medical staff, who without hesitation and under direct personal danger provided the best medical care possible despite the hardships of the time. The high personal price and even the heavy cost of staff member lives lost in offering medical care to the pubic did not stop our quest for ongoing medical research.

The ongoing coronavirus disease 2019 (COVID-19) pandemic has led to more than 200 million infected cases and 4.6 million deaths worldwide, and the numbers continue to grow. The disease presentation varies, and while most patients will present with a mild disease course, 5% will eventually develop significant respiratory failure, some despite initially presenting with mild symptoms. Early detection of patients at risk for deterioration is crucial for decisions regarding hospitalization, monitoring, timing, and extent of treatment.

The coronavirus disease 2019 (COVID-19) pandemic has had a profound impact on our world and has cost millions their lives. It has disrupted economies and education systems and has taken away means of support from masses of people around the world. No wonder this pandemic is like a black hole, drawing in all resources and all expertise. In the scientific arena, the pandemic has created a tremendous opportunity for new and exciting synergies between different disciplines.

Background: Most dyspneic patients in internal medicine departments have co-morbidities that interfere with the clinical diagnosis. The role of brain natriuretic peptide (BNP) levels is well-established in the acute setting but not in hospitalized patients.

Objectives: To evaluate the additive value of BNP tests in patients with dyspnea admitted to medical wards who did not respond to initial treatment.

Methods: We searched the records of patients who were hospitalized in the department of internal medicine D at Sheba Medical Center during 2012 and were tested for BNP in the ward. Data collected included co-morbidity, medical treatments, diagnosis at presentation and discharge, lab results including BNP, re-hospitalization, and mortality at one year following hospitalization.

Results: BNP results were found for 169 patients. BNP was taken 1.7 ± 2.7 days after hospitalization. According to BNP levels, dividing the patients into tertiles revealed three equally distributed groups with a distinctive character. The higher tertile was associated with higher rates of cardiac co-morbidities, including heart failure, but not chronic obstructive pulmonary disease. Higher BNP levels were related to one-year re-hospitalization and mortality. In addition, higher BNP levels were associated with higher rates of in-admission diagnosis change.

Conclusions: BNP levels during hospitalization in internal medicine wards are significantly related to cardiac illness, the existence of heart failure, and patient prognosis. Thus, BNP can be a useful tool in managing dyspneic patients in this setting.

Backgrounds: Behçet's disease (BD) is a chronic vasculitic multi-systemic disease of unknown etiology. BD is characterized by recurrent attacks of oral aphthae, genital ulcers, and uveitis. BD is a multisystemic disorder and as such it may provoke various psychiatric manifestations, including depression.

Objectives: To evaluate the association between BD and depression, adjusting for established risk factors for depression.

Methods: We executed a cross-sectional study based on the Clalit Health Services database, the largest healthcare organization in Israel, serving over 4.4 million members. For this study 873 BD patients were detected and matched with 4369 controls by age and sex.

Results: The rate of depression was higher among the BD patients compared with the control group (9.39% vs 5.49%, respectively, odds ratio [OR] 1.79, 95% confidence interval [95%CI] 1.37–2.31, P < 0.001). An association between BD and depression was also observed on multivariable analysis (OR 1.83, 95%CI 1.39–2.39, P < 0.001). When stratifying the data, according to established risk factors, the association between BD and depression was prominent in the youngest age group (18–39 years of age), low and high socioeconomical status, and non-smokers.

Conclusions: Establishing the association between BD and depression should influence the attitude and the treatment of BD patients, as this relationship requires a more holistic approach and a multidisciplinary treatment regimen for all patient needs.

Background: Patients with systemic sclerosis (SSc) are at increased risk for autoimmune thyroid diseases, but information regarding thyroid nodules and cancer in SSc is scarce.

Objectives: To evaluate the thyroid gland in patients with SSc at a single Israeli center.

Methods: Thyroid workup was conducted in consecutive SSc patients: thyroid-stimulating hormone (TSH), free thyroxine (fT4), anti-thyroid peroxidase, and anti-thyroglobulin antibodies, as well as thyroid ultrasound and fine needle aspiration (FNA) when appropriate.

Results: Fifty patients, mean age 51.3 ± 13.5 years (44 women) were evaluated. Ten were previously diagnosed with thyroid disease. Median TSH level was 2.0 (normal range 0.23–4 mIU/l) and median fT4 level was 1.0 (normal range 0.8–2.0 ng/dL). Among the 40 thyroid disorder-naive patients, 3 had subclinical hypothyroidism and 5 had positive anti-thyroid antibodies; 22 (44%) had 1–6 thyroid nodules, which were ≥ 1 cm in 12 (24%). Accordingly, six patients underwent FNA, and five were diagnosed as colloid nodules and one as papillary carcinoma.

Conclusions: New cases of clinically significant autoimmune thyroid disease were not detected in our cohort of patients with SSc. Nevertheless, almost half had thyroid nodules. The clinical significance of these findings and their relation to thyroid cancer remains to be determined.

Background: Fibromyalgia syndrome (FMS) is characterized by widespread musculoskeletal pain and tenderness with associated neuropsychological symptoms such as fatigue, unrefreshing sleep, cognitive dysfunction, anxiety, and depression. Osteoporosis is defined as a reduction of bone density. Previous studies to determine an association of FMS with osteoporosis showed mixed results, partially due to small sample sizes and lack of statistical power.

Objectives: To evaluate the association of FMS with osteoporosis.

Methods: We conducted a case-control study utilizing the database from Israel’s largest health maintenance organization. FMS patients were compared to age- and sex-matched controls. Data were analyzed using chi-square and t-tests. Multivariable logistic regression models assessed the association between osteoporosis and FMS. Spearman’s rho test was used for correlation.

Results: We utilized data from 14,296 FMS patients and 71,324 age- and sex-matched controls. Spearman's rho test showed a significant correlation between FMS and osteoporosis (correlation coefficient 0.55, P < 0.001). A logistic regression for osteoporosis showed an odds ratio [OR] of 1.94 (95% confidence interval [95%CI] 1.83–2.06, P < 0.001) for FMS compared to controls and found higher body mass index to be slight protective (OR 0.926, 95%CI 0.92–0.93, P < 0.001).

Conclusions: There is a significant correlation between FMS and osteoporosis. Early detection of predisposing factors for osteoporosis in FMS patients and implementation of suitable treatments and prevention measures (such as dietary supplements, resistance or weight bearing exercise, and bone-mineral enhancing pharmacological therapy) may reduce both occurrence rate and severity of osteoporosis and its complications, such as fractures.
