Background: Mass honeybee envenomation (MHE) is a rare occurrence, with possible life-threatening or fatal consequences.

Objectives: To present the first description of multiple simultaneous casualties in a single incident of MHE.

Methods: Nine young men were simultaneously attacked by a large honeybee swarm. All patients were hemodynamically stable on arrival to Sheba Medical Center. One had fiberoptic evidence of laryngeal edema. Eight (89%) of the patients had leukocytosis and laboratory evidence of rhabdomyolysis. Eight patients were hospitalized in an internal medicine ward. The patient who had the most (over 300) stings removed presented with severe rhabdomyolysis and acute renal failure (ARF) and was admitted to the intensive care unit.

Results: Most patients had a benign clinical course and were discharged within 2 days. One patient developed severe rhabdomyolysis and was treated with fluids and urine alkalinization with significant improvement. The clinical course of another patient was complicated by ARF consistent with acute tubular necrosis. His creatinine peaked at 3.04 mg/dl and improved over several days until his discharge.

Conclusions: In our case series, we demonstrated the spectrum of clinical presentations associated with MHE and highlighted the importance of stings load as a prognostic factor, which may dictate early therapeutic intervention.

Intravesicular administration of Bacillus Calmette–Guérin (BCG), a live attenuated strain of Mycobacterium bovis, has long been used as adjuvant therapy for treatment of non-muscle invasive bladder carcinoma. BCG is usually well tolerated; however, infectious complications can range from 1–5% of cases. Infectious complications of BCG [1] can be divided into localized disease, which is considered a late onset disease occurring 3 months following treatment such as cystitis, Epididymo-orchitis, and pyelonephritis. Another form is a systemic disease, which is an early onset manifestation including sepsis syndrome that usually occurs directly after treatment and is the most common form of disseminated BCG infection.

Background: Transvenous lead extraction can lead to tricuspid valve damage. 

Objectives: To assess the incidence, risk factors and clinical outcome of tricuspid regurgitation (TR) following lead extraction.

Methods: We prospectively collected data on patients who underwent lead extraction at the Sheba Medical Center prior to laser use (i.e., before 2012). Echocardiography results before and following the procedure were used to confirm TR worsening, defined as an echocardiographic increase of at least one TR grade. Various clinical and echocardiographic parameters were analyzed as risk factors for TR. Clinical and echocardiographic follow-up was conducted to assess the clinical significance outcome of extraction-induced TR.

Results: Of 152 patients who underwent lead extraction without laser before 2012, 86 (56%) (192 electrodes) had echocardiography results before and within one week following the procedure. New or worsening TR was discovered in 13 patients (15%). Use of mechanical tools and younger age at extraction were found on multivariate analysis to be factors for TR development (P = 0.04 and P = 0.03 respectively). Average follow-up was 22.25 ± 21.34 months (range 8–93). There were no significant differences in the incidence of right-sided heart failure (50% vs. 23%, P = 0.192) or hospitalizations due to heart failure exacerbations (37.5% vs. 11%, P = 0.110). No patient required tricuspid valve repair or replacement. Death rates were similar in the TR and non-TR groups (20% vs. 33%).

Conclusions: TR following lead extraction is not uncommon but does not seem to affect survival or outcomes such as need for valve surgery. Its long-term effects remain to be determined.
