RESUMO
INTRODUCTION: Approximately a third of men worldwide and over 90% of Israeli men are circumcised. The procedure carries a low rate of complication, mainly including surgical and infectious complications. Urinary tract obstruction (UTO) is a rare complication of circumcision. AIMS: The aim of this study was to define the incidence of UTO following circumcision in the last 20 years and describe the characteristics of the affected babies. METHODS: Study participants were identified from a list consisting of all male babies aged 7-30 days treated at the Shaare Zedek Medical Center during the years 2000-2020. Files of patients with serum creatinine ≥ 1 mg/dl were reviewed. Clinical and laboratory data were collected from patients' records. RESULTS: Ten babies with acute kidney injury due to UTO after circumcision were identified. Average age at admission was 10.1 days (8-13). Only two babies had an uncomplicated postnatal course. The main findings on physical examination were distended abdomen, abdominal wall discoloration and leg edema. Average creatinine on admission was 1.76 mg/dl (1.0-3.28). Additional findings were hyperkalemia 6.2 mEq/L (4.5-7.6) and hyponatremia 125 mEq/L (118-134). All hospitalized patients developed post-obstructive diuresis. Kidney function and laboratory abnormalities completely resolved in all of our patients. There was no evidence of kidney damage in six children with long-term follow up. CONCLUSIONS: UTO with acute kidney injury is a rare severe complication of circumcision. Prompt identification and proper treatment can result in complete resolution of kidney function.

BACKGROUND: Systemic oxalosis is a severe complication seen in primary hyperoxaluria type I patients with kidney failure. Deposition of insoluble calcium oxalate crystals in multiple organs leads to significant morbidity and mortality. METHODS: We describe a retrospective cohort of 11 patients with systemic oxalosis treated at our dialysis unit from 1982 to 1998 (group 1) and 2007-2019 (group 2). Clinical and demographic data were collected from medical records. Imaging studies were only available for patients in group 2 (n = 5). RESULTS: Median age at dialysis initiation was 6.1 months (IQR 4-21.6), 64% were male. Dialysis modality was mostly peritoneal dialysis in group 1 and daily hemodialysis in group 2. Bone disease was the first manifestation of systemic oxalosis, starting with the appearance of sclerotic bands (mean 166 days, range 1-235), followed by pathological fractures in long bones (mean 200.4 days, range 173-235 days). Advanced disease was characterized by vertebral fractures with resulting kyphosis, worsening splenomegaly, and adynamic bone disease. Two patients developed pulmonary hypertension, 4 and 8 months prior to their death. Four of 11 patients developed hypothyroidism 0-60 months after dialysis initiation. Only one patient survived after a successful liver-kidney transplantation. Four patients died after liver or liver-kidney transplantation. CONCLUSIONS: This is the first comprehensive description of the natural history of pediatric systemic oxalosis. We hope that our findings will provide basis for a quantitative severity score in future, larger studies.

BACKGROUND: Initiating varenicline use 4 weeks before the target quit date (TQD) reduces smoking in the run-in phase and increases end-treatment cessation rates; however, the lack of a smoke intake plateau suggests longer preloading periods are required. This study assessed whether varenicline preloading for 6 weeks reduced pre-quit smoke intake and enhanced 6-month abstinence outcomes compared with the standard 1-week preloading. METHODS: In this randomised single-centre controlled trial, (ClinicalTrials.gov identifier: NCT02634281), conducted between February 2016 and July 2018 in Israel, daily smokers (nâ¯=â¯242) aged ≥ 18 years were randomly assigned (1:1) to receive varenicline preloading for 6 weeks (nâ¯=â¯121) or a placebo for 5 weeks followed by varenicline for 1 week (nâ¯=â¯121) before the TQD. Participants and researchers were masked to both group assignment and treatment allocation. Both groups received standard 12-week post-TQD varenicline treatment. The primary outcome was the 24-week biochemically verified continuous abstinence rate (CAR) from weeks 6 (TQD)-30. Secondary outcomes included the 23-week CAR from 1-week post-TQD (week 7) to week 30, and the 7-day point-prevalence (PP) abstinence at week 30. Other measures included pre- and post-quit rewards, smoking urges, nausea, aversion, and markers of cigarette consumption. FINDINGS: By intention-to-treat, the 24-week CAR, weeks 6-30 with extended preloading was significantly higher than with standard preloading (23·1% vs. 4·1%; risk reduction [RR]: -0·19 [95% confidence interval [CI]:-0·10-0·24]; p < 0·001). Extended preloading also showed better secondary outcomes. Extended preloading significantly decreased pre-quit rewards, urges, and smoke intake, including unsolicited smoking abstinence. Post-quit urges remained remarkably lower with extended preloading. Participants receiving extended preloading reported more nausea at week 4 (39.6% vs 11.5%) and abnormal dreams at week 6 (7.7% vs. 0%). Participants receiving standard preloading reported more constipation at week 7 (7.6% vs. 0%) and dizziness at weeks 7 (12.1% vs. 2.5%) and 12 (10.7% vs 1.4%). INTERPRETATION: Extended preloading reduced ad lib smoking, enhanced cessation rates at 3 and 6 months, and decreased pre- and post-quit rewards and smoking drive in a pattern compatible with a reinforcement-reduction mechanism. These data substantiate extending the standard pre-treatment period, and suggest that targeting pre-quit smoking sensations should be a treatment priority, although confirmatory evidence is needed from larger clinical trials. FUNDING: This study was funded by a 2013 Global Research Award for Nicotine Dependence (GRAND) supported by Pfizer, Inc. (#WI182915).
RESUMO
BACKGROUND: There are concerns about the effect of inflammatory bowel diseases (IBD) on fertility, pregnancy and pregnancy outcomes, but no long-term data on the health of offspring born to IBD mothers. The aims were to assess the short- and long-term effects of maternal IBD on the morbidity and development of their offspring. METHODS: Female IBD patients and controls completed questionnaires on their pregnancy outcome, and their offspring's short- and long-term health and development. RESULTS: IBD and control mothers (159 and 175, respectively) were recruited. Medical data of 412 IBD and 417 control offspring were recorded. IBD mothers had significantly more singleton pregnancies, their offspring's birth weight was significantly lower, and they breastfed significantly less compared to controls (P=0.028, 0.007, and <0.0001, respectively). There were significantly more congenital anomalies (mainly limb deformities) among the IBD offspring (P<0.035). Offspring born post-maternal IBD diagnosis, compared to pre-diagnosis, tended to have more neurodevelopmental problems (e.g., gross motor delay, P=0.03). IBD was significantly more prevalent in the offspring of IBD mothers, while allergies and atopic dermatitis were more frequent in offspring of control mothers. More offspring of IBD mothers taking medications during pregnancy were born preterm and had lower birth weights compared to offspring of IBD mothers not taking medications during pregnancy. Children of mothers taking steroids had the lowest birth weights, compared to those of IBD mothers taking 5ASAs or immunomodulators. CONCLUSIONS: Maternal IBD affects pregnancy and the offspring's immediate and long-term morbidity, specifically, congenital anomalies and neurodevelopmental problems.
