Is antibiotic prophylaxis necessary in patients undergoing ureterolithotripsy?

Transurethral Ureterolithotripsy (TUL) is a frequently used procedure in urology departments. Many urologists perform TUL without antibiotic prophylaxis; however the use of chemoprophylaxis before TUL remains a controversial issue in urology. This study was carried out to assess the safety of omitting antibiotic prophylaxis prior to TUL. In a prospective randomized clinical trial from January 2005 to December 2007, 114 patients with ureteral stones were enrolled; Fifty seven had preoperative antibiotic prophylaxis administered before TUL and fifty seven patients underwent TUL without antibiotic prophylaxis. The rate of postoperative infectious complications (fever, positive blood culture, significant bactriuria), the length of hospital stay and overall stone free rate were compared between the two groups. There was no statistically significant difference between two groups in the operation time, length of hospital stay, postoperative bacteriuria, positive urine culture, postoperative fever and overall success rate of TUL. It appears that the incidence of infectious complications does not increase in patients undergoing TUL without antibiotic prophylaxis if they have negative pre-operative urine culture and antiseptic technique have been performed thorough the procedure.     

Clinical Inquiry. What is the best way to treat Morton's neuroma?

No single treatment has been identified in the literature. That said, a protocol of stepped care that showed good results in an uncontrolled trial seems reasonable: patient education and foot-wear or insole changes, followed by corticosteroid injections and, finally, surgery (strength of recommendation [SOR]: C, case series). Injecting sclerosing alcohol depends on the provider's access to and comfort with ultrasound, but the evidence is insufficient to recommend it routinely (SOR: C, case series).

Bipolar Disord 2012: 14: 31–40. © 2012 The Authors. Journal compilation © 2012 John Wiley & Sons A/S. Objective: The present study evaluated inhaled loxapine for the acute treatment of agitation in patients with bipolar I disorder. Methods: A Phase 3, randomized, double blind, placebo‐controlled, parallel group inpatient study was performed at 17 psychiatric research facilities. Agitated patients (N = 314) with bipolar I disorder (manic or mixed episodes) were randomized (1:1:1) to inhaled loxapine 5 mg or 10 mg, or inhaled placebo using the Staccato^® system. Following baseline assessments, patients received Dose 1 and were evaluated for 24 hours. If required, up to two additional doses of study drug and/or lorazepam rescue medication were given. The primary efficacy endpoint was change from baseline in the Positive and Negative Syndrome Scale‐Excited Component (PANSS‐EC) score two hours after Dose 1. The key secondary endpoint was the Clinical Global Impression‐Improvement score at two hours after Dose 1. Additional endpoints included the changes from baseline in the PANSS‐EC from 10 min through 24 hours after Dose 1. Safety was assessed by adverse events, vital signs, physical examinations, and laboratory tests. Results: For the primary and key secondary endpoints, both doses of inhaled loxapine significantly reduced agitation compared with placebo. Reduced agitation, as reflected in PANSS‐EC score, was evident 10 min after Dose 1 with both doses. Inhaled loxapine was well tolerated, and the most common adverse events were known effects of loxapine or minor oral effects common with inhaled medications (dysgeusia was reported in 17% of patients receiving active drug versus 6% receiving placebo). Conclusions: Inhaled loxapine provided a rapid, non‐injection, well‐tolerated acute treatment for agitation in patients with bipolar I disorder.

Subendocardial stress in pre‐eclampsia

A primigravida 26‐year‐old woman who had developed pre‐eclampsia with malignant hypertension at 30 weeks of gestation suffered acute myocardial infarction two days postpartum. Electrocardiogram demonstrated diffuse ST‐segment depression suggestive of subendocardial ischemia. Echocardiography demonstrated focal asymmetric left ventricular hypertrophy, with a characteristic “basal septal bulge”, and a left ventricular mid‐cavitary gradient of 51 mmHg. Coronary angiography revealed normal coronary arteries and vascular flow. Peripartum acute myocardial infarction is rare and portends a high mortality. However, to date, only one case of acute myocardial infarction associated with asymmetric left ventricular hypertrophy and pre‐eclampsia has been described in the literature.
