Parent and Clinician Views on Not Using Antibiotics for Mild Community-Acquired Pneumonia.

Objectives: Preschool-aged children with mild community-acquired pneumonia (CAP) routinely receive antibiotics even though most infections are viral. We sought to identify barriers to the implementation of a "no antibiotic" strategy for mild CAP in young children.

Methods: Qualitative study using semistructured interviews conducted in a large pediatric hospital in the United States from January 2021 to July 2021.

Psychological and immunological reactions of family members to patients undergoing bone marrow transplantation.

The authors' goal was to evaluate the impacts of patients' bone marrow transplant (BMT) on their spouse/partner's (subjects) psychological and immunological status at four key points in the course of their transplant. Subjects' (N = 24) psychological and immunological status was prospectively evaluated at four key points in the patient's BMT which included: at patients' admission to hospital and 0-, 20-, and 34-day intervals after BMT infusion. Psychological variables examined included: a) general psychological distress and negative affect; b) tendency to respond in a socially desirable manner; c) state negative affect; and d) coping style, specifically if escape-avoidance coping was used.

Methods for studying intestinal sensitivity and compliance: in vitro studies of balloons and a barostat.

The aim of this study was to compare in vitro various methods for recording intestinal sensitivity and compliance. Relationships between volume and pressure were determined in segments of penrose tubing and pig gut ("artificial intestine') using pressure increments of 2 mmHg (0-24 mmHg). We tested two direct methods of distension of the entire segments (by syringe inflation and the Mayo barostat); we also used three different balloon devices for indirect distension (a 10 cm polyethylene barostat bag, a 10 cm latex condom balloon and a 6 cm latex condom balloon).

Lupus anticoagulant masquerading as an acute abdomen with multiorgan involvement.

A 45-yr-old male patient developed acute abdominal pain, ileus, and microscopic hematuria with biochemical evidence of pancreatitis and a marked increase in liver alkaline phosphatase; CT demonstrated swelling of the pancreas, bilateral adrenal hemorrhage, and a suggestion of renal hemorrhage. ERCP was negative and renal arterial and venous blood flow normal. A coagulation profile demonstrated the presence of lupus anticoagulant, but tests for anticardiolipin antibodies and collagen vascular diseases were negative.

Visceral perception in irritable bowel syndrome. Rectal and gastric responses to distension and serotonin type 3 antagonism.

We wished to determine if visceral perception in the rectum and stomach is altered in patients with irritable bowel syndrome and to evaluate the effects on visceral sensation of 5-HT3 receptor blockade. Twelve community patients with diarrhea-predominant irritable bowel syndrome and 10 healthy controls were studied in a double-blind, randomized, placebo-controlled study. Using two barostats, the stomach and rectum were distended, with pressure increments of 4 mm Hg, from 10 to 26 mm Hg; visceral perception was measured on an ordinal scale of 0-10.
