Outbreak of cryptosporidiosis associated with a man-made chlorinated lake--Tarrant County, Texas, 2008.

In July 2008, clusters of laboratory-confirmed cryptosporidiosis cases and reports of gastrointestinal illness in persons who visited a lake were reported to Tarrant County Public Health. In response, epidemiologic, laboratory, and environmental health investigations were initiated. A matched case-control study determined that swallowing the lake water was associated with illness (adjusted odds ratio = 16.

Emergency portable cardiopulmonary bypass for abrupt left main occlusion during coronary angioplasty. Excellent long-term survival.

A 53-year-old man had total occlusion of the left main coronary artery with subsequent cardiac arrest during attempted angioplasty of the circumflex coronary artery. Conventional resuscitation was unsuccessful. However, emergent portable cardiopulmonary bypass support in the catheterization laboratory contributed to excellent long-term survival.

A walking blood donor program for seriously ill premature infants.

Premature infants with hyaline membrane disease and related disorders are frequently hypovolemic. Furthermore, they frequently require repeated phlebotomies for laboratory evaluation of electrolytes, pH, oxygen tension, and other parameters. Adequate care of such infants is aided by small transfusions of heparinized blood.

Thrombotic complications of umbilical artery catheters: A clinical and radiographic study.

Catheterization of the aorta via the umbilical artery provides a convenient route for monitoring arterial blood pressure, for obtaining blood specimens for measurement of blood gas tensions and chemistries, and for the infusion of fluids and pharmacologic preparations in sick newborn infants. Use of this technique may be accompanied by a number of complications of which thrombotic phenomena are the most common. Twenty-three of 98 (24%) newborn infants undergoing umbilical artery catheterization were found to have thrombotic complication determined by aortography.
