A case of disseminated coccidioidomycosis--autopsy report.

Disseminated coccidioidomycosis is a systemic fungal infection that is occurring more commonly and causes high mortality in patients with compromised host defense or debilitated. It is endemic in certain areas of North, Central, and South America. Increasingly, cases are being recognized outside the endemic area, due to travelers who have visited an endemic area. We experienced a case of disseminated coccidioidomycosis, as a reactivation of infection acquired earlier in a patient, who was a former resident of an endemic area.

Bacteremia with nontyphi Salmonella and therapeutic implication.

OBJECTIVES: The recent decades witnessed the increased incidence of bacteremia with nontyphi Salmonella, especially in patients with underlying diseases. To evaluate clinically the patients with bacteremia by nontyphi Salmonella, we investigated the clinical records of the patients. METHODS: Retrospective study was performed on 30 cases of bacteremia with nontyphi Salmonella admitted to Soon Chun Hyang University Hospital from 1987 to 1993, and we analyzed with regard to age distribution, underlying diseases, clinical presentation and fatality. RESULTS: Children below 2 years of age were seven patients and patients over 55 years of age were 8 patients. The male to female ratio was 3:2. Only five cases were nosocomially acquired. More than two-thirds (21 patients) had no discernible other illness at the time of their bacteremia. A quarter of the patients presented without gastrointestinal manifestation. There were four deaths in the 30 patients with nontyphi Salmonella septicemia (13.3%). CONCLUSIONS: We investigated the clinical characteristics of 30 cases of non-typhi Salmonella bacteremia, which has a relatively high incidence nowadays while, to the contrary, Salmonella typhi trends toward being on the decrease in Korea.

Design features and surgical use of a cannulated extrusion needle.

A cannulated extrusion needle was designed as a modification of the standard 20-gauge extrusion by including an inner 24-gauge flexible cannula that can be extended up to 18 mm beyond the metal tip. Indications for use of the instrument are reviewed along with selected case histories demonstrating its use. The instrument is used primarily for internal subretinal fluid drainage in eyes with complex retinal detachments caused by proliferative vitreoretinopathy. The flexible cannula is guided into the subretinal space through an open peripheral retinal break and the subretinal fluid is evacuated during a simultaneous fluid/air exchange. The positive pressure of the automated air pump creates a pressure gradient sufficient to achieve passive egress of subretinal fluid through the cannula. Active suction is avoided because of the risk of posterior retinal incarceration into the cannula tip. In addition, the cannula can be used to remove hemorrhage, gas, or silicone oil in the subretinal space.

Applications of a cannulated extrusion needle during vitreoretinal microsurgery.

A specially designed cannulated extrusion needle facilitates the internal drainage of subretinal fluid during vitreoretinal microsurgery. Case histories demonstrate the use of this instrument in the management of complex retinal detachments including eyes with preretinal and subretinal hemorrhage, proliferative vitreoretinopathy with open peripheral retinal breaks, retinal detachment with giant retinal tear, and combined traction-rhegmatogenous detachments due to diabetic retinopathy. This method of internal drainage appears to have specific advantages over standard techniques by allowing the removal of subretinal hemorrhage, the utilization of pre-existing peripheral breaks for internal drainage, and the complete reattachment of shallow posterior pole retinal detachments to allow laser endophotocoagulation.

Psychological evaluation of the child with a suspected central auditory dysfunction.

I have attempted to summarize the role of the psychologist and psychological evaluation in assessing a child with a suspected central auditory dysfunction. The reasons why a child may be referred for a psychological evaluation along with some of the exhibiting behaviors were discussed. The role of the psychological evaluation was examined. The indications for psychological evaluation in central auditory dysfunction were presented and alternative types of education were discussed.

Continuous ethanol production from concentrated wood hydrolysates in an internal membrane-filtration bioreactor.

Continuous culture for the production of ethanol from wood hydrolysate was carried out in an internal membrane-filtration bioreactor. The hydrolysate medium was sterilized at a relatively low temperature of 60 degrees C with the intention of reducing the formation of inhibitory compounds during the sterilization. The maximum ethanol concentration and productivity obtained in this study were 76.9 g/L and 16.9 g/L-h, respectively, which were much higher than those (57.2-67 g/L and 0.3-1.0 g/L-h) obtained in batch cultures using hydrolysate media sterilized at 60 degrees C. The productivity was also found to be much higher than that (6.7 g/L-h) obtained in a continuous cell retention culture using a wood hydrolysate sterilized at 121 degrees C. These results show that the internal membrane-filtration bioreactor in combination with low-temperature sterilization could be very effective for ethanol production from wood hydrolysate.
