Stromal tumors of the GI tract are rare. In the retrospective and prospective study we investigated the relationship between tumor symptomatology, tumor grade and prognostic factors. During the period May 1993 - September 1999, 11 female and 13 male patients with a mean age of 62 (range-29-81) years were operated for primary gastrointestinal stomal tumors (GIST) in our department. Observed signs and symptoms were: GI bleeding (65%), abdominal pain (45%), abdominal mass (15%) and weakness (5%). In 4 patients tumor was an incidental finding during investigation or operation for another tumor. Tumor location (in decreasing order) was: stomach (15), small bowel (SB, 6), esophagus (1), duodenum (1) and colon (1). Preoperative biopsy or FNA were diagnostic in less than 50% of the cases. Operative procedures included wedge resection (8 patients), resection of segment of bowel (10) and extended resection (6), of diaphragm, SB, colon, bladder, kidney and liver. The mean tumor size was 7.8 (range-0.9-22) cm. Four tumors were graded as benign, 8 of indeterminate malignant potential and 12 malignant.

Conclusion: The main presentation of GIST is acute GI bleeding. Endoscopy is most effective for studying proximal tumors, and CT should be used to identify distal GI tract tumors. Tumor size or malignancy were not necessarily predictive of GI bleeding. When invasive to adjacent organs is present, wide excision should be contemplated as long-term survival can be achieved.

In Vitro Interferon-Gamma Release in Diagnosis of Cutaneous Adverse Drug Reactions

Diagnosis of cutaneous adverse drug reactions is an accepted terminology. Is a challenge. Drug-specific T-cell clones (CD4+ or CD8+), with a Th1- or a Th2-type cytokine-release pattern, may be generated from the peripheral blood in CADRs. In vitro drug-induced cytokine-release suggests a drug-specific immune response, and may implicate the drug as a possible inducer of the skin reaction.

We evaluated the diagnostic role of in vitro drug-induced interferon-gamma (IFN-γ) release from peripheral blood lymphocytes in patients with CADRs. We studied 22 patients with CADRs following intake of 45 drugs (1-4 drugs per patient). Drugs were classified into 3 categories of suspicion. 17 patients who took 39 drugs of the same type (1-4 drugs per patient) without developing adverse reactions, served as controls. In vitro drug-induced release of IFN-γ from peripheral blood lymphocytes, following in vitro challenge with the unmodified drugs, was evaluated.

The mean IFN-γ increase following 45 drug tests (60.8±85.2%) was higher (p<0.05) than in controls after 39 drug tests (30.1±27.7%). Significance was greater (p<0.005) when the mean IFN-γ increase for the 24 highly suspected drugs (75.1±93.4%) and that for the controls were compared.

This study suggests that the in vitro drug-induced IFN-γ release test may serve as a diagnostic tool in CADRs.

"Sharap" is a private medical service integrated within our public clinic and hospital services. Clients may choose their physician by paying a fee in addition to what their health insurance agency (Kupat Holim) pays for. All other hospital services are supplied to all patients alike. The main purpose of this study was to evaluate the extent to which this declared policy is maintained in practice.

During 5 months in 1997, 198 Sharap patients and 198 regular patients were interviewed in the the general surgery, cardiac surgery, ENT, cardiology, newborn and gynecology wards of this hospital. Both groups were similar in regard to cause of hospitalization, gender, age group (10-year age ranges), and length of hospitalization (at least 24 hours).

Similar levels of satisfaction with hospitalization in general and with the nursing service and with supportive services were found in both groups. However, Sharap patients were more satisfied with their physicians than regular patients (87% vs 74%, respectively). Similar results were also found using indirect measures of satisfaction. About 86% in both groups reported having achieved the goal of improvement in health. A high proportion of respondents from both groups (82% and 88%, respectively) could not distinguish between Sharap and regular patients in the ward. However, a greater proportion of regular patients (35% vs 21%) wanted more extensive explanations from their physicians regarding their treatment.

Sharap patients belonged to higher socio-economic classes than regular patients. Our evaluation indicates that although the Sharap service enables the affluent to choose their preferred physician, resulting in a different doctor-patient relationship, the service does not create a significant feeling of discrimination among hospitalized patients, and does not interfere with the high level of health services available to the public at large.

Benign Intracranial Hypertension following Minocyclin

A 15-year-old girl, who had been treated with minocyclin for acne for 2 months, was admitted for investigation of headache, nausea and papilledema. A space-occupying lesion was ruled out by computerized brain tomography. The diagnosis of benign intracranial pressure (pseudo-tumor cerebri) was made because of elevated cerebrospinal fluid pressure with normal biochemistry and cytology. Tetracyclines, especially minocyclin, commonly used for treating acne in adolescents, can cause benign intracranial pressure.

Splenic cysts are rarely found or diagnosed. Excluding cases of trauma, the events preceding their development have not been fully understood. We describe a 22-year-old woman in her 34th week of pregnancy in whom ultrasound revealed a cystic lesion 8610 cm. in diameter in the left upper abdomen. Further imaging tests followed by laparotomy confirmed the splenic origin of the cyst. Splenectomy was performed and the lesion was histopathologically defined as an epidermoid cyst.
