A 48-year-old man presented with recurrent syncope which was preceded by facial edema and difficulty in breathing. Physical examination, laboratory tests, abdominal CT and bone scan were all within normal limits. Bone marrow biopsy was consistent with mastocytosis. Systemic mastocytosis consists of a spectrum of disorders characterized by aberrant proliferation of tissue mast cells, and are mainly related to mast cell mediator release.

Urinary bladder carcinoma with trophoblastic differentiation (TD) is a variant of urothelial (transitional cell) carcinoma (TCC) which secretes placental proteins, predominantly beta-human chorionic gonadotropin (HCG). An aggressive clinical course and a poor prognosis are characteristic of this tumor. We evaluated the frequency and clinical and pathological appearance of TCC-TD in the Upper Galilee and Golan Heights between 1988 and 1995 inclusive. Beta HCG, human placental lactogen (HPL), pregnancy specific beta-1 glycoprotein (SP-1) and placental alkaline phosphatase were determined immunohistochemically in paraffin-embedded TCC of urinary bladder. Tumor grade, stage and patient survival were also determined. There was beta-HCG immunostaining in 13 of 62 cases (20.9%). TD was correlated with higher grades of TCC and with advanced stages of disease. No cases of TCC-TD were found in grade 1, stage 0. Co-expression of beta-HCG and HPL was displayed in 2 cases, beta-HCG and SP-1 in 9, and beta-HCG, HPL and SP-1 in 2. Disease-free survival and overall survival were shorter in TCC-TD.

Learning methods chosen by residents in family medicine during their residency and the correlation between them and achievement in the written specialty exams (Stage 1) were investigated. The learning patterns studied were: structured learning (certification course, study with a tutor, staff meetings, conferences) and self-learning (textbooks, journals, the Hebrew publication "Update," and audio tapes). Of 184 residents who took the examination in 1994-5, 104 responded to a questionnaire as to preferences for the various learning aids and satisfaction with their use. There was no correlation between use of a given learning method and success in the examination. Significantly more candidates preferred self-learning, especially among those who were successful, but also among some who failed the examination. There was no direct connection between the examination and the high level requirements of the residency program, for which up-to-date, integrated knowledge based on self-learning is needed.

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.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired disorder of blood cells which originate from an abnormal hematopoietic stem cell. The condition is characterized by nocturnal hemoglobinuria, chronic hemolytic anemia, and thrombosis. We describe a 60-year-old woman with PNH admitted with abdominal pain and jaundice, who had dark urine on arising after a night's sleep. The diagnosis was established by the typical clinical story and a positive Ham test. She was successfully treated with Halotestin and folic acid. Although PNH is rare, it should be considered in the differential diagnosis of hemolytic anemia. Early diagnosis and treatment are important.

During craniotomy, the patient's cooperation is needed during procedures in which continuous neurological examination and mapping of crucial regions close to the area to be resected area are required. We report our experience in 9 patients who underwent such procedures under intravenous propofol as the main sedating agent. This short-acting hypnotic was administered prior to and during the painful stages of the procedure. Patients were fully asleep when the skull was opened and the dural flap raised or excised. During the rest of the operation patients were lightly sedated but remained responsive and cooperative. This enabled precise intra-operative mapping of the brain and surgery-related neurological deficits were avoided. Respiratory depression or hemodynamic compromise were not encountered. All patients were comfortable during the operation and there were no additional neurological deficits after operation. We believe that propofol should be the main sedating agent used for these procedures.

There are few reports contrasting the clinical characteristics of Crohn's disease in different age groups. We therefore compared retrospectively children and adults with Crohn's disease. 23 children (mean age: 12.8±2.5 years) and 66 adults (mean age: 27.0±4.0 years) were studied. Presenting symptoms of abdominal pain and diarrhea were significantly more common in adults, while in children anorexia and weight loss were more frequent. Children tended to present with extra-gastrointestinal tract symptoms as well, mainly anemia and joint involvement. Common symptoms during active disease did not differ between groups, except that weight loss, evident in all children, was found in only 70% of adults. Anemia was present during active disease in all pediatric cases but in only 62% of adults. There were no significant differences between groups regarding disease location, gastrointestinal complications and extra-intestinal manifestations. We conclude that in children Crohn's disease may differ significantly, mainly presenting with nonclassical symptoms, such as anemia and joint involvement. The primary care physician should be aware of these differences.

During 1987-1996, 39 of 720 patients hospitalized (most for severe schizophrenia) were diagnosed as having active pulmonary tuberculosis (5.4%, 975 per 105 per year). In 1992-1993, after a cluster of 5 cases was found, all patients were screened by PPD skin test and chest X-ray and 16 more cases were identified. Diagnosis was confirmed bacteriologically in only 10 of them but there were typical radiological findings in the others. 39 were treated with a multi-drug regimen. In addition, 333 exposed patients and 21% who had converted their skin tests were given isoniazid preventive therapy. A small increase in levels of liver enzymes was common, but significant abnormality (over 4 times the upper limit of normal) was found in only 7 patients, in whom therapy was therefor stopped or changed. During a follow-up period of 4 years, 2 more developed tuberculosis and 33 converted their PPD reactivity status. We conclude that an outbreak of tuberculosis in a psychiatric hospital can be controlled with a relatively low rate of side-effects by using systematic diagnostic and therapeutic measures. However, single step screening is not sufficient. Routine screening of all new patients, a high index of suspicion and contact investigation are needed.

We examined the long term results of vertical banded gastroplasty 3-10 years after operation. They were assessed by weight lost, incidence and severity of untoward effects and improvement in diet and in quality of life in 75 of 122 who had had the operation. Average weight lost was 28.5±14.9 kg (p<0.001) in 5 years and 58.6±30.4% of excess weight, which brought patients to within 32±25.2% of ideal weight. According to these measures, in 63-76% the operation had been successful in causing weight loss. The 2 criteria for successful weight loss were loss of more than 50% of weight in excess of ideal body weight and residual body weight less than 50% greater than ideal body weight. There was a greater risk of failure in unmarried subjects older than 45 (odds ratio for not losing weight was 6; in those weighing more than 120 kg it was 9). We saw evidence of this mostly 4 years after operation (odds ratio 11). The degree of success in weight loss was correlated with texture of food (softness) preferred and length of operation. Of those interviewed, only 65% were satisfied with their results. The greatest improvement in quality of life measurements was in physical activity, perception of health, and frequency of feeling depressed. Side-effects were vomiting, reflux and fatigue. Only 34.7% were able to digest solid foods, so that subjects are at risk for nutritional deficiencies.

Experience with Under-Water Birth

Eylon Lachman, Zvi Finelt

Dept. of Obstetrics and Gynecology, Yoseftal Hospital, Eilat

Underwater birth is now deemed an acceptable type of delivery. Safety is a recurring consideration, the main concern being that of drowning. But in reports of 19,000 underwater births no untoward events were noted. Also, need for pain relief and of intervention during labor were both reduced. The short term indicators of neonatal outcome were good. A recent review explains 5 different physiological factors which inhibit initiation of fetal breathing under warm water. Many studies have shown no increase in risk of infection of either mother or baby. We report our experience with 26 women, 23 of whom actually delivered in the pool with excellent results. We believe that birth under water is safe and beneficial if done properly for low-risk patients.

Six Cases of Acute Rheumatic Fever in One Year

George Habib, Ramiz Abu-Ahmad

Rheumatology Clinic and Dept. of Medicine, Nazareth Hospital; and Medical Dept. B, Carmel Medical Center, Haifa

During 1995, 6 cases of acute rheumatic fever were diagnosed here. Taking into account differences in total admissions, this appears to represent an increase over 1994. Most of the cases were males, with average age at diagnosis 19.5 years. All were of low socioeconomic status. 50% had cardiac involvement, and 1 needed treatment with corticosteroids. Most had pharyngeal symptoms prior to the acute attack, and 1 patient had 2 prior episodes of rheumatic fever. A thorough epidemiological study should be done in the Nazareth area to assess the real incidence of acute rheumatic fever, and to determine whether there is a true increase in incidence.

Verapamil-Associated Liver Injury

Majed Odeh, Arie Oliven

Medical Dept. B, Bnai-Zion Medical Center and Faculty of Medicine, The Technion, Haifa

Hepatotoxicity due to verapamil is very rare and to the best of our knowledge only 10 cases have been reported. A 54-year-old woman developed cholestatic liver injury and pruritus following treatment with sustained-release verapamil (240 mg/day) for arterial hypertension. The pruritus and all hepatic biochemical abnormalities completely resolved after withdrawal of the drug. Similar to previously reported cases, the pathogenic mechanism of verapamil-associated liver injury in our patient was, most probably, idiosyncratic. These cases emphasize the need for awareness of the possibility that verapamil may occasionally induce liver injury, sometimes severe and potentially fatal.

We evaluated the efficacy of ciprofloxacin eardrops compared to tobramycin and to a placebo in the treatment of chronic suppurative otitis media. 60 ears were randomly assigned to treatment for 3 weeks with ciprofloxacin, tobramycin or placebo eardrops. The organism most commonly isolated from the ear discharge was Pseudomonas aeruginosa. The clinical responses were 78.9% and 72.2%, respectively, in the ciprofloxacin and tobramycin groups, while it was only 41.2% in the placebo group. Treatment with ciprofloxacin eardrops seemed to be at least as efficient as treatment with tobramycin. Considering the lack of ototoxicity of ciprofloxacin, this treatment may be best for chronic otitis media.

Very-low-birth-weight premature infants are at high risk for invasive candidiasis. The most commonly involved organ is the kidney. Renal candidiasis may present as fungus-ball obstructive uropathy. We describe unilateral renal obstruction secondary to fungus-ball in a premature infant. Noninvasive, systemic antibiotic treatment, including amphotericin B and fluconazole, resulted in disappearance of the finding.

Radio-frequency (RF) current has been used successfully to ablate normal human tissue. To investigate further the clinical application of this modality in tumors, we studied the potential of using RF percutaneously to destroy experimental kidney tumors. 35 outbred albino rabbits underwent direct-implantation of renal VX2 tumor during open surgery. After 21 days, ultrasonography was performed to show tumor presence and size. A shielded RF needle was designed to be inserted percutaneously through an introduction needle. An electrical insulation shield covering the RF needle was retractable, controlling the length of exposure of the RF needle inside the tissue. 22 days after tumor implantation, RF was applied via this special needle using a ZoMed International RF generator. In one group of rabbits the procedure was performed under direct vision during open surgery, while in another group treatment was percutaneous, the needle guided by palpation of the tumor. Rabbits were killed 3 days later and revealed 4-25 mm intra-tumoral RF-induced lesions. A direct relation was found between lesion size and the power and duration of RF applied (at 7.5 W, R=0.48, and P=0.32). Based on our preliminary results we can conclude that RF may have clinical applications in the near future for percutaneous local tumor control in parenchymal organs.
