Coronary artery bypass grafting is the treatment of choice for obstructive disease of the left main coronary artery. Its proximal location and easy accessibility make the left main artery an inviting target for percutaneous intervention, an approach contraindicated by the high associated risk. We describe 2 patients at high operative risk in whom the obstructed main coronary artery was successfully revascularized percutaneously. Coronary stenting and rotational ablation of calcified arteries are essential for successful outcome and minimize complications.

The skeletonized internal mammary artery (IMA) is longer, and its immediate spontaneous blood flow is greater than that of the pedicled IMA, thus providing increased versatility for complete, arterial myocardial revascularization without the use of saphenous vein grafts. From April 1996 to May 1997, 583 patients underwent coronary artery bypass grafting here and in 415 (71%) complete arterial revascularization was achieved using bilateral skeletonized IMA. The right gastroepiploic artery was used in 57 (13%); there were 329 males (79%) and 86 women (21%); average age was 64 (30-87) and 175 (36%) were older than 70; 131 (32%) were diabetics. Average number of grafts was 3.2 (range 2-6 grafts). At 30 days, 5 (1.2%) had died and there had been 6 perioperative infarcts (1.4%), 5 CVA's (1.2%), and 6 had sternal wound infections (1.4%). Up to 1-12 months of follow-up was achieved in 409 (99%). Late mortality was 1.4% (of which 3 were noncardiac). 394 (97%) were angina-free at latest follow-up. We conclude that arterial revascularization using bilateral skeletonized IMA is safe, as postoperative morbidity and mortality are low, even in old and diabetic patients.

Abdominal compartment syndrome refers to a complex of negative effects of intra-abdominal hypertension. Its most common cause is complicated abdominal trauma. The syndrome includes mainly hemodynamic and respiratory manifestations but may involve other systems as well. It may present as a life-threatening emergency in the multi-trauma patient. Awareness of the syndrome may enable the surgeon to take preventive measures or to diagnose it earlier and to treat it effectively. We describe a 21-year old man who developed this syndrome after multiple gunshot wounds, with severe liver injury. After 2 operations the typical manifestations of the syndrome were diagnosed. He was re-operated to release intra-abdominal hypertension and then slowly recovered.

Secondary malignancy is a well-recognized complication of radiation therapy. The risk of postirradiation sarcoma in long-term follow-up is 0.03-0.8%. We report a case of radiation-induced perisacral angiosarcoma 6 years after pelvic irradiation for sigmoid cancer in a 77-year-old man. The tumor was diagnosed postmortem and was locally advanced and metastatic. He died 6 months after onset of symptoms. This case demonstrates the importance of long-term follow-up in those given radiotherapy.

We describe a 42-year-old woman in whom bilateral fibrosarcoma of the breast was diagnosed 15 years after bilateral breast augmentation with silicone implants. 3 years prior to admission the implants were replaced and 2 years prior to admission mammography showed a nodule in the left breast which biopsy showed to be fibrosarcoma. The implants were removed from both breasts and she was given chemotherapy but later that year underwent bilateral mastectomy. Despite chemotherapy, as well as adjuvant radiotherapy, the disease progressed, with involvement of the lungs and the skin of the left hemithorax. She was admitted repeatedly for severe anemia caused by bleeding from the malignant skin lesions, and died less than 2 years after diagnosis of the disease.

Not all reports in the literature find a significant connection between silicone implants and subsequent development of breast cancer, but there are reports that do connect them. Breast fibrosarcoma is not significantly more frequent after silicone augmentation, but still there is controversy as to whether there is a connection between silicone implants and breast malignancy. In the patient we present, the prolonged exposure to silicone may have been a predisposing factor for the development of bilateral fibrosarcoma, since other known risk factors for breast cancer were denied.

Dept. of Surgery, Carmel Medical Center, Haifa

We present a patient with intra-osseous ganglion of the left scaphoid and lunate bone. These were excised and a bone graft inserted. 1 year after operation the patient was free of pain, without limitation of wrist motion. Intra-osseous ganglion of the carpal bone is not common and lunate and scaphoid intra-osseous ganglion has rarely been reported. Awareness of this condition may lead to earlier diagnosis and treatment, with satisfactory outcome.

Ecstasy is a stimulant used mainly by youngsters to get 'high.' There are few reports of acute injury of the liver due to ecstasy. We describe a 37-year-old woman who presented with the clinical picture of recurrent hepatitis following ingestion of the drug. After several months she developed liver cirrhosis shown by biopsy and CT scanning. This case emphasizes the potential danger of ecstasy. Every patient with hepatitis of unknown origin must be questioned about ingestion of the drug.

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.
