We evaluated the pattern of motor evoked potentials elicited by single-pulse and slow-rate (1 Hz) repetitive, transcranial, magnetic stimulation (RTMS) in minor head injuries. The motor response to a single magnetic stimulus in patients with minor head injury was characterized by a significantly higher threshold than in healthy subjects. However, central and peripheral motor conduction was normal in all patients. A stable pattern of MEP throughout the RTMS session was the most prominent feature in the control group. A progressive decrease in MEP amplitude and irregular alternation of large and very small MEPs over the course of RTMS was observed in minor head injury. The higher threshold of the motor response and the abnormal patterns of MEP behavior revealed by RTMS may reflect impaired excitability and enhanced exhaustion of the motor cortex in patients with minor head injuries, which improve with time.

Nerve paralysis following the use of tourniquets, regular or pneumatic, for limb surgery is rare. We describe a 19-year-old male soldier who had tourniquets applied for 3 1/4 hours to his arm and both legs due to penetrating injuries. As a result, he suffered palsy of the radial nerve and both common peroneal nerves. Nerve palsy in such cases has not been described in the literature. It is not clear whether the cause is direct mechanical pressure on the nerve, nerve ischemia, or a combination of both.

We recommend that tourniquets should not be used continuously for more than 2 hours. If evacuation of the injured is delayed, the medical team should consider loosening tourniquets for short intervals or changing for a pressure bandage. This is providing the patient's condition is stable and bleeding does not start again on release of the tourniquet.

A boy of 20 months and a girl of 27 months who had previously undergone massive bowel resection due to congenital intestinal obstruction are described. During grad-ual reduction of total parenteral nutrition and initiation of oral feeding, both developed severe, acute metabolic acidosis, accompanied by encephalopathy and ataxia. After the laboratory identification of massive amounts of the d-Disomer of lactic acid in urine and blood, both were successfully treated with IV bicarbonate, and metronidazole to suppress the overgrowth of colonic lactobacilli responsible for the metabolic crisis.

The development of laparoscopic surgery in gynecology and general surgery has greatly advanced over the past decade, and recently has been successfully performed in pregnancy. In the English literature we found that of the 518 cases reported (mean age 32 years) the most common was for cholecystectomy (45%), followed by operations on the adnexae (34%), appendectomy (15%) and others (6%). To these we add 3 cases of cholecystectomy and 1 of an adnexal tumor. Of all the reported cases, 33% were performed in the 1st trimester, 56% in the 2nd and 11% in the 3rd.

This review demonstrates a definite trend to laparoscopy in pregnancy. It appears to be safe when performed by experienced surgeons, but further studies addressing safety of laparoscopic surgery during pregnancy are needed to reach definitive conclusions.

Laparoscopic splenectomy is effective and technically feasible for treating various hematological diseases such as idiopathic thrombocytopenic purpura (ITP), congenital sphero„cytosis, hemolytic anemia, and Hodgkin's lymphoma. An anterior approach to the vascular pedicle is usually described. However, in this approach to the splenic hilum, the dissection of the splenic artery is frequently difficult. The laparoscopic posterolateral approach involves dissection of the posterolateral attachments to the diaphragm, followed by the disection and ligation of all splenic branches near the splenic parenchyma. We used it in 9 adults and 4 children: 11 patients had ITP, 1 spherocytosis and 1 Hodgkin's lymphoma.

This procedure was completed in 13 patients, but in 2 it had to be converted to open surgery. Mean operating time was 3 hours and mean postoperative stay 3 days. Blood transfusion was not required and there were no postoperative complications.

Laparoscopic splenectomy is safe in both adults and children, and the posterolateral approach provides excellent visualization and allows control of the branches of the splenic vein and artery in the splenic hilum.

Ramsay Hunt syndrome is caused by infection of the geniculate ganglion of the seventh cranial nerve by varicella- zoster virus. A case in an 82-year-old woman is described. She presented with oral lesions, right facial palsy and an eruption and pain in her right ear. Oral examination revealed small circumscribed erosions on the right anterior two-thirds of the tongue, with loss of taste. There were also lesions on her right palate. Early diagnosis and treatment are important as immediate treatment is more likely to prevent irreversible complications affecting the facial and other cranial nerves involved.

Brucellosis Presenting as Acute Abdomen

Usually symptoms of brucellosis are nonspecific and characterized by a wide range of complaints. Although the disease in Israel is almost exclusively food borne (caused by Brucella melitensis in unpasteurized goat milk products) so the main route of infection is the gastrointestinal tract, but gastrointestinal complications are rare, and only sporadic cases of ileitis or colitis have been described.

We present a 43-year-old woman with an acute abdomen, probably due to diverticulitis. It was diagnosed only after blood cultures were positive for Brucella melitensis. We believe that its protean manifestations should be consin addition to the other bizarre presentations of this disease, important in our region.

Muir-Torre syndrome is a relatively rare cutaneous manifestation of hereditary nonpolypous colorectal cancer (HNPCC). This autosomal dominant syndrome is characterized by a combination of sebaceous gland and malignant visceral tumors. The common sites of internal malignancies are the gastrointestinal tract and urinary system. It appears in early adult life and its clinical course is relatively slow.

In some families genetic diagnosis can identify asymptomatic carriers of the mutation. All first-degree relatives, especially mutation carriers, should be referred from the age of 20 years for routine follow-up and early treatment, as it has been proven to decrease morbidity and mortality.

We present a 51-year-old man with Muir-Torre syndrome diagnosed by the presence of multiple adenomas of sebaceous glands, colonic adenoma and adenocarcinoma of the duodenum. The family history was typical for HNPCC. A mutation in the hMSH2 gene on chromosome 2p was found in the patient and in several asymptomatic family members. The aim of this report is to increase awareness of this syndrome and emphasize the importance of referring patients and their families for clinical and genetic counseling and diagnosis.

As the prevalence of tuberculosis is on the rise in western countries, we present a 79-year-old man who developed a pulmonary tuberculosis-like syndrome following immunotherapy with BCG for carcinoma of the urinary bladder. The symptoms subsided following 3-drug antitubercular treatment, and the addition of steroids following negative cultures for Mycobacterium tuberculosis. The course of this disease, named BCG-osis, is much more favorable than miliary tuberculosis, even with milder treatment. It is important to keep in mind this phenomenon now that there is increasing treatment of cancers with BCG.

The treatment of metastatic urothelial cancer is based on the combination of cisplatin, methotrexate, vinblastine and adriamycin (M-VAC). From November 1994 to May 1997 we treated 25 patients (51 men, 3 women, aged 50-77) with M-VAC. The tumor originated from the urinary bladder in 14 (56%) and the upper urinary tract in 11 (44%). Disease sites included: primary - 5 (25%), lymph nodes - 17 (68%), lungs - 10 (40%), bones - 8 (32%), pelvic mass and liver each - 4 (16%), with an overall median of 2 (1-5) sites per patient.

9 patients (38%) had complete responses and 8 (32%) had partial responses, for an overall response rate of 68% (95% CI 48.5%-85%). The median duration of response was 15.3 (1.6-29.6+) months. Median survival of responders was 19.1 (4.8-35.7+) months compared to 6.2 (0.7-11.2) for the non-responders (p<0.05). 13 (52%) of patients are alive, of whom 8 (32%) are free of disease and 5 with a single metastatic site on presentation at follow-up.

In the 118 treatment cycles we observed grade III-IV toxicity: myelosuppression 53 (45%), thrombocytopenia 4 (3%), stomatitis 8 (6.7%), diarrhea 3 (2.5%). There were 22 infectious episodes and 1 patient died of sepsis.

We achieved a high response rate with the combination M-VAC. However, only a third had long-term disease-free states and treatment was associated with excessive toxicity. Thera-peutic approaches with new agents are required to improve the response rate and toxicity.

Surgical Dept. B, Wolfson Medcial Center, Holon

We describe our experience in 54 consecutive patients who underwent laparoscopic repair of 86 inguinal hernias. Laparoscopic repair of inguinal hernia is technically feasible, does not prolong the length of the procedure nor of hospitalization and is not accompanied by increased morbidity. Although there is not yet general agreement, in our experience and that of others, it appears that laparoscopic repair will be the preferred approach to the treatment of inguinal hernia.

Intestinal transplantation, which until recently has been considered an experimental procedure, is now undergoing considerable change and becoming a standard treatment for patient with intestinal failure. The major improvement in results is due to the introduction of new immunosuppressive agents that have led to significant reduction in acute rejection. Nevertheless, reduction in severe infectious complications, which are the main cause of mortality after transplant, as well as improved techniques for early diagnosis of rejection are needed before intestinal transplantation can be widely used.

We describe our experience in post-transplant follow-up of a woman, aged 32-years, who had undergone intestinal transplantation for short bowel syndrome after extensive bowel resection.

Infection with Legionella remains an important cause of disease and death. We analyzed our laboratory data from 1993 through 1997, augmented by our 20 years of experience. The incidence of Legionella as a cause of pneumonia varied in our study from 5%-9%, with a slight increase during the winter. Isolation of these microorganisms from different water sources was higher during the summer and ranged from 7%-70%.

Special laboratory tests are necessary to diagnose the disease and monitor these bacteria in water samples. The serologic method - indirect immunofluorescent assay -- for 41 serogroups of Legionella was the main diagnostic method used. Legionella sg. 1 was the most frequent cause of the disease, with an incidence of 52% in 1993, decreasing to 15% in 1997. An increase in the incidence of seropositivity to "other Legionellae" is characteristic for our country.

No correlation was found between the incidence of isolation of a specific strain and exposure. However, it is well known that the disease is overtreated but underdiagnosed, which requires reversal. Larger studies of Legionella colonization in water supplies and in air are needed in order to establish the risk of infection. Water sources are presently under-studied, as are respiratory devices in hospitals, or they are not studied at all in Israel, such as in mist machines in supermarkets, in dental clinics, and in ships and airplanes.

Cerebellar infarction is relatively infrequent and accounts for about 2% of all strokes. Its clinical presentation and course are variable. It may resemble vestibulitis in mild cases, but the presentation may be more dramatic in other cases. Cerebellar infarction may cause life-threatening complications such as acute hydrocephalus or brain stem compression, resulting from their mass effect in the posterior fossa or extension of the infarct to the brain stem.

Clinical features alone are insufficient for the diagnosis and for follow-up of patients with cerebellar infarction. However the advent of CT and MRI and their availability enable early diagnosis of cerebellar infarction, and early recognition of the development of acute hydrocephalus or brain stem compression which require surgical decompression. The prognosis of most cases is good when treatment is appropriate.

Lately an increasing number of physicians are asked to diagnose and treat physical and mental disorders caused by alcohol abuse, a phenomena which had been quite rare in Israel until recently.

Early diagnosis and efficient treatment are essential for the management of alcohol-dependent patients. Primary care physicians and hospital personnel should be more alert to the growing numbers of alcohol abusers and to their appropriate diagnosis and treatment. This article describes and summarizes the symptoms of alcohol withdrawal in general, and alcoholic delirium in particular. Problems in diagnosis and treatment are illustrated by typical cases, pointing out early clinical warning signs and suggesting some treatment guidelines.
