Critical illness polyneuropathy developed in 8 patients aged 22-84 years in our intensive care units. This acute polyneuropathy, predominantly axonal and motor, develops in the setting of the systemic inflammatory response syndrome and multi-organ failure. It is found in about 50% of patients treated in intensive care units for more than 2 weeks. In those who survive, neurological and functional recovery is the rule.

The renin-angiotensin system is thought to play an important role in the pathophysiology of kidney disease in diabetes. Previous studies have shown a possible association between the D allele of the angiotensin converting enzyme (ACE) gene, known to be associated with higher circulating levels of ACE, and increased risk of developing nephropathy in NIDDM. The present study investigated the distribution of ACE gene genotypes in the general population and patients with NIDDM, the association between the D allele and diabetic nephropathy, and the association between the ACE genotype and involvement of other target organs in NIDDM. The ACE genotype (insertion/deletion I/D) was determined in all subjects, subsequently divided into 3 groups based on their polymorphism (DD, DI and II). The presence of nephropathy was defined by an albumin-creatinine ratio of 30 mg/g or greater (mean of 2 first morning urine samples).

In the general population most had the D allele (DD or ID) and a minority the II genotype. There was no association between genotype and hypertension, ischemic heart disease, hyperlipidemia, and cerebrovascular or peripheral vascular disease. In diabetics the genotype distribution was not different from that in the general population. Within the diabetic group, there was no association between genotype and hypertension, hyperlipidemia, duration of diabetes, or HbA1C levels. Nephropathy, found in 81 of the 156 with NIDDM, was not associated with genotype. Diabetic nephropathy was not associated with retinopathy, neuropathy, or ischemic heart, cerebrovascular or peripheral vascular disease. We conclude that in the population sampled, there was no association between the D allele of the ACE gene and the risk of developing nephropathy in NIDDM.

Irradiation Injury of the Salivary Glands

Ionizing irradiation of the salivary glands often leads to severe histological and functional alterations. Such exposure usually occurs during radiotherapy in patients with head and neck malignancy. The consequent xerostomia, often life-long, may result from even relatively low dosage irradiation, and causes a great deal of suffering. We suggest a radiobiological mechanism for this phenomenon which has been studied extensively since first described in 1911. The suggested injurious role of redox active transition metal ions and highly destructive free radicals is discussed in relation to the ultimate radiosensitive cellular target, DNA.

Urinary tract lymphoma is usually reported when the secondarily stem is affected by widespread non-Hodgkin lymphoma. We describe an 83-year-old woman who presented with secondary lymphoma of the bladder 3 years after diagnosis when it initially infiltrated her breast. Treatment included local transurethral excision followed by chemotherapy, during which she died of disseminated disease.

We performed 75 laparoscopic cholecystectomies during July and September 1996. In 3 men and 4 women, aged 32-87 years, there was obstructive jaundice caused by choledocholithiasis. During laparoscopy in the jaundiced patients, calculi were identified by cholangioscopy and intra-operative cholangiography. They were washed into the duodenum (confirmed cholangiographically) after intravenous glucagon injections and dilation of the papilla of Vater.

Serum bilirubin and liver enzyme levels returned to normal within a few days. There was no operative or postoperative morbidity, nor any biliary-related systemic complications. Average postoperative hospitalization was 3 days.

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.

Guillain-Barre and other neurologic syndromes rarely occur as complications of viral hepatitis (A, B and C). Other neurologic syndromes have also been reported in serologically defined viral hepatitis, including mononeuritis, auditory neuritis, and seizures. Chronic hepatitis B and mononeuritis multiplex are found together in 31-54% of patients with periarteritis nodosa. The mechanisms of these associations are unknown, but may include direct cytotoxicity of the virus or immune-mediated damage. Vasculitis of the vasa nervorum plays an intermediate role, at least in some cases. We describe a 36-year-old man with acute non A-G hepatitis complicated by Guillain-Barre syndrome. The neurological manifestation resolved completely without specific therapy within 6 days, as the hepatitis resolved.

Road accidents, work accidents, or other trauma can cause impotence and are frequently followed by insurance claims. During 1990-97 we examined 230 males with such a complaint. All underwent full polysomnographic recordings in the sleep laboratory for 2 nights, during the course of which NPT (nocturnal penile tumescence) was examined with special equipment. It was assessed by an experienced technician following planned awakenings from REM sleep.

In 75 of the 230 subjects (33%), satisfactory erections were observed. In 100 (43%), who experienced at least 3 periods of REM sleep, no erections occurred. These patients were categorized as suffering from organic impotence. In the remaining 55 (24%), the results were inconclusive, with only partial erections or not enough REM sleep periods.

Since a man recognized as suffering from impotence may be awarded large monthly payments for life, these examinations, in our opinion, are an important tool to prevent unjustified claims, and can save the state unnecessary expenses.

This study was designed to assess possible diurnal fluctuations in the efficacy of thrombolysis with streptokinase. 156 consecutive patients treated with streptokinase during the period 1.1.95-1.7.96 were studied retrospectively. Success or failure of thrombolysis was determined according to the accepted clinical and angiographic criteria starting at midnight, 12 times at 2-hour intervals, then 8 times at 3-hour intervals, and then 6 times at 4-hour intervals. A definite peak for successful thrombolysis was found in the late afternoon and early evening hours. Between 16:00-20:00 PM, in 30.23% successful thrombolysis were observed, compared to 6.98% between 20:00-24:00 PM (p<0.05) and in 10.53% between 00.00-04:00 AM (p<0.05).

Multiple regression analysis showed that the independent factor with the greatest impact on successful reperfusion was the actual time until thrombolysis (p=0.037); then came the interval from pain onset to streptokinase administration (p=0.020), while age and gender had much lesser impacts (p=0.328 and 0.215, respectively), and individual risk factors even less.

These findings may have several clinical implications: dose adjustment for the time of day may be required, with larger doses needed during morning hours, or preference for primary coronary angioplasty to avoid increase in bleeding complications due to higher doses of thrombolytic agents.

Hepatitis A is one of the most frequently reported notifiable infectious diseases in Israel. The annual incidence as reported is around 70/100,000. The physician or the diagnostic laboratory notifies the district health office of the Ministry of Health.

The purpose of this research was to evaluate the sensitivity of passive surveillance of hepatitis A morbidity among adults, 18 years and over. Methods included study of notifications to the Ministry of Health or hospitalizations of cases of hepatitis A and of positive laboratory tests results (IgM) for hepatitis A. We estimated the extent of under-reporting by 2 different methods of extrapolation.

Data based on passive surveillance among the adult population, between 1.1.1993-31.12.1994, comprised less than 1/5 of the actual number of cases. Physicians notified about 6.2% of their hepatitis A patients. 5.1% of the notifications to the district health office were sent twice or more, usually both by the physicians and labs.

The official data on hepatitis A morbidity, based on passive surveillance, are considerably underestimated. Physicians and public health officials should be aware that such data may not accurately reflect the magnitude of the risk or the amount of disease that can be prevented. Efforts should be made to improve this situation.

In a joint effort of the Israel Center for Disease Control, the National Center for Influenza in the Central Virology Laboratory, together with a group of collaborating pediatricians and family physicians, a network for influenza surveillance was established in the winter of 1996-97. Nose and throat swabs were obtained from 571 patients with flu-like illness. 133 (23%) were positive for influenza virus. Both influenza A(H3N2) and B were isolated, predominantly influenza B during the beginning of the season. Both circulating strains were antigenically similar to those included in the vaccine for 1996-1997. Patients from whom influenza virus was isolated were significantly more likely to suffer from cough and myalgia in comparison with patients whose cultures were negative (p=0.02 and 0.003. respectively). Results of the first year of surveillance indicate that sentinel reporting clinics are useful for timely detection and identification of the viral strains circulating in the community, thus allowing prompt intervention in preventing the spread of influenza. Conclusions from the first year of the study were drawn and applied in the winter of 1997-1998.

23 patients (age 11-66 years) underwent video-assisted thoracoscopic biopsy for diffuse disease or peripheral nodular lesions of the lung. 12 had been previously treated for extra- pulmonary malignancy and lung biopsy was done for suspicious metastases. In all cases except 1, lesions were identified and biopsied by thoracoscopy. The postoperative course was easier and shorter as compared to thoracotomy and the mean hospital stay was only 2.5 days. Thoracoscopic lung biopsy is a safe, effective and accurate diagnostic modality for diffuse lung disease and peripheral lesions. It is associated with minimal postoperative pain and discomfort, short hospital stay, early return to normal activity, and gives good cosmetic results.

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.

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.

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.
