Vibrio vulnificus is a Gram-negative bacterium living in warm salty water that produces a spectrum of human disease which may progress to devastating, sometimes fatal infections in susceptible individuals. Such infections have rarely been reported in Israel. However, over the past few months we have been seeing a sharp increase in V. vulnificus infections with a common history of injury to extremities by the sharp spines of Tilapia zillii, ("amnon" or St. Peter's fish). Clinical suspicion and prompt intervention prevent the untoward consequences of misdiagnosis or delay.

A control group of 15 patients undergoing breast surgery was given general anesthesia. In 15 other patients an interpleural block with 0.4 ml/kg bupivacaine, 0.5%, was performed 20 minutes before induction of general anesthesia for pre-emptive analgesia. This was extended further by continuous administration of bupivacaine 0.25%, 0.125 ml/kg/hr by automatic infusion pump, with supplements of opiates for postoperative pain management. The combined technique was associated with significantly reduced perioperative opiate requirement with better emergence from anesthesia, fewer side effects, a prolonged pain-free period, and overall better quality of postoperative recovery.

Penetrating injuries of the eye are an important cause of unilateral visual loss. We studied a series of 82 cases of penetrating injuries treated here from 1987 through 1993. The injuries were caused by sharp objects in 66% and blunt trauma in 6%. The prognosis after a penetrating injury is greatly influenced by the nature of the injury and the extent of the initial drainage. Among factors associated with an unfavorable visual outcome were diminished preoperative visual acuity and scleral wounds with dense vitreous hemorrhage.

Several conditions, considered as inborn errors of metabolism, involve severe deficiencies in carnitine in both plasma and muscle. In the absence of evidence suggesting primary carnitine deficiency due to a biosynthetic enzymatic defect in the liver, the various diseases with carnitine deficiency are related to genetic defects in organic acid metabolism leading to blocked mitochondrial b oxidation. We describe a 4.5-year-old boy and 2 female infants with glutaric aciduria type I, isovaleric acidemia, and long-chain acid dehydrogenase deficiency, in whom severe carnitine deficiency was apparent. In all 3, long-term carnitine treatment proved to be vital and eliminated most of the symptoms.

Erythromycin is considered the drug of choice in the treatment of streptococcal pharyngitis in patients allergic to penicillin. However, in recent years several publications, especially in Finland and Italy, showed high resistance rates of S. pyogenes isolates to erythromycin and other new macrolides. To evaluate the situation in Israel, we checked the MIC of isolates from patients with tonsillitis during 1996. E-test results showed an MIC-50 of 0.23, 0.13 and 0.47 mcg/ml for erythromycin, clarithromycin and roxithromycin, respectively and a MIC-90 of 0.37, 0.23 and 0.78 mcg/ml. Only 2 isolates (2.1%) were partially or completely resistant to all 3 antibiotics. We conclude that empiric therapy with macrolides in Israel is still a viable option and can be recommended in S. pyogenes tonsillitis for patients allergic to penicillin.

Q fever is caused by the rickettsia Coxiella burnetti, an obligate intracellular bacterium acquired by inhalation of infected dust from subclinically infected animals. Q fever may be acute or chronic; the chronic form mostly presents as endocarditis. Immunocompromised states and underlying heart disease are the most important risk factors. Usually the symptoms of Q fever endocarditis are nonspecific and diagnosis is often established very late. New criteria for diagnosis include a single blood culture positive for Coxiella burnetti, positive Q fever serology and characteristic echocardiographic studies. We describe a 49-year-old man with bicuspid aortic valve admitted with fever, weight loss and a new heart murmur. The diagnosis of Q fever endocarditis was established by positive Q fever serology, and an echocardiogram showing vegetations and valvular dysfunction. This case suggests that Q fever endocarditis should be considered in patients with "sterile" endocarditis.

During 1989-1994, there were 322 episodes of Gram-negative enteric bacteremia in 308 children. The incidence increased from 31/100,000 in children younger than 15 years of age during 1989-1991, to 50/100,000 during 1992-1994. The most common pathogens were Klebsiella, E. Coli, Salmonella and Enterobacter. 39% of episodes were nosocomial and a significant increase was recorded for each species during the last 3 years of the study. Klebsiella represented the most common pathogen causing nosocomial bacteremia, while E. coli and Salmonella were the main pathogens causing community-acquired bacteremia. In this study in southern Israel, the incidence of Gram-negative enteric bacteremia was significantly higher in Bedouin children, with the exception of bacteremia due to Salmonella, which occurred mainly in Jewish children.

Advances in Ophthalmological Photodynamic Therapy

Photodynamic therapy is a new experimental therapeutic technique which is attracting increasing attention. Its biopharmacological basis of action is the specific interaction of a photosensitizing compound with the cellular elements of pathological lesions. The photosensitizer is thought to enter specifically into the pathologic cells, where it accumulates. The lesion is then irradiated with a sensitizing laser-beam of specific wave-length to activate the photosensitizer, which then becomes a generator of free oxygen radicals. These radicals destroy the sensitizer-harboring pathological cells. The advantage of specifically destroying pathological lesions without affecting surrounding normal tissue is obvious. Recently, many experimental studies have been conducted to test the usefulness of photodynamic therapy for ocular disorders, mainly advanced age-related macular degeneration and uveal melanoma. Results so far are encouraging.

Acute infectious diseases of the gastrointestinal tract and food poisoning are problems of great importance in the Israel Defense Force (IDF). They involve individual and epidemic morbidity, with impairment of health of individual soldiers and in the activities of units. Outbreaks of gastrointestinal infectious diseases must be reported to the IDF army health branch, which conducts epidemiological investigation. This study is based on data from yearly epidemiological reports for 1978-1989, and from a computerized database for the years 1990-1995. The incidence of outbreaks is characterized by an unstable trend, It was highest at the end of the 80's (68.3 per 100,000 soldiers on active duty) and lowest for the last 2 years (1994-1995, 36.3 per 100,000). The incidence of soldiers involved in food-borne outbreaks has been more stable, constantly declining during the course of the years. There was marked seasonality with a peak in the summer months. Sporadic morbidity was constant in 1990-1995, with a yearly attack rate of 60% in soldiers on active duty. Shigella strains were the leading cause of outbreaks until 1993, while in 1994-1995 their proportion decreased, with an increase in the proportion of Salmonella strains. As to Staphylococcus aureus, its role in causing food poisoning has been characterized by marked changes. Shigella sonnei replaced Shigella flexneri as the leading strain. 73.3% of outbreaks were small, with fewer than 40 soldiers involved, while 5.4% of outbreaks affected more than 100 soldiers. Outbreaks in which a bacterial agent was identified or which occurred in new-recruit bases were larger than those in which a bacterial agent was not identified, or which occurred in active field unit bases. In conclusion, the rates of infectious disease of the gastrointestinal tract are still high, although there has been a marked decrease since 1994. The incidence of outbreaks has also decreased, as well as the role of Shigella as a leading causative agent.

To study the effect of stroke on the quality of life in younger adults, 199 patients 17-49 years of age who had sustained a first stroke between 1.11.92 and 31.10.93 were followed up. They were interviewed by telephone at 3, 6, 12 and 24 months after the event. 2 died during the first year of follow-up, and 8 had recurrent strokes. After 2 years, 8 additional patients had died and 4 had sustained recurrent events. Gradual improvement was reported within all age groups and in all areas. During the 3-6 months period, a mean of 4% improvement occurred in functional capability, 15% in social and recreational activity and 8% in return-to-work. The 6-12 month period showed an increase of 3% in improvement in mean functional capability, 10% in social and recreational activity and 2% in return-to-work. 1 year after the stroke 27% remained with moderate to severe disability, but over 86% were functionally independent in their daily living activities. There were no significant changes during the second year of follow-up in these statistics. 67% of those employed prior to their stroke returned to work and approximately 70% reported a return to prestroke social and recreational activity. These results demonstrate that the relatively high recovery rate and functional improvement during a year of follow-up were not accompanied by similar rates of improvement in emplyment and in social integration. They indicate the need for increased emphasis on long-term psychosocial rehabilitation services within the community.

A series of 12 patients with 16 episodes of prosthetic heart-valve thrombosis over 3 years is presented. Most episodes affected mitral or tricuspid bileaflet prostheses. All patients were inadequately anticoagulated at the time of thrombosis. The clinical presentation was acute and severe in 6 patients, and subacute or chronic in the rest. Physical examination was suggestive of stuck valves in most cases. Transthoracic echocardiography revealed increased transvalvular gradients in most. However, clearer evidence of valve thrombosis was obtained from transesophageal echocardiography or fluoroscopy. 9 patients eventually had their valves re-replaced successfully, and the preoperative diagnosis was confirmed in all. 5 patients were operated as soon as the diagnosis was established, and an additional 4 were operated after failure of anticoagulation. In 4 patients the valve leaflets became completely mobile after a course of thrombolysis. Prosthetic valve thrombosis is a severe and potentially fatal complication in patients with mechanical heart valves. Alertness of physicians at all levels- the general practitioner, the internist and the cardiologist- to the possibility of valve thrombosis and to its clinical presentation may lead to prompt and earlier diagnosis and to comprehensive therapy.

Budd Chiari syndrome is a rare disorder resulting from occlusion of hepatic venous drainage by hepatic vein thrombosis or by a membranous web in the inferior vena cava. In western countries the commonest causes are myeloproliferative disorders and hypercoagulable states. Presentation may be acute with rapid accumulation of ascites and hepatic failure, or subacute with symptoms developing over a few months. A chronic progressive form has also been described. On presentation there is usually abdominal pain, ascites, and hepatosplenomegaly; hepatic encephalopathy is found in about a third. Noninvasive, ultrasound-Doppler is recommended in diagnosis, and has a high correlation with hepatic venography. Liver biopsy is required for therapeutic decisions. Those with advanced hepatic failure or severe fibrosis on liver biopsy are referred for hepatic transplantation. When biopsy shows only hepatic congestion and inflammatory infiltrates, portosystemic shunting is recommended. We present a 61-year-old woman with ascites and hepatosplenomegaly that had developed over the courses of a few months. Budd-Chiari syndrome with chronic myelofibrosis and congenital protein C deficiency were diagnosed. Portosystemic shunt was performed but death from sepsis followed shortly.

Radical prostatectomy may cure most patients in whom the malignant tumor has not invaded through the prostatic capsule. Advances in surgical technique and accumulation of experience have decreased the complication rate significantly. Long-term results of surgical treatment are now better than those of other forms of treatment; hence radical prostatectomy is now recommended for men with life expectancies longer than 10 years. Between 1988 and 1995, 164 men with clinical stages T1 or T2 adenocarcinoma were admitted for radical prostatectomy. Most were not offered a nerve-sparing procedure, so as to allow wider, more complete resection. Those who wanted preservation of sexual function underwent the nerve- preserving procedure. In 6 patients operation was discontinued when metastases to the iliac lymph nodes were detected and in 1 when invasion of the pelvic wall was found. 157 underwent radical prostatectomy. Preoperative biopsy revealed a low-grade lesion (Gleason 2-4) in 19.1%, intermediate grade (Gleason 5-6) in 61.8% and high-grade (Gleason 7-9) in 19.1%; however, pathologic grading revealed that only 7.0% had grade 2-4 tumor, 60.5% grade 5-6 and 32.5% grade 7-9. Pathologic staging revealed T2 tumor in 58%, T3 in 38.8% (including microscopic invasion of the capsule or seminal vesicles); microscopic lymph node metastases were found in 3.2%. Tumor invasion through the capsule was found in only 2 of 13 treated with neoadjuvant androgen blockade, compared with 40% in those who did not receive this treatment. There was no operative mortality and only 14.7% has complications. All had urinary incontinence immediately after operation, but regained continence after an average of 4-5 months. 24 were incontinent for more than 12 months, but most of them had only mild stress incontinence. Most patients were impotent after the procedure. There was tumor recurrence, diagnosed by rise in serum PSA, in 26 during an average follow-up of 26.4 months (range 3-93). Cure rate of prostatic cancer by radical prostatectomy may be increased by improved preoperative staging methods and better patient selection; long term follow up is required for determining cure rate.

A benign epidural lesion in the thoracic spine is rare, and usually the result of intervertebral disc herniation or infection. Not long ago patients were diagnosed late in the course of their disease and the surgical results of the standard laminectomy usually performed were grave. The development of newer imaging techniques (CT and MRI) has made diagnosis much easier, so diagnosis is often earlier, when neurological deficit is minimal. Newer neurosurgical techniques and approaches to the thoracic spoine have been developed to treat these lesions, which we describe. Clinical data on 16 patients operated from January 1996 to January 1997 are presented.

Although first-line therapy for bronchial asthma has changed over the past decade to anti-inflammatory medication such as inhaled corticosteroids and cromolyn with possible addition of beta-agonists, theophylline is still useful and therefor widely used. However, several studies have raised serious questions regarding its efficacy in acute asthmatic exacerbations. These studies, the narrow therapeutic range of the drug, the frequency of side effects and interactions with common drugs, and individual variation in clearance and metabolism, have prompted its reevaluation in the management of asthma. Therapeutic serum levels of theophylline are between 10 to 20 mcg/ml. Most adults achieve these concentrations with daily slow-release oral theophylline preparations, 200-400 mg (approximately 10 mg/Kg) twice a day. However, when such a patient presents to the emergency room (ER) in an asthmatic attack, immediate intravenous theophylline is often given, regardless of maintenance treatment. Since the rationale for this common therapeutic approach has been challenged, the current study was undertaken. Serum theophylline levels were measured in 23 consecutive asthmatics presenting to the ER in an acute attack. 15 (68%) had therapeutic levels (above 10 mcg/ml) and 2 had toxic levels (above 20 mcg/ml), prior to receiving the standard intravenous theophylline dose given for an attack. These data indicate that most patients with bronchial asthma on oral maintenance theophylline do not require additional intravenous theophylline when in an attack. It probably will not benefit them and may even induce serious theophylline toxicity.
