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.

Dept. of Prevention, Israel Society for the Prevention of Alcoholism

A study was conducted in the winter of 1996 among 2,220 Arab adolescents in northern Israel. This fourth study among Arab youth dealt with frequency of drinking and amounts of alcohol drunk during a drinking bout. Among Christian, Druze and Moslem males there were 81.72%, 49.61% and 31.93%, respectively, who drank. The figures for females were 36.75%, 11.25% and 12.78%. About 4% of Moslem males drank 5 drinks or more consecutively, daily or every 2-3 days. The need for preventive efforts in the Arab sector is stressed.

Suprascapular Nerve Entrapment in a Basketball Player

Atzmon Tsur, Radi Shahin

Rehabilitation Unit and Dept. of Neurology, Western Galilee Hospital, Nahariya

A basketball player was shown to have a suprascapular nerve lesion without any history of shoulder girdle trauma. This acute neuropathy, never previously described in basketball players, is a result of repeated micro-trauma, due to nerve traction over the coracoid notch during violent movement ("dunking" most probably). Clinically, he was unable to abduct his arm and had some difficulty in external rotation. He developed atrophy in both the supra- and the infraspinatus muscles. Nerve conduction latency to the supraspinatus muscle was 8.0 ms, and to the infraspinatus, 8.5 ms. The compound muscle action potential registered in the supraspinatus was 1.224 mV, and in the infraspinatus, 1.237 mV. After 3 weeks of inactivity, recovery was spontaneous and practically complete.

Capgras' Syndrome

We present 3 cases of Capgras' syndrome- a delusional disorder in which the patient believes that 1 (or more) of his acquaintances has been replaced by an imposter who appears as a double. 2 were schizophrenics and 1 had depression with psychotic features. This syndrome is rare in our practice, but we do not know if this is due to lack of awareness of the condition, or to the possibility that it is a culture-related syndrome. We suggest that although the syndrome has lost some of it's significance, it is still worth making the diagnosis because of the medical and psychological implications this condition carries.

A 30-year-old female achondroplastic dwarf developed a progressive gait disturbance erroneously attributed to her hydrocephalus and deformities of both legs. Her condition deteriorated into flaccid paraplegia with anal and urinary incontinence. CT revealed extreme spinal stenosis typical in achondroplasia (shallow vertebbody, short pedicles, and hypertrophy of intervertebral joints) together with disc protrusions. Wide laminectomy of the lumbar vertebrae resulted in complete amelioration of all the neurological deficits. Progressive paraplegia is a rare complication of achondroplasia; its early recognition and surgical treatment is very rewarding.

Short term results following laparoscopic Nissen fundoplication were evaluated in 31 patients with symptomatic gastroesophageal reflux. 6 were females and 26 males, and they ranged in age from 5 months to 64 years (mean: 4.9 years in 19 younger than 18 years, and 39.3 years in 12 adults). Most of the adults who complained of pain and heartburn underwent pH monitoring, endoscopy, and manometry as needed. Milk scan was the most useful diagnostic tool for the evaluation of the children, who suffered mainly from gastroesophageal-related pulmonary disease. Indications for laparoscopic operation were identical with those for conventional open Nissen fundoplication. 1 case of dysautonomia died postoperatively; the rate of complications, mostly minor, was 22.5%. 3 patients required conversion to open Nissen fundoplication due to cardiorespiratory instability secondary to pneumothorax in 2, and to esophageal perforation in the third. 5 adults developed temporary dysphagia. 3 children had only partial improvement in their pulmonary disease following the operation, while the other 15 had complete relief. The total time for the laparoscopic operation averaged 245 minutes in adults, and 228 in children. Discharge was usually on the fourth postoperative day in adults (mean: 6.0 days). Regurgitation and heartburn were cured in 10 out of 11 adults (91%). All parents of children were satisfied. Symptomatic outcomes following laparoscopic Nissen fundoplication compare favorably with those of open surgery with respect to mortality, complications, and outcome.

Should Physical Restraints be used in an Acute Geriatric Ward?

A prospective study was carried out in an acute geriatric ward to determine the incidence of the use of physical restraints, the reasons for using them and the consequences. Over a period of 8 months an independent observer documented all cases in which a restraint was used and followed them until it was removed. A questionnaire was submitted to the nurses as to why they applied the restraints. 16% of patients had some form of restraint applied, in 2/3 of them for up to half of their stay in the ward. In over 90% of those restrained, functional (Barthel) and cognitive (mini-mental) scores were between 0-5. In unrestrained patients, the functional score was 0-5 in 79% and the cognitive score 0-5 in 72%. The main reason for applying restraints, usually sheets or body binders, was to prevent the patient from falling out of, or slipping from chairs, rather than to stop them from rising out of them. Other important reasons, which overlapped, were to prevent the patient from interfering with nasogastric tubes, catheters, and IV cannulas, each in 1/3 of the group. Restraints were discarded when deterioration did not allow the patient to sit out of bed, to decrease agitation, to allow enteral or parenteral treatment, and in 12%, when there was supervision by the family. Of 33 families interviewed, none opposed application of restraints, and most left the decision to the responsible ward staff. We conclude that restraints cannot be avoided in some acutely ill, old patients with severe physical and mental dysfunction. However, ways should be sought to minimize their use, as recommended in the literature, by demanding from the staff a specific reason, signed agreement of a physician, close follow-up, and favorable environmental conditions such as suitable chairs, occupational activity, and staff cooperation in removing the restraints.

This is a descriptive, longitudinal study of 400 elderly patients admitted for stroke rehabilitation to a geriatric department dedicated to this purpose. We present the demographic, medical, and impairment and disability characteristics on admission, and the outcome of rehabilitation. Mean stay was 54 days and 2/3 became independent and returned home. Functional score on admission was the best predictor of outcome, but age and social support were also significant.

The appearance of focal pulmonary lesions in a patient with a nonpulmonary malignancy is worrisome. Apart from metastasis, the differential diagnosis includes benign conditions such as infectious and granulomatous diseases, enlarged lymph nodes, atelectasis, radiation pneumonitis, and bronchiolitis obliterans with organizing pneumonia (BOOP). CT-guided needle biopsy is not always diagnostic and may not be feasible in very small lesions. Since open lung biopsy is associated with considerable morbidity, many physicians tend to postpone tissue diagnosis for a few weeks and perform a biopsy only if repeat chest CT scans show increase in size or number of the lesions. This approach may lead to undesirable delay of appropriate treatment. We report video-assisted thoracoscopic lung biopsy in 7 patients with nonpulmonary malignancy who developed lung lesions following chemotherapy and/or radiation therapy. Histological examination proved metastatic lesions in only 2. There were no operative complications and recovery was rapid and smooth in all patients. Thoracoscopic lung biopsy is an effective, minimally invasive diagnostic tool that obviates the need for thoracotomy in these patients.

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.

Buschke-Ollendorf syndrome is a rare condition characterized by uneven sclerotic, osseous formations seen on X-ray (osteopoikilosis) and fibrous skin papules (dermatofibrosis lenticularis disseminata). We report an 82-year-old man with this syndrome. Awareness of the condition is important to avoid misdiagnosis and hazardous management designed for other disorders, such as prostatic metastases.

Hemato-oncology patients needing mechanical ventilation for acute respiratory failure (ARF) have an extremely poor prognosis, with a mortality of more than 90%. Over an 18 month-period 17 such patients were admitted to our ICU. Diagnoses included leukemia (11 cases), lymphoma (1), and status post bone marrow transplantation for leukemia, lymphoma or breast cancer (5). Of 8 whose ARF was associated with septic complications due to neutropenia following chemotherapy, 6 survived. Of 9 who developed ARF due to toxic damage to vital organs following high-dose chemotherapy, 2 survived. Those who develop ARF during chemotherapy are expected to have an increase in granulocyte count within days, and have a surprisingly good prognosis. They should be admitted to the ICU and treated aggressively. Those who develop sepsis due their primary disease and whose general condition contraindicates chemotherapy, have an extremely grave prognosis and admission to the ICU may not be warranted.

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.
