The effectiveness of sequential chemo-radiotherapy in preserving the larynx in advanced laryngeal carcinoma was assessed. 4 Unselected patients (19 men and 2 women, mean age 60 years) with advanced squamous cell carcinoma of the larynx (T3-4/N0-3) received induction chemotherapy consisting of 2-3 cycles of cisplatin (100 mg/m²) and 5-flourouracil (1000 mg/m²/day) as a continuous infusion on days 1-5 followed by definitive radiotherapy: 50 Gy to the whole neck, 70 Gy to the larynx and clinically involved nodes, using a combination of 6 MV photons and 9-12 MeV electrons.

19 of The 21 patients responded to combined therapy but there was no response to induction therapy in 2 (10%) and 2 did not complete therapy due to severe toxicity. At a mean follow-up of 40 months, 7 had undergone total laryngectomy (33%), for an overall 5-year laryngeal preservation rate of 66%. Reasons for total laryngectomy in 2 patients were no response and in 5 tumor recurrence.

Mean survival was 39 months (range 11-46 months); at last follow-up 17 of 21 were alive and disease-free, 11 of whom had a functional larynx (65% of survivors). 2 died due to disease progression and 1 due to a cardiovascular event. Sequential chemo-radiation allows laryngeal preservation in about 2/3 of surviving patients without compromising survival.

Infection with Echovirus 11 is mostly asymptomatic, but it may cause a wide variety of clinical diseases, from gastroenteritis to serious diseases such as meningitis and myocarditis. In small infants, especially during the first days of life, echovirus infection may appear as a sepsis-like illness, and cause disseminated intravascular coagulopathy and shock.

We present 2 infants with severe echovirus 11 infections. A 3.5-month old died within 24 hours of shock and probably myocarditis. The other, 6-days old, presented with meningitis, hepatitis and disseminated intravascular coagulopathy. It recovered after treatment with intravenous immunoglobulin.

Echovirus 11 may cause life-threatening infections in small infants. Pediatricians should be alert to the special characteristics of this disease.

The use of testicular spermatozoa for intracytoplasmic sperm injection introduced a new treatment modality for management of male infertility.

Since testicular biopsies of non-obstructive azoospermic men are not homogenous in their histological patterns, identification with certainty of focal spermatogenesis might be difficult, particularly in those with small foci of spermatogenesis. We used an immunohistochemical marker of the male germ line, an antibody generated against RBM (RNA-binding-motif), to recognize with high precision the presence of germ cells in the biopsy. Biopsies of 30 men with azoospermia, most with non-obstructive azoospermia and a few with obstruction of the vas deferens, were evaluated.

Immunohistochemical staining for RBM protein contributed to the detection and accuracy of the identification of germ cells. Furthermore, this immunohistochemical technique aided the histopathologist to focus on even small foci of spermatogenesis. Absence of the protein expression confirmed the diagnosis of Sertoli-cell-only syndrome. The results indicate that expression of RBM can be a diagnostic marker for identifying the germ cells of small concentrations of spermatogenesis. This method can enhance the accuracy of histopathological evaluation of testicular biopsies that had formerly relied mainly on hematoxylin-and-eosin staining.

We assessed the incidence of drug abuse among patients requiring psychiatric hospitalization, and characterized the population at risk. The data on drug abuse were obtained from self-reports and urine tests in 103 patients, aged 18-65, hospitalized in the Kfar Shaul Psychiatric Hospital (autumn 1998).

There was close correspondence between the self-reports and the results obtained from urine tests. 1/3 admitted to having used illegal drugs and signs of drug abuse were found in about 1/4 of the urine tests. The most prevalent drugs were cannabis products (hashish and/or marijuana) and in 15 patients opiates.

Drug users were younger than non-users. With regard to psychiatric symptomatology, fewer negative symptoms were recorded among cannabis abusers with schizophrenia, compared to schizophrenic patients with no history, past or present, of cannabis abuse.

The present findings confirm the clinical impression that there has been an increase in drug abuse among mental patients, parallel to that found in society at large. Confirmatory surveys are necessary. Our findings clearly suggest that a change in attitude has occurred in Israel to what has been considered a marginal problem. Hospitalized mentally-ill patients, the younger in particular, should be considered at risk for drug abuse.

Desynchronization of circadian rhythmicity resulting from rapid travel through at least 4 time zones leads to symptoms of jet lag syndrome. The most commonly experienced symptoms in normal individuals are sleep disorders, difficulties with concentrating, irritability, mild depression, fatigue, and gastrointestinal disturbances.

There is strong evidence relating affective disorders to circadian rhythm abnormalities, such as occur in jet lag. Less convincing suggestions relate jet lag to psychosis. We presume, relying on the literature and our accumulated experience, that in predisposed individuals jet lag may play a role in triggering exacerbation of, or de novo affective disorders, as well as, though less convincing, schizophreniform psychosis or even schizophrenia. An illustrative case vignette exemplifies the possible relationship between jet lag following eastbound flight and psychotic manifestations.

Clinical characteristics of 125 divers treated for decompression sickness (DCS) in the hyperbaric multiplace chambers of this Institute during 1992-1997 were analyzed retrospectively. In 62 (51%) the diagnosis was DCS Type I (joint pain or skin involvement) and in 60 (49%) DCS Type II (neurological, inner ear or pulmonary disease). Risk factors for the evolution of DCS were depth and duration of the dives involving accidents, violation of recommendations of the decompression tables, and repeated dives.

Results were available for 112 of the 125 patients. 54 of them (48%) recovered completely, and another 54 recovered partially; 4 did not respond to treatment. Inner ear DCS was less responsive to hyperbaric oxygen treatment (p=0.0001). There was significant improvement of neurological function in those with severe neurological injury (p=0.0001). Rapid diagnosis and transportation of divers with DCS to a hyperbaric chamber is of crucial importance.

We treated 49 patients with high energy injuries of the limbs between 1.1.94-31.12.97. They had sustained 61 fractures, 50 of which were open; 14 had bilateral injuries, and 3 had lost a limb. All fractures were stabilized on arrival with an A-O tubular external fixator. Soft tissue loss was covered by a combination of split skin graft and tissue flaps following repeated surgical debridement.

After 10 days, or when all soft tissue defects were covered, the cantilever external fixation frame was exchanged for a hybrid ring which provided three-dimensional stability and allowed early full weight bearing and joint mobilization. The hybrid ring frame did not interfere with the care of soft tissue injuries. Furthermore, it kept the risk of developing deep infections to a bare minimum. At follow-up after a median of 20 months, 1 patient had developed osteomyelitis but all had returned to independent function.

Locoregional recurrence of rectal cancer ranges between 20%-50% following apparently radical surgery. Radiation has the potential of reducing this high rate of recurrence and residual disease. A retrospective analysis of 78 patients with locally advanced, biopsy proven, adenocarcinoma of the rectum treated between 1980-1987 was conducted. 28 (36%) were treated by surgery alone (surgery); 29 (37%) by surgery and postoperative radiotherapy (post-op); and 21 (27%) by surgery and preoperative radiotherapy (pre-op). 41 were females and 37 males. The median age was 62 years (range 25-90).

All tumors were resectable. 42 patients (54%) underwent abdomino-perineal resection and 36 (46%) anterior resection patients [8 Dukes B₁ (10%); 37 B₂ (47%); 2 C₁ (3%); 31 C₂ (40%]. Local recurrences were verified by transanal or ultrasound guided needle biopsy.

The 5-year actuarial survival rates by the Kaplan-Meier method for 75 evaluated patients was 55%. Overall 5-year actuarial survival was significantly higher (p=0.001) in pre-op radiotherapy (95%) compared to surgery alone (45%), or surgery with postoperative radiotherapy (32%). The data were significant (p=0.006) for patients with stage B tumors, but not stage C. This trend of improved survival held also at 8-year follow-up (80% pre-op; 32% post-op; 27% surgery). The 5-year actuarial local control was significantly better (p=0.03) for the pre-op irradiated patients (22%), compared with surgery only (56%) and post-op radiotherapy (38%). Local control was better (p=0.02) for Dukes B tumors in the preoperative group, but not Dukes C tumors.

Actuarial 5-year survival of those without distant metastases was 87% for pre-op patients, 62% for surgery alone and 48% for post-op radiotherapy. As all patients were clinically classified as advanced rectal tumors, tumor downstaging by preoperative radiotherapy seems to be paramount for local control. Improved local control translates into a siginificant advantage in overall actuarial survival.

Hemophagocytic syndrome is a rare, fulminant disease characterized by generalized histiocytic proliferation associated with phagocytosis of erythrocytes, platelets, and to a lesser extent, of white blood cells. We report a 2-year-old boy admitted with high fever and irritability, with a rash, marked hepatomegaly and generalized lymphadenopathy. Liver function tests were abnormal and there was thrombocytopenia and hyperlipidemia. Bone marrow aspiration revealed hemophagocytosis. Despite intensive treatment with steroids, intravenous immunoglobulin and cytotoxic drugs, he died within 10 weeks.

Bronchial asthma in the pediatric age group has become prevalent recently. Many children who suffer from asthma arrive at the emergency room (ER) with exacerbations which did not respond to medical treatment at home.

Between July and December 1997, 136 children 8 months to 14 years of age (61% below 3 years), were studied in our pediatric ER. Investigation included physical examination and pulse oximetry, which were used as guidelines for scoring the children on arrival and post-treatment. Spirometry was done in those who could cooperate. For each patient a detailed questionnaire about medical and sociodemographic factors was filled.

Primary pediatricians used mainly beta-agonist and corticosteroid inhalators, while pediatric pulmonologists used mainly inhaled steroids. There was no relationship between severity of attack on arrival at the ER, mode of treatment and speed of recovery in the ER. More children treated by a general pediatrician more were admitted to hospital. Low parental education and paternal smoking were risk factors for recurrent hospital admissions.

Our results indicate that parents must be educated to stop smoking, especially those with asthmatic children, and primary pediatricians should be updated with regard to proper treatment and follow-up of asthma.

We compared severity of symptoms of chronic schizophrenics in a psychiatric hospital with those treated in its outpatient clinics.

The Positive and Negative Syndrome Scale and the Mini-Mental State examination were used to assess the schizophrenic symptoms and cognitperformance, respectively, of 25 chronic schizophrenic inpatients matched for gender, age and education with 25 chronic scoutpatients. The Global Assessment Scale and the Clinical Global Impression Scale were used to test global functioning. Assessment included psychiatric and medical history and treatment and demographic characteristics.

In-patients had significantly more positive, negative and general psychiatric symptoms. Their cognitive and general functioning were impaired. Most in-patients also had medical problems. Age of onset of schizophrenia among the in-patients was younger.

Results show a marked difference in severity of symptoms and level of functioning between chronic schizophrenic in-patients and out-patients. These differences should be considered in the planning of discharge of chronic in-patients from psychiatric hospitals into the community.

Equine Rhodococcus Equi Pneumonia: First Report in Israel and its Significance for Man

Rhodococcus equi is an important pathogen in young horses. In recent years it has been increasingly recognized as an opportunistic infectious agent in patients with immune deficiency. The increase in recognized cases may be related to the increased prevalence of AIDS. However, more cases may have been recognized lately due to increased awareness of the pathogenicity of this bacterium. Based on medical reports, there appears to be an association between Rhodococcus equi infections and exposure to animals, horses in particular.

During the past year, 2 cases of rhodococcus pneumonia were diagnosed in foals in Israel. This information deserves the attention of the local medical community because of the zoonotic potential of Rhodococcus equi and the danger of its becoming more common. The climate in Israel is conducive to its growth and viability and since it flourishes in an environment with horses, the significant growth in our equine industry in recent years may contribute to an increase in Rhodococcus infections.

There is an international epidemic of violence in the emergency department (ED) which threatens medical staff daily. The problem is underestimated in Israel and there are as yet no regulations of the Ministry of Health and the Bureau of Security and Safety that deal with the problem.

At the beginning of 1997 we conducted a retrospective survey to estimate the extent of this problem and to define its causes and the various options for management. An anony-mous questionnaire was given to all permanent workers of our ED: physicians, nurses and reception clerks, as well as physicians who worked in the ED during evening and night shifts at least twice a week.

74% of (questionnaire) responders experienced violent events, most of them 5 or more times during the previous 2 years. Violence was experienced by 90% of nurses, 70% of physicians and 64% of clerks. The main reason for violence was prolonged waiting in the ED. Other causes were dissatisfaction with treatment, refusal to leave the ED, and language that displeased the patient.

Most violent patients were middle-aged men, of whom alcohol and drug users were only a small proportion. Most victims of physical violence called hospital security personnel, but only a third of the victims of verbal violence pressed charges. Half of the staff who were physically attacked called the police and most pressed charges. Only 2 attackers were convicted; charges were dropped against 3 because of "lack of public concern." We were unable to ascertain the results of the other charges. Most victims of violence didn't press charges because of fear resulting from threats of the patient and/or family.

The violent patient was usually characterized by responders as a middle-aged man, sober, of low socioeconomic level, impatient, with a bad previous hospital experience, dissatisfied with treatment and who insisted on being admitted to hospital.

Suggestions for violence management by questionnaire- responders included 24-hour police protection and a training program in violence management for hospital security and medical staff.

The safety and efficacy of Amlodipine (AML) for mild to moderate hypertension was evaluated in a "real life" setting. This open non-comparative trial included 123 men and 143 women (age 30-91 years, mean 59.4). All had sitting diastolic blood pressure (DBP) between 95 and 115 mmHg, confirmed in most by 2 baseline measurements, 2 weeks apart.

Eligible patients were given AML 5 mg daily as add-on or monotherapy and were evaluated 4 weeks later. If DBP was then >90 mmHg, the daily dose was raised to 10 mg; those with <90 mmHg remained on 5 mg. AML was continued for 8 weeks. Other BP-lowering drugs were unchanged.

Of the original 266 patients 22 (8.2%) withdrew due to adverse events (AE), and others were protocol violators, lost to follow-up or withdrew, leaving 211 available for efficacy analysis. In this major group BP was reduced from 165±15/101±4 to 139±11/83±5 after 12 weeks of AML (p<0.05). The reduction was greater in those under 70 years, from 173±12/100±5 to 142±12/80±4 (p<0.05). In those with BMI>30 kg/m², BP decreased from 165±15/101±5 to 140±12/83±5 (p<0.05).

Mean change in heart rate was -1.5 bpm (p<0.05). Mean final AML dose was 5.5 mg/day. The most common AML-related AE requiring cessation of the drug was pedal edema in 2.6% of the 266 patients; in 3.7% it persisted during therapy. Other AE occurring in >1% were dizziness in 1.8%, headache 1.5%, flushing 1.1% and fatigue 1.1%.

We conclude that AML is an effective and well-tolerated antihypertensive suitable for most hypertensive patients.
