Pancreatic lesions present a diagnostic challenge. Even modern imaging techniques are not sensitive enough in determining resectability of pancreatic tumors. A substantial proportion of patients therefore undergo unnecessary surgical exploration. We determined the impact of laparoscopy and laparoscopic ultrasound (LAPUS) examinations on surgical decision-making in 60 patients with pancreatic lesions.

Of 48 with solid pancreatic lesions, 22 were defined by LAPUS as having nonresectable tumors, while conventional imaging studies defined only 9 of them as such. 3 of these 9 underwent successful resections of the pancreatic mass. Surgical intervention was ruled out by LAPUS in 16 patients (33.3%) but 26 had resectable lesions of whom 25 underwent surgery. 3 of this group were found to have nonresectable tumors at surgery, a false-positive rate of 6.2%. Overall sensitivity of LAPUS in our series was 88%.

In 12 patients with cystic pancreatic lesions LAPUS contributed significantly to the preoperative decision due to clear imaging of the cystic lesion. Additional information was obtained from ultrasound guided-biopsy of the cyst wall, as well as determination of tumor-marker levels in the cystic fluid aspirate. LAPUS contributed significantly to operative management in 58%.

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.

Prevalence of hepatitis G virus (HGV) infection in the general western population ranges from 0.2-1.5%. In high-risk groups, such as patients with chronic liver disease, hematologic disorders and drug addicts, prevalence is as high as 10%-15%. Dialysis patients have increased rates of HGV infection (6%-50%).

We evaluated prevalence of HGV infection among dialysis patients, and the association between HGV infection and hepatitis C virus (HCV) infection. Serum samples were screened for HGV infection by RT-PCR. Screening for HCV infection was performed by an EIA test and confirmed by RIBA and RT-PCR for HCV. Sera were also tested for HBV markers.

The study group included all 78 hemodialysis patients and 7 of the 12 peritoneal dialysis patients in our unit during September to November 1997. 4 (5.2%) were HGV-positive but none were peritoneal dialysis patients. 1 of the 12 HCV-positives was also infected with HGV. HGV infection was not associated with duration of dialysis, number of blood transfusions or levels of transaminases.

Prevalence of HGV infection among our hemodialysis patients was low (5.2%), but higher than reported for the general population. Prevalence of HGV/HCV infection in hemodialysis patients was low and unrelated to duration of dialysis, number of blood transfusions and levels of transaminases.

We describe a very unusual case of sudden, severe worsening of congestive heart failure which was caused by ACE inhibitors. Diagnosis was made by echocardiogram showing a typical picture of dynamic, left ventricular outflow tract obstruction without left ventricular hypertrophy, which disappeared on discontinuing ACE inhibitors. This phenomenon has already been described as a complication of other drugs such as nitrates, commonly used as provocative tests for latent obstructive cardiomyopathy. To our knowledge ACE inhibihave not been described as a causative factor.

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.

Lis Maternity Hospital, Sourasky-Tel Aviv Medical Center

We evaluated the safety and efficacy of the tension-free vaginal tape procedure (TVT) in 20 consecutive women with urodynamically proven genuine stress incontinence. Mean operating time under spinal analgesia was 37.2‏13 minutes and 80% were discharged within 24 hours. There were 5 uncomplicated, intraoperative bladder perforations, but no defects in healing nor tape rejection. The objective cure rate was 95%, while the subjective rate was 100%. Although follow-up was short (9-16 months), the TVT method seems to be safe and effective for stress urinary incontinence.

Infectious Disease Unit, Bnai Zion Medical Center, and Faculty of Medicine, Technion, Haifa

7 cases of listeriosis were diagnosed here between 1988-1997 (6 in last 3 years), or 2.94/100,000 admissions. 2 elderly patients suffered from meningitis and 2 pregnant women presented with premature contractions, 1 of whom delivered a premature, infected baby. 2 other patients had fever and gastroenteritis.

Listeria monocytogenes was isolated from blood in 4, CSF in 2 and the placenta in 1. It was isolated from those with bacterial meningitis. All patients recovered. Both increased awareness for prevention and better diagnosis are essential to reduce morbidity from this unusual pathogen.

Surgery is the mainstay in the treatment of esophageal carcinoma and is effective for palliation of dysphagia. Patients unfit for surgery are difficult therapeutic problems. We evaluated photodynamic therapy for palliation of dysphagia in this condition.

Patients were given 5-aminolevulinic acid, 60 mg/kg, orally and 24 hour later gastroscopy was performed during which red light illumination (100 j/cmŽ2 for 600 seconds) was administered. This was repeated 48 hours later. The degree of dysphagia was recorded before and 14 days after treatment.

8 patients with an advanced non-resectable tumor, or who were unfit for surgery, were thus treated. 4 had squamous cell carcinoma of the mid-esophagus and 4 had adenocarcinoma of the lower esophagus. There was mild, self- limited photosensitivity in all. Liver and renal function tests and blood count were not affected by the treatment. Dysphagia was improved in all except 1 patient. A patient with early stage disease continued to eat a normal diet.

We believe that photodynamic therapy with systemic aminolevulinic acid as a photosensitizer and a non-laser light source is feasible and safe in advanced esophageal cancer. It is an effective modality for relief of dysphagia in that condition.

The new police car flashing-light device (930 Heliobe Lightbar) has recently been implicated as potentially epileptogenic. We exposed 30 epileptic patients, 30 nonepileptic patients who suffered from headache and 15 normal volunteers to this light source. All had routine EEGs with standard intermittent photic stimulation, followed by 3-minute stimulation with the Lightbar. In none were either seizures or EEG changes induced. In 1 epileptic spike-and-wave activity induced by standard photic stimulation was enhanced with the Lightbar.

We could not confirm that the Lightbar is epileptogenic.

Massive splenomegaly is defined as a spleen weighing about 10 times normal weight. We describe a 36-year-old man who had huge splenomegaly and secondary pancytopenia simulating malignant lymphoma for about 3 months. Splenectomy was necessary because of the suspicion of hematologic malignancy, especially isolated lymphoma of the spleen, and pain and mechanical abdominal disturbances.

On operation, the spleen was 25 cm long and weighed 250 g. There was florid, reactive follicular lymphoid hyperplasia. Immunohistochemical staining with CD-20(L26), CD-45Ro(UCHL), bcl-2 oncoprotein (Dakopatts), EBV (anti-EBV mol weight 60 KD, Dakopatts) was consistent with reaction to EBV infection and not with follicular lymphoma. Lack of PCR amplification using DNA extracted from paraffin-embedded splenic tissue indicated absence of a monoclonal B cell population carrying rearranged immunoglobulin genes. The lymphocytic population was proven polyclonal by the negative results of PCR for the bcl-2 gene rearrangement. EBV seroconversion from high titer antibodies of anti-EBV-VCA-IgM to negative, and from negative EBNA to positive was consistent with an apparent primary EBV infection.

We have not found on computerized search a previous report of reactive follicular splenic hyperplasia to EBV infection causing huge splenomegaly, with or without EBV-induced infectious mononucleosis.

A 3.5-year-old boy with developmental motor retardation, hypotonicity, and severe speech disturbance had alpha-amino adipic acid in his blood and very high levels in his urine. In only 20 cases has this catabolite of lysine and hydroxylysine been found in high concentrations in urine, due to enzymatic block.

The clinical features associated with alpha-amino adipic aciduria may include mental retardation, developmental and motor delay, learning difficulties, convulsions, speech problems and ataxia. 3 siblings had milder symptoms of psychomotor delay and intermediate degrees of alpha amino-adipic aciduria, suggesting that the described developmental deficits could be related to this metabolite or its derivatives.

Brucellosis is contracted from domestic animals. Poor hygiene, primitive animal breeding methods and traditional food preparation are the main contributory factors. We describe an intersectoral program for controlling brucellosis in Taibe, an Arab town in Israel, which had a particularly high incidence of the disease in 1992 and 1993.

At the beginning of 1994 the Israel Ministry of Health and the Community Pediatric Center of Taibe established a community-based program for controlling brucellosis in Taibe. It included an intensive public health education campaign and periodic examination and vaccination of animals. Physicians, veterinarians, nurses, school officials and health inspectors were recruited for this purpose. Residents' awareness of brucellosis was determined before and after the study.

After intervention, the incidence of the disease sharply declined from 176.6 and 175.0/100,000 in 1992 and 1993 respectively, to 5.7, 10.4 and 2.5/100,000 in 1994, 1995 and 1996, respectively, (odds-ratio 24.44; p<00000). Residents' awareness of brucellosis and preventive measures were significantly increased by the end of the study. We conclude that intersectoral collaboration is an important tool for controlling brucellosis.

Between 1981-1993 581 women with primary breast cancer were treated by breast conservation. Their mean age was 56‏12 years and 63% were postmenopausal and 37% pre- or perimenopausal. The median follow-up time was 56 months. 45% had pathological Stage I disease, 49% Stage II, 2.5% Stage III and 3.5% clinical Stage I-II disease. 54% of lesions were excised with good margins, 10% with close margins (<0.5 cm), 9% with microscopic residual, 3% with macroscopic residual, and in 24% margins were not reported. Adjuvant therapy, consisting of combination chemotherapy and/or hormones, was given to 69%.

Radiotherapy, usually 50 Gy tangential photon irradiation to the whole breast, was given to 564 (97%); an electron or photon "boost" to the tumor with a median dose of 17.5 Gy was given to 378 (65%). Most of those with positive nodes received 50 Gy to the lymphatic drainage system.

1 year after radiotherapy cosmetic results were rated as "good" or "excellent" in 80%, "moderate" in 17% and "poor" in 3%. The 5-year actuarial survival was 97% in Stage I and 88% in Stage II. 37 patients (6.5%) developed breast recurrence; 11 of these (2%) had simultaneous distant metastases. 5 (<1%) developed axillary or supraclavicular lymph node metastases, and 81 (14%) developed distant metastases. Most local recurrences were in those younger than 40, and in those with primary tumors >1.75 cm.

The satisfactory level of local control achieved is attributed to the high doses of radiation (up to 75 Gy) administered to those with high risk lesions.

Traditionally Hirschsprung's disease has been treated by 2-or 3-stage procedures. During the past 6 years a 1-stage Duhamel procedure without stoma has become our treatment of choice for Hirschsprung's disease in neonates and young infants. Over a 6-year period, 15 infants and children with colonic Hirschsprung's disease were treated with the 1-stage Duhamel retro-rectal pull-through procedure without a stoma, with the Lester-Martin modification. All patients had the usual short segment aganglionosis, but 1 had a long segment which included the splenic flexure.

Early complications included wound infection in 1 and minor rectal bleeding in 3. Late complications included constipation in 1 and enterocolitis in 4. Long-term functional results were very good in all those operated except for 1 with rectal achalasia.

We conclude that Hirschsprung's disease can be successfully treated with a 1-stage pull-through operation, the child usually benefitting from the shorter hospital stay and the avoidance of a colostomy.
