        A 10-year-old girl was admitted with a 3-day history of fever, cough, abdominal pain and vomiting. Severe neutropenia (total neutrophil count 186/mm³), a mild increase in ALT and AST, and a positive titer of IgM antibodies against parvovirus B19 were found. The neutropenia resolved and liver enzymes became normal as she recovered. We conclude that parvovirus B19 infection should be considered in the evaluation of an acute illness accompanied by severe neutropenia.

        Hypercalcemia is a common metabolic disorder, especially in the elderly. The most common etioloare hyperparathy-roidism or malignancy, most often of the lung, breast, kidney or hematological system. Because hypercalcemia is an uncommon manifestation in urinary tract epithelial tumors, especially those of the renal pelvis, we present a man aged 62 years with hypercalcemia due to renal transitional cell carcinoma.

        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.

        Neuropsychiatric Side Effects of Malarial Prophylaxis with Mefloquine

        Dept. of Psychiatry, Hadassah Hospital Ein Karem, Jerusalem

         

        There has been an increased incidence of malaria among Europeans returning from Africa and Asia. The relatively new antimalarial mefloquine (Lariam) has become extremely popular due to its efficacy in treatinthe wide-spread chloroquine-resistant Plasmodium falciparum.

         

        Mefloquine is used both for prophylaxis and treatment of malaria and is relatively well tolerated. However, since introduced in 1985, there have been over 100 reports of severe neurologic and psychiatric adverse effects associated with its use, including acute psychosis, affective disorders, acute confusional states and seizures.

         

        We describe a 39-year-old woman who developed acute psychosis after being given mefloquine prophylaxis. Adverse effects occur more often after therapeutic rather than prophylactic use, and those with a history of seizures or psychiatric illness are at increased risk of developing these reactions. Physicians should be aware of these possible side effects and prescribe mefloquine only when indicated.

        Carmel Medical Center, Haifa

         

        2 women, aged 31 and 37 years, respectively, suffered from acute febrile illness due to acute infection with human parvovirus B19. 1 also had a maculopapular rash and articular symptoms after her fever stopped, a clinical picture typical of erythema infections. The other had leukopenia and thrombocytopenia and had received dipyrone. Although acute infection with human parvovirus usually occurs in childhood, it may also occur in adults, with protean manifestations.

        Nephron-Sparing Surgery - Initial Experience with 50 Patients

        During recent years the use of the new imaging techniques, ultrasonography and computerized tomography, has increased. The accessibility to these methods has changed the pattern of detection of renal lesions. Over 90% of renal masses are now discovered incidentally, while investigating nonurological symptoms. Therefor, most lesions are discovered in their early stages.

        The gold-standard procedure for removing renal masses is radical nephrectomy, which ensures complete removal of an organ-confined lesion, but involves loss of functional tissue. This might be critical in patients with a single kidney, or reduced nephron function. There are several diseases characterized by multiple renal lesions, such as Von Hippel-Lindau and tuberous sclerosis in which radical treatment may lead to chronic dialysis in young patients.

         

        Nephron-sparing surgery was developed in order to preserve as much functional tissue as possible while removing safely any suspicious renal lesion. This new technique, not involving radical surgery, should be evaluated in cases of renal tumors for its ability to achieve the same cancer cures rates. We present our experience with our first 50 patients who underwent nephron-sparing surgery for removal of renal lesions.

        Laparoscopic Donor Nephrectomy: Initial Experience

        Advanced Endoscopic Surgery Unit, Transplantation Unit and Depts. of Surgery B-C, Tel Aviv-Sourasky Medical Center and Sackler Faculty of Medicine, Tel Aviv University

         

        We present our initial experience in laparoscopic nephrectomy. 6 patients were operated for a kidney donation and 2 for treatment of a benign disease. All procedures were completed successfully, with no conversion to laparotomy or intra-operative complications. Mean operating time was 210 minutes, and in the donor kidneys the mean warm-ischemic time was 165 seconds. There were 3 postoperative complications, and mean hospitalization was 3.5 days. The transplanted kidneys are all functioning.

         

        From our initial experience, laparoscopic nephrectomy appears to be both feasible and safe. Its implementation requires a combined team with experience in donor surgery and advanced laparoscopic skills. The procedure may increase the availability of living donor kidneys, due to the smaller impact on the donor compared to conventional donor nephrectomy.

        Paroxysmal atrial fibrillation (AF), a frequent cause of repeated hospitalization, is effectively treated with propafenone. The time to conversion to sinus rhythm is a consideration when managing AF in the emergency room. We investigated the conversion rates of paroxysmal AF by 3 different oral propafenone (P) regimens, in terms of time to conversion.

        188 patients with onset of AF within 48 hours were treated with propafenone (P): 48 received 600 mg as a first oral dose followed after 8 hrs by 150 mg (Group A); 82 received 300 mg as a first dose, followed by the same dose 3 and again 8 hrs later (B); 58 received 150 mg every 3 hrs, up to a total dose of 600 mg (C). P was stopped when sinus rhythm was achieved.

        Rates of conversion to sinus rhythm after 3 hrs in the 3 groups were: 46%, 41% and 26% respectively; after 8 hrs: 77%, 78% and 70%; and after 12 hrs: 81%, 84% and 76%. Treatment was discontinued in 8. There was excessive QRS widening (>25% of the basal value) in 1 in group A, 1 in group B and 2 in group C; wide-QRS tachycardia occurred in 4 in group B. In Group A there was a higher rate of early successful conversion, with a lower incidence of side-effects than with the other regimens.

        Superficial Skin Necrosis in Short Bowel Syndrome

        Short bowel syndrome causes a complex of symptoms due to compromise of small intestinal nutrient absorption. A 60-year-old woman underwent major resection of the small intestine due to a road accident 3 years ago. The sole manifestation of short-bowel-syndrome was superficial skin necrosis due to vitamin K deficiency. She was asymptomatic for a long time, until treatment with antibiotics further intensified initially subclinical malabsorption.

        It is not clear why there had been no other symptoms and why the main impact was on the fibrinolytic system rather than the coagulation system, as is usually the case. It is recommended that patients after major resection of the small intestine be closely monitored for coagulation function if an oral antibiotic is prescribed.

        The 4 allele of the APOE gene, coding for apo-lipoprotein E, is the most common genetic risk factor for Alzheimer's disease and a significant risk factor for coronary atherosclerosis. There is therefore much interest in studying its frequency in different ethnic groups.

        We examined its frequency in Jews originating from Libya, Buchara and Ethiopia and in Jews of Sepharadi and Ashkenazi origins. Its frequency among Ethiopian immigrants was 0.27, significantly higher than in the other groups, in which the frequency was between 0.067 and 0.10. These differences in allele frequency may serve as a basis for future studies in Israel to assess the relative contributions of genetic and environmental factors to the incidence of dementia.

        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.

        Ehrlichiosis is an emerging zoonotic disease transmitted to man by ticks. Its clinical features include fever, headache, myalgia, nausea and rash. The diagnosis requires a high index of suspicion; the disease has a specific serology, and has never been reported in Israel.

        We describe a 52-year-old man hospitalized with fever, a diffuse rash, arthralgia and epididymitis. Skin biopsy disclosed necrotizing small vessel disease consistent with periarteritis nodosa. Acute phase serum titer for E. chaffeensis was 1:256. Fever promptly subsided following ciprofloxacin.

        Over the past 15 years, percutaneous therapeutic cardiac catheterization has become increasingly important in the treatment of congenital heart disease. We describe our experience in 1000 such catheterizations between 1993-1997. 55% were in 1-12-year-olds; only 20% were in patients younger than 1 year old and 11.3% were in adults with congenital heart defects. In about 50% it was at least a second cardiac catheterization. Overall, there were 425 therapeutic cardiac catheterizations, increasing from 33% in the first 200 procedures, to 63% in the last 200.

        We performed 30 different types of therapeutic catheterizations: 23.3% were valvular dilations, 21.4% vessel angioplasties, 36.9% closure procedures, 9.2% electrophysiological procedures, and 9.2% miscellaneous. In 31.3% of therapeutic catheterizations we used 12 new procedures. Minor complications occurred in 8.5% and major in 0.6%; most complications were successfully treated or were self-limited and there was no residual damage.

        In this report the current role of each type of major catheterization is discussed on the basis of our experience. Further development of technology for lesions not amenable to currently available transcatheter methods, and longer follow-up for current techniques will consolidate the role of therapeutic cardiac catheterization in congenital heart 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.
