Severe Transient Neutropenia due to Parvovirus B19

D. Heldenberg

Dept. of Pediatrics, Hillel Yaffe Medical Center, Hadera

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.

Multilocular Cystic Mass of the Kidney: A Diagnostic Challenge

Urology Dept., Assaf Harofeh Medical Center, Zerifin

Multilocular cystic masses of the kidney present a diagnostic challenge because they may be malignant. Renal cell carcinoma with multilocular cysts has been reported. We present 4 cases in which the preoperative differential diagnosis was between a benign and a malignant multilocular cystic kidney mass.

Our results, combined with those of 33 previously reported cases, reveal that only 32% of cases were diagnosed correctly preoperatively. In 21% of these patients the preoperative clinical evaluation did not correctly diagnose malignancy: 24% of them yielded false negative and 21% false positive results. Angiography was more accurate than CT, US or aspiration of cysts. Frozen section was inaccurate in 55% of cases.

There is no reliable diagnostic test to distinguish between a malignant and a benign multilocular cystic mass. Invasive angiography is more accurate than other modalities. A therapeutic decision has to be made between nephron-sparing and radical surgery in each case. When nephron-sparing surgery is considered, the possible need to perform radical nephrectomy in second-look surgery must be taken into account.

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.

Biofeedback Unit, Psychiatric Ward, Sheba Medical Center, Tel Hashomer

Irritable bowel syndrome is a group of heterogenic complaints of functional bowel disorder in the absence of organic pathology. The pathophysiology is unclear. In most cases treatment includes symptomatic remedies, antidepressants, psychotherapy and hypnotherapy.

Biofeedback has recently been introduced as a therapeutic modality. Treatment also includes relaxation techniques and guided imagery, together with computer-assisted monitoring of sympathetic arousal. Biofeedback requires active participation of patients in their healing progress and leads to symptom reduction in 2/3.

Familial hemiplegic migraine is a rare autosomal, dominant, migraine subtype. It is characterized by acute episodes of hemiplegia and hemisensory deficits, and other neurological abnormalities occurring either before or together with severe headache, nausea and vomiting; episodes last several hours and then spontaneously subside. Intervals between episodes are relatively prolonged. Unless there is a relevant family history suggesting this syndrome, the diagnosis is usually delayed. Recently the gene for the syndrome was identified on chromosome 19. We report 3 boys and 1 girl, 11-15 years old with hemiplegic migraine.

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.

Urethral catheterization, the standard method of measuring residual urine, is uncomfortable and associated with risk of infection and trauma to the urethra. It has also been reported as inaccurate to a certain extent. We compared catheterization with ultrasound scanning in a prospective study of 52 men and 3 women.

100 measurements of postvoiding residual urine by portable ultrasound scanner, were each followed immediately by urethral catheterization (both procedures performed by an experienced nurse in our outpatient clinic). A difference of >25€ml between measurements by scanner and by catheter was considered significant.

The range of residual urine measured by scanner was 1-425 ml, and by catheter 1-410 ml. There was good matching between the 2 methods in 85 of 100 measurements (scanning accuracy 85%). In 30/85 matching was excellent while in 55 cases the mean difference was 8.5±6.2 ml, range 1-24 ml. The accuracy of scanning was 85%; there was perfect matching between the 2 methods in 30 cases. In the remaining 15 cases the mean difference was 41.8±13.6 (range 25-56).

Each catheterization took 4-5 minutes and scanning 30 seconds. There were no complications after catheterization, but all reported discomfort and dysuria for 1-2 hours thereafter. Scanning was absolutely uneventful in all.

The cost per catheterization, including medication, disposable materials and personnel time was approximately 80 NIS. Our 80-90 measurements of residual urine a month require annually about 80 hours and a budget of about NIS 80,000. Scanning requires only 8 hours, while the cost of the portable scanner is significantly less than NIS 80,000 and it can be used for more than a year.

We conclude that measuring urine residual with the noninvasive scanner instead of by catheterization is easier, more accurate, and more cost-effective.

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.

We reviewed the charts of 100 consecutive emergency department (ED) cases of injuries in public buses (not due to actual traffic accidents) seen during 7 months in 1995. There were 29 males and 71 females with a mean age of 55.6-21.4 years, median 60, and range 13-91. 92 were discharged home directly from the ED. 3 were admitted to general surgical wards, and 1 each to the orthopedic, medical and neurosurgical wards, while 2 soldiers were sent for observation to a military clinic.

There were 28 spinal column, 27 head and 25 chest injuries; 1 patient died. There were no significant differences in admissions during the months of the year. 58% of injuries occurred during normal working hours, with a peak incidence at about 1000 hrs. The most common cause was falling while standing, due to sudden acceleration/deceleration or sharp turns.

There are 1900 buses in Tel Aviv which carry 1.1 million passengers daily and most of which are capable of significant acceleration. A high proportion of passengers travel standing, and elderly passengers are more liable to fall when the bus accelerates, decelerates or turns. We calculate a potential national yearly bus injury toll from falls of more than 1000, which often result in significant morbidity and even mortality. A national survey is now being planned.

Mirena, a new intra-uterine device (IUD) introduced in Israel during the past year, releases 20 mcg/day of levonorgestrel for 5 years. It has the advantages of reduced pregnancy rates and diminished menstrual blood loss, together with a low risk of pelvic inflammatory disease compared with current IUD's.

It has a typical sonographic appearance, differing from that of regular IUD's, which was demonstrated in all 15 women examined in this study. Its sonographic appearance includes both proximal and distal ends of the vertical arm of the device, which extend into the internal cervical os and fundal region, respectively. Acoustic shadowing between both ends defines the location of the device, which should help avoid consultations due to "lost IUD's."

A 23-year-old woman was admitted with a history of 2 weeks of cough, fever and bilateral lung infiltrates. She had been diagnosed 2 months before as having ulcerative proctitis and was treated with mesalamine, which induced a full remission, but 3 antibiotic regimens failed to improve her lung disease.

Since computerized tomography revealed bilateral peripheral lung infiltrates and her eosinophile count was elevated, the diagnosis of drug-induced eosinophilic pneumonia was suggested. Mesalamine and antibiotics were stopped and oral corticosteroids begun. She became almost asymptomatic a week after mesalamine withdrawal, and the x-ray became normal.

Neuropsychiatric Side Effects of Malarial Prophylaxis with Mefloquine

T. Minei-Rachmilewitz

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.
