Multilocular Cystic Mass of the Kidney: A Diagnostic Challenge

Judy Kleinmann, Simon Negelev

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.

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.

The Israeli Pharmaceutical Market

Segev Shani, Joshua Shemer

The pharmaceutical market in Israel has undergone many major changes over the past 2 years. We detail measures taken with regard to drug prices and utilization, from 1992 until 1995, when the National Health Insurance Law was implemented. This provides an information base for marketing and dispensing of drugs, economic planning in the public health system, and for physicians and pharmacists in clinical practice.

The national expenditure on pharmaceuticals in 1994 was 9.4% of the annual national health expenditure. From this fact, and the number of registered drugs and the number of clinical trials conducted, it appears that our pharmaceutical market is quite diversified and well developed compared to other markets in the western world. This size advantage enables our sick funds to purchase drugs at much lower prices than the private sector.

We describe a 4.5-year-old girl in whom post transplantation lymphoproliferative disorder was diagnosed 1 year after liver transplantation. She ran a complicated course with multiple organ involvement: respiratory failure which required mechanical ventilation, renal failure, bone marrow depression and severe protein-losing enteropathy.

During the August 1998 heat wave in Tel Aviv we admitted many patients for acute heat-related illness; 6 had severe heat stroke and were admitted in critical condition. We describe their clinical courses during the first 5 days of hospitalization, including response to treatment and implications for future management of this disorder.

The mean APACHE II score of the 6 was 30±3.5 and mean Glasgow Coma Scale rating 3.5±0.5; they were in hypovolemic shock and respiratory failure, necessitating mechanical ventilation. Despite early effective therapy (core temperature in all was reduced to less than 398C in less than 1 hour), there was 1 death (mortality 15%) and 4 required further intensive care for life-threatening multiple organ failure.

During severe heat waves a significant number of referrals for acute heat-related illness must be anticipated, possibly overwhelming admission capacity of regional intensive-care units. Severe heat stroke complicated by multi-organ failure is not necessarily related to prior physical activity. Although important in determining prognosis, early treatment does not prevent severe complications. Mechanisms regulating body heat may remain disturbed for days following early treatment and apparent stabilization, mandating continued hospitalization.

The New Family Physician

The content of all consultations of a family physician during the first 2 months in a new practice and again in the same 2 months, 2 years later were analyzed. The workload did not change between the 2 periods, but in the first period there were relatively more men over the age of 60 years, and a more marked predominance of women in the 45-59 year age-group.

There were more follow-ups of pre-existing conditions during the first period, but in both periods the main reason for visits was an acute condition; a quarter of visits required only simple counseling without further investigation or prescribing of medication. During the first period 9% of visits were for the explicit purpose of getting to know the new physician, usually by women.

Thus the initial period in a new practice is not excessively burdensome, but involves seeing a number of patients who come either simply to get to know the new doctor, or to present non-chronic problems without expectation of further investigation.

We assessed the prevalence of self-reported medical complaints among the community-dwelling elderly receiving regular medication, and determined associations between health and sociodemographic variables, and the prevalence of complaints.

The study included 170 patients, 60-90 years of age, living at home. Participants were recruited from the 3 main primary care clinics in Rishon LeZion. All were receiving chronic medication and were followed-up utilizing a long-term medication card. Data were gathered in interviews held in patients' homes using a structured questionnaire which included sociodemographics, diseases and medication, mental state assessment by Katzman's score, and a list of 15 medical complaints common among the aged. Relations to age, gender, education, living arrangements, number of diseases and number of medications per patient were determined.

Mean age of participants was 73.2±6.0 years and they suffered an average of 4.07±2.16 diseases and took 5.10±2.83 types of drugs. The most prevalent complaints were: weakness and fatigue (65.0%), agitation and restlessness (56.4%), dry mouth (45.6%), constipation (43.6%) and dizziness (43.2%). The number of diseases, gender, education and age had the strongest associations with the prevalence of specific complaints, as well as their total number. The association between number of medications and mean number of complaints was of borderline significance.

Limited Percutaneous Surgical Drainage in Severe Neonatal Necrotizing Enterocolitis in Low Birth Weight Prematures

The usual treatment of complicated neonatal necrotizing enterocolitis (NEC) is resection of the necrotic bowel, lavage of the peritoneal cavity and diversion enterostomy. Low-birth-weight premature neonates with this condition are in special danger if general anesthesia and full exploratory surgery is contemplated.

A relatively simple alternate procedure is percutaneous insertion under local anesthesia of a soft abdominal drain, most often in the right lower quadrant. The procedure is done in the neonatal intensive care unit without moving the whole set-up to the operating room.

4 such cases have been treated within the past year. 3 were discharged home as they did not require additional surgical treatment, not having developed intestinal stenosis or obstruction. 1 recovered from the acute episode, but succumbed to a severe intraventricular hemorrhage and respiratory failure 7 days after the procedure.

Our limited but most gratifying experience, in addition to similar experience of others, encourages us to recommend this simple surgical approach in the very sick low-birth-weight premature with fulminant NEC.

Neuropsychiatric Side Effects of Malarial Prophylaxis with Mefloquine

T. Minei-Rachmilewitz

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.

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.
