Pulmonary embolism is a common event in hospitalized patients. In some cases it presents with hemodynamic collapse, indicating massive obliteration of the pulmonary vasculature and has a very grim prognosis; 2/3 of such patients die within 2 hours of onset of symptoms. We describe our experience in 13 patients with massive pulmonary embolism. An aggressive diagnostic and therapeutic approach, utilizing sophisticated imaging techniques, thrombolytic therapy and surgery, led to the survival of 8 of the patients. Our experience supports an aggressive approach in these seriously ill patients.

The dramatic course of necrotizing soft tissue infection represents a medical emergency, since it is limb - and life-threatening. Most necrotizing soft tissue infections are caused by mixed aerobic and anaerobic Gram-negative and Gram-positive organisms. Most case have been reported in immunocompromised hosts after penetrating trauma or surgery. We describe a unique series of cases of necrotizing soft tissue infection. The mainstay of treatment is early and daily debridement of devitalized tissue and broad-spectrum antibiotics. Hyperbaric oxygen therapy should be considered.

In the past 15 years there has been continuous increase in the use of injections into the corpora cavernosa of different vasoactive drugs for treatment of erectile dysfunction (ED). However, some of these drugs are very expensive, are not available everywhere, and have side effects. We therefore compared the success rate of the most widely used compounds, papaverine and regitine, in 452 patients (age range 26-85) with different types of ED. Each patient received in the clinic injections of papaverine, 6-25 mg, and regitine, 0.05-1.5 mg. When maximal rigidity of the penis (MRP) was >80%, we instructed the patient to self-inject the drug at home, 5-30 minutes before coitus. If after 3 injections MRP was not >80%, prostaglandin E1 (PGE1) in an average dose of 10-25 mcg was added. If there was no response, papaverin+regitine+PGE1 were given in higher dosage, and atropine sulfate, 0.02+0.06 mg, was added if necessary.

Of 452 patients, 305 (67.4%) had MRP >80% after 3 injections of papaverine plus regitine. The other patients received PGE1 in addition. This was helpful in 61 patients (41.5%), while 55 (63.9%) required papaverine + regitine + prostin in higher doses. Of these, only 31 received papaverine + regitine + PGE1 + atropine sulfate. Of these, 20 (64.5%) reached MRP >80%, and 11 (2.4%) MRP <60. For these 11 patients, we recommended a penile prosthesis. Thus in 67.4% of the 452 patients, papaverine + regitine injections were effective; in 41.5%, PGE1; in 63.9%, papaverine + regitine + prostin + atropine sulfate. Only 11 (2.4%) did not react to intracorporeal injection.

This progressive method of treatment enabled us to select the optimal dosage and combinations of compounds in 441/452 patients (97.5%) according to the severity of their dysfunction. During follow-up of 6 months, spontaneous erections without injection were achieved in 115 (26.0%).

There is inherited predisposition to breast and ovarian cancer in 5-10% of all women with these diseases. Germline mutations in BRCA1 and BRCA2 presumably account for most of the genetically susceptible individuals. We summarize 2 years of experience in counseling and testing for inherited predisposition to these cancers.

597 women (from 320 families) have been evaluated since August 1995. 242 were evaluated for inherited predisposition to breast and ovarian cancer. One-third had clear-cut evidence of familial background. 74 families were of Ashkenazi origin; the age range of breast cancer was 30-35, of ovarian cancer 40-45. In 80% of families other cancers were also noted in first degree family members, including lung, colon, and prostate cancer and leukemia.

Genetic testing revealed that 45% of affected and 25% of unaffected women were carriers of a mutation in BRCA1 or BRCA2: 67/90 185delAG (BRCA1), 12/90 6174delT (BRCA2), and 4/90 of 5382insC (BRCA1). In addition, a novel mutation in exon 11 of BRCA1 was detected, carried by 7/90 women. The experience gained in oncogenetic counseling and genetic testing for inherited cancer predisposition will eventually enable determining an optimal, rational therapeutic regimen in carriers of mutations.

Acute hyperparathyroidism is a rare and dangerous condition. It is supposed to result from transformation of a mild chronic form into an acute and stormy illness. The causes and the mechanism of such a transformation are usually unknown. A case of acute hyperparathyroidism is presented in which hemorrhage into a parathyroid adenoma was recognized and diagnosed as the immediate cause of the transformation from the mild long-standing form of the disease into the severe acute form.

We studied the social and cultural frameworks that impact on breast cancer patients in the medical system. The subjects were 98 Jewish women who had undergone mastectomy or lumpectomy for cancer 6 months to 3 years prior to the interview. They emanated from a variety of socioeconomic and ethnic backgrounds, and reflected the age range of women with breast cancer in the general Jewish population of Israel. Patients were asked about each stage of the medical process they had experienced: diagnosis, surgery, oncological care, and follow-up care. The interview revealed a general perception of having received insufficient information regarding their medical condition and treatment. The problem tended to be most severe during the diagnostic stage, when women had not yet been officially included as patients within the system. The problem was relatively severe during follow-up care, when they often did not have an address for their questions. Few women received a schedule of follow-up care that allowed them to carry on with the many necessary tests in an orderly and comprehensive manner. Most important, systematic absence of informed consent also characterized the decision-making process regarding surgery and oncological treatment. Few women felt they had been informed about treatment options, side-effects, or long-term implications of the treatment offered. We found no indication of inequitable medical treatment that would suggest a manifest pattern of discrimination, but we did find some social variables related to a feeling of insufficient personal care and information. In particular, older women said they received less attention, support, and information from the medical staff relative to the younger women.

A prospective study of the effect of cataract extraction with intraocular lens implantation on the course of diabetic retinopathy (DR) in 44 patients (59 eyes) was carried out. It showed that in the 1-3 years following surgery, there was progression of DR (including development of newly formed retinopathy) in 35% of the patients (28.8% of eyes). Progression was more marked in patients with pre-operative bilateral DR compared to those without bilateral DR (77% and 16% respectively). Insulin dependence did not play a role in progression. Final visual acuity was better in patients without pre-operative DR, as well as in eyes without progressive retinopathy.

The potential parapharyngeal space contains the great vessels of the neck, cranial nerves IX-XII, the sympathetic chain and lymph nodes. Surgical access is difficult and the infrequency of tumors in it make surgery of this part of the head and neck a challenge. 8 women and 2 men (mean age 54.7, range 31-70 years) with tumors of the parapharyngeal space operated on during the past 6 years are presented. The most common surgical approach was the cervical submandibular, used in 6 of our patients with relative ease and minimal complications. Tumors of deep lobe parotid origin should be operated through a transparotid approach. Large benign or malignant tumors have a better prognosis when the transcervical transmandibular approach is used, providing wider access.

It is often difficult to assess accurately the nature of a skeletal lesion. Problems include differentiating a malignant from a benign bone tumor, as well as determining the cause of a pathologic fracture. Such fractures may occur through osteoporotic bone as well as through neoplasm-affected bone. Thus, development of an imaging modality capable of distinguishing between such lesions is of importance. During 1996, we ran a prospective study in which results of Tc-99m-methyl-diphosphate (MDP) bone scans were compared with those of sestamibi (MIBI) bone scans and with subsequent biopsy and clinical course. The results of the bone scans were assessed by 2 independent "blinded" observers, and the ratios of counts in lesions to those in normal tissue (L/N ratios) were calculated. In cases of malignant (7) and benign (8) tumors, intensity of uptake in MDP scans were not predictive of degree of aggressiveness. On the other hand, MIBI bone scans demonstrated significant difference in intensity of uptake between benign and malignant bone tumors (L/N ratios 2.05 vs 2.75). In 5 of 8 benign lesions the L/N ratio was 1. In the others, increased uptake was minimal. In 2 patients changes in uptake in MIBI bone scan following chemotherapy appeared to be related to the degree of tumor necrosis achieved. While the MIBI bone scan cannot replace tissue biopsy as a definitive diagnostic modality in bone neoplasms, it does appear to allow better preoperative assessment and prognosis.

Macroenzymes: an Interesting Laboratory Finding, without Clinical Relevance

Macroenzymes are complexes of serum enzymes with proteins which have a higher molecular weight and longer plasma half-life than the normal enzyme. The presence of macroenzymes is suggested by finding increased serum enzyme activity, not associated with symptoms. Thus, macroenzymes can cause diagnostic errors and the performance of unnecessary tests or invasive procedures. We describe 2 patients with highly elevated serum levels of lactate dehydrogenase (LDH) and creatine kinase (CK) due to formation of complexes with immunoglobulin G. 1 patient had LDH of 4500 u/L but was otherwise normal and in the second CK was elevated with no evidence of ischemic heart disease. Awareness of the phenomenon of macroenzymes may save the patient long and sometimes invasive investigation.

Diarrhea is still a major cause of morbidity and mortality among children in developing countries. The Bedouin population of southern Israel is in transition from a nomadic to a settled life-style. We examined maternal knowledge and reported behavior when their children had diarrhea. Mothers defined diarrhea as the passing of 4-5 stools per day. The most frequent signs of the illness were an increased number of watery stools with changes in either color or form. The most frequent symptom that prompted mothers to seek medical aid was blood in the stool. All mothers reported increasing fluid intake in their children during diarrhea, and most reported giving herbal tea. About half of the women avoided milk products and used special for the treatment of diarrhea. A quarter of the women reported stopping or decreasing the frequency of breast feeding during diarrhea. Reported cessation of breast feeding during diarrhea was associated with changing to special foods, and failure to note the onset of diarrhea or to recognize signs of dehydration. The withdrawal of breast feeding during episodes of illness and diarrhea is related to lack of knowledge regarding diarrhea. These data indicate that even in this population, with free access to preventive and curative medical care, there should be greater efforts to educate mothers to detect diarrheal disease and to maintain breast feeding during the diarrhea.

The relationship between angina pectoris and the severity of coronary artery disease was evaluated in 146 patients with normal segmental and global, left ventricular, systolic performance. None had unstable angina or a previous myocardial infarction. A strong relationship was found between angina and the severity of coronary artery disease (p<0.005). Significant, stable, angina pectoris as a clinical symptom indicated advanced coronary artery disease in this selected group of patients.

Diarrheal diseases weigh heavily on the health of children, especially in developing countries, but also impose burdens on health care services worldwide. This study was performed to determine whether patterns of referrals in the Negev to the pediatric emergency room (PER) for diarrhea differ between the Jewish and Bedouin populations of the Negev, and the extent of the burden imposed on the PER and in-hospital services in the Negev. Characteristics of referrals and hospitalizations were examined from March 1994 to February 1995. Of the 27,834 referrals to the PER for children under 16, 2518 (9%) had diarrhea and there were 5,169 hospital admissions, 701 (13.6%). The annual rates of referral were 146 per 10,000 in Jews and 225 in Bedouin, giving an odds ratio (OR) of 1.5 (p<0.001). for Bedouin. The rates of hospitalization were 23 per 10,000 in Jews and 99 in Bedouin (OR 4.4, p<0.001). 1380 (54.8%) of the PER referrals were of infants under a year of age. For hospitalization, the annual rates were 164 per 10,000 in Jews and 756 in Bedouins (OR 4.9, p<0.001). During June to August referrals and hospitalizations for diarrhea were significantly higher, and from December to February significantly lower than during the remaining months. These differences arise from the marked seasonal pattern in the Bedouin population, whereas in the Jewish population there was no seasonal variation. Even in the 90's the burden on health services in the Negev as a result of diarrheal illness is considerable and the Bedouin population still contributes to that burden disproportionately. There is need both to reduce the gap in referrals and hospitalization between the populations, as well as to reduce the rates, using currently available means such as education, while developing new technologies, such as vaccines.
