There has been continuous debate over the superiority of primary percutaneous, transluminal, coronary angioplasty (PTCA) over thrombolysis for acute myocardial infarction (AMI). It was questioned whether this advantage of primary PTCA reported in selected populations by experienced centers can be replicated in our clinical practice.

We compared demographic and clinical variables, therapies and outcome in AMI treated with primary PTCA vs thrombolytic therapy. Clinical and demographic variables of 1,678 unselected AMI patients (admitted January/February and May/July 1996) were analyzed in 16 cardiac care units with on-site catheterization facilities and ability to perform PTCA. Of these 803 (48%) were treated by thrombolysis and 99 (6%) by primary PTCA.

The prevalence of adverse prognostic variables, such as anterior wall MI, heart failure on admission or during hospital stay, pulmonary edema, and ventricular tachycardia or fibrillation, was higher in the PTCA group. The 7-day, 30-day and 1-year mortality rates were similar in the 2 groups: 4%, 7.2% and 12.8%, respectively, in the PTCA group and 5%, 7.2% and 11.1% in the thrombolysis group. There was a trend toward lower mortality in subgroups of high-risk patients: those with heart failure on admission (Killip class >1), the elderly (>65 years), and those with previous MI treated with PTCA. After adjusting for confounders, treatment with primary PTCA was not found to be associated with lower mortality.

Only a small proportion of AMI patients in Israel were treated with primary PTCA in 1996. The frequency of adverse prognostic factors among them was higher but their short and long term outcomes were similar to those of high risk patients treated with thrombolysis.

Breast cancer can be detected by scintimammography using Tc-99m sestamibi (MIBI). The method is highly accurate, sensitive and specific. Histologically, most of the tumors have been adenocarcinomas.

We present 2 women with rare breast tumors, primary squamous cell carcinoma and malignant phyllodes tumor. In both, mammography and cytological biopsy were not diagnostic, but MIBI scintimammography demonstrated focal uptake in the diseased breast.

Palmar hyperhidriosis is not a life-threatening disease but leads to loss in the quality of life. Conservative treatment is ineffective and major surgery involves perioperative complications and esthetic impairment.

From 1992 to 1998 we treated 156 patients with palmar hyperhidriosis using a single port, drainless videothoracoscopic procedure with almost no complications.

Amplification of specific DNA sequences by polymerase chain reaction (PCR), enables rapid, sensitive and direct, specific identification of pathogens at very low concentrations in clinical samples. Studies in recent years have reported identification of several enteropathogens directly from stool samples by PCR. The amplification process includes the use of primers complementary to the DNA sequences specific to the pathogen, thus relying on the pathogen's genotype, rather than its phenotype on which identification by the methods of classical microbiology were based.

We have developed PCR protocols for the differential identification of enteropathogens resembling the normal flora (enterotoxigenic E. coli (ETEC), E. coli O-157), Shigella spp, and the detection of enteropathogens that can not be grown on classic growth media (Norwalk virus). The amplification process is inhibited by several substrates present in fecal material (phenol, hemoglobin), limiting DNA extraction by phenol. The protocols we have developed for direct detection of Shigella spp and ETEC in stools circumvent inhibition of PCR by the use of a 4-hour pre-enrichment step in brain-heart infusion broth.

Rapid and accurate identification of enteropathogens is important for prompt and focused intervention to stop the chain of transmission in outbreaks of gastroenteritis in military and civilian populations.

About 2500 soldiers were injured during the Six Day War (June 1967) of whom 115 suffered from burns. In 34 of them 15% or more of their body surface was involved and 11 died. Typical features of these burn cases were supplementary injuries, a high rate of infection, and long periods of hospitalization. Prophylactic antibiotics were not useful. The general condition of many deteriorated during the first week after injury, indicating the importance of treating severe burns in specialized facilities.

Osteoarthritis results from progressive catabolic loss of cartilage proteoglycans due to imbalance between synthesis and degradation. The availability of glucosamine, an intermediate in mucopolysaccharide synthesis, can be rate-limiting for proteoglycan production in cartilage tissue culture.

57 patients suffering from osteoarthritis of the knee were randomized into a group treated for 4 weeks with daily IV glucosamine sulfate (GS) together with 800 mg chondroitin sulfate, and a placebo group. Knee pain at rest, on movement and on palpation, as well as range of knee motion were then recorded.

In the GS group, there was significant reduction of clinical symptoms (p<0.01), but no significant reduction in the placebo group. Physicians' assessment of tenderness and range of motion were significantly in favor of the GS group (p<0.01). In those treated with glycosamine there were no adverse reactions and no changes in laboratory blood tests.

Transient Ischemic ECG Changes in Acute Cholecystitis without History of Ischemic Heart Disease

That abdominal distention, nausea, and chest pain may be accompanied by ischemic ECG changes is well known and has been described in the literature. However, very few cases have been reported with acute cholecystitis and ECG changes not due to cardiac ischemia.

We present a previously healthy 20-year-old woman admitted with acute cholecystitis. Prior to surgery routine ECG showed ST-depression and T-wave inversion. The day following cholecystectomy the ECG returned to normal. 1 month later, ergometry and echocardiography were both negative.

Based on the literature and our personal experience, although ECG changes may occur in acute cholecystitis, the possibility of cardiac ischemia must be excluded. However, when no cardiac basis is found, ultrasound of the biliary system might reveal the cause of these ECG changes. Thus, in acute cholecystitis with ischemic ECG changes but no other laboratory or clinical evidence of cardiac ischemia, ECG changes alone are not a contraindication to cholecystectomy. Furthermore, delay in treatment could be harmful.

37 candidates for epilepsy surgery underwent the intra-carotid amytal procedure (IAP; also known as the Wada test) to determine hemispheric speech dominance and memory capacity. 31 demonstrated left hemisphere speech dominance, 2 showed evidence for bilateral language and 4 demonstrated right hemispheric language dominance.

Our study supports a correlational relationship between handedness, lesion laterality and age of onset of seizures, as reported in earlier studies. Left-handed patients with a left hemisphere lesion whose seizures began to an early age had a strong tendency for reversed language dominance.

Asymmetry of at least 20% in performing the memory test was taken as the cutoff score for demonstrating laterality of lesions. The asymmetry score correctly predicted laterality of lesions in all 28 patients; 6 did not have asymmetry scores and 3 were examined for language only. None of the patients who successfully passed the Wada memory test had any significant postsurgical memory deficits; 1 had transient reduction in verbal memory and 4 who did not pass the test were not operated on for this reason.

Our results demonstrate the importance of the Wada test in determining cerebral speech dominance, in predicting post-surgical amnesia, and support its usefulness in predicting laterality of seizure focus in candidates for temporal lobectomy.

Acute epidural hematoma is very rare in the elderly after head injury. It is usually associated with extremely high mortality or severe disability. In an 87-year-old woman a large, hyperacute, epidural hematoma was diagnosed. She was treated promptly and enjoyed an uneventful, complete recovery. This exceptional case should encourage an intensive approach even in seemingly minor head trauma in the elderly.

A recent further development in laparoscopic surgery is microlaparoscoopy. The technique is identical to standard 10 mm laparoscopy except for the use of small, 2 mm scopes and trocars. We used this technique in 19 patients treated from June 1998 to February 1999.

The advantages of microlaparoscopy are: smaller incisions, less risk of damage to pelvic organs and less postoperative pain. However, the use of microlaparoscopy for operative procedures is limited to simple operations due to the limited field of vision. We urge our colleagues to consider microlaparoscopy whenever diagnostic laparoscopy is needed.

Nocturnal Eating Disorder - Sleep or Eating Disorder?

Nocturnal eating disorder (NED) is a rare syndrome that includes disorders of both eating and sleeping. It is characterized by awakening in the middle of the night, getting out of bed, and consuming large quantities of food quickly and uncontrollably, then returning to sleep. This may occur several times during the night. Some patients are fully conscious during their nocturnal eating, while some indicate total amnesia. The etiology of NED is still unclear, as research findings are contradictory.

Those suffering from NED exhibit various levels of anxiety and depression, and many lead stressful life-styles. Familial conflict, loneliness and personal crises are commonly found. Recently, a connection has been discovered between NED and unclear self-definition, faulty interpersonal communication, and low frustration threshold. Several authors link it to sleepwalking, leg movements during sleep, and sleep apnea. Treatment is still unclear and there have been trials of pharmacotherapy, psychotherapy, or a combination of both. However, pharmacological treatment has generally been found to be the most effective, although each case must be considered individually.

In 1998, 7 women referred to our Eating Disorders Clinic, 5% of all referrals, were subsequently diagnosed as suffering from NED. Of these, 3 suffered from concurrent binge-eating disorder and 4 also from bulimia nervosa. 2 case studies representative of NED are presented.

Type 2 diabetes has been considered rare in children and adolescents. Recently, increase in the incidence of type 2 diabetes has been reported among adolescents in various parts of the world. We report the occurrence of type 2 diabetes among adolescents in Israel.

A boy of 14 and girls of 16.5 and 17 were pubertal and extremely obese, with a body mass index (BMI) between 39-47 kg/m². Acanthosis nigricans, elevated diastolic blood pressure, and hirsutism with menstrual disorders, were associated with insulin resistance, and should raise suspicion of type 2 diabetes. Significant obesity and strong family histories of type 2 diabetes appeared to be important risk factors. Since type 2 leads to long-term morbidity and mortality, its early identification and appropriate treatment are crucial.

It is clear to experts in the health care industry that with regard to medical decision-making, considering costs of medical devices is not a good index, but it is highly important to include medical aspects. This approach guarantees an advance and an appropriate method.

We present a cost-effectiveness analysis to target the optimal strategy of how to use medical diagnostic devices in cases of knee injuries. Today, one of the more common medical emergency referrals seen worldwide is in the area of orthopedics, knee injuries in particular. They can harm soft tissue, bone tissue, or both simultaneously. The diagnosis of soft tissue injury is difficult at best. Among the devices helping the clinician make an accurate diagnosis are MRI and ultrasound (US).

We conclude that US is superior to MRI in this condition. This is especially true when the orthopedic examination leads to the suggestion of arthroscopy. The results were not modified, and a sensitive study of the parameters that influence the decision- making process was undertaken. Decision-makers should not consider medical outcome alone, but should take into account the costs. A clinical study should validate the assumption on which this study was based.

Gyrate atrophy of the choroid and retina is a rare degenerative disease, characterized biochemically by a marked increase in blood ornithine levels, due to deficiency of ornithine S-amino transferase. 4 men aged 35, 36, 48 and 62 years are described with different stages of myopia, night blindness and loss of peripheral vision, which progressed to tunnel vision and partial blindness. Onset of the disease was at ages 3, 10 and 15 years, respectively, while in the 4th patient there was delayed expression starting at about age 50. Most had posterior subcapsular cataracts, and the ocular fundus exhibited demarcated circular areas of chorioretinal degeneration. So far the only patients described in Israel have been of Iraqui origin. Our fourth patient originated from Istanbul, and he may represent a hitherto undescribed variant with a much delayed expression of the disease.

Since the advent of extraperitoneal approaches for laparoscopic surgery, the creation of extraperitoneal virtual spaces has spread rapidly. We describe our preliminary experience with selective neck exploration and endoscopic parathyroidectomy in 4 women, aged 57-74, with primary hyperparathyroidism.

Preoperative localization of parathyroid adenoma was assessed by technetium-sestamibi scanning and cervical ultrasonography. A cervical work space was created by the introduction of a trocar with an inflatable balloon-tip and maintained with low-pressure CO² insufflation. All procedures were completed endoscopically. There were no intraoperative complications. Mean operative time was 40 minutes and cosmetic results were very satisfactory.

We found endoscopic parathyroidectomy a feasible and safe option and particularly appropriate for the surgical treatment of primary hyperparathyroidism. Further refinements in technique will enhance its practicability in exploring the mediastinum for ectopic parathyroid glands and in those with secondary hyperparathyroidism.
