Background: The consultation is the pivot of clinical teaching in ambulatory care. It is therefore essential that students observe the consultation. The students' presence itself influences the consultation and also requires the patients' consent. Moreover the introduction in Israel of the ``Patients' Rights Act'' in 1996 has made us more acutely aware of the place of the patient in teaching especially with regard to the consent to be part of the teaching process.

Aim: This study was undertaken in order to investigate how tutors in family medicine perceive changes in the consultation caused by the presence of students.

Methods: An anonymous physician questionnaire was distributed on the first day of the 6th year clinical clerkship in family medicine. The questions pertained to perceived influence on length and content of the consultation. In addition physician and patient background information was gathered; and the physicians were asked to estimate the patients' willingness to be part of the teaching process.

Results: 46 tutors in family medicine participated, 70% of whom were female. Sixty four percent of the doctors thought that the student's presence had an influence on the consultation. Ninety one percent thought that it increased consultation length, especially of the physical part (93%). More than half thought that the student's presence might interfere with asking intimate questions. The majority held the opinion that the patient's gender and socioeconomic background were inconsequential. Ninety two percent of physicians estimated that 5% or less of the patients would refuse the presence of a student.

In conclusion: Tutors in family medicine think that the presence of a student affects the consultation. Those involved in and responsible for teaching should take this into account. Further research of these changes with objective measurements is needed.

The increase in prevalence of tuberculous meningitis during the past decade has been attributed in part to the increase of AIDS. Failure to diagnose HIV can cause irreversible damage and even death. We describe a man with AIDS admitted through the emergency room because of high fever and headaches for more than a month, He was cachectic and had nuchal rigidity without major neurological deficit. Brain imaging was normal and lumbar puncture showed neutrophils, lymphocytes, hypochloremia, elevated protein, and decreased glucose; cryptococcal antigen was negative but acid-fast staining was positive.

Anti-TB chemotherapy was started using 4 drugs and dexamethasone was also given. Considerable improvement in his general condition followed rapidly.

Use of corticosteroids in tuberculous meningitis has been a major issue. They are added to antimicrobial agents in order to decrease reactivity of inflammatory mediators and thus reduce central nervous system damage.

We review several controlled studies in which steroids were added to treat tuberculous meningitis. The conclusions of most were that they decrease morbidity and mortality, especially of those moderately to severely ill. Most considered as ungrounded the possibility of exacerbating latent tuberculous, or any other opportunistic infection outside the central nervous system. However, it is currently recommended to add prednisone, 1 mg/kg/d for 2-4 weeks when initiating antituberculous treatment.

There are more than 200 procedures for repairing stress urinary incontinence. We evaluated the safety and efficiency of the Burch laparoscopic procedure in 32 women with urodynamically proven genuine stress incontinence.

Mean operating time was 40 minutes and mean hospitalization time after the procedure was 30 hours. The cure rate was 97%, similar to that rin other studies (80-95%). The major complications w2 cases (6.2%) of unintended bladder injury, diagnosed and repaired laparoscopically. Although follow-up has only been for 3-42 months, the high cure rate and safety and advantages of laparoscopy over laparotomy, make laparoscopic Burch colposuspension the procedure of choice for repairing stress incontinence.

Liver transplantation is the treatment of choice for end- stage liver disease. During the past 8 years we performed 102 liver transplants in 84 adults and 16 children. In the adults, 9 were combined transplants: 1 a liver-pancreas transplant for type I diabetes, and 8 liver-kidney transplants. In the children, transplants included 5 whole-livers, 5 left-lateral liver segments from living-related donors, 4 reduced-grafts of right or left lobes, and 2 split left-lateral segments.

At a mean follow-up of 31 months (range 1-96) 70 were alive, 3 had died during surgery and 15 during the first postoperative months. Mortality was due to primary graft non-function (7), sepsis (10), intracranial hemorrhage (1), tumors (4), recurrent hepatitis B (2), biliary strictures (2) and chronic rejection (1). The 1- and 4-year survival rates were 79.5% and 69.6%, respectively.

After transplantation, 10 developed biliary stricture (5 corrected by balloon dilatation) and 8 anastomotic stricture (7 corrected by surgery), and there were 2 multiple intra-hepatic strictures. There was hepatic artery thrombosis in 5, including 4 children. In 3, grafts were salvaged by thrombectomy and 2 others underwent re-transplantation. In those who survived transplantation by more than 1-month, recurrent hepatitis B was seen in 6 of 17 (35%) and recurrent hepatitis C in 12 of 19 (63%).

Thus, results of our first 100 liver transplants are similar to those reported by larger centers, showing that in an appropriate setting good results can be achieved by small transplant programs.

In the 1950's many IDF soldiers were hospitalized for heat stroke - about 25% of whom died. Analyzing these cases revealed that commanders misinterpreted human ability to perform in the heat and ignored basic concepts of fluid and electrolyte balance and heat load.

In the early 1960's a series of studies was conducted with regard to soldiers' performance in the heat. The first study (1959), which later became a classic, was conducted during a 21-day march from Eilat to Metula, crossing all climatic zones of Israel. The study was followed by other investigations which approached the issues of voluntary dehydration, fluid consumption vs sweat loss, salt additives, and the effect of heat load on performance.

Based on these early studies, proper regulations were issued to field officers. Over the years, the lessons learned from these studies saved many lives. The number of cases of heat stroke and of other climate-related injuries was dramatically reduced, and performance was enhanced.

Flying may expose passengers to hypoxic conditions, which may induce hypoxemia, particularly in those with chronic heart and/or lung disease. Onset of dyspnea, wheezing, chest pain, cyanosis and right heart failure can lead to urgent need for oxygen during flight. The hypoxia inhalation test (HIT) provides a safe and simple means of identifying those who may develop hypoxemia during flight.

We report our experience with 48 self-reporting patients who underwent HIT prior to pre-planned air travel. They inhaled for 15-minute periods a reduced oxygen concentration (F₁O₂ 15%) under normobaric conditions, during which O₂ saturation was monitored by pulse oximeter; electrocardiogram, blood pressure and symptoms were also monitored. O₂ saturation of 85% (PaO₂ 50 mm Hg) was considered a positive test. In the 8 cases (17%) with a positive test, 5 had chronic obstructive pulmonary disease and 3 had cardiovascular and/or combined heart-lung disease.

We calculated predicted O₂ partial pressure in altitude (PaO₂ ALT) and compared it to actual results in the 8 patients with a positive HIT. In 5, use of the predicted formula would have under-diagnosed the hypoxemia that developed during the HIT. Thus, the results of the HIT changed treatment strategy in these patients. We recommend that patients with positive tests use O₂ (2LPM or 4LPM) during flight.

HIT is practical and of potential benefit in the objective assessment of patients with various degrees of heart, lung or combined heart-lung disease. Clinicians should be aware of the relative risk of hypoxia during flight in such patients, and of the value of HIT in identifying them, leading to increase in its use.

Adult articular cartilage lacks the capacity for self-repair. The limiting factor appears to be the inability of chondrocytes to proliferate while embedded in the extracellular matrix typical of hyaline cartilage. Cartilage defects larger than 1 cm² change articular biomechanics and lead to eventual osteoarth-ritis and joint destruction.

During the past decade, several competing techniques have evolved to stimulate articular cartilage repair. Small lesions can be successfully treated by either micro-fracture or osteochondral cylinder grafting. The latter technique allows immediate weight bearing but leads to damage of previously uninvolved areas of articular cartilage, which limits its application to lesions of less than 2 cm².

When the damaged area is more extensive, grafting of autologous chondrocytes should be considered. First a diagnostic arthroscopy is performed to assess the damaged area and a small cartilage biopsy is taken. 6 weeks later, arthrotomy and chondrocyte transplantation are performed. In the interval, the antologous chondrocytes have expanded by 2 to 3 orders of magnitude. Our experience to date includes 10 cases with follow-up of 6 months to 5 years. Preoperative complaints of crepitation and locking disappear. There is functional improvement and pain reduction of approximately 50%. This procedure, currently limited to patients under 55 years of age with limited damage to an articular surface, for the first time allows reconstruction of damaged articular areas without resorting to allografts.

Accepting and forgiving attitudes to the use of cannabis in its various forms, such as marijuana or hashish, are not justified, as they may result in dangerous mental health consequences.

A theoretical framework for this opinion is provided, including information on the various forms of cannabis available. Case studies presented exemplify possible complications resulting from use of cannabis or its derivatives.

Lately an increasing number of physicians are asked to diagnose and treat physical and mental disorders caused by alcohol abuse, a phenomena which had been quite rare in Israel until recently.

Early diagnosis and efficient treatment are essential for the management of alcohol-dependent patients. Primary care physicians and hospital personnel should be more alert to the growing numbers of alcohol abusers and to their appropriate diagnosis and treatment. This article describes and summarizes the symptoms of alcohol withdrawal in general, and alcoholic delirium in particular. Problems in diagnosis and treatment are illustrated by typical cases, pointing out early clinical warning signs and suggesting some treatment guidelines.

Laparoscopic cholecystectomy is the "gold standard" in treating cholelithiasis. Stones are frequently lost in the peritoneal cavity during the procedure, but "missing stones" have been regarded as insignificant. However, there is accumulating evidence that untreated "lost" stones may cause complications even years after operation.

We present a 65-year-old woman who presented with vague complaints, anemia and an elevated ESR. CT scan showed an infiltrating process in extra-abdominal muscles compatible with sarcoma. At operation, 2.5 years after previous laparoscopic cholecystectomy, an abscess was found which contained biliary stones. Because of their small size they were not visible on CT scan. We discuss the possible ways of handling "falling stones."

Interest in, and use of alternative medicine has increased in the past few years in Israel. Still, little is known about the extent to which it is utilized, the more common treatments, patterns of use, and its influence on the conventional primary care system. We surveyed a kibbutz community to determine prevalence and patterns of use of alternative medicine and satisfaction with the outcome. The entire kibbutz population was asked to fill out a questionnaire (parents answered for their children). They were questioned as to their use of alternative medicine in the previous 5 years, types and dates of treatment, duration of treatment, and whether it had helped.

Of 1044 subjects, 830 responded (79.5%). 16.4% had used alternative medicine at least once in the previous 5 years. Of these, more than a 1/4 were treated by 2 or more types of alternative therapy. About 2/3 of those responding were women. Most had muscle-skeletal (36%), upper respiratory and/or atopic problems (19.3%). The most common treatments were homeopathy (31%) and acupuncture (20%). In approximately 2/3, the treatment was considered helpful, and either solved the problems or gave long-lasting improvement. 70% of those who used alternative medicine were treated within the previous 15 months and about 40% within the previous 3 months. The use of alternative medicine is increasing and it is now includein standard medical services. Most of those who used alternative therapy felt is hadhelped.

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.

Ecstasy is a stimulant used mainly by youngsters to get 'high.' There are few reports of acute injury of the liver due to ecstasy. We describe a 37-year-old woman who presented with the clinical picture of recurrent hepatitis following ingestion of the drug. After several months she developed liver cirrhosis shown by biopsy and CT scanning. This case emphasizes the potential danger of ecstasy. Every patient with hepatitis of unknown origin must be questioned about ingestion of the drug.
