Dermatology Dept., Tel Aviv-Sourasky Medical Center

Various plants induce dermatitis in man. There have been only a few published cases of contact dermatitis caused by Agave americana (AA).

We report intentional exposure to AA in a soldier seeking sick leave, and review our previously reported cases. Treatment with oral antihistamines and topical saline compresses resulted in subsidence of the systemic symptoms within 24h and regression of cutaneous manifestations in 7-10 days.

Physicians should be alert to the possibility of self-inflicted contact dermatitis induced by exposure to plants, especially to A. americana. Systemic signs may accompany the cutaneous lesions.

Sublingual Immunotherapy for Allergic Diseases

David Nelken

Medical Building, Sprinzak St., Tel Aviv

4 patients suffering from severe pollinosis and/or allergic rhinitis, with or without asthma, were treated as follows: 30 minutes before breakfast the vaccine was dropped sublingually and retained for 2-3 minutes before being swallowed. It was a commercial preparation of allergen, diluted 50% w/v in glycerin.

This stock solution was then diluted in physiological saline containing 0.05% human albumin and kept refrigerated in a dark glass bottle for up to 4 weeks. Of the first dilution which contained 10 Au/ml, 1 drop was given on day 1 and 1 drop more each day until days 5 to 17, when 5 drops were given daily. Then 1000 and then 2500 Au/ml were given sequentially in the same manner, and finally 5000 was given for up to 2 years. A maintenance dose of 3 drops of 5000 Au/ml twice weekly was then prescribed.

41 patients showed striking clinical improvement after about 6 months of treatment. A definite reduction in the use of other medications was achieved in all. Sublingual immunotherapy is practically free of unwanted side effects and easy to self-administer at home.

To establish the specificity of sublingual immunotherapy, patients who had severe allergic symptoms to one pollen allergen causing symptoms in the spring and to a second in the autumn, were first immunized sublingually against a single allergen. A year later, after symptoms due to this allergen had subsided, and if symptoms caused by the second allergen had not improved, immunization against the second allergen was started.

Sublingual immunotherapy acts by increasing mucosal antibodies at the site of entry of the allergen into the respiratory tract. It is a safe and practical procedure with results comparable to subcutaneous allergy injections.

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.

2 cases of malaria in family practice are described in a 26- and a 50-year-old woman. Both probably could have been prevented had common chemoprophylactic drugs been taken. The risk of malaria is greater than the risk of possible side-effects of the drugs commonly used by travelers for prevention. Family physicians must be aware of the possibility of malaria in young people with fever, especially those who have travelled to equatorial areas and special attention should be given to encourage chemoprophylaxis.

Dept. of Medicine and Hypertension, Wolfson Medical Center, Holon

The efficacy, safety and side-effects of treatment with losartan (Ocsaar) was studied for the first time in Israel in a large group of patients with mild to moderate hypertension in several community clinics. The 421 patients (51% men) aged 30-86 years (mean 58.6) received 50 mg of losartan daily, increased when necessary to 100 mg, and/or a second antihypertensive drug was given. After 4 weeks blood pressure was normalized in 344 and after 12 weeks in 363. Side-effects were minimal and treatment was effective in all age groups.

Brucellosis is contracted from domestic animals. Poor hygiene, primitive animal breeding methods and traditional food preparation are the main contributory factors. We describe an intersectoral program for controlling brucellosis in Taibe, an Arab town in Israel, which had a particularly high incidence of the disease in 1992 and 1993.

At the beginning of 1994 the Israel Ministry of Health and the Community Pediatric Center of Taibe established a community-based program for controlling brucellosis in Taibe. It included an intensive public health education campaign and periodic examination and vaccination of animals. Physicians, veterinarians, nurses, school officials and health inspectors were recruited for this purpose. Residents' awareness of brucellosis was determined before and after the study.

After intervention, the incidence of the disease sharply declined from 176.6 and 175.0/100,000 in 1992 and 1993 respectively, to 5.7, 10.4 and 2.5/100,000 in 1994, 1995 and 1996, respectively, (odds-ratio 24.44; p<00000). Residents' awareness of brucellosis and preventive measures were significantly increased by the end of the study. We conclude that intersectoral collaboration is an important tool for controlling brucellosis.

Massive splenomegaly is defined as a spleen weighing about 10 times normal weight. We describe a 36-year-old man who had huge splenomegaly and secondary pancytopenia simulating malignant lymphoma for about 3 months. Splenectomy was necessary because of the suspicion of hematologic malignancy, especially isolated lymphoma of the spleen, and pain and mechanical abdominal disturbances.

On operation, the spleen was 25 cm long and weighed 250 g. There was florid, reactive follicular lymphoid hyperplasia. Immunohistochemical staining with CD-20(L26), CD-45Ro(UCHL), bcl-2 oncoprotein (Dakopatts), EBV (anti-EBV mol weight 60 KD, Dakopatts) was consistent with reaction to EBV infection and not with follicular lymphoma. Lack of PCR amplification using DNA extracted from paraffin-embedded splenic tissue indicated absence of a monoclonal B cell population carrying rearranged immunoglobulin genes. The lymphocytic population was proven polyclonal by the negative results of PCR for the bcl-2 gene rearrangement. EBV seroconversion from high titer antibodies of anti-EBV-VCA-IgM to negative, and from negative EBNA to positive was consistent with an apparent primary EBV infection.

We have not found on computerized search a previous report of reactive follicular splenic hyperplasia to EBV infection causing huge splenomegaly, with or without EBV-induced infectious mononucleosis.

The new police car flashing-light device (930 Heliobe Lightbar) has recently been implicated as potentially epileptogenic. We exposed 30 epileptic patients, 30 nonepileptic patients who suffered from headache and 15 normal volunteers to this light source. All had routine EEGs with standard intermittent photic stimulation, followed by 3-minute stimulation with the Lightbar. In none were either seizures or EEG changes induced. In 1 epileptic spike-and-wave activity induced by standard photic stimulation was enhanced with the Lightbar.

We could not confirm that the Lightbar is epileptogenic.

After 3-5 years of continuous use of 1-dopa preparations for Parkinson's disease, 25%-50% of patients develop side-effects such as the "on-off" phenomenon and involuntary movements that markedly impair function. One cause of these manifestations is evidently a disturbance in the absorption of 1-dopa.

We attempted to avoid this problem by using subcutaneous injections. Apomorphine is a rapid-acting dopamine agonist which causes a return from "off" to "on" within minutes.

We present the results of a trial of subcutaneous injections of apomorphine in 22 Parkinsonian patients (12 males, 10 females) with severe motor fluctuations. During 5 days prior to the apomorphine all received Motilium (domperidone, 60 mg/d) to prevent nausea and vomiting. All were hospitalized initially to determine optimal dosage and to teach them the technique of self-injection.

2 to 4 mg of apomorphine were injected 1 to 3 times daily for 2 to 12 months. In 17 patients (80%) "off" periods were reduced without significant side-effects. Apomorphine seems to be effective, tolerable treatment for shortening 1-dopa induced "off" periods.

7 cases of listeriosis were diagnosed here between 1988-1997 (6 in last 3 years), or 2.94/100,000 admissions. 2 elderly patients suffered from meningitis and 2 pregnant women presented with premature contractions, 1 of whom delivered a premature, infected baby. 2 other patients had fever and gastroenteritis.

Listeria monocytogenes was isolated from blood in 4, CSF in 2 and the placenta in 1. It was isolated from those with bacterial meningitis. All patients recovered. Both increased awareness for prevention and better diagnosis are essential to reduce morbidity from this unusual pathogen.

Prevalence of hepatitis G virus (HGV) infection in the general western population ranges from 0.2-1.5%. In high-risk groups, such as patients with chronic liver disease, hematologic disorders and drug addicts, prevalence is as high as 10%-15%. Dialysis patients have increased rates of HGV infection (6%-50%).

We evaluated prevalence of HGV infection among dialysis patients, and the association between HGV infection and hepatitis C virus (HCV) infection. Serum samples were screened for HGV infection by RT-PCR. Screening for HCV infection was performed by an EIA test and confirmed by RIBA and RT-PCR for HCV. Sera were also tested for HBV markers.

The study group included all 78 hemodialysis patients and 7 of the 12 peritoneal dialysis patients in our unit during September to November 1997. 4 (5.2%) were HGV-positive but none were peritoneal dialysis patients. 1 of the 12 HCV-positives was also infected with HGV. HGV infection was not associated with duration of dialysis, number of blood transfusions or levels of transaminases.

Prevalence of HGV infection among our hemodialysis patients was low (5.2%), but higher than reported for the general population. Prevalence of HGV/HCV infection in hemodialysis patients was low and unrelated to duration of dialysis, number of blood transfusions and levels of transaminases.

Cryptococcal meningitis (CM) is common in the immunocompromised (especially due to AIDS), but also occurs in immunocompetent subjects. CM can complicate cryptococcal pneumonia (CP) not only in the immunocompromised but also in the immunocompetent. We describe a healthy 26-year-old man who developed a prolonged lung infection. Diagnosis of cryptococcal pneumonia was established from bronchoscopic washings. He recovered spontaneously, so no antifungal treatment was given.

4 months later he was admitted with cryptococcal meningitis and was treated successfully with amphotericin B. An extensive immunologic study revealed no abnormalities. Since CM can complicate cryptococcal pneumonia, it is recommended that patients with CP be followed, even if recovery is apparently complete.

Resistance to antibiotics is considered the main reason for failure to eradicate Helicobacter pylori (HP). Resistance rates are different in developed and developing countries and are not known for Israel. We studied HP resistance rates in 40 patients who underwent esophagoduodenoscopy for various indications and were found to have gastric HP colonies.

Sensitivity was determined by E-test, using clarythromycin, amoxycillin, clindamycin, erythromycin and metronidazole. The resistance rate for metronidazole was up to 67% but that for clindamycin was only 10%. HP was very sensitive to both macrolide antibiotics, erythromycin and clarythromycin.

Equine Rhodococcus Equi Pneumonia: First Report in Israel and its Significance for Man

Rhodococcus equi is an important pathogen in young horses. In recent years it has been increasingly recognized as an opportunistic infectious agent in patients with immune deficiency. The increase in recognized cases may be related to the increased prevalence of AIDS. However, more cases may have been recognized lately due to increased awareness of the pathogenicity of this bacterium. Based on medical reports, there appears to be an association between Rhodococcus equi infections and exposure to animals, horses in particular.

During the past year, 2 cases of rhodococcus pneumonia were diagnosed in foals in Israel. This information deserves the attention of the local medical community because of the zoonotic potential of Rhodococcus equi and the danger of its becoming more common. The climate in Israel is conducive to its growth and viability and since it flourishes in an environment with horses, the significant growth in our equine industry in recent years may contribute to an increase in Rhodococcus infections.
