The antianginal efficacy of a transdermal therapeutic delivery system for nitroglycerin (TNG) was compared with that of placebo in a double-blind crossover study. Twenty-five patients with stable angina pectoris were evaluated. The transdermal system delivered 5 mg of nitroglycerin over a 24-hour period and was applied once every 48 hours. Treadmill exercise testing (Bruce protocol) was done 48 hours after the patch was applied in the first phase of the crossover and at the conclusion of the second phase of the crossover, 48 hours after the final dose of the second treatment. Exercise performance was significantly improved (P less than 0.05, analysis of covariance) with TNG as compared with placebo, as were frequency of episodes of angina and nitroglycerin consumption (P less than 0.05, analysis of variance). The incidence of mild-to-moderate headache in patients was greater during treatment with TNG (20%) than during placebo treatment (6.7%). Four cases of mild transient dermatitis and occasional reports of dizziness, lightheadedness, and nausea were noted.

Human brucellosis, a multisystem disease which may mimic other conditions, has a low incidence in childhood and the diagnosis may easily be missed. Over a 7-month period 9 children with brucellosis presented to the Department of Paediatrics and Child Health, Tygerberg Hospital. Six of the children had consumed unpasteurized milk. The main presenting symptoms were fever, fatigue, headache, myalgia and haematuria. Clinical signs included lymphadenopathy (3), nasopharyngitis (2), features of lower respiratory tract infection (2), splenomegaly (2) and pyrexia (1). The diagnosis was made on the basis of a positive serological titre (> 1:160) for Brucella abortus. The prozone phenomenon was encountered in 6 cases; however, the Coombs test confirmed the diagnosis in these cases. Children under 7 years were treated with co-trimoxazole and rifampicin and those over 7 years with tetracycline and rifampicin, for at least 6 weeks. No relapses were detected on follow-up.

The hyperimmunoglobulinemia D and periodic fever (hyper-IgD) syndrome is typified by recurrent febrile attacks with abdominal distress, joint involvement (arthralgias/arthritis), headache, skin lesions, and an elevated serum IgD level (> 100 U/ml). This familial disorder has been diagnosed in 56 subjects worldwide. As the hyper-IgD syndrome resembles familial Mediterranean fever, one could speculate that both result from mutations in the same gene. The gene causing familial Mediterranean fever (MEF) has been located on chromosome 16p. We have studied 10 families with 19 affected and 28 non-affected subjects. The clinical findings and IgD determinations from these families are compatible with autosomal recessive inheritance. Using highly polymorphic markers surrounding the MEF gene, only negative Lod scores were obtained, whereas haplotype analysis excluded this locus as the cause of the hyper-IgD syndrome. In addition, no indication for linkage was obtained with markers from other candidate gene regions on chromosomes 17q and 14q.

The efficacy and safety of extended-release isosorbide mononitrate tablets were evaluated in patients with stable effort angina. In a double-blind study, 313 patients with stable effort-induced angina were randomized to receive placebo or extended-release isosorbide mononitrate: 30, 60, 120 or 240 mg once daily in the morning. Serial exercise testing was performed using the standard Bruce treadmill protocol on days 1, 7, 14, 28 and 42 immediately before morning drug administration, and 4 and 12 hours after administration. After initial dosing, all groups that received extended-release isosorbide mononitrate had significant (p < 0.01) increases in mean total exercise time of approximately 30 to 50 seconds in relation to placebo 4 and 12 hours after administration. On day 42, mean changes from baseline in total exercise time of patients who received 120 or 240 mg of extended-release isosorbide mononitrate exceeded placebo by approximately 50 to 60 seconds 4 hours after dosing (p < 0.01), and by 30 to 35 seconds 12 hours after dosing (p < or = 0.05). No significant difference was detected between responses to extended-release isosorbide mononitrate and placebo 24 hours after administration (i.e., immediately before the next dose). Thus, there was neither significant activity nor demonstrable rebound of effort-induced angina (zero-hour effect) at the end of the dosing interval. Transient headache was the most prevalent adverse experience. Extended-release isosorbide mononitrate (120 and 240 mg administered orally once daily) significantly prolonged exercise time to development of moderate effort-induced angina 4 and 12 hours after dosing during long-term therapy, without development of nitrate tolerance.(ABSTRACT TRUNCATED AT 250 WORDS)

We report on 10 patients with acute renal involvement in Hantaan virus infection observed at the Department of Nephrology, Faculty of Medicine, Skopje, Republic of Macedonia, during a period of 3 years (October 1987-July 1990). Eight patients were male and 2 were female, aged 37.5 +/- 4.8 years. The diagnosis of Hantaan virus infection was proven by an indirect immunofluorescent and ELISA test with a significant increase of the titer after a week to ranges from 1:512 to 1:2,048. Percutaneous renal biopsy was performed in 3 cases using standard procedures for optical and immunofluorescent microscopy. Fever, weakness, headache, conjunctival injection, hematuria, and lumbar pain were clinical features all patients had in common. Complete anuria was noted in 7 out of 10 and oliguria in the other 3 of the 10 cases with serum levels of creatinine 967 +/- 152.6 mumol/L. Other following laboratory findings were leukocytosis in 10 out of 10 patients, with neutrophylia, and reduction of serum sodium and potassium in 8 out of 10, and a decrease in serum complement C3 in 3 out of 10 patients. Percutaneous renal biopsy confirmed interstitionephritis in 2 out of 3 biopsied patients and acute diffuse proliferative glomerulonephritis in the third. Interstitial mononuclear infiltration with dominant T cells proven with monoclonal antisera (direct immunoperoxidase method) was present in all 3 cases. The outcome of the disease was good in 8 of the 10 patients with a development of polyuric phase and complete recovery of renal function later. One patient with interstitial lesions on biopsy developed chronic renal failure, and the other with a concomitant brucellosis died during the polyuric phase of the disease.

One hundred four Saudi patients with brucellosis who were admitted to Abha General Hospital in the Asir region of southern Saudi Arabia were studied. All the patients had Brucella melitensis infection; 61.5% were females while 38.5% were males. Their mean age was 32 years. Most of the patients (61.5%) lived in the lowland (Tihama) and the majority were shepherds (84.6%). The most common presenting symptoms were fever (100%), sweating (96.2%), headache (76.9%), joint pains (76.9%), and backache (73.1%). Physical findings included fever (96.2%), hepatomegaly (46.2%), splenomegaly (42.3%), tenderness over the spine (30.8%), arthritis (26.9%), and lymphadenopathy (19.2%). Mild anemia, leukopenia, and relative lymphocytosis were common. A history of raw milk ingestion was an important factor in disease transmission (84.6%), followed by close animal contact (73%) and raw liver consumption (63.3%). The study shows the effectiveness of several drug combinations in the treatment of brucellosis and the low relapse rate if the treatment is prolonged for not less than six weeks.

Monthly disease summary sheets from 1986-1992 of 60 dispensaries, clinics and hospitals in Narok district, Kenya were reviewed for the occurrence of brucellosis and other diseases with "flu-like symptoms". Diseases with these symptoms accounted for about 52% of the 1,037,875 cases reported for the time period. These were classified as malaria (79.3%), rheumatism (7.1%), PUO (2.4%), and brucellosis (0.8%). Brucellosis was diagnosed by a positive Rose Bengal (RB) test routinely conducted in seven out of the 60 health units. In these units, 55% of flu-like cases were classified as malaria and 21.2% as brucellosis. Individual case records of patients at four dispensaries using the RB test during 1991-92 were assessed for specific predictor symptoms. For 625 RB tested patients, a positive test result was associated with joint pain, headache, and the combinations of joint pain with headache and lameness with headache. A logistic regression model correctly predicted the RB test result in 62.3% of the time. For the 465 patients examined by the blood smear examination, identification of malaria parasites was associated with, headache, joint pain and combinations of emesis with pale mucous membranes. This regression model correctly predicted positive results 67.2% of the time. Both models indicate that selected clinical predictors represented significantly increased odds of being positive to the respective tests. However, for both diseases, clinical signs alone appear insufficient for reliable diagnosis and differentiation probably due to resemblance in symptomatology between these two and other diseases.

The effect of extended-release isosorbide mononitrate (ER-ISMN) on exercise tolerance 1 hour after dosing was compared with that of placebo in a multicenter, randomized, double-blind study of 151 patients with stable effort-induced angina. During a 9- to 24-day placebo run-in, patients underwent Bruce protocol baseline exercise tolerance tests, after which they received ER-ISMN or placebo for 5 days. ER-ISMN patients took 60 mg each morning for the first 4 days and 120 mg on the morning of the fifth day. One hour after dosing, ER-ISMN patients had a significantly greater increase in total exercise time (days 1 to 4: 5 +/- 53 seconds; day 5: 53 +/- 58 seconds) than the placebo-treated patients (days 1 to 4: 14 +/- 37 seconds; day 5: 21 +/- 48) (p <0.001). The times to development of angina and 1-mm ST-segment depression were significantly longer in the ER-ISMN group than in the placebo group. The difference between the groups in mean time to onset of angina was 34 seconds after the 60-mg dose (p = 0.004) and 49 seconds after the 120-mg dose (p <0.001). The mean time to development of a 1-mm ST-segment depression was 51 and 61 seconds longer after the 60-mg and 120-mg ER-ISMN doses, respectively, than after placebo (p <0.001). Treatment-related adverse events were reported in 37% (28 of 75) and 7% (5 of 76) of patients in the ER-ISMN and placebo groups, respectively. As expected, headache was more frequent in the ER-ISMN group than in the placebo group (28% and 1%, respectively). The effects of ER-ISMN (60 mg and 120 mg) are clinically evident 1 hour after dosing, resulting in better exercise tolerance in patients with angina pectoris.

In order to verify the frequency of human brucellosis among a TB suspected population, a study was conducted on the basis of sero-diagnosis of a total of 229 blood samples from TB suspected patients. Serological tests carried out were slide and semi-quantitative agglutination tests. Of the tested samples, 44 (19.21%) were SAT positive and of these, 28 (12.23%) were positive for the semiquantitative agglutination test. Twelve (42.86%) had a brucella titer of 1:80; 14 (50%) had a brucella titer of 1:160 and 2 (7.14%) had a titer of 1:320. The majority of patients positive for brucellosis, exhibiting sero-agglutination titers ranging between 1:40 and 1:320, were of rural background. However, 35.72% persons positive for brucella antibody with titer of 1:160 were from urban localities. Fever (84.48%), headache/dizziness (71.43%) and weakness/fatigue (46.43%) were the most common presenting symptoms among the brucellosis positive patients. The frequency of brucellosis among these TB suspected patients was found to be higher in women (73.91%), as compared to men (52.38%).
