Stevens-Johnson syndrome is an acute, inflammatory eruption of the skin and mucous membranes often associated with drug ingestion. A forty-five-year-old woman showed symptoms consistent with Stevens-Johnson syndrome two days after indapamide therapy was begun for the treatment of hypertension. Initial manifestations consisted of headaches, sore throat, cough, and symptoms of conjunctival injection, including redness and swelling. Approximately two weeks later, the patient noted skin eruptions involving the conjunctiva, lips, face, neck, trunk, and extremities. She was treated with cool compresses, antiseptics, ophthalmic antibiotics and steroids, and oral prednisone. Symptoms began to resolve approximately eight days after indapamide was discontinued and treatment was begun. Although rare, Stevens-Johnson syndrome should be considered in the differential diagnosis of a patient with a history of indapamide ingestion who presents with malaise, fever, and skin eruptions.

A 71-year-old man was admitted to the Wake Forest University/Baptist Hospital Medical Center on February 1, 1989, with pharyngitis and a cutaneous eruption that began that day. The past history was significant for a diagnosis of chronic lymphocytic leukemia (CLL) made in 1984, and for longstanding hypertension, severe coronary artery disease, and prostatic hypertrophy. The patient had required no therapy for his CLL until August, 1988, when he developed hemolytic anemia and was treated with oral chlorambucil, 4 mg/day, and a tapering course of prednisone. By December, 1988, the prednisone therapy had been discontinued, but the patient required hospital admission for pneumococcal pneumonia, which responded well to intravenous antibiotic therapy. One day prior to the current admission the patient complained of persistent fevers, sore throat, productive cough, and headache. He noted a new cutaneous eruption on the day of admission in February, 1989. The past history was positive for occasional herpes stomatitis. The patient did not know if he had previously been infected with varicella. Skin examination revealed multiple (greater than 20), single, and grouped vesicles in a generalized distribution involving the bilateral trunk, head, neck, arms, and legs. The heaviest involvement was on the right posterior auricular area and on the neck. A Tzanck preparation obtained from an early lesion was positive for multinucleated giant cells. Viral culture was negative at 24 hours and at 1 week. A skin biopsy of an early vesicular lesion was performed and revealed intraepidermal vesicles with acantholysis and giant cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Although cyclosporin is effective in immunosuppression following organ transplantation and in the treatment of psoriasis, its use is limited by its side-effects, notably impaired renal function and hypertension. As SDZ IMM 125, a new derivative of the cyclosporin family, showed considerable immunosuppressive activity in experimental studies, with less effect on renal function, it was considered a potential successor to cyclosporin for both indications. In this multicentre, double-blind, placebo-controlled study, the efficacy and tolerability of 40, 100, 200 and 400 mg SDZ IMM 125 daily were studied in 59 patients with psoriasis. Patients were followed for a period of 5 weeks (4 weeks treatment, and 1 week post-treatment observation). A dose-dependent effect of SDZ IMM 125 was observed. A significant correlation was found between the dose of SDZ IMM 125 and changes in the sum of severity scores of three indicator plaques. There was a significant decrease in the body surface area affected by psoriasis in the 400-mg group (P < or = 0.01), whereas a decrease of the global psoriasis severity was observed in the 200-mg (P < or = 0.01) and the 400-mg groups (P < or = 0.001). No serious adverse events occurred during the 4 weeks of treatment. Three patients discontinued treatment because of adverse events (one sore throat, two influenza). Clinical adverse events were similar to those reported with cyclosporin, the most frequent being gastrointestinal disturbances. Estimation of renal function indices showed that increases from baseline values were dose-dependent, and appeared to be similar to those seen with cyclosporin.(ABSTRACT TRUNCATED AT 250 WORDS)

Captopril 12.5 mg twice daily was initially administered given to a woman with chronic renal failure and hypertension. Three weeks later, she developed chills, high fever and sore throat. Hemogram showed severe neutropenia; the white cell count showed 600/cu mm; bone marrow aspirate and biopsy revealed a paucity of myeloid series. Antineutrophil antibody was not detected in the serum. The neutrophil counts returned to normal after captopril was discontinued two weeks later. We recommend that the peripheral white blood cell count in patients whom captopril is prescribed must be carefully monitored in the first three months, particularly in those with impaired renal function.

1. Bradykinin and related kinins may act on four types of receptors designated as B1, B2, B3 and B4. It seems that the B2 receptors are most commonly found in various vascular and non-vascular smooth muscles, whereas B1 receptors are formed in vitro during trauma, and injury, and are found in bone tissues. 2. These BK receptors are involved in the regulations of various physiological and pathological processes. 3. The mode of kinin actions are based upon the interactions between the kinin and their specific receptors, which can lead to activation of several second-messenger systems. 4. Recently, numerous BK receptors antagonists have been synthesized with prime aim to treat diseases caused by excessive kinin production. 5. These diseases are RA, inflammatory diseases of the bowel, asthma, rhinitis and sore throat, allergic reactions, pain, inflammatory skin disorders, endotoxin and anaphylactic shock and coronary heart diseases. 6. On the other hand, BK receptor antagonists could be contraindicated in hypertension, since these drugs may antagonize the antihypertensive therapy and/or may trigger the hypertensive crisis. 7. It is worth suggesting that the BK receptor agonists might be useful antihypertensive drugs.

Four hundred and three teenage secondary school students (50.6% males) from two girls' and two boys' Nairobi City Schools, selected by stratified sampling, were screened to determine the prevalence of proteinuria, haematuria, nitrituria and hypertension. Nine students (2.2%) had significant proteinuria while 14 (3.5%) had microscopic haematuria. Two students had combined proteinuria and haematuria. There was no statistically significant difference in the prevalence of proteinuria and/or haematuria between the sexes. Other urinary abnormalities detected were leucocyturia in 14(3.5%) and nitrites in four (1%). Leucocyturia was commonner in females (p = 0.001). Cloudy urinary appearance was significantly associated with the presence of leucocyturia (p = 0.0028) and proteinuria (p = 0.0276). Neither personal history of recurrent sore throat and skin infections nor family history of hypertension, diabetes mellitus or kidney disease was significantly associated with proteinuria or haematuria. Blood pressure tended to increase with age. Mean systolic and diastolic blood pressures were significantly higher in boys than girls in the age group 15-18 years (P < 0.001). Of the 397 students whose blood pressures were measured, four (1%) were found to be hypertensive. Weight and body mass index were strong positive correlates of blood pressure. The prevalence of proteinuria, haematuria, other urinary abnormalities and hypertension ranges between 1% and 3.5% among teenage secondary school children. The majority are asymptomatic and have no significant associations. It is recommended that routine urinalysis and blood pressure measurements should be part of the school health service so as to identify asymptomatic students who require close monitoring and/or intervention.

A four-year old boy was admitted to the hospital due to acute thrombocytopenic purpura. Three days later he developed edema, hematuria and hypertension. The diagnosis of acute poststreptococcal glomerulonephritis was based upon the evidence of previous sore throat, hypocomplementemia and increased antistreptolysin O titer. Renal biopsy was contraindicated due to throbocytopenia. An extensive work-up was done to exclude mebranoproliferative glomerulonephritis and systemic diseases such as hemolytic uremic syndrome or systemic lupus erythematosus. The clinical outcome of the nephritis and thrombocytopenia was excellent in respect to both conditions. To the best of our knowledge concurrent occurrence of acute thrombocytopenic purpura and poststreptococcal glomerulonephritis is very rare; there are only four similar cases reported in the literature. A careful work-up and follow-up are mandatory to exclude systemic disease.

Laryngoscopy and tracheal intubation produce intense noxious stimuli and are associated with an adrenergic response that can be deleterious in patients with concomitant diseases. Illuminating stylets effectively aid blind intubation by lighting the trachea, and using such devices has been associated with lower incidences of sore throat, dysphonia, and adverse hemodynamic events in comparison with rigid laryngoscopy. We report the case of a female patient with a catecholamine-secreting vagal paraganglioma. She developed multiple hypertensive episodes that were difficult to control during surgical resection of the tumor. It was decided to perform orotracheal intubation with a Light Wand (Vital Signs, Inc., Totowa, NJ, USA) to avoid oropharyngeal stimulation and to attenuate the hypertension and arrhythmias associated with laryngoscopy in such patients. The procedure was carried out without difficulty on the first attempt, in spite of tracheal displacement. The maximum increases in blood pressure and heart rate were observed 1 minute after intubation and were less than 30% of basal levels. We believe that using this light wand while intubating this patient helped keep the expected hemodynamic response to a minimum during laryngoscopy.

Minoxidil is frequently used in patients with advanced renal disease who have been unresponsive to other antihypertensive agents. We describe a case of a 50-year-old man with chronic renal failure who was hospitalized complaining of a 2-week history of sore throat that had progressed to severe oral lesions and multiple pustular blisters on many sites of his body. The patient had been placed on oral minoxidil for uncontrolled hypertension one week prior to the onset of symptoms. The diagnosis of minoxidil-induced Stevens-Johnson syndrome (SJS) was established, minoxidil was discontinued and the patient subsequently improved. Although minoxidil-induced SJS is extremely rare, clinicians should be aware of this potentially severe adverse effect. This report emphasizes the importance of monitoring patients who are taking oral minoxidil for any signs or symptoms associated with SJS.

Whole blood (WB) donors are deferred for several reasons, either permanently or temporarily. In this retrospective study, we quantified the rate of and reasons for donor deferral among Turkish donors. Computer records of the last 5 years were analysed to quantify the deferral rate and reasons. Deferrals were categorized as temporary short-term (1-56 days), long-term (57-365 days) and multiple years or permanent (more than 365 days). Deferred donors were also analysed according to gender, age and education level. A total of 95 317 persons were admitted for WB donation: 89.1% of them were male donors and 59.9% were in the 30 to 49-year old age category. Rates of deferral for temporary short-term, long-term, permanent or for unknown reasons were 66, 22.5, 10 and 1.5% respectively. Female donors were deferred more frequently than male donors (25.8 vs. 13.3%, P<or= 0.0001). The deferral rates were significantly different among the different age groups (P < 0.0001). Donor education level had no effect on the deferral rates (P > 0.05). The main reason for deferral was common cold and/or sore throat or elevated temperature (20.4%) in male donors and low haemoglobin (51.6%) in female donors. Although the three uppermost reasons for deferral in women were identical for all age categories, these varied in the male group (high-risk sex partner for the younger group vs. hypertension and low haemoglobin for the older group). Although permanent and temporary deferral rates are similar between the Turkish population and western countries, leading causes vary widely.
