The article presents the case of a 37-year-old patient with acute leukemia. Four days before the appearance of acute symptoms, the patient manifested unspecific prodromes, with headache, coughing, and tiredness. Within 18 hours, he then presented the complete picture of acute leukemia, with multiple brain hemorrhages, diffused leukemic infiltration of all organs, and the typical alterations in blood picture. Eighteen hours after the first specific symptoms, the patient died of therapy-resistant cerebral pressure.

A 38-year-old man was admitted to the hospital with complaints of persistent fever up to 40 degrees C, arthralgias, headache and a nonproductive cough. The white-cell count was within the normal range but was markedly shifted to the left and demonstrated toxic granulations. Sonographic examination of the abdomen revealed a slight enlargement of the spleen. A nonspecific reactive hepatitis which was clinically asymptomatic was detected by laboratory evaluation. Diagnosis of an acute Q fever was made by demonstration of antibodies against C. burnetii. Following therapy with doxycycline, the patient became afebrile within 48 hours.

Two hours after ingestion of improperly cooked meat a German tourist in Tunisia showed coughing, hoarseness, dysphagia, anosmia, frontal headache and epistaxis. At the same time a papular non-itching exanthema developed. The nasal discharge contained nymphs of Linguatula serrata. Histological examination of the papules revealed tissue eosinophilia and 'flame figures'. Nasopharyngeal and skin signs subsided spontaneously within 10 days. The possible role of major basic protein in the pathogenesis of nasopharyngeal linguatulosis is discussed.

The knowledge and opinions of health professionals of Botucatu about the frequency and severity of thirteen symptoms and signs of diseases were studied with a view to comparing then with the opinions of Botucatu's urban population. Four hundred and thirty-five active health professionals (physicians, nurses, nurse aides, health workers (orderlies) and others were interviewed. Most of them were women, with ages ranging from 25 to 44. The health workers (orderlies) were the most numerous category. In general, the last five symptoms included in the form: bloody sputum, vaginal bleeding, breast lump, seizures and bloody urine, were considered less frequent and more serious as compared with the first eight symptoms: shortness of breath, fever, weakness, back pain (backache), chest pain, headache, cough and diarrhoea. Among the categories, the physicians differed from the other categories in less frequently attributing high scores to frequency and severity. The clinicians gave more value to these two factors than the surgeons for almost all symptoms. The comparison with the opinions of the laymen interviewed showed similar tendencies although the laymen regarded frequency and severity as more significant.

In a multicenter study in general practice, the tolerability and safety of ramipril alone and in combination with a low dose of furosemide were assessed in moderate hypertension. After a placebo run-in period involving 770 patients, 661 were included in the active treatment period and received ramipril alone (2.5-5 mg/day). After 6 weeks, the nonresponders entered in a double-blind period and they received daily ramipril 10 mg or ramipril 5 mg in combination with furosemide 20 mg. In this hypertensive population, the adverse events more commonly reported were headache, cough, dizziness, asthenia, cramps diarrhea and nausea, but not all these events were related to ramipril. There was seemingly a relation between cough prevalence and rampiril dosage; an increased incidence was also observed during the outbreaks of flu-syndrome in our country. 38 patients discontinued the active treatment due to non-serious adverse events, mainly cough, dizziness or diarrhea. No serious adverse drug reaction was observed. Laboratory data (blood cells count, electrolytes, serum creatinine, fasting blood glucose, apolipoproteins AI and B) remained most commonly unaffected. In moderate hypertension in general practice, this study confirms that ramipril is well tolerated, especially with regard to the class effects of the angiotensin converting enzyme inhibitors.

The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage and administration of adenosine in the treatment of episodes of paroxysmal supraventricular trachycardia (PSVT) are reviewed. Adenosine is an endogenous adenine nucleoside that markedly decreases heart rate and prolongs atrioventricular (AV)-nodal conduction. Adenosine is rapidly cleared from plasma by the cellular elements of the blood and by vascular endothelial cells and subjected to enzymatic metabolism. The drug has a half-life of 0.6 to 10 seconds. In noncomparative clinical trials, adenosine terminated 85% to 100% of induced or spontaneous episodes of PSVT involving the AV node in the reentrant circuit. In patients with arrhythmias that do not involve the AV node in the reentrant circuit, adenosine produces AV block and does not restore sinus rhythm. Prospective, randomized trials comparing adenosine with verapamil in adults have not yet been performed. The adverse effects of adenosine include flushing, dyspnea, headache, cough, chest pain, sinus bradycardia, atrial fibrillation, ventricular arrhythmias, and various degrees of AV block. Because of the short half-life of adenosine, these effects are transient and well tolerated. The initial dose of adenosine in treating acute PSVT is 6 mg given by rapid i.v. bolus injection, followed in one to two minutes by up to two additional 12-mg boluses if necessary. Adenosine has been found to be effective in terminating PSVT and thus offers an alternative to verapamil. Prospective, randomized trials comparing adenosine with verapamil are needed to definitively establish adenosine's role in the therapy of PSVT.

The long acting angiotensin-converting enzyme inhibitor enalapril was compared with the calcium channel blocker nifedipine as sustained-release formulation in 136 patients with mild to moderate hypertension. This multicentre study was carried out in a double-blind, double-dummy fashion by 28 cardiologists in private practice. After a 2-week placebo period, patients were randomly allocated to 2 treatment groups; the first group received enalapril 20 mg daily (n = 68), and the second group received sustained-release nifedipine 20 mg twice daily (n = 68). The duration of treatment was 12 weeks. In both groups, hydrochlorothiazide 25 mg was added at week 4 if diastolic blood pressure remained greater than 90 mm Hg. At week 8, if the target diastolic pressure of less than 90 mm Hg was not achieved, the dosage of hydrochlorothiazide was increased to 50mg. The clinical characteristics of the patients in each group were comparable. After 4 weeks of treatment, the reduction in supine diastolic blood pressure was similar in both groups (12.1 mm Hg in the enalapril group vs 10.3 mm Hg in the nifedipine group). Moreover, although the difference between the groups was more noticeable after 12 weeks of treatment (16.3 vs 13.9 mm Hg, respectively), it did not reach significance. The number of patients experiencing clinical adverse effects was significantly greater in the nifedipine group than in the enalapril group [33 (48.5%) vs 18 (26.5%), respectively]. The most common complaints of patients administered nifedipine included swollen ankles, flushing and headaches, whereas complaints in the enalapril group included cough, asthenia, and epigastralgia. Three patients were withdrawn from the study because of side effects in the enalapril group and 10 were withdrawn from the nifedipine group. These results indicate that enalapril and sustained-release nifedipine are equally effective in controlling mild to moderate hypertension. However, enalapril was much better tolerated in this study.

Phenylpropanolamine (PPA) is contained in about 106 products, over half of which are available over-the-counter (OTC). Most are cough/cold remedies; nine are OTC diet aids. More than nine million Americans were using OTC diet aids in 1981, making PPA the fifth most used drug in the United States, responsible for over $200 million in revenues. The safety of PPA remains controversial. Although most controlled studies indicate minimal pressor effects with recommended doses, adverse drug reactions (ADRs) continue to be documented. Since 1965, 142 ADRs have been reported in 85 studies, 69% of these in North America. Many such cases may go unrecognized. About two thirds of all ADRs occurred in females and in patients under 30. Of ADRs attributed to legitimately sold PPA products, 85% occurred after consumption of OTC products versus only 15% after prescription drugs. The PPA product often contained combination ingredients, or PPA was consumed along with additional drugs. An overdose of PPA was taken in about a third of the cases. After ingestion of non-overdose amounts, 82% of the ADRs were severe. The most frequent side effects involved symptoms compatible with acute hypertension, with severe headache the most common complaint. Twenty-four intracranial hemorrhages, eight seizures, and eight deaths (most due to stroke) were associated with PPA ingestion. We have summarized these data in an effort to alert clinicians to the prevalence of usage of PPA products and the potential for adverse effects. In patients who present with elevated blood pressure or signs of acute hypertension, especially hypertensive encephalopathy of undetermined origin, we recommend inquiry about recent ingestion of PPA-containing diet aids and cough/cold products and suggest having such patients remain upright rather than supine.

Recently there has been extensive development of orally active angiotensin converting enzyme (ACE) inhibitors in addition to those already marketed, for example, captopril, enalapril, lisinopril and ramipril. It was initially thought that ACE inhibitors were likely to be most useful as antihypertensive agents in conditions in which circulating renin and angiotensin II were elevated. However, it is now clear that they can also lower arterial pressure when plasma renin is not high. In addition, they have beneficial effects in cardiac failure. Thus, captopril, enalapril, lisinopril and ramipril can be used in the treatment of mild to moderate hypertension either alone or in conjunction with diuretics or calcium antagonists. Broadly speaking, efficacy appears to be similar to that of beta-blockers or diuretics. Unfortunately, however, there are no long term studies comparing one ACE inhibitor with another or with other classes of antihypertensive agents. Furthermore, there are no prognostic studies which show that use of ACE inhibitors reduces morbidity or mortality in hypertension. Many new ACE inhibitors are undergoing clinical assessment, including alacepril, cilazapril, fosenopril, perindopril, quinapril and ramipril. The drugs vary, in that some exist in the active form whereas others are prodrugs which are converted to the active agent following absorption. In addition they each possess one of several ligands, for example, carboxyl, phosphinyl or sulfhydryl groups, and so vary in their affinity for ACE. Although many of these agents are renally excreted, a small number are metabolised via the liver (e.g. quinapril and spirapril) and this may prove advantageous in the presence of renal impairment. In common with captopril and enalapril, the new ACE inhibitors inhibit the renin-angiotensin system and initial results suggest that they are effective in lowering blood pressure in essential hypertension. Furthermore, they reduce systemic vascular resistance in the absence of a reflex tachycardia. There are a number of adverse effects which are attributable to the pharmacological mechanism of the ACE inhibitors as a group; these include hypotension, particularly in patients with high renin levels, prior diuretic use, renal impairment or in the elderly. Additional adverse effects may relate to chemical structure. The high incidence of adverse effects noted in early studies related to excess dosage and to the presence of a sulfhydryl group, which the more recently developed ACE inhibitors lack. The adverse effects most commonly reported with established and new ACE inhibitors include headache and fatigue, cough, skin rashes, hypotension and diarrhoea. As a group, ACE inhibitors have an acceptable but not negligible adverse effect burden.(ABSTRACT TRUNCATED AT 400 WORDS)

Sixty-eight patients infected with human immunodeficiency virus (HIV) and Cryptococcus neoformans who presented to three major medical centers in New Orleans, Louisiana, were studied retrospectively. In patients with meningitis the most common presenting symptoms were fever and headache. Those without central nervous system involvement generally had an isolated pulmonary infection due to C. neoformans and presented with cough and dyspnea. CSF parameters were abnormal in 41% of patients, and the India ink preparation was positive in 88% of patients with cultures of CSF positive for C. neoformans. The overall median survival time for the 47 patients who died was 5 months, with a range of 0-22 months. Of the 27 patients who received maintenance therapy with amphotericin B, two (7%) relapsed. The only factors found to be associated with a poor prognosis were abnormal computed tomography of the head and altered mental status on presentation. C. neoformans infections in HIV-infected patients remain difficult to treat and have a poor prognosis.
