From November 1990 to February 1991 was had, in the Emergency Unit of Clinical University Hospital San Carlos, Madrid, 13 documented cases of intoxication due to Carbon Monoxide (CO), in patients with unspecific cephalalgia and asthenia and a possible CO source (total 19 affected people living together, because some of them did not came to hospital to consult). We consider that CO intoxication shall be always be beared in mind when doing the diagnosis at the Emergency Unit, especially during winter months, and that appropriate resources should be available to perform promptyl the analytical confirmation.

Intranasal desmopressin represents the treatment of choice in Central Diabetes Insipidus. Nevertheless, this route of administration bears some practical disadvantage, linked to either difficult delivering technique, or the status of nasal mucose. The antidiuretic effectiveness of oral desmopressin has been recently demonstrated, both in experimental animals and in man. In our study we compared oral vs. intranasal desmopressin efficacy in 13 patients affected by Central Diabetes Insipidus. The results show that the peroral administration of Desmopressin at a mean dose of 500-600 micrograms/die determines an antidiuretic effect comparable to that of intranasal route, without affecting body weight, arterial pressure and chemical analysis. Side effects, generally limited to the first week of treatment, were described (nausea, vomiting, headache, dizziness [corrected], bitter taste, epygastralgia, asthenia, epystassis), inducing 4/13 patients to withdrawal the trial.

Infection with the tick-borne Borrelia burgdorferi can lead to a variety of neurologic symptoms, the most frequent being a radicular pain syndrome due to meningitis. General symptoms such as asthenia or headache are also frequent, however, and serious neurologic complications such as dementia or spastic paresis may occur. At an early stage, Borrelia infections can be easily treated with antibiotics, which makes it important to recognize the symptoms and make the correct diagnosis. A common feature of borreliosis is facial palsy, and in the article is described the case of a 14 year-old boy with borreliosis and bilateral facial palsy. The frequency of facial palsy from borreliosis is probably high. The authors discuss the indications for performing lumber puncture in patients with apparent idiopathic facial palsy (Bell's palsy).

The acceptability of perindopril in the long-term treatment of patients with mild to severe essential hypertension was assessed in a large European multicenter trial including 856 patients. Diastolic blood pressure (DBP) at inclusion was 95-125 mm Hg after 1 month of placebo. Normalization of blood pressure was defined as a DBP less than or equal to 90 mm Hg. Treatment was started with perindopril 4 mg once daily and increased when necessary to 8 mg daily. If DBP was not controlled, a second drug (hydrochlorothiazide) and finally a third drug were added. After 1 year of treatment in all 690 evaluable patients, supine systolic and diastolic blood pressure decreased by 29 mm Hg (from 172 +/- 1 to 143 +/- 1 mm Hg, p less than 0.001) and 19 mm Hg (from 105 +/- 1 to 86 +/- 1 mm Hg, p less than 0.001), respectively. Perindopril monotherapy normalized blood pressure in 55% of patients and total percentage of normalization was 78%. The overall incidence of withdrawals for side effects was 6.8%, the most common side effect being cough (2.2%). The most frequent complaints reported were cough (7.0%), headache (5.6%), asthenia (5.1%), mood and/or sleep disturbance (5.1%), and dizziness (3.2%). The small changes observed in hematologic and biochemical parameters were not clinically relevant.

The new alpha 1-blocker alfuzosin was compared with propranolol as monotherapy for hypertension in a double-blind, parallel group study of 8-week duration in 40 patients with essential hypertension. The patients (11 males, 29 females; mean age 47.8 +/- 2.2 years in the alfuzosin group and 46.6 +/- 2.4 years in the propranolol group) randomly received either alfuzosin from 2.5 mg b.i.d. up to 10 mg b.i.d. or propranolol from 40 mg b.i.d. up to 160 mg b.i.d. according to an individualized dose-titration schedule. The two groups were comparable with respect to disease history, cardiovascular risk factors, concomitant diseases, previous treatments and end-placebo blood pressure and heart rate values. Four patients did not complete the study, two patients in the alfuzosin group: one patient because of postural hypotension and the second one because of breast cancer; and two patients in the propranolol group: one patient for inefficacy and the second one lost to follow-up. At the end of the 8-week trial the mean daily doses were 12.2 +/- 0.61 mg and 196 +/- 9.82 mg for alfuzosin and propranolol, respectively. The antihypertensive effects of the two drugs were comparable. Upright and supine blood pressures decreased significantly with both treatments from the second week on (P less than 0.001 for all BP values). At the end of the 8-week double-blind trial, 83% of alfuzosin patients and 67% of propranolol patients were normalized. The two treatments differed significantly with respect to their effect on heart rate. Alfuzosin did not induce marked changes in heart rate: only a slight increase was observed. In contrast, propranolol caused bradycardia, more marked in the upright position. Palpitations, headache, asthenia and orthostatic hypotension were reported in the alfuzosin group. Asthenia and decreased libido were reported in the propranolol group. These data prove that alfuzosin has antihypertensive effects equivalent to propranolol and it is an interesting agent for the therapy of essential hypertension. It can be used as a first agent at doses between 5 and 20 mg/day with satisfactory therapeutic response and without relevant side-effects.

This randomized, placebo-controlled, double-blind study was performed to evaluate the efficacy and safety of once-a-day terazosin (10 mg/day) in ambulatory patients (n = 57) with benign prostatic hyperplasia (BPH). After a 4-week placebo lead-in and a 24-week treatment period with terazosin (both single-blind), 30 patients who responded to terazosin were randomly assigned to either the terazosin or placebo treatment group for 12 weeks. During the single-blind treatment period, the peak urine flow rate increased 54% from a baseline average of 7.76 ml/sec to 11.92 ml/sec after terazosin; the mean flow rate increased 55% from a baseline of 4.90 ml/sec to 7.59 ml/sec; and the residual volume decreased 56% from 93.1 ml to 40.7 ml. The mean obstructive symptom score, irritative symptom score and physician's global assessment score improved by 68%, 34% and 27%, respectively. All these changes were significant (P less than 0.05) when compared to baseline values. During the double-blind period, the improvement in all the variables was sustained in the terazosin group but not in the placebo group. Peak and mean urinary flow rates, and physician's global assessment showed significant (P less than or equal to 0.05) differences at the end of the double-blind period. Adverse events occurred only during the single-blind period. The most frequent were headache (n = 6), asthenia (n = 3), and hypotension (n = 3). In summary, terazosin administered once-a-day improved the obstructive and irritative symptoms of BPH, urine flow rates and residual volume. Terazosin was well tolerated.

The rationale for using alpha blockade to treat benign prostatic hyperplasia (BPH) is based on the physiology and pharmacology of prostate smooth muscle. Approximately 20% of the area density of the prostate adenoma is smooth muscle. In vitro isometric tension studies have demonstrated that the contractile properties of the human prostate adenoma are mediated primarily by alpha 1 adrenoceptors. Alpha blockers presumably decrease the resistance along the prostatic urethra by relaxing the smooth muscle component of the prostate. Over the past 14 years, at least 16 clinical trials have confirmed the efficacy of alpha blockade in the treatment of BPH. The primary advantage of terazosin over all other commercially available alpha blockers is that its longer half-life allows for a once-daily dosage regimen. Two Phase II studies conducted in the United States, a multicenter dose titration randomized withdrawal study and the author's personal experience with terazosin, are summarized in this report. Overall, the peak urinary flow rate increased 50% and the mean urinary flow rate increased 46% following terazosin therapy. The mean obstructive and irritative scores improved 67% and 35%, respectively. The adverse reactions occurring with an incidence greater than 5% included headache (10%), asthenia (7%), and dizziness (14%). All adverse events were reversible on termination of therapy. The preliminary experiences with alpha blockers for the treatment of BPH has been very encouraging. Yet, the definitive role of alpha blockade in BPH awaits the reporting of multicenter, randomized placebo-controlled studies.

A total of 555 hypertensive patients took part in a 2-year multicenter, open-label study to determine the efficacy, tolerance, and safety of long-term therapy with ramipril. In the beginning, all patients were to receive 5 mg of ramipril/day. The dosage was then adjusted in accordance with response to treatment and ranged from 1.25-20 mg of ramipril daily. Of these patients, 129 also received 25 mg of hydrochlorothiazide daily at some point during the trial. To evaluate whether tolerance to ramipril developed during long-term treatment, a subgroup of 202 patients was analyzed for efficacy maintenance. Prior to enrolling in the 2-year study, these patients had received ramipril monotherapy in a short-term, double-blind study and had been classified as responders, i.e., their diastolic blood pressure had been maintained at less than or equal to 90 mm Hg. At the end of 104 weeks of treatment, 45.9% of patients were on 2.5 mg of ramipril alone and 43.6% were on 5 mg of ramipril alone. Only four patients required the addition of 25 mg of hydrochlorothiazide. No clinically important changes occurred, and kidney function was well maintained. The most frequently reported adverse events excluding intercurrent illnesses were dizziness/vertigo (6%), asthenia (4%), nausea (3%), headache (2%), and abdominal pain, gastrointestinal disorder, rash, and increased cough (1% each). Ramipril was safe, effective, and well tolerated in the long-term treatment of patients with mild-to-moderate essential hypertension.

In this study, the tolerability and safety of ramipril, as monotherapy and in combination with a low dose of furosemide, were assessed in patients with mild-to-moderate hypertension in general practice. After a placebo run-in phase, patients received ramipril as monotherapy in a dose of 2.5 to 5 mg daily for 6 weeks. Nonresponders (diastolic blood pressure greater than 90 mm Hg) entered a double-blind treatment period, and received either 10 mg of ramipril daily, or 5 mg of ramipril in combination with 20 mg of furosemide daily. The tolerability of the study medication was assessed by reported adverse events, and by monitoring blood cell count, electrolytes, serum creatinine, fasting blood glucose, and apolipoproteins AI and B. Of a total of 770 patients who entered the placebo run-in phase, 661 patients were enrolled in the first active treatment period. The most commonly reported adverse events were headache, cough, dizziness, asthenia, cramps, diarrhea, and nausea, but not all of these events were related to ramipril treatment. A total of 38 patients discontinued active treatment due to nonserious adverse events, mainly cough, dizziness, or diarrhea. There appeared to be a relationship between the prevalence of cough and ramipril dosage; however, an increased incidence of cough was also observed during outbreaks of influenza in France. There were no significant changes in laboratory variables during the study.

Fluoxetine is a highly specific serotonin reuptake inhibitor. In studies that used a dose of 60 mg once daily, fluoxetine-treated patients consistently had greater weight loss than placebo-treated patients. In six double-blind, placebo-controlled studies of 6-8 wk duration, mean weight changes on fluoxetine were approximately 0.5 kg/wk. Longer term studies have shown maximum mean weight loss to occur at 12-20 wk of therapy. Studies have consistently shown improvements in indices of glycemic control as well as weight loss in obese diabetic patients. Safety analysis has been performed on data from 3491 obese patients in controlled clinical trials of up to 52 wk duration. Adverse events with an incidence of greater than 5%, which were reported significantly more frequently by fluoxetine-treated patients, were headache, asthenia, nausea, diarrhea, somnolence, insomnia, nervousness, sweating, and tremor. Fluoxetine is effective, well tolerated, and safe in the treatment of obesity and obese diabetics.
