Two hundred patients clinically certified as suffering from anxiety state were investigated with a view to understanding the clinical manifestation of the condition in Nigeria. We found that 67 symptoms were manifested by those patients, but only 15 symptoms were presented by about 10% of the sample. These common symptoms were: frequent headaches, difficulty in falling asleep, flushing, difficulty in concentrating, rapid or irregular heart beating, weakness, hot flashes, dizziness, feeling of something crawling in the head, heaviness of the head, nervousness, poor appetite, poor sight, nightmares, and chest pain. The five major precipitating factors were physical ailments, studying and examinations, use of drugs, psychological phenomona, pregnancy and childbirth, in decreasing order of magnitude. The most vulnerable age group was between 18 and 23 years old. The first born children account for the highest number of anxiety patients, but as the number of siblings increases, the vulnerability of the last-born increases. Anxiety neurosis as seen here is predominantly a problem of single males and females with secondary school education.

Rhodamine B is a red colored dye that is used in cosmetic products. We report a case of 17 patients who were exposed to aerosolized Rhodamine B inside a maintenance shop. The mean duration of exposure was 26 minutes (range 2-65). Sixteen of the patients (94%) complained of acute symptoms including: burning of the eyes (82%), excessive tearing (47%), nasal burning (41%), nasal itching (35%), chest pain/tightness (35%), rhinorhea (29%), cough (29%), dyspnea (29%), burning of the throat (24%), burning/pruritic skin (24%), chest burning (12%), headache (6%), and nausea (6%). All of the patients had resolution of their symptoms within 24 hours (less than 4 hours in 63%). Acute exposure to Rhodamine B resulted in transient mucous membrane and skin irritation without evidence of serious sequellae.

Anxiety is the fifth most common clinical diagnosis in the primary care setting. Panic disorder, a severe episodic form of anxiety, has been found to occur in approximately 6% of primary care patients. These patients often selectively focus on one of the frightening autonomic symptoms and are frequently misdiagnosed. The three most common presentations of panic disorder in the medical setting are cardiac symptoms (chest pain, tachycardia), neurologic symptoms (headache, dizziness/vertigo, syncope), and gastrointestinal symptoms, especially epigastric distress. The presentation of cardiac symptoms by patients with panic disorder is especially likely to lead to expensive and potentially iatrogenic medical testing. Hypertension and peptic ulcer are the most commonly associated medical diagnoses in patients with panic disorder. Major depression, alcohol abuse, simple phobias, and posttraumatic stress disorder are the most frequently associated psychiatric diagnoses. Psychopharmacologic treatment of panic disorder has been demonstrated to be highly effective in double-blind, placebo-controlled studies. Effective psychopharmacologic agents include the tricyclic antidepressants (notably imipramine and desipramine), the monoamine oxidase inhibitors (phenelzine), and the high-potency benzodiazepines (alprazolam).

Twenty-four patients with stable exercise-induced angina pectoris entered a double-blind cross-over study. Isosorbide-5-mononitrate (5-ISMN) 60 mg in a controlled release formulation (Durules) given once daily was compared with identical placebo. The exercise tolerance was determined by bicycle ergometry before and 3 h after a single dose of 5-ISMN and following one week's treatment with 5-ISMN and placebo. Nineteen patients completed the study. Exercise tolerance until the onset of chest pain and until 1 mm ST segment depression increased significantly 3 h after dose. The same increase was seen both after a single dose and the same dose under steady-state conditions. No increase was seen with placebo. The heart rate and systolic blood pressure reactions in the standing position were less pronounced 3 h after dose in steady-state than after a single dose of 5-ISMN. Headache was the only bothersome side-effect reported. The study demonstrates that 60 mg 5-ISMN in a Durules formulation given once daily has a significant anti-anginal effect and that tolerance does not develop.

Prescription of oral contraceptives is reviewed by giving practical tips on the absolute contraindications, timing of the first dose, dose of estrogen, choice of type of progestin, reasons for changing the combination, and a list of benefits of oral contraceptives. The major risk in taking orals is cardiovascular disease, but actual risks are clustered in subsets of women. Those at high risk are women over 45, smokers over 35, and smokers of any age with cardiovascular risk factors. Generally women should start with a 30 or 35 mcg estrogen combined pill, and perhaps consider taking a higher estrogen dose if they experience breakthrough bleeding or amenorrhea. The 1st cycle can be started at any time up to 6 days after Cycle Day 1 or after spontaneous or induced abortion. Women taking bromocriptine should also begin contraception soon after delivery. Signs of potential major complications are abdominal pain, chest pain or dyspnea, headache or neurologic symptoms, visual or speech problems, or leg pain or weakness. Benefits of oral contraception include menstrual regulation, decreased menstrual flow, prevention of functional ovarian cysts, protection against ovarian and endometrial cancer by half, against benign breast disease, and possibly against pelvic inflammatory disease.

During the past 2 years, 102 patients were treated for unstable angina pectoris (AP) in our department. Fifteen of them had recurrent chest pain at rest despite treatment with various anti-anginal agents, or prolonged chest pain unresponsive to sublingual nitroglycerin; they received intravenous isosorbide dinitrate (ISDN) infusion. A rapid bolus injection of 2 to 6 mg followed by an infusion of 2 to 5 mg/hr was given to 10 patients with acute chest pain, and 5 patients, who were free of chest pain at the time, but had repeated episodes of angina in the past 24 hours, were given ISDN infusion without a bolus injection. Chest pain disappeared completely in 13 patients, but recurred in 2 of them when the dose was tapered. Two other patients experienced recurrent chest pain during ISDN infusion, and additional boluses were given. The hospital course was uneventful in 11 patients. Four patients who had recurrent anginal attacks underwent emergency coronary cineangiography under intraaortic ballon counterpulsation and aorto-coronary bypass surgery. There were no hospital deaths, no one had subsequent acute myocardial infarctions, and only 2 patients had mild to moderate headache as a side effect. Although the patient population is small, intravenous ISDN infusion is useful in the management of severe unstable AP.

This pilot study was designed to investigate the relationship between perceived stress, self-esteem and "functional" pain in young adolescents with and without chronic disease. Twenty children with chronic disease and 15 without who were seen in a pediatric outpatient clinic completed a symptom survey, the Piers-Harris Self-Concept Survey, and Lewis's Feel-Bad Scale. Adolescents with significant self-reported complaints of abdominal pain, chest pain, and headaches (without documented organic cause) scored higher on the Feel-Bad scale (p less than 0.002) and lower on the self-concept scale (p less than 0.02) than those without functional complaints. Patients with chronic disease scored higher on the self-esteem measure (61 +/- 14 versus 48 +/- 14, p less than 0.01) and lower on the stress measure (80 +/- 40 versus 120 +/- 54, p less than 0.02) than those without a chronic disease. These findings of lower stress and higher self-esteem in adolescents with chronic illness were unexpected. Possible explanations are discussed.

Severe adverse reactions to intravenous immune serum globulin occurred repeatedly in four of 10 hypogammaglobulinemic patients. Treatment-limiting symptoms included fever, chills, headache, hypertension, and chest pain. Pretreatment of patients with hydrocortisone immediately prior to infusion prevented subsequent adverse reactions and permitted these patients to receive immune serum globulin intravenously.

Seventy nine cases of sporadic, community acquired legionnaires' disease have been reviewed. Annual and seasonal variation in incidence was noted. The mean age of the patients was 53 years and 50 (63%) were male. Pre-existing chronic diseases were present in only 23 (29%), including two patients receiving immunosuppressive treatment. Common symptoms included unproductive cough, dyspnoea, chest pain, headache, confusion, nausea, vomiting, and diarrhoea. Respiratory symptoms were absent, however, in 17 (22%). Localising chest signs were present in 74 (95%) cases. Frequent laboratory findings included lymphopenia, high erythrocyte sedimentation rate, hyponatraemia, raised urea and creatinine concentrations, abnormal liver function, hypophosphataemia, hypoalbuminaemia, proteinuria, and haematuria. Thirteen patients died (16%), including nine of 20 who received assisted ventilation. The mortality rate in patients treated with erythromycin (11%) was lower than in those who received other antibiotics (23%), but this difference was not statistically significant. Of the features noted on admission, only a high plasma urea concentration was significantly associated with death. Sporadic community acquired legionnaires' disease is a not uncommon disorder, which with appropriate treatment has a prognosis similar to that of other forms of community acquired pneumonia.

Cardiac and noncardiac side effects were studied in 293 consecutive patients referred for nonexercise stress thallium imaging with intravenous dipyridamole. Six minutes after the initiation of infusion, there was a mean 9-beat/min increase in heart rate and a mean 12-mm Hg decrease in systolic blood pressure. The largest increase in heart rate exceeded 20 beats/min in only 13% of patients and the largest decrease in systolic blood pressure exceeded 20 mm Hg in 31%. Noncardiac side effects were headache (11%), lightheadedness or dizziness (5%) and nausea (4%). Only 9 patients required intravenous aminophylline for relief of noncardiac side effects: severe headache in 7 and nausea in 2. Cardiac side effects included chest pain in 76 patients (26%), of whom 70% were given aminophylline for relief of symptoms. Sixty patients (20%) had ischemic ST-segment depression and 56 (19%) had arrhythmias (ventricular in 50 and atrial in 6). There were no deaths, myocardial infarctions or sustained arrhythmias due to dipyridamole administration. Among 62 patients also undergoing cardiac catheterization, side effects except for arrhythmias were unrelated to the number of vessels with coronary artery disease. Intravenous dipyridamole is safe for nonexercise stress testing and has few serious side effects. However, the possibility of ischemia requires careful selection of patients and monitoring of vital signs and the electrocardiogram during the test.
