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).

A retrospective study of 55 patients with panic disorder referred for psychiatric consultation by primary care physicians is presented. Eighty-nine percent of the patients initially presented with one or two somatic complaints, and misdiagnosis often continued for months or years. The three most common presentations were cardiac symptoms (chest pain, tachycardia, irregular heart beat), gastrointestinal symptoms (especially epigastric distress), and neurologic symptoms (headache, dizziness/vertigo, syncope, or paresthesias). Eighty-one percent of patients had a presenting pain complaint. Hypertension and peptic ulcer were the most common medical diagnoses, and depression and alcoholism the most frequently associated psychiatric diagnoses.

The overall incidence of adverse drug reactions following ampicillin and amoxicillin administration to 439 and 169 indoor patients of All India Institute of Medical Sciences, New Delhi were 19.13% and 15.5% respectively. Ampicillin produced diarrhoea (7.74%), nausea and vomiting (7.74%) anorexia (5.46%) headache (4.10%) and allergic reactions (2.9%). With amoxicillin, anorexia was observed in 4.79%, epigastric distress in 5.9% headache in 6.58%, coating of tongue in 8.98% and dizziness in 1.79% of patients. Intramuscular route of administration of ampicillin produced least ADRs. Females were more susceptible to adverse reactions of ampicillin and males to amoxicillin. Incidence of ADRs by these two aminopenicillins is less than that reported from abroad.

Hemodynamic syncope is caused by an impediment to a necessary increase of the cardiac output; therefore, hemodynamic syncopes most often occur during or shortly after exercise. However, a syncope at rest does not exclude a hemodynamic cause. Moreover, arrhythmias which may directly lead to syncope or accentuate the hemodynamic impediment are often present in cardiac diseases causing hemodynamic syncope. Hemodynamic syncopes are responsible for 2 to 3% of all syncopes leading to medical evaluation. Of these, more than half are caused by aortic stenosis and about one quarter by pulmonary embolism. Other reasons are rare. Hypertrophic cardiomyopathy is more often associated with arrhythmic than with hemodynamic syncope. Syncope in primary pulmonary hypertension is often preceded by dizziness, epigastric distress and faintness. Since the medical therapy may lead to hemodynamic deterioration, it must be started under invasive observation. Primary tumors of the heart are rare; secondary cardiac neoplasms are 6 to 40 times more common. Myxoma is the most common primary tumor of the heart. It is important to promptly undertake surgery in order to improve prognosis. Various other diseases may provoke hemodynamic syncope; however, other symptoms are by far more common.
