Several examples of the use of vital statistics in drug epidemiology are described. The death rates for asthma remained stable from about 1860-1960 in the UK, about 0.5/100,000. In 1961 the rates began to rise, and after 1967 they declined; in the 1970s the rates almost approached pre-epidemic levels. The rates were found to vary with the use of isoproterenol-containing nebulizers. Investigations into the relationship between thromboembolism pulmonary embolism, and myocardial infarction and oral contraceptive (OC) usage showed an increase in death rates beginning after the introduction of OCs in 1960-61 in women at risk. Subacute myelo-optic neuropathy was an unexplained disease until Japanese investigators linked its occurrence to ingestion of the halogenated hydroxyquinoline drugs used to treat nonspecific gastroenteritis; seasonal outbreaks of the disease were linked to seasonal gastroenteritis. Animal experiments conclusively linked the drug to the disease. A Swedish report implicated the antihypertensive drug methyldopa as a possible cause of cancer of the biliary ducts. Links between thalidomide and phocomelia, saccharin or cyclamates and bladder cancer, diethylstilbestrol and vaginal cancer, and estrogens and endometrial cancer are discussed. Drug-monitoring systems, the collection of vital statistics and observations by clinicians all contribute to understanding drug-induced disease. Changes in disease incidence or emergency of new syndromes in areas where certain drugs are heavily used should be compared to areas where they are seldom used.

We examined the effect of the emergency response on medical and public health problems during the 1991 Gulf War in Israel. On the first day of the conflict, the number of deaths from suffocation, asphyxiation, aspiration, myocardial infarction, cardiac arrest, and cerebrovascular accident increased abruptly, as did the number of sudden deaths associated with the use of tight-fitting masks with filters in sealed rooms. Much of the excess risk for death from cardiorespiratory complications during the first alert may have been a consequence of its duration (140 minutes). Mass evacuation and concrete buildings are believed to have kept the death toll from trauma down, and mask use may have protected against facial and upper-airway injuries. Falls and hip fractures, airway irritation from exposure to bleach, carbon monoxide intoxication from open kerosene heaters in sealed rooms, and self-injection with atropine syringes were also noted. A measles epidemic and increased death rates from automobile crashes were other preventable causes of death. Protection against biological warfare was limited to surveillance of trends for pneumonia and gastroenteritis. Emergency planners failed to anticipate the need for better mask fit, hands-on training in the use of masks, and special guidelines for older persons to prevent deaths from suffocation and other cardiovascular-respiratory problems in the first minutes of use. If masks are to be distributed as a protection against chemical warfare, a simpler model including the use of shrouds for whole-body skin protection might help avoid cardiorespiratory complications. Public health problems not adequately dealt with in the predisaster period are apt to emerge with greater severity during a crisis.

Experience of acute medical, surgical conditions, and clinical procedures of undergraduate students were assessed via a questionnaire survey during the final week of the 1993/1998 programme at the School of Medical Sciences, Univestiti Sains Malaysia. Individual performances were assessed by a scoring system. One hundred and twenty four students responded, (response rate 97%). More than 90% had seen myocardial infarction, cerebrovascular accident, pneumonia, respiratory distress, gastroenteritis, coma, and snake bite. Less than 33% had witnessed acute psychosis, diabetic ketoacidosis, acute hepatic failure, status epilepticus, near drowning, hypertensive encephalopathy, acute haemolysis or child abuse.Acute surgical/obstetrics cases, seen by >90% students, included fracture of long bones, head injury, acute abdominal pain, malpresentation and foetal distress. Less than 33% had observed epistaxis, sudden loss of vision, peritonitis or burns. Among operations only herniorrhaphy, Caesarian section, internal fixation of fracture and cataract extraction were seen by >80% students. The main deficits in clinical procedures are in rectal and vaginal examinations, urine collection and microscopic examinations. The performance of individual students, assessed by a scoring system, showed 15 students had unacceptably low scores (<149/230, 50%), 37 had good scores (>181.4/230, 70%) and 5 had superior scores (197.6/230, 80%).

The varied clinical manifestations and management of 14 male patients with delirium tremens (DT) have been studied. Eight patients were initially hospitalised for diseases unrelated to ethanol abuse i.e. 2 each for gun shot wound, myocardial infarction and stroke, and one each for pneumonia and gastroenteritis. One patient was going through withdrawal because of prodrome of viral hepatitis before he was hospitalised for uncontrolled agitation and delirium. Two known cases of mild essential hypertension on dietary therapy reported for agitation, abnormal behaviour, a single episode of tonic clonic seizure and hypertensive encephalopathy as they could not/did not get alcohol for 3 days. Three patients presented denovo with DT without concomitant illness. The other features besides delirium and hallucinations were tremulousness in 10, tachycardia in 12, fever in 3, diaphoresis in 2 and tonic clonic seizures in 4 patients. The symptoms fluctuated markedly at short intervals and 2 patients did not have any features of sympathetic overactivity. Altered hepatic biochemical parameters and ketonuria with normal blood sugar were noted in 4 and one patients respectively. Other biochemical parameters including serum electrolytes were normal. CT scan brain done for 5 patients revealed subdural haematoma in one. Cerebro spinal fluid (CSF) and EEG findings were noncontributory. All made good recovery with heavy doses of intravenous vitamin B complex, glucose and oral benzodiazepine. Short course of haloperidol was used in 2 patients. Two patients developed pancreatitis during follow up. All patients made complete recovery, and 8 patients have been followed for 8 to 12 months without relapse. The reason for hospitalisation in such cases is often unrelated to alcohol abuse; hence a detailed history of alcoholism is mandatory to identify those at risk as well as for prompt treatment and decreasing the mortality.

An advanced degree of body potassium deficit may produce striking changes in the electrocardiogram (ECG). These changes can result in incidental findings on the 12-lead ECG or precipitate potentially life-threatening dysrhythmias. Although usually readily recognized, at times these abnormalities may be confused with myocardial ischemia. The object was to report a case of severe hypokalemia mimicking myocardial ischemia. A 33-year-old, previously healthy man, presented to the Emergency Department (ED) with a progressive weakness and chest discomfort. The electrocardiogram showed a marked ST-segment depression in leads II, III, aVF, V1-V6. The initial diagnosis was non ST-elevation myocardial infarction. Echocardiography was normal and troponin levels were within normal limits. A more detailed history revealed that the patient had an episode of acute gastroenteritis with diarrhea and vomiting. Serum chemistries were notable for a potassium concentration of 1,8 mmol per liter. With aggressive electrolyte correction, the ECG abnormalities reverted as potassium levels normalized. Hypokalemia induced ST-segment depression may simulate myocardial ischemia. The differential diagnosis might be difficult, especially in the cases when ST changes are accompanied with chest discomfort.

Salmonella infection predominantly causes four clinical syndromes: enteric fever, gastroenteritis, bacteremia, and asymptomatic carrier state. Salmonella osteomyelitis is an extremely rare manifestation of salmonella infection except in children with hemoglobinopathies. Salmonella osteomyelitis has been reported to mostly affect the diaphysis of long bones and lumbar spine. Here, we describe a case of salmonella osteomyelitis of the right 6th rib in a 74-year-old woman who presented with breast pain, swelling, high fever and local heat. Her medical history showed myocardial infarction; namely, at the age of 71, the patient had undergone the drug-eluting stent placement in the left anterior descending artery. A computed tomography (CT) scan at the first visit to another hospital showed a mass in the chest that invaded the ribs. 18F-fluorodeoxyglucose-positron emission tomography-computed tomography imaging showed a lesion suspected to be a mammary malignant tumor. A needle biopsy revealed mesenchymal cells and suspected mammary sarcoma. However, the osteomyelitis of the rib was diagnosed when pyogenic tissue was observed during an open biopsy. The bacterial culture examination identified Salmonella enterica. Surgical drainage and antibiotic treatment were performed. Importantly, there was no evidence for any underlying disease that could lead to an immunocompromised status of the patient. To our knowledge, this is the first report of salmonella osteomyelitis of the rib presenting in an older female that required differentiation from a mammary tumor. Clinicians should consider rib osteomyelitis when they find swelling and local heat in the female's breast tissue and detect no cancerous tissue.
