Frederick Akbar Mahomed was an Englishman of mixed Indian and Irish descent who made substantial contributions to the study of high blood pressure in a short professional life from 1872 to 1884. He was strongly influenced by the previous work of Richard Bright on kidney disease at his own hospital (Guy's Hospital in London) and by the contemporary pathological studies of Gull and Sutton on arteriolar changes in persons with high blood pressure. In detailed clinical studies, he separated chronic nephritis with secondary hypertension from what we now term essential hypertension. He described the constitutional basis and natural history of essential hypertension and pointed out that this disease could terminate with nephrosclerosis and renal failure. His clinical studies were done without the benefit of a sphygmomanometer but with the aid of a quantitative sphygmogram that he had initially developed while a medical student. He described characteristic features of the pressure pulse in patients with high blood pressure and in persons with arteriosclerosis consequent on aging. These pressure wave changes have recently been verified and explained. He contributed to a number of other advances in medical care, including blood transfusion and appendectomy for appendicitis. He initiated the Collective Investigation Record for the British Medical Association; this organization collected data from physicians practicing outside the hospital setting and was the precursor of modern collaborative clinical trials. Mahomed died from typhoid fever, almost certainly contracted from one of his patients, at age 35 at the height of his career.

Between 1985 and 1988, a two-phase epidemiological study was conducted at the "Ruta 100" company in Mexico City to examine the harmful effects of the working conditions on drivers of urban transport vehicles. In the first phase, five groups of nine drivers each were interviewed regarding their opinions about their working conditions and possible work-related disorders. On the basis of this information, an epidemiological survey was developed and applied using a polytypic sampling design to some 200 drivers plus two other groups of approximately the same size, one consisting of maintenance workers and the other of office workers, which served as controls. The driver group showed a high prevalence of respiratory and neuropsychiatric disorders, diarrhea, myopia, arterial hypertension, urinary disorders, hemorrhoids, hearing loss, back pain, varicose veins, peptic ulcers, diabetes, cardiopathies, abdominal hernias, and appendicitis. For arterial hypertension, hemorrhoids, nervous disorders, and psychiatric disorders the prevalence ratios of drivers/maintenance workers and drivers/administrative workers were statistically significant.

A 53-year-old normotensive man underwent an appendectomy for suppurative appendicitis with peritonitis and Escherichia coli bacteremia. On the third postoperative day, he became severely dyspneic, developed bright red blood flow from his abdominal drains, collapsed, and died. At autopsy, a ruptured intramedial dissection of the right hepatic artery was found. Hepatic artery dissections are rare, but may be associated with abdominal operation, peritonitis, hypertension, or preexisting arterial disease.

A survey was conducted of admissions to a semirural hospital for Black patients in Bophuthatswana for the period April - March of the years 1959/19610 and 1977/1978 to ascertain whether any measurable change had occurred in the disease pattern. No significant increase over the 18 years was found in the number of admissions for diabetes, appendicitis, peptic ulceration, or coronary heart disease. There was, however, an increase in the incidence of anorectal conditions and in admissions for hypertension.

With westernization of diet and lifestyle among South African Blacks, particularly urban dwellers, hitherto unknown gastro-intestinal diseases are becoming evident. Previously unreported is hiatus hernia, now a definite disease entity, although still very uncommon. At Baragwanath Hospital, Johannesburg, over 17 months in 1977-1978, 46 patients with hiatus hernia were detected from barium meal examinations on 1392 persons, i.e. 3,3%, or 0,07% of total hospital admissions of adults. The disease affected mainly middle-aged and elderly women. Prevalences of obesity, comparative physical inactivity and hypertension appeared commoner than in the general urban adult population. Just as appendicitis is a marker of westernization in young urban Blacks, hiatus hernia may be regarded as a marker in the middle-aged and elderly.

The authors observed 32448 cases of alimentary toxoinfection (AT), 96.8% of which were females. Acute surgical abdominal conditions arose in 3.6% of them: appendicitis, cholecystitis, pancreatitis. Aggravation of chronic diseases occurred in 11.6% of the patients, hypertension and cholelithiasis being most frequent. 119 patients developed myocardial infarction, 266 hypertension crisis. The occurrence of acute and chronic diseases were analyzed in relation to common pathogenetic features, role of infection, intoxication, microcirculatory disturbances and hemostatic impairment. AT are suggested as risk factors of certain diseases likely to deteriorate prognosis.

Intensive animal rearing, manipulation of crop production and food processing have altered the qualitative and quantitative balance of nutrients of foods consumed by Western society. This change, to which the physiology and biochemistry of man may not be presently adapted to, is thought to be responsible for the chronic diseases that are rampant in the Industrialised Western Countries. Agriculture production and food processing practices, dietary habits and lifestyle of the West is being fostered without any appraisal of the health implications by most developing countries. Consequently, a rising trend in the incidences of obesity, diabetes, high blood pressure, cardiovascular diseases, dental decay and appendicitis is apparent. Mediterranean countries are adopting the agriculture and food practices of northern Europe as the result of the harmonisation of European food and agriculture policy. It is predicted that the low incidence of morbidity and mortality from coronary heart disease, stroke, diabetes and breast and colon cancer of the Mediterranean countries would rise to the high northern European level in the foreseeable future. Most of these chronic diseases are lifestyle related and are preventable. This can be realised by tackling the root problem which is food production and processing practices and not by dispensing designer drugs or opening more hospital beds.

The early detection of HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets) is the basic condition for immediate therapeutic management, which mainly leads to prompt delivery. The classical symptoms despite the typical laboratory evaluation (hemolysis, elevated liver enzymes, low platelets) are epigastric or right upper quadrant pain and nausea and vomiting; the classical signs of preeclampsia (proteinuria and hypertension) may be absent in 20%. The differential diagnostic problems of HELLP syndrome arise in relation to the mimicry-symptomatic: upper abdomen pain can imitate gastroenterologic diseases (e.g. cholelithiasis, appendicitis), the elevated liver enzymes combined with hyperbilirubinemia liver diseases (e.g. viral hepatitis) and thrombocytopenia in combination with hemolytic anemia, neurological symptoms and renal failure other similar pathogenetic disorders due to the category of thrombotic microangiopathies. Regarding the common symptoms thrombocytopenia, hemolysis as well as signs of preeclampsia with or without renal failure the differentiation from various autoimmune diseases also can be difficult in special cases. Rare first manifestations and serious simultaneous diseases which can overlay the typical signs of HELLP syndrome show the variety of HELLP syndrome. Interdisciplinary detours and delay are the consequences of this differential diagnostic problems, which could imply deleterious effects on the mother and the fetus, until the final diagnosis is clear. Therefore all pregnant women with upper abdomen pain irrespective of symptoms of preeclampsia should be considered to have HELLP syndrome and immediate laboratory evaluation has to be done. If there is any doubt a interdisciplinary consultation is required!

Sixty-seven children aged 5-15 years were induced to narcosis and narcotized with diprivan. The patients were operated on for appendicitis, peritonitis, osteomyelitis, phlegmons of different localization, and craniocerebral injuries. For induction, diprivan was intravenously injected in a dose of 3-4 mg/kg. During the main narcosis (central analgesia with fentanyl in a total dose of 0.008 mg/kg/h) diprivan was infused by microjets in a dose of 6-9 mg/kg/h in combination with nitrogen oxide and oxygen in 1:1 ratio. Control group consisted of similar age-matched patients, to whom central analgesia without diprivan was administered. Respiration rate, heart rate, systolic and diastolic arterial pressure, mean arterial pressure (MAP), SaO2, and clinical course of anesthesia were examined at different stages of analgesia and surgery. During induction anesthesia the respiratory rate decreased by 27% and SaO2 decreased to 92.75 +/- 1.2% due to the specific effect of diprivan. MAP decreased by 4.8%. During the traumatic moment of surgery, respiratory rate increased by 20.1%, SaO2 was 98.25 +/- 0.24%, and heart rate increased by 22.6%. In the controls this period of surgery was associated with a more expressed reaction of the cardiovascular system, presenting as tachycardia (114.5 +/- 3.6) and increase of MAP by 10.1%. After anesthesia pain sensitivity returned earlier, due to which tachycardia and negligible hypertension were observed.

To investigate the possible role of previous medical history and previous medications as risk factors for hairy cell leukaemia (HCL) we performed a population based case-control study on 121 male HCL patients and 484 controls. The data were collected through a self-administered mailed questionnaire. Elevated odds ratios (OR) were found for a history of appendicitis [OR 1.9; 95% confidence interval (CI) 0.9-4.2] and pneumonia (OR 2.9; CI 0.9-9.6). We found a reduced risk for HCL associated with a history of myocardial infarction (OR 0.3; CI 0.4-2.5), hypertension (OR 0.6; CI 0.3-1.2) and thromboembolic disease (OR 0.6; CI 0.1-2.7). Reduced OR was also associated to a history of diabetes mellitus (OR 0.6; CI 0.1-2.9) and a diagnosis of hyperlipidemia (OR 0.8; CI 0.2-3.6). HCL is an indolent disease with a clinical course of many years and it can not be excluded that the disease leads to metabolic changes, resulting in a changed risk for these diagnoses. When the role of previous medications were investigated, increased OR was found for NSAID (OR 3.4; CI 1.1-10.2). Decreased OR was found for the anti-coagulative agent warfarin (OR 0.4; CI 0.1-1.5). A history of a previous malignancy preceeding the diagnosis of HCL as reported to the Swedish Cancer Registry yielded an increased OR of 3.2 (CI 1.2-8.5). All results must be interpreted with caution, as there is a possibility of misclassification. Medications is difficults to remember, particularly several years after consumption. As many comparisons were made, there is always a possibility of correlations occuring by chance.
