We measured acetate concentrations in whole blood, serum, and plasma by a modification of a previously described method involving vacuum distillation and gas chromatography. The mean acetate concentration of fresh venous plasma from 27 normal subjects was 51 +/- 5 mumol/L (95% confidence limits ranged from 0 to 103 mumol/L). The acetate concentrations of serum and plasma incubated for 2 h at either 4 degrees C or 27 degrees C were the same. The acetate concentration of whole blood incubated at 27 degrees C was significantly greater than that of blood incubated at 4 degrees C. This change may have resulted from the production of acetate by erythrocytes or from the hydrolysis of acetate esters. Storage of plasma at -20 degrees C for 24 h significantly increased acetate concentrations from 26 +/- 6 mumol/L to 63 +/- 4 mumol/L. After the subjects consumed a standard breakfast, venous plasma acetate concentrations increased from 58 to 97 mumol/L at 30 min. Acetate concentrations in arterial plasma exceeded those in venous plasma. Plasma acetate concentrations were not significantly altered in patients with malignancy or diabetes mellitus, but severe liver disease and severe acidosis were both associated with increased acetate concentrations. These preliminary observations suggest that plasma acetate concentrations may be altered in several disease states.

The suggested association between high consumption of beer and an increased risk of death from cancer of the colon and rectum was investigated among blue-collar workers at a Dublin brewery, who consume more than average amounts of beer, usually in the form of stout. A study of their mortality between 1954 and 1973 showed that they had as good an expectation of life as all Dublin males, with no increased risk of death from cancer of the oesophagus, pharynx, liver or of cirrhosis of the liver, accidents or suicide, conditions normally associated with the high consumption of alcohol. They had significantly increased risk of death from cancer of the rectum and also from diabetes mellitus. Twenty per cent of the workers, differentiated by their place of work within the brewery, had a much higher risk of death from cancer of the rectum.

Microcysts of the iris pigment epithelium have been described in association with diabetes mellitus, systemic mucopolysaccharidoses. Menkes's syndrome, and in neonates. Our study covers 68 cases obtained at necropsy. We specifically examined the iris pigment epithelium for vacuolation. We found that microcysts are more widespread than previously thought. In our series 57.3% of the cases reviewed by the light microscope showed microcysts. Of interest was the relationship of malignant neoplasm to iris pigment epithelium microcyst: 69.4% of cases with malignancy showed microcyst, whereas only 30% of the cases without neoplasms showed microcysts. Patients treated with exogenous steroid also had a raised incidence of microcysts.

The authors discuss the main features of the complex pathophysiology of patients subjected to duodenocephalopancreatectomy, and particularly the difficulties inherent in clinical assessment of the digestive and metabolic impairment consequent upon the duodeno-gastro-pancreatic mutilation. Out of a total of 57 cases of this description, they singled out for recheck 23 patients who had undergone duodenocephalopancreatectomy not less than six months and not more than seven years before (chronic pancreatitis, 11 cases; various malignancies of the periampullar area, 10 cases; Zollinger-Ellison syndrome, 1 case; retroperitoneal lymphoma, 1 case). Seventy-six per cent of patients who had been gainfully employed were able to resume their jobs after surgery. Steatorrhea, assessed in terms of fecal fats, was present in all cases; notwithstanding, 70% of the patients gained weight (average increase 7 kg). All patients were on enzyme replacement therapy. Only 4% developed diabetes, and none developed postoperative peptic ulcers. Conversely there was a high incidence (65%) of bone structure reshuffling, signally osteoporosis, probably imputable to steatorrhea and vitamin D malabsorption, plus the often associated increase of serum alkaline phosphatase activity.

The jet-wash technique is an efficient method for diagnosing the endometrium carcinoma. Among 750 women we detected 50 endometrium carcinomata all of which were diagnosed by the jet-wash method. Wrongly positive findings do not exist in our series of examinations. Of the pre-stages of the endometrium carcinoma, such as adenomatous hyperplasia and adenocarcinoma in situ, however, only scarcely 50 per cent of all cases were diagnosed. The jet-wash method is also suited for outpatient clinics. Thus, patients with risk-factors for the endometrium carcinoma might be controlled annually once in outpatient clinics in addition to the usual cancer prophylactic examinations. Above all, we consider 1. patients suffering from bleeding anomalies as from the 40th year of age, 2. patients free from any symptoms, but suffering from obesity, hypertension and diabetes mellitus, 3. patients with an increased narcosis risk, 4. patients of the perimeno-pause prior to an estrogen treatment and 5. cancer post-care patients suffering from a primarily radiated endometrium carcinoma. The direct smears and the cytocentrifuge preparations can be diagnosed right on the day of examination. The thrombin cell block technique requires more work for a cytological laboratory. For a histological laboratory it might not mean any additional essential burden.

Sixty-five patients operated with total pancreatectomy were reviewed with respect to factors influencing operative mortality and morbidity, long-term survival, and metabolic sequelae. The diagnoses were pancreatic cancer in 58 patients, periampullary cancer in three, cancer of the bile duct in two and leiomyosarcoma of the duodenum and cystadenocarcinoma of the pancreas in one patient, respectively. In nine of the 58 cases with cancer of the caput, the histological examination revealed multicentricity of the tumor. In 44%, there were signs of degeneration and fibrosis in the distal part of the gland. Hospital mortality was 23% for the entire series. After 1970 the hospital mortality was 17%, and among patients operated by senior surgeons especially trained in pancreatic surgery, the hospital mortality was 12% during the whole period. The peroperative bilirubin levels seemed to influence survival time. Among 24 patients operated before 1975 in whom the operating surgeon judged the operation as radical, a five year survival of 21% was recorded. In patients without detectable lymph node metastases, the mean survival time was 25 months. The postoperative exocrine insufficiency and diabetes were possible to control. A blood sugar level above 10 micromol/l was found to significantly decrease the frequency of hypoglycemic attacks. Total pancreatectomy appears to be the surgical procedure preferred when radical treatment is selected.

Coffee as a rule develops stimulating effects on the central nervous system, heart and circulation which are mainly caused by caffeine. In certain cases coffee may also have a sedative effect and sometimes even it is useful to fall asleep quickly. Furthermore coffee may be advantageous in the treatment of some functional disorders caused by lacking of dopamine, because coffee is able to increase the dopamine formation in brain. Concerning the effects of coffee in the gastrointestinal-tract and liver-bile system caffeine is only of secondary importance. Hereby certain roasting substances, possibly also chlorogenic acid or caffeic acid should be responsible for the stimulating effects observed in these organs. These stimulating effects could be caused whether directly or indirect e.g. by liberating gastrin or other gastrointestinal hormones. Vitamin niacin, which is formed in greater amounts from trigonelline during the roasting process, may also be important from the nutritional standpoint. Therefore coffee may be prescribed as a true drug in cases of deficiency in vitamin niacin or also in the pellagra disease. By extensive epidemiological studies performed lately it could be demonstrated that there exists no correlation between coffee consumption and certain risk factors as hypertension, heart infarction, diabetes, gout or cancer diseases. Furthermore there was no evidence that coffee or its caffeine content are able to induce genetic alterations or even malformations.

Fibrinolytic therapy was started 90 min after central retinal occlusion in a 62-year-old male patient, but the retinal function did not recover. Another patient, aged 64 years, with occlusion of a retinal artery branch, had therapy started only 6 hours after the event and showed full recovery as was documented by angiography. General contraindications against fibrinolytic therapy are: hypertension over 200 mm Hg, arteriosclerosis, diabetes with retinal changes, previous cerebral insults, malignancy or ulcer, hepatocirrhosis, recent surgical or angiographic interventions, renal insufficiency, pregnancy, cogenital or acquired abnormal blood coagulation. If these contraindications do not apply, fibrinolytic therapy of central retinal arterial obstruction is recommended provided this therapy can be started not later than 6 hours after the event. Occlusions of the central retinal vein should have fibrinolytic therapy only if there are very few haemorrhages and if the occlusion is not older than 24 hours.

Although the nature of firefighting involves particular health hazards, previous mortality and morbidity studies of firemen have produced inconsistent evidence for an increased risk of mortality from cardiovascular disease, respiratory disease, cancer and accidents. Mortality experience since 1915 has been examined in 5655 Boston firefighters, comprising all male members of the city fire department with three or more years of service. The observed cause of death as stated on the death certificates of 2470 deceased firefighters has been compared with the numbers expected based on rates for the male population of Massachusetts and of the United States of America. Among all firefighters, deaths from all causes were 91% of expected. The standardised mortality ratio (SMR) was markedly reduced (less than 50) for infectious disease, diabetes, rheumatic heart disease, chronic nephritis, blood diseases and suicide. The SMR was 86 for cardiovascular deaths, 83 for neoplastic deaths, and 93 for respiratory deaths. The SMR for accidents was 135 for active firefighters. The results suggest that the survival experience of firefighters is strongly influenced by strict entry selection procedures, ethnic derivation, and sociocultural attributes of membership. While excessive morbidity has been demonstrated in firefighters, there does not appear to be a strong association between occupation and cause-specific mortality.

41.5% of 200 newborn infants had levels of carcinoembryonic antigen (CEA) in excess of 2.5 ng/ml in their cord plasma. There was no direct correlation with the maternal CEA level although the frequency of elevated CEA was significantly greater among infants born to mothers with CEA levels greater than 2.5 ng/ml. There was no preponderance of high CEA levels among infants with low birth weights and there was no influence of maternal smoking on a cord CEA level. There was a tendency toward an increased incidence of cancer in families with infants who had elevated CEA levels and a reverse trend was noted with respect to diabetes; however, these associations were not statistically significant. We were unable to define clearly the factors accounting for the persistent elevation of this oncofetal antigen at birth; however, the possible association with susceptibility to the development of neoplasia merits further study.
