The frequency of hypertension in a group of alcoholics and the incidence of alcohol abuse in a group of patients with hypertension was compared with a collective with type-II-diabetes. There is a high relationship between alcoholics and hypertension, a lower one between alcohol abuse in the hypertension group. Chronic alcohol abuse seems to be a more important risk factor for the development of hypertension than diabetes. Genesis and therapeutic consequences of alcohol-induced hypertension are discussed.

Recent longitudinal studies have improved the knowledge of the natural history of chronic pancreatitis. This disease is mainly induced by alcohol abuse. Mean age at onset of the disease is 40 years. First symptoms are generally pain, often related to acute pancreatitis. Over the first five years of course, complications as pseudocysts or common bile duct stenoses can occur, often necessitating surgical treatment. In the late course, the disease becomes less symptomatic but the risk of diabetes mellitus increases. Occurrence of pancreatic calcifications is observed with time in the majority of patients. Chronic pancreatitis is associated with overmortality but the causes of death are mainly extrapancreatic (alcoholic liver disease and cancers). Abnormalities of pancreatic secretion induced by alcohol abuse play an important role in the pathophysiology of the disease: it is possible that the decrease of concentration of the "pancreatic stone protein" promotes formation of calcifications. Direct toxicity of alcohol is another possible factor.

This study was performed to ascertain the role of serum markers and simple clinical data in detecting pancreatic cancer and in distinguishing this malignancy from chronic pancreatitis and other gastrointestinal diseases. Serum CA 19-9, tissue polypeptide antigen and carcinoembryonic antigen were measured in 38 control subjects, 37 patients with pancreatic cancer, 39 with chronic pancreatitis and 44 with extra-pancreatic diseases mainly of gastrointestinal origin. Clinical data recorded included age, sex, presence of pancreatic calcifications, weight loss, pain, jaundice, alcohol abuse, diabetes mellitus. Serum markers gave a correct allocation of the subjects in 48.1% of the cases with pancreatic cancer patients correctly predicted in 62.2%. Clinical data correctly diagnosed 74.2% of subjects. Chronic pancreatitis was identified in 84.6% of the cases and pancreatic cancer in 64.9%. The first clinical variables selected were pain and age. The addition of serum markers to clinical data did not enhance accuracy of the results. We conclude that the diagnosis of chronic pancreatic diseases should first be suspected on the basis of accurately recorded simple clinical data; serum markers seem to be only occasionally useful. Since indicative clinical data and serum markers become positive in the advanced phases of pancreatic cancer, early diagnosis of this malignancy still remains an objective to reach.

The relationship between monoclonal gammapathies and peripheral nerve involvement is well known. The pathogenesis of neuropathy has been ascribed to infiltrative, compressive, ischemic or haemorrhagic phenomena, to an amyloid storage or to antibody autoaggression toward neural antigens. Forty-five patients suffering from monoclonal gammapathy of uncertain significance (MGUS), multiple myeloma (MM), MG IgM, were submitted to a neurophysiological examination. 10 pts. were excluded because of neurotoxic drugs, diabetes or alcohol abuse. The investigation included SCV of median, ulnar, and sural n., MCV and F wave of peroneal n., H reflex, and computerized analysis of recruitment pattern. A subclinical neuropathy was found in 11 of 35 pts. (30%) without any neurological symptom. A CTS was found in 4 patients. The high rate of subclinical neuropathy in asymptomatic pts. is underlined by the Authors, while the presence of subclinical neuropathy in cases of MGUS needs further studies.

In 1987-1988 160 type 2 diabetics, dispensarized in diabetological out-patient departments of the medical clinic of the Institute for Postgraduate training were subjected to neurological examinations. The selection of the group was governed by an effort to reduce to a minimum the association of other neurotoxic influences. The group therefore comprised subjects under 60 years of age; diabetics with other diseases with a possible neurotoxic action, drug abuse, alcohol abuse, etc. were eliminated. After a detailed neurological examination signs of affection of the peripheral nervous system were detected in 87.5%, clinically manifest diabetic neuropathy was found in 78 diabetics (48.75%); 12 had moreover mononeuropathy of the median nerve. The clinical picture was uniform: impaired perception of vibrations on the acra of the lower extremities with ascendent propagation, reduction to disappearance tendinous-muscular reflexes on the lower extremities. Subjectively more frequently cramps of the feet than paraesthesias were reported. The authors revealed that long-term compensation of diabetes, the duration of diabetes and the biological age of the diabetics were statistically significant for the manifestation of diabetic neuropathy. This significance was proved for the factor of biological age (p less than 0.05); there was also a significant correlation between the long-term state of compensation of type 2 diabetes and the manifestation of neuropathy (p = 0.06).

Diabetes mellitus caused by pancreatic exocrine disease is a unique clinical and metabolic form of diabetes. The diagnosis of pancreatic diabetes caused by chronic pancreatitis may be elusive because it is occasionally painless and often not accompanied by clinical malabsorption until after hyperglycemia occurs. Diabetic patients with pancreatic calcification or clinically demonstrable pancreatic exocrine dysfunction will manifest the unique aspects of pancreatic diabetes described herein. Like other forms of diabetes, the primary hormonal abnormality in pancreatic diabetes is decreased insulin secretion. Patients with this disorder are unique in that they have low glucagon levels that respond abnormally to several physiological stimuli, blunted epinephrine responses to insulin-induced hypoglycemia, and malabsorption. In addition, they often have concomitant alcohol abuse with hepatic disease and poor nutrition. These characteristics result in increased levels of circulating gluconeogenic amino acids, decreased insulin requirements, a resistance to ketosis, low cholesterol levels, an increased risk of hypoglycemia while on insulin therapy, and the clinical impression of brittle diabetes. Retinopathy occurs at a rate equal to that of insulin-dependent diabetes but may be less severe in degree. Other complications of pancreatic diabetes have been less well studied but may be expected to be seen more frequently as these patients survive longer. The characteristics of pancreatic diabetes suggest that a conservative approach be taken in regard to intensive insulin therapy and tight blood glucose control.

It is common for patients to be diagnosed as having valvular regurgitation by Doppler echo when no such murmur has been heard by the referring clinician. To test the hypothesis that such patients have clinically unimportant heart disease, the authors evaluated the records of 213 consecutive men in whom mitral regurgitation had been found by pulsed Doppler. In 95 patients (group I) mitral regurgitation was audible, whereas in the other 118, it was not. In 97 patients with inaudible mitral regurgitation there were no structural mitral valve abnormalities by 2D echo. This group of 97 patients (group II) was defined as having unexpected Doppler mitral regurgitation. In group II patients there was a high prevalence of hypertension (50%), congestive heart failure (44%), alcohol abuse (46%), diabetes (27%), coronary artery disease (63%), and atrial fibrillation (13%). The following variables were distributed similarly in groups I and II: survival time, age, presence of congestive heart failure or coronary artery disease, left ventricular short-axis end diastolic and end systolic dimensions, E point septal separation, and the severity of dyssynergy. Atrial fibrillation was more common in group I (p = 0.017), and group I patients had a higher Quetelet's Index (weight/height squared) (p = 0.03). In group II, the factors most closely related to survival were the presence of dyssynergy, of atrial fibrillation, or of congestive heart failure. Although no group II patient had endocarditis or required mitral valve replacement, their survival was markedly decreased compared with people of similar age in the general population. The majority of cardiogenic deaths in group II patients were due to coronary artery disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Two patients, aged 51 and 70 years, had indolent ulcerations at the sole of the foot with destructive osteolysis in the bones of the feet, lesions characteristic of mutilating ulcerative acro-osteopathy. Patient 1, who had pes cavus, developed ulcerations on the balls of the feet along the second metatarsal bones, and patient 2 with pes equinovarus developed ulcers in the area of the calcaneus. Sock-like hypesthesia/hypalgesia from the toes to the ankles was present in both patients, and electrophysiological tests confirmed the presence of axonal sensory-motor neuropathy. Diabetes mellitus and alcohol abuse was excluded in both patient. Clinical findings, history and neurological disturbances in both patients identified the disease as hereditary sensory neuropathy (type I).

Six patients with severe ocular side effects caused by therapeutical doses of the tuberculostatic drug ethambutol were investigated during the course of recovery with psychophysical and electrophysiological methods. Three patients developed an optic atrophy with permanently reduced vision as a likely consequence of additional risk factors such as diabetes, alcohol abuse, and reduced kidney function. The severity of the neuritis of the optic nerve was not related to the total intake of ethambutol. The likelihood of a permanent ocular damage increased sharply if the visual acuity had dropped below a value of 1/10. permanently prolonged latency of the P-100 component was found in visual evoked potentials even in cases with good recovery from ethambutol-induced damage. The recovery of color vision could be monitored very well with the Farnsworth-Munsell 100-Hue Test which revealed a diffuse impairment of color discrimination with a slight prevalence of the red-green axis. In addition to the known disturbances of the red-green antagonistic neurons, it could be demonstrated by measuring transient tritanopia and spectral sensitivity functions that ethambutol also affects the blue-yellow antagonism at the retinal level.

This second part of a study comparing general practice consultations in Bourke in 1968 and 1985 examines attendances with non communicable diseases. Over the period, Aboriginal consultations for genitourinary diseases, diabetes, alcohol abuse, hypertension, and musculoskeletal disorders have increased. By 1985, most of these were more common among Aboriginal than non Aboriginal patients in the 30 to 50 year age group. This group also has a higher mortality. The role of the general practitioner is discussed.
