In summary, the vitamin pantothenic acid is an integral part of the acylation carriers, CoA and acyl carrier protein (ACP). The vitamin is readily available from diverse dietary sources, a fact which is underscored by the difficulty encountered in attempting to induce pantothenate deficiency. Although pantothenic acid deficiency has not been linked with any particular disease, deficiency of the vitamin results in generalized malaise clinically. In view of the fact that pantothenate is required for the synthesis of CoA, it is surprising that tissue CoA levels are not altered in pantothenate deficiency. This suggests that the cell is equipped to conserve its pantothenate content, possibly by a recycling mechanism for utilizing pantothenate obtained from degradation of pantothenate-containing molecules. Although the steps involved in the conversion of pantothenate to CoA have been characterized, much remains to be done to understand the regulation of CoA synthesis. In particular, in view of what is known about the in vitro regulation of pantothenate kinase, it is surprising that the enzyme is active in vivo, since factors that are known to inhibit the enzyme are present in excess of the concentrations known to inhibit the enzyme. Thus, other physiological regulatory factors (which are largely unknown) must counteract the effects of these inhibitors, since the pantothenate-to-CoA conversion is operative in vivo. Another step in the biosynthetic pathway that may be rate limiting is the conversion of 4'-phosphopantetheine (4'-PP) to dephospho-CoA, a step catalyzed by 4'-phosphopantetheine adenylyl-transferase. In mammalian systems, this step may occur in the mitochondria or in the cytosol. The teleological significance of these two pathways remains to be established, particularly since mitochondria are capable of transporting CoA from the cytosol. Altered homeostasis of CoA has been observed in diverse disease states including starvation, diabetes, alcoholism, Reye syndrome (RS), medium-chain acyl CoA dehydrogenase deficiency, vitamin B12 deficiency, and certain tumors. Hormones, such as glucocorticoids, insulin, and glucagon, as well as drugs, such as clofibrate, also affect tissue CoA levels. It is not known whether the abnormal metabolism observed in these conditions is the result of altered CoA metabolism or whether CoA levels change in response to hormonal or nonhormonal perturbations brought about in these conditions. In other words, a cause-effect relation remains to be elucidated. It is also not known whether the altered CoA metabolism (be it cause or result of abnormal metabolism) can be implicated in the manifestations of a disease. Besides CoA, pantothenic acid is also an integral part of the ACP molecule.(ABSTRACT TRUNCATED AT 400 WORDS)

Between December 15, 1988 and November 30, 1990, the application of Rome and New York criteria enabled the diagnosis of 60 cases of gout among patients with arthritis or hyperuricemia seen as out-patients or hospitalised in the Department of Rheumatology of the Brazzavile T.H.G. There were 57 men and 3 women, with a mean age of 51. Gout is the primary form of inflammatory arthropathy in adults in the Congo. Affecting all socio-professional groups, it is diversely associated with obesity, alcoholism, hypertension and diabetes. Initial involvement affects the big toe. Oligo and polyarticular forms predominate because of the absence or delay in specific treatment. This series included 30 per cent of cases of chronic gout. Evidence of renal impairment was found in one third of patients. However, urate lithiasis was absent. Tophi were found preferentially over the elbows. Sickle cell disease was responsible for one case of tophaceous gout. In contrast with the results of studies undertaken before the 1980s, gout is seen to be a common condition in equatorial Africa.

A retrospective study of 194 patients is carried out. Patients were divided into two groups: 154 patients with acute cerebrovascular accident (ACA) and 40 patients without vascular pathology, hospitalized for other causes. A descriptive analysis of these patients is made with respect to age, sex, type of ACA, previous ACA and potential relationship between the type of this first ACA and the one motivating current hospitalization. In addition, ACA is related to risk factors (hypertension, dyslipemia, diabetes, cardiopathy). In our series, variables that can be considered as risk factors, with significant differences between both groups, are: HTA, tobacco consumption, cardiopathy, dyslipemia (hypercholesterolemia and hypertriglycemia, hyperuricemia and diabetes. Alcoholism, anticoagulation, antiaggregation or polyglobulia were not risk factors. In 33.2% of patients with current ACAs, there were antecedent of clinically documented cerebrovascular pathology; one thing of them were transitory cerebral ischemias and more than half of them, cerebral infarcts. In conclusion, we stressed the role of primary and secondary prevention acting against risk factors, given the recurrence of this pathology and the irreversibility of the injuries once happened.

Oesophageal intramural pseudodiverticulosis is characterized by a segmental or diffuse distribution of numerous small outpouchings varying in size from 1 to 5 mm. Review of previously described cases revealed a significant incidence of associated debilitating systemic disorders such as diabetes mellitus, malignancy, alcoholism and tuberculosis. No record could be found in the literature of a similar process occurring in other parts of the gastro-intestinal tract. A case is reported of a severe alcoholic who, on a barium swallow, in addition to the changes of oesophageal intramural pseudodiverticulosis, presented with a large duodenal ulcer and similar outpouchings in the first and second parts of the duodenum.

Life expectancy and physical fitness of patients with neurogenic bladder dysfunctions is highly dependent on the urine status of the patient, and on the integrity and function of the upper urinary tract. Residual urine and urine incontinence give rise to infections, a vicious circle which ends with uraemia. Following nerve disorders can be the cause of a bladder dysfunction with outflow obstruction thus bearing the risk of ascending urine infection: 1) complete or incomplete spinal cord lesion, 2) myelomeningocele, 3) diseases of the CNS, 4) peripheral neuropathy (diabetes, chronic alcoholism, infectious diseases), 5) effect or side-effect of medications. An infravesical obstruction can occur at the alpha-adrenergic receptor site, at the level of the bladder neck or at the level of the striated external sphincter. The latter condition was termed detrusor-sphincter-dyssynergia. Instrumental bladder emptying for prevention of UTI can be achieved by: 1) catheterisation, 2) intermittent self catheterisation, 3) indwelling catheter--should be avoided for long term drainage, 4) suprapubic bladder drainage (cystocath)--the best treatment option for emptying the bladder and to avoid infections.

The objective causes of sexual impotency include chronic prostatitis arising from bacterial infection (1/3 of patients have sexual disturbances), congestive prostatitis (owing to sexual hyperstimulation treated with temporary blockage of testosterone), and hemorrhoids. Diabetes, advances tuberculosis, neurological and psychological diseases also negatively impact sexual potency as does alcoholism. The increase of dopamine and the decrease of serotonin stimulate, while the reverse of these reduce sexual activity. Endocrine medicines, drugs that affect the central nervous system, antihypertension drugs, anticoagulants, vincristine, cimetidine, and clofibrate generally lower the libido. Methods to be avoided because of a negative effect on sexual life include coitus interruptus. The intolerance of sensitivity to the sperm of the partner also complicates the sexual life of a couple. Sexual disorders without apparent cause include the lack of harmony, attention, and education about sexual matters. Other disorders can be caused by rape (only 25% of rapists are caught and punished), as 50% of female victims have psychological sequelae with a sexual tone; venereophobia; repulsive cutaneous symptoms; emotional taste; fear of inability to complete the sexual act; timidity or excessive shyness with anxiety about intimacy; and lack of emotional attraction to the partner. Eventually, the lack of a satisfactory sexual life has an effect on the integrity of conjugal life, as it is frequently the cause of divorce.

A personal series of 6780 patients with diabetes mellitus is reported. Of these 1410 were thought to have insulin-dependent (Type 1) diabetes and 4926 non-insulin-dependent (Type 2) diabetes. Among the former, 128 patients were only diagnosed when in severe ketoacidosis or coma. In 116 patients the diabetes was diagnosed in pregnancy. Chronic alcoholism was an aetiological factor in 75 patients; in 52 it led to the diagnosis being made, and it complicated treatment in 129 additional patients. In the patients with Type 2 diabetes whose treatment was stabilized 23.5% were having insulin injections, 44.5% tablets, and 32.0% diet only. Sight-threatening retinopathy developed in 21.3% of patients with Type 1 and 7.9% of those with Type 2 diabetes. The rate of developing sight-threatening retinopathy was 1.1% of patients per year. Blindness occurred in 0.28% of patients with Type 1 diabetes per year and 0.097% per year in Type 2 diabetes. If the mean survival of patients with retinopathy going blind is 7.5 years, this would mean 7500 people in the UK blind from diabetic retinopathy. There was a striking drop in the annual incidence of blindness after 1970 coinciding with the introduction of specific treatment for diabetic retinopathy. Juvenile cataract developed in 1.7% of patients who developed Type 1 diabetes before 30 years of age. Clinically important diabetic neuropathy developed in 17.4% of patients with Type 1 and 11.6% of those with Type 2 diabetes. The main features were paraesthesiae and numbness (49%), neuropathic ulceration (37%), pain (5%), autonomic symptoms (5%), and amyotrophy (4%). Oculomotor palsies and mononeuropathies were noted. Foot ulceration occurred in 81 patients with Type 1 and 279 of those with Type 2 diabetes. Charcot changes in the feet were noted in 21 patients. Major amputations were needed in 18 patients with Type 1 and 60 with Type 2 diabetes. Proteinuria believed to be due to diabetic nephropathy developed in 12.8% of patients with Type 1 and 4.7% of those with Type 2 diabetes. The prevalence of early renal failure was 4.6% and 1.4%, respectively. Coronary artery disease was noted in 9% of patients with Type 1 diabetes, and was more common in those who developed diabetes after 20 years of age. Myocardial infarction was as common in women as in men. In Type 2 diabetes coronary artery disease gave rise to symptoms in 19.1%, and myocardial infarction was more common in men.(ABSTRACT TRUNCATED AT 400 WORDS)

Tuberculosis is coexistent with pneumoconioses, alcoholism, ulcer disease, renal failure, malignancies and immunosuppression. The aim of the study was to determine the incidence rates of tuberculosis and therapeutical efficacy in patients with coexistent alcoholism, ulcer disease, diabetes and mental disturbances. In Wroclaw in the years 1982-1986 1,454 patients were recorded with fresh tuberculosis; 164 (11%) were alcoholics, 52 (3%) had ulcer disease, 32 (2%)-diabetes mellitus and 16 (1%) with mental disturbances. The remaining 1,105 patients made up the control. The diagnosis of tuberculosis in patients with mental disturbances and alcoholics is usually made during a medical check-up, while in patients with the other diseases basing on clinical findings. Recurrences were found only in patients with coexistent diabetes mellitus and tuberculosis. The results of treatment did not differ from that of the control. Sputum conversion was found in 96%, 3% died and 1% was moved to the group of patients with chronic disease.

A total of 1,030 diabetic patients were studied in order to identify factors associated with various complications. A higher proportion of women was found (64.1%). Using regression analysis of prevalence versus the logarithm of the duration of diabetes, a half-life of 5.14 years was calculated. In the study of complications, peripheral neuropathy, amputations, renal impairment, albuminuria, myocardial infarction, cataract and amaurosis were strongly associated with duration of diabetes rather than with the age of the patient or the age at diagnosis; in contrast, blood pressure and impotence correlated better with the age of the patient. A discriminant function analysis permitted to identify several factors as predictors of diverse complication mainly: the duration of the disease, and previous use of insulin (negative correlation). Other predictors were glycemia, alcoholism, smoking habit and intake of legumes (beans). Albuminuria was assessed with a radioimmunoassay procedure and found to be associated with: duration of diabetes, urinary tract infection, systolic blood pressure and amaurosis. Some alimentary habits were also included as predictors of complications.

American former prisoners of war (POWs) are an aging group who seek health care with increasing frequency. To examine the prevalence of long-term physical and emotional consequences of captivity in this population, the authors analyzed medical and psychiatric examination data for 426 former POWs. Detailed psychiatric diagnostic criteria were used to assess the POWs' mental health. Compared with general population groups, POWs had moderately elevated lifetime prevalence rates of depressive disorders and greatly elevated rates of posttraumatic stress disorder (PTSD), although their rates of hypertension, diabetes, myocardial infarction, bipolar disorder, schizophrenia, and alcoholism were not elevated. POWs who lost more than 35 percent of their body weight during captivity had higher rates of anxiety disorder, depressive disorders, PTSD, and schizophrenia, compared with other POWs.
