Post-operative infection is often due to a combination of several factors. A decrease in immune defence processes represents the first factor. This is seen in situations such as malnutrition (undernourishment or obesity), alcoholism, diabetes, neoplasms, infections and old age. It may also be induced by therapy such as immunodepressants, antimitotic chemotherapy, corticosteroids and radiotherapy. Finally, certain antibiotics have been accused of reducing immune defences. The second factor responsible for infection is bacterial flora. Errors such as broad spectrum antibiotic therapy prescribed in the presence of unexplored fever, or changed repeatedly, are responsible for imbalance in the bacterial flora and the acquisition of resistance to antibiotics. These errors firstly increased the prevalence of infections and, secondly their severity and the difficulty of their treatment. The last factor responsible for infection is rupture of the natural barriers formed by the skin and mucosae. This is related on the one hand to surgery itself and, secondly, to the intensive care techniques surrounding the surgical act: venous catheterization above all, but also bladder catheterization, tracheal intubation, etc.

Two samples of muscles, one with proved, the other with doubtful neurogenic lesions have been investigated with EMG frequency analysis. Confirming reports from previous authors it was possible to show that a large proportion of muscles with proved lesions have a displacement of the frequency spectrum towards low frequencies("bass" displacement). The displacements were principally found in cases with old lesions. In a group of cases in which the symptoms had lasted a few months only a displacement towards high frequencies ("descant" displacement) was revealed. In view of these findings it was surprising to note a relatively large number of spectra with bass displacement in a group of cases in which the symptoms had lasted less than one month. The probable explanation of this is to be found in the fact that the muscles with bass displacement in this group principally belonged to patients with systemic diseases such as diabetes, alcoholism, renal insufficiency, itc., who quite possibly might have had earlier neurogenic lesions with a subclinical course. In the group of muscles with doubtful neurogenic lesions there was also found a comparatively large number of bass-displaced spectra. It was possible to show that here also there was a large number of patients with systemic diseases.

A retrospective study of adult congestive cardiomyopathy was carried out; the admission criteria being heart failure with cardiomegaly after the exclusion of known causes of heart failure. Coronary artery disease was excluded by forming two sub groups, one with proven normal coronary arteries at angiography or autopsy and the other with only assumedly normal coronary arteries. The results concern the study of the incidence of this disease which has been regularly seen over the last 10 years in departments with a large number of referrals of cardiomyopathy. --Professional factors are analysed to see if there is a higher incidence amongst the working classes. --Other factors are analysed by comparison with three control groups: normal, coronary and valvular disease, and diabetes which may be a predisposing factor, but not the serum cholesterol which is decreased in these patients. There is a significant association with smoking and alcoholism and the main biological sign of the latter condition, macrocytosis. This is also found in both coronary sub groups. The isolation of this alcohol factor in the genesis of congestive cardiomyopathy implies the possibility of reversing or stabilising the myocardial damage after its withdrawal, so changing the severe diagnosis associated with this disease.

A person's sexual readjustment following a physical disability has traditionally been ignored by health care professionals. Since the occupational therapist often facilitates a person's resumption of activities of daily living, the therapist is in a special position to provide counseling. Understanding, support, and correct information are needed most. As derived from a search of the literature, sexual functioning is discussed in relation to the following disabilities: stroke, heart disease, diabetes mellitus, muscular dystrophy, multiple sclerosis, renal disease, spinal cord injury, pulmonary disease, arthritis, and alcoholism.

The clinical and biochemical features of eleven patients with Type V hyperlipoproteinaemia have been reviewed. All patients were male, and there was a high incidence in the group of obesity, vascular disease, acute abdominal pain, gout, diabetes mellitus and alcoholism. Plasma cholesterol concentrations ranged from 212 to 1512 mg/100ml and triglycerides from 708 to 7670 mg/100 ml. Lipaemia was associated with significant hyponatraemia, and also interfered with the determination of plasma glucose and serum amylase. Chylomicronaemia and hyperprebetalipoproteinaemia were accompanied by reduction in the pools of beta and alpha lipoproteins. All lipoprotein classes were relatively depleted of cholesterol compared to triglyceride. There was a variable pattern of treatment response. In some patients alcohol withdrawal produced a rapid improvement in plasma lipids. In diabetes mellitus there were two types of response: a rapid one in chronic insulin deficiency, and secondly, a more gradual one in mild diabetes associated with hyperinsulinaemia. In other patients there was a rapid response to carbohydrate-calorie restriction but the respective contributions of each of the steps remained unclear.

Recovery of herpes simplex virus (HSV) Type 1 from the blood buffy coat of four adults is reported for the first time. All of the patients had vesicular stomatitis and facial vesicles; two also had either keratoconjunctivitis or disseminated skin lesions. The infection was not the primary one with HSV in any of them. Two of three patients who had renal failure were receiving immunosuppressive drugs; one patient was normal except for alcoholism and diabetes. None developed signs of visceral organ infection and all recovered within 2 to 4 weeks. The findings demonstrate the occurrence of heretofore unrecognized nonfatal HSV Type 1 viremia in both healthy and immunosuppressed leukocytes, can occur regardless of the presence of serum antibody, and may or may not be associated with the disseminated lesions.

Type V hyperlipemia is not very common. The series of 54 cases descrubed here is the largest reported to date. Our observations were recorded when lipidograms showed the presence of chylomicrons and a large pre-beta-lipoprotein spot in the serum of fasting subjects. Type V hyperlipemia was often combined with other metabolic syndromes such as diabetes, hyperuricemia or gout, or obesity. Chronic alcoholism was also noted in half our subjects, in whom hyperlipemia quickly regressed after alcohol consumption ceased. Ischemic arterial complications, chiefly coronary, were found in one third of our cases, and the vascular risks accompanying this type of hyperlipemia rose considerably in patients with high blood pressure. Various type of treatment were administered, but all subjects were put on a special diet, comprising either the elimination of alcoholic drinks only, or, in addition to this, reduced carbohydrate or calorie intake. As a rule, these measures resulted in a distinct regression of lipid anomalies. Clofibrate or derivatives proved effective in cases where hyperlipemia failed to respond to dietary measures.

The enzyme gamma-glutamyl transpeptidase is widely distributed throughout the body, notably kidney, seminal vesicles, pancreas, liver, spleen and brain. Being one of the enzymes of the gamma-glutamyl cycle, it is involved in aminoacid transport, catalysing a transpeptidation reaction between gamma-glutamyl peptides and most common amino acids. Methods of assay of the enzyme are based on its ability also to act on synthetic amides of glutamic acid; kinetic methods monitoring the release of p-nitroaniline from the substrate L-gamma-glutamyl p-nitroanilide are the most satisfactory. In diseases of the liver, the highest levels occur in association with cirrhosis, alcoholism, hepatic secondaries and cholestasis. As the enzyme is present in the endoplasmic reticulum of the hepatocyte, its activity is increased in situations leading to microsomal enzyme induction. Raised levels can also occur in pancreatitis, diabetes, myocardial infarction, congestive cardiac failure, chronic renal failure, cerebrovascular accidents, cerebral tumours and chronic obstructive pulmonary disease. Although the lack of specificity must be recognised, the estimation can be useful in the elucidation of some clearly defined problems arising during investigation of patients with suspected hepatic disease, especially where performed as part of a biochemical profile.

In a survey report pathological aspects and clinical importance of the secondary forms of hyperlipoproteinaemia are dealt with. At first are taken into consideration the relations between hyperlipoproteinaemia and diabetes mellitus. Furthermore is referred to the secondary hyperlipoproteinaemias in kidney diseases, pancreatitis, alcoholism, thesaurismoses, endocrine diseases and liver diseases as well as under different medicaments. Finally the therapeutic problems of the secondary hyperlipoproteinaemias are concerned.

Based on the results of quantitative isotope ventriculography (QIV) a group of 25 patients was divided into 17 hydrocephalic and 8 non- or doubtfully hydrocephalic patients. An atrio-ventricular shunt (A-V shunt) was inserted in all 25 patients. Eight of the hydrocephalic patients improved or became well, while nine hydrocephalic patients were unchanged, worse or dead at the time of follow-up. These nine patients suffered either from severe brain damage, chronic alcoholism over several years, arterial hypertension, severe diabetes, or acute meningo-encephalitis caused by a virus infection. None of the eight non- or doubtfully hydrocephalic patients improved after the operation. From this it was concluded that QIV is of considerable diagnostic value in acquired hydrocephalus.
