1. Clinical and necropsy observations in lepromatous leprosy associated with severe emaciation and accompanying hypoproteinemia suggest that protein deprivation may be of pathogenic significance in the ulcerative phenomenon that is designated "Lazarine leprosy". 2. An experimental utilizing Wiersung rats infected with Mycobacterium lepraemurium and maintained on a protein-free diet was developed for the purpose of studying the effect of protein starvation on the course of chronic mycobacterial disease similar to lepromatous leprosy with respect to pathogen and host inflammatory response. 3. It was possible to maintain the experimental animals on a protein-free diet for up to 18 weeks of concomitant M. lepraemurium infection. This was long enough for the infection to disseminate to a degree that was evident in control animals only several weeks later. 4. The protein-deprived animals showed decreased inflammatory response to the pathogen, presented more rapid dissemination of the infection and harbored more bacilli per macrophage than did animals similarly infected but maintained on a protein adequate diet. This indicates impairment of native cellular immunity by protein deprivation through decrease in ability of macrophages to inhibit bacillary multiplication. 5. There was no evidence of impairment of macrophage ability to phagocytose the pathogens. 6. Morphologically the increased dissemination of pathogens and decrease in inflammatory response was similar to the increase in number and extent of visceral lesions seen in Lazarine leprosy. Decreased ability to dispose of the infecting bacilli was similar in the two models, human and animal. The animal model does not, as does lepromatous leprosy, involve the skin in the infection. Hence comparable ulcerative phenomena were not replicated in the animals. 7. It is suggested that Lazarine leprosy may result from enhanced lepromatous leprous infection occurring as a result of protein malnutrition. The pathogenic mechanism appears to be impairment of cellular immunity probably enhanced by concomitant impairment of humoral antibody immunity resulting also in decreased resistance to pyogenic and other secondary pathogens. The tissue edema attendant on decreased serum osmotic pressure due to lowering of the serum protein fractions enhances the probability of ulceration.

Although the figure of unreported cases of neglected children is much higher than that of physical ill-treatment of children, neglect has rarely received attention, in most cases only when traces of physical ill-treatment were proven at the same time. Symptomatic are in the first place intense emaciation as well as dry puckered, scaly and extremely dirty skin, lack of subcutaneous fatty tissue and of Bichat's fat pad, matted hair, aged face, sunken eyes, and eczema from urine with ulcerations in the buttock and thigh regions. In addition one finds signs of localized hypothermia or rickets. My own observations cover 54 cases in which neglect and malnutrition have caused the death of the children involved. All the children had been living in extremely bad social conditions. The backgrounds of the children's mothers were also socially poor. Most of the mothers were too young to fulfill their duties. The fathers, where known, were alcoholics, unwilling to work and seldom cared for their family. They too were often too young to cope with their role as father. In this day and age, which has provided us with a much better understanding of the importance of the early development of the child for its later social attitude, mothers with all their problems and difficulties should not be left on their own. Motherlike behaviour is not necessarily programmed with the birth of a child. Mother duties must be learned as early as possible. This process should begin during pregnancy at the latest. A few proposals will be made.

Visual functions and nutrition metabolic characteristics were studied in 8 subjects (16 eyes) with tobacco-toxic optic neuropathy (TTON). Their visual functions tested by psychophysical and electrophysiologic methods showed that 1: 1. central vision diminished in 16 eyes, 2. dyschromatopsias were found in 14 tested eyes, 3. bilateral symmetrical central or cecocentral scotomas were the visual field characteristics in all cases, 4. PVEP were severe abnormal in 3 spatial frequencies in all cases and 56.3% of 15' checkboard PVEP showed flat responses, which indicated the impairment of optic nerve dominated by the central field. However, the preserved visual responses could be obtained by FVEP test in 14 tested eyes even though their visual acuity were between the range of 0.02-0.2 and flat PVEP responses. The II and III wave latencies of primary stage were more prolonged than those of control group (P < 0.01), which further indicated the preferential demyelination corresponding to the papillomacular bundles, 5. ERG showed slightly attenuated amplitudes in 5 of 8 tested eyes, which indicated the secondary and mild retinal lesion. On the other hand, TTON occurred on a background of long-term, heavy smoking, drinking, emaciation and malnutrition bodies with low serum zinc level.

In order to determine the relationship between nutritional, sociodemographic, and obstetrical variables and fetal malnutrition, a study was done on a group of mothers of nonpremature neonates born in a hospital in the central mountainous region of Guatemala. Of the 306 neonates, 105 (34%) presented fetal malnutrition (intrauterine growth retardation, IUGR), which in 77% of the cases was chronic (fetal atrophy, or IUGR type I) and in 23% of the cases was acute (fetal emaciation, or IUGR type II). The maternal factors related to fetal atrophy were puerperal nutritional indicators (weight, height, skinfold thickness, and arm circumference) and sociodemographic indicators (schooling, literacy, and socioeconomic level). Fetal emaciation was found to be related to obstetrical characteristics such as number of previous deliveries and birth interval. The results suggest that poverty, malnutrition, and precarious living conditions over prolonged periods of time are related to chronic fetal malnutrition (fetal atrophy), which is very frequent in this population.

Health professionals concerned with improving the nutritional status of populations are facing numerous problems ranging from emaciation to overnutrition. This review article addresses the complexity, the relative significance and the interaction of factors leading to the nutritional profile of specific groups and individuals. When availability of food is threatened, the programs designed to reduce the incidence of malnutrition must balance the food supply with energy resources and population needs as well as encourage economic improvement of food distribution systems. For those persons having access to an abundant food supply, social forces and technological factors may affect food patterns, resulting in unbalanced diets associated with chronic diseases. Misinterpretation of reliable scientific findings is a major cause of abnormal nutrition behaviour. Overreaction to health messages may precipitate such conditions as anorexia nervosa or nutrient toxicity. Adverse food reactions, real or imagined, lead to restrictions in food selection. Excessive austerity in food use negates the pleasure of eating, a useful mechanism in food choice ensuring food diversity.

Reduced serum concentrations of nutrients like iron, zinc and folates and of albumin and cholesterol are found, as well as emaciation, both in malnutrition and in cancer. In patients with leukemia, a depletion of intracellular potassium and hypo-potassemia are found in addition. The use of hyperalimentation in cancer was originally based on the concept that too little food is the cause of these disturbances in the nutrition state. However, there is also a disturbed metabolism of nutrients in patients with tumors and inflammatory disease. In the case of folic acid, the disturbed metabolism could not be normalized by hyperalimentation. The more advanced the disease, the more pronounced is the disturbed nutrient metabolism, and this disturbance is related to the macrophage activity. It is not self-evident, therefore, that hyperalimentation can normalize the nutritional state in cancer. Emaciation in cancer patients is not caused exclusively by malnutrition.

A retrospective was designed to analyse the mode of presentation, clinical signs and haematological and biochemical abnormalities in 225 consecutive Black (Zulu) patients who were admitted to a general medical ward between the years 1970 and 1981 and in whom cirrhosis was later diagnosed. The most common presenting complaint was swelling of the body (60% of the patients), followed by abdominal pain (32%) and episodes of bleeding, mainly from the gastrointestinal tract (19%). On examination, hepatomegaly was encountered in 66% of the patients, with moderate to massive enlargement in 40%. Ascites was detected in 56%, with tense abdominal distension in 34%. Jaundice was present in 38% and emaciation, mental disturbance and splenomegaly in over 25%. Spider naevi (found in 2 patients) and Dupuytren's contracture (found in 1) were very rare. Thrombocytopenia and a high ESR were common. Over 90% of patients had low albumin and high globulin concentrations (albumin less than 20 g/dl and globulin greater than 60 g/dl in 25%). Bilirubin and alkaline phosphatase levels and the prothrombin index were found to be within normal limits in 32%, 24% and 52% of cases respectively. Histologically the lesion was most commonly micronodular (73%) with variable deposits of fat and iron. Peritoneoscopy was the most useful special investigation in the diagnosis of cirrhosis, leading to a correct diagnosis in 77% of cases. In conclusion, the clinical signs, biochemical abnormalities and histological features suggest that the factors causing cirrhosis in the community studied are mixed; it may result from the combined effects of alcohol abuse, malnutrition and chronic viral (e.g. hepatitis B) infections.

We report severe cases of pulmonary tuberculosis with respiratory failure who required mechanical ventilation. Of 99 patients with pulmonary tuberculosis admitted to Daido Hospital from November 1991 to November 1993, 6 patients had been mechanically ventilated. Four of these 6 patients were vagrants and had long delay from onset of the symptom to the admission. Chest X-rays of ventilated patients showed bilateral, extensive shadows consistent with those of typical pulmonary tuberculosis, and a large number of acid-fast bacilli were detected in their sputa. Though all ventilated patients except one HCV carrier had no underlying disease, they showed remarkable emaciation and malnutrition. They also showed weak PPD-skin reactions and reduced number of lymphocytes that suggested immunological disorders. Four cases have recovered, so we conclude that mechanical ventilation is necessary and useful for the treatment of severe cases of pulmonary tuberculosis.

In order to investigate whether so-called risk factors relating to treatment difficulty are true risk or not, treatment results of 520 in-patients originally treated for pulmonary tuberculosis during 12 years' period from 1980 to 1991 in our hospital were analyzed. The proportion of cases with so-called risk factors among total 520 cases was as follows: Aged patients (70 years of age and over) 31.5%. Cases discharging abundant bacilli in sputum (Gaffky scale VII or above or culture, +3 positive) 29.4%. Adverse reactions to drugs 18.1%. Far advanced cavitary lesions (GAKKAI Classification I or II3) 15.6%. Relative risk of various risk factors in cases of group A (died of tuberculosis), group B (showed delay in the negative conversion of bacilli; namely, cases converted to negative only 4th month of treatment or later) and group C (cases of groups A and B) were calculated comparing with cases of the control group (pretreatment negative bacilli cases or cases converted to negative within 3 months). In cases of group A died of tuberculosis, the results were as follows; pretreatment abundant bacilli discharge 3.1, far advanced cavitary lesions 4.6, emaciation and/or malnutrition 5.1. Other risk factors identified were the following; unhealthy life style 4.0, severe gastrointestinal tract disease 3.9, impaired pulmonary function 3.3, complicated infections 3.2, cerebrovascular injuries including psychosis and nervous system diseases 2.3, diabetes mellitus 2.0, and the adverse reactions to drugs 1.9. In cases of group B showing delay in the negative conversion of bacilli, significant risk factors were pretreatment abundant bacilli discharge, far advanced cavitary lesions, emaciation and/or malnutrition and diabetes mellitus.(ABSTRACT TRUNCATED AT 250 WORDS)
