Laboratory examination of all birds that were culled or died during an eight-month period in two commerical laying flocks was performed to reveal the causes of disease and their prevalence. The average weekly total of diseased birds was greater in one flock (60-69) than the other (27-37). This resulted mainly from a high incidence in the former flock of leucoses and sarcomas, although losses due to fatty liver syndrome, prolapse and cannibalism and cage layer fatigue were also marginally greater in this flock than the second. Haemangiomas occurred more frequently in the flock with the higher disease level. A total of 273 hens of the 2,000 examined from this flock had single or multiple haemangiomas. Special features of the major causes of disease were outlined and discussed. A conclusion made from this study was that histopathological examination is necessary for accurate diagnosis of avian tumours.

Five cases of acute fatty liver of pregnancy are described. These are the only recognized cases of this disorder occurring in a 2 year period in Western Australia. Clinical and laboratory features are presented. There was no maternal death. Of the six babies, there were three intrauterine deaths, including the only set of twins. All the babies were male. Vomiting in the third trimester was the chief presenting feature in all cases, often accompanied by a systemic illness with malaise and tiredness. Extreme polydipsia was noted as a prominent symptom in all cases. The combination of moderately abnormal liver function tests, extreme leucocytosis with other blood film abnormalities, hypoglycaemia, impaired renal function, coagulopathy and gross elevation of uric acid level is regarded as highly suggestive of the diagnosis. Features of a preeclamptic illness were present in several cases. Three of the patients have since had uneventful pregnancies. The constellation of clinical and laboratory features is sufficiently characteristic to allow accurate clinical diagnosis in most cases of this disorder. The chances of both maternal and fetal survival are enhanced by early diagnosis allowing intervention in the form of prompt delivery of the infant.

We treated a patient with idiopathic fatty liver of pregnancy and a subsequent uncomplicated pregnancy. She experienced general fatigue, nausea, vomiting and jaundice, and renal failure occurred in the third trimester of her first pregnancy. Liver biopsy revealed swollen hepatocytes with microvesicular changes in the cytoplasm. A diagnosis of idiopathic fatty liver of pregnancy was made. Following delivery of a dead fetus, she recovered completely and was discharged on the 30th hospital day. Eighteen months later, she became pregnant again and was delivered of a healthy male baby in the 39th week of gestation. Total bilirubin and transaminase levels were normal, and renal function tests revealed no significant changes during the course of the pregnancy. However, cholinesterase activity increased progressively from the 7th month, thereby suggesting a predisposition to idiopathic fatty liver of pregnancy.

We present two cases of systemic lupus erythematosus (SLE) associated with both Basedow's disease and fatty liver. The first case is a 46-year-old Japanese female who was admitted because of high fever and general fatigue. She had been diagnosed as having Basedow's disease and treated with thiamazole for over 4 years. Since thiamazole-induced lupus was unlikely because of high titer anti-nuclear antibody and anti-DNA antibody and low levels of complements, a diagnosis of SLE was made. The upper abdominal ultrasound study and the specimen obtained by liver biopsy performed before initiating steroid therapy demonstrated marked fatty liver. SLE itself is considered as an etiology of fatty liver in this case. The second case was a 25-year-old Japanese female with SLE. She had been treated with prednisolone for 13 years and was complicated with Basedow's disease 10 years later. Fatty liver was also demonstrated in this patient on ultrasonography, and was thought to be resulted from long-term steroid hormone administration.

Excessive specialization and high production requirements place high demands on the metabolism of poultry. A number of metabolic problems, such as disturbances of energy metabolism (affecting mainly hens) and mineral balance (affecting mainly laying hens), affect performance. Nearly all these problems are multifactorial in nature, but diet, and in particular the interaction between diet and phenotype, plays an important role. The problem of ascites in broiler hens is discussed in relation to external and genetic causative factors. Genetic factors can be further subdivided into structural and functional causative factors. This distinction has important consequences. For example, sudden death syndrome can be distinguished as a separate entity. Fatty liver syndrome in laying hens, and gout and urolithiasis in chicks and hens are briefly discussed. Finally, some of the most important or most common skeletal problems affecting poultry, namely, tibial dyschondroplasia, battery fatigue, rickets, and chondrodystrophy, are briefly discussed in the context of the dietary factors that underlie these disorders or which can be used as treatment.

Recently, several class-related adverse events have been recognized with antiretroviral drugs. For nucleoside analogue reverse transcriptase inhibitors. (NRTI), lactic acidosis with hepatomegaly and hepatic steatosis have been reported. These appear to occur at a low frequency, but with a high fatality rate. We report a case of fatal lactic acidosis in a patient with acquired immunodeficiency syndrome (AIDS) treated with stavudine (d4T), lamivudine (3TC) and indinavir (IDV). A 48-year-old male AIDS patient was admitted with complaints of general fatigue and dyspnea. His medications at presentation included d4T, 3TC and IDV. Physical examination demonstrated icteric sclerae and abdominal tenderness with hepatomegaly. Laboratory data demonstrated a severe metabolic acidosis with an anion gap due to lactate accumulation. Despite intensive treatment, cardiorespiratory arrest occurred and this could not be resuscitated.

Nonalcoholic steatohepatitis (NASH) is a histological diagnosis applied to a constellation of liver biopsy findings that develop in the absence of alcohol abuse. Steatosis, a mixed cellular inflammatory infiltrate across the lobule, evidence of hepatocyte injury and fibrosis are the findings that can be seen. This entity is often identified during evaluation of elevated aminotransferases after exclusion of viral, metabolic and other causes of liver disease. Obesity is a major risk factor for NASH. The role of diabetes is less certain, although evidence is accumulating that hyperinsulinism may play an important pathophysiological role. Patients sometimes suffer from right upper quadrant abdominal pain and fatigue; examination may reveal centripetal obesity and hepatomegaly. Although patients are often discovered because of persistent aminotransferase elevations, these enzymes can be normal in NASH. When they are elevated, the alanine aminotransferase level is typically significantly greater than the aspartate aminotransferase level. This can be particularly helpful for excluding occult alcohol abuse. Imaging studies identify hepatic steatosis when the amount of fat in the liver is significant; however, imaging does not distinguish benign steatosis from NASH. Ultimately a liver biopsy is needed to diagnose NASH. The biopsy may be useful for establishing prognosis based on the presence or absence of fibrosis and for excluding other unexpected causes of liver enzyme elevations. Weight loss is the mainstay of treatment for obese patients. About 15% to 40% of NASH patients develop fibrosis; how many of these cases progress to cirrhosis is unknown, but about 1% of liver transplants are performed with a pretransplant diagnosis of NASH.

We present clinical descriptions, metabolic features, and patterns of body fat loss of 16 patients with acquired generalized lipodystrophy (AGL) seen by us over the last 10 years. In addition, we review 63 cases of AGL reported in the literature. Based on these data, we propose new diagnostic criteria for AGL, the essential criterion being selective loss of body fat from large regions of the body occurring after birth. We also propose a subclassification of AGL into 3 varieties, type 1, the panniculitis variety; type 2, the autoimmune disease variety; and type 3, the idiopathic variety, which affect nearly 25%, 25%, and 50% of patients, respectively. Most of the patients presented in childhood and adolescence. Females were affected approximately 3 times more than males. Subcutaneous fat loss was severe and usually affected the face, trunk, abdomen, and extremities. In some patients, fat loss also involved the palms and soles and intraabdominal region; however, the bone marrow and retroorbital fat were preserved in all patients. Clinically, patients may have voracious appetite, fatigue, and acanthosis nigricans. Hepatomegaly was common, mostly due to hepatic steatosis. Most AGL patients had fasting and/or postprandial hyperinsulinemia, diabetes mellitus, hypertriglyceridemia, and low serum levels of high-density lipoprotein cholesterol, leptin, and adiponectin. Diabetes mellitus and hypertriglyceridemia were less prevalent in the panniculitis variety compared with the idiopathic and autoimmune varieties. The management of AGL includes cosmetic surgery for loss of fat. Severe hypertriglyceridemia should be treated with a very low-fat diet and omega-3 polyunsaturated fatty acid supplementation from fish oils. Management of diabetes is difficult and may necessitate insulin therapy in large doses. Insulin sensitizers such as metformin and thiazolidinediones have been used, although their long-term efficacy and safety remain unknown. Subcutaneous administration of recombinant leptin in AGL patients with hypoleptinemia effectively improves hyperglycemia, hypertriglyceridemia, and hepatic steatosis. Leptin therapy, however, remains investigational. Fibrates alone or in combination with statins may be used to treat hypertriglyceridemia.

Nonalcoholic fatty liver disease is a condition gaining increasing recognition as a cause of cirrhosis and end-stage liver disease. The condition appears identical to alcoholic liver disease histologically, yet occurs in patients with negligible alcohol intake. Nonalcoholic fatty liver disease covers a spectrum of diseases ranging from simple fatty deposition in the liver to fat and inflammation and finally to fibrosis and cirrhosis. Conditions most frequently found in association with nonalcoholic fatty liver disease include obesity, Type 2 diabetes, and hyperlipidemia. Although the exact etiology of nonalcoholic fatty liver disease is not clear, insulin resistance is thought to play an important factor. Patients typically present with asymptomatic serum aminotransferase elevations of 2-3 times normal. Symptoms may include fatigue and abdominal pain. The clinical course is difficult to predict due to a lack of research in the natural history of the disease. It is known a percentage of patients progress to end-stage liver disease and may require liver transplantation. No medical treatment has been found to be totally effective. Patients who are overweight or obese should be encouraged in gradual weight reduction that has been associated with improvement in liver test abnormalities.

Muscular fatigue may result from HIV infection, and may be associated with antiretroviral drug treatment. Clinical features linked to muscle biopsy findings may assist in determining etiology, and guide treatment decisions. This case series examined HIV patients in an ambulatory HIV clinic who received antiretroviral therapy, and complained of unexplained muscular fatigue. Clinical features with measurement of acid-base status, levels of lactate, aminotransferases, triglycerides and creatine kinase were correlated to light and electron microscopic results of muscle biopsy. Three patients with acquired mitochondrial changes on biopsy shared common features of lactatemia, elevated aminotransferases and triglycerides, and ultrasonographic hepatic steatosis. A fourth patient with normal mitochondria had myositis with fibrosis, but no systemic symptoms. Biochemical parameters were unremarkable, except for a high creatine kinase. Acquired mitochondrial disease may manifest as systemic illness and muscular fatigue. Unique metabolic changes and other organ dysfunction may precede overt physical signs of HIV myopathy.
