A 6-year-old spayed female domestic shorthair cat with a 3-week history of inappetence, weight loss, and hiding was examined. A palpable abdominal fluid wave, dehydration, and a small tear on the left flank were noted during initial examination. When the cat was gently restrained for blood sampling, the skin on the dorsal neck tore, leaving a 15 cm x 7 cm flap of skin. Clinicopathological abnormalities included nonregenerative anaemia, hypoalbuminaemia, increased globulin concentration, and mildly elevated aspartate aminotransferase and alkaline phosphatase activities. Abdominal fluid was viscous and had a total protein of 5.3 g dL(-1) with 316 cells microL(-1), consistent with a modified transudate. Cytology of the abdominal fluid revealed 86% nondegenerate neutrophils, 13% macrophages, and 1% small lymphocytes. Histopathological evaluation and indirect immunohistochemistry confirmed a diagnosis of feline infectious peritonitis, hepatic lipidosis and feline skin fragility syndrome. Feline skin fragility syndrome has not previously been reported in association with feline infectious peritonitis (FIP). Its inclusion as a clinical sign associated with FIP may facilitate a diagnosis.

Erythrograms determined from whole blood analyses and serum analyses for aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT) and alkaline phosphatase (ALP) activities, and iron concentration, were used in infected and uninfected cattle to determine the type of anaemia and degree of hepatic damage caused by Fasciola hepatica. Blood samples from 86 infected and 30 uninfected cattle were taken at slaughter. Haematological analyses revealed decreased levels of packed cell volume (PCV), haemoglobin concentration, mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) in infected compared with uninfected cattle (P < 0.05). A decrease in the concentration of serum iron was also observed in infected cattle compared with uninfected cattle (P < 0.05). Significant increases in AST, GGT and ALP activities were observed in cattle infected with F. hepatica when compared with uninfected cattle (P < 0.05). It was concluded that the anaemia observed in cattle infected with F. hepatica is a normocytic, hypochromic anaemia and the most important aetiology of the anaemia is the chronic blood loss due to the blood-sucking activity of the adult flukes and leakage of blood from the bile duct to the intestine, which results in iron deficiency. The increased activities of serum enzymes indicated chronic hepatic and bile duct injuries associated with chronic infection with F. hepatica.

Oxidative stress is a general mechanism whereby free radicals induce oxidative damages and reduce the antioxidant defences of the biological systems. The aim of the present study was to determine plasma malondialdehyde levels as a biomarker of lipid peroxidation and its relation to the antioxidants status (plasma ascorbate and blood glutathione concentrations), liver function tests and anaemia in spontaneous ovine fascioliasis. For this purpose, jugular blood samples and livers of 27 infected ewes with Fasciola hepatica along with blood samples of 20 healthy (control) ewes were collected from animals slaughtered in a F. hepatica endemic area (Kharga oasis, Egypt). An increase (P<0.001) in plasma malondialdehyde (141.1%) accompanied by decreased levels (P<0.001) of albumin (29.3%) and ascorbate (36.2%) in plasma and glutathione in blood (31.6%) of infected sheep was noticed when compared with control values. In the infected group, malondialdehyde values were positively correlated with liver fluke burden (r=0.57, P=0.002) and the activity of plasma aspartate aminotransferase (r=0.39, P=0.0.046) and gamma-glutamyltransferase (r=0.64, P=0.0003) and negatively correlated with the concentrations of albumin (r=-0.53, P=0.004), ascorbate (r=-0.46, P=0.0.17) and glutathione (r=-0.41, P=0.034). In conclusion, oxidative stress is a significant feature of chronic F. hepatica infection in grazing sheep.

Revision surgery for loosened hip prostheses is a heavy burden for elderly patients with comorbidity. As an alternative to surgery we performed a study to stabilize the prosthesis by percutaneous cement injection after removing inflammatory tissue with an intraarticular virus-directed enzyme prodrug approach. Twelve elderly patients with debilitating pain from a loosened hip prosthesis were included in a phase 1 dose-escalating clinical study. The patients were admitted to the hospital for 10 days for an intraarticular vector and prodrug injection, and subsequently for a percutaneous bone cement injection. This paper reports the adverse and serious adverse events of the study. After prodrug injection 9 of 12 patients had gastrointestinal adverse events (nausea, vomiting, and diarrhea), and 8 patients had hepatic adverse events (rise in aspartate aminotransferase and alanine aminotransferase). Five patients developed anemia (World Health Organization grade 1 or 2) from hematomas after cement injection. There were four serious adverse events in the first 6 months after vector injection, but these were not related to gene therapy as judged by an independent safety committee. There was no dose-limiting toxicity. However, the extensive comorbidity in these patients makes it difficult to fully establish the safety of the approach in this small and heterogeneous patient population.

Hepatitis C virus (HCV) infection may deteriorate quality of life. The relationship between HCV infection and quality of life in hemodialysis (HD) patients is unknown. The demographic characteristics, comorbidities, biochemical parameters, and Malnutrition-Inflammation Score (MIS) were recorded. Child-Pugh classification, Beck Depression Inventory, and SF-36 were performed. Liver histopathology was examined. Thirty-two patients (21 Child-Pugh-A, 11 Child-Pugh-B) were included. There was high-grade portal necroinflammatory activity in 14, high-grade lobular necroinflammatory activity in 26, and hepatic fibrosis in 19 patients. Three patients had cirrhosis. Patients with a high stage of liver fibrosis had lower social functioning scores than patient with a low stage of fibrosis (P= 0.011). The only correlation was between aspartate aminotransferase and the physical function subscale (r=-0.395, P= 0.025). None of the SF-36 scores differed between Child-Pugh A and B patients. Instead, most of the SF-36 subscale and summary scores were related with hemoglobin, albumin, MIS and Beck Depression Score. Quality of life in HCV-infected HD patients was independent of liver disease severity anchors, but was correlated with anemia, malnutrition, and depression.

Risks from electromagnetic devices are of considerable concern. Electrohypersensitive (EHS) persons attribute a variety of rather unspecific symptoms to exposure to electromagnetic fields. The pathophysiology of EHS is unknown and therapy remains a challenge. We hypothesized that some electrosensitive individuals are suffering from common somatic health problems. Toward this end we analysed clinical laboratory parameters including thyroid-stimulating hormone (TSH), alanine transaminase (ALT), aspartate transaminase (AST), creatinine, hemoglobine, hematocrit and c-reactive protein (CRP) in subjects suffering from EHS and in controls that are routinely used in clinical medicine to identify or screen for common somatic disorders. One hundred thirty-two patients (n = 42 males and n = 90 females) and 101 controls (n = 34 males and n = 67 females) were recruited. Our results identified laboratory signs of thyroid dysfunction, liver dysfunction and chronic inflammatory processes in small but remarkable fractions of EHS sufferers as potential sources of symptoms that merit further investigation in future studies. In the cases of TSH and ALT/AST there were significant differences between cases and controls. The hypotheses of anaemia or kidney dysfunction playing a major role in EHS could be unambiguously refuted. Clinically it is recommended to check for signs of treatable somatic conditions when caring for individuals suffering from self-proclaimed EHS.

A 9-year-old girl developing fever and hyperemia of both bulbar conjunctiva 5 days before admission to the Saitama Children's Medical Center after antibiotics proved ineffective was found on admission to have general fatigue and a temperature of 39 degrees C. Physical examination showed hyperemia of the bulbar conjunctiva, fissures of the lips, redness of the pharynx, and swelling of the cervical lymph nodes. Laboratory tests detected neutrophilia (11,200/microL), mild anemia (11.4g/dL), thrombocytopenia (110,000/microL), and elevated serum aspartate aminotransferase (242IU/L), alanine aminotransferase (328IU/L), and C-rective protein (25.2 mg/dL). Autoantibodies such as anti-nuclear, anti-SS-A/Ro, and anti-Jo-1 were also found. Echocardiography showed no abnormality of the coronary arteries. She was diagnosed as having incomplete Kawasaki disease on day 7 of illness, necessitating that a high dose of immunoglobulin be given intravenously. Her temperature dropped temporarily to 37 degrees C, but she developed erythema of the cheek and fever. Intravenous immunoglobulin was restarted, and minocycline introduced because her daily contact with a pet cat indicated richettsial infection such as Q fever. Mild fever, muscle pain, and elevated C-reactive protein did not improve, but clinical signs and symptoms gradually lessened after ibuprofen was given, then disappeared. A definitive diagnosis of Q fever was made through an over 4-fold rise in phase II IgG antibody titers against Coxiella burnetii, titer of less than 1 : 16 on day 14 of illness, and titer of 1 : 256 on day 34. This case study describes on atypical case of Q fever with clinical manifestations mimicking Kawasaki disease.

This paper describes three cases of liver lobe torsion in rabbits presenting with anorexia, lethargy, jaundice and abdominal pain. This condition was associated with anaemia and elevation of alanine aminotransferase, aspartate aminotransferase and gamma-glutamyl transferase. Abnormal radiological findings included hepatomegaly, gas-filled intestinal loops consistent with gastrointestinal ileus and ascites. Ultrasonographic findings included heterogeneous liver parenchyma, free abdominal fluid and reduced bowel motility. Diagnosis was confirmed by histopathological examination of the liver in all three cases.

Globally, sickle cell disease (SCD) has its highest prevalence and worst prognosis in sub-Saharan Africa. Nevertheless, relatively few studies describe the clinical characteristics of children with SCD in this region. We conducted a prospective observational study of children with SCD attending a specialist out-patient clinic in Kilifi, Kenya. A total of 124 children (median age 6.3 years) were included in the study. Splenomegaly was present in 41 (33%) subjects and hepatomegaly in 25 (20%), both being common in all age groups. A positive malaria slide was found at 6% of clinic visits. The mean haemoglobin concentration was 73 g/l, compared to 107 g/l in non-SCD controls (P < 0.001). Liver function tests were elevated; plasma bilirubin concentrations were 46 micromol/l and aspartate aminotransferase was 124 iu/l. Forty-eight (39%) children were admitted to hospital and two died. Children with SCD in Kilifi have a similar degree of anaemia and liver function derangement to patients living in developed countries, but splenomegaly persists into later childhood. The prevalence of malaria was lower than expected given the prevalence in the local community. This study provides valuable data regarding the clinical characteristics of children living with SCD in a rural setting in East Africa.

Acute hepatic failure is traditionally diagnosed on the basis of clinical presentation, historical information, and a collection of abnormal laboratory findings including elevated aspartate aminotransferase, alanine aminotransferase, prothrombin time, serum bilirubin and alpha-fetoprotein. Non-specific haematological findings such as anaemia, thrombocytopenia and changes in erythrocyte morphology are well documented in patients with liver failure. It is believed, however, that there are no specific morphological findings on peripheral blood smears directly linked to liver failure. This report describes two patients diagnosed with acute hepatic failure, both having coarse, bright-green cytoplasmic inclusions identified within their neutrophils. One previous case of a patient with similar neutrophil findings and concurrent liver disease has been reported in the literature; however, a direct relationship to liver failure was not proposed. It is suggested that the findings may be directly related to liver failure and may also serve as a prognostic indicator of impending death.
