A 13-yr-old ring-tailed lemur (Lemur catta) was evaluated for depression, anorexia, polyuria, and polydipsia. The lemur was in poor body condition and was anemic, hypoalbuminemic, and hyponatremic. Cytologic examination of aspirates of the spleen, liver, and bone marrow and histopathologic examination of liver and bone marrow biopsies revealed a disseminated round cell tumor. After euthanasia, necropsy revealed hepatomegaly, splenomegaly, and mesenteric lymphadenomegaly. Neoplastic cells were present within the spleen, liver, kidneys, multiple lymph nodes, bone marrow, lung, small intestine, pancreas, and testicle and were composed of large anaplastic round cells in a background of small well-differentiated lymphocytes. Immunohistochemical analysis revealed that the small well-differentiated lymphocytes labeled for the anti-human T-cell marker, CD3, and the large anaplastic round cells labeled with the anti-human B-cell marker, CD79a. On the basis of the immunohistochemical staining results and morphologic appearance, a diagnosis of a T-cell-rich B-cell lymphoma was made.

The "cobalt" variant of rainbow trout (Oncorhynchus mykiss) lacks most of the pars intermedia of the pituitary, and shows significant obesity with an enlarged liver and a fat accumulation in the abdominal cavity. Plasma levels of growth hormone, prolactin, and somatolactin were significantly lower in the cobalt variant than those in the normal trout. In contrast, plasma insulin level was four times higher than that in the normal. Plasma levels of total protein, free cholesterol, and triacylglycerol were higher in the cobalt, while those of glucose and fatty acids were not different from the normal levels. In the white muscle, red muscle, liver, and mesenteric fat, the cobalt showed higher contents of triacylglycerol than the normal fish. There was no significant difference in tissue contents of phosphatidylcholine between the two groups of the trout, except for that in the mesenteric fat, exhibiting significantly lower content than in the normal fish. Activity of triacylglycerol lipase in the liver in vivo was lower in the cobalt than that in the normal trout, while there was no significant difference between the two in the cultured liver slices. Desacetyl-alpha-MSH stimulated lipolysis of triacylglycerol similarly in the cultured liver slices from the normal trout and from the cobalt variant. Results from this study suggest that the lack of pars intermedia and the increased plasma level of insulin are involved in a depression of lipid mobilization and obesity in this variant of rainbow trout.

The present study reports the clinical, virological and pathological findings observed in a natural outbreak of highly pathogenic avian influenza in farmed commercial ducks. The ducks developed clinical signs, including mild respiratory distress, depression, mild diarrhoea, loss of appetite and increasing mortality (up to 12%). At necropsy, multifocal mottled necrosis was commonly found in the pancreas with splenomegaly, hepatomegaly, and swollen kidneys. Microscopically, there was necrotized pancreatitis and hepatitis, and lymphocytic meningoencephalitis and myocarditis. Influenza viral antigen was demonstrated in areas closely associated with histopathological lesion. Avian influenza virus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated virus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleavage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ... In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intravenously with the virus, and all birds died within 24 h after inoculation. This is the first report of an outbreak of highly pathogenic avian influenza with clinical signs in commercial domestic ducks in South Korea.

Homeopathic Crotalus horridus 200C was evaluated in 13 clinical cases of babesiosis in dogs, compared with another 20 clinical cases treated with diminazine. Babesiosis is an important tropical tick-borne haemoprotozoan disease in dogs clinically manifested by anorexia, dehydration, temperature, dullness/depression, diarrhoea/constipation, pale mucosa, hepatomegaly, vomiting/nausea, splenomegaly, distended abdomen/ascites, yellow coloured urine, emaciation/weight loss, and occular discharge. The diagnosis of babesiosis was based on cytological evidence of Babesia gibsoni in freshly prepared blood smears. The dogs were treated with oral C. horridus 200C, 4 pills four times daily for 14 days (n=13) or diminazine aceturate 5 mg/kg single intramuscularly dose (n=20). All the dogs were administered 5% Dextrose normal saline at 60 ml/kg intravenously for 4 days. Initial clinical scores were similar in both groups and showed similar progressive improvement with the two treatments over 14 days. Parasitaemia also improved in both groups, but haematological values showed no change. No untoward reactions were observed. It appears that C. horridus is as effective in causing clinical recovery in moderate cases of canine babesiosis caused by Babesia gibsoni as the standard drug diminazine. Large scale randomized trials are indicated for more conclusive results.

Malignant histiocytosis (MH) is a progressive systemic neoplastic proliferation of morphologically atypical histiocytes, well characterised in humans and dogs but only recently identified in the cat. In all species, liver, lung, lymph nodes, spleen and bone marrow are infiltrated by atypical histiocytes, and the disease is rapidly fatal. The purpose of this study was to describe the clinical, histological, immunohistochemical and ultrastructural findings of MH in a cat, together with the diagnostic work-up and a list of differential diagnoses. Clinical evaluation included a complete blood-cell count, serum biochemistry, urinalysis, serology and ultrasound examination. The cat had clinical signs of depression, thinness, dehydration, pale mucous membranes and tachycardia. Abdominal ultrasonography revealed generalised splenomegaly and hepatomegaly. Necroscopy showed whitish nodules, randomly scattered throughout the parenchyma in the spleen and liver. The periportal lymph nodes were greatly enlarged and the cut surface was uniformly greyish-white and translucent. Histological examination revealed pleomorphic proliferation of large round tumour cells, with numerous phagocytic vacuoles containing erytrocytes, leukocytes and haemosiderin. By immunohistochemistry, positivity for lysozyme and alpha1-antitrypsin and a scattered positivity for Mac 387 were observed. Ultrastructural features of tumour cells included cytoplasmic lipid droplets, lysosomes and phagolysosomes. MH in the cat needs to be differentiated from diffuse granulomatous disease, non-Hodgkin's lymphoma and Hodgkin's-like disease. The morphological features of the tumour cells, combined with immunohistochemical and ultrastructural observation, are consistent with a diagnosis of MH in the cat.

Central nervous system involvement is a serious complication of brucellosis; data found in the literature are generally restricted to case reports and case series. In this study we pooled the data from Turkish medical practice in order to gain a thorough understanding of the subject. A search of Turkish publications on chronic neurobrucellosis was made using both Turkish and international databases. A total of 35 publications were analyzed and 187 neurobrucellosis cases were evaluated. Headache, fever, sweating, weight loss, and back pain were the predominant symptoms, while meningeal irritation, confusion, hepatomegaly, hypoesthesia, and splenomegaly were the most frequent findings. The major complications in patients were cranial nerve involvement, polyneuropathy/radiculopathy, depression, paraplegia, stroke, and abscess formation. Antibiotics were used in different combinations and over different intervals. The duration of antibiotic therapy reported ranged from 2 to 15 months (median 5 months). The mortality was 0.5% with suitable antibiotics. Neurobrucellosis may mimic various pathologies. For this reason, a thorough evaluation of the patient with probable disease is crucial for an accurate diagnosis and proper management of the disease.

This report deals with the acute onset of an abortion outbreak and high sow mortality in one pig herd consisted of 1,200 pigs and 120 sows on Jeju Island, Korea. Affected pregnant sows showed clinical signs, including high fever, gradual anorexia, vomiting, depression, recumbency, prostration, abortion, and a few deaths. Four dead sows, five aborted fetuses from the same litter, and 17 sera collected from sows infected or normal were submitted to the Pathology Division of the National Veterinary Research and Quarantine Service for diagnostic investigation. Grossly, hepatomegaly and splenomegaly were observed in sows. Multiple necrotic foci were scattered in the lungs, liver, spleen, and lymph nodes. Microscopically, multifocal necrotizing lesions and protozoan tachyzoites were present in the lesions. Tachyzoites of Toxoplasma (T.) gondii were detected immunohistochemically. Latex agglutination showed that the sera of 7 of 17 (41.2%) sows were positive for antibody to T. gondii. The disease outbreak in this herd was diagnosed as epizootic toxoplasmosis. To our knowledge, this is the first report of porcine toxoplasmosis with a high abortion rate and sow mortality in Korea.

In late summer 2006 considerable mortality in wild and captive Passeriformes and Strigiformes was observed in Zurich, Switzerland. All animals were found in a range of 2 km(2). Observed clinical signs involved depression, ruffled plumage, incoordination, seizures and peracute death. Nutritional status was generally moderate to poor in wild birds, and variable in captive animals. Necropsy showed marked splenomegaly, a mild hepatomegaly, and pulmonary hyperemia in most animals. Histopathologic lesions were very discrete and consisted mainly of neuronal necrosis, leucocytolysis in and around the brain blood vessels, and miliary liver necrosis. The diagnosis Usutu virus (USUV) infection was established by USUV-specific immunohistochemistry and reverse transcription-polymerase chain reaction. Partial nucleotide sequence comparisons revealed>99% identity between the viruses that emerged in Zurich in 2006, in Vienna in 2001, and in Budapest in 2005. Since 2008 a significantly lower mortality was observed in wild Passeriformes, but USUV infection was confirmed for the first time beyond Zurich city limits. Indoor housing and regular treatment against ectoparasites are likely to have prevented acute USUV disease in captive Strigiformes. USUV is a mosquito-borne flavivirus causing fatalities in various avian species. After the initial European outbreaks in Austria in 2001 it appears that the virus has extended its range in Central Europe and has established a transmission cycle between local bird and mosquito species. Further episodes of increased avian mortality in the forthcoming years, with impact on wild and captive bird populations, predominantly Passeriformes and Strigiformes, can be anticipated. Furthermore, the possibility of broader dispersal of USUV in Europe during the next mosquito seasons must be considered and an increased mortality in Passeriformes and Strigiformes must be expected until protective "flock immunity" is established. Collections of valuable and endangered Passeriformes and Strigiformes, especially young of the year, should therefore be housed indoors or treated against ectoparasites at acceptable intervals between July and September each year.

Hepatic involvement is common in miliary and extra-pulmonary tuberculosis but is usually clinically silent. Therefore, it is rarely diagnosed. We report the case of a patient that presented with prolonged fever and hepatomegaly. Liver biopsy revealed non-necrotizing granulomas that led in turn to the diagnosis of generalized tuberculosis and HIV infection. The patient reported an old untreated tuberculosis and depression of the immune system provoked the reactivation of this old tuberculosis focus. We describe the clinical course of the disease and the challenges associated with the complexity of the treatment. Diagnosis of hepatic tuberculosis requires a high degree of suspicion especially in AIDS patients who show atypical presentations. However, it is a potential curable disease and good results have been obtained with the four drug regimen.

A fire disaster following LPG tanker explosion occurred at Chala bypass, Kannur, Kerala, India on August 27, 2012. The three chambered tanker with total 16tonnes (162.57 quintal) LPG collided with a road divider and exploded thrice. A total of 41 people became victims during first blast; out of which 20 died in various hospitals. Five people remained inside the house after first blast and escaped unhurt from the zone of accident before second blast. All the victims were transferred to various hospitals; of these, six were transferred to the burns unit of the Kasturba Hospital, Manipal (320km from Chala). Five (5/6) were transferred within 1-5 days at our burns unit suffered 31-72% total body surface area (TBSA) burn, none had external injuries. One (1/6) was transferred on 20th day as a follow up case of 15% TBSA burn with 4% residual raw area and diabetes mellitus. Except one, all were managed conservatively using Limited access dressings (LAD; Negative Pressure Wound Therapy). One of the patient wound bed prepared under LAD and on 41 post burn day underwent split skin grafting under LAD. Out of the six patients admitted at the burns unit, two (2/6) admitted patients expired (one due to inhalation injury and another due to sepsis with multiple organ failure). One survivor (1/4) developed sepsis related liver dysfunction with hepatomegaly but recovered well. The total hospital stay of survivors at the burns unit varied from 8 to 60 days (mean hospital stay 36.5 days). All the victims who developed psychological symptoms were treated by psychiatrists and counselled before discharge. Three of survivors developed psychological symptoms. Two of them (2/3) developed mixed anxiety-depression disorder (ICD 10 code F41.8) and one of these two showed grief reaction too (ICD 10 code F43.23). One victim (1/3) developed non-organic insomnia (ICD 10 code F51.0) and responded to counselling. The article describes the incident, mechanism of the incident, injuries sustained, author, explanations on pattern of burn and suggestions in relation to future safety measures.
