RESUMO
Duck plague is an acute highly contagious disease of duck, geese and swan of all ages caused by Anatid Herpesvirus-1. The disease is characterized by significant decrease in growth, egg production and sudden death along with high morbidity and mortality which results into significant economic losses in duck industry. In present study, the pathology of wild strain (DP/As-Km/0019) of duck plague virus (DPV) was experimentally studied in 2 months old ducklings. The prominent clinical signs observed were depression, loss of appetite, greenish diarrhoea, ruffled feathers, nasal discharge, lacrimation and pasted eyelids with periorbital ring formation. The significant gross lesions were observed in spleen, oesophagus, liver, heart, brain and intestine. Vascular and degenerative changes like congestion, haemorrhages, necrosis and diphtheritic membrane formation were noticed in various parenchymatous organs. Microscopically, focal to diffuse areas of haemorrhages, coagulative necrosis, and fatty changes in liver, focal emphysema in lungs, formation of diphtheritic membrane on the mucosal surface along with presence of numerous infiltrating cells in oesophagus were recorded. Presence of Anatid Herpesvirus-1 viral DNA in liver and spleen tissue samples was detected by PCR.
RESUMO
Visceral leishmaniasis (kala-azar) continues to be a major rural public health problem in Bangladesh. A cross-sectional study was carried out in two subdistricts of Mymensingh district from January 2006 to June 2007 to evaluate the delay kala-azar treatment. Suspected patients who attended to out patient department (OPD) were subjected to a dipstick test (RK39) for kala-azar. Sixty five from Bhaluka and 60 positive patients from Gafargaon subdistrict were enrolled. Most of the patients (80%) first visited nonqualified private practitioners, while only 15.2% consulted registered doctors. Fifty per cent were referred to the Upazilla health complex (UZHC) by the family members or relatives. About 49% and 43% patients required third and second health-care providers for kala-azar treatment, respectively. Patient delay ranged from 2 to 30 days; median 4 (IQR 3 to 7 days), the system delay ranged from 0 days to 225 days; median 54 (IQR 40–66 days). Residential status (p value <0.05) had impact on patient delay. Educational status and number of treatment providers had impact on system delay (p<0.05). System delay rather than patient delay is the important weakness of the kala-azar control programme in Bangladesh. Residence in rural areas, low educational background and treatment providers are associated with these delays. A proper educational programme may reduce the delay.
RESUMO
Hepatobiliary diseases are frequently associated with abnormalities of the skin, nails and hair. This study was undertaken to determine the cutaneous manifestations of chronic liver disease [CLD] and particular pattern associated with aetiology of disease. Patients suffering from chronic liver disease of any aetiology presenting to department of gastroenterology Hayatabad Medical Complex, Peshawar from 1st December 2004 to 30th April 2005 were enrolled in the study. All the relevant details regarding history and clinical examination were recorded on a specially designed pro forma. A total of fifty patients, 32 males and 18 females were included. Thirty [60%] patients were suffering from chronic hepatitis C virus infection, 14 patients were suffering from Chronic hepatitis B virus infection and 2 patients each were suffering from primary biliary cirrhosis and Wilson's disease. In two cases the aetiology could not be ascertained. Different manifestations included pigmentation [82%], Terry's nails [80%], xerosis and excoriations [72%], nonscarring hair loss from axilla and pubic region [64%], and spider naevi and palmar erythema [36%]. Lichen planus was seen in 4%, vitiligo and hepatocutaneous syndrome in [2%] of patients each. Cutaneous manifestations in chronic liver disease are non-specific and do not point towards specific aetiology. Physicians caring for patients with chronic liver disease should pay attention to its multisystemic nature
