Pathological conditions of trachea and lungs of slaughtered buffaloes were investigated in the present study. A total of 80 slaughtered buffaloes were examined individually and trachea (80) and lungs (80) were collected for histopathology from the slaughterhouses of Barisal sadar, Barisal, Bangladesh, during the period from July 2006 to March 2007. Among them 9 trachea and 30 lungs were found to be apparently abnormal in naked eye. Grossly, tracheal and lungs lesions were 11.25% and 37.5% in buffaloes, respectively. The gross tracheal lesions were petechial haemorrhages on the mucosa of trachea and lungs lesions were haemorrhage and congestion in lungs (16.25%), hard nodule formation (7.5%), cyst in lungs (6.25%), emphysematous lung (5%) and thickened pleura (2.5%). In histopathology, congestion (5%) and mild tracheitis (8.75%) were recorded as tracheal lesions. Histopathological examination of lungs noticed a number of conditions or lesions such as chronic interstitial pneumonia (3.75%), edema fluid (3.75%), broncho-pneumonia (3.75%), bronchitis (2.5%), bronchiolitis (2.5%), pneumonia-congested stage (8.75%), hydatid cyst (6.25%), fibrinous pneumonia (3.75%), healed nodule (7.5%), purulent broncho-pneumonia (1.25%), fibrino-purulent pneumonia (1.25%), subacute fibrinous pneumonia (1.25%), pulmonary adenomatosis (1.25%), pleuritis (2.5%) and hemosiderosis (3.75%). For morphological descriptions, the lesions were categorized into various types; however a single section showed intermixed of various lesions.

Paratuberculosis (PTCB) or Johne's disease (JD) caused by a slow growing acid fast bacillus Mycobacterium avium subspecies paratuberculosis (MAP), is an infectious disease of many species including humans. The disease is responsible for important economic losses to livestock industry worldwide. Although the disease is widespread, it had not been studied in Algerian sheep. In this study we inspected the presence of the infection in sheep (aged 2 years old or older) using histopathology and IS900-PCR techniques in randomly 378 tissues (ileum, ileoceacale valve and lymph nodes) and fecal samples. Gross lesions were detected in 16 (4%) of samples. Histopathological examination revealed the presence of pathognomonic lesions of JD in 61 (14%) animals. Ziehl-Neelsen (ZN) staining of tissue samples was positive in 28 (7%) cases. MAP-DNA was detected in 34 (9%) fecal samples. 14 (4%) animals were tested positive for antibodies against MAP. This study showed that not only ovine paratuberculosis present in Algeria but infected animals are excreting the bacteria in feces. This could be a significant threat for other ruminants and humans. Other studies should be carried out in order to better understand the prevalence and the molecular epidemiology of MAP in the country.

The prevalence of colibacillosis in layer chickens was studied from May to September 2007. Sixty five cloacal swabs from apparently healthy birds and 55 swabs of liver (n=15), lung (n=15) and intestine (n=25) from 30 dead birds were collected in sterile nutrient broth, with histopathological samples. Bacteria were isolated and identified. Tissue samples were studied under light microscope. Escherichia coli (E. coli) was isolated from 83% of cloacal swabs of apparently healthy chickens and 87% of samples from dead birds. Affected birds had cloudy thickened air sacs, pericarditis, congestion in the liver, lung and spleen. On histopathological examination focal necrosis in liver and infiltration of heterophils, lymphocytes and macrophages in liver and lung was found. Thickening of pericardium was found due to infiltration of reticulo endothelial (RE) cells. In duodenum, severe infiltration of leukocytes mainly heterophils, lymphocytes and macrophages was found in the sub-mucosa. DOI: 10.3329/bvet.v25i1.4614 Bangl. vet. 2008. Vol. 25, No. 1, 17-24

Background: Inducible Nitric Oxygen Synthase (iNOS) promotes the generation of NO in tissues. Its role in tumor progression and immune response is unclear. Methods: The immunohistochemical expression patterns of iNOS were studied in a series of 98 tissue samples of non-small-cell lung carcinoma (NSCLC), in parallel with the expression of hypoxia and anaerobic metabolism markers, PD-L1 and tumor-infiltrating lymphocytes (TILs). Results: iNOS is expressed by cancer cells in 19/98 (19.4%), while extensive expression by cancer-associated fibroblasts occurs in 8/98 (8.2%) cases. None of these patterns relate to stage or prognosis. Extensive infiltration of the tumor stroma by iNOS-expressing TILs (iNOS+TILs) occurs in 47/98 (48%) cases. This is related to low Hypoxia-Inducible Factor 1α (HIF1α), high PD-L1 expression and a better overall survival (p = 0.002). Expression of PD-L1, however, mitigates the beneficial effect of the presence of iNOS+TIL. Conclusions: Extensive expression of iNOS by TILs occurs in approximately 50% of NSCLCs, and this is significantly related to an improved overall survival. This brings forward the role of iNOS in anti-neoplastic lymphocyte biology, supporting iNOS+TILs as a putative marker of immune response. The value of this biomarker as a predictive and treatment-guiding tool for tumor immunotherapy demands further investigation.

Abstract Background SARS CoV-19 was declared as a pandemic by the World Health Organization (WHO), raising up challenges on various levels ranging from therapeutics to diagnostics. The conventional autopsy technique may pose a health hazard to health care workers. A minimally invasive autopsy technique can diminish this hazard. Materials and methods Between August and November 2020, 51 patients who were suffering from Covid-19 at the time of their demise were included. A novel minimally invasive ultrasound-guided technique for procuring tissue samples of major organs was employed which were thereafter subject to histopathological examination. A detailed review of the course in hospital was noted. An analysis was performed to correlate the cause of death ascertained from our minimally invasive technique with the cause of death ascertained clinically. Results There was adequate tissue sampling in 45 cases, where the minimally invasive autopsy technique confirmed the cause of death in all 45 cases (100%) and made it more specific in 5 cases (11.11%). Conclusion Minimally Invasive Autopsy is an easily reproducible technique which has the potential to strengthen the probable the cause of death with reasonable certainty while ensuring safety and ethics.

Rare Malignancy

Primary small cell carcinoma of the esophagus is a relatively rare malignancy. It is highly progressive and poorly prognostic in untreated conditions. In the western populations, the rate of primary small cell carcinoma in all esophageal cancer types is between 0.05% and 2.4%, while it is endemically increasing up to 7.6% in the eastern populations. Most of the cases are in extensive stage at the time of diagnosis. Surgery is the treatment of choice in limited stages, but treatment must be multimodal in primary small cell carcinoma of the esophagus. A 47-year-old woman was referred to our clinic with gradually increasing severe dry cough and slight difficulty in swallowing for 20 days. Chest X-ray graphy was normal, and computed tomography of the chest showed multiple mediastinal lymph nodes and hepatic metastases. Her endoscopic examination revealed an endoluminal vegetative mass between 20 cm and 23 cm of her esophagus. The case was reported as small cell carcinoma of the esophagus on histopathological examination. The case was assumed inoperable, and chemotherapy and radiotherapy were planned. We presented a rare cause of the cough and primary esophageal small cell carcinoma in this paper.
