Feral dogs in Chitral gol national park, Pakistan: a potential threat to the future of threatened Kashmir Markhor (Capra falconeri cashmiriensis) / Cães ferozes no parque nacional Chitral gol, Paquistão: uma ameaça potencial para o futuro do Markhor da Caxemira ameaçado (Capra falconeri cashmiriensis)

Feral dogs are well-organized hunters of ungulates in many parts of the world, causing great damage to wildlife populations and ultimately to the ecosystem. In Pakistan, the impacts of feral dogs on the wildlife have not been documented yet. In a period of fifteen years (2006-2020), feral dogs have killed hundreds of threatened markhor in Chitral gol national park (CGNP), Pakistan. Despite direct predation other impacts including disturbance and competition with other natural predators, could compromise conservation and management efforts. The population of feral dogs seems to have been increased with the increase of dumping sites by communities. Our findings suggest that there are pressing needs of controlling the feral dogs population and eradicating them from the core zone of CGNP and surrounding buffer communities. Conventional culling of dogs should be coupled with modern techniques like castration and sterilization. Communities should be educated regarding the clean environment, proper disposal of home wastes and, biodiversity conservation.

Psoas abscess-like metastasis from transitional cell carcinoma of urinary bladder.

We report a 70-year-old male who presented with gross painless total haematuria associated with persistent left hip pain of one month duration. Computerised tomography of abdomen revealed a mass on the right lateral wall of urinary and abscess like lesion in the left psoas. He underwent transurethral resection of bladder tumour and ultrasonographical guided tru-cut biopsy of psoas lesion. Histopathology confirmed transitional cell carcinoma with metastasis to left psoas muscle. The presentation highlights the clinical and radiological features along with review of literature of rare metastatic site from transitional cell carcinoma of urinary bladder.

Solitary delayed contralateral testicular metastasis from renal cell carcinoma.

We report a 60 year old male presenting with contralateral testicular metastasis 7 years following radical nephrectomy for renal cell carcinoma. Testicular metastases from renal cell carcinoma reported in literature are predominantly ipsilateral and invariably on the left side. Usually these are present simultaneously with the renal primary or precede the diagnosis of renal tumors. Delayed contralateral testicular metastatic has not been reported to the best of our knowledge. The case highlights the unique behaviour of renal cell carcinoma with an unusual site of recurrence. The clinical presentation, pathogenesis and management of this rare presentation along with review of recent literature are discussed.

Diagnosis and management of duodenal obstruction due to renal cell carcinoma.

Two cases of duodenal obstruction secondary to renal cell carcinoma are described. One case had delayed metastasis to duodenum four years after right radical nephrectomy and the second case had a large right renal cell carcinoma with duodenal involvement. The possibility of duodenal involvement or metastasis should be kept in mind in any patient presenting with upper gastrointestinal obstructive symptoms and with right sided renal tumour or radical nephrectomy in the past. Whenever suspected, radiography and if required endoscopic assessment should be supplemented to diagnose this condition. Extensive local disease or presence of concurrent metastasis usually rules out the possibility of cure. We describe the clinico-radiological features of this condition along with a review of the literature.
