Population and risk assessment of sympatric pheasant species in Palas Valley, Pakistan.

Pheasants are declining everywhere in the world and therefore updated information about their population and habitats are important for conservation and management. The present study was conducted in the Palas Valley, District Kohistan, Pakistan in late spring (May and June) 2020 and early spring (March and April) 2021 to assess the population and anthropogenic stress. The major focus was on three sympatric pheasant species, including Western Horned Tragopan (Tragopan melanocephalus), Himalayan Monal (Lophophorus impejanus), and Koklass Pheasant (Pucrasia macrolopha). We used the "Call Count Method" for the population assessment in the field, and a questionnaire survey was conducted to document the risk assessment of local residents of the valley. The population assessments revealed that the Koklass Pheasant is more adapted to increasing anthropogenic activities and its population appeared more or less similar as 22 years ago. In the past 22 years, Western Tragopan and Himalayan Monal have lost about 40-50% of their populations. Human interference in the form of illegal hunting, deforestation, and overgrazing was found to be common in the valley. The study concludes that the Palas Valley habitat is ideal for pheasant species; however, human interference in the form of urbanization, habitat fragmentation, illegal hunting, and deforestation is occurring at a rapid pace, causing havoc in the pheasant population.

Ultrasonographic assessment of the spleen in 60 healthy sheep.

AIM: To evaluate the sonographic appearance, size, location and shape of the spleen in 60 healthy sheep. METHODS: A 7.5 MHz linear scanner was used to examine the location, extent and appearance of the spleen from the left side of the sheep, in intercostal spaces (ICS) 8-12 and caudal of the last rib. RESULTS: The ultrasonographic appearance of the splenic parenchyma was homogeneous with a thin, smooth echogenic capsule. The spleen could be visualized in intercostal spaces 9-12 in all sheep, in intercostal space 8 in 25/60 sheep (42%) and caudal of the last rib in 24/60 sheep (40%). In intercostal spaces 8-12 and caudal of the last rib the spleen was visible in 16/60 sheep (27 %). The distance from the dorsal margin of the spleen to the spinous processes of the thoracic vertebrae was greatest in the 8th intercostal space: mean 19.32 (SD 2.76) cm and smallest in the 12th intercostal space: mean 6.61 (SD 1.94) cm. The dorsoventral splenic extent was greatest in the 11th intercostal space: mean 13.69 (SD 2.2) cm and smallest in the 8th intercostal space: mean 7.13 (SD 2.5) cm. The thickness of the spleen ranged from 21 (SD 9.0) mm in the 8th intercostal space to 49 (SD 7.0) mm in the 11th intercostal space. The mean vessel diameter was 1.9 (SD 0.7) mm. Spleen size did not correlate with age, body weight, or thoracic and abdominal circumference. CONCLUSIONS: Ultrasonography is a useful, straightforward and non-invasive method for evaluation of the spleen in sheep. CLINICAL RELEVANCE: These findings provide information which can be used as a reference for sonographic spleen examination and diagnosis of splenic lesions in sheep.

Assessment and management of children aged 1-59 months presenting with wheeze, fast breathing, and/or lower chest indrawing; results of a multicentre descriptive study in Pakistan.

BACKGROUND AND AIMS: Using current WHO guidelines, children with wheezing are being over prescribed antibiotics and bronchodilators are underutilised. To improve the WHO case management guidelines, more data is needed about the clinical outcome in children with wheezing/pneumonia overlap. METHODOLOGY: In a multicentre prospective study, children aged 1-59 months with auscultatory/audible wheeze and fast breathing and/or lower chest indrawing were screened. Response to up to three cycles of inhaled salbutamol was recorded. The responders were enrolled and sent home on inhaled bronchodilators, and followed up on days 3 and 5. RESULTS: A total of 1622 children with wheeze were screened from May 2001 to April 2002, of which 1004 (61.8%) had WHO defined non-severe and 618 (38.2%) severe pneumonia. Wheeze was audible in only 595 (36.7%) of children. Of 1004 non-severe pneumonia children, 621 (61.8%) responded to up to three cycles of bronchodilator. Of 618 severe pneumonia children, only 166 (26.8%) responded. Among responders, 93 (14.9%) in the non-severe and 63 (37.9%) children in the severe pneumonia group showed subsequent deterioration on follow ups. No family history of wheeze, temperature >100 degrees F, and lower chest indrawing were identified as predictors of subsequent deterioration. CONCLUSIONS: Two third of children with wheeze are not identified by current WHO ARI (acute respiratory infections) guidelines. Antibiotics are over prescribed and bronchodilators under utilised in children with wheeze. Children with wheeze constitute a special ARI group requiring a separate management algorithm. In countries where wheeze is common it would be worthwhile to train health workers in use of the stethoscope to identify wheeze.
