The present study describes the frequency of Foot and Mouth Disease (FMD) virus serotypes (O,A and Asia-1) in major regions (all provinces) of Pakistan using Indirect Sandwich ELISA.Also,spatial distribution of various FMD serotypes and their comparison is discussed.A total of 590 samples (Epithelial tissue) have been analyzed during a period of five years (2005-2009).Out of 590 samples,180 were found positive,giving an overall confirmation of FMDV about 33.2 %.Of the prevalent serotypes,FMDV ‘O’ serotype caused most outbreaks (20.7 %),followed by serotype A (6.6 %) and serotype Asia-1 (4.6 %) while there was no positive case oftype ‘C’.The study clearly showed that the disease was more frequent in the agro-climatic zones than in hilly areas.Based on the data of 590 samples (>50 outbreaks),the overall prevalence of FMDV in cattle and buffaloes in Pakistan was 33.2 %,while in cattle alone,it was 37.1%,higher than in buffalo (28.7 %).There were eight cases of mixed serotypes infection,indicating the presence of endemic state of disease.Another significant feature was the change over time.In phase-I (2005-2007),there was an overall prevalence of 29.4 %,while the occurrence of the serotype O,A and Asia-1 was 20.4 %,2.9 % and 4.7 %,respectively.During phase-II (2008-2009),the overall prevalence was 59.21%,while those of serotype O,A and Asia-1 were 22.4 %,31.6 % and 4.0 %,respectively.This clearly indicated a shift from serotype O to A,which may help to explain the occurrence of more severe outbreaks,despite vaccination.

OBJECTIVETo assess the therapeutic results of open reduction and internal fixation with crossed K-wires via lateral approach for displaced supracondylar fractures of the humerus in children.
METHODSWe prospectively followed 52 children who presented with Gartland type 3 displaced supracondylar fractures of the humerus and were managed by open reduction and internal fixation with crossed K-wires via lateral approach.There were 37 male and 15 female patients; average age was 7.39 years. The most common mechanism of trauma was fall while playing (n=23), followed by fall from height (n=20), road traffic accidents (n=5) and fall from standing height (n=2). In 2 cases, mode of injury was not available. The mean follow-up was 12 months and patients were assessed according to Flynn's criteria.
RESULTSLateral approach provided an excellent view of the lateral column between two nervous planes and enabled an anatomical reduction in all cases. Immobilizing the elbow at 90 degrees or more of flexion was not needed after cross K-wire fixation. Majority of patients regained full range of motion within 6 weeks of pin removal. Two patients had postoperative ulnar nerve injuries that resolved after pin removal. The common late complication of cubitus varus was not seen in any patient. Delayed presentation to the emergency department, repeated manipulations by bone setters and massage with edible oil were responsible for stiffness in 5 patients. Superficial pin tract infection was noted in 5 patients that resolved with dressings and antibiotics. No deep infection occurred. A detailed clinical examination and radiographic analysis was done at final follow-up. They included measurement of carrying angle and range of movements of both operated and normal sides, and radiographs of both upper limbs for comparison. According to Flynn's criteria, 90.4% patients showed satisfactory results.
CONCLUSIONLateral approach for open reduction and internal fixation of the widely-displaced supracondylar fracture of the humerus is safe and straightforward, ensuring anatomical reduction and excellent function. The approach is easy and familiar to most orthopedic surgeons in our setup.

Poultry farming not only provides high nutritious food but also creates employment
opportunity for rural masses. Documented evidences elaborates that helminth parasitism is
most deciduous problem of chickens especially in developing world. Ascaridia (A.) galli, a
nematode of small intestine, has been considered as the most common and important parasite
of chicken. The present study was carried out to investigate prevalence and severity of A.
galli in White Leghorn layers (housing type: battery cage and deep litter, 50 each) and
Fayoumi-Rhode Island Red crossbred (male and female: 50 each) flock rearing at Government
Poultry Farm, Dina, Punjab, Pakistan. Two hundred faecal samples were examined by using
standard parasitological and McMaster egg counting technique. The overall prevalence was
24.5% at farm, 13% in White leghorn layer (battery cage=2%, deep litter=24%) and 36% in
Fayoumi-Rhode Island Red (male=34%, female=38%). It was also observed that White leghorn
layer rearing in deep litter had more severe infection (EPG=1920) of A. galli compare with
battery cages birds (EPG=500). Parasite prevalence was significantly related with sex (P<0.05)
in Fayoumi-Rhode Island Red and male birds had less number of average parasites (0.34±0.47)
as compared to females (0.38±0.490). Additionally, female birds were under serious threat of
infection (EPG=2270) compared with its counterpart (EPG=1250). Given the high infection
rates, particular attention should be paid to management and provision of feed supplement to
White leghorn layer housing in deep litter and female bird of Fayoumi-Rhode Island Red
crossbred.
