To evaluate coagulation and fibrinolytic parameters after total joint arthroplasty (TJA) and provide evidence for optimization of timing of perioperative anticoagulation medicine.

The prospective study was conducted at the Jishuitan Hospital of Peking University from January to April in 2016, and comprised patients who were scheduled consecutively to undergo primary total knee arthroplasty (TKA) or total hip arthroplasty (THA). Blood samples were obtained at day 1 preoperatively and day1, day 3 postoperatively. Antigenic levels of protein C (PC), endothelial protein C receptor (EPCR), tissue factor pathway inhibitor (TFPI), antithrombin III (AT-III), plasminogen activator inhibitor 1 (PAI-1) and tissue plasminogen activator (tPA) were measured with commercially available enzyme-linked immunosorbent assay kits.

Postoperative levels of coagulation parameters TFPI and AT-III were increased compared to preoperative values (118.7±34.6 vs 70.0±20.5 μg/ml for AT-III, and 26.37±7.91vs 16.68±8.92 μg/l for TFPI), while postoperative levels of coagulation parameters PC and EPCR were decreased (0.88±0.30 vs 2.03±0.66 μg/ml for PC, and 100.8±31.0 vs 199.4±57.4 μg/ml for EPCR). Postoperative levels of fibrinolytic parameter tPA was increased compared to preoperative values (2.87±0.83 vs 2.03±1.03 μg/l), while its specific inhibitor PAI-1 was decreased (0.88±0.30 vs 2.03±0.66 μg/l).

These results demonstrated the perturbation of the coagulation and fibrinolytic system of patients undergoing TJA. Hypercoagulation and hyperfibrinolysis were observed in postoperative patients, which suggested anticoagulant therapy is effective and necessary.

This project aimed at determining time-dependent ultrastructural and haematological changes taking place in blood stored in local blood banks of Khyber Pakhtunkhwa.

It was a longitudinal study with repeated measures design. Twenty healthy blood donors participated in this study. An amount of 250ml blood was collected from each donor and stored in Citrate Phosphate Dextrose Adenine-1 (CPDA-1)- containing blood bags. Within first four hours, baseline samples were taken while subsequent samples were obtained at 5 days interval till day 20th. Structural changes in RBCs were observed under light and scanning electron microscope (SEM) at different intervals. learn more Furthermore, haematological parameters and osmotic fragility were also determined.

Remarkable alterations were seen in RBCs morphology. From 5th day onwards, multiple visible spicules were observed on the RBC's outer membrane and more than 2/3rd cells were abnormal at day 20. There was a significant reduction in RBCs count and haemoglobin concentration while the remaining parameters remained unchanged. Osmotic fragility increased significantly over time, with <1% haemolysis noted in baseline samples as compared to 2.4% haemolysis on day 20th (p≤0.0001).

Prolonged storage of blood results in distorted RBCs morphology and increased fragility. Transfusion of such cells would potentially result in rapid lysis in patients with hepatosplenomegaly and conditions requiring multiple blood transfusions.

To determine the clinical presentation, aetiology and outcome of pancreatitis in paediatric population.

The retrospective study was conducted at Shifa International Hospital, Islamabad, Pakistan, and comprised data of children with pancreatitis presenting between 2013 and 2018. Medical records were reviewed and findings of clinical, laboratory workup and management were noted on a specifically developed proforma. Data was analysed using SPSS 23.

Of the 51 subjects, 28(54.9%) were boys. The overall mean age was 10.6±4.9 years. The most frequent clinical symptom was epigastric pain 39(76.5%). The most common aetiology was gallstones/pancreatic stones 19(37.25%). Mean hospital stay was 5.1±1.8 days, and it was longer in children aged up to 5 years compared to older children (p<0.05). Acute pancreatitis was seen in 23(45.09%) patients, followed by recurrent 19(37.25%) and chronic 9(17.64%). There was no mortality.

Timely diagnosis and prompt management of haemodynamic status could lead to successful recovery without any serious complications in paediatric pancreatitis.

To find the frequency of core binding factor acute myeloid leukaemia in our population, and to determine its association with morphological subtypes.

The retrospective study was conducted at The Indus Hospital, Karachi, and comprised data of patients aged 1-17 years who were diagnosed with acute myeloid leukaemia from July 2013 to June 2017. Data was analysed using SPSS 21.

Of the 237 patients, 137(58%) were males and 100(42%) were females. The overall mean age was 8±4.34 years. Cytogenetic testing had been performed in 212(89.45%) cases, and core binding factor was detected in 72(34%) cases. There was significant difference between the mean values of white cell count and the subtypes (p=0.000). Also the difference between core binding factor and the subtypes was significant (p=0.000).

There was found to be a significant association of core binging factor with specific subgroups of acute myeloid leukaemia.

The aim of this study was to describe and identify clinical presentation of primary immunodeficiency disorders (PIDs). Characteristic quantitative and qualitative immunological abnormalities have been described which help in establishing a definitive PID diagnosis.

This was a cross sectional study conducted in the Immunology department of the Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from Jan 2016 to Dec 2018. Sixty patients of different PIDs including humoral defects, combined immunodeficiency, phagocytic defects and other miscellaneous disorders, were diagnosed over a period of 3 years in our institute. Their clinical presentation and laboratory data are presented in this study.

In 3 years, 40 (66%) males and 20 (33%) females were diagnosed, with 13 (21.6%) patients of humoral deficiency, 22 (36.6%) of severe combined immunodeficiency, 18 (30%) of phagocytic defects and 7 (11.6%) of other miscellaneous disorders. Maximum patients belonged to Punjab province, i.e., 23 (38.3%). Their mean age for initiation of symptoms was 7±12.
