Abstract
Background Surgical site infections (SSI) are the common nosocomial infection in surgical patients, and are a significant source of postoperative morbidity resulting in increased hospital stay, morbidity and cost. Objective The objective of this study was to obtain the incidence of SSI and determine various risks factors influencing the SSI rate with special reference to the National Nosocomial Infections Surveillance System risk index in Kathmandu University Hospital, Kavre, Nepal. Method Six hundred and thirty eight patients who underwent various surgeries in Dhulikhel Hospital, Kathmandu University Hospital during a three-month period were included. Using a pre designed questionnaire with follow up to 30 days and in orthopedic cases, where metal implants were used as internal fixation devices, with follow up to 90 days data were collected. Infected cases were identified using Centre for Disease Control and Prevention definition for surgical site infections. Swabs were obtained from wounds and were processed without delay using standard microbiological methods. Result Overall SSI rate was 2.6%. The most common pathogen isolated was Escherichia coli (5 isolates, 29.4 %). The SSI rate was 0.0% for clean wounds, 2.9%, 15.3% and 18.7% for clean-contaminated, contaminated and dirty wounds respectively. Increased incidence of surgical site infections were associated with higher grades of wound, emergency surgeries, American Society of Anesthesiologists score >2 and increased in National Nosocomial Infections Surveillance System risk index. Conclusion The incidence of SSI in this study meets the standard of center for disease prevention and control. Increases in surgical wound class, National Nosocomial Infections Surveillance System risk index, American Society of Anesthesiologist score >2 and emergency surgeries were associated with increased SSI rates.

Abstract
Background Renal colic is a common emergency department presentation. Hydronephrosis is indirect sign of urinary obstruction which may be due to obstructing ureteric calculus and can be detected easily by bedside ultrasound with minimal training. Objective To compare the accuracy of detection of hydronephrosis performed by the emergency physician with that of radiologist's in suspected renal colic cases. Method This was a prospective observational study performed over a period of 6 months. Patients >8 years with provisional diagnosis of renal colic with both the bedside ultrasound and the formal ultrasound performed were included. Presence of hydronephrosis in both ultrasounds and size and location of ureteric stone if present in formal ultrasound was recorded. The accuracy of the emergency physician detection of hydronephrosis was determined using the scan reported by the radiologists as the "gold standard" as computed tomography was unavailable. Statistical analysis was executed using SPSS 17.0. Result Among the 111 included patients, 56.7% had ureteric stone detected in formal ultrasound. The overall sensitivity, specificity, positive predictive value and negative predictive value of bedside ultrasound performed by emergency physician for detection of hydronephrosis with that of formal ultrasound performed by radiologist was 90.8%., 78.3%, 85.5% and 85.7% respectively. Bedside ultrasound and formal ultrasound both detected hydronephrosis more often in patients with larger stones and the difference was statistically significant (p=.000). Conclusion Bedside ultrasound can be potentially used as an important tool in detecting clinically significant hydronephrosis in emergency to evaluate suspected ureteric colic. Focused training in ultrasound could greatly improve the emergency management of these patients.

Abstract
BACKGROUND With the development of better imaging modalities including 3D CT scan and availability of technical expertise, operative management is increasingly performed for acetabular fracture but many patients in developing countries like Nepal, are still being treated with prolonged skeletal traction. OBJECTIVE To analyses epidemiology, types of acetabular fracture and functional and radiological outcome of patients with acetabular fracture treated with open reduction and internal fixation (ORIF). METHOD Inpatients hospital records of patients treated with ORIF in between June 2007 to June 2014 were evaluated. Patient's demographic data, mode of injury, injury hospital interval, injury surgery interval, associated injuries, surgical approach, total hospital stay and peri and post-operative complications were recorded and radiological and functional outcomes were evaluated. RESULT Thirty three patients (Male: 24 Female: 9) with average age 39 years (range: 21 to 65 years) were operated for acetabular fracture. Twenty one patients (63%) had injury related with motor vehicle accidents and nine (24%) of them had motorbike accidents. Injury hospital interval ranges from 7 to 36 days. Average injury-surgery interval was 21 days and average hospital stay was 22 days. Bicolumnar fractures were found in 15. Nine patients had dislocation of hip and 15 had concomitant other injuries. Biculumanr fixation was performed in 15 patients, posterior column and or wall in nine with Kocher Langenbeck approach and anterior column and or wall in other nine with ilio-inguinal approach. Radiological reduction was anatomical in 18; excellent/good functional outcome was in 26 and radiological outcomes were excellent in 14. Three patients had developed Hypertopic ossification. Follow up period ranged from 6 to 48 months and 15 patients (45%) had follow up >2 years. CONCLUSION Acetabular fractur can be effectively managed with ORIF and have predictable and comparable functional and radiographic outcomes. Upgrading the existing facilities and training of orthopedic surgeon for acetabular fracture management is important to shorten injury-surgery interval due to lack of such facilities.

Abstract
The accurate analysis of trace component in complex biological matrices requires the use of reliable standards. For liquid chromatography/mass spectrometry analysis, the stable isotope-labeled derivatives of the analyte molecules are the most appropriate internal standards. We report here the synthesis of (2β,3α,6-(2)H3)cholesteryl linoleate and oleate containing three non-exchangeable deuterium in the steroid ring. The principal reactions used were: (1) trans diaxial opening of 2α,3α-epoxy-6-oxo-5α-cholestane with LiAlD4 and subsequent oxidation of the resulting (2β,6α-(2)H2)-3α,6β-diol with Jones' reagent, followed by reduction of the resulting (2β-(2)H)-3,6-dione with NaBD4 leading to the (2β,3α,6α-(2)H3)-3β,6β-dihydroxy-5α-cholestane, (2) selective protection of the 3β-hydroxy group as the tert-butyldimethylsilyl ether, (3) dehydration of the 6β-hydroxy group with POCl3 and removal of tert-butyldimethylsilyloxy groups with 5M HCl in acetone, and (4) esterification of the resultant (2β,3α,6-(2)H3)cholesterol with linoleic and oleic acids using 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide. The isotopic purity was found to be satisfactory by mass spectrometry, and nuclear magnetic resonance properties of the new compounds were tabulated. The labeled compounds can be used as internal standards in liquid chromatography/mass spectrometry assays for clinical and biochemical studies.

Abstract
BACKGROUND Cesarean Section (CS) is one of the most commonly performed surgical procedures in obstetrical and gynecological department. Surgical site infection (SSI) after a cesarean section increases maternal morbidity prolongs hospital stay and medical costs. OBJECTIVE The aim of this study was to find out the incidence and associated risk factors of surgical site infection among cesarean section cases. METHOD A prospective, descriptive study was conducted at Dhulikhel Hospital, department of Obstetrics and Gynaecology from July 2013 to June 2014. Total of 648 women who underwent surgical procedure for delivery during study period were included in the study. Data was collected from patient using structred pro forma and examination of wound till discharge was done. Data was compared in terms of presence of surgical site infection and study variables. Wound was evaluated for the development of SSI on third day, and fifth post-operative day, and on the day of discharge. RESULTS Total of 648 cases were studied. The mean age was 24±4.18. Among the studied cases 92% were literate and 8% were illiterate. Antenatal clinic was attended by 97.7%. The incidence rate of surgical site infection was 82 (12.6%). SSI was found to be common in women who had rupture of membrane before surgery (p=0.020), who underwent emergency surgery (p=0.0004), and the women who had vertical skin incision (p=0.0001) and interrupted skin suturing (p=0.0001) during surgery. CONCLUSION Surgical site infection following caesarean section is common. Various modifiable risk factors were observed in this study. Development of SSI is related to multifactorial rather than one factor. Development and strict implementation of protocol by all the health care professionals could be effective to minimize and prevent the infection rate after caesarean section.

Abstract
BACKGROUND Pathophysiological role for high-density lipoprotein (HDL) subclasses remains to be elucidated. Homogeneous assay for simultaneous measurements of apoE-deficient HDL-cholesterol (HDL-C), apoE-containing HDL-C, and total HDL-C is desired, because apoE plays important roles in lipid metabolism. METHODS The proposed assay consists of a primary reaction to remove non-HDL-C, a secondary reaction to measure apoE-deficient HDL-C, and a tertiary reaction to measure apoE-containing HDL-C. The assay is completed within 10 min. For control study, 13% polyethylene glycol precipitation assay and phosphotungstate-dextran sulfate-magnesium precipitation assay were carried out. RESULTS Good correlations between the control assays and the proposed assay was obtained in serum samples from patients without liver disease (n=33): r=0.987, 0.957, and 0.991 for apoE-deficient, apoE-containing, and total HDL-C, respectively. ApoE-containing HDL-C by the proposed method in healthy individuals (n=12) and patients with hyper-HDL-cholesterolemia (n=5) were 0.11±0.03 and 0.26±0.05 mmol/l (4.1±1.3 and 10.1±2.0 mg/dl), respectively. ApoE-containing HDL-C increased rapidly at >2.59 mmol/l (100 mg/dl) of total HDL-C, suggesting a unique regulating mechanism of apoE-containing HDL-C. CONCLUSIONS The established homogeneous assay might be useful for clinical and epidemiological studies on apoE-deficient and apoE-containing HDL subclasses.

Abstract
Background Neuropathic pain is one of the common complains of patients visiting neurology and orthopedic departments in hospitals. Management of neuropathic pain is difficult and is often symptomatic rather than being curative. Adherence to medication is necessary for pain management to be effective. However, there are various factors related to patient, physician, drug regimen and other socio-economic affecting adherence. Objective To study commonly prescribed drugs in neuropathic pain management and the medication adherence pattern including its associated factors. Method Patients already diagnosed as neuropathic pain were interviewed using structured questionnaire and data entered in Microsoft Office Excel 2007. Informed consent was taken from the patients. Result Among the 84 patients in the study, 69% were females. Majority 53.6% of patients had low back pain as cause of neuropathic pain. Anticonvulsants were mostly prescribed (75%) followed by non-steroidal anti-inflammatory drugs (52.4%) and Methylcobalamin (47.6%). More than 50% (n=49) patients were not adherent to the prescribed medication and majority (61.2%) of them were housewives. Significant association was observed between patient's adherence to gender, occupation, polypharmacy, drug regimen, cost and availability of medicine. Conclusion Anticonvulsants were commonly prescribed drugs in patients with neuropathic pain. Neuropathic pain was seen more in females with low back pain. Majority of patients were non-adherent and forgetfulness was the major reason for missing dose in them.

Abstract
BACKGROUND Traumatic optic neuropathy is an acute injury of the optic nerve due to trauma. It is an ocular emergency, requiring early treatment though there is no proven standard treatment protocol for the condition. Various studies have shown improvement in vision after intravenous steroids, but not statistically significant. Studies have revealed even optical decompression surgery is not the ultimate treatment because of no significant improvement of vision. Our study aims to assess visual outcome after high dose (1 gram) of intravenous methylprednisolone in cases with indirect optic neuropathy. METHODS This was a non-randomized interventional study carried out in Kathmandu Medical College Teaching Hospital from May 1st 2013- June 1st 2014. RESULTS There were 10 cases with indirect traumatic optic neuropathy included in the study. Four cases received IV methylprednisolone and six cases were observed without steroid treatment. Traumatic optic neuropathy was observed more in males[8 (80%)]with higher number in age group 21-30 years old. The visual recovery after intravenous steroid treatment was rapid and beneficial in cases with vision better than Non Perception of Light (NPL), even in cases presented 4 days after the trauma. CONCLUSIONS There was rapid and beneficial improvement in visual acuity after high dose of intravenous steroid treatment in cases with indirect traumatic optic neuropathy with vision better than Non Perception of Light (NPL).

Abstract
BACKGROUND Avian influenza (AI) is currently a threat to global health. Prevention and control of AI depends on the knowledge and preventive practices of the poultry workers as well as of general population. This study aims to assess knowledge and preventive practices related to AI among poultry workers. METHODS Cross-sectional study was carried out among poultry workers of Kamalamai Municipality, Sindhuli. Data was collected from randomly selected 122 respondents through face-to-face interview. The collected data was entered in Epi-data version 3.1 and analyzed in terms of descriptive statistics (proportion, 95% CI, mean and standard deviation) by using SPSS, version 20. A scoring system was used to assess knowledge and preventive practices. RESULTS Out of total, 93.4% (95% CI, 87.6- 96.6%) of the respondents had heard about AI. More than half (54.9%) of the respondents had poor knowledge on AI. Only 5.3% of respondents had good preventive practice against AI. 30.3% respondents had good knowledge and good practice and 24.6% had poor knowledge as well as poor practice. 20.5% of the respondents had good practice but poor knowledge, whereas, 24.6% had good knowledge but poor practice towards prevention. CONCLUSIONS The knowledge and practice of AI among poultry workers were low. The groups should be targeted for appropriate intervention based on whether they lack knowledge or practice or both.

Abstract
Background Helicobacter pylori (H. pylori) infection is the most common chronic bacterial infection worldwide affecting approximately half of the world's population. A number of screening tests as well as complex multi-drug therapies are available for the detection and treatment of H. pylori infection. However, the optimum eradication rates of H. pylori infection can only be achieved if adherence to drug therapy is higher. Therefore, it is of utmost importance to determine the factors leading to poor adherence to obtain successful treatment outcomes. Objective To determine the medication adherence pattern in patients with H. pylori infection and assess the factors associated with non-adherence to the prescribed drug therapy. Method Patients meeting the inclusion criteria who were confirmed as H. pylori positive by rapid urease test (histopathology) and/ or stool antigen test and those under H. pylori eradication therapy were considered. Informed consent was taken from the patients or from the patient party in incapacitated patients. They were then interviewed using structured questionnaire. Statistical analysis was done using SPSS version 20 and a p-value < 0.05 was considered as statistically significant. Result Among the 70 participants included in this study, 57.10% (n=40) of them were males. The mean (±SD) age of the patients was 42.36 years (±17.93). Higher number (85.70% (n=60)) of the patients were adherent to the recommended medication. Forgetfulness was the reason for missing dose in a majority (80% (n=8)) of the nonadherent patients. A highly significant association (p<0.05) was observed between adherence and absence of symptomatic relief. However, there was no statistically significant association (p>0.05) between patients' adherence to gender, age, literacy, and the prescribed treatment regimen. Conclusion Majority of the patients with H. pylori infection were adherent to medication. Forgetfulness was the major reason for missing dose in the non-adherent patients.

Abstract
Nuclear accumulation of transglutaminase 2 (TG2) is an important step in TG2-dependent cell death. However, the underlying molecular mechanisms for nuclear translocation of TG2 are still poorly understood. In this study, we demonstrated that acyclic retinoid (ACR) induced nuclear accumulation of TG2 in JHH-7 cells, a hepatocellular carcinoma (HCC) leading to their apoptosis. We further demonstrated molecular mechanism in nuclear-cytoplasmic trafficking of TG2 and an effect of ACR on it. We identified a novel 14-amino acid nuclear localization signal (NLS) (466)AEKEETGMAMRIRV(479) in the 'C' domain and a leucine-rich nuclear export signal (NES) (657)LHMGLHKL(664) in the 'D' domain that allowed TG2 to shuttle between the nuclear and cytosolic milieu. Increased nuclear import of GAPDH myc-HIS fused with the identified NLS was observed, confirming its nuclear import ability. Leptomycin B, an inhibitor of exportin-1 as well as point mutation of all leucine residues to glutamine residues in the NES of TG2 demolished its nuclear export. TG2 formed a trimeric complex with importin-α and importin-β independently from transamidase activity which strongly suggested the involvement of a NLS-based translocation of TG2 to the nucleus. ACR accelerated the formation of the trimeric complex and that may be at least in part responsible for enhanced nuclear localization of TG2 in HCC cells treated with ACR.

Abstract
Background Pelvic ring disruption when treated conservatively can be associated with prolonged hospital stay and immobilization, mal-union, chronic pain, limb length discrepancy if they are treated conservatively. Open reduction and fixation in an already compromised soft tissue and hemodynamically unstable patient causes more soft tissue injury, heamatoma, infection and neurovascular injury. Percutaneous ilio-sacral joint fixation can be an alternative technique for sacro-iliac joint injury and sacral fracture.Objective To evaluate technique and safety of percutaneous ilio-sacral screw fixation in supine position under single fluoroscopy guidance for sacral fracture and sacro-iliac joint disruption.Method Twenty one patients either with sacral fracture or sacro-iliac joint disruption with percutaneous ilio-sacral screw fixation with cannulated cancellous screw fixation in between 2008 to 2014 were retrospectively evaluated including AP, inlet and outlet views of pelvis X rays and CT scan. Tile’s classification and Dennis classification were used for pelvis and sacral injury.Result Thirty five percutaneous ilio-sacral screws were placed (Male: 6, Female: 15; range: 15 to 54) for sacral fracture involving zone 2 (8 with sacral fracture only and 5 with pelvis injury; Tile’s type B in four and type C in one) and sacro-iliac joint injury (Tile’s type B in three and type C in five). Commonest mode of injury was motor vehicle accidents (10) followed by fall related injury (6). Injury hospital interval and injury surgery interval was five hours to 13 days and 2 to 20 days respectively. Follow period was 3 months to 6 years. One patient developed post-operative deep vein thrombosis and another patient had post-operative haematoma. Two screws were juxtra-foramial. Good to excellent outcome were in 16 patients, fair in four and poor in one patient (Majeed Scoring).Conclusion Percutaneous ilio-sacral screw fixation for sacro-iliac joint injury and sacral fracture with C arm guidance is safe and minimally invasive technique. Clear images and accurate interpretation of X-rays, CT scans and per operative C arm images are important to avoid malpositioning of screws and iatrogenic neurovascular injuries.Kathmandu University Medical Journal Vol.13(1) 2015; 56-60

Abstract
Background Benign prostatic hyperplasia is a condition occurring in elderly men in which the prostate gland is enlarged, hence the condition also known as benign enlargement of prostate. Benign hyperplasia can lead to both obstructive and irritative symptoms. Transurethral resection of prostate (TURP) still remains the gold standard modality of surgical treatment of obstructive lower urinary tract symptoms due to Benign hyperplasia.Objectives The objective of this study was to evaluate the outcomes of TURP in large prostate (>80 grams) in comparison to small prostate (<80 grams) in terms of efficacy, safety and complications.Methods A total of 65 cases included in this prospective study, which were operated by a single surgeon with conventional monopolar TURP using standard technique. Intra -operative and post-operative complications, pre and post- operative quality of life (QoL) and international prostate symptom score (IPSS), operative time, time to removal of catheter and hospital stay were evaluated between small and large prostate gland volumes.Results Out of 65 cases, 30 were with large prostate size i.e. 80 grams or more (group 1), and 35 cases were with small prostate size than 80 grams size (group 2). Mean age was 71.8 SD ± 6.9 years in group 1 and 68.2 SD ± 12.7 years in group 2. The mean preoperative volume of prostate was 88.8 grams (range 80-115 grams) in group 1 and 40.3 (range 20-65 grams) in group 2. The mean preoperative post void residual volume of urine (PVRU) was 244 ml SD ± 190.8 ml in group 1 and 117 ml ± 70.3 ml in group 2. Mean resection time in group 1 was 110 (range 90-130) minutes and in group 2 it was 90 minutes (range 55-115) minutes. There were quite satisfactory improvements in IPSS and QoL. No significant complications were observed except TUR syndrome in 2 cases from group 2, which were managed well in postoperative period.Conclusion With meticulous resection and intra-operative haemostasis using continuous out flow resectoscope, conventional monopolar TURP is equally safe and effective in large size prostate as compare in small size.Kathmandu University Medical Journal Vol.12(3) 2014; 163-167

Abstract
Myiasis occurs in humans and vertebrate animals mostly due to dipterous flies of the genera Chrysomyia and Cochliomyia. There have been reported cases of myiasis of skin, breast, intestine, eyes and ear but very few cases of vulvar myiasis have been reported in the medical literature. We report a case of a 20 years old female with vulvar myiasis. A 20-year old unmarried girl presented to our hospital with complains of vaginal discharge and vulvar irritation for 3 days with evidence of some worms around her vulvar region. Her menstrual history revealed the use of folded cloths instead of sanitary pads during her menstruation. Moreover, she washed those clothes with water and hanged them in the clothesline outside to let them dry before reuse. Examination of the external genitalia multiple ulcers measuring 1X1 cm on the inner surface of the labia minora, heavily infested with large number of maggots. The patient was admitted for 4 days during which she was given antibiotics, analgesics and anti-inflammatory medication. Daily local asepsis of the wound with antiseptic solution, betadine was done. We removed more than 30 larvae by the fourth day after which no more larvae were seen and she gradually recovered in the following days. It is our opinion that the cause of vulvar myiasis in our patient was her poor sanitary hygiene. Simple measures such as washing clothes thoroughly, drying and ironing of clothes are also necessary to reduce the risk of this human myiasis.

Abstract
INTRODUCTION Forearm fractures are common upper limb injuries among children and usually treated non-operatively. Failure of non-operative treatment, open injuries and multiple fractures are the indications for surgery in paediatric both bone forearm fractures. Intramedullary nailing is considered as minimally invasive procedure with excellent to fair outcomes but it is not free of complications. We reviewed the results and evaluated the outcomes of IM fixation of forearm fractures in children by Rush nails to understand the risks and complications associated with these procedures. METHODS A retrospective crossectional study of all paediatric patients treated for diaphyseal forearm fractures for period of five years in a tertiary care setup. Complications were classified according to modified Clavien-Dindo complication classification system. Outcomes were graded depending upon complication grade along with range of motion of forearm. RESULTS A total of 25 patients were included in the study. Mean time for fracture union was 10.56 weeks. Outcomes were excellent in 16 (64%), good in 7 (28%), fair in 2 (8%) patients and no poor outcome was noted. Ten minor complications were seen. CONCLUSION Fixation of paediatric forearm fractures by intramedullary Rush nail is minimally invasive procedure and outcomes are excellent to fair with acceptable complication rates.

Abstract
Background Urinary bladder carcinoma is common urological malignancy. Although epidemiological evidence favors role of occupational exposure to chemical carcinogen as the aetiological factor of bladder carcinoma, many cases arise with no obvious occupational exposure to chemical carcinogen. Tobacco and cigarette smoking is common in both rural and urban areas of Nepal.Objective The objective of this study was to determine the impact of smoking and age in urinary bladder carcinoma with related clinicopathological correlations.Method A total of 56 (44 males and 12 females) cases of urinary bladder cancer treated at Dhulikhel Hospital, Kathmandu University Teaching Hospital during time period of January 2004 to December 2013 were included in the study. Data of patients with Urinary bladder cancer were obtained from hospital records and evaluated for age, sex, history of smoking, clinical presentations, cystoscopic findings and histopathological characteristics.Results Out of 56 cases, 51 (91.1%) of the patients had hematuria. History of smoking was found in 44 patients. Smoking was found much higher in males (88%) than females (41.66%). Transitional cell carcinoma (TCC) was the most common histological variety, which was seen in 51 (91.07%) patients. The significant impact of smoking was found in terms of grade of TCC.Conclusion The incidence of bladder carcinoma is higher in male and TCC is the most common variety of Urinary bladder malignancy. History of smoking correlated with grade.Kathmandu Univ Med J 2013; 11(4): 292-295

Abstract
Aims: This study was done to know the demographic profile of women undergoing second trimester abortion at Kathmandu Model Hospital. The aim was to see the success rate of combination of mifeprostone and misoprostol for the medical induction and misoprostol alone for the cervical dilation in case of surgical evacuation.Methods: A retrospective study was done by looking at the profiles of 540 clients on whom second trimester abortion was performed during the period of October 2010 to October 2014. Twenty-nine women underwent dilatation and evacuation (D&E) with misoprostol cervical priming, and 510 underwent medical induction with mifeprostone and misoprostol whereas one client absconded. Furthermore, the reasons for seeking second trimester abortion were also investigated.Results: It can be seen that the age of women undergoing second trimester abortion at Kathmandu Model Hospital was greatest (33.33%) for the age group of 26-30 years. Most women were illiterate (31.67%) and a majority of the women were housewives (89.81%). A greater proportion of the women had never undergone abortion. Mental cause appeared to be the major reason for abortion constituting 82.04%. Success was 90.58%, expulsion with total five doses of misoprostol. The median induction to abortion time was 4-7 hours. The expulsion hours increased as the gestational age increased. The median number of dose of misoprostol required was two for medical induction and three for surgical abortion.Conclusions: Mifeprostone and misoprostol, as combination was a good method for the medical induction of second trimester pregnancy and misoprostol alone for the cervical preparation in surgical evacuation was promising.

Abstract
Aims: This study was done to find out morbidity related with puerperal pyrexia/sepsis and its risk factors. Methods: This was retrospective study conducted from January 2011 to December 2012 at Department of Obstetrics and Gynaecology, Patan Hospital, Kathmandu, Nepal. All women who delivered in this hospital within 42 days of delivery with puerperal pyrexia/sepsis diagnosed on clinical examination and relevant investigations were included in the study. Women with malaria, typhoid fever and ??other fever were excluded. The data was recorded in predesigned proforma and analyzed. Results: During this period, there were 122 cases of puerperal pyrexia. Puerperal pyrexia accounted for 6.28% of 1945 admissions. Most of the women were aged between 20-29 years, primiparous and booked cases with absent membranes. The causes of puerperal pyrexia in our study were urinary tract infection (47.5%), wound infection (20.5%), endometritis (19.7%) retained product of conception (8.2%), pyoperitoneum (2.5%) and septicemia (1.6%). Conclusions: Puerperal pyrexia/sepsis is one of the causes of preventable maternal morbidity and mortality though in our study it was not proved to be very high in number. Optimal aseptic measures during labour can prevent most of the cases.

Abstract
BACK GROUND AND OBJECTIVES Fracture of the distal radius is the most common fracture treated by the orthopedic surgeons. Although there are several treatment options available today, the aim always remains to restore the anatomy and bring back the function to near normal condition. In this prospective study we intend to evaluate the functional and radiological outcome of the unstable fracture of the distal radius when treated with external fixator. MATERIALS AND METHODS In this hospital based, Prospective study conducted in department of Orthopedics, College of Medical Sciences Teaching Hospital, Bharatpur, Chitwan, during the period from January 2011 to September 2012, 54 patients, (33 male and 21 female) with unstable fracture of the distal end of radius were included in the study. All the patients were treated with external fixator and followed for a period of 12 weeks. RESULT Among 54 patients, 52 were followed up for 12 weeks and two patients were lost to follow up after six weeks. The final result was assessed in detail on the basis of Modification, by Sarmiento et al., of the Demerit Point system of Gartland and Werley at the end of 12 weeks. The result was excellent in 25 cases, good in 19 cases and fair in eight cases. There were no poor results in this series. CONCLUSION External fixator is not only easy to use, allows re-reduction, has lower rate of complications and can be stiff enough to maintain the alignment but it is also a cost effective, patient compliant method which causes lesser morbidity to the patient as compared to the other options available.DOI: http://dx.doi.org/10.3126/jcmsn.v10i2.12950Journal of College of Medical Sciences-Nepal, 2014, Vol.10(2); 27-32

Abstract
Neurodegenerative disease is a progressive loss of neurons from central nervous system and has a huge impact on health care system. Various causes have been proposed of which inflammation has been suggested to be a probable key factor in the most of such conditions. The involvement of immune cells including lymphocytes in such diseased condition of the CNS supports this notion. The effective therapy for these diseases has been sought for more than a half century but still lacking such therapy. On such basis this review article has mainly focussed on evidence of the involvement of immune cells in various neurodegenerative diseases including Alzheimer's disease, Parkinson's diseases and Multiple sclerosis and suggests a possible therapy of such diseased conditions of the CNS by the modulation of immune system.

Abstract
BACKGROUND Molar incisor hypomineralisation is defined as the hypomineralisation of systemic origin of one to four permanent first molars, and frequently associated with affected incisors. Till date, there is no data available on molar incisor hypomineralisation in any parts of Nepal. OBJECTIVE To determine the prevalence and characteristics of Molar incisor hypomineralisation in 7 to 12 years old school children of Kavre. METHOD A total of 749 school children of age 7 to 12 years from four different randomly selected schools with at least one of the first permanent molars fully or partially erupted were evaluated using European Academy of Paediatric Dentistry criteria for molar incisor hypomineralisation. The examinations were conducted at respective schools by a single calibrated examiner. RESULT Molar incisor hypomineralisation was present in 13.7% of children. No gender differences were found.The mild type of defect (without structural loss of tooth) was the most prevalent type of molar incisor hypomineralisation with white/creamy demarcated opacities more frequent than yellow/brown demarcated opacities. Post eruptive breakdown was more in boys than in girls and this difference was statistically significant (p<0.05). Also, maxillary molars were affected more than mandibular molars and this difference was also statistically significant (p<0.05). CONCLUSION The prevalence of molar incisor hypomineralisation in Kavre was 13.7%. Demarcated opacities were more prevalent than breakdown. The hypomineralised defect was more prevalent in maxillary teeth than in mandibular teeth. The severity of defect increased with age and there was no difference in prevalence between girls and boys.

Abstract
Background Neurodegenerative disease is a progressive loss of neurons from the central nervous system (CNS). Various conditions have been implicated for such conditions including ageing, inflammation, stress and genetic predisposition. Recently, studies have linked neurodegeneration with inflammation. Some studies have suggested the harmful effect of immune response while others have argued its neuroprotective role in neurodegeneration of the CNS. However, the precise role of inflammation and immune cells in such condition is still not clear. Objective To investigate the role of lymphocytes in neurodegeneration of the CNS and determine the underlying mechanism. Method We have used 4-7 days old mouse pups (C57Bl6) to prepare organotypic slice cultures which were cultured for 13-15 days prior to experiment. To induced cell death kainic acid was used and considered as an in vitro model for neurodegeneration. Lymphocytes were obtained from peripheral lymph nodes of 5-10 weeks old adult mouse which were used in the current study. Propidium iodide was used as a fluorescent dye to determine cell death in brain slice cultures. Result Lymphocytes do not induce cell death in slice cultures in the absence of any toxic insult whereas, after applying toxic insult to the slice cultures using kainic acid, lymphocytes show neuroprotection against such insult. Similarly, purified non-activated and purified activated T cells along with T cells depleted lymphocyte preparation also exhibit neuroprotection against kainic acid-induced cell death. We further, have demonstrated that the observed neuroprotection is contact-independent and soluble mediators released from lymphocytes are responsible for the observed neuroprotection. Moreover, our study has revealed that soluble mediators exhibiting neuroprotection act via astrocytes. Conclusion Lymphocyte preparations are neuroprotective and the observed neuroprotection is contact-independent. Soluble mediators released from lymphocytes are responsible for the observed neuroprotection.

Abstract
Background Orthopedic Implant removal is one of the commonly performed elective orthopedic surgeries. Implants are generally removed after the purpose of keeping implant is solved by healing of the fracture, but there is no consensus whether routine implant removal should be a policy for all fractures that were fixed. Objective This study aims to analyze the epidemiology and outcome of implant removal surgery carried out in the past three years in Kathmandu University Hospital. Methods Patients who underwent implant removal between 2010 January to 2012 December constituted the study cohort. Demographic data, indications, types of hardware and location of fractures were recorded. Similarly, duration of surgery, type of anesthesia and duration of hospital stay were recorded. All the patients who had undergone implant removal in this three years period were called for follow up examination but those who were not able to come were interviewed on telephone. Results There were 275 implant removals constituting 7.8% of total orthopedic operations and 26.3% of fracture fixations. Male to Female ratio was 189: 86. Pediatric age group (34.5%) had the highest incidence of implant removal. Moderate sized implants were the commonest hardwares removed (63.2%). Femur (27.3%) followed by radius (26.9%) were the commonest bone for implant removal. Average operative time was 47.3 minutes with average hospital inpatient stay of 2.6 days. Commonest indication for the implant removal procedure was pain (45%). Conclusion Implant removal procedures are one of the most commonly performed elective orthopedic surgeries. Though, after orthopedic implants removal, pain relief can be expected but it is not so predictive and hence patient should be well counseled before and the indications for implant removal has to be evaluated for better patient satisfaction and safety.

Abstract
BACKGROUND Health professionals involved in a disaster are not immune to the stressors. However, little attention is given on the psychological consequences among these professionals. This study has explored the frequency of posttraumatic stress disorder (PTSD) among them after the Nepal earthquake 2015. METHODS A descriptive cross sectional study was carried out amongst the medical professionals at Manmohan Memorial Teaching Hospital, Kathmandu to assess the PTSD among them after the Nepal earthquake 2015. Two months after the post disaster the standard PTSD Checklist for DSM-5 (PCL 5) was administered to medical personnel of a hospital(n=64) along with demographic features, disaster related experience and working hours. PTSD was defined by two ways: 1.using DSM V diagnostic criteria (the presence of at least one intrusion, one avoidance, two negative alterations in cognitions/mood and two alterations in arousal and reactivity symptoms); and 2. a cutoff score of 30. RESULTS The overall prevalence of PTSD was 21.9% and 17.1% using cutoff score and diagnostic criteria respectively. Females scored significantly higher than males. No significant difference was observed according to age, marital status, profession, previous disaster experience, tragic events with relatives. Those who were present in the hospital during the initial influx of victims, witnessed patients suffering, worked extra time were at significantly high risk for development of PTSD. CONCLUSIONS This study suggest that PTSD is highly prevalent among healthcare professionals after disaster management and therefore it highlights the need for targeted interventions to specific staff who respond to large disasters to reduce the psychological burden.
