Self-prescription of Paracetamol by Undergraduate Students in BP Koirala Institution of Health Sciences.

INTRODUCTION: Self-prescription of medicines are common especially in low income countries.Paracetamol is a common medicine that is self-prescribed also among university students. Incorrect use of paracetamol can lead to ill effects on health including liver failure. There is scarce evidence of the use of paracetamol by self-medication in Nepal. The objective of this study is to evaluate the paracetamol use by self-prescription among the undergraduate students of BPKIHS. METHODS: A cross-sectional study was conducted among 570 undergraduate students of BPKIHS from February 2016 till July 2016. Pretested semi-structured, self-administered questionnaire was used to collect information regarding socio-demographic characteristics, paracetamol use and perception regarding paracetamol use. Systematic random sampling was done from a list of all medical dental and nursing students to select the study sample. RESULTS: Most (86%) students are in the category of 20-24 years. Female students are slightly more than male. Majority of the students are from Nepal. More than half of the students are from medical stream. Self-prescription of paracetamol is seen among 90.1% of the students in our study. Correct dose of paracetamol was mentioned by less than half (49.3%) of the students. Self-prescription of paracetamol is considered beneficial by all participants of this study. CONCLUSIONS: Self-prescription of paracetamol by health sciences students of B P Koirala Institute of Health Sciences is high, while the knowledge of correct dose of paracetamol for adults is low. There is a need to further explore this gap and possibly conduct further studies for other medicines as well.

Unusual mode of firearm injury from the recoiled rear end of a gun barrel.

Atypical gunshot wounds are caused by a diverse set of parameters relating to weapons and ammunition. We report a previously-unreported and atypical mode of gunshot wound produced by a detached rear end of the barrel of a gun following accidental gun fire, and discuss the difficulties in the management. A 36-year-old man presented to the emergency department with an alleged history of injury on the forehead with the rear end of a gun barrel following accidental gunfire while cleaning the nozzle. Since the time of injury, the patient was in an altered sensorium and had weakness on the right side of the body. There was minimal but continuous bleeding from the wound, with extrusion of brain matter. Skull radiograph showed that the rear end of the barrel had entered the left frontal bone, with associated depressed fracture of the frontal bone. The patient underwent a bicoronal, bifrontal craniotomy with a T-shaped extension towards the barrel to facilitate the reflection of the scalp flap and to avoid any movement of the barrel as it might further injure the brain. Necrotic brain, dura and bone pieces were removed. The patient was doing well at follow-up except for mild residual motor deficits. This case illustrates that while working with limited facilities, particularly in underdeveloped countries, a careful clinical assessment, interpretation of available images and a judicious operative approach can help to save the patient.

Epidemiology and management of paediatric head injury in eastern Nepal.

BACKGROUND: In children, majority of the head injuries are minor and management of critically ill children depend on a team approach using well-rehearsed, systematic management protocols that can be implemented within hours after injury. This study was carried out to ascertain the epidemiology and management of know the demographic profile and etiology of paediatric head injury in our setting, to know the clinical and radiological characteristics of head injury patients and to know the treatment options and outcome in paediatric head injuries. PATIENTS AND METHODS: Details of all children (age <16 years) with head injury seen in 1 year from 01.04.2005 to 31.03.2006 were retrospectively reviewed. Demographic profile, clinical details, investigations, treatment offered, and outcome were noted in a proforma. All data were analyzed by appropriate SPSS 11.0 statistical software tools. RESULTS: There were total 43 patients. Young male children were more commonly affected in present series with a mean age of 7.67 years (median - 5.010 years), range 6 months-16 year. Fall (65.11%) was the most common mode of injury followed by road traffic accidents (RTAs) (25.6%). Mild head injuries (65.11%) were most common. Most common complaint was loss of consciousness and all the patients with severe head injury presented loss of consciousness. All patients with mild head showed good recovery; with moderate head injury, nine patients showed good recovery and three patients recovered with moderate disability. Patients with severe head injury (three patients) had 100% mortality. CONCLUSIONS: In urban areas of Nepal, RTAs like vehicular crashes, motor cycle accidents, and pedestrian hit by moving vehicle are more common and in rural areas fall from height are commoner. We need to develop child safety legislations and risk-specific intervention programs in Nepal.

Complete elimination of tetanus is still elusive in developing countries: a review of adult tetanus cases from referral hospital in Eastern Nepal.

AIM: To analyse demography, clinical presentation, treatment, complications and outcome of patients with tetanus over a 2-year period. MATERIALS AND METHODS: A retrospective analysis of medical records of all patients with tetanus admitted to the intensive care unit of B.P Koirala Institute of Health Sciences, Dharan, Nepal between July 2004 and June 2006. RESULTS: Tetanus accounted for 1.1 % of our ICU admission. Eight tetanus patients (mean age 52 years; M: F ratio 7:1) were admitted. The tetanus prone wounds of seven patients were managed at home. The most common presenting complaints were trismus and stiffness of neck and back (87.5%). Elective intubation was followed by tracheostomy in all the patients. Overall mean duration of ventilatory support was 12.5 days. Treatments given in ICU were diazepam, magnesium sulphate, tetanus immunoglobulin, metronidazole, wound management and supportive measures. Five patients (62.5%) developed autonomic instability and three patients had ventilatory associated pneumonia (37.5%). Average ICU stay was 15.1 days while hospital stay was 20.1 days. Five patients (62.5%) survived the course of disease. Two patients (25%) left the hospital against medical advice while the other (12.5%) died in ICU. CONCLUSION: Tetanus is a vaccine preventable disease. Tetanus prone wounds should be managed appropriately. Respiratory compromise and autonomic instability are the main causes of morbidity and mortality. Early recognition, intense support and prompt treatment improves morbidity and mortality of patients diagnosed with tetanus.

Mitigating nitrous oxide and methane emissions from soil in rice-wheat system of the Indo-Gangetic plain with nitrification and urease inhibitors.

Mitigation of methane (CH4) and nitrous oxide (N2O) emissions from soil is important to reduce the global warming. Efficacy of five nitrification inhibitors, i.e. neem (Azadirachta melia) cake, thiosulphate, coated calcium carbide, neem oil coated urea and dicyandiamide (DCD) and one urease inhibitor, hydroquinone, in mitigating N2O and CH4 emissions from fertilized soil was tested in rice-wheat system in the Indo-Gangetic plains. The closed chamber technique was used for the collection of gas samples, which were analyzed using gas chromatography. Reduction in N2O emission on the application of nitrification/urease inhibitors along with urea ranged from 5% with hydroquinone to 31% with thiosulphate in rice and 7% with hydroquinone to 29% with DCD in wheat crop. The inhibitors also influenced the emission of CH4. While application of neem coated urea, coated calcium carbide, neem oil and DCD reduced the emission of CH4; hydroquinone and thiosulphate increased the emission when compared to urea alone. However, the global warming potential was lower with the inhibitors (except hydroquinone) as compared to urea alone, suggesting that these substances could be used for mitigating greenhouse gas emission from the rice-wheat systems.
