Publication An overview of over the counter drugs in pregnancy and lactation(Kathmandu University, 2006) BP, Das; M, Joshi; CR, PantOver the counter (OTC) drugs are commonly used by pregnant women. Most OTC drugs are safe in pregnancy but some have unproven safety and may adversely affect the growing foetus. The safety profile of some of the medication may change according to the gestational age of the foetus. Because an estimated 10% or more of the birth defects results from maternal drug exposure, the US Food and Drug Administration (FDA) has assigned a risk category to each drugs. Among the commonly used OTC drugs Acetaminophen, Chlorpheniramine, Kaolin and Pectin preparations and most antacids have a good safety record. The drugs like H2 blockers; Pseudoephedrine and Atropine/ Diphenoxylate should be used with caution. The risk and benefit while using OTC drugs in pregnancy has to be assessed.

Materials & Methods A total of 191 prescriptions were randomly audited at varying time interval from the department of ENT in the year2003. The data was collected in customized Performa in the form of antibacterial audit questionnaires. It also contained Patient particulars, diagnosis, investigations, drug details and information from the prescriber regarding the indication for prescribing antimicrobial agent, suspecting organism underlying infection, duration of therapy and details of any concomitant medications. Results The incidence of use of antimicrobial agents (AMA) in 191 prescriptions was analyzed from the enrolled prescriptions, a total of 218 antimicrobials i.e.1.4 antimicrobial agent per patient were prescribed. .The AMAs were indicated therapeutically in 73.29% of patients & 19.37% patients for prophylaxis. The AMAs were advised for more than 72 hours for prophylaxis in 86.48%. In the concomitant medications antihistaminic were prescribed in 32.62% and NSAIDS in 21.98% cases. Most of patients reported with upper respiratory tract infections (URTI- 32.56%), Chronic Suppurative otitis Media (CSOM-18.3%), sinusitis (6.28%), tonsillitis (5.75%),. Pharyngitis (3.66%), Acute Suppurative Otitis Media (ASOM-2.61%) and others. The diagnosis was established clinically in 42.40% and confirmative in 35.60%. In 21.46% the diagnosis was not disclosed. Out of 191 patients, culture sensitivity tests were performed for only 31 patients and 13 patients depicted a positive culture sensitivity tests. The common microbes isolated from the culture were staphylococcus aureus (69.2%). Streptococcus (7.7%), Enterobacteriacae (7.7%), Pseudomonas auroginosa (7.7%) & psendomanas mirabilis (7.7%). Clinically suspected organism were mentioned in only 32 prescriptions and most prescriber presumed the infections due to staphylococci & pseudomonas (43.75%), streptococci (21.8%),Gram negative organisms (12.5%) and H influenza (9.3%).The use of a single drug was abundant (89.52%), two drugs (9.94%), and three drugs (0.52% )prescriptions. Ciprofloxacin (23.85%) was preferred, followed by amoxycillin (20.06%), combination of ampicillin + cloxacillin( 9.17%), doxycyclin (5.96%). Erythromycin (4.58%) and cotimoxazole (4.58%). Expensive drugs i.e azithromycin (2.75%), roxithromycin (1.37%) and cephalosporins (3.21%) were also prescribed. The causative microbes were sensitive to amoxycillin (53.84%), cloxacillin (53.84%) ciprofloxacin (46.15%), gentamicin (46.15%), and cephalosporin (46.15%). But resistant to erythromycin, tetracycline, cotrimoxazole and norfloxacin) Conclusions-Majority of patients were prescribed drugs irrationally with misleading indications without confirming the bacteriological culture and sensitivity.

The genetic predisposition plays a key role in the genesis of epilepsy. The already existing antiepileptic drugs (AEDs) provide effective control of majority of patents with different types of seizures. In some refractory cases and in those patients who can not tolerate the conventional AEDs, there is an urgent need to provide relief by controlling the seizures adequately. Various newer approaches in the rational management of seizures have been evolved during the recent years, based on different mechanisms of action and side effects profile. A brief account of these newer treatment modalities have been incorporated in this review in order to enlighten the readers about the possible beneficial effect of this regimen vis a vis the limitations of such use. Keywords: Neurotransmitter imbalance, defective gene, newer antiepileptic drugs, plasma levels, newer approaches.Publication Recent trends and directions in the rationalization of pharmacotherapy of bronchial asthma: Probing for alternatives(Kathmandu University, 2006) BP, Das; A, SethiAlthough tremendous progress has been made in the understanding of Bronchial Asthma (BA) over the past decade, asthma remains a frequently encountered challenging condition for the physicians in the health care locale. Inflammation is distinguished as the most important event in the pathogenesis and the knowledge that asthma is an inflammatory disorder has become elementary to our explanation of asthma; this has broadened the perspective for the treatment of BA. However, bronchodilators and corticosteroids are still the mainstay of asthma treatment over the decades. The introduction of superior derivatives of corticosteroids and beta agonists, the choice, safety, duration of action and ease of delivery have enhanced progressively. Surrogated anti - inflammatory agents have been used in severe disease, but have been limited by adverse effects. The introduction of new agents affecting leukotrienes synthesis and action provides an alternative strategy but it needs to be confirmed on a large subset of population of asthmatics. In fact, the past decade has been witnessed by a proliferation of scientific information and a widespread addition of anti-inflammatory therapy to improve asthma outcomes along with the recommended therapies. In this context, there has been much advancement in the available pharmacologic panorama for both chronic and acute therapy and the development and approval of novel medications. Yet, many controversies abound this disorder, and further fundamental developments in novel therapeutics are imminent. This review of asthma for the practicing clinician will summarize these developments and their implications in treatment of BA Key words: Bronchial Asthma (BA), Pharmacotherapy, Review, Novel DrugsPublication Social health insurance: A knowledge-do gap in eastern Nepal(Kathmandu University, 2007) N, Jha; P, Karki; BP, Das; N, ChapagainHealth care costs, and those for inpatient care in particular, pose a barrier to seeking health care, and cost be a major cause of indebtedness and impoverishment, particularly among the poor. The Ministry of Health in Nepal intends to initiate alternative financing schemes such as community and social health insurance schemes as a means to supplement the government health sector financing source. Social Health Insurance (SHI) is a mechanism for financing and purchasing / delivering health care to workers in the formal sector regulated by the government. Considering all these facts BP Koirala Institute of Health Sciences (BPKIHS) has introduced SHI scheme in 2000 as an alternative health care financing mechanism to the community people of Sunsari and Morang districts. In the beginning small area was elected as a pilot project to launch the scheme. A major objective of SHI is to reduce poverty caused by paying for health care and to prevent already vulnerable families from falling into deeper poverty when facing health problems. A total of 26 organizations with 19799 populations are at present in SHI scheme. Sixteen rural based organizations with 14,047 populations and 10 urban based organizations with 5752 people are the beneficiaries in this scheme. BPKIHS SHI Scheme is the outcome of the visionary thinking on social solidarity and as an alternative health care financing mechanism to the community. BPKIHS is mobilizing people's organizations and is offering health services through its health insurance scheme at subsidized expenses. This has helped people to avail with health facilities who otherwise would have been left vulnerable because of their penetrating health needs. There is huge gap between premium collection and expenditures. The expenditures are more and this may be due to knowledge – do gap in the program. If conditions are unsuitable, SHI can lead to higher costs of care, inefficient allocation of health care resources, inequitable provision and dissatisfied patients. It can also be more difficult to realize the potential advantages of SHI in future. The future challenges confronting the scheme are to give the continuity and sustainability of the program to its catchments areas. This might entail a shift in its program operation mechanism. People's active involvement is required, which will further provide a sense of ownership in the scheme amongst the people.Publication Vagus nerve stimulation: A novel approach for prevention and control of refractory seizures(Kathmandu University, 2007) SK, Bhattacharya; BP, Das; GP, Rauniar; H, SangraulaIn order to understand the brain function and to treat various neuropsychiatric illnesses including epilepsy, continued search and discovery of newer antiepileptic drugs has failed to revolutionize the approach in the management of this complex disorder. Moreover, in close to 30% of epilepsy patients, the seizure control is either not satisfactory or it is intractable to pharmacotherapy. Amongst the non-pharmacological treatment options for refractory epilepsy, vagus nerve stimulation occupies a unique position as an adjunctive treatment in prevention and control of partial-onset seizures in adults and adolescents older than 12 years. Though the precise mode of action of VNS is still debatable an honest attempt has been mode here to review all possible literatures available on VNS to establish its role in the management of this complex disorder.
