Bilateral Total Hip Replacement In Steriod Induced Avn In A Young Patient.

A 30 years old female patient presented us with pain, restricted movement of hip and difficulty of walking. She had past history of taking oral Steroid for 6 months for gaining weight. Radiological examination revealed bilateral avascular necrosis of hips with advanced osteoarthritic changes. The patient had sequential Total hip replacement on both sides in 6 weeks interval. Post operatively she was uneventful and after proper exercise and physiotherapy she is maintaining her daily household activities smoothly.

Prescription writing skills of pre-clinical medical and dental undergraduate students.

Objective of this prospective study was to assess the acquisition of prescribing skill of preclinical medical and dental undergraduate students. Prescription writing skills of 258 students of both first and second year of MBBS and BDS students were analyzed through an objective structured practical examination. MBBS student of second year scored 85.01% and 92.82% respectively in physician and drug related component whereas first year MBBS students scored 89.9% and 83.4%. BDS student of first year scored 91.96% and 86.33% in physician and drug related components which is better than second year that scored 83.33% and 77.94% respectively. This study revealed that the students of both courses acquire prescribing skills to a limited extent during preclinical phase. Prescribing errors were found both in physician and drug related components. To minimize the different form of prescribing errors vigorous training in the internship period will help to minimize prescribing errors and improve rational prescribing too.

Prevalence of antimicrobial chemotherapy in hospitalized patients in the department of internal medicine in a tertiary care center.

Use of antimicrobial agents (AMAs) is associated with significant reduction in morbidity and mortality. However, indiscriminate and injudicious use of AMAs leads to the ineffective treatment, increased adverse effects, exacerbation or prolongation of illness, emergence of bacterial resistance and an additional burden of an expensive medical cost to the patients. So controlled use of AMAs at right dose, right interval and right duration is of utmost importance. In this retrospective study, prevalence and prescription patterns, and cost of the prescribed AMAs in the hospitalized patients in the department of internal medicine in a tertiary care center were analyzed. A total of 428 hospitalized patients were included in the study. Out of 428 patients, 274 (64.0%, P < 0.01) patients received AMAs for therapeutic (66.4%) and prophylactic (24.1%) purposes. In 9.5% patients AMA prescription was inappropriate. Use of intravenous route was significantly higher (55.48, P < 0.01) than the oral route. COPD with acute exacerbation was most frequent condition for AMA prescription. Majority (90.42%) of AMA prescriptions were based on empirical basis. Mean number of AMA per patient was 2.12 (minimum 1 and maximum 8). Most frequently prescribed AMA was Ceftriaxone (30.2%) from cephalosporin group (33.9%, P < 0.05). Patients received AMAs for the duration of 1-31 days and total cost of single AMA dosage regimen was as high as $ 482.3. As most of the hospitalized patients were prescribed AMA empirically, strategic AMA prescription guidelines and AMA prescription monitoring systems are extremely necessary in the hospitals to prevent emergence of microbial resistance and to expedite the cost effectiveness of medical treatment.

Recent advancement in drug delivery system.

Ease of drug administration, safety, affordability and efficacy are the major concerns in pharmacotherapy leading to exploration of better drug delivery systems. Liposomes are lyotropic liquid crystals composed mainly of amphiphilic bilayers and these are more frequently used as drug carriers. Liposomes help reduce the toxicity and deliver the drug to the target tissue. So far, liposomes have been the most intensively studied lipid-based delivery system. In liposomes, a hydrophilic drug can be trapped in aqueous interior or channels between successive phospholipids bilayers whereas a hydrophobic drug can reside with the bilayer itself. The non-toxic and nonimmunogenic bilayers dissipate allowing the diffusion of the drug into the tissues. Attachment of polyethyl glycol to the surface of liposome (known as stealth liposome) aids in the better targeting of the drug to the tissues. Pegylated proteins and polymers of lactic and glycolic acids have been well studied as drug carriers and found to be resistant to phagocytosis and complement activation. Newer DNA based strategies including DNA vaccination and antisense oligonucleotides and immunomodulation show good results for new therapeutic systems. Though the DNA based therapeutic systems have high selectivity and specificity with few adverse effects, these systems are so far restricted to animal models and clinical trials.

Teaching exercise of drug utilization by medical students.

The prescription is a vital written document communicating between the physician, the patient and the pharmacist. The audit of prescribing pattern is a component of medical audit, which seeks monitoring, evaluation and necessary modifications in the prescribing practices of prescribers to achieve rational and cost effective medical care for the patients, The present drug utilization study was conducted by fourth year MBBs students during their research posting in the department of Pharmacology at B.P. Koirala Institute of Health Sciences (BPKIHS), Dharan. The prescriptions were randomly collected from BPKIHS pharmacy over a period of 3 weeks. The auditing was done in the form of a semi structured performa containing the patients particulars with regard to age, sex, and residence, the details of the illness and prescribed drug information. The data was analyzed at the end of the study. The study points out that the maximum (27.5%) prescriptions were from General Outpatient Department (GOPD) followed by ENT (16.5%), Internal medicine (15.5%) and General surgery (10%). This indicates the distribution of patient load in hospital and the dominant areas to be targeted for intervention. Further, the proportion of antimicrobial agents (AMAs) i.e. 26.03% use was low and was prescribed empirically in most of the cases. There was use of expensive AMAs and irrational prescribing of combinations of AMAs in some prescriptions. Other prevailing drugs which were prescribed were analgesics. The usage of nimesulide and rofecoxib. withdrawn by FDA were used recurrently in this setup. There was greater use of dubious drugs of unproven benefit like vitamins, calcium etc. The diagnosis of the disease were not mentioned in 32.5% of prescriptions, The dose, frequency and duration of drugs were unascertained in majority of prescriptions that might lead to health hazards. This exercise might change the behavior of existing prescribers and also of the future doctors.

Medical errors challenges for the health professionals: need of Pharmacovigilance to prevent.

The incidence of different aspects of iatrogenic problems due to drugs is Adverse Events (AEs) 3.7%, Adverse Drug Events (ADEs) 2.4-6.5%, Adverse Drug Reactions (ADRs) is 6.7%. Negligence in serious ADEs and death is 34% and 51% respectively, preventable ADEs is 25-50%. Medication Errors (MEs) occur most often in perscribing (29-56%). The most common cause of MEs is lack of knowledge about the drug (29%) and the patient about 18%. MEs result malpractice claims in 13-25% of cases which occur due to mistakes and slips of action & lapses of memory. The MEs can be prevented by establishing effective Pharmacovigilance control center, which frequently gives proper guidance to the prescribers. Use of computerized decision for prescription writing, effective communication with patient, families, pharmacists and nurses and continuing medical education on information of new drugs and new information on current drugs can be effective tolls to prevent the errors.

Relationship between plasma leptin and plasma insulin levels in type-2 diabetic patients before and after treatment with glibenclamide and glimepiride.

Type 2 diabetes affects 100 million people throughout the world. Among the various factors implicated in the causation of this disease, the role of leptin, an obesity gene product, is increasingly being investigated. This especially assumes importance in the light of knowledge that obesity confers a minimum of 3-10 fold higher risk of diabetes. This study was planned to investigate the relationship between leptin and insulin levels in type 2 diabetic patients before and after treatment with glibenclamide or glimepiride. 60 type 2 diabetic patients were recruited for the study and were divided into 2 groups-one receiving glimepiride and the other group receiving glibenclamide for duration of 10 weeks. This study demonstrated a highly positive correlation of plasma leptin levels with BMI, plasma insulin and insulin resistance. No gender specific differences were observed in leptin concentrations. The study, however, failed to demonstrate any possible relationship between glycemic control as assessed by blood sugars/ glycosylated hemoglobin (HbAlc) and plasma leptin. The administration of glibenclamide or glimepiride significantly lowered blood glucose levels coupled with a decrease in (HbAlc). Both the drugs increased insulin concentrations. Glibenclamide increased leptin levels but they remained unaltered with glimepiride. Glibenclamide and glimepiride were found to be equally effective in their glucose lowering action. However, the patients receiving glibenclamide experienced higher episode of hypoglycaemic spells than those receiving glimepiride.

Vagus nerve stimulation: a novel approach for prevention and control of refractory seizures.

In 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.

Social health insurance: a knowledge-do gap in eastern Nepal.

Health 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.

An overview of over the counter drugs in pregnancy and lactation.

Over 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.

Recent trends and directions in the rationalization of pharmacotherapy of bronchial asthma: probing for alternatives.

Although 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.

Knowledge, attitudes and practices (KAP) regarding the management of diarrhea by pharmacists and licensed drug sellers in eastern Nepal.

Diarrhea constitutes a major cause of morbidity and mortality in developing countries. Inappropriate drug prescribing is common in diarrhea, resulting in an increase in cost and adverse drug reactions. In Nepal, drug sellers often act as the first contact persons for the underprivileged. No information has been available regarding their knowledge, attitudes and practices (KAP) regarding diarrhea management. Using a structured questionnaire, between the 1st of January and the 31st of December 2003, 109 drug sellers in eastern Nepal were interviewed about their educational status, patient/attendant presentation at the outlet and their advice to patients/attendants. Only 2.7% of drug sellers were qualified in health education. Eighty percent of the patients/attendants sought advice from the drug sellers, only 20% presented to the outlet with prescriptions. The data reveals that about half of them were taking note of the nature of the diarrhea. Although 62 (56.8%) of them were aware of dehydration, only 2 (1.8%) of them knew all three signs of dehydration (dry tongue, non-elastic skin and sunken eyes). Sixty-six (60.5%) of them knew about oral rehydration solution (ORS), its principle and the required period of administration. About 50 to 60% of them were aware of the implications resulting from dehydration from uncontrolled diarrhea and of the importance of ORS in its management. Only 20% of the drug sellers advised ORS alone, otherwise it was dispensed along with drugs, such as antimotility agents (AMA) or metronidazole. As a result of the above findings, it is important to educate the drug sellers by conferring knowledge about the ethical aspects of drugs in the management of diarrhea.

Pattern of intraocular pressure changes following manual small incision cataract surgery.

OBJECTIVES: To find out the pattern of changes in intraocular pressure after manual small incision cataract surgery. METHODS: Consecutive patients (291 eyes of 291 patients) undergoing manual small incision cataract surgery were prospectively evaluated for change in IOP. Patients were further divided into two groups based on whether or not sutures were used to close the scleral tunnel. IOP was serially measured at day 1, 1st, 2nd, 4th, 6th, 8th and 12th week. RESULTS: The mean post operative IOP in eyes where sutures were not applied (12.59+/- 3.02 mmHg, 12.59+/-2.34mmHg, 12.54+/-2.19mmHg and 12.40+/-2.99 mm Hg at day1, 2week and 4weeks respectively) was lower than that where sutures were used to close the wound (15.57+/- 3.86mmHg, 14.05+/-2.52mmHg, 14.43+/-3.39mmHg at day1, 2weeks and 4 weeks respectively). There was a drop of IOP from the preoperative IOP in both suture (1.15+/-3.29mm Hg) and non suture (3.29+/-3.07mm Hg) group at 3 months of follow up. CONCLUSION: There is a small drop of IOP following sutureless MSICS during long term follow up. Eyes where sutures are applied are more likely to have higher IOP than those without sutures at the initial post operative period.

Recent advances in the management of epilepsy: a review.

Epilepsy is a complex disorder affecting brain function having a variety of contributing factors. 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.

Antimicrobial utilization pattern in out patient services of ENT department of tertiary care hospital of Eastern Nepal.

OBJECTIVE: The objective of this study was to monitor the antimicrobial utilization in ENT out patient services in a tertiary care hospital of Nepal. MATERIALS & METHODS: A total of 191 prescriptions were randomly audited at varying time interval from the department of ENT in the year 2003. 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.

Entomological indices of Aedes aegypti at some international airports and seaports of southern India--a report.

Entomological surveys were undertaken at some of the international airports/seaports (Bangalore, Calicut, Chennai, Cochin, Thiruvanathapuram and Vishakapatnam) to find out the breeding prevalence of dengue vector mosquito in diverse breeding containers from 1998 to 2004. Three vector indices (House index, Container index and Breateu index) were used to assess the breeding potential at each airport/seaport. International Health Regulations urged national governments to keep all the international airports/seaports and peripheral areas up to 400 meters free from Aedes aegypti mosquitoes. However, surveys revealed high vector indices at all the airports and seaports. Health authorities of airports/seaports need to take cognizance of these facts and develop action plan for appropriate control measures with emphasis on vector surveillance.

First time detection of Japanese encephalitis virus antigen in dry and unpreserved mosquito Culex tritaeniorhynchus Giles, 1901, from Karnal district of Haryana state of India.

Japanese encephalitis virus (JEV) antigen has been detected by antigen capture enzyme linked immunosorbentassay (ELISA) in dry specimens of the mosquito Culex tritaeniorhynchus Giles, 1901, collected from Karnal district of Haryana state in northern India. These mosquitoes were stored in dry condition for 20 months, at room temperature, before processing. The procedure of detecting JEV infection in long time stored, dry vector mosquitoes, has important application in the surveillance of Japanese encephalitis.

Cytological diagnosis of rhinosporidiosis with skeletal involvement--a case report.

A young Hindu male presented with painful swelling of left lower thigh for 6 months.The provisional diagnosis both clinically and radiologically was osteosarcoma. FNAC and biopsy proved the lesion to be a case of rhinosporidiosis. The present case is reported due to rare incidence of skeletal rhinosporidiosis.

Effect of nimodipine, a dihydropyridine calcium channel antagonist on the pharmacokinetics of carbamazepine in rhesus monkeys.

Calcium channel antagonists have been shown to have an anticonvulsant activity in a variety of seizure models and also to potentiate the anticonvulsant activity of other standard antiepileptic drugs like carbamazepine, phenytoin and valporoate. A pharmacokinetic interaction may be involved in such potentiation. This cross over single dose study was carried out to find out if there was a pharmacokinetic interaction between carbamazepine, a commonly used antiepileptic drug and nimodipine, a dihydropyridine calcium channel antagonist in rhesus moneys. Carbamazepine 46 mg/kg and nimodipine 9.6 mg/kg was administered through a nasogastric tube and blood samples were collected at 0.5, 1, 2, 3, 6, 9, 12, 24, 48, 72 and 96 hours after drug administration and were assayed for carbamazepine. Nimodipine caused a significant increase in peak plasma concentration (C(max)) of carbamazepine and a decrease in plasma absorption half life (t1/2 alpha). There was no significant change in other pharmacokinetic parameters between the two groups. The results of the study suggest that concurrent administration of carbamazepine and nimodipine may cause a significant rise in carbamazepine concentration as may contribute to a potentiation of anticonvulsant effect of carbamazepine and an increase in the incidence of adverse effects warranting that nimodipine should be prescribed cautiously in epileptic patients receiving carbamazepine and it might be very appropriate to do therapeutic drug monitoring of carbamazepine in such patients.
