Phenobarbitone induced drug reaction with eosinophilia and systemic symptoms (DRESS): a case report

Drug reaction with eosinophilia and systemic symptoms (DRESS) is a life threatening cutaneous drug reaction with visceral involvement and hematological abnormalities. Being a rare side effect, it is often under-reported and misdiagnosed. The fatal adverse drug reaction is associated most commonly with aromatic anti-epileptics phenytoin, carbamazepine and less frequently with phenobarbitone. Here, we report a case of phenobarbitone induced DRESS in a 1 year old male child. He succumbed to fulminant hepatic failure inspite of being put on steroids, hepatoprotectives, antibiotics and ventilatory support

To study the rate of HIV Sero-positivity in paediatric patients with high risk clinical profile

Background: Understanding the magnitude and clinical profile of pediatric HIV is essential for the clinicians and policy makers. The study was aimed to determine the rate of HIV seropositivity in pediatric patients with high risk clinical profile, study the clinical presentations and the mode of transmission of HIV in children.Methods: This prospective hospital-based study to screen 244 children aged 18 months to 12 years with high risk clinical profile for HIV seropositivity was carried out for a period of 1 year.Results: Of the 244 children screened, the commonest clinical features associated with high risk profile were failure to thrive in 200 (81.97%), persistent fever in 151 (61.89%), chronic diarrhoea in 76 (31.15%), cough >1month 112 (45.90%) patients. HIV seropositivity was reported in 11/244 (4.51%) patients; with failure to thrive in 10/11 (90.90%), chronic diarrhoea in 09/11 (81.81%), seborrheic dermatitis in 2/11 (18.18%) patients followed by persistent cough, severe malnutrition, oral thrush, generalized lymphadenopathy and recurrent bacterial skin infections in 1 patient each out of 11(9.09%). Chronic diarrhoea was a significant independent clinical risk factor for predicting HIV seropositivity (Chi2 = 13.81, p<0.001, Odds ratio=11.15). The probability of HIV seropositivity increased significantly with the number of risk factors concomitantly present, with 30% seropositivity in those with four clinical risk factors (Chi2 =32.89, D. F=1, P<0.001). The parents of all seropositive children were seropositive.Conclusions: The probability of HIV infection in a child depends upon the nature and number of clinical manifestations present. All HIV positive children h HIV positive parents in this study indicating vertical transmission

Bedaquiline: a new weapon against MDR and XDR-TB

Multidrug-resistant tuberculosis (MDR-TB) is a global public health problem. It requires treatment with combination therapy consisting of four to six drugs including combinations of bactericidal and bacteriostatic drugs, usually for a period of 2 years. There is alarming rise in MDR and XDR-TB all over the world and better treatment options are needed to control the global MDR-TB and XDR-TB epidemic. Drugs which can shorten the treatment duration and which are free from serious adverse effects are urgently needed. Bedaquiline (TMC-207) is a newly FDA approved anti-TB drug, having unique mechanism of action i.e. causes inhibition of the proton pump activity of the ATP synthase in M. tuberculosis and targets the energy metabolism. It is found to active within macrophages, and is a promising agent in shortening the duration of anti- TB treatment. It is metabolized by CYP3A4, so interactions with inducers and inhibitors of this enzyme are expected. It has shown promising results in preclinical and clinical studies and it seems to be a good option for MDR and XDR-TB. Adverse effects reported in various studies were of mild nature except nausea which was the most commonly associated. Few cases of prolongation of QT intervals were reported, so it demands careful monitoring and use of bedaquiline as a reserve drug for patients in whom conventional regimens are not effective. Currently it is approved as part of combination therapy in adults of ≥18 year with pulmonary MDR-TB. Long term studies are needed to explore its full safety profile

Risk of cardiac pacemaker pocket infection in a tertiary care hospital

Background: The risk of pacemaker pocket infections (PPIs) is rare with good antisepsis techniques and use of advanced antibiotics. However, injudicious antibiotic usage leads to the rise of multidrug-resistant bacteria, which may cause PPI. Few reports exist about the microbial spectrum of the PPI from our country, prompting us to study the same. Methods: We conducted this retrospective observational study for 3 years (January 2013–February 2016) from all the patients with PPI. We collected the relevant clinical samples (blood and pus) for the microbial culture using a standard protocol. We included 100 samples collected from the medical staff and the hospital environment as a control sample. The data were analyzed using appropriate statistical methods and a P< 0.05 was considered statistically significant. Results: Our data showed that 17 out of 160 (10.6%) patients had PPI. Coagulase negative Staphylococcus sp. was isolated in 7 (41.2%) patients, followed by Staphylococcus aureus in 4 patients (23.5%). Other isolated bacteria include multidrug-resistant Burkholderia cepacia (n = 3), Mycobacterium abscessus (n = 2) and polymicrobial infection in a single patient. One out of hundred surveillance samples grew B. cepacia. Conclusion: Our data revealed a high incidence of Gram-positive cocci causing PPI. Every hospital should formulate their antibiotic policy based on the pattern of the hospital flora and their drug sensitivity

A pharmacoeconomic analysis to determine the relative cost-effectiveness of bimatoprost 0.03% eye drops and brimonidine 0.2% eye drops in patients of primary open-angle glaucoma/ocular hypertension

Aims: The aim was to compare efficacy and cost-effectiveness of bimatoprost 0.03% and brimonidine 0.2% in primary open-angle glaucoma (POAG)/ocular hypertension (OHT). Settings and Design: Open, randomized, cross-over, comparative study. Materials and Methods: Forty patients of POAG or OHT with intraocular pressure (IOP) <30 mm Hg were included in the study after a written informed consent. The patients were divided randomly into two groups of 20 patients each. Patients of group A were administered bimatoprost 0.03% eye drops once daily, and those of group B brimonidine 0.2% eye drops twice daily for a period of 4 weeks. After a washout period of 4 weeks, the patients were crossed over that is, group A was administered brimonidine 0.2% and group B bimatoprost 0.03%. Fall in IOP at 4 weeks was recorded. The daily cost of each drug was calculated by maximum retail price and the average number of drops per bottle. The cost-effectiveness was then calculated as the cost of drug/mm Hg fall in IOP. Statistics: Independent samples t-test was used to compare the efficacy of both drugs. Results: IOP lowering with bimatoprost (8.9 ± 1.598 mm Hg) was significantly (P < 0.0001) higher than brimonidine (6.55 ± 1.26 mm Hg). The number of drops/ml were 33.43 ± 0.52 and 25.49 ± 0.26, respectively, for bimatoprost and brimonidine. Treatment with bimatoprost was costlier than brimonidine with daily costs/eye Rs. 4.02 ± 0.06 and 3.14 ± 0.03, yearly costs/eye Rs. 1467.46 ± 20.74 and 1147.75 ± 11.15, respectively. Bimatoprost was more cost-effective than brimonidine with the cost-effectiveness ratio (CER) respectively Rs. 13.10 ± 2.61/mm Hg and Rs. 13.96 ± 2.86/mm Hg. Incremental CER Rs. 10.43/mm Hg implies lower costs/mm Hg extra IOP lowering by bimatoprost than Rs. 13.96 for brimonidine. Conclusion: In spite of being costlier, bimatoprost is more efficacious and cost-effective than brimonidine

The prevalence of malocclusion and orthodontic treatment needs in school going children of Nalagarh, Himachal Pradesh, India

Objective: The aim of this study was to determine the prevalence of malocclusion and orthodontic treatment need in 13–18-year-old schoolchildren of Nalagarh, Himachal Pradesh, India using the Index of Orthodontic Treatment need (IOTN) and to analyze the treatment needs between males and females and correlation between the esthetic component (AC) and dental health component (DHC) of IOTN. Subjects and Methods: The sample comprised 2000 school children (1125 females and 875 males) who had not undergone orthodontic treatment. No radiographs, study casts, were used; IOTN was calculated from clinical examination. Results: DHC results showed that little need for orthodontic treatment was found in 31.6% and moderate need in 30.85%. A great need was estimated at 37.55%. Severe contact point displacement of more than 4 mm was the most common occlusal feature in the definite treatment need group, followed by increased overjet, impeded eruption of teeth, and anterior or posterior cross bite. AC results showed that little need for orthodontic treatment was in 86.15%, moderate need in 8.90%, and great need in 4.95%. Limitations: Index does not consider midline discrepancy, soft tissue abnormalities, and AC does not include Class III and Class II div 2 malocclusion photographs. Conclusions: There seems a discrepancy in the proportion of children needing orthodontic treatment on esthetic and dental health grounds. This study provides baseline data on the need and demand for orthodontic treatment among the sample which is important for planning public orthodontic and dental services
