Abstract
Background: Unsafe injection practices are common in developing nations. Such practices, through contaminated needles and syringes, place injection recipient, healthcare workers and the community at large at risk of infection with blood borne viruses. Aim: An attempt was made to briefly describe an acute hepatitis outbreak that occurred in Gujarat, India, due to unsafe injection practices with a brief review of the literature. Subjects and Methods: An outbreak of acute hepatitis occurred in February-March 2009 in the Sabarkantha district of Gujarat in India. Blood samples were collected randomly from 25 cases, admitted in the local hospital during the ongoing outbreak. Screening was done using an immunoassay analyzer (Cobas e411; Roche Diagnostics, Indianapolis, IN, USA) for hepatitis B surface antigen (HBsAg), IgM and total antibodies to hepatitis B core antigen (HBc), hepatitis B e antigen (HBeAg) and antibody to HBe, antibodies to HCV, HIV and IgM antibodies to hepatitis A virus (HAV), as per the manufacturer's protocol. Results: Gross and continuous use of contaminated needle and syringes were responsible for this outbreak as all the patients gave history of receiving injections about 2-3 months prior to the development of clinical signs and symptoms, from one particular doctor. Mean age of the patients was 33.4 years (SD 12.9 years). Seventeen of these patients were males and eight were females. All patients were hepatitis B surface antigen positive, with median levels as 35,450 IU/mL (IQR 450-2,49,750 IU/mL). IgM HBc was positive in 22/25 (88%). HBe Ag was positive in 11 patients (44%). The median HBV DNA level was 2.6 × 104 IU/mL (IQR 1.18 × 102 to 6.7 × 106 IU/mL). No significant co-infection with other hepatitis viruses existed. All isolates were genotype D. Conclusions: The findings emphasize the role of unsafe injection practices in the community outbreak of hepatitis B infection, need to start routine surveillance system and increase awareness in health care workers regarding safe injection practices.

Abstract
In majority of individuals blood pressure rises in the early morning hours, which lead to serious cardiovascular complications. Formulation of pulsatile system makes it possible to deliver drug at definite period of time when symptoms of the disease condition are most critical. The purpose of the present work was to develop pulsatile release tablet of losartan potassium for chronotherapy in hypertension. The prepared system consisted of a core tablet coated with versatile and safe hydrophilic cellulosic ethers such as, hydroxypropyl methylcellulose, hydroxypropyl cellulose and sodium carboxy methylcellulose to produce burst release after predetermined lag time. Various formulation factors were studied through series of test and in vitro dissolution study. It was found that core tablets containing superdisintegrant failed to produce burst drug release pattern while effervescent agent was able to do so. Results also reveal that coating composition and coating level affects lag time. Formulation containing effervescent agent in core and coated with 200 mg hydroxypropyl cellulose provide lag time of 4.5 h with 73% drug release in 6 h that followed a sigmoidal release pattern. These values were close to the desired objective of producing lag time of 5-6 h followed by fast drug release. This approach can thus provide a useful means for timed release of losartan and is helpful for patients with morning surge.

Abstract
Widespread antenatal screening has resulted in increased detection of anomalies of the kidneys and urinary tract. The present guidelines update the recommendations published in 2000. Antenatal hydronephrosis (ANH) is transient and resolves by the third trimester in almost one-half cases. The presence of oligohydramnios and additional renal or extrarenal anomalies suggests significant pathology. All patients with ANH should undergo postnatal ultrasonography; the intensity of subsequent evaluation depends on anteroposterior diameter (APD) of the renal pelvis and/or Society for Fetal Urology (SFU) grading. Patients with postnatal APD exceeding 10 mm and/or SFU grade 3-4 should be screened for upper or lower urinary tract obstruction and vesicoureteric reflux (VUR). Infants with VUR should receive antibiotic prophylaxis through the first year of life, and their parents counseled regarding the risk of urinary tract infections. The management of patients with pelviureteric junction or vesicoureteric junction obstruction depends on clinical features and results of sequential ultrasonography and radionuclide renography. Surgery is considered in patients with increasing renal pelvic APD and/or an obstructed renogram with differential renal function <35-40% or its subsequent decline. Further studies are necessary to clarify the role of prenatal intervention, frequency of follow-up investigations and indications for surgery in these patients.

Abstract
Hepatitis E virus (HEV) is an emerging infectious threat to blood safety. In recent years, there have been a number of publications delineating this threat by providing evidence of the transmissibility of this virus through transfusions. The extent of transmission and its clinical relevance are issues under debate at present. HEV usually causes a self-limiting illness which subsides in a few weeks barring a few cases where fulminant hepatic failure occurs. The virus poses a risk of higher morbidity and mortality in pregnant females, patients with pre-existing liver disease and solid organ transplant recipients. As these categories of patient often require repeated transfusions or massive transfusions, they are exposed to a greater risk of transmission of HEV. At present, there is little evidence to advocate universal screening for this virus but considering that there is no definitive treatment for HEV induced hepatitis, selective screening should be advocated in blood products for high risk recipients in endemic areas.

Abstract
OBJECTIVE To compare the insertion characteristics, utilization profile, life span and the complication rates of Central lines (CL) and Peripherally inserted central lines (PICL). METHODS A prospective study of all CL or PICL insertions during January 2007 to September 2007 in the Neonatal Surgical Intensive Care Unit of a tertiary care center was done. The number of attempts, procedure time, duration of catheter stay, number of dressing done, complication during insertion and maintenance and cause of removal were noted and the differences analyzed statistically using Pearson chi square / t test. P value. 0.05 was considered significant. RESULTS Ninety two neonates were included in the present study of whom 60 were PICL insertions and 32 CL insertions. The two groups were comparable in terms of age, weight and the use of total perental nutrition (TPN) through the catheters. On comparing the PICL and CL groups, the number of attempts for successful insertion (p=0.003), the time taken (p=0.005), the number of dressing changes required during the indwelling period (p=0.005) and the overall complication rates (p=0.002) were significantly less in the PICL group. The PICL could be maintained for longer periods of time (p= 0.005) and only in 11.5% of the patients it had to be removed before completion of therapy as compared to 37.5% early removals for CL (p=0.02) CONCLUSION PICL is a safe, effective and reliable method of providing prolonged IV access in newborns. It also has the least incidence of complications during insertion and maintenance over prolonged period of time when compared to CL and should be recommended for routine use in neonatal surgical patients.

Abstract
Ulcerative colitis (UC) and Crohn's disease (CD) are considered to be immunologically mediated disorders that share certain features with murine models of colitis. Whether any of these models are physiologically relevant to the human condition remains controversial. The hypothesis is that increased amounts of antibodies neutralizing transforming growth factor (TGF)-beta, interleukin (IL)-2 or IL-10 create a relative immunodeficient state in inflammatory bowel disease (IBD) that predisposes to disease. To evaluate this, serum samples from patients with UC or CD and from normal healthy individuals were studied by enzyme-linked immunosorbent assays. Antibodies recognizing TGF-beta were most prevalent in UC (P<0.01); anti-IL-10 antibodies were elevated in CD (P<0.05), while anti-IL-2 antibodies were the same for all three groups. Importantly, the percentage of IBD patients with at least one of the antibody levels greater than any control value was 30% for UC and 33% for CD. To verify the presence of these antibodies, immobilized TGF-beta was exposed to UC sera and the attached proteins identified by Western blot assay. The proteins proved to be exclusively immunoglobulin (Ig) G. To evaluate the neutralizing activity of these antibodies, cytokine-specific IgG from subjects in each group of patients was incubated with TGF-beta, IL-2 or IL-10 before addition to a bioassay with changes in viability determined by a colorimetric analysis. Antibodies from most individuals in all three groups neutralized the action of each cytokine. This study shows that about one-third of IBD patients may have a relative deficiency of TGF-beta, IL-2 or IL-10 due to an increase in neutralizing antibodies in their sera.

Abstract
In recent past magnetic nanoparticles have been explored for a number of biomedical applications due to their superparamagnetic moment with high magnetic saturation value. For these biomedical applications, magnetic nanoparticles require being monodispersed so that the individual nanoparticle has almost identical physico-chemical properties for biodistribution, bioelimination and contrast imaging potential. Further, the surface functionalization/modification of magnetic nanoparticles ultimately facilitate the protein or DNA separation, detection and magnetic resonance imaging contrast, drug delivery and hyperthermia applications. The essential goal of this review is to evaluate the recent advances of magnetic nanoparticles for tumor, brain targeting and hyperthermia applications.

Abstract
Peak expiratory flow rate (PEFR) variability follows a specific pattern in asthmatics as well as in healthy individuals. There is scarcity of data for Indian healthy subjects. The PEFR (L/min.) was measured with Wright's portable peak flow meter at 05:00, 8:00, 11:00, 14:00, 17:00, 20:00 and 23:00 hours in 42 healthy, non-smoking adults of age group between 18-26 years. The variability of PEFR revealed a circadian pattern. PEFR levels tend to increase from morning at 5:00 hours till evening at 17:00 hours, with peak PEFR in evening at 17:00 hours, after which there was a progressive fall in PEFR levels, till morning 5:00 hours. This study provides the preliminary reference data of circadian pattern of PEFR in healthy individuals.
