Abstract
Hepatitis B virus (HBV) is mainly transmitted during birth or perinatal period, however, treatment is not usually recommended for pediatric patients with chronic hepatitis B (CHB). Twelve pediatric patients with CHB in Bangladesh were treated with both lamivudine and interferon. Lamivudine was given at a dose of 3 mg/kg, daily for 12 months. Two months after commencement of lamivudine therapy, all patents were given interferon-alpha (3 million IU/square meter of body surface area) three times weekly, subcutaneously for 10 months. Combination therapy was safe for all pediatric CHB patients. The levels of serum HBV DNA became undetectable (less than 500 copies/ml) in 8 patients and reduced in 4 patients after the end of therapy. Anti-HBe was detected in 10 of 12 patients at this time point. The levels of serum alanine aminotransferase (ALT) were significantly reduced in these patients (p less than 0.05) due to therapy. Neither flare of HBV DNA nor elevation of serum ALT were detected during follow-up. In conclusion, combination therapy with lamivudine and interferon-alpha represents a new and novel therapeutic option for treatment of pediatric CHB patients.

Abstract
Previous research using outbred rats indicates that individual differences in activity in a novel environment predict sensitivity to the reinforcing effect of psychostimulant drugs. The current study examined if the link between responses related to novelty and amphetamine self-administration is heritable. Twelve inbred rat strains were assessed for locomotor activity in a novel environment, preference for a novel environment, and intravenous amphetamine self-administration (acquisition, extinction and amphetamine-induced reinstatement). Strain differences were observed in activity in a novel environment, novelty preference and amphetamine self-administration, indicating a genetic influence for each of these behaviors. While there was no relation between activity in an inescapable novel environment and amphetamine self-administration, strain-dependent differences in novelty preference were positively correlated with the amount of amphetamine self-administered. There was also a positive correlation between the dose-dependent rate of amphetamine self-administration and magnitude of reinstatement. These results show that the activity in an inescapable novel environment and the preference for a novel environment are different genetically, and thus likely to reflect different behavioral constructs. Moreover, these results implicate a genetic influence on the relation between novelty seeking and stimulant self-administration, as well as on the relation between stimulant reward and reinstatement.

Abstract
BACKGROUND/AIM Ascariasis is a common parasitic infestation in Asia and Latin America. The most serious presentation is biliary and pancreatic ascariasis (BPA). The aim of the present study was to compare the clinical presentation of BPA with dead worms with that with living worms. MATERIALS AND METHODS We included 138 consecutive cases of BPA that occured during the period January 2005 to July 2009. All the patients had endoscopically proven BPA consisting of living or dead worms. Comparison was done by chi-square and independent t tests. RESULTS The age (mean +/- SD) of the patients was 36.8 +/- 16.1 years. Prevalence ratio between male and female patients was 1:5. Ninety eight patients contained living worms and 40 had dead worms. Males were more prone to develop dead worm BPA. The commonest presentation was biliary colic (131; 94.9%); others were acute cholangitis (30; 21.7%), obstructive jaundice (19; 13.8%), choledocholithiasis (20; 14.5%), acute pancreatitis (10; 7.2%), acute cholecystitis (6; 4.3%), liver abscess (2; 1.4%), hepatolithiasis (3; 2.2%), stricture of common bile duct (2; 1.4%), pancreatic abscess (1; 0.7%) and cirrhosis of liver (1; 0.7%). Choledocholithiasis, hepatolithiasis, liver abscess and cirrhosis were associated only with dead worms. We could successfully remove all the worms with endoscopic interventions, but 5 patients required surgical intervention as there were strictures and stones within the biliary tree or Ascaris were in gallbladder. Recurrences of stone and cholangitis occurred only in those with dead worms. CONCLUSION Biliary ascariasis with dead worms is more dangerous than that with living worms. Endoscopic or surgical intervention may be required repeatedly in those with dead worms.

Abstract
Aims-To investigate the level of matrix metalloproteinase activity during the time-course of cartilage explant proteoglycan breakdown; to determine the effects of selective small-molecule inhibitors of matrix metalloproteinases on proteoglycan degradation.Methods-The levels of matrix metalloproteinase activity in cartilage explant cultures and conditioned media were monitored by use of a quenched fluorescent substrate. The constants for inhibition of certain matrix metalloproteinases by a series of synthetic inhibitors were determined. Bovine and human cartilage explant cultures were treated with interleukin-1, tumor necrosis factor or retinoic acid and the amount of proteoglycan released into the culture medium in the absence and presence of the inhibitors was quantified. Control experiments, examining the inhibition of other proteinases, and investigating possible toxic or non-specific effects of the inhibitors, were carried out.Results-The profile of inhibition of proteoglycan release suggested the involvement of interstitial collagenase-like, rather than gelatinase- or possibly stromelysin-like, proteinases. No evidence was found for toxic or non-specific mechanisms of inhibition. Very low levels of activity of the known matrix metalloproteinases were present during the time-course of aggrecan breakdown.Conclusions-A novel collagenase-like proteinase(s) may be involved in cartilage proteoglycan breakdown. Gelatinase-type matrix metalloproteinases do not seem to be involved in this process. Specific collagenase inhibitors may be therapeutically efficacious in the treatment of arthritis.

Abstract
BACKGROUND Mutations in the Twinkle (PEO1) gene are a recognized cause of autosomal dominant progressive external ophthalmoplegia (adPEO), resulting in the accumulation of multiple mitochondrial DNA (mtDNA) deletions and cytochrome c oxidase (COX)-deficient fibers in skeletal muscle secondary to a disorder of mtDNA maintenance. Patients typically present with isolated extraocular muscle involvement, with little apparent evidence of the clinical heterogeneity documented in other mtDNA maintenance disorders, in particular POLG-related disease. METHODS We reviewed the clinical, histochemical, and molecular genetics analysis of 33 unreported patients from 26 families together with all previous cases described in the literature to define the clinical phenotype associated with PEO1 mutations. RESULTS Ptosis and ophthalmoparesis were almost universal clinical features among this cohort, with 52% (17/33) reporting fatigue and 33% (11/33) having mild proximal myopathy. Features consistent with CNS involvement were rarely described; however, in 24% (8/33) of the patients, cardiac abnormalities were reported. Mitochondrial histochemical changes observed in muscle showed remarkable variability, as did the secondary mtDNA deletions, which in some patients were only detected by PCR-based assays and not Southern blotting. Moreover, we report 7 novel PEO1 variants. CONCLUSIONS Our data suggest a shared clinical phenotype with variable mild multiorgan involvement, and that the contribution of PEO1 mutations as a cause of adPEO may well be underestimated. Direct sequencing of the PEO1 gene should be considered in adPEO patients prior to muscle biopsy.

Abstract
This study was done to determine the effectiveness of in situ extracorporeal shock wave lithotripsy (ESWL) in upper ureteric calculi in terms of stone clearance, peroperative & postoperative complications and also to determine some criteria for selection of patients for this procedure. From July, 2003 to July 2004, a total of 67 patients, with excreting kidneys and having stone size less than 2 cm were treated by in situ ESWL using Lithostar plus Lithotriptor. The patient group comprised of 52 men and 15 women, age ranged from 14 years to 65 years. Of the total 67 patients selected for study 44 patients were included in group I, having stone size ?1.5 and visible distal flow of contrast on IVU & 23 patients were included in Group II with stone size>1.5 cm to 2 cm and contrast seen only upto stone. Four (04) patients from Group I and three (03) patients from group II were dropped out during the follow up period so that data of 40 patients in group I and 20 patients in group II were analyzed finally. Number of shock wave was given in 1 to 3 sessions. Finally 95% of group I and 85% of group II achieved complete clearance of calculi at the end of 3 sessions. In situ ESWL is a good option for the treatment of upper ureteric calculi.

Abstract
Three unrelated children from ethnically diverse backgrounds who were treated for acute leukaemia became profoundly and irreversibly deaf during treatment. Aminoglycoside levels were within the therapeutic range. Genetic testing showed all three to have a maternally inherited mutation of mitochondrial DNA, m.1555A>G, known to cause sensitivity to the ototoxic effects of aminoglycosides. One child has received a cochlear implant, and another will be implanted shortly. Children diagnosed with acute leukaemia should be tested for this mutation at diagnosis, and alternative antibiotics chosen for the treatment of sepsis. Consideration should be given to elective testing of other groups of patients likely to receive aminoglycosides.

Abstract
<p><strong>Background: </strong>In general, it is assumed that patients with chronic hepatitis B virus (HBV) infection with high viral load exhibit increased liver damages. Accordingly, the treatment guidelines emphasize on reducing viral load in chronic HBV carriers. The ethical and scientific basis of these observations was mainly accumulated from investigations from developed countries of the world. More than 80% chronic HBV carriers live in the developing nations of the world, but little is known about relationship between HBV viral load and extent of liver damages in these countries. In this study, we addressed this issue to provide insights about this.</p> <p><strong>Methods: </strong>In this retrospective study we reviewed the records of 210 chronic hepatitis B (CHB) patients from our pool of 561 Bangladeshi CHB patients. All of these 210 patients had low HBV DNA (<10<sup>5</sup> copies/ml by PCR). Of them 16 were HBeAg +ve and rest 194 HBeAg -ve. They have also been tested for other serologic markers of HBV (i.e. HBsAg, anti-HBe), HCV (i.e. anti-HCV) and serum alaninetransaminase (ALT) level. All patients also underwent per-cutaneous liver biopsy.</p> <p><strong>Results: </strong>37.5% (6/16) HBeAg +ve patients with low HBV DNA had significant hepatic necro-inflammation (HAI-NI ≥7), whereas this figure was 31.44% (61/194) in case of HBeAg -ve patients. On the other hand significant hepatic fibrosis (HAI-F ≥3) was observed in 31.25% (5/16) and 14.4% (28/194) in HBeAg +ve and -ve patients respectively.</p> <p><strong>Conclusion: </strong>This study shows that a correlation could not be established between viral load and liver damage in patients with CHB in Bangladesh. A significant percentage of patients with low HBV DNA may have marked hepatic necro-inflammation and fibrosis, more so in case of HBeAg +ve CHB. Further study may be needed to find out the influence of other factors on liver damages in CHB patients in developing nations like Bangladesh, where about 8 million chronic HBV carriers are living. Most of these patients have not been characterized and treatment modalities have not been defined for them. Our study may suggest the research direction for management of these cases.</p> <p><strong>Key Words: </strong>Low HBV DNA; Chronic hepatitis B; Hepatic necro-inflammation; Hepatic fibrosis.</p><p>DOI: 10.3329/bsmmuj.v1i1.3693</p> <p><em>BSMMU J </em>2008; 1(1): 19-21</p>

Abstract
OBJECTIVE This study was designed to analyze the trends and differences in perinatal and neonatal mortality rates in the State of Qatar over a period of 30 years (1977 to 2007), to examine the causes of neonatal deaths and compare them with some regional Gulf states and developed world countries. STUDY DESIGN This is a retrospective study conducted in the Women's Hospital, Hamad Medical Corporation, State of Qatar from 1977 to 2007. METHOD The study included all perinatal and neonatal deaths for the period 1977 to 2007, which were monitored through registers of the Neonatal Intensive Care Unit (NICU), Women's hospital. Cause of death was determined using information from hospital records, including discharge certificates. There is a national database in the Department of Preventive Medicine that records all deaths through death certificates. The missing information for the early years was collected from this database. All causes of deaths were classified in accordance with criteria based on the International Classification of Disease tenth revision (ICD-10). RESULT There was a notable peak in neonatal (14.1), early neonatal (12.5) and perinatal (24.7) mortality rates in 1977. There was a second peak in neonatal (12.1) and late neonatal (7.5) mortality rates in 2000. Over a period of three decades (1977 to 2007), there was a significant decline in mortality rates (P<0.0001). By 2007, the neonatal mortality rate had decreased from 14.1 to 5.1; the early neonatal mortality rate had a dramatic fall from 12.5 to 2.3; and perinatal mortality came down from 24.7 to 10.3. There was no notable reduction in the late neonatal mortality rate in 2007 (2.8) compared with that in 1980 (3.0). The still-birth (8), neonatal (5), early neonatal (2.3) and perinatal (10.3) mortality rates in Qatar were very close to the rates found in developed countries, but lower than the rates in Bahrain and Saudi Arabia. Similar to developed countries, prematurity was the leading cause of neonatal death in Qatar (42.6%), followed by congenital anomalies (28%). CONCLUSION This study revealed that there was a sharp significant decline in neonatal and perinatal mortality rates during the study period in Qatar. The stillbirth, neonatal and perinatal mortality rates in Qatar are comparable with those in some of the developed countries and were lower than those in some of the Gulf countries. The proportion of underweight live births was found constant during the study period. Prematurity was the leading cause of neonatal death, followed by congenital anomalies.

Abstract
The present study was designed to investigate sedative and anxiolytic properties of the four different fractions (chloroform, pet ether, n-butanol and hydromethanol soluble fractions, coded as CFCB, PECB, NBCB and HMCB, respectively) of the aerial parts of Commelina benghalensis using rodent behavioral models, such as hole cross, open field and thiopental sodium induced sleeping time tests for sedative property and elevated plus-maze (EPM) test for anxiolytic potential, respectively. All fractions, at the doses of 200 mg/kg, p.o. and 400 mg/kg, p.o., displayed dose dependent suppression of motor activity, exploratory behavior (in hole cross and open field tests) and prolongation of thiopental induced sleeping time in mice; maximum effect was shown by chloroform (CFCB) and pet ether (PECB) fractions. In EPM test, chloroform (CFCB) and pet ether (PECB) fractions with similar doses significantly (p < 0.05) increased exploration to and time spent by the treated mice in EPM open arms in a way similar to that of diazepam while the effect of NBCB and HMCB fractions on entry to and time spent in open arms was not found to be statistically significant. These findings provide in vivo evidence that aerial parts of C. benghalensis in general, and chloroform (CFCB) and pet ether (PECB) soluble fraction has significant sedative and anxiolytic effects. Furthermore, these results may justify the scientific basis for the use of this plant in traditional medicine as a modality for anxiety and related disorders.
