Possible role of central interleukins on the anorexigenic effect of lipopolysaccharide in chicks.

1. The purpose of the present study was to determine if central interleukin-1ß (IL1ß), interleukin-6 (IL6) and interleukin-8 (IL8) affect feeding behaviour in chicks (Gallus gallus) and examine if central interleukins are related to the lipopolysaccharide (LPS)-induced anorexia. 2. Intra-abdominal (IA) injection of LPS significantly suppressed feeding behaviour and significantly increased mRNA expression of IL1ß and IL8 in the diencephalon when compared to the control group, while IL6 tended to be increased. 3. Intracerebroventricular (ICV) injection of 200 ng IL1ß significantly decreased food intake at 60 min after the injection while IL6 and IL8 had no effect. 4. IA injection of these ILs (200 ng) had no effect on food intake in chicks. 5. ICV injection of 200 ng IL1ß did not affect water intake and plasma corticosterone concentration, suggesting that central IL1ß might not be related to the regulation of drinking behaviour and the hypothalamus-pituitary-adrenal axis. 6. The present study demonstrated that central IL1ß but not IL6 and IL8 might be related to the inhibition of feeding in chicks.

Open-door Laminoplasty for Multilevel Cervical Spondylotic Myelopathy and Ossification of the Posterior Longitudinal Ligament (OPLL) using Titanium Reconstruction Miniplate and Screws.

To review outcome of 25 patients who underwent open-door cervical laminoplasty for multilevel cervical spondylotic myelopathy (MCSM) and ossification of the posterior longitudinal ligament (OPLL) using titanium reconstruction miniplate and screws. Records of 18 men and 7 women aged 35 to 78 (mean, 62.6) years were reviewed retrospectively from October 2009 and October 2014 at Bangabandhu Sheikh Mujib Medical University (BSMMU) and in our private settings, Dhaka, Bangladesh. Four patients had 5 levels (C3-C7), 21 patients had 4 levels (C3-C6) decompression and 3 patients (12%) performed foraminotomies. A total of 104 laminae were opened, all of them were fixed with a titanium reconstruction miniplates. In 21 patients, a 20-hole titanium miniplate bent to the contour of a lamina was used and fixed into 4 laminae and 4 patients fixed in 5 laminae levels. In most patients, screw fixation was unicortical and no spacer or bone graft was used. Demographic and surgical data were collected and clinical outcomes were assessed with neck pain score, neck disability index and Nurick's grading. Outcome analysis was done using Odom's criteria. The mean follow-up duration was 1.8 (range, 1-5) years. Diagnoses were MCSM (n=20), OPLL (n=5). Mean estimated blood loss (EBL) was 120ml (range: 50-200), mean surgery time was 153 min (range: 75-240). Following Nurick's grading, 23 patients (92%) improved, 2 (08%) had the same Nurick grade. No intraoperative complications were noted and average hospital stay was 6.12 days (range: 5 to 9). Significance improvements in overall NDI scores occurred at 1 year follow up (p<0.002). Radiographic evaluation showed an increase in the mean sagittal diameter from 13.3mm at pretreatment to 19.4mm post surgery. Two patients developed transient C5 palsy. Open-door Laminoplasty technique is safe, easy and achieves a good canal expansion and neurological recovery and can be used as an alternative treatment for cases of MCSM and OPLL patients without instability.

Surgical Outcome of Intradural Spinal Tumors.

Results of 63 surgically treated intradural spinal tumors between the period of October 2003 and December 2014 at Bangabandhu Sheikh Mujib Medical University (BSMMU) and in our private settings, Dhaka, were analyzed retrospectively. There were 33 males, 30 females with an average age of 52.4 years (13-70 years) and followed up for at least a year. The preoperative symptom with duration, tumors location and intradural space occupancy and the histopathological diagnosis were analyzed. Pain was evaluated by the visual analogue scale (VAS) and the neurologic function was assessed by Nurick's grade. The tumors were located as, thoracic (n=32, 50.79%), lumbar (n=16, 25.39%), cervical (n=05, 07.93%), and junctional (n=10, 15.87%, CervicoThoracic-01, Thoracolumbar-09). The histopathological diagnosis included schwannoma (n=30, 47.7%), meningiomas (n=14, 22.3%), neurofibroma, arachnoid cyst and myxopapillary ependymoma (n=03, 04.76%) each and paraganglioma (n=01, 01.59%). Among the intramedullary tumors, ependymoma (n=03, 04.76%), astrocytoma and epidermoid cyst (n=02, 03.17%), haemangioblastoma, paraganglioma and cavernous haemangioma (n=01, 01.59%) each. The VAS score was reduced in all cases from 8.0±1.2 to 1.2±0.8 (p<0.003) and the Nurick's grade was improved in all cases from 3.0±1.3 to 1.0±0.0 (p<0.005). The preoperative neurological deficit improved within 8 postoperative weeks in most cases and within 1 postoperative year in all cases. Complications included cerebrospinal fluid leakage, parasthesia and further neurological deterioration (Astrocytoma) (n=02, 03.17%) and dependant bedsore and recurrence (Ependymoma) (n=01, 01.59%). Aggressive surgical excision potentially minimizes neurologic morbidity and improved outcome except intramedullary tumors where initial treatment consists of maximum safe surgical resection or biopsy.

Acne vulgaris related to androgens - a review.

Sebum production is stimulated by androgens and is the key in the development of acne vulgaris. Several investigators have looked for direct relationships between serum androgen levels, sebum secretion rate and the presence of acne. The presence of acne in prepubertal girls and sebum production in both sexes correlate with serum dehydroepiandrosterone sulfate (DHEAS) levels. Although increased serum androgen levels correlate with the presence of severe nodular acne in men and women, these levels are often within the normal range in mild to moderate acne. This raises the question of whether there is an increased local production of androgens within the sebaceous gland of patients with acne vulgaris that leads to increased sebum secretion.

Association of rheumatoid factor and uric acid with psoriatic arthritis: a review.

Psoriatic arthritis is a condition that causes inflammation of the joints of psoriatic patients. Psoriatic arthritis also affects tissues surrounding the joints including tendon and ligaments. Psoriatic arthritis (PsA), recognized for over 100 years, is the second most frequent diagnostic category after Rhematoid Arthritis (RA) and occurring up to 10% of patients with skin psoriasis. Although PsA is a sero-negative arthritis and the absence of rheumatoid factor is a characteristic laboratory finding, it may be present in 3% of psoriatic arthritis (PsA) patients. Hyperuricaemia has been generally accepted as a frequent accompaniment of psoriasis and psoriatic arthritis. It has been postulated that the hyperuricaemia results from increased purine synthesis from the rapid epidermal cell turnover. With its uniquely diverse pathophysiologic and clinical features and the ability to progress into one of the most destructive arthritis known as, psoriatic arthritis (PsA), remains a challenging disease deserving of the attention in recent years. High level of serum uric acid is a risk factor for many diseases like gout, hypertension, coronary heart diseases etc. Patients with PsA remain vulnerable for many diseases like above mentioned one. So, hyperurecemia may play a vicious link with PsA and gout, hypertension and so many diseases. This article may help all dermatologists and researchers for further evaluation of serum uric acid and RA factor in psoriatic arthritis (PsA) patients.

Prevalence and distribution of different diarrhoeagenic Escherichia coli virulotypes in major water bodies in Bangladesh.

Escherichia coli, a prominent waterborne pathogen, causes a variety of gastrointestinal and extraintestinal infections that depend on virulence determinants. To monitor natural aquatic systems for virulence-associated genes of E. coli, multiplex PCR was used in a survey covering 46 major natural water bodies in Bangladesh. DNA was extracted directly from water samples as well as from pre-enriched and enriched cultures during three successive seasons and assessed for E. coli virulotype distribution. From the five virulotypes, genes from the enterotoxigenic (ETEC), enteropathogenic (EPEC), and enterohaemorrhagic (EHEC) virulotypes were detected consistently, but genes from the enteroinvasive (EIEC) and enteroaggregative (EAEC) virulotypes were traced only occasionally. ETEC was the most prevalent virulotype, followed by EPEC. However, EIEC and EAEC virulotypes could not be detected in winter or the rainy season, respectively. Specific regional distribution patterns of different E. coli virulotypes and their temporal fluctuations were identified. These observations may assist with assessing seasonal risk and identifying vulnerable areas of the country prone to E. coli-associated outbreaks.

Efficacy of levamisole for the treatment of slow spreading vitiligo.

Levamisole can be used as an immunomodifier for an effective treatment of vitiligo. A clinical trial was done to assess the efficacy of levamisole in patients of vitiligo. The study was conducted in the department of Dermatology and Venereology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2010 to July 2011. A total number of sixty patients were assigned purposively. Among them thirty patients were belonged to Group A, treated with levamisole alone and another thirty patients belonged to Group B, treated with levamisole 160 mg weekly with topical 0.1% fluocinolone acetonide acetate on the lesions once a day for a duration of 6 months. Patients were followed up every 2 weeks interval and were continued up to 6 weeks. Out of all patients from group A, the mean sizes of the lesions were 8.17cm before treatment but 5.90cm, 4.32cm, and 3.57cm at 1st visit, 2nd visit and 3rd visit respectively after treatment. In Group B, the mean sizes of the lesions were 7.50cm before treatment but 4.92cm, 3.00cm, and 4.75cm at 1st visit, 2nd visit and 3rd visit respectively after treatment. Among the respondents of Group A & B, 25(83.3%) and 27(90%) were cured respectively. This study observed that Levamisol with topical 0.1% fluocinolone was more responsive in percentage but the difference was not statistically significant.

Comparative efficacy of hydroxyurea and methotrexate in treating psoriasis.

A clinical trial study in the treatment of psoriasis was conducted in twenty three patients. The patients of psoriasis attending at the department of Dermatology and Venereology, BSMMU, Dhaka during the period of July 2009 to May 2010 were enrolled in this study. Eleven patients were treated with oral hydroxyurea (case), belonged to Group A and rest 13 patients were treated with oral methotrexate (control), belonged to Group B. Elements of the Psoriasis Area and Severity Index (PASI) were calculated as main outcome measure at baseline; follow up after 4 weeks and finally at 8 weeks. The mean PASI score for the Group A patients was 17.0±7 and that of Group B patients was 13.8±3. The mean reduction was higher among the Group B patients (11.8±3.5) than the Group A patients (13.5±6.8), but the mean reduction was not statistically significant (p>0.05) between two groups of patients. The mean percentage of decrease of PASI score was found to be high among the Group B patients (84.9±10.4, i.e. 85%) than the Group A patients (77.6±14.0, i.e. 78%), but the mean difference was not statistically significant (p>0.05). Analysis revealed that a statistically significant improvement of psoriasis was observed based on PASI score eight weeks of treatment in both treatment group (p=0.001). There was no statistically significant mean difference was found between Group A and Group B patients in terms of blood hemoglobin, erythrocyte sedimentation rate, WBC and platelet count and serum ALT (p>0.05). The current study showed adverse effects in 7(63%) patients of Group A and 8(66.6%) patients of Group B. In both groups of patients the adverse effects were few and mild in nature. So hydroxyurea can be alternative drug to methotrexate in the treatment of psoriasis.

Comparative efficacy of methotrexate and mini pulse betamethasone in the treatment of lichen planus.

A clinical trial was conducted to evaluate the efficacy of methotrexate and mini pulse betamethasone in the treatment of lichen planus. A total of forty four patients of lichen planus, attending at the department of Dermatology and Venereology, BSMMU, Dhaka, Bangladesh during the period of January 2009 to December 2010 were enrolled in this study. Of them, 23 patients in Group A (case) and 21 patients in Group B (control) were selected. The case was treated with oral methotrexate and the control was treated with betamethasone oral mini-pulse therapy. Efficacy of drugs were measured to assess the improvement of mucocutaneous lesions, to change the colour of the lesions which became violaceous to postinflammatory hyperpigmentation, remission of itching, disappearance of existing lesions and stop appearance of new lession after initiation of treatment at 1st week, 2nd week, 6th week and 12th week. At the end of the present study, it was found that 16(69.6%) patients in cases completely cured the disease, whereas 10(47.6%) patients among the control cured the disease. Data showed that moderate remission was higher among the control 6(28.6%) compared to cases 5(21.7%) and the partial remission was also higher among the control 5(23.8%) compared to cases 2(8.7%). However, the efficacy was better in patients taking methotrexate and it also showed that macular and papular lesion responded well than plaque type lesion. Differences in treatment outcome were seen better in methotrexate group but the difference was not statistically significant.

Instrumented posterior lumbar interbody fusion (PLIF) with interbody fusion device (Cage) in degenerative disc disease (DDD): 3 years outcome.

This prospective interventional study carried out at Bangabandhu Sheikh Mujib Medical University and a private hospital in Dhaka, Bangladesh during the period from October 2003 to September 2011. Surgical treatment of degenerative disc disease (DDD) should aim to re-expand the interbody space and stabilize until fusion is complete. The present study conducted to find out the efficacy of using interbody fusion device (Cage) to achieve interbody space re-expansion and fusion in surgical management of DDD. We have performed the interventional study on 53 patients, 42 female and 11 male, with age between 40 to 67 years. All the patients were followed up for 36 to 60 months (average 48 months). Forty seven patients were with spondylolisthesis and 06 with desiccated disc. All subjects were evaluated with regard to immediate and long term complications, radiological fusion and interbody space re-expansion and maintenance. The clinical outcome (pain and disability) was scored by standard pre and postoperative questionnaires. Intrusion, extrusion and migration of the interbody fusion cage were also assessed. Forty seven patients were considered to have satisfactory outcome in at least 36 months follow up. Pseudoarthrosis developed in 04 cases and 06 patients developed complications. In this series posterior lumbar interbody fusion (PLIF) with interbody cage and instrumentation in DDD showed significant fusion rate and maintenance of interbody space. Satisfactory outcome observed in 88.68% cases.

Traumatic gut injury: a study of 100 cases in Mymensingh Medical College Hospital.

This study was done to find out the mode of presentations, management options and the factors which dictate the out-come of the patients with traumatic gut injury. It has been carried out in the department of Surgery, Mymensingh Medical College Hospital in 100 patients with traumatic gut injury from January 2009 to December 2010. Most of the patients were within 21-30 years (47%) and male patients were the predominant group (90%). In this study penetrating injury was more common (57%) than non-penetrating (43%) injury as a cause of gut injury. Stab (64.91%) was the main mechanism of penetrating abdominal trauma; while road traffic (58.14%) was the main mechanism of non-penetrating abdominal trauma. Diagnosis was made on clinical presentation, physical examination and some investigations. Abdominal pain (98%) was the chief complain and chief sign was abdominal tenderness (98%) and absent bowel sound (91%). Small gut injury was present in 71% patients, 20% patients had large gut injury and 9% had both gut injury. In small gut, jejunum (49.29%) was the most vulnerable portion and right sided colon (55%) was the most affected portion in large gut trauma. Spectrum of injury in small gut included single perforation (63%), multiple perforations (23%), laceration (11%) and devascularization (3%) injury. Primary repair in 60.87%, resection & anastomosis in 27.54% and resection anastomosis with proximal diversion in 11.59% patients were done in small gut injury. Injuries in the large gut were classified into three categories according to Flint Colon Injury Severity Scoring. Highest incidence was in Grade I (60%) category, second in Grade II (35%) and Grade III (5%) was the third one. Simple primary repair in 40%, primary repair or resection anastomosis with proximal diversion in 30%, loop ileostomy in 20% and Hartman's procedure in 10% were done in patients of large gut injury. Resection anastomosis with proximal diversion was performed in patients of both small and large gut injury. Outcome of management was quiet acceptable with 47% of patients having uneventful recovery. Delayed presentation, delayed definitive management, haemodynamically unstable patient, site and number of injuries in the gut were the crucial factor for the overall 44% morbidities of this series. Morbidity rate was 9%. More than half of the patients (56.04%) discharged from the hospital within 10 days. Only a few patients could be followed up for a few months after surgery, who reported to have a satisfactory outcome with no morbidity.

Safety of low molecular weight heparin in the treatment of cutaneous lichen planus.

An interventional study was undertaken to assess the safety of low molecular weight heparin in the treatment of lichen planus. Data were collected from the department of Dermatology and Venereology, Combined Military Hospital (CMH), Dhaka, Bangladesh for a period from July 2009 to June 2010. During the data collection period, thirty seven patients of lichen planus were assigned purposively. The mean age of the patients was 36 ± 6.6 years and highest percentage of patients, 21(56.8%) were in between the 30-40 years old, majority of patients 32(86.5%) were male, two thirds of patients 24(64.9%) were married and majority of the patients 29(78.4%) were service holders. It was seen that about half of the patients 18(48.6%) had complaints of itching, maximum 12(32.4%) had involvement of shin area and 21(56.8%) suffered for a duration of 1 to 11 months. The study revealed that 29(78.4%) patients yielded no side effect, while 8(21.6%) developed local irritation 5(62.5%), bruises 2(25.0%) and headache 1(12.5%). The side-effects however disappeared spontaneously without medication. The study suggests that low molecular weight heparin has excellent safety profile for treatment option of cutaneous lichen planus.

Profile of infertility status of male in Dhaka city.

A cross sectional study was done to determine the important etiological profile of infertility status of male in Dhaka city. A total of eighty seven patients of male infertility were selected purposively. Among them, highest percentage of patients, 44(50.6%) were in between the 21-30 years old, 36(41.4%) had 6-10 years of post- marriage duration, 56(64.4%) patients stated that they stayed with their wife interruptedly, 54(62.1%) had primary infertility and 33(37.9%) had secondary infertility. It was found that among the patients 6(5.50%) had anti-sperm antibody, 45(40.9%) had sexually transmitted disease (STD), 41(37.3%) had varicocele, 2(1.80%) had loss of libido, 4(3.6%) had premature ejaculation and 12(10.9%) had hydrocele. It was observed that 14(12.7%) were tobacco user, 26(23.6%) were obese, 12(10.9%) had malnutrition, 7(6.4%) had exposure to heat etc and it was found that 61(70.1%) had free testosterone below the normal level and 51(58.6%) had prolactin level above the normal level. The semen analysis revealed that 48(55.2 %) had abnormal morphology of sperm, 26(29.9%) had feebly motile sperm and 27(31%) had non-motile sperm, 36(41.4%) had oligospermia, 6(6.9%) had azoospermia and 17(19.5%) had oligoasthenozoospermia.

Efficacy of topical application of Pimecrolimus cream in the treatment of discoid lupus erythematosus.

The interventional type of study to assess the efficacy of Pimecrolimus cream in the treatment of patient of localized discoid lupus erythematosus (DLE) was carried out for a period of July 2008 to June 2009. It was observed that before treatment, erythema was severe in 43.2% cases, moderate in 51.4% cases and mild type erythema was present in 5.4% cases. The post- treatment revealed, 29.7% severe type erythema, none evidenced moderate type erythema, only 43.2% had mild type and 27% cases no erythema at all. Before treatment, infiltration was severe in 27% cases, moderate in 54.1% cases and only 18.9% had mild type infiltration. But after treatment, 10.8% had severe type infiltration, 18.9% had moderate, 51.4% had mild and 18.9% had no infiltration at all. Similar response to treatment was noticed with squamation which exhibited a drop from 37.8% to 18.9% in severe cases and from 62.2% to 10.8% in moderate cases. There was a 45.9% mild case and 24.3% had no squamation. The scoring result of photosensitivity, itching, disfigurement evidenced analogously score reduction of 2.0, 3.05 and 3.12 respectively. In conclusion, it was interpreted that score of patients of DLE, before treatment was 6.83 ± 1.30 and after treatment was 3.83 ± 1.18. Unpaired 't' test was found statistically significant (p<0.05) between before and after treatment by drug. Improvement was shown in 26(70.27%) cases and 11(29.73%) cases shown no improvement at all. Marked improvement observed on the 2nd follow up visit at the end of 12 weeks. Response was good in 23(88.46%) cases, fair 2(7.69%) and poor 1(3.85%) cases. The study suggests that pimecrolimus 1% cream has significant efficacy profile for treatment option of cutaneous lupus erythematosus.

Non-culture diagnosis of Chlamydia trachomatis genital infection in sexually active women.

Infections caused by Chlamydia trachomatis (CT) are one of the most prevalent of all sexually transmitted diseases (STD). This cross sectional study was carried out to diagnose genital CT infection on 108 (59 pregnant and 49 non-pregnant) women attending at Department of Gynaecology and Obstetrics, Mymensingh Medical College Hospital (MMCH) during the period from January 2009 to December 2009. This non- culture technique was based on detection of CT major outer membrane protein (MOMP) by Direct Fluorescence Antibody Test (DFAT) from endocervical swab. Chlamydial inclusion bodies (IB) were looked for using Iodine stain. CT antigens were detected in 45.3% (49/108) cases by DFAT; IBs were detected in 5.5% cases (06/108) by Iodine staining technique. Majority of CT positive cases (65%) were found in the younger age group (15 to 25 years). The CT infection was found 47.2 % (35/74) in symptomatic cases, 41.1% (14/34) in asymptomatic cases and 47.4% in pregnant group, 42.8% in non-pregnant group. Although high incidence of genital chlamydia infection is common both in pregnant, non-pregnant, symptomatic and asymptomatic women in Bangladesh an early and reliable diagnostic method for genital chlamydia infection in Bangladesh should be further explored.

Pattern of Glomerular Disease in a Tertiary Care Hospital of Bangladesh.

Glomerular disease is one of the most important causes of chronic kidney disease in developing countries like Bangladesh as well as the whole world. The pattern of glomerular disease varies in different countries and can have different clinical presentations. The aim of the study was to analyze the clinical profile and to determine the histological pattern of glomerular diseases in a large tertiary care hospital in Bangladesh. All kidney biopsies performed in Mymensingh Medical College Hospital, Bangladesh from October 2018 to March 2020 were prospectively analyzed in the study. A total of 101 patients with kidney biopsy were examined by clinical and laboratory findings and by light and immuno-fluorescence microscopy. The mean age was 30.0±14.6 years and 50(49.5%) were male and 51(50.5%) were female with a male to female ratio of 1:1. The clinical syndromes namely nephrotic syndrome, nephritic syndrome, nephrito-nephrotic presentation, RPGN like presentation, macroscopic haematuria and asymptomatic urine abnormality were present in 31.7%, 34.5%, 22.8%, 11.9%, 19.8% and 10.9% patients respectively. The most common histological varieties found in the study were mesangial proliferative glomerulonephritis (MesPGN) (18.8%) and focal segmental glomerulosclerosis (FSGS) (18.8%). Other histopathological pattern among the studied subjects revealed minimal change disease (MCD) in 5.9%, membranous nephropathy (MN) in 7.9%, membranoproliferative glomerulonephritis (MPGN) in 16.8%, IgA nephropathy in 5%, IgM nephropathy in 2%, IgG nephropathy in 2%, diffuse proliferative glomerulonephritis (DPGN) in 1%, focal proliferative glomerulo-nephritis (FPGN) in 3%, crescentic GN in 3%, lupus nephritis (LN) in 13.9%, amyloidosis in 1% and fibrillary glomerulopathy in 1% patient. The pattern of glomerular disease found in this study was similar to other studies performed in Bangladesh with a little variation. It may guide the future researchers to establish a national kidney biopsy registry in Bangladesh.

Surgical Outcome of CSF Drainage in Paediatric Obstructive Hydrocephalus.

Hydrocephalus (HCP) is occurred when there is inequality in the formation and absorption of CSF to such a level which causes accumulation of fluid and causing raised intracranial pressure. Hydrocephalus is the most frequent neurosurgical problem encountered in the paediatric age group. CSF diversion surgically is needed as treatment for certain condition. Endoscopic third ventriculostomy (ETV) and Ventriculo-peritoneal shunt (VPS) are most widely used CSF diversion procedure. Therefore, this study was conducted for comparing the surgical outcome of ETV and VP shunt in obstructive hydrocephalus. This is a prospective experimental study conducted in the Department of Neurosurgery, Dhaka Medical College and Hospital (DMCH) and Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2017 to December 2019. Paediatric patients of both sex and 6 months to 18 years of age with obstructive hydrocephalus undergone endoscopic third ventriculostomy (ETV) or ventriculo-peritoneal shunt (VP shunt) were included after fulfilling inclusion and exclusion criteria. The patients divided into two groups (Group A and Group B). The Group A included 30 patients who treated by Endoscopic third ventriculostomy and the Group B include 30 patients, who was treated by Ventriculo-peritoneal shunt. Surgical outcome was analyzed in two procedures separately. In Group A (ETV group) symptomatic improvement, GCS score improves earlier and post-operative complications relatively less than Group B (VP shunt group). But in VP shunt group 3 months follow up reveals- improvement of papilledema, Occipital frontal circumference (OFC) regression and fontanelle size improvement was more than that of ETV group. This study concluded with suggesting that Endoscopic third ventriculostomy (ETV) is technologically superior surgical technique than VP shunt. Though ETV showed relatively more immediate procedural failure and intraventricular hemorrhage but long-term outcome is better and also associated with lower incidence of infection and re-operation in comparison to VP shunt.

Endoscopic third ventriculostomy in children: problems and surgical outcome: analysis of 34 cases.

BACKGROUND: Endoscopic third ventriculostomy (ETV) has been established as a viable treatment option for obstructive hydrocephalus of children over 6 weeks of age. ETV in pediatric groups may be unsuccessful due to the failure of absorption of cerebrospinal fluid (CSF) or reclosure of ventriculostomy stoma or due to infection. The exact cause is still debatable. Some issues like failure to eliminate the second membrane during the procedure or formation of the new arachnoid membrane at the stoma are still not clear. This study aims to assess the surgical failure of ETV and its predisposing factors. METHODS: Thirty-four pediatric patients with hydrocephalus were analyzed retrospectively. The patients' age limit was between 2.5 months and 14 years. This is a retrospective study of 34 patients in a single private hospital between June 2012 and January 2018. Patients having hydrocephalus in pediatric groups more than 6 weeks of age were included in the study. RESULTS: The mean age of all patients was 51.25 ± 53.90 months and the mean follow-up period was 50.47 ± 20.84 months. Of 34 surgeries, the success rate was 79% and the failure rate was 21%. Within 2 years, the success rate was 68.42% and above 2 years' success rate was 93.33%. In this series, 7 cases of ETV were re-explored and found ventriculostomy stoma closure in 3 cases, the presence of the second membrane in re-exploration 2 cases, and presence of inflammatory arachnoid membrane in re-exploration 2 cases. The use of dexamethasone around the stoma in inflammatory stoma was useful, having no recurrence. In one patient of the second membrane probably due to absorption failure in communicating hydrocephalus re-exploration was failed and was managed successfully with VP shunt. CONCLUSIONS: Predisposing factors causing ETV failure are ventriculostomy stoma closure by new arachnoid granulation tissues, remnants of the second membrane inside the stoma, CSF absorption failure, infection/high protein in CSF and inappropriate patient selection.

Combination therapy of lamivudine and interferon-alpha in pediatric patients with chronic hepatitis B in Bangladesh: a safe and effective therapeutic approach for pediatric CHB patients in developing countries.

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.

Profile of lichen planus in Bangladesh.

Lichen planus is one of the common inflammatory disorders of skin, mucous membrane, nail and hair characterized by violaceous, polish, pruritic, polygonal, flat-topped papules usually distributed bilaterally symmetrically over the extremities. Our objectives in this study were to explore the prevalence of lichen planus in large area of Dhaka in Bangladesh and to establish the clinical characteristics of lichen planus. This descriptive type of cross sectional study was carried out from September 2006 to August 2008 in the Department of Dermatology and Venereology of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Medical College Hospital (DMCH) and Combined Military Hospital (CMH) in Dhaka. Patients suffering from lichen planus were selected as study population. By face to face interview and clinical observations, data were collected from sample. A total 120 patients of lichen planus were selected, on the basis of age, 30(25%) were 10-30 years of age, 75(62.56%) were 30-50 years and 16(13.33%) were over 50 years of age. The mean age of the patient was 40+/-4 years. Out of 120 patients, 80(66.66%) were male and 60(33.33%) were female and eight patients (6.67%) had positive family history among highest age group (30 to 50 years). In case of duration of disease, highest percentage (68%) of cases was 15 days to 6 months and considering clinical sign, koebnerization was present 45(37.5%) cases and Wickhams striae 22(18.33%) cases. Regarding site of onset of lesion, lesions were highest 100(83.33%) in upper limbs, next lower limbs, trunk, oral mucosa etc. The distribution of clinical pattern of lichen planus showing classic pattern (68.33%) was the most common type, followed by hypertrophic, actinic, ashy dermatoses, lichen plano-pilaris, erosive or ulcerative etc. This clinico-epidemiological study of lichen planus attending in the different hospital in Dhaka, Bangladesh has shown that lichen planus is usually associated with 30 to 50 years of age group, with higher male prevalence than female, 15 days to 6 months are mainly duration of disease, koebnerization and Wickhams striae are common clinical signs, upper limbs is mainly the site of onset of lesion, and classic pattern is the most common clinical type in lichen planus.
