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.

Short-segment versus Long-segment Stabilization for Unstable Thoracolumbar Junction Burst Fractures.

The treatment of unstable thoracolumbar junction burst fractures remains a controversial issue. We evaluate the efficacy of short segment (SS) compared with that of long-segment (LS) stabilization in terms of clinical and the radiological outcomes. Records of 88 patients with thoracolumbar burst fracture underwent posterior pedicle screw fixation from January 2004 to December 2015, studied retrospectively. These patients were divided into two groups: SS and the LS-group. Clinical parameters: back pain, disability, neurological deficit and radiologic parameters: Cobb angle, sagittal index, the kyphotic deformation of vertebral body, vertebral height and canal compromise were measured before surgery and immediately after surgery and at 3, 6 and 12 months postoperatively. Overall outcomes were evaluated using the modified Mcnab criteria at the last follow-up. Chi-squared test and paired-t test were used for statistical analysis using SPSS. There were 36 and 52 patients in the SS and LS- group, respectively. The mean age of the patients was 30.6±8.4 and 33.4±8.4 years and the mean follow-up period was 24.5 and 16.8 months in SS and LS-group respectively. In the SS-group, the fractured vertebral body level was L1, T12, L2, T11 and T10 in 15, 10, 6, 3 and 2 cases and LS- group, the fractured vertebral body level was L1, T12, L2, T11 and T10 in 22, 17, 5, 5 and 3 cases, respectively. Both groups achieved satisfactory clinical outcomes according to the modified Mcnab criteria. In the SS-group, 8(22.22%), 21(58.33%) and 7(19.44%) cases were considered to have excellent, good and fair outcome and LS-group, 18(34.61%), 25(48.08%), 6(11.54%) and 3(5.77%) cases were considered to have excellent, good, fair, and poor outcome, respectively. Short-segment pedicle screw fixation including the fractured vertebral body might be as effective as long-segment pedicle screw fixation for the treatment of unstable thoracolumbar junction burst fracture.

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.

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.

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.

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.

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.

Double migration of a schwannoma of thoracic spine.

Mobile intraspinal tumours have rarely been reported. In most cases, mobile tumours such as schwannomas or ependymomas were located in the cauda equina. Perusal of the literature revealed only two reports of mobile schwannomas in the cervical and thoracic regions. We report a case of thoracic schwannoma which migrated twice in successive operations resulting in negative exploration in the expected area. The aim of this report is to remind the surgeons about the possibility of migration of intradural-extramedullary tumour.

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.

Neolignans from North American Magnolia species with cyclooxygenase 2 inhibitory activity.

OBJECTIVES: Based upon reported ethnomedicinal use by Native Americans, extracts and pure isolates from leaves and seeds of Magnolia grandiflora, M. virginiana, M. acuminata and M. macrophylla, all native to the Southeastern United States, were investigated for their anti-inflammatory potential against cyclooxygenase 2 (COX-2). MATERIAL AND METHODS: The extracts and pure compounds from Magnolia species were tested for their production of prostaglandin E(2) (PGE(2)) using a mouse macrophage (RAW 264.7) assay where cells were stimulated by lipopolysaccharide. RESULTS: Leaf extracts were moderately active (44-58% inhibition at 50 microg/ml) whereas seed extracts showed significant activity of 54-88% inhibition, respectively. In the seed extract of M. grandiflora, honokiol, magnolol and 4'-O-methylhonokiol strongly inhibited COX-2 (IC(50): 1.2-2.0 microg/ml), 3-O-methylmagnolol was moderately active while a new compound was inactive towards COX-2. The neolignans were not cytotoxic to macrophages (RAW 264.7) and kidney fibroblast (VERO) cells in vitro. CONCLUSIONS: The results indicate that the reported ethnomedicinal use of the investigated Magnolia species is in agreement with anti-inflammatory activity of their respective compounds.

Transport of sennosides and sennidines from Cassia angustifolia and Cassia senna across Caco-2 monolayers--an in vitro model for intestinal absorption.

Laxative effects of Senna preparations are mainly mediated by rheinanthrone, a metabolite formed in the intestinal flora from dianthrones. Nevertheless, it was not clear whether dianthrones are bioavailable at all and contribute to the overall effects of this important medicinal plant. Using the Caco-2 human colonic cell line as an in vitro model of the human intestinal mucosal barrier, the bioavailability of dianthrones was studied in apical to basolateral (absorptive) and basolateral to apical (secretive) direction. Permeability coefficients (P(c)) and percent transport were calculated based on quantitations by HPLC. From the data obtained it was concluded that sennosides A and B, as well as their aglycones sennidine A and B are transported through the Caco-2 monolayers in a concentration-dependent manner and their transport was linear with time. The absorption in apical to basolateral direction was poor and P(c) values were comparable to mannitol. The transport was higher in the secretory direction, indicating a significant efflux (e.g. by efflux pumps) of the (poorly) absorbed compounds in the intestinal lumen again. Our findings support the general understanding that the laxative effects of Senna are explainable mainly by metabolites and not by the natively present dianthrones.
