Association of Posterior Reversible Encephalopathy Syndrome (PRES) with Preeclampsia with Severe Symptoms and Eclampsia in South East Part of Bangladesh

Posterior reversible encephalopathy syndrome (PRES) is a pathology seen not only in precelampsia with severe symptoms and eclampsia but in a varicty of diseases/ conditions. With the availability of neuroimaging, it is possible to know the exact underlying Central nervous system (CNS) pathology in preeclampsia with severe symptoms and eclampsia and thus therapy can be targeted. Preeclampsia with severe symptoms and eclampsia remains to be an important cause of maternal morbidity and mortality in both the developing and developed world. The objective of this study was to evaluate the association of Posterior reversible encephalopathy syndrome (PRES) by MRI (Magnetic resonance imaging) with preeclampsia with severe symptoms and eclampsia in south east part of Bangladesh. This cross-sectional observational study was performed among women suffering from preeclampsia with severe symptoms and eclampsia who attended at Obstetrics & Gynaecology department of Chittagong Medical College Hospital (CMCH), Bangladesh from January 2021 to June 2021. According to inclusion/exclusion criteria 50 samples were taken by convenient sampling for this study. A detail history was taken and complete general physical and gynecological examination was performed. Required data was collected through preset questionnaire. Neuroimaging reports were reviewed by both neurologist and radiologist. Data was analyzed by using windows based computer software device, SPSS 25.0. Results obtained from this study will be used to make a statement regarding aggressive management for cerebral vasospasm in severe preeclampsia and eclamptia related PRES. PRES has been reported to be reversible but late recognition or incorrect treatment can cause irreversible brain damage. Institution of early treatment leads to resolution of symptoms without any neurologic deficit and thus reduces maternal morbidity and mortality. PRES is a cliniconeuroradiologic entity. This study can aware doctors regarding prompt diagnosis of PRES in peripartum period among patient suffering from preeclampsia with severe symptoms and eclampsia by imaging aside clinical findings. A conclusive decision can be made to improve the outcome in this potentially life threatening but reversible condition.

"Screen and Treat" Approach among VIA Positive Women during Cervical Cancer Screening Program: Experience at Low Resource Setting

Cancer of the uterine cervix is one of the leading causes of mortality and morbidity among women in poor countries. It is the most common reproductive cancer among women in Bangladesh and most women are diagnosed at advanced stage when appropriate treatment is not possible. But this cancer is preventable through proper screening and simultaneous treatment of premalignant lesions. The same day "Screen and Treat" approach is an endeavour to reach the goal especially at low resource settings. Ablation of precancerous lesions by thermo-coagulation is a promising mode of complete cure as this method is easy to apply, effective and relatively cheaper than other procedures. To avoid the issue of overtreatment, an intermediate approach- colposcopy can be used. Aim of this study was to diagnose premalignant lesions of cervix during screening procedure and to treat the lesions by thermo-coagulation at the same sitting. This prospective study was carried out at Upzilla Health Complex (UHC), Rangunia, from 3rd February 2018 to 6th February 2018 in a campaign of cervical cancer screening program by visual inspection of cervix with 5.00% acetic acid (VIA). About 1000 women attending the outpatient department were enrolled in this study by consecutive sampling technique according to inclusion and exclusion criteria. Informed consent was taken after explaining the screening method, thermo-coagulation procedure and follow up schedule. VIA was found positive in 22 cases. Colposcopy was done in VIA positive cases by Gynocular colposcope. Punch biopsy was taken when colposcopy revealed positive in 12 women. Then thermo-coagulation was done. Histopathology report revealed, CIN1 (cervical intraepithelial neoplasia 1)- in 6 cases (50.00%); CIN 2 (cervical intraepithelial neoplasia 2)- in 01 case (8.33%); Chronic cervicitis with squamous metaplasia- in 05 cases (41.67%). Sensitivity and specificity of colposcopy was calculated considering colposcopy directed biopsy as gold standard, which was 100.00% and 75.00% respectively in CIN-1. While in CIN-2 it was 100.00% and 95.20% respectively. VIA is an effective screening tool for cancer cervix. Main advantage is the "screen and treat" approach can be attempted for at risk women in low resource setting by thermo-coagulation which is accepted by women while guaranteeing satisfactory cure rates. Thus, reduces loss to follow-up and have an impact on cervical cancer control.

Removal of Cu(II), Pb(II) and Cr(VI) ions from aqueous solution using amidoximated non-woven polyethylene-g-acrylonitrile fabric

Pre-irradiation method was applied to graft acrylonitrile (AN) onto non-woven polyethylene film. Graft yield reached 130% at 70 kGy radiation dose, 60% monomer concentration and 4 h reaction time when H₂SO₄ was used as an additive. The modification of AN grafted films with hydroxyl amine hydrochloride was done for the preparation of amidoxime adsorbent. The constructed adsorbent was characterized using FTIR, DMA and SEM. The amidoxime adsorbent was used for adsorption of Cu(II), Pb(II) and Cr(VI). Adsorption capacity was investigated under different conditions: contact time, pH and initial metal ion concentration. The optimum condition for maximum adsorption was found to be contact time 72 h and initial metal concentration 500 ppm for all the metal ions studied and pH 5.2 for Cu(II), 5.4 for Pb(II), 1.5 for Cr(VI). Kinetic adsorption data was elucidated using pseudo-first-order and pseudo-second-order equations. The equilibrium experimental data of metal adsorption matched Langmuir isotherm model. From the Langmuir equation, the monolayer saturation adsorption capacity (highest adsorption capacity) of the adsorbent was found to be 74.62 mg/g for Cu(II), 107 mg/g for Pb(II) and 156.25 mg/g for Cr(VI). The thermodynamics of metal adsorption was also investigated. Furthermore, desorption and reuse of the adsorbent film was studied. The results suggest that the adsorbent can be effective for adsorption of Cu(II), Pb(II) and Cr(VI).

Prevalence and the associated lesions of Cheilospirura (Acuaria) hamulosa in the indigenous chicken of Kashmir Valley, India

The present investigation reports the results from a 2-yr study conducted on the prevalence and associated lesions of the nematode Cheilospirura (Acuaria) hamulosa (Nematoda, Acuarioidea) in a sample size of 478 indigenous fowl collected from different localities of Kashmir Valley, India. The investigation revealed the annual prevalence for the nematode for the first and second yr of study to be 3.4% (8/233) and 3.7% (9/245), respectively, with an overall prevalence of 3.5% (17/478). Parasitized birds did not present with clinical signs. Despite the low parasite burdens, the lesions induced by C. hamulosa were severe. Histological examination of the infected gizzard revealed discrete and coalescing nodular and cystic lesions in the mucosa and musculature which contained sections of the parasite. Cellular reaction in the lesions was characterized by a large number of lymphocytes, monocytes, plasma cells, heterophils, and, in some of the sections, severe eosinophilic reaction. The mucosa and submucosa showed markedly thickened and diffuse mononuclear infiltration as well as reactive lymphoid nodules.
