The case of primary ovarian ectopic

Ovarian ectopic pregnancy is a rare form of ectopic pregnancy. It mimics tubal ectopic, difficult to distinguish on ultrasound imaging and clinical presentation. It mostly presents with rupture in first trimester. We presented this case in view of its varied tricky clinical presentation- which lead us into various differential diagnoses for pain abdomen and the least suspicion of an ovarian pregnancy. Laparoscopic management is needed for diagnosis and confirmation is only through a histopathological diagnosis. Even though it’s rare, still we need to be suspicious of this in all patients with acute lower abdominal pain and with no period of amenorrhoea.

Experimental Investigations on Applicability of Eco Friendly, Green and Sustainable Farm/Fish Pond Liner As A Component for Water Storage System

It is a well-known fact that in most of the regions, rainfall shall not meet the crop water requirements. Hence it is very much necessary to have water storage system to meet the water demand. The rate of seepage is considered to be high in case of earth ponds. By considering this, there is an urgent requirement to reduce the seepage in the water storage system and increase the irrigation efficiency. This research studies is based on minimizing the seepage in the ponds by providing a liner material, which is eco-friendly, sustainable, economic with good serviceability.  In this experiment the sodium based salts are used in combination with Bauxite Mine Residue (BMR) and Ordinary Portland Cement (OPC) as binder materials for the liner system to decrease the seepage. Three proportions of the binder were used in the study viz. BMR: OPC as 80:20. Sodium carbonate (SC) was used in the proportion of 0%, 2% 4%, 6% 8% 10% and 12% by weight of binder. SEM analysis, pH permeability and compaction tests were conducted to determine the performance of the liner material. Results showed that the binder ratio of BMR: OPC with ratio 80:20 with sodium carbonate content 10% showed the better results with more reduction in seepage, maximum reduction in permeability. Hence the present studies prove that the produced pond liner shall reduce seepage effectively and have more serviceability compared to plastic liners

Electrocatalytic oxidation of methanol on Ni modified polyaniline electrode in alkaline medium

Electrolytically deposited Ni on polyaniline film covered carbon paste electrode (Ni/PANI/CPE) was used as anode for the electrooxidation of methanol in alkaline medium. The electrochemical behavior and electrocatalytic activity of the electrode were studied using cyclic voltammetry, impedance spectroscopy, chronomethods, and polarization studies. The morphology and composition of the modified film were obtained using scanning electron microscope and energy dispersive X-ray analysis techniques. The electrooxidation of methanol in NaOH was found to be more efficient on Ni/PANI/CPE than on bare Ni, electrodeposited Ni on Pt, Ni on glassy carbon, and Ni on CPE substrates. Partial chemical displacement of dispersed Ni on PANI with Pt or Pd further improved its performance towards methanol oxidation. © 2010 Springer-Verlag

Electrocatalytic oxidation of methanol on Pt modified polyaniline in alkaline medium

A comparative study of the electrocatalytic oxidation of methanol is made in NaOH, Na2CO3 and NaHCO3 on bare Pt (Pt), polyaniline covered Pt (PANI) and Pt modified polyaniline film on Pt (Pt/PANI) using cyclic voltammetry, polarization, ac impedance spectroscopy and chronoamperometric techniques at 25 °C. The cyclic voltammetry and polarization studies show that the potentials at which methanol oxidation commences on different electrodes in each of the alkaline medium examined follow the trend Pt/PANI < Pt < PANI whereas the potentials for initiation of oxidation on each electrode in different alkaline media follow the order NaHCO3 > Na2CO3 > NaOH. The oxidation current is highest and charge transfer resistance lowest for Pt/PANI films compared to Pt in all the media studied. However, for the same Pt loading Pt/PANI films exhibit larger oxidation currents in NaOH followed by Na2CO3 and NaHCO3. The Tafel slope for methanol oxidation on Pt/PANI in NaOH, Na2CO3 and NaHCO3 has a value of about 115 mV decade-1. The chronoamperometric response of the Pt/PANI film at the peak potential for methanol oxidation shows lesser sensitivity to poisoning by CO compared to bare Pt and platinised Pt (Pt/Pt). © 2008 Elsevier B.V.

A rare case report of gestational trophoblastic disease in peri menopausal women

Benign gestational trophoblastic disease (GTD) generally occurs in reproductive age group women; but is extremely rare in peri and post-menopausal women. We report a case of molar pregnancy in a 48-year-old lady with complaints of bleeding per vaginum with severe pain abdomen. The intention was to highlight the need to include GTD as a possible cause of abnormal bleeding per vaginum in peri and post-menopausal women. So early diagnosis and management with proper follow up is possible. It stresses the need for early recognition to avoid high malignant sequelae

The method is mild and inexpensive; yields are high and the reactions go to completion within 10–15 min

Multidrug resistant tuberculous meningitis in pregnancy: a rare case report

The prevalence of tuberculosis, especially extrapulmonary tuberculosis is increasing worldwide. TB meningitis is one of severe manifestations of extra pulmonary TB. Prognosis of cases of multidrug resistance tuberculosis meningitis is worse and even more challenging in pregnant women. It’s mostly associated with increased frequency of maternal disability, hospitalisation during pregnancy, foetal growth retardation, prematurity, low-birth weight and increased perinatal mortality. As information on outcome of pregnancy among women with extra pulmonary TB is limited; various medical and surgical options for timely management has been discussed. Authors bring out a case report of a primigravida at 26 weeks gestation with severe multidrug resistant TB meningitis who was successfully managed at our hospital with a healthy infant.

Electrothermoconvective instability in a heat generating dielectric fluid layer

The combined effects of vertical d.c. electric field and uniform internal heat generation on the onset of convection in a horizontal poorly conducting dielectric fluid layer heated uniformly from below are investigated. The Galerkin method is used to solve the resulting eigenvalue problem. Parametric study is conducted to know the effects of varying electric Rayleigh number, Re and dimensionless heat source strength, Ns. It is found that these two parameters exhibit a dual effect on the onset of natural convection; a result noticed in contrast to their effects when they are acting in isolation. © 2007 Elsevier Ltd.

A rare presentation of deep infiltrating cervical endometriosis mimicking cervical cancer

Though endometriosis is a common progressive benign disorder of women, endometriosis of the cervix is rarely seen. It poses a challenge both for diagnosis and management. Most of the patients with Cervical endometriosis are asymptomatic, present with abnormal vaginal bleeding, post-coital bleeding or intermenstrual bleeding. In this paper, we report a rare case of deep infiltrating cervical endometriosis involving the ureter mimicking cervical cancer, the need for awareness to include cervical endometriosis as a differential diagnosis in case of menstural irregularities and its potential to cause serious complications
