Objectives: To correlate clinical and radiologic findings, to determine whether brain tomography affects management and routinely indicated in uncomplicated postpartum eclampsia and to differentiate it from other potentially treatable conditions. Methodology: This was a prospective hospital-based study of 28 postpartum eclamptics with atypical or complicated course. Neuroimaging was done after stabilizing them with standardized eclampsia regimen. The relationship between maternal demographic, clinical and neuroimaging data with the cause for postpartum seizures was statistically analyzed with Yate's Chi-square test and Odds ratio with 95% confidence interval. Results: The eclampsia incidence was 3.64% (326/8944 deliveries). Noneclamptic organic cause for seizures was more in late postpartum eclamptics. Among ten early postpartum eclamptics, 80% had normal neuroimaging, one cerebral edema and one neurocysticercosis. Among 18 late postpartum eclamptics, four had normal neuroimaging, one falcian calcification, one cerebral hypoxia, eight (28.6%) cortical venous thrombosis, three granuloma and one gliosis. Conclusion: Despite many abnormalities seen on imaging studies, some are incidental and transient, without chronic neurologic sequelae. Thus, expensive neuroimaging has limited role in uncomplicated cases with typical clinical course and prompt response to standard therapy. Thus, neuroimaging is indicated in atypical and fatal cases where specific therapy may be required.

Grid integrated photovoltaic (PV) system is capable of maximizing solar energy conversion by minimizing power losses. Conventionally, the grid integrated PV system uses boost or buck-boost DC-DC converters in the DC link for lifting up the PV output. Also, a separate complex circuit is used for active power compensation in the grid end. This paper proposes an advanced DC-DC converter by name Super-Lift Converter (SLC) in the DC link of grid integrated PV system. Unlike the conventional DC-DC converters, the proposed converter lifts up the DC link voltage thrice that of the input voltage. In addition, the proposed SLC is regulated using a PI controlled active front end (AFE) topology, which results in operation of unity power factor at grid end. The suggested system is simulated using MATLAB software. The presented results such as grid end voltage and current, input and output power of SLC and DC link voltage validates the effectiveness of the developed system.

Sigmoid volvulus causing intestinal obstruction in immediate postcesarean period is extremely rare, commonest being adhesions and adynamic ileus. The presenting features of this complication are mistaken for usual postoperative signs and symptoms causing delayed diagnosis. Thus, a case of intestinal obstruction due to sigmoid volvulus in immediate postcesarean period is presented. Detorsion of sigmoid and decompression of bowel was done. Intestines were viable because of early detection and prompt intervention. Therefore, high index of suspicion and prompt surgical interventions are required to minimize maternal morbidity and mortality.
