Unilateral pulmonary artery agenesis presenting with unilateral usual interstitial pneumonia in adulthood

Unilateral interstitial lung disease secondary to unilateral pulmonary artery agenesis (UPAA) is a rare anomaly due to a malformation of the sixth aortic arch of the affected side during embryogenesis. While most of the patients present in neonatal period with either cardiac anomalies or respiratory symptoms some of them can remain asymptomatic and late diagnosis is possible when suspicious presentation is noted on chest radiography. We report a case of 32-year female with a history of recurrent respiratory tract infection, who presented with cough and expectoration and the diagnosis of unilateral interstitial lung disease secondary to ipsilateral pulmonary interruption was made

13. MRI diagnosis in Metachromatic leukodystrophy: A case report.

Leukodystrophies encompass a wide spectrum of inherited neurodegenerative disorders affecting white matter of central nervous system. There are distinctive clinical, biochemical, pathologic, and radiologic features of each leukodystrophies. Magnetic resonance imaging is primary imaging modality in the identification of underlying white matter abnormalities, to monitor the progression and the response to therapy. Metachromatic leukodystrophy (MLD) is a rare group of inherited, lysosomal storage disease characterized by intra-lysosomal accumulation of sphingolipid sulfatides due to reduction or complete deficiency of Arylsulfatase-A enzyme necessary for normal myelin sheath formation. Diagnosis is usually suspected on MRI of brain and confirmed by enzyme assays. Hematopoietic stem cell transplantation in infancy has shown to delay the progression of disease, making early diagnosis very imperative. We present a case of 5 years old male child of metachromatic leukodystrophy, presented with regression of milestone and progressive spasticity, who underwent MRI brain and diagnosis was confirmed by enzyme assay

HRCT chest in COVID-19 patients: An initial experience from a private imaging center in western India

The COVID-19 pandemic began in late December in 2019 and has now reached to 216 countries with 1,08,42,028 confirmed cases and 5,21,277 deaths according to the WHO reports and 6,49,666 confirmed cases in india alone with 18,679 deaths (as on 04th july 2020) . RT-PCR has been considered the standard test for diagnosis of COVID 19. However, there has been reported a high false negative rate. This high false negative rate increases the risk of further transmission as well as delays the timely management of suspected cases. We have conducted HRCT chest of various (200 patient case study) proven and suspected cases of COVID-19 infection in the months of April, May and June 2020. Out of 200 scanned patients with clinical complains and suspicion, positive HRCT chest findings were seen in 196 patients, showing clinical-radiological correlation and an accuracy of 98%. The sensitivity of chest CT in suggesting COVID-19 was 98.6% (146/148patients) based on positive RT-PCR results. In patients with negative RT-PCR results and high clinical suspicion, 90% (18/20) had positive chest CT findings. HRCT chest is very sensitive and accurate in picking up lung parenchymal abnormalities in laboratory negative RT-PCR cases with high clinical suspicion of COVID-19 infection and also in all symptomatic patients where RT-PCR was not done. HRCT can also be very sensitive, cost effective and time effective in screening patients with high clinical suspicion. HRCT scores over RT-PCR in giving immediate results, assessing severity of disease and prediction of prognosis. We suggest HRCT chest for detection of early parenchymal abnormalities, assessing severity of disease in all patients with clinical symptoms and suspicion of COVID infection irrespective of laboratory RT-PCR status

Amelioration of Chlorpyrifos-Induced Toxicity in Brassica juncea L. by Combination of 24-Epibrassinolide and Plant-Growth-Promoting Rhizobacteria

Pervasive use of chlorpyrifos (CP), an organophosphorus pesticide, has been proven to be fatal for plant growth, especially at higher concentrations. CP poisoning leads to growth inhibition, chlorosis, browning of roots and lipid and protein degradation, along with membrane dysfunction and nuclear damage. Plants form a linking bridge between the underground and above-ground communities to escape from the unfavourable conditions. Association with beneficial rhizobacteria promotes the growth and development of the plants. Plant hormones are crucial regulators of basically every aspect of plant development. The growing significance of plant hormones in mediating plant–microbe interactions in stress recovery in plants has been extensively highlighted. Hence, the goal of the current study was to investigate the effect of 24-epibrassinolide (EBL) and PGPRs (Pseudomonas aeruginosa (Ma), Burkholderia gladioli (Mb)) on growth and the antioxidative defence system of CP-stressed Brassica juncea L. seedlings. CP toxicity reduced the germination potential, hypocotyl and radicle development and vigour index, which was maximally recuperated after priming with EBL and Mb. CP-exposed seedlings showed higher levels of superoxide anion (O2−), hydrogen peroxide (H2O2), lipid peroxidation and electrolyte leakage (EL) and a lower level of nitric oxide (NO). In-vivo visualisation of CP-stressed seedlings using a light and fluorescent microscope also revealed the increase in O2−, H2O2 and lipid peroxidation, and decreased NO levels. The combination of EBL and PGPRs reduced the reactive oxygen species (ROS) and malondialdehyde (MDA) contents and improved the NO level. In CP-stressed seedlings, increased gene expression of defence enzymes such as superoxide dismutase (SOD), ascorbate peroxidase (APOX), glutathione peroxidase (GPOX), dehydroascorbate reductase (DHAR) and glutathione reductase (GPOX) was seen, with the exception of catalase (CAT) on supplementation with EBL and PGPRs. The activity of nitrate reductase (NR) was likewise shown to increase after treatment with EBL and PGPRs. The results obtained from the present study substantiate sufficient evidence regarding the positive association of EBL and PGPRs in amelioration of CP-induced oxidative stress in Brassica juncea seedlings by strengthening the antioxidative defence machinery
