Pulmonary Hydatid without Liver Involvement: A Case Series

Pulmonary hydatid is not a rare disease. But raising a suspicion for its diagnosis is limited. There are limited approaches for the diagnosis and treatment of the same. We present here four cases of pulmonary hydatid, without liver involvement, with emphasis on how it was misdiagnosed and received multiple treatment and landed into complications. Most of our cases presented with cough, sputum and hemoptysis. For these nonspecific signs and symptoms, patient is generally treated on a different line of diagnosis. Two of the cases were already treated for abscess and fungal infection. One of the patients was on antitubercular treatment. One of our cases was secondarily infected with aspergilloma. One of the cases was referred to oncologist to start chemotherapy. Interestingly, to raise a suspicion, none of our cases had liver involvement. A detailed history revealed expectoration of white salty material in sputum, living with sheep and dog and expectorating grape-like vesicles in sputum. History helped us to put hydatid as one of our differentials. Echinococcal serology was positive in three cases. Only three cases had on-table appearance of hydatid cyst. All four cases underwent surgical management for complete cure. There is need for strong suspicion and a detailed history and proper set of investigations help in timely diagnosis and management of pulmonary hydatid disease.

Spermine induced protection of onion seed vigour and viability during accelerated ageing

Aim: The aim of the present study was to investigate the role of spermine, a polyamine as a protective agent on accelerated ageing of onion seeds. Methodology: Onion seeds variety Pusa Riddhi was primed with six concentrations of spermine (0.10 mM to 1.25 mM) and also with hydration and halopriming (2% K2HPO4). Hydrated, haloprimed and un-primed seeds were used as control. The primed and control seeds were accelerated aged at 45 oC and 100 % RH for 72 hr. Seed quality was assessed in control, freshly primed seeds, and in primed seeds subjected to accelerate ageing. Results: All priming treatments enhanced the seed quality, there was 2.34–20.33 % increase in germination. Seed priming with 2% K2HPO4 had highest seed quality improvement which was at par with 1.25 mM spermine primed seeds. Enhanced seed vigour and the activity of antioxidant enzymes over un-primed seeds was observed in both 2% K2HPO4 and spermine primed seeds over unprimed seds. Seeds primed with 1.25 mM spermine recorded 66.66 % and 650 % increase in the activity of ROS scavenging enzymes SOD and POD respectively, but they were at par with halopriming. After accelerated ageing, deterioration in seed quality was minimal in seeds primed with spermine. Seeds primed with 1.25 mM spermine recorded 21.33% higher germination, 62.10 % higher speed of germination, 26.56 % longer seedlings, 13.68 % heavier seedlings and 175 % and 200 % higher SOD and POD activity as comparised to un-primed seeds. Seeds primed with 1.25 mM spermine also performed better over halopriming and hydropriming treatments. Interpretation: Onion seed priming with 1.25 mM spermine was most effective treatment in enhancing the seed germination and vigour under accelerated ageing conditions.

Oxidative Stress is Independent Factor for End-stage Renal Disease in Type 2 Diabetes Mellitus Patients

An imbalance between oxidant and antioxidants is thought to precede the development of renal lesions. The aim of present study is to determine the relationship between oxidative markers and severity of microalbuminuria in patients with type 2 diabetes mellitus (T2DM). Atotal of 100 T2DM patients (50 males and 50 females) participated in this study. They were screened for microalbuminuria along with oxidative status in patients. Microalbuminuria was detected by measuring the albumin to creatinine ratio (ACR) in urine samples. Patients were divided into two groups; normoalbuminuria (n=36) and microalbuminuria (n=64) as per the ACR levels. No difference in the groups was observed in terms of age, sex, glycated hemoglobin (HbA1c) and blood pressure. The level of oxidative stress was significantly higher in microalbuminuria group of T2DM patients. A significant correlation was observed between ACR and lipid peroxidation (MDA) levels. We conclude that oxidative stress is one of the important mediators of end-stage renal disease (ESRD).
