RESUMEN

Post traumatic urethral injury is uncommon in children. The management of this condition is dependent on the severity of injury. Initial suprapubic cystostomy with delayed repair is the conventional treatment. Successful reconstruction of urethral injury may be followed by urethral stricture, incontinence, impotence, and retrograde ejaculation. Successful repair of post traumatic urethral injury followed by secondary incontinence in children has not been well addressed in literature. We report the management of one such child, with satisfactory outcome with implantation of a new model of single piece artificial urinary sphincter in the bulbar urethra by perineal approach.

RESUMEN

The study was carried out to determine the seasonal variation of nitrite levels in drinking and surface waters of urban, peri-urban and rural areas of Lucknow, during 2007-2008, and to evaluate the nitrite removal and accumulation potential of certain native aquatic macrophytes. Most of the drinking and surface water samples were collected from urbanized region of the city. All drinking water samples detected, showed higher nitrite level in winter, when compared with that in summer and rainy seasons. However, in drinking water samples nitrite level was below the permissible limit i.e. 3.29 mg l(-1) NO2. The surface water showed more than 3 fold higher levels of nitrite over the permissible level i.e. 0.06 mg l(-1), and the level was higher during rainy season than in summer and winterseasons. Eight macrophytes viz. Peltandra virginica, Utricularia vulgaris, Eichhomia crassipes, Trapa natans, Mimulus glabratus, Marsilea quadrifolia, Pistia stratiotes and Polygonum persicaria were studied for phytoremediation potential of nitrite from the water under simulated laboratory conditions. The gradual diminution in the level of nitrite in the water and simultaneously it's increase in the plant tissues was recorded at 5th, 10th and 15th d after plant culture. All the plants selected, removed nitrite from water but Polygonum persicaria, Mimulus glabratus, Trapa natans and Pistia stratiotes were found more efficient and removed nitrite upto 60.91, 58.09, 60.97 and 72.28%, respectively. Observations revealed that Pistia stratiotes can be used forthe effective removal of nitrite from the contaminated water.

RESUMEN

Antiphospholipid antibody syndrome (APLAS) characterises a clinical condition of arterial and venous thrombosis associated with phospholipids directed antibodies. APLAS occurs in 2% of the general population. However, one study demonstrated that 7.1% of hospitalised patients were tested positive for at least one of the three anticardiolipin antibody idiotype. Antiphospholipid antibodies often inhibit phospholipids dependent coagulation in vitro and interfere with laboratory testing of hemostasis. Therefore, the management of anticoagulation during cardiopulmonary bypass can be quite challenging in these patients. Here, we present a case of right atrial mass removal and pulmonary thrombectomy in a patient of APLAS.

RESUMEN

Dengue fever (DF) is the most common and widespread arbovirus infection worldwide. It is endemic in the tropical and sub-tropical areas of the world especially in Southeast Asia, the Pacific, East and West Africa, the Caribbean and South America with cyclical epidemics. Major epidemics of DF have occurred in India and Southeast Asia in the last two decades. We have outlined the anaesthetic management of a 64-year-old man with DF who needed urgent Coronary artery Bypass graft surgery.

RESUMEN

Ionically bound peroxidases (POD) were salt extracted from the pulp of four Indian apple varieties, i.e., Golden delicious HP, Golden delicious JK, Red delicious, and Royal delicious. They were precipitated with chilled ethanol. Thermal treatments of partially purified enzymes were given from 40-70 degrees C for 30 minutes. Golden delicious HP peroxidase showed thermostability at 60 degrees C, while three other peroxidases were observed at 50 degrees C. Phenolic compounds (i.e., caffeic acid, ferulic acids, p-coumaric acid, protocatechuic acid) and metal ions (i.e., Cu2+ and Fe2+) activated all apple peroxidases. However, Mn2+ inhibited the peroxidases from Golden delicious HP, Golden delicious JK, and Red delicious, and a substantial increase was observed in Royal delicious peroxidase. Mg2+ inhibited the peroxidases from Golden delicious HP and Red delicious, but marginal activation was reported in peroxidases from Golden delicious JK and Royal delicious. Zn2+ established stimulation in Golden delicious HP and Golden delicious JK peroxidases, but inhibition was observed in peroxidases in Red delicious and Royal delicious.. Methionine, proline, tryptophan, and valine stimulated all four apple peroxidases, but cysteine showed inhibition in Golden delicious JK.

RESUMEN

Although there are many causes of ulcer disease in postoperative period, hypoperfusion during cardiopulmonary bypass and advanced age are two key causes. We came across two cases of peptic ulcer perforation after coronary bypass graft surgery where these two common factors were absent. We have discussed various aetiolofical factors responsible for genesis of gastrointestinal ulcers in patients undergoing cardiac surgery using cardiopulmonary bypass.
