Background & Objectives: Malignant middle cerebral artery (MCA) stroke constituting 5% of all
strokes carries a high mortality across the world. We aimed to study predictors of malignant MCA
stroke outcome, especially decompressive surgery in a developing country scenario. Methods: This
was a prospective study design where patients with malignant MCA stroke (defined as imaging-CT/
MRI showing infarct involving >2/3rd MCA territory) admitted within 7 days of illness to SCTIMST,
between January 2010 and December 2014 (5 years) were recruited. Clinical and imaging data, surgical
details, in hospital complications and discharge outcome were collected. Follow-up data was collected
at 3 and 12 months post-stroke. Results: We had 74 patients of malignant MCA territory strokes, 42
operated and 32 non-operated, who were comparable at baseline, except for age and stroke severity.
At 3 months, deaths were more among the non-operated group (63% in non-operated vs 23% in
operated group, p=0.02), while functional outcome was comparable. At 1 year follow-up, age below
60 years, lower stroke severity at onset and decompressive surgery were found to be independent
predictors of good outcome. (p=0.04). Delayed surgery group, albeit small had a better 1 year outcome
in comparison to the medical arm.
Conclusions: Early functional outcome in the decompression group did not differ from the medically
treated patients, other than mortality benefit. However, at 1 year, patients with age<60 years, lower
stroke severity and decompressive surgery had a better morbidity and mortality outcome, indicating
long term benefit of this life saving procedure in developing country scenario as well.

Infraglenoid tubercle avulsion fractures are extremely rare injuries. We report a 38-year-old male with glenoid cavity fracture and infraglenoid tubercle avulsion of the left shoulder following a fall from bike. He refused surgery and was treated nonoperatively. Follow-up radiography and CT at 18 months revealed a malunited infraglenoid tubercle with signs of early glenohumeral osteoarthritis. He did not have shoulder instability or pain and had a fair-good functional outcome. There are no previously published data on the anatomic outcome of nonoperatively treated displaced infraglenoid tubercle avulsion fractures based on CT.

OBJECTIVETo assess the correlation between five anthropometric parameters and the distance from tibial tuberosity to medial malleolus in 100 volunteers.
METHODSSix anthropometric parameters were measured in 50 male and 50 female medical students using a metallic scale: medial knee joint line to ankle joint line (K-A), medial knee joint line to medial malleolus (K-MM), tibial tuberosity to ankle joint (TT-A), tibial tuberosity to medial malleolus (TT- MM), olecranon to 5th metacarpal head (O-MH) and body height (BH). Nail size predicted based upon TT-MM measurement was chosen as ideal nail size. A constant was derived for each of the six anthropometric parameters which was either added or subtracted to each measurement to derive nail size. A regression equation was applied to BH measurements. Nail sizes calculated were compared with that obtained from TT-MM measurement and accuracy was evaluated. Accuracy of O-MH and BH regression equations recommended by other authors were calculated in our data.
RESULTSAdding 11 mm to TT-A distance had highest accuracy (81%) and correlation (0.966) in predicting nails correctly. Subtracting 33 mm from K-MM measurement and 25 mm from K-A distance derived accurate sizes in 69% and 76% respectively. Adding 6 mm to O-MH distance had a poor accuracy of 51%. Nail size prediction based upon body height regression equation derived correct nail sizes in only 34% of the cases. Regression equation analysis by other authors based on O-MH and BH distances yielded correct sizes in 11% and 5% of the cases respectively.
CONCLUSIONTT-A, K-A and K-MM measurements can be used simultaneously to increase accuracy of nail size prediction. This method would be helpful in determining nail size preoperatively especially when one anatomic landmark is difficult to palpate.

Characterization and in vitro inhibition studies of protease inhibitor from the mushroom Pleurotus floridanus (PfTI) towards the pest Papilio demoleus is studied. The addition of 1 mM Mn2+ , Na2+ , Ba2+ and Ni2+ enhanced the PfTI activity. The ICP-atomic emission spectrum showed the presence of Ca2+ , Mg 2+ and Zn 2+ in the PfTI. Surfactants SDS and CTAB at a concentration of 1% reduced the PfTI activity whereas, the nonionic detergents Triton X and Tween 80 increased the activity. The inhibitory activity gradually decreased with increase in concentration of DMSO and H2 O 2 . The activity was increased by dithiothreitol up to a concentration of 80 µM and inactivated at 140 µM. The activity of PMSF modified PfTI was drastically reduced to 0.234 U/mL at 4 mM concentration and similar results were obtained for modification of cysteine by N-Ethylmaleimide at slightly higher concentrations. The complex of trypsin and PfTI showed complete loss in fluorescence intensity at 343 nm compared with control. In vitro inhibition studies of PfTI with midgut proteases isolated from citrus pest P. demoleus with protease activity of 1.236 U was decreased to 0.613 U by 50 µL (0.1 mg/mL) of the inhibitor. Inhibitor was stable up to 0.04 M concentration of HCl.
