Serous ovarian cancer is the most common malignant ovarian tumour. Traditional management consists
of surgical resection with postoperative chemotherapy. Currently neoadjuvant chemotherapy is offered
to patients with advanced stage disease. The present study aims to analyse the histomorphological
alterations in serous ovarian cancer following neoadjuvant chemotherapy. Correlation of these
morphological alterations with survival is also presented here. Serous ovarian cancers from 100
advanced stage cases were included; 50 were treated with pre-surgery chemotherapy. Semi-quantitative
scoring was used to grade the alterations in tumour morphology. Survival data was correlated with
the final morphological score. Tumour morphology was significantly different in cases treated with
neoadjuvant chemotherapy (CT group) as compared to cases with upfront surgery. The CT group
cases showed more fibrosis, calcification, and infiltration by lymphocytes, plasma cells, foamy
and hemosiderin-laden macrophages. The residual tumour cells had degenerative cytoplasmic
changes with nuclear atypia. Patients with significant morphological response had a longer median
survival, although it did not attain statistical significance in the current study. With the increasing
use of neoadjuvant chemotherapy in management, the pathologist needs to be aware of the altered
morphological appearance of tumour. Further studies are required to establish a grading system to
assess the tissue response which can be helpful in predicting the overall therapeutic outcome and
the prognosis of patients.

OBJECTIVETo investigate the effect of Lead (Pb) acetate exposure on Semliki forest virus (SFV) pathogenesis in mice.
METHODSDifferent doses (62.5, 125, 250 and 500 mg/Kg body weight) of Pb dissolved in normal saline were given to mice by oral intubation in a sub-acute (28 days) and sub-chronic (90 days) regimen followed by SFV infection. Morbidity, mortality, clinical symptoms, mean survival time (MST), changes in body and organ weight, accumulation of lead in soft tissues, virus titre in brain and histopathological alterations were compared between lead exposed and infected groups.
RESULTSEarly appearance of virus symptoms, increased mortality, decreased MST, enhanced SFV titre and greater tissue damage were observed in lead exposed-SFV-infected mice.
CONCLUSIONPre-exposure to lead increases the susceptibility of mice towards SFV infection. Further studies are suggested in view of the persistence of lead in the environment and the possibility of infection by microbial pathogens.

Isolated trochlea fracture in adults is a rare surgical entity as compared to its capitellar counterpart. It has been only mentioned sporadically in the literature as case reports. Fracture of the trochlea is accompanied by other elbow injuries like elbow dislocation, capitellum fracture, ulnar fracture and extraarticular condylar fracture. Here we report a unique case of isolated displaced trochlea fracture associated with fractures of the lateral end clavicle and the distal end radius. We propose a unique mechanism for this rare combination of injuries: typical triad of injury, i.e. fracture of the distal end radius with trochlea and fracture of the lateral end of the clavicle. Nonoperative treatment is recommended for undisplaced humeral trochlea fractures; but for displaced ones, anatomical reduction and internal fixation are essential to maintain the congruous trochlea-coronoid articulation and hence to maintain the intrinsic stability of the elbow.

PURPOSEBoth cannulated cancellous screw (CCS) and sliding hip screw (SHS) are used in femoral neck fracture fixations, but which is superior is yet to be determined. This study was aimed to compare the clinicoradiological outcome of femoral neck fracture treated with SHS or CCS in young adults.
METHODSAdults (16e60 years) with femoral neck fracture were divided into Group 1 fixed with SHS and Group 2 fixed with three CCS after closed reduction. Pain relief, functional recovery and postoperative radiographs at 6 weeks, 3 months, 6 months and then yearly for upto 4 years were analyzed.
RESULTSGroup 1 (n=40) achieved radiological union at mean of 7.6 months, with the union rate of 87.5% (n=35), avascular necrosis (AVN) rate of 7.5% (n=3) and mean Harris Hip Score (HHS) of 86.15 at the end of 4 years. In Group 2 (n=45) these parameters were union at 7.1 months, union rate of 82.22% (n=37), AVN rate of 6.67% (n=3) and HHS of 88.65. Comparative results were statistically insignificant.
CONCLUSIONThere is no significant difference in clinicoradiological outcome between the two implants.
