Investigations conducted on the identification of predatory spider fauna in maize ecosystem throughout the crop growth, in Tamil Nadu Agricultural University, Coimbatore during 2013-2014 yielded around 2821 spiders, belonging to 16 species under 10 genera of 6 families from seedling to maturity stage. Majority of the spiders collected belonged to the families Lycosidae (1671 individuals), Salticidae (459 individuals), Oxyopidae (352 individuals), Gnaphosidae (178 individuals), Corinnidae (96 individuals) and Clubionidae (65 individuals). The predatory spider species dominating in the maize ecosystem included the species Lycosa barnesi, L. pseudoannulata, Pardosa birmanica, Salticus sp. and Hippasa lycosina. Dendrogram analysis of spiders revealed that the families, Clubionidae and Gnaphosidae were closely related when compared to other predatory spider families. Correlation analysis with the weather parameters showed that the predatory spider population had non-significant positive correlation with relative humidity at 14:22 hrs and negative correlation with all other weather parameters viz., maximum temperature, minimum temperature, relative humidity at 07:22 hrs, rainfall, sunshine hours and rainy days.

Although IGM is considered to be autoimmune in aetiology, however other infectious aetiologies causing granulomatous mastitis and malignancy have to be ruled out by histopathology. In the event of relapse immunosuppression may be required.

Identification rates of ARM nodes can be improved by injecting the blue dye in the upper medial aspect of the arm at the time of induction. Majority of the arm nodes lie between the axillary vein and the first intercostobrachial nerve. It is difficult to preserve the ARM nodes in patients of LABC, who have had good response to NACT and in patients of LABC with poor response to NACT, the incidence of metastasis in ARM nodes is quite high. Therefore, ARM is not a feasible option in patients with locally advanced breast cancer.

This case illustrates the potential benefit of utilizing autologous ALT perforator flap in a girl with Poland's syndrome with a deformed chest wall with hypoplasia of pectoral muscles and absence of the anterior axillary fold which makes positioning of an implant difficult. Breast reconstruction using a microvasular perforator flap is an alternative method to restore the contour of the chest and breast without the use of an implant.
