A retrospective study of 30 cases of mesiodens is presented. male preponderance of 1.5:1. was 64% mesiodens were impacted and 36% erupted. Inverted impacted mesiodens was seen in 62.5% of the impacted mesiodens. 66.6% cases had 2 mesiodens per case. The harmful effects on the dentition were mostly crowding, rotation, diastema and impacted permanent incisor.

A total of 488 blood samples from tribal as well as non-tribal donors of Bihar and West Bengal were analysed for presence of abnormal haemoglobin variants. Out of 488 samples ABO and Rh blood groups were studied in 468 samples. Predominance of group B was noted in both the tribal and non-tribal groups and absence of Rh(d) was noted in non-tribal population with the exception of the tribals where 4.42% Rh(d) gene was found. Incidence of haemoglobin E gene was very low in most cases but relatively higher in non-tribal populations, while the range of raised haemoglobin A2 varied from 5.84% to 8.80%.

A survey of Hepatitis B virus (HBV) carrier state of paid and voluntary blood donors in and around the city of Calcutta has been carried out. HBV carrier state is higher in paid donors (5.84%) than voluntary donors (1.79%). The nutritional status of paid donors as assessed by serum protein, immunoglobulin and cholesterol shows evidence of malnutrition and chronic infection. The socio-economic status of the prospective blood donors has an important bearing on the persistence of carrier state for HBV.
