Recent advances in ocular leprosy.

Proper MDT soon after detection of leprosy and anti-reaction measures with newer steroids, regular supervision and monitoring of those released from treatment (RFT) reduce the incidence of ocular leprosy to a remarkable extent. Today, most eye complications are because of normal ageing process or of other phenomena in normal healthy population. Cataract and lagophthalmos are the main causes of blindness. However, in India, though the rate of cataract surgical coverage is up to the mark, the same for lagophthalmos is lagging far behind. Integration of management of ocular leprosy into community eye health care service is the talk of the day along with other health care facilities delivered to people affected with leprosy (PAL). Routine eye examinations are necessary for all PB and MB patients, as well as for the RFT persons in order to detect and treat eyes that are at high risk. All eye surgeries can be performed when needed, irrespective of deformities and bacteriological status, by latest microsurgical techniques with good outcome, and better rehabilitation measures. Reorientation training in ocular leprosy is the immediate special need for ophthalmologists, paramedical ophthalmic assistants and eye health care managers working in general hospitals in those areas that were previously "leprosy endemic zones".

Influence of temperature on survival, growth and fecundity of the freshwater snail Indoplanorbis exustus (Deshayes)

To note the effect of temperature on survival, growth and fecundity, newly hatched (zero day old) snails Indoplanorbis exustus were cultured at 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees and 35 degreescentigrades constant temperatures and room temperature (17.5 degrees - 32.5 degrees centigrades). Individuals exposed to 10 degrees centigrades died within 3 days while those reared at 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees centigrades and room temperature survived for a period of 6, 27, 18, 16, 12 and 17 weeks respectively. An individual added on an average 0.21 mm and 0.45 mg, 0.35 mm and 7.94 mg, 0.63 mm and 15.5 mg, 0.81 mm and 27.18 mg, 1.07 mm and 41.48 mg and 0.78 mm and 31.2 mg to the shell diameter and body weight respectively at those temperatures per week. The snails cultured at 15 degrees centigrades died prior to attainment of sexual maturity. On an average, an individual produced 31.9 and 582.77, 54.86 and 902.18, 56.01 and 968.45, 49.32 and 798.68 and 62.34 and 1143.97 capsules and eggs respectively at 20 degrees, 25 degrees, 30 degrees, 35 degrees centigrades and room temperature (17.5 degrees - 32.5 degrees centigrades)
