Rehabilitation of Exenterated Right Eye: A Prosthetic Challenge

Background: Facial defects can be acquired or congenital, but irrespective of etiology, any maxillofacial structure if damaged or missing will result in an unaesthetic and unappealing personality of individual. Orbital defects are very evident and effect the appearance and social front of the individual. Many modalities are available to rehabilitate the defect of an orbit but prosthetic rehabilitation with silicone prosthesis is a simple and effective approach. Retention is generally achieved by engaging available undercuts or using mechanical accessories or skin adhesives etc. This case report describes successful rehabilitation of right orbital defect using a non-surgical approach with room temperature vulcanized silicone and skin adhesives. Case Report: A 45 yr old male reported with, chief complaint of missing right orbit and unaesthetic appearance secondary to gunshot wound. Patient was not ready for any more surgical procedures or additional accessories and available retentive undercuts were minimal. Hence, conventional silicone prosthesis was made using stock eye shell and room temperature vulcanized silicone retained with skin adhesives. The approach was simple to a complex problem and gave reliable result in very limited time. Conclusion: With extensive orbital defect, rehabilitation is difficult and complex as retention is compromised and it is difficult to match the shade of the prosthesis.This case represents a simple and predictable approach to a case of exenterated right orbit with conventional roomtemperature vulcanized silicone and silicone skin adhesives.

Hospital-based Surveillance of Invasive Pneumococcal Disease and Pneumonia in South Bangalore, India.

Objective: To estimate the incidence of invasive pneumococcal disease and pneumonia, distribution of pneumococcal serotypes, and antibiotic susceptibility in children aged 28 days to <60 months. Design: Hospital-based surveillance. Setting:; South Bangalore, India. Participants: 9950 children aged 28 days to <60 months with clinical suspicion of invasive pneumococcal disease or pneumonia. Results: The estimated at-risk population included 224,966 children <5 years of age. Forty cases of invasive pneumococcal disease were identified. Estimated invasive pneumococcal disease incidence was 17.8/100,000 with incidence being highest among children aged 6 months to <12 months (49.9/100,000). Clinical pneumonia syndrome was the most frequent diagnosis (12.5/100,000). Pneumococcal serotypes included: 6A (n=6, 16.7%); 14 (n=5, 13.9%); 5 (n=4, 11.1%); 6B (n=4, 11.1%); 1, 18C, and 19A (n=3 each, 8.3%); 9V (n=2, 5.6%); and 3, 4, 10C, 18A, 18F, and 19F (n=1 each, 2.8%). Serotypes 6A, 14, 6B, 1, 18C, 19A, 9V, 4, 10C, and 18A showed antibiotic resistance. Clinical pneumonia incidence was 2109/100,000, with incidence being highest among children aged 28 days to <6 months (5033/ 100,000). Chest radiograph-confirmed pneumonia incidence was 1114/100,000, with incidence being highest among children aged 28 days to <6 months (2413/100,000). Conclusion: Invasive pneumococcal disease and pneumonia were found to be common causes of morbidity in young children living in South Bangalore, India.

A novel assay method for calcium calmodulin dependent phosphatase from bovine brain extract.

Calcium calmodulin dependent protein ser/thr phosphatase, also referred to as protein phosphatase 2B (PP2B), is rich in neural tissue, and plays an important role in the overall function of the nervous system. Routinely phosphatase assay employs, para-Nitrophenlylphosphate (p-NPP), as a substrate, is also extended to assay PP2B. However, in the present study, the differential spectral characterstic property of tyrosine and phopshotyrosine has been exploited to employ the latter as a candidate substrate for the PP2B assay. The specific activity of PP2B using phosphortyrosine in bovine Bos Taurus indicus brain extract (Bos Taurus indicus), was measured in presence of different metal ions like Ca2+, Mn2+ and Mg2+. Further modulators like dithiothreitol (DTT), calmodulin (CaM) and metal chelators such as EGTA and EDTA were applied to confirm the role of divalent cations and to determine calcium calmodulin dependent phoshphatase activity. PP2B activity was higher with phosphotyrosine in presence of Ca2+ than with p-NPP. Further experiments, involving calmodulin as a modulator, confirmed phosphotyrosine as a better substrate over p-NPP. Calmodulin further enhanced the effect of phosphotyrosine as a potential substrate confirming calcium calmodulin dependent phosphatase activity. Phosphotyrosine is proposed as a better substrate in assaying calcium dependent phosphatase activity when compared to para-nitrophenylphosphate.

Unusual lung mass: benign or malignant?

Primary adenoid cystic carcinoma of lung is a rare tumour. It is a slowly growing, indolent tumour. Average time that elapses before diagnosis is reported to be two years. We report the case of a patient who remained well inspite of harbouring primary adenoid cystic carcinoma of lung for 15 years.
