Background: Transcription factor 7-like 2 ( TCF7L2 ) gene has a significant role in hyperglycemia in pregnancy (HIP) risk. The current study was planned with the aim to evaluate the association of single nucleotide polymorphism (SNP) rs7903146 in patients of newly detected HIP among Indian population of northern region. Methods: This study was an observational case control study done among newly detected HIP (The World Health Organization (WHO) criteria, 2013) and healthy pregnant females without diabetes. Participants from both the group were genotyped for rs7903146 (C/T) variant of TCF7L2 gene using polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) technique. Results: A total of 71 cases of newly detected HIP were included in the study, out of which 25 (35.2%) of them were of first-time detected diabetes mellitus in pregnancy (DIP) and 46 (64.7%) were of gestational diabetes (GDM) and 100 were pregnant females without diabetes in third trimester were enrolled as controls. Average age of participants in the case group was 28.7 ± 4.0 years and the control group were 26.5 ± 3.6 years ( P value 0.09). The wild homozygous CC genotype, heterozygous CT genotype and homozygous TT genotype were present in 39.4%, 53.5%, 7.1% of case group vs 53%, 43% and 4% of control group, respectively. No significant association of rs7903146(C/T) SNP of TCF7L2 gene in HIP (CC/CT, CC/TT P value 0.15, 0.38, respectively) in our population was found. There was no significant difference in the distribution of genotypes between DIP and GDM. Conclusion: This study shows no evidence of association of rs7903146(C/T) SNP of TCF7L2 gene with newly detected HIP in our population.

Purpose In this report we discuss an individually customized surface mold applicator technique to treat a case of early carcinoma penis. This case report is one of its kind which describes the brachytherapy treatment planning based on orthogonal X-ray technique. Material and methods T1N0 disease with squamous cell carcinoma histology involving the foreskin of penis and abutting the glans penis was treated by surface mold applicator technique. Impression of the organ was taken using alginate. Cast was prepared from the impression using Type 4 gypsum. The acrylic mold-based applicator was fabricated on the cast. The catheters were positioned and fixed on the acrylic mold. The organ is placed in the mold-based applicator and the catheters are reconstructed on two-dimensional imaging. The brachytherapy is delivered by the 18-channel high-dose rate Oncentra brachytherapy using Ir192 source. The dose given was 45 Gy in 15 fractions, twice daily more than 6 hours apart. Results Patient was reviewed after 6 weeks for follow-up and there was complete regression of the ulcer. At present, patient is on follow-up for the last 10 months and is now disease-free. Conclusion With judicious patient selection, surface mold brachytherapy is an attractive alternative to the interstitial brachytherapy. It is comfortable for the patient, is easily repeatable, and is time saving in high work load and limited resource settings. Early results with this technique are promising.
