Lichen sclerosus of soft palate: A rare case report.

Lichen sclerosus (LS) is a rare disease affecting the skin and the mucous membrane, and it is chronic inflammatory in nature. It occurs in both males and females, but mainly affects females in the fifth or sixth decade of life. It mainly involves the genital and perianal areas but can affect any part of the body and the involvement of the oral mucosa is exceptionally rare, but sometimes it affects only the oral mucosa. It requires differentiating from other lesions of the oral cavity which looks similar to this lesion. In considering the rarity of the reported cases, the present article reports one more case of LS affecting the soft palate in an edentulous 66 year‑old male patient.

Distribution of CC-chemokine receptor-5-32 allele among the tribal and caste population of Vidarbha region of Maharashtra state.

BACKGROUND: Genetic relationships among the ethnic groups are not uniform across the geographical region. Considering this assumption, we analyzed the frequency of the CC-chemokine receptor-5 (CCR5)-32 allele of the CCR5 chemokine receptor, which is considered a Caucasian marker, in Bhil tribal and Brahmin caste sample sets from the population. MATERIALS AND METHODS: 108 blood samples were collected from 6 tribe's populations and a caste population from the district of Vidarbha region. RESULTS AND DISCUSSION: The presence of low frequencies of CCR5-Δ32 in an individual of Bhil tribe (0.034, χ2 value 0.017) in the present study implies that these communities may have a better resistance toward human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) than the other studied tribe sample, as non-show such mutation. CONCLUSION: The marginal presence of the allele seen in the studied tribal population could be due to gene flow from the people of European descent. However, lack of the homozygous CCR5-Δ32 mutation and the low prevalence of heterozygous CCR5-Δ32 mutations suggest that the Indians are highly susceptible to HIV/AIDS, and this correlates with the highest number of HIV/AIDS infected individuals in India.

Pars plana vitrectomy with posterior iris claw implantation for posteriorly dislocated nucleus and intraocular lens.

We evaluated the safety and efficacy of pars plana vitrectomy (PPV) with primary posterior iris claw intraocular lens (IOL) implantation in cases of posterior dislocation of nucleus and IOL without capsular support. This was a retrospective interventional case series. Fifteen eyes underwent PPV with primary posterior iris claw IOL implantation performed by a single vitreoretinal surgeon. The main outcome measures were changes in best corrected visual acuity and anterior and posterior segment complications. A total of 15 eyes were included in this study. Eight had nucleus drop, three had IOL drop during cataract surgery and four had traumatic posterior dislocation of lens. The final postoperative best corrected visual acuity was 20/60 or better in 11 patients. This procedure is a viable option in achieving good functional visual acuity in eyes without capsular support.
