The camps have been organized for rural cervical cancer screening in the villages of Lucknow which offer valuable platform for the detection of infertility in young women and their cytological examination. The cervical cytology has been studied in the cases of infertility to find out if there is any increase in abnormal cytology and compare them with those obtained in fertile women (controls). Since its inception in May 2013, the camps organized were 186 in number and 5682 women attended these camps. Primary infertility was found in 182 and the secondary infertility in 31 women. The incidence of Squamous intraepithelial lesions of cervix (SIL) was found to be 14.8% in women suffering from primary infertility and 16.1% in the secondary infertility cases and was comparable with SIL rate of 17.4% in the controls. Persistent vaginal infections caused by the poor personal genital hygiene practiced by the rural women may be the reason for a high SIL rate in the fertile women. The SIL rate was seen high in the younger women upto 30 years with pain in lower abdomen and erosion cervix in the primary infertility cases while the high SIL rate was seen in 21-30 years age groups with parity 2 in secondary infertility cases with no SIL seen with symptoms and clinical lesions. Mostly young women upto 30 years of age complained of infertility and showed high SIL rate. These women were referred to the Hospital of Era Medical College, Lucknow for further investigation and treatment. [ABSTRACT FROM AUTHOR]

Objective: Squamous cell carcinoma of oral cavity is one of the most common cancers of Indian subcontinent with the 5-year survival rate of 50% despite the recent advances in the treatment. The aim of the present study was to study cancer stem cell markers CD133 and Oct-4 in oral squamous cell carcinoma (OSCC) patients and their correlation with clinicopathological variables. Materials and Methods: This was a prospective study which included 50 cases of histopathologically proven squamous cell carcinoma of oral cavity. Expression of CD133 and Oct-4 was evaluated by immunohistochemistry (IHC) and their expression was correlated with various clinicopathological and demographic parameters. Results: CD133 expression was seen in 20.6% cases of clinical Stage I-II and in 79.4% of clinical stage of III-IV OSCC patients, the difference being statistically significant with the P = 0.048. There was no statistically significant association between CD133 expression and any other clinicopathological or demographic variable. Oct-4 was expressed only in one case. Conclusions: CD133 expression was significantly seen higher in Stage III-IV tumors, the stem cells may be responsible for the aggressiveness of the OSCCs and these stem cells can be potential prognostic markers and targets for the future targeted therapy.

Background: Wild-type p53 nuclear phosphoproteins are critical cell cycle regulatory tumor-suppressor gene. Genetic mutation of p53 gene is common in several head-neck cancers, usually associated with smoking and human papillomavirus (HPV) infection. In India, instead of HPV, tobacco/pan masala chewing is more commonly associated with oral cancer. Aim: The aim of this study was to investigate p53 codon 72 gene polymorphism and expression of p53 by immunohistochemistry (IHC) in oral lesions as a risk factor for its association with malignancy. Materials and Methods: A total of 41 cases of oral lesions comprising 6 cases of leukoplakia and 35 cases of oral squamous cell carcinoma (OSCC), between 30 and 60 years age and tobacco/pan masala chewers were taken. Molecular analysis of p53 codon 72 gene polymorphism was performed by polymerase chain reaction - restriction fragment length polymorphism for Arg/Arg, Arg/Pro, and Pro/Pro. Tissue expression of p53 was done by IHC. Results: Genotype frequencies of 35 carcinoma cases of p53 Arg/Arg, Arg/Pro, and Pro/Pro were 23%, 57%, and 20%, respectively, and six leukoplakia cases of p53 Arg/Arg and Arg/Pro genotype were 50% and 50%, respectively. By IHC for expression of p53 out of 35 cases of OSCC biopsies, 17 (48.57%) had weak staining, 14 cases (40%) showed evidence of p53 protein staining, and four cases (11.42%) showed negative staining. Among six cases of leukoplakia, 3 (50%) showed weak staining and 3 (50%) showed negative results. Conclusion: The findings of the study indicate that there is no significant association between p53 codon 72 gene polymorphism with OSCC and leukoplakia associated with tobacco/pan masala chewing.

Introduction: MicroRNAs (miRNAs) are short (~22 nucleotides) regulatory RNAs that can modulate gene expression and are aberrantly expressed in many diseases, including cancer. It has been suggested that, the presence of single nucleotide polymorphisms in precursor miRNAs (pre-miRNAs) can alter miRNA processing, expression and binding to target mRNA and represents another type of genetic variability, that can contribute to the susceptibility of human cancers. Aim: The present study investigated the genetic variants in premiRNAs (hsa-miRNA-196a2 rs11614913 C/T, hsa-miRNA-499 rs3746444 T/C and hsa-miRNA-146a rs2910164 G/C) for their role in cervical cancer susceptibility. Materials and Methods: The study comprised 164 controls and 184 patients of cervical cancer. The genotypic frequency of miRNA polymorphisms were determined by using a polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) assay. Logistic regression was used for statistical analysis using SPSS Software version 15.0. Results: Hsa-miRNA-499 rs3746444 T/C polymorphism showed a statistically significant association with considerable risk for cervical cancer at genotypes (CC, p=0.001, OR=4.801) and variant allele (p<0.001, OR=2.307). MiRNA 146a and miRNA 196a2 polymorphisms showed no association with cervical cancer. However, interaction of miRNA polymorphisms with smoking habit showed higher risk of cervical cancer with miRNA 196a2 polymorphism in patients with smoking but no significant modification in the risk of cervical cancer was seen for other polymorphisms. Conclusion: The results of the present study demonstrate that, miRNA 499 T/C polymorphism is significantly associated with genetic susceptibility to cervical cancer and may have a role in its pathogenesis.

Intraoral epidermoid cyst of buccal mucosa is generally an uncommon entity. Epidermal inclusion cyst refers sequestration of epidermal elements into the dermal and deeper tissue during the fetal period in line of fusion of embryonic process or acquired due to implantation of the epithelium due to trauma or surgery. It usually presents as slow growing asymptomatic cysts but may be symptomatic due to large size, interfering with mastication and speech or secondary infection. Surgical excision is done for removal of these cysts. We report an interesting case of multiple epidermal cysts in both sides of buccal mucosa in a 35-year-old male patient. [ABSTRACT FROM AUTHOR]

Cervical carcinoma is one of the most common and dreaded diseases of women, and in India, it accounts for 16 per cent of total cervical cancer cases occurring globally. The situation is more alarming in the rural areas where the majority of women are illiterate and ignorant about the hazards of cervical cancer. Different screening strategies such as rural cancer registries and camp approach for cancer detection have been found useful in minimizing the problem of cervical cancer in the villages. Various screening techniques such as visual inspection with acetic acid, visual inspection with Lugol's iodine, visual inspection with magnification devices-magnavisualizer, Pap smear and HPV-DNA testing have been suggested and tried under low-resource settings of our country, and cervical cytology screening has been found effective in reducing incidence of the disease. In the present review, feasibility of different screening methods has been assessed to find out the most suitable mode applicable at the rural level. Single lifetime screening particularly of high-risk women along with analysis of cost-effective tumour markers such as Argyrophilic nucleolar organizer regions (AgNOR) counts to discriminate high-risk dysplasia cases appears to be an appropriate approach in fighting against cervical cancer., Competing Interests: None

Background: In the life of a woman, after 40 years of age, onset of menopause occurs during which hormonal imbalances take place. The present study is aimed at finding out cytopathological changes in the cervical epithelium associated with this hormonal disturbance., Materials and Methods: Cervical cancer screening program is in progress under auspices of Era's Lucknow Medical College and Hospital, Lucknow, since May 2013, in the villages of Lucknow West through camp approach. Till September 2017, 140 camps have been organized and 2440 women attending the camp have been cytologically examined. Out of these, 1534 women were perimenopausal, 165 premenopausal, and 441 postmenopausal. The cytopathological changes have been studied in these three categories of women in relation to different predisposing factors to the cervical carcinogenesis., Results: The squamous intraepithelial lesion (SIL) rate was higher with onset of menopause in the premenopausal women. The SIL rate was higher with nulliparity in these women as well as in the postmenopausal women and also with different gynecological symptoms and clinical lesions of the cervix. The SIL changes associated with HPV and HSV were also higher in them., Conclusion: A high SIL rate found with onset of menopause may be the outcome of gradual estrogen withdrawal in the premenopausal women. Hence, cytological evaluation is mandatory in women between 41 and 45 years of age to rule out any occurrence of cervical cytopathology., Competing Interests: There are no conflicts of interest.

Background: This study determine oxidative stress and survival prospectively in advanced stage non small cell lung cancer (NSCLC) patients following cisplatin based combination chemotherapy., Materials and Methods: The oxidative stress levels (LPO, NO, GSH and SOD) of 144 control subjects and 203 advanced stage (IIIA/IIIB/IV) newly diagnosed NSCLC patients were assessed at pre-treatment (day '0'), and after the 3rd and 6th cycles of chemotherapy. Groups were compared by repeated measures ANOVA while comparison of survival curves was conduced by Kaplan-Meier methods., Results: The pre-treatment mean levels of LPO and NO in patients were significantly (P<0.01) higher while GSH and SOD were significantly (P<0.01) lower as compared to control. The oxidative stress was elevated more significantly (P<0.01) after the chemotherapy and was more evident in higher stage than lower stage patients. The two year overall survival (%) of stage IV patients was significantly lower (P<0.05) as compared to stage III A and III B. The proportional mortality was also maximal in stage IV patients (37.0%) followed by stage III B (31.7%) and III A (20.0%)., Conclusion: Cisplatin based combination chemotherapy induces oxidative stress in NSCLC patients.
