Recurrent Giant Cell Tumour of Maxilla: A case report and review of literature.

Giant cell tumors (GCTs) are rare, locally aggressive neoplasms that commonly affect the long bones. However, GCTs can also occur in the craniofacial region, including the maxilla. This case report presents a rare case of recurrent giant cell tumor of the maxilla in a 32-year-old male patient. The patient underwent a total maxillectomy with clear margins, which resulted in successful local control. This report highlights the clinical presentation, diagnostic approach, treatment modalities, and favorable prognosis associated with recurrent giant cell tumors of the maxilla.

A Study of the Impact and Restitutive Efforts of Cervical Cancer Screening during the COVID-19 Pandemic in a Regionsl Cancer Centre in Eastern India.

AIM: To evaluate the feasibility and efficacy of switching to a self-sampling based screening as compared to ongoing provider-collection based screening using HPV DNA test and assess the compliance of HPV positive women for further treatment during the COVID 19 pandemic. METHOD: The study participants were women aged 30-60 years from rural and semi-urban communities around Kolkata, who underwent screening followed by HPV testing by Hybrid Capture II test. In the pre pandemic era, the women who attended the health centres where trained health workers that collected cervical samples. Following lockdown, the health workers distributed the self-sampling device to the women during home visits and counselled them to collect their samples by themselves. Thereafter the self collected screened positive women were brought to the hospital for further treatment instead of community clinics. RESULTS: From April 2018 to March 2020, 12,718 women underwent screening using either HPV DNA test or visual inspection with acetic acid. HPV samples were either provider collected (62.7%) or self-collected (37.2%). The HPV positivity and CIN2+ detection rate were 5.4% and 2%. From April 2020 to February 2022, 10,792 women underwent screening using self-sampling only. The HPV positivity rate and CIN2+ detection rate were found to be 5.1% and 1.9 % . CONCLUSION: Cervical cancer screening by HPV self-sampling advocates participation of more women especially in rural areas, while accelerating progress towards elimination of cervical cancer.

Comparative Study of the Crestal vs Subcrestal Placement of Dental Implants via Radiographic and Clinical Evaluation.

AIM: The study aims at using the level/depth of implant placement (equicrestal or cretsal) as the key parameter in measuring the vertical crestal bone loss (CBL) mesially and distally, using periapical radiographs (IOPARs) taken at 1-, 3-, and 6-months interval, postprosthetic loading. MATERIALS AND METHODS: Patients (n = 40; 18-65 years), with edentulous space anteriorly or posteriorly, were randomly divided into two groups, namely, group I (equicrestal) and group II (subcrestal) with 20 patients in each group. Implants were placed at an edentulous site (delayed implants), after obtaining cone-beam computed tomography (CBCT) scans. Prosthetic loading (following osseointegration) was done within 3 months of implant placement. The patients were followed up and IOPAR were taken to measure CBL at 1-, 3-, and 6-months interval, postloading. The CBL between the two groups was compared using IOPARs. The data obtained was compiled and unpaired Student's t-test was done for statistical analysis. RESULTS: After the statistical analysis of the data obtained during follow-up, CBL was measured radiographically. Mesial and distal vertical bone loss was charted and compared between the two groups. The mean bone loss on the mesial aspect for group I implants is 0.39 mm and for group II implants, it is 0.27 mm, 6 months postloading, determined radiographically. CONCLUSION: Subcrestally placed implants are conducive to the overall oral rehabilitation, as it has been seen to preserve marginal peri-implant bone for longer durations than their equicrestally placed counterparts, within the limitations of the current study. CLINICAL SIGNIFICANCE: The study prospectively relates the level of implant shoulder with respect to alveolar crestal bone, postloading. Following radiographic comparison between the two groups, significant clinical findings indicated that better esthetics and stability were seen in the subcrestally placed implants. This proves that implant placement level directly influences crestal bone levels; hence, indirectly affects esthetics and function.

Evaluation of numerical rating scale and neuropathic pain symptom inventory pain scores in advanced ovarian carcinoma patients undergoing surgery and first-line chemotherapy.

BACKGROUND AND AIM: Advanced epithelial ovarian cancer (OC) has a high disease manifestation with difficult-to-manage symptoms that limit the patients' functionality. Abdominal pain, persistent back pain, and neuropathic pain are among the common discomforts associated with OC and its treatment. Our study aims to determine pain scores in advanced OC patients undergoing surgery and chemotherapeutic treatment with carboplatin and paclitaxel. METHODS: One hundred and ten patients with advanced epithelial OC were enrolled and treated with surgery and an adjuvant/neoadjuvant chemotherapy regimen of carboplatin-paclitaxel for six cycles (triweekly). Pain intensity was analyzed using the validated numerical rating scale for resting, movement, sleep interference-associated pain, and neuropathic pain scores were evaluated using the neuropathic pain symptom inventory scale. Pain was correlated with Qol according to Fact-O questionnaires. Chemo-response was evaluated using the CA125 blood biomarker and CT scan of the abdomen and thorax. Data were recorded at baseline, 2, 4, and 6 months of the six chemotherapy cycles. RESULTS: Of the 110 patients, no statistically significant differences were found in pain at baseline and after treatment (P > 0.05) and between the responder and non-responder categories (P > 0.05). However, movement-associated pain had a significant correlation with chemo-response and a strong positive correlation with the patients' physical and functional wellbeing. There were more chemo-induced neuropathy occurrences (P = 0.001) in the neoadjuvant chemotherapy group. CONCLUSION: Patients in the neoadjuvant chemotherapy arm experienced more chemo-induced neuropathy that was persistent and did not improve with the treatment. RELEVANCE FOR PATIENTS: Peripheral neuropathy is a common adverse effect of platinum and taxane chemotherapeutic drugs that persists throughout cancer treatment and in survivorship. This research provides evidence that chemotherapy-associated neuropathy affects Qol of patients and it will be helpful to improve pain and palliative care management policies.

Assessment of quality of life among advanced ovarian cancer patients in a tertiary care hospital in India.

PURPOSE: The study aims to record the quality of life (Qol) and its changes while ovarian cancer (OC) patients undergo debulking surgeries and chemotherapy in a tertiary care hospital of Eastern India. METHODS: Patients with advanced epithelial OC (FIGO stages III-IV) were recruited. They underwent primary/interval debulking surgeries with classical chemotherapy (adjuvant/neoadjuvant) of intravenous tri-weekly doses of paclitaxel + carboplatin. QoL was assessed using Fact- O + FACIT-Sp-12 questionnaire with a set of 51 questions in different domains (spiritual, physical, social, emotional, and functional factors) and a special set for OC patients under the heading "Additional concerns." The responses from patients were recorded at baseline (diagnosis/study entry), 2, 4, and 6 months during the treatment visits. Overall survival (OS) was assessed using Kaplan Meier curve. RESULTS: A majority of patients were 49.15±10.8 years of age, school-educated (54%), unemployed/homemakers (73.5%), belonging from rural setup (64.6%) with a monthly income of Rs. 2000/- to Rs. 5000/-. There was no statistically significant (p>0.05) improvement found in Qol from the baseline till the end of the study, neither overall nor in subsets (responders (Rs)/partial responders (PRs)/non-responder (NRs) groups or the adjuvant and neoadjuvant chemotherapy groups). The common toxicities like anemia, constipation, and weight loss were significantly (p<0.05) correlated with the patients' physical, functional, emotional, and social well-being. CONCLUSION: Ovarian cancer patients represent a poor functional, social, and disease-specific quality of life that needs to be addressed, identified, and improved by the growing nexus of healthcare providers and researchers.

Experience of Human Papillomavirus Vaccination Project in a Community Set Up-An Indian Study.

BACKGROUND: Initial introduction of HPV vaccination from 2006 to 2008 was largely confined to high-income countries (HIC), such as Australia, the United States, and Europe, where cervical cancer incidence is lowest. Much of the post-introduction literature has come from HICs, with a focus on coverage levels achieved, provider acceptability and early impact of vaccination on disease endpoints. However, there are a few literature evaluating the mechanics of delivery, feasibility of the health system and acceptability from low and middle income countries (LMICs). The primary objective was to evaluate the feasibility, acceptability and safety of two dose HPV vaccination in adolescent girls between 9-14 years. METHODS: After an orientation camp followed by filling up of prevaccine questionnaires by parents on HPV related diseases and its vaccines and informed consent, girls between9-14years were vaccinated. They were asked to report any side effects in the next 24 hours after each dose. Parents were contacted on Day 7 and Day 30 to enquire about any side effects . Total 3 visits were required i.e two for the vaccination and one visit at 7th month post completion of second dose. To estimate the acceptability, successful completion of two doses by at least 80% of the girls were measured. For measurement of acceptability, either of the parents were recalled along with their daughter at 7th month and were asked to fill up a pre-set questionnaire. RESULTS: After institutional ethical clearance, 555 girls were recruited in the study from rural parts of West Bengal, India between July, 2017 to November, 2017. Out of which, 544 girls (98%) received their 2nd dose between January, 2018 and May, 2018 without any serious adverse effects. No serious adverse effect was reported on follow up till December, 2019. CONCLUSION: The introduction of HPV vaccination is feasible in large scale and the vaccine is well accepted and safe.

Sinonasal IgG4-related disease: a rare and emerging entity broadening the differential diagnosis in the sinonasal universe.

BACKGROUND: IgG4-related disease (IgG4-RD) is a multi-organ immune-mediated disorder characterized by fibroinflammatory mass-forming lesions, mimicking malignancy or infection. While well-documented in salivary glands, orbit and thyroid in the head and neck, sinonasal IgG4-RD is rare. METHODS: Cases of sinonasal IgG4-RD were retrieved, and clinicopathological features reviewed. RESULTS: Seven cases of sinonasal IgG4-RD were identified over a 2-year period, including three males and four females, with an age range of 13-48 years (median: 32 years). Patients presented with cheek swelling, pain and visual disturbances. Serum IgG4 levels were mildly elevated. Storiform fibrosis, obliterative phlebitis and plasma cell infiltration were seen in varying proportions. Destruction of bone and subepithelial mucoserous glands was present. ALK-1 negativity distinguished from inflammatory myofibroblastic tumor. CONCLUSION: Sinonasal IgG4-RD expands the growing spectrum of IgG4-RD. A high degree of suspicion is required to include IgG4-RD in differential diagnosis of sinonasal masses, and perform detailed histological and immunohistochemical workup for accurate diagnosis.

Glutathione S-transferasesP1 AA (105Ile) allele increases oral cancer risk, interacts strongly with c-Jun Kinase and weakly detoxifies areca-nut metabolites.

The Glutathione S-transferases (GSTs) protects cellular DNA against oxidative damage. The role of GSTP1 polymorphism (A313G; Ile105Val) as a susceptibility factor in oral cancer was evaluated in a hospital-based case-control study in North-East India, because the habit of chewing raw areca-nut (RAN) with/without tobacco is common in this region. Genetic polymorphism was investigated by genotyping 445 cases and 444 controls. Individuals with the GSTP1 AA-genotype showed association with the oral cancer (OR = 3.1, 95% CI = 2.4-4.2, p = 0.0002). Even after adjusting for age, sex and habit the AA-genotype is found to be significantly associated with oral cancer (OR = 2.4, 95% CI = 1.7-3.2, p = 0.0001). A protein-protein docking analysis demonstrated that in the GG-genotype the binding geometry between c-Jun Kinase and GSTP1 was disrupted. It was validated by immunohistochemistry in human samples, showing lower c-Jun-phosphorylation and down-regulation of pro-apoptotic genes in normal oral epithelial cells with the AA-genotype. In silico docking revealed that AA-genotype weakly detoxifies the RAN/tobacco metabolites. In addition, experiments revealed a higher level of 8-Oxo-2'-deoxyguanosine induction in tumor samples with the AA-genotype. Thus, habit of using RAN/tobacco and GSTP1 AA-genotype together play a significant role in predisposition to oral cancer risk by showing higher DNA-lesions and lower c-Jun phosphorylation that may inhibit apoptosis.
