Early diagnosis of oral cancer through visual inspection followed by histopathological confirmation is a pivotal step for reducing rates of morbidity and mortality. There are several auxiliary devices used to improve oral examination. The purpose of this cross-sectional pilot study is to evaluate the sensitivity and specificity of the Visually Enhance Lesion Scope (VelScope) system when it is used by the general dentist after a yearly oral medicine training. Thirty-five patients with oral lesions were evaluated with clinical and VelScope examination by two general dentists, one of which trained with a specific course. A comparison of the histopathological results, clinical examination, and VelScope made by both dentists was performed through statistical analysis. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for detecting oral potentially malignant disorders (OPMDs) are 53.3%, 65%, 53.3%, 76.5% for unskilled dentist, 73.3%, 65%, 61.1%, 76.5% for skilled clinician. When both examiners use VelScope the values are 53.3%, 70%, 57.1%, 66.7% for unskilled general dentist (u-GD), 86.7%, 90%, 86.7%, 90% for skilled general dentist (s-GD). Improvement of a skilled general dentist for detecting malignancies is higher than inexperienced examiner when using VelScope. VelScope alone is unable to improve the general dentist’s ability to detect malignancies, but it could be a useful adjunctive device for clinicians when a focused training program is performed.

Background: Oral cancer is the third most common cancer in India which is attributed to the high tobacco burden especially due to a myriad of smokeless tobacco (SLT) products available in the market. Gul/Gul manjan is a commercially-produced, tobacco-based dentifrice, indigenous to rural India and Bangladesh, and mainly used by women. It is both highly addictive and carcinogenic; yet its prevalence, reasons for use and association with oral potentially malignant disorders (OPMDs) and oral cancer are scarcely documented in literature, making this study the first of its kind. Aim: To determine the prevalence of Gul use, its predictors and resultant OPMDs and oral cancer in such consumers. Methods: A cross-sectional study was performed among 3452 individuals visiting the Institute's Oral Health Promotion Clinic between December 2016-March 2018. Their basic demographic details, tobacco use history and abnormalities found on oral examination, were documented in the clinical record form. Data pertaining to Gul users was subjected to further statistical analysis. Results: Of the total individuals screened, 2.9% (n=101, P < 0.001) consumed Gul (89.1% current and 10.9% former users), with majority female consumers (86.1%) from peri-urban Noida. It was used (up to 5 times daily) mainly to alleviate dental pain due to caries/endodontic lesions, which were present in 35.6% users ( P = 0.004). A statistically significant positive association was seen between Gul use and development of OPMDs ( P < 0.001) and oral cancer ( P = 0.001), with 7.9% (n=10; 70% Gul alone users) of the overall leukoplakias/preleukoplakias (n=127), and 7.1% (n=1, Gul alone user) of all the oral cancer cases (n=14), found in Gul users. The duration of Gul use ranged up to 25 years, indicating its high dependency. Conclusion: Gul use is relatively uncommon than other SLT products in India, even among males (the major group of tobacco consumers). Apart from teeth cleaning, Gul is a cheap, easily accessible antidote for acute dental pain relief (owing to nicotine-induced analgesia) among rural women who apply it multiple times daily onto the affected teeth and adjacent gum/mucosa, often leading to its dependency. Courtesy its significant carcinogenic potential which has been clearly reported here (OPMDs and oral cancer development among users), combating/preventing its production, easy availability (in spite of the complete ban on tobacco use in dentifrices) and consumption, is essential. Therefore, the public health challenge of prevention of the use of this form of SLT ie tobacco-based dentifrices, warrants greater interest and action than that has been received thus far, which in turn would contribute to the overall mission of oral cancer prevention.

The aim of this work was to evaluate the prevalence of TP53Arg72Pro mutations and their possible relationship with oral carcinoma and oral potentially malignant disorders in Argentine patients. A cross-sectional study was performed on 111 exfoliated cytologies from patients with oral cancer (OC), oral potentially malignant disorders (OPMD) and controls. The TP53Arg72Pro mutations were determined using conventional PCR. We evaluated univariate and multivariate study variables, setting p < 0.05. We found: (a) a low frequency of Pro72 variant in control group and a high frequency in OC and OPMD, as well in OC and oral leukoplakia (OL) diagnosis; (b) multivariate association among the TP53CC genotype and females over 45 years with no tobacco nor alcohol habits with oral lichen planus pathology; (c) multivariate association between the TP53GC genotype and males with alcohol and tobacco habits and OC and OL pathologies. Our results showed that the wild-type Arg72variant was related to control patients and Pro72variant was related to OC and OPMD, in Argentine patients.

Transvagival sonography is superior to transabdominal sonography in most cases of pelvic pathology. Objective of this study is to evaluate the clinical usefulness of transvaginal ultrasonography (TVS) in pre, peri and post menopausal women suspected to have endometrial carcinoma. This cross sectional study was done with 40 patients who are clinically suspected having thickened endometrium. The study was carried out January 2007 to November 2008 for a period of two years. The patients having endometrial carcinoma diagnosed by TVS was correlated with histopathological diagnosis following collection of the report from the respective cases. Of total 40 cases, 2(5.0%) cases were endometrial carcinoma and 38(95.0%) were negative for endometrial carcinoma respectively in TVS findings. On the other hand 3(7.5%) cases were endometrial carcinoma and 37 (92.5%) cases were negative for endometrial carcinoma in histopathological findings. The validity of TVS in diagnosis of endometrial carcinoma were studied by calculating sensitivity, specificity, accuracy, positive predictive value and negative predictive value, which were 67 percent, 100 percent, 98 percent, 100 percent and 97 percent respectively. As the TVS findings of the present study correlated well with the histopathology findings and the validity test values were higher than observed by others, it can be concluded that TVS is sensitive and accurate modality in the evaluation of endometrial carcinoma.

ABSTRACT Oral squamous cell carcinoma is the most common malignancy of the oral cavity, which is usually preceded by a myriad of oral potentially malignant disorders (OPMDs). In the classification of OPMDs, inherited cancer syndromes (ICSs) were proposed as one of the categories. Inherited cancer syndromes are genetic disorders in which inherited genetic mutation in one or more genes predispose the affected individuals to the development of cancer and may also cause its early onset. Many of these syndromes are caused by mutations in tumor suppressor genes, oncogenes, and genes involved in angiogenesis. General dental practitioners frequently come across OPMDs in their day-to-day practice. It becomes of paramount importance to have knowledge about these rare but prognostically important OPMDs. With this view in mind, in this article, efforts have been made to comprehensively discuss about various ICSs that have higher potential of transformation into oral cancer. The ICSs discussed in this article are xeroderma pigmentosum (XP), ataxia telangiectasia (AT), Bloom syndrome (BS), Fanconi's anemia (FA), and Li–Fraumeni syndrome (LFS), with special emphasis on signs, symptoms, and genetic considerations.

Objective: To compare the accuracy of Upper lip bite test with modified Mallampati classification for predicting the difficultlaryngoscopic intubation. Study Design: Cross sectional Study. Place and duration of study: The study was carried out at Department ofAnaesthesiology, Intensive Care and Pain management, Combined Military hospital, Rawalpindi from September 2008 to August 2009.Patients and Methods: Four hundred patients undergoing elective surgery meeting the inclusion/exclusion criteria were enrolled afterwritten informed consent. The airways of the patients were evaluated by using the modified Mallampati classification (MMP) and theUpper lip bite test (ULBT). MMP class 3 or 4 and ULBT class 3 were considered as indicators of difficult intubation. The laryngeal view wasgraded by Cormack and Lehane classification (Gold standard). Grade 1 or 2 was considered to represent easy intubation and grade 3 or 4to represent difficult intubation. Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy werecalculated for both the tests separately by using the 2×2 table. Results: ULBT had a higher accuracy of 94%, specificity of 99.2% andpositive predictive value 70% compared to MMP accuracy of 82.7%, specificity of 84.4% and positive predictive value of 22.7%.Conclusions: The diagnostic accuracy of the Upper lip bite test was more than the modified Mallampati classification. We suggest that itbe compared with the other prevailing tests as well which are often used to assess difficult intubations.

Background: A walking cadence of ≥100 steps/min corresponds to minimally moderate intensity, absolutely defined as ≥3 metabolic equivalents (METs). This threshold has primarily been calibrated during treadmill walking. There is a need to determine the classification accuracy of this cadence threshold to predict intensity during overground walking. Methods: In this laboratory-based cross-sectional investigation, participants (N = 75, 49.3% women, age 21–40 y) performed a single 5-minute overground (hallway) walking trial at a self-selected preferred pace. Steps accumulated during each trial were hand tallied and converted to cadence (steps/min). Oxygen uptake was measured using indirect calorimetry and converted to METs. The classification accuracy (sensitivity, specificity, overall accuracy, and positive predictive value) of ≥100 steps/min to predict ≥3 METs was calculated. Results: A cadence threshold of ≥100 steps/min yielded an overall accuracy (combined sensitivity and specificity) of 73.3% for predicting minimally moderate intensity. Moreover, for individuals walking at a cadence ≥100 steps/min, the probability (positive predictive value) of achieving minimally moderate intensity was 80.3%. Conclusions: Although primarily developed using treadmill-based protocols, a cadence threshold of ≥100 steps/min for young adults appears to be a valid heuristic value (evidence-based, rounded, practical) associated with minimally moderate intensity during overground walking performed at a self-selected preferred pace.
