RESUMO

Background: Cell adhesion molecules (CAMs) are found on the surface of all cells, where they allow dynamic processes to take place. These include cadherins, integrins, selectins and Immunoglobulin superfamily. Directly associated with ß-integrin tails is a multidomain protein known as paxillin. However, CAMs participate in cell-cell and extracellular matrix-cell interactions during histomorphogenesis in the various phases of odontogenesis. Some tumours or cysts like ameloblastoma (AB) or odontogenic keratocyst (OKC) having odontogenic origin show disturbance in the interaction of these CAMs. Hence, the assessment of paxillin expression in AB and OKC was carried out. Materials and Methods: The present observational study comprised 30 clinically and histologically confirmed cases of AB and OKC. All the slides were stained immunohistochemically using a paxillin antibody. Results: Upon comparison of staining intensity of paxillin among AB and OKC showed statistically significant result, whereas quantitative staining and final summation showed non-significant result. Gender-wise comparison of paxillin staining intensity, quantitative staining and final summation among OKC showed significant result; however, in AB, staining intensity showed non-significant result, whereas quantitative staining and final summation showed significant result. Conclusion: Paxillin has the greatest influence on tissue morphogenesis and development. The regulation of cell mobility is aided by the multiple roles that paxillin plays in a range of cells and tissues. However, further studies using a large sample size, along with other molecular analytical methods, may be essential to draw a definite conclusion about the association of paxillin and its exact function in OKC and AB.

RESUMO

Ewing sarcoma is a lesion of bone, described in small round cell neoplasm. This tumour resembles primitive neuroectodermal tumour both clinically and histologically. Major difference between these two is that the former arises in the bone and the later in soft tissue. It appears most frequently in males at the age range of of 5-25 years, 80% of which occurs within first two decades of life. Males are more commonly affected than females. Present paper reported with a case report of male patient with 24-year-old showing Ewing's sarcoma of right maxilla.

RESUMO

BACKGROUND: Oral squamous cell carcinoma is a major contributor to disability and death caused by malignant tumors. Variations in social, cultural, and geographic factors affect the tumor behavior and response to treatment. In this study, we undertake a seven years institutional review and analysis of Oral squamous cell carcinoma cases in Bareilly. MATERIALS AND METHODS: A total of 1938 histologically diagnosed cases during the period of seven years i.e. from 2010 to 2016 were extracted from the archives of Department of Oral & Maxillofacial Pathology, Institute of Dental Sciences, Bareilly and evaluated to know the prevalence of Oral squamous cell carcinoma. The details like age, sex, habits and anatomical site were also recorded from the archived patient's case sheets. RESULTS: Out of the total 1938 cases, 318 were found to be Oral squamous cell carcinoma of which 232 were males and 86 were females. Incidence was highest in 40-49 year age group. The most common site was buccal mucosa (190 cases), followed by tongue (68 cases). Most lesions were well differentiated Oral squamous cell carcinoma (230 cases). Patients with poorly differentiated lesions had a comparatively lower mean age than their counterparts with other histological varieties. CONCLUSION: The pattern of Oral squamous cell carcinoma differs from that of previous studies in relation to incidence and age correlation with the grade of carcinoma. The majority of the lesions were well differentiated. There is a need for intensive oral health awareness to encourage early presentation to cancer center as early detection will further enhance prognosis.

RESUMO

BACKGROUND AND OBJECTIVES: Among morphological characteristics that differentiate a male from a female, tooth size has also been evaluated in various populations for its applicability in anthropologic and forensic investigations to identify the gender from dental remains. The present study was undertaken to investigate the accuracy of mesio-distal width of the mandibular canines, inter-canine arch width, and Mandibular Canine Index (MCI) with which gender can be differentiated in Moradabad population and to correlate the results with other available data. MATERIALS AND METHODS: A cross-sectional study was conducted on the casts of 30 males and 30 females between the age group of 19-30 years. RESULTS: The mean right and left canine dimension (RCW and LCW) for females was between 6.28 mm and 6.54 mm while that of males was 7.06 mm and 7.45 mm. The mean inter-canine arch width (ICW) in males was 27.64 mm, whereas in females was 23.42 mm. Area under curve (AUC) of ICW, RCW, and LCW had 100%, 98%, and 99.7%. The predicted sensitivity and specificity observed of three criteria was 100% for ICW, 93.3% and 93.3% for RCW, and 96.7% and 100% for LCW, which were found to be highly statistically significant. The mean values of right and left CMI were significantly higher in females as compared to males (P < 0.001). CONCLUSION: The MCI parameter in the present study was a quick and reliable method for sexual identification and showed sexual dimorphism by both the RMCI and LMCI with greater significance in identifying females by using RMCI.

RESUMO

Candida is the shortened name used to describe a class of fungi that includes more than 150 species of yeast. In healthy individuals, Candida exists harmlessly in mucus membranes such as your ears, eyes, gastrointestinal tract, mouth, nose, reproductive organs, sinuses, skin, stool and vagina, etc. It is known as your "beneficial flora" and has a useful purpose in the body. When an imbalance in the normal flora occurs, it causes an overgrowth of Candida albicans. The term is Candidiasis or Thrush. This is a fungal infection (Mycosis) of any of the Candida species, of which Candida albicans is the most common. When this happens, it can create a widespread havoc to our overall health and well-being of our body.

RESUMO

Introduction. Gorlin-Goltz syndrome is an inherited autosomal dominant disorder with complete penetrance and extreme variable expressivity. Case Report. The present paper highlights the importance of diagnostic criteria and histopathology in early and prompt diagnosis which will lead to proper treatment and genetic counseling of the patient. Discussion. Gorlin-Goltz syndrome is about multisystem process comprising the triad of basal cell nevi, jaw keratocysts, and skeletal anomalies. A spectrum of other neurological, ophthalmic, endocrine and genital manifestations is known to be variably associated with this triad. Diagnosis of the syndrome is based on major and minor criteria. Conclusion. This paper emphasizes the importance of oral and maxillofacial health professionals in the early diagnosis of nevoid basal cell carcinoma syndrome and in a preventive multidisciplinary approach to provide a better prognosis to the patient.
