Purpose: To determine the normal value of basal angle measured using the modified MR imaging technique in Thai population compared with the standard value obtained from the Western population. Material and Methods: We retrospectively evaluated midline sagittal SE T1 weighted MR images in 200 adults and 50 children. The basal angle of the skull base was measured using the modified MR imaging technique described by Koenigsberg et al. The angle was formed by a line extending across the anterior cranial fossa to the tip of the dorsum sellae and another line drawn along the posterior margin of the clivus. The mean values of the basal angles among different age groups and sex were calculated and analyzed. Results: The mean skull base angle of our adult population was 115° (range 100.5°-130°, SD=5.7) with an inter-observer agreement of 0.85, slightly smaller than the previous study from the USA which was 117°. There was no significant difference between the male and female groups. The mean skull base angle in our children population was 114.7° (range 102- 130.5°, SD=6.3) with an inter-observer agreement of 0.89, quite similar to the previous USA study which was 114°. There was no significant difference between adult and children. Conclusion: The mean adult skull base angle measured using the modified MR imaging technique in Thai population was slightly smaller than the Western population, while the mean skull base angle of children was quite similar. The basal angle range of 103.6°-126.4° may be used as a guide for the potential range of normal skull base angles in Thai population and possibly also the Southeast Asian population.

Aim: To evaluate sexual dimorphism in horizontal lip position in adults with different skeletal patterns. Material and Methods: The sample comprised of 120 patients (Females 18 years and above, Males 21 years and above) with no history of previous orthodontic treatment or functional jaw orthopaedic treatment. They were divided into different groups based on the ANB angle and gender. Group I and II included 30 males and 30 females with skeletal class I malocclusion (ANB 0-4 degree). Group III and IV included 30 males and 30 females with skeletal class II malocclusion respectively (ANB above 4 degree). Results: When comparison between males and females (Class I+Class II) was done S-line (p<0.001), B-line (p<0.001), E-line (p<0.001), Holdaways angle (p<0.001) and Merrifield angle (p<0.001) were found to be statistically significant. S-line (p<0.001), E-line (p<0.001) and Holdaways angle (p<0.001) were found to be statistically significant when comparison was done between males and females (Class I). When comparison was done between males and females (Class II) only Holdaways angle (p<0.001) showed a significant statistical difference. Conclusion: Sexual dimorphism was found in various lip parameters. Significant amount of differences were found between Class I and Class II (male and female) subjects.

Oral cancer has a tendency to be detected at late stage which is detrimental to the patients because of its high mortality and morbidity rates (survival rate 15-50% [1]). The incidence of oral cancer worldwide is approximately 3% of all malignancies, thus creating a significant worldwide health problem [2].

The patient is a 28-year old Caucasian man with six month history of arthralgia and crampy abdominal pain who presented with acute dyspnea and cough for 6 months associated with migratory polyarthralgias involving his knees, ankles, wrists, and shoulders.

The main method for evaluation of healing processes of the jaws in oral and maxillofacial surgery are radiological diagnostics. Quantitative description is possible by measuring the relative bone density, which puts the mean grey value of a certain area in relation to the surrounding bone tissue. In this research the intra- and interindividual variability is determined for this method and a standard operation procedure is elaborated. Therefore ten panoramic radiographs of typical surgical indications in oral a maxillofacial surgery were analyzed by three different members of the workgroup, five times each. The measurements were analyzed with descriptive and comparative statistical methods. The mean coefficient of variation was 2.972% ± 2.361%. The measurements of defect regions were more consistent (2.252% ± 1.928%) than the measurements of surrounding bone (3.691% ± 2.626%). The analysis of variance did not show a statistically significant influence of the different raters to the measurements (ANOVA, Pr>F = 0.9462). Following the standard operation procedure this method seems to be an easy, cheap and close to practice way to visualize healing process of the jaws. Especially in the mandibula, but also in the maxilla with special reconsideration of the sinus-region, it seems to be suitable.

Objective: The aim of the study was to determine the compliance to infection control of various dental laboratories in Durban. Study design: This was a qualitative survey. Setting: Dental laboratories in Durban area, South Africa. Subject: Registered laboratory technicians. Study methodology: Convenient random sampling method was used. Results: There was poor compliance to infection control procedures by most dental laboratories. Majority, 66.67%, of the dental laboratories relied on dental clinics for disinfection of dental impressions; therefore, they did not disinfect the impressions. On the other hand, only 33.33% carried out disinfection of dental impressions on their own. A high number (53.3%) of the respondents had disinfection areas within their dental laboratories, 6.7% had no disinfection areas while 40% depended upon dental clinics for all disinfections. About 60% of the dental technicians had valid vaccinations against Hepatitis B Virus while 40% had no vaccination against HBV. Conclusion: The results of this study indicated that there was substantial nonconformity to infection control measure in all dental laboratories. There should be comprehensive inspection of dental laboratories prior to licensing and thereafter by the South African Dental Technician Council’s inspectors to ensure that all dental laboratories comply with the various infection control measures.

This report presents an adult patient suffering from sacroiliitis like low back pain, lumbosacral radiculopathy and elbow swelling. Multimodality imaging revealed multiple lytic bone lesions located in supra acetabular iliac bone, sacrum, and distal end of radius. Painful numerous lesions due to the extension to the articular surfaces are not expected for Brown tumors. Less than ten cases with multiple Brown tumor due to primary hyperparathyroidism has been reported. Although Brown tumors are mostly diagnosed incidentally, this case would awake the physicians about rheumatological symptoms in the presentation of Brown tumors. Since Brown tumors are non-touch bone lesions that are expected to regress after parathyroid adenoma removal, it is important to distinguish Brown tumors from the giant cell tumors.

Breast cancer is a complex disease and one of the main causes of cancer-related mortality in women worldwide. In case of approximately 15% of all breast cancers, three markers i.e. estrogen receptors (ER), progesterone receptors (PR) and human epidermal growth factor receptors-2 (HER2) are not expressed, and is commonly termed as triple-negative breast cancer (TNBC). Particularly, TNBC is associated with a higher percentage of breast cancer related mortality, which is often aggressive and most frequently found with a BRCA1 mutation or increased basal marker expression. However, due to the limitations of chemotherapy and radiation based treatment; the current challenge is to establish a new strategy of diagnosis and treatment of TNBC. The deregulation of a number of microRNAs (miRNAs) in breast cancer has been widely reported. Therefore, this review is directed towards enhancing our understanding of the involvement of various miRNAs in the pathology of TNBC, their upregulations and downregulations and the effects on various factors. From recent studies a number of miRNAs are found to be related with TNBC, which have great potential to be used as a biomarker to determine the disease prognosis and predict the fate of disease. Again miRNA can be targeted to be applied as a therapeutic to provide a great benefit to the patients of TNBC by finding a new, safe, and effective treatment strategy.

The greater risk of hypernatremia in patients over 65 years old are associated with impaired mental status and physical disability which may result in impaired sensation to thirst, impaired ability to express thirst, and/or decrease access to water [1,2]. Normally, anti-diuretic hormone (ADH, also known as arginine-vasopressin, AVP) is secreted in response to 1-2% increase in osmolality which stimulate thirst, as do hypovolemia and hypotension.

Anoikis resistance (AR) is a favorable attribute exhibited by cancer cells for metastasis. Carcinoma associated Fibroblasts (CAFs) plays a crucial role in AR in various cancers. It was proved in array of studies in different cancers that there was definite interrelationship between CAFs and AR. But its role in OSCC is ambiguous. It is the need of the time to reveal the correlation of CAF and oral squamous cell carcinoma (OSCC) in relation with anoikis. Molecular pathways which affects the AR via CAFs in various cancers has been highlighted in this communication. Divulging the importance of CAF in cancer will aid in designing customized novel chemoprevention therapy and thus will help in enhancing the prognosis of patient in OSCC.
