Age-related changes of nasal cavity and conchae volumes and volume fractions in children: a stereological study

Background: The anatomy of the human nasal cavity (NC) is complex and its structures are closely related to the functions of the NC. Studies which assessing the mean volumes of NC and conchae are very infrequent. The purpose of current study is to investigate development of NC and conchae according to age and sex by using stereological method. Materials and methods: This retrospective volumetric study was carried out on 342 individuals (166 females and 176 males) between 0 and 18 years old with no pathological conditions or medical procedures that affected the skeletal morphology of the NC. Volumetric estimations were determined on computed tomography (CT) images using point-counting approach of stereological methods. Results: NC, inferior nasal conchae (INC) and middle nasal conchae (MNC) volume measurements that obtained using point-counting method were increased with age in both sexes until 15 years old. Regardless of gender; no significant difference was determined between the left and right values for NC, conchae volumes and choanae measurements. Generally, significant differences were determined in NC and INC volumes according to gender after they reached maximum growth period. According to age the volume ratios of INC to NC and MNC to NC were ranged from 18% to 32% and 9% to15%, respectively. Conclusions: The current study demonstrated that the point-counting method is effective in determining volume estimation of NC and is well suited for CT studies. Our results could provide volumetric indexes for the NC and conchae, which could help the physician for both patient selections for surgery, and for the assessment of any surgical technique used to treatment of nasal obstruction.

Tumoral calcinosis with unusual radiographic findings (a case report)

Tumoral calcinosis, an ectopic calcification syndrome characterized by soft tissue calcium particle deposits in the absence of widespread viscera; involvement

Oral lichen planus and chronic liver disease

In recent years, it has been suggested that three may be arelation between lichen planus and the hepatic diseases, but this relation is ques tionabl. Some researchers recmommend that patients with lichen planus should be observed carefully for an underlying hepatic disease. In our study, AST and ALT levels of 35 patients who are diagnosed clinically and histopathologically as having oral lichen planus are measured, and they are investigatid as to the possibility of Hepatitis B. Ic has been determined that serum AST and ALT levels have been within normal limits and no significant difference has been established as compared to the control group. Hepatitis B antigens are found to be negative

Comparison of a New Medicinal Plant Extract and Triamcinolone Acetonide in Treatment of Recurrent Aphthous Stomatitis

The aim of this study was to evaluate the effectiveness of a new medicinal plant extract (Ankaferd Blood Stopper®, ABS) on the healing process of aphthous ulcers. A total of 50 patients with recurrent aphthous stomatitis (RAS) who have had currently a single oral ulcer in the mouth were included in the study. Patients were randomly divided in 2 groups: ABS group and Kenacort group (triamcinolone acetonid). Data were collected by questionnaire regarding age, gender, RAS history including the number of ulcer episodes in 1 month, the number of ulcers in each episode, mean healing time of previous ulcers and the mean disease duration. Ulcer size, ulcer related pain, evaluated by VAS and effectiveness index (EI), was noted in each clinical examination
