Abstract
OBJECTIVE The study was aimed to observe the changes in mean platelet volume in patients with sudden hearing loss, taking the close relationship of vascular reasons and sudden hearing loss into account. MATERIALS AND METHODS Patients who were admitted and treated with sudden hearing loss in the study. The control group was made up of healthy people. The hemoglobin values, mean platelet volumes, platelet counts of the groups were recorded. RESULTS Forty sixth patients in the sudden hearing loss group and 45 patients in the control group were evaluated. No statistically significant difference between the two groups regarding mean platelet volume values and platelet counts were found. There was also no significant difference between the high mean platelet volumes and hearing loss levels. CONCLUSIONS We think it would be beneficial to examine the mean platelet volume values in further studies with more patient series on patients with sudden hearing loss.

Abstract
OBJECTIVES In this study, we aimed to search whether gemcitabine - a commonly used antimetabolite type antineoplastic agent-has ototoxic effect. STUDY DESIGN AND SETTING An experimental animal research. SUBJECTS AND METHODS We evaluated the effect of gemcitabine on hearing through its possible effect on cochlea by using otoacoustic emission method on experimental rat model. For this purpose 16 healthy adult male Wistar albino rats were used and these were divided into 4 groups. The rats in the 1st, 2nd, 3rd and the 4th groups were given 40-160-240 and 320 mg/kg of intraperitoneal gemcitabine respectively. Distortion product otoacoustic emission measurements on both ears of each rat were performed before and 1 week after administration of gemcitabine. The mean of signal to noise ratio of emission values obtained from each rat before and after the drug administration were calculated. RESULTS Rats in the 1st group had no statistically significant difference at the emission rates before and after gemcitabine administration. A statistically significant decrease was observed in the emission rates at emission values of only 5 kHz in the 2nd group, at 4-6 kHz in the 3rd group, at 4-5-6-8 kHz in the 4th group. CONCLUSIONS Gemcitabine causes a decrease in otoacoustic emission values on experimental rat models at high doses and especially at high frequencies. Larger clinical and laboratory studies are needed to determine whether this decrease in emission rates are permanent and whether it has any permanent effect on hearing.

Abstract
This study assessed the need and readiness of health care institutions in Kabul and Bamyan, Afghanistan for successful implementation of information and communication technology in health care (eHealth). A mixed methods design was adopted at 2 institutions in the Aga Khan Development Network in Afghanistan: the French Medical Institute for Children in Kabul and Bamyan Provincial Hospital, Bamyan. Information for the needs assessment was obtained from interviews and focus groups and eHealth readiness was assessed using a validated survey tool. The needs of institutions in the Aga Khan Development Network in Afghanistan were categorized as follows: provision of care needs; learning needs; and information management needs. eHealth readiness on average was lower in Bamyan compared with Kabul in all areas of the readiness assessment. Other institutions in Afghanistan may benefit from adopting the model of needs and readiness assessment used for Aga Khan Development Network institutions.

Abstract
BACKGROUND Isolated nail dysplasia is rare and has been reported in only a small number of families. OBJECTIVES To describe and characterize two Pakistani families with an autosomal-recessive inherited nail dysplasia. METHODS Genome-wide linkage analysis; mutation screening of candidate genes by Sanger sequencing; cloning of FZD6 and protein analyses; immunohistochemistry. RESULTS We mapped this genodermatosis to chromosome 8q22.3, and identified a homozygous nonsense mutation c.1750G>T (p.E584X) in the frizzled 6 (FZD6) gene in all affected individuals. Immunohistochemical analyses in nail sections from healthy individuals revealed strong expression of FZD6 in the ventral nail matrix and a less pronounced expression of FZD6 in the nail bed. CONCLUSIONS FZD6 belongs to a family of proteins that serve as receptors in Wnt signalling pathways, and has been shown to act as a negative regulator of the canonical Wnt/β-catenin signalling cascade and a positive regulator of the noncanonical Wnt or planar cell polarity pathway. The present results therefore suggest that FZD6 plays a pivotal role in the growth and guidance of the nail plate in humans by acting as a molecular switch between different Wnt pathways. Previous studies have identified mutations in the RSPO4 and LMX1B components of the Wnt pathway in patients with the hypoplastic nail disorders anonychia and nail-patella syndrome, respectively. Only recently, FZD6 mutations were identified in isolated nail dysplasia. The present results emphasize the important role of the Wnt pathways in nail development and increase understanding of Wnt-mediated developmental events in general.

Abstract
Distinguishing keratoacanthoma from well-differentiated squamous-cell carcinoma is often difficult on account of the clinical and histopathological similarities between them. Since the outcome of treatment depends on identifying the correct diagnosis and having the correct treatment on time, it is essential to differentiate keratoacanthoma and squamous-cell carcinoma as soon and accurately as possible. A paradigmatic case is herein reported. An 85 year-old female underwent total parotidectomy and ipsilateral neck dissection due to the squamous-cell carcinoma of the parotid gland. The investigations, in order to determine whether the tumour was a metastatic or a primary one, led to a misdiagnosis. A prior skin lesion, which was excised over her left cheek one year ago in another clinic, was diagnosed as keratoacanthoma. However, the histopathological revision of the specimen revealed that the lesion was in fact a squamous-cell carcinoma. Thus the parotid tumour was accepted as metastatic squamous-cell carcinoma rather than primary squamous-cell carcinoma.
