Investigation of temporal bone asymmetry in cases with unilateral tinnitus: morphometric and multicentric clinical study

The aim of this multicentric study was to compare the anatomical structures of temporal bone in patients with unilateral tinnitus with their healthy ears. We also aimed at evaluating whether age and gender-related asymmetrical changes occur in temporal bones or not. Fifty two ears of 26 patients who had unilateral tinnitus were included into the retrospective study. The patients who had subjective nonpulsatile tinnitus and who previously had temporal computed tomography according to their file records were accepted to study. Temporal CT scans and audiometric results of patients were examined retrospectively. Middle ear volume, diameter of internal acoustic meats and diameter of jugular bulb were evaluated by both anatomist and radiologist, interobserverly. Internal acoustic meats and jugular bulb were found larger in the ears that had tinnitus than healthy ears; however, there was no statistically significance. The stereological morphometrical study of temporal bone asymmetry in humans correlate with sex is of importance for both otolarygologs and anatomists. These results will contribute to data on middle ear volume, internal acustic meats and jugular bulb sizes

Expert consensus document: Clinical and molecular diagnosis, screening and management of Beckwith-Wiedemann syndrome: an international consensus statement.

Beckwith-Wiedemann syndrome (BWS), a human genomic imprinting disorder, is characterized by phenotypic variability that might include overgrowth, macroglossia, abdominal wall defects, neonatal hypoglycaemia, lateralized overgrowth and predisposition to embryonal tumours. Delineation of the molecular defects within the imprinted 11p15.5 region can predict familial recurrence risks and the risk (and type) of embryonal tumour. Despite recent advances in knowledge, there is marked heterogeneity in clinical diagnostic criteria and care. As detailed in this Consensus Statement, an international consensus group agreed upon 72 recommendations for the clinical and molecular diagnosis and management of BWS, including comprehensive protocols for the molecular investigation, care and treatment of patients from the prenatal period to adulthood. The consensus recommendations apply to patients with Beckwith-Wiedemann spectrum (BWSp), covering classical BWS without a molecular diagnosis and BWS-related phenotypes with an 11p15.5 molecular anomaly. Although the consensus group recommends a tumour surveillance programme targeted by molecular subgroups, surveillance might differ according to the local health-care system (for example, in the United States), and the results of targeted and universal surveillance should be evaluated prospectively. International collaboration, including a prospective audit of the results of implementing these consensus recommendations, is required to expand the evidence base for the design of optimum care pathways

Effect of 23 valent pneumococcal polysaccharide and Haemophilus influenza conjugated vaccines on the clinical course of otitis media with effusion

WOS: 000179193300024PubMed: 12439177Objective. To determine if there is any clinical effect of 23-valent pneumococcal and Haemophilus influenza type B conjugate vaccine on prognosis of otitis media with effusion. Method: All children who have middle ear effusion despite long-standing antibiotherapy with a beta lactamase stable agent were offered for tympanostomy tube insertion between February 1999 and December 2001. Patients who accepted the surgical intervention were operated under general anesthesia and a Shepard grommet-type tympanostomy tube was inserted. Those who refused the surgical intervention were vaccinated with 23-valent pneumococcal and Haemophilus influenza type B conjugate vaccine. State of the middle ear effusion was evaluated at the end of the 12th month in the vaccine group and 1 month after the myringotomy site was healed in the tympanostomy tube insertion group. Results: Twenty-six children in the vaccine group and 37 children in the tympanostomy tube insertion group proved the inclusion criteria at the end of study. Complete or partial resolution of middle ear effusion was observed in 73.1% of 26 children in the vaccine group and 59.5% of children in the tympanostomy tube insertion group. There was no significant difference between the two groups. Conclusion: Vaccination against Streptococcus pneumonia and Haemophilus influenza type b seems to aid resolution of middle ear effusion in children with otitis media with effusion

Mass spectrometry guided venom profiling and bioactivity screening of the Anatolian Meadow Viper, Vipera anatolica

WOS: 000366539600002PubMed ID: 26385313This contribution reports on the first characterization of the venom proteome and the bioactivity screening of Vipera anatolica, the Anatolian Meadow Viper. The crude venom as well as an isolated dimeric disintegrin showed remarkable cytotoxic activity against glioblastoma cells. Due to the rare occurrence and the small size of this species only little amount of venom was available, which was profiled by means of a combination of bottom-up and top-down mass spectrometry. From this analysis we identified snake venom metalloproteases, cysteine-rich secretory protein isoforms, a metalloprotease inhibitor, several type A2 phospholipases, disintegrins, a snake venom serine protease, a C-type lectin and a Kunitz-type protease inhibitor. Furthermore, we detected several isoforms of above mentioned proteins as well as previously unknown proteins, indicating an extensive complexity of the venom which would have remained undetected with conventional venomic approaches.

Melanotic neuroectodermal tumor of infancy in the skull: a case report

Melanotic neuroectodermal tumor of infancy (MNTI) is a rarely occurring neoplasm of neural crest origin, appearing in children during the first year of life. MNTI is a benign tumor but is nonetheless locally aggressive; it usually originates from the maxilla and the mandible. Recognition of the diagnostic features of MNTI is important, so that it may be differentiated from benign lesions (dermoid or epidermoid cysts, vascular lesions) as well as from malignant lesions such as small round cell tumors. We present a case of a 2-month-old infant who developed right retroauricular swelling with extension through the calvarium and into the central nervous system. The tumor was totally resected. Aggressive benign or malignant lesions of the calvarium may entail dural infiltration and brain involvement, as in our case. Early diagnosis and surgery are thus mandatory for benign or malignant tumors of the calvarium
