Abstract
PURPOSE To evaluate cytogenetic damage of radiotherapy (RT) and chemoradiotherapy (CRT) in long-term head and neck cancer survivors. MATERIALS AND METHODS This study included 20 patients treated with RT (10 patients) or CRT (10 patients) for head and neck cancer. Nine healthy volunteers were included as control subjects. Cytochalasin B-blocked micronucleus (CBMN) assay was used to evaluate cytogenetic damage. To evaluate micronucleus (MN) by CBMN, the venous blood samples were drawn median 68 months (range 60-239 months) after the completion of treatment (RT or CRT) for head and neck cancer. RESULTS Nuclear division index (NDI) and number of MN in mononuclear and binuclear lymphocytes were significantly higher in patients with head and neck cancer than in control subjects [1.19 (1.08-1.47) vs. 1.07 (1.04-1.14), p < 0.001; 11.0 (2.0-22.0) vs. 1.0 (0-3.0), p < 0.001 and 15.0 (5.0-45.0) vs. 9.0 (2.0-15.0), p = 0.020, respectively]. NDI and number of MN in mononuclear lymphocytes were significantly lower in control subjects compared patients received CRT and those received only RT, but there was no significant difference between patients received CRT and those received only RT. Number of MN in binuclear lymphocytes was significantly lower in control subjects compared to patients received CRT, but there was no significant difference between control subjects and those received only RT. Also there was no significant difference between patients received CRT and those received only RT in terms of number of MN in binuclear lymphocytes. CONCLUSIONS MN frequency of mononuclear and binuclear lymphocytes in medical follow-up of patients with head and neck cancer after RT could be important in evaluating cytogenetic damage of RT. However, further investigations are needed to provide quantitative correlations between MN yields and the clinical features in post-radiotherapy period.

Abstract
Warburg Micro Syndrome (WARBM, MIM 600118) is a rare, severe autosomal recessive neurodevelopmental disorder characterized by microcephaly, microphthalmia, microcornea, congenital cataract, cortical dysplasia, corpus callosum hypoplasia, intellectual disability, hypotonia and hypogonadism. RABS, small G proteins belonging to the RAS superfamily, are master regulators of vesicle trafficking in the cell. The identification of mutations in the RAB3GAP1 and RAB3GAP2 genes, which together encode the RAB3GTPase-activating protein, a key regulator in calcium-mediated exocytosis of neurotransmitters and hormones, has underpinned abnormal development of the brain, eye and genitalia as cardinal features of this syndrome. More than 100 patients have been reported with WARBM, with mutations in the RABGAP1, RABGAP2, RAB18 and TBC1D20 genes. The objective of the study was to describe the recurrent RAB3GAP1 mutations and compare the clinical features of the patients with WARBM in the Turkish population. Here we report two brothers with Warburg Micro Syndrome 1 from a non-consanguineous Turkish family with clinical features similar to those previously reported in Turkish patients with RAB3GAP1 mutations. We found that the c.748+1G>A splice-site mutation in RAB3GAP1 intron 8 is common and has so far only been detected in patients of Turkish ethnic origin. Although one of our patients has a distal extra crease on the 4th finger and another has nephrolithiasis, there does not appear to be any specific phenotypic findings associated with this mutation.

Abstract
We present a male child at 3 years old with Anophthalmia-Plus Syndrome (APS). He has asymmetry of the face and head, left choanal atresia, a sunken facial appearance, microphthalmia in the right eye, severe microphthalmia in the left eye, bilateral low-set ears, scarring from cleft palate surgery. Magnetic resonance imaging (MRI) sections revealed decreased right globe volume, an undeveloped left globe, decreased left optical nerve thickness, Chiari type 2 malformation, left choanal atresia and cleft palate. Echocardiography and abdominal ultrasonography were normal. The patient has a 45 dB conductive hearing loss in the left ear. Repeated thyroid function tests were evaluated as compatible with central hypothyroidism. We report a Fryns Anophthalmia-Plus Syndrome in a child with unusual findings including central hypothyroidism, chiari type 2 malformation, conductive hearing loss and developmental regression. Summary of the features reported in the present case and all 14 previous cases that might be defined as APS.

Abstract
A 19-year-old female patient was admitted to our hospital with dyspnea, chest pain, and shortness of breath. A chest radiograph showed mild cardiomegaly. Echocardiography revealed an extra chamber in the heart. To evaluate this abnormality, ECG-gated 16-detector-row computed tomography angiography was performed. Multidetector computed tomography (MDCT), showing cor triatriatum with total anomalous pulmonary venous connections (TAPVC), clearly revealed cardiac and vascular anatomy. ECG-gated cardiac MDCT is a useful tool for detection and characterisation of cor triatriatum and related anomalies.

Abstract
Nasal packing may influence the mucociliary clearance of the nose in the postoperative healing phase. In an attempt to overcome some of this problem, a haemostatic septal suturing technique was conceived. In this prospective study, we aimed to investigate the effects of nasal packing and septal suturing technique on mucociliary clearance by rhinoscintigraphy. Forty-eight adult patients who had undergone septoplasty were included in the investigation. Preoperatively, the patients were allocated into three groups: group 1, fingerstall packs filled with gauze and smeared with vaseline were used (11 male, 4 female); group 2, silicon septal splint packs were used (11 male, 4 female); group 3, haemostatic septal sutures were used (14 male, 4 female). Mucociliary clearance was measured by rhinoscintigraphy in all patients before surgery and 6 weeks after surgery. The nasal mucociliary clearance was presented as the velocity (mm/min) of nasal mucociliary transport of the (99m)Tc-MAA droplet. The mean velocity of nasal mucociliary clearances before and after surgery for group 1, group 2 and group 3 were 1.85 +/- 0.67 versus 2.43 +/- 0.78 mm/min, 2.36 +/- 0.80 versus 2.92 +/- 0.96 mm/min and 2.03 +/- 0.58 versus 2.62 +/- 0.65 mm/min, respectively. A significant difference in nasal mucociliary clearance was observed after surgery in all groups (p < 0.001). No significant differences were found between the groups regarding mucociliary clearance before and after surgery. Patients with septal deviation have a prolonged mucociliary transit time as compared with postoperative. Nasal packing did not significantly influence the mucociliary clearance in the postoperative healing phase.

Abstract
UNLABELLED This study was carried out to determine the characteristics and incidence of hearing loss and vestibular disturbance in Behcet's syndrome with a large number of patients. Sixty-two patients with Behcet's syndrome were included in this study, 34 men and 28 women whose mean age was 33.7 (15-60). Sixty-two healthy normal control subjects (38 male and 24 female) were included. Patient and control groups were questioned about any history of audio-vestibular disturbance and underwent physical and ENT examination and the following audiologic tests: pure tone audiometric test (0.25, 0.5, 1, 2, 4, and 6 kHz), tympanogram, speech discrimination, short increment sensitivity index, tone-decay test, auditory brainstem response. Vestibular system was evaluated by videonistagmogram and caloric test. Cranial and brainstem magnetic resonance imagine (MRI) of patients who have vestibular disturbances were practiced to examine the central nervous system. Both the patient and the control groups were tested with the HLA-B51 antigen. Pure tone audiogram showed sensory-neural hearing loss (25 dB hearing level in at least two frequencies) in 20 of the 62 (32%) Behcet's patients while the control group were normal. There was a hearing loss involving high frequencies in the audiograms of Behcet's patients with hearing disturbances. The recruitment investigation tests and auditory brain stem response confirmed cochlear involvement in all 20 patients. Caloric stimulation tests revealed a normal vestibular function in all patient and control group. In electronystagmography, 21 (34%) patients had hypometric or hypermetric saccades and smooth pursuit tests showing that 4 (6%) patients had pathological changes while the control group was normal. HLA-B51 antigen was found positive in 15 of 20 Behcet's patient with hearing loss. CONCLUSION (1) The hearing and vestibular disturbances in Behcet's syndrome is more prevalent than previously recognized; (2) Hearing loss in high frequencies in Behcet's patients is an indicator of cochlear involvement in this disease; (3) There is a higher prevalence of central vestibular syndrome in Behcet's patients than it was thought before; (4) HLA-B51 antigen may be able to be a prognostic factor for sensorineural hearing loss in Behcet's patients.
