Reliability and Validity of the Turkish Version of Illness Cognition Questionnaire

Background: This study aimed to determine the validity and reliability characteristics of the Illness Cognition Questionnaire (ICQ).

Methods: A total of 205 patients who had pain related to chronic musculoskeletal diseases were referred to the study. In order to test the validity, Short Disease Perception Scale (SDPS), Hospital Anxiety and Depression Scale (HADS) were administered together with the ICQ. Confirmatory factor analysis was used to measure the construct validity of the ICQ, and convergent and divergent validities were evaluated using Pearson correlation analysis. In order to achieve the test-retest reliability of the questionnaire, 81 patients re-applied the questionnaire after two days. Cronbach’s alpha internal consistency and test-retest reliability coefficients were calculated to determine the reliability level of the questionnaire.

Results: The factor loadings of the ICQ helplessness subscale ranged from 0.784 to 0.853, the acceptance subscale ranged from 0.583 to 0.855, and the perceived benefits subscale ranged from 0.733 to 0.794. Internal consistency coefficients of the ICQ were found α = 0.929 for the helplessness subscale, α = 0.868 for the acceptance subscale, and α = 0.896 for perceived benefits subscale. The results of the analysis showed that there was a statistically significant positive correlation between the initial measurement of helplessness sub-scale and the retest helplessness subscale at 0.697 level (p < .05). A statistically significant positive correlation was determined between the test and the retest of acceptance sub-scale at 0.465 level (p < .05). A statistically significant positive correlation was found between the first test of the perceived benefits sub-scale and the retest test at the 0.661 level.

Conclusion: The Turkish version of the ICQ was found to be valid and reliable. It is a measurement tool that could be used easily in clinics because of its short application time and easy to understand. We think that ICQ which provides a new awareness in the perception of disease in Turkish society should be examined in different diseases and age groups.     

Unexpected breakage of mandibular midline distraction device: case report.

Management of the transverse mandibular deficiency and anterior crowding by mandibular midline distraction osteogenesis (MMDO) is an efficient and stable alternative to orthodontic mechanics with minor complications. Although the only major complication reported previously during MMDO is the nonunion of the segments, in the present case report an unexpected breakage of the distractor in MMDO during the consolidation period as a new major complication was presented.     

Spontaneous gastrosplenic fistula in primary gastric lymphoma: Surgical management

Gastrosplenic fistula formation resulting from primary gastric malignancy is rare and should be managed as a matter of emergency. We report a patient who was diagnosed with primary non-Hodgkin's lymphoma and who underwent surgical treatment for gastrosplenic fistula.     

Effect of mitomycin C on ciliary body and intraocular pressure with various application depths: an experimental study

BACKGROUND: To evaluate the effects of mitomycin C (MMC) on intraocular pressure (IOP) and ciliary body via transmission electron microscopy when applied under conjunctiva or different depths of sclera, without performing any filtering surgery. METHODS: Thirty-six eyes of 36 New Zealand albino rabbits were used in this study. MMC was prepared in a concentration of 0.4 mg/mL and 0.05 cc (20 microg) was soaked in preprepared sterile surgical sponges. Six groups each consisting of six eyes were formed and IOP was measured preoperatively. Group 1 was the control group: the superior conjunctiva was opened and only irrigated with balanced salt solution (BSS). In group 2, MMC soaked sponges were applied under the conjunctiva. In groups 3 and 4, a scleral flap of approximately 1/3 scleral thickness was prepared and in groups 5 and 6, and a scleral flap of approximately 2/3 scleral thickness was prepared, all with a standard size of 4 x 4 mm. MMC soaked sponges were applied under these areas for 5 min in eyes in groups 3 and 5 followed by an irrigation of the relevant areas with 10 cc BSS, whereas only irrigation with BSS was done in groups 4 and 6 as control groups. No filtering procedure was performed in any of the eyes. Eyes were enucleated on the 30th day following measurement of IOP and the ciliary body regions were evaluated using transmission electron microscopy. Kruskal-Wallis test was used for the statistical assessment of IOP between groups. RESULTS: The deep scleral flap group (group 5) showed statistically significantly more IOP reduction than both the superficial scleral flap group (group 3; P = 0.004) and the subconjunctival group (group 2; P = 0.002) on postoperative day 30. Electron microscopic evaluation of the surgical groups revealed a wide range of different histopathological effects due to different MMC application methods. The histopathological changes were more evident in the group 5, where MMC was applied under deep scleral flap. CONCLUSIONS: Subscleral application of MMC seems to provide greater IOP decrease than subconjunctival application, possibly caused by a more significant ciliary body toxicity. This may be the beginning of a non-penetrating, easy to perform and safe method to decrease IOP in glaucoma patients, which the authors call 'toxic ciliary ablation surgery'. However, the long-term results and complications must be assessed with further studies.     

Microscopic polyangiitis presenting with medullary infarct

Microscopic polyangiitis is a small vessel vasculitis which is rarely associated with ischemic stroke. Cerebrovascular disease has rarely been reported in connection with this disease. It may cause fatal hemorrhage, hemorrhagic conversion and multiple lacunar infarcts. We report here a 55-year-old woman with left medullary oblangata infarction without any symptoms of microscopic polyangiitis. During hospitalization, retinal ischemia, mononeuritis multiplex and pulmonary infiltration developed. Sural nerve biopsy was concomitant with small vessel vasculitis. Elevated CRP and sedimentation and positive P-ANCA led to confirmation of a diagnosis of microscopic polyangiitis. Our patient is a rare case of microscopic polyangiitis presenting with medullary infarction. Although the characteristics of this disease are well-known, the first symptom can be a medullary infarction, which has not been reported in literature before.     

What is the importance of radiology in obstructive sleep apnea?

Lipomas are rare, and they rarely arise in deep soft tissue. Only few cases associated with obstructive sleep apnea (OSA) have been reported. Because of radiologic examinations (computed tomography and magnetic resonance imaging) in a case with OSA, a rarely observed large lipoma was encountered in the retropharyngeal region. In the case that was followed, the apnea-hypopnea index was measured. The radiologic examination of the upper airway of the case with OSA symptoms was presented.
