Multicenter Prospective Observational Study

Objective Transoral surgery is becoming a preferred technique because it does not leave any scar after surgery. However, transoral surgery for a dermoid cyst of the oral cavity is not standardized yet, due to the anatomic complexity of this region. The aim of this study was to evaluate the safety and efficacy of a transoral dermoid cyst excision. Study Design Multicenter prospective observational study. Setting University hospital. Subjects and Methods This study was designed as a 4-year prospective multicenter evaluation of dermoid cyst excisions within the floor of mouth. Clinical outcomes and complications related to procedures were evaluated among patients. The primary outcome was the efficacy of the procedure, and the secondary outcome was cosmetic satisfaction of each procedure. Results Twenty-one patients underwent transoral dermoid cyst excisions, and 22 underwent transcervical excisions. In the transoral surgery group, the mean size of the dermoid cyst was 5.35 cm (95% CI, 4.79-5.91), and in the transcervical surgery group, it was 6.19 cm (95% CI, 5.67-6.71). There was no significant differences with respect to overall demographic characteristics between the groups. However, the duration of the operation was shorter with the transoral group than with the transcervical group ( P = .001), and cosmetic satisfaction was much better in the transoral group ( P < .001). Conclusion Transoral dermoid cyst excision is a potentially safe and effective method that can lead to easy and quick removal of an oral cavity dermoid cyst, with excellent cosmetic outcomes.

Retinoblastoma and other eye tumors in childhood are rare diseases. Many eye tumors are the first signs of a genetic tumor predisposition syndrome and the affected children carry a higher risk of developing other cancers later in life. Clinical and genetic data of all children with eye tumors diagnosed between 2013–2018 in Germany and Austria were collected in a multicenter prospective observational study. In five years, 300 children were recruited into the study: 287 with retinoblastoma, 7 uveal melanoma, 3 ciliary body medulloepithelioma, 2 retinal astrocytoma, 1 meningioma of the optic nerve extending into the eye. Heritable retinoblastoma was diagnosed in 44% of children with retinoblastoma. One child with meningioma of the optic nerve extending into the eye was diagnosed with neurofibromatosis 2. No pathogenic constitutional variant in DICER1 was detected in a child with medulloepithelioma while two children did not receive genetic analysis. Because of the known association with tumor predisposition syndromes, genetic counseling should be offered to all children with eye tumors. Children with a genetic predisposition to cancer should receive a tailored surveillance including detailed history, physical examinations and, if indicated, imaging to screen for other cancer. Early detection of cancers may reduce mortality.

Objective: To compare Helicobacter pylori ( H. pylori) eradication rate of type 2 diabetic patients with non-diabetic subjects. Methods: In this multicenter prospective observational study, H. pylori-infected subjects were enrolled from three university-affiliated hospitals. Eradication regimen was triple therapy with standard dose of proton pump inhibitors (b.i.d), amoxicillin (1.0 g b.i.d), and clarithromycin (500 mg b.i.d) for 7 days. Urea breath test was performed 4 weeks after treatment. Various clinical and laboratory data were collected for identification of factors associated with successful eradication. Results: Totally, 144 subjects were enrolled and 119 (85 non-diabetic and 34 diabetic patients) were finally analyzed. Eradication rate was 75.6% and there was no difference between diabetic patients and non-diabetic subjects (73.5% vs 76.5%, p value: 0.814). Adverse drug reactions were reported in 44.5% of patients. In multivariate analysis for predicting H. pylori eradication in diabetic patients, HbA1c (⩾7.5%) was a significant factor affecting eradication rate (adjusted odds ratio: 0.100, 95% confidence interval: 0.011–0.909, p value: 0.041). Conclusion: Diabetes itself is not a major factor affecting H. pylori eradication. However, poor glucose control may harmfully affect H. pylori eradication.
