We report a case of rapidly involuting congenital hemangioma of the flank, which was diagnosed in the 2nd trimester of gestation and showed complete involution before term. In our case sonography revealed a highly vascular soft tissue mass with smooth contours, which was isointense with the placenta on T2-weighted MR images. The fetus was born with scar tissue at the site of the lesion. To our knowledge this is the 1st reported case of rapidly involuting congenital hemangioma showing complete involution before term. © 2009 Wiley Periodicals, Inc.

Intraoperative imaging technologies have improved surgical results in glioma and pituitary adenoma surgeries. With improvements and refinements 3T intraoperative MRI systems offer a potential of further improving these results. Hereby we describe the equipment and technique of a cost-effective shared-resource 3-T ultra-high field intraoperative magnetic resonance imaging system and report our continuing experience on surgical tumor resection. A description of the facility design and equipment are given along with examples from our experience on low-grade gliomas and transsphenoidal surgeries. Our facility based on the twin room concept and uses a 3-T Siemens Trio (Siemens, Erlangen, Germany) scanner. The unit consists of adjacent but independent MRI and operative suites, which are connected by a wide door for ioMRI procedure but are used as conventional MRI and operative units. Rigid head fixation during neurosurgery is achieved with a custom designed 5 pin head-rest which also combines a 4+4 channel head coil. Operation is performed using regular non-MRI compatible equipment and the patient is transferred to the MRI during the procedure using a custom designed floating table. Advanced sequences such as diffusion weighted and diffusion tensor imaging, MR angiography, MR venography, MR spectroscopy can be performed with no changes in the setup and result in image quality comparable to outpatient scans. The intraoperative 3-T ultra high field MRI unit with the twin room concept permits both diagnostic outpatient imaging and image guided surgery in the same setting and is a cost effective solution to afford a highly capable ioMRI system.

Temple-Baraitser syndrome (TBS) is a multisystem developmental disorder characterized by intellectual disability, epilepsy, and hypoplasia or aplasia of the nails of the thumb and great toe. Here we report damaging de novo mutations in KCNH1 (encoding a protein called ether à go-go, EAG1 or KV10.1), a voltage-gated potassium channel that is predominantly expressed in the central nervous system (CNS), in six individuals with TBS. Characterization of the mutant channels in both Xenopus laevis oocytes and human HEK293T cells showed a decreased threshold of activation and delayed deactivation, demonstrating that TBS-associated KCNH1 mutations lead to deleterious gain of function. Consistent with this result, we find that two mothers of children with TBS, who have epilepsy but are otherwise healthy, are low-level (10% and 27%) mosaic carriers of pathogenic KCNH1 mutations. Consistent with recent reports, this finding demonstrates that the etiology of many unresolved CNS disorders, including epilepsies, might be explained by pathogenic mosaic mutations.

Purpose: To investigate refractive and visual outcomes and complications of the Supracor procedure to treat presbyopia. Methods: A total of 123 eyes from 68 presbyopic patients with hyperopia were enrolled in this prospective, nonrandomized, clinical trial. The Supracor procedure was performed using the Technolas excimer laser 217P (Technolas Perfect Vision GmbH). Follow-up eye examinations were performed at postoperative day 1, month 1, and month 6. Results: All 123 surgeries were uneventful. At 6 months postoperatively, uncorrected distance visual acuity was 20/20 or better in 27 (22.0%) eyes and 20/25 or better in 45 (36.6%) eyes. At 6 months postoperatively, 35 (28.5%) eyes lost 1 line and 13 (10.6%) eyes lost 2 lines of corrected distance visual acuity (CDVA). At 6 months postoperatively, uncorrected near visual acuity was 20/20 or better in 95 (77.2%) eyes and 20/25 or better in 110 (89.4%) eyes. At 6 months postoperatively, 6 (4.9%) eyes lost 1 line of corrected near visual acuity. Conclusions: The Supracor presbyopia procedure showed good near visual acuity outcomes over 6 months follow-up but loss of CDVA occurred in 39.1% of eyes. © 2013 Wichtig Editore.

The objective of the study was to evaluate the efficacy and safety of temperature-controlled radiofrequency (RF) tonsil ablation in the treatment of halitosis caused by chronic tonsillitis with caseum. The study method was retrospective. The medical records of 58 patients undergoing temperature-controlled RF tonsil ablation due to chronic tonsillitis with caseum between November 1, 2005 and November 30, 2008 were reviewed. Forty-nine (84.4%) of 58 patients reported complete disappearance of bad breath after the first treatment; five patients (8.6%) reported as having insufficient improvement and four (6.9%) patients had no change. Two patients from "insufficient group" and all four patients from "no change" group agreed to a repeat treatment. After the second session, four (6.9%) patients reported complete disappearance of halitosis with the disappearance of caseum formation. But two patients still suffered from halitosis. One of these patients underwent tonsillectomy, other patient is under our follow-up. Overall, complete elimination of halitosis was accomplished with one session in 49 (84.4%) patients, two sessions in four (6.9%) patients, making a total of 53 (91.3%) patients. Postoperative morbidities included one transient mild bleeding, one secondary bleeding and one mild edema. Temperature-controlled RF tonsil ablation is an effective method for treating halitosis which derived from chronic tonsillitis with caseum. This well-tolerated technique avoids the post-procedure morbidities and discomfort of more invasive surgical modalities currently used. © 2010 Springer-Verlag.
