Overview of Extremity Replantation in Taiwan by the National Health Insurance Database from 1996 to 2000

This study is the first epidemiological report of limb replantation surgery concerning the whole population of Taiwan. The materials are based on the 1:20-sampled National Healthcare Insurance (NHI) Research Database from 1996 to 2000.368 and 236 patients were extracted from the hospitalization datasets, based on the ICD procedure codes and the detailed medical orders respectively. 77.1% and 14.0% of cases received one-and two-digital replantation. The average operating times are 3.9, 5.5, 7.9, and 10.2 hours from one- to four- digit replantations. Average length of hospital stay, surgical and total fees were 12.5 days,

Nipple inversion can cause aesthetic, functional and psychological problems, especially for affected woman. Many patients are distressed by nipple appearance and have problems of breastfeeding. Irritation and inflammation are not uncommon by inverted nipple. They were divided into three groups by the system of grading. The grade was made by preoperative evaluation of severity of inversion and was conformed by the surgical finding. Many techniques have been introduced for correction of this anomaly by many authors, such as purse string suture technique, nipple piercing or dermal flap. We develop a new method as a modified dermal flap for correction of nipple inversion with ”X-wing dermal flap” to achieve a sure and long-lasting result. Between May 2006 and August 2006, total 23 nipples of 13 patients received this method to correct Grade Ⅱ to Ⅲ nipple inversion. Male (N=1) and female (N=12) are included in this study. The X-wing dermal flap method provides an easy and reliable procedure with minimal complication, fast recovery and good result for both patient and surgeon.

Reconstruction of Fingertip Amputation by Composite Graft with Abdominal Pocket Principle

We present the application of ”meta-search engine” in evidence-based medicine (EBM) by online cluster analysis of PubMed literature. The methodology would be especially beneficial to ”evidence-based plastic surgery”. In addition to the initial aim of splitting the diverse documents into organized relevant and homogeneous document groups (clusters), knowledge discovery of new or neglected sub-topics and selection of key phrases based on information technology are stressed. PubMed query on ”breast reconstruction” in the recent 2 years yielded 496 articles, which was processed by the online tool. Nine larger clusters comprise of about 70% of the literature, which is ”skin-sparing”, ”tissue expander”, ”DIEP flap”, ”nipple”, ”latissimus dorsi”, ”perforator flap”, ”TRAM flap”, and ”internal mammary vessels”. The details of the knowledge structure were further explored, and a new finding of the ”Chinese women” cluster was described.

The Dorsal Digital Adipofascial Flap for Fingertip Defects-Cases Report and Evolving Thoughts

Triamcinolone acetonide suspension is a long acting corticosteroid product for intra-lesional injection of hemangiomas in our series. There were very few cases reported about triamcinolone induced anaphylactic reaction previously. From April 2001 to April 2005, there are 277 hemangioma patients who received intra-lesional triamcinolone injection in our series. 7 of them suffered from anaphylactic reaction immediately after the treatment. They were recovered smoothly after resuscitation with intramuscular epinephrine injection and oxygen supply. We presented these seven patients about their signs and symptoms of anaphylaxis, treatment protocols, and their following alternative treatment of hemangiomas, and we also reviewed the proposed mechanisms of corticosteroid-associated hypersensitivity reactions in this study.
