Background Reconstruction of thumb tip, while providing a durable and sensate flap, is a challenging task. It is important as thumb accounts for 50% of hand functions. Options for coverage are: healing by secondary intention, local/regional flaps, microsurgical toe wraparound flap, etc. First dorsal metacarpal artery (FDMA) flap is one regional flap that has been used for thumb cover, usually for defects till interphalangeal joint or just distal to it. We present our case series for FDMA flap and its variations for thumb reconstruction. We also report reverse FDMA flap cover for reconstruction of defects over distal phalanx of thumb. Methods The procedure was performed in patients with partial loss of thumb soft tissue in 16 patients presenting during 2017 to 2020. The FDMA flap was performed according to the standard technique. In case after “planning in reverse,” it was seen that the reach of FDMA flap was insufficient, reverse FDMA flap was done. Physiotherapy for index finger and thumb was started on day 10. Patient satisfaction, in terms of cosmesis and function was recorded (graded as poor, good, and very good). Static two-point discrimination (2-PD) was assessed at 6 months'' follow-up. Patients were followed up for 6 months. Results The operative time was 1 to 2 hours. Out of total 16 cases, 8 patients underwent racquet-shaped (intact skin paddle) FDMA flap. Islanded flap was performed in five and reverse FDMA flap in three. Twelve patients had uneventful recovery and four patients (three islanded and one reverse FDMA) had partial skin loss. Static 2-PD was assessed at the 6 months postoperative period. Conclusion FDMA flap is a useful regional flap for thumb reconstruction. It provides good supple, durable, and sensate cover. The reverse FDMA flap that increases the pedicle length can be used for more distal defects, where conventional FDMA flap is doubtful. 相似文献

Background: This study was aimed to describe incidence, trends, and survival of oral and pharyngeal cancers in Khon Kaen, the province situated in the northeast of Thai-land. Methods: Data on oral and pharyngeal cancer cases diagnosed during 1985 - 2001 were retrieved from the population-based cancer registry of Khon Kaen. The final status of the patients was verified by database linkage and follow-up using postcards. Results: Of 1,038 cases, 62.6% were female and 37.4% were male, with a mean age of 63 years. The age-standardized incidence rate (ASR) in females (6.2 per 100 000; 95%CI 5.7-6.7) was significantly higher than in males (3.9 per 100 000; 95%CI 3.5-4.4). Annual percent changes in ASR were 1.7 in females (p<0.05), but 1.2 in males. Lip and buccal cancers were the most common sites respectively; however, the incidence of tongue cancer was increasing in the last period. Eighty five percent of all cases were diagnosed in advanced stage (stage III and IV). The overall five-year relative survival was 43.1%. We found stage distribution and survival did not change during the study period. Conclusion: The considerably high incidence in female suggests a need for research on specific risk factors. Moreover, attempts should be made to detect oral cancers earlier in order to improve the outcomes of cancer control. 相似文献

Purpose
Our laboratory has developed and implanted a novel bioengineered internal anal sphincter (IAS) to treat anal incontinence. Fibroblast growth factor-2 (FGF-2) has been used in mice; however, the optimal growth factor for successful IAS implantation is unclear. This study compares several growth factors in order to optimize IAS viability and functionality. 相似文献6.

Background: Liver cancer is the most frequent cancer among Thais especially people in northeastern Thailand, but there has as yet been no assessment of trend. The data of all cancers in Khon Kaen can be retrieved from data base of the Khon Kaen Cancer Registry (KKCR) which was established in 1984. Objective: To assess the incidence trend of hepatocellular carcinoma in Khon Kaen, Thailand, between 1990 and 2009. Methods: Population-based cases of liver cancer registered between 1985 and 2009 were retrieved from the KKCR data base and cases with diagnosis of hepatocellular carcinoma (HCC) with the coding C22.0 according to ICD-O were selected. Incidence trends were calculated using the Jointpoint analysis. Results: There were 7,859 cases of HCC during the study period. Males were affected two times more frequently than females. The most common age group of cases was 50 and 69 years (60.3%). Most patients were diagnosed based on radiology imaging (40.6%) while the morphology verification was 7%. The age-standardized rates (ASR) were 13.1 to 49.8 per 100,000 among males and 4.8 to 38.4 per 100,000 among females depending on year of diagnosis since 1985. Remarkably, the ASRs were clearly low during first few years of starting the registration. The overall ASRs of HCC were 30.3 per 100,000 in males (95% CI: 25.9 to 34.6) and 13.1 per 100,000 (95% CI: 10.4 to 15.8) in females. During 1990-2009, the trends in incidences have been decreasing significantly with the annual percent change (APC) of 6.2% per year (95% CI: –7.6 to –4.8) in males and by 6.5% per year in females (95% CI: –8.4 to –4.9). Conclusions: The incidence trends have been decreasing in both sexes. The recent decline in incidence may represent a falling risk. 相似文献

Fine needle aspiration (FNA) cytology is well accepted as a safe, reliable, minimal invasive and cost-effective method for diagnosis of salivary gland lesions. This study evaluated the accuracy and diagnostic performance of FNA cytology in Thailand. A consecutive series of 290 samples from 246 patients during January 2001-December 2009 were evaluated from the archive of the Anatomical Pathology Department of our institution and 133 specimens were verified by histopathologic diagnoses, obtained with material from surgical excision or biopsy. Cytologic diagnoses classified as unsatisfactory, benign, suspicious for malignancy and malignant were compared with the histopathological findings. Among the 133 satisfactory specimens, the anatomic sites were 70 (52.6%) parotid glands and 63 (47.4 %) submandibular glands. FNA cytological diagnoses showed benign lesions in 119 cases (89.5 %), suspicious for malignancy in 3 cases (2.2 %) and malignant in 11 cases (8.3%). From the subsequent histopathologic diagnoses, 3/133 cases of benign cytology turned out to be malignant lesions, the false negative rate being 2.2 % and 1/133 case of malignant cytology turned out to be a benign lesion, giving a false positive rate was 0.8%. The overall accuracy, sensitivity, specificity, positive predictive value and negative predictive value were 97.0% (95% CI, 70.6%-99.4%), 81.3% (95% CI, 54.4%-96.0%), 99.1% (95% CI, 95.4%-100%), 92.9% (95% CI, 66.1%-99.8), 97.5% (95% CI, 92.8%-99.5%), respectively. This study indicated that FNA cytology of salivary gland is a reliable and highly accurate diagnostic method for diagnosis of salivary gland lesions. It not only provides preoperative diagnosis for therapeutic management but also can prevent unnecessary surgery. 相似文献
