RESUMEN
Purpose: The aim of this study was to evaluate the cosmetic outcomes of native nail plate (NP) replacement as a free graft and using an artificial NP in reconstruction of the fingertip injuries. Methods: Two prospective cohorts of patients with fingertip injuries and avulsed NPs were evaluated. In group 1 (54 patients with 61 fingertip injuries), the native NP was available and suitable for placement under the proximal nail fold. In group 2 (31 patients with 32 fingertip injuries), the native NP was either lost or highly damaged and it was not suitable for use. In this group, an artificial NP was used. The final cosmetic outcomes of regrown NPs were evaluated at a minimum of 4 months after surgery using the Oxford Finger Nail Appearance Score. Results: "Trapped in a door" was the most common cause of injury in pediatric patients, whereas work-related injuries were the most common cause of injury in adults. The difference between the mean appearance scores of the two groups favored group 1 (native NP). There was a negative correlation between the patient age and appearance scores, irrespective of the treatment group. The presence of a distal phalanx fracture adversely affected the appearance scores. Conclusions: Replacing the native NP for splinting in fingertip injuries is advantageous. Fingertip injuries in pediatric patients and fingertip injuries without distal phalanx fractures achieved better cosmesis scores. Type of study/level of evidence: Therapeutic III.
RESUMEN
BACKGROUND: Esophageal cancer is often diagnosed in the last stages where the chance of patient's survival is very low. The aim of this systematic review was presentation of valid estimation of survival in patients with esophageal cancer in different regions of Iran. METHODS: A SYSTEMATIC REVIEW WAS CARRIED OUT BASED ON THE RELIABLE DOMESTIC MEDICAL DATABASES INCLUDING: SID, Magiran, Irandoc and Iranmedex as well as reliable foreign databases like PubMed and Scopus using "Cancer", "Esophagus", "survival" "Neoplasms" and "Longevity" as keywords. Then all the reviewed articles and dissertations which met the entry criteria were analyzed. The data were analyzed by using meta-analysis method (random model) and by means of STATA software application version 11.1. RESULTS: In 18 studies the total numbers of 2932 people were analyzed. The one year survival rate in Iran is estimated at 47 percent (95% CI: 34-61) and the five year survival rate is estimated at 12% (95% CI: 8-16). The two, three and four year survival rates were 31% (95% CI: 18-44), 22% (95% CI: 13-31) and 21% (95% CI: 4-38), respectively. CONCLUSION: According to the findings one year survival rate for esophageal cancer in Iran is almost four times higher than its five year survival rate. Moreover the five year survival rate in Iran is less than many other countries.
