Ingrown Toenails

Background: Severely incurved toenails are accompanied by deformity of the toenail growth plate. In such a condition, partial removal of the nail and nail bed and simple unfolding of the nail itself frequently result in the recurrence of symptoms. We sought to design and develop a new technique for the treatment of incurved toenail with growth plate deformity and to report the results of treating this disease entity. Methods: Forty consecutive patients (52 cases) underwent treatment of symptomatic incurved toenails with a new technique named matrixplasty. The mean ± SD patient age was 40.3 ± 18.9 years. Last follow-up was at a mean ± SD of 18.0 ± 1.3 months. An American Orthopedic Foot and Ankle Society (AOFAS) forefoot hallux score was assigned, and patients were evaluated before treatment and at last follow-up. Patient satisfaction and the recurrence rate of the deformity were evaluated. For evaluation of improvement in toenail shape, the center to edge angle of the toenail was measured before treatment and at last follow-up. The complication rate was also evaluated. Results: All of the ingrown toenails healed, and the nail deformities were corrected within 3 weeks after the procedure. None of the incurved toenails had recurred by last follow-up. The mean pretreatment AOFAS forefoot hallux score was 72.9, and it improved to 99.6 by last follow-up (P < .001). Every patient was very satisfied or satisfied with the results of treatment. The mean ± SD center to edge angle of the toenail improved from 53.3° ± 9.5° to 15.3° ± 5.2° by last follow-up (P < .001). Minor paronychia, which was managed with local wound dressing and oral antibiotics, was identified in four cases. No other complication was identified. Conclusions: Matrixplasty showed excellent clinical results in the treatment of severe incurved toenail, and this newly developed procedure showed improvement of the deformed toenail and its growth plate.

Abstract This paper evaluates a new technique that can lead to excision of pilonidal sinus with less healing time and low recurrence rate. A prospective randomized double-blind controlled study on 142 patients with pilonidal sinus conducted during the period from September 2008 to March 2012. The patients were prospectively randomized to be operated with one of four surgical techniques, excision and primary closure, or excision after using hydrogen peroxide (H202) and primary closure, or excision without closure, or excision after injection of H202 without closure. The main outcome measures were the healing time and the recurrence rate. Out of 142 patients, 118 patients were males (83%), and 24 were females (17%). The mean age was 24.5 years. The recurrence rate in patients treated with excision after injection of H202 without closure was the lowest (1.8%) with P-value < 0.005, and the mean duration of healing was 30.7 days with P-value < 0.005. We recommend using excision after injection of H202 without closure in management of PNS. Injection of H202 into the pilonidal tracts can give a precise delineation of the affected tracts, which can be excised with minimal amount of surrounding normal tissues and hence lead to a quicker recovery and low recurrence rate.

AbstractResults of an experimental X-ray study on 96 synthetic glasses show that the 2θ positions of glass diffraction maxima have an inverse relation to SiO2 concentration in silicate glasses. This relationship is the basis of a new technique for semiquantitative determinations of SiOa in silicate materials by X-ray diffraction methods. Samples to be examined are fused and the resulting glass scanned from 12 to 40° 2θ using CiiKa radiation. The mean 2θ position of the diffraction maximum is a measure of the SiOs content of the glass. Calibration curves for both weight and molecular percent SiO2 vs. 2θ are presented in this report. The technique requires only small, unweighed amounts of sample for analysis ; it is simple, rapid, and utilizes standard diffraction equipment without modification. Its accuracy, at present, allows SiOa determinations to within ±1 to 4% of the actual concentration.

A New Technique

A new instrument for measuring the velocities of particles suspended in a flowing fluid is described. The instrument is linear and is therefore capable of measuring the mean velocity in a fluctuating stream, even when these fluctuations are greater than this mean value. This particular instrument was developed for free convection work where the velocities to be measured were in the range + k 0.2 in./sec to − 0.2 in./sec, but there seems to be no reason why this range could not be considerably extended.

Abstract The article contains a new technique to estimate the mean of the variate of the interest of the finite population with the help of two auxiliary variates. The technique complies well with the stratified population in which each strata proportion is predicted by taking an initial sample called the first phase sample. When the first phase sample is taken, a second sample is taken from the first sample which is called the second phase sample which is used to estimate the mean of the variate of the interest. In our study, we have considered the population which has two correlated auxiliary variates that pass almost through the origin. In such a situation ratio estimation technique and product estimation technique that provides improved estimates of the mean of the variate of the interest. Our technique considers a ratio-product type exponential estimator of which we have established efficiency theoretically as well as empirically.

Deformities of burn scars in the chin and upper neck are a tragedy for patients and pose a great challenge to plastic surgeons due to limited available methods for the reconstruction of three-dimensional appearance. In this paper, we present a new technique for the correction of cervicomental angle with a dermal fat flap. Fourteen patients ages 18 to 24-year-old with extensive neck deformities were enrolled in the study. During the operation, first, we deepithelialized a triangular scar area in the upper neck, then created a dermal fat flap and flip it up to the chin, restoring the chin shape and volume, after that for subsequent reconstruction of cervicomental angle, after releasing skin from lateral sides of the triangle defect, we approximated the AB and AC line to the upper edge of the defect by V-Y advancement. The remaining defect is covered with a full-thickness skin graft. In all cases, the chins were reshaped with a dermal fat flap. The mean cervicomental angle was 144+14.6° preoperatively, which was reduced to 108.9+6.15° postoperatively. The neck and chin were preserved with better contours. This is a new technique that has never been described before in the literature, and it is innovative compared to the traditional techniques. Good cosmetic outcomes make this technique preferable for all burn neck deformities with an obtunded cervicomental angle.
