“…The main causes of nail bed deformity are tight closure (tension), secondary intention, and bone support loss. [9][10][11][12][13] This too was overcome by our new technique. In addition, we managed to achieve patient's satisfaction in the late postoperative period because the finger's natural shape had been restored (with a more curved shape and not flat fingertip).…”

The main aim of the treatment in fingertip amputations is to establish the functional and aesthetic construction of the fingertip. The aim of this study is to discuss how to use purse-string suture as a complementary technique accompanying conventional flaps repair in fingertip amputation. Fifty-four patients with fingertip amputations on the nail bed referred to our center for fingertip reconstruction. From which 41 patients who had at least one-third of their nail remained (to preserve the nail) were chosen to undergo this new technique. Patient's satisfaction of the achieved functional results (in case of pain and motion) was as follows: 32 responded excellent, 8 good, and 1 fair. Also, patient's satisfaction of the achieved aesthetic results were Excellent = 7 and Good = 2 in females (n = 9) and Excellent = 19, Good = 7 and Fair = 6 in males (n = 32). 93% (38 patients) of the patients had two-point discriminationof less than 3 mm. No flap necrosis was observed in this study. The flap donor site was covered by primary closure (in 24 cases), secondary intention (in 11 cases), and skin graft (in 6 cases). The nail and finger contour are important for achieving a satisfying aesthetic and functional result. We believe that this new complementary technique could be an easy way for reaching this end. It is recommended that this technique be applied to all fingertip injuries to preserve the nail.

“…As a nail bed beneath the nail is supplied by the nerve, the branches of the digital nerve, injuries to the branches, and its proximal trunk may influence nail growth (Ross and Ward, 1987;Zook et al, 1980). That may be why an innervated nail is better than a non-innervated one.…”

We describe reconstruction of a nail unit defect in the finger using a free composite flap taken from the great toe, comparing the outcome in patients in whom neurorrhaphy between the dorsal digital nerve of the great toe and the dorsal branch of the proper digital nerve of the injured finger was performed to those in which no nerve repair was made. From January 2002 to March 2009, 47 patients with traumatic fingernail defects were treated. Twenty-two patients before February 2005 had no nerve repair and subsequently 25 patients had nerve repair. The mean size of the germinal matrix and sterile matrix defects was 9 × 8 mm, and the mean size of the nail bed flaps was 9 × 9 mm. The mean length of the arteries used for the flap was 2.2 cm. Outcomes were rated. In the nerve repair group, full flap survival was achieved in 24 patients. At the mean follow-up period of 25 months, there were 12 excellent, seven very good, four good, and two fair results. In the comparison group without nerve repair, there were seven excellent, four very good, four good, five fair, and two poor results. Donor site morbidities were similar in both groups. The use of a free composite flap taken from the great toe is a useful technique for reconstructing nail unit defects in the finger. Innervated nail flap reconstructions tended to show better outcomes than those in which no nerve repair was performed. There is no difference in function or donor site between those in whom the nerve was repaired compared with those in whom it was not repaired.

“…Newborn nails are formed during the second trimester of pregnancy [67], grow continuously, and persist after birth, thus providing an opportunity to assess in utero drug exposure. In contrast, neonate hair growth starts during the third trimester, occurs in cycles and hair is generally lost within 8-12 weeks after birth [68].…”

Nail analysis for the detection of drugs of abuse and pharmaceuticals: a review

et al. 2014

View full text Add to dashboard Cite

Nails can stably accumulate substances for long periods of time, thus providing retrospective information regarding drugs of abuse and pharmaceutical use. Nails have several advantages over the conventional matrices, such as blood and urine, including a longer detection window (months to years), non-invasive sample collection, and easy storage and transport. These aspects make nails a very interesting matrix for forensic and clinical toxicology. Because of the low concentrations of drugs of abuse and pharmaceuticals present in nails and the complexity of the keratinized matrix, analytical methods need to be more sensitive, and sample preparation is crucial. This review summarizes the literature regarding the detection and quantification of drugs of abuse and pharmaceuticals in nails, as well as the employed pre-analytical and analytical techniques. Additionally, the applications of nail analysis are reviewed. Finally, an overview of the challenges of nail analysis is provided, and guidelines for future research are proposed.
