Background: Nevus sebaceous (NS) is a rare congenital skin lesion affecting approximately 0.3% of all newborns. Although benign, NS lesions can harbor malignant secondary tumors. The published rate of development of these malignant tumors varies. This meta-analysis aimed to identify the rate of malignant and benign secondary neoplasms occurring in NS., Methods: A literature search was conducted using PubMed, Embase, and Web of Science from inception to April 2023. Eligible studies reported incidence or risk of secondary neoplasms in patients with NS. Two independent reviewers screened studies, extracted data, and assessed the quality of included studies. The primary outcome was the pooled incidence of secondary neoplasms. Studies with sample sizes greater than 50 patients were eligible for meta-analysis using the random-effects model., Results: Twenty-eight studies were identified, 22 of which were eligible for meta-analysis. The overall rate of secondary neoplasms was 12.8% (95% confidence interval [Cl], 9.2%-17.6%). The rates of development of malignant and benign tumors were 2.4% (95% CI, 1.4%-4.1%) and 10.3% (95% CI, 7.5%-13.9%), respectively. The rate of development of basal cell carcinoma was 1.7% (95% CI, 0.9%-3.2%), whereas the rate of the development of syringocystadenoma papilliferum was 3.6% (95% CI, 2.5%-5.3%) and that if trichoblastoma was 2.6% (95% CI, 1.7%-3.8%)., Conclusions: Although the rate of development of malignant tumors within a primary NS lesion is low, it is not negligible. Prophylactic early excision remains a viable approach to prevent secondary malignant neoplasms, address cosmetic and functional complications, and preempt the need for complex reconstruction in the future. We propose that resection of NS lesions in childhood remains a reasonable first-line option in the appropriate patient keeping in mind that it may leave an undesirable scar., Competing Interests: Conflicts of interest and sources of funding: The authors declare no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Congenital dorsal curvature of the distal phalanx has been previously described as 'reverse Kirner' or 'ski-jump' deformity. This report describes bilateral occurrence in the thumbs. A 13-year-old male presented with difficulty caring for his thumbnails and in picking up small objects. Examination showed dorsal curvature of the distal phalanges of both thumbs, with greater curvature of the right side. Radiographs showed wedge-shaped epiphyses and dorsal curvature without coronal plane deviation of the distal phalanges. There was objective and subjective decrease in function associated with lateral pinch and tripod grasp. The reported aetiopathogenesis for Kirner deformity cannot explain the observed dorsal curvature. The bilateral nature makes a secondary physeal cause unlikely and suggests an embryologic basis. Due to the noticeable deficits in function, operative intervention may be warranted. Level of Evidence: Level V (Therapeutic).

Background: Management of supracondylar humerus fractures (SCHF) with coexisting median nerve injury is controversial. Although many nerve injuries improve with the reduction and stabilization of the fracture, the speed and completeness of recovery are unclear. This study investigates median nerve recovery time using the serial examination., Methods: A prospectively maintained database of SCHF-related nerve injuries referred to a tertiary hand therapy unit between 2017 and 2021 was interrogated. Factors related to the injury (vascularity, Gartland grade, open vs. closed fracture) and treatment (fixation modality, adequacy, timing of reduction, vascular and nerve intervention, and secondary procedures) were assessed.Primary outcomes were the motor recovery of Medical Research Council (MRC) grade 4 or 5 in flexor pollicis longus or flexor digitorum profundus (index) and detection of the 2.83 Semmes Weinstein monofilament.A retrospective clinical note review of all SCHF presenting during the same period was also conducted., Results: Of 1096 SCHF, 74 (7%) had an associated median nerve palsy. Twenty-one patients [mean age 7 years (SD 1.6)] with SCHF-related median nerve injuries underwent serial examination. Nineteen (90%) were modified Gartland III or IV, and 10 (48%) were pulseless on presentation. The mean follow-up was 324 days.The mean motor recovery time was 120 days (SD 71). Four (27%) and 2 (13%) patients had not achieved MRC grade 4 by 6 months and 2 years, respectively. Only 50% attained MRC grade 5 at 2 years.When compared with closed reduction, those who underwent open reduction recovered motor function 80 days faster (mean 71 vs. 151 d, P =0.03) and sensory function 110 days faster (52 vs. 162, P =0.02). Fewer patients recovered after closed reduction (8 of 10) than open (5 of 5).Modified Gartland grade, vascular status, adequacy of reduction, and secondary surgery were not associated with recovery time., Conclusions: Median nerve recovery seems to occur slower than previously thought, is often incomplete, and is affected by treatment decisions (open vs. closed reduction). Retrospective reporting methods may overestimate median nerve recovery., Level of Evidence: Level III-therapeutic., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare fibrohistiocytic tumor of dermal origin. Six percent of all cases present in children, with a childhood incidence of 1 per million., Methods: This is a retrospective review of all cases of pediatric DFSP managed at a single institution over a 23-year period., Results: Seventeen patients (10 male; mean age, 9.9 years) were managed during the study period. The median follow-up was 29 months. All patients had surgical excision. Three patients required further excision to achieve uninvolved final margins. There were no recurrences observed., Conclusions: Pediatric DFSP should be managed by a soft tissue tumor multidisciplinary team, with experienced pathologists and reconstructive surgeons. Where R0 resections are obtained, patients can experience recurrence-free survival., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2021 Wolters Kluwer Health, Inc.

Introduction: Approximately 2% of the population are anticoagulated and over 50% of over 65-year-olds are prescribed antiplatelet agents. Several systematic reviews have shown the safety of interrupting anticoagulation and antiplatelets for non-emergency surgery, although such reviews excluded upper limb procedures and represents the rationale for this review., Methods: The literature was systematically searched for studies concerning the outcomes of adult hand or wrist surgery on patients receiving anticoagulation or antiplatelet agents in direct comparison to controls (no anticoagulation or antiplatelet agents, or interruption of either). The primary outcome was reoperation for any complication related to postoperative bleeding, within 30 postoperative days., Results: Nine cohort studies (3628 individuals; 3863 operations) were included. Based on very low-quality evidence, anticoagulation did not affect the risk of reoperation for bleeding (RR 2.4 [95% CI 0.1, 57]; 3 studies, n=443) or bruising (RR 2.5 [95% CI 1.0, 6.3]; n=124; I 2 =0%). Based on low quality evidence, antiplatelet agents did not affect the risk of reoperation for bleeding (RR 0.8 [95% CI 0.3, 1.8]; 6 studies, n=1885; I 2 =0%) or bruising (RR 3.2 [95% CI 0.2, 44]; n=571; I 2 =66%). A sensitivity analysis showed that carpal tunnel decompression on patients receiving anticoagulants or antiplatelets appeared to be safe (RR 0.8 [95% CI 0.3, 1.8]; 6 studies, n=2077; I 2 =0%)., Conclusions: Given the sparsity of events (bleeding and bruising) and low-quality of the literature, no firm conclusions can be drawn. The decision to interrupt antiplatelets or anticoagulants should be made jointly with expert physicians and the patient.

The UK hand transplantation programme is hosted by the Department of Plastic and Reconstructive Surgery at Leeds Teaching Hospitals under the leadership of Professor Simon Kay. Since programme launch in 2013, ten procedures in six individuals have been performed involving unilateral or bilateral transplants. The multi-disciplinary team that delivers the programme includes the transplant immunology service. The laboratory experience in programme support is reported here., (© 2019 John Wiley & Sons Ltd.)

This short review will be concerned with the literature that has developed connected with the immunogenetic and tissue compatibility aspects of hand transplantation and will also draw on connected work in the more general area of vascularized composite allotransplantation (VCA) which includes face, abdominal wall uterus and larynx., (© 2019 John Wiley & Sons Ltd.)

Background: We report a variant of paediatric trigger thumb which is locked in extension rather than flexion., Methods: Eleven children with 14 trigger thumbs (three bilateral) locked in extension were reviewed retrospectively over a 12-year period. The number of flexed trigger thumbs encountered over this period was established from the operating room database., Results: All children were treated with release of the A1 pulley. Nine children achieved a full range of motion at the interphalangeal joint. One child with bilateral extended trigger thumbs required bilateral dorsal capsulotomy and another child developed temporary mild triggering in flexion., Conclusions: Approximately 1% of trigger thumbs treated operatively at this institution presented as the extended variant. Trigger thumb locked in extension should be considered in a child presenting with inability to flex the thumb.

Fanconi's anaemia (FA) is a rare, life threatening inherited syndrome. Patients usually present late in the first decade of life with aplastic anaemia or acute myeloid leukaemia. FA children are also at high risk of solid organ tumours, anogenital squamous cancers, and endocrinopathies. These patients can present with unilateral radial abnormalities including thumb duplication. Hand surgeons can help achieve early diagnosis and improved survival in this group by early referral for screening. In a retrospective study of 202 children with radial ray anomalies seen over a 20 year period seven children had FA. Of these seven with FA, four had bilateral thumb hypoplasia and three had unilateral thumb anomalies--two unilateral thumb hypoplasias and one thumb duplication. The three children with unilateral anomalies were diagnosed late, presenting with bone marrow failure. All three have subsequently died following late bone marrow transplants. This study highlights the link between unilateral radial anomalies, including thumb duplication and FA and the importance of early genetic referral for diagnosis and surveillance., (Copyright © 2012 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Desmoid fibromatosis (also known as infantile or aggressive fibromatosis) is a rare soft tissue tumour that is occasionally seen in children. Although histologically benign, its growth pattern is highly aggressive often showing invasion of surrounding musculature and bone. Frequently found in cosmetically sensitive areas, complete excision can present a challenging problem. However, incomplete surgical excision is associated with high recurrence rates and although the disease responds to chemo and radiotherapy, both carry significant risks in young children. The management of four paediatric desmoid fibromatoses occurring in the midface is discussed. The recent and pertinent literature is comprehensively reviewed and an algorithm for the management of paediatric desmoid fibromatoses is proposed., (Copyright © 2011 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Nasal dermoid sinus cysts (NDSCs) are rare congenital anomalies affecting approximately 1 in 30,000 live births. Nasal dermoid sinus cysts are unsightly, prone to infection, and, importantly, may communicate with the central nervous system. Treatment is complete surgical excision. This study retrospectively evaluated management of a large single-center cohort of intracranial NDSCs.Nineteen patients with NDSC were identified from all patients presenting to the Leeds craniofacial service between June 2000 and August 2008. Patient demographics, clinical presentation, preoperative investigations, and surgical procedures undertaken were analyzed.Mean age at presentation and surgery were 6.3 and 7.6 years, respectively. Fifty-three percent were males. Computed tomography (CT) and magnetic resonance imaging (MRI) were performed in 15 and 17 patients, respectively. One patient (5.3%) required local excision only. Eighteen (96.7%) underwent a bicoronal approach, and 13 (68.4%) of these required a craniotomy. The dura was opened in 7 (36.8%) patients. Neither CT nor MRI predicted the presence or absence of intracranial extension in all patients. Positive and negative predictive values for intracranial extension were 85.7% and 50% for CT and were 100% and 50.0% for MRI. Mean follow-up of 4.1 years shows no deep recurrences and 5 (26.3%) were superficial nasal recurrences only.A multidisciplinary approach can achieve good results with infrequent intracranial recurrence. We used a bicoronal approach to facilitate craniotomy when required intraoperatively because imaging is unable to diagnose intracranial extension with sufficient accuracy.

Background: We describe the previously unreported use of isolated limb infusion (ILI) to treat extensive, bilateral plantar warts in a 54-year-old female. The warts had covered the weight-bearing surfaces of both feet for 10 years and had failed to respond to all previous treatments., Methods: A standard ILI technique was used to infuse melphalan and actinomycin D to the left leg. Circulation was maintained for 30 min. The limb was warmed and upon completion of the procedure was markedly hypoxic and acidotic. The contralateral limb was treated 6 months later., Results: At 5 weeks, a partial response with 80% disease clearance was observed. Pain impeded mobilisation until desquamation occurred 6 weeks postoperatively. There was little regrowth at 6 months., Conclusion: Although invasive, ILI may represent a viable treatment option for resistant human papilloma virus-induced warts on the peripheries. Further research into this potential treatment tool is warranted., (Copyright 2009 S. Karger AG, Basel.)

This review evaluates the evidence for a link between smoking and female fertility. Twenty-two primary papers and two reviews were found. All but three indicated a detrimental effect of smoking on reproduction despite varying considerably in their approach, definitions used and populations studied. The strength of association is small but statistically significant and a dose response relationship suggests the theory that smoking is causative. Poor design in particular and the failure to assess confounders weakened many studies and should be addressed in future studies.
