Rate of Benign and Malignant Secondary Tumors Associated With Nevus Sebaceous: A Systematic Review and Meta-Analysis.

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.

Increased risk of complications in lower versus upper limb peripheral intravenous cannulation in children with severe neurological impairment.

BACKGROUND: Obtaining peripheral intravenous catheter (PIVC) access in children with severe neurological impairment (SNI) is often challenging and commonly associated with complications, including dislodgement, phlebitis and extravasation. In severe cases, extravasation injury may lead to tissue necrosis, ulceration and long-term morbidity. The aim of this study was to determine the relative incidence of PIVC complications secondary to lower limb cannulation, compared to upper limb, in children with SNI. METHODS: A single centre, retrospective, observational review was conducted. Patients with SNI, admitted at a tertiary paediatric centre over 6 months between July and December 2022, were included. RESULTS: One-hundred fifty-five PIVC procedures were conducted in 110 children over the study period. Complications were more common in lower limb PIVCs (12/16, 75%) compared to upper limb (58/139, 42%), p = 0.01. CONCLUSION: Upper limb cannulation is preferred in children with SNI.

Radial forearm free flap reconstruction in a 3-month-old patient with undifferentiated pharyngeal sarcoma.

There is minimal information regarding free tissue transfers in very young infants, especially those less than a year old. It is often thought that that age remains a limit to free tissue transfers, with younger patients having smaller vessels, making the operation technically challenging. In this case report, we discuss the youngest and smallest recorded case of a free flap reconstruction. A 3-month-old patient with a malignant parapharyngeal undifferentiated round cell sarcoma underwent a resection and reconstruction with a radial forearm free flap (RFFF). The defect was 35 by 20 by 15 mm, and required a pharyngeal "patch," as opposed to a "tube," reconstruction. The defect was templated, and the RFFF then raised in a standard subfascial fashion, and inset with resorbable sutures. The patient was observed in the ICU postoperatively. The patient was subsequently diagnosed with Stage IV primary undifferentiated sarcoma with regional metastasis and received adjuvant chemotherapy. Fifteen-month follow up revealed no signs of recurrence, full oral intake, a well-reconstructed pharynx on nasoendoscopic examination, and minimal donor site morbidity. This report illustrates several unique adaptations of free flap transfer in infants and adds to the emerging body of evidence that age is not a contraindication for head and neck reconstruction.

Median Nerve Palsy in Pediatric Supracondylar Humerus Fractures Recovers Faster With Open Than Closed Reduction.

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.

Pre-natal and post-natal diagnosis of congenital upper limb differences: The first 3 years of the Australian Hand Difference Register.

AIMS: Children with a congenital upper limb difference (CoULD) are a diverse group who often require multidisciplinary care and long-term support for functional and social impacts. The Australian Hand Difference Register (AHDR) provides a national database of children born with a CoULD and aims to facilitate research and improve health care for affected children. Using data from the first 3 years of its operation, we analysed the demographic and clinical features of participating families, including type of CoULDs and the frequency of pre-natal and syndromic diagnoses. METHODS: Families were recruited from tertiary plastic surgery, orthopaedic and genetics clinics, as well as by self-referral. Hand differences were classified by the consulting physician according to the Oberg-Manske-Tonkin classification system. Primary carers were invited to complete an online questionnaire covering demographic information, pregnancy and newborn outcomes and diagnostic details. RESULTS: Between August 2017 and September 2020, 822 families consented and 320 questionnaires were reviewed. CoULDs were detected pre-natally in 66 (20.6%) and post-natally in 248 children (77.5%); data for 6 (1.9%) children were missing. The most common CoULDs were radial polydactyly, symbrachydactyly with ectodermal elements and radial longitudinal deficiency, hypoplastic thumb. Twenty-seven children (8.4%) had an associated syndrome, 7 diagnosed pre-natally and 19 post-natally; the most common were VACTERL association, Poland anomaly, Holt-Oram and ectrodactyly-ectodermal dysplasia-clefting syndromes. CONCLUSIONS: The AHDR is a valuable resource for understanding the relative frequencies of CoULDs. Participation will assist future research into the diagnostic journeys of children with CoULDs, including risk factors, diagnosis and psychosocial impacts.

Diagnostic and Management Considerations in Pediatric Dermatofibrosarcoma Protuberans.

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.

The histocompatibility and immunogenetics of hand transplantation.

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.

The Leeds hand transplant programme: Review of the laboratory management of the first six cases.

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.

Bilateral Dorsal Nail Curvature of the Thumb Distal Phalanx - A Case Report.

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).

Synchronous circular frame stabilisation and microsurgical soft tissue reconstruction for open lower limb fractures-A cost analysis and description of the surgical technique.

INTRODUCTION: Current surgical paradigms for ortho-plastic management of IIIB open tibial fractures make compromises. Often, definitive circular frame stabilisation is delayed until the soft tissue envelope is secure to allow access for further soft tissue reconstruction if required. This delay has potential clinical and cost implications. A previous study showed acute circular frame stabilisation performed concurrently or before soft tissue reconstruction was feasible without additional soft tissue reconstruction problems. This study examines potential resource savings using this approach. METHODS: All open tibial fractures managed by circular fixator and microsurgical soft tissue reconstruction between April 2015 and June 2019 were identified from a prospectively maintained database. Those receiving circular frame stabilisation with synchronous microsurgical soft tissue reconstruction were considered cases; those in whom the frame stabilisation was delayed were controls. Cost data were derived from the Patient Level Information and Costing System. Salvage cases and those with incomplete treatment were excluded. RESULTS: Nine cases and 25 controls were evaluated. No statistically significant difference was observed between groups in terms of age, sex, injury severity score, time to debridement, time to coverage, length of follow up, or time to union. Median length of stay was 13.3 and 19.7 days for cases and controls respectively (p<0.01). Cases required fewer procedures (2.3) compared to controls (4.5) (p<0.001). The cost of care was less for cases (£25,527) than controls (£32,952) (p <0.05). No cases returned to theatre with flap failure or flap compromise. Complications were similar between groups. CONCLUSION: In suitable patients, synchronous circular frame stabilisation and microsurgical soft tissue reconstruction is a safe, clinically effective, and cost-saving option.

The incidence and spectrum of congenital hand differences in patients with Fanconi anaemia: analysis of 48 patients.

We analysed the spectrum of congenital hand differences in a cohort of patients with Fanconi anaemia (FA). Data of 48 FA patients at the National Cancer Institute were reviewed focusing on age at diagnosis, type and severity of limb difference and any potential association with other known clinical anomalies that are part of the FA phenotype, specifically VACTERL-H and PHENOS. Twenty-eight patients had an upper limb difference, which always included thumb hypoplasia. Twenty-three patients had bilateral upper limb differences, including varying combinations and severities of thumb hypoplasia, radial dysplasia and thumb duplication. Patients with a limb difference were diagnosed at a younger age (<2 years: 15/28 with limb anomaly versus 4/20 without a limb anomaly). However, 7/28 with limb anomalies, usually thumb hypoplasia, were not diagnosed until after 6 years of age. This study demonstrates the broad spectrum of radial ray anomalies within the FA phenotype along with the possibility of either unilateral or bilateral upper limb differences and adds further merit to consideration of screening for FA in all cases of radial ray anomaly.Level of evidence: II.

Wrist fusion using an induced membrane technique for forearm salvage in a patient with an infected open injury with segmental bone loss: A case report.

This case report describes the management of a 27-year-old male who, after a quadbike accident, presented with an open, infected, segmental both bone forearm injury with significant bone and soft tissue loss including the radio-carpal joint. Limb salvage was accomplished in the form of a single bone forearm fusion utilising Masquelet's two-stage induced membrane technique to reconstruct the segmental bone defect. The patient proceeded to uneventful bony union by 6 months and returned to driving and riding a quadbike. Despite significant deep infection, successful salvage was achieved using the induced membrane technique. Critical to success was aggressive, repeated debridement alongside restoration of vascular supply and reconstruction of soft tissue defects. We highlight the multidisciplinary approach to management including relevant specialists with a particular interest in limb reconstruction.

Surgical correction of midline nasal dermoid sinus cysts.

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.

Hand and wrist surgery on anticoagulants and antiplatelets: A systematic review and meta-analysis.

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; I2=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; I2=0%) or bruising (RR 3.2 [95% CI 0.2, 44]; n=571; I2=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; I2=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. Registration: PROSPERO ID CRD42018087755.

Isolated limb infusion as a novel treatment for extensive plantar warts.

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.

The "Trigger" Thumb Locked in Extension - An Unusual Presentation of a Common Paediatric Condition.

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.

Smoking and female fecundity: the effect and importance of study design.

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.

A Previously Discounted Flap Now Reconsidered: MatriDerm and Split-Thickness Skin Grafting for Tendon Cover Following Dorsalis Pedis Fasciocutaneous Flap in Lower Limb Trauma.

OBJECTIVE: The dorsalis pedis flap has reliable vascularity; however, its use is limited by reports of donor site morbidity including infection, delayed healing, exposure of tendons, and later contractures. The purpose of this study was to demonstrate its continued role in lower limb trauma when the donor site is reconstructed with MatriDerm to avoid complications. METHODS: A 65-year-old man presented with a displaced, Gustilo 3b open transverse fracture of his left distal fibula. He had a 2 cm(2) open wound over his lateral malleolus. RESULTS: Following review of possible local options, a dorsalis pedis fasciocutaneous flap was deemed best for coverage, and the donor site was closed with 1-mm MatriDerm dermal matrix and a 6/1000 inch split-thickness skin graft (STSG) in a single stage. Three months postoperatively, the foot had excellent function and cosmesis, with toes in a neutral position and a full range of movement. CONCLUSIONS: The dorsalis pedis flap is a valuable reconstructive option for defects of the foot and ankle. Its major limitation donor site morbidity can be overcome by the additional application of a dermal substitute such as MatriDerm under the STSG.
