Onychogryphosis is an acquired nail plate change. It often affects the toenail and is characterized by an opaque, yellow-brownish nail plate that is distorted, grossly thickened, elongated, and partly curved resembling a ram's horn. Tuberous sclerosis complex is a multisystem disorder associated with high rates of mental retardation, autism, cognitive impairment, behavioral problems, or seizures. Nail disease can also be associated, which is a concern to patients due to pain and nail distortion. We reported a typical tuberous sclerosis complex patient with distinctive clinical features of a ram's horn nails, which presented a great challenge to surgical treatment and nail restoration.
- Lower limbs deformities in patients with McCune-Albright syndrome: Tomography and treatment. [Journal Article]
- AJAfr J Paediatr Surg 2016 Jul-Sep; 13(3):125-30
- CONCLUSIONS: Tendency to progressive unilateral lower limb deformity in patients with MAS is usually associated with thinning and expansion of the cortex and distortion of the normal lower limb integrity secondary to repetitive micro-fractures. The latter is a situation which warrants surgical treatment to re-align the deformity and to preserve function. Prophylactic intramedullary nailing via the application of locking nails to ensure stabilisation of the femoral neck was found to be effective. However, nevertheless, the mosaic nature of MAS means any cell, tissue and organ in any site of the body could be affected to varying degrees. The clinical manifestations are a diversity of the disorder ranging from mild clinical signs to severe life-threatening disease.

The success of surgical approaches to ingrown toenails depends on the extraction (either partial or total) of the nail matrix. The identification of the nail matrix in specimens taken from ingrown toenails is not always easy because of the fragmentation of the biopsies, difficulties in matrix orientations and the heavy inflammatory infiltrate. In biopsies taken from polydactyly surgeries, the matrix shows a peculiar pattern of expression of the CD10 and CD34 markers that differs from the one shown by the lateral nail fold. We investigated whether such a pattern was also found in biopsies from ingrown toenails, which can be greatly distorted through inflammation and fibrosis. We examined 15 biopsies from cases of ingrown toenails at different clinical stages. We performed routine Hematoxylin-Eosin studies, as well as immunohistochemical studies with CD10, CD34, HMB-45 and Melan-A. The morphologic changes in all cases were typical of those found in ingrown toenails and their intensities correlated with the clinical stages. Matrical keratinization was identified in all of the biopsies. Morphologic features that are compatible with the lateral nail fold were also seen in seven of the 15 biopsies. In five cases, an intermediate area of transition between matrix and lateral nail folds was heavily distorted by inflammatory changes. Melanocytic markers showed scattered intra-epidermal cells in all but one case. HMB-45 and Melan-A were equally good in demonstrating the melanocytic population. We concluded that the expression of CD10 and CD34 in cases of ingrown toenails is preserved and it follows the pattern described in nails from polydactyly. Therefore, both markers can be useful in fragmented specimens taken from surgeries for ingrown toenails, in order to confirm the removal of the nail matrix.

Certain arthropathies can distort the normal acromiohumeral relationship and make traditional anterolateral access to the proximal humerus for nailing difficult or impossible. This article presents a case of bilateral antegrade humeral nailing in which the Neviaser portal approach was used for humeral shaft fractures in a patient with distorted shoulder anatomy secondary to severe cuff tear arthropathy and rheumatoid arthritis. Based on a literature review, extending the traditional superomedial (Neviaser) portal to the shoulder to perform humeral nailing has never been described clinically. An 85-year-old woman with rheumatoid arthritis and bilateral cuff tear arthropathy presented after a mechanical fall from standing height with bilateral acute humeral shaft fractures. Preoperative fluoroscopy confirmed the inability to access the traditional starting point with an anterolateral approach due to a shield acromion resulting from cuff tear arthropathy and rheumatoid arthritis. Bilateral locked antegrade humeral nails were successfully placed through a 3-cm incision just off the medial border of the acromion and directly posterior to the acromioclavicular joint (the extended Neviaser portal approach). Postoperatively, the patient demonstrated early evidence of clinical and radiographic union. She was able to return to her preinjury function level, with an active range of motion comparable with her baseline. The Neviaser portal approach to antegrade humeral nailing is an effective solution to diaphyseal humeral fractures when access to the traditional anterolateral proximal humeral starting port is not possible due to distorted shoulder anatomy.

The brain of a 5-year-old boy with Schinzel-Giedion syndrome displayed a cobblestone appearance of orbital and lateral aspects of frontal lobes due to widespread glioneuronal meningeal heterotopia. Meningeal heterotopia consisted of scattered neurons, neurofilament positive axons, and myelinated fibers accompanied by striking astrocytic gliosis. The underlying cortex showed gaps in the pial basal lamina, distorted neuronal layering, and focal polymicrogyria. The number of capillaries appeared increased throughout the brain. Mild hydrocephalus was associated with a slight atrophy of corpus callosum as well as villous hyperplasia and marked stromal degeneration of the choroid plexus. Our findings suggest that Schinzel-Giedion syndrome may represent One more entity within enlarging spectrum of lissencephalic cortical dysplasia syndromes.
- Correction of pincer-nail deformities with autograft or homograft dermis: modified surgical technique. [Journal Article]

The pincer-nail deformity is characterized by an excessively curved and distorted nail across the transverse dimension. Forty-nine sides (paronychial folds) were dissected off the distal phalanx periosteum with scissors and/or a small elevator. The dermis was placed between the paronychial fold and the plalanx to flatten the germinal and sterile matrix. Direct comparison of autograft dermis to homograft dermis did not show any significant differences in postcorrection appearance of the nail or relief of symptoms. Surgical time averaged 22 minutes less in those patients having reconstruction on both sides of one nail with homograft dermis.

Ellis van Creveld Syndrome (EVCs) is a chondroectodermal dysplasia. Its clinical picture includes a meso-acromielic limb dwarfism with normal spine, involvement of the teeth, hair and nails, polydactyly of the hands and feet and heart malformations. Ultrasonography compared with histology were used in the present study to evaluate neo-natal ultrasonographic hip development and acetabular hysto-morphology in EVCs. A flat and abnormal acetabulum with small beta angles and non measurable alfa angles were detected at repeated ultrasonographic evaluations at birth and at four months, with irregular echoes spiking from the inner part of the sockets; the acetabular cavities contained large early ossified proximal femoral epiphyses. Histology was obtained from phal-angeal growth plates of a surgically removed extradigit, stained with alcian blue/PAS and E.E.. The growth plates showed a distorted anatomy with irregular column formation and abnormal distribution of the hypetrophic cells. Ultrasound morphology corresponded to the altered growth plates seen at histology. Early detection of an abnormally early developed proximal femoral ossification centre could be considered a diagnostic feature of the syndrome especially when present in the prenatal period.

Cutaneous fungal infections occur frequently in the adolescent population, and are second only to acne in generating skin-related adolescent anguish. Though superficial fungal infections of the skin are rarely life-threatening, they can cause significant worrisome cutaneous findings (e.g., white spots from pityriasis versicolor, distorted nails from onychomycosis). Such changes are particularly threatening to an adolescent who wants to be just like everybody else. This article focuses on several of the more common cutaneous fungal infections in adolescence, including pityrosporum (tinea) versicolor and dermatophyte infections of the feet, groin, skin, and nails. The prevalence of each disease is discussed, along with its clinical presentation, differential diagnosis, and methods of treatment.
