Subungual Exostosis Presenting as a Pyogenic Granuloma-like Lesion with Reactive Myofibroblastic Proliferation in Two Young Women.

Subungual exostosis (SE) is a well-recognised benign proliferation of the distal phalanx most often seen in young adults and affecting the big toe. Possible triggers include previous trauma and chronic irritation or infection. We describe two atypical cases of SE in two young women presenting with pyogenic granuloma-like lesions clinically.

A qualitative study of seven simulation models for tendon repairs.

Seven models for tendon repair simulation (urinary catheter, liquorice, fishing lure, dental rolls, drinking straw, silicone sealant and the authors' modification of silicone sealant with Micropore™ tape) were assessed for their performance in a number of domains. The silicone sealant and surgical tape model scored highest overall and for each individual domain. This was significantly higher than all other models with the exception of the silicone sealant alone.

Occupational Localized Cutaneous Argyria With Pseudo-Ochronosis in a Jeweler.

A case of localized argyria in a 36-year-old female jeweler is described who presented with 2 discrete and asymptomatic bluish-black pigmented macules on the pulp of her left middle finger. A skin biopsy from both lesions demonstrated deposition of brown/black pigmented granules along the basement membrane zone of eccrine glands, blood vessels, nerves, and the dermo-epidermal junction fully in keeping with silver deposition. In addition, there was yellow-brown deposition seen within the interstitial dermis mimicking an early form of ochronosis, so called "pseudo-ochronosis.

A rare case of a digital papillary carcinoma of the hand with secondary conservative management.

A digital papillary carcinoma (DPC) is a cancer of the sweat glands which develops on the digits of the hands and feet. With an incidence of 0.08 per 1 000 000 people/year, it is often initially misdiagnosed as a simple ganglion although it has a significant risk of metastasis.

Lipomatous tumours of the hand and wrist A series of 25 cases and review of the literature.

Unlabelled: consequently reports in the international literature are mainly of individual cases and small series.

Material Of Study: This is a retrospective review of a series of 25 patients with lipomatous tumours of the hand and wrist treated between 2001 and 2009. All patients underwent clinical and radiological assessment and a marginal excisional biopsy.

Current management of Jersey finger in rugby players: case series and literature review.

We discuss a combination of established and modern techniques in the investigation and management of traumatic flexor digitorum profundus rupture ('Rugger Jersey Finger') in seven cases (male rugby players ranging from 15 to 30 years of age; mean = 26). We discuss the use of X-ray and ultrasound investigation followed by various surgical repairs including intraosseous sutures, suture anchors, tendon lengthening and "pull-through suture over button" repairs. Functional outcome at outpatient follow-up is discussed in each case.

Ultrasound-guided percutaneous release of the annular pulley in trigger digit.

The purpose of this study was to describe and evaluate a new technique for ultrasound-guided percutaneous release of the annular pulley in trigger digit using a modified hypodermic needle. A total of 35 ultrasound-guided percutaneous releases were performed on 25 patients diagnosed and referred by hand surgeons in our institution over 16 months from October 2006. Inclusion criteria were as follows: adulthood, triggering present for at least 4 months, failure to respond to conservative management or steroid injections, no previous history of pulley release in the affected digit.

The "transverse intraosseous loop technique" (TILT) to re-insert flexor tendons in zone 1.

Flexor tendon divisions in Zone 1 need to be re-inserted to the distal phalanx. This paper describes the Transverse Intraosseous Loop Technique (TILT) of re-inserting the profundus tendon to the distal phalanx in which an internally placed suture is looped through the bone and tendon interface. It provides a strong repair, which permits the desired tensioning and can be performed in children.

Atraumatic hand infection in an infant.

We report a rare case of atraumatic infection of the extensor tendon sheaths. Acute medical staff should be aware of the insidious nature of presentation of this condition, as early aggressive treatment is required to prevent tendon rupture. In this instance, an excellent functional outcome was achieved by surgical drainage and early tendon reconstruction.

Replantation of total degloving of the hand: case report.

This article reports a patient who had a total degloving of the hand, caused by a roller injury, up to the distal forearm level. The authors replanted the degloved skin using arteriovenous anastomosis of the radial artery at the wrist to the cephalic vein in the degloved skin in an end-to-side manner. To enhance the survival of the replanted skin, it was deepithelialized and buried in an abdominal pocket created specifically for this purpose.

Craniofacial abnormalities induced by retinoic acid: a preliminary histological and scanning electron microscopic (SEM) study.

Exogenous retinoic acid has been found to be teratogenic in animals and man. Craniofacial defects induced by retinoic acid have stimulated considerable research interest. The present report deals with scanning electron microscopical observations of the craniofacial region concurrent with histological examination of craniofacial dysmorphism induced in rat embryos following maternal treatment treated with varying dosages of all-trans-retinoic acid (tretinoin).

All trans retinoic acid interfering with palatal development. Scanning electron microscopical and light microscopical observations on embryonic rat palate.

Diverse studies on retinoic acid teratogenesis, during the recent years, indicate that the drug's analogues target on diverse cell population during differentiation in mammals. During an extended teratological protocol concerning retinoic acid influence in diverse embryonic tissue differentiation in experimental animals we studied all-trans-retinoic acid's influence on palatal development in the white rat embryo. For this purpose, six groups of white rat embryos were studied: Group 1 was treated with 100 mg/kilogram of body weight (k.
