Somato-somatic theory of referred pain elucidates observations of referred sensations during micropigmentation of nipple-areolar complex in a cohort study on patients undergoing pedicled latissimus dorsi flap breast reconstruction.

AIM: Micropigmentation of the nipple-areolar complex is the final aesthetic step in autologous breast reconstruction. The mechanism of referred pain observed in patients during micropigmentation after a non-neurotonized pedicled latissimus dorsi flap breast reconstruction is poorly understood. METHODS: Patients undergoing micropigmentation for nipple-areolar restoration at our breast unit were included in this study. Baseline sensitivity of both breasts was recorded using a questionnaire and non-invasive Semmes-Weinstein monofilament testing. Patients experiencing local and regional referred symptoms, while undergoing micropigmentation, were identified and their clinical data were collected and analysed. Three months postoperatively, the patients completed a questionnaire pertaining to their satisfaction and future analgesic preference. RESULTS: Thirty (17.8%) patients experienced referred sensations during micropigmentation. Their symptoms ranged from "ache" (6.7%), "discomfort" (13.3%) to "deep pain" (13.3%) and were either local and/or referred to ipsilateral axilla, upper limb and back. The majority were pleased with postoperative outcomes [shape (30, 100%), size (28, 93.3%), colour match (22, 73.3%)] and a small number were not satisfied with the shape (2, 6.7%,) position (1, 3.3%) and appearance of the tattoo (1, 3.3%). CONCLUSION: Micropigmentation is a safe procedure with good patient satisfaction and low rates of complications; however, patients may experience significant local or referred symptoms. This observation can be explained by the proposed "somato-somatic" theory of referred pain and ascertains the need for use of oral and/or local anaesthetic as well as improved counselling in these patients.

A case series of skin necrosis following use of non invasive ventilation pressure masks.

Two cases of nasal skin necrosis secondary to pressure from the use of continuous positive airway pressure (CPAP) face masks are presented. Both developed skin necrosis as a result of wearing these masks over the nasal bridge. These cases highlight the need for clinical vigilance in application of CPAP masks, the need for monitoring the skin of the nose during CPAP use and the possible need for modifications in design to help prevent this serious complication.

Rhinectomy for the management of nasal malignancies.

BACKGROUND: Tumours of nasal skin or mucosa are common, and can usually be treated with limited surgical excision or radiotherapy. This paper highlights a subset of high risk tumours which require rhinectomy for complete oncological clearance. METHOD: Retrospective case note review of 14 patients undergoing rhinectomy for nasal tumours. Clinical and histological findings, treatment and outcome are reviewed and discussed. RESULTS: Forty-three per cent of patients had recurrent disease and underwent rhinectomy as a salvage procedure following previous surgery or radiotherapy. Most tumours (79 per cent) were basal cell carcinoma or squamous cell carcinoma. After a mean follow up of 30.1 months (range, zero to 96 months), seven patients (50 per cent) were alive and disease-free. Reconstruction was most commonly with a prosthesis. CONCLUSION: Rhinectomy is an oncologically sound procedure for the management of high risk nasal malignancies. Prosthetic rehabilitation can be an excellent alternative to surgery, particularly in those patients unsuitable for major reconstruction.

A review of diagnostic imaging in melanoma.

The incidence of melanoma continues to rise, and is responsible for 50% of deaths related to skin cancer. Imaging plays a vital role in the diagnosis, assessment, treatment and follow-up of patients. Costs have risen dramatically over the last few years, largely due to increased use of newer technologies. This article examines the evidence for the use of radiological imaging in melanoma, in particular, ultrasound, computerised tomography (CT), magnetic resonance imaging (MRI), sentinel lymph node biopsy (SLNB), positron emission tomography (PET) and combined CT/PET. Recommendations are made on the basis of comparison of costs of imaging methods.

Is crow's feet sign a reliable indicator of corneal injury in facial burns?

Facial burns occur commonly, although they rarely result in serious ophthalmological injuries. Despite this, failure to identify and manage minor eye injuries can have serious consequences. When the blink reflex is forcibly suppressed, the cornea is left exposed, resulting in serious injury. One indicator of possible corneal injury is the absence of 'Crow's feet sign'. Crow's feet sign describes the sparing of the skin creases or crow's feet around the eye with forced eyelid closure. The implication is that the patient was conscious at the time of injury and therefore able to protect the eye from ocular injury. We present a consecutive series of 145 people with facial burns attending the burns unit at Selly Oak Hospital, Birmingham over a 2-year period. Demographics, cause, presence of inhalational injury and outcome were examined for all patients. Eleven patients were diagnosed with ocular injury, and none of these patients had crow's feet sign. To date, we have found 100% correlation between the presence of crow's feet sign and the absence of ocular injury. We would recommend that clinicians are alert to the absence of this sign as a marker of possible eye injury.

Merkel cell carcinoma: a report of 34 cases and literature review.

BACKGROUND: Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer, with unclear histogenesis. To date there is no consensus on the optimal treatment of this neoplasm, with controversy surrounding the use of radiotherapy and chemotherapy. There are also limited data on biological behaviour and prognosis, with reported survival ranging from 31% at three years to 74% at five years. METHOD: The medical records of 34 patients with a diagnosis of primary MCC, treated at two NHS trusts in Birmingham and Coventry, were reviewed. An extensive review of the English literature was also performed. RESULTS: MCC occurred predominantly in Caucasians (97%) with a mean age of 75 years. Identified risk factors were a previous history of SCC (37%), BCC (18%) and AK (20%). Ten percent of patients showed evidence of immunocompromise. Most tumours were located on the extremity, where they reached a mean size of 2.1cm. Fifty percent had regional metastasis during the course of their disease. A sub group analysis of the excision margins showed that a 2-cm excision margin, extending to the deep fascia, resulted in a 50% incomplete excision rate and a 33% local recurrence rate. In contrast a 3-cm margin including deep fascia resulted in no incomplete excisions and a 10.5% local recurrence rate Prognosis was poor with a 40% 3-year survival. Combining the data from two trusts has produced a relatively large series and highlighted differences in patient characteristics and management between the units. We advocate a 3-cm excision margin, including fascia wherever possible, combined with post-operative radiotherapy to offer the best chance of local control. Survival is fairly dismal and in keeping with the aggressive nature of this tumour. The respective roles of radiotherapy and chemotherapy remain controversial.

Infected palmar pits: a rare presentation of Gorlin's syndrome.

This paper presents a rare hand presentation of Gorlin's Syndrome, also known as Naevoid Basal Cell Carcinoma Syndrome, which has not been reported previously. This condition is an autosomal dominant, multisystem condition whose diagnosis is important to ensure further surveillance and treatment of features of the condition not routinely dealt with by hand surgeons. However, hand surgeons should be aware of this condition and those parts of the syndrome which may present to them.

The management of hand injuries caused by sea urchin spines.

Injuries to the hand by sea urchin spines are not commonly seen in the United Kingdom. There are many varieties of sea urchins (Echinoidea) throughout the world. They have a spherical calcium carbonate exoskeleton covered with spines. Certain varieties may be venomous, in particular the flower urchin (Toxopneustes pileolus) found in the Indo-Pacific oceans. Injury may also be caused by the urchin spines or pedicellaria (delicate seizing organs equipped with jaws). A small number of hand injuries associated with sea urchin spines have been reported in the literature.

Views of UK melanoma patients on routine follow-up care.

Although the need for melanoma follow-up is universally accepted, there is still much debate on the duration and frequency of appointments. The UK guidelines were revised in June 2002 to streamline melanoma follow-up. Following the change in protocol, some of our patients expressed concern at the shorter duration of follow-up. We therefore polled all our active melanoma patients to obtain their views on the outpatient clinics. In particular we asked whether they would be happy to have routine follow-up in a primary care setting. In conjunction with the department of psychology, a short questionnaire was devised assessing patient satisfaction and concerns about follow-up. This was sent to all active melanoma patients in our trust. Out of 304 eligible patients currently attending outpatients, 231 (76%) completed replies were received. Ninety-eight percent of respondents found the clinics to be useful. Twenty two and a half percent felt it was difficult to attend the clinic and this was mainly due to logistical problems, i.e. hospital car parking. The majority were reassured by the clinic visits and felt it was a chance to ask questions and check for new disease. Of the 12% of respondents who had a recurrence, 52% indicated that they had detected it themselves. Sixty percent of patients would be happy to consider routine follow-up with their GP, provided they were suitably experienced and trained. A survey of 50 local GP's found that 70% would be unhappy to monitor their patients. Patients want and benefit from follow-up. However, they are an increasing burden on outpatient clinics, given the increasing incidence of melanoma. GP follow-up may be appropriate for a small subgroup of patients. This combined with shared care and practice based clinical nurse specialists may be the way forward in melanoma follow-up.

Axillary metastases from recurrent oral carcinoma.

The rationale for surgical treatment of head and neck cancer is based on a predictable pattern of metastasis. There is aberrant or unpredictable spread rarely and typically only in recurrent disease. There are few published reports to our knowledge of axillary metastases from squamous cell cancer (SCC) of the head and neck. We present a patient who developed axillary node disease on the other side after recurrence of a squamous cell carcinoma of the floor of the mouth. She died 11 months after excision of the recurrence.

Psychosocial benefits of sentinel lymph node biopsy in the management of cutaneous malignant melanoma.

Lymphoscintigraphy combined with sentinel lymph node biopsy has become a powerful and sensitive tool in establishing nodal spread in cutaneous melanoma, as well as in breast and other cancers. Although the technique is reliable and validated, there is, as yet, no proven clinical benefit. A suggested benefit of sentinel lymph node biopsy is that a negative biopsy may decrease the psychological morbidity associated with malignancy by reassuring the patient that he or she has localised disease. We studied a group of patients with cutaneous melanoma who underwent sentinel lymph node biopsy, and found that although they did gain some psychosocial benefit from the procedure, this was short term and they were still significantly concerned about their disease status.

Cutaneous leishmaniasis.

The incidence of leishmaniasis is increasing globally due to population and environmental changes. Ease of worldwide travel and immigrant populations means that the UK surgeon is more likely to encounter cutaneous lesions. Two cases are presented and treatment options discussed.

A custom-made thermoplastic boot splint for the treatment of burns contractures of the feet in children.

Scald injuries to the feet are relatively common in young children. In a minority of cases, contracture formation can lead to permanent disability. We present a new technique, which provides a simple yet functional form of splintage in the treatment of the contractures.
