Guidelines for the excision of cutaneous squamous cell cancers in the United Kingdom: the best cut is the deepest.

Surgical excision remains the gold standard for the management of cutaneous squamous cell cancers (SCC) and national guidelines for operative radial margins predict 95% oncological clearance with a margin of 4 mm for low-risk and 6 mm for high-risk tumours. We retrospectively analysed all cutaneous SCC excisions performed across 4 regional Plastic surgical units in England over a consecutive 24-month period and collected data on tumour characteristics, operative and histological margins and completeness of excision. We identified 633 eligible SCC excisions of which 265 (42%) were over 2 cm in diameter with 37 recurrent tumours (5.8%). The mean radial operative margin was 6.5 mm across all tumours and 8.4 mm for tumours greater than 2 cm. The mean histological tumour diameter was 21 mm. The overall incomplete excision rate was 7.6% (7.9% for tumours >2 cm). Ninety-four percent (45/48) of incomplete excisions involved the deep margin and only 3 out of 633 excisions (0.47%) were incomplete at a radial margin only. No differences were observed in tumour size or excision margin between incompletely and completely excised tumours. Incomplete excisions were most common on the ear, nose and cheek. In summary our analysis demonstrates that despite adherence to recommended surgical margins for cutaneous SCCs the incomplete excision rate remains higher than expected. We believe that this is because most incomplete excisions are incomplete at the deep margin and question the utility of performing increasingly wide excisions, and, the generalisability of the evidence upon which recommendations for radial margins are based.

A comparison of serial halving and the rule of nines as a pre-hospital assessment tool in burns.

Following endorsement of serial halving by the Faculty of Pre-Hospital Care of the Royal College of Surgeons of Edinburgh this study aimed to determine whether the technique was comparable to the rule of nines in making initial assessments of body surface area burned. Ten 'casualties' were made up to represent burn victims (range 6-61%). An external panel of six consultants and one specialist registrar in plastic surgery were invited to assess the simulated casualties. They gave individual and a consensus estimate of the burned areas. One hundred and twenty-five members of local emergency services and military paramedical staff were given a brief video and slide presentation describing either the rule of nines or serial halving method of burn area assessment. These techniques were then used to assess the 10 simulated casualties, giving 1250 estimates of burn surface area. The understanding of both techniques appeared adequate in both test groups. Estimates from serial halving and rule of nines groups differed from the assessments of the external panel. No statistical difference was demonstrated between serial halving and the rule of nines as an initial assessment tool when determining disposal. Serial halving has an inherent weakness when assessing certain sizes of burn. The rule of nines requires that the assessor knows and understands the proportionate areas of the body. The mathematics of percentages and fractions appeared to confuse some assessors.

Initial plastic surgery experience with the first telemedicine links for the British Forces.

In January 1998, the first telemedicine link for the British Defence Medical Services was established between the British military hospital in Sipovo, Bosnia and the Royal Hospital Haslar, the main triservice hospital in the UK. Further links were established later in the year. These simple links use a high-resolution digital camera, the Olympus C1400L and the C1400XL, to capture still images. These are then transmitted without loss of definition as electronic mail attachments to obtain specialist opinions in plastic surgery as well as in radiology, dermatology, orthopaedics, urology, ophthalmology, general medicine, maxillofacial surgery and pathology. Its use is illustrated by representative case reports from the first 11 referrals from Sipovo and elsewhere to the Plastic Surgery Department at Haslar. This system is suitable for use within both a military and a civilian context, anywhere in the world. It can readily be adapted for use by general practitioners and hospital doctors to facilitate referrals to plastic surgery departments.

What do plastic surgeons do?

The image of plastic surgery as portrayed by the media is of concern to all plastic surgeons. In order to assess knowledge about the specialty, a questionnaire was devised and given to five groups of participants: general practitioners, medical students, nurses, plastic surgical out-patient attendees, and the general public. The results revealed that general practitioners, nurses and medical students in the Cambridge area are, on the whole, knowledgeable about the role of plastic surgery. However, the general public are not so well educated and 23.7% of them could not think of five conditions treated by plastic surgeons, and felt that burns and cosmetic problems were the commonest conditions dealt with. Improved liaison with general practitioners, other specialties and more teaching of undergraduates, coupled with more effective promotion of the skills on offer might permit better use to be made of the specialty.

Hereditary multiple glomangiomas.

Hereditary multiple glomangiomas are an interesting rare problem which can either present as multiple painful cutaneous lesions or, rarely, a cosmetic challenge due to site, size or number of lesions. It may also pose a diagnostic dilemma, which can only be settled by biopsy. Malignant change in glomangioma is extremely rare and only a few cases are well documented in literature. A case report of this condition, along with extensive review of the literature, is presented. The prognosis of various forms of glomangiomas and efficacy of diagnostic and therapeutic tools is discussed.

Munchausen's syndrome--masquerading as necrotizing fasciitis.

We would like to present a novel form of Munchausen's syndrome which presented us with a difficult problem in the midst of the recent media hysteria regarding flesh eating bacteria. This condition, first described by Richard Asher in 1951, is often very difficult to diagnose and it is not, therefore, surprising that the victims have been through several episodes of treatment before the suspicions of staff are raised. It owes its name to a fictitious character, Baron Karl Friedrich Hieronymus Freihess von Munchausen, who recounted extraordinary and wildly exaggerated exploits of adventure and daring, not unlike patients who present with this condition. Our enquiries revealed that the laid down procedure when faced with a patient with this condition is that the regional medical officer (RMO) should be contacted. It is then his responsibility to contact other RMOs, who in turn pass the information on to accident and emergency consultants in their area.

A flap for segmental loss of a digital nerve. The Venkataswami flap revisited.

The use of a V-Y advancement flap for reconstruction of a volar/lateral soft tissue defect in a digit involving segmental loss of the neurovascular bundle of up to 10 mm at middle phalangeal level is described. This flap allows immediate reconstruction with primary repair of the nerve and gives good functional results. Two cases are presented.

The goalkeeper's fear of the nets.

The soccer goalkeeper is particularly prone to injuries of the hands. We report three cases in which soccer goal-posts were the cause of a hitherto unrecorded type of accident, which resulted in severe ring avulsion injuries requiring surgical amputation or replantation. In each case the injury occurred when a ring worn by the goalkeeper caught on one of the hooks by which the netting is attached to the goal-posts. Proposals made for the prevention of such injuries include increased awareness through education, discouragement of the wearing of rings during sporting activities and the redesign of the attachment systems of goal nets.

Burn injuries in boating accidents.

We report a series of burn injuries sustained on boats and admitted to Stoke Mandeville Hospital over a 4-year period. Nine patients are presented, aged between 27 and 65 years. Total body surface area burned ranged from 1.5 to 83 per cent. The causes of the injuries, and the factors leading to the accidents which caused them, are discussed. Interviews with a number of private boat owners and hirers revealed an inadequate level of fire and safety precautions taken. There is at present no legal requirement for private boats to carry five fighting equipment. We believe there is a need for definition of the minimum legal level of such equipment to be carried on board. Increased awareness of correct fuel storage and handling requirements is felt to be important, especially with the increasing popularity of boating as a leisure and sporting activity.

First dorsal metacarpal artery flap cover for extensive pulp defects in the normal length thumb.

Use of the first dorsal metacarpal artery flap to cover extensive pulp defects in the normal length thumb in five patients is described. The advantages of the procedure include provision of sensate cover of exposed distal phalanx to the tip of the thumb with minimal donor site morbidity. Its use, particularly in the older patient, with immediate postoperative mobilisation and the avoidance of nerve repair or more complicated microsurgical procedures, is discussed.

Burns following cigarette lighter fluid abuse.

Seven patients with burns associated with butane cigarette lighter fluid abuse, in a group setting within an enclosed space, are presented. In all patients there was a reluctance to admit that butane vapour was in use as an intoxicant immediately prior to the injury. It is obvious from the circumstances of these injuries that the hazardous nature of cigarette lighter fluid is not fully appreciated. Since the resultant injuries are usually minor (all patients recovered spontaneously with conservative management, the hospital stay averaging 2 days), it is probable that many more occur, but do not present to accident departments as the victims are wary of repercussions should they admit to intoxicant vapour abuse. In view of the medical sequelae that can follow butane inhalation, burns unit staff should be aware of the problems, their recognition and treatment.
