Flame burn admissions and fire fatalities in Scotland with particular reference to the Strathclyde (Glasgow) region, and their prevention.

Scotland has the highest rate of fire fatalities in the UK. Nearly 50% of the population and fire deaths in Scotland are in the Strathclyde region. The data from the burns unit at Glasgow Royal Infirmary were studied to find the number of admissions due to flame burns and see how it compared with the fire deaths. During 1981-1993, amongst 2771 admissions to the burns unit, 1181 (43%) were due to flame burns and out of these flame burn victims, 69% were adults, 16% elderly and 15% children. The distribution of cases according to the total body surface area (TBSA) involvement was 866 (73%) with 1-15%, 165 (14%) with 16-30%, and 150 (13%) with > or =31% TBSA burns. The annual number of flame burn admissions declined during 1981-1993. In the Glasgow region 50% of the domestic fires leading to non-fatal burns or to death were started by misuse of smoking materials. Chip pan fires were responsible for 8% of admissions to the burns unit. The annual number of fire fatalities when reviewed for a longer period 1973-1995 also showed a decreasing trend. Further educational and legislative measures to prevent flame burns are discussed.

Radial tunnel syndrome: diagnosis and management.

This study presents a review of 26 cases of radial tunnel syndrome in 25 patients seen in a single hand consultant's practice over a period of 2.5 years. The protocol for diagnosis was the reproduction of patient's symptoms on pressure over a palpable tender spot along the course of the radial tunnel, painful resisted supination or resisted middle finger extension, all of which were abolished on infiltration of the tender area with a local anaesthetic solution. The presence of at least two out of three objective signs was necessary for the diagnosis. Initially all cases were treated conservatively, by steroid injection in 25 and physiotherapy in one, with long-term relief of pain in 16. Nine failures were treated surgically, with complete relief of pain in seven. Radial tunnel syndrome should be considered in the differential diagnosis of pain around the hand and or elbow.

Transthecal digital nerve block. An anatomical appraisal.

Injection studies using methylene blue and latex were used in 60 digits from 40 cadavers to study how anaesthetic fluid injected into the flexor tendon sheath might spread around the proximal part of the finger. The injected solution escaped from the flexor tendon sheath around the vincular vessels which are present near the base and head of the proximal phalanx. Outside the digital canal, the dye flowed smoothly through the perivascular loose areolar tissue and spread alongside the main digital vessels and nerves and their palmar and dorsal branches.

Silicone gel-filled breast implants and connective tissue diseases.

Recent worldwide press and media speculation that silicone implants may be linked to an increased incidence of breast cancer, other cancers, and connective tissue diseases-particularly systemic sclerosis-is a current cause for concern to the medical profession and public alike. We conducted a cross-sectional study of the prevalence of connective tissue diseases, as well as signs and symptoms associated with these conditions, in women who had received a silicone gel-filled breast implant for either breast augmentation or breast reconstruction following mastectomy for breast cancer compared with women without implants in South East Scotland. We compared 317 patients who had had a silicone gel-filled breast implant inserted with matched controls. We found no increased incidence of antinuclear antibodies or rheumatoid factor in the study groups. We detected one case of rheumatoid arthritis in the reconstruction group and one in matched controls, but no cases of any other connective tissue disease. No cases were found among the augmentation patients or their controls. No differences were found in symptoms or physical signs of connective tissue diseases between the study patients and their controls. This study has failed to find any case for a link between silicone gel-filled breast implants and connective tissue diseases.

Nerve supply of the breast with special reference to the nipple and areola: Sir Astley Cooper revisited.

Cooper in 1840 described mammary branches from the 2nd-6th intercostal nerves, and noticed that the nipple was supplied by branches which lay close to the surface of the gland. Eckhard (1850) divided the mammary branches into superficial branches to the skin and nipple, and deep branches to the glandular tissue and nipple, but many later authors ignored those findings. After the second World War, cosmetic surgery of the breast made further research critical, as surgeons strove to design operations which would retain its shape and preserve postoperative sensation. Craig and Sykes (1970) described mainly anterior branches from the 3rd, 4th and 5th intercostal nerves passing through the glandular tissue of the breast and along the line of the ducts to the nipple, while Farina et al. (1980) concluded that the nipple was supplied solely by superficial lateral branches of the 4th nerve. Using improvements in dissecting technique learned from microsurgery, Sarhadi et al. (1996) found that the nipple was innervated by the lateral cutaneous branch of the 4th intercostal nerve, by two branches, one passing superficial to the gland, and the other through the retromammary space, and by variable lateral and medial additional branches from the 2nd-5th nerves. These branches came to lie superficially and formed a subdermal plexus under the areola. This account is uncannily close to Cooper's original description; it is a reassuring, if sobering, conclusion that his early account remains one of the most reliable.

An anatomical study of the nerve supply of the breast, including the nipple and areola.

There are widely differing accounts in the literature of the origin, course, and distribution of the nerves to the breast and especially to the nipple and areola. This, together with our own findings at operation, led us to investigate whether the accounts are inaccurate or the nerve supply is very variable or both. 15 breast specimens from dissecting room cadavers, 12 female and 3 male, were dissected to study the nerve supply of the breast in detail. In the female, the breast received its innervation from the lateral and anterior cutaneous branches of the second to the sixth intercostal nerves and from the supraclavicular nerves. On the lateral side in the 12 females, branches from the third (9/12), fourth (12/12) and fifth (4/12), and on the medial side branches from the second (3/12), the third (6/12), the fourth (4/12) and the fifth (2/12) intercostal nerves were traced to a plexus under the areola. Branches from the sixth intercostal nerve supplied the lower part of the breast but there was no direct branch to the nipple. The nerves to the nipple lay in the superficial fascia and passed through the subdermal tissue of the areola to form a plexus under it. The extent of the contribution by each nerve was variable, and it differed even on the left and right of the same cadaver. The nerve often described as passing through the inferolateral part of the breast to reach the nipple is a deep branch from the anterior division of the fourth lateral cutaneous nerve. This was present in 11/12 of the female breasts but it is not the only nerve to reach the plexus under the areola as sometimes claimed. The male breast had a similar nerve supply but the nerves were lying close together, whereas in a female breast they are spread out more widely.

Trends in burn admissions in Scotland during 1970-92.

This retrospective study involved analysis of the data of the inpatients discharged with a diagnosis of burns, from various hospitals in Scotland, during the period 1970-92. There were 51,350 such inpatients all over Scotland, with an average annual rate of 2233 cases. Overall burn incidence in actual numbers was 43.7 per cent in < 15 year olds, 41.2 per cent in 15-64 year olds and 15.1 per cent in > or = 65 year olds. Burn rates per 100,000 population were highest in < 15 year olds and lowest in 16-64 year olds. The pattern of burn admissions has changed. Since 1987 the highest numbers of burn inpatients were the 16-64 year olds, followed by children, then the elderly. There has been a gradual but sustained fall in burns admissions in all age categories. The downward trend was statistically significant (t = 8.48, 21 d.f., P < 0.001). Though the population of the elderly (> or = 65 year olds) increased by about 13 per cent, the burn admissions and all deaths due to burns did not reveal an upward trend. The population of the old (81+ year olds) increased by 60 per cent during the same period. The incidence of burns was above average when > 80 year olds were considered separately, approaching the levels found in children. However the rate and incidence of burns in the 65-80 year olds resembled that of the younger age group (16-64 year olds). The total number of deaths due to burns and/or smoke inhalation has declined in all age groups and the decline has been statistically significant (chi-squared = 19.62, 1 d.f., P < 0.001). Maximum number of deaths occurred in > or = 65 year olds (44 per cent), followed closely by 16-64 year olds (43.5 per cent), and 12.5 per cent of deaths in adolescents and children. The decline was due to improved management of burns and a decrease in the number of patients having large body surface area burns.

Burns in the elderly in the south east of Scotland: review of 176 patients treated in the Bangour Burns Unit (1982-91) and burn inpatients in the region (1975-91).

One hundred and seventy-six patients aged 65 years and above, treated in Bangour Burns Unit during a 10-year period between 1982 and 1991 were studied in detail. Annual number of burn cases treated as inpatients in the South East of Scotland, within or outwith the Bangour burns unit, and all deaths due to burns, during the period from 1975 to 1991, among the estimated population were analysed to assess the trend in incidence and rates of burns in elderly persons in the community.

Declining incidence of paediatric burns in Scotland: a review of 1114 children with burns treated as inpatients and outpatients in a regional centre.

This retrospective study of paediatric burns in the Lothian region involved a review of 1114 case notes of children up to the age of 12 years, treated for burns as inpatients and outpatients, during a 3-year period between 1988 and 1990. There were more boys than girls and 79 per cent were below 5 years of age. 71.5 per cent were treated as outpatients only, whereas 28.5 per cent were admitted. The Lothian region had the highest incidence of burns of children in Scotland. There has been a statistically significant downward linear trend in burn rates and admissions in Scotland during the 20 years but in this hospital burns admissions have significantly diminished only since 1987. The number of flame burns has declined and a high proportion of the victims were scalded. Efforts need to be made to reduce the large number of scalds by educational and legislative measures.

Experience with the adipofascial turn-over flap.

Use of the adipofascial turn-over flap has been extended to cover such complex wounds of the extremities as defects over exposed joints and fracture sites. Experience with 10 consecutive cases and long-term follow-up confirmed that this flap is easy to plan and quick to raise, with minimum donor site morbidity and high success rate.
