The treatment of early cutaneous capillary haemangiomata (strawberry naevi) with the tunable dye laser.

We have treated 39 early cutaneous capillary haemangiomata, in 24 infants, with the tunable dye laser at a wavelength of 585 nm (SPTL 1b, Candela Corporation, Wayland, MA, USA). The average age at first treatment was 13 weeks. The first signs of involution were seen at 19 weeks of age. Complete resolution of the lesions was seen in 61. 5% of haemangiomata at an average age of 39 weeks. Two haemangiomata did not respond to laser treatment and were treated successfully with intralesional steroid injection. There were no complications of laser treatment. The natural history of the treated haemangiomata was significantly shorter than historical evidence suggests for untreated lesions. Haemangiomata may be treated safely and effectively with the tunable dye laser in the early weeks of life leading to accelerated involution and resolution.

Treatment of traumatic tattoos with the Nd YAG laser: a series of nine cases.

Inadequate primary skin cleansing for dirt-ingrained skin abrasions can result in disfiguring traumatic tattoos. We present nine cases of traumatic tattoos treated with the Nd YAG laser. In six cases the pigmentation was completely cleared and in three cases minimal pigmentation remained. The Nd YAG laser offers effective late treatment of traumatic tattoos with many advantages over conventional destructive treatment modalities. The best treatment is still immediate debridement and cleaning.

Fingertip reconstruction with a dorsal island homodigital flap.

A distal dorsal island homodigital flap has been used for reconstruction of fingertips in nine patients who sustained traumatic amputations either obliquely or transversely through the middle of the distal phalanx. Seven of the nine patients attended for follow-up. All the flaps survived with the exception of a small area of partial necrosis in one patient. Fingertip reconstruction with this flap is a one-stage procedure, safe, easy to perform and provides durable tissue support for the nail to regrow undeformed.

Three wall orbital decompression for Graves' ophthalmopathy via a coronal approach.

Ten patients with dysthyroid eye disease who underwent a three wall orbital decompression procedure performed via a coronal approach were reviewed. The indications, results, complications and surgical techniques involved in this surgery are discussed. We believe that this approach offers a number of advantages over other techniques and has a role in the management of carefully selected patients with dysthyroid eye disease who have severe unilateral or bilateral proptosis, with or without dysthyroid optic neuropathy.

Immediate exposed skin grafting in children's burns.

The technique of immediate exposed skin grafting following early tangential excision of burns in children overcomes the difficulties of applying dressings with the attendant risk of graft loss from shearing forces. We report on 36 patients treated by this method. Wound healing was achieved in all patients without the need for further surgery.

The stretched scar: the benefit of prolonged dermal support.

A study of skin suture following elliptical excision of tattoos from the upper limb shows that when the dermis is supported by a subcuticular non-absorbable suture for 6 months there is (a) a highly significant and numerically considerable (37.5%) reduction of scar stretching over that following conventional interrupted skin suture and (b) a significant reduction of scar width (15.7%) when compared with the same material used as a subcuticular suture for 3 weeks. Subcuticular polyglycolic acid achieved no reduction in scar width at one year when compared with conventional interrupted sutures.

Blindness following cosmetic blepharoplasty--a review.

A case of unilateral blindness following cosmetic blepharoplasty is reported. A review of some 60 previously recorded cases is made with a more detailed analysis of 22 cases. An attempt has been made to highlight the opinions on causes and treatment held in common by those authors who have previously reported and discussed their cases. A degree of retrobulbar haemorrhage was a feature common to most cases and the final event leading to permanent visual impairment was usually ischaemia of retinal or optic nerve tissue. The relationship between these findings remains uncertain although intra-orbital compression was thought to be a frequent common pathway. Recommendations to reduce the chance of this rare but serious complication are made. The importance of simple pre-operative eye records and the early involvement of an ophthalmic surgeon when retrobulbar haemorrhage arises are stressed.

Tumour spread in a delto-pectoral pedicle flap used in reconstruction of the lower jaw: case report.

A number of well-established pedicled flaps, including for example the delto-pectoral and pectoralis major flaps, are used in reconstructive work following excision of head and neck tumours. The most commonly encountered tumours of the head and neck spread predominantly via the lymphatic system and during the time between the insetting of a flap and the division of its pedicle some micro-lymphatic continuity of flow must develop from the site of insertion down the flap to its pedicle. This may form a route for spread of tumour when the primary lesion has been inadequately excised. A case report is presented.

The degloved hand: immediate complete restoration of skin cover with a contralateral forearm free flap.

This paper describes a method of repair of a serious injury with major skin loss on both the volar and dorsal aspects of the hand and wrist using a free "forearm flap" from the opposite limb. The technique is a one-stage procedure, provides a completely variable amount of skin, the freedom to elevate the repaired hand and the opportunity to revascularise the most distal structures using the vessels incorporated in the flap.

Euglycemic control of gestational diabetes mellitus by specific dietary manipulation: a case study presentation.

Gestational diabetes is the most common complication of pregnancy. If maternal hyperglycemia is not well controlled, excess glucose is transmitted to the fetus, which can lead to fetal macrosomia and maternal and fetal complications. Dietary treatment for gestational diabetes varies among practitioners. A case review is presented of a 32-year-old white woman with gestational diabetes whose condition was complicated by her blood glucose intolerance to lactose in milk. By following a carefully monitored regimen using specific dietary manipulation to maintain normoglycemia, the woman was able to deliver a normal, healthy baby by spontaneous vaginal delivery.
