Patients with acute skin loss: are they best managed on a burns unit?

Patients who are critically ill and have large areas of skin loss or breakdown present a difficult management problem. They require the combination of intensive therapy facilities to support failing organs and specialized skin care, sometimes including extensive debridement and reconstruction. The expertise required for both aspects of treatment are found uniquely on a burns unit. We present five patients with large areas of cutaneous loss or damage secondary to a variety of non-burn aetiologies who were managed on a burns unit. We suggest that a burns unit may be the most appropriate place for such patients to be treated during both the acute phase of their illness and the later stages of surgical reconstruction and physical rehabilitation.

Aberrant sentinel nodes in malignant melanoma.

The option of sentinel lymph node biopsy for patients with a cutaneous malignant melanoma has allowed an alternative to the traditional approaches to lymph node basin surgery. Lymphatic mapping usually identifies the sentinel node(s) in a recognised lymphatic basin, however aberrant nodes may occasionally be identified outside these areas. The notes of 100 consecutive patients with a localised cutaneous malignant melanoma, who had a sentinel lymph node biopsy in our unit, were reviewed. Lymphatic mapping identified three patients with aberrant sentinel lymph nodes. Failure to remove an aberrant sentinel lymph node harbouring metastatic melanoma may reduce significantly the chance of control or cure of the disease. In order to reduce this risk we advocate lymphatic mapping prior to surgical management of the draining lymph nodes of a cutaneous malignant melanoma.

Nontraumatic atlanto-occipital and atlantoaxial rotatory subluxation: case report.

OBJECTIVE AND IMPORTANCE: Concomitant atlantoaxial and atlanto-occipital subluxation resulting from any cause is extremely rare. We have found only five previously reported cases and describe another, suggesting a treatment plan. CLINICAL PRESENTATION: A 13-year-old female patient presented with a 3-month history of neck pain and decreased neck movements. All symptoms started after a localized neck infection had been treated successfully with antibiotics. There was no history of trauma. A diagnosis of postinfective atlanto-occipital and atlantoaxial rotatory subluxation was made based on a plain roentgenogram and was confirmed based on a computed tomographic scan. INTERVENTION: The atlantoaxial and atlanto-occipital subluxation was reduced during surgery. A posterior C1-C2 fixation was performed, and the atlanto-occipital joint was stabilized by means of a halo body jacket for 3 months. One year after removal of the jacket, all subluxation remained reduced and the patient retained significant neck movement. CONCLUSION: Disruption of the occipito-atlanto-axial complex can result from relatively minor head and neck infections and should be suspected in children with persisting neck pain and decreased neck movements. It may not be necessary to perform an occipitoaxial fusion to treat these patients, and a more limited fusion may be successful.

Glove usage and reporting of needlestick injuries by junior hospital medical staff.

The use of gloves when conducting invasive procedures and the reporting of needlestick injuries have been strongly encouraged. Despite this, neither practice appears to be universal. In order to determine the rates of glove usage and needlestick injury reporting, we conducted a survey of junior doctors in three hospitals in the UK. Of the 190 respondents, the majority rarely wore gloves for venesection, insertion of intravenous cannulas or arterial blood gas sampling. For more major procedures (insertion of central venous lines, insertion of thoracostomy tubes, suturing) gloves were invariably worn. Only 17.5% of needlestick injuries were reported. The rates of glove usage and needlestick injury reporting were lower than previous studies have demonstrated in North America. Surgeons suffered the most needlestick injuries and were the least likely to report them. The low reporting rate may have serious implications, particularly in view of the new Government guidelines on needlestick injuries which involve HIV-infected blood. By failing to use gloves and report needlestick injuries, junior doctors, in particular surgeons, are placing themselves and patients at increased risk of blood-borne transmissible diseases.

Distal amputations: impact of the introduction of femorocrural and femoropedal arterial bypass.

The aim of the study was to assess the impact of the introduction of femorodistal arterial bypass grafting on the patterns of lower limb amputation and reconstructive surgery, in particular the success rates of distal, conservative, amputations. Two 2-year cohorts of patients 7 years apart were analysed by a retrospective analysis of departmental audit and patient records. Significantly more patients undergoing distal amputation were considered to have reconstructible arterial disease in the later cohort. This was paralleled by an increase in the rate of suprapopliteal/popliteal and distal arterial bypass and a fall in below-knee amputation rate in this group of patients. The overall healing rate and rate of conversion of distal amputations were not adversely affected by the introduction of femorodistal bypass grafting, despite the fact that more distal amputees were non-diabetic in this second group. There was a high rate of success for distal amputations combined with femorodistal bypass, but the subgroup was too small for statistical analysis. We conclude that the use of distal amputation, with or without distal arterial bypass, offers a promising, although unproven, prospect for lower limb conservation even in non-diabetics.
