[Radiodermatitis in interventional radiology (hand dose measurement, screening and compensation)].

It is to be feared that the expansion of interventional radiology could lead to the reappearance of chronic radiodermatitis. Only a few studies mention the doses received by the hands, however these radiation doses are always high. Whereas clinical examinations lead to a belated diagnosis, capillary microscopy, a quick and non invasive test, enables to detect vascular injuries at the subclinical stage. Radiological protection is currently based on leaded gloves and on the reduction of exposure duration. Compensation for chronic radiodermatitis depends on the practitioner's status. In spite of a better evaluation of the overall irradiation, hand exposure remains a cause for concern. Capillary microscopy can provide appropriate medical surveillance.

[Collagen powder: hydrocolloidal dressings. Their effectiveness in radiodermatitis].

The authors analyze the effectiveness of a collagen cicatrizant powder for use in treating radiodermatitis compared with extra fine hydrocolloidal dressings by evaluating skin lesions according to the Radiation Therapy Oncology Group (RTOG) intensity scale. As the same time, the authors evaluate the patient's opinion regarding the treatment he/she receives. This study was carried out in the Valladolid University Clinical Hospital's Department of Radiotherapy. This study showed that the Catrix brand dressing is more effective than hydrocolloidal dressings as a treatment of lesions caused by radiodermatitis. Both the nursing personnel and patients involved in this study rated this Catrix product higher than those hydrocolloidal dressings products tested.

Chronic radiodermatitis following cardiac catheterization.

BACKGROUND: Fluoroscopy and cineradiography used during coronary angiography expose patients to some of the highest doses of ionizing radiation in diagnostic radiology. The possibility of radiation-induced damage has been discussed by several authors in the past. However, to the best of our knowledge, chronic radiation dermatitis caused by exposure to x-rays during cardiac catheterization has not been described. OBSERVATIONS: We describe 4 patients in whom chronic radiodermatitis developed following multiple cardiac catheterizations and coronary angioplasties. The cumulative radiation doses to which these patients were exposed were retrospectively calculated to be a mean of 24.6 Gy per patient, with a range of 11.4 to 34.9 Gy. CONCLUSIONS: Chronic radiodermatitis is a threat in patients undergoing multiple cardiac catheterizations and angioplasties. In susceptible patients, radiation doses as small as 11.4 Gy, which can sometimes be emitted during 1 or 2 procedures, are potentially harmful. Awareness and protective measures against this long-term side effect of cardiac catheterization should be encouraged.

Chronic radiodermatitis following repeated percutaneous transluminal coronary angioplasty.

We review three patients who developed chronic radiodermatitis subsequent to undergoing multiple percutaneous transluminal coronary angioplasties (PTCAs). All patients had had chronic ischaemic heart disease (IHD) and had undergone lengthy PTCA on several occasions. The skin eruption was characterized by an atrophic rectangular plaque on the left upper back, presenting as mottled hyper- and hypopigmentation with reticulate telangiectasia. Histologically, the eruption demonstrated epidermal atrophy, hyalinized and irregularly stained collagen, and telangiectasia of superficial vessels in the dermis. Although the risk of radiation injury in most patients undergoing cardiac catheterization is low, this danger should not be ignored. In particular, patients with long-standing IHD and numerous repeated catheterizations to only one or two occluded coronary arteries should be considered at high risk.

Long-term toxic effects of radiations: sarcomatoid carcinoma and multiple basal cell carcinoma of the limbs in chronic radiodermatitis.

A 73-year-old woman was referred to our attention for the presence of severe chronic lymphoedema and neoplastic lesions of the limbs. When she was 19 years old, the patient had undergone X-ray epilation of the limbs to remove unwanted body hair. The neoplastic lesions, observed 2 years before our observation, were excised, and histological examination revealed multiple basal cell carcinomas and a spindle squamous cell carcinoma on the left thigh. The case we observed offers some interesting points of consideration as it shows that in nonexposed areas cutaneous carcinomas can appear many years after irradiation and that the same treatment consequently requires careful follow-up for life. Another point of interest is the particular hystological aspect of neoplastic lesions in the site of radiodermatitis that requires in-depth immunohistochemical investigation for an exact diagnosis. Patients with previous treatment with ionizing radiation also in nonexposed areas need lifelong follow-up to identify cutaneous tumors at an early treatable stage.

Chronic radiodermatitis injury after cardiac catheterization.

The authors present two patients in whom chronic radiodermatitis developed after repeated cardiac catheterization and coronary angioplasty procedures, with no indication of malignancy. In one patient, after other therapeutic methods were unsuccessful in alleviating his symptoms, the authors excised the lesion with wide surgical margins and skin grafted the area. The mere purpose was to free the patient from the unrelenting pain and discomfort. In this case, the authors achieved complete success in wound healing but only partial success in pain relief.

Acute radiodermatitis from occupational exposure to iridium 192.

Industrial radiography using the man-made radioisotope iridium 129 is commonplace in the southern states. Despite established procedures and safeguards, accidental exposure may result in typical acute radiodermatitis. We have presented a clinical example of this phenomenon.

Melanocytic nevus with atypical dermoscopic features at the site of radiodermatitis.

BACKGROUND: Radiation therapy can cause acute and chronic damage of the skin. OBJECTIVE: A 71-year-old woman presented with an atrophic and sclerotic plaque at a site previously treated with radiotherapy because of lung cancer. Inside the area affected by chronic radiodermatitis, she reported that a preexisting pigmentary lesion had gradually undergone morphologic changes after radiation therapy. MATERIALS AND METHODS: On dermoscopy, the lesion showed features highly suspicious for malignant melanoma. The lesion was excised and examined histopathologically. RESULTS: The histopathologic diagnosis was compound congenital melanocytic nevus associated with prominent dermal sclerosis and epidermal atrophy. CONCLUSIONS: The existence of melanocytes within an atrophic and fibrotic area is a finding typically associated with recurrent or persistent melanocytic lesions. It is likely that the "pseudomelanoma" features of the lesion observed in our patient might have been secondary to the skin changes induced by radiation therapy.

[Thoracic radiodermatitis in interventional cardiology. Apropos of 6 cases].

The aim of this study is to describe thoracic radiodermatitis, a rare but not to be forgotten complication of interventional cardiology. The appearances are variable, from often oval-shaped erythema to cutaneous necrosis, with risk of chronic ulceration and malignant degeneration. The authors report 6 cases observed in 1997 after coronary angioplasty. Complex and long procedures are the main causes of this complication. Prevention requires a contribution from all the medical cardiological team, for the diagnosis, determining the indication of the type of revascularisation and for limiting the dose of X-radiation administered.

[Capillaroscopic and clinical correlations in chronic occupational radiodermatitis].

72 patients (69 M, 3 F) occupationally exposed to X-rays were subjected to a clinical and capillaroscopic evaluation so as to determine the morphological changes occurring within the skin and the microcirculatory system. The two parameters were correlated showing that microvasal lesions appear before clinical signs become evident. Therefore, the authors underline the importance of adding periodic capillaroscopic exams to the clinical control in order to prevent the occurrence of occupational chronic radiodermatitis.

Management of acute radiodermatitis. Pharmacological or nonpharmacological remedies?

The medical and nursing literature suggests a wide variety of pharmacological and nonpharmacological approaches to treatment of acute radiation skin damages (erythema, dry and moist desquamation, ulceration), but no specific and standardized therapy. The incidence of radiodermatitis has decreased with mega-voltage instruments, but it can nevertheless influence the therapeutic program and impair quality of life of patients. A study has been conducted to evaluate the tolerability and effectiveness of a nonpharmacological remedy, a mixture of hydrophobic (stearic acid) and hydrophilic (propylene glycol, glycerol, and polyunsaturated alcohols) components in a foam emulsion for the treatment of acute skin injuries following radiotherapy. Thirty-eight of 42 initial patients were evaluable: we observed a complete response in 22 (57.9%), improvement in 14 (36.8%), and failure in only two (5.3%).
