Oral propranolol in the treatment of proliferating infantile haemangiomas: British Society for Paediatric Dermatology consensus guidelines.

Background: Infantile haemangiomas (IH) are the most common vascular tumours of infancy. Despite their frequency and potential complications, there are currently no unified U.K.

Predicting complications with pretreatment testing in infantile haemangioma treated with oral propranolol.

Background: Since 2008, orally administered propranolol has rapidly gained acceptance as the preferred therapy for haemangiomas, and is usually initiated by ophthalmologists, dermatologists or plastic surgeons who do not routinely use propranolol for any other indication. During the initial years when experience was limited, most healthcare professionals justifiably adopted a cautious approach when initiating and monitoring treatment. A consensus recommendation from the American Society of Dermatologists suggests routine observation, monitoring and cardiology assessments prior to propranolol initiation.

Propranolol in the treatment of infantile haemangiomas: lessons from the European Propranolol In the Treatment of Complicated Haemangiomas (PITCH) Taskforce survey.

Background: Oral propranolol is widely prescribed as first-line treatment for infantile haemangiomas (IHs). Anecdotally, prescribing practice differs widely between centres.

Objectives: The Propranolol In the Treatment of Complicated Haemangiomas (PITCH) Taskforce was founded to establish patterns of use of propranolol in IHs.

Propranolol for infantile haemangiomas: a review.

Infantile haemangiomas are the most common benign tumour of infancy. However the majority are self-resolving and only a small minority of cases require treatment, with various different medications being used in the past. Over the last few years, propranolol, a non-selective β-blocker, has become a popular and successful treatment for infantile haemangiomas.

Degos disease: a new simulator of non-accidental injury.

Recent high-profile cases have made paediatricians very aware of the serious implications of either missing or wrongly diagnosing non-accidental injury. Subdural fluid collections in non-mobile infants usually represent haemorrhage caused by non-accidental injury. We report a 6-month-old male who presented to the Accident and Emergency Department of Birmingham Heartlands Hospital with bilateral subdural fluid collections and skin ulcers resembling cigarette burns.

Review of modern techniques in detecting port-wine stain response to laser therapy.

Background: Traditional mechanisms of assessing port-wine stain response to laser therapy have rested mainly on subjective determinations by physician and patient. However, the wide variation in treatment response poses a profound need for objective devices to measure treatment outcomes so that maximum effectiveness of therapy can be achieved without unnecessary repeat treatments.

Objective: The purpose of this paper will be to review noninvasive techniques to measure port-wine stain response to laser therapy.

Epidermal Langerhans cell apoptosis is induced in vivo by nonanoic acid but not by sodium lauryl sulphate.

Exposure to irritants may cause chronic irritant contact dermatitis (ICD), characterized by irregular epidermal thickening and a predominantly dermal mononuclear cell infiltrate. The mechanisms involved, and why only certain individuals are affected, are not clearly understood. Different irritants may trigger different cellular and molecular interactions between resident skin cells and recruited inflammatory cells.

Accumulation of p53 is associated with tumour progression in cutaneous lesions of renal allograft recipients.

Renal allograft recipients suffer from a markedly increased susceptibility to premalignant and malignant cutaneous lesions. Although various aetiological factors have been implicated, little is known of the associated genetic events. In this study we initially employed immunocytochemical techniques to investigate the prevalence and localisation of accumulated p53 in over 200 cutaneous biopsies (including 56 squamous cell carcinomas) from renal allograft recipients and immunocompetent controls.

Changing forms of juvenile pityriasis rubra pilaris--a case report.

Pityriasis rubra pilaris (PRP) is a rare disease affecting both males and females. The aetiology is unknown, but it has an ill-defined relationship with psoriasis. Within the spectrum of PRP certain disease patterns are recognized, and regarded by many as helpful prognostic indicators.

Intravascular histiocytosis.

The majority of cases of intravascular lymphomatosis are B-cell lymphomas with only the occasional case being of T-cell type. We report a case of intravascular lymphomatosis in which the proliferating cells were of histiocytic type; the tumour has recurred following treatment.

Prevalence of human papillomavirus DNA in cutaneous neoplasms from renal allograft recipients supports a possible viral role in tumour promotion.

It is well established that renal allograft recipients (RARs) have an increased incidence of viral warts and premalignant and malignant cutaneous lesions, and the risk of their development increases in proportion to duration of graft survival. It has been postulated that, in addition to the effects of prolonged immunosuppression and previous sun exposure, human papillomaviruses (HPV) may also contribute to the carcinogenic process. In this study, the prevalence of HPV DNA was examined in a range of premalignant and malignant cutaneous tumours from 50 immunosuppressed patients (47 renal allograft recipients plus three cardiac allograft recipients) and 56 immunocompetent patients using Southern hybridisation as a low-stringency screening method and type-specific polymerase chain reaction (PCR) assays for eight HPV types.

Possible relationships between changes in body weight set-point and stress metabolism after treating rats chronically with D-fenfluramine. Effects of feeding rats acutely with fructose on the metabolism of corticosterone, glucose, fatty acids, glycerol and triacylglycerol.

Rats were maintained on a corn oil diet and treated with D-fenfluramine at doses of 2.5 mg/kg twice a day for 11 days or with 10 mg or 25 mg/kg once a day for 12 days. The lower dose of D-fenfluramine produced no marked changes in body weight and after 11 days of treatment the weights of the rats on average were only 2% lower than the controls.
