Atypical exanthems: morphology and laboratory investigations may lead to an aetiological diagnosis in about 70% of cases.

Background: Besides the six classical exanthems, other exanthems may occur, differing in morphology and causative agent (atypical exanthems). Their aetiological diagnosis is difficult but crucial for both the patient and community concerning issues such as time off school, immunizations, and risks for pregnant women and immunocompromised patients.

Objectives: To investigate whether morphology, associated symptoms and laboratory results can help to determine the aetiology of atypical exanthems.

Assessing hair shedding in children.

Background: The wash test is currently used to assess hair shedding, though it lacks a cut-off point of normality and any evidence of being reliable. The aim of this study is to provide data to fulfil those needs.

Methods: The wash test was employed in a standardized way on 31 children aged 3-11 years.

Argon laser treatment of cutaneous multiple angiokeratomas.

Background: Angiokeratomas are cutaneous vascular lesions with common clinical and histological features: dark red to black papules and ectasia of upper dermis vessels, respectively. Multiple angiokeratomas are difficult to treat because they are often too extensive for surgery and cautery, procedures frequently leading to hemorrhage and scarring.

Objective: Our report is designed to evaluate the efficacy of argon laser photocoagulation in the treatment of multiple angiokeratomas.
