Head and neck hemangiomas in pediatric patients treated with endolesional 980-nm diode laser.

Purpose: In pediatric patients with hemangiomas, vascular malformations, or lymphovenous malformations, therapeutic decisions frequently pose a challenge to surgeons, dermatologists, radiologists, and pathologists. We analyze the value of an interdisciplinary approach, and treatment of hemangiomas with an endolesional 980-nm diode laser.

Patients And Methods: Between 2000 and 2008 we provided interdisciplinary consultation for patients with hemangiomas, lymphangiomas, and vascular anomalies.

The use of the polymerase chain reaction and restriction fragment length polymorphism technique associated with the classical morphology for characterization of Lymnaea columella, L. viatrix, and L. diaphana (Mollusca: Lymnaeidae).

The specific identification of Lymnaeid snails is based on a comparison of morphological characters of the shell, radula, renal and reproductive organs. However, the identification is complicated by dissection process, intra and interspecific similarity and variability of morphological characters. In the present study, polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) techniques targeted to the first and second internal transcribed spacers (ITS1 and ITS2) rDNA and to the mitochondrial 16S ribosomal gene (16S rDNAmt) were used to differentiate the species Lymnaea columella, L.

Principles of transactional analysis.

Transactional analysis is part of a comprehensive system of individual and social psychiatry. It offers an indigenous approach to group therapy by making maximum therapeutic use of the tmsactions which continually lake place between those present. These transactions are analyzed into exteropsychic, neopsychic and archaeopsychic components, called colloquially Parent, Adult and Child, respectively.

[Band keratopathy. Symptomatological value based on 23 cases].

This study attempts to better define band keratopathy. A total of 23 eyes were reviewed, the largest sample ever published. The histopathology of this condition, characterized by lesions situated beneath the corneal epithelium, as well as its various clinical forms, are described.
