Evaluation of cervical lymphadenopathy in children: advantages and drawbacks of diagnostic methods.

Introduction: Cervical lymphadenopathy (LAP) in children is a common clinical diagnostic dilemma. The aim of our study was to analyse ultrasonography, fine needle aspiration biopsy, size and location on the neck to distinguish lymph nodes requiring excision from those that do not.

Material And Methods: We retrospectively studied 43 cervical lymph nodes that were excised from 43 children aged 0-16 years.

Adenosquamous carcinoma of the larynx associated with necrotizing sialometaplasia--a diagnostic challenge.

Necrotizing sialometaplasia is a benign, self-limiting, inflammatory process involving salivary glands, commonly associated with tissue ischemia. Clinically, necrotizing sialometaplasia is most often found in the hard palate as a deep ulcer with raised, indurated edges that can be indolent. This, as well as the histopathologic findings of necrotizing sialometaplasia, can be confused with those of a malignant neoplasm.

Levobupivacaine versus bupivacaine in epidural anesthesia for cesarean section. Comparative study.

Background And Objectives: Local anesthetic bupivacaine is found in two different enantiomers: levobupivacaine - S (-) and dextrobupivacaine - R (+). Based on studies showing that S(-) enantiomers are less cardiotoxic, their use has been increasing in clinical practice. This study aimed at comparing racemic bupivacaine and levobupivacaine in epidural anesthesia for elective cesarean section.

[Anesthesia for cesarean section in patient with von Willebrand's disease and HIV infection: case report.].

Background And Objectives: Von Willebrand's disease is the most common hereditary coagulation disorder in young women. The incidence of HIV infection among women has been progressively increasing, and vertical transmission may account for 25% of cases. This report aimed at describing the case of an HIV-positive patient with von Willebrand's disease scheduled for cesarean section.

[Comparison between 0.125% and 0.25% bupivacaine associated to fentanyl for epidural labor analgesia.].

Background And Objectives: Epidural analgesia aims at decreasing or even abolishing maternal suffering during labor. It is considered a safe and effective method for pain relief. This study aimed at comparing two bupivacaine concentrations (0.
