HIV-1 detection in the olfactory mucosa of HIV-1-infected participants.

Objective: HIV infection chronically affects the central nervous system (CNS). Olfactory mucosa is a unique site in the respiratory tract that is directly connected to the CNS; thus we wanted to evaluate olfactory mucosa as a surrogate of CNS sampling.

Design: We conducted a preliminary study examining HIV populations and susceptible cells in the olfactory mucosa.

Paclitaxel and carboplatin in neo-adjuvant and concomitant chemoradiotherapy in locally advanced head and neck squamous cell carcinoma.

Aim And Background: To evaluate feasibility of neoadjuvant chemotherapy (NA-CT) followed by CT + radiotherapy (RT) in locally advanced or unresectable head and neck squamous cell carcinoma (HNSCC).

Methods: 22 HNSCC patients were enrolled (18 males, 4 females; median age, 59.5 years; median ECOG PS, 1).

Detection of DNA adducts in human nasal mucosa tissue by 32P-postlabeling analysis.

Nasal epithelium is an easily accessible tissue that is potentially useful for human biomonitoring studies aimed at evaluating exposure to airborne carcinogens. We have devised a simple technique, which causes minimum distress to the informed patient, to obtain very small but sufficient biopsies from the inferior or middle turbinate head. DNA adducts were measured by 32P-postlabeling assay in nasal mucosa of nine cigarette smokers (including two subjects who had given up smoking shortly before sampling), two former smokers and 10 non-smoker healthy donors.

[Anterior craniofacial resection in the treatment of malignant nasal-paranasal sinus tumors with intracranial extension].

Nasal and paranasal sinus tumors extending through the cribriform plate to the overlying dura of the frontal lobe can be successfully treated by anterior craniofacial resection. During the period from 1986 to 1990, 14 patients (11 males, 3 females, age 18-67) with nasal/paranasal tumors extended to the nasal basis underwent craniofacial resection. From a histological point of view these patients were classified as follows: --8 adenocarcinomas --2 squamous cell carcinomas --2 esthesioneuroblastomas --1 cylindroma --1 haemangiopericytoma.

Topographic classification, clinical characteristics, and diagnostic delay of cancer of the larynx/hypopharynx in Torino, Italy.

The case series of a population-based case-control study of laryngeal and hypopharyngeal cancers in Torino, Italy, included 281 men with clinical and anamnestic data. Two hundred fifteen, 28, and 38 cancers originated from the endolarynx, epilarynx, and hypopharynx, respectively. Regions invaded by the tumor were divided into 26 subsites.
