Is human saliva an indicator of the adverse health effects of using mobile phones?

Increasing use of mobile phones creates growing concerns regarding harmful effects of radiofrequency nonionizing electromagnetic radiation on human tissues located close to the ear, where phones are commonly held for long periods of time. We studied 20 subjects in the mobile-phone group who had a mean duration of mobile phone use of 12.5 years (range 8-15) and a mean time use of 29.

Squamous cell carcinoma of the oral tongue in patients over 75 years old.

Background And Aims: Squamous cell carcinoma (SCC) of the oral tongue is one of the most frequent head and neck cancers. The over-70-year age group is the fastest growing segment of the population. Age, however, is not considered a prognostic factor in oral tongue SCC.

Adaptation of median partial sternotomy in head and neck surgery.

Upper mediastinum involvement in diseases of the head and neck may require a sternal split. This study describes our adaptation of the upper median or "minimal" sternotomy technique for the treatment of head and neck pathologies. Between April 2002 and October 2005, 17 patients aged 4 to 82 years underwent minimal sternotomy in our institution for a variety of head and neck pathologies.

A comprehensive salivary analysis for oral cancer diagnosis.

Purpose: This study utilized comprehensive salivary analysis to evaluate biochemical and immunological parameters in the saliva of oral squamous cell carcinoma (OSCC) patients.

Methods: Whole saliva was collected from 25 otherwise healthy OSCC patients and compared to 25 healthy, age- and gender-matched individuals. All OSCC lesions were located at the lateral aspect of the mobile tongue.

Salivary analysis in oral cancer patients: DNA and protein oxidation, reactive nitrogen species, and antioxidant profile.

Background: Free radicals such as reactive oxygen species (ROS) and reactive nitrogen species (RNS), which induce oxidative and nitrative stress, are main contributors to oral carcinogenesis. The RNS (nitrosamines: nitrates, NO(3), and nitrites, NO(2)) are also produced by the reaction of ROS and other free radicals with nitric oxide (NO) and are therefore in equilibrium with it.

Methods: Whole saliva was collected from a group of 25 consenting oral squamous cell carcinoma (OSCC) patients and from a control group of 25 healthy age- and gender-matched individuals.

Thyroid cancer in children: management and outcome experience of a referral center.

Objective: To shed light on the discrepancy between the advanced stage at presentation and high recurrence rate of well-differentiated thyroid cancer in children and the overall good survival.

Design And Methods: The files of 75 children with well-differentiated thyroid cancer treated from 1954 to 2001 in a major tertiary-care hospital were reviewed for disease course, management, and outcome.

Results: Sixty patients (80%) had positive neck metastases with involvement of central compartment lymph nodes in all, lateral neck nodes in 36, and distant metastases in 4.

Adenoidectomy: long-term follow-up.

Objective: To assess the long-term (3-5 years) success of adenoidectomy and reasons for unsatisfactory results.

Study Design And Setting: The parents of all children who underwent adenoidectomy alone at a major tertiary center from 1998 to 2000 were asked to complete a questionnaire assessing their child's well-being and symptomatology 3-5 years after surgery; some were invited for follow-up. Symptom improvement, persistent symptoms, and adenoid regrowth were evaluated.

Concomitant analysis of salivary tumor markers--a new diagnostic tool for oral cancer.

Purpose: Oral squamous cell carcinoma (OSCC) is a common human malignancy. Circulatory epithelial tumor markers were previously investigated in the serum of OSCC patients but almost never in their saliva, in spite of the fact that there is a direct contact between the saliva and the oral cancer lesion. The purpose of the current study was to examine tumor markers in the saliva of OSCC patients.

Hyperfunctioning intrathyroid parathyroid gland: a potential cause of failure in parathyroidectomy.

Background: The surgical success rate of parathyroidectomy is 95%. However, in rare patients, ectopic hyperfunctioning parathyroid glands may be located in the thyroid but missed on imaging studies or during surgery. The aim of the present study was to evaluate the perioperative findings in 6 patients with intrathyroid parathyroid glands treated for hyperparathyroidism in our center over a 5-year period and to review the relevant literature.

Acute parotitis as a complication of fine-needle aspiration in Warthin's tumor. A unique finding of a 3-year experience with parotid tumor aspiration.

Objective/hypothesis: Fine needle aspiration (FNA) is an accurate, cost-effective tool for the study of salivary gland lesions. Although complications are extremely rare, salivary gland FNA can lead to hemorrhage, facial nerve injury, and cellulitis at the needle puncture site. Some studies suggest that FNA can cause infarction or metaplastic transformation of benign Warthin's tumors.

Seasonal variations in rhino-cerebral Mucor infection.

Objectives: Rhino-orbito-cerebral mucormycosis (ROCM) is an uncommon, potentially lethal infection that occurs mostly in immunocompromised hosts. The seasonal occurrence of ROCM was studied in two of Israel's largest medical centers.

Methods: A total of 36 patients were seen during a 25-year period in this retrospective bi-institutional cohort study.

Facial palsy associated with acute otitis media.

Objective: Facial palsy secondary to acute otitis media is rarely encountered today. The aim of the present study was to review the characteristics of the disease and propose the proper management.

Study Design: File review.

Squamous cell carcinoma of the oral tongue in young patients.

Objectives/hypothesis: Cancer of the tongue is reported with increasing frequency in young people. The objective of this work was to study the biologic and clinical course of the disease in this group. The clinical course of the disease in this patient group remains controversial.

The cytological and clinical value of the thyroid "follicular lesion".

Background: The main limitation of fine-needle aspiration (FNA) is its limited distinction between neoplastic and benign lesions. We summarize our experience with thyroid nodules that were defined as follicular lesions by comparing the clinical and cytological features of the thyroid follicular lesions that were examined histologically to define the most reliable criteria of malignancy.

Methods: The medical records of all patients who underwent thyroid aspiration at Rabin Medical Center from 1999 to 2000 were reviewed for a diagnosis of follicular lesion that warranted surgery (N = 58).

Revision parathyroidectomy guided by intraoperative radionuclide imaging.

Background: Technetium-99m sestamibi scintigraphy has become one of the most popular techniques for localization of the parathyroid gland after failure of primary neck exploration.

Objective: To examine the efficacy of sestamibi with the hand-held gamma ray detecting probe for the identification of parathyroid adenomas during revision parathyroidectomy.

Methods: We reviewed six cases of probe-assisted neck exploration for parathyroid lesions following unsuccessful primary exploration.

Subtotal parathyroidectomy: a possible treatment for calciphylaxis.

Calciphylaxis is a rare disorder in patients with chronic renal failure that is characterized by ischemic necrotic skin lesions. The prognosis is grave and mortality is high (80%). The precise mechanism of calciphylaxis is still unknown, but in addition to chronic renal failure, elevated parathyroid hormone levels appear to play a role.

Basaloid squamous carcinoma of the larynx.

Background: Basaloid squamous cell carcinoma (BSCC) is a distinct variant of squamous cell carcinoma that was first described by Wain et al in 1986. Since then, about 160 cases have been reported in the literature. Only 40 cases have been described in the larynx.

[Subglottic carcinoma].

Subglottic malignancies are rare. They constitute about 1% of laryngeal cancer. Most of these malignancies are squamous cell carcinoma.
