Clinical TrialNitrous oxide-oxygen inhalation for outpatient otologic examination and minor procedures performed on the uncooperative child.
Otomicroscopic examination with suctioning of ears or other procedures is frequently uncomfortable especially for children. Anxiety and pain with lack of cooperation may result in trauma to the ear, incompletion of the examination, delayed diagnosis and treatment and need for completion of the examination under general anesthesia. The purpose of this study was to evaluate the efficacy and safety of utilizing nitrous oxide-oxygen inhalation for sedation and analgesia in otologic examination and minor surgical procedures performed on the uncooperative child at the outpatient clinic. ⋯ This pilot study shows the potential usefulness of nitrous oxide-oxygen inhalation administered by an otolaryngologist in the outpatient clinic. Alleviation of pain and anxiety and avoiding the need for physical restraint is an important goal that can be achieved with this form of sedation.

A tubeless anaesthetic technique for paediatric laryngeal laser surgery.
Laser surgery on the paediatric larynx requires cooperation between the surgeon and anaesthetist to carry out the procedure in the safest manner possible. Over a period of 3 years, 45 laser procedures have been undertaken on the upper airway of 14 patients at our institution. ⋯ In only one case, was a problem experienced with the technique, that of laryngospasm. The technique provides an unrivalled view of the larynx whilst allowing safe anaesthesia.

Comparative StudyComparison of cardiac function and valvular damage in children with and without adenotonsillar hypertrophy.
Comparison of cardiac function in children with and without adenotonsillar hypertrophy. ⋯ There was no significant difference in right ventricular function between the children with and without adenotonsillar hypertrophy. Whereas, there was shortening of tricuspid end-diastolic time in group I. However, five patients having adenotonsillar hypertrophy developed a cardiac dysfunction which was not observed in the control group. Therefore, we assumed a correlation between adenotonsillar hypertrophy and possible silent carditis following frequent tonsillitis.

The potential inflammatory role of arginase and iNOS in children with chronic adenotonsillar hypertrophy.
Nitric oxide (NO) induced tissue damage has been implicated in the pathogenesis of several diseases. Although recurrent/chronic tonsillitis and hypertrophy are still the most frequent surgical procedures carried out on children in order to cure these pathologies, etiopathogenetic mechanisms underlying these entities are still unknown. We aimed to investigate the potential inflammatory role of NO regulatory enzymes, arginase and inducible nitric oxide synthase (iNOS), in children with adenotonsillar hypertrophy. ⋯ The results of the present study supports that L-arginine:NO pathway may be key the participant in the pathogenesis of chronic adenotonsillar disease; arginase and iNOS activities are altered in children with adenotonsillar hypertrophy and this alteration improves after tonsillectomy.

Case ReportsThree-dimensional CT angiography imaging of vascular tumors of the head and neck.
To evaluate the utility of three-dimensional (3D) computerized tomography angiography (CTA) in head and neck vascular anomalies. ⋯ Three-dimensional CTA allows detailed description of vascular lesions of the head and neck and offers another effective means of imaging these complex lesions.
