Comparison of pain after radiofrequency tonsillectomy compared with conventional tonsillectomy: a pilot study.

Tonsillectomy results in a severe sore throat, especially in the first few days, until the exposed and inflamed muscle becomes covered with regenerated mucosa. There are a variety of techniques of tonsillectomy including monopolar and bipolar diathermy, blunt dissection, and most recently radiofrequency tonsil ablation and coblation. The objective of the present study was to assess the postoperative pharyngeal or ear pain of radiofrequency tonsillectomy and compared with traditional blunt dissection tonsillectomy with loop ligation hemostasis.

The effect of mobile phone to audiologic system.

Mobile phones have come into widespread use. There are a lot of possible adverse effect to health. Use of mobile phone generate potentially harmful radiofrequency electromagnetic field (EMF) particularly for the hearing aspect. 98 subjects underwent hearing evaluations at Department of Otolaryngology, Faculty of Medicine, King Chulalongkorn Memorial Hospital, Chulalongkorn University. 31 males and 67females, mean age was 30.48 +/- 9.51 years old, all subjects were investigated the hearing level by audiometry, tympanometry, otoacoustic emission (OAE) and auditory brain stem evoked response (ABR). The average of using time were 32.54 +/- 27.64 months, 57 subjects usually used the right side and 41 the left side. Average time of use per day was 26.31 +/- 30.91 minutes (range from 3 to 180 mins). When the authors compared the audiogram, both pure tone and speech audiometry, between the dominant and nondominant side, it indicated that there is no significant different. When the authors focused on the 8 subjects that used the mobile phone more than 60 mins per day. It indicated that the hearing threshold of the dominant ears was worse than the nondominant ears.

Intermittent apnea and total intravenous anesthesia for microscopic laryngeal surgery.

Intermittent apnea with inhalational anesthesia has been reported to improve the visualization of the larynx but it has some disadvantages from inhalational anesthetics. The authors evaluated the use of total intravenous anesthesia instead of inhalation anesthesia in 30 patients undergoing microscopic laryngeal surgery. Anesthesia was started with propofol, fentanyl and cisatracurium. The patients were ventilated with 100% oxygen and the period of intermittent apnea, guided by pulse oximetry and end tidal carbon dioxide monitoring, was started by removal of the endotracheal tube. This technique provided a good visualization and immobile field for the operation. The average duration of apnea was 258 +/- 107 sec. The number of periods of apnea ranged from 1 to 4. A few patients showed some sympathetic responses to surgical stimuli. In conclusion, intermittent apnea with total intravenous anesthesia, with appropriate precaution, could be used without any serious adverse outcome for microscopic laryngeal surgery.

Aural aspergilloma: an unusual delayed complication of tympanoplasty.

Aural aspergilloma was first reported in 2001 by the authors. Recently the authors discovered a second case presenting with chronic otorrhea via a fistulous tract in the tympanic membrane. The patient was treated by removal of the fistulous tract and part of the tympanic membrane, cleansing the middle cavity, leaving the tympanic membrane perforated until obtaining a dry ear and followed by a tympanomastoidectomy, without the use of an antifungal agent. Because both cases of aural aspergilloma had a history of successful tympanoplasty with a long quiescent period before the symptoms appeared, the authors postulate that aural aspergilloma may be considered as an unusual delayed complication of tympanoplasty.

A comparative study of the side effects between pseudoephedrine in Loratadine plus Pseudoephedrine Sulfate Repetabs Tables and loratadine + pseudoephedrine tablet in treatment of allergic rhinitis in Thai patients.

The objective of the study was to evaluate the adverse reactions of Loratadine plus Pseudoephedrine Sulfate Repetabs Tables (LTD+PSE Repetabs) (Loratadine 5 mg + Pseudoephedrine 120 mg) twice daily with that of loratadine (5 mg) twice daily and pseudoephedrine (60 mg) quarter daily in the treatment of patients with allergic rhinitis. The study was designed as an investigator-blind, parallel group study. In this study, 56 patients were equally separated into 2 groups and treated for 14 days with either LTD+PSE Repetabs or loratadine + pseudoephedrine tablet. Both groups were comparable in age, gender, weight; baseline systolic blood pressure, diastolic blood pressure and pulse rate. The change of systolic blood pressure, diastolic blood pressure, and pulse rate did not reach clinical significance throughout the study period. There was no significant difference in occurrences of insomnia, palpitation, mouth dryness and anxiety. However, the incidence of patients with tremor at day 14 in the loratadine + pseudoephedrine tablet group was significantly higher than the LTD+PSE Repetabs group (39% vs 10.7%, p-value = 0.03). Furthermore, one patient in the loratadine + pseudoephedrine tablet group had to discontinue medication at day 7 due to insomnia. In conclusion, LTD+PSE Repetabs is well tolerated and has fewer adverse effects when compared to the loratadine + pseudoephedrine tablet.
