    ABSTRACT: Our objective was to investigate the efficacy of intramuscular injection and peritonsillar infiltration of tramadol to prevent pain in children undergoing tonsillectomy. In a double-blinded trial, 45 children were randomized into three groups: infiltration anesthesia with tramadol (2 mgkg(-1)) to the peritonsillar area (INF group, n=15), intramuscular analgesia with tramadol (2 mgkg(-1)) (IM group, n=15), and the placebo controls (PL group, n=15). Visual analog scale (VAS) scores for pain assessment, heart rate (HR) and mean arterial pressure (MAP) during and after anesthesia were recorded. Mean HR values were higher in INF than PL group at 10th, 20th, and 30th minutes of operation (P<0.05). Nine children required analgesics within the first hour after surgery in PL compared to 1 child in INF group (P=0.036). VAS scores on awakening were significantly better in INF than PL group (P=0.015). The difference between IM and PL groups was not significant for any of the parameters. Peritonsillar infiltration with tramadol provided good intraoperative analgesia, less postoperative pain on awakening and lower analgesic requirement within the first hour after surgery.

    ABSTRACT: There are only few reports describing the texture of the inferior turbinate bone in normal and pathologic conditions. In this study, different types of human inferior turbinate bones were classified and radiological features of each type were defined. The shape, structure and density of the inferior turbinate bones were evaluated using paranasal sinus computed tomography images of 283 patients. The cross-sectional areas of the bony part of the inferior turbinate were measured in bone windows. Human inferior turbinate bones were classified into four groups on the basis of different shape and structure as: Type I, lamellar; Type II, compact; Type III, combined type (compact with spongious component); Type IV, bullous. The distribution was as follows: 352 (62.19%) lamellar, 50 (8.83%) compact, 162 (28.63%) combined, and 2(0.35%) bullous type. Inferior turbinate bone is not in a uniform shape and structure. These diversities should be taken into consideration in radiological and clinical evaluation.

    ABSTRACT: The purpose of this study was to analyze the effect of coal dust particles on nasal mucociliary function in coal mine workers. Using the saccharin method, nasal mucociliary clearance was determined for 77 subjects, of which 39 who worked in a coal mine were actively exposed to coal dust whereas 38 were unexposed control subjects. The measurements were performed in the coal mine, at the level of 170 m below sea level. The average saccharin nasal transit time in coal mine workers, 12.61 (SD: 4.30) minutes, is longer than that of the control subjects, 10.97 (SD: 3.22). Although the findings of this study demonstrate that the coal particles affect the nasal mucociliary clearance, the difference in saccharin nasal transit time between the two groups (exposed vs unexposed) is not statistically significant (P = 0.063).

    ABSTRACT: In this article, a Wohlfahrtia magnifica otomyiasis case, a 31-year-old, non-mentally retarded patient who had undergone radical mastoidectomy previously is presented. Maggots in the radical mastoidectomy cavity were removed then topical treatment was applied. The maggots were identified as W. magnifica. In cases of myiasis, identification of larvae following direct extraction and application of preventative methods is essential.

    ABSTRACT: To test whether mebendazole, an antiparasitic drug, would affect recovery from halitosis. We conducted a randomized, double-blind, placebo-controlled trial between April 1999 and September 2001. A referral medical center. One hundred sixty-two children aged 5 to 16 years whose parents complained about their chronic bad breath. Children were randomly assigned to receive mebendazole (n = 82) or placebo (n = 80). Parents whose children had halitosis were evaluated for halitosis at 2 months of treatment by questionnaire. The microbiologist investigated the stool samples of children for parasitosis at the beginning of the trial and also at the end of the trial in children who were treated with mebendazole. Among those children who had evidence of parasites in stool samples at the beginning of the trial, 18 of 28 who were treated with mebendazole recovered from halitosis, compared with 2 of 24 who received placebo (relative risk [RR] for recovery, 7.7; 95% confidence interval [CI], 2.0-29.9). Among those who did not have stool parasites, 14 of 52 improved with mebendazole, compared with 10 of 48 taking placebo (RR, 1.3; 95% CI, 0.6-2.6). Mebendazole intake made a significant difference whether or not the children had parasites (P =.002). Parasitosis should be considered as a possible cause of halitosis in the pediatric patient population. Mebendazole therapy seems to offer benefit to those children with parasites as a potential cause of their halitosis.

    ABSTRACT: To evaluate the unilateral compensatorily hypertrophied inferior turbinate (CHIT) by computed tomography (CT) and determine the enlargement of the bone component in different parts of the CHIT. Patients were studied in three groups: those with a straight or nearly straight septum (n = 143), with mild deviation (n = 42), and with moderate to severe deviation (n = 99). The cross sectional area (CSA) of the inferior turbinate (IT) bone and the whole turbinate were measured at anterior, middle, and posterior thirds of the IT in coronal sections. The ratio of CSA of the IT bone on two sides of the septum (interturbinate ratio) and the ratio of the CSA of the overall turbinate to the IT bone (intraturbinate ratio) were calculated. The interturbinate ratio of the bony turbinate CSA for the severe deviation group was significantly higher compared with other groups in anterior and middle segments (p < 0.0001). The intraturbinate ratio was highest in the posterior segment and lowest in the middle segments in compensatorily hypertrophied sides for all groups (p < 0.001). Skeletal enlargement is prominent in anterior and middle thirds of CHIT in patients with pronounced septal deviation.
