The role of factor V Leiden and prothrombin G20210A mutations in sudden sensorineural hearing loss.

OBJECTIVES: To investigate the incidence of factor V Leiden and prothrombin G20210A in sudden sensorineural hearing loss patients. STUDY DESIGN: The patient group for this study was selected prospectively in the case of 28 patients and retrospectively in the case of another 28. SETTING: Tertiary referral center. PATIENTS: Fifty-six patients (29 female, 27 male) with sudden sensorineural hearing loss (SSHL) and 95 control subjects (48 female, 47 male) were enrolled in this study. The age of the control subjects were between 26 and 76 (38 +/- 16.7), and that of the patients were between 10 and 87 (42.6 +/- 18.2). INTERVENTION: The factor V Leiden and prothrombin G20210A mutations were detected by rapid polymerase chain reaction amplification of genomic DNA extracted from the SSHL patients' peripheral blood cells. MAIN OUTCOME MEASURE: Thrombotic microangiopathic disorders are characterized by widespread microvascular thrombosis leading to end-organ injury. The mutations of factor V Leiden and prothrombin gene are known as genetic risk factors for thrombotic microangiopathy in normal patients. SSHL may occur with occlusion of the cochlear blood supply by microthromboangiopathy. RESULTS: Factor V Leiden mutation was found to be higher in SSHL patients when compared with control subjects (16.1% vs 5.3%). The difference between the two groups was found to be statistically significant (p = 0.02). However, statistical significance was not found between the groups in regard to prothrombin G20210A mutation. Factor V Leiden and prothrombin gene mutations were heterozygous in all of the subjects. CONCLUSION: A significant association between factor V Leiden mutation and idiopathic SSHL could be shown in this study. There was no correlation, however, between the occurrence of idiopathic SSHL and prothrombin mutation.

Comparison of morphine and tramadol by patient-controlled analgesia for postoperative analgesia after tonsillectomy in children.

BACKGROUND: Tramadol is an alternative to other opioids for postoperative pain management. This prospective, randomized, double-blind study was designed to compare the analgesic efficacy of patient-controlled tramadol with patient-controlled morphine for postoperative pain after tonsillectomy in children. METHOD: Sixty patients were allocated randomly to receive a patient-controlled analgesia (PCA) with either tramadol (T) or morphine (M), in a double-blind randomized study. When surgery was completed and hemostasis achieved, a standardized loading dose (0.1 mg.kg(-1) in group M, or 1 mg.kg(-1) in group T) was given. Thereafter, the children helped themselves to bolus doses (morphine (0.02 mg.kg(-1)) or tramadol (0.2 mg.kg(-1)) with lock-out times of 10 min without time limit via a PCA device. Scores for pain, sedation, nausea, and the bolus and total PCA doses, hemodynamic parameters and side effects were recorded at 5, 15, 30 min and 1, 2, 4, 6 and 24 h during PCA administration. RESULTS: Pain scores decreased significantly with time in both groups (P < 0.05), but were lower in group M than in group T at 1, 2 and 4 h (P < 0.05). Sedation scores increased with time in both groups (P < 0.05). However there were no significant differences in sedation scores between two groups at any study period, but nausea scores were higher in M group at 4, 6 and 24 h (P < 0.05). CONCLUSION: Intravenous patient-controlled tramadol is an alternative to patient-controlled morphine for postoperative pain relief in children after tonsillectomy. Morphine gave better postoperative pain relief, but was associated with a higher incidence of nausea than tramadol.

The role of food allergy in otitis media with effusion.

OBJECTIVE: To detect the relationship between food allergy and otitis media with effusion (OME). MATERIALS AND METHODS: This study was performed on three different groups. The patient group was made up of 56 patients with OME (group I). There were 28 patients with food allergy in group II and these patients were investigated for OME. The control group consisted of 28 patients without any complaints concerning food allergy or OME (group III). RESULTS: Food allergy was detected in 25 patients with OME (44.6%) (group I). In patients with food allergy (group II), OME was detected in 7 patients (25%). In the control group (group III) food allergy was diagnosed in 5 patients (18%) and OME in 1 patient (3%). The incidence of food allergy in OME group was statistically significant when compared to the normal group (P > 0.05). CONCLUSIONS: This study demonstrates that food allergy may play a role in the etiopathogenesis of OME.

Vallecular cyst: a cause of failure to thrive in an infant.

Congenital vallecular cyst is fairly uncommon in neonates and infants. Although benign in nature, it may cause stridor and even life-threatening airway obstruction in early infancy. A 3-month-old male baby presented with failure to thrive and respiratory distress was found to have a vallecular cyst. Marsupialization with CO(2) laser was performed.

A neonate with malignant ectomesenchymoma.

Malignant ectomesenchymoma is a rare tumor reported in head-neck, abdomen and perineal regions. It consists of mesenchymal and neuroectodermal elements. In this tumor group, neoplastic cells are differentiated into neuronal cells. It also has at least one malignant mesenchymal element, generally rhabdomyosarcoma. In this report we present a neonate with ectomesenchymoma.
