Variables affecting the occurrence of gastroesophageal reflux in obstructive sleep apnea patients

A number of recent studies have suggested that apnea and/or hypopnea episodes may be in a causal relationship with nocturnal gastroesophageal reflux (GER) episodes in obstructive sleep apnea (OSA) patients. In this study, we addressed the possible factors that may affect the occurrence of reflux events in OSA patients. For this reason, we investigated respiratory and sleep parameters in OSA patients with or without nocturnal GER episodes. Nineteen patients who were referred to the sleep laboratory for suspected sleep apnea were included in the study. All subjects underwent polysomnographic evaluation simultaneously with distal and proximal esophageal pH monitoring. During the recording period, a total of 134 reflux events, 134 from distal probes and none from proximal probes, were recorded. We divided patients into two groups: (1) nocturnal GER-positive patients (n=8; age: 41.9±11.9) and (2) nocturnal GER-negative patients (n=11; age: 45.4±3.3). We compared demographic, respiratory and sleep parameters between the two groups. Then we analysed the time relation between GER episodes and obstructive respiratory events. The two groups were matched by age and body mass index. Sleep and respiratory parameters were not different between the two groups. In conclusion, we suggested that age, body mass index and the severity of disease in obstructive sleep apnea patients are not effective determinants of gastroesophageal reflux. There is no sufficient evidence to accept arousals and obstructive apneas as primary causes of gastroesophageal reflux and vice versa. And finally, sleep macroorganisation has no impact on the occurrence of GER in OSAS.

Vasoconstriction and Analgesic Efficacy of Locally Infiltrated Levobupivacaine for Nasal Surgery

BACKGROUND: In this study, we compared the use of preincisional lidocaine 2% with epinephrine (LA) and levobupivacaine 0.25% plain (LB) for postoperative analgesia and vasoconstriction in patients undergoing nasal surgery. METHODS: Sixty patients were randomly assigned to receive preincisional local infiltration under general anesthesia. Group LB received levobupivacaine 0.25%, and group LA received epinephrine plus lidocaine 2% (add volume injected). Intraoperative hemodynamic changes, pre- and postoperative hemoglobin and hematocrit values were recorded. Visual analog scale values 30 min and 1, 2, 8, 12, and 24 h postoperatively and the need for rescue analgesic treatment in the first 24 h of all patients was recorded. RESULTS: At 30 min and 1, 2, 8, and 12 h postoperatively, visual analog scale values were lower in group LB than in group LA (P < 0.0001, P = 0.002, P = 0.023, P < 0.0001, and P = 0.011, respectively). The analgesic requirement was significantly lower in group LB when compared with that in group LA (P = 0.038). Group LB had significant differences between preoperative and postoperative hemoglobin and hematocrit values (P = 0.014 and 0.025). Group LA had significant differences between preoperative and postoperative hemoglobin and hematocrit values (P = 0.031 and 0.024). CONCLUSIONS: We conclude that postoperative analgesia in nasal surgery with local infiltration of levobupivacaine was significantly more potent and longer lasting than that achieved by lidocaine plus epinephrine.

Does topical ropivacaine reduce the post-tonsillectomy morbidity in pediatric patients?

OBJECTIVES To determine whether post-operative administration of topical ropivacaine hydrochloride decreases morbidity following adenotonsillectomy. STUDY DESIGN Prospective, randomized, double-blind clinical trial. SETTING University referral center; ENT Department. PARTICIPANTS Fourty one children, aged 4-16 years, undergoing tonsillectomy. METHODS Patients received 1.0% ropivacaine hydrochloride soaked swabs packed in their tonsillar fossae while the control group received saline-soaked swabs. Mc Graths face scale was used to compare the two groups in respect of pain control. Chi-square and two-tailed unpaired Students t-tests or Mann-Whitney-U-tests were used to compare the two independent groups. As 10 we made 11 comparison between groups, for Bonferroni correction, p<0.005 was accepted as statistically significant. RESULTS Only first hour there was no significant pain-relieving effect seen in the ropivacaine group (p>0.05). The other hours and days there were statistically significance between the two groups (p<0.001). Also, the other post-operative parameters such as nausea, fever, vomiting, odor, bleeding, otalgia and trismus were not statistically different between the two groups. There were no complications associated with ropivacaine hydrochloride. No patients in this study suffered systemic side effects related to the use of this medication. CONCLUSION Locally 1.0% ropivacaine administration significantly relieves the pain of pediatric tonsillectomy and, it is a safe and effective method. High concentrations of ropivaciane may produce clinically significant pain relief. It is more effective to reduce of post-operative analgesic requirement after first hour.

Etiology of deafness at the Yeditepe School for the deaf in Istanbul

OBJECTIVE The etiology of deafness can be classified as genetic, acquired and unknown. An unknown etiology was a high incidence in previous reports. The aim of this study is to explore the etiology of deafness and to reduce the cases in the unknown group. METHODS This study was conducted on 162 students at the Yeditepe School for the deaf. Otologic, physical and psychological examinations were performed by a team of doctors including four otologists, a geneticist, a dentist, an ophthalmologist and an audiologist. RESULTS A genetic cause was identified in 41.35%, acquired 37.65% and unknown 20.98%. Genetic etiologies were stratified as familial and syndromic subgroups. A familial cause was found in 60 of 162 children and in 22 of those 60 cases, the parents had a consanguineous marriage. There was 11 cases associated with a syndrome. Ninety four minor abnormalities have been established in some deaf children. Febrile convulsion (36%) was identified as the most common etiology in acquired cases. CONCLUSION In contrast with other studies the consanguineous marriage was present in 36.6% of the familial cases and 38.8% in total of the school. An unknown etiology was reported in high rates in previous reports. These unknown cases could be described as a part of a syndrome by a crowded team of consultants. Evaluation of early diagnostic criterias and minor abnormalities can help us to provide early rehabilitation of deafness in childhood.

Lipoid proteinosis of the larynx.

Lipoid proteinosis is a rare disease that presents with hyaline deposits in many tissues. It involves predominantly the skin and upper aerodigestive tract, presenting with small yellowish papules and hoarseness. It may involve the central nervous system and cause intracerebral calcifications. Laryngeal lesions may resemble singers nodule or chronic laryngitis. The pathogenesis of the disease is not clear although several studies suggest a defective collagen production and/or lysosomal storage disease. In this article two cases with skin and larynx involvement are reported.

Congenital hairy polyp of the soft palate.

Hairy polyp is an unusual developmental malformation that is most frequently seen as a pedunculated tumor in the neonate. They are benign lesions containing elements of both ectodermal and mesodermal origin. The symptoms of hairy polyps relate both to their location and their size. Larger lesions produce symptoms due to feeding difficulties and airway obstruction while smaller lesions cause intermittent symptoms resulting from a ball-valve type of obstruction. We present two cases of a soft palate hairy polyp causing respiratory and feeding difficulties and review the literature.

A case of oculoglandular tularemia resistant to medical treatment.

Abstract Tularemia is a zoonotic disease of the northern hemisphere. Oculoglandular tularemia is the rarest form, comprising 1.4–4.2% of all cases. We present a patient with oculoglandular tularemia that did not respond to gentamicin to demonstrate the need for prolonged antimicrobial treatment and surgical intervention.

Primary malignant melanoma of the pharynx

Primary mucosal malignant melanomas are rare. They appear late in life and their prognosis is grave. Although there is no consensus on therapy, wide surgical resection followed by radiotherapy, chemotherapy and immunotherapy are treatment modalities. In this report we present a case of widespread primary mucosal malignant melanoma located in the pharynx. After immunotherapy (four cycles of interleukin-2 and interferon-alpha) and chemotherapy (four cycles of cisplatin and dacarbazine) has been applied as primary therapy for suppression of the mass, transoral total pharyngeal resection was performed. After surgery three cycles of immunotherapy and three cycles of chemotherapy were administered followed by radiotherapy (total dose of 6600 cGy). An additional three cycles of immunotherapy and chemotherapy were administered. Although no local recurrence was observed during the 14 months of follow-up after the completion of radiotherapy, cranial and lung metastasis were detected in the 12th month.

Relation of Isolated Tonsillar Hypertrophy with Body Mass Index

Objective: The purpose of this study was to investigate the relationship between tonsillar hypertrophy and body mass index (BMI). Material and Methods: This is a cross-sectional study which was conducted in three primary schools located in Duzce. A total of 1,282 children between 7 and 12 years of age were evaluated and the size of their tonsils was investigated with regard to height and weight. This study was performed in the course of school screening, and the correlation between estimated tonsil size and BMIs of the children was investigated. Results: Sixteen of 1,282 students were excluded from the study, leaving 1,266 children in the study. The mean (±SD) age of the children was 9.13 ± 1.45 (range 7–12) years. The mean height of the 1,266 children was 129.07 ± 9.95 (range 105–163) cm, the mean weight was 28.81 ± 6.96 (range 15–68) kg, and the mean BMI was 17.09 ± 2.33 (range 12.07–30.0) kg/m2. There was no statistically significant effect of tonsil size on BMI. We could not find a significant relation of isolated tonsillar hypertrophy with BMI. Conclusions: No relation could be found between tonsillar hypertrophy and BMI.
