The surgical management of recurrent acute and chronic barosinusitis in sports self-contained underwater breathing apparatus (scuba) divers.

PURPOSE: The aim of this retrospective study is to evaluate the feasibility of functional endoscopic sinus surgery (FESS) with supplementary surgical procedures in scuba divers with recurrent acute barosinusitis (RABS) and chronic barosinusitis (CBS). METHODS: In this retrospective study, 25 divers were classified into RABS (n:11) and CBS (n:14) groups. The presentation of divers have been reviewed. The PNS CT images were scored according to Lund-Mackay (L-M) system. A score has been assigned to the extent of endoscopic procedures performed. The outcome of surgery and life quality were determined by SNOT-22 and dive-related questions (DRQ) tests. RESULTS: The average L-M score was 3.8 ± 2 for RABS and 12.2 ± 3.4 for CBS groups. L-M score of CBS group was found to be statistically higher than RBS group (p < 0.05). The FESS score of CBS group (8.7 ± 2.4) was higher than RABS group (5.6 ± 2) which showed that the endoscopic sinus procedures were performed more extensively in CBS group (p < 0.05). The difference between the preoperative and postoperative SNOT-22 scores indicates that the degree of sinus symptoms improved better in RABS group than CBS group (p < 0.05). When DRQ test was evaluated, RABS group showed a better improvement in diving performance symptoms than the CBS group (p < 0.05). CONCLUSION: Our study demonstrated that divers with RABS and CBS can be managed successfully with FESS and supplementary surgical procedures. The improvement in the RABS group was superior to the CBS group, a difference attributed to the severity of chronic inflammation in CBS.

Surgery vs medical treatment in the management of PFAPA syndrome: a comparative trial.

BACKGROUND: Periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome is a common disorder in children but there is little or no consensus on its optimal diagnosis and management. OBJECTIVES: To compare the outcome of different management approaches - medical therapy or tonsillectomy. METHODS: The medical records of children diagnosed with PFAPA between 2008 and 2013 were retrospectively reviewed according to the modified Thomas test criteria. Patients were divided into two groups: group 1 for medical treatment - corticosteroids, a single intramuscular injection of methylprednisolone, and group 2 for surgery - tonsillectomy alone or tonsillectomy plus adenoidectomy .The course of the disease including the number and duration of episodes and the presence of remission, was documented. RESULTS: 105 patients (30 in group 1, 75 in group 2) met the study's inclusion criteria. Groups 1 and 2 were followed up for a mean (SD) of 23.6 (11.0) and 24 (10.3) months, respectively. At the end of the follow-up period, the number of episodes was 5.8 (6.3) vs 1.8 (1.9) (P<0.01) and their duration was 2.2 (1.3) vs 1.1 (0.8) days (P=0.03), both of which were significantly lower in group 2.The need for hospitalization during this period was significantly lower for group 2 at 1.1 (2.0) vs 0.1 (0.3) (P<0.01) and the remission rate in group 2 was significantly higher than in group 1 (98.6% vs 56.6%, P<0.01). CONCLUSION: This study demonstrated that surgery is superior to medical treatment for PFAPA in terms of increased remission rates and a decrease in the number and duration of episodes.

A case report of a malignant peripheral nerve sheath tumor of the oral cavity in neurofibromatosis type 1.

Patients with neurofibromatosis type 1 develop both benign and malignant tumors at an increased frequency. Most of the malignant peripheral nerve sheath tumors (MPNSTs) are considered as high-grade sarcomas originating from tissues of mesenchymal origin. It is generally accepted that MPNSTs occur in about 2% to 5% of neurofibromatosis patients. In this paper, we present a 16-year-old male patient with neurofibromatosis who developed MPNST of the retromolar area. The mass enlarged rapidly in a period of 6 weeks. The patient was treated surgically, and a tumor mass with a diameter of 7 × 6 × 4 cm was excised, but after 8 months a recurrence was observed at the same site. The sarcomatous change in a neurofibroma has an extremely poor prognosis, so patients with neurofibromatosis should be closely monitored for a possible malignancy. A rapid change in size of a preexisting neurofibroma, infiltration of the adjacent structures, intralesional hemorrhage, and pain indicate a possible malignant transformation to MPNST.

Temporomandibular disorders in scuba divers-an increased risk during diving certification training.

The design of a diving regulator's mouthpiece increases the risk of a temporomandibular disorder (TMD) in scuba divers. The total weight of a diving regulator is reflected directly on the temporomandibular joint, causing articular and periarticular disorders. In the current study, the prevalence of TMD in scuba divers triggered during diving certification training is investigated. We also aimed to determine the factors that lead to TMD during diving training and clarify the observation that there is an increased incidence of TMD in inexperienced divers. The study was held between 2006 and 2011. Ninety-seven divers were referred with the complaint of pain around temporomandibular area. The divers were classified according to their diving experience. Symptoms and signs of TMD were graded. Fourteen divers were diagnosed with TMD. Temporomandibular disorder was seen more frequently in inexperienced divers than in experienced divers (P = 0.0434). The most prevalent symptom was an increased effort for mouthpiece gripping. Temporomandibular joint tenderness and trigger point activation were the mostly seen physical signs. Thirteen divers had an improvement with therapy. The increased effort for stabilizing the mouthpiece is a recognized factor in TMD development. Attention must be paid to an association of scuba diving with TMDs, especially in inexperienced divers having a scuba certification training.

Chlamydia trachomatis tonsillopharyngitis.

Reports about the extragenital spread of Chlamydia trachomatis (CT) to oropharynx are limited. We report a male patient with progressive tonsillopharyngitis resistant to amoxicillin/clavulanic acid therapy. The patient presented 9 days after an orogenital and oroanal sexual intercourse with a female sex worker. The microimmunofluorescence revealed CT tonsillopharyngitis, and after completing a one-week course of doxycycline, the patient recovered completely. More cases of CT tonsillopharyngitis may be revealed if attention is paid to an association of sexual activity with enduring tonsillopharyngitis.

Comparison of transoral power-assisted endoscopic adenoidectomy to curettage adenoidectomy.

INTRODUCTION: The aim of this prospective and randomized study was to compare patients who underwent curettage adenoidectomy (CA) or transoral power-assisted endoscopic adenoidectomy (PAEA) performed as isolated procedures by a single surgeon over a period of 7 years. The success of an adenoidectomy has been evaluated by assessing the amount of reduction in the adenoid size and the symptomatic improvement at the sixth postoperative month. METHODS: Patients' nasal airway obstruction was graded by the parents of the patient on a visual analog scale (VAS), with a range from 0 to 10, with grade 10 representing total obstruction. The ratio of the choanal opening obstructed by an adenoid mass was measured and expressed in percentages as representative of the adenoid size. Preoperative and 6-month postoperative adenoid sizes were compared. RESULTS: Fifty-three patients (CA group 27 patients/PAEA group 26 patients) completed the study. In the CA group, VAS score improved from the preoperative score of 8.63 ± 0.88 to the 6-month score of 2.22 ± 1.01 (P < 0.0001); and in the PAEA group, the preoperative VAS score of 8.69 ± 0.84 improved to 2.08 ± 1.05 in the same period (P < 0.0001). No statistical significance was found when VAS score improvements were compared (P = 0.4569). The average ratio of choanal opening obstructed by an adenoid mass improved from the preoperative ratio of 89.41% ± 6.48% to the 6-month ratio of 7.85% ± 2.28% in the CA group; and the preoperative ratio of 90.19% ± 6.95% in the PAEA group improved to 3.65% ± 1.38% after 6 months. The reduction of adenoid size was significantly superior in PAEA than CA (P < 0.0001). The operative time in PAEA was significantly shorter than that in CA (P < 0.0001). CONCLUSION: Although symptomatic improvement at the 6-month follow-up is statistically indifferent, PAEA has been shown to be superior to CA with its superior performance in providing a near-total elimination of the adenoid mass in a shorter operating time.

Endoscopic endonasal management of cerebrospinal fluid rhinorrhea.

The authors review their 5 years' experience with endonasal endoscopic repair of the anterior skull base fistulas presenting with cerebrospinal fluid (CSF) rhinorrhea. A total of 12 patients were managed endoscopically between 2004 and 2008. Seven patients (58.3%) had nonsurgical posttraumatic CSF rhinorrhea, 2 patients (16.7%) had CSF rhinorrhea due to surgical/iatrogenic trauma, and 3 patients (25%) had spontaneous onset of CSF rhinorrhea. Radiosurgical correlation for CSF fistula identification was positive in all patients. The most common site of leak was the fovea ethmoidalis. The repair method consisted of an extradural underlay closure of a defect with fascia lata. The largest diameter of a defect to be closed was 15 mm. Immediate results were good in all patients, but later in the follow-up, CSF rhinorrhea recurred in 2 patients, and each patient had a revision 2 times. In the first revisions, transcranial approach was used, whereas in the second revisions endonasal endoscopic route was resorted. The primary closure rate was 83.3%, and the overall closure rate was 100%. The average follow-up period thus far is 21 months. Endonasal endoscopic technique well known to otolaryngologists should be considered as the first choice of surgery in the repair of CSF rhinorrhea because of low morbidity and a higher closure rate. The possibility of revision with the same technique makes this approach ideal for the repair of cranionasal osteodural defects.

Pleomorphic adenomas recurrences within the parapharyngeal space.

This study was undertaken to evaluate and concentrate on the recurrent pleomorphic adenomas (PAs) of the parapharyngeal space. The records of 9 patients treated for recurrent PAs occupying parapharyngeal space were retrospectively reviewed. The study population comprised 6 women and 3 men with a mean age of 51 (range, 35-79 years). Before the first revision surgery, imaging studies and clinical examinations showed 1 solitary mass in 4 patients, 2 solitary masses in 3 patients, and 3 or more masses in 2 patients. After first revision surgery, 4 patients had rerecurrences with multinodular disease. Two of 4 patients underwent radiation therapy (RT), and the other 2 patients underwent second revision surgery, among whom 1 patient underwent third revision surgery, and the other one was also submitted to RT. Overall, 12 reoperations were performed, and at the end of all operations, 4 patients had rerecurrences and residual disease. In conclusion, we recommend RT to patients with multinodular disease, known tumor spillage, and residual tumor in addition to revision surgery. Histopathologic features, surgical resection, relationship to surrounding vital tissues, and postoperative adjuvant radiotherapy are the most important determinants for recurrent PAs.

Primary malignant melanoma of the middle ear mucosa: a case report.

Primary involvement of the middle ear and mastoid mucosa by malignant melanoma (MM) has been rarely reported. We report an 81-year-old Caucasian woman presenting with otalgia, left-sided aural fullness, and hearing loss. Otoscopic examination revealed a purple-colored polyp that appeared to be vascular, occupy left external auditory canal (EAC). The computed tomography scanning showed a mass in soft tissue density, filling the tympanic and mastoid cavities, eroding the mastoid cortex, and invading medial and central parts of the EAC. A biopsy was performed with the diagnosis of MM. The patient underwent subtotal temporal bone resection with radical neck dissection. Dacarbazine was given postoperatively. The case presented herein emphasizes the need to be aware that MMs can arise in the middle ear and mastoid cavity. An index of suspicion in the differential diagnosis of temporal bone tumors is necessary for early recognition.

Determination of reactive oxygen species in nasal polyps.

A strong relationship between tissue damage and reactive oxygen species (ROS) has been established by previous studies. The aim of the current study was to evaluate the presence of ROS in nasal polyps (NP) by measuring luminol and lucigenin amplified chemiluminescence (CL). Three groups of specimens were studied. Group 1 composed of NPs of 15 patients, and group 2 constituted of healthy appearing nonpolypoid nasal mucosa of the same patients. Group 3 specimens (control group) were obtained from 15 patients who underwent septoplasty and/or inferior turbinectomy operations, and detected to be free of rhinosinusitis. None of the patients had a history of allergy, asthma, or aspirin sensitivity, and all patients showed negative results to a skin prick test. The ROS levels were measured directly with luminol and lucigenin amplified CL. CL measurements revealed significant differences between ROS constituents of NP (group 1) and control (group 3) tissue samples. CL measurements of healthy appearing nonpolypoid nasal mucosa (group 2) of the NP patients revealed values that were scattered between the values of the other two groups. Although insignificant, ROS levels of the nonpolypoid nasal mucosa (group 2) were found to be higher than normal controls (group 3). In this study, ROS levels of NP tissue samples were directly measured. In our study, by measuring high ROS levels in NP samples, a strong relationship between tissue damage in NPs and ROS has been demonstrated, and the contribution of ROS in the pathophysiology of nasal polyposis has been emphasized.

Basaloid squamous cell carcinoma of the larynx: a case report.

Basaloid squamous cell carcinoma (SCC) is a very rare, high grade, and aggressive variant of SCC, with a predilection for the upper aerodigestive system. Treatment should include surgery of the primary tumor and dissection of the cervical lymph nodes, followed by radiotherapy. We present a 50-year-old man with basaloid SCC of the supraglottic larynx, which was initially misdiagnosed as SCC. Supraglottic laryngectomy with bilateral radical neck dissection was performed, and radiotherapy was applied postoperatively. During a follow-up of 26 months, no evidence for recurrence was found. Basaloid SCC should be considered in the differential diagnosis of upper aerodigestive system malignancies because it has a distinct prognostic significance compared to conventional SCC.

Determination of reactive oxygen species in myringotomized tympanic membranes: effect of vitamin e treatment.

OBJECTIVES/HYPOTHESIS: Recent studies have established a strong relationship between the development of myringosclerosis and reactive oxygen species (ROS). The aims of the present study were to directly detect ROS in the tympanic membrane and middle ear mucosa of rats by measuring luminol amplified chemiluminescence, to evaluate the changes in the levels of ROS after treatment with vitamin E, and to examine the possible changes in the tympanic membranes otomicroscopically and histologically. STUDY DESIGN: Prospective controlled animal study. METHODS: Forty healthy Sprague-Dawley rats were divided into five groups of eight animals each. Animals in all groups except group 1 were bilaterally myringotomized. Group 2 received no treatment, group 3 was treated with topical olive oil, group 4 received topical vitamin E, and group 5 received intramuscular vitamin E. After 24 hours of myringotomy, tympanic membranes were examined otomicroscopically; thereafter, tympanic membranes and middle ear mucosa were peeled off. The right ears of the animals were used for biochemical assay, and the left ears were used for histological study. RESULTS: Reactive oxygen species levels were significantly decreased in group 4 with topical application of vitamin E compared with untreated and myringotomized animals in group 2. Reactive oxygen species levels were also decreased in group 5, although the decrease was not statistically significant when compared with groups 2 and 3. Histological studies confirmed sclerotic changes in the untreated myringotomized animals. The tympanic membranes of animals in groups 2 and 3 showed a white, chalk-like pattern of sclerotic changes, whereas animals in groups 4 and 5, with the exception of two animals in group 5, lacked these changes. CONCLUSION: Although the relationship between the development of myringosclerosis and ROS had been well documented previously, the present study is the first that has directly measured the levels of ROS in the tympanic membrane and middle ear mucosa. These results are relevant because they correlate with histological findings. It has also been demonstrated that topically applied vitamin E is effective in decreasing the ROS levels.

The effects of topical agents of fluticasone propionate, oxymetazoline, and 3% and 0.9% sodium chloride solutions on mucociliary clearance in the therapy of acute bacterial rhinosinusitis in vivo.

OBJECTIVES: The aims of the study were to determine: 1) how mucociliary activity in acute bacterial rhinosinusitis is affected; 2) how this activity is changed by therapy; 3) the effects of topical agents on mucociliary clearance, and 4) the most appropriate topical agent(s) to be used in the therapy of sinusitis. STUDY DESIGN: Five groups of patients with acute bacterial rhinosinusitis were studied prospectively. METHODS: All patients had 500 mg oral amoxicillin and 125 mg oral clavulanic acid preparations given three times daily for 3 weeks. According to the topical agent applications, these groups included: group I (n = 12), no topical treatment was given; group II (n = 14), two puffs for each nostril once daily of 50 microg/100 mL fluticasone propionate was given; group III (n = 9), one puff for each nostril three times daily of 0.05% oxymetazoline was given; group IV (n =12), 3% sodium chloride (NaCl) (buffered to pH 6.5-7 at room temperature) was given; and group V (n =13), 10-mL solutions of 0.9% NaCl (buffered to pH 6.5--7 at room temperature) were given for nasal irrigations three times daily. All patients had medication for 3 weeks and were controlled each week. The saccharin method was used to measure nasal mucociliary clearance. To investigate the early effects of the topical agents for groups II to V, an additional test was repeated 20 minutes after the basal mucociliary clearance recordings. The test was repeated in the first, second, and third weeks of the treatment. RESULTS: The mucociliary clearance was significantly slower in the acute bacterial rhinosinusitis group than in the control group. There was no significant difference between the basal mucociliary clearance and the 20th minute mucociliary clearance of the fluticasone propionate and 0.9% NaCl solution groups. The mean values of the basal and the 20 minute's mucociliary clearance of the oxymetazoline group were 24.72 +/- 6.16 and 15.5 +/- 7.45 minutes, respectively, which were statistically significant. The mean values of the basal and the 20th minute mucociliary clearance of the 3% NaCl solution groups were 19.45 +/- 9.35 and 15.45 +/- 8.20 minutes, respectively, which were also statistically significant. In the first group (without topical treatment), the basal mucociliary clearance became significantly shorter after the second week of treatment. In the first and second weeks of the treatment of the oxymetazoline group, the mucociliary clearance did not change significantly, but after the third week the mucociliary clearance was significantly shorter. In the 3% NaCl solution group, significant improvement began from the first week and continued through the third week. Comparing the basal and the third weeks' mucociliary clearance values among the groups, the oxymetazoline and 3% NaCl solution groups revealed more significant improvement than the other groups, but this improvement was not different from the improvement of group I. There was still a statistically significant difference in the mucociliary clearance of the post-treatment sinusitis groups from the control group. CONCLUSIONS: The oxymetazoline and 3% NaCl solution groups seemed to be more effective in mucociliary clearance, but there was no significant difference in improvement among the groups. The improvement of acute bacterial rhinosinusitis takes more than 3 weeks, according to the mucociliary clearance values of the groups.
