Tularemia presenting as tonsillopharyngitis and cervical lymphadenitis: a case report and review of the literature

In this report, we describe a 57-year-old woman with oropharyngeal tularemia who presented with tonsillopharyngitis and cervical lymphadenitis. Clinical and radiological manifestations and histopathological characteristics of this disease are discussed with a review of the world literature. The oropharyngeal form of tularemia should be considered in the differential diagnosis of cases involving tonsillopharyngitis and cervical lymphadenitis, particularly in those not responding to penicillin treatment.

CT assessment of the effect of fluticasone propionate aqueous nasal spray treatment on lower turbinate hypertrophy due to vasomotor rhinitis

Conclusion. Fluticasone propionate (FP) aqueous nasal spray was objectively found to be effective and safe for the treatment of lower turbinate enlargement in patients with vasomotor rhinitis. Objective. To assess the efficacy of FP aqueous nasal spray treatment in lower turbinate hypertrophy due to vasomotor rhinitis using CT. Material and methods. Of 35 patients with hypertrophic lower turbinates due to vasomotor rhinitis, 20 were treated twice daily with FP aqueous nasal spray (200 µg/day) for 3 months continuously and 15 were treated with placebo vehicle as a control group. The local effect of the nasal spray was studied using CT and visual analog scales. Results. Treatment with FP provided significantly greater relief from the symptom of nasal obstruction compared with placebo over the entire 3-month treatment period (p < 0.001). When the change from baseline was compared between the two groups, FP produced statistically significant reductions in the mucosal area of the lower turbinates and in the thickness of the nasal mucosa after 3 months (p < 0.05).

Volume of components of labyrinth: magnetic resonance imaging study.

Objective: To determine total inner ear fluid volume and cochlear and semicircular canal/vestibule volumes of a normal population to form a base for dimensional abnormalities of inner ear structures. Study Design: Cross-sectional. Setting: Academic otology and radiology practices. Patients: Twenty-nine healthy volunteers (13 male patients and 16 female patients with an average age of 31 yr) without any known history of intrauterine infection or any exposure to ototoxic agents and no abnormality at physical examination from the standpoint of hearing loss were included. Interventions: Twenty-nine volunteers underwent magnetic resonance imaging of the temporal region by means of thin-section T2-weighted sequences. The images were evaluated by the radiologist for the presence of any gross configurational abnormality. Fluid volume of each inner ear and components of labyrinth (cochlea, semicircular canals/vestibule) were calculated with the help of an online work station. Main Outcome Measure: To determine the volume of components of the labyrinth and total inner ear fluid, which may form a base for future studies about sensorineural hearing loss. Results: The volumes of total inner ear fluid, cochlea, and semicircular canals/vestibule were calculated. The mean and standard deviation of total inner ear fluid volume, cochlear volume, and semicircular canal/vestibule volume were obtained for each volunteer. Results were assessed with the help of statistical tests. Conclusion: There was no statistically significant difference between right and left inner ear fluid volumes of male and female subjects. There was also no statistical difference between right and left inner ear volumes when age and sex were not concerned. During evaluation of volumes according to sex, the difference between right and left inner ear fluid volumes was also assessed. Left semicircular canal/vestibule volume of female subjects were found to be higher than that of male subjects. The difference between right and left semicircular canal/vestibule volumes of female subjects was higher than the difference between right and left semicircular canal/vestibule volumes of male subjects.

Use of botulinum toxin type A for the treatment of masseteric muscle hypertrophy.

We investigated the effectiveness of botulinum toxin A intramuscular injection for the management of masseteric muscle hypertrophy. Five patients with masseteric muscle hypertrophy were treated with botulinum toxin A (Dysport, Beaufour Ipsen, France). Clinical photographs were obtained before and between 3 and 6 months after application. Four patients are pleased with their present facial appearance. However, one patient reported mild discomfort about his appearance. Neither local nor general adverse effects were noted. Botulinum toxin A is a safe, easy-to-use, and effective nonsurgical option in the management of masseteric muscle hypertrophy. Its use is associated with a high degree of patient and physician satisfaction.

Magnetic resonance imaging of cochlear modiolus: determination of mid-modiolar area and modiolar volume.

Modiolar deficiency has been reported as representing the mildest form of cochlear dysplasia. In this study the authors aimed to determine baseline values of the mid-modiolar area and modiolus volume in normal subjects. In this way they aimed to improve the detection of previously underdiagnosed subtle cochlear dysplasia in patients with sensorineural hearing loss.

Enophthalmos due to atelectasis of the maxillary sinus: silent sinus syndrome.

Silent sinus syndrome is a clinical entity with the constellation of progressive enophthalmos and hypoglobus due to gradual collapse of the orbital floor with opacification of the maxillary sinus, in the presence of subclinical maxillary sinusitis. It occurs secondary to maxillary sinus hypoventilation due to obstruction of the ostiomeatal unit. In this paper, a 35-year-old woman with a complaint of asymmetry in her left eye and denting of upper eyelid was reported. In the left eye, upper sulcus was deepened and there was 3-mm hypoglobus. There was no diplopia or restriction of eye movements in any gaze positions. Hertel exophthalmometry revealed a 4-mm enophthalmos on the left eye. Computed tomographic scan of the orbita and paranasal sinuses showed left maxillary sinusitis, air-fluid level, and collapse of left maxillary sinus walls. In addition, inferior bulging in the left orbital floor was also reported. The treatment was a 2-stage operation. In the first stage, she underwent endoscopic septoplasty plus left maxillary antrostomy, and in the second stage, she underwent a subciliary orbital floor repair of the iliac bone resulting in the improvement of the enophthalmos and her cosmetic appearance. Regarding this case, the literature is also reviewed in detail.

Mean Platelet Volume Decreases in Adult Patients With Obstructive Sleep Apnea After Uvulopalatal Flap Surgery.

Aim:The main purpose of the study was to investigate changes in mean platelet volume (MPV) values in patients with obstructive sleep apnea syndrome (OSAS) who had undergone uvulopalatal flap (UPF) surgery. Method:The study included a review of the medical records of 37 adult patients who had undergone UPF surgery after being diagnosed with OSAS. The baseline blood parameters of patients, including the MPV and platelet distribution width (PDW) values, were measured and repeated 3 months after treatment. Polysomnographic evaluations of the patients were also performed during admission and the 3rd month control. Comparisons of MPV values and their correlation with polysomnographic parameters were the main outcomes measured. Results:The blood parameters of all patients were similar except for MPV values, which were significantly lower after treatment (P < 0.001). Patients’ apnea hypopnea index (AHI) and apnea episodes were significantly reduced after the UPF surgery, whereas their oxygen saturation significantly increased (P < 0.001). The MPV values were not correlated with polysomnographic parameters (P > 0.05). Conclusion:The UPF surgery, which is a relatively simple surgical intervention to treat OSAS, alleviates nocturnal hypoxic episodes and lowers platelet volume. These may both be important predictors of adverse cardiovascular outcomes related to OSAS.

The Pitfalls and Important Distances in Temporal Bone HRCT of the Subjects with High Jugular Bulbs – Preliminary Report

BACKGROUND High jugular bulb (HJB) may be detected unilaterally or bilaterally in temporal bone high resolution computerized tomography (HRCT). OBJECTIVES In this retrospective study, we investigated the pitfalls and important surgical distances in patients with unilateral and bilateral HJB via temporal bone HRCT. MATERIAL AND METHODS In this preliminary report, the study group consisted of 20 adult patients (12 male, 8 female), or 40 ears, all of which underwent temporal bone HRCT. We divided them into groups that consisted of bilateral HJB (14 ears), unilateral HJB (13 ears), and control (No HJB, 13 ears). The anotomical relationships of the sigmoid sinus, jugular bulb, and carotid artery with several landmarks in the temporal bone were studied via temporal bone axial and coronal HRCT. The shortest distances between certain points were measured. These measurements were analyzed in respect to pneumatization. Dehiscence on the jugular bulb (JB) and internal carotid artery (ICA) and the dominance of JB were also evaluated for all of the groups. RESULTS In the axial sections of the temporal bone HRCTs, the sigmois sinus (SS)-external auditory canal (EAC) distance of the bilateral HJB group (14.00±1.17 mm) was significantly lower than that of the control group (16.46±2.14 mm). The JB-posteromedial points of the umbo on the ear drum (ED) distance of the bilateral HJB (6.28±1.72 mm) and the unilateral HJB groups (7.23±2.00 mm) were significantly lower than that of the control group (11.15±2.30 mm). In the coronal sections of the temporal bone HRCT, the JB-F distance of the bilateral HJB group (5.42±2.10 mm) was significantly lower than that of the control group (8.30±2.28 mm). As the mastoid pneumatisation and mastoid volume increased, the percentage of ICA-dehiscence and the percentage of JB-dehiscence increased. CONCLUSIONS In subjects with well-pneumatised mastoids, the doctors should be aware of the increased risk of ICA-dehiscence and JB-dehiscence. These measurements should be done in greater series to yield more thorough knowledge.

Risk of respiratory distress in the patients who were applied nasal packing at the end of nasal surgery

OBJECTIVE This prospective study investigated the risk of respiratory distress in the patients who were applied nasal packing at the end of nasal surgery; and effects of nasal packing on consciousness level while the patients were awake or asleep, measured by Bispectral Index (BIS). METHODS The study group consisted of 15 adult patients (10 male, 5 female), who were applied nasal packing at the end of nasal surgery. The control group consisted of 15 adult patients (10 male, 5 female), who received general anesthesia for various reasons. In the study and control groups, BIS index, respiratory rate, peripheral oxygen saturation, pulse per minute and blood pressure were measured at seven different times. RESULTS There was no statistically significant difference between BIS indexes of the study and control groups. In the fourth hour after sleep (AS-4h), respiratory rate of the study group was significantly lower than that of the control group. In the fourth hour after the anesthesia (AA-4h), oxygen saturation value of the study group was lower than that of the control group. CONCLUSION We conclude that in patients who are applied nasal packing at the end of nasal surgery; at AA-4h and AS-4h times, there may be risk of decrease in the oxygen saturation and respiratory rate parameters, respectively. Therefore, it is necessary to monitor non-invasive respiratory parameters and to give enriched oxygen by an oral catheter.

Is There a Relationship Between Optic Canal, Foramen Rotundum, and Vidian Canal?

Objectives:In this retrospective study, we investigated the relationship between paranasal sinus, optic canal, foramen rotundum, and vidian canal measurements. Methods:Computed tomographic (CT) images of 320 adult subjects and 640 sides (right and left) were used. Paranasal sinus dimensions, optic canal (OC), foramen rotundum (FR), vidian canal (VC), bilateral FR (FRFR), bilateral vidian canal (VCVC), VC-foramen rotundum (VCFR), and VC-optic canal (VCOC) distances were measured. Results:Right VCFR (6.06 mm), and right and left VCOC values (20.34 and 20.31 mm) of the males were significantly higher than those of the females (5.50, 18.91, and 18.80 mm, respectively). Foramen rotundum, OC, and VC values were positively correlated with each other. There was also positive correlation between FR width and maxillary sinus height. Increase of OC width was related to increase in FR width and area, VCVC distance; and decrease in maxillary sinus width. There was positive correlation between FRFR, VCVC, VCFR, and VCOC distance values. There was negative correlation between VC width and area; VCVC, VCFR, and VCOC distance; and maxillary sinus, ethmoid sinus, and sphenoid sinus measurement values. As these sinuses pneumatized more, VC width and area values decreased. Conclusion:As a conclusion, the paranasal sinus, OC, VC, and FR values showed relationship with each other. Before performing craniofacial and/or skull base surgeries, CT view should be taken to evaluate the localization and the course and dimensions of the OC and vidian nerve. It should be kept in mind that in the presence of more pneumatized paranasal sinuses in CT views, VC dimensions decreased.
