RESUMO
Objective To analyze the clinical characteristics of and treatment outcomes for orbital apex lesions according to their pathological diagnosis and identify clinical characteristics that could aid in their differential diagnosis. Design Retrospective analysis design was used for this study. Setting The study was conducted in a single tertiary institution. Participants Patients with pathologically confirmed lesions centered in the orbital apex who were admitted between January 2011 and December 2015. Main Outcome Measures Clinical characteristics, including demographics, predisposing factors, presenting symptoms, radiological findings, intraoperative findings, biopsy results, and treatment outcomes. Results Nine patients with invasive fungal sinusitis, six with inflammatory pseudotumor, and six with neoplastic or tumorous lesions were enrolled. The most common presenting symptom was orbital pain or headache, followed by ophthalmoplegia and vision loss, which exhibited overall recovery rates of 62.5% and 33.3%, respectively, after definitive treatment. The prognosis was worse for patients with invasive fungal sinusitis. There was no significant difference in age, underlying medical conditions, absolute neutrophil count, C-reactive protein level, and radiological findings among the three groups. Grossly necrotic tissues around the orbital apex area at biopsy were more frequently found in patients with invasive fungal sinusitis than in the other patients. In most cases, pain ameliorated after surgical intervention. There were no surgery-related morbidities. Conclusions Lesions centered in the orbital apex included invasive fungal sinusitis, inflammatory pseudotumor, and tumorous lesions. However, clinical features that clearly differentiated chronic invasive fungal sinusitis from inflammatory pseudotumor could not be identified. Our findings suggest that prompt biopsy is warranted for timely diagnosis, symptom relief, and early implementation of definitive treatment.
RESUMO
OBJECTIVES: To clarify the common radiographic findings of audiologically documented prelingual single-sided deafness (SSD) and identify the prevalence of cochlear nerve deficiency (CND) in SSD infants referred from the newborn hearing screening program. METHODS: Between March 2012 and March 2017, the records of all infants referred to our otology clinic after undergoing newborn hearing screening program were retrospectively reviewed. Twenty-four consecutive well infants without risk factors who had a confirmed diagnosis of prelingual SSD under the age of 1 year and who underwent internal auditory canal (IAC) magnetic resonance imaging (MRI) were included. The sizes of cochlear nerve (CN), IAC, and cochlear nerve canal (CNC) were measured on MRI. The presence of CND was visually determined by comparing the CN size to the ipsilateral facial nerve (FN) in the affected side via an oblique sagittal view of IAC MRI and defined when CN was absent or smaller than FN. RESULTS: CND was seen in all 24 deaf ears (100%) on MRI. There was one with incomplete partition type I, and another with combined cochleovestibular nerve absence. Twenty-four subjects demonstrated either an absent (20/24, 83.3%) or small (4/24, 16.7%) CN. When the absent and small CN groups were compared, the former group had a higher prevalence of narrow CNC and narrow IAC. Of the 20 infants without identifiable CN on the affected side, 17 (85%) had narrow IAC and 17 (85%) had narrow CNC. In the 20 ears with absent CN, only one had both normal-sized IAC and CNC. CONCLUSION: The contribution of CND to prelingual SSD in Korean infants reached 100%, according to IAC MRI alone.

Bimaxillary surgery is the traditional treatment of choice for correcting class III malocclusion which is reported to cause an alteration of oropharyngeal structures and upper airway narrowing that might be a predisposing factor for obstructive sleep apnea (OSA). This study aimed to analyze sleep parameters in class III malocclusion subjects and ascertain the prevalence of snoring or OSA following bimaxillary surgery.A total of 22 patients with Le Fort I osteotomy and mandibular setback for class III malocclusion were prospectively enrolled. All patients received endoscopic examination, cephalometry, 3-dimensional computed tomography (3D-CT), and sleep study twice at 1 month before and 3 months after surgery.The patient population consisted of 5 males and 17 females with a mean body mass index of 22.5âkg/m and mean age of 22.1 years. No patients complained of sleep-related symptoms, and the results of sleep study showed normal values before surgery. Three patients (13%) were newly diagnosed with mild or moderate OSA and 6 patients (27%) showed increased loudness of snoring (over 40âdB) after bimaxillary surgery. According to cephalometric analysis and 3D-CT results, the retropalatal and retroglossal areas were significantly narrowed in class III malocclusion patients, showing snoring and sleep apnea after surgery. In addition, the total volume of the upper airway was considerably reduced following surgery in the same patients.Postoperative narrowing of the upper airway and a reduction of total upper airway volume can be induced, and causes snoring and OSA in class III malocclusion subjects following bimaxillary surgery.

In the present study, we intended to report a clinical pediatric case of thelaziasis in Korea. In addition, we briefly reviewed the literature on pediatric cases of thelaziasis in Korea. In the present case, 3 whitish, thread-like eye-worms were detected in a 6-year-old-boy living in an urban area and contracted an ocular infection known as thelaziasis incidentally during ecological agritainment. This is the first report of pediatric thelaziasis in Seoul after 1995.

OBJECTIVES: This research was conducted with an aim of determining the correlation between job insecurity and an employee's work-related health problems among permanent and temporary workers. METHODS: Using the data from the First Korean Working Conditions Survey conducted in 2006, a total of 7,071 workers, excluding employers and the self-employed, were analyzed. Work-related health problems were categorized as backache, headache, abdominal pain, muscular pain, stress, fatigue, insomnia, anxiety or depression. Each problem was then analyzed for its relationship to job insecurity through logistic regression analysis. RESULTS: Among the 7,071 workers, 5,294 (74.9%) were permanent workers and 1,777 (25.1%) were temporary workers. For the permanent workers, presence of high or moderate job insecurity appeared more closely linked to backache, headache, abdominal pain, muscular pain, stress, fatigue, insomnia, anxiety, and depression compared to absence of job insecurity. However, for the temporary workers, only depression appeared to be associated with the presence of high job insecurity. CONCLUSION: The study showed that the presence of job insecurity is correlated with work-related health problems. The deleterious effects of job insecurity appeared to be stronger in permanent than temporary workers. Additional research should investigate ways to effectively reduce job insecurity.
