Therapeutic Outcome of Primary Snoring and Mild Obstructive Sleep Apnea and Clinical Suggestion for Treatment Approaches / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES@#The clinical significance and need for the treatment of primary snoring and mild obstructive sleep apnea have been recently questioned. In this study, we analyzed therapeutic outcome and the methods of treatment of such diseases.SUBJECTS AND METHOD: A retrospective review was conducted using the medical records of patients diagnosed with primary snoring or mild obstructive sleep apnea at a single institution from 2013 to 2015 through polysomnography or WATCHPAT.@*RESULTS@#Of the 18 patients (37%) with primary snoring, 13 patients (72.2%) underwent surgery, four patients (22.2%) were treated with surgery and mandibular advancement device, and one patient (5.6%) underwent automatic positive airway pressure therapy. Of the 78 patients (61%) with mild obstructive sleep apnea, 35 patients (44.8%) had surgery, 24 patients (30.8%) were treated with mandibular advancement device, 13 patients (16.7%) were treated with surgery and mandibular advancement device and 6 patients (7.7%) received automatic positive airway pressure therapy. For primary snoring, while Epworth Sleepiness Scale and Pittsburg Sleep Quality Index did not improve, the snoring visual analog scale decreased significantly. In patients with mild obstructive sleep apnea, Apnea-Hypopnea Index, snoring decibel, Epworth Sleepiness Scale, and Pittsburg Sleep Quality Index were significantly decreased after treatment and the lowest oxygen saturation was significantly increased after treatment.@*CONCLUSION@#For primary snoring, the direction of treatment should be determined in accordance with the presence of associated diseases related to sleep disturbance breathing. For mild obstructive sleep apnea, active treatment may be helpful.

Clinical Application and Updates on Vestibular Evoked Myogenic Potential: Proposal for Future Development in Vestibulopathy / 대한평형의학회지

Both cervical vestibular evoked myogenic potential (cVEMP) and ocular VEMP (oVEMP) are irreplaceable tools in the current vestibular science, but they have many drawbacks. For example, the test-retest reliability of the asymmetry ratio is inadequate for both tests. The American Academy of Neurology noted that there is insufficient evidence to determine whether cVEMP and oVEMP can accurately identify vestibular function specifically related to the saccule/utricle. One of the most important factors underlying the variability of cVEMP seems to be the control of, and compensation for, baseline muscle contraction power. Reasons for variability in oVEMP include a poor signal to noise ratio, the angle of superior gaze, effective and controlled presentation of stimuli, intracranial pressure, and electrode location. Many of these shortcomings could be improved by further development of recording methods and devices. This article examines the reasons for the insufficient reliability of VEMP and proposes avenues for improvement of VEMP recording systems.

Should the High Septal Deviation be Corrected to Improve Nasal Obstruction During Septal Surgery?

BACKGROUND AND OBJECTIVES: High dorsal deflection of the nasal septum around cartilage or the perpendicular plate is technically difficult to correct. The objective of this study was to assess whether correction of high septal deviation during septoplasty is necessary to improve nasal airflow. PATIENTS AND SURGICAL METHOD: Twenty-one patients with high septal deviation around the septal cartilage or the perpendicular plate were included in this study. In order to improve nasal obstruction, septoturbinoplasty was performed, but high septal deviation was not corrected. Subjective and objective improvements were evaluated using the visual analogue scale and acoustic rhinometry 1 month before and 3 months after surgery. RESULTS: After correction of nasal septum deviation except high septal deviation and reduction of turbinate mucosal volume, postoperative nasal volume and minimum cross-sectional area were significantly increased. Subjective symptom scales for nasal obstruction, rhinorrhea, sneezing, and posterior nasal drip were considerably improved after limited septoturbinoplasty in patients who still had high dorsal deflection of the nasal septum. CONCLUSION: Our findings suggest that limited septoturbinoplasty without excessive resection of high dorsal deflection of the nasal septum can improve nasal airflow and reduce subjective symptoms, including nasal obstruction.

Hirayama Disease with Proximal Involvement

Hirayama disease is a slowly progressing benign motor neuron disease that affects the distal upper limb. A 29-year-old man visited the hospital with a 1-year history of weakened left proximal upper limb. He was diagnosed with Hirayama disease 9 years ago, while there was no further progression of the muscle weakness afterward. Atrophy and weakness was detected in proximal upper limb muscles. Magnetic resonance imaging and somatosensory evoked potentials were normal. Needle electromyography showed abnormal findings in proximal upper limb muscles. Our patient had Hirayama disease involving the proximal portion through secondary progression. Clinical manifestation and accurate electromyography may be useful for diagnosis. Rare cases with progression patterns as described here are helpful and have clinical meaning for clinicians.

The Relationship Between Sleep Disturbance and Functional Status in Mild Stroke Patients

OBJECTIVE: To investigate the sleep state of mild stroke patients and relationship between sleep disturbance and functional status. METHODS: A total of 80 acute stroke patients were enrolled in this study. The criteria for inclusion in the study was as following: 1) first stroke, 2) cognitive function preserved enough to perform the test (Mini Mental State Examination > or =24), 3) good functional levels (Modified Rankin Scale or =3), and 5) less than 2 weeks between the stroke and the assessment. Quality of sleep was assessed by using Pittsburg Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), and Stanford Sleepiness Scale (SSS). Activities of daily living was assessed by using the Modified Barthel Index (MBI) and depressed mood was assessed by using the Beck Depression Inventory (BDI). Gross and fine motor function of the upper extremity was assessed by using hand strength test (Jamar dynamometer), Purdue pegboard test, and the 9-hole peg test. RESULTS: The results of the occupational assessment were fine in the good sleepers. The PSQI, ESS, and ISI were correlated with some of the assessment tools (BDI, MBI, Purdue pegboard, 9-hole peg, and hand strength). CONCLUSION: In conclusion, this study emphasizes that sleep disturbance can affect the functional status in mild acute stroke patients. Therefore, clinicians must consider sleep status in stroke patients and need to work to control it.

Coagulopathies in Transurethral Resection of Prostate Spinal versus General Anesthesia / 대한마취과학회지

BACKGROUND: Unexpected and uncontrolled bleeding remains the principal fear of the surgeon performing transurethral resection of prostate (TURP). Many surgeons and anesthesiologists believe the spinal anesthesia reduces blood loss during TURP. This study evaluate the effects of spinal versus general anesthetic technique on the development of postoperative coagulopathies. METHODS: 20 patients undergoing TURP were randomly allocated into 2 groups. Group I (n=10) received general anesthesia and group II (n=10), spinal anesthesia. PT (prothrombin time), PTT (partial thromboplstin time), Hb (hemoglobin), FDP (fibrin degradation product), platelet and fibrinogen were measured before induction and 24 hours postoperatively. RESULTS: There was no significant difference in measured coagulation variables between the two groups, but there was significant decrease in postoperative Hb compared to preoperative values in both groups and the effect was more pronounced in the general anesthesia than in the spinal anethesia group. CONCLUSION: It is concluded that coagulopathies after TURP is not affected by the anesthetic technique.
