The efficacy of OK-432 sclerotherapy on thyroglossal duct cyst and the influence on a subsequent surgical procedure.

Although there are studies regarding the efficacy of OK-432 sclerotherapy on thyroglossal duct cyst (TDC), its effects on surgical procedure following this therapy have not been properly described. The present study aimed to delineate the prognostic factors of OK-432 sclerotherapy in patients with TDC and investigate its influence on subsequent surgical procedure and the histological characteristics in patients with poor response to OK-432 sclerotherapy. We conducted a retrospective analysis of the medical records of 20 TDC patients treated with OK-432 sclerotherapy.

Spontaneous closure of traumatic tympanic membrane perforation following long-term observation.

Background: Traumatic tympanic membrane perforation (TTMP) is usually managed conservatively because most close spontaneously within a few months. Nevertheless, spontaneous closure of TTMP during long-term observation has not been well described in the literature.

Objectives: The present study investigated factors associated with spontaneous closure of TTMP, and the characteristics of cases exhibiting spontaneous closure following long-term observation.

[THE EXAMINATION OF IGE AND PERIPHERAL BLOOD MONONUCLEAR CELLS RESPONSES TO FLOUR EXTRACTS IN A BAKER'S RHINITIS PATIENT].

Background: Baker's rhinitis is a kind of occupational allergic rhinitis mainly caused by intranasal exposure to wheat and/or rye flour in bakery workers. Continuous exposure to flour may induce the onset of asthma in these patients.

Method: We experienced a case of 34-year-old male with baker's rhinitis without asthma, and investigated responses of IgE and peripheral blood mononuclear cells (PBMCs) to flour extracts used in the bakery in practice.

Factors that prolong the duration of recovery in acute rhinosinusitis with orbital complications.

Background: Regarding prognostic factors of acute rhinosinusitis (ARS) with orbital complications, there are few studies including adult cases.

Objectives: The present study aims to delineate prognostic factors of ARS with orbital complications.

Material And Methods: We conducted a retrospective analysis of medical records of 21 patients (6 pediatric and 15 adult patients) with ARS with orbital complications.

Canal wall-down procedure with soft posterior meatal wall reconstruction in acquired cholesteatoma: focus on postoperative middle ear status.

Objectives: We reviewed surgical results of canal wall-down tympanoplasty (CWDT) with soft posterior meatal wall reconstruction (SWR) for acquired cholesteatoma (AC), and identified factors associated with surgical outcomes.

Methods: Results from 119 ears with AC (pars flaccida, n = 99; pars tensa, n = 20) that underwent CWDT with SWR were retrospectively reviewed. We defined postoperative balloon-like retraction (PBR) with web formation, which needed reoperation to clean accumulated cerumen, as postoperative deep retraction pocket (PDRP).

Prognostic factors and importance of recognition of adult croup.

Objectives: Croup, or laryngotracheobronchitis, is a common disease in childhood. On the other hand, to our knowledge, there are only 14 cases in six English literatures describing adult croup (AC). The clinical features of AC have not been well known.

[A Clinical Study on 64 Cases of Laryngeal Granuloma].

Vocal process granulomas are mainly associated with vocal abuse, gastroesophageal reflux disease (GERD), or endotracheal intubation. In the present study, we evaluate the prognostic factors and the usefulness of a grading system in 64 patients with vocal process granulomas. We classified the granuloma which limited the vocal process of the arytenoid cartilage as grade I, and which originated from the vocal process but extended beyond the vocal process of the arytenoid cartilage as grade II, according to the grading system proposed by Wang CP, et al.

The role of bacteriological studies in the management of peritonsillar abscess.

Objective: Since most patients with peritonsillar abscess (PTA) can be successfully treated with surgical drainage and empirical antibiotic therapy, routine bacteriologic studies for all patients with PTA may be unnecessary. This study tried to evaluate which patients with PTA should certainly undergo bacteriologic studies.

Methods: Hundred consecutive patients with PTA were treated and underwent culture tests of purulent contents obtained by surgical drainage between April 2008 and December 2013.

Glottic cancer in patients without complaints of hoarseness.

Background: Few studies have investigated the clinical characteristics of patients with glottic cancer without hoarseness.

Methods: This retrospective clinical study investigated 371 patients with glottic cancer.

Results: Thirty-two of the 371 patients (8.

Prognostic factors and effects of early surgical drainage in patients with peritonsillar abscess.

Peritonsillar abscess is a frequently encountered otorhinolaryngological emergency, but the characteristics of patients with this disease have not been described in detail. The objective of this study was to delineate prognostic factors associated with peritonsillar abscess and the effects of early surgical drainage for the treatment of peritonsillar abscess. We conducted a retrospective analysis of the medical records of 240 consecutive patients with PTA during the period from 2007 to 2013.

Tracheal stenosis caused by unnoticed foreign bodies.

We describe an extremely rare case of tracheal stenosis caused by unnoticed microscopic fiber-like foreign bodies. A 66-year-old woman complained of dyspnea with inspiratory stridor. Magnifying electroendoscopy and computed tomography revealed stenosis involving the entire circumference of the tracheal lumen.

Time-lag between symptom onset and laboratory findings in patients with subacute thyroiditis.

Objective: The objective of this study was to delineate the frequency of delayed diagnosis in cases of subacute thyroiditis (SAT) and intervals between onset of clinical symptoms and appearance of abnormal laboratory findings.

Methods: We reviewed the medical records of 27 patients (7 men and 20 women) with SAT who visited our hospital between 2007 and 2013.

Results: On presentation to the hospital, 5 of 27 SAT cases (18.

Factors that make it difficult to diagnose cervical tuberculous lymphadenitis.

Cervical tuberculous lymphadenitis is mainly diagnosed by analyzing tissue samples obtained by fine-needle aspiration (FNA). However, some cases remain diagnostic challenges even after polymerase chain reaction analysis of FNA specimens. To delineate differences between cases that are relatively easy to diagnose and those for which diagnosis is difficult, 22 patients with cervical tuberculous lymphadenitis were studied retrospectively.

Interlead difference between T-peak to T-end intervals in resynchronization patients with an implantable cardioverter-defibrillator.

Background: The effectiveness of cardiac resynchronization therapy (CRT) in preventing sudden cardiac death is controversial. Epicardial left ventricular pacing reverses the direction of activation of the left ventricular wall from the epicardium to the endocardium. We evaluated whether the interlead difference between T-peak to T-end (Tp-e) intervals determined by a 187-channel repolarization interval-difference mapping electrocardiograph (187-ch RIDM-ECG) is related to the occurrence of ventricular tachyarrhythmia requiring implantable cardioverter-defibrillator (ICD) therapy in heart failure patients receiving CRT with a defibrillator (CRT-D).

Newly developed signal-averaged vector-projected 187-channel electrocardiogram can evaluate the spatial distribution of repolarization heterogeneity.

The purpose of this study was to verify the spatial distribution of myocardial repolarization heterogeneity using a newly developed 187-channel signal-averaged vector-projected ECG (187-ch SAVP-ECG). We constructed corrected recovery time (RTc) and Tpeak-end (corrected Tp-e) dispersion maps using a 187-ch SAVP-ECG based on vector-projection theory using a Mason-Likar lead system. We compared the spatial distribution and quantitative values of dispersion maps by 187-ch SAVP-ECG with those by 64-ch magnetocardiography (MCG) in 27 normal controls (control) and 16 patients (12 myocardial infarction (MI), and 4 dilated cardiomyopathy (DCM)).
