RESUMO
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. RESULT: In the immunoblotting, the patient's IgE reacted with 18 and 30kDa molecules in the extracts of 6 flours used in the bakery. The patient's PBMC produced a substantial amount of IL-5 and IL-13 in response to these flour extracts. CONCLUSION: It is suggested that water/salt soluble components of wheat flour selectively induce type 2 cytokines production in baker's rhinitis.

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. First, we treated this disease with conservative treatments including a proton pump inhibitor, steroid inhalation, or voice therapy. Surgical treatment was reserved for failures of conservative treatments or when the diagnosis was in doubt. The overall post-surgical recurrence rate was 65.7%, and it was significantly higher in male than female patients, and in younger than older patients. The overall remission rate was 79.7%. A multivariate analysis revealed that Grade II was a significantly poor prognostic factor and the patients with BMI ≥23 or Age <60 had a tendency to have a poor remission rate. The grading system is useful for anticipating the prognosis in cases of vocal process granuloma.

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. Univariate analysis indicated that the period between symptom onset and relief was significantly longer in patients with high levels of C-reactive protein (CRP) (>8.53 mg/dL, p = 0.0073) and without early surgical drainage of pus (p < 0.0001). Multivariate analysis identified both of these values as independently associated with longer duration of symptoms (high CRP, P < 0.0001; no early drainage, P < 0.0001). Univariate analysis indicated that the duration between symptom onset and complete recovery from the disease was significantly longer with age ≥40 years (P = 0.0004), no history of recurrent tonsillitis (P = 0.022), high CRP level (P = 0.0017), and no early surgical drainage of the abscess (P = 0.0014). Multivariate analysis identified older age (P = 0.0004), high CRP level (P = 0.0001), and no early drainage (P < 0.0001) as independently associated with longer duration between symptom onset and complete recovery. Early surgical drainage of the abscess is important for the treatment of peritonsillar abscess. Patients ≥40 years old with peritonsillar abscess and high CRP levels should be recognized as a high-risk group.

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. Tracheotomy and biopsy were performed. Histologically, the lesion showed chronic inflammation with a deposition of fiber-like foreign bodies. The patient had no history of trauma or inhalation injury, but had undergone intratracheal intubation on 4 occasions. The lesion was incised using semiconductor laser photoresection, and the postoperative course was good. To the best of our knowledge, this represents the first report in the English literature of tracheal stenosis caused by unnoticed foreign bodies. The origin of these fiber-like foreign bodies remains unclear but might be related to chronic inflammation resulting from intratracheal intubations.

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. FNA tissues were used to diagnose 14 cases (group A), whereas excisional biopsy was required for accurate diagnosis of 8 cases (group B). These two groups were compared with regard to results of blood examinations, ultrasound appearance, and various other procedures required to reach the final diagnosis. The results indicated that diagnosis of cervical tuberculous lymphadenitis was more difficult for patients with lower white blood cell counts, lower serum C-reactive protein levels, and absence of lymph node fusion or abscess formation on ultrasonography. The possibility of tuberculosis as a cause of cervical lymphadenopathy should always be considered, even when the presenting symptoms are not typical of this disease.

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). METHODS AND RESULTS: Repolarization interval-difference mapping electrocardiograph (187-channel) was performed on 61 patients who received CRT-D. Twenty-one patients experienced appropriate ICD therapy. The interlead difference between corrected recovery time intervals was not significantly different between patients with and without appropriate ICD therapy (98 ± 24 milliseconds versus 88 ± 24 milliseconds). The interlead difference between corrected Tp-e intervals was significantly higher in patients with appropriate ICD therapy than in those without (88 ± 22 milliseconds versus 59 ± 23 milliseconds, P < .001). CONCLUSION: The interlead difference between corrected Tp-e intervals determined by 187-ch RIDM-ECG may be related to appropriate ICD therapy in heart failure patients receiving CRT-D.

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. MATERIALS AND METHODS: The medical records of 40 patients with TTMP who visited the authors' hospital were retrospectively reviewed. RESULTS: Spontaneous closure was observed in 27 (67.5%) patients. The healing period was <2 weeks in 6 cases, <4 weeks in 9, <3 months in 5, <6 months in 3, and ≥6 months in 4. All four cases in which spontaneous closure took ≥6 months exhibited a sign of spontaneous closure at 6 months following injury. Perforation in contact with the malleus was associated with a lower frequency of spontaneous closure. CONCLUSIONS AND SIGNIFICANCE: In TTMP, surgery should be considered in patients who exhibit perforation in contact with the malleus. However, it has also been suggested that long-term observation may be a viable treatment option when a sign of spontaneous closure is observed within 6 months following injury.

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. The duration of recovery was defined as the time from initial diagnosis to complete resolution of local findings and all symptoms. Orbital complications due to postoperative cysts or mycosis were excluded. RESULTS: Twenty-one patients comprised 11 males and 10 females. Chandler's classification showed group I in 4, group II in 8, and group III in 9. None of six pediatric patients required any surgical intervention, whereas five adult patients (23.8%) underwent surgical intervention. The average period of recovery was 8.1 days. In univariate analysis, the duration of recovery was significantly longer among adult cases (p < .01) and cases with Chandler's groups II-III (p = .019). In multivariate analysis, adult patients had a significantly longer duration of recovery than pediatric patients (p = .027). CONCLUSION AND SIGNIFICANCE: The present study suggested that ARS with orbital complications may have prolonged clinical course in adults.

Background: 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. Objectives: 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. Material and methods: We conducted a retrospective analysis of the medical records of 20 TDC patients treated with OK-432 sclerotherapy. Results: Of the 20 patients, OK-432 sclerotherapy was effective in 5 patients (25.0%). OK-432 showed a lower effective rate in multilocular cysts (9.1%) than in unilocular cysts (44.4%), although not significantly. Five cases were treated with surgery following OK-432 sclerotherapy. There was no significant difference in the operating time and the amount of bleeding between patients with and without OK-432 sclerotherapy. From the results of the histological examination of the cyst wall, two cases had stratified squamous epithelium and two cases showed the absence of lymphocyte infiltration. Conclusion and significance: OK-432 sclerotherapy is an acceptable initial treatment for TDC, especially in unilocular cysts, because of lack of influence on surgical procedure.

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). RESULTS: Residual cholesteatoma was found in 11 ears (9.2%). Seven residual cholesteatomas were treated with outpatient operation. Seven ears (5.9%) showed PDRP. A transcanal approach was applied to all PDRPs. Postoperative mastoid reaeration was observed in 57 ears (47.9%). No factors significantly associated with residual cholesteatoma or PDRP were identified. The frequency of postoperative mastoid reaeration was significantly higher among cases with young age (<50 years), stage I cholesteatoma, or type I ossiculoplasty. CONCLUSION: CWDT with SWR showed low rates of residual cholesteatoma or postoperative deep retraction pocket (PDRP). Most residual cholesteatomas and PDRPs could be dealt with using a minimally invasive procedure. Young age, stage I cholesteatoma, and type I ossiculoplasty were associated with postoperative mastoid reaeration. This procedure seems fully feasible for surgical treatment of AC.

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. METHODS: We conducted a retrospective analysis of medical records of 18 patients with AC during the period from 2008 to 2016. RESULTS: None of the 18 patients required an urgent airway intervention. Univariate analysis indicated that the duration of symptoms was significantly longer in patients with cough (p < .01) and younger patients (age < 60, p = .037). The duration of subglottic edema was significantly longer in female (p = .035), patients with high levels of CRP (≥1 mg/dL, p = .049), and patients with cough symptom (p = .035). CONCLUSIONS: Female, young age (<60 years), the symptom of cough, and high levels of CRP should be recognized as signs of prolonged AC. It is important to confirm the diagnosis of AC by laryngoscopic examination, which also help to avoid airway intervention.

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 (8.6%) with glottic cancer first presented to hospitals with complaints other than hoarseness. Although proportions of stage I and T1 disease were significantly higher among patients without hoarseness than among those with hoarseness (p = .0036 and p = .0004, respectively), survival curves showed no significant differences between groups (p = .1334). CONCLUSION: Patients with glottic cancer without complaints of hoarseness were diagnosed at an earlier stage than those with hoarseness. Accumulation of more cases may lead to better survival of patients with glottic cancer without hoarseness compared to those with hoarseness. Checking the larynx of patients without hoarseness or encouraging internists to check the larynx when performing gastroscopic or respiratory examinations may lead to improvement of glottic cancer prognosis. © 2015 Wiley Periodicals, Inc.

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. RESULTS: In 62 of the 100 patients, 71 pathogenic bacteria were identified; 61 (86%) were Gram-positive cocci (GPC), 8 (11%) were Gram-negative rods (GNR), and 6 (8%) were anaerobes. Normal flora were isolated in 27 patients, and culture results were negative in 11 patients. Although not significant, primary (without prior antibiotic therapy) case (odds ratio (OR)=2.19; 95% CI, 0.95-5.05) and laryngeal edema (OR=2.04; 95% CI, 0.82-5.03) showed a tendency of associations with detection of pathogenic bacteria. After taking into account interactions between smoking habit and laryngeal edema, the covariate-adjusted OR for non-smokers with laryngeal edema was significant and showed a strong relationship (OR=7.43; 95% confidence interval, 1.05-52.73) compared to non-smokers without laryngeal edema. CONCLUSION: Although empirical antibiotic therapy was effective for most of the PTA patients, bacteriologic studies might be indispensable for the patients with laryngeal edema considering the failure of the first treatments. Particularly, the culture tests may be useful for non-smokers with laryngeal edema.

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 (18.5%) showed normal laboratory findings. Among these 5 cases, the mean interval between symptom onset and thyrotropin (TSH) suppression was 6.3 weeks, and the mean interval to elevation of fT4 was 6.7 weeks. The longest interval from symptom onset to appearance of an abnormal laboratory finding was 11 weeks. CONCLUSION: Sometimes time-lag exists between onset of clinical symptoms and the appearance of abnormal laboratory findings in patients with SAT. The possibility of this disease should not be excluded from the differential diagnoses for patients with clinical symptoms consistent with SAT but showing normal laboratory findings.

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)). The wave pattern of the 187-ch SAVP-ECG in the representative cases was similar to those in 64-ch MCG. Spatial distribution increased RTc and corrected Tp-e dispersion maps defined by 187-ch SAVP-ECG were in agreement with those by 64-ch MCG. The value of RTc dispersion in MI was higher than that in control (41 +/- 21 ms in MI versus 30 +/- 12 ms in control, P < 0.05). The value of corrected Tp-e dispersion in DCM was higher than that in control (58 +/- 12 ms in DCM versus 30 +/- 13 ms in control, P < 0.001). There was a good correlation between RTc and corrected Tp-e dispersion values determined by 187-ch SAVP-ECG and 64-ch MCG modalities (y = 0.46x + 18, r = 0.62, P = 0.02 for RTc dispersion; y = 0.52x + 15, r = 0.63, P = 0.01 for corrected Tp-e dispersion). RTc and corrected Tp-e dispersion maps by 187-ch SAVP-ECG based on vector-projection theory can evaluate the spatial distribution of myocardial repolarization heterogeneity.
