JOURNAL FREE ACCESSMaxillary sinus symptoms, pathological nasal cavity findings, and ultrasonography results in 249 cases of pediatric sinusitis were studied from initial diagnosis to treatment end. Most (93.4%) showed positive ultrasonography findings concomitant with symptoms and/or pathological nasal cavity findings, confirming ultrasonography reliability in sinusitis diagnosis. Ultrasonography findings proved negative once nasal cavity symptoms and pathological findings disappeared after treatment. Positive ultrasonography findings persisted in subjects (40.7%) having a high recurrence risk compared to those without (3.9%). Imaging is thus useful in confirming correct sinusitis diagnosis.View full abstractDownload PDF (990K) -

JOURNAL FREE ACCESSJapanese cypress pollen dispersal in the spring in Tokushima Prefecture measured in the 26 years from 1981 to 2007 averaged 560/cm2 annually-one third of that of cedar pollen at 1,760/cm2. Cypress pollen amounts varied annually but correlated positively with that of cedar pollen and with weather in the previous summer, although as not strongly as that between cedar pollen amounts and weather in the previous summer. Cypress pollen circulated the most from late March to late April, a month later than cedar pollen. Because cypress and cedar pollen have a common antigen, cypress pollen a month later prolongs and exacerbates spring pollinosis symptoms.View full abstractDownload PDF (407K) -

JOURNAL FREE ACCESSJapanese cedar pollinosis (JCP), an unfortunately common chronic breathing problem, interferes with cognitive function, impairing work productivity and inducing economic loss. We evaluated JCP impact on work productivity, QOL, and symptoms.
Our study, conducted during Japan's peak pollen season, used questionnaires on work productivity and activity impairment allergy-specific (WPAI-AS) and Japanese rhino conjunctivitis QOL (JRQLQ).
The pollen count in 2009-4067.5/cm2 was 3 times that in 2008-1468.4/cm2. Subjects numbered 227 (202 employees and 25 students) in 2008 and 308 (277 employees and 31 students) in 2009. Mean workplace absence was 0.9% in 2008 and 1.2% in 2009 and mean work efficiency loss 33% in 2008 and 42% in 2009. Mean classroom absence was 0% in 2008 and 1.5% in 2009 and mean study efficiency loss 33% in 2008 and 48% in 2009, showing a positive correlation between work productivity score, QOL, and symptoms. Work productivity decreased more in 2009 with increased pollen count.
With the large economic loss due to pollinosis, both symptom severity and QOL must be improved to increase work productivity.View full abstractDownload PDF (562K) -

JOURNAL FREE ACCESSWe report a case of uncommon congenital neonatal choanal atresia (CA) that became apparent postnatally with acute respiratory distress and cyanosis. Simple puncture and stenting for 1 month done 1 week after birth was followed at 10 weeks by transnasal endoscopic repair removing the posterior bony septum and widening the choana. This technique has proven quite useful in treating neonatal CA.View full abstractDownload PDF (620K) -

JOURNAL FREE ACCESSWe report clinical outcomes in 47 cases of surgically resected inverted maxillary sinus papilloma between 1998 and 2007.
Surgery involved (1) broadening the endoscopic surgical field by partially dissecting the tumor in marked bleeding or microdebriding the tumor; (2) identifying tumor origin; and (3) excision.
Endoscopic sinus surgery (ESS) was done in 29 cases and endoscopic transmaxillary surgery (ETMS) in 18. Recurrence occurred in 4 cases due, we beliere to insufficient intraoperative origin identification and excision. Neither piecemeal resection nor microdebrided tumor reduction disseminated tumor cells or relapse.
Our results thus clearly indicate that surgery should focus on the identification and excision of the tumor origin rather than on tumor bulk resection as is conventionally done.View full abstractDownload PDF (1150K) -

JOURNAL FREE ACCESSAlthough non-surgical control of epistaxis by nasal packing is effective in many cases, the otolaryngologist may see some case of posterior epistaxis that become intractable and require repeated nasal packing. Between 2006 april and 2010 march, 12 patients with intractable posterior epistaxis -8 men and 4 women-were treated by endoscopic sphenopalatine artery coagulation with a harmonic scalpel at Yamagata university hospital and Yamagata Prefectural Central Hospital. Only one patient had subsequent epistaxis from Kiesselbach's plexus, 7 months postoperatively. Only one patient had a postoperative complication (acute sinusitis). Endoscopic coagulation may thus be appropriate for treating severe recurrent epistaxis refractory to repeated nasal packing.View full abstractDownload PDF (700K) -

JOURNAL FREE ACCESSPurpose: Inferior turbinates chemosurgery with trichloroacetic acid (TCA) has been assessed histopathologically in allergic rhinitis by comparing bilateral inferior turbinates with both sides treated by turbinectomy and only the deviation-free side treated with TCA due to a deviated nasal septum.
Because such deviation may influence comparison results, we assessed its influence on Th2 and Th1 cell infiltration of specimens. Subjects: Specimens were bilateral inferior turbinate membranes from 13 subjects with non treated HD allergy. Methods: The two types of cells were counted immunohistochemically per 1mm2 per specimen. Two-way analysis of variance used the deviation and cell type as primary factors. Results: The cell type, but not the deviation factor, was significant at p<0.01. Conclusion: The deviation factor was not related to Th2 or Th1 cell infiltration, but has not been accounted for conventional assessment. Our results confirmed that necessity of the deviation factor need not be considered in assessing TCA treatment efficacy.View full abstractDownload PDF (521K) -

JOURNAL FREE ACCESSDespite the growing population demonstrating Japanese cedar pollinosis in Japan, a standard prophylactic dose remains to be established. We evaluated the clinical prophylactic efficacy of half a dose of olopatadine hydrochloride.
Subjects were divided into 2 groups: patients who had taken half a dose of olopatadine hydrochloride before the beginning of pollen season versus patients received intra-season administration of olopatadine hydrochloride without prophylactic treatment. We used symptom diaries and the Japan rhino conjunctivitis quality of life questionnaire (JRQLQ) to determine subjective symptoms, objective nasal findings, and QOL scores.
Nasal congestion showed significant improvement from the early period of pollen scattering in the prophylactic treatment group and there was also a significant improvement of sneezing during the middle of the pollen season. Furthermore, itching of the eyes as well as watery eyes showed significant improvement from the early period of scattering. The prophylactic treatment group showed inhibition of symptoms after scattering started for each item on JRQLQ compared with that in the intra-season administration group. The quality of life for these patients also tended to be improved.
These findings suggest that half a dose of olopatadine hydrochloride is useful as an improved prophylaxis regimen.View full abstractDownload PDF (554K)
