Objective To present a new classification system for reporting results and severity of disease state preoperatively of Eustachian tube (ET) obstructive (ETOD) and non-obstructive dysfunction (ETNOD) based in numerical scores, and to report the results obtained in 40 patients intervened by the author following this criteria. Methods A retrospective review of 25 patients was carried out. 20 patients presented obstructive and 5 patients presented non-obstructive (patulous) Eustachian tube dysfunction. These patients were diagnosed and treated between May 2002 and Dec 2007. Patients with ETNOD received laser endoscopic tuboplasty (LEPT) and in patients with ETOD, a cartilage grafting reconstruction of the antero-lateral wall of the ET (ETR) was carried out endonasally. Results Scores from patients were tabulated accordingly. 18 patients (90%) were symptom free, 1 patient (5%) had partial recurrence of symptoms and 1 patient (5%) had a full recurrence of symptoms at the end of the study in the obstructive dysfunction patients. 3 patients (60%) were symptom free, 2 patients (40%) had partial recurrence of symptoms after Eustachian tube reconstruction. Endoscopy, computed tomography, and audiologic results revealed the efficacy or failure of the interventions. Conclusions 1) This suggested system could serve as a starting point for Eustachian tube surgeons to develop criteria. It could be adopted if eventually accepted in the field. 2) Results obtained indicate that LEPT is effective in relieving symptoms in selected patients. 3) EPTR for patulous disease may be not effective in some cases. New experiences are further needed.

Conditional State

Bronchiectasis is characterized by irreversible widening of the medium-sized airways (ectasia), with inflammation, chronic bacterial infection and destruction of the bronchial walls. This could be due to genetic constitusional state or episodic insidental state which not related to intrinsic imunity. The pathogenesis of bronchiectasis is a combination of repeated inflammation and parenchymal fibrotic, lead to bronchial wall weakening and bronchial irreversibly dilatation.“The vicious cycle” and P aeruginosa contributes on progression and severity of disease. The diagnosis of bronchiectasis is made on the basis of high-resolution computed tomography (HRCT) scan findings. Additional testmay be required in spesific clinical setting. Treatment strategies including antibiotic therapy in acute exacerbation and in controlling the microbial growth, therapy according to intrinsic conditional state, therapy to controll the excessive inflammation, promote bronchial hygiene, and consideration of surgery in some cases. In this review, we will describethe etiologies, pathogenesis, diagnostic investigation, and treatment strategies.

A method of quantifying the symptoms, radiologic data, and endoscopic findings in extensive sinus disease is proposed. It is intended to enable clinicians to classify patients with extensive sinus disease according to severity of disease and prognostic category. The rubric of extensive sinus disease, for scoring and staging, comprises recurrent acute sinusitis and chronic sinusitis, but not an isolated episode of acute sinusitis. The method assigns simple numeric scores to specific computed tomography findings, elements of surgical history, presence of defining symptoms of sinusitis, and endoscopic appearance. This quantitative system may be rationalized into a staging system.

Abstract Background To examine the association between availability of computed tomography (CT) and severity-of-disease/mortality in patients evacuated via long-distance emergency air medical transport from island medical facilities. Methods We retrospectively and consecutively enrolled patients transferred via rotary- or fixed-wing aircraft from island medical facilities to a designated emergency medical center in Tokyo, Japan between 2010 and 2020. Airlifted patients were divided into two groups, depending on the availability of CTs on the island facilities in which they were transported from. The outcomes were severity-of-disease after air medical transport and in-hospital mortality. We examined the association between these outcomes and the availability of CTs on each island facility. Results Eligible patients (n=1,880) were categorized into the CT (n=1,744) or non-CT group (n=136). After adjusting for age, sex, diagnostic category and flight time, the CT group was significantly associated with greater severity of disease (coefficient, 1.30; 95% confidence interval, 0.13–2.47). In contrast, significant reductions in mortality were not documented in the CT group. Conclusion While the availability of CTs was significantly associated with greater severity of disease, CT availability did not significantly impact mortality in patients transferred from island medical facilities.

Three Dimensional Images

We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As conventionally practiced in medical Computed Tomography (CT), radiologists produce maps of bone and tissue structure in several planar sections that reveal features with 1mm resolution and 1% contrast. Microtomography extends the capability of CT in several ways. First, the resolution which approaches one micron, is one thousand times higher than that of the medical CT. Second, our approach acquires and analyses the data in a panoramic imaging format that directly produces three-dimensional maps in a series of contiguous stacked planes. Typical maps available today consist of three hundred planar sections each containing 512x512 pixels. Finally, and perhaps of most import scientifically, microtomography using a synchrotron X-ray source, allows us to generate maps of individual element.
