Interoceptive hypersensitivity and interoceptive exposure in patients with panic disorder: specificity and effectiveness.
BACKGROUND: Interoceptive exposure has been validated as an effective component of cognitive behavioral therapy (CBT) for the treatment of panic disorder but has hitherto received little research attention. We examined the effectiveness of various interoceptive exposure exercises using the Body Sensations Questionnaire (BSQ) (Chambless et al., 1984). METHODS: We first performed an exploratory principal factor analysis of all the items contained in the BSQ to obtain meaningful dimensions of interoceptive fears. Next, we examined the correlations between each interoceptive exposure task's degree of similarity to panic attacks and each BSQ factor and then examined whether the BSQ factor scores decreased in comparison with the baseline values when the corresponding exposure tasks were successfully completed by the subjects. RESULTS: The factor analyses revealed four factors, which we named "pseudoneurological fears", "gastrointestinal fears", "cardiorespiratory fears" and "fears of dissociative feelings." Among the nine interoceptive exposure tasks, 'hyperventilation', 'shaking head', 'holding breath' and 'chest breathing' were considered to reproduce pseudoneurological symptoms, 'breathing through a straw' was considered to reproduce gastrointestinal symptoms, and 'spinning' was considered to reproduce both pseudoneurological and dissociative symptoms; none of the interoceptive exercises were found to reproduce cardiorespiratory symptoms. Among each group of patients for whom 'hyperventilation', 'holding breath', 'spinning' or 'chest breathing' was effective, a significant improvement in the BSQ pseudoneurological fears factor scores was observed. On the other hand, no significant difference between the baseline and endpoint values of the BSQ gastrointestinal fears or the BSQ fears of dissociative feelings factor scores were observed among the patients for whom 'spinning' or 'breathing through a straw' was effective. CONCLUSION: Several interoceptive exposure tasks were particularly effective in reducing pseudoneurological fears. New interoceptive tasks, especially tasks related to cardiorespiratory and dissociative feelings, are needed.

[A Kumamoto model of clinical training in tracheal intubation for paramedics].
BACKGROUND: Since July 2004, the Japanese Ministry of Health, Labor and Welfare approved certified paramedics to perform emergency prehospital tracheal intubation. A specialized training system in tracheal intubation has been established in Kumamoto Prefecture. METHODS: The Kumamoto Prefectural Medical Control Organization, a tracheal intubation task force was established: consisting of the departments of Anesthesiology at Kumamoto University and 11 other major hospitals, along with Kumamoto Prefecture and the 14 prefectural fire-departments. This group published the Kumamoto training guidelines and a training system for paramedics. RESULTS: Kumamoto Prefecture appealed for support of paramedic activity on television and in newspapers as public education. The prefectural governor officially asked hospitals to train paramedics. Because 9 of the 14 fire-departments had no regional teaching hospital, trainees were matched with other hospitals by the task force. The task force published a pamphlet to inform surgical patients about tracheal intubation training and to recruit patients as practice volunteers. Anesthesiologists undertook significant roles in making arrangements to facilitate the project at their hospitals, in addition to teaching paramedics prior to surgical procedures. CONCLUSIONS: The Medical Control Organization, Kumamoto Prefecture, anesthesiologists and emergency response personnel worked together successfully to promote the training program for clinical tracheal intubation by paramedics.

Prediction of prognosis for acute respiratory distress syndrome with thin-section CT: validation in 44 cases.
PURPOSE: To retrospectively evaluate whether the thin-section computed tomographic (CT) appearance has prognostic value for prediction of mortality, number of ventilator-free days (ie, days without mechanical ventilation), and 28-day risk of barotrauma in patients with a clinically early stage of acute respiratory distress syndrome (ARDS) from diverse causes. MATERIALS AND METHODS: Institutional review board approval and informed consent were obtained. Two independent observers who were blinded to patient outcomes retrospectively evaluated the thin-section CT scans obtained within 7 days after clinical ARDS onset in 26 survivors and 18 nonsurvivors. Of 44 patients, there were 37 men and seven women (mean age +/- standard deviation, 61.8 years +/- 15.6). CT findings were graded on a scale of 1-6 that corresponded with consecutive pathologic phases: score of 1, normal attenuation; score of 2, ground-glass attenuation; score of 3, consolidation; score of 4, ground-glass attenuation associated with traction bronchiolectasis or bronchiectasis; score of 5, consolidation associated with traction bronchiolectasis or bronchiectasis; and score of 6, honeycombing. An overall CT score was obtained by adding the six averaged scores (three zones in each lung). Multivariate regression analysis was used to assess the independent predictive value of the CT score. RESULTS: The area of increased attenuation associated with traction bronchiolectasis or bronchiectasis (P = .002), as well as the overall CT score (P = .002), was smaller in survivors than in nonsurvivors. Results of multivariate regression analysis revealed that CT score was independently associated with mortality (P = .006). A CT score of less than 230 enabled prediction of survival with 73% sensitivity and 75% specificity and was associated with both a greater number of ventilator-free days (P = .018) and a lower incidence of barotrauma (P = .013) within 28 days after ARDS onset. CONCLUSION: Extensive thin-section CT abnormalities indicative of fibroproliferative changes were independently predictive of poor prognosis in patients with a clinically early stage of ARDS.

Gradations of clinical severity and sensitivity to change assessed with the Beck Depression Inventory-II in Japanese patients with depression.
Knowledge of what constitutes a minimal clinically important difference and change on a psychiatric rating scale is essential in interpreting its scores. The present study examines the Beck Depression Inventory-II (BDI-II), a recently revised successor to the world's most popular self-rating instrument for depression. BDI-II was administered to 85 patients with major depression, diagnosed with DSM-IV along with its severity specifiers. It was again administered to 40 first-visit patients from the original sample when they returned 14 or more days later. The Clinical Global Impression-Change Scale was rated at the same time. All the ratings were done independent of each other. The BDI-II was able to distinguish between all grades of depression severity. An approximate 10-point difference existed between each severity specifier. The BDI-II was also sensitive to change in depression: a 5-point difference corresponded to a minimally important clinical difference, 10-19 points to a moderate difference, and 20 or more points to a large difference. Given the already established high reliability, content validity, construct validity and factorial validity, and the high sensitivity to between-subject differences and within-subject changes demonstrated in the present study, the BDI-II promises to continue to be a leading self-rating instrument to assess depression severity worldwide.

[Operative technique aiming at en bloc dissection in esophageal surgery].
The lymph node metastases of esophageal cancer occur over a wide area. It is essential for radical surgery of such metastases to aim at en bloc dissection. Otherwise, it can easily become a combination of blunt esophagectomy and lymph node sampling through a right thoracotomy. In the intrathoracic procedure, all the nodes to be dissected can be harvested while attached to the esophagus together with the surrounding connective tissue, except for the pretracheal nodes in front of the cardiac branches of the right vagus nerve and the subaortic arch nodes. It is important to dissect the left paratracheal nodes en bloc, preserving the left recurrent laryngeal nerve. In the abdomen, nodes around the celiac axis and nodes on the common hepatic artery and proximal part of the splenic artery are all removed en bloc with the perigastric nodes in the left gastric arterial basin. The cervical paratracheal and paraesophageal nodes are removed separately from the resected esophagus, but the continuity of dissection can be ensured when the dissection from the neck meets the empty space made by the dissection along the bilateral recurrent laryngeal nerves through the thoracotomy. We believe that such en bloc dissection is the key to improving the long-term results of esophageal cancer surgery.

[Antispasm therapy using combination of midazolam and propofol for severe tetanus].
A 68-year-old healthy woman without any evidence of recent wound, developed nuchal pain, difficulty in swallowing and trisumus in 10 days. Because of respiratory failure due to generalized muscle spasm, she was intubated and required mechanical ventilation. Midazolam was administered as an antispastic therapy followed by human tetanus immune globulin and tetanus toxoid. Propofol was added on 9 days after intubation, since muscle spasm such as opisthotonus or respiratory spasm did not improve under midazolam and intermittent administration of vecuronium. Thereafter, her muscle spasm and hypertensive response were well controlled. The authors suggested that a combined use of midazolam and propofol was an optional antispastic therapy in patients with severe tetanus.

Possible role of increased oxidant stress in multiple organ failure after systemic inflammatory response syndrome.
OBJECTIVE: Host response to infection and other forms of tissue injury have been termed systemic inflammatory response syndrome (SIRS). This inflammatory response can frequently be accompanied by oxidative injury in one or more organ systems in the body. The objective of this report was to clarify the possible role of oxidative stress in the development of multiple organ failure (MOF) in patients with SIRS. DESIGN: Prospective clinical study. SETTING: Intensive care unit in a university hospital. PATIENTS: A total of 214 consecutive patients (mean age, 57.1 +/- 17.4 yrs; range, 13 to 84 yrs; 148 men and 66 women). At the time of admission, 139 patients fulfilled the clinical criteria for SIRS. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We measured plasma concentrations of thiobarbituric acid reactant substances (TBARS), as an index of oxidative stress, every day from the point of admission to the intensive care unit until discharge or death. Furthermore, all variables of the SIRS score and the Sequential Organ Failure Assessment score were collected every day. At the time of admission, plasma TBARS concentrations in SIRS patients with MOF were significantly higher than those in SIRS patients without MOF (2.3 +/- 0.9 vs. 1.9 +/- 0.6 nmol/mL, p <.01), and there was a significant correlation between plasma TBARS concentration and Sequential Organ Failure Assessment score (r2 =.18, p <.001). Furthermore, the duration of SIRS persistence was significantly associated with the percentage increase in plasma TBARS concentration during SIRS persistence in those patients in whom the duration of SIRS was confirmed (r2 =.73, p <.001). The duration of SIRS was significantly higher in patients who developed MOF than in patients who did not develop MOF (6.9 vs. 3.2 days, p <.001). The percentage increase in plasma TBARS concentration during SIRS was also significantly higher in patients who developed MOF than in patients who did not develop MOF (57.1% vs. 15.8%, p <.001). CONCLUSIONS: It can be concluded that processes of oxidative stress in connection with continued SIRS may promote the development of MOF.
