A multi-centered epidemiological study evaluating the reliability of the treatment difficulty indices developed by the Japan Prosthodontic Society

BackgroundThe diagnostic assessment of the level of difficulty in treating patients who need prosthodontic care is useful to establish a medico-economically efficient system with primary care dentists and prosthodontic specialists.Materials and methodsA multi-axis assessment protocol was established using the newly established treatment difficulty indices. The protocol contains Axis I: oral physiological conditions (e.g., teeth damage and/or missing teeth); Axis II: general health and sociological conditions (e.g., medical disorders); Axis III: oral health-related quality of life (OHRQOL; e.g., oral health impact profile: OHIP); and Axis IV: psychological health (e.g., mood, anxiety, somatoform disorders). A preliminary study on the test–retest consistency of the protocol was conducted to check the levels of reliability of the indices prior to a large-scale, multi-center cohort study on the validity of the protocol.ResultsThe test–retest consistency in terms of the oral physiological condition (Axis I) after data reduction was 0.63 for patients with teeth problems, 0.95 for partially edentulous patients, and 0.62 for edentulous patients. The reliability for general health and sociological conditions (Axis II), OHRQOL (Axis III), and psychological health (Axis IV) were 0.88, 0.74, and 0.61, respectively. These values reflect either “sufficient agreement” or “excellent agreement” in accordance with the criteria established by Landis and Koch (1977) [1].ConclusionThis protocol is the first multi-axis assessment scheme introduced for prosthodontic treatment with sufficient reliability. This new system is therefore expected to have a significant impact on future dental diagnostic nomenclature systems.     

Ultrasound evaluation of fetal brain dysfunction based on behavioral patterns

To identify fetuses at high risk of poor neurological outcomes using a novel ultrasound evaluation system. We assessed an ultrasound evaluation system based on our previous findings, consisting of screening for decreased or lack of fetal movements, abnormal patterns of fetal heart rate, congenital CNS malformations, polyhydramnios of unknown cause, and a “brief ultrasound evaluation” of fetal brain functions, including movement of extremities, breathing movements, ultradian rhythm, REM period, and NREM period. We then assessed the correlation between fetal brain functions and neurological outcomes in infancy (MR, CP, and low Developmental Quotient). During screening, we prospectively evaluated 4978 fetuses receiving prenatal and intrapartum management between January 2000 and December 2009 in our hospital that were later delivered between 32 and 41 weeks’ gestation and identified 93 cases as suspicious for impairment. Of the 93 fetuses, 26 underwent the second step of brief ultrasound examination at 35–40 weeks’ gestation. Our findings revealed that this method was adequately sensitive (80%) and specific (88%) in identifying neurological impairment. We concluded that this method was mainly useful in the clinical setting for establishing the first indication for fetal CNS examination for functional impairment, rendering it suitable for clinical application.     

Tympanic temperature measurements: are they reliable in the critically ill? A clinical study of measures of agreement

OBJECTIVE: Accurate measurement of temperature is vital in the intensive care setting. A prospective trial was performed to compare the accuracy of tympanic, urinary, and axillary temperatures with that of pulmonary artery (PA) core temperature measurements. DESIGN: A total of 110 patients were enrolled in a prospective observational cohort study. SETTING: Multidisciplinary intensive care unit of a university teaching hospital. PATIENTS: The cohort was (mean +/- sd) 65 +/- 16 yrs of age, Acute Physiology and Chronic Health Evaluation (APACHE) II score was 25 +/- 9, 58% of the patients were men, and 76% were mechanically ventilated. The accuracy of tympanic (averaged over both ears), axillary (averaged over both sides), and urinary temperatures was referenced (as mean difference, Delta degrees centigrade) to PA temperatures as standard in 6,703 recordings. Lin concordance correlation (pc) and Bland-Altman 95% limits of agreement (degrees centigrade) described the relationship between paired measurements. Regression analysis (linear mixed model) assessed covariate confounding with respect to temperature modes and reliability formulated as an intraclass correlation coefficient. MEASUREMENTS AND MAIN RESULTS: Concordance of PA temperatures with tympanic, urinary, and axillary was 0.77, 0.92, and 0.83, respectively. Compared with PA temperatures, Delta (limits of agreement) were 0.36 degrees C (-0.56 degrees C, 1.28 degrees C), -0.05 degrees C (-0.69 degrees C, 0.59 degrees C), and 0.30 degrees C (-0.42 degrees C, 1.01 degrees C) for tympanic, urinary, and axillary temperatures, respectively. Temperature measurement mode effect, estimated via regression analysis, was consistent with concordance and Delta (PA vs. urinary, p = .98). Patient age (p = .03), sedation score (p = .0001), and dialysis (p = .0001) had modest negative relations with temperature; quadratic relationships were identified with adrenaline and dobutamine. No interactions with particular temperature modes were identified (p > or = .12 for all comparisons) and no relationship was identified with either mean arterial pressure or APACHE II score (p > or = .64). The average temperature mode intraclass correlation coefficient for test-retest reliability was 0.72. CONCLUSION: Agreement of tympanic with pulmonary temperature was inferior to that of urinary temperature, which, on overall assessment, seemed more likely to reflect PA core temperature.     

Case Report: Shortest Course of Pediatric Paroxysmal Hemicrania

Paroxysmal hemicrania (PH) is a rare primary headache disorder, especially among children. We describe herein a case with the shortest course of pediatric PH among previously reported cases, and the first case report of Japanese pediatric PH. An 11-year-old boy was referred to our clinic by his primary care physician for a headache evaluation. He had been complaining of severe, sharp, pulsating headache for 5 days. Attacks were restricted to the left side with a duration ranging from 2 to 20 minutes, 20-30 times a day. Attacks were associated with left autonomic symptoms (conjunctival injection, lacrimation, nasal congestion, eyelid edema, and ptosis). Two days after we prescribed indomethacin at 0.9 mg/kg/day, the patient was headache free. He stopped taking indomethacin 14 days after consultation because of drug eruptions. As of the time of writing, more than 1 year later, he has experienced no recurrence of headache. This case indicates the importance of improving awareness among general doctors regarding PH in children, and of conducting further investigations about low-dose, short-term indomethacin treatment.
