Holt-Oram Syndrome is an autosomal dominant disorder characterized by the association of upper-limb abnormalities and congenital heart disease. A woman with no family history of genetic disease underwent antenatal sonography at 27 weeks' menstrual age to screen for fetal anomalies. Ultrasonography revealed abnormalities in the upper limbs. The limb abnormalities included abscence of bilateral thumbs and radius: the left humus was short. Pregnancy termination was performed. The postnatal chromosomal analysis revealed a normal 46XX karyotype and the autopsy finding confirmed the Holt-Oram syndrome. We report a case of Holt-Oram Syndrome in fetus with unaffected parents with brief of the literatures.

This study aims to examine the clinical differences between objective short sleep insomniacs (OSSI) and subjective short sleep insomniacs (SSSI). Methods: We enrolled 79 patients (aged 27–74 years) with chronic insomnia disorder (CID) who underwent overnight polysomnography (PSG) and completed sleep-related questionnaires as well as habitual sleep time. All of them completed actigraphy (ACT) recording for one week prior to the PSG study. Objective sleep duration for one-week average sleep was calculated by ACT, and subjective sleep duration was counted through self-reported habitual sleep time. We divided the subjects into three groups; OSSI (<6 hight), SSSI (objective sleep ≥6 hight and subjective sleep <6 h/ night), and normal sleep duration insomniacs (NSDI, subjective sleep ≥6 hight). Results: The three groups namely OSSI, SSSI, and NSDI had 25 (31.6%), 36 (45.6%), and 18 (22.8%) subjects, respectively. The SSSI were significantly older and had higher daytime sleepiness than the OSSI. According to the PSG results, the OSSI showed shorter sleep latency (11.86 min vs. 39.69 min) and N2 sleep % (59.43% vs. 67.96%), and longer rapid eye movement sleep % (20.79% vs. 15.47%) than that in the NSDI. There was no difference in treatment response between groups. Conclusions: 45.6% of CID patients underestimated their sleep relative to objective sleep. However, there were no differences in total sleep time on PSG between groups. The OSSI showed younger age and more daytime sleepiness, and the SSSI showed poorer sleep quality than the NSDI. These findings suggest that long-term ACT recording in a casual environment would be useful to monitor objective sleep in patients with CID, particularly, in subjectively short sleep insomniacs.

Objectives: Sleep issues are more prevalent in healthcare workers compared to workers in other industries. This study investigated sleep-wake pattern, sleep quality, and daytime status in hospital workers using a Galaxy Watch3 (GW3), a wrist-worn device that uses an accelerometer and heart rate sensor to distinguish sleep and wakefulness. Methods: Multiple sleep parameters including total sleep time (TST) were obtained using a GW3. The Epworth sleepiness scale (ESS), insomnia severity index (ISI), Pittsburgh sleep quality index (PSQI), and bedtime procrastination scale (BPS) were used to assess participants’ status. Results: A total of 70 daytime hospital workers (male, 45.7%; mean age, 35.66±7.79 yr) participated in the monitoring of their sleep-wake patterns for 30 consecutive days. Participants had a mean ESS of 8.14±3.62, ISI of 6.13±3.83, and PSQI of 4.86±2.14. The mean TST was 5.75±0.74 hr (range: 3.42–6.88) during workdays and 5.92±0.92 hr (range: 2.87–8.25) during free days. Chronotype (mid-sleep on freedays corrected for sleep debt accumulated over the work week) was 3.60±1.03 clock hr (range: 1.84–6.69). BPS was negatively correlated with age (rho=-0.27, p=0.022), TST of workdays (rho=-0.53, p<0.001), and TST of free days (rho=-0.43, p<0.001). A higher BPS was associated with larger social jetlag (rho=0.28, p=0.018) and later chronotype (rho=0.41, p<0.001). Conclusions In this study, 91.5% of daytime hospital workers suffered from chronic sleep insufficiency (<7 hr during both workdays and free days) although their daytime sleepiness or subjective sleep were not poor. Individuals with a later chronotype had poorer sleep quality and worse sleep procrastination behavior.

Tooth wear, one of the physiological changes in the elderly patient's mouth, generally does not require treatment, but requires prosthodontic restoration when occlusal disharmony, poor masticatory function, pulp exposure occurs. One of the primary considerations in prosthodontic restoration for tooth wear is vertical dimension. It is necessary to make an accurate diagnosis and analysis, correct judgement of the interdental relationship for predictive treatment plan. A step-by-step approach considering dental care for aged is also required. In this case, a 93-year-old male patient presented with worn dentition and mobility of existing fixed dental prosthesis. After diagnosis and evaluation, maxillary rehabilitation without any change in the occlusal vertical dimension was performed and this shows satisfactory results both functionally and morphologically.

PURPOSE: This study was designed 1) to compare the perception of dental professionals and lay people with respect to minor variations in maxillary anterior tooth size and alignment and their relation to the surrounding soft tissues, and 2) to evaluate the normal tooth-gingiva topographical relationships in periodontally healthy young subjects. MATERIALS AND METHODS: Maxillary anterior teeth were intentionally diagrammed in varying degree of deviation with respect to one of three common anterior esthetic discrepancies including variations in crown length, shape of gingival margin, and length of interproximal contact. 17 images were generated to be preferentially selected by 2 groups consisting of dental professionals and lay people (total of 740). Smiling photographs of 120 dental students who had healthy periodontium were taken and the photographic images were analyzed to be classified as 17 kinds of altered image groups. RESULTS: The results demonstrated noticeable difference between the varying levels of discrepancy. Both group preferred gingival margin of lateral incisor to be 0.5mm lower than that of central incisor. Lay people preferred the gingival margin shape that has 2/9 horizontal component of the crown width, while dental professionals preferred the gingival margin shape that has 1/9 horizontal component of the crown width. Lay people preferred longer length of the interproximal contact (two thirds of the crown length), whereas dental professionals preferred shorter length of the interproximal contact (half of the crown length). Photographic analysis of normal esthetic gingival topography revealed 2/9 horizontal component and short length of the interproximal contact which was of the hybrid nature of the preferences shared by lay people and dental professionals. CONCLUSION: The results of this study show that dental professionals and lay people demonstrated significant difference in their preference of dental esthetic components, which may then influence the decision making process by dental professionals with respect to designing the anterior esthetic gingival line.

PURPOSE: Ethanol is the most common toxic substance encountered clinically and is becoming increasingly important in forensic medicine. Generally, pre-treatment with an alcohol disinfectant such as isopropyl alcohol for blood sampling could influence evaluations and affect legal evidence. This study was performed to determine whether isopropyl alcohol affects the serum ethanol level. METHODS: Volunteers were prohibited from drinking alcohol and taking medication for 48 hours prior to participating. Pregnant volunteers and volunteers with abnormal liver enzymes or abnormal kidney function were excluded. Enrolled subjects had their blood collected from each arm to measure the alcohol concentration, one side was disinfected with povidone iodine and the other with isopropyl alcohol. After waiting one hour, they ingested 20g of alcohol and waited. After one hour, the serum ethanol levels were measured using the same method as the first sampling. RESULTS: Ten volunteers enrolled for this study. Without the alcohol intake, all serum ethanol levels were in the nondetectable range(<3 mg/dL) for both samples with either isopropyl alcohol or povidone iodine. After drinking alcohol, the serum ethanol level varied among individuals; the mean value of the serum ethanol levels in the alcohol preparation group was 21.08+/-4.85 mg/dL, which was significantly greater than that of the povidone iodine preparation group (19.71+/-5.47 mg/dL) (p=0.006). However, the Bland-Altman analysis showed that the precision of both groups was 1.230 mg/dL, which was less than the measurement error of the equipment (3.48 mg/dL). Therefore, there was no significant difference between the two groups with regard to the measurement error. CONCLUSION: Before alcohol intake, there was no influence on the blood alcohol concentration from the alcohol disinfection, and the result was reliable. After alcohol intake, the possible influence of pre-treatment alcohol on the serum ethanol level was less than the measurement error of the equipment used.

PURPOSE: This study examined the risk factors of a delayed diagnosis of acute appendicitis in children undergoing an appendectomy. METHODS: This retrospective study involved children aged below 18 years, who underwent an appendectomy. After dividing them into a delayed diagnosis group and nondelayed diagnosis group according to the time interval between the initial hospital visit and final diagnosis, the risk factors of delayed diagnosis were identified using logistic regression analysis. RESULTS: Among 712 patients, 105 patients (14.7%) were classified in the delayed diagnosis group; 92 patients (12.9%) were diagnosed using ultrasonography (US), and both US and computed tomography were performed in 38 patients (5.3%). More patients in the delayed diagnosis group underwent US (P=0.03). Spring season and prior local clinic visit were significantly associated with a delayed diagnosis. Fever and diarrhea were more common in the delayed diagnosis group (fever: odds ratio [OR], 1.37; 95% confidence interval [CI], 1.05–1.81; diarrhea: OR, 1.94; 95% CI, 1.08–3.46; P<0.05). These patients showed symptoms for a longer duration (OR, 2.59; 95% CI, 1.78–3.78; P<0.05), and the admission course (OR, 1.26; 95% CI, 1.11–1.44; P<0.05) and C-reactive protein (CRP) levels (OR, 1.47; 95% CI, 1.19–1.82; P<0.05) were associated with the delayed diagnosis. CONCLUSION: To decrease the rate of delayed diagnoses of acute appendicitis, symptoms such as fever and diarrhea, seasonal variations, admission course, and CRP levels should be considered and children with a longer duration of symptoms should be closely monitored.

PURPOSE: The present study was performed to clarify the relationship between periodontal disease severity and selected immunological parameters consisting of serum IgG titer against periodontopathogenic bacteria, the expression of the helper T-cell cytokine by gingival mononuclear cells, and patients' immunoreactivity to cross-reactive heat shock protein (HSP) epitope peptide from P. gingivalis HSP60. METHODS: Twenty-five patients with moderate periodontitis had their gingival connective tissue harvested of gingival mononuclear cells during an open flap debridement procedure and peripheral blood was drawn by venipuncture to collect serum. The mean level of interproximal alveolar bone was calculated to be used as an index for periodontal disease severity for a given patient. Each of selected immunologic parameters was subject to statistical management to seek their correlations with the severity of periodontal disease. RESULTS: A significant correlation could not be identified between serum IgG titers against specific bacteria (Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum, Actinobacillus actinomycetemcomitans, and Streptococcus mutans) and the severity of periodontal disease. Expression of interleukin (IL)-10 by gingival mononuclear cells was statistically significant in the group of patients who had higher levels of alveolar bone height. However, a similar correlation could not be demonstrated in cases for IL-4 or interferon-gamma. Patients' serum reactivity to cross-reactive epitope peptide showed a significant correlation with the amount of alveolar bone. CONCLUSIONS: It was concluded that expression of IL-10 by gingival mononuclear cells and patients' sero-reactivity to the cross-reactive HSP peptide of P. gingivalis HSP60 were significantly correlated with alveolar bone height.

PURPOSE: This study aimed to discover a way to increase the bond strength between bis-acryl resins, using a comparison of the shear bond strengths attained from bis-acryl resins treated with light curing, pressure, oxygen inhibition, and heat. MATERIALS AND METHODS: Self-cured bis-acryl resin was used as both a base material and as a repair material. Seventy specimens were distributed into seven groups according to treatment methods: pressure - stored in a pressure cooker at 0.2 Mpa; oxygen inhibition- applied an oxygen inhibitor around the repaired material,; heat treatment - performed heat treatment in a dry oven at 60degrees C, 100degrees C, or 140degrees C. The shear bond strength was measured with a universal testing machine, and the shear bond strength (MPa) was calculated from the peak load of failure. A comparison of the bond strength between the repaired specimens was conducted using one-way ANOVA and Tukey multiple comparison tests (alpha=.05). RESULTS: There were no statistically significant differences in the shear bond strength between the control group and the light curing, pressure, and oxygen inhibition groups. However, the heat treatment groups showed statistically higher bond strengths than the groups treated without heat, and the groups treated at a higher temperature resulted in higher bond strengths. Statistically significant differences were seen between groups after different degrees of heat treatment, except in groups heated at 100degrees C and 140degrees C. CONCLUSION: Strong bonding can be achieved between a bis-acryl base and bis-acryl repair material after heat treatment.

BACKGROUND AND OBJECTIVES: Diagnosis of Kawasaki disease (KD) is based on 5 clinical features. Incomplete KD (IKD), which has fewer features, is more common in infants and older children, in whom the rate of coronary artery aneurysms is paradoxically higher. We conducted this study to evaluate risk factors associated with age-at-diagnosis on coronary arterial lesions (CAL) in patients with IKD. SUBJECTS AND METHODS: Retrospective data from 396 patients with KD in a single center were collected from January 2003 to July 2007. Patients were grouped according to their age at diagnosis; Group A (<1 year of age), Group B (1< or =age<5 years of age), and Group C (> or =5 years of age). RESULTS: Among a total of 396 patients with KD, 87 (22.0%) were in Group A, 246 (62.1%) in Group B, and 63 (15.9%) in Group C. In groups A and C, lag times for starting intravenous immunoglobulin (IVIG) were longer than in Group B. There were no differences in the incidence of IKD, late CAL, or rates of IVIG retreatment among the three groups. Among 174 patients with IKD, there were no age-related differences in late CAL incidence or IVIG retreatment. Compared with typical KD, duration of fever and lag times to start IVIG were longer, and the rate of IVIG retreatment was higher in IKD, but there was no difference in the risk of CAL between typical KD and IKD. CONCLUSION: In the management of KD, especially the incomplete type, age-associated factors appear not to be significant for predicting the development of CAL.
