Pericardial defect is a rare congenital cardiac disorder. Most patients were asymptomatic but some patients with partial pericardial defect occasionally complain acute symptoms such as angina, syncope, rarely sudden cardiac death. So, differential diagnosis with other ischemic or structural heart disease is crucial in the management of such patients. But there is no consistently successful diagnostic method. In the past, artificial diagnostic pneumothorax was used to document the absence of pericardium. However, it is not easily accepted due to excess morbidity and failure rate. Recently, echocardiography and more often, computed tomography, magnetic resonance imaging are used to confirm the diagnosis. We experienced a 52 years old male patient with atypical chest pain, who was diagnosed as complete left pericardial defect with computed tomography.

Situs inversus totalis with dextrocardia is a rare congenital anomaly and its incidence is approximately 1: 6,000-35,000 in general population. Such patients usually have structurally normal hearts and are expected to have normal life span. Coronary angioplasty in such patients have previously been reported, but reported cases in literature are scanty. This report describes our experience of successful percutaneous transluminal coronary angioplasty with stent in acute myocardial infarction patient with situs inversus totalis and dextrocardia who exhibited total occlusion of the mid left anterior descending coronary artery.

Objective:
To identify the variables of videofluoroscopic swallowing study (VFSS) that are useful for predicting the risk of aspiration pneumonia in elderly patients with dysphagia.
Methods:
A total of 251 patients (aged 65 years or more) were included and divided into a pneumonia group (n=133) and a non-pneumonia group (n=118). The pneumonia group included patients who had been diagnosed with aspiration pneumonia, and individuals in the non-pneumonia group did not have pneumonia but were referred for VFSS. The medical records and results of VFSS were reviewed and compared between the groups retrospectively.
Results:
The pneumonia group exhibited a male preponderance and a higher 8-point Penetration-Aspiration Scale (8PPAS) score. The mean values of 8PPAS score for swallowing thick liquid and rice porridge was significantly higher in the pneumonia group. The pharyngeal delay time (PDT) and pharyngeal transit time (PTT) were significantly longer in the pneumonia group. The amounts of vallecular and pyriform sinus residue were increased in the pneumonia group. The delay in swallowing reflex and the decrease in laryngeal elevation were more frequently observed in the pneumonia group. Among those variables, PDT and PTT were identified as significant predictors of aspiration pneumonia based on logistic regression analysis.
Conclusion
The present study delineated the findings of VFSS, suggesting an increased risk of aspiration pneumonia in elderly patients with dysphagia. The results demonstrate that prolonged PDT and PTT are significant predictors of aspiration pneumonia.

OBJECTIVE: To evaluate the bioactivity, and the biomechanical and bone-regenerative properties of Ti6Al4V miniscrews subjected to anodization, cyclic precalcification, and heat treatment (APH treatment) and their potential clinical use. METHODS: The surfaces of Ti6Al4V alloys were modified by APH treatment. Bioactivity was assessed after immersion in simulated body fluid for 3 days. The hydrophilicity and the roughness of APH-treated surfaces were compared with those of untreated (UT) and anodized and heat-treated (AH) samples. For in vivo tests, 32 miniscrews (16 UT and 16 APH) were inserted into 16 Wistar rats, one UT and one APH-treated miniscrew in either tibia. The miniscrews were extracted after 3 and 6 weeks and their osseointegration (n = 8 for each time point and group) was investigated by surface and histological analyses and removal torque measurements. RESULTS: APH treatment formed a dense surface array of nanotubular TiO2 layer covered with a compact apatite-like film. APH-treated samples showed better bioactivity and biocompatibility compared with UT and AH samples. In vivo, APH-treated miniscrews showed higher removal torque and bone-to-implant contact than did UT miniscrews, after both 3 and 6 weeks (p < 0.05). Also, early deposition of densely mineralized bone around APH-treated miniscrews was observed, implying good bonding to the treated surface. CONCLUSIONS: APH treatment enhanced the bioactivity, and the biomechanical and bone regenerative properties of the Ti6Al4V alloy miniscrews. The enhanced initial stability afforded should be valuable in orthodontic applications.

PURPOSE: We compared intra-individual visual outcomes and patient satisfaction after implantable contact lens (ICL) and Toric ICL implantation. METHODS: Twenty-eight eyes of 14 patients were enrolled in this retrospective study. One eye of each patient was assigned to ICL (ICL Group), and the contralateral eye was allocated to Toric ICL (Toric ICL Group). All patients were examined for visual acuity, refraction, intraocular pressure, slit lamp measurements, and satisfaction one week, one month, two months, and six months postoperatively. RESULTS: Mean spherical equivalents of the two groups were corrected from -7.83D (ICL Group) and -5.55D (Toric ICL Group) to 0.13D and 0.20D, respectively, and the mean refractive cylinders were corrected from 0.92D and 2.60D to 0.42D and 0.27D, respectively, at six months postoperatively. The myopias of these two groups and the astigmatism of the Toric ICL group were effectively corrected. The uncorrected visual acuity (UCVA) of the two groups were 1.02 and 1.05, respectively, at six months postoperatively. The safety index, efficacy index, predictability, and stability were favorable. There were no significant differences between the two groups in terms of postoperative UCVA, intraocular pressure(IOP), vaulting, noticeable complications, or patient satisfaction. CONCLUSIONS: The results show ICL implantation is effective treatment for high myopia, and Toric ICL implantation is a viable surgical option for the treatment of compound myopia astigmatism. Selection of proper phakic intraocular lens(IOL) is recommended for correcting astigmatism.

Moyamoya disease is a rare progressive occlusive disease in the internal carotid arteries, along with the presence of an abnormal capillary network of vessels at the base of the brain. In moyamoya disease, the manitaining of cerebral perfusion and cerebral oxygen saturation are required to reduce complications of this disease including cerebral ischemia and cerebral hemorrhage. The authors measured regional oxygen saturation (rSO2) nonivasively by INVOS 5100 (Somanetics, USA) in patients with moyamoya disease who were scheduled for an encephalo-duro-arterio-myo synangiosis (EDAMS) operation. We therefore report our findings that deep breathing decreased rSO2 and oxygen, elevated blood pressure, and that the cerebral vasodilating drug increased rSO2.

Longitudinal bone growth is primarily mediated by the growth plate, which is a specialized cartilaginous structure. Aggrecan, encoded by ACAN, is a primary proteoglycan component of the extracellular matrix in both the growth plate and articular cartilage. Aggrecanopathies have emerged as a phenotype of genetic skeletal disease in humans. A heterozygous ACAN mutation causes short stature, premature growth cessation, and accelerated bone age maturation. We report the case of a 15-year-old boy with familial short stature, with height of 149 cm (Korean standard deviation score [SDS] of -3.6) and weight of 50.5 kg (-1.48 SDS). He presented with mild midfacial hypoplasia, frontal bossing, a broad chest, and a short neck. The father's and mother's heights were 150 cm (-4.8 SDS) and 153 cm (-1.69 SDS), respectively. The patient's bone age was 2–3 years more advanced than his chronological age, and no endocrine abnormalities were detected. Wholeexome sequencing followed by Sanger sequencing revealed a heterozygous ACAN mutation, c.512C>T (p.Ala171Val), in both the proband and his father. Short stature is generally associated with a delayed bone age, and this case suggests that ACAN mutations may be the most likely etiology among patients with short stature and an advanced bone age and should warrant early treatment.

STUDY DESIGN: Radiographic review of healthy volunteers. PURPOSE: To determine the ideal sitting positions by measuring changes in lumbar lordosis (LL) and pelvic parameters (PPs) in various positions. OVERVIEW OF LITERATURE: Prolonged sitting is generally accepted as an important risk factor for low back pain (LBP). It is now recognized that spinopelvic alignment is important for maintaining an energy-efficient posture. METHODS: Lateral spine radiographs of thrirty healthy volunteers (male participants) were taken in standing and five sitting positions. Radiographic measurement of LL and PPs was performed in each position. Statistical analysis was performed to identify a correlation between changes in the LL and PPs in each positions. RESULTS: LL in standing was 48.5degrees+/-8.7degrees. Sitting significantly decreased LL and segmental angle when compared with standing (p<0.05). The lower lumbar segmental angles (L4-5 and L5-S1) significantly decreased in all sitting positions (p<0.05), but the decrease was relatively less on the chair with lumbar support and in the 90degrees-angled chair. The sacral slope (SS) decreased and the pelvic tilt increased with decreasing LL in the sitting positions. CONCLUSIONS: Sitting causes a reduction in LL and SS when compared with standing. It might cause a spinopelvic imbalance and result in chronic LBP. Our study showed that sitting on a chair with back support induced minimal changes to LL. Consequently, it is proposed that sitting on a chair with back support would be a much more ideal position than sitting on other types of chairs.
