OBJECTIVES: The aim of this study was to know differences of characteristics between presenile and senile patients who were consulted to the department of psychiatry during medical-surgical admission. METHODS: The demographic and clinical data obtained from the medical records of psychiatric consultation in the presenile inpatients with age 50 to 64 years(N=162) and those of the senile inpatients with age over 65 years(N=171) were reviewed and compared. RESULTS: 1) The most common chief complaints for psychiatric consultation in presenile patients were somatic symptoms, anxiety and sleep disturbance in order, while cognitive decline, clouded consciousness and depressed mood were most common in senile patients with statistical significance. 2) The most frequent psychiatric diagnoses after consultation in presenile patients were delirium, mood disorder and substance use disorder in order, while delirium, mood disorder and major neurocognitive disorder were most frequent in senile patients with statistical significance. 3) There were no significant difference in numbers of physical illnesses, while numbers of therapeutic drugs for them were more in senile patients. CONCLUSIONS: Our study found significant differences between presenile and senile patients on psychiatric symptoms and diagnoses in geropsychiatric consultation. Therefore, more subdivided age-specific approach seems to be needed for the geropsychiatric consultation activities.

OBJECTIVES: The purpose of this study was to evaluate the polymerization shrinkage stress among conventional methacrylate-based composite resins and a silorane-based composite resin. MATERIALS AND METHODS: The strain gauge method was used for the determination of polymerization shrinkage strain. Specimens were divided by 3 groups according to various composite materials. Filtek Z-250 (3M ESPE) and Filtek P-60 (3M ESPE) were used as a conventional methacrylate-based composites and Filtek P-90 (3M ESPE) was used as a silorane-based composites. Measurements were recorded at each 1 second for the total of 800 seconds including the periods of light application. The results of polymerization shrinkage stress were statistically analyzed using One way ANOVA and Tukey test (p = 0.05). RESULTS: The polymerization shrinkage stress of a silorane-based composite resin was lower than those of conventional methacrylate-based composite resins (p < 0.05). The shrinkage stress between methacrylate-based composite resin groups did not show significant difference (p > 0.05). CONCLUSIONS: Within the limitation of this study, silorane-based composites showed lower polymerization shrinkage stress than methacrylate-based composites. We need to investigate more into polymerization shrinkage stress with regard to elastic modulus of silorane-based composites for the precise result.

Extracorporeal shockwave therapy (ESWT) has been reported to be a safe and effective method for decreasing pain and relieving range of motion (ROM) limitations caused by neurogenic heterotopic ossification (NHO), though there has been no report that it might cause hematoma if applied to NHO. We hereby report a case of massive hematoma after ESWT, specifically the radial shockwave therapy (RSWT) device at both hips in a 49-year-old female patient with NHO. She had developed NHO after extensive subarachnoid hemorrhage. We had applied RSWT according to the previous report. The pain and the ROM limitations were gradually improved. Six weeks later, she reported pain and ROM limitations on the right hip. From a medial aspect, swelling and bruising of the right thigh could be seen. Magnetic resonance imaging and ultrasonography suggested a large hematoma between right hip adductor muscles. The symptoms disappeared after conservative treatment for one month, and subsequent follow-up imaging studies demonstrated resolution of the hematoma.

The effects of embryo number and incubation volume on the development of mouse embryos were evaluated. The growth rate of two-cell mouse embryos to attached blastocyst stage and the growth rate of blastocysts to early somite stage were assessed after culture in different incubation volumes and embryo densities. Embryos were collected from ICR female mice superovulated with pregnant mare serum gonadotropin and human chorionic gonadotropin and mated by ICR males. In experiment 1, groups of one, five, ten, twenty 2-cell embryos were cultured in 10-, 50-, 500-, 1000-microliter drops of BWW media under mineral oil at 37 degrees C in a humidified atmosphere of 5% CO2 and 95% air. As the incubation volume decreased, significantly (p<0.05) higher rates of embryos reached morular and blastocyst stage on day 3 and 4 culture, respectively In experiment 2, groups of one, five, ten, twenty blastocysts were cultured in 1- and 2-ml volumes of CMRL 1066 media under same condition as in experiment 1. However the reverse was the result. Decreasing the number of embryos incubated per volume from 1 to 20 significantly (p<0.05) increased the number of blastocysts reaching the late egg cylinde. (LEC) and early somite (ES) stage on day 6 and 8 culture, respectively, regardless of incubation volume. Blastocysts cultured in 2ml had higher (p<0.05) development rates to LEC and ES stage on day 6 and 8 culture, respectively, than embryos cultured in 1ml. Our results suggest that the effects of embryo number and incubation volume on the development of mouse embryos are stage specific and the shifting point was between hatching and EEC stage.

BACKGROUND: The sitting position under general anesthesia is associated with hemodynamic instability. The purpose of this study was to compare the efficacy of a sequential compression device (SCD) with that of elastic stockings (ES) in reducing the incidence of hypotension and other hemodynamic instability in the sitting position during shoulder arthroscopy. METHODS: Fifty-one patients undergoing shoulder arthroscopy were randomly assigned into one of three groups to receive no treatment (control group, n = 17), SCD (SCD group, n = 17) or ES (ES group, n = 17). Hemodynamic variables were measured 5 min after induction of anesthesia (baseline values), and every 1 min from 1 to 5 min after raising the patient to a 70degrees sitting position (T1-5) with the beach-chair. RESULTS: The incidences of hypotension (proportion, 95% CI) were 12/17 (0.71, 0.47-0.87), 5/16 (0.31, 0.14-0.56) and 7/15 (0.47, 0.25-0.70) in the control, SCD and ES group, respectively. The incidence was significantly lower in the SCD group than that in the control group (P = 0.038). At 1 min after sitting position, mean arterial pressure in the control group was significantly lower than that in the SCD group and it was significantly decreased from the baseline value. CONCLUSIONS: SCD could significantly reduce the incidence of hypotension with less hemodynamic instability in the sitting position during shoulder arthroscopy. Although the incidence of hypotension was decreased with the elastic stocking, there was no statistical significance.

PURPOSE: To evaluate the usefulness of locking compression plate (LCP) and volar plating through anterior approach for distal radius fracture. MATERIALS AND METHODS: We retrospectively analysed that 15 distal radius fracture, which would not be reduced by closed reduction or too comminuated to maintain reduction or articular surface inconguency, were treated by open reduction through anterior approach and volar plating using LCP. The results were evaluated by preoperative and postoperative radiographs. Functional results were analysed using the Modified Mayo Wrist Scoring System. RESULTS: All cases achieved anatomical articular surface reduction postoperatively. In terms of radiologic analysis, mean radial length (9.0 mm vs. 11.8 mm), radial inclination (14.7degrees vs. 20.9degrees ), volar tilt (-6.3degrees vs. 8.3degrees ) and articular step-off (1.4 mm vs. 0.3 mm) were improved. The average Modified Wrist Score was 89. Nonunion or malunion was not occurred. CONCLUSION: Open reduction through anterior approach and volar plating using LCP is a useful method that provides excellent results with few complications in the treatment of fracture of the distal radius.

Gitelman syndrome is an autosomal recessive renal tubular disorder characterized by hypokalemic metabolic alkalosis, and it is distinguished from Batter syndrome by hypomagnesemia and hypocalciuria. This disorder is caused by mutation in SLC12A3 gene which encodes thiazide-sensitive Na(+)-Cl(-)cotransporter (NCCT) which is expressed in the apical membrane of cells, lining distal convoluted tubule. A 8-year old boy who presented with Rolandic epilepsy, and horseshoe kidney accidentally showed clinical features of metabolic alkalosis, hypokalemia, hypocalciuria without hypomagnesemia. So we identified a heterozygote mutation and an abnormal splicing in the SLC12A3 gene, encoding NCCT. The mutation was detected in the exon 15 and 22 of SLC12A3 gene.

OBJECTIVE: To evaluate the effects of the videofluoroscopic swallowing study (VFSS) timing after the nasogastric tube (NGT) removal on swallowing function of the patients with dysphagia. METHODS: This study was conducted on 40 NGT-fed patients with dysphagia. To assess the patients' swallowing function, VFSS was performed twice using a 5-mL 35% diluted barium solution. For the initial examination, VFSS was performed immediately after the NGT removal (VFSS 1). For the second examination, VFSS was performed five hours after the NGT removal (VFSS 2). We used the functional dysphagia scale (FDS) to assess swallowing function. In the FDS, a significant difference in the four items in the oral phase, seven items in the pharyngeal phase, and total scores were assessed (p<0.05). We also used modified penetration-aspiration scale (mPAS) to compare the two examinations (p<0.05). RESULTS: A paired t-test was performed to confirm the statistical significance of the two examinations (p<0.05). The overall swallowing function was assessed as better in VFSS 2 than in VFSS 1. In the FDS, significant differences in the residue in valleculae (p=0.002), the residue in pyriform sinuses (p=0.001), the coating of pharyngeal wall after swallow (p=0.001), and the total scores (p<0.001) were found between the two examinations. Also, in the mPAS that assessed the degree of penetration-aspiration, a significant difference was found between the two examinations (p<0.001). CONCLUSION: The results of this study confirmed that the timing of the VFSS after the NGT removal affects the swallowing function. Thus, to accurately assess the swallowing function, VFSS must be performed in NGT-fed patients after they have rested for a certain period following the removal of their NGT.

OBJECTIVE: To determine which factors affect the rehabilitation duration in patients with congenital muscular torticollis (CMT) and to predict the duration of rehabilitation and prognosis. METHODS: One hundred and eighteen patients (79 males and 39 females) who were diagnosed with CMT and received physical therapy were enrolled in this study. We retrospectively reviewed the information in terms of sex, gestational age, birth weight, methods of delivery, fetal presentation, age at diagnosis, the affected sternocleidomastoid (SCM) muscle site, SCM muscle thickness, ratio of muscle thickness on the affected side to that on the unaffected side (called the 'abnormal/normal [A/N] ratio'), and range of motion for cervical rotation and side bending. RESULTS: The SCM muscle thickness and A/N ratio had a positive linear relationship with the rehabilitation duration. Patients who were in the breech position needed longer rehabilitation. The birth weight and age at diagnosis were negatively correlated with the rehabilitation duration. However, the cervical range of motion, mass site, sex, gestational age, and methods of delivery were not correlated with the rehabilitation duration. CONCLUSION: Patients with a thicker SCM, lower birth weight, and history of breech delivery had a longer rehabilitation duration.

A ganglion cyst is a relatively common benign tumor on the wrist. Conservative and surgical approaches have been used for its treatment. Various conservative treatment methods have been suggested such as reassurance, aspiration, sclerosant injection, and direct compression. But, there is no acceptable treatment of choice yet because each suggested method has a relatively high recurrence rate. We want to report two cases in which the size of the wrist ganglion was decreased by using electroacupuncture. One patient presented with a chronic ganglion for six years and the other patient presented with a recently occurred acute ganglion. We applied electroacupuncture for 20 minutes once a week for eight weeks to both of them. Afterwards, the size of the wrist ganglion diminished in the follow-up sonography and the accompanying pain was also relieved. Herein we report both cases along with a review of the relevant literature.
