PURPOSE: This study was performed to investigate the epidemiology of enterovirus (EV) infections in children at a secondary hospital during recent 5 years. METHODS: We collected the cerebrospinal fluid, stool and throat swab samples from the pediatric patients with suspected EV infections in KEPCO Medical Center, Seoul, Korea from July 2006 to September 2010. EV detection and genotype identification were performed by RT-PCR at Korea Centers for Disease Control and Prevention. RESULTS: A total of 386 samples were collected from 277 patients during study period. Ninety-eight patients (35.4%) were diagnosed with EV infections. The RT-PCR positive rate was the highest in throat swab samples (48.3%). The median age of patient was 4.7 years (range, 0.1-12.5 years). Aseptic meningitis (50, 51.0%) was the most common clinical manifestation; herpangina (22, 22.4%) and hand-foot-mouth disease (18, 18.4%). One hundred EVs were isolated from 98 patients and 20 genotypes of EV were identified; Echovirus 30 (28 cases, 28%), Enterovirus 71 (12 cases, 12%), Echovirus 25 (10 cases, 10%), Echovirus 9 (9 cases, 9%) and Coxsackievirus A6 (8 cases, 8%). Aseptic meningitis caused by Echovirus 30 was the most common manifestation in 2008. There was no complicated case caused by Enterovirus 71. CONCLUSION: This study showed the epidemiology of confirmed EV infection in children from 2006 to 2010. There is a need for continuous surveillance of EV infections and its clinical manifestations.

Hand-foot-mouth disease (HFMD), one of the more distinctive rash syndromes, is most frequently caused by coxsackievirus A16, but can also be caused by enterovirus 71 (EV71) and other coxsackieviruses. Recently, there have been large outbreaks of simple, neurologically complicated and even fatal HFMD caused by EV71 in Western Pacific Area. However, in the Republic of Korea, despite its location in EV71 endemic Western Pacific Area, published reports on HFMD with EV71 are rare and there are no published reports on fatal cases. After the first fatal case of HFMD caused by EV71 announced in May 2009, much more cases of neurologically complicated HFMD have been announced. Even now, physician's increased awareness about the seriousness of HFMD, viral surveillance and early warning system of HFMD, and early detection and proper management of potentially life threatening HFMD caused by EV71 are required in the Republic of Korea, as in the neighboring countries.

Neisseria animaloris is a common flora in animals, but its pathogenicity is rarely reported. In this case report, N. animaloris was isolated from a hospitalized cat with pneumonia. The cat was discharged after testing and treatment with appropriate antibiotics. This paper reports the first case of N. animaloris pneumonia in Korea.

We examined the hepatitis G virus infections among 227 Koreans who were healthy or were suspected of hepatitis and determined the phylogenetic relationship based on a part of the NS-5 region of 5 positive samples. Viral RNA was extracted from sera and cDNA was synthesized and subsequently amplified by RT-PCR (reverse transcription-polymerase chain reaction) or RT-nested PCR using random hexamer and NS-5 specific primers (470-20-1-77F, 470-20-1-211R, HGVNESTFO, HGVNESTRE). Five positives were found to belong to samples of patients showing symptoms of viral hepatitis. Primers used for PCR or nested PCR were derived from the NS-5 region. On the other hand, no amplification was detected using primers derived from the 5'-NCR (G-146F, G-401R). We performed TA cloning and sequencing of 5 amplified fragments, and their sequences were compared with those of foreign isolates of HGV. The phylogenetic analysis using MegAlign programme of DNAstar has shown that the Korean isolates are clustered on the phylogenetic tree. In summary, we confirmed the hepatitis G virus infection in 5 cases out of 12 patients showing the symptoms of viral hepatitis. The phylogenetic analysis of sequences of 5 amplified fragments showed that their relations to each other were closer than those to the foreign HGV isolates reported.

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.

Human astrovirus (HAstV) is a major cause of acute diarrhea among children, resulting in outbreaks of diarrhea and occasionally hospitalization. Improved surveillance and application of sensitive molecular diagnostics have further defined the impact of HAstV infections in children. These studies have shown that HAstV infections are clinically milder (diarrhea, vomiting, fever) than infections with other enteric agents. Among the 8 serotypes of HAstV identified, serotype 1 is the predominant strain worldwide. In addition to serotype 1, the detection rate of HAstV types 2 to 8 has increased by using newly developed assays. HAstV is less common compared with other major gastroenteritis viruses, including norovirus and rotavirus; however, it is a potentially important viral etiological agent with a significant role in acute gastroenteritis. A better understanding of the molecular epidemiology and characteristics of HAstV strains may be valuable to develop specific prevention strategies.

Stone in the enlarged prostatic utricle is relatively rare and usually secondary to cystic dilatation of the utricle. Irritative lower urinary tract symptoms are the most common presenting complaint. Recently we experienced a enlarged prostatic utricle containing multiple stone and reviewed literature briefly.

A stellate ganglion block is frequently used in the pain clinic. It has been known that a stellate ganglion block maintains the homeostasis of hormones by improvement of blood supply to the brain. Therefore it has a systemic effect as well as a regional effect. Androgen, the sebaceous gland, hair follicle and bacteria are involved in pathogenesis of acne. The background for the treatment of acne with a stellate ganglion block can be related to the increase of blood supply to the face and the effect on the pineal gland. We administered a stellate ganglion block for the treatment of acne and had good results. From our experience, we consider a stellate ganglion block as the one of the effective treatment of acne.
