Enterobiasis and head lice infestations, contact-borne parasitic diseases, are the most prevalent parasitic infections of children in Korea, and they are transmitted by close contact with infected persons. They are not of major concern in public health, therefore their importance in children's health care are overlooked in Korea. Egg positive rates of Enterobius vermicularis have been reported to be 10~20% among children in kindergartens and primary schools. Enterobiasis is diagnosed by scotch tape anal swab, but repeated examination is necessary for accurate diagnosis. Albendazole or mebendazole are extremely effective for treatment, however, reinfections usually occur if treatment is not repeated at least three times at a 3-week-interval, targeting the whole family members including the patients. Environmental sanitation and health education are also necessary to guarantee the successful treatment of enterobiasis. Head lice infestation is still an indication of public health status. Children of 3 to 12 years old and their families have infestations more frequently, and girls have more than boys. Diagnosis can be made by identification of live lice or nits on the head. Pediculicides are effective treatment of infestations, however they do not kill nits completely, requiring second treatment. Recently wet combing is preferred as an alternative by parents in England because of possible toxicity of drugs and resistance of lice. It is impossible to completely prevent enterobiasis and/or head lice infestations. Therefore, mass screening and prevention are required, and, in local clinics, a thorough evaluation of the symptoms and past history, and appropriate laboratory tests are necessary.

An intra-articular osteoid osteoma is a very rare cause of elbow pain, and its diagnosis and treatment remain challenging. Delayed diagnosis may lead to arthritic change of the joint. In this study, the authors present the occurrence of intra-articular osteoid osteoma in the right elbow of a 15-year-old male patient who presented with prolonged pain and limited motion owing to delayed diagnosis. After confirming the nidus of osteoid osteoma from radiographic evaluation, the lesion was completely removed arthroscopically. The patient presented a complete relief of symptoms and full range of motion. This is the first domestic report of successful arthroscopic treatment of an intra-articular osteoid osteoma of the elbow.

Symptoms of caliceal diverticular stones are commonly associated with pain, recurrent urinary tract infection and hematuria. The aim of this study is to select the proper patient for the application of more successful extracorporeal shock wave lithotripsy(ESWL) as a treatment of caliceal diverticular stone. 16 patients with caliceal diverticular stones were treated with ESWL, and all patients had single caliceal diverticulum. The diagnosis of caliceal diverticulum with stones was made by intraveneous pyelography to all patients. On these intravenous pyelogram, we also classified diverticular type, whether the diverticular neck is connected with urinary tract patently, diverticular site and stone number and size. All patients were followed after ESWL by plain film of the kidneys, ureters and bladder and interviewed. Of all patients 44% was shown stone-free completely, also 83% was rendered symptom-free. All patients whose diverticular neck connected with urinary tract patently on the intraveneous pyelogram became stone- free. Of solitary stone 60% and multiple stones(more than 2) 17% became stone free. All patients rendered stone-free became symptom-free, and of patients with residual stones 44% became symptom-free. The patients with infection before ESWL 75% had residual stones, of these patients 33% had slightly flank pain, and 25% of patients with stones recurred become stone-free. We propose that more successful ESWL for patients with caliceal diverticular stones select satisfactory patients including that the diverticular neck is connected with urinary tract patently, solitary stone and no infection simultaneously.

In these days there are many troubles - system data error, control malfunctions, cable overheating - in water treatment plant. Specially DAF(Dissolved Air Floation Process) plant has high frequency than previous water treatment process. DAF plant has diverse equipment, nonlinear loads for the precise control. But there is no sufficient overall study about harmonics condition of water treatment plant just taking a following partial action without a fundamental solution. On designing of power system, designer should have regard to harmonics condition, but there is no guide reflected harmonics condition on DAF plant This study says what is the result of guideless design about harmonics. With the result of diagnosis and analysis in DAF plant, economical efficiency and safety of plant will be upgraded in the next design.

The rise in chronic disease not only has a negative effect on people's lives, but it also increases the cost of medical care owing to the increased usage of medical care as health and medical technology improves, life expectancy rises, and rapid population ageing. In such context, this study examined the difference in the disease cost of hypertension according to demographic information and the effect of the initial diagnosis age and treatment period on the cost. This study used the Korean Health Panel Survey from 2010 to 2017, and selected subjects based on health insurance beneficiaries between the ages of 30 and under 80. With the selected data, the direct and indirect costs of disease loss were calculated according to the cost of illness approach, and we constructed a disease-loss ratio cohort considering the age of diagnosis and time of treatment for hypertension. From the results of the study, the annual cost of disease loss for hypertensive patients differed by gender by 110,107 won, and it was found that the cost increased by 1.8 times as the treatment time increased. In addition, when comparing disease loss ratios between the same age groups, it was found that the disease loss ratios between those in their 60s and 70s were affected by treatment time. This study confirmed that hypertension significantly affects the cost of the disease, and not only requires early diagnosis and management, but also preventive efforts to lower the incidence of hypertensive disease must be strengthened.

A 4 year old female with acute lower abdominal pain was admitted with the diagnosis of periappendiceal abscess made by ultrasonography. At laparotomy, the appendix was normal, but the left ovary was twisted and necrotic. Appendectomy and left salpingo-oophorectomy were performed. The pathology of the appendix was normal, and the left tube and ovary were ischemic and had hemorrhagic necrosis. Pediatric adnexal torsion may be difficult to diagnosis clinically. Sonography is the preferred imaging study. It usually confirms a pelvic mass but may not establish the diagnosis. The correct diagnosis of adnexal torsion is often made at exploration. The most common erroneous diagnosis is acute appendicitis or periappendiceal abscess. Therapy for adnexal torsion remains controversial. While extirpation has been the standard of treatment in the past, there are current proponents of conservative therapy with adnexal sparing. Early diagnosis may lead to more frequent salvage of affected adnexa.

It is important to distinguish deformational plagiocephaly from craniosynostosis, the two conditions are different with respect to clinical progression and treatment options. Deformational plagiocephaly is diagnosed based on the patient's medical history and physical examination. Until recently, there has been no standardized method of evaluation. Visual assessment, anthropometric assessment, digital scanning, and radiologic evaluation are mostly commonly used modalities for diagnosis and assessment. Treatment of deformational plagiocephaly requires an understanding of natural progression of the disease. Deformational plagiocephaly should be classified according to its severity before the proper method and time for treatment are determined. Treatment includes repositioning, physiotherapy and remodeling with the use of orthotic devices. In general, repositioning is preferred for patients younger than six months old while treatment with the use of orthotic devices such as helmet is preferred for patients over six months old. Moreover, treatment with the use of orthotic devices is also favored for severe plagiocephaly. There is continuing research on the relation between deformational plagiocephaly and developmental delay.

Objective: The aim of the current study was to evaluate changes in treatment outcomes in terms of health-related quality of life (HRQoL) and symptom burden at zero, one, three, and six months after an initial diagnosis of colorectal cancer. The demographic and clinical characteristics that account for outcome changes in patients were investigated using a repeated measures framework. Methods and Materials: A cohort study was performed of 134 colorectal cancer patients followed from diagnosis to 6 months post-treatment in Central Taiwan. HRQoL and symptoms were assessed at diagnosis and one, three, and six months thereafter. The Functional Assessment of Cancer Therapy-Colon (FACT-C) questionnaire, VAS pain, and the Memorial Symptom Assessment Scale (MSAS) were used for data collection. A generalized estimating equation (GEE) was applied for statistical analysis. Results: The majority of the patients were male (55%) and married (91.5%). The mean age was 60.4 years (SD = 11.71). Most were diagnosed stage III and IV colorectal cancer (54.5%). All underwent surgery; some also received chemotherapy (CT) or concurrent chemoradiation therapy (CCRT). The results of the GEE showed that overall, the HRQoL, pain, and symptoms of the patients significantly improved over the treatment period. Patients with stage IV disease who had received surgery and CCRT showed the worst HRQoL. Females, patients with comorbidity, and stage IV patients had higher pain scores over time. Female and stage IV patients had more severe physical symptoms, whereas stage II and IV patients had worse psychological symptoms over time. Conclusion: The patients' HRQoL, pain, and symptoms significantly improved over the 6-month treatment period. Certain patient and clinical variables accounted for changes in treatment outcomes regarding HRQoL and symptom burden in colorectal cancer patients.

For patients with bimaxillary protrusion, significant retraction and intrusion of the anterior teeth are sometimes essential to improve the facial profile. However, severe root resorption of the maxillary incisors occasionally occurs after treatment because of various factors. For instance, it has been reported that approximation or invasion of the incisive canal by the anterior tooth roots during retraction may cause apical root damage. Thus, determination of the position of the maxillary incisors is key for orthodontic diagnosis and treatment planning in such cases. Cone-beam computed tomography (CBCT) may be useful for simulating the post-treatment position of the maxillary incisors and surrounding structures in order to ensure safe teeth movement. Here, we present a case of Class II malocclusion with bimaxillary protrusion, wherein apical root damage due to treatment was minimized by pretreatment evaluation of the anatomical structures and simulation of the maxillary central incisor movement using CBCT. Considerable retraction and intrusion of the maxillary incisors, which resulted in a significant improvement in the facial profile and smile, were achieved without severe root resorption. Our findings suggest that CBCT-based diagnosis and treatment simulation may facilitate safe and dynamic orthodontic tooth movement, particularly in patients requiring maximum anterior tooth retraction.

Cardiac myxoma is most significant benign tumors constituting nearly 50% of all primary cardiac tumors. Its diagnosis is important because prognosis is excellent by surgical therapy and is usually fatal if unrecognized and untreated. Recently the development of diagnostic procedure and cardiac surgery increased the accuracy of diagnosis and the opportunity of successful treatment. Two cases of left atrial myxoma removed successfully were presented.
