PURPOSE: To evaluate the effectiveness of a cycloplegic regimen using 0.5% tropicamide and 0.5% phenylephrine (Tropherine, Hanmi Pharm), in addition to 1% cyclopentolate, in hyperopic children. METHODS: The medical records of hyperopic patients below the age of 14 years who had undergone cycloplegic retinoscopy were retrospectively reviewed. Cycloplegic refractions were performed using one of two cycloplegic regimens. Regimen 1 was a Tropherine-added regimen comprising the administration of one drop of 1% cyclopentolate followed by two to three drops of Tropherine added at 15-minute intervals. Regimen 2 was a cyclopentolate-only regimen comprising the administration of three to four drops of 1% cyclopentolate at 15-minute intervals. The mean difference between noncycloplegic and cycloplegic refraction was compared between the two regimens. RESULTS: A total of 308 eyes of 308 hyperopic children were included. The mean difference (±standard deviation) in the spherical equivalent (SE) between cycloplegic and noncycloplegic refraction was significantly larger in regimen 2 than in regimen 1, with values of +1.70 ± 1.03 diopters (D) and +1.25 ± 0.89 D, respectively (p=0.001). The SE change after cycloplegia was significantly different between the two regimens only in patients aged 5 years or younger (p=0.001), particularly in those with high hyperopia with an SE ≥5 D (p=0.005) or fully accommodative esotropia (p=0.009). There was no significant difference between the two regimens in patients older than 5 years, regardless of the presence of high hyperopia or fully accommodative esotropia. CONCLUSIONS: The Tropherine-added regimen exerted a weaker cycloplegic effect than the cyclopentolate-only regimen, particularly in children under the age of 5 years with high hyperopia or fully accommodative esotropia. However, the difference in refraction between the two regimens was small. A Tropherine-added regimen can be effective in hyperopic children, with less associated discomfort than the instillation of cyclopentolate.

PURPOSE: The purpose of this study was to investigate the exercise participation experiences of colorectal cancer survivors. METHODS: A phenomenological method was used in this study. Ten adult colorectal cancer survivors were recruited and data were collected through in-depth interviews. RESULTS: The factors involved in the experiences of colorectal cancer survivors' exercise participation were categorized into 3 parts: (1) mental depression and isolation due to physical change, (2) barriers of exercise, (3) exercise participation for recovery. Though participants were aware of their changed body after cancer treatment and faced difficulties participating in exercise, they want to overcome these challenges through exercise participation. CONCLUSION: The results of this study show the exercise participation experiences of colorectal cancer survivors. Based on these findings, exercise maintenance can be promoted more effectively, and a higher exercise adherence of colorectal cancer survivors can be achieved.

Background: Meningococcal meningitis is a disease that can cause severe and possibly fatal side effects. To prevent the spread of meningococcal meningitis, which is a highly transmissible disease, 16 states in the USA mandate entering college students to receive meningococcal vaccination. Nevertheless, South Korea does not. This study aims to point out the importance of meningococcal vaccination by comparing the level of general knowledge and recognition of the requirement for vaccination among university students in the USA/Canada and Korea. Methods: The study was conducted using a self-filled questionnaire survey targeting international and Korean students at one of Korea's universities. The survey focused on topics such as knowledge of infectious diseases that can occur at the dormitory residence, infectious agents and routes of meningococcal meningitis infection and infection route, and students' intention to receive meningococcal vaccination. Results: International university students had a higher awareness of the importance of infectious disease prevention than Korean students (P<0.05) and also had higher meningococcal-related knowledge (P<0.05).International universities strongly recommend meningococcal vaccination compared to Korean universities (P<0.05), and the actual vaccination rate was higher than that of domestic university students (P<0.05). Conclusions This study found that the awareness of meningococcal vaccination among Korean university students was lower than that of international university students, and the vaccination rate was also lower. Because students often do not get vaccinated due to low awareness of the meningococcal disease, health education programs can increase their knowledge about infectious diseases and awareness of vaccines. Thus, increasing the vaccination rate.

Background: A considerable proportion of patients warranting total knee arthroplasty (TKA) have night pain, neuropathic pain, and/or depressive disorder, which may not be resolved by TKA. This prospective, longitudinal cohort study aimed to document the prevalence of night pain, neuropathic pain, and depressive disorder in patients with advanced knee osteoarthritis undergoing TKA and to determine whether the specific coexisting pain and/or disorder at the time of TKA adversely affected postoperative outcomes. Methods: In this study, 148 patients undergoing TKA were longitudinally evaluated. The presence of night pain, neuropathic pain (determined using Douleur Neuropathique 4 [DN4]) and depressive disorder (determined using the Patient Health Questionnaire-9 [PHQ-9]) was determined before and 6 weeks, 3 months and 1 year after TKA. In addition, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and EuroQol-5 Dimension (EQ-5D) scores were assessed before and 1 year after TKA. Potential associations of night pain, neuropathic pain, and/or depressive disorder with pre- and postoperative WOMAC and EQ-5D scores were examined in subgroup analyses. Results: Preoperatively, 72% (n = 106) of patients reported night pain, and the prevalences of neuropathic pain and depressive disorder were 15% and 17%, respectively. Preoperatively, compared with patients without night pain, those with night pain had significantly poorer preoperative WOMAC scores, but no significant difference was seen between groups 1 year after TKA. Preoperatively, the WOMAC, EQ-5D, and EQ-5D health scores of patients with neuropathic pain were not significantly different from those of patients without neuropathic pain, and there was no difference in clinical outcome scores 1 year after TKA between these groups. Preoperatively, the patients with depressive disorder showed significantly poorer preoperative WOMAC, EQ-5D, and EQ-5D health scores than those without depressive disorder, but no significant differences in scores were observed 1 year after TKA between these groups. Conclusion This study revealed a considerable prevalence of night pain, neuropathic pain, and depressive disorder in patients undergoing TKA and that patients with these specific conditions reported poorer functional and quality of life scores preoperatively. However, such adverse effects disappeared after TKA. Our study findings suggest that TKA can provide satisfactory outcomes for patients with these specific conditions.

Background: Vitamin D deficiency is a common challenge its consequences are studied to be related to diversity of other health concerns. The efficacy and safety in longevity of vitamin D3 B.O.N. 200,000 IU Intramuscular Injection were examined through investigator-initiated clinical trial. Methods: One-hundred and eight subjects between ages of 19 and 65 who showed vitamin D deficiency (serum 25(OH)D<20 ng/mL) were initially injected once and were checked every 3 months for the next 12 months for serum 25(OH)D and 1,25(OH)2D levels for the drug’s efficacy, and for other safety observations. The percentage of participants maintaining within the normal serum 25(OH)D range were analyzed. Participants who reduced in the serum level below 30 ng/mL during the regular visits were given additional injections. Results: All the subjects showed similar patterns of statistically significant improvements at all times. The percentage of participants remaining in the normal range was higher in the better compliance group. No serious adverse events or severe adverse reactions occurred. Conclusions Treatment of the vitamin D-deficient subjects with the injection of 200,000 IU vitamin D3 B.O.N. Intramuscular Injection induced a statistically significant increase in blood vitamin D concentration for 12 months demonstrating the clinical efficacy of the intervention. The higher percentage of the better compliance group being within normal ranges strengthens the evidence of the efficacy. No new adverse events or severe adverse events were associated with the injection, demonstrating its safety. Further studies to facilitate development of appropriate guidelines for interventions using vitamin D3 intramuscular injections will be desirable.

Venous anomalies, including portal vein thrombosis (PVT) and prior portosystemic shunts, are not uncommon in orthotopic liver transplantation (OLT) and require vascular reconstruction. PVT has been considered as a contraindication to OLT because of surgical complexity and increased postoperative morbidity and mortailty rates. Postoperative chylous ascites occur following disruption of abdominal lymphatics after retroperitoneal dissection. Chyloperitoeum after OLT is very rare. We report a case of piggyback OLT in a cirrhotic patient with portal vein thrombosis. A thromboendarterectomy was attempted first, and a venous jump graft was required between the donor portal vein and the infrapancreatic superior mesenteric vein. An aortic conduit was used for the hepatic arterial reconstruction. Retroperitoneal dissection was inevitable. Chylous ascites developed after the operation and were managed successfully with a low-at diet. In conclusion, we suggest that the presence of PVT is not a contraindication for OLT. Chylous ascites are rare after OLT, and the treatment of choice is a conservative one based on diet control.

PURPOSE: We examined whether fractional exhaled nitric oxide (FeNO) levels are associated with atopy profiles in terms of mono-sensitization and poly-sensitization in asthmatic children. METHODS: A total of 119 children underwent an assessment that included FeNO measurements, spirometry, methacholine challenge, and measurement of blood eosinophil count, serum total IgE, and serum eosinophil cationic protein (ECP). We also examined sensitization to five classes of aeroallergens (house dust mites, animal danders, pollens, molds, and cockroach) using skin prick testing. The children were divided into three groups according to their sensitization profiles to these aeroallergens (non-sensitized, mono-sensitized, and poly-sensitized). RESULTS: The geometric means (range of 1 SD) of FeNO were significantly different between the three groups (non-sensitized, 18.6 ppb [10.0-34.7 ppb]; mono-sensitized, 28.8 ppb [16.6-50.1 ppb]; and poly-sensitized, 44.7 ppb [24.5-81.3 ppb], P=0.001). FeNO levels were correlated with serum total IgE concentrations, peripheral blood eosinophilia, and serum ECP levels to different degrees. CONCLUSIONS: FeNO levels vary according to the profile of atopy, as determined by positive skin prick test results to various classes of aeroallergens. FeNO is also moderately correlated with serum total IgE, blood eosinophilia, and serum ECP. These results suggest that poly-sensitized asthmatic children may have the highest risk of airway inflammation.

We present a case of orthotopic liver transplantation in 63 year-old female patient with liver cirrhosis, who is the record of the oldest recipient in Korea. The donor was 20 year-old male patient with subarachnoidal hemorrhage. The operation time was 12 hours. The duration of cold ischemic time and anhepatic phase were 8 hours and 85 minutes respectively. After operation the patient resumed clear consciousness. The ventilator was weaned and removed. On the third postoperative day, reoperation was required due to hemoperitoneum. Splenectomy was performed for a tearing in the hilum. After reoperation, acute renal failure and sepsis developed. Continous arteriovenous hemofiltration was continued for 3 weeks. The patient was discharged on postoperative 59th day. The patient is doing well with normal liver function. No episode of acute rejection occurred until now. More aggressive approach has been feasible in organ transplantation for older patients by advanced knowledge of perioperative management. We conclude that age over 60 years should not be a barrier to liver transplantation.

Cyclosporine is an immunosuppressive agent that plays an important therapeutic role for organ transplantation. However, complications due to type 1 renal tubular acidosis, albeit rare, have been reported. We experienced a case of severe metabolic acidosis associated with cyclosporine administration after renal transplantation. A 54-year old man was hospitalized for seizure, confusion and weakness. He demonstrated severe metabolic acidosis and hypokalemia. Continuous renal replacement therapy was started and sodium bicarbonate was administered to correct the acidosis and the dosage of cyclosporine was reduced. Thereafter, the cyclosporine level in whole blood decreased gradually, and the metabolic acidosis improved.

Polyatreritis nodosa is a rare autoimmune disease (the immune system attacking its own body) characterized by spontaneous inflammation of the arteries (arteritis) of the body. Because arteries are involved, the disease can affect any organ of the body. The most common areas of involvement include the muscles, joints, intestines (bowels), nerves, kidneys, and skin. Gastrointestinal involvement is reported in about 50% of the cases, but bleeding complications are rare and result in a poor prognosis. Polyarteritis nodosa is most common in middle-age persons. Recently, we experienced polyarteritis nodosa which presented as small bowel bleeding and which was diagnosed by angiography, a small-bowel series, and patholgic examination of the surgically removed ileum specimen. We report this case with a brief review of the literature.
