We report a case of esthesioneuroblastoma with intracranial extension treated with surgical resection and chemotherapy. A 5-year-old child presented with visual disturbance, and was subsequently found to have a huge sized mass in the anterior skull base, suprasellar region and lateral ventricle. A bifrontal craniotomy with excision of the tumor through subfrontal and interhemispheric approach was performed. The patient received postoperative chemotherapy according to Tandem protocol. A follow-up magnetic resonance(MR) image showed that the tumor showed partial regression, however, there was no change in tumor size in lateral ventricle. Second operation with excision of remnant mass through a transcallosal approach was performed. MR image, 9 months after first operation showed the postoperative change in frontal area without enhancing mass. By employing staged operation and chemotherapy, the authors obtained good results in the treatment of esthesioneuroblastoma with intracranial extension.

Eosinophilic gastroenteritis is an unusual disease characterized by eosinophilic infiltration of gastrointestinal tract, peripheral eosinophilia, and gastrointestinal symptoms. There are mucosal, muscular, and subserosal types, of which the subserosal type is the rarest. We experienced a 32-year old male patient with the subserosal type of eosinophilic gastroe-nteritis, who was presented with abdominal distension. The ascitic fluid revealed increased eosinophil count. With oral prednisolone, diarrhea and ascites rapidly disappeared and eosinophils in peripheral blood returned to normal. We report this case with a review of relevant literature.

Objective:
Exploiting their ability to differentiate into mesenchymal lineages like cartilage, bone, fat, and muscle, and to elicit paracrine effects, mesenchymal stem cells (MSCs) are widely used in clinical settings to treat tissue injuries and autoimmune disorders. One of accessible sources of MSC is the samples used for Papanicolaou (Pap) test, which is a cervical screening method for detecting potentially pre-cancerous and cancerous alterations in the cervical cells and to diagnose genetic abnormalities in fetuses. This study aimed to identify and isolate the stem cells from Pap smear samples collected from pregnant women, and to trace the origin of these cells to maternal or fetal tissue, and characterize their stem cell properties.
Methods:
To investigate the possibility and efficiency of establishing MSC lines from the Pap smear samples, we were able to establish 6 cell lines from Pap smear samples from 60 pregnant women at different stages of gestation.
Results:
The 3 cell lines randomly selected among the 6 established in this study, displayed high proliferation rates, several characteristics of MSCs, and the capacity to differentiate into adipocytes, osteocytes, and chondrocytes. Our study identified that the stem cell lines obtainable from Pap smear sampling were uterine cervical stromal cells (UCSCs) and had 10% efficiency of establishment.
Conclusion
Despite their low efficiency of establishment, human UCSCs from Pap smear samples can become a simple, safe, low-cost, and donor-specific source of MSCs for stem cell therapy and regenerative medicine.

Purpose:
The purpose of this study is to identify changes in knowledge, self-efficacy and anxiety achieved through the provision of video education on chemotherapy with a portable infusion pump to colorectal cancer patients.
Methods:
This study is a nonequivalent control group and non-synchronized design as a quasi-experimental study. Participants in this study were colorectal cancer patients who received chemotherapy with a portable infusion pump through an ambulatory care unit. For 48 subjects, the education was divided into printed materials and videos, and knowledge, self-efficacy, and anxiety were measured. Data were analyzed using independent t test, paired t-test, and Wilcoxon’s signed rank test.
Results:
In the video education group, knowledge (Z=-4.09, p<.001) and self-efficacy (Z=-2.72, p=.012) significantly increased after education, and anxiety significantly decreased after education (Z=2.24, p=.035). However, there was no difference in knowledge (t=0.09, p=.931), self-efficacy (t=1.22, p=.229), and anxiety (t=-1.16, p=.250) between the groups after education.
Conclusion
To improve the quality of life of cancer patients, it is necessary to promote self-efficacy and reduce anxiety. The results of this study suggest that more diverse educational methods should be attempted to improve knowledge and self-efficacy and reduce anxiety in colorectal cancer patients.

Pectus excavatum (PE) is known as one of the most common congenital deformities of the anterior chest wall. The Nuss procedure is an effective surgical therapy to correct PE. Here, we report a case of recurrent cardiac tamponade due to hemopericardium that occurred after 16 months following the Nuss procedure. The cause of recurrent hemopericardium was thought to be local, repetitive irritation of the pericardium by the Nuss steel bar. We should keep in mind that this serious complication can occur after the Nuss procedure, even in the late phase.

Background:
Copeptin is secreted in equimolar amounts as arginine vasopressin, main hormone regulating body fluid homeostasis. A recent study reported a copeptin-based classification of osmoregulatory defects in syndromes of inappropriate antidiuresis that may aid in prediction of therapeutic success. We investigated usefulness of copeptin for differentiating etiologies of hyponatremia and predicting efficacy and safety of hypertonic saline treatment in hyponatremic patients.
Methods:
We performed a multicenter, prospective cohort study of 100 inpatients with symptomatic hyponatremia (corrected serum sodium [sNa] ≤ 125 mmol/L) treated with hypertonic saline. Copeptin levels were measured at baseline and 24 hours after treatment initiation, and patients were classified as being below or above median of copeptin at baseline or at 24 hours, respectively. Correlations between target, under correction, and overcorrection rates of sNa within 24 hours/24–48 hours and copeptin levels at baseline/24 hours were analyzed.
Results:
Mean sNa and median copeptin levels were 117.9 and 16.9 pmol/L, respectively. Ratio of copeptin-to-urine sodium allowed for an improved differentiation among some (insufficient effective circulatory volume), but not all hyponatremia etiologic subgroups. Patients with below-median copeptin levels at baseline achieved a higher target correction rate in 6/24 hours (odds ratio [OR], 2.97; p = 0.02/OR, 6.21; p = 0.006). Patients with below-median copeptin levels 24 hours after treatment showed a higher overcorrection rate in next 24 hours (OR, 18.00, p = 0.02).
Conclusion
There is a limited diagnostic utility of copeptin for differential diagnosis of hyponatremia. However, copeptin might be useful for predicting responses to hypertonic saline treatment in hyponatremic patients.
