Choriocarcinoma associated with a normal pregnancy is rare. Futhermore, choriocarcinoma coexistent with a viable pregnancy is even rarer and associated with a greater risk of hepatic and cerebral involvement. So timely diagnosis of the disease is important for successful treatment and aggressive diagnostic procedures may therefore warranted. The patient should be treated with primary intensive combination chemotherapy(EMA-CO) and the selective use of irradiation and surgical therapy. We experienced a case of metastatic choriocarcinoma of lung and kidney following preterm delivery at 34th week of pregnancy and so present it with brief review of literature.

Functional mapping techniques including functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and magnetoencephalography (MEG) can be used to study the function of the nervous system. Optical imaging is an emerging technique for functional imaging of the nervous tissue. Functional optical imaging can be classified into two major streams; intrinsic signal optical imaging (ISO) and voltage-sensitive dye optical imaging (VDO). ISO is related to hemodynamic changes such as hemoglobin concentration and oxygenation changes, cytochrome oxidation change, and light scattering. On the contrary, VOD measures changes in membrane potentials of neural cells. Therefore, ISO reflects metabolic activity of neurons, while VOD directly reflects neural activity. Recent advances in optical imaging opened the possibility of its application to clinical situations as well as basic researches. Further, development of optical imaging may greatly contribute to the understanding of the function of the nervous system.

Chronic constipation is a very common disease in children. Successful treatment of constipation can be achieved not only with medication but also with lifestyle changes, including a proper diet. Diets including fruits, fluids, and probiotics are good for constipation. Some dietary components are helpful for constipation, and some are harmful. In this study, we present diets related to constipation from the literature, and propose some perspectives regarding diets related to constipation.

PURPOSE: Three-dimensional(3D) magnetic resonance(MR) projection imaging was evaluated as a noninvasive alternative to direct cholangiography for the assessment of its reliability in patients with obsructive jaundice. METHODS AND MATERIALS: A heavily T2-weighted gradient-echo sequence(PSIF) was used for 3D MR projecion imaging of the biliary system in five healthy volunteers and 25 patients with obstructive jaundice. The 3D images of the bile ducts were formed by stacking consecutive coronal MR images obtained with a fast imaging method to a maximum-intensity projection algorithm. RESULTS: In the volunteers, MR cholangiography could demonstrate the anatomy of the biliary tract in only two subjects. The extrahepatic and intraheparic bile ducts were well visualized in 23 patients with obstructive jaundice. The leve of obstruction and the grade of dilatation were dipicted with MR cholangiography in all cases. And the cause of obstruction could be determined with MR cholangiography in 18 cases, MR cholangiography was successful in two patients in whom ERCP failed. The gallbladder or dilated pancreatic duct not demonstrated by means of direct cholangiography was demonstrated with MR cholangiography in six cases.

PURPOSE: We evaluated the efficacy and safety of combined oral and enema therapy using polyethylene glycol (PEG) 3350 with electrolyte solution for disimpaction in hospitalized children. METHODS: We retrospectively studied 28 children having functional constipation who received inpatient treatment between 2008 and 2016. The amount of oral PEG 3350 electrolyte solution administered was 50–70 mL/kg/d (PEG 3350, 3–4.1 g/kg/d), and an enema solution was administered 1–2 times a day as a single dose of 15–25 mL/kg (PEG 3350, 0.975–1.625 g/kg/d). A colon transit time (CTT) test based on the Metcalf protocol was performed in some patients. RESULTS: Administration of oral and enema doses of PEG 3350 electrolyte solution showed 2.1±0.3 times and 2.9±0.4 times, respectively. After disimpaction, the frequency of defecation increased from 2.2±0.3 per week to once a day (1.1±0.1 per day). The number of patients who complained of abdominal pain was reduced from 15 (53.6%) to 4 (14.3%). Before hospitalization, nine patients underwent a CTT test, and 5 of 9 patients (55.6%) were classified as belonging to a group showing abnormalities. And in some patients, mild adverse effects were noted. We examined electrolytes and osmolality before and after disimpaction in 16 of 28 patients, and no abnormalities were noted. CONCLUSION: In terms of therapeutic efficacy and safety, combined oral and enema therapy using high-dose PEG 3350 with electrolytes is considered superior to conventional oral monotherapy or combined oral and enema therapy on an outpatient basis.

Hyperacute liver failure from mushroom intoxication in children is rare and has a low survival rate. We report a case of hyperacute liver failure from mushroom intoxication in a 29-month-old boy. The patient ingested a mushroom about three days prior to presentation. He was admitted to the hospital with vomiting, abdominal pain, seizures, and hematemesis. During the hospitalization the patient developed hepatic encephalopathy (stage IV-a), and a coagulopathy. He recovered fully with specific medication, Penicillin GK and N-acetylcysteine.

Constipation is one of the most common symptoms that a child visits pediatrician. The general approach to the child with functional constipation includes the following steps; disimpaction, maintenance and withdrawal of medication. There are many drugs which can be applied to children; osmotic agents (lactulose, sorbitol, magnesium hydroxide/citrate, polyethylene glycol with/without electrolytes, sodium phosphate, glycerin), stimulants (senna, bisacodyl, caster oil), lubricant (mineral oil), bulking agent (psyllium, cellulose, glucomannan). At each stage of treatment, one or some of these drug can be applied to the purpose. The author tries to summarize recent studies on drugs for constipation in child, and finally introduces new dugs for constipation which is under investigation.
