  • Benign metastasizing leiomyoma(BML) is a rare condition affecting women with a history of having undergone hysterectomy or myomectomy for a benign uterine fibroid, that is found to have metastasized to extrauterine sites, usually many years after hysterectomy. 1,2) Patient with BML almost always asymptomatic, although if the lesions are large enough, they can cause compressive symptoms. Among several hypothesis of pathogenesis, most plausible theory is that these tumors represent a true metastatic lesion but are very low-grade sarcoma. 3) Because the tumor is responsive to estrogen, menopause and pregnancy have slowed the growth of these lesion 4) and it seems reasonable to perform hysterectomy in patients with a uterine mass and, at the same time, perform oophorectomy for hormonal control. BML is an unusual cause of diffuse pulmonary nodules which should be considered in females with unexplained nodules and a history of surgery for uterine leiomyoma.

  • Diffuse intrinsic pontine glioma (DIPG) is a deadly paediatric brain cancer. Transient response to radiation, ineffective chemotherapeutic agents and aggressive biology result in rapid progression of symptoms and a dismal prognosis. Increased availability of tumour tissue has enabled the identification of histone gene aberrations, genetic driver mutations and methylation changes, which have resulted in molecular and phenotypic subgrouping. However, many of the underlying mechanisms of DIPG oncogenesis remain unexplained. It is hoped that more representative in vitro and preclinical models-using both xenografted material and genetically engineered mice-will enable the development of novel chemotherapeutic agents and strategies for targeted drug delivery. This review provides a clinical overview of DIPG, the barriers to progress in developing effective treatment, updates on drug development and preclinical models, and an introduction to new technologies aimed at enhancing drug delivery.

  • Angiodysplasia is uncommon and frequently undiagnosed and presents a taxing surgical problem. It is usually diagnosed for unexplained gastrointestinal bleeding. Angiography gives a little information about wax and wane pattern of bleeding in the lesion. We experienced I case of angiodysplasia in G-I tract(especially colon) diagnosed in the Seoul National University Hospital. This report summarized our experience and review of east and west literature.

  • Kepler-47 is the first multi-body circumbinary planetary system detected by the Kepler space telescope. The two planets were detected by the transit method. In the discovery paper the authors report about the presence of an additional transit-like signal in their dataset which cannot be explained by a four-body (binary + 2 planets) system. Therefore it is likely that the unexplained signal could be due to a third planet. In this talk I will present recent results from a dynamical investigation of the five-body system (binary + 3 planets). We have applied the MEGNO technique to detect regions of quasi- or near quasi-periodic orbits of a hypothetical third planet. Quasi-periodic regions exists for a third planet and the long-term stability has been tested. Although the existence of a third planet is most likely to be confirmed from transit photometry we calculate transit-timing variation (TTV) signals due to the third planet which also can be used to infer its presence.

  • Abdominal epilepsy is an uncommon disorder and a rare cause of recurrent abdominal pain of children. Diagnostic criteria of this disorder include otherwise unexplained, paroxysmal gastrointestinal complaints, symptoms of a central nerve system disturbance, an abnormal electroencephalogram with a finding specific for a seizure disorder, and improvement with anticonvulsant medication. We present a case of a 6-year-old boy with abdominal epilepsy presenting with recurrent, paroxysmal abdominal pain for 4 years. This patient had definite electroencephalogram abnormalities and a striking response to administration of an anticonvulsant.

  • Pulmonary arteriovenous fistula can occur in a variety of clinical situations including liver diseases, infections, metastatic carcinomas, systemic disorders, and after the palliation of congenital heart diseases. A 72-day-old male infant with Tetralogy of Fallot and pulmonary atresia underwent surgical correction without difficulty. However, ventilator weaning in the ICU failed initially because of an unexplained postoperative hypoxemia(FiO2: 0.8, PaO2: 40 mmHg, SaO2: 80∼90%). Postoperative follow-up lung perfusin scan at postoperative 15 days showed right-to-left shunt(33.6%) and ventilator weaning was performed on the 20th day after the operation (FiO2: 0.4, PaO2, 50mmHg, SaO2: 86.9%). Arterial oxygen saturation under room air was 80∼85% at 7 months postoperatively. One and half year follow-up lung perfusion scan showed decreased amount of right-to-left shunt (11.2%). We report a case with a review of the literatures.

  • Diarrhea is the frequent passage of loose, watery stool (frequency: ${\geq}4/day$, weight: ${\geq}250g/day$) Most antibiotics can cause inflammatory change of the colon or Pseudomembranous colitis (PMC). Typical presentations of PMC are watery diarrhea, abdominal pain, fever, leukocytosis ($12,000~20,000/\textrm{mm}^3$), hypoalbuminemia, hypovolemia and recent or concurrent use of antibiotics. Diagnostic methods of PMC are stool assay, sigmoid scopy, abdominal CT, abdominal US, etc. The age-related susceptibility noted with PMC is impressive but unexplained. Two stroke patients had diarrhea, abdominal pain, fever hypoalbuminemia and a history of recent or concurrent use of antibiotics. By use of Shirhyung- Tang, we could improve clinical symptoms (diarrhea, abdominal pain, fever hypoalbuminemia, etc.) and so report clinical course of two stroke patients with antibiotics-associated PMC.

  • Objective: This report aimed to study fibromyalgia's diagnostic criteria, differential diagnoses and its pathology from the viewpoint of oriental medicine. Method: We observed and diagnosed a female patient who complained of prolonged whole body pain, even several times hospitalized for treatment. Result: The patient's symptoms correspond with fibromyalgia and we ruled out other suspected diseases. Conclusion: Fibromyalgia is prone to be misdiagnosed because the patient has complicated symptoms such as various pains and chronic fatigue as well as depression unexplained by medical tests. Furthermore, the symptoms often never disappear completely, although it isn't progressive or life-threatening, and can be improved. So accumulation of data and analysis from the viewpoint of oriental medicine is necessary for development of oriental medical standard treatment.

  • These experiments were carried out ot detect autoantiboies to zona pellucida in sera from infertile women using indirect ELISA and IFA and to investigate their effect on in vitro fertilization of mouse ova. In inidirect ELISA test, 12 of 116(10.3%) serum samples form infertile women gave positive reaction whereas all of 16 samples from fertile women and men were negative. Furthermore, in indirect IFA test, 17 of 116 (14.7%) serum samples from infertile women gave positive fluorescence whereas all of control sera were negative fluorescence. The fertilization rates(15.9%) of mouse eggs treated with positive sera were significantly lower than those(51.9%+71.2%) autoantibodies to zonapellucida are responsible for infertility in unexplained infertile women, presumably by perventing sperm attachment and penetration.

  • In the pediatric literature, excessive crying has been reported solely in association with 3-month colic and is described, if at all, as unexplained crying and fussing during the first 3 months of life. The bouts of crying are generally thought to be triggered by abdominal colic (over-inflation of the still immature gastrointestinal tract), and treatment is prescribed accordingly. According to this line of reasoning, excessive crying is harmless and resolves by the end of the third month without long-term consequences. However, there is evidence that it may cause tremendous distress in the mother-infant relationship, and can lead to disorders of behavioral and emotional regulation at the toddler stage (such as sleep and feeding disorders, chronic fussiness, excessive clinginess, and temper tantrums). Early treatment of excessive crying focuses on parent-infant communication, and parent-infant interaction in the context of soothing and settling the infant to sleep is a promising approach that may prevent later behavioral and emotional disorders in infancy.
