A 16-year-old female Shih-Tzu, weighing 5 kg, presented with clinical symptoms of abdominal distension and urinary and fecal incontinence. Abdominal palpation detected a large mass. According to the radiographic findings, the bladder had been moved to the umbilicus by the mass and a large abdominal mass was confirmed in the lower abdominal area. Ultrasonography indentified a large heterogeneous mass with heterogeneous parenchyma and a focal anechoic area in the lower abdominal area. The complete blood count abnormalities suggested thrombocytosis and mild neutrophilia, and the serum chemistry indicated an elevated alkaline phosphatase value. During laparotomy, a firm mass that measured $10.5{\times}9.6cm$ was found between the uterine cervix and urinary bladder. The urethra was embedded in the mass. A diagnosis of leiomyosarcoma was established based on histopathology and histochemistry. One week after surgery, urinary retention symptoms that did not appear to be related to mechanical obstruction presented suddenly, but they did not respond to several drug treatments, thus long-term conservative therapy was adopted. The urinary symptoms disappeared on day 27 and the patient started to void large quantities of urine in a smooth and frequent manner. This case report describes the serial changes in the patient's status and the response after surgical remove of the urethra embedding leiomyosarcoma.

From September 1994 to October 1995, we are reporting clinical results of 67 patients whom underwent video-assisted trio rabic surgery(VATS). 1. They were diagnosed as spontaneous pneumothorax In )5, diffuse interstitial lung disease in 9, empyema in 7, hemothorax in 5, malignant pleural effusion in 3, hyperhidrosis in 3, foreign body in chest cavity in 2, mesothelioma in 1, miliary tuberculosis in 1 and organizing pneumonia in 12. In pneumothorax, bullectomy in 33 and open bellectoiny in 2 due to pleural adhesion was done Hemostasis in 5, irrigation in 7, foreign body removal in 2, talcum powder insufrlation in 3, sympathectomy 3 as done. Thoracoscopic biopsy watt done In 12 3. For pneumothorax, operation was indicated as recurrent pneumothorax in 18, persistent air leak in 12, visible bullae In chest X-ray in 5. 4 Thoracoscopic biopsy was done in 12. They were interstitial pulmonary fibrosis in 9, miliary tuberculosis in 1, mesothelioma in 1, and organizing pneumonia in 1 .Among interstitial pulmonary fibrosis, usual interstitial pneumonia were 2 and diffuse interstitial pneumonia were 7. 5. Wo complication was found in 6) patients among 67 patients. The complication was found in 4 patients (2 persistent air leak, 2 contralateral lung atelectasis). We concluded that VATS was safe and beneficial in reducing postoperative complication and the role of thoracic surgery will increase markefdly.

Oligodontia is defined as the congenital absence of six or more teeth in dentition, excluding the third molars. The prevalence of congenital missing teeth is about 1.6 to 9.6% of population and the prevalence of oligidontia is about 0.08 to 1.1%. The mandibular second premolar is the most frequently absent after the third molar, followed by the maxillary lateral incisor and upper second premolar. Females seem to be affected slightly more than males. Oligodontia may occur either in isolation, or as a part of a syndrome such as ectodermal dysplasia. Different causes are possible for oligodontia: physical obstruction or distruction of the dental lamina, space limitation, functional abnormalities of the dental epithelium, failure of induction of the underlying mesenchyme, chemotherapy, radiotherapy or genetic factor. Because oligodontia would result in esthetic and functional problems, such as facial asymmetry or occlusal disharmony, early diagnosis from clinical and radiographic examination was necessary. And appropriate treatment plan should be followed. This case report was about oral conditions and treatment of the oligodontia patients who have no specific systemic disease.

Cleidocranial dysplasia(CCD) is a congenital disorder of skeletal and dental abnormality, which is mesodermal dysfunction influencing many tissues and organs. Skeletal abnormalities in CCD are delayed closure of cranial suture and fontanelle, presence of wormian bone and clavicle aplasia. And CCD has an effect on the long bones, phalanges, spine, pelvis, muscles, and central nervous system. Dental manifestations include retention of deciduous teeth, multiple supernumerary teeth, delayed or absent eruption of permanent teeth and formation of cysts around nonerupted teeth. But as a result in common with a lack of medical and physical disability patient may have no substantive complaint, there are many masticatory and psychological problem by absent eruption of permanent teeth after exfoliation of deciduous teeth. For this reason CCD is necessary fo early diagnosis and must be improvement of the patient's appearance as well as provision of a functioning masticatory mechanism by treatment of surgical removal of supernumerary teeth, followed orthodontically eruption of the natural permanent teeth at adequate time.

Myelodysplastic syndrome (MDS) is a typical myeloid malignancy characterized by cell dysplasia in bone marrow. Currently, there is no therapeutic treatment for MDS. The only available therapies either relieve symptoms or prevent the development of acute myeloid leukemia (AML). This study aimed to report the effects of traditional Korean medicine (TKM) on MDS by presenting two case reports. The patient in Case 1 was diagnosed with primary MDS and regularly received acupuncture treatments and herbal medicine. In Case 2, a patient with ovarian cancer was diagnosed with secondary MDS, which resulted from an adverse reaction to chemotherapy. This patient took herbal medicine for four years and was hospitalized three times. In order to have their condition evaluated, both patients underwent regular blood tests. The patient in Case 1, who showed blood transfusion dependency, received only two blood transfusions after TKM treatment, and the person’s health condition was stable as of January 2016 without any signs of AML development. The patient in Case 2 also has stable health condition. TKM treatment effectively treated their MDS symptoms and improved their general health conditions without any adverse effects. It also prevented the rapid development of AML and maximized the effects of conservative therapy.

There are few reports of the pleuropulmonary involvement of a non-typhi Salmonella infection in immunocompromised patients with AIDS, malignancy, collagen vascular diseases, extended use of corticosteroids, sickle cell disease, or diabetes. We report a case of a non-immunocompromised patient who presented with concomitant empyema and mediastinitis due to Salmonella without a comorbid disease. A 26-year-old male patient, with a history of pneumonia 5 years earlier and having lived abroad for several years, presented chronic cough and febrile sensation. Pneumonia, empyema and mediastinitis were noted in a chest CT scan and Salmonella enteritidis and ${\beta}-hemolytic$ streptococcus were identified from a culture of the pleural fluid. Initially, he was treated with cefepime, metronidazole and clarithromycin. He was cured clinically and radiographically after an 8 week treatment with antibiotics. In conclusion, this report suggests that S. enteritidis can cause empyema and mediastinitis, albeit rarely.

Factitious hemoptysis is the bleeding type of Munchausen's syndrome, and this describes a group of patients who intentionally produce symptoms. Because factitious hemoptysis is a very rare manifestation of hemoptysis, it generally passes unnoticed. We report here on a case of factitious hemoptysis in a 15-year-old boy who presented with hemoptysis. During his three hospitalizations, we conducted many diagnostic procedures, including chest CT, laryngoscopy, bronchoscopy and bronchial arteriography, yet we failed to find the definitive cause of the patient's hemoptysis. He kept on complaining of repetitive hemoptysis and seizure-like activity. His father discovered that he had collected his blood into the specimen cup via an intravenous line. After we removed the intravenous line, he did not show blood to us again. We suggest that factitious hemoptysis should be considered in the differential diagnosis of hemoptysis of an unclear bleeding focus, and especially when the patient has a bizarre hospital course or unusual behavior. We also include a review of the relevant literature.

Purpose: To evaluate the effect of oral sildenafil therapy in neonates with persistent pulmonary hypertension of the newborn (PPHN) Methods: We conducted a retrospective review of 32 neonates ${\geq}$35 weeks' gestation and fraction of inspired oxygen ($FiO_2$) 1.0 with PPHN. The first dose (0.5 mg/kg) of oral sildenafil was started and 1 mg/kg was given every 6 hour thereafter. Mean airway pressure (MAP), $FiO_2$, oxygenation index (OI), mean arterial blood pressure (MBP) were documented before and 6, 12, 24, and 48 hours after sildenafil. For adverse effects, gastrointestinal symptoms, brain ultrasound, funduscopy and auditory brainstem response results were evaluated. Results: The underlying diseases of PPHN (n=32) were meconium aspiration syndrome (n=9), respiratory distress syndrome (n=8), pneumonia (n=3), and idiopathic (n=12). Thirty-one neonates survived; 3 neonates were transferred for inhaled nitric oxide (iNO) and all of them survived. In 28 infants, $FiO_2$ and OI improved significantly by 6 hours and MAP improved significantly by 48 hours after initiation of sildenafil. There were no clinically significant adverse effects of sildenafil. Conclusion: Sildenafil may be an effective and safe agent for near-term and term neonates with PPHN, providing significant improvement in oxygenation, and thus may be especially useful in the treatment of PPHN in hospitals without iNO.

Purpose : To quantify the movement of lung Parenchyma for ICRU 50 Planning Target Volume (PTV) delineation of the lung region. Materials and Method : Fluoroscopic observations and measurements are Performed on 10 patients with chest region cancer who have normal putmonary functions We have divided the lung region into 12 parts for the right lung, 10 parts for the left lung and four to five Points of lung parenchyma were selected for anatomical analysis Points, Fluoroscopic images are sent to a computer and then movements are measured. Results : Both lowe lobes showed the longest longitudinal movements because of breathing (average 14.1mm, maximum 22.1mm), while anteroposterior displacement showed the smallest value. Lateral movements of the lung parenchyma averaged 6.6mm, and the maximum value was 9.1mm, (both hilar regions showed maximum values because of cardiac motion) Conclusion : We could quantify the lung movements by measuring parenchyma displacements. The movements of both upper lobes were less than those of the middle and upper lobes in longitudinal and transverse movements. Optimal margins can be selected for PTV delineation using these results.
