This study was performed to evaluate the ultrasonographic findings of ethylene glycol intoxication. Ten healthy mongrel dogs which was administered with ethylene glycol, were evaluated in terms of clinical findings, hematological findings, blood chemistry, and ultrasonographic and histopathological findings of kidney. The results obtained through these experiment could be summarized as follows : 1. Typical clinical symptoms such as vomiting, initial apprehension, depression, thirst, dehydration, tremor, anorexia, hematuria, anuria, weakness, weight loss, flaccid paralysis, tachypnea, coma, and death, were revealed after administration of ethylene glycol. 2. Special symptom of bloody diarrhea was occurred by administration of ethylene glycol. 3. After administration of ethylene glycol, PCV was decreased continuously(p<0.01), and total leukocyte count was increased gradually, revealed the highest value at day 5 and thereafter decreased. 4. Remarkable changes of ultrasonographic findings such as high echo intensity of renal parenchyma and emergence of halo in corticomedullary junction, were revealed after administration of ethylene glycol. Early(hour 8) enlargement and late(day 3) enlargement were observed in kidney(p<0.01). Especially, late enlargement was observed concurrently with the elevation of BUN and creatinine values. 5. Calcium oxalate crystals, metabolites of ethylene glycol, were observed in histopathologic findings of kidney. Also, degeneration and necrotic exfoliation of epithelial cells were recognized in addtion to swelling of renal tubules.

Purpose: To describle clinical features and enzyme activity of Vietnamese patients with Mucolipidosis type II. Methods: Clinical features, laboratory and plasma lysosom enzyme activity by 4 MU-Fluorometric assay was studied from 2014-2015 at the Northern referral center of Pediatrics - National Children's Hospital. Results: 16 cases (7 girls and 9 boys) were diagnosed with I-cell bases on clinical symptoms and enzyme activities studies. Diagnosis age was $5.93{\pm}4.28$ years, onset age was recognised from birth to 4 years (median 1.25) with the feature of joint stiffness and bone deformation. All cases presented with the feature of joint stiffness, chest deformation and kyphoscoliosis; Fifteen cases (93.7%) had coarse facial features. No patients had hepatosplenomegaly on abdominal ultrasound, 5/15 patients had heart valves disease. Enzyme assay showed ${\alpha}$-Hexosaminidase of $1,885.9{\pm}338.7$ (nmol/mg plasma/17 hrs), ${\alpha}$-Iduronate sulfatase of $4,534.8{\pm}1,062.9nmol/mg$ plasma/4 hrs). Conclusion: Mucolipidosis II seriously affected the life of the patients with skeletal deformities, contractures develop in all joints and cardiac involvement.

A 2-year-old female Maltese dog was presented with a history of anemia and vaginal hemorrhagic discharge. Physical examination revealed severe vaginal hemorrhagic discharge, abdominal pain, pale mucous membranes, low blood pressure and dehydration. Results of serum biochemistry, hematology, venous blood gas, and electrolyte canine C-reactive protein (CRP) test revealed severe normocytic normochromic anemia, severe neutropenia, a high level of CRP, hypoglycemia, and imbalanced electrolytes. Abdominal ultrasound examination showed focal hypoechoic defect with loss of layering in uterine horn wall. A laparotomy revealed a clear reddish fluid in the abdomen, the fistula of left and right uterine horn, the purulent discharge from fistula, and symptoms of septic peritonitis near by the fistula site. The bitch underwent ovariohysterectomy and recovered without complication. Histopathological diagnosis of the uterine fistula site was adenocarcinoma.

Congenital chloride diarrhea (CLD) is a rare inherited autosomal recessive disorder. Mutations of the solute carrier family 26 member 3 gene cause profuse, chloride ion rich diarrhea, which results in hypochloremia, hyponatremia and metabolic alkalosis with dehydration. If a fetal ultrasound shows bowel dilatation suggestive of bowel obstruction, or if a neonate shows persistent diarrhea and metabolic alkalosis, CLD should be considered in the differential diagnosis. The severity of CLD varies, but early detection and early therapy can prevent complications including growth failure. We report a case of dizygotic twins affected by CLD who had been born to non-consanguineous parents. Both of them showed growth failure, but one of the twins experienced worse clinical course. He showed developmental delay, along with dehydration and severe electrolyte imbalance. He was diagnosed with CLD first at 6-month age, and then the other one was also diagnosed with CLD.

Inflammatory conditions of the breast are uncommon and may be encountered in the puerperal and nonpuerperal setting. Nonpuerperal mastitis is less common and usually presents with inflammation and chronic abscess formation in the periareolar and peripheral region. These abscess have a high rate of recurrence and are often associated with an underlying disease state, such as diabetes, steroid treatment, trauma or other kinds of a deficient immune system. The diagnosis is suggested by the history of sudden onset and the presense of swelling, tenderness, heat, erythema, and in the case of abscess, fluctuation. Ultrasound can also be useful. Treatment consists of antibiotic administration or incision and drainage of the abscess and, in cases of retroareolar abscess, resection of entire underlying duct system. Recently, we have gotten good result from treating two cases of nonpuerperal mastitis and breast abscess which had treatment of antibiotics and drainage three times but recurred. After taking gamijipaesan(加味芷貝散) and acupuncture treatment, they have recovered and haven't recurred in 8 months. So it proves that herb medication and acupuncture are effective on nonpuerperal chronic mastitis and breast abscess.

Partial hydatidiform mole and coexisting fetus is a rare entity with antecedent high risk of maternal and fetal complications, and risk of persistent trophoblastic disease in later life. Here, we report a case of twin pregnancy with live fetus identified as 45,X and normal placenta and another partial mole. Ultrasound scan at 10 weeks showed a hydrops fetus with a focal area of multicystic placenta. The patient underwent chorionic villus sampling and amniocentesis for chromosomal analysis, and the result was 45,X. Based on these finding, the patient then underwent induced abortion. Pathological examination (immunohistochemical staining) of the placenta confirmed the partial mole. This report suggests that careful prenatal ultrasonography and appropriate karyotyping in a molar pregnancy and coexisting fetus enable early diagnosis and may be beneficial for prognosis.

This study aimed to report a case of infant who presented with a prenatal ultrasound diagnosis of agnathia, polyhydramnios followed by a review of previous studies. As widely acknowledge, agnathia is a complex lethal malformation characterized by absent mandible, microstomia, microglossia and ear anomaly which are secondary results to a defect of the first branchial auh. Newborn infants with agnathia often suffer from airway obstruction, causing fatal respiratory failure. The most difficult part of treating those newborns is to keep the airway patent. Therefore, as early airway management planning as possible is the most important part. Airway management was achieved with tracheotomy through an ex utero intrapartum treatment procedure(EXIT). The case of this infant, reporting here, was underwent tracheotomy with preservation of uteroplacental blood flow and gas exchange.

Gastrointestinal stromal tumors (GISTs) are the most common primary mesenchymal neoplasms of the gastrointestinal tract and usually appear as a well-circumscribed mass. However, it may be difficult to confirm the extent of the disease for some GISTs. A 70-year-old asymptomatic female presented for a regular physical exam. An esophagogastroduodenoscopy showed a 2.0 cm protruding mass on the gastric fundus. Endoscopic ultrasound revealed an ill-defined heterogenous hypoechoic lesion ($3.0{\times}1.5cm$). A computed tomography (CT) scan demonstrated a 4.5 cm multifocal calcified mass at the gastric body as well as at the gastric fundus. Laparoscopic gastric wedge resection was performed according to the extent of multifocal calcifications that are shown on the CT. Intraoperative specimen mammography and intraoperative biopsy might be helpful to obtain a tumor-free margin. Final pathologic diagnosis was an intermediate risk GIST in multilobular form. In patients with diffuse multifocal calcifications in the stomach, the possibility of GIST should be considered.

To diagnose cardiac malfunctions, various imaging techniques have been applied to heart : DSA(Digital Subtracted Angiography), Doppler Ultrasound, MR Angio. But it is difficult to observe three dimensional heart motion which is the most intuitive tool for diagnosis, only by using these methods. In this research, we have suggested 4-Dimensional reconstruction scheme of heart motion images that can be acquired by ECG-gated cine MR imaging. One cardiac cycle was devided into $9\sim15$ phases and for each phase 3D reconstructed volumn heart was made. We can observe 3D volumns along the cardiac cycle, time. So the results were 4-D reconstructed data.

Digital fetal monitoring system based on the personal computer combined with the digital signal processing board was implemented. The DSP board acquires and digitally processes ultrasound fetal Doppler signal for digital rectification, FIR filtering, autocorrelation function calculation, its peak detection and MEDIAN filtering. The personal computer interfaced with the DSP board is in charge of graphic display, hardcopy, data transmission and on-line analysis of fetal heart rate change including and variability. I used a recursive technique for autocorrelation function computation method and MEDIAN filter which can greatly reduce the amount of calculation and accuracy. I also implemented analysis algorithm of fetal heart rate change based on normal fetal sample data in order to exact diagnosis.
