Purpose: Infantile hypertrophic pyloric stenosis (IHPS) is a common gastrointestinal disease in neonates and hypochloremia metabolic alkalosis is a typical laboratory finding in affected patients. This study aimed to analyze the clinical characteristics of infants with IHPS and evaluate the association of clinical and laboratory parameters with ultrasonographic findings. Methods: Infants diagnosed with IHPS between January 2017 and July 2022 were retrospectively evaluated. Results: A total of 67 patients were included in the study. The mean age at diagnosis was 40.5±19.59 days, and the mean symptom duration was 11.97±9.91 days. The mean pyloric muscle thickness and pyloric canal length were 4.87±1.05 mm and 19.6±3.46 mm, respectively. Hyponatremia and metabolic alkalosis were observed in five (7.5%) and 36 (53.7%) patients, respectively. Serum sodium (p=0.011), potassium (p=0.023), and chloride levels (p=0.015) were significantly lower in patients with high bicarbonate levels (≥30 mmol/L). Furthermore, pyloric canal length was significantly higher in patients with high bicarbonate levels (p=0.015). To assess metabolic alkalosis in IHPS patients, the area under the receiver operating characteristic curve of pyloric canal length was 0.910 and the optimal cutoff value of the pyloric canal length was 23.5 mm. Conclusion: We found a close association between laboratory and ultrasonographic findings of IHPS. Clinicians should give special consideration to patients with pyloric lengths exceeding 23.5 mm and appropriate fluid rehydration should be given to these patients.

A 3-year-old, male Shih-tzu dog with clinical signs of dysuria and hematuria was brought to the Veterinary Teaching Hospital. Chonnam National University. The patient was suspected urolithiasis by history taking and clinical signs but urinary and urethra calculus was not found in the radiographic examination. Enlarged prostatic gland (29.0$\times$28.0 mm) and severe finding of cystitis was observed from the ultrasonographic examination. The dog was finally diagnosed as the secondary urethral obstruction by benign prostatic hyperplasia. Castration was performed to treatment of acute hyperplasia of prostatic gland and prostatic cysts. After 26 days of operation, the prostate was defined small, hypoechoic, symmetric and decreased size (18.5$\times$18.0mm) by ultrasonography and dysuria cured completely.

Background: To determine the various sonographic findings in a papillary carcinoma of the thyroid. Materials and Methods: 48 patients with a proven papillary carcinoma of the thyroid were involved. The sonographic features analyzed were the size, shape, content, margin, internal echo, and calcification pattern. Results: Common sonographic features of a papillary carcinoma include the hypoechoic texture (94%), an ill defined margin (81%), a solid nodule (100%), irregular shape (48%), and microcalcifications (35%), or no calcifications (42%). The uncommon features included a hyperechoic or mixed echo texture, cystic elements, a well defined margin, and a coarse or peripheral calcifications. Conclusion: Ill-defined hypoechoic solid nodule with microcalcification is a characteristic ultrasonographic finding of a thyroid papillary carcinoma.

We reported a patient with a large pedunculated cavernous hemangioma located beneath inferomedial border of the scapular bone and the trapezius muscle checked by ultrasonography before and after the operation. In ultrasonographic finding, the peduncle was difficult to be visualized preoperatively due to acoustic shadowing.

A 20-year-old patient who got injured on his right big toe and complained pain visited to our hospital 9 months ago. Before the patient transferred to our hospital, plain radiographs were obtained at a private hospital and the patient underwent conservative treatment with uncertain diagnosis. However, the symptom was not improved, and he continued to complain intra-articular pain on his interphalangeal joint of big toe during plantarflexion or dorsiflexion. On plain radiographs of our hospital, we observed small bone fragment in his interphalangeal joint of the big toe. On the ultrasonographic images, two loose bodies in the interphalangeal joint were found. Then, we removed the loose bodies as surgical treatment, and the symptom was subsided completely. The purpose of this study is to report the ultrasonographic finding of the loose bodies of interphalangeal joint of the big toe.

A 10-year-old, spayed female, Doberman Pinscher dog presented with right forelimb lameness. On physical examination, painful reaction and crepitation were present at the right shoulder. Radiographic evaluation of the shoulder revealed nothing remarkable. On the ultrasonography of the right shoulder joint, 2 small echogenic masses accompanied by reverberation artifacts were observed in the right biceps tendon near its origin at the supraglenoid tuberosity. Based on these findings, we suspected biceps calcifying tendinopathy. Clinical signs resolved intermittently after administration of nonsteroidal anti-inflammatory drug. This study described the ultrasonographic findings of calcifying biceps brachii tendinopathy which is an unusual finding in dogs.

The effeciency of combined application of isotope scan and ultrasonography of thyroid was assessed in 91 patients with thyroid nodule. Malignancy rates were 35.5%, 18.8%, & 0% in solid, complex & cystic nodule group, respectively. No statistically significant co-relationship was found between isotope scan finding & ultrasonographic finding. Malignant nodules were found only in cold solid nodule group & cold complex nodule group, and rate of malignant nodule was different between them(45.8% in cold solid nodule group & 20.7% in cold complex nodule group). Difference between the rate of cystic change in benign & malignant nodule observed in our study(59.2% vs. 35.3%) was thought to explain at least partly the statistically different rate of malignant nodule in cold solid nodule & cold complex nodule group. No difference in the boundary condition, echogenicity & distribution of internal echo existed between benign nodule group &malignant nodule group.

A 4-year-old female Shih-tzu with severe episcleral congestion and buphthalmos in left eye was referred to the Veterinary Teaching Hospital, Chonnam National University in October 1998. During two months in local veterinary clinics, the dog had been treated unsuccessfully with tarsorrhaphy and antibiotics. By history taking, cause of the glaucoma was ascertained as accidental nonpenetrated cornea trauma by owner, Ophthalmic examination revealed that the left eye was buphthalmic with severe episcleral congestion, pain and fever. The direct pupillary light response could not be evaluated in the left eye, but right eye had normal reaction. The intraocular pressure was 4.5 mmHg in the right eye and 33 mmHg in the left eye, as measured with a Schiotz tonometer, Ultrasonographic finding revealed hyperechoic vitrous body and central echofree material. The Schirmer tear test showed 20 mm in the left eye and 8 mm in the right eye. The hematologic examination revealed monocytosis. The initial medical treatment was admitted, but there was no response. Transpalpebral enucleation in the left eye under inhalation anesthesia with enflurane 1.2 vol% in oxygen was performed. The day after operation the left eye ravealed no exudate, and pain, and the systemic vital signs were normal. The prognosis is excellent.

A laparoscopic wedge resection for a submucosal tumor, which is close to the gastroesophageal junction, is technically challenging. This can be a dilemma to both patients and surgeons when the tumor margin involves the gastroesophageal junction because a wedge resection in this situation might result in a deformity of the gastroesophageal junction or an injury to the lower esophageal sphincter, which ultimately results in lifelong gastroesophageal reflux disease. The patient was a 42 year-old male, whose preoperative endoscopic ultrasonographic finding did not rule out a gastrointestinal stromal tumor. He underwent a laparoscopic gastric wedge resection and prophylactic anterior partial fundoplication (Dor) and was discharged from hospital on the fifth postoperative day without any complications. There were no symptoms of reflux 5 months after surgery. A laparoscopic wedge resection and prophylactic anti-reflux surgery might be a good surgical option for a submucosal tumor at the gastroesophageal junction.
