A two-month-old female Thoroughbred foal was referred to the Equine Hospital, Jeju Stud Fm, Korea Racing Association. The foal was presented with opening of the abdominal ring by congenital predisposition. In physical examination, the foal revealed a mild heating, fluctuant swelling at umbilicus. The umbilical hernia was diagnosed, and then modified umbilical herniorraphy was performed and resulted in successful treatment. We conclude this method is of great value within the six-month-old foal with hernial ring size less than 10 cm.

A 13-day-old Thoroughbred female foal weighing 59 kg was referred to the Jeju National University Equine Hospital with clinical signs including depression, labored breathing, tachycardia, anorexia, and marked distended abdomen. Uroperitoneum secondary to a rupture of the urinary bladder was diagnosed based on the history, clinical signs, and ultrasound imaging. An emergency laparotomy for cystorrhaphy under inhalation anesthesia was performed, and the patient recovered uneventfully. A course of extensive supportive therapy with systemic antibiotics after surgery was carried out. The foal fully recovered and was discharged after 14 days of hospitalization. The follow-up after seven months revealed the patient to be clinically healthy. This report describes a case of uroperitoneum secondary to the rupture of the urinary bladder in a Thoroughbred foal, along with the clinical outcomes of surgical repair and intensive treatment in detail.

A five-day old female Thoroughbred foal appealed mild edema and pain of a lower eyelid on left eye. She was diagnosed with a typical entropion which clinical signs were inward rolling of the eyelid edge and excess lacrimation. Modified Hotz-Celsus technique that resect and suture only skin was operated. Result was very successful without recurrence of entropion and other complications. We conclude this method is of value for permanent correction of severe entropion in young foals.

Septicemic polyserositis and navel ill associated with Escherichia coli were reported in a 14-day-old male thoroughbred foal. The horse died after showing 12-day history of anorexia, lethargy, lameness and endophthalmus. Grossly, milky yellow abscesses were occupied in umbilicus, umbilical vein and artery. Large amounts of turbid pale yellow fluids were seen in pericardial sac, thoracic and abdominal cavity. Yellowish fibrinous materials were also presented in thoracic and abdominal cavity. Sticky pale yellow fluid and fibrinous materials were filled in stifle joint cavities of both hind limbs. Histologically, fibrino-purulent polyserositis and arthritis were observed. Severe omphalophlebitis with intra-lesional Gram negative bacterial colonies were noted in umbilical vein. Most of mesothelial cells in serosal cavities were severely hypertrophied. Pathogenic E. coli was purely isolated from ascites, thoracic and synovial fluids. Based on the results, the septicemic polyserositis may be originated from the umbilical cord infected with E. coli in this foal.

In this report, we described a case of acute colic with uterine rupture in a Thoroughbred broodmare during parturition. A 14-year-old broodmare showed acute colic characterized by rolling just after delivering of a healthy foal. Large intestine was prolapsed through vulva, contaminated with soil and its serosa was heavily damaged. We performed a euthanasia according to the owner's request. Post mortem examination revealed about 15 cm rupture on ventral side of the uterus. In addition, the orphan foal follow his owner after necropsy on his dam.

The most common abnormality of the umbilicus in the foal is the patent urachus. Patent urachus may be a congenital or acquired condition in foals in which the urachus fails to close spontaneously at or shortly after parturition. A 17-day-old male Thoroughbred foal was requested to the Veterinary Pathology Laboratory of Cheju National University. The foal showed clinical signs such as umbilical urination, anorexia, depression, lethargy, and abdominal pain for 10 days. Because of the umbilical urination, the surgery for patent urachus was performed, but he died next day. Grossly, many pale yellowish foci 10-20 mm in diameter were scattered on the throughout surface of lungs. Severe subcapsular hemorrhage was observed in left kidney. Large milky yellow mass 10X6-7 cm in size was found in the adjacent area of right kidney. Histopathologically, many abscesses with bacterial cocci were scattered in the blood vessels or adjacent pulmonary parenchyma of lungs. Severe numerous abscesses with intralesional bacterial cocci were mostly occupied in the abdominal mass from right kidney. Gram staining for tissue sections demonstrated numerous Gram positive cocci in pulmonary and abdominal abscesses. In bacterial culture, catalase-positive beta-hemolytic colonies were isolated and confirmed as Staphylococcus (S.) aureus by Vitek system. Based on the results, acquired patent urachus and then multiple abscesses may be originated from the umbilical cord infected with S. aureus in this foal.

Angular limb deformities (ALD) are common in foals. A 30-days-old Thoroughbred foal was presented for the evaluation of severe ALD of the both forelimbs. On radiographic examination, both distal radiuses were diagnosed as valgus angular limb deformities. But the degree of deviation of right forelimb was so severe that we tried to correct one after the other. We tried new surgical correction method combination of one screw implant on medial aspect for growth retardation and periosteal transection on lateral aspect of the right forelimb. 40 days later, successfully corrected and then removed the screw. After the right forelimb correction, the periosteal transection on left forelimb was performed. We did the inhalation anesthesia using isoflurane. There were no complications such as fibrosis over the screw heads, and overcorrection that produces an opposing deformity identified. These results suggest that combination of one screw implant and periosteal transection technique is able to be a safe and effective method to correct severe ALD in the foal.

Two 4-day-old Thoroughbred foals with acute clinical signs of depression, elevated pulse and respiratory rates, anemia, and jaundice were referred to the equine hospital of Korea Racing Authority. The foals were seemingly normal at birth, but showed clinical signs such as abnormal behavior, jaundice and anemia suddenly after ingestion of the mare's colostrum, followed by death at 4 days after birth. According to the results of the hematology, serum chemistry analysis, jaundice foal agglutination test, and blood groups test, the foals were diagnosed as neonatal isoerythrolysis (NI) caused by the mare's antibodies. These results suggested that the pregnant mares have a potential for NI.

A 2-day-old Thoroughbred foal weighing 58 kg was admitted to the Equine Hospital of Korea Racing Authority (KRA) Jeju Stud Farm with clinical signs including loss of suckling behavior and barking. Neonatal encephalopathy (NE) was diagnosed based on history and typical clinical signs of NE. The foal seemed to recover in 5 days of intensive care and treatment but then was complicated with the septic arthritis of left hock joint on the $6^{th}$ day of admission. A course of aggressive systemic antimicrobial therapy with joint lavage for 8 days was conducted and the foal was fully recovered and discharged. The follow up on the patient after 2 years revealed that the patient achieved a great success as a racehorse without any unexpected sequel. This report describes a course of NE complicated with septic arthritis in a foal and the clinical outcome of the intensive care and treatment in detail. To our knowledge, this is the first report which describes NE complicated with septic arthritis in a foal in Republic of Korea.

A 4-month-old female thoroughbred foal was presented with large mass on mandibular gingiva. The enlarged mass was firm and yellowish pink in color, and occupied the whole mandibular arcade. The filly could not close her mouth with her lips. Radiographs showed radioopaque mass under the mandible. The mass was surgically excised from mandible. Histopathologically, gingival mass was characterized by hyperplastic gingival epithelium, well vascularized collagenous stroma and large area of bony tissues. Based on the gross and histopathologic findings, this case was diagnosed as ossifying epulis in the mandibular gingiva. This is the first report of ossifying epulis in a thoroughbred horse in Korea.
