Infectious bovine keratoconjunctivitis (IBK) is the most common ocular disease in cattle, manifesting as corneal opacity, corneal ulcerations and potentially vision loss. The present report describes a 10-month-old Holstein Friesian heifer with IBK treated by systemic tulathromycin, and subconjunctival injection of penicillin and dexamethasone. We investigated changes in the hematological indices and microorganisms related to IBK after treatment. Neutrophils and monocytes decreased during recovery, so it was assumed that these two types of white cells are associated with IBK. Moraxella bovoculi was cleared in the eye, nasal cavity, and oral cavity after treatment. The distribution of M. bovoculi before treatment indicated that a combined systemic and subconjunctival treatment was necessary. The lesioned eye was found to be overwhelmed by Mycoplasma bovoculi, while pathogen abundance was reduced in the nasal cavity and oral cavities. These results suggest that antibiotic treatment can alter the composition and relative abundance of microorganisms.

Sjögren syndrome is a chronic autoimmune inflammatory disease characterized by lymphocytic infiltration of exocrine glands, predominantly the parotid and lacrimal glands, thereby resulting in oral and ocular dryness. It has been reported to occur most frequently in women between 40 and 50 years of age. Sjögren syndrome has an insidious onset, is slowly progressive, and presents a wide range of clinical manifestations, leading to delays or challenges in the diagnosis. Early diagnosis of this condition is essential to prevent the associated complications that affect patients' quality of life. This report presents 3 cases of Sjögren syndrome in female patients aged between 40 and 75 years who presented with complaints of persistent dry mouth and burning sensation. The cases highlight the diagnostic value of 3-dimensional cone-beam computed tomographic sialography in the detection of salivary gland pathologies at an early stage.

Allergic rhinitis is a common disease of childhood characterized by nasal, throat, and ocular itching, rhinorrhea, sneezing, nasal congestion. Those affected with allergic rhinitis often suffer from associated inflammatory conditions of the mucosa, such as allergic conjunctivitis, rhinosinusitis, asthma, otitis media with effusion, and other atopic conditions, such as eczema and food allergies. Allergic rhinitis must be diagnosed and treated properly to prevent complications and impaired quality of life. Despite a high prevalence, allergic rhinitis isoften undiagnosed and inadequately treated, especially in the pediatric population. The first step in treatment is environmental control when appropriate. It may be difficult to eliminate all offending allergens effectively to reduce symptoms, so medications are often required. Many different classes of medications are now available, and they have been shown to be effective and safe in a large number of well-designed, clinical trials. Antihistamines are effective in treating immediate symptoms of sneezing, pruritus, watery eyes, and rhinorrhea. Second generation antihistamines are the preferred antihistamines because of their superior side effect profile. Thus, decongestants are commonly used with oral antihistamines. Intranasal corticosteroids are the most effective therapy for allergic rhinitis. Leukotriene modifier may be as effective as antihistamines in treating allergic rhinitis symptoms. Cromolyn sodium is an option for mild disease when used prophylactically, and ipratropium bromide is effective when rhinorrhea is the predominant symptom. When avoidance measures and medications are not effective, specific immunotherapy is an effective alternative. Only immunotherapy results in sustained changes in the immune system. Because of improved understanding of the pathogenesis, new and better therapies may be forthcoming. The effective treatment of allergic rhinitis in children will reduce symptoms and will improve overall health and quality of life, making a happier, healthier child.

Myasthenia gravis is a functional neuromuscular disorder with characteristic voluntary muscle weakness. The role of thymus in pathogenesis of this disorder has become apparent that thymectomy in treatment has gained acceptance. Between January 1976 and June 1987, twenty patients underwent thymectomy for myasthenia gravis at the Department of Thoracic and Cardiovascular Surgery, College of Medicine, Korea University. A clinical study that is focused on the factors affecting the operative results was analyzed and the following results were obtained. Among the 20 patients, male to female ratio was 8:12 and the age of onset was ranged from 3 years to 67 years. The chief complaints in order of frequency were as follows; ocular symptoms such as ptosis and diplopia[7 cases], general weakness[4 cases], swallowing difficulty[3 cases], dyspnea[3 cases], dysphasia[1 case], headache[1 case] and dizziness[1 case]. The severity of disease was classified by modified Osserman`s method that Group IIa was 8 cases, Group IIb; 7 cases, Group IIc; 3 cases and Group I; 2 cases. In histopathology of thymus, the most frequent finding was hyperplasia[11 cases] followed by thymoma[4 cases], normal tissue[3 cases] and malignant` thymoma[2 cases]. There were two cases of postoperative complications; one case was wound infection and the other was mediastinitis. One case of malignant thymoma died due to respiratory failure with pulmonary metastasis. There was 16 cases[80%] of improvement after thymectomy as follows; complete remission was 4 cases[20%], marked improvement was 9 cases[45%] and subjective improvement only was 3 cases[15%]. The effect of severity and duration of disease on operative result has statistically significant. The effect of thymus histopathology on operative result was not statistically significant. But there were comparable results between thymoma cases and non-thymoma cases.

Purpose: Alagille syndrome is a complex hereditary disorder that is associated with cardiac, hepatic, skeletal, ocular, and facial abnormalities. Mutations in the Notch signaling pathway, such as in JAG1 and NOTCH2, play a key role in embryonic development. A cardiac or hepatic presentation is a critical factor for determining the prognosis. Methods: We conducted a retrospective study of 41 patients with Alagille syndrome or a JAG1 mutation between 1983 and 2013. Results: The first presentations were jaundice, murmur, cyanosis, and small bowel obstruction at a median age of 1.0 months (range, 0-24 months). The JAG1 mutation was found in 27 of the 28 genetically-tested patients. Cardiovascular anomalies were identified in 36 patients, chronic cholestasis was identified in 34, and liver transplantation was performed in 9. There was no significant correlation between the severity of the liver and cardiac diseases. The most common cardiovascular anomaly was peripheral pulmonary stenosis (83.3%), with 13 patients having significant hemodynamic derangement and 12 undergoing surgical repair. A total bilirubin level of >15 mg/dL with a complex surgical procedure increased the surgical mortality (P=0.022). Eight patients died after a median period of 2.67 years (range, 0.33-15 years). The groups with fetal presentation and with combined severe liver and heart disease had the poorest survival (P<0.001). Conclusion: The group with combined severe liver and heart disease had the poorest survival, and a multidisciplinary approach is necessary to improve the outcome.

This study aimed to explore the clinical, radiological, and pathological characteristics of intraocular cysticercosis due to Taenia solium metacestode infection. Total 8 patients diagnosed with intraocular cysticercosis at the Red Cross Hospital of Yunnan Province, China were examined retrospectively. Patients with clear dioptic media had undergone fundus chromophotography. All patients underwent B ultrasonography of the ocular region (CT) successive scanning of the orbit and cerebral tissues. Parasites were extracted surgically and then examined pathologically. The fundus chromophotography showed a white and condensing scolex package in the vesicle. The B ultrasonic examination showed a vesicle-like echogenic mass in the vitreous chamber, in which the high-level echo spot was the cysticercus scolex. The pathological examinations showed that the vesicle wall exhibited hyaline degeneration, inflammatory cell infiltration, neuroglial fiber, and glial cell proliferation layers from the inside to the outside. The scolex is round and is composed of the outer tissue (the body wall) and the inner furrow tissue; these tissues migrated together. Primordially differentiated sucking discs were found in one case, but no hooklets were found. The inner scolex tissue was folded like a paper flower. The severity of intraocular disease is closely correlated with the pathophysiological processes of the cysticercus worm. Pathological examination of the intraocular lesions can help to evaluate the course of the disease as well as to provide a scientific basis for effective antiparasitic medication.

Purpose: Alport syndrome (AS) is one of the most common inherited renal diseases caused due to mutations of genes encoding specific proteins of the type IV collagen family, and its major clinical manifestations include progressive renal failure, sensorineural deafness, and ocular abnormalities. We investigated the clinical characteristics and long-term prognosis of AS in Korean pediatric and adult populations. Methods: We conducted a retrospective review of medical records of 33 children and adults who had been diagnosed or treated with AS from 1985 to 2019. Results: The mean age of the 33 patients diagnosed with AS was 16.2±13.6 years, and the male-to-female ratio was 2:1. At the first visit, recurrent gross hematuria was the most common initial symptom. In 10 of 33 patients (30.3%), sensorineural hearing loss (SNHL) was diagnosed, but none had ophthalmic problems. Moreover, 11 of 33 patients (33.3%) had advanced to end-stage renal disease (ESRD), and a significant difference was observed in the age of the patients who progressed to ESRD based on the presence or absence of SNHL (P=0.035). Conclusion: SNHL in AS can be an important prognostic factor for long-term deterioration of renal function. Further investigation is required to confirm the clinical course and the genetic characteristics of AS in Korea through prospective national cohort studies.

Multiple caries in a pediatric patient often requires dental treatment under general anesthesia, especially when the patient is suffering from a systemic disease. The patient was a 6-year-old boy with Marfan syndrome and needed extensive dental treatment. Marfan syndrome is an inherited disorder resulting from mutations in Fibrillin-1 gene. Patients are known to have mainly cardiovascular, ocular, and musculoskeletal problems. Although clinical symptoms of the syndrome are age-realted, thus hindering early diagnosis of the disease in young children, our patient had been confirmed by a gene study at a younger age. Medical history of the patient revealed moderate to severe mitral regurgitation and aortic root dilatation, which required mitral valve replacement surgery with a mechanical valve. As a result, the patient was taking warfarin post-operatively and changes in medication had to be made before the dental treatment. Also, prophyalctic antibiotics had to be given before the treatment for prevention of (to prevent the) infective endocarditis. With careful control of the medications and bleeding tendency, general anesthesia and the treatment were done successfully without any complications.
