Diagnosis and treatment of major reproductive failures were carried out for 836 dairy cows of 12 farms in Kimje area from May 1999 to May 2000. Reproductive failures were classified into four categories: uterine diseases, ovarian diseases, combination of uterine and ovarian diseases, and anestrus with corpus luteum (CL), based on the diagnosis by both rectal palpation and ultrasonography (SA 600, Medison, 5.OMHz transducer). 1. Of 102 cows examined, 15 cows were diagnosed as pregnant. Cows with real reproductive failures were therefore 87 cows and the rate of reproductive failures far all the cows of 12 farms was 10.4% (87/836). 2. Of 57 cows with reproductive failures, the cows with uterine diseases were 33 heads (37.9%), with ovarian diseases: 30 heads (34.5%), with combination form: 16 heads (18.4%), and with anestrus with CL: 8 heads (9.2%). 3. Of 87 cows with reproductive failures, 7 cows were slaughtered and 80 cows were treated by hormone or douche. The cows expressed estrus were 74 cows (92.5%, 74/80 heads) and 56 cows were pregnant (70.0%, 56/80 heads) following treatment. 4. The reproductive failures tended to be increased as the period proceeded from 30 days (2.3%, 2/87 heads) to over 120 days (56.3%, 49/87 heads) after parturition. 5. Associated other diseases to reproductive failures were foot diseases(5 cows), joint diseases (5 heads), urovagina (6 heads), and rectovaginal fistula (2 cows) and the rate of occurrence of associated diseases was 20.7% (18/87 heads). 6. No reproductive record was used in 7 farms of 12 farms and 5 farms had no play ground or not used for the cows. These results indicated that diagnosis fur reproductive failures by rectal palpation along with ultrasonography was more accurate than the conventional rectal palpation and brought better result of treatment for major types of reproductive failures. It was also indicated that non-uses of reproductive record and play ground were also important factors in occurrence of reproductive failures.

Medical records of 48 pet ferrets that underwent adrenalectomy were retrospectively reviewed to investigate the frequency and clinical outcomes of adrenal diseases in pet ferrets. These diseases were most commonly diagnosed in ferrets aged 3 to 5 years and in neutered females (58.3%). Adrenal disease occurred most frequently in the left adrenal gland (72.9%), followed by involvement of both adrenal glands (16.7%) and the right adrenal gland (10.4%). The mean sizes (length * thickness) of the adrenal glands as determined by ultrasonography were 8.96 * 5.08 mm and 12.91 * 8.26 mm for the left and right adrenal glands, respectively. In the ferrets with adrenal disease, alopecia (82.2%) was the main presenting clinical signs in both sexes, and vulvar swelling was seen in 32.1% of the females with adrenal disease. The common incidental findings included renal cysts (29.2%) and splenomegaly (25.0%). Histological findings showed pheochromocytoma, adenoma, and hyperplasia in 44.7%, 14.9%, and 12.8% of cases, respectively. The survival rates at 1- and 2- years after surgery were 87.5% and 74.0%, respectively. Alopecia and vulvar swelling improved within an average of 3.4 months and 12 days after surgery.

Objectives: REM sleep behavior disorder (RBD), characterized by excessive motor activity during REM sleep, is associated with loss of muscle atonia. In recent years, it has been reported that RBD has high co-morbidity with CNS disorders (especially, Parkinson's disease, dementia, multiple system atrophy, etc.). We aimed to assess differences in clinical and polysomnographic findings among RBD patients, depending on the presence or absence of central nervous system (CNS) disorders. Methods: The medical records and polysomnographic data of 81 patients who had been diagnosed as having RBD were reviewed. The patients were classified into two groups: associated RBD (aRBD, i.e., with a clinical history and/or brain MRI evidence of CNS disorder) and idiopathic RBD (iRBD, i.e., without a clinical history and/or brain MRI evidence of CNS disorder) groups. Twenty-one patients (25.9%) belonged to the aRBD group and 60 patients (74.1%) belonged to the iRBD group. The clinical characteristics and polysomnographic findings of the two groups were compared. Results: Periodic limb movement disorder (PLMD), i.e., PLMI (periodic limb movement index)>5, was observed more frequently in the aRBD group than in the iRBD group (p<0.001, Fisher's exact test). Also, obstructive sleep apnea syndrome (OSAS), i.e., RDI (respiratory disturbance index)>5, was found more frequently in the aRBD group (p=0.0042, Fisher's exact test). The percentages for slow wave sleep and sleep efficiency were significantly lower in the aRBD group than in the iRBD group. Conclusion: We found that 1 out of 4 RBD patients had associated CNS disorders, warranting more careful neurological evaluation and follow-up in this category of RBD. In this category of RBD patients, we also found more frequent PLMD and OSAS. These patients were also found to have lower slow wave sleep and sleep efficiency. In summary, RBD patients with associated CNS disorders suffer from more disturbed sleep than those without them.

Objectives: Periodic limb movements in sleep(PLMS) is a moderately prevalent disorder, of which pathophysiology remains largely unknown. PLMS has been reported to be common in patients with obstructive sleep apnea syndrome(OSAS), but reports on their relationship have been inconsistent in previous studies. Inconsistency of results may be attributable to insufficient number of the study subjects. We attempted to explore the influence of OSAS on PLMS in a large number of subjects. Methods: Three hundred and twenty subjects(M : F=192:128) with PLMS, as identified by the nocturnal polysomnography, were studied. Sample mean age was 53.1(SD=15.1) years and their mean periodic limb movement index(PLMI) is 25.2/hr (SD=24.8). PLMS subjects were divided into two groups, based on the presence or absence of OSAS. Periodic limb movement indices and sleep parameters between two groups were analyzed to evaluate the effects of OSAS on PLMS. Results: Each of PLMI and PLMI with arousal(PLMAI) correlated positively with age. PLMI of men was larger than that of women (p<0.01). The presence of comorbid OSAS independently had influence on PLMI(t=-2.20, p<0.05), but not PLMAI. There were no significant differences between the two groups in their PLMI, PLMAI and sleep parameters. However, the two groups differed in PLMI-correlated sleep parameters. In PLMS subjects with comorbid OSAS, PLMI was negatively correlated with each of slow wave sleep time and REM sleep time. In subjects without comorbid OSAS, PLMI was negatively correlated with sleep efficiency. Conclusion: PLMS patients with OSAS turned out to have increased PLMI than those without OSAS We suggest that OSAS patients may have subtle autonomic arousals and these arousals could, in part, express themselves as PLM.

A male infant was diagnosed with obstetric brachial plexus injury, congenital muscular torticollis and cleft palate 17 days after birth. His mother presented with gestational diabetes and premature rupture of membranes. Although it is possible that these three disorders arose independently, it is very likely that all three have the same etiologic cause, and we propose that a possible mechanism for this concurrence is related to maternal gestational diabetes. Maternal hyperglycemia mostly affects fetal structures deriving from the neural crest, including the palatine bone, and may have caused the cleft palate observed in this case. Gestational diabetes is also associated with increased frequency of large for gestational age infants and, by extension, with increased risk of birth injuries such as obstetric brachial plexus injury or congenital muscular torticollis associated with large for gestational age infants. Since the children of mothers with gestational diabetes are at increased risk for congenital defects such as cleft palate as well as being large for gestational age, precautions indicated for each respective disorder must be taken during prenatal testing and during birth. However, further studies of more cases are required to evaluate whether the concurrence of obstetric brachial plexus injury, congenital muscular torticollis and cleft palate in this case are complications specifically associated with gestational diabetes or just a simple coincidence.

Septic encephalopathy is defined as brain dysfunction secondary to sepsis. It occurs in septic patients as a manifestation of multi-organ dysfunction. Without evidence of intracranial infection, various extracranial infections causing severe sepsis may induce septic encephalopathy. We report a patient with septic encephalopathy complicating acute appendicitis. Initially, the patient presented with impaired mental state and raised liver enzymes.

Pheochromocytoma is a rare tumor of childhood, arising from adrenal medullary and chromaffin tissue. Because chronic hypoxia may induce pheochromocytoma, there have been several reports of pheochromocytoma development in cyanotic patients after corrective or palliative cardiac surgery. The variable clinical presentation of pheochromocytoma is obscured by both underlying heart disease and medications. If sudden hypertension, aggravation of a heart condition, or unusual symptoms such as diabetes mellitus develops in a cyanotic patient with congenital heart disease, pheochromocytoma must be ruled out. We report two patients presenting with cyanotic single-ventricle heart disease with pheochromocytoma.

Chiari type 1 malformation is a developmental condition characterized by cerebellar herniation and syringohydromyelia in human beings. It has been reported as a common condition in the cavalier King Charles spaniel that is similar to human Chiari type 1 malformations. However, there are few documentations of diagnosed Chiari type 1 like malformation in other breed dogs. Abnormalities compatible with such a malformation were identified by magnetic resonance imaging in 24 dogs with neurologic signs in this study. The dogs were 15 females and 9 males. Their breed were variable, and 6 of the dogs were maltese, 5 were shih-tzu. The dogs had a variety of neurological signs and the severity of cerebellar herniation, syringohydromyelia, intracranial intra-arachnoid cyst or hydrocephalus.
