A miniature schnauzer (8 years old, male castrated), diagnosed as diabetes mellitus 6 months ahead, were referred to the Veterinary Medical Teaching Hospital of our University with hindlimb stiffness, facial rubbing and tetany. Serum chemistry showed severe hypocalcemia, hypomagnesemia, and measured iPTH (intact pharathyroid hormone) concentration was low (< 3.0 pmol/L). Consistent rate injection of calcium gluconate (282 mg/kg over 30 min) resulted in prompt relief of the tetany. Then typical treatment for hypoparathyroidism (calcium gluconate and dihydrotachysterol per os) with magnesium administration could control the neuromuscular signs. Diabetes mellitus is being controlled by insulin therapy and prescription diet. Hypomagnesemia in diabetic dog may be induced hypoparathyrodism.

In the early neonatal period, the neonate is challenged by the loss of the placental calcium transport and manifests a quick transition, from an environment in which PTHrP plays an important role to a PTH- and 1,25-dihydroxyvitamin D-controlled neonatal milieu. Disturbances in mineral homeostasis are common in the neonatal period, especially in premature infants and infants who are hospitalized in an intensive care unit. In many cases these disturbances are thought to be exaggerated responses to the normal physiological transition from the intrauterine environment to neonatal independence. Some disturbances in calcium and phosphate homeostasis are the result of genetic defects, which in many instances can now be identified at the molecular level. Although fetus develop remarkably normally in the presence of maternal calcium, PTH and vitamin D deficiency, the neonates demonstrate abnormalities that are consequences of the prior abnormal maternal calcium homeostasis. Evaluation and management of hypocalcemia and hypercalcemia in neonate requires specific knowledge of perinatal mineral physiology and the unique clinical and biochemical features of newborn mineral metabolism.

Experimental hypocalcemia was induced in normal goats by intravenous infusion with various concentration of $Na_2$-EDTA solution. 1. Progressive depression of reflexes and body temperature, paresis, and cardiac arrest were observed in two groups infused with 4% and 8% EDTA solution, whereas paresis and cardiac arrest were not observed in 3% EDTA group. 2. The patterns of electrocardiogram were changed according to the decrease of plasma Ca level in all of 7 goats. When plasma Ca decreased to 6mg per 100ml or below, sinus bradycardia or tachycardia and prolongation of QT interval were showed, while atrioventricular block was noted in case which the plasma Ca level decreased to 4mg per 100ml or below. Fibrillation and cardiac arrest were evident in case which the plasma Ca level decreased to as low as 3mg per 100ml.

1세, 암컷, 17 kg의 잡종견이 갑작스러운 허탈증상으로 본원에 내원하였다. 혈액 검사 결과에서 심각한 저칼슘혈증을 보였으며, 방사선 사진 영상에서는 장 폐색을 의심하게 하는 가스로 가득 찬 장확장증 소견을 나타내었다. 칼슘 글루코네이트의 정맥 내 투여를 시작한 후 4시간째에 장 확장 소견은 경감되었다. 혈청 부갑상샘호르몬 농도는 저칼슘혈증에 비해 정상 범위 아래로 측정되었으며, 이를 기초로 하여 환견은 일차성 부갑상샘기능저하증으로 진단되었다. 칼슘 글로코네이트와 칼시트리올의 투여 3일 후, 환견의 임상증상과 전해질 불균형은 개선되었다. 본 보에서는 일차성 부갑상샘기능저하증으로 진단된 개에서 일반적으로 관찰되지 않는 증상인 심각한 위장관 확장증의 발생 예를 보고한다.

CHARGE syndrome (coloboma, heart defects, atresia choanae, retarded growth and development, genital hypoplasia, and ear abnormalities) is characterized by multiple malformations and is diagnosed using distinct consensus criteria. Mutations in the gene encoding chromodomain helicase DNA-binding protein 7 (CHD7) are the major cause of CHARGE syndrome. Clinical features of CHARGE syndrome considerably overlap those of 22q11.2 deletion syndrome. Of these features, immunodeficiency and hypocalcemia are frequently reported in patients with 22q11.2 deletion syndrome but are rarely reported in patients with CHARGE syndrome. In this report, we have described the case of a patient with typical phenotypes of 22q11.2 deletion syndrome but without the proven chromosome microdeletion. Mutation analysis of CHD7 identified a pathogenic mutation (c.2238+1G>A) in this patient. To our knowledge, this is the first case of CHARGE syndrome with immunodeficiency and hypocalcemia in Korea. Our observations suggest that mutation analysis of CHD7 should be performed for patients showing the typical phenotypes of 22q11.2 deletion syndrome but lacking the proven chromosome microdeletion.

PTH 측정은 체내 칼슘 및 이온화 칼슘의 수치와 함께 갑상선 절제술 후 저칼슘혈증을 예측하는 유용한 지표로서 임상에서는 신속한 결과 보고를 요구하고 있으나 검사반응시간이 길어 이에 상응하지 못하고 있다. 따라서 본 연구는 PTH 검사반응시간에 변화를 주어 신속한 결과 보고를 함으로서, 저칼슘혈증 예측 지표의 유용성을 평가하고자 한다. 2009년 7~8월까지 PTH를 검사한 환자들(n=131)을 대상으로 하였으며, 검사방법은 면역방사계수법으로 반응시간은 18${\pm}$2시간(Overnight), 0.5, 3, 6시간으로 구분하여 상관관계, 정밀도(10회 반복), 회수율을 측정하였다. 또한 조기 저칼슘 혈증 예측지표의 유용성을 평가하기 위해 민감도, 특이도, 양성예측도, 정확도를 비교 분석 하였다. 상관관계에서는 overnight을 기준으로 0.5시간은 $R^2$=0.987, 3시간은 $R^2$=0.993, 6시간은 $R^2$=0.996로 나타났다. 정밀도(%CV${\pm}$SD)에서 0.5시간은 $15.92{\pm}15.54$, 3시간은 $6.91{\pm}7.38$, 6시간은 $4.30{\pm}4.69$, Overnight은 $4.59{\pm}2.59$로 측정되었다. 회수율(%Mean${\pm}$SD)에서 0.5시간은 $96.8{\pm}5.44$, 3시간은 $102.6{\pm}4.35$, 6시간은 $100.7{\pm}2.56$, Overnight은 $102.2{\pm}5.98$로 측정되었다. 양성 예측치(cut-off point=15 pg/mL)를 기준으로 저칼슘혈증을 예측할 때, 0.5시간일 때 민감도 97.5% 특이도 96.0% 양성예측도 86.6% 정확도 84.7%였고, 3시간일 때 민감도 97.5% 특이도 100% 양성예측도 100% 정확도 97.5%였고, 6시간일때 민감도 97.5% 특이도 92.3% 양성예측도 92.8% 정확도 90.6%였다. Overnight법과 비교할 때 검사반응시간 3시간에서 98.3%로 가장 높은 일치율을 보였고, Kappa와 상관관계 또한 우수하였다. 이에 검사반응시간을 3시간으로 단축시켜 신속한 결과를 보고함으로써 환자의 저칼슘혈증을 조기에 예측하여 칼슘제 투여 등 적절한 조치를 취하여 환자의 증상발현을 막을 수 있는 유용한 지표로 활용될 것이다.

Papillary thyroid carcinoma has a good prognosis, but the frequency of locoregional lymph node metastasis is high and is known to occur stepwise fashion. Prophylactic central node dissection in papillary thyroid carcinoma is widely performed from the past. But, the pros and cons of the prophylactic central node dissection has been ongoing for a long time. In the American Thyroid Association management guideline for thyroid nodules and differentiated thyroid cancer, which is the most widely used, recommendations about prophylactic central node dissection has been changed in past ten years. In recent systematic review and meta-analysis, prophylactic central node dissection increases the rate of transient hypocalcemia and recurrent laryngeal nerve injury, but there is no difference in the frequency of permanent hypocalcemia or recurrent laryngeal nerve injury. Prophylactic central node dissection has not been shown to improve patient survival, but recurrence has been reported to decrease. According to a questionnaire survey of the members of Korean Scociety of Thyroid-Head and Neck Surgery, Korean doctors tend to perform the prophylactic central node dissection more aggressively than other countries. The reason for this is that Korea has a large number of thyroid surgeries and therefore surgeons are more experienced than other countries.

Hydrofluoric acid (HF), one of the strongest inorganic acids, is used mainly for industrial purpose. Hydrofluoric acid injuries has a potential for both systemic as well as severe local tissue destruction. One of the most serious consequences of severe exposure to HF by any route is marked lowering of serum calcium (hypocalcemia) and other metabolic changes, such as hypomagnesemia and which may result in a fatal outcome if not recognized and treated. promptly cardiotoxicity is not well known except arrhythmias, which are a primary cause of death. We report a case of myopericarditis by ingestion of hydrofluoric acid.
