Ectopic thyroid tissue is a rare entity and thyroid papillary carcinoma arising in branchial cleft cyst is extremely rare. We report a interesting case of thyroid papillary carcinoma lying within a branchial cleft cyst. A 49-year-old man presented with a 2-month history of a lateral neck mass. Thyroid ultrasonography showed a cystic mass with some portion of solid papillary projection. Fine needle aspiration of the cyst showed few cellular debris without any identifiable tumor cell. But thyroglobulin level in the cyst fine needle aspiration specimen was 283 ng/ml. The cyst was excised and the frozen section revealed thyroid papillary carcinoma. Thus, a total thyroidectomy with anterior neck dissection was performed. Histopathology revealed that papillary carcinoma was limited to thyroid tissue, which was in turn located within a branchial cleft cyst. The specimens include thyroid gland and lymph nodes were extensively examed, however no evidence of an occult papillary carcinoma was identified. To our knowledge, this is the first reported case of a thyroid carcinoma arising in ectopic thyroid tissue within branchial cleft cyst in Korea. When a neck cyst is diagnosed by clinical examination, thyroid papillary carcinoma should be considered as part of the differential diagnosis.

제 2형 당뇨병 환자에서 인슐린 글라진 시작 시 병용 약제에 따른 혈당 변화 양상 비교

서론: 당뇨병에서 식후 혈당이 심혈관계질환의 독립적인 위험인자로 규명되면서 식후 혈당의 중요성이 점차로 부각되고 있다. 본 연구에서는 기저 인슐린인 인슐린 글라진 투여 시작 시 식후 혈당 강하 효과가 큰 두 약제를 병용하는 경우와 공복 혈당 강하 효과가 큰 두 약제를 병용하는 경우를 비교하고자 하였다. 방법: 2005년 1월부터 2008년 7월까지 세브란스병원 당뇨병센터를 방문한 제2형 당뇨병 환자 중 인슐린 글라진 시작 시 메글리 티니드계열 약제와 알파글루코시다제억제제를 병용한 환자 75명(A군)과 설폰요소제와 메트포민을 병용한 환자 53명(B군)을 대상으로 3개월 후 혈당 변화 양상을 비교하였다. 인슐린 글라진의 사용량은 자가혈당 측정을 통해 환자 스스로 조절할 수 있도록 하였다. 결과: A군과 B군의 평균 나이는 각 66.3±12.5세와 60.2±14.3세(Δ=6.1세, p=0.01)였으며, 평균 당뇨 유병 기간은 각 8.4±4.6년, 7.2±2.8년(Δ=1.2년, p=0.20)이었다. A군과 B군의 치료 전 공복혈당(각 193±73 mg/dL, 202±67 mg/dL), 식후2시간혈당(각 313±92 mg/dL, 320±93 mg/dL), 당화혈색소(각 9.7±1.4%, 9.7±1.4%) 간 통계적으로 유의한 차이는 없었다. 치료 3개월 후 공복혈당은 각 116±35 mg/dL, 128±37 mg/dL(Δ=11.3 mg/dL, p=0.09), 식후2시간혈당은 각 209±68 mg/dL, 255±66 mg/dL(Δ=46.1 mg/dL, p=0.00), 당화혈색소는 각 8.0±1.1%, 8.5±1.0%(Δ=0.48%, p=0.02)이었다. 결론: 인슐린 글라진 투여 시작 시 설폰요소제 와 메트포민을 병용하는 경우에 비하여 메글리티니드 계열 약제와 알파글루코시다제억제제를 병용하는 경우가 당화혈색소 개선과 함께 특히 식후2 시간 혈당 개선에 도움이 될 것으로 사료된다.
