저자들은 하시모토 갑상선염 환자에서 갑상선 유두암과 여포암이 동반되어 발생한 드문 예를 경험하여 보고하는 바이며 하시모토 갑상선염 환자에서 갑상선 결절에 대한 적절한 추적과 감시가 갑상선 암의 조기 발견과 치료에 도움이 될 수 있을 것으로 생각한다. We report here on a rare case of papillary and follicular carcinoma of the thyroid gland that developed in a 31 years old woman who was previously diagnosed with Hashimoto`s thyroiditis. Her chief complaint was a palpable neck mass. The antimicrosomal and antithyroglobulin antibody levels were elevated. Ultrasonography of the left thyroid gland revealed a 2.5×2.0 cm sized thyroid nodule. Fine needle aspiration biopsy of the thyroid nodule was done and this was diagnosed as Hashimoto`s thyroiditis. There was no evidence of thyroid cancer. After 1 year, thyroid ultrasonography and biopsy were repeated for examining an enlarged thyroid nodule. Total thyroidectomy was then performed. The histopathologic examination revealed that the right and left thyroid glands were in accordance with the diagnosis of papillary and follicular cancer, respectively. Until now, no known case of simultaneous papillary and follicular carcinoma in Hashimoto`s thyroiditis has been reported. This case suggests that adequate follow up for Hashimoto`s thyroiditis patients with thyroid nodule may help the early detection and management of thyroid cancer. (Korean J Med 72:558-562, 2007)

The time-varying characteristics of infinite data streams require continuous queries to be adaptively processed. The order in which multiple join operations are evaluated has serious consequences for the algorithm performance because the selectivity of each join operation can differ significantly from the selectivity of the other operations. The evaluation order may be effectively determined using the k-EGA and A-SEGO schemes, as proposed in previous studies. These methods optimize target continuous queries by monitoring a set of their promising subplans simultaneously. Each scheme also employs a user-defined cost-bound parameter for controlling the number of monitored subplans. A more optimized global plan may be generated by using a more highly configured cost-bound parameter. However, this approach can increase the overhead associated with monitoring the subplans. This paper proposes a new scheme, Adaptive Run-time Overhead Adjustment (AROA), which provides a novel method for adaptively determining the value of a cost-bound parameter based on the system environment. Unlike the previously described A-SEGO scheme, the scheme proposed here automatically selects the cost-bound parameter to reflect the system workloads (e.g., the input tuple rate, and other parameters). This method not only augments the probability of generating an optimized execution plan, it reduces the run-time delay caused by the optimization process. Experimental verification of the proposed scheme AROA demonstrated that AROA outperforms the previous schemes.

A hepatoblastoma is the most common liver tumor in children between 6 months to 3 years of age. It is a rare malignancy of the liver with an incidence of 0.7 to 1 case per 1 million children under 15 years of age in Western countries. Males are more affected. Patients usually have normal liver funtion test, but have high serum levels of alpha-fetoprotein(AFP), which is a sensitive diagnostic marker. They usually present with abdominal distension or an asymptomatic abdorninal mass. Rarely, patients with a hepatoblastoma show an acute abdominal emergency which is not typical for the disease process. The management of a ruptured hepatocellular carcinoma provides guidance for diagnosis and treatment of a hepatoblastoma because the incidence of hepatoblastoma is low. We report a child who presented abdominal pain and distension with the diagnosis of a ruptured hepatoblastoma.

Acute renal infarction is an uncommon disease which is often delayed or missed due to its rarity and unspecific clinical presentations. Most patients have an underlying disease or embolic event that can be detected easily by history and physical examination. The frequently noted symptoms include flank, abdominal, and back pain, as well as nausea. The pain is usually acute, severe, and sharp in nature without radiation. The most sensitive laboratory test is lactate dehydrogenase. Angiography, renal scintigraphy, IVP (intravenous pyelography), sonography and, CT (computed tomography) can be used in diagnosing renal infarction. However, CT is more preferred for the diagnosis of renal infarction because it has the advantages of easy accessability and noninvasiveness. Once diagnosed, conservative treatment with intra-arterial infusion of thrombolytics or heparin appears to be the most favorable modality. We report a 82-year-old male with asynchronous bilateral renal infarctions associated with atrial fibrillation and coronary artery disease. His clinical status improved during admission without any events.

N/A Objectives: The 12-s maximum voluntary ventilation(MVV) provides an estimate of the ventilatory reserves available to meet the physiologic demands of exercise. Earlier studies established a correlation between MVV and forced expiratory volume in one second(FEV1). We hypothesized that the resting maximum inspiratory flow rate(MIFR) may be a determinant of MVV and evaluated MIFR as a predictor varialbe for MVV and also examined some other formulas for calculation of indirect MVV. Methods: Between December 1992 and May 1993, a total of 111 subjects, 85men and 26 women(age 53±5 yr, mean±SD), with expiratory impairment categories of severe(n=22), moderate(n=20), mild(n=17) in patients with chronic obstructive pulmonary disease(COPD) and control (n=52) based on FEV1(percentage of predicted), enrolled the study samples. We measured FEV, MIFR and MVV by body plethysmograph in all subjects and examined the relation between FEV1 and MVV, MIFR and MVV and calculated indirect MVV using the stepwise method of forward multipul linear regression. I present r2 values, coefficients of determination, as measures of linear association for regression relationships. Results: 1) The MIFR correlated with MVV in normal control(p<0.05, r2-0.681) and patients with COPD (p<0.05, r2=0.682) better than FEV. 2) MIFR joined with FEV in multiple linear regression to significantly improve the description of MVV: normal control MVV(L/min) = 20,58FEV1 (L) + 7.11MIFR(L/s) + 49.90(n=52; p<0.05, r2= 0.8735), patients with COPD MVV(L/min) = 36.64FEV1(L) + 4.64MlFR(L/s) - 7.21(n=59; p<0.05, r2=0.7173). Conclusion: MIFR is a significant determinant of MVV in normal control and patients with COPD and also contributes to improuenent in accuracy of indirect estimates of MVV.

저자들은 말초 혈액에서 현저한 호산구 증가를 보이면서 간, 임파선, 골수 및 폐에 호산구 침윤을 보여 hydroxyurea로 치료한 특발성 과호산구 증후군 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. The idiopathic hyperecoinophilic syndrome consists of peripheral blood eosinophilia of 1500/㎣ or more without a known cause, plus signs and symptoms of organ eosinophilia. The prognosis of HES without treatment is poor. However, about one third of the patients with this syndrome may respond to corticosteroid thrapy. Morever, the majority of the remainder may have a favorable response to hydroxyurea. We present here a case of hypereosinophilic syndrome without any identifiable causes, involving bone marrow, liver, lungs and cervical lymph node. We tried corticosteroid as a treatment but it showed on response. However the hydroxyurea showed good response.
