Purpose: We compared thyroid hormone profiles in children with nephrotic syndrome (NS) during the nephrotic phase and after remission. Methods: This study included 31 pediatric NS patients. The thyroid hormone profiles included serum levels of triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH), and free T4. Results: Of the 31 patients, 16 (51.6%) showed abnormal thyroid hormone profiles: 6 had overt hypothyroidism, 8 had subclinical hypothyroidism, and 2 had low T3 syndrome. The mean serum T3, T4, and free T4 levels in the nephrotic phase and after remission were $82.37{\pm}23.64$ and $117.88{\pm}29.49ng/dL$, $5.47{\pm}1.14$ and $7.91{\pm}1.56{\mu}g/dL$, and $1.02{\pm}0.26$ and $1.38{\pm}0.23ng/dL$, respectively; the levels were significantly lower in the NS nephrotic phase (P=0.0007, P<0.0001, and P=0.0002). The mean serum TSH levels during the nephrotic phase and after remission were $8.05{\pm}3.53$ and $4.08{\pm}2.05{\mu}IU/mL$, respectively; they were significantly higher in the nephrotic phase (P=0.0005). The urinary protein/creatinine ratio during the nephrotic phase was significantly correlated with serum T3, T4, and free T4 levels (r=-0.5995, P=0.0032; r=-0.5797, P=0.0047; r=-0.5513, P=0.0078) as well as with TSH levels (r=0.5022, P=0.0172). A significant correlation was found between serum albumin and serum T3 levels during the nephrotic phase (r=0.5385, P=0.0018) but not between serum albumin and T4, TSH, or free T4 levels. These significant correlations all disappeared after remission. Conclusion: Abnormal thyroid hormone profile findings were observed in 51.6% of pediatric patients with NS. Thyroid hormone levels normalized after remission, regardless of levothyroxine therapy.

목 적 : 천식 환자에서 특징적으로 존재하는 BHR의 기전으로 호산구성 기도 염증 반응이 중요시 생각되고 있다. 그러나 장기간 천식 관해 상태인 청소년에서 BHR이 지속되는 기전에 대해서는 아직 명확하지 않은 실정이다. 본 연구는 장기간 천식 관해 된 청소년에서의 BHR이 호산구성 기도 혈액내 총 호산구 증가와 혈청 ECP 농도의 증가와 연관되어 있는지 알아보고자 시행하였다. 방 법 : 서울대학교 어린이병원 소아과 외래에서 아토피성 천식으로 진단되었던 청소년 중 임상적으로 장기간 관해(최근 2년간 천식 증상이 없고 치료가 필요 없었던 경우)되었으나 BHR이 잔존하는 35명과 이들과 서로 대응하는 BHR을 갖고 있으면서 현증을 보이는 아토피 천식 청소년 35명을 대상으로 하였다. 이 두 군간의 총 호산구 수와 혈청 ECP 농도를 비교하고 각 군에서 총 호산구 수 및 혈청 ECP 농도와 $PC_{20}$ 사이에 상관 관계가 있는 지 분석하였다. 결 과 : 장기간 관해 된 군의 혈액 내 호산구 수와 혈청 ECP 농도의 평균값이 현증을 보이는 군보다 통계적으로 유의하게 낮았다($273{\pm}108$ vs. $365{\pm}178/{\mu}L$; $16.3{\pm}9.4$ vs. $26.5{\pm}15.1{\mu}g/L$, both, P<0.05). 현증을 보이는 군에서는 메타콜린 $PC_{20}$에 따라 혈액 내 호산구 수 및 혈청 ECP 농도가 각각 통계적으로 유의한 음의 상관관계를 보였으나(r=-0.385, P=0.022; r=-0.439, P=0.008) 장기간 관해 된 군에서는 유의한 상관관계를 보이지 않았다(r=-0.292, P=0.089; r=-0.243, P=0.159). 결 론 : 이와 같은 소견은 장기간 관해시의 BHR은 호산구성 염증과 연관성이 없으며 현증 천식에서의 BHR과는 다른 기전으로 설명될 수 있을 것으로 추정된다. 장기간 천식 관해 된 청소년에서 BHR이 잔존하는 기전에 대하여 정확히 밝히기 위해서 향후 BAL, 조직 검사, 유도 객담 등을 이용한 연구를 시행할 필요가 있다.

Leukemia in pregnancy was first reported by Virchow in 1845, and acute Leukemia that occurs with pregnancy is extremely rare. About 350 pregnancies with leukemia have been reported in literature. The incident of acute leukemia during pregnancy has been reported in one case per 100,000 pregnancies case. A 40-year-old patient with 30 weeks of pregnancy, (by promyelocyte which is contained granules and auer rods in the bone marrow and biopsy) was diagnosed with acute promyelocyte leukemia WITH t (15;17) (q22;q12); PML-RARA. (M3) in peripheral blood and bone marrow examination, and gave a birth to the fetus normally, January 24, 2013, after receiving the complete remission decision from the bone marrow, complete blood cell count, PML-RARA PCR test, showed normal findings until March 2013. The treatment of acute leukemia during pregnancy should be considered as treatment of a pregnant mother and the impact on the fetus. Decisions about when and how birth takes place is difficult and has to consider both mother and fetus. It is preferable to start immediate treatment without delay so that the treatment time to achieve complete remission or full recovery of the pregnant mother is longer.

목 적 : 본 연구에서는 현증 천식 환자의 BHR에는 기도 염증이 중요한 요인으로 작용하기 때문에 ${\beta}_2$-아드레날린 수용체 유전자와의 연관성이 나타나지 않지만, 청소년기 천식 관해 상태에서 지속되는 BHR에는 상대적으로 유전적인 영향이 강하기 때문에 ${\beta}_2$-아드레날린 수용체 유전자와의 연관성이 나타날 것이라는 가설을 세우고, 이를 검증해 보고자 하였다. 방 법 : 장기간 천식 관해 상태(최근 2년간 천식 증상이 없고 치료가 필요 없었던 경우)에서 BHR이 지속되는 청소년 202명(천식 관해군), 현증 천식 청소년 182명(현증 천식군), 정상군 200명을 대상으로, 메타콜린 기관지 유발검사와 피부단자시험을 시행하였으며 혈청 총 IgE를 측정하였다. ${\beta}_2$-아드레날린 수용체 유전자의 일배체형 분석을 위해 아미노산 16번과 27번을 포함하고 있는 ${\beta}_2$-아드레날린 수용체 유전자 부위를 polymerase chain reaction(PCR)으로 증폭한 뒤, 16번 유전형은 allele specific PCR, 27번 유전형은 PCR-restriction fragment length polymorphism (RFLP) 방법으로 분석하였다. 결 과 : Gly 동형접합자(homozygote)의 빈도는 정상군에서 14.5%, 현증 천식군에서 18.1%, 천식 관해군에서 24.2%로 증가하는 경향이 관찰되었으며(P=0.01), 현증 천식군과 정상군 사이에서는 차이가 없었지만 천식 관해군과 정상군 사이에서는 유의한 차이가 관찰되었다(P=0.01). Gly16-Gln27 일배체형 빈도는 정상군에서 36.5%, 현증 천식군에서 40.4%, 천식 관해군에서 44.6%로 증가하는 경향이 관찰되었으며(P=0.02), 현증 천식군과 정상군 사이에서는 차이가 없었지만 천식 관해군과 정상군 사이에서는 유의한 차이가 관찰되었다(P=0.02). 천식 관해군에서 Gly16-Gln27 일배체형의 수가 증가함에 따라 $PC_{20}$ 기하 평균값이 유의한 차이를 보임으로써(P=0.02) Gly16-Gln27 일배체형과 $PC_{20}$ 사이의 연관성이 관찰되었으나 현증 천식군에서는 이러한 연관성이 관찰되지 않았다. 결 론 : ${\beta}_2$-아드레날린 수용체 유전자가 BHR을 유발하는 유전자적 배경을 가지면서 천식 질병을 조절하는 역할을 하고 있음을 시사한다.

Graves disease (GD) is the most common cause of hyperthyroidism, accounting for more than 90% of cases in Korea. Patients with GD are treated with any of the following: antithyroid drugs (ATDs), radioactive iodine (RAI) therapy, or thyroidectomy. Most patients begin treatment with ATDs, and clinical guidelines suggest that the appropriate treatment period is 12 to 18 months. While RAI treatment and surgery manage thyrotoxicosis by destroying or removing thyroid tissue, ATDs control thyrotoxicosis by inhibiting thyroid hormone synthesis and preserving the thyroid gland. Although ATDs efficiently control thyrotoxicosis symptoms, they do not correct the main etiology of GD; therefore, frequent relapses can follow. Recently, a large amount of data has been collected on long-term ATDs for GD, and low-dose methimazole (MMZ) is expected to be a good option for remission. For the long-term management of recurrent GD, it is important to induce remission by evaluating the patient's drug response, stopping ATDs at an appropriate time, and actively switching to surgery or RAI therapy, if indicated. Continuing drug treatment for an extended time is now encouraged in patients with a high possibility of remission with low-dose MMZ. It is also important to pay attention to the quality of life of the patients. This review aimed to summarize the appropriate treatment methods and timing of treatment transition in patients who relapsed several times while receiving treatment for GD.

Purpose: To improve professional intensive care by analyzing admission causes, causes of death, disease conditions, and treatment processes in patients with hematological malignancies admitted to intensive care units (ICUs) in South Korea. Methods: This was a retrospective study approved by IRB, and conducted on admission with 559 adults, in the hematology ICU of a hospital located in Seoul. The study was carried out from April 2009 to March 2012. Data were analyzed using SAS. Results: Pneumonia was the most frequent cause of ICU admission and death, followed by sepsis. The condition at discharge was death (53.6%), recovery (39.9%), or hopeless (5.1%). Mortality of patients in states of incomplete remission was higher than that of patients with complete remission and of patients with multiple myeloma, severe aplastic anemia, and lymphoma. Conclusion: Results show that pneumonia and sepsis are the most frequent causes of ICU admission and for the death of patients with hematological malignancies. The most frequent status at discharge of patients with hematological malignancies was death (53.6%), with mortality of patients at Incomplete Remission status, of mechanically ventilated patients, and of patients on continuous renal replacement therapy (CRRT) being higher than others.

Purpose: The question of surgical versus non-surgical treatment for diabetic foot osteomyelitis remains subject to debate. The aims of this study were to analyse the outcome of conservative treatment (antibiotic treatment and conservative surgery) for diabetic foot osteomyelitis and identify the predictive factors of remission in conservative treatment of diabetic foot osteomyelitis. Materials and Methods: Seventy-seven patients with diabetic foot osteomyelitis who initially received conservative treatment from January 2004 to July 2013 were identified, and their medical records were reviewed. Diabetic foot osteomyelitis was defined by imaging studies or histological evidence. Remission was defined as the absence of any sign of infection at the initial or contiguous site assessed at least 12 months after the end of treatment. The demographic, clinical, and therapeutic factors were analysed. Results: The mean age of the patients was $62.7{\pm}12.2$ years, and 47 patients (61.0%) were male. The median diabetes duration was $15.7{\pm}11.2$ years and mean HbA1c was $8.7%{\pm}2.4%$. Forty-eight patients (62.3%) healed with conservative treatment (antibiotic treatment and conservative surgery). Twenty-five patients (32.5%) underwent amputation. In the multivariate analysis, concomitant peripheral artery disease and inadequate antibiotic therapy were associated with failure of conservative treatment. Conclusion: Antibiotics alone, or with conservative surgery, were successful in treatment of diabetic foot osteomyelitis in 62.3% of the patients. Concomitant peripheral artery disease and inadequate antimicrobial therapy were risk factors for remission in conservatively treated diabetic foot osteomyelitis.

Purpose : This study was aimed to determine the predictive risk factors for the treatment response and relapse rate in children diagnosed with idiopathic nephrotic syndrome. Methods : We analyzed the medical records of children who were diagnosed and treated for childhood idiopathic nephrotic syndrome from November 1991 to May 2005. Variables selected in this study were age at onset, sex, laboratory data, concomitant bacterial infections, days to remission, and interval to first relapse. Results : There were 46 males and 11 females, giving a male:female ratio of 4.2:1. The age($mean{\pm}SD$) of patients was $5.8{\pm}4.1$ years old. Of all patients who were initially given corticosteroids, complete remission(CR) was observed in 54(94.7%). Of the 54 patients who showed CR with initial treatment, 40(70.2%) showed CR within 2 weeks and 14(24.6%) showed CR after 2 weeks. The levels of serum IgG were lower in the latter group who showed CR after 2 weeks(P=0.036). Of the 54 patients who showed CR with initial treatment, 47(82.5%) relapsed. Of these patients, 35.1% were frequent relapsers and 43.9% were infrequent relapsers. There was no significant correlation between the frequency of relapse and the following variables : sex, days to remission, and laboratory data. However, age at onset and interval to first relapse had a negative correlation with the frequency of relapse(Pearson's coefficient=-0.337, -0.433, P<0.012, P<0.01). Conclusion : The age at onset and the interval to first relapse were found to be predictive clinical parameters for the relapse rate, while the levels of serum IgG at initial presentation were a predictive laboratory factor for treatment response in childhood idiopathic nephrotic syndrome.

Objective : Thyroid-stimulating hormone (TSH)-secreting pituitary adenoma (PA) is an extremely rare functioning form of PA that accounts for 0.7-2% of all such cases. The previously reported outcomes of the surgical removal of TSH-PA are poor. Owing to its extremely low incidence, most available reports on TSH-PA are case reports or small case series. Thus, we investigated the clinical and endocrinological outcomes of surgically treated TSH-PA through our institutional series. Methods : We retrospectively reviewed 14 consecutive cases of surgically treated TSH-PA, focusing on the clinical, radiological, surgical, and endocrinological data. Results : There were seven male (50%) and seven female (50%) patients. The mean age was 42.5 years (range, 19-63). The mean tumor size was 16.6 mm (range, 4-30). Optic chiasm compression was noted in six patients (42.9%), and no patient showed cavernous sinus invasion. Thirteen of 14 patients (92.8%) underwent transnasal transsphenoidal approach (TSA), and one patient underwent TSA followed by transcranial approach for residual tumor removal. Thirteen of 14 patients (92.8%) showed endocrinological remission; all patients who experienced remission showed subnormal levels of TSH (<0.4 μU/mL) on postoperative day 2. Recurrence occurred in two patients (14.2%). One patient underwent subsequent revision transnasal TSA for recurrent tumor removal, and the other patient underwent gamma knife radiosurgery for recurrence. Conclusion : Surgical treatment showed excellent surgical outcomes. The TSH level in the immediate postoperative period may be a predictor for endocrinological remission.

Background/Aims: Colonic stenting as a bridge to elective surgery is an alternative for emergency surgery in patients with acute malignant colonic obstruction. However, since its benefits are uncertain, we aimed to establish whether it has better clinical outcomes. Methods: The patients with acute malignant left-sided colon obstruction enrolled from January 2009 to December 2018 in National Health Insurance Service Ilsan Hospital. The patients were enrolled to undergo colonic stenting as a bridge to elective surgery or emergency surgery. The following oncological outcomes were assessed: incidence of complete remission, disease progression, local recurrence, and systemic recurrence. Results: Out of 40 patients, 33 received self-expanding metallic stent (SEMS) as a bridge-to-surgery, and 7 underwent emergency surgery. More stoma was made in case of emergency surgery with statistical significance (p < 0.001). There were no significant differences in complete remission rate in curable left-sided malignant colonic obstruction between SEMS as a bridge-to-surgery and emergency surgery. Complete remission was achieved for 3 patients (42.9%) in the non-stent group and 27 patients (81.8%) in the stent group. There was no statistically significant difference in oncologic outcomes between the two groups (p = 0.069). According to multi-variate analysis, advanced TNM stage, Adjuvant chemotherapy, and SEMS bridge-to-surgery were significantly associated with disease-free survival. Disease-free survival rate differed significantly between the two groups (p = 0.024). Conclusions: SEMS as a bridge-to-surgery might be an effective strategy and reduce stoma formation in acute malignant left-sided colon obstruction.
