  • 연구배경: Interferon-gamma assay는 잠복 결핵의 진단에서 투베르쿨린 피부 반응 검사를 대신할 수 있는 검사 방법으로 주목 받고 있다. 그러나 활동성 결핵의 진단 시Interferon-gamma assay의 유용성에 대해서는 많은 이견이 있다. 따라서 결핵 발병률이 중등도인 우리 나라에서 Interferon-gamma assay의 임상적 유용성을 알아보고자 하였다. 방 법: 2007년 1월부터 2007년 8월까지 강동성심병원 호흡기내과에 내원한 환자 중 활동성 결핵이 의심되는 환자 52명을 대상으로 흉부 방사선 검사, 객담 도말 검사, 객담 배양 검사, PCR 검사, QuantiFERON-TB GOLD test를 시행하였다. 흉막 삼출액이 있는 환자의 경우 흉수 검사 및 흉막 조직 검사를 시행하였다. 결 과: 이번 연구에 포함된 52명의 환자 중 35명이 최종적으로 활동성 폐결핵으로 진단 되었고, 이 중 25명이 QuantiFERON-TB GOLD 검사 양성, 10명이 Quanti-FERON-TB GOLD 검사 음성 소견을 보였다. 본 연구에서 QuantiFERON-TB GOLD 검사의 민감도는 71.4%, 특이도는 64.7%였고, 양성 예측도는 0.83, 음성 예측도는 0.50였다. QuantiFERON-TB GOLD 검사 양성인 군과 음성인 군에서 C 반응성 단백값을 제외하고 두 군간에 큰 차이는 보이지 않았다. C 반응성 단백값은 QuantiFERON-TB GOLD 검사 양성인 군에서 29.25${\pm}$27.30 mg/L, Quanti-FERON-TB GOLD 검사 음성인 군에서 72.90${\pm}$67.98 mg/L로 QuantiFERON-TB GOLD 검사 음성인 군에서 통계적으로 유의하게 높게 나타났다(p<0.05). 결 론: 본 연구에서는 QuantiFERON-TB GOLD 검사는 활동성 폐결핵 진단에 유용성이 크지 않은 것으로 나타났다. QuantiFERON-TB GOLD 검사 결과와 C 반응성 단백값의 상관 관계는 추후 연구가 더 필요할 것으로 사료된다.

  • Diagnosis of acute appendicitis in children is sometimes difficult. The aim of this study is to validate a clinical scoring system and ultrasonography for the early diagnosis and treatment of appendicitis in childhood. This is a prospective study on 59 children admitted with abdominal pain at St. Mary's Hospital, the Catholic University of Korea from July 2002 to August 2003. We applied Madan Samuel's Pediatric Appendicitis Score (PAS) based on preoperative history, physical examination, laboratory finding and ultrasonography. This study was designed as follows: patients with score 5 or less were observed regardless of the positive ultrasonographic finding, patients with score 6 and 7 were decided according to the ultrasonogram and patients above score 8 were operated in spite of negative ultrasonographic finding. The patients were divided into two groups, appendicitis (group A) and non-appendicitis groups (group B). Group A consisted of 36 cases and Group B, 23 cases. Mean score of group A was 8.75 and group B was 6.13 (p<0.001). Comparing the diagnostic methods in acute appendicitis by surveying sensitivity, specificity, positive predictive value, negative predictive value, and accuracy, PAS gave 1.0000, 0.3043, 0.6923, 1.0000, and 0.7288, and ultrasonography gave 0.7778, 0.9130, 0.9333, 0.7241, and 0.8300 while the combined test gave 1.0000, 0.8696, 0.9231, 1.0000, and 0.9490, respectively. Negative laparotomy rate was 3 %. In conclusion, the combination of PAS and ultrasonography is a more accurate diagnostic tool than either PAS or ultrasonography.

  • Hashimoto's encephalopathy (HE) is a rare and underdiagnosed neuropsychiatric illness. We present the case of a 17-year-old girl who was admitted to a tertiary-care psychiatric center with acute onset psychosis and fever. Her psychotic symptoms were characterized by persecutory and referential delusions, as well as tactile and visual hallucinations. Her acute behavioral disturbance warranted admission and treatment in a psychiatric setting (risperidone tablets, 3 mg/day). She had experienced an episode of fever with a unilateral visual acuity defect approximately 3 years before admission, which was resolved with treatment. Focused clinical examination revealed an enlarged thyroid, and baseline blood investigations, including thyroid function test results were normal. Abnormal laboratory investigations revealed elevated anti-thyroid peroxidase (anti-TPO) and anti-thyroglobulin (anti-TG) levels (anti-TPO of 480 IU/mL; anti-TG of 287 IU/mL). Results of other investigations for infection, including cerebrospinal fluid examination, electroencephalography, and brain magnetic resonance imaging were normal. She was diagnosed with HE and was treated with intravenous corticosteroids (methylprednisolone up to 1 g/day; tapered and discontinued after a month). The patient achieved complete remission of psychotic symptoms and normalization of the anti-thyroid antibody titers. Currently, at the seventh month of follow-up, the patient is doing well. This case highlights the fact that in the absence of well-defined clinical diagnostic criteria, a high index of suspicion is required for early diagnosis of HE. Psychiatrists need to explore for organic etiologies when dealing with acute psychiatric symptoms in a younger age group.

  • Since dissociative identity disorder (DID) has symptoms similar to schizophrenia, such as auditory hallucinations and delusional thoughts of being controlled, there are difficulties in its differential diagnosis. A 16-year-old adolescent male patient who was previously diagnosed with schizophrenia from a different hospital was admitted to our inpatient psychiatric unit for the evaluation of auditory hallucinations and suicide attempts. Through psychiatric evaluations, it was determined that the patient suffered from identity alternation, dissociation, and amnesia. As for the diagnostic evaluations, the following measures were implemented: a psychiatric interview regarding the diagnostic criteria, mental status examination, laboratory tests, brain imaging studies, electroencephalography, and full psychological test for adolescents, and the self-reported measure of the Adolescent Dissociative Experiences Scale. The patient was diagnosed with DID, and the following treatments were administered: pharmacotherapy, ego state therapy, psychoeducation regarding emotions, trauma-focused psychotherapy including stabilization, and family therapy. Following treatment, in the internal dimensions, the patient was able to recognize the nine alternate identities in charge of his emotions, which established a basis for the potential integration of identities. In the external dimensions, he showed improvements in the aspects of family conflicts and issue of school refusal. This is the first reported case of DID in an adolescent in Korea; it emphasizes the consideration of DID in the differential diagnosis of other mental illnesses such as schizophrenia, bipolar disorder, and posttraumatic stress disorder and expands the treatment opportunities for DID by sharing the procedures of ego state therapy.

  • Background: Missing isoniazid (INH) resistance during tuberculosis (TB) diagnosis can worsen the outcomes of INH-resistant TB. The BD MAX MDR-TB assay (BD MAX) facilitates the rapid detection of TB and INH and rifampin (RIF) resistance; however, data related to its performance in clinical setting remain limited. Moreover, its effect on treatment outcomes has not yet been studied. Methods: We compared the performance of BD MAX for the detection of INH/RIF resistances to that of the line probe assay (LPA) in patients with pulmonary TB (PTB), using the results of a phenotypic drug sensitivity test as a reference standard. The treatment outcomes of patients who used BD MAX were compared with those of patients who did not. Results: Of the 83 patients included in the study, the BD MAX was used for an initial PTB diagnosis in 39 patients. The sensitivity of BD MAX for detecting PTB was 79.5%. The sensitivity and specificity of BD MAX for INH resistance were both 100%, whereas these were 50.0% and 95.8%, respectively, for RIF resistance. The sensitivity and specificity of BD MAX were comparable to those of LPA. The BD MAX group had a shorter time interval from specimen request to the initiation of anti-TB drugs (2.0 days vs. 5.5 days, p=0.001). Conclusion: BD MAX showed comparable performance to conventional tests for detecting PTB and INH/RIF resistances. The implementation of BD MAX as a diagnostic tool for PTB resulted in a shorter turnaround time for the initiation of PTB treatment.
