  • Adenocarcinomas (AC) are the most frequently encountered carcinomas. It may be quite challenging to detect the primary origin when those carcinomas metastasize and the first finding is a metastatic tumor. This study evaluated the role of sex hormone binding globulin (SHBG) positivity in tumor cells in the subclassification and detection of the original organ of adenocarcinomas. Between 1994 and 2008, 64 sections of normal tissue belonging to ten organs, and 116 cases diagnosed as adenoid cystic carcinoma and mucoepidermoid carcinoma of the salivary gland, lung adenocarcinoma, invasive ductal carcinoma of the breast, adenocarcinoma of stomach, colon, gallbladder, pancreas and prostate, endometrial adenocarcinoma and serous adenocarcinoma and mucinous adenocarcinoma of the ovary, were sent to the laboratory at the Department of Pathology at the Yuzuncu Yil University School of Medicine, where they were stained immunohistochemically, using antibodies against SHBG. The SHBG immunoreactivity in both the tumor cells and normal cells, together with the type, diffuseness and intensity of the staining were then evaluated. In the differential diagnosis of the adenocarcinomas of the organs, including the glandular structures, impressively valuable results are encountered in the tumor cells, whether the SHBG immunopositivity is evaluated alone or together with other IHC markers. Further extensive research with a larger number of cases, including instances of cholangiocarcinoma and cervix uteri AC [which we could not include in the study for technical reasons] should be performed, in order to appropriately evaluate the role of SHBG in the differential diagnosis of AC.

  • Skeletal malocclusion is the result of abnormal dimension and alignment of each skeletal component. Understanding on these mechanisms may help to elucidate the etiology of skeletal malocclusion and to establish population-oriented treatment plans. Attempts to subdivide the Angle's classification have been performed for Class III malocclusion, while few studies have been conducted for Class II malocclusion despite recent growing interests in Class II malocclusion. 200 adults (88 male, 112 female) with skeletal Class II malocclusion were collected and subdivided using cluster analysis, using the measurements representing the dimension and the alignment of each facial skeletal component. The properties of each cluster was grouped within the subjects and a comparison between the subjects and the control group (38 male, 35 female) with normal occlusion was performed. Six clusters were finally recognized in each male and female groups. The clusters in both genders were mainly characterized by the cranial base alignment, dimension of the posterior cranial base, dimension of the mandibular ramus and the degree of mandibular rotation. The results implicate that active treatment of mandible rather than the nasomaxillary complex may be primarily considered for the correction of Korean Class II skeletal pattern.

  • Cytologic and histopathologic features and human papillomavirus (HPV) DNA detection associated with 101 cervicovaginal smears which are ciassified as 'atypical squamous cells of undetermined significance, rule out high grade squamous intraepithelial lesion(ASCUS, R/O HSIL)' were reviewed and compared to 89 smears of 'ASCUS, not otherwise specified(NOS)'. Cytologic fieatures of ASCUS, R/O HSIL included atypical single small cells(36.6%), hyperchromatic tissue flagments(35.6%), atypical metaplastic cells(18.8%), endometrial cell-like clusters(5.9%), and atypical parakeratotic cells(3.0%). A final diagnosis of HSIL on biopsy was assigned to 47(54.0%) of 87 women with ASCUS, R/O HSIL and to 13(14.6%) of 89 women with ASCUS, NOS (p=0.000). There was no difference in HPV DNA detection late between ASCUS, R/O HSIL and ASCUS, NOS smears. These data suggest that subclassification of ASCUS is helpful to manage patients because ASCUS, R/O HSIL is more often associated with an underlying HSIL on biopsy. Therefore, women with ASCUS, rule out HSIL should be actively managed with colposcopic examination.

  • Charcot-Marie-Tooth (CMT) disease was described by Charcot and Marie in France and, independently, by Tooth in England in 1886. CMT is the most common form of inherited motor and sensory neuropathy, and is a genetically heterogeneous disorder of the peripheral nervous system. Therefore, many genes have been identified as CMT-causative genes. Traditionally, subclassification of CMT have been divided into autosomal dominant inherited demyelinating (CMT1) and axonal (CMT2) neuropathies, X-linked neuropathy (CMTX), and autosomal recessive inherited neuropathy (CMT4). Recently, intermediate type (CMT-Int) with NCVs between CMT1 and CMT2 is considered as a CMT type. There are several related peripheral neuropathies, such as $D{\acute{e}}j{\acute{e}}rine$-Sottas neuropathy (DSN), congenital hypomyelination (CH), hereditary neuropathy with liability to pressure palsies (HNPP) and giant axonal neuropathy (GAN). Great advances have been made in understanding the molecular basis of CMT, and 17 distinct genetic causes of CMT have been identified. The number of newly discovered mutations and identified genetic loci is rapidly increasing, and this expanding list has proved challenging for physicians trying to keep up with the field. Identifying the genetic cause of inherited neuropathies is often important to determine at risk family members as well as diagnose the patient. In addition, the encouraging studies have been published on rational potential therapies for the CMT1A. Now, we develop a model of how the various genes may interact in the pathogenesis of CMT disorder.

  • 목적 : 소아 IgA 신병증을 Haas에 의한 조직 병리학적 분류로 분류하고 이들의 임상 소견과 수년간의 추적 관찰을 통하여 임상 경과, 신기능저하의 빈도 및 위험인자를 알아보고자 본 조사를 시행하였다. 방법 : 대상 환아는 과거 11년간 경북대학교병원 소아과에 입원하여 신생검 소견상 IgA 신병증으로 진단된 60례로 하였으며 이들을 Haas의 subclass로 분류하고 임상 소견과 각종 검사실 성적을 비교 관찰하였고 또한 3-4년간의 추적 관찰을 통하여 각 subclass의 임상 경과, 신기능저하의 빈도 등을 알아보았다. 결과 : Haas의 조직학적 분류에 의한 subclass는 I 10례, III 36례, IV 12례, V 2례였으며 subclass II는 한 례도 없었다. 성별 분포는 남아 45례 여아 15례로 남아에 호발하였으며 (남 : 여 = 3 : 1) 평균 발병 연령은 $10.4{\pm}2.8$세로서 subclass에 따른 차이는 없었다. 육안적 혈뇨가 71.7%를 차지하였으며 진단 당시 고혈압이 2례, 질소혈증이 3례에서 관찰되었다. 혈청 단백과 알부민치는 subclass IV 및 V에서 각각 $6.3{\pm}1.1,\;3.3{\pm}0.9$$4.5{\pm}1.1,\;2.1{\pm}0.3g/dL$로서 subclass가 증가함에 따라 감소하였으며 24시간 뇨단백 배설양 ($mg/m^2/day$)은 subclass가 증가함에 따라 배설양도 증가하여 subclass IV는 $1338{\pm}1031$, subclass V는 $4500{\pm}1500$의 심한 단백뇨를 보여주었다. 혈청 IgA치는 28.3%에서 증가되어 있었으며 subclass의 정도 및 환아의 임상 경과와는 무관하였다. 추적 관찰 기간중 첫 1-2년에 14%, 3-4년에는 37.1%에서 정상 뇨소견(혈뇨의 소실)이 관찰되었으며 subclass에 따른 차이는 없었다. 점진적인 신기능 저하를 보인 경우는 3례로서 이들은 Haas의 subclass III, IV 및 V가 각각 1례씩이였다. 결론 : 소아에서의 IgA신병증의 예후는 지금까지 알려져 온 것보다 만성 신부전으로의 진행이 높은 것으로 생각되며 Haas의 조직학적 분류가 예후 판정에 도움이 된다고 생각한다. 그러나 본 연구는 대상 환아 및 추적 관찰 기간이 짧았기 때문에, 앞으로는 다 기관 공동 연구에 의하여 더 많은 예 수와 10년 이상의 장기 추적관찰에 의한 광범위한 연구가 이루어져야 할 것으로 생각한다.

  • Purpose : This Study was conducted to evaluate clinical characteristic of children with recurrent abdominal pain (RAP) and to be classified by its six subtype in the Oriental Pediatric Text Book and to find out relationship of western classification. Methods : Patients who visited Dong-Eui Oriental Medical hospital from August, 2001 to October, 2002 due to RAP were included. According to questionnaire and history taking, RAP was classified by its six subtype based on Oriental medical theory. Results : 1. Patients with RAP were more internalized, have a close relation with their parents, and have strong desires of success, but social intercourse is low. 2. 76% of Patients have a less desire to eat and 67% of Patients have a diarrhea or constipation. 3. According to questionnaire, first abdominal pain was their $3{\sim}5$ ages most, cause of occurrence was more 'eating cold foods' most, time of AP (abdominal pain) was $1{\sim}2$ hours after eating and no characteristic most, site of AP was the umbilicus most, shape of AP was impotent pain most, cause of reduce pain was abdominal massage and defection most. 4. frequency of RAP's type, AP caused by diet(食積腹痛) is 45.5%, AP caused by cold(寒腹痛) is 29.1%, AP caused by cold in internal organs of deficiency(臟腑虛冷腹痛) is 12.7%, stagnation of qi and stasis of blood(氣滯血瘀腹痛) is 10.9%, AP caused by internal diet and external cold(內食外寒腹痛) is 1.8%. There is no AP caused by parasites(蟲腹痛). 5. During clinical classifications of RAP, cause of occurrence was most important cause of reduce pian, defection practice was helpful for diagnosis, but shape of AP, site of AP was not helpful. 6. With relationship of Oriental classification and western classification, AP caused by diet is similar to dysmotilitylike dyspepsia and irriTable bowel syndrome. AP caused by cold is similar to irriTable bowel syndrome. AP caused by cold in internal organs of deficiency is similar to unspecified dyspepsia. stagnation of qi and stasis of blood and AP caused by internal diet and external cold is not like to western classification. Conclusion : RAP in Childhood is most occurred by food and cold. there is few AP caused by stagnation of qi and stasis of blood and internal diet and external cold. So the study on subclassification and clinical Manifestations of RAP in Childhood is more performed.

  • Background: Neoadjuvant systemic chemotherapy is the accepted approach for women with locally advanced breast cancer. Anthracycline- and taxane-based regimens have been extensively studied in clinical trials and consequently are widely used. In this study aimed to research the complete response (pCR) rates in different regimens for neoadjuvant setting and determine associated clinical and biological factors. Methods: This study included 63 patients diagnosed with breast carcinoma among 95 patients that had been treated with neoadjuvant chemotherapy between 2007 and 2010. TNM staging system was used for staging. The histologic response to neoadjuvant chemotherapy was characterized as a pCR when there was no evidence of residual invasive tumor in the breast or axillary lymph nodes. Biologic subclassification using estrogen receptor (ER), progesterone receptor (PR), HER2 were performed. Luminal A was defined as ER+, PR+, HER2-; Luminal B tumor was defined as ER+, PR-, HER2-; ER+, PR-, HER2+; ER-, PR+, HER2-; ER+, PR+, HER2+; HER2 like tumor ER-, PR+, HER2+; and triple negative tumor ER, PR, HER2 negative. Results: Patients median age was 54.14 (min-max: 30-75). Thirty-two patients (50.8%) were premenapousal and 31 (49.2%) were postmenapousal. Staging was performed postoperatively based on the pathology report and appropriated imaging modalities The TNM (tumor, lymph node, metastasis) system was used for clinical and pathological staging. Fifty-seven (90.5%) were invasive ductal carcinomas, 6 (9.5%) were other subtypes. Thirty nine (61.9%) were grade II and 24 (38.1%) were grade III. Seven (11.1%) patients were stage II and 56 (88.9) patients were stage III. The patients were classified for ER, PR receptor and HER2 positivity. Seventeen patients had complete response to chemotherapy. Forty patients (63.5%) were treated with dose dense regimen (cyclophosphamide 600 mg/m2 and doxorubicine 60 mg/m every two weeks than paclitaxel 175 mg/m2 every two weeks with filgrastim support) 40 patients (48%) were treated anthracycline and taxane containing regimens. Thirteen patients (76%) from 17 patients with pCR were treated with the dose dense regimen but without statistical significance (p=0.06). pCR was higher in HER2(-), ER(-), grade III, premenopausal patients. Conclusion: pCR rate was higher in the group that treated with dose dense regimen, which should thus be the selected regimen in neoadjuvant setting. Some other factors can predict pCR in Turkish patients, like grade, menopausal status, triple negativity, percentage of ER positivity, and HER2 expression.

  • In this study, the features of canine lymphoma on fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) were evaluated in three small breed dogs. In case 1, ultrasonography and CT indicated neoplastic involvement of the sternal, right axillary, submandibular, lower cervical, tracheobronchial, mesenteric, and sublumbar lymph nodes; spleen; and liver. However, intense FDG uptake on PET/CT images was detected only for the lymph nodes and spleen. No FDG uptake by the liver was detected for case 1 despite the confirmation of lymphoma by cytology. In case 2, ultrasonography and CT indicated neoplastic involvement of the axillary, mesenteric, and sublumbar lymph nodes and the spleen, while intense FDG uptake on PET/CT images was detected for the axillary and a few mesenteric lymph nodes, and the spleen. FDG uptake was additionally observed from popliteal lymph nodes, however there was no uptake by the sublumbar lymph nodes and some mesenteric lymph nodes. In case 3, neoplastic changes in the splenic, mesenteric, and sublumbar lymph nodes and spleen were suspected on ultrasonography, and lower cervical and popliteal lymph node involvements were additionally detected on PET/CT. Compared to ultrasonography, repeated PET/CT showed increased FDG uptake by the lymph nodes at an earlier stage after chemotherapy in case 3. This study illustrated the features of PET/CT in canine lymphomas and compared those to ultrasonography and CT findings. FDG uptakes were not detected from some lesions which were suspected to be neoplastic involvement in case 1 and 2. We could not clearly explain the reason of this result in the present study because cytological or histological examination was not performed for lesions that showed different results on ultrasonography, CT, and PET/CT. Further studies on the subclassification of canine lymphoma and the sensitivity and specificity of PET/CT for the detection of canine lymphoma are required. PET/CT data can provide useful information for predicting the therapeutic response at an early stage after treatment.

  • The purpose of study is for the defining the diagnostic criteria of Jung-Pung (中風) which are confused or unclear partially or Oriental Medicine. The results were obstained as follows ; 1. The Diagnosis of Jung-Pung (中風) can be accomplished by the name of disease, symptomatic classification, Byun-Jeung (辨證), stage, assessment of neurological deficit. 2. The various expressive way on the names of Jung-Pung (中風) can be unified as Jung-Pung (中風). 3. The symptomatic classification of Jung-Pung (中風) can be Jung-Kyung-Rak (中經絡) and Jung-Jang-Bu (中臟腑) by unconsciousness. 4. The subclassification of Jung-Kyung-Rak(中經絡) is Kanyangpokhang Punghwa sangyo (肝陽暴亢 風火上擾證), PungDamErHyul BiJoMaecRak (風痰瘀血 痺阻脈絡證), DamYeolBusil PoongDamSangYo (痰熱腑實 風痰上擾證), KiHerhyulEr (氣虛血瘀證), YeumHer PungDong (陰虛風動證) and Jung-Jang-Bu (中臟腑) is PungHwa SangYo CheongGeu (風火上擾淸竅證), DamSeupMongSac ShimSin (痰濕蒙塞心神證), DamYeolNaeFe ShimGeu (痰熱內閉心竅證), WonKiFaeTal ShimSinChakRan(元氣敗脫心神錯亂證) 5. The classification of stages can be divided as stroke stage, convalescent stage, complicated deficit stage. 6. In Oriental Medicine there were few assessment methods of neurological deficit. Therefore we need to develop new assessment system or modification of Western Medicine. The Standardization in the diagnosis of Jung-Pung (中風) has not been well established, even though we had have many clinical experiences. So it is necessary to make a accurate diagnosis that can be done by multiple diagnostic assessment. Therefore the accurate diagnosis of Jung-Pung (中風) can be done by 5 factors, they are the name of diagnosis, symptomatic classification, Byun-Jeung (辨證), stage, the assessment of neurological dificit. And it can be applied in the planning of treatment.

  • 목적: 저자들은 소아 IgA 신병증 환자를 대상으로 세뇨관 상피세포에서 ICAM의 발현이 신 손상의 예후인자로서 역할을 할 수 있는지를 알아보기 위하여, 신세뇨관 ICAM-1 발현과 조직소견 및 임상소견과의 연관성을 조사하고자 본 연구를 시행하였다. 방법: IgA 신병증으로 진단된 43명의 환자를 후향적으로 분석하였고, Haas가 제안한 분류법에 따라 subclasses에 따라 비교하였다. 그리고 LSAB kit를 이용하여 세뇨관 상피 세포의 ICAM-1의 발현도를 평가했다. 결과: IgA 신병증으로 진단된 43명의 평균 연령은 $12.2{\pm}2.2$세였으며, 남자 28명, 여자 15명이었다. 육안적 혈뇨에 따른 신세뇨관 ICAM-1 발현의 차이는 발견할 수 없었다. 그러나 단백뇨가 동반되었던 환자의 신세뇨관 ICAM-1의 발현율은 단백뇨가 없었던 환자들의 발현율에 비해 통계적으로 유의하게 높았다$78.2{\pm}14.19%\;vs\;55.8{\pm}32.20%,\;P<0.05$. Haas의 조직학적 분류의 subclasses에 따른 ICAM-1의 발현율은 subclass가 증가할수록 ICAM-1의 발현율도 증가하였다. 신세뇨관 ICAM-1의 발현과 24시간 채집뇨의 총단백량 그리고 신세뇨관 ICAM-1의 발현과 조직학적 분류간의 상관성은 Spearmann 상관분석상 각각 통계적으로 유의한 상관관계를 보였다. 그러나 간질 염증세포 침윤, 섬유화, 신세뇨관 위축 정도와는 통계학적으로 유의한 상관관계를 보이지 않았다. 결론: 소아 특발성 IgA 신병증에서 신세뇨관 ICAM-1의 발현은 신 손상 특히 사구체 손상의 정도를 잘 반영하고 있으며 예후 인자로서도 유용하게 이용할 수 있다고 생각한다.
