  • 치아종은 치성 종양 중 가장 흔한 형태로 대체로 병소의 크기나 위치에 따라 증상이 없는 경우가 대부분이며 성장이 제한적이다. 보통 10대 이전에 주로 진단되며 종종 영구치의 매복이나 맹출 지연을 유발한다. 형태에 따라 복합 치아종과 복잡 치아종으로 구별된다. 복잡 치아종은 치성 조직이 조직화되지 않은 덩어리로 형태학적으로 정상 치아 형태를 닳지 않으며 전체 치아종의 약 25%, 악골내 발생하는 치성 종양의 약 22%를 차지하고 남성에서 하악 구치부에 호발한다. 치아종의 원인은 아직 밝혀져 있지 않으나, 아마도 해당 부위의 국소적인 외상, 감염, 유전적 원인이 관여 할 것이라 추측된다. 치아종의 치료는 대부분 보존적인 외과적 적출술이 추천되며 재발은 거의 없다. 본 증례는 상악 제 1대구치의 매복을 일으킨 복잡 치아종으로 진단된 두 어린이에게서 병소의 외과적 적출술 및 개창술을 시행하고 관찰한 결과 약 2년후 제 1 대구치가 자발적으로 맹출함을 보여 이에 보고하는 바이다.

  • 목 적: 난소 용적 측정 및 기저 FSH, $E_2$, CCCT 검사를 통하여 가임기 여성에서 난소 낭종 제거술후 난소 배란능의 변화를 평가하고자 하였다. 연구방법: 난소 낭종으로 내원한 환자 중 35세 이하의 여성으로서 비교적 규칙적인 생리주기를 가지며 한쪽 난소에만 낭종을 가진 22명을 대상으로 자궁내막종군과 비자궁내막종군으로 구분하여 전향적 비교 분석을 시행하였다. 질 초음파를 이용하여 수술 1개월 전과 수술 3개월 후 생리주기 3일에 난소의 용적을 측정하였다. 또한 수술 전과, 수술 후 두 번의 정상 생리가 있은 뒤 기저 FSH, $E_2$, CCCT를 시행하였다. 대상 환자 22명 중 3명은 술후 검사를 계획한 3개월 전에 임신이 됨으로써 연구대상에서 제외하였다. 결 과: 수술 후 난소 용적은 자궁내막종군에서 $4.79{\pm}2.57\;cm^3$, 비자궁내막종군 중 직경 ${\geq}10\;cm$인 경우에서 $5.21{\pm}1.33\;cm^3$로서 건측과 비교하여 유의한 감소가 있었으나, 비자궁내막종군 중 직경 <10 cm인 경우는 $6.18{\pm}2.85\;cm^3$로서 유의한 용적 감소가 없었다. 수술후 자궁내막종군의 기저 FSH는 $4.25{\pm}0.20\;mIU/ml$, CCCT 10일째 FSH는 $3.79{\pm}0.80\;mIU/ml$였고, 비자궁내막종군은 각각 $4.24{\pm}0.85\;mIU/ml$, $4.28{\pm}0.92\;mIU/ml$로서 수술 전후의 기저 FSH, CCCT 결과 비교에서 각 군 모두 유의한 차이가 없었으며, 두 군간의 비교에서도 유의한 차이가 없었다. 결 론: 자궁내막종 절제술 및 10 cm 이상의 난소 낭종 절제술 후 난소 용적은 유의한 감소를 보였으나 10 cm 미만의 난소 낭종 제거술에서는 난소 용적의 유의한 감소가 없었다. 난소 배란능을 평가하기 위하여 측정한 기저 FSH, CCCT 검사 결과는 낭종 제거술 후에도 각 군 모두 유의한 차이를 보이지 않았다. 따라서 가임기 여성에서는 난소절제술 보다는 낭종 제거술이 우선 고려되어야 하며, 세심한 주의를 기울인다면 난소 배란능의 손상을 최소화할 수 있을 것으로 사료된다.

  • Torticollis is a deformity of the neck that shows tilting of the head toward the affected side and rotation of the chin toward the opposite side. In many cases with this condition, unilateral tightness of the sternocleidomastoid muscle is found frequently with fibrous tumor. The analysis of 43 cases of congenital muscular torticollis and result of their physical therapy are reported. The research was from Jan. 1, 1990 to Dec. 31, 1995 at Ulsan Dong Kang Hospital. The results obtained were as follows. 1. There were 30 males(69.8%) and 13 females(30.2%). Age distribution of patients showed below 2 month 20 cases(46.5%), above 1 year 7 cases(16.3%), $5{\sim}6/11{\sim}12$ months 4 cases(9.3%), and $7{\sim}8$ month 2 cases(4.6%). 2. 25 cases(58.1 %) were on the right and 18 cases(41.9%) on the left side. Torticollis was mild to moderately severe in mild 22 cases(51.1 %), moderate 18 cases (41.9 %) and severe 3 cases(7%). 3. There were normal spontaneous delivery in 36 cases(83.7%), Cesaean section in 4 cases (9.3%) and breech presentation in 3 cases(7%). Sequence of birth, the 1st born babys were 30 cases(69.8%) and the 2nd born babys were 13 cases(30.2%). 4. Above fair result of physiotherapy were 36 cases(83.7%). 5. Of the 43 cases with fellow up, above fair 32 cases(74.4%) and poor 11 cases(25.6%) showed. As conclusion, passive stretch exercise of sternocleidomastoid muscle with early torticollis diagnosis seems more successful in recovery than no exercise.

  • Objective : It is difficult to differentiate intramedullary spinal cord tumors preoperatively from non-neoplastic pathologies in patients presenting as non-compressive myelopathies in magnetic resonance imaging(MRI). In this report, the authors reviewed nonneoplastic intramedullary spinal cord lesions preoperatively diagnosed as tumors and discussed their clinical and radiological characteristics and usefulness of surgical intervention. Methods : From January, 1985 to January, 1999, authors experienced eight non-neoplastic pathologies mimicking intramedullary spinal cord tumors and analysed their medical records, radiological findings and histopathological specimens retrospectively. Results : There were five males and three females and the duration of symptoms were from two to 20 months(mean, 9.8 months). The location of lesions were four cervical, one cervicothoracic and three thoracic. All patients manifested sensory abnormality, seven motor weakness, and six bladder symptom. All cases had swollen spinal cords and increased signal intensities in spin-echo sequences. Six cases showed contrast enhancement : four cases were focal and two diffuse. Under the impression of intramedullary tumors, the patients were operated upon. Final diagnoses on the base of clinical and pathologic finding were : three subacute necrotizing myelopathies, two multiple scleroses, two myelopathy of unknown etiology. One case showed no gross abnormality in surgical field in spite of adequate exposure of the lesion, so biopsy was not performed. In that case, postoperative MRI revealed spontaneous resolution of the lesion. Conclusion : MRI is invaluable diagnostic tool in screening myelopathies. However, its high sensitivity and lack of specificity make difficulty in preoperative differential diagnosis of non-compressive myelopathies. Although no surgical morbidity occurred in our series, we sometimes failed to confirm definite diagnosis even with biopsy. In such a circumstance, long-term follow up is needed.

  • 심장의 원발성 종양은 소아에서는 매우 드문 질환이다. 횡문근종은 태아, 영아 및 소아 연령에서 가장 흔한 원발성 심장 종양으로 결절성 경화증이 동반되는 것으로 보고되고 있다. 결절성 경화증은 뇌, 심장, 피부 및 기타 장기들을 침범하는 신경피부 증후군으로, 결절성 경화증을 가진 영아의 50-64%에서 동반된다. 심장 횡문근종은 종괴는 심방을 비롯하여 심실 중격과 심실벽에 다발성으로 존재하며 종양의 위치와 크기, 침범 정도에 따라 심장 유출로 협착 및 심부전과 같은 여러 가지 임상 양상을 보일 수 있다. 드물지만 부정맥을 주증상으로 발현하는 경우도 보고되고 있다. 하지만 대부분 심장의 횡문근종이 특별한 문제를 일으키지 않고 성장과 함께 쇠퇴되는 경향을 보이므로 극히 일부분에서만 장기적인 항부정맥제 사용이 요구된다. 환자의 최종적인 예후는 동반되는 뇌병변에 의해 결정되는 경향이 있다. 저자들은 상심실성 빈맥으로 입원치료 중 진단된 심장 횡문근종을 가진 결절성 경화증 1예를 경험하였기에 보고하는 바이다.

  • In our preliminary study to find antiviral or antitumor agents from Korean natural products, we found that the Shope fibroma virus (SFV) induced fibromas reaching maximum size at $5{\sim}6$ days with spontaneous disappearance at $15{\sim}20$ days after SFV intracutaneous inoculation into Korean domestic rabbits. However, the sizes of fibromas of rabbits at day 5 after virus inoculation were significantly different individually. Assuming that the variation of tumor size was due to either susceptibility or the preexisting antibodies against SFV in the Korean domestic rabbits, the rabbits were checked for the antibodies against SFV by IFAT using SFV infected RK13 cells. The antibody positive rate of normal Korean domestic rabbits was 32.8% and the sizes of the fibromas of the positive rabbits were significantly smaller than those of negative rabbits (p<0.0001). The fibroma sizes were dependent on the antibody titers of rabbits to SFV. The sizes of fibromas after inoculation of SFV into immunized rabbits were about one tenth of those by the first inoculation into normal rabbits. This is the first report on the antibody prevalence against SFV among normal Korean domestic rabbits and it suggest the existence of a wild fibroma virus or related virus in Korea.

  • Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder characterized by motor, cognitive, and psychiatric symptoms, accompanied by marked cell death in the striatum and cortex. Stereotaxic injection of quinolinic acid (QA) into striatum results in a degeneration of GABAergic neurons and exhibits abnormal motor behaviors typical of the illness. The objective of this study was carried out to obtain basic information about whether parthenogenetic mouse embryonic stem (PmES) cells are suitable for cell replacement therapy of HD. To establish PmES cell lines, hybrid F1 (C57BL/6xCBA/N) mouse oocytes were treated with 7% ethanol for 5 min and cytochalasin-B for 4 hr to initiate spontaneous cleavage. Thus established PmES cells were induced to differentiate using bFGF (20ng/ml) followed by selection of neuronal precursor cells for 8 days in N2 medium. After selection, cells were expanded at the presence of bFGF (20 ng/ml) for another 6 days, then a final differentiation step in N2 medium for 7 days. To establish recipient animal models of HD, young adult mice (7 weeks age ICR mice) were lesioned unilaterally with a stereotaxic injection of QA (60 nM) into the striatum and the rotational behavior of the animals was tested using apomorphine (0.1mg/kg, IP) 7 days after the induction of lesion. Animals rotating more than 120 turns per hour were selected and the differentiated PmES cells (1$\times$10$^4$cells/ul) were implanted into striatum. Four weeks after the graft, immunohistochemical studies revealed the presence of cells reactive to anti-NeuN antibody. However, only a slight improvement of motor behavior was observed. By Nissl staining, cell mass resembling tumor was found at the graft site and near cortex which may explain the slight behavioral improvement. Detailed experiment on cell viability, differentiation and migration explanted in vivo is currently being studied.

  • Background: Carcinoid crisis is a life-threating syndrome of neuroendocrine tumors (NETs) characterized by dramatic blood pressure fluctuation, arrhythmias, and bronchospasm. In the era of booming anti-tumor therapeutics, this has become more important since associated stresses can trigger carcinoid crisis. Somatostatin analogues (SSTA) have been recommended for prophylactic administration before intervention procedures for functioning NETs. However, the efficacy is still controversial. The aim of this article is to review efficacy of SSTA for preventing carcinoid crisis. Materials and Methods: PubMed, Cochrane Controlled trials Register, and EMBASE were searched using 'carcinoid crisis' as a search term combining terms with 'somatostatin'; 'octreotide'; 'lanreotide' and 'pasireotide' until December 2013. Results: Twenty-eight articles were retrieved with a total of fifty-three unique patients identified for carcinoid crisis. The most common primary sites of NETs were the small intestine and respiratory tract. The triggering factors for carcinoid crisis included anesthesia/surgery (63.5%), interventional therapy (11.5%), radionuclide therapy (9.6%), examination (7.7%), medication (3.8%), biopsy (2%) and spontaneous (2%). No randomized controlled trials (RCTs) were identified and two case-control studies were included to assess the efficacy of SSTA for preventing carcinoid crisis by meta-analysis. The overall pooled risk of perioperative carcinoid crisis was similar despite the prophylactic administration of SSTA (OR 0.44, 95% CI: 0.14 to 1.35, p=0.15). Conclusions: SSTA wasnot helpful for preventing carcinoid crisis based on a meta-analysis of retrospective studies. Attentive monitoring and careful intervention are essential. Future studies with better quality are needed to clarify any effect of SSTA for preventing carcinoid crisis.
