  • 소세포 폐암에 동반된 LEMS는 부종양성 증후군의 일종으로 LEMS가 진단된 환자의 50% 이상에서 소세포 폐암이 동반되는데 특히 흡연력이 있는 고령에서 잠재성암을 진단하기 위한 적극적인 노력이 필요하다. 저자 등은 기괸지경 검사상 조직학적으로 진단되지 않았으나 폐암이 강력히 의심되어 적극적으로 수술적 치료를 시행하여 소세포 폐암을 진단하였고, 수술 후 LEMS의 임상양상이 호전되었으며 항암 화학요법후 추가로 호전된 증례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

  • 최근 평균수명의 연장과 진단 및 치료 방법의 발달로 원발성 중복암의 발견율이 높아지고 있다. 폐와 간에 발생한 중복암, 특히 동시성 중복암에 대한 보고는 매우 드물다. 저자 등은 만성기침을 호소하는 73세 남자에서 폐의 편평상피세포암을 진단한 후, 복부초음파에서 간 종괴를 발견하여 폐암의 전이를 의심하였으나 FDG-PET에 간 전이가 없어서 초음파 유도로 간 생검을 시행한 결과 간세포암을 진단하여, 폐와 간의 동시성 중복암을 경험하였기에 문헌고찰과 더불어 보고한다.

  • Objective: The purpose of this study was to investigate effects of hand grip strength on the muscle activation of shoulder joint in breast cancer patients. Design: Cross-sectional study. Methods: Ten breast cancer patients who agreed to active participation were included. These patients were operated with either conservative surgery or segmental mastectomy, and then were treated with radiation therapy and chemotherapy. The activity of the upper trapezius, lower trapezius, supraspinatus and serratus anterior muscle were measured using surface electrodes during 4 hand gripping tasks (lowered their arms in standing position, 0%, 30%, and 50% of maximum voluntary contraction) in the scapular abduction plane. Results: The results were analyzed using a one-way repeated measures ANOVA. There was a significant difference in the lower trapezius and supraspinatus muscles according to grip strength, lower trapezius and supraspinatus muscles showed significantly difference according to grip strength (p<0.05). The result of the muscle activation according to hand strength (0%, 30%, and 50%) it showed a significant difference between the upper trapezius and supraspinatus in 0% grip strength (p<0.05). In addition, it did not show a significant difference between muscles in 30%, 50% hand strength. Conclusions: This study showed an increase in shoulder muscle activation with increasing hand grip strength with the upper trapezius muscle being more activated than other muscles in 0% grip strength. The finding of this study suggests usefulness for development of preventative measures and rehabilitation strategies for increasing shoulder motor function in patients with breast cancer.

  • Objective : The zero-profile implant (Zero-P) is accepted for use in anterior cervical fusion for the treatment of degenerative cervical disease. However, evidence pertaining to its efficiency and safety in traumatic cervical injury is largely insufficient. This study aimed to compare the overall outcomes of patients who underwent Zero-P for traumatic cervical disc injury. Methods : Data from a total of 53 consecutive patients who underwent surgery for traumatic or degenerative cervical disc disease using the Zero-P were reviewed. Seventeen patients (group A) had traumatic cervical disc injury and the remaining 36 (group B) had degenerative cervical disc herniation. The fusion and subsidence rates and Cobb angle were measured retrospectively from plain radiographs. The patients' clinical outcomes were evaluated using the Japanese Orthopedic Association (JOA) score and Odom's criteria. Results : The C2-7 Cobb and operative segmental angles increased by $3.45{\pm}7.61$ and $2.94{\pm}4.59$ in group A; and $2.46{\pm}7.31$ and $2.88{\pm}5.49$ in group B over 12 postoperative months, respectively. The subsidence and fusion rate was 35.0% and 95.0% in group A; and 36.6% and 95.1% in group B, respectively. None of the parameters differed significantly between groups. The clinical outcomes were similar in both groups in terms of increasing the JOA score and producing a grade higher than "good" using Odom's criteria. Conclusion : The application of Zero-P in patients with traumatic cervical disc injury was found to be acceptable when compared with the clinical and radiological outcomes of degenerative cervical spondylosis.

  • Objective : The most common complication of anterior cervical discectomy and fusion (ACDF) is cage subsidence and maintenance of disc height affects postoperative clinical outcomes. We considered cage subsidence as an inappropriate indicator for evaluating preservation of disc height. Thus, this study aimed to consider patients with complications such as reduced total disc height compared to that before surgery and evaluate the relevance of several factors before ACDF. Methods : We retrospectively reviewed the medical records of 40 patients who underwent stand-alone single-level ACDF using a polyetheretherketone (PEEK) cage at our institution between January 2012 and December 2018. Our study population comprised 19 male and 21 female patients aged 24-70 years. The minimum follow-up period was 1 year. Twenty-seven patients had preoperative bone mineral density (BMD) data on dual-energy X-ray absorptiometry. Clinical parameters included sex, age, body mass index, smoking history, and prior medical history. Radiologic parameters included the C2-7 cobb angle, segmental angle, sagittal vertical axis, disc height, and total intervertebral height (TIH) at the preoperative and postoperative periods. Cage decrement was defined as the reduction in TIH at the 6-month follow-up compared to preoperative TIH. To evaluate the bone quality, Hounsfield unit (HU) value was calculated in the axial and sagittal images of conventional computed tomography. Results : Lumbar BMD values and cervical HU values were significantly correlated (r=0.733, p<0.001). We divided the patients into two groups based on cage decrement, and 47.5% of the total patients were regarded as cage decrement. There were statistically significant differences in the parameters of measuring the HU value of the vertebra and intraoperative distraction between the two groups. Using these identified factors, we performed a receiver operating characteristic (ROC) curve analysis. Based on the ROC curve, the cut-off point was 530 at the HU value of the upper cortical and cancellous vertebrae (p=0.014; area under the curve [AUC], 0.727; sensitivity, 94.7%; specificity, 42.9%) and 22.41 at intraoperative distraction (p=0.017; AUC, 0.722; sensitivity, 85.7%; specificity, 57.9%). Using this value, we converted these parameters into a bifurcated variable and assessed the multinomial regression analysis to evaluate the risk factors for cage decrement in ACDF. Intraoperative distraction and HU value of the upper vertebral body were independent factors of postoperative subsidence. Conclusion : Insufficient intraoperative distraction and low HU value showed a strong relationship with postoperative intervertebral height reduction following single stand-alone PEEK cage ACDF.

  • 배경: 유전자 치료에 의한 치료적 혈관조성은 허혈성 심질환의 새로운 치료전략의 하나로 최근 많은 연구가 진행되고 있다. 본 연구의 목적은 대동물에서 pCK 플라스미드 벡터에 혈관내피성장인자(vascular endothelial growth factor isoform 165: VEGF165) 유전자를 삽입한 pCK-VEGF를 이용한 치료적 혈관조성의 효용성을 증명하는 것이다. 대상 및 방법: 총 21 마리의 돼지를 이용하여 좌전하행지동맥의 원위부를 결찰하여 심근경색 모델을 만든 후, 4주 후에 VEGF 유전자를 삽입한 플라스미드를 심근내에 주입하거나(VEGF군), 유전자 없이 플라스미드 만을 주입하였다(대조군). 실험 대상 동물군을 맹검하에 무작위로 VEGF군 및 대조군으로 나누어 실험을 진행하였는데, 7마리는 실험 도중 사망하였으며 결과적으로 VEGF군은 8마리, 대조군은 6마리가 최종분석에 이용되었다. 좌전하행지동맥 결찰 후 30일째에 심근 SPECT와 심장초음파검사를 시행하고 심근내에 플라스미드를 주입하였으며, 이로부터 30일째에 심근 SPECT와 심장초음파검사를 다시 시행하였다. 허혈부위의 심근관류의 변화는 심근 SPECT상의 $^{99m}Tc-MIBI$의 섭취 정도로 비교하였으며, 국소 및 전체 심근기능 및 심실리모델링 등은 심장초음파 또는 게이트SPECT 검사상의 수축시 심실벽비후화, 좌심실구출률(EF), 수축기말용적(ESV), 이완기말용적(EDV) 등으로 비교하였다. 혈관조성의 정도는 조직검사상의 미세혈관의 밀도를 측정하여 비교하였다. 결과: 미세혈관의 밀도는 VEGF군에서 유의하게 더 높았으며($386\pm110/mm^{2}\;vs.\;291\pm127/mm^{2},\;p<0.001$), 분절의 관류 정도도 VEGF군에서는 관상동맥 결찰 60일째가 30일째에 비해 더 증가한 반면(플라스미드 주입 전, 후, $48.4\pm15.2\%\;vs.\;53.8\pm19.6\%,\;p<0.001$) 대조군에서는 유의한 변화가 없었고(플라스미드 주입 전, 후, $45.1\pm17.0\%\;vs.\;43.4\pm17.7\%,\;p=0.186$), 그 변화량도 두 군간에 유의한 차이를 보였다($11.4\pm27.0\%$ 증가 vs $2.7\pm19.0\%$ 감소, p=0.003). 수축시의 심실벽비후화는 양 군 모두에서 플라스미드 주입 후 유의하게 증가하였으나 증가한 정도는 두 군간에 차이가 없었다. 심장초음파검사상 ESV은 양 군 모두에서 수술 전에 비해 관상동맥 결찰 후 유의하게 증가하였고 (VEGF군, $22.9\pm9.9\;mL\;vs.\;32.3\pm9.1\;mL,\;p=0.006;$ 대조군, $26.3\pm12.0\;mL\;vs.\;36.8\pm9.7\;mL,\;p=0.046$), EF은 유의하게 감소하였으며(VEGF군, $52.0\pm7.9\%\;vs\;46.5\pm7.4\%$, p=0.004; 대조군, $48.2\pm9.2\%\;vs\;41.6\pm10.0\%$, p=0.028), EDV은 양 군 모두에서 유의한 변화가 없었다. 플라스미드 주입 전과 후의 비교에서는 양 군 모두에서 심장초음파 및 게이트 SPECT검사상의 EF, ESV, EDV 값의 유의한 차이가 없었다. 결론: VEGF165 유전자를 삽입한 플라스미드의 심근내 주입 후 허혈성 생존 심근 부위에 혈관조성이 일어나고 심근관류가 유의하게 증가하였다. 그러나 심근 기능이나 좌심실의 리모델링 경과엔 유의한 차이가 없었다.
