Background: As the population is aging and indications are expanding, shoulder arthroplasty is becoming more frequent, especially bilateral staged replacement. However, surgeons are hesitant to use bilateral reverse prostheses due to potential limitations on activities of daily living. Methods: This meta-analysis was conducted to compare bilateral anatomic to bilateral reverse shoulder implants. PubMed, Cochrane, and Google Scholar (pages 1-20) were searched until April 2023. The clinical outcomes consisted of postoperative functional scores (American Shoulder and Elbow Surgeons [ASES], Single Assessment Numeric Evaluation [SANE], Physical Component Score [PCS], Mental Component Score, and Simple Shoulder Test), pain, and range of motion (external rotation and forward elevation). Three studies were included in this meta-analysis. Results: Bilateral anatomic implants had better postoperative functional outcomes and range of motion, but no significant difference was seen in postoperative pain when compared to the reverse prosthesis. Better ASES score, SANE score, and PCS as well as better external rotation and forward elevation were seen in the bilateral anatomic shoulder replacement group, but no significant difference in pain levels was seen between the two groups Conclusions: The results may be explained by the lower baseline seen in the reverse prosthesis group, which may be due to an older population and different indications. Nevertheless, more randomized controlled studies are needed to confirm these findings. Level of evidence: III.

Midline clefts of the upper lip are rare, and it is therefore important that surgeons have access to a methodical approach for when these presentations are encountered. We adapted principles of the anatomic subunit approximation for unilateral cleft lip, to the repair of midline clefts. The overt use of anatomic landmarks to define the repair results in a design that inherently adjusts to varying degrees of clefts and can accommodate asymmetries. The "measure twice, cut once" style is an advantage to new surgeons and to surgeons who seldom encounter this presentation. We describe the details of surgical repair in the context of a patient with Pai syndrome and associated nasal hamartomas that resulted in nasolabial asymmetry. This is the first report of surgical outcome following treatment of Pai syndrome and includes early and 5-year follow-up. The system of repair that we describe is applicable to both symmetric and asymmetric midline clefts.

Extra-anatomic bypass is indicated for the limb salvage of patients with threatened limb loss especially those who have high risk of infection and death after general anesthesia. We did extra-anatomic bypass procedure nineteen times over a seven year, two month period on sixteen patients. Their mean follow up period was 41.3 months. Male to female ratio was 7:1. Major complaints were resting pain[36.8%], claudication[31.6%], cyanosis[15.8%] and ulcerative change[15.8%]. Associated diseases were hypertension, tuberculosis, chronic renal failure, atrial fibrillation, complete heart block and laryngeal cancer. Postoperative patency rates were 76.9% at 1 year, 72.7% at 2 years and 70% at 3 years. Limb salvage rate was 78.9%. Postoperative mortality rate was 10.5%.

Double outlet right ventricle (DORV) is a relatively common congenital heart disease in which both great arteries are connected completely or predominantly to the morphologic RV. Unlike other congenital heart diseases, DORV demonstrates various anatomic and hemodynamic subtypes, mimicking ventricular septal defect, tetralogy of Fallot, transposition of the great arteries, and functional single ventricle. Because different surgical strategies are applied to different subtypes of DORV with ventricular septal defects, a detailed assessment of intracardiac anatomy should be performed preoperatively. Due to high spatial and contrast resolutions, cardiac CT can provide an accurate characterization of various intracardiac morphologic features of DORV. In this pictorial essay, major anatomic factors affecting surgical decision-making in DORV with ventricular septal defects were comprehensively reviewed using three-dimensional cardiac CT data. In addition, the surgical procedures available for these patients and major postoperative complications are described.

목적: 본 연구는 갈색세포종의 수술 전 초기 진단에서 MIBG 스캔이 생화학적 검사나 해부학적 영상, 각각의 진단방법과 이 두 가지 진단 방법을 함께 이용한 경우와 비교해서 어떠한 진단적 가치를 가질 수 있는지 평가하기 위해 진행되었다. 대상및방법: 환자군은 2004년 4월부터 2008년 4월까지 임상적으로 갈색세포종이 의심되어 본원에 내원한 총 22명의 환자(남:여=13:9, 평균나이: $44.3{\pm}\;19.3$세)를 대상으로 하였고, 환자들은 진단을 위해 생화학적 검사(24 시간 뇨의 VMA, 메타네프린, 뇨와 혈장의 에피네프린, 노르에피네프린)와 해부학적 영상검사(CT 또는 MRI), I-123/I-131 MIBG 스캔을 모두 시행하고 조직학적으로 최종 확진이 이루어졌다. 결과: 각각의 진단방법에 대한 예민도, 특이도, 양성예측율, 음성예측율, 정확도를 구하여 그 수치를 비교하였는데 결과적으로 생화학적 검사는 88.9%, 69.2%, 66.7%, 90.0%, 77.3%, 해부학적 영상은 55.6%, 69.2%, 55.6%, 69.2%, 63.6%로 나타났으며, 위의 두 검사를 함께 사용한 경우에는 88.9%, 61.5%, 50.0%, 83.3%, 59.1% 이었다. 이에 비해 I-123/I-131 MIBG스캔을 단독으로 사용한 경우는 88.9%, 92.3%, 88.9%, 92.3 %, 90.9%로 나와서 생화학적 검사와 해부학적 영상을 각각 이용한 경우의 결과와 비교하여 전반적으로 수치가 높았고, 두 가지 검사를 함께 사용한 경우와 비교해서도 특이도, 양성예측율, 음성예측율, 정확도는 높고 예민도는 같은 결과를 보인 것으로 나타났다. 결론: 따라서 갈색세포종의 수술 전 초기진단에 있어서 생화학적 검사나 해부학적 영상뿐만 아니라 MIBG 스캔도 단일 검사로써 충분히 유용한 진단적 가치를 가질 것으로 기대되며, MIBG의 기능적 영상정보에 CT의 해부학적 영상정보를 함께 융합할 수 있는 SPECT/CT나 교감신경계에 섭취될 수 있는 PET tracer를 이용한 PET/CT를 사용한다면 갈색세포종에 대한 진단 능력을 더욱 높일 수 있을 것이다.

Taxonomic relationships between some inulin containing plants such as Platycodon and Codonopsis have been investigated comparing their contents of inulin crystals, resin, as well as TLC patterns of saponins and acetylenes. Although Platycodon and Codonopsis have been known to be close in anatomic characters, the present results showed that there were significant differences between not only in the genus but also in the species.

The fine needle aspiration biopsy(FNAB) has become a popular method to diagnose mass lesions of the liver. Although many reports have listed FNAB criteria to be used to diagnose hepatocellular carcinoma(HCC), a diagnostic dilemma still exists at the extreme ends of the spectrum, particularly for well differentiated HCC. The authors reviewed a series of FNAB specimens of the liver to distinguish well differentiated HCC from nonneoplastic liver. Fifteen cytologic features were examined in this study: high cellularity, large sheet formation, trabecular pattern, acinar pattern, dispersed pattern, irregular arrangement, increased nuclear/cytoplasmic ratio, naked nuclei, irregular chromatin, irregular nuclear contour, multinucleation, uniform macronucleoli, multiple nuclei, uniform small cytoplasm and monotony of atypia. These features were examined in a series of 76 FNAB specimens. Fifty two specimens were from patients with HCC and 24 specimens were from patients with nonneoplastic lesion or tumors other than HCC containg adequate amount of nonneoplastic hepatocytes in smear. All specimens were coded as to the presence or absence of the above cytologic features. With the use of step-wise logistic regression analysis, three features were identified as the key cytologic features predictive of HCC: irregular chromatin, monotony of atypia and absence of large sheet formation. When these criteria were used, the sensitivity diagnosing HCC by FNAB was 94.2%, specificity 100%, positive predictive value 100% and negative predictive value was 88.9%.

Primary small cell carcinoma of the urinary bladder is a rare malignant tumor. A more rapidly fatal course may be seen in advanced stages of small cell carcinoma as compared to similar stages of urothelial carcinoma. It is very important to recognize this distinct form of bladder cancer by urinary cytology The differential diagnosis of small cell carcinoma of the urinary bladder includes metastatic small cell carcinoma, urothelial carcinoma, and primary or secondary malignant lymphoma. This article highlights the urinary cytologic diagnosis of a case of primary small cell carcinoma. A 59-year-old male presented with gross hematuria for five months. Urinary cytology showed high cellularity consisting of tiny monotonous tumor cells in the necrotic background. The tumor cells occurred predominantly singly, but a few in clusters. The cytoplasm was so scanty that only a very narrow rim of it was seen. The nuclei were oval or round and had finely stippled chromatin. Rarely, the nuclei contain visible nucleoli. Frequently cell molding was noted in clusters. Many single cells demonstrated nuclear pyknosis or karyorrhexis. The histologic findings of transurethral resection and partial cystectomy specimen were those of small cell carcinoma. Cytologic distinction may be very difficult but careful attention to clinical features and cellualr details can classify these neoplasms correctly.
