Use of resorbable mesh and fibrin glue for restoration in comminuted fracture of anterior maxillary wall

양재혁,장석주,신진용,노시균,이내호 대한두개안면성형외과학회 2018 Archives of Craniofacial Surgery Vol.19 No.3

Background: The facial bone has a complex structure compared to other bones, and various types of fractures can occur due to its characteristics. Among them, in comminuted fractures of anterior maxillary wall, multiple depressed and impacted bony segments cannot be reduced easily when performing internal fixation using plates and screws or wires, and inadequate restoration leads to a range of complications. This paper introduces an alternative technique using a resorbable mesh with fibrin glue to restore comminuted fractures of anterior maxillary wall. Methods: Thirteen patients were diagnosed with comminuted fractures of anterior maxillary wall between March 2017 and February 2018 in the authors’ hospital. All patients with comminuted fractures of anterior maxillary wall underwent restoration using resorbable mesh with fibrin glue. The patients’ demographics, causes of facial trauma, mean operation time, length of hospital stay, follow-up period, and complications were recorded. Results: No major complications and only one hypoesthesia of the skin area was noted. Three months after surgery, the hypoesthesia recovered completely. After surgery (mean, 3.9 months; range, 2.12 months), computed tomography showed that the bone fragments in all patients were fixed successfully in their anatomical places. Conclusion: In comminuted fractures of anterior maxillary wall, the use of a resorbable mesh with fibrin glue can be an advantageous and effective method for a successful restoration without complications.

육성 중인 Thoroughbred 망아지에서 희맹장 중첩 1례

An acute colic in a 6-month-old Thoroughbred filly is described. The filly was presented with acute colic characterized by rolling and pawing. Over a period of days she suffered from severe abdominal pain and subsequently died. Post mortem examination revealed the ileocecal intussusception as a part invagination of the ileum into the cecum. It seems logical to assume that the invagination occurred at the start of the illness. In addition, it is also noted the presence of Parascaris equorum in the stomach.

외측 반월상 연골 재이식술 후 발생한 양동이형 파열 - 증례 보고 -

반월상 연골 이식술은 젊은 환자에서 반월상 연골 제거술을 받은 환자에서 권장할 만한 술식으로 받아들여지고 있다. 그러나 수술 후 발생하는 합병증으로 인하여 임상결과가 제한 받을 수 있다. 반월상 연골 이식술 후 가장 흔한 합병증은 이식 연골의 파열이다. 술 후 양동이형 파열의 발생은 드물며, 반월상 재이식술 후 양동이형 파열은 더욱 보고가 드물다. 저자들은 외측 반월상 재 이식술 후 양동이형 파열을 경험하였으며, 후향적 조사상 양동이형 파열에 대해 원인을 규명할 수 있었으며, 이를 근거로 재발 방지에 대한 방법을 모색하고자 한다. Meniscal allograft transplantation (MAT) is an accepted treatment for the symptomatic postmeniscectomized knee in younger patients. However, the likelihood of a successful outcome is reduced by various complications. One of the complications after MAT is manifested as grafted meniscal tear. However, a bucket handle meniscal tear (BHMT) following MAT is an uncommon complication and furthermore a BHMT after revisional MAT (RMAT) is a extremely rare complication. We encountered a case of BHMT after RMAT in a lateral meniscus. Retrospectively reviewing the case, we could assume the cause, which would be helpful to prevent the complication in further MAT procedures.

Volume and Contact Surface Area Analysis of Bony Tunnels in Single and Double Bundle Anterior Cruciate Ligament Reconstruction Using Autograft Tendons: In Vivo Three-Dimensional Imaging Analysis

양재혁,장민호,곽대순,왕준호 대한정형외과학회 2014 Clinics in Orthopedic Surgery Vol.6 No.3

Background: Regarding reconstruction surgery of the anterior cruciate ligament (ACL), there is still a debate whether to perform a single bundle (SB) or double bundle (DB) reconstruction. The purpose of this study was to analyze and compare the volume and surface area of femoral and tibial tunnels during transtibial SB versus transportal DB ACL reconstruction. Methods: A consecutive series of 26 patients who underwent trantibial SB ACL reconstruction and 27 patients with transportal DB ACL reconstruction using hamstring autograft from January 2010 to October 2010 were included in this study. Three-dimensional computed tomography (3D-CT) was taken within one week after operation. The CT bone images were segmented with use of Mimics software v14.0. The obtained digital images were then imported in the commercial package Geomagic Studio v10.0 and SketchUp Pro v8.0 for processing. The femoral and tibial tunnel lengths, diameters, volumes and surface areas were evaluated. A comparison between the two groups was performed using the independent-samples t-test. A p-value less than the significance value of 5% (p < 0.05) was considered statistically significant. Results: Regarding femur tunnels, a significant difference was not found between the tunnel volume for SB technique (1,496.51 ± 396.72 mm3) and the total tunnel volume for DB technique (1,593.81 ± 469.42 mm3; p = 0.366). However, the total surface area for femoral tunnels was larger in DB technique (919.65 ± 201.79 mm2) compared to SB technique (810.02 ± 117.98 mm2; p = 0.004). For tibia tunnels, there was a significant difference between tunnel volume for the SB technique (2,070.43 ± 565.07 mm3) and the total tunnel volume for the DB technique (2,681.93 ± 668.09 mm3; p ≤ 0.001). The tibial tunnel surface area for the SB technique (958.84 ± 147.50 mm2) was smaller than the total tunnel surface area for the DB technique (1,493.31 ± 220.79 mm2; p ≤ 0.001). Conclusions: Although the total femoral tunnel volume was similar between two techniques, the total surface area was larger in the DB technique. For the tibia, both total tunnel volume and the surface area were larger in DB technique.

Frost shattering has traditionally been considered as one of the most effective process in rock weathering. Each slab specimens of five or six rhyolite, basalt and tuff was prepared and put in freeze-thaw cycles and repeated 300 times in the temperature of -25°C to +30°C and their weathering patterns and products were analyzed by surface observation, particle size, XRD and thin section. As the result, some changes were observed in weathering patterns and weathering products. Rock shattering was more active in waterlogging rather than atmospheric conditions, but there are many differences depending on the type of rock. Rhyolite is hardly weathered by 300 times freeze-thaw cycles and generates the least amount of weathering products. Weathering of Basalt is limited to the surface layer where water can be absorbed, and produces a few amount of platy-shape debris. Tuff are separated by blocky structure which the particles are aggregated along their edges rather than enlarged existing cracks/joins or generated new joints.

본 연구는 초등학생들의 기본욕구, 사회성, 학교생활적응의 실태를 알아보고, 기본욕구와 사회성이 학교생활적응에 미치는 효과를 알아보기 위하여 실시하였다. 연구 참가자들은 554명의 초등학생들 이었다. 연구의 결과는 다음과 같다. 첫째, 소속욕구와 재미욕구, 성취욕구가 남녀학생 간에 의미 있 는 차이를 나타냈다. 둘째, 생존욕구는 수업활동과, 소속욕구는 생활전반과, 성취욕구와 재미욕구는 지배성과 정적상관을 보였다. 셋째, 생존욕구, 소속욕구, 성취욕구, 재미욕구가 높을수록 학교생활적 응에 정적영향을, 자유욕구는 높을수록 부적영향을 주는 것으로 나타났다. 사회성은 활동성, 안정성, 자율성과 사교성이 높을수록 학교생활적응에 정적영향을 주는 것으로 나타났다. This study aimed to examine the status of elementary students’ basic needs, sociality, and school life adaptation, and investigate the efficacy of basic needs and sociality on school life adaptation. The participants were 554 elementary school students. The results were as follows. First, there was a significant difference between genders in terms of belonging need, fun need, and achievement need. Second, survival need showed a positive relationship with classroom activity, belonging need with life in general, and achievement need and fun need with dominance. Third, the higher survival, belonging, and fun needs, the more positive effect for school life adaptation. The higher fun need, the more negative effect. As for sociality, it was revealed that with the higher activity, stability, autonomy, and sociability, the better positive effect on school life adaptation was observed.

In recent years, the drying of the water spider habitat has been progressing rapidly. This is the primary cause of extreme climatic events in 2014/2015 with overall reduction in annual precipitation, but impermeable clayey layer formed in the superficial formation also plays an important role. The clayey layer is a critical factor in the formation of wetlands on a well-drained lava plateau, but paradoxically, it restricts the connection with ground water, increasing the instability of the water balance and making it precipitation-dependent structure. In addition, construction of roads/drainways has also caused drying of wetlands by blocking or rapidly spilling surface water/sheet flow. Therefore, to keep the wetlands sustainable, it should increase the flow into the wetlands by removing the road/drainways and floodgates installed to reduce the outflow.
