BackgroundHepatoid adenocarcinoma of the stomach (HAS) is a rare type of gastric cancer, but the role of perioperative chemotherapy is still poorly understood. The aim of this retrospective study was to investigate the associations between perioperative chemotherapy and prognosis of HAS.MethodWe retrospectively analyzed patients with locally advanced HAS who received radical surgery in Peking University Cancer Hospital between November 2009 and October 2020. Patients were divided into neoadjuvant chemotherapy-first (NAC-first) group and surgery-first group. The relationships between perioperative chemotherapy and prognosis of HAS were analyzed using univariate, multivariate survival analyses and propensity score matching analysis (PSM).ResultsA total of 100 patients were included for analysis, including 29 in the NAC-first group and 71 in the surgery-first group. The Her-2 amplification in HAS patients was 22.89% (19/83). For NAC-first group, 4 patients were diagnosed as tumor recession grade 1 (TRG1), 4 patients as TRG 2, and 19 patients as TRG 3. No significant difference in prognosis between the surgery-first group and the NAC-first group (P=0.108) was found using PSM analysis. In the surgery-first group, we found that the survival rate was better in group of ≥6 cycles of adjuvant chemotherapy than that of <6 cycles (P=0.013).ConclusionNAC based on platinum and fluorouracil may not improve the Overall survival (OS) and Disease-free survival time (DFS) of patients with locally advanced HAS. Patients who received ≥6 cycles of adjuvant chemotherapy had better survival. Therefore, the combination treatment of radical gastrectomy and sufficient adjuvant chemotherapy is recommended for patients with locally advanced HAS.

Purpose: The purpose of the study is to analyze the results of surgical treatment of patients with brain and torso injury for 5 years in a single regional trauma center.Methods: We analyzed multiple trauma patients who underwent brain surgery and torso surgery for chest or abdominal injury simultaneously or sequentially among all 14,175 trauma patients who visited Dankook University Hospital Regional Trauma Center from January 2015 to December 2019.Results: A total of 25 patients underwent brain surgery and chest or abdominal surgery, with an average age of 55.4 years, 17 men and eight women. As a result of surgical treatment, there were 14 patients who underwent the surgery on the same day (resuscitative surgery), of which five patients underwent surgery simultaneously, four patients underwent brain surgery first, and one patient underwent chest surgery first, four patients underwent abdominal surgery first. Among the 25 treated patients, the 10 patients died, which the cause of death was five severe brain injuries and four hemorrhagic shocks.Conclusions: In multiple damaged patients require both torso surgery and head surgery, poor prognosis was associated with low initial Glasgow Coma Scale and high Injury Severity Score. On the other hand, patients had good prognosis when blood pressure was maintained and operation for traumatic brain injury was performed first. At the same time, patients who had operation on head and torso simultaneously had extremely low survival rates. This may be associated with secondary brain injury due to low perfusion pressure or continuous hypotension and the traumatic coagulopathy caused by massive bleeding.

AbstractOrthodontic-surgical treatment with the “Surgery First Approach” provides immediate facial aesthetic improvements and significantly reduces the patient's orthodontic treatment time, avoiding the transient worsening of the facial profile due to dental decompensation that occurs in surgical cases. Thus, this clinical case describes the retreatment of a 22-year-old female leukoderma patient, whose main complaint was related to the proclination of upper and lower incisors. The patient used a mio-relaxing plate for 30 days, which evidenced the skeletal mandibular deficiency and the ½ bilateral Class II malocclusion. Orthognathic surgery first approach associated with the extraction of the 4 premolars was chosen considering the patient’s aesthetic demand. The use of a mio-relaxing plate in the diagnostic stage was essential for the real diagnosis of mandibular deficiency and the technique employed made it possible to conclude the treatment avoiding aesthetic commitment, with excellent results. Keywords: Malocclusion, Angle Class II. Orthognathic Surgery. Orthodontics, Corrective. ResumoO tratamento ortodôntico-cirúrgico por meio do benefício antecipado proporciona melhorias estéticas faciais imediatas e reduz de maneira significativa o tempo de tratamento ortodôntico do paciente, evitando a piora transitória do perfil facial devido à descompensação dentária que ocorre em casos cirúrgicos. Assim, este caso clínico descreve o retratamento de uma paciente com 22 anos de idade, leucoderma, sexo feminino, que apresentava queixa principal relacionada à inclinação vestibular dos dentes anteriores. Após uso de placa miorrelaxante por 30 dias, verificou-se a presença de Classe II esquelética com deficiência mandibular e ½ Classe II dentária bilateral. Considerando a demanda estética da paciente, optou-se pela abordagem ortodôntico-cirúrgica com Benefício Antecipado associada à extração de 4 pré-molares para correção da inclinação dentária anterior. O uso da placa miorrelaxante foi fundamental para o diagnóstico real da deficiência mandibular e a técnica empregada possibilitou concluir o tratamento evitando o comprometimento estético pré-cirúrgico, com obtenção de excelentes resultados.

Abstract Background This study aimed to assess the accuracy of virtual surgical planning (VSP) in segmental osteotomy in combination with bimaxillary orthognathic surgery with surgery first approach (SFA) by means of three-dimensional (3D) measuring and superimposition, so as to promote the application of digital technology in combined orthodontic-orthognathic treatment. Methods 20 patients treated with segmental osteotomy in combination with bimaxillary orthognathic surgery with SFA from 2018 to 2020 were included. All of them acquired VSP performed by ProPlan CMF 3.0 software (Materialise Corporation, Belgium). The preoperative (T0) 3D model of VSP and the postoperative (T1) 3D model, reconstructed by the cone-beam computed tomography (CBCT) data acquired one week after surgery, were compared by measuring the 3D coordinates of the landmarks as well as 3D model superimposition for deviation analysis. The deviation analysis was achieved by Geomagic Studio 2013 (3D Systems Corporation, USA). The differences which represented the accuracy of VSP were evaluated by the root mean square deviation (RMSD) and the Bland–Altman method. Results There was no statistically significant difference between the 3D coordinates of T1 and T0 (P > 0.05), and the mean overall RMSD was 1.37 mm, within the clinical relevance of 2 mm. The RMSD of sagittal direction (1.76 mm) was greater than that of coronal and vertical directions (1.09 mm and 1.24 mm), and the RMSD of maxillary and mandibular aspects were basically equal (1.30 mm and 1.45 mm). The Bland–Altman method showed the T0 and T1 measurements were in good agreement. The mean RMSD obtained from the deviation analysis was 1.85 mm, within the clinical relevance. Conclusions VSP in segmental osteotomy in combination with bimaxillary orthognathic surgery with SFA proved to acquire accurate outcome in this study.
