A rare case report of vulvar necrotizing fasciitis in a healthy patient

IntroductionNecrotizing fasciitis (NF), a necrotizing infection of the soft tissue, is a medical emergency usually occurring in the lower extremities and abdominal regions and often difficult to diagnose promptly.Presentation of caseThis case report looks at one atypical presentation of NF with the unusual location of the vulva and no known associated comorbidities or risk factors.DiscussionDiagnosing this patient was particularly difficult due to the inconsistent clinical, laboratory and imaging findings. The CT scans and WBC count were indicative of NF, but the LRINEC score was not high enough to make the diagnosis of NF. As a result, we relied on the hemodynamic instability and clinical findings of the physical exam to be strong indicators of NF, and acted on that indication.ConclusionActing quickly on the hemodynamic findings and suspicion as opposed to waiting for a confirmed diagnosis resulted in a good prognosis since immediate surgical debridement is imperative to surviving this acute condition. Despite major advancements in the imaging modalities and the introduction of a laboratory score, our case suggests that the diagnosis still heavily relies on clinical findings, such as hemodynamic instability. Furthermore, our case suggests that NF should be included in the differential regardless of atypical location and lack of common clinical associations.     

Two giant peritoneal loose bodies were simultaneously found in one patient: A case report and review of the literature

IntroductionPeritoneal loose body(PLB) is usually small, therefore giant Peritoneal loose body(gPLB) with a diameter >5 cm has rarely been described in the literatures. We report a case of two gPLB simultaneously found in one patient.Presentation of caseA healthy 79-year-old man palpated himself a solid mass with alternating localizations in his peritoneal cavity 6 months ago. It was not the complaint of frequency of urinatior until he saw the doctor a week ago. Surprisingly, two oval-shaped masses were simultaneously discovered by computed tomography (CT). One was in the peritoneal cavity, measuring 10.4*8.3 cm, weight 182.5 g, another was in the pelvic cavity, measuring 7.6*6.0 cm, weight 98.4 g. The case was confirmed by surgical operation.DiscussionThe gPLB is considered as uncommon. Two gPLB which were simultaneously discovered in one patient have never been reported in the literatures. The small PLB is usually asmptomatic, occasionally, the gPLB can cause symptoms with acute retention of urine or intestinal obstruction. It is crucial to diagnosis the peritoneal loose body.ConclusionTwo gPLB that situated in one patient are rare findings. Clinically, if a solid mass alternating localizations cound be palpated in the Peritoneal cavity, CT or other imaging shows an oval-shaped mass with calcifications in the central region, PLB should be considered. Surgical removal is recommended for the patient with acute retention of urine or intestinal obstruction or unclear diagnosis.     

Development and multicenter validation of a nomogram for preoperative prediction of lymph node positivity in pancreatic cancer(NeoPangram)

Background: Neoadjuvant therapy is associated with nodal downstaging and improved oncological outcomes in patients with lymph node(LN)-positive pancreatic cancer. This study aimed to develop and validate a nomogram to preoperatively predict LN-positive disease. Methods: A total of 558 patients with resected pancreatic cancer were randomly and equally divided into development and internal validation cohorts. Multivariate logistic regression analysis was used to construct the nomogram. Model performance was evaluated by discrimination, calibration, and clinical usefulness. An independent multicenter cohort consisting of 250 patients was used for external validation. Results: A four-marker signature was built consisting of carbohydrate antigen 19–9(CA19–9), CA125, CA50, and CA242. A nomogram was constructed to predict LN metastasis using three predictors identified by multivariate analysis: risk score of the four-marker signature, computed tomography-reported LN status, and clinical tumor stage. The prediction model exhibited good discrimination ability, with C-indexes of 0.806, 0.742 and 0.763 for the development, internal validation, and external validation cohorts, respectively. The model also showed good calibration and clinical usefulness. A cut-off value(0.72) for the probability of LN metastasis was determined to separate low-risk and high-risk patients. Kaplan-Meier survival analysis revealed a good agreement of the survival curves between the nomogram-predicted status and the true LN status. Conclusions: This nomogram enables the identification of pancreatic cancer patients at high risk for LN positivity who may have more advanced disease and thus could potentially benefit from neoadjuvant therapy.     

峡部入路与上外侧入路方法在改良Miccoli手术中的临床应用

目的：探讨峡部入路方法在改良Miccoli手术中应用的效果。方法选择2013年2月~2014年10月抚顺市中心医院收治的行改良Miccoli手术的56例良性甲状腺疾病患者,将其分为峡部入路组(n =30)与上外侧入路组(n=26),由同一手术组人员完成手术,比较不同入路方法患者手术时间、手术出血量、术后24 h引流量以及术后住院时间的差异。结果55例患者成功行改良Miccoli手术,上外侧入路组中1例患者术中出血中转开放手术,1例患者出现暂时性声音嘶哑,其余患者未见声音嘶哑、饮水呛咳、手足抽搐等严重并发症。峡部入路组和上外侧入路组的手术时间、手术出血量及术后24 h引流量比较差异有统计学意义(P约0.05),术后住院时间比较差异无统计学意义(P跃0.05)。结论峡部入路方法应用在改良Miccoli手术中可缩短手术时间,减少手术出血量及术后引流量,值得临床推广。
