    尽管产科护理取得了进展,产后子痫仍然是母亲发病和死亡的主要原因.尽管产后阶段子痫的最常见治疗方法是硫酸镁(MgSO4),一小部分人对这种方法表现出抵抗力。临床挑战来自MgSO4耐药性,这要求采取不同的护理方法,以避免对母亲不利的后果。在这个案例研究中,我们对一名19岁的primigravida进行了全面的临床描述,他在37周时分娩,出现了产后子痫,经MgSO4治疗后未好转.因此,此案例凸显了对患者进行准确临床诊断和迅速使用替代疗法的重要性。我们还讨论了治疗这种罕见但严重疾病的可能方法。
    Despite advances in obstetric care, postpartum eclampsia continues to be a major cause of morbidity and mortality among mothers. Although the most common treatment for eclampsia during the postpartum phase is magnesium sulfate (MgSO4), a small percentage of individuals show resistance to this approach. Clinical challenges arise from MgSO4 resistance, which calls for different approaches to care to avoid unfavorable consequences for mothers. In this case study, we provide a thorough clinical description of a 19-year-old primigravida who gave birth at 37 weeks and developed postpartum eclampsia and did not improve with MgSO4 treatment. This case thus highlights the significance of accurate clinical diagnosis of patients and prompt use of alternative therapy modalities. We also discuss possible approaches to treating this uncommon but serious illness.

    MET外显子14跳跃突变(METex14s)很少被报道为EGFR酪氨酸激酶抑制剂(TKIs)的潜在耐药机制。针对奥希替尼耐药后出现的METex14s靶向治疗的疗效尚不确定。在这里,我们报道了一例EGFR突变的转移性肺腺癌,其中METex14在奥希替尼一线耐药后再次活检中被检出.患者接受卡马替尼单药治疗作为三线治疗,这是无效的,其次是对阿法替尼的抢救治疗的异常反应。该报告强调了EGFR-TKI耐药的异质性,靶向罕见的耐药机制仍然具有挑战性。
    MET exon14 skipping mutations (METex14s) are rarely reported as a potential resistance mechanism to EGFR tyrosine kinase inhibitors (TKIs). The efficacy of targeted therapy against METex14s emerging after osimertinib resistance is uncertain. Herein, we report a case of EGFR-mutated metastatic lung adenocarcinoma in which METex14 was detected in a re-biopsy upon first-line osimertinib resistance. The patient received capmatinib monotherapy as third-line therapy, which was ineffective, followed by an exceptional response to salvage therapy with afatinib. This report highlights the heterogeneity of EGFR-TKI resistance and that targeting rare resistance mechanisms remains challenging.

    分析培训期间案例撰写过程的教育和临床效果尚未得到广泛研究,即使病例报告,作为一个产品,促使人们试图使其成为一个更有启发性和更准确的文件。分析过程中的反移情经历会限制候选人的写作和分析工作,而在写作过程中检查它们可以加深候选人的分析工作。三个重叠的书写阻力,以及他们潜在的焦虑,被描述。这些是出版阻力:对潜在批判性读者预期接受候选人作品的担忧;移情阻力:对需要写作的分析机构的感受;和反移情或重新沉浸阻力:担心分析会重新唤醒反应。这些可能会干扰找到要写入的安全内部空间。给出了在案件监督期间通过这些阻力进行写作的例子,导致更开放的写作和分析工作的深化。由于案例撰写过程可能对候选人当前和未来的分析工作产生直接和潜在的深远影响,建议案例撰写过程是分析培训的第四支柱,除了候选人的个人分析,案件监督,和说教研讨会。
    The educational and clinical effects of the process of case writing during analytic training have not been extensively studied, even though the case report, as a product, has prompted attempts to make it a more revealing and accurate document. Countertransference experiences during an analysis can constrain both the candidate\'s writing and the analytic work, while examining them during the writing process can deepen the candidate\'s analytic work. Three overlapping resistances to the writing, and their underlying anxieties, are described. These are publication resistances: concerns about the anticipated reception of the candidate\'s work by potentially critical readers; transference resistances: feelings toward the analytic institute that requires the writing; and countertransference or reimmersion resistances: fears of reawakening reactions from the analysis. These can interfere with finding a safe internal space in which to write. Examples are given of writing through of these resistances during case supervision, resulting in more open writing and in a deepening of the analytic work. As the case writing process can have direct and potentially profound effects on the candidate\'s current and future analytic work, it is proposed that the process of case writing is a fourth pillar of analytic training, in addition to the candidate\'s personal analysis, case supervision, and didactic seminars.

    靶向化疗和免疫检查点抑制剂(ICPi)扩大了复发/难治性(r/r)霍奇金病患者的治疗范围,并显着提高了长期疾病控制患者的比例。然而,在进一步进展的情况下,没有标准化的治疗选择。最近,我们证明了MEPED(节拍化疗,依维莫司,吡格列酮,依托考昔,地塞米松)对r/r霍奇金病患者非常有效。尚未研究用ICPi预处理后的益处,yet.这里,我们报道了一例首次使用Pembrolizumab治疗的进展性霍奇金病患者,该患者在开始MEPED治疗后获得持续完全缓解(CR).一名57岁的患者接受本妥昔单抗vedotin治疗复发性晚期霍奇金病,并于2020年11月至2022年7月接受Pembrolizumab治疗进展。由于进一步发展,MEPED治疗于2022年8月开始,一直持续到2023年5月。它包括严格口服每日(28天周期)250毫克的低剂量曲硫丹,依维莫司15毫克,吡格列酮45毫克,依托考昔60毫克,和地塞米松0.5mg。通过F-18FDG-PET/CT(PET/CT)评价治疗反应。CR由1-3的负Deauville评分(DS)定义。已经开始MEPED3个月后,aCR(DS:3)于2022年11月通过PET/CT确认。2023年5月的下一次随访继续显示CR(DS:3)。治疗耐受性很好。没有观察到血液学或其他器官毒性。然而,2023年5月,患者出现腿部水肿和体重增加,最有可能是由于吡格列酮和PET/CT显示疑似依维莫司诱导的肺炎,因此终止MEPED,开始利尿剂治疗和泼尼松龙治疗,并逐渐减量.这导致症状的快速完全解决。2023年7月的下一次PET-CT继续显示CR(DS:3),没有肺炎的证据。目前,MEPED治疗尚未恢复。总之,我们首次证明MEPED治疗对ICPi难治性霍奇金病患者非常有效。在MEPED治疗开始后超过11个月实现了持续CR。应该对更大的患者队列进行进一步的研究。
    Targeted chemotherapy and immune checkpoint inhibitors (ICPi) have expanded the spectrum of therapies for patients with relapsed/refractory (r/r) Hodgkin\'s disease and significantly improved the proportion of patients with long-term disease control. However, there is no standardized therapeutic option in case of further progression. Recently, we demonstrated that therapy with MEPED (metronomic chemotherapy, everolimus, pioglitazone, etoricoxib, dexamethasone) is highly effective in patients with r/r Hodgkin\'s disease. The benefit after pre-treatment with ICPi has not been studied, yet. Here, we report a patient with progressive Hodgkin\'s disease on Pembrolizumab for the first time who achieved sustained complete remission (CR) after initiation of MEPED therapy. A 57-year-old patient was pre-treated with brentuximab vedotin for relapsed advanced Hodgkin\'s disease and had received Pembrolizumab for progression from November 2020 to July 2022. Due to further progression, MEPED therapy was started in August 2022 and continued until May 2023. It consisted of a strictly oral daily (28-day cycle) application of low-dose treosulfan 250 mg, everolimus 15 mg, pioglitazone 45 mg, etoricoxib 60 mg, and dexamethasone 0.5 mg. Treatment response was evaluated by F-18 FDG-PET/CT (PET/CT). CR was defined by a negative Deauville score (DS) of 1-3. Already 3 months after starting MEPED, a CR (DS: 3) was confirmed by PET/CT in November 2022. The next follow-up in May 2023 continued to show CR (DS: 3). The therapy was very well tolerated. No hematological or other organ toxicity was observed. However, in May 2023 the patient presented with leg edema and weight gain, most likely due to pioglitazone and the PET/CT revealed suspected everolimus-induced pneumonitis, so MEPED was discontinued and diuretic therapy and treatment with prednisolone was started with gradual dose reduction. This resulted in a rapid complete resolution of the symptoms. The next PET-CT in July 2023 continued to show CR (DS: 3) without evidence of pneumonitis. Currently, therapy with MEPED has not been resumed. In conclusion, we demonstrate for the first time that MEPED therapy is highly effective in a patient with Hodgkin\'s disease who has been refractory to ICPi. Sustained CR was achieved over 11 months after initiation of MEPED therapy. Further studies on a larger patient cohort should be performed.

    佐剂奥希替尼代表了切除的EGFR突变肺癌的管理的最新范式转变。奥希替尼辅助治疗3年后复发的患者的最佳后续治疗尚不清楚。这里,我们报告了两例奥希替尼再次攻击完全缓解的病例,这些病例是以前使用奥希替尼辅助治疗后复发的结果,以及缺乏获得性抗性机制的系列分子小组。有必要进行未来的前瞻性研究,以确认先前使用奥希替尼辅助治疗后复发的患者的最佳治疗方法。
    Adjuvant osimertinib represents a recent paradigm shift in the management of resected EGFR-mutated lung cancer. The optimal subsequent treatment of patients who relapse after completion of 3 years of adjuvant osimertinib is unknown. Here, we report two cases of complete response to osimertinib rechallenge after relapse from previous adjuvant osimertinib use, and a serial molecular panel exhibiting a lack of acquired resistance mechanisms. Future prospective studies are warranted to confirm the optimal treatment of patients who relapse after previous adjuvant osimertinib.

    这项研究考察了女性对男性强奸案件中受害者和肇事者的归因以及受三个受害者相关变量影响的事件严重程度归因:先前的性受害,强奸期间的抵抗,强奸期间的性唤起。在确定将责任归于受害者和犯罪者以及将严重程度归于事件时,它评估了这些变量中每个变量的相对权重。研究发现,性唤起和缺乏抵抗与较高的受害者归因相关,较低的肇事者责任,和较低的事件严重程度归因,而之前的性受害具有相反的相关性。因此,我们得出的结论是,在强奸之前和强奸期间,受害者的行为会影响责任和严重性归因。
    This study examines blame attributions of victims and perpetrators in female-on-male rape cases and event severity attributions as affected by three victim-related variables: prior sexual victimization, resistance during the rape, and sexual arousal during the rape. It assesses the relative weight of each of these variables in determining the attribution of blame to the victim and perpetrator and the attribution of severity to the event. The study found that sexual arousal and absence of resistance correlated with higher victim blame attribution, lower perpetrator blame, and lower event severity attributions, while prior sexual victimization had the opposite correlations. We therefore conclude that blame and severity attributions are affected by the victim\'s behavior prior to the rape and during the rape.

    背景:基于青蒿素的联合疗法(ACT)治疗恶性疟原虫的有效性,对全球疟疾控制工作至关重要,特别是在撒哈拉以南非洲。对来自流行地区的输入病例的检查对全球范围的疟疾化疗具有影响。
    方法:一名45岁男性高烧,干咳,腹泻和全身肌肉疼痛,在莫桑比克为期两周的旅行之后。确诊恶性疟原虫感染伴寄生虫血症,患者最初接受奎宁和强力霉素治疗,然后静脉注射青蒿琥酯.为了评估药物敏感性,进行离体半最大抑制浓度测定,并对分离的恶性疟原虫基因组进行了深度测序。
    结果:临床分离物对双氢青蒿素表现出升高的离体半最大抑制浓度值,lumefantrine,甲氟喹和哌喹。基因组分析确定了恶性疟原虫Kelch13(PF3D7_1343700)基因中的I416V突变,和Kelch13相互作用候选基因的几个突变,pfkics(PF3D7_0813000,PF3D7_1138700,PF3D7_1246300),包括泛素羧基末端水解酶1,pfubp1(PF3D7_0104300)。还存在与下一代抗疟疾药物抗性相关的药物转运蛋白和基因的突变。
    结论:这个案例突出了莫桑比克携带青蒿素耐药相关基因突变的恶性疟原虫菌株的出现,对ACT药物的离体敏感性降低。必须持续监测与耐药性相关的突变,并定期监测药物敏感性,以预测莫桑比克出现的潜在耐药菌株的传播,并维持有效的疟疾控制策略。
    The effectiveness of artemisinin-based combination therapies (ACT) in treating Plasmodium falciparum, is vital for global malaria control efforts, particularly in sub-Saharan Africa. The examination of imported cases from endemic areas holds implications for malaria chemotherapy on a global scale.
    A 45-year-old male presented with high fever, dry cough, diarrhoea and generalized muscle pain, following a two-week trip to Mozambique. P. falciparum infection with hiperparasitemia was confirmed and the patient was treated initially with quinine and doxycycline, then intravenous artesunate. To assess drug susceptibility, ex vivo half-maximal inhibitory concentration assays were conducted, and the isolated P. falciparum genome was deep sequenced.
    The clinical isolate exhibited elevated ex vivo half-maximal inhibitory concentration values to dihydroartemisinin, lumefantrine, mefloquine and piperaquine. Genomic analysis identified a I416V mutation in the P. falciparum Kelch13 (PF3D7_1343700) gene, and several mutations at the Kelch13 interaction candidate genes, pfkics (PF3D7_0813000, PF3D7_1138700, PF3D7_1246300), including the ubiquitin carboxyl-terminal hydrolase 1, pfubp1 (PF3D7_0104300). Mutations at the drug transporters and genes linked to next-generation antimalarial drug resistance were also present.
    This case highlights the emergence of P. falciparum strains carrying mutations in artemisinin resistance-associated genes in Mozambique, couple with a reduction in ex vivo susceptibility to ACT drugs. Continuous surveillance of mutations linked to drug resistance and regular monitoring of drug susceptibility are imperative to anticipate the spread of potential resistant strains emerging in Mozambique and to maintain effective malaria control strategies.

    瘢痕疙瘩是一种具有挑战性的病理状况,其特征在于超出原始伤口的边界的异常瘢痕形成。尽管有可用的治疗选择,瘢痕疙瘩疤痕仍然难以管理。此病例报告讨论了一个10岁男孩,他的脖子上有瘢痕疙瘩疤痕,在分支异常修复手术后。病人接受了多种治疗,包括注射曲安奈德,冷冻疗法,和脉冲染料激光会议,有限的改进。随后,进行X线和超声检查,发现手术部位存在金属夹.据我们所知,瘢痕疙瘩瘢痕中异物的存在对其治疗反应的影响尚不清楚。这种情况的发现鼓励对手术后的瘢痕疙瘩疤痕进行影像学研究,以排除任何异物的存在。然而,在将其设定为强制性调查之前,需要更多的试验来研究异物的存在对瘢痕疙瘩治疗的影响。
    Keloid is a challenging pathological condition characterized by abnormal scarring that extends beyond the boundaries of the original wound. Despite the available treatment options, keloid scars remain difficult to manage. This case report discusses a 10-year-old boy with a keloid scar on his neck following branchial anomaly repair surgery. The patient underwent multiple treatments, including triamcinolone injections, cryotherapy, and a pulsed dye laser session, with limited improvement. Subsequently, an X-ray and ultrasound were performed revealing the presence of metallic clips over the surgical site. To our knowledge, the effect of the presence of foreign bodies within the keloid scar on its response to treatment is not well understood yet. The findings of this case encourage performing imaging studies on post-surgical keloid scars resistant to treatment to rule out the presence of any foreign material. However, more trials to investigate the effect of the presence of foreign bodies on the treatment of keloid scar are required before it can be set as a mandatory investigation.
