    阴沟肠杆菌是肠杆菌属发病和死亡的主要原因。它主要导致医院感染,尤其是在儿童中,老年人和患有潜在疾病的人。然而,据报道,由阴沟肠杆菌引起的社区获得性菌血症病例。阴沟肠杆菌引起多药耐药感染的倾向日益增加,这使得治疗特别具有挑战性。一名25个月大的男童被送往冈比亚一家乡村医院,有一周的持续高烧史,呼吸困难,和厌食症。演讲前两天,他开始出现全身性强直-阵挛性癫痫发作。在检查中,他被发现发烧,呼吸困难,苍白,和心动过速.他修改后的格拉斯哥昏迷量表得分为9/15。调查显示C反应蛋白升高,低血红蛋白,白细胞计数升高.脑脊液培养没有产生任何生长。从入院当天采集的血培养物中分离阴沟肠杆菌。病原体对所有可用的抗生素具有抗性。他接受了全血输注,最初用阿莫西林-克拉维酸和庆大霉素进行了经验性治疗。前者改为头孢呋辛,因为孩子没有好转。孩子入院后九天死亡。尽管阴沟肠杆菌主要以引起医院感染而闻名,致命的社区获得性感染也会发生。该病例报告表明,在低资源环境中治疗耐多药阴沟肠杆菌的困难及其导致致命感染的倾向。
    Enterobacter cloacae is the leading cause of morbidity and mortality in the genus Enterobacter. It mostly causes nosocomial infections, especially in children, the elderly and those with underlying diseases. However, cases of community-acquired bacteraemia caused by E. cloacae have been reported. The increasing inclination of E. cloacae to cause multidrug-resistant infections has made it particularly challenging to treat. A 25-month-old male child presented to a rural hospital in The Gambia with a one-week history of persistent high-grade fever, dyspnoea, and anorexia. Two days before presentation, he began to have generalized tonic-clonic seizures. On examination, he was found to be febrile, dyspnoeic, pale, and tachycardic. He had a modified Glasgow Coma Scale score of 9/15. Investigations revealed an elevated C-reactive protein, low haemoglobin, and elevated white blood cell count. Cerebrospinal fluid culture did not yield any growth. E. cloacae was isolated from a blood culture taken on the day of admission. The pathogen was resistant to all available antibiotics. He was transfused with whole blood and initially treated empirically with amoxicillin-clavulanic acid and gentamicin. The former was changed to cefuroxime because the child had not improved. The child died nine days after admission. Although E. cloacae is primarily known for causing nosocomial infections, fatal community-acquired infections also occur. This case report demonstrates the difficulty in treating multidrug-resistant E. cloacae in a low-resource setting and its propensity to cause fatal infections.

    背景:寻找耐药结核病(DR-TB)患者对于控制大流行和改善患者临床预后非常重要。据我们所知,评估有效性的系统评价,成本效益,可接受性,以及不同的DR-TB病例发现策略为研究提供信息的可行性,政策,和实践,尚未进行,初步研究的范围未知。
    目的:因此,我们评估了有关DR-TB病例发现策略的现有文献。
    方法:我们研究了系统评价,试验,定性研究,诊断测试准确性研究,以及其他旨在改善DR-TB病例检测的主要研究。我们排除了包括寻求结核病(TB)症状的患者的研究,已经诊断为结核病的患者,或者是基于实验室的。我们搜索了MEDLINE的学术数据库,Embase,科克伦图书馆,非洲信息,CINAHL(护理和相关健康文献累积指数),认识论,和PROSPERO(国际前瞻性系统审查登记册),没有语言或日期限制。我们筛选了标题,摘要,和全文一式两份。在Excel(微软公司)中进行数据提取和分析。
    结果:我们筛选了3646篇标题和摘要以及236篇全文文章。我们确定了6项系统评价和61项主要研究。五篇评论描述了接触调查的成果,并侧重于家庭接触,航空公司联系人,药物敏感结核病和DR-TB接触之间的比较,以及索引病例和接触者之间DR-TB谱的一致性。一篇综述比较了通用和选择性耐药性测试。主要研究描述了(1)34项接触调查,(2)17次疫情调查,(3)3航空公司联系调查,(4)5项流行病学分析,(5)1个公私合作计划,和(6)电子注册程序。主要研究均为描述性研究,包括项目数据的横断面和回顾性综述。没有确定试验。由于相关信息的报告不完整,很难从接触调查中提取数据。
    结论:可以更新现有的描述性评论,但是对有效性缺乏了解,成本效益,可接受性,以及为政策和实践提供信息的DR-TB病例发现策略的可行性。还需要术语的标准化,设计,和报告DR-TB病例发现研究。
    BACKGROUND: Finding individuals with drug-resistant tuberculosis (DR-TB) is important to control the pandemic and improve patient clinical outcomes. To our knowledge, systematic reviews assessing the effectiveness, cost-effectiveness, acceptability, and feasibility of different DR-TB case-finding strategies to inform research, policy, and practice, have not been conducted and the scope of primary research is unknown.
    OBJECTIVE: We therefore assessed the available literature on DR-TB case-finding strategies.
    METHODS: We looked at systematic reviews, trials, qualitative studies, diagnostic test accuracy studies, and other primary research that sought to improve DR-TB case detection specifically. We excluded studies that included patients seeking care for tuberculosis (TB) symptoms, patients already diagnosed with TB, or were laboratory-based. We searched the academic databases of MEDLINE, Embase, The Cochrane Library, Africa-Wide Information, CINAHL (Cumulated Index to Nursing and Allied Health Literature), Epistemonikos, and PROSPERO (The International Prospective Register of Systematic Reviews) using no language or date restrictions. We screened titles, abstracts, and full-text articles in duplicate. Data extraction and analyses were carried out in Excel (Microsoft Corp).
    RESULTS: We screened 3646 titles and abstracts and 236 full-text articles. We identified 6 systematic reviews and 61 primary studies. Five reviews described the yield of contact investigation and focused on household contacts, airline contacts, comparison between drug-susceptible tuberculosis and DR-TB contacts, and concordance of DR-TB profiles between index cases and contacts. One review compared universal versus selective drug resistance testing. Primary studies described (1) 34 contact investigations, (2) 17 outbreak investigations, (3) 3 airline contact investigations, (4) 5 epidemiological analyses, (5) 1 public-private partnership program, and (6) an e-registry program. Primary studies were all descriptive and included cross-sectional and retrospective reviews of program data. No trials were identified. Data extraction from contact investigations was difficult due to incomplete reporting of relevant information.
    CONCLUSIONS: Existing descriptive reviews can be updated, but there is a dearth of knowledge on the effectiveness, cost-effectiveness, acceptability, and feasibility of DR-TB case-finding strategies to inform policy and practice. There is also a need for standardization of terminology, design, and reporting of DR-TB case-finding studies.

    背景:胃肠道间质瘤(GIST)在年轻人中很少见,通常在出现症状或处于晚期后才发现。在这里,我们报告了1例完全复位手术的病例,该病例是在一名年轻女性患者中成功完成R0手术,该患者患有大量恶性胃GIST伴多发性肝转移.
    方法:一名18岁妇女因厌食症和呕吐来我院就诊,并诊断为17cm胃GIST伴横结肠浸润和多发肝转移。由于被认为是不可切除的,酪氨酸和多激酶抑制剂疗法被施用至第四行,没有反应。经过在多学科小组会议上的认真讨论,胰十二指肠切除术或远端胃切除术,横结肠切除术,并计划切除肝转移瘤。因此,远端胃切除术,横结肠切除术,切除肝转移瘤,并进行了偶然的腹膜转移。尽管手术的主要目标是尽可能减小肿瘤的体积,结果显示,所有可检测的肿瘤均已完全切除.长期伊马替尼辅助治疗术后27个月未观察到复发。
    结论:即使对于高度先进的GIST,积极手术后辅助药物治疗可能会延长年轻患者的生存期.
    BACKGROUND: Gastrointestinal stromal tumors (GISTs) are rare in young people and are often detected after becoming symptomatic or at an advanced stage. Herein, we report a case of complete reduction surgery for a substantially large malignant gastric GIST with multiple liver metastases in a young woman who successfully resulted in R0 surgery.
    METHODS: An 18-year-old woman presented to our hospital with anorexia and vomiting, and was diagnosed with a 17 cm gastric GIST with transverse colon invasion and multiple liver metastases. Due to being considered unresectable, tyrosine and multi-kinase inhibitor therapy were administered up to the fourth line yielding no response. After careful discussion at a multidisciplinary team conference, pancreatoduodenectomy or distal gastrectomy, transverse colectomy, and resection of the liver metastases were planned. Consequently, distal gastrectomy, transverse colectomy, resection of the liver metastases, and incidental peritoneal metastases were performed. Although the primary goal of the surgery was to reduce the volume of the tumor as much as possible, the results revealed that the complete removal of all detectable tumors was achieved. No recurrence was observed after surgery for 27 months with long-term adjuvant imatinib therapy.
    CONCLUSIONS: Even for highly advanced GISTs, aggressive surgery followed by adjuvant drug therapy may prolong survival in young patients.

    结核病(TB)是全球发展中地区最主要的传染病之一。正如世界卫生组织(世卫组织)所指出的那样,耐药结核病(DR-TB)的病例数最近有所增加.该病例报告描述了原发性肺外多药耐药结核性胸腔积液的有效诊断和定制治疗。一种由于细菌计数相对较低以及抗酸杆菌(AFB)的ZiehlNeelsen(ZN)染色通常为阴性而难以鉴定的疾病。导致耐多药结核病(MDR-TB)的细菌对至少两种药物具有抗药性,异烟肼和利福平,最有效的结核病药物。我们将介绍一个60岁的男性抱怨呼吸困难的案例,咳嗽,体重减轻一个月,胸痛和发烧12天。对患者进行了胸腔积液检查,显示渗出液(根据Light's标准),腺苷脱氨酶(ADA)阳性。进行了基于药筒的核酸扩增测试(CBNAAT)和线探针测定(LPAs),提示结核分枝杆菌(MTB)对利福平和异烟肼耐药。患者根据WHO标准开始口服bedaquiline,导致显著改善。这一病例揭示了为了及时诊断和治疗DR-TB,胸腔积液,和胸膜活检需要早期暴露于调查,如Xpert(MTB)/对利福平测定的抗性,培养,和基因型药物敏感性测试(DST)。
    Tuberculosis (TB) is among the most predominant infectious illnesses in developing areas around the globe. As stated by the World Health Organization (WHO), the number of instances of drug-resistant tuberculosis (DR-TB) has increased lately. This case report describes the effective diagnosis and customized treatment for primary extra-pulmonary multidrug-resistant tubercular pleural effusion, a disease which is difficult to identify due to relatively low bacterial count as well as frequently negative staining on Ziehl Neelsen (ZN) for acid-fast bacilli (AFB). The bacteria causing multidrug-resistant tuberculosis (MDR-TB) is resistant to a minimum of two drugs, isoniazid and rifampicin, the most effective TB medications. We are going to present the case of a 60-year-old male who complained of breathlessness, cough, and loss of weight for one month and chest pain and fever for 12 days. The patient\'s pleural fluid examination was carried out, which showed exudative fluid (according to Light\'s criteria) with adenosine deaminase (ADA) positive. Cartridge-based nucleic acid amplification test (CBNAAT) and line probe assays (LPAs) were carried out, which suggested mycobacterium tuberculosis (MTB) with rifampicin and isoniazid resistance. The patient was started an oral regimen with bedaquiline in accordance with WHO standards, leading to significant improvement. This case reveals that to promptly diagnose and treat DR-TB, pleural effusions, and pleural biopsies need to be exposed early to investigations such as Xpert (MTB)/resistance to rifampicin assay, culturing, and genotype drug sensitivity testing (DST).

    背景:嗜麦芽窄食单胞菌是已知在人类中引起机会性和医院感染的革兰氏阴性菌。嗜麦芽窄食链球菌是一种新兴的病原体,由于它的患病率越来越高,不同的疾病谱,免疫功能低下个体的内在多药耐药性和高死亡率。嗜麦芽窄食链球菌是与显著的发病率和死亡率相关的新生儿败血症的罕见原因。这种细菌的多药耐药性对治疗提出了相当大的挑战,各种机制有助于其抵抗。
    方法:我们报告一例40岁的非洲男性新生儿出现新生儿败血症症状。血培养显示嗜麦芽窄食单胞菌,对环丙沙星和庆大霉素敏感,但对其他抗生素耐药。由于父亲拒绝了,无法进行CSF的腰椎穿刺。我们根据国家指南静脉注射氨苄西林和庆大霉素对新生儿进行了6天的经验性一线抗生素治疗,孩子完全康复,血液培养反复阴性。
    结论:本报告描述了一例由嗜麦芽嗜血杆菌引起的新生儿败血症病例,一种多重耐药细菌和新生儿败血症的罕见原因。我们报告说,基于局部抗菌谱数据的细菌和抗菌管理的早期检测对于成功的患者管理可能是至关重要的。
    BACKGROUND: Stenotrophomonas maltophilia is a gram-negative bacteria known for causing opportunistic and nosocomial infections in humans. S. maltophilia is an emerging pathogen of concern due to it\'s increasing prevalence, diverse disease spectrum, intrinsic multi-drug resistance and high mortality rates in immunocompromised individuals. S. maltophilia is a rare cause of neonatal sepsis associated with significant morbidity and mortality. The bacterium\'s multi-drug resistance poses a considerable challenge for treatment, with various mechanisms contributing to its resistance.
    METHODS: We report a case involving a 40-h-old male African neonate who exhibited symptoms of neonatal sepsis. The blood culture revealed Stenotrophomonas maltophilia, which was sensitive to ciprofloxacin and gentamicin but resistant to other antibiotics. Lumbar puncture for CSF could not be done because the father declined. We treated the newborn with the empirical first-line antibiotics as per the national guideline intravenous ampicillin and gentamicin for six days, and the child recovered fully with a repeated negative blood culture.
    CONCLUSIONS: This report describes a neonatal sepsis case caused by S. maltophilia, a multi-drug resistant bacteria and a rare cause of neonatal sepsis. We report that early detection of the bacterial and antimicrobial management based on local antibiogram data may be essential for successful patient\'s management.

    背景:骨关节结核是这种疾病的罕见表现,通常构成诊断挑战,需要额外的诊断成像方式,如射线照相术,CT,MRI。本文介绍了一系列5例,涉及影响足和脚踝骨骼的结核病,在不同阶段诊断。患者按照国家方案接受了适当的抗结核药物治疗,必要时进行手术干预。
    方法:在本系列中,我们描述了5例足踝骨结核的临床特征和治疗。这些病例在不同阶段被诊断出来,所有患者均根据国家治疗指南接受标准抗结核药物治疗。在认为必要时进行手术干预以优化患者预后。
    结论:在任何具有不确定特征的临床情况下,都应考虑诊断为骨结核。持续的症状,或对常规治疗方法的抵抗力。至关重要的是采用涉及医学和外科管理的多学科方法来有效解决这种具有挑战性的疾病。然而,重要的是要注意,手术干预不能取代适当药物治疗的必要性。
    结论:累及足踝骨的结核病很少发生。然而,考虑到当地的情况,及时的治疗干预对于防止严重的骨关节损伤至关重要。早期诊断,坚持既定的治疗方案,包括医疗和手术方式的综合方法对于成功管理这种罕见的实体至关重要。
    BACKGROUND: Osteo-articular tuberculosis is a rare manifestation of this disease, often posing diagnostic challenges that necessitate additional diagnostic imaging modalities such as radiography, CT, and MRI. This article presents a series of five cases involving tuberculosis affecting the bones of the foot and ankle, diagnosed at various stages. The patients received appropriate anti-tuberculosis medical treatment following national protocols, along with surgical interventions when necessary.
    METHODS: In this series, we describe the clinical characteristics and management of five cases of foot and ankle bone tuberculosis. These cases were diagnosed at different stages, and all patients received standard anti-tuberculosis medical therapy according to national treatment guidelines. Surgical interventions were performed when deemed necessary to optimize patient outcomes.
    CONCLUSIONS: The diagnosis of bone tuberculosis should be considered in any clinical scenario that presents with uncertain features, persistent symptoms, or resistance to conventional treatment approaches. It is crucial to employ a multidisciplinary approach involving medical and surgical management to effectively address this challenging disease. However, it is important to note that surgical intervention cannot replace the necessity of proper medical treatment.
    CONCLUSIONS: Tuberculosis involving the bones of the foot and ankle remains an infrequent occurrence. However, considering the endemic context, prompt therapeutic interventions are essential to prevent significant osteoarticular damage. Early diagnosis, adherence to established treatment protocols, and a comprehensive approach encompassing both medical and surgical modalities are crucial for successful management of this rare entity.

    细菌耐药性中最紧迫的新兴问题之一是多重耐药肺炎克雷伯菌。肺炎克雷伯菌感染的治疗通常是有问题的,因为缺乏可用的治疗选择。导致对发病率的负面影响,死亡率,和医疗保健相关成本。卡里霉素是一种大环内酯类抗生素,具有良好的抗菌作用。在这项研究中,我们报道了1例诊断为多重耐药肺炎克雷伯菌感染的患者,该患者接受了卡利霉素治疗.病人出现咳嗽,咳痰,呼吸困难,和需要无创通气的严重低氧血症。我们先后使用了多种抗生素,包括美罗培南,替加环素,和多粘菌素,结果不满意。最后,我们用了卡里霉素,病人的病情好转了,导致出院。因此,对于对常规抗感染治疗无反应的多药耐药肺炎克雷伯菌感染患者,carrimamin可以被认为是一种治疗选择.
    One of the most pressing emerging issues in bacterial resistance is multidrug-resistant Klebsiella pneumoniae. The treatment of K. pneumoniae infections is often problematic because of the lack of available therapeutic options, leading to negative effects on morbidity, mortality, and healthcare-associated costs. Carrimycin is a macrolide antibiotic with good antibacterial effects. In this study, we report a patient diagnosed with multidrug-resistant K. pneumoniae infection who was treated with carrimycin. The patient presented with cough, expectoration, dyspnea, and severe hypoxemia requiring noninvasive ventilation. We successively used a variety of antibiotics, including meropenem, tigecycline, and polymyxin, with unsatisfactory results. Finally, we used carrimycin, and the patient\'s condition improved, resulting in hospital discharge. Therefore, for patients with multidrug-resistant K. pneumoniae infection that does not respond to conventional anti-infective treatments, carrimycin can be considered a treatment option.

    我们介绍了一个73岁的男性,有终末期肾病(ESRD)的历史,透析,2型糖尿病,冠状动脉疾病状态支架术后,前列腺癌放射后状态,前列腺切除术,复发性膀胱颈挛缩需要耻骨上导管,左尿道狭窄与肾造瘘管放置,阴茎植入物,和复发性尿路感染,他去急诊室抱怨双侧腹股沟持续疼痛一天。体格检查对耻骨上压痛和慢性耻骨上导管和左侧肾造瘘管具有重要意义。初步检查病人的尿液显示浑浊,黄色液体,白细胞呈阳性,白细胞酯酶,和细菌。获得尿液培养物,美洲大肠杆菌呈阳性,具有>100,000个菌落形成单位(CFU)以及粪肠球菌(E.粪肠)表现出低菌落数。该患者每天两次接受为期7天的美罗培南1克的治疗,改善了他的症状,然后完成每天500毫克的厄他培南10天疗程。患者在透析日接受了为期五天的万古霉素1gm疗程,以额外覆盖粪肠球菌,尽管殖民地数量低。这是第一例由美洲大肠杆菌引起的尿路感染病例。这种生物主要存在于免疫受损的个体中,关于它是真正的病原体还是主要作为机会性感染存在的争论仍在进行中。我们建议对这种抗性生物进行进一步的调查和研究对于确立其在免疫功能低下和免疫能力强的个体中的作用至关重要。美洲大肠杆菌是一种耐多药的生物,迄今为止,关于其患病率和潜在发病率的文献很少,尤其是在妥协的个人。在抗生素耐药性增加的时代,我们建议需要更多的研究来了解美洲大肠杆菌的致病性。
    We present a 73-year-old male with a history of end-stage renal disease (ESRD) on dialysis, type 2 diabetes mellitus, coronary artery disease status post stents, prostate carcinoma status post radiation, and prostatectomy, with recurrent bladder neck contracture requiring suprapubic catheter, left urethral stricture with nephrostomy tube placement, penile implant, and recurrent urinary tract infections, who presented to the emergency room complaining of constant bilateral groin pain for one day. Physical exam was significant for suprapubic tenderness and a chronic suprapubic catheter and left-sided nephrostomy tube. An initial examination of the patient\'s urine revealed turbid, yellow-colored fluid, positive for white blood cells, leukocyte esterase, and bacteria. A urine culture was obtained, which returned positive for E. americana,  with >100,000colony-forming units (CFUs)as well as Enterococcus faecalis (E. faecalis) demonstrating low colony counts. The patient was treated with a seven-day course of meropenem 1 gm twice daily, which improved of his symptoms, and then completed a 10-day course of ertapenem 500 mg daily. The patient received a five-day course of vancomycin 1 gm on dialysis days for additional coverage of E. faecalis, despite low colony counts. This is the first documented case of a urinary tract infection caused by E. americana. The organism is primarily found in immunocompromised individuals, and a debate is still ongoing as to whether it is a true pathogen or exists primarily as an opportunistic infection. We suggest further inquiry and study of this resistant organism are paramount in establishing its role in both immunocompromised as well as immunocompetent individuals. E. americana is a multidrug-resistant organism, which to date has sparse documentation regarding its prevalence and potential for morbidity, especially in compromised individuals. In the era of increasing antibiotic resistance, we suggest that more research is needed to understand the pathogenicity of E. americana.
