    背景:噬血细胞淋巴组织细胞增多症的特点是噬血细胞增多导致炎症失控;继发性噬血细胞淋巴组织细胞增多症最常见的病因是病毒感染,尤其是EB病毒.内脏利什曼病是一种由利什曼原虫引起的载体传播的原生动物疾病。在热带和亚热带地区很常见,每年有50,000-90,000个新病例。
    方法:我院收治一名15个月大的阿拉伯女性,因发热15天,体重下降。在临床检查中,她的肝脏和脾脏明显肿大,可触及肋缘以下4厘米和6厘米,分别。外周血涂片显示低色素性小红细胞性贫血,polikilocytosis,反应性淋巴细胞增多,和轻度血小板减少症.骨髓抽吸术未显示恶性肿瘤或任何其他病理发现。患者接受抗生素治疗,无改善。反复的骨髓抽吸显示红细胞吞噬作用;细胞内小的圆形生物看起来像利什曼原虫(多诺万尸体)的amastigote形式,没有恶性肿瘤的证据。她的实验室值显示铁蛋白大于500微克/升,全血细胞减少症,和高甘油三酯血症。该患者被诊断为内脏利什曼病继发的噬血细胞性淋巴组织细胞增生症。
    结论:继发于内脏利什曼病的噬血细胞性淋巴组织细胞增多症是医学文献中广泛罕见的现象,在诊断和治疗方面存在挑战。应明智地使用类固醇,以避免感染或恶性肿瘤的症状,在利什曼原虫无反应的情况下,应牢记两性霉素B的耐药性。
    BACKGROUND: Hemophagocytic lymphohistiocytosis characterized by hemophagocytosis leading to uncontrolled inflammation; the most common etiology in secondary cases of hemophagocytic lymphohistiocytosis is viral infections, especially Epstein-Barr virus. Visceral leishmaniasis is a vectorborne protozoal disease caused by Leishmania donovani complex. It is common in tropical and subtropical regions, with 50,000-90,000 new cases annually.
    METHODS: A 15-month-old Arab female was admitted to our hospital with 15 days of fever and decreased weight. On clinical examination, she had a markedly enlarged liver and spleen that were palpable 4 cm and 6 cm below the costal margin, respectively. The peripheral blood smear showed hypochromic microcytic anemia, poikilocytosis, reactive lymphocytosis, and mild thrombocytopenia. Bone marrow aspiration did not show malignancy or any other pathological findings. The patient was put on antibiotic therapy without improvement. Repeated bone marrow aspiration showed erythrophagocytosis; intracellular small round organisms looked like the amastigote form of Leishmania (Donovan bodies) with no evidence of malignancies. Her lab values showed ferritin greater than 500 ug/L, pancytopenia, and hypertriglyceridemia. The patient was diagnosed with hemophagocytic lymphohistiocytosis secondary to visceral leishmaniasis.
    CONCLUSIONS: Hemophagocytic lymphohistiocytosis secondary to visceral leishmaniasis is an extensively rare phenomenon in the medical literature that causes challenges in diagnosis and management. Steroids should be used wisely to not cover the symptoms of infections or malignancy, and amphotericin B resistance should be kept in mind in unresponsive Leishmania cases.

    背景:肺曲霉病和毛霉菌病合并感染的报道很少;因此,关于早期诊断和治疗的指导有限。我们介绍了一例混合的肺曲霉和毛霉感染,并回顾了有关这种共同感染的文献。总结该病的诊断和治疗方法,以提高临床医师对该病的认识,促进早期诊断和治疗。
    方法:一名60岁的男性农民,糖尿病控制不佳,因不明原因发烧15天,肺曲霉病并发粘液菌感染入院。
    背景:因为涉及多个叶,尽管进行了手术切除和抗真菌治疗,感染仍恶化。最后,我们用支气管镜输注两性霉素B治疗该患者。我们观察到肺部浸润的快速临床改善和随后的消退.
    结论:我们的案例强调了支气管镜在肺部侵袭性真菌病的成功临床治疗中的应用。
    BACKGROUND: Reports of pulmonary aspergillosis and mucormycosis co-infections are rare; thus, limited guidance is available on early diagnosis and treatment. We present a case of mixed pulmonary Aspergillus and Mucor infection and review the literature regarding this co-infection. The diagnosis and treatment methods are summarized to improve clinicians\' understanding of the disease and to facilitate early diagnosis and treatment.
    METHODS: A 60-year-old male farmer with poorly controlled diabetes mellitus was admitted to hospital with a fever of unknown origin that had been present for 15 days and pulmonary aspergillosis complicated by Mucor spp.
    BACKGROUND: Because multiple lobes were involved, the infection worsened despite surgical resection and antifungal therapy. Finally, we treated this patient with a bronchoscopic infusion of amphotericin B. After four courses of bronchoscopic amphotericin B infusion, we observed rapid clinical improvement and subsequent resolution of pulmonary infiltrates.
    CONCLUSIONS: Our case highlights the use of bronchoscopy in the successful clinical treatment of invasive fungal diseases of the lung.

    毛霉菌病是由毛霉菌引起的罕见机会性感染。皮肤毛霉菌病通常表现为慢性惰性感染,而犀眶毛霉菌病是一种快速进展的疾病,通常会侵袭邻近的脑组织,并伴有高死亡率。该病例代表鼻-眶-皮肤毛霉菌病的非典型临床病史。患者患有右眶蜂窝织炎,伴有广泛的多发性化脓性深部皮肤感染和头痛恶化。入院前9个月,皮肤病变是由右眶周区域的局部脓肿引起的。经过数周的无反应抗生素治疗后,真菌感染的怀疑增加。进行了右眼免洗和手术清创术的积极治疗。来自健康眼眶周围组织的周期性酸希夫染色显示带状菌丝,带有少盐和90°分支,被鉴定为Mucoraceaefamily。使用两性霉素B进行抗真菌治疗四周后,可以看到解决方案。
    Mucormycosis is a rare opportunistic infection caused by Mucorales fungi. Cutaneous mucormycosis typically present as chronic indolent infection, whereas rhino-orbital mucormycosis is rapidly progressive disease often invade the adjacent cerebral tissue associated with high mortality. This case represents the atypical clinical history of rhino-orbital-cutaneous mucormycosis. The patient was presented with a right orbital cellulitis associated with an extensive multiple suppurative deep cutaneous infection and worsening headache. The skin lesion was initiated from a localized abscess at the right periorbital area nine months before admission. Suspicion of fungal infection was raised after weeks of non-responsive antibiotics treatment. Aggressive treatment with exoneration of the right eye and surgical debridement was undertaken. Periodic acid Schiff staining from healthy periorbital tissue revealed ribbon-like hyphae with pauciseptate and 90° branching identified as Mucoraceaefamily. The resolution was seen after four weeks of antifungal treatment with Amphotericin B.

    毛霉菌病是一种侵袭性真菌感染,可导致严重的肺部感染,肺毛霉菌病(PM)是最常见的表现之一。及时诊断对患者生存至关重要,因为PM通常表现出快速的临床进展和高病死率。支气管肺泡灌洗液或支气管内活检(EBB)通常用于诊断PM,尽管文献中很少提及支气管内超声引导下经支气管针吸活检术(EBUS-TBNA)。在这份报告中,我们介绍了一例糖尿病患者的PM。虽然EBB没有产生根霉感染的证据,通过EBUS-TBNA获得明确诊断.患者接受了联合治疗,包括口服药物,雾化,和EBUS引导的两性霉素B内注射,在两性霉素B注射硫酸胆固醇复合物的初始治疗失败后,显着改善。我们的病例强调了EBUS-TBNA不仅可以用于纵隔淋巴结病,而且可以用于获得腔外病变标本。此外,对于对单一疗法反应不足且无法获得手术治疗的患者,在全身静脉治疗中加入EBUS引导下的病灶内注射两性霉素B可能产生意想不到的效果.
    Mucormycosis is an invasive fungal infection that can result in severe lung infections, with pulmonary mucormycosis (PM) being one of the most prevalent manifestations. Prompt diagnosis is crucial for patient survival, as PM often exhibits rapid clinical progression and carries a high fatality rate. Broncho-alveolar lavage fluid or endobronchial biopsy (EBB) has been commonly employed for diagnosing PM, although there is limited mention of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the literature. In this report, we present a case of PM in a patient with diabetes. While EBB did not yield evidence of Rhizopus infection, a definitive diagnosis was obtained through EBUS-TBNA. The patient underwent combination therapy, including oral medication, nebulization, and EBUS-guided intrafocal amphotericin B injection, which resulted in significant improvement following the failure of initial therapy with amphotericin B injection cholesterol sulfate complex. Our case highlights the potential of EBUS-TBNA not only for mediastinal lymphadenopathy but also for obtaining extraluminal lesion specimens. Furthermore, for patients with an inadequate response to mono-therapy and no access to surgical therapy, the addition of EBUS-guided intralesional amphotericin B injection to systemic intravenous therapy may yield unexpected effects.

    Mucormycosis is a rare fungal infection caused by fungi of the Mucorales order that occurs in immunocompromised individuals or with loss of skin or mucosa barrier integrity. This report presents four cases of rhinocerebral mucormycosis attended at a third-level hospital in Cali (Colombia) during a period of three years. All patients had different case histories and times of evolution. All four had a previous or de novo diagnosis of type 2 diabetes mellitus, with glycated hemoglobin higher than 10% on admission. We ruled out other possible pathologies that could explain their immunocompromised condition. Mucormycosis diagnosis was made with direct visualization of hyaline coenocytic hyphae on biopsies. The basis of treatment was liposomal amphotericin B and surgical debridement. Two patients presented bacterial coinfection. One asked for voluntary discharge without having completed the treatment, and another one died. The remaining two have attended controls and had an adequate evolution.
    La mucormicosis es una infección fúngica poco frecuente causada por hongos del orden Mucorales, la cual se presenta en individuos inmunocomprometidos o con pérdida de la integridad de la barrera de piel o mucosas. Se reportan cuatro casos de mucormicosis rinocerebral atendidos en un hospital de tercer nivel de Cali (Colombia) durante un periodo de tres años. Los cuatro pacientes presentaron diferentes cuadros clínicos y tiempos de evolución. Todos tenían diagnóstico de diabetes mellitus de tipo 2, de novo o previo, con una hemoglobina glucosilada de ingreso mayor del 10 % y en todos se descartaron otras enfermedades que explicaran su compromiso inmunitario. La mucormicosis se diagnosticó por la visualización directa de hifas hialinas sincitiales (coenocytic) en las biopsias tomadas. El pilar del tratamiento fue la anfotericina B liposómica junto con el desbridamiento quirúrgico. Dos pacientes presentaron coinfección bacteriana. De los cuatro, uno firmó su egreso voluntario sin completar el tratamiento y otro falleció. Los dos pacientes restantes han asistido a los controles y han mostrado una adecuada evolución.

    我们报告了一例72岁的女性发烧,腹痛,伴有白细胞减少症的腹泻,贫血,和血小板减少症.通过骨髓穿刺证实了急性再生障碍性贫血的诊断。治疗包括糖皮质激素,免疫球蛋白治疗,和血浆置换。随后,患者出现消化道出血,腹部计算机断层扫描(CT)显示横结肠穿孔。手术切除病变组织的病理检查证实粘液感染。尽管接受了两性霉素B的抗真菌治疗,由于败血症进展,患者的病情恶化。免疫功能低下患者的粘液感染应保持警惕,早期诊断可能有助于改善预后。
    We report a case of a 72-year-old female who presented with fever, abdominal pain, and diarrhea accompanied by leukopenia, anemia, and thrombocytopenia. The diagnosis of acute aplastic anemia was confirmed through bone marrow aspiration. Treatment included glucocorticoids, immunoglobulin therapy, and plasma exchange. Subsequently, the patient developed gastrointestinal bleeding and abdominal Computed Tomography (CT) revealed perforation of the transverse colon. Pathological examination of surgically removed diseased tissue confirmed mucor infection. Despite receiving antifungal therapy with amphotericin B, the patient\'s condition deteriorated due to the sepsis progression. Mucor infection in immunocompromised patients should be vigilant, and early diagnosis may help improve prognosis.

    皮肤利什曼病在伊朗流行。
    我们试图研究皮肤利什曼病患者的治疗结果和治疗并发症。
    本病例系列纳入了2018年至2019年在伊朗访问我们中心的经涂片证实的皮肤利什曼病患者。
    总共,36例患者接受了皮损内的葡甲胺治疗,肌内锑酸葡甲胺,葡萄糖酸钠,和两性霉素B。这种治疗对81.8%的患者有效。6.1%和12.1%的患者出现复发和治疗失败,分别。病灶内治疗,肌内锑酸葡甲胺,葡萄糖酸钠,两性霉素B的清除率为80.8%,92.3%,75%,85.7%,分别。清除与病灶内注射锑酸葡甲胺之间较短的时间间隔相关(p=0.006),复发与注射之间较长的时间间隔相关(p=0.018)。每个患者的平均副作用数量,葡萄糖酸钠,肌内锑酸葡甲胺,两性霉素B分别为0.62,1.4,1.6和2.8.最常见的副作用,肌内锑酸葡甲胺,两性霉素B是局部疼痛,关节痛,和低钾血症,分别。
    低样本量是本研究的局限性。
    肌内注射锑酸葡甲胺的治愈率高于两性霉素B,高于葡萄糖酸钠的治愈率。在病灶内治疗的患者中,缩短注射间隔时间增加了清除率,降低了复发率.
    UNASSIGNED: Cutaneous leishmaniasis is endemic in Iran.
    UNASSIGNED: We sought to investigate the therapeutic outcomes and complications of treatment in patients with cutaneous leishmaniasis.
    UNASSIGNED: This case series enrolled patients with smear-proven cutaneous leishmaniasis who visited our center in Iran from 2018 to 2019.
    UNASSIGNED: In total, 36 patients were treated with intralesional meglumine antimoniate, intramuscular meglumine antimoniate, sodium stibogluconate, and amphotericin B. Overall, this treatment was effective in 81.8 percent of patients. Relapse and treatment failure occurred in 6.1 percent and 12.1 percent of patients, respectively. Treatment with intralesional meglumine antimoniate, intramuscular meglumine antimoniate, sodium stibogluconate, and amphotericin B yielded a clearance rate of 80.8 percent, 92.3 percent, 75 percent, and 85.7 percent, respectively. Clearance was associated with a shorter time interval between injections of intralesional meglumine antimoniate (p=0.006) and relapse was associated with a longer time interval between injections (p=0.018). The average number of side effects per patient for intralesional meglumine antimoniate, sodium stibogluconate, intramuscular meglumine antimoniate, and amphotericin B was 0.62, 1.4, 1.6, and 2.8, respectively. The most common side effect of intralesional meglumine antimoniate, intramuscular meglumine antimoniate, and amphotericin B was local pain, arthralgia, and hypokalemia, respectively.
    UNASSIGNED: Low sample size was the limitation of this study.
    UNASSIGNED: The cure rate of intramuscular meglumine antimoniate was higher than amphotericin B, which was higher than the cure rate of sodium stibogluconate. In patients treated with intralesional meglumine antimoniate, reducing the time interval between injections increased the clearance rate and decreased the rate of relapse.

    皮肤科假单胞菌瘤(DPM),这是皮肤癣菌的更深的皮肤和/或皮下感染,在韩国国内的短毛猫中很少有报道。一个三岁的孩子,Spyed女性,国内韩国短毛猫提出了一个历史的硬皮,结节,瘙痒1年。在最初的演讲中,在她的腹侧胸腔上发现了覆盖着淡黄色颗粒的多灶性溃疡性结节,腹部,侧翼,和左后肢。溃疡性结节的细胞学显示中性粒细胞变性,巨噬细胞,多核巨细胞,和菌丝。结节的组织学检查显示脓性肉芽肿性皮炎伴真菌斑块,在培养物中鉴定出犬小孢子菌和金黄色葡萄球菌。因此,这只猫被诊断为患有继发性脓皮病的DPM。口服伊曲康唑(10mg/kg,一天一次)被施用,但没有观察到显著的改善。因此,损伤内(IL)注射两性霉素B(0.6mg/结节)和口服特比萘芬(30mg/kg,一天两次)给猫服用。有了这些药物,溃疡和结节的数量和大小显着减少,虽然大的圆顶状结节仍然存在。皮肤病变采用口服特比萘芬和伊曲康唑治疗5个月。然而,6个月后,观察到多灶性溃疡性结节复发,猫在初次陈述后10个月死亡。在这种情况下,IL两性霉素B和口服特比萘芬在DPM治疗中部分有效,这表明这可能是DPM治疗的一种选择。有必要进一步研究以确定IL两性霉素B在DPM管理中的剂量和频率。
    Dermatophytic pseudomycetoma (DPM), which is a deeper dermal and/or subcutaneous infection of dermatophytes, has been rarely reported in Domestic Korean Short Hair Cats. A 3-year-old, spayed female, domestic Korean Short Hair Cat presented with a history of crusts, nodules, and pruritus for 1 year. At the initial presentation, multifocal ulcerative nodules covered with yellowish grains were noted on her ventral thorax, abdomen, flank, and left hindlimb. Cytology of ulcerative nodules revealed degenerative neutrophils, macrophages, multinucleated giant cells, and hyphae. Histological examination of nodules revealed pyogranulomatous dermatitis with fungal plaques, and Microsporum canis and Staphylococcus aureus were identified in the culture. Therefore, the cat was diagnosed with DPM with secondary pyoderma. Oral itraconazole (10 mg/kg, once a day) was administered, but no significant improvement was observed. Therefore, intralesional (IL) injection of amphotericin B (0.6 mg/nodule) and oral administration of terbinafine (30 mg/kg, twice a day) were administered to the cat. With these medications, ulceration and the number and size of nodules decreased significantly, although large dome-shaped nodules remained. Skin lesions were treated with oral terbinafine and itraconazole administration for 5 months. However, after 6 months, recurrence of multifocal ulcerative nodules was observed, and the cat died 10 months after initial presentation. In this case, IL amphotericin B and oral terbinafine administration were partially effective in DPM treatment, suggesting that this may be an option for DPM treatment. Further studies to determine dose and frequency of IL amphotericin B in the management of DPM are warranted.
