Nocardiosis has been recognized in recent times as an unusual opportunistic infection associated with HIV. Bacteraemia due to this pathogen is even rarer and only few cases have been reported in the literature. We report here a case of pulmonary nocardiosis with bacteraemia, which was initially diagnosed as pulmonary tuberculosis. A high index of suspicion is required to diagnose this infection as the clinical presentation and radiographic features mimic pulmonary tuberculosis. 相似文献

Empyema thoracis by Nocardia farcinica infection is uncommon. Here we report a rare and fatal infection in a 27-year-old HIV- seropositive male who presented with cough, expectoration, and breathlessness. Nocardia farcinica was isolated from sputum and pus from the pleural cavity. Confirmation of the isolate and minimum inhibitory concentrations (MIC) for various antibiotics was done at the Aerobic Actinomycetes Reference Laboratory, Centres for Disease Control and Prevention (CDC), Atlanta. Patient was treated with suitable antibiotics and antiretroviral drugs in spite of which he eventually succumbed to the disease. 相似文献

Nocardia asteroides was isolated after prolonged culture from the pericardial fluid of a human immunodeficiency virus-infected patient. The lengthy duration required for culture growth and identification of this N. asteroides isolate affected both initial therapeutic decisions and patient management. A proposed algorithm for the microbiological workup of pericardial fluid for possible Nocardia spp. is described in an effort to improve the timeliness of results. 相似文献

The approach to the patient with a difficult melanocytic lesion 总被引:3,自引:0,他引:3
Although most histological diagnoses are made with relative ease and with great specificity and reproducibility, there is a subset of cases in which a specific and reproducible diagnosis is difficult or even impossible to render. In the melanocytic system, these cases can be divided into two broad categories. The first category, 'superficial atypical melanocytic proliferations of uncertain significance' (SAMPUS), includes predominantly junctional melanocytic proliferations, and melanocytic proliferations that are confined to the epidermis and papillary dermis, without evidence of tumorigenic proliferation or mitotic activity there. The prognosis for cure of these lesions is excellent if they are completely excised. Such lesions may include, for example, dysplastic naevi, Spitz naevi or pigmented spindle cell naevi with a few atypical melanocytes above the dermal-epidermal junction, or with greater than average cytological atypia, or with mitoses, where the differential diagnosis of melanoma in situ is difficult or impossible to rule out. The other category, 'melanocytic tumours of uncertain malignant potential' (MELTUMP), is comprised of melanocytic proliferations that form tumours in the dermis, and are therefore potentially capable of metastasis. Examples of such lesions may include atypical Spitz naevi, deep penetrating naevi, possible naevoid melanomas, or cellular blue naevi, where because of increased mitotic activity or cytologic atypia, a diagnosis of invasive or tumorigenic melanoma cannot be ruled out. In managing such lesions, we follow two main principles. The first is to manage each lesion with therapy designed to be adequate for management of the most significant consideration in the differential diagnosis. The second principle is to make clinicians and patients specifically aware of the diagnostic difficulty in their lesion, so that management can be undertaken on a true informed consent basis. 相似文献

This is a report of an unusual case of Nocardia brasiliensis causing primary pulmonary nocardiosis with disseminated subcutaneous lesions in an immunocompetent patient. This case highlights the importance of considering nocardiosis as a differential diagnosis in patients with pulmonary and cutaneous lesions and the need for vigorous management for complete cure. 相似文献

We present an autopsy case of concomitant pulmonary aspergillosis and nocardiosis undiagnosed during life in a long-term surviving renal transplant recipient. The patient had fever and a newly developed cavitary lesion on a chest x-ray. The working diagnosis was pulmonary tuberculosis with possible colonization by Aspergillus species. Cultures of bronchial washings became positive for Aspergillus fumigatus 1 day after death. The study of tissue from the lung cavity at autopsy revealed Aspergillus fumigatus (confirmed by postmortem culture) and the filaments of Nocardia species. Increased numbers of surviving immunosuppressed patients will require aggressive, comprehensive diagnostic techniques for the detection of polymicrobial infections. 相似文献

Imatinib mesylate (STI 571, Gleevec) is a potent bcr-abl tyrosine kinase inhibitor. It also inhibits c-kit tyrosine kinase. Imatinib mesylate is active in the treatment of cronic myeloid leukemia (CML) and gastrointestinal stromal tumors (GIST). It is considered by some authorities to be the standard of care in newly diagnosed CML as well as patients in chronic phase who do not have a related match. C-kit and its ligand stem-cell factor regulate melanocyte development and survival. Hypopigmentation in patients receiving imatinib mesylate for CML has been reported recently. In this article, we report a black Nigerian male with GIST, who developed hypopigmentation of distal parts of digits, as well as generalized lightening of skin on the body three months after receiving imatinib mesylate. We believe that this is the first case of hypopigmentation reported in a black patient with GIST. 相似文献

Ocular nocardiosis is an opportunistic infection and is believed to be a rare entity. We describe a rare case report of a patient with culture-positive Nocardia asteroides canaliculitis who presented with complaints of watering, purulent discharge and painful swelling of left lower eye lid. A purulent tenacious material was expressed from the punctum of lower eye lid and subjected to microbiological investigations such as smears and cultures. Smears and culture proved the presence of Nocardia asteroides in the sample collected from punctum. 相似文献

During the period 1966-77, 24 strains of Flavobacterium odoratum were identified from among strains of Gram-negative, non-fermentative bacteria submitted to the National Collection of Type Cultures for computer-assisted identification. The F. odoratum strains showed resistance to therapeutic levels of gentamicin, tobramycin, amikacin, and carbenicillin as well as to several other antimicrobial agents generally useful in the treatment of infections caused by Gram-negative, non-fermentative bacteria. Two strains isolated from amputation stumps and another three strains isolated in significant numbers from urine specimens were possibly opportunist pathogens. The biochemical characteristics of the 24 strains, the proposed neotype strain of F. odoratum, and three strains representative of a group, referred to at the Center for Disease Control, Atlanta as group M-4f, were compared with those of biochemically similar species which may be isolated from clinical material. 相似文献

Cryptococcal osteomyelitis is extremely rare and almost always occurs in immunocompromised patients. We describe a case of osteomyelitis due to Cryptococcus neoformans involving both scapula and rib in an immunocompetent and previously healthy patient. The patient received treatment with amphotericin B deoxycholate and flucytosine for 4 weeks, followed by oral fluconazole 400 mg per day for 8 weeks and 200 mg per day for 9 months. The 12-month course of antifungal therapy resulted in complete clinical recovery and undetectable serum cryptococcal antigen. Cryptococcal osteomyelitis should be suspected in any immunocompetent patient with osteolytic lesions on radiological images. 相似文献
