BACKGROUND: Involvement of the female genital tract by Darier's disease, an unusual genodermatosis, is uncommon, and the manifestation of the disease in a cervicovaginal smear is exceptionally rare. CASE: A 39-year-old woman had an abnormal Pap smear caused by involvement of the female genital tract by Darier's disease. Cytologic examination showed features consistent with a low grade squamous intraepithelial lesion, but during a biopsy it was found to be vaginal involvement by Darier's disease. CONCLUSION: The correct interpretation of cytologic findings is not possible when the diagnosis of Darier's disease is not known since a low grade squamous intraepithelial lesion cannot be ruled out. This case underlines the importance of knowing the patient's medical histoiy in any moment of medical attention.  相似文献

Paget's disease (osteitis deformans) is characterized by localized deformation of bone leading to structural abnormalities with secondary pain, fractures and nerve compression. A Paget's patient with exophthalmos, a displaced globe, restricted muscle fields, diplopia and superior oblique entrapment secondary to deformation of the frontal bone is presented. The clinical features, ocular complications and treatment of Paget's disease is discussed.  相似文献

Seizures or convulsions that occur during anaesthesia in veterinary patients are infrequently reported in the literature. Consequently, the incidence of such events is unknown. Several drugs commonly used in clinical veterinary anaesthesia have been shown to induce epileptiform activity in both human clinical patients and experimental candidates. The present case report describes convulsions in a four-year old male Bernese mountain dog during maintenance of anaesthesia with isoflurane after premedication with acepromazine and methadone followed by co-induction with propofol and ketamine. The dog had no history of previous convulsions. The use of several sedative and anaesthetic drugs makes it difficult to find one single causative pharmaceutical.  相似文献

Retrograde ejaculation and hypothyroidism were diagnosed in a 19-mo-old Labrador retriever. The retrograde ejaculation was reversed following the administration of the sympathomimetic agent, pseudoephedrine hydrochloride, at a dose of 4 mg/kg per os given 1 and 3 h before semen collection. Antegrade ejaculation failed to occur after normalization of serum thyroid hormone levels by thyroxine supplementation. The pathophysiology of retrograde ejaculation is reviewed.  相似文献

The authors report a case of culture-proven disseminated American muco-cutaneous leishmaniasis caused by Leishmania braziliensis braziliensis in an HIV positive patient. Lesions began in the oropharynx and nasal mucosa eventually spreading to much of the skin surface. The response to a short course of glucantime therapy was good.  相似文献

Background

In the Indian subcontinent, about 200 million people are at risk of developing visceral leishmaniasis (VL). In 2005, the governments of India, Nepal and Bangladesh started the first regional VL elimination program with the aim to reduce the annual incidence to less than 1 per 10,000 by 2015. A mathematical model was developed to support this elimination program with basic quantifications of transmission, disease and intervention parameters. This model was used to predict the effects of different intervention strategies.

Methods and Findings

Parameters on the natural history of Leishmania infection were estimated based on a literature review and expert opinion or drawn from a community intervention trial (the KALANET project). The transmission dynamic of Leishmania donovani is rather slow, mainly due to its long incubation period and the potentially long persistence of parasites in infected humans. Cellular immunity as measured by the Leishmanin skin test (LST) lasts on average for roughly one year, and re-infection occurs in intervals of about two years, with variation not specified. The model suggests that transmission of L. donovani is predominantly maintained by asymptomatically infected hosts. Only patients with symptomatic disease were eligible for treatment; thus, in contrast to vector control, the treatment of cases had almost no effect on the overall intensity of transmission.

Conclusions

Treatment of Kala-azar is necessary on the level of the individual patient but may have little effect on transmission of parasites. In contrast, vector control or exposure prophylaxis has the potential to efficiently reduce transmission of parasites. Based on these findings, control of VL should pay more attention to vector-related interventions. Cases of PKDL may appear after years and may initiate a new outbreak of disease; interventions should therefore be long enough, combined with an active case detection and include effective treatment.  相似文献

The authors value the sensibility and the advantage of the different serological tests for the diagnosis of canine leishmaniasis (immunodiffusion, complement fixation and immunofluorescent tests) and give the results obtained from an epizoological survey carried out on dogs in the province of Foggia (Italy). The immunofluorescent test, whose positivity sera titre has fixed at the diluition of 1:10, resulted the most appropriate. In more than 400 animals examined, all from the 50 communes of the province of Foggia, the infection level of the dog by leishmania resulted to be 7.42%. If the three geographical zones, in which the province has been subdivided, are considered, this level varies from 10.21% for the subjects from the Gargano promontory, to 6.89% for those of the Subapennine Dauno, and to 5.55% for those of the Apulia plateau.  相似文献

Extranodal NK/T cell lymphoma, nasal type, is an Epstein–Barr virus-associated lymphoma that most commonly involves the nasal cavity and upper respiratory tract. Lung involvement by NK/T cell lymphoma is rare and seldom reported in the literature. We describe the unusual case of a 41-year-old male with NK cell lymphoma, nasal type, who presented with massive secondary lung involvement 2.5 years after the detection of a retroperitoneal mass. The diagnosis was made by open lung biopsy. Despite aggressive treatment, the patient died shortly after the initiation of therapy. Lung involvement by NK/T cell lymphoma occurs most commonly as part of widely disseminated disease and carries a poor prognosis for the patient. Novel agents and innovative therapies need to be developed for this aggressive lymphoma.  相似文献

This paper reports on a canine angiosarcoma, presenting as an "undifferentiated metastasizing tumor". A 14-year-old female Cocker Spaniel was referred to the University of Extremadura Veterinary Clinic for clinical examination after suffering rapid deterioration, with chronic cough, anorexia and cachexia. One week after clinical examination, the dog died of right congestive heart failure and ventricular arrhythmia. Blood counts revealed lymphopenia and platelet depletion. The biochemistry profile was within normal limits, except for a drop in blood urea nitrogen. Cytological evaluation of liver and spleen biopsies revealed clustered anaplastic cells that lacked convincing tissue differentiation. Major findings at necropsy were enlarged spleen and multiple, beige to dark-red nodules ranging from 0.5 to 3 cm in diameter in the heart, lung, liver and spleen. At histological examination, multiple nests of anaplastic epithelioid cells were found in sections from all affected organs. Immunohistochemistry revealed widespread expression of CD31 and Factor VIII-related antigen. The neoplastic cells were negative for CD 18. The diagnosis of epithelioid angiosarcoma, localized in the myocardium, lung, liver and spleen was made. The primary site of the neoplasm could not be determined.  相似文献

Synovial sarcoma (SS) is a mesenchymal tumor which generally affects the soft tissues of the extremities. Primary pleural synovial sarcoma (PPSS) is a very rare and aggressive subtype of SS. A 73-year-old male patient presented with chest-back pain and dyspnea. Hypermetabolic diffuse pleural lesions were detected in 18F-FDG PET/CT performed after pleural nodular thickenings were observed on CT. As the result of the molecular analysis performed in the excisional biopsy, SYT-SSX mutation was detected and the patient was diagnosed as SS. Pazopanib treatment was commenced. We are reporting a very rare case of PPSS with diffuse pleural involvement.  相似文献

BACKGROUND: Skin biopsy and scrape smear examination are the two most commonly employed investigatory techniques in the diagnosis of cutaneous leishmaniasis. Although cases Leishmania lymphadenitis are reliably diagnosed with fine needle aspiration (FNA) cytology, it has not attained popularity in the diagnosis of cutaneous leishmaniasis, and only a few reports are available. CASE: A 6-month-old Kuwaiti child presented with a skin lesion on her left forearm of five months' duration. Both scrape smears and FNA were performed from the lesion. FNA cytology smears showed a rich population of inflammatory cells predominating in lymphocytes and histiocytes and epithelioid cell granulomas. The amastigote forms of Leishmania were noted on the smears. The scrape smears were nondiagnostic. CONCLUSION: FNA cytology can be reliably used in the diagnosis of cutaneous leishmaniasis, especially in dry lesions, where scrape smears are likely to be nondiagnostic.  相似文献

BACKGROUND: Atrial myxoma is the most common primary intracardiac tumor. The diagnosis is generally primary intracardiac tumor, based on classical clinical findings coupled with echocardiographic or magnetic resonance image findings demonstrating a cardiac mass. CASE: Unsuspected atrial myxoma was found in a woman who had been diagnosed with invasive lobular carcinoma of the breast. The echocardiographic findings in the presence of fever favored a clinical working diagnosis of infective endocarditis complicating a suspected cardiac metastasis. While intraoperative frozen section examination could not rule out metastatic invasive lobular carcinoma, cytologic touch imprint findings were diagnostic of myxoma. This appears to be the first report of concurrent breast carcinoma and atrial myxoma. To our knowledge, this is also the first report of intraoperative cytologic diagnosis of cardiac myxoma. CONCLUSION: In myxoma cases with a complicated clinical setting in which frozen section examination may be equivocal, intraoperative cytologic examination may be a useful diagnostic tool.  相似文献
