[Study on patient satisfaction with the treatment of mycosis on the extremities with terbinafine (SETTA)].

INTRODUCTION: The SETTA study is an open-label, multicenter, prospective, observational study carried out in order to evaluate satisfaction with the treatment of mycosis on the extremities with terbinafine. METHODS: Patients clinically diagnosed with tinea pedis or tinea unguium after a single visit were recruited. Follow up was through a questionnaire that the patient was to send back. The two groups were statistically compared by means of three analyses: descriptive, effectiveness and safety. RESULTS: In the effectiveness analysis, significant differences were observed in the evolution of the tinea, the overall score and degree of adherence to the treatment, with these being more positive in the group with tinea pedis. In the safety analysis, adverse events, none of them serious, were reported in 24 patients. CONCLUSIONS: This study reflects a high degree of satisfaction and safety in the use of terbinafine to treat patients with mycosis on the extremities.

Pulmonary mycosis in AIDS.

We retrospectively reviewed our series of 35 pulmonary mycosis in patients with AIDS, observed from 1987 to 1999, to correlate the imaging and pathologic findings. We further evaluated the frequency of fungal pneumonia before and after the use of a highly active antiretroviral therapy (HAART). Early recognition of pulmonary mycosis is imperative in these patients and improved survival can be achieved with early CT detection and prompt institution of high-dose antifungal therapy.

Allergic bronchopulmonary mycosis to Fusarium vasinfectum in a child.

BACKGROUND: A 12-year-old boy with asthma and 6 years of recurrent pneumonias who had normal serum immunoglobulin concentrations was suspected of having allergic bronchopulmonary aspergillosis (ABPA). OBJECTIVE: To search for and secure a fungal etiology for a child who did not have ABPA but was suspected of having an allergic bronchopulmonary mycosis. METHODS: Immediate skin testing with fungal extracts, high resolution computerized tomography, and establishment of an ELISA procedure to detect serum IgE and IgG antibodies to Fusarium vasinfectum. RESULTS: Immediate skin reactivity was present for Fusarium, Cladosporium, Helminthosporium, and Aspergillus fumigatus. The ELISA demonstrated serum IgE and IgG antibodies to Fusarium vasinfectum 8.5 and 5.6 times nonatopic control sera. CONCLUSIONS: This 12-year-old with asthma has sufficient criteria for a diagnosis of allergic bronchopulmonary mycosis (ABPM) to Fusarium vasinfectum. Bronchiectasis was not present despite recurrent pneumonias and hemoptysis. This case appears to be the first pediatric example of ABPM to Fusarium species, a fungus more recognized for causing rotting of tomatoes and melons than human disease.

Mucor mycosis infection presenting as a non-healing ulcer in an immunocompromised patient.

Mucor mycosis is an uncommon saprophytic opportunistic fungus causing localized cutaneous infection associated with high morbidity and, on dissemination, high mortality. We report the case of an immunocompromised patient with an aggressively progressing, painful non-traumatic ulceration, unresponsive to standard treatment. Deep biopsies for haematoxylin and eosin staining and fungal culture revealed the characteristic broad non-septate irregular hyphae of mucor allowing introduction of the appropriate treatment. Infection with mucor mycosis must be considered in today's medical environment as the number of immunocompromised patients increases.

Transarterial coil embolization of the internal and external carotid and maxillary arteries for prevention of hemorrhage from guttural pouch mycosis in horses.

OBJECTIVES: To develop a transarterial coil embolization technique for occlusion of the internal carotid artery (ICA), external carotid artery (ECA), and maxillary arteries (MA) in normal horses and to evaluate this technique for prevention of hemorrhage in horses affected with guttural pouch mycosis. ANIMALS: Ten adult, normal horses and 4 horses with guttural pouch mycosis. METHODS: All horses had transarterial coil embolization of the rostral and caudal ICA, caudal MA, and rostral ECA. In 1 affected horse, an aberrant actively bleeding branch of the ECA was also occluded. Normal horses had a premortem angiogram, and were killed either at 1 or 2 weeks or 1, 2, or 3 months after the procedure. Specimens from the ICA, ECA and MA were evaluated by light microscopy. RESULTS: No surgical complications were observed, except 1 horse that developed laryngeal hemiplegia and 1 pilot horse that had embolization of the cerebral arterial circle. In normal horses, premortem angiography confirmed complete occlusion of all vessels, and coils were positioned as intended. All normal horses had partially maturing to mature, continuous thrombi occluding at the coils. In affected horses, no further episodes of epistaxis were observed. By day 60, all mycotic plaques had resolved without further treatment. Ophthalmic complications were not observed. CONCLUSION: Transarterial embolization provided a safe, rapid, and effective method for ICA, ECA, and MA occlusion in normal and affected horses. In affected horses, the technique was possible despite active bleeding, allowing adequate identification and occlusion of all sources of hemorrhage.

A multicenter, open-label clinical study of micafungin (FK463) in the treatment of deep-seated mycosis in Japan.

The efficacy and safety of micafungin (FK463), which is a new lipopeptide antifungal agent of the echinocandin class and is active against both Aspergillus and Candida species, were investigated in patients with deep-seated mycosis in this study. 70 patients were treated with micafungin 12.5-150 mg/d intravenously for up to 56 d. The overall clinical response rates were 60% (6/10) in invasive pulmonary aspergillosis, 67% (6/9) in chronic necrotizing pulmonary aspergillosis, 55% (12/22) in pulmonary aspergilloma, 100% (6/6) in candidemia, and 71% (5/7) in esophageal candidiasis. The response rates for patients with prior antifungal treatment which was considered ineffective or toxic, were similar to rates for patients without prior treatment. Mycological eradication was observed in patients infected with Aspergillus fumigatus, Aspergillus flavus, Aspergillus terreus, Aspergillus niger, Candida albicans, Candida glabrata, or Candida krusei. Adverse events related to micafungin were reported in 21 patients (30%), and there was no dose-related occurrence of any adverse event. It is concluded that treatment with micafungin as monotherapy seems to be effective and safe in patients with deep-seated mycosis.

Pulmonary mycosis in farmed deer: allergic zygomycosis and invasive aspergillosis.

During 1988, pulmonary mycosis was diagnosed in four of 116 farmed deer examined on suspicion of tuberculosis. The histopathology showed allergic bronchopulmonary mycosis in a red deer (Cervus elaphus) and the agent was identified as a zygomycete, probably Absidia corymbifera, by immunofluorescence staining. Three fallow deer (Dama dama) had invasive necrotizing mycotic pneumonia and progressive exudative mycotic alveolitis caused by Aspergillus fumigatus. In the red deer, weakness due to paratuberculosis had probably promoted the mycotic infection. The three fallow deer were bred on another farm, where predisposing factors included mouldy straw and incorrect management.

Emericella nidulans as an agent of guttural pouch mycosis in a horse.

A case is reported in a 9-year-old Anglo-Arab horse with guttural pouch mycosis caused by Emericella nidulans. Acute death occurred by exsanguination following erosion of the external carotid artery. Histopathological examination of the mycotic plaque demonstrated septate hyphae, conidial heads, hülle cells and mature cleistothecia containing characteristic ascospores. Specific identification was confirmed by culture. In accordance with previous reports, Emericella nidulans should be considered as the major agent of guttural pouch mycosis in Equidae.

Mycosis Fungoides-Like Atopic Dermatitis Represents a Th22-Dominant Inflammatory Endotype.

BACKGROUND: Early-stage mycosis fungoides (MF) often presents diagnostic challenges because of its clinical overlap with atopic dermatitis (AD). In clinical practice, we encountered a subset of patients with severe AD who fulfilled the MF diagnostic criteria yet remained clinically indistinguishable from AD and presented refractoriness to advanced therapies. We termed this ambiguous entity "mycosis fungoides-like AD" (mfAD) and sought to determine whether it represents malignant transformation or a distinct inflammatory endotype of AD. METHODS: Skin biopsies were obtained from 7 patients with AD and 11 patients with mfAD. We performed paired single-cell RNA sequencing and single-cell T-cell receptor sequencing analyses. Publicly available MF and AD datasets were integrated for comparative analysis. Spatial transcriptomic profiling was used to contextualize single-cell findings within the tissue architecture. RESULTS: Comparative transcriptomic analysis revealed that T cells in mfAD were aligned with those in AD and lacked genomic instability. High-resolution profiling showed that mfAD was characterized by oligoclonal Th22 expansion rather than a single dominant malignant clone. Notably, all patients with mfAD achieved rapid clinical remission with selective JAK1 inhibition, indicating the therapeutic response characteristics of inflammatory dermatoses. CONCLUSION: Our findings demonstrate that mfAD is not a true malignancy, but rather a Th22-driven inflammatory endotype of AD. These results redefine mfAD as an inflammatory subtype within the AD spectrum, providing a mechanistic explanation for both the "pseudo-monoclonality" that leads to MF misdiagnosis and the failure of dupilumab. This study establishes a rationale for the use of JAK inhibitors in precision medicine for this patient population.

[Clinical studies on mycosis especially deep-seated candidiasis in blood disorder patients].

Deep-seated mycosis is prominently increasing as a terminal infection in compromised hosts with malignant blood disorders or malignant tumors. Moreover, localized candidal abscess of visual organs has recently been reported in several laboratories. We investigated the occurrence of deep-seated mycosis in 105 autopsied cases with blood disorders in our clinic from 1980 to 1987. Forty-four of those cases had died of various infections, and 80% of them were fungal infections. More than half of the fungal infections were aspergillosis. Deep-seated candidiasis was recognized in 10 cases, 6 of which were systemic candidiasis, the average duration of neutropenia below 500/mm3 was 19.7 days that of lymphopenia was 36.5 days. Two cases were complicated with GI-tract ulcer, and involved with hepatic candidiasis. On the other hand, in the 4 cases of localized candidial abscess, the duration of neutropenia was 58.5 days and that of lymphopenia was 28.8 days. These four cases were complicated with GI-tract ulcer. Histologically, Candida spp. were recognized at the bottom of the ulcer and invasion by inflammatory cells or tumor cells was found in the portal vein. We surmised that GI-tract ulceration is a very important complication of hepatic candidiasis or liver abscess, and the occurrence of localized candidiasis seems to depend on the duration and severity of neutropenia.

[Deep-seated mycosis in patients with solid-organ transplantation--a study of autopsied cases in the United States].

Autopsies with solid-organ trans plantation (SOT) in UCLA Medical Center were reviewed, especially focussing on the deep-seated fungal infection and the incidence of fungal infections, causative fungi, and organs involved were evaluated. Deep-stated fungal infections were demonstrated in 21.0% of the patients with SOT. The incidence of fungal infections were 26.1% in kidney transplantation, which was the highest rate in SOT autopsies we reviewed, 25.0% in liver transplantation, 14.3% in lung transplantation, and 13.2% in heart transplantation. And the most common causative fungi were Aspergillus species, seen in 70.6% of SOT autopsies. In contrast, Candida species were observed in 25.5%. In addition, the incidence of deep-seated mycosis has been increasing since 1992, this was parallel to the increase of aspergillosis, most of which were found as a generalized spreading. In contrast, candidal lesions, were almost limited to the digestive tracts. The above suggests that from this standpoint, improvement of prophylactic and therapeutic technique against aspergillosis is the greatest problem in deep-seated mycosis in SOT patients.

Occlusion of the internal carotid artery by means of microcoils for preventing epistaxis caused by guttural pouch mycosis in horses.

Occlusion of the internal carotid artery by insertion of intravascular platinum microcoils for guttural pouch mycosis was experimentally evaluated in 9 healthy adult Thoroughbred horses. The internal carotid artery was ligated to its origin, and an arteriotomy was made distal to the ligature, which was then occluded by insertion of the microcoil approximately 13 cm distal to its origin. Cessation of blood flow was determined visually and by angiography at the arteriotomy site. Six horses were evaluated for complication clinically and by endoscopy after surgery. One horse was necropsied after 30 days of surgery for histological evaluation of artery thrombus formation. In the other 3 horses, the blood flow of the right internal carotid artery was monitored, before and after microcoil occlusion of the left internal carotid artery. One or 2 microcoils stopped blood flow within a few minutes. No other abnormal findings were observed clinically. Thrombus was observed in the occluded segment of 1 horse 30 days after insertion; but no abnormalities were detected. The blood flow in the right internal carotid artery increased by approximately 28-58% after occlusion of the left internal carotid artery. This microcoil vascular occlusion technique causes an effective thrombosis, and based on experimental studies and clinical application in 2 horses with epistaxis due to guttural pouch mycosis, this technique would appear to be safe and efficacious.

Sinobronchial allergic mycosis: the SAM syndrome.

We contend that the presence of concomitant allergic fungal sinusitis (AFS) and allergic bronchopulmonary mycosis in the same patient represents an expression of the same process of fungal hypersensitivity in the upper and lower airways. We have termed this process the SAM syndrome, an acronym for sinobronchial allergic mycosis. Diagnostic criteria have been established for the SAM syndrome, and the clinical characteristics of one previously unreported and four previously reported patients have been tabulated. Patients with the SAM syndrome have chronic sinusitis involving multiple sinuses, asthma, immediate cutaneous reactivity to fungal allergens, peripheral eosinophilia, and radiographic evidence of bronchiectasis. Total serum IgE levels are usually elevated as well. A variety of chest radiographic abnormalities may occur, ranging from mass lesions to diffuse pulmonary infiltrates and even normal findings on chest radiographs. Patients present for an evaluation of either sinus or lung disease and, at that time, demonstrate no clinical features that distinguish them from patients with isolated sinus or lung disease. All patients reported to date have had clinical responses to therapy with corticosteroids. We postulate that SAM is underdiagnosed in patients with AFS, a disease recently reported from medical centers in the southeastern and western United States. Moreover, since our patient had a mutation in the cystic fibrosis transmembrane conductor regulator (CFTR) gene, we further hypothesize that CFTR gene mutations may play an important role in the pathogenesis of the SAM syndrome.

[Refractory mycosis in ophthalmology].

Ophthalmological mycosis were seen as blephlitis, conjunctivitis, keratitis, orbititis, endophthalmitis. These dideases were almost hard to diagnose and were rare and refractory to treatment. Among them, keratomycosis was most frequent and relatively refractory to treatment. Orbit mycosis was rare but most refractory to treatment. Almost of them were fatal in our knowledge.

[Invasive mycosis in solid organ transplantation].

Invasive mycosis in solid organ transplantation is mainly caused by Candida and Aspergillus, and its risk is higher in small bowel, liver, pancreas, and lung transplantation. Although limited analyses propose not a few risk factors for invasive mycosis in respective transplanted organs, the efficacy of prophylactic use of antifungal agents or preemptive treatments based on the information is not fully supported by prospective randomized controlled clinical data. The final guideline should be helpful for tailor-made evidence-based management based on the stratification of patients by pretransplant, surgical, immunosuppressive and organ specific characteristics. The process of repeated proposals and verification in a large number of patients is necessary.

Candida species and crop mycosis in broiler chickens.

A mycological survey of the crops of approximately 100 healthy birds from each of 6 grow-out operations revealed that the incidence of Candida in the crops ranged from 17.4 to 51.5% with a mean value of 32.3%. The population of Candida in the crops of birds found positive was of low magnitude in the majority of the chickens examined. Of the 573 birds examined in this study less than 1% exhibited visible lesions attributable to Candida. C. albicans comprised 95% of the isolates while C. ravautii, C. salmonicola, C. gulliermondi, C. papapsilosis, C. catenulata and C. brumptii comprised the remainder. The incidence and number of Candida in the crop was related apparently to management practices on the farm. The crops from four field outbreaks of crop mycosis were also studied. Three of the four cases of crop mycosis were characterized by multiple strains of C. albicans in the crop. In one case, C. parapsilosis also was isolated from the crop.

[Psychosocial risk factors in vulvovaginal mycosis. A multivariate long-term study].

The results of a multivariate logit-analysis of n = 9098 (female) patients of a gynecologic practice (from 1991 to 1994) confirm the relevance of psycho-social factors like employment, being married, smoking etc. on the incidence of the vulvovaginal mycosis. By the statistical results the studied factors can be rank-ordered from "smoking" as the most relevant to "virginity" as the most irrelevant factor. Surprisingly sexual contact and using oral contraception had no relevance. A check-list using factor-combinations enables to discriminate 48 types of female with different risk of incidence. The results of the study are in accordance with the following hypothesis: In most cases stress, induced by the psycho-social situation of the female and weakening the immune system, is the only responsible factor for the incidence of vulvovaginal mycosis.

Trichomonosis of the oral cavity complicated by mycosis.

Protozoa and fungi of the oral cavity, although frequently occurring and connected to considerable clinical adverse effects, are as yet insufficiently known. The aims of the study were (i) to estimate the prevalence of common invasions of Trichomonas tenax and fungi, (ii) to associate the symptoms with the diagnosis of trichomonosis complicated by mycosis, and (iii) to determine trichomonacidal properties of ornidazole, tinidazole and metronidazole. A sample of 936 dentist patients with different diagnoses were included in the study. The collected material consisted of rinsings, with simultaneous application of selective media, different for protozoa or fungi cultures. Using ornidazole, tinidazole and metronidazole, we examined in vitro their influence on 30 strains of T. tenax. Among the examined patients T. tenax was found in 90 cases including 85 cases where it occurred together with fungi, on the basis of which diagnosis of trichomonosis complicated by mycosis of the oral cavity was established. It was the most frequent in patients with leukoplakia and lichen Wilsoni. We recorded a statistically significant association for T. tenax with fungi and xerostomia, burning sensation, periodontal pockets and denuded teeth. T. tenax was never found in patients with caries and with aphtha recidivans. The curves of ornidazole activity were obtained within the solution range of 130-4350 micrograms/ml; the curves of tinidazole activity within the concentration range of 500-16870 micrograms/ml; metronidazole in the highest concentration killed from 5 to 100% of the population of all strains.
