[Acquired ocular toxoplasmosis and immunosuppression of tumoral thymic origin].

A rare case of acute bilateral unifocal chorioretinitis in a 24 years old man is described. The patient had been followed for more than 3 years for a benign thymoma, detected by systematic radiography, that was initially operated on with success. Later, after recurrence of clinical signs a second operation was performed that revealed local invasion of the tumor which was histologically identified as a benign, lymphoid thymoma. Serological data permitted us to attribute the lesions to a sub-acute ganglionary toxoplasmosis, contracted five months before any ocular localization. A treatment including local corticotherapy and oral pyrimethamine and sulfonamide was undertaken. Healing of the retinal lesions occurred slowly. A complete study of the patient's immunity revealed an important deficiency of cell-mediated functions. The problem of diagnosis of opportunistic chorioretinitis is discussed. In patients with impairment of cellular-type immunity, the following are commonly observed: herpes group viral diseases (including cytomegalic inclusion disease), fungus diseases (candida, aspergillus, mucormycosis, cryptococcus), and, rarely, toxoplasmosis. The presence of specific serum antibodies is the most important element in making a diagnosis, considering that the ophthalmoscopic appearance and clinical course may vary.

[100 years of dermatovenereology in Bosnia-Herzegovina].

The beginnings of dermatovenerology in Bosnia and Herzegovina are described in the paper in the chronological order. The first written documents, in an official health institution, date from the year 1846, when the Vakuf's Hospital was built in Sarajevo. In the national pathology the treatment of syphilis was priority, fungus diseases, pioderm, skin diseases and leprosy. In 1894 a modern (at that time) Regional Hospital was built up, opened in Sarajevo, 1894 with a Dermatovenerologic Department (60 beds). VIIIth German Dermatovenerology Congress took place in Sarajevo. The main subjects were: leprosy, pelagra, syphilis. In 1897 the first leprosium was built up here being the only one on the Balkans and this part of Europe. The post World War 2, 15 years were characterized by the prevention of syphilis, fungus diseases, pioderm and parasites. The scientific work started, publications came to existence, the authors originating from Bosnia. Later, the dermatovenerology departments in other towns were established (Mostar, Zenica, Bihać, Foca, Travnik, Bugojno), while Banjaluka and Tuzla, established clinics of their medical faculties, which had been opened in the towns. In 1992, the Dermatovenerology Clinic became one of the units of the Clinical Centre in Sarajevo.

Indoor mold, toxigenic fungi, and Stachybotrys chartarum: infectious disease perspective.

Damp buildings often have a moldy smell or obvious mold growth; some molds are human pathogens. This has caused concern regarding health effects of moldy indoor environments and has resulted in many studies of moisture- and mold-damaged buildings. Recently, there have been reports of severe illness as a result of indoor mold exposure, particularly due to Stachybotrys chartarum. While many authors describe a direct relationship between fungal contamination and illness, close examination of the literature reveals a confusing picture. Here, we review the evidence regarding indoor mold exposure and mycotoxicosis, with an emphasis on S. chartarum. We also examine possible end-organ effects, including pulmonary, immunologic, neurologic, and oncologic disorders. We discuss the Cleveland infant idiopathic pulmonary hemorrhage reports in detail, since they provided important impetus for concerns about Stachybotrys. Some valid concerns exist regarding the relationship between indoor mold exposure and human disease. Review of the literature reveals certain fungus-disease associations in humans, including ergotism (Claviceps species), alimentary toxic aleukia (Fusarium), and liver disease (Aspergillys). While many papers suggest a similar relationship between Stachybotrys and human disease, the studies nearly uniformly suffer from significant methodological flaws, making their findings inconclusive. As a result, we have not found well-substantiated supportive evidence of serious illness due to Stachybotrys exposure in the contemporary environment. To address issues of indoor mold-related illness, there is an urgent need for studies using objective markers of illness, relevant animal models, proper epidemiologic techniques, and examination of confounding factors.

[Detection of phospholipidolytic Candida albicans isolated from saliva of children with Down's syndrome].

The childhood is one of the most propitious period of the life to the occurrence of infection by yeasts of the genus Candida. In children with Down's syndrome, besides the predispose factors to bucal candidiasis; macroglossia, bucal muscular incompetence, frequent respiratory diseases, motor difficulty and immunologic deficit are mentioned as additional elements for this fungus disease. It was verified that the children attacked by this syndrome have much more strains of Candida than other children. The aim of this study was to detect the prevalence of phospholipase producer, Candida on the saliva of children with Down's syndrome. Candida albicans was the only identified specie of Candida. The phospholipase production was found in isolated strains from both of study and control. However, the isolated strains of the group of children with Down's syndrome have strongly present phospholipidolitic.

Systemic fungal infections: diagnosis and treatment. I. Histoplasmosis.

Histoplasmosis is a fungus disease of nearly worldwide distribution. Because of its wide distribution and tendency to be endemic near large cities, it is the most common systemic mycosis in the United States, with an estimated 500,000 new infections per year. Although millions of persons in the United States have been infected with this fungus, few show signs of disease. Histoplasmosis has emerged as an important opportunistic infection in immunocompromised patients, including those with AIDS. This review of histoplasmosis builds upon basic descriptions found in standard texts, incorporating important recent observations.

[A study of total IgE in inflammatory pathologies of the eye anterior segment].

The paper contains data on comparative research of the IgE content in blood serum and lachrymal fluid in patients with ophthalmoherpes and with other inflammatory diseases of the eye. A higher IgE level was found in blood serum and lachrymal fluid in cases of ophthalmoherpes as well as in lachrymal fluid in cases of allergic, Chlamydia and fungus diseases of the eye. The data obtained can be used in the diagnostics of allergic eye diseases as well as in elaborating complex treatment methods for herpetic, Chlamydia and fungus lesions of the anterior eye segment. A detection of the local allergenic effect of acaricide drugs exerted on the conjunctiva and eyelids makes it obligatory to consider the above fact while treating patients with demodectic blepharoconjunctivitis.

[Manifestations of primary vasculitis in the ENT region].

The primary ANCA associated vasculitides, Wegener's granulomatosis (WG), Churg Strauss syndrome (CSS) and microscopic polyangiitis (MPA), frequently affect the ENT region. For several reasons WG is of special significance for the otorhinolaryngologist. First, disease activity limited to the upper respiratory tract (localized WG) often proceeds the systemic vasculitis (generalized WG). The early diagnosis therefore has decisive consequences for stage adapted therapy. Second, in most cases (nearly 80%) WG is diagnosed histologically on biopsy specimens from the ENT region. During the initial phase of WG this is of diagnostic relevance, because at this stage the serologic parameters (acute-phase proteins) usually have a normal value and PR3-ANCA is (still) negative in 2/3 of the patients. Third, in many cases recurrences reveal increased activity in the ENT region, or start in this area. Clinically in most cases chronic rhinosinusitis with crusting and epistaxis is seen, sometimes with septal perforation and/or saddle nose. Apart from this there are often unclear middle ear symptoms with recurrent effusions and the inner ear is sometimes also affected. Laryngeal manifestations are typically located in the subglottic area and lead to subglottic stenosis. In the differential diagnosis, diseases in which epitheloid cell granulomas occur, such as sarcoidosis and TBC, need to be considered, but also foreign body granulomas and fungus diseases. Finally malignant tumours, especially malignant lymphomas, have to be ruled out.

Magnetic resonance imaging in the evaluation of nose and paranasal sinus disease.

Fifty patients with a wide range of sinus disease have been examined by magnetic resonance. These included congenital conditions, inflammatory and allergic sinus disease, fungus infection, and both necrotising and non-necrotising granulomas. A variety of benign and malignant tumours have been investigated, including eight examples of juvenile angiofibroma and 19 malignant sinus tumours. This experience of magnetic resonance scanning has shown that it is superior to computed tomography in showing the extent of malignant disease and, provided the correct pulse sequences are employed, it is always possible to distinguish tumour from retained secretion or inflamed mucosa. The extent of intracranial invasion can also be optimally demonstrated. One of the advantages of the method is the direct three-plane imaging and multislice technique, which gives total coverage of the head and neck for the assessment of malignant disease. Tissue diagnosis in the paranasal sinuses is less important than the demonstration of tumour extent and distribution. Only one tumour (juvenile angiofibroma) showed diagnostic spin-sequence characteristics, and no differentiation was observed between malignant tumours of epithelial and mesenchymal origin. The major drawback of magnetic resonance is the poor demonstration of bone and calcification in the sinuses, so that in some patients the scans need to be augmented by computed tomography studies.

Magnetic resonance imaging of the nose and paranasal sinuses.

Seventy-five patients with a wide range of sinus disease have been investigated by magnetic resonance (MR): these included congenital conditions, allergic and inflammatory sinus disease, fungus infections, and the necrotizing granulomata. In addition, a variety of benign and malignant tumours have been examined, and in the more recent sinus malignancies the paramagnetic contrast agent, Gadolinium (Gd) DTPA (Schering Health Care) has been used. This experience of magnetic resonance scanning has shown that it is superior to computed tomography in demonstrating the extent of malignant disease in the nose and sinuses; most especially when Gd DTPA is used, reaching an accuracy of over 96% by biopsy correlation. An additional advantage of this technique is the wide coverage of the head and neck for the assessment of malignant disease, provided by direct 3 plane imaging and the multislice facility. The main disadvantage of magnetic resonance of the sinuses is the poor demonstration of calcification and bone. For this reason the MR scans may need to be augmented by high resolution CT performed specifically to show bone detail.

[A histiocytosis X without histological findings: a new entity of histiocytosis X].

Histiocytosis X is a disorder of the reticuloendothelial system with manifestations usually present in the form of one of three entities, namely; Letterer-Siwe disease, Hand-Schüller-Christian disease and eosinophilic granuloma of the bone. A 32-year-old female was admitted to our hospital in July 1990 because of a bilateral diffuse granular abnormal shadow in the chest. She had a history of bilateral pneumothorax in July 1987. She had been suffering from diabetes insipidus since October 1987, and amenorrhea since January 1989. Miliary tuberculosis, fungus disease, pneumoconiosis, sarcoidosis and collagen disease of the lung were excluded by laboratory examinations, and by observation of the clinical course. Histiocytosis X often combines pneumothorax, diabetes insipidus, amenorrhea and an abnormal radiograph of the chest. We suspected this case was one of Histiocytosis X. But, in her lung biopsy, neither Langerhans cells nor Birbeck granules were found. Furthermore S100 protein immunoperoxidase stain was negative. Therefore, we posit the existence of a new and different subtype of Histiocytosis X without histological findings.

Effect of a virus on accumulation of a tissue-specific cell-surface protein of the fungus Cryphonectria (Endothia) parasitica.

Hypovirulence and decreased sporulation of the plant pathogenic fungus Cryphonectria (Endothia) parasitica is caused by double-stranded (ds)RNAs. These symptoms of dsRNA infection are correlated with down-regulation of at least nine major fungal polypeptides. One of the regulated polypeptides was purified to homogeneity and antibody to it was prepared. This polypeptide (cryparin) has a -glycine-serine-repeating sequence near the amino-terminal end that is typical of structural proteins and has properties of a lectin. Antibody-staining showed that this 18.6-kDa polypeptide is specific to aerial hyphae and fruiting bodies and that it accumulates in large amounts on hyphal cell surfaces. The dsRNA affects accumulation of this protein, both in the fugal hyphae and in the growth medium. Cryparin is similar in physical properties to those of the putative phytotoxin cerato-ulmin produced by the Dutch elm disease fungus. Toxicity of cryparin is not detectable, but the striking similarities between the physical properties and locations of accumulation of cryparin and cerato-ulmin in fungal fruiting structures suggest either conservation of structure or convergent evolution in function of these two proteins.
