The skin window test in rhinoscleroma.

The skin window test was applied to evaluate the state of immunity in patients with rhinoscleroma. The use of the patient's own Klebsiella micro-organisms as antigen led to a negligible change in the percentage of lymphoblasts, whereas the use of foreign Klebsiella micro-organisms as antigen resulted in a pronounced change. This finding indicates an impaired cellular immune response. Application of Klebsiella microorganisms as antigen to normal subjects led to a comparatively high percentage of lymphoblastic transformation. This finding suggests the possible use of a standard Klebsiella antigen as a vaccine. The possible use of the skin window test to identify people with deficient T lymphocyte function is discussed as well as its use in monitoring the efficacy of such a vaccine in influencing the cellular immune response.

Scleroma (rhinoscleroma) in a Nigerian maxillo-facial practice. Review and case reports.

Scleroma (rhinoscleroma), a chronic granulomatous disease of the upper respiratory tract, is endemic within a confined distribution of geographic foci. Sporadic cases and those arising in poorly defined foci may be unexpected and difficult to diagnose. Three cases from a maxillo-facial unit in northern Nigeria are described, of which two simulated intranasal neoplasms and the third had atypical clinical features. These cases form the first substantial description of scleroma in Nigeria, a country that is part of an indefinite focus of the disease. The epidemiology, clinical features, pathology and diagnosis of scleroma are reviewed.

Rhinoscleroma: case report.

Rhinoscleroma is a chronic, granulomatous infection that most frequently affects the respiratory mucosa, especially the nasal cavity and eventually extending through the lower respiratory tract. The disease is endemic in some countries of Central America (El Salvador and Guatemala), Indonesia, India, Poland, Hungary, Russia and some African countries as well. It is a rare disease in South America. We report a 51-year-old male resident of a psychiatric institution in São Paulo presenting with progressive nasal obstruction, frontal headache, yellowish nasal discharge and a mass extruding through the right nasal vestibule. The present case report describes a Rhino-Sinus scleroma where histopathology was vital in the diagnosis. The patient was treated by surgical excision of the nasal mass followed by a course of ciprofloxacin. He has remained asymptomatic up to the last visit six months following treatment and has shown no evidence of recurrence.

Local iatrogenic complications in nasopharyngeal rhinoscleroma.

The possible role of surgical manipulation in inducing local spread and cicatricial complications in rhinoscleroma is illustrated by the three cases discussed in this paper. This is especially so where its occasional presentation as polypoid lesions of the lower respiratory tract may mimic other more sinister lesions and lead to unwarranted invasive procedures by the unsuspecting clinician. The infective nature of the lesions must be appreciated and confirmed microbiologically for appropriate drug treatment to be used. The benefits of minimal surgical intervention are illustrated in the third case.

Radiological diagnosis of rhinoscleroma--the 'palatal sign'.

This paper reports a characteristic radiological finding observed in seven cases of rhinoscleroma with nasal involvement. The soft palate exhibits a marked thickening at its attachment to the hard palate which tapers off towards its free edge. This new sign could be of help in the early diagnosis of this condition.

Rhinoscleroma.

We have described a case of rhinopharyngeal rhinoscleroma, and reviewed the clinical behavior and management of this disease. Selective long-standing antibiotic treatment was successful in halting the process. Treatment of the advanced cicatrix with carbon-dioxide laser vaporization yielded excellent results.

Alterations in the T-lymphocyte subpopulation in patients with rhinoscleroma.

T-lymphocyte subpopulations were studied in a group of patients with rhinoscleroma due to Klebsiella rhinoscleromatis. The data demonstrated that these patients had a significantly greater number of T-suppressor/cytotoxic lymphocytes than did clinically healthy individuals. This finding correlated with a diminished response to the T-cell mitogen concanavalin A. The evidence indicated that the T-cell response of these patients was decreased and may reflect the host's response to the bacterial invader, thus explaining the chronicity of the disease.

Rhinoscleroma with exophthalmos: a case report.

This is a report of a 20-year-old Nigerian man with a 15-year history of exophthalmos and nasal blockage caused by rhinoscleromatous. The diagnosis was made by histopathological examination of a biopsy specimen taken from the nasal passages. Despite protracted antibiotic therapy the patient experienced recurrent exophthalmos. Computerised axial tomography and sinus films showed the lesion to have invaded through the sinus passage into the orbit. Further histopathological examination of tissue removed at the time of surgical decompression also revealed rhinoscleroma. This appears to be the third report of rhinoscleromatous spread to the orbit.

Rhinoscleroma: a scanning electron-microscopic study.

Nasal biopsies from 6 patients with rhinoscleroma were studied by scanning electron microscopy. Numerous bacilli of different sizes were found on the epithelial surface. Few bacilli with thin spiral terminal cilia were seen over the surface of large protruding non-epithelial cells. These cells appeared to be the Mikulicz cells migrating from the tunica propria to the epithelial surface through small ulcerations. In the tunica propria, Mikulicz cells containing numerous bacilli were observed. In 4 patients, round bodies and long tubular structures were found on the epithelial surface. These bodies were suggested to be fungi, yet their exact nature and their relation to Klebsiella rhinoscleromatitis bacilli need further investigation.

[Rhinoscleroma with sinuso-orbitary invasion].

The authors present the case of an 11-year-old child with a slowly progressive tumoral invasion resulting in bilateral nasal obstruction, massive facial deformation, and an exophthalmos of the left eye. There was no impairment of the child's general health. The histological investigation revealed the presence of Mikulicz' cells and von Frisch's bacilli. The resultant diagnosis was rhinoscleroma.

Rhinoscleroma mimicking nasal polyposis.

Rhinoscleroma is increasing in incidence in the United States. It should be considered in patients who are immigrants from endemic countries and present with nasal polyposis that exhibits significant adherence to the nasal septum and relative sparing of the sinuses. Fluoroquinolones are emerging as the adjunctive antibiotic treatment of choice to complement surgical extirpation of the disease.

Rhinoscleroma--a diagnostic challenge.

Rhinoscleroma is a rare chronic granulomatous infection predominantly affecting the upper respiratory tract. The patient presented here exemplifies several features of the disease, including the fact that diagnosis may elude the clinician for years, and this delay may increase morbidity substantially. The most common initial complaint is nasal obstruction, and physical examination frequently reveals erythematous granular or nodular swellings covered with crusts. Its tumor-like appearance and local spread arouses suspicion of malignancy, but differential diagnosis also includes fungal infections and numerous granulomatous diseases. The classic histopathology consists of large vacuolated Mikuliz's cells and transformed plasma cells with Russell bodies. Numerous antibiotics have been used for treatment of this infection with varying degrees of success. Long-term follow-up is important because these patients can have numerous relapses. Geographic distribution is also discussed.

Laryngotracheobronchial involvement in a patient with nonendemic rhinoscleroma.

We report the first case of rhinoscleroma in an Israeli citizen, a former sailor with a transatlantic shipping company. Characteristic histologic changes from a tracheal biopsy and isolation of Klebsiella rhinoscleromatis from a blood culture after diagnostic bronchoscopy confirmed the diagnosis. Extreme delay in the diagnosis, a not uncommon feature in nonendemic areas, was associated with severe advanced laryngotracheobronchial disease. Treatment with quinolones was followed by significant improvement, but the patient died 1 month after presentation, apparently from upper airway obstruction.

[Rhinoscleroma. A case report].

Rhinoscleroma is a chronic, specific, inflammatory granulomatous condition of the nose and other structures of the upper respiratory tract. It is caused by the bacterium Klebsiella rhinoscleromatis. We report a case in a 29-year-old black male emigrant who consulted for a 2-year history of hoarseness, cough, and nasal discharge. The diagnosis was scleroma with nasal, laryngeal, tracheal, and bronchial involvement and ulcerating and necrotizing lesions that caused respiratory obstruction. Bacterial over-infection responded to treatment with third-generation cephalosporins and clindamycin. The sclerotic lesions responded well to treatment with ciprofloxacin. We review the clinical findings at different stages, diagnostic options, and several treatments.

[Rhinoscleroma with extramaxillary extension: report of a clinical case].

Rhinoscleroma is a chronic, granulomatous infection most frequently affecting the respiratory tract mucosa. The disease is endemic in some geographic areas and is sporadic in Italy, where medio-facial granulomatoses must be differentiated from malignant naso-sinus neoplasms. The present work describes a case of rhino-sinus scleroma with extramaxillary extension, defining the most important clinical characteristics and the treatment performed.

[An etiological and pathologic study of Rhinoscleroma].

OBJECTIVE: To investigate the clinicopathologic characteristics and mechanism of tissue injury caused by Klebsiella rhinoscleromatis (KR) infection. METHODS: Thirty-three cases of rhinoscleromas in the nasal and pharyngeal region seen in this hospital from Jan. 1980 to Mar. 2000 were studied retrospectively. Warthin-Starry (W-S) stain was used to study all cases. Five cases were studied further with transmission electron microscope. RESULTS: W-S stain revealed a great number of KR in Mikulicz cells within the granuloma. Electron microscopy demonstrated a number of phagosomes in the cytoplasm of Mikulicz cells where many KR were found. A small number of other organelles such as endoplasmic reticulums and lysozymes were squeezed to the side of cells. There were many granular substances on the surface of intracellular bacteria, which were not found on the extracellular KR. CONCLUSION: KR is a facultative intracellular bacteria that is able to resist the digestion of macrophages and to proliferate in them. Formation of granulomas and fibrosis in KR infiltrated regions is the major cause of tissue injury.

[Light and electron microscopy of rhinoscleroma (author's transl)].

The authors report the case of a 50 year old male patient whose rhinoscleroma, localized to the upper respiratory tract, was demonstrated by the isolation of Klebsiella bacilli and histologically. Electron microscopically the Mikulicz cells were characterized by fused vacuoles occupying the largest portion of the cytoplasm and displacing the damaged cytoplasmic organelles. Phagosomes and dense bodies reminiscent of Russel bodies also occurred in the Mikulicz cells, in the vacuoles of which formations representing Klebsiella rhinoscleromatis were demonstrated. A light halo was visible around some of these formations. It could not be, however, decided whether these halos represented the mucous sheath of the bacillus or an artifact only. In the plasmacells the authors observed the bag-like dilatation of the ergastoplasm and the presence of Russel bodies. Transitory forms were not seen among the plasma and Mikulicz cells. As a result of the treatment, Klebsiella disappeared from the nasal mucosa of the patient. The authors wish to follow by means of electron microscopy the changes of the granulation tissue and pathogens following antibiotic therapy.
