Table 9.1. Gross lesions of M. kansasii infection in rhesus monkeys included one to two pulmonary nodules, some containing yellow–green caseous material, and tuberculous-type lesions in the mediastinal lymph nodes (Valerio et al., 1979). Organisms are usually abundant on acid-fast stain in immunocompromised patients, but are rare in immunocompetent persons. Lady Windermeres Fächer (Lady Windermere’s Fan: A Play About a Good Woman) ist eine Gesellschaftskomödie in vier Akten des irischen Schriftstellers Oscar Wilde. An empyema is a purulent (infected) effusion. 1990;57:209-215. Another emerging concept is that of patient-to-patient transmission of M. abscessus in cystic fibrosis (CF) populations. Right middle lobe syndrome is usually encountered in older adults, with a predilection for women (see Lady Windermere syndrome). Lady Windermere syndrome: middle lobe bronchiectasis and Mycobacterium avium complex infection due to voluntary cough suppression. Unlike in adults, pulmonary NTM infection in infants and children is more likely to be associated with marked lymphadenitis and less likely to cause focal, destructive parenchymal disease. Dhillon SS, Watanakunakorn C. Lady Windermere syndrome: middle lobe bronchiectasis and Mycobacterium avium complex infection due to voluntary cough … There were no gross or microscopic lesions, but M. gordonae was isolated from the mediastinal lymph nodes, spleen, and/or liver. Epub 2016 Apr 29 doi: 10.1016/j.arbres.2016.03.005. 7.59). Infections have been observed in dental clinics, physiotherapy and hydrotherapy suites, as well as postcosmetic surgery. 30(3):572-5. There was no malignancy. These organisms enter hosts via the gastrointestinal tract or the lungs. 5. The Lady Windermere syndrome is a special form of pulmonary MAC seen primarily in middle-aged and elderly women. Following surgery, culture from sputum obtained 2 weeks earlier grew Mycobacterium avium complex (MAC), and subsequent culture results clearly indicated infection with this species. Clinical significance of some NTM remains questionable. For example, the NTM pathogens do not cause the same sequence of primary or postprimary disease, and systemic dissemination does not occur except in the immunocompromised patient. Culture and PCR may be useful diagnostic adjuncts. Lingular and middle lobe infiltrates in an elderly woman. Although MAC can commonly be isolated from sputum, pulmonary disease associated with MAC is rare. MAC is also acquired in conjunction with other underlying diseases such as Cystic Fibrosis, lung issues caused by heavy smoking, excessive alcohol consumption, and Acquired Immune Deficiency Syndrome (AIDS). Reich JM Lung 2018 Aug;196(4):377-379. Minimal ptosis, with mild thickening of the eyelid and little or no hyperemia, was observed. In general, NTM pulmonary infection may present as air-space filling processes or “pneumonia,” as obstructing endobronchial lesions,180 or as a compressive peribronchial lymphadenopathy.181 Intrathoracic lymphadenitis without airway involvement has also been described. In … Other indications for surgery are the same as for regular TB. KAREN L. CHANG, ... LAWRENCE M. WEISS, in Modern Surgical Pathology (Second Edition), 2009. A rare morphologic manifestation of mycobacterial infection is the so-called spindle cell inflammatory pseudotumor (Fig. The liver is involved in more than 50% of disseminated cases. No, I can't shake hands with you. MAC infection is acquired through inhalation or ingestion of the organism, with most infections in HIV-infected patients believed to occur through colonization and invasion of the gut mucosa. In a breeding colony of rhesus monkeys, 71 monkeys developed positive tuberculin reactions, and 60 monkeys were culture positive for M. kansasii (Valerio et al., 1979). Surgery is indicated for complications of TB, with the most common indication in the United States being MDR-TB with destroyed lung and persistent cavitary disease. Hot tub lung . In this case prophylaxis or treatment should be considered. For those patients with documented MAC infection, treatment regimens include clarithromycin, ethambutol, rifabutin, ciprofloxacin, ofloxacin, or amikacin. Alerts and Notices Synopsis Mycobacterium avium and intracellulare (MAI) is an acid-fast atypical mycobacterium complex that is ubiquitous. Patients with this syndrome experience chronic cough, sputum production, weight loss, fever, lethargy, and night sweats. Treatment typically lasts at least 12 months. (2012). The isolation of M. kansasii from sputum is always considered diagnostic of pulmonary disease, since colonization is uncommon. Pathogenesis of Lady Windermere syndrome. The Lady Windermere syndrome is a special form of pulmonary MAC seen primarily in middle-aged and elderly women. Some patients, particularly those who are immunocompetent, reveal the presence of discrete, epithelioid granulomas with associated neutrophils and lymphocytes. Examination of an induced sputum smear showed acid-fast bacilli. This can occur in those exposed to water vapour containing MAC (commonly in poorly maintained indoor hot tubs or swimming pools). Several aspects of NTM epidemiology in healthcare are unclear and warrant further investigation. At physical examination hepatomegaly, splenomegaly and lymphadenopathy are very common, and elevations of serum alkaline phosphatase, lactate dehydrogenase and anemia are the most frequent laboratory findings. Nosocomial NTM Sources, Transmission Routes, and Risk Factors, Sources of nontuberculous mycobacteria in the healthcare environment, Transmission routes of nosocomial nontuberculous mycobacteria, Droplets/aerosolization from water, heater–coolers, or humidifiers, Patient risk factors for nosocomial nontuberculous Mmcobacterial infections, Rejuvenation surgery/fat grafting or liposuction. The resected specimen was positive for acid-fast bacteria. © 2020 MJH Life Sciences and Patient Care Online. The objective of this study is to ascertain its frequency … Computed tomographic diagnosis of Mycobacterium avium-intracellulare complex in patients with bronchiectasis. Two monkeys were euthanized and necropsied. Lady Windermere es la protagonista de Lady Windermere’s fan (El abanico de Lady Windermere, 1892), comedia de enredos de Oscar Wilde (3) donde se habla de la costumbre socialmente inaceptable en la sociedad victoriana Chest 1992; 101:1605. The rapid growing mycobacteria may elicit a dimorphic response with both granulomatous and pyogenic features. Byrd Jr R, Payne JL, Roy TM. enables development of a nidus of inflammatory disease at the tip of the lingula or the middle lobe. — Lord Darlington Lady Windermere's Fan, A Play About a Good Woman is a comedy. abscessus is the third most frequently recovered NTM respiratory pathogen in the United States, after M. avium complex and M. kansasii. Lady Windermere Syndrome The onset of several lung-based non-tuberculosis Mycobacterium avium complex infections is known as the Lady Windermere syndrome. Other nontuberculous mycobacteria, including Mycobacterium genavense, M. intracellulare, M. haemophilum, M. simiae, M. xenopi, M. scrofulaceum, M. marinum and M. fortuitum, have also been described as a cause of disseminated infection in HIV-infected patients. In addition, MAC infection of the liver and biliary tree is common in AIDS patients. The RGMs have also been thought to colonize lipoid pneumonia178; however, it is more likely that the pathogenesis of the lung injury pattern caused by the RGMs is similar to that seen in skin and soft tissue cases, in which various combinations of suppurative foci, poorly formed or necrotizing granulomas, scattered multinucleated giant cells, and vacuoles are typical (termed pseudocysts).179 These combined features may mimic lipoid pneumonia and constitute an important clue to the presence of RGM infection. It is named after a character in Oscar Wilde 's 1892 play Lady Windermere's Fan. Ann E. McCullough MD, Kevin O. Leslie MD, in Practical Pulmonary Pathology: A Diagnostic Approach (Third Edition), 2018, NTM infections may be similar to those due to M. tuberculosis, but certain differences have been noted. This is known as Lady Windermere syndrome. 6 Revista Argentina de Diagnóstico por Imágenes Infección pulmonar por micobacterias atípicas: Síndrome de Lady Windermere Gustavo Raichholz, Sebastián Giménez, Hernán Brouver de Koning, Cristian Froullet, José Luis Sañudo. Colonization and pseudo-infection also result from nosocomial reservoirs of NTM, but their detection and diagnosis are equally important clinically as they cause diagnostic confusion and increase healthcare costs. An example is M. chimaera associated with extracorporeal membrane oxygenation (ECMO), with the reservoir being ECMO-associated thermoregulatory devices, but no associated infections have been reported in patients undergoing ECMO (Trudzinski et al., 2016). Environmental exposure is, therefore, the primary determinant of NTM infection in nosocomial settings. 3 . 44, No. Cystic fibrosis. MAC are facultative intracellular organisms that are aerobic, slow growing (10 – 21 days on solid media) acid fast bacilli. Atypical mycobacteriosis due to M. kansasii infection has been reported in rhesus and squirrel monkeys (Valerio et al., 1979; Brammer et al., 1995). Lady Windermere suspects that her husband is having an affair with another woman, Mrs Erlynne. Similar lesions have been recognized in common marmosets associated with M. gordonae infection (Wachtman et al., 2011). Lady Windermere's Fan, A Play About a Good Woman is a four-act comedy by Oscar Wilde, first performed on Saturday, 20 February 1892, at the St James's Theatre in London.. Whether this entity represents an infection, a colonization, a hypersensitivity reaction, or a hybrid condition remains unresolved at this time. Organisms are usually sparse and more difficult to find in the immunocompetent patient. The diagnosis was Lady Windermere syndrome. The distinctive elements of the Lady Windermere syndrome suggest the hypothesis that habitual voluntary suppression of expectoration ("Ladies do not spit.") A similar infection-colonization-hypersensitivity syndrome has been described in workers exposed to metalworking fluid aerosols.173 The clinical, radiologic, and pathologic findings are similar to disease associated with hot tub use and other water sources except that a distinctive rapid-growing NTM species, M. immunogenum, has been recovered almost exclusively. Dhillon SS, Watanakunakorn C. Lady Windermere syndrome: middle lobe bronchiectasis and Mycobacterium avium complex infection due to voluntary cough suppression. The chest roentgenogram of our Fig 1. Once sufficient growth is achieved, the diagnosis of MAC can be made in few hours with the use of DNA probes (see Chapter 174). Writes Dr Samer Alkhuja of Greenwich, Conn, an M avium pulmonary disease presenting as an isolated lingular mass in a woman with no clinically apparent predisposing lung disorder is described as the Lady Windermere syndrome. Lady Windermere syndrome is named after a character in an Oscar Wilde Victorian-era play. Februar 1892 im St. James's Theatre in London statt. A 1- to 2-cm area of blanched, thickened skin was found at the abdominal test site. Other atypical mycobacteria occasionally cause liverdisease, including Mycobacterium kansasii and bacille Calmette-Guérin. The condition often occurs in older white females who habitually repress their cough reflex. The Lady Windermere Syndrome. Infections due to MAC and other common pulmonary NTM pathogens generally manifest as one of five clinicopathologic entities: solitary pulmonary nodule, chronic progressive pulmonary disease, disseminated disease, chronic bronchiolitis with bronchiectasis, and hypersensitivity-like pneumonitis.147,170 Solitary pulmonary nodules generally exhibit granulomas resembling those caused by M. tuberculosis. The antituberculous agents were discontinued after 2 weeks, because the patient remained febrile and a rash had developed. The NTM thrive in hot water especially since temperatures over 84 F (29.4 C) can cause chlorine to lose its ability to kill germs. 3. Patients with Lady Windermere syndrome experience chronic cough, shortness of breath, fatigue and other less specific symptoms. Reich JM, Johnson RE. Disseminated MAC disease is characterized by fever, night sweats and weight loss. Lady Windermere, discovers that her husband may be having an affair with another woman. Focal cylindrical bronchiectasis predominates, and the … Hypersensitivity-like pulmonary disease has been associated with contaminated water in hot tubs (“hot tub lung”) and other environmental sources such as humidifiers and air conditioners.16 Biopsy reveals a miliary bronchiolocentric and interstitial granulomatous pattern, similar to that produced by hypersensitivity pneumonitis (Fig. Hi - I was diagnosed with MAI (mycobacterium avium intracellulare) in 2000 and my culture was positive for aspergillus niger. Other nontuberculous mycobacteria, including Mycobacterium genavense, M. intracellulare, M. haemophilum, M. simiae, M. xenopi, M. scrofulaceum, M. marinum and M. fortuitum, have also been described as a cause of disseminated infection in HIV-infected patients.
