Id: 17549 Author: Boggild, Andrea K; Correia, Jason D; Keystone, Jay S; Kain, Keven C Title: Leprosy in Toronto: an analysis of 184 imported cases ..- Source: s.l; s.n; Jan. 2004. 5 p. tab. Abstract: BACKGROUND: Leprosy is a rare but serious mycobacterial infection. Immigration from areas where the disease is endemic has resulted in the importation of leprosy into countries where it is not endemic and where physicians and health care workers have little or no experience in diagnosis and therapy. In this study we characterized leprosy patients seen in a tropical disease unit that manages most of the reported leprosy cases in Canada. METHODS: We reviewed the clinical records of all 184 leprosy patients who were referred to the Tropical Disease Unit at Toronto General Hospital between 1979 and 2002 and abstracted demographic and clinical information. RESULTS: Patients were more likely to be male (122 or 66.3%) and of Indian (44 or 23.9%), Filipino (49 or 26.6%) or Vietnamese (37 or 20.1%) origin. Patients experienced symptoms for a mean of 4.8 years before referral to the Tropical Disease Unit. Most had no family history of leprosy (152/172 or 88.4%). Most patients presented with either borderline tuberculoid (80 or 43.5%) or borderline lepromatous (37 or 20.1%) disease. On average, patients presented with 5.8 skin lesions. Upper- and lower-extremity nerve dysfunction was common at presentation, with up to one-third of patients demonstrating either sensory or motor loss. A significantly greater lag time to presentation was observed in patients who emigrated from low-prevalence regions (p < 0.001). INTERPRETATION: Leprosy is a chronic infectious disease that is associated with serious morbidity if left untreated. Leprosy is uncommon in developed countries, but it is important for physicians to have a high index of suspicion when a foreign-born patient presents with chronic dermatitis and peripheral nerve involvement.

T Title: Valeur prédictive des motifs de consultation pour le diagnostic de lèpre à Bamako (Mali) Predictive value of medical reasons in the diagnosis of leprosy in Bamako (Mali)- Source: s.l; s.n; 2002. 3 p. tab. Abstract: INTRODUCTION: One of the weak points in the strategy for eliminating leprosy is the poor quality of screening. To overcome this, the World Health Organization (WHO) encourages endemic countries to run campaigns for the elimination of leprosy by circulating educational messages and mobilizing the medical community for early screening of cases. The aim of our study was to identify the motives for consultation with high predictive value for the diagnosis of leprosy and to determine the late diagnosis factors and hence assist the staff on site to improve the results of their leprosy elimination campaigns. PATIENTS AND METHODS: The study consisted, during the second trimester of 1999, in interviewing all the patients consulting for the first time the Marchoux Institute or the units screening for leprosy in the Bamako area. The interview recorded the motives for consultation, the delay before consulting and the reasons for late consulting. To assess their positive predictive value, the motives for consultation were related to the diagnosis retained (leprosy or not). RESULTS: One thousand one hundred and seventy seven patients were interviewed. The motive for consulting, "suspected leprosy", scored the highest positive predictive value (PPV) (80 p. 100): 12 cases of leprosy were diagnosed by 15 consultants having suspected leprosy. Neurological problems were the second motive for consultation (PPV=61.9 p. 100). The most frequent motive for consultation was spots or "macules" (20 p. 100 of consultations), but only provided a positive predictive value of 19 p. 100. Prior consultations and non-specialized treatments were identified as factors of delay in diagnosing leprosy (P<0.001). CONCLUSIONS: Diagnosis of leprosy cannot be based on the motives for dermatological consultation alone. The macules are the most apparent signs, but of low predictive value. Nevertheless, they are an early but non-specific sign of leprosy and are often neglected by the patient. Other than macules, attention must be paid to the neurological signs (dysesthesia, motor disorders) when screening for leprosy. These signs may appear early on, or be observed at a late stage in the progression of the disease. (AU).
