To estimate whether WHO\'s End TB Strategy targets can be achieved by analysing the incidence trend of pulmonary tuberculosis in Shanghai during 1992-2016.
The age-adjusted annual incidence of tuberculosis (TB) was calculated based on data from the national TB registration system. Linear regression was applied to analyse the trend of the epidemic, together with the statistical indicator of annual percent change (APC).
The overall age-standardised rate decreased from 34.8/100 000 in 1992 to 21.2/100 000 in 2016, or by 2.15% (t = -13.258, P < 0.05) annually. After rapidly declining between 1999 and 2003 (-5.4% p.a.), the epidemic remained at a stable level with a lower annual declining rate (-1.1% p.a). In 2035, the estimated incidence will be 17.2/100 000 based on the APC in 2004-2016. There were two peaks in average incidence of the total population, 30.9/100 000 in the 20-24 age group and 66.4/100 000 in the 70-74 age group. Overall, the ratio of new to retreated cases continually rose and eventually reached 8.36:1 in 2016. The constituent ratio of smear-positive cases ranged from 35.9% to 47.8% without rising or decreasing trend (P = 0.065).
The epidemic of TB in Shanghai has steadily declined during last two decades. A new strategy should be developed to rapidly reduce the incidence rate to achieve the WHO Goals in 2035.

BACKGROUND: Bronchial mould infection or plastic bronchitis is a rare condition, encountered at any age, but with a predilection for childhood. The clinical diagnosis is made easy by the demonstration of solid, branched expectorations. However, the aetiology is not easy to determine and investigation does not often lead to a pathological diagnosis.
METHODS: We report the case of a 24 year-old patient, with a history of pulmonary tuberculosis in January 2016, who had had chronic, persistent, solid and branched expectorations since January 2015. Fibreoptic bronchoscopy revealed thick white secretions plugging the bronchi. Pathological examination of the bronchial plugs showed fibrous tissue infiltrated with predominantly lymphoplasmocytic and histiocytic inflammatory cells. Investigations carried out on the pleura did not establish the aetiological diagnosis. The diagnosis of bronchial mould disease of tuberculous origin complicated by pleurisy was established. Corticosteroid therapy led to a complete regression of the moulds within six weeks.
CONCLUSIONS: The presence of solid and branched sputum should suggest fungal bronchitis and is an indication for bronchoscopy for diagnostic and therapeutic purposes. Early management is important to avoid complications.

OBJECTIVE: To describe the residual broncho-pulmonary lesions and evaluate the role of CT scanning at the end of treatment of pulmonary tuberculosis.
METHODS: Analysis of the initial and end of treatment CT scans of 56 patients with pulmonary tuberculosis according to a reading grid including parenchymatous and airways lesions. The CT data at the end of treatment were analysed in relation to the clinical and microbiological data, and the original CT scan.
RESULTS: Active lesions (thick walled cavities and/or centrilobular micronodules) persisted in 24 patients (43%) after a mean treatment period of 7 months. The persistence of these signs of activity was correlated with the initial presence of a cavitary syndrome (p=0.027), with predominant sub-segmentary bronchial involvement, with extensive micronodular spread (p=0.024) and with bronchiectasis (p=0.04). These residual lesions were not associated with an increased risk of relapse.
CONCLUSIONS: The persistence of signs of activity on the CT scan at the end of treatment of tuberculosis do not necessarily correspond to an absence of cure but to a radiological delay. This imaging is nevertheless useful to make an assessment of any subsequent changes in the bronchial tree and to estimate the risk of later complications.

Despite the availability of potent drugs and the availability of vaccine, tuberculosis remains until today one of the most worrying infectious diseases because of both its morbidity and mortality. This serious health problem is further complicated by the emergence of multidrug-resistant (MDR) or extensively drug-resistant strains (XDR). The number of MDR and XDR strains has continued to increase in recent years. Therefore, it is necessary to determine the risk factors leading to the emergence of MDR-TB strains to improve its overall management. Most studies indicate that the irregular previous treatment of tuberculosis with poor adherence is the main risk factor found. Other risk factors such as digestive issues, age, sex, and immunosuppression have been reported by several studies. In Tunisia, MDR-TB prevalence remains low with 0.8% among new cases and 12% among the restatements but control of this disease is necessary and remains essentially preventive. It is based on real preventive strategies planned according to local and updated regional data.

OBJECTIVE: Eight of 17 districts of Shanghai have offered transportation and living allowances subsidies to patients with tuberculosis (TB) among the migrant population. The study aimed to assess the impact of the subsidising initiative on the treatment success rate (TSR) and identify the social determinants of treatment outcomes.
METHODS: The participants included 7072 residents and 5703 migrants who were registered in the TB Information Management System with smear-positive pulmonary TB from January 2006 to December 2010. The Cochran-Armitage test was employed to test the trends of TSR and logistic regressions to identify the factors associated with treatment outcome.
RESULTS: Without subsidies, migrant TB cases had lower odds of successful treatment [OR = 0.20 (95% CI 0.18-0.23)] than resident cases. Subsidisation was associated with a 65% increased odds ratio of success [1.65 (1.40-1.95)] among migrant cases. The TSR has stabilised at 87% for both permanent residents and temporary migrants since 2009. Living in districts with a population density ≥20,000/km(2) was associated with a low odds ratio [0.42 (0.26-0.68)] among resident cases, whereas among migrant cases those living in districts out of central downtown had a higher odds ratio of treatment success [peripheral downtown: 1.73 (1.36-2.20), suburban: 1.69 (1.16-2.46)]. The TB cases in districts with 2.0-2.9 TB specialists/100 cases had a higher odds ratio [2.99 (1.91-4.69)] of successful treatment than cases from districts with fewer specialists.
CONCLUSIONS: Besides free medical services, transport and living allowance subsidies to migrant patients with TB improved the treatment outcome significantly.

BACKGROUND: Immunodepression induced by the human immunodeficiency virus (HIV) modifies the clinical, radiological and microbiological manifestations of pulmonary tuberculosis; leading to similarities between pulmonary tuberculosis and acute community-acquired bacterial pneumonia. A consequence is the high proportion of discordant pre- and post-mortem diagnoses of pneumonia. The aim of our study was to contribute to the improvement in the diagnosis of acute bacterial pneumonia in HIV positive patients in areas where tuberculosis is endemic.
METHODS: This retrospective study in HIV positive patients has compared 94 cases of positive smear cases pulmonary tuberculosis and 78 cases of acute community-acquired bacterial pneumonia.
RESULTS: Using logistic regression, the following features were positively associated with bacterial pneumonia: the sudden onset of signs (OR=8.48 [CI 95% 2.50-28.74]), a delay in the evolution of symptoms of less than 15 days (OR=3.70 [CI 95% 1.11-12.35]), chest pain (OR=2.81 [CI 95% 1.10-7.18]), radiological alveolar shadowing (OR=12.98 [CI 95% 4.66-36.12) and high leukocytosis (OR=3.52 [CI 95% 1.19-10.44]). These five variables allowed us to establish a diagnostic score for bacterial pneumonia ranging from 0 to 5. The area under the ROC curve was 0.886 [CI 95% 0.84-0.94, P<0.001]). Its specificity was >96.8% for a score of greater than or equal to 4.
CONCLUSIONS: The diagnostic score for acute community-acquired pneumonia may improve the management of bacterial pneumonia in areas where tuberculosis is endemic.

BACKGROUND: We studied the incidence of tuberculosis in the health district of Saint-Louis, Senegal over a period of 4years (2008-2011). One thousand three hundred and eighty-six cases were identified, producing an annual standardized incidence ratio of 129 cases per 100,000 inhabitants.
RESULTS: Men in the 15-24-year old age group were more likely to be affected, and diagnosis was more common in the second half of the year. Treatment compliance was excellent (96%), and the cure rate of patients with a TB-positive microscopic examination was 95%. The overall treatment failure rate was 1% and the 6-month morality was 2%. Seropositivity, measured in volunteer patients (48%) was 3%.
CONCLUSIONS: A spatial and temporal map of tuberculosis in the city of Saint-Louis, Senegal has been established. A cluster appears to be very likely in Guet Ndar, a particularly dense population zone in a fishing area. There is also a possible secondary cluster at Pikine.
