Recent epidemiological trends in extrapulmonary TB in Galicia, Spain.

OBJECTIVE: To describe the epidemiological trends and characteristics of extrapulmonary tuberculosis (EPTB) in Galicia, Spain, from 2000 to 2019.METHODS: This was a retrospective cohort study based on data from the Galician TB information system.RESULTS: Of the total number of TB cases (n = 15,871), 5,428 (34.2%) had EPTB. The absolute number of cases and incidence of EPTB decreased dramatically (from 480 cases and 17.8 cases/100,000 in 2000, to 172 and 6.4 cases/100,000 in 2019, respectively), with a mean annual decrease of respectively 64% and 4.7% for absolute cases and incidence rates. The risk for EPTB was higher in men than in women (RR 3.86, 95% CI 3.66-4.07). The most frequent age group was 15-44 years (2,234 patients, 41.2%); overall reductions per age group were 82% (0-14 years), 75% (15-44 years), 44% (45-64 years) and 63% (≥65 years), with statistically significant differences. The most frequently locations were the pleura (1,916 cases; 35.3%) and the lymph nodes (1,504; 27.7%).CONCLUSION: The incidence of EPTB in Galicia has decreased significantly in the last 20 years. The epidemiological characteristics have not changed, except for the number of patients with risk factors. This improvement of EPTB epidemiological trends coincides with the implementation of the programme for the prevention and control of TB, which suggests that it has been very effective in the control of the EPTB.

[The epidemiology of COPD and asthma exacerbations in a general hospital]. / Características epidemiológicas de las exacerbaciones por EPOC y asma en un hospital general.

This retrospective study identified the clinical and epidemiological characteristics of patients coming to the emergency room of our hospital with exacerbated asthma or chronic obstructive pulmonary disease (COPD) in 1993 and 1994. We followed a previously established protocol to review the case histories of patients from both years. The 1,592 exacerbations we identified in 1,209 asthmatics accounted for 0.9% of all emergency visits, with a mean of 2.2 1.6 (0-9) visits daily. The 2,106 exacerbations of COPD in 1,208 patients accounted for 1.2% of all emergencies, with a mean 2.9 (1-12) visits per day. The mean age was 51.2 (14-93) years for asthmatics and 70.3 (29-96) years for COPD patients. Of asthmatics, 69.8% were women and 30.1% were men, whereas 91.4% of COPD patients were men. The readmission rate was 3.4% for asthmatics and 4.8% for COPD patients. The hospitalization rate was 26.7% for asthmatics and 49.4% for COPD exacerbation patients. The hospital saw 22.6% of asthma exacerbations between midnight and 8 a.m. and 41.6% of COPD exacerbations during the same time frame. For both diseases, more emergencies occurred in winter. Correlation between asthma and COPD and declared influenza cases in the community were r = 0.63 (p < 0.001) for asthma and r = 0.83 (p < 0.0001) for COPD. Our findings underline the considerable emergency care burden generated by exacerbations of obstructive airway diseases and suggest that community acquired respiratory infections are usually the underlying cause.

[Pseudotumoral allergic bronchopulmonary aspergillosis]. / Aspergilosis broncopulmonar alérgica seudotumoral.

Allergic bronchopulmonary aspergillosis (ABPA) develops as the result of a hypersensitivity reaction to fungi of the genus Aspergillus. Clinical and radiological presentation can be atypical, requiring a high degree of suspicion on the part of the physician who treats such patients. We report the cases of two patients with APBA in whom the form of presentation--with few asthma symptoms, images showing lobar atelectasia and hilar adenopathy--led to an initial suspicion of lung cancer.
