BACKGROUND: Pleural tuberculosis in young people is considered to be due to primoinfection. We analyze the direct relationship between trends on pleural and general tuberculosis in our county. METHODS: We performed a retrospective study regarding pleural and general tuberculosis annual rates in Bajo Deba County from January 1992 to December 2012. Data before 1995 were not reliable in regard to general tuberculosis and underestimation was expected. All pleural cases were reliably recorded. Based on the relationship and trends observed in the 1995-2012 period, we try to find the true general tuberculosis annual rate based on the pleural incidence in people aged under 40 years following the Poisson models. RESULTS: 169 of pleural tuberculosis cases and 773 cases of general tuberculosis were recorded respectively. The descending trend regarding annual incidence of general and pleural tuberculosis during the period 1995-2012 was statistically significant. The increment on general tuberculosis in terms of annual incidence rate was 1.29 unit per each unit incremented on pleural tuberculosis annual incidence rate in people aged under 40 years. Following this model we estimated that the mean number of cases of general tuberculosis before 1995 was 23 cases more than those recorded. CONCLUSION: We check the potential utility of pleural tuberculosis rate in young people as a good indicator of general tuberculosis rate.

Because of its unpredictable behavior, renal cell carcinoma is one of the most controversial neoplasms. On the one hand, patients frequently show metastases at diagnosis because of its slight manifestations, while on the other, the neoplasm can remain stable after nephrectomy and can then metastasize many years later. When this happens, the metastases usually involve more than 2 organs. The most frequent sites of metastases are the lung and lymph nodes, followed by the bones and liver, while duodenal involvement is rare. Indeed, intestinal metastases are found in only 2% of autopsies and of these, renal cell carcinoma metastases account for 7.1%. We present a case of a solitary late recurrence presenting as upper gastrointestinal bleeding 19 years after nephrectomy for clear cell renal carcinoma.
