[Pulmonary tuberculosis presenting multiple nodular shadows in 4 patients].

Four cases of multiple nodular pulmonary tuberculosis simulating metastatic lung cancer were reported. These patients were asymptomatic, found by chance during physical checkups, and had no clinical findings indicative of inflammatory reactions. The nodules ranged from 15 to 50 in number, were spherical in shape, and 3-10 mm in diameter with sharp margins.

[Shortening of hospitalization period for patients with pulmonary tuberculosis].

The development of specific chemotherapeutic agents revolutionally improved the prognosis of tuberculosis and markedly shortened the duration of the treatment. Evidence of successful treatment with short-course regimens for pulmonary tuberculosis has been accumulated. But, the duration of hospitalization tends to be determined empirically and varys among hospitals and clinicians.
