[Difficulties in diagnosing pulmonary visceral forms of rheumatoid arthritis in tuberculous hospital]. / Trudnosti diagnostiki legochno-vistseral'nykh form revmatoidnogo artrita v klinike tuberkuleza.

The articulovisceral form of rheumatoid arthritis is severe, which creates difficulties in its diagnosis as it is characterized by polymorphism and atypical features. This type concurrent with pulmonary manifestations should be differentiated from inflammatory lung diseases, including tuberculosis.

[Variants of development of complete atrioventricular block. Prognosis in disorders of intraventricular conduction]. / Varianty razvitiia polnoi atrioventrikuliarnoi blockady. Prognoz pri narusheniiakh vnutrizheludochkovogo provedeniia.

In a group of patients with complete atrioventricular block admitted for implantation of a cardiac stimulant, 15 out of 74 patients (20.3%) had normal intraventricular conduction before the block, while 59 (79.7%) had disorders of intraventricular conduction. A combination of right bundle-branch block with block of the anterior limb of the left branch was the most frequent occurrence (37.8%). Comparison of the QRS complexes in maintained atrioventricular conduction with those in complete antrioventricular block showed that among patients with disorders of intraventricular conduction complete atrioventricular block was of a proximal character in 45.5% and of a distal character in 54.5% of cases. There was a high risk of development of complete atrioventricular block in patients with right bundle-branch block combined with block of the anterior limb of the left branch; it was found to be 41.2% at an average follow-up period of 23 months.
