Combined nitrofurantoin toxicity to liver and lung.

Nitrofurantoin is an antibiotic commonly used for prophylaxis and treatment of urinary tract infections. Pulmonary and hepatic toxicity are rare side effects of this agent. The simultaneous occurrence of pulmonary fibrosis and chronic active hepatitis in a patient undergoing long-term nitrofurantoin therapy is reported. The presence of pulmonary toxicity was evidenced by infiltrates on chest radiographs and impaired diffusion capacity during pulmonary function tests. Prolonged elevation of liver enzyme concentrations together with the presence of increased antibody titers (anti-smooth muscle antibody, antinuclear antibody) was suggestive of chronic hepatitis, a diagnosis corroborated by liver biopsy findings. After discontinuation of nitrofurantoin therapy, the patient had a full recovery. The infiltrates initially found on chest radiographs disappeared, and laboratory parameters normalized without the need for corticosteroid therapy.

[The diagnostic assessment of enlarged lymph nodes by the qualitative and semiquantitative evaluation of lymph node perfusion with color-coded duplex sonography].

Perfusion of enlarged lymph nodes by colour-coded sonography was studied prospectively in 105 benign and 115 malignant lymph nodes. The diagnosis was confirmed histologically in 158 and clinically in 62. Spectral analysis in the benign lymph nodes provided normal values for pulsatility and resistance indices. A pulsatility index greater than = 1.8, or a resistance greater than = 0.9 indicate lymph node metastases with positive prediction of 93% and specificity of 97%. In addition, subjective, semiquantitative classification of lymph node perfusion in relation to the surrounding fat or connective tissue improves the diagnosis of lymph node metastases and of malignant lymphomas.

[Various factors influencing the local anesthetic effect of articaine].

In a field study, the reduction in the anaesthetic effectiveness of Articain was investigated in relation to various influencing parameters. Both in the ZMK-Klinik (Dental Hospital) of Würzburg as well an in various independent practices, the local anaesthetic Articain was given to over 2000 patients in the course of dental treatment. With 12.1% of all test-subjects, inspite of the initial positive effectiveness upon application of the nerve-blocking anaesthetic, touch sensitivity and/or painfulness was established in the area concerned. Statistical evaluations of the recorded data of the test-subjects investigated showed a significantly higher quota of anaesthetic failure in the case of heavy cigarette consumption, chronic exposure to inhaled toxins as well as in the case of the intake of medicines of certain pharmaceutical types. Apart from that, a connection was also established between reduction in the effectiveness of the local anaesthetic and various treatments as well as the way in which the local anaesthetic was applied and the site of injection. Possible causes will be presented and discussed in relation to information from the literature on the subject.

Kininase I and II activities in serum of patients with lung diseases.

In serum of 530 patients with various lung diseases and in 70 healthy control subjects, kininase I (E.C. 3.4.17.3) and kininase II (E.C. 3.4.15.1) were measured spectrophotometrically using hippuryl-L-arginine for estimation of kininase Ia (KIa), hippuryl-L-lysine for kininase Ib (KIb) and hippuryl-L-histidyl-L-leucine for kininase II (KII). KIa and KIb were significantly elevated (p less than 0.02) in lung cancer and sarcoidosis, compared to tuberculosis and healthy controls. There was an increase (p less than 0.05) in lung cancer in relation to sarcoidosis, chronic obstructive bronchitis, tuberculosis, pulmonary fibrosis and healthy control subjects. KII was significantly elevated in sarcoidosis (p less than 0.0001). According to the histological types of lung cancer, no differences of KIa, KIb and KII have been found. The ratio KIa/KIb X KII was 2.3 in lung cancer and 6.7 in the group with sarcoidosis. These results show that the determination of kininases can be used for diagnosis of lung diseases.
