Conservative nonsurgical treatment of early detected tubal pregnancies with intra-amniotic methotrexate.

Four cases of early detected tubal pregnancies were managed conservatively by aspiration and administration of 20 mg methotrexate into the amniotic sac during laparoscopy. All three women for whom hysterosalpingograms are available had patent tubes on the side of the former ectopic pregnancy six months after treatment. Spontaneous menstruation occurred within six weeks after methotrexate application in all cases.

Electrical potential difference across the mid-term human placenta.

Electrical potential difference across the mid-term human placenta was recorded during hysterotomy. The average value registered was 2.7 mV (S.E. of mean=0.4 mV, n=7), fetus negative. From this value and the concentrations of Na, K, Ca, Cl and inorganic phosphate in maternal and fetal plasma the possible mechanisms of net transport from mother to fetus are inferred. It is concluded that of the above ions only the transport of Na is compatible with simple diffusion.

[Therapy of chronic hepatitis (author's transl)].

Therapy of chronic hepatitis as practized today is discussed, including general therapeutic procedures, the so-called "liver-protective substances", and drug therapy of chronic aggressive hepatitis and of liver cirrhosis. A causal treatment of chronic hepatitis is unknown; prognosis however can be improved by treatment with glucocorticoids as demonstrated by controlled clinical trials. A combination with azathioprin does have similarly good results with a decreased frequency of the unwanted side effects of the 2 drugs. The effects of other immunosuppressive drugs and of D-penicillamin cannot yet be evaluated sufficiently at present.

[Diagnostic value of cytological investigations in metastatic tumours of the liver: comparison of laparoscopy, histology, and cytology (author's transl)].

Fine needle aspiration biopsy is generally a harmless method if contraindications are considered and provides sufficient tissue for cytological evaluation. The diagnostic value is very high: in 27 cases of metastatic tumours of the liver diagnosed by laparoscopy the diagnosis was confirmed in 26 cases and revised in one case. In a control group of 200 patients with various diffuse liver diseases or morphologically normal findings no false positive results were found. In no case were post-biopsy haemorrhage or other complications observed. Needle biopsy and cytological evaluation should be used with an increased frequency when a malignant tumour of the liver is suspected clinically. After primary localization of suspicious areas by ultrasound or scanning the pick-up rate is high. Laparoscopy with precisely aimed fine needle biopsy is the method for verifying the diagnosis in cases with cytologically negative results which is up to 100% accurate.

[Differential diagnosis of acute viral hepatitis and liver cirrhosis with severe activity (author's transl)].

Results of biochemical tests in 61 patients with acute viral hepatitis resp. 63 patients with subacute hepatitis were compared with laboratory findings of 27 patients with liver cirrhosis in the stage of severe activity of the disease. In acute and subacute viral hepatitis was the activity of GPT and CHE significantly higher than in active cirrhosis of the liver. In contrast to these findings was the activity of GLDH and the blood level of bilirubin in both groups of patients similar and for the differential diagnosis of no importance. Low albumin, high gammaglobulin and significant increase of IgG and IgA fractions of immunglobulins in serum are additionally to the results of the activity of some serum enzymes for the diagnosis of active liver cirrhosis in comparison to acute and subacute viral hepatitis of greatest value.

[Comparison of laparoscopic and scintigraphic findings in chronic hep-titis, liver cirrhosis and liver tumours (author's transl)].

Results of laparoscopy and scintigraphy were compared and contrasted with ultimate clinical diagnosis in 94 patients with chronic hepatitis or liver cirrhosis and 38 with liver tumours. The findings agreed in 77 cases of chronic hepatitis and cirrhosis and 33 of liver tumour. In the remainder either laparoscopy or scintigraphy gave the wrong results. In one case each of cirrhosis and liver metluded that (1) laparoscopy and scintigraphy are methods complementing but not replacing other clinical tests; (2) if diffuse liver disease is suspected clinically the diagnosis can essentially be done only by laparoscopy and selective biopsy or blind liver biopsy but not scintigraphy; (o) if a circumscribed condition is suspected, scintigraphy is among the most important screening tests, but cannot replace laparoscopy, biopsy or angiography for confirming the diagnosis; (4) liver scan is an important method, of little stress to the patient, in following the progress of chronic hepatitis and liver cirrhosis, additional to clinical examination, enzyme tests, laparoscopy and histology.
