Obstetrician-gynecologists reviewed patient records of women delivering during January 1986-December 1992 to determine the maternal mortality rate and trends and the causes of maternal deaths in the maternity ward at the National University of Singapore. There were 26,173 deliveries and 9 maternal deaths (a maternal mortality rate of 22.9/100,000). The causes of maternal deaths were pulmonary embolism (underlying condition, systemic lupus erythematosus [SLE]), hemorrhage from multiple sites (thrombotic thrombocytopenia), acute exacerbation of SLE with interstitial pneumonitis, pulmonary fibrosis (systemic sclerosis), fulminant hepatitis (prior hepatitis and liver disease), and cerebral embolism (rheumatic heart disease with mitral valve replacement). There were also three incidental maternal deaths bringing the maternal mortality rate up to 34.4/1000. The incidental causes of death included septicemia from perforated peptic ulcer (uncontrolled thyrotoxicosis), multiple metastases from lung cancer, and suicide (family dispute over adoption of newborn). A cesarean section preceded 4 (44%) of the 9 maternal deaths. Two of these deaths were incidental maternal deaths. Cesarean section was related to two of the remaining six (33%) deaths. These findings show that traditional direct causes of maternal death (hemorrhage, sepsis, embolism, or hypertension) were not responsible for the maternal deaths at this tertiary facility. Instead, the women tended to have medical conditions that placed them at high risk of death regardless of pregnancy status.

A case of hepatocellular carcinoma (HCC), which developed during chemotherapy for chronic myelogenous leukemia (CML), is presented. A 55-year-old Japanese man, who had received an alkylating agent for 16 years, was diagnosed as having HCC with clinically evident splenic metastases. The patient died of the HCC rupture three months after diagnosis. The autopsy revealed the HCC to have developed from the non-cirrhotic liver. In the present case, DNA damage due to the long-term chemotherapy with the alkylating agent for CML may have endowed the HCC induced by post-transfusion hepatitis and alcohol abuse with an aggressive proliferative potential. This is the first report on HCC in association with CML.

Thirty-one patients with hepatic metastases from colorectal carcinoma were treated with carboplatin (CBDCA), 55 mg/m2, given in a 4-hour intra-arterial infusion daily for 5 days, and 5-fluorouracil, 900 mg/m2, given in a 20-hour intra-arterial infusion daily for 5 days. Cycles were administered every 5 weeks. Objective responses were observed in 16 (51.6%) patients (5 complete and 11 partial responses). Another 13 patients maintained stable disease, and 2 patients rapidly progressed. The overall median survival was 23.5 months. The 16 patients with objective response had a median survival of 26.5 months. In this series, no evidence of biliary sclerosis, cholecystitis, chemical hepatitis, or myelosuppression was observed. Complications of drug delivery system were observed in 14 (45.16%) patients. In conclusion, intra-arterial hepatic chemotherapy with CBDCA-5FU was associated with a modest benefit, expressed in good quality responses and extended survival of approximately 2 years in about half of the treated patients.

Quantitative phase-contrast magnetic resonance (MR) angiography of the portal vein was prospectively evaluated in 79 fasting patients and 23 healthy volunteers. Images were obtained during a 12-second breath-hold acquisition in the coronal (n = 102) and axial (n = 11) planes. Pathologic correlation was available in 55 of 79 patients and included findings of cholangiocarcinoma, cirrhosis, hepatocellular carcinoma, hepatitis, and metastatic disease. Forty-one patients had correlative Doppler ultrasound (US) findings. MR and US findings correlated as to flow direction in all cases. In nine patients, Doppler US velocity measurements were available and closely correlated with MR findings. A comparison of axial and coronal portal venous phase-contrast measurements in 11 patients revealed no substantial difference with regard to the plane used. Quantitative phase-contrast MR angiography is a simple and rapid technique for the assessment of portal venous patency, flow direction, and flow velocity and, combined with high-resolution conventional MR imaging, may obviate the current use of both computed tomographic and US examinations.

The results of treating 12 consecutive patients with unresectable colorectal hepatic metastases with a hepatic arterial infusion of high-dose Adriamycin, 100-120 mg/m2, using hepatic venous isolation (HVI) and charcoal hemoperfusion (CHP) are reported herein. Adriamycin was administered over 5-15 min under extracorporeal drug elimination by HVI-CHP. HVI was percutaneously accomplished by either the double-balloon technique using a Fogarty occlusion catheter (8/22F) or a balloon-tipped catheter (16F). During the infusion, isolated hepatic venous blood was filtered by CHP and pumped into the left axillary vein. There were no lethal complications, and good hemodynamic tolerance to HVI-CHP was confirmed. Tumor liquefaction accompanied by a sharp decrease in serum carcinoembryonic antigen levels by more than 50% of pretreatment levels was observed in 6 of the 12 patients 1 month after treatment. Apart from chemical hepatitis, which developed in 11 (92%) of the patients, the Adriamycin toxicities were well controlled following the development of nausea and vomiting in 2 patients (17%), leukopenia < 2,000/mm3 in 3 (25%), and gastric ulcer in 1 (8%). These results indicate that this method is a safe and useful procedure for otherwise hazardous high-dose intra-arterial chemotherapy in patients with unresectable hepatic tumors.

Oral metastases from hepatocellular carcinomas are rare. Case 1 was a 66-year-old male without previous history of liver disease who presented with metastasis to the gingival jaw mucosae on the lingual side. Case 2 was a 71-year-old male, with a previous history of diabetes, hepatitis, and cirrhosis who presented with metastasis to the right palatine tonsil. Oral metastases were the first manifestation of the hepatocellular carcinoma in both cases. A review of the literature disclosed 20 cases of hepatocellular carcinoma metastasizing to the oral cavity, 7 affecting the gingival mucosae and none of them affecting the palatine tonsil.

Persistent human immunodeficiency virus (HIV) infection induces an immuno-suppressive state and therefore malignant tumors are a very common complication. Hepatocellular carcinoma is very rare, however, because it is associated with chronic liver disease by the persistent infection of hepatitis B or C virus (HBV or HCV). We reported a case of HCC with HIV infection who had no evidence of HBV or HCV infection, and that had a rapid growth and active pulmonary metastases. Pathological findings of the resected liver showed moderately differentiated HCC and no chronic liver disease. Despite efforts to find potential HBV integration in tumor and non-tumor tissue, none was observed. To our knowledge, this is the first report of HCC in HIV-infected patient with no evidence of hepatitis virus infection.

Drug-induced cholestasis may be due to impairment of hepatocellular bile secretion (pure cholestasis or cholestatic hepatitis), obstruction of ductules (cholangiolitis) or interlobular ducts (cholangitis), or extrahepatic obstruction (sclerosing cholangitis). Mechanisms of hepatocellular cholestasis are multiple and include inhibition of various transport systems, cytoskeleton poisoning, disturbed intracellular calcium homeostasis and increased permeability with regurgitation of bile constituents into plasma. Pure hepatocellular cholestasis is mostly observed with sex steroid hormones and anabolic steroids. Ductular or ductal cholestasis (drug-induced cholangiopathy) may be acute and self-limited, or prolonged with ductopenia, occasionally leading to biliary cirrhosis. An immune mechanism has been proposed. Sclerosing cholangitis with strictures near the confluent of hepatic ducts is observed after intraarterial administration of floxuridine for chemotherapy of hepatic metastases. Some drugs may induce the formation of cholesterol gallstones, or precipitate in bile and form biliary sludge or stones in the gallbladder or common bile duct.

Chronic inflammatory states frequently lead to the increased production of nitric oxide (NO) via inducible NO synthase (NOS-2). In addition, NO may produce mutagenesis through several mechanisms such as DNA oxidation, DNA deamination, and the formation of N-nitroso compounds. As there is a strong association between human hepatitis C virus (HCV) infection and the development of hepatocellular carcinoma (HCC), we were interested in whether human HCV hepatitis leads to induction of NOS-2 and if the mutation repair system of p53/p21 was upregulated. Reverse transcriptase-polymerase chain reaction (RT-PCR) for human NOS-2 message was performed on RNA samples from both liver biopsies and whole liver from HCV-positive and control patients (normal liver from hepatic resections for metastases). Immunohistochemistry (IHC) for p53 and Western blot analysis for p21 were also performed on the whole liver samples. From the liver biopsies, 60% of HCV-positive patients expressed NOS-2 by RT-PCR. Looking at the whole liver samples, 100% of the HCV-positive patients expressed NOS-2 vs 12.5% in the normal samples. p53 was not detected in either group but there was upregulation of p21 over baseline expression in a number of the HCV-positive patients. Human HCV hepatitis leads to consistent upregulation of hepatic NOS-2 message, but message is not predictably present in "normal" human liver. There is also induction of p21 in some patients with HCV hepatitis. Chronic expression of NO in HCV hepatitis may play a role in DNA mutagenesis and the development of HCC.

Little is known about the coincidence of hepatitis C virus infection (HCV) and non-Hodgkin's lymphoma, although there is an increased incidence of chronic HCV infection with cryoglobulinemia type II and, interestingly, low-grade non-Hodgkin's lymphoma (NHL) in a few patients. We therefore report on a 74-year-old white male with known chronic hepatitis C virus infection who was admitted to the clinic due to weight loss and pain in the right upper quadrant. Ultrasound examination was performed for suspected hepatocellular carcinoma since a lesion in the left lobe of the liver was seen. X-ray of the lungs showed a few scattered lesions, suggestive of metastases. The ultrasound-guided fine-needle puncture revealed a high-grade malignant B-cell NHL While alpha-fetoprotein was normal, both cryoglobulin type II and the polymerase chain reaction (PCR) for HCV were positive. After six cycles of chemotherapy consisting of CHOP, the patient showed complete remission over three years. Ultimately, he died due to a sudden myeloic blast crisis. In summary, we discuss the possible etiopathologic role of the hepatitis viruses in the occurrence of non-Hodgkin's lymphoma. As we and others showed that HCV infects peripheral mononuclear blood cells (PBML), the infected PBML not only may be a source for reinfection after orthotopic liver transplantation, but also could be the cause for transformation and monoclonal propagation of lymphomatous tissue.
