We report a patient with hepatocellular carcinoma (HCC) with portal vein thrombosis in the 1st branch who was treated by transcatheter arterial embolization (TAE) and survived more than 3 years. A 58-year old male was diagnosed as having unresectable massive type HCC in the area of S8 with portal vein thrombosis from the P8 branch to the right portal branch. He was treated by TAE via the anterior branch of right hepatic artery. One week later, localized hepatic infarction in the anterior segment was recognized. Five months later, the portal vein thrombosis had disappeared and become necrotic. After 3 years and 4 months, he died of a relapse of a gastric varix, but with no portal thrombosis and a well controlled intra-hepatic recurrence that was treated by repeated TAE. This case suggests that TAE might be effective for cases of HCC with portal vein thrombosis in the 1st branch, if the liver function and portal flow are suitable.

In order to detect a hematogenous spread of tumor cells in patients with hepatocellular carcinoma, reverse transcription-polymerase chain reaction assay has been used. In this study, we quantified alpha-fetoprotein (AFP) messenger RNA by real-time PCR approach using LightCyclertrade mark technique. AFP messenger RNA in the blood from 23 hepatocellular carcinoma patients undergoing hepatic resection, 31 healthy volunteers, 10 patients with liver cirrhosis and 5 patients underwent hepatectomy except for hepatocellular carcinoma was quantitated. In the real-time PCR, fluorescence was undetectable in any of the controls. On the contrary, fluorescent signals were detected in 10 out of 39 blood specimens collected from 23 HCC patients. AFP-positive status was significantly associated with the existence of multiple intrahepatic nodules. Out of 8 cases with AFP-positive status, intra- and/or extra-hepatic recurrence has been observed in 3 cases. The quantities of AFP messenger RNA in these 3 cases were relatively high among 8 cases with AFP-positive status. AFP messenger RNA was detectable by newly developed real-time PCR approach with LightCycler and it is suggested that this approach could be applicable in detection of small amounts of tumor cells in the blood of HCC patients.

A 54-year-old man underwent an operation for colon cancer histologically diagnosed as moderately differentiated adenocarcinoma with clinical staging of Dukes C. He was prescribed carmofur for adjuvant chemotherapy. A follow-up computed tomography scan done 6 months later revealed two new low-density areas in the liver. A diagnosis of metastatic adenocarcinoma from the previous colon cancer was presumed, based on the patient's history and radiological findings, and resection of the affected area of liver was performed. Histological examination of these tumors revealed that they were inflammatory pseudotumors (IPT). The patient had an excellent postoperative course and has shown no further signs of recurrence in the 3 years since his last operation. IPT of the liver is a rare disease, for which no methods of diagnosis and treatment have been established, since it is difficult to distinguish IPT from hepatocellular carcinoma or metastatic carcinoma. We describe this case with a review of the 101 cases of IPT documented in the Japanese literature, in the hope that it will contribute to the diagnosis and treatment of this unusual disease entity.

Interferon-alpha (IFNalpha) plays a crucial role in the antiproliferation and immunoregulatory activity through the specific cell surface receptor, interferon-alpha/beta receptor (IFNalpha/betaR). We examined the immunohistochemical expression of IFNalpha/betaR in 91 hepatocellular carcinoma (HCC), HCV-related chronic hepatitis (n=38) and cirrhosis (n=53), dysplastic nodules (n=5), and normal liver (n=9). The level of IFNalpha/betaR increased in chronic hepatitis and cirrhosis compared with normal liver. All the dysplastic nodules showed moderate or high expression. In HCCs, 26% (24/91) of patients showed high IFNalpha/betaR expression while the remaining 38% (35/91) showed moderate, and 35% (32/91) no or faint expression. Clinicopathological survey demonstrated a significant correlation between IFNalpha/betaR expression and differentiation of carcinoma (P=0.0008) although there was no correlation between IFNalpha/betaR expression in HCC and survival or disease-free survival. Thus, IFNalpha/betaR was expressed not only in chronic hepatitis or liver cirrhosis but in HCC and its expression was significantly correlated with tissue differentiation of carcinoma.

Hepatocellular carcinoma (HCC) is likely to be detected as multiple intrahepatic metastases, and trans-arterial embolization (TAE) is the treatment of choice. However, other therapy is needed when TAE is not effective for a tumor. We performed partial liver resection with small skin incision in two such patients. One patient had two HCCs of segment 6 (S6) and S7, and TAE was performed twice. However, HCC of S7 was viable, and we partially resected the tumor of S7. In the other patient, HCC was multiple in segment 6 and 7. TAE was performed three times, and in segment 6 we detected a tumor which grew into the extrahepatic space and seemed uneffected by TAE. We performed a partial resection of liver segment 6. After 3 months, TAE was repeated in the latter. The operation time was about three hours, and no blood transfusion was performed. Two of the patients were discharged on the 13th postoperative day. We concluded that partial liver resection with small skin incision was useful for one case of multidisciplinary treatment for hepatocellular carcinoma.

The conventional methods (CM) of intraarterial (IA) chemotherapy for inflammatory breast cancer were catheterizations from superior epigastric and brachial artery under general anesthesia. Since 1997, we selected the Seldinger's methods (SM) for ten cases of the disease to control local effects and simplify the technique. Complications of the SM were slight, and side effects were equal to those with CM. The postoperative pathological findings of the SM showed the direct effects of chemotherapy to tumor cells (degenerative and necrotic changes) as compared with the embolism-like effects of CM. But the overall histological effects of chemotherapy by SM were almost equal to those for CM. The strong points of the SM were as follows: 1) More selective IA chemotherapy is available, 2) one can find the passage of the aim vessels and no trouble related to catheter, 3) general anesthesia is not necessary, and the techniques are simple, 4) the wounds are not remarkable. The disadvantages are as follows: 1) Patients must rest the day of IA chemotherapy, 2) in 20% of the procedures, one can not search the vessels, and 3) in 4 cases complications of stiffness of Mj or Mn pectral muscles were found. In future, we expect more effective results by dose escalation or combination chemotherapy.

Recently microwave tissue coagulation therapy (MCT) has been established as a therapeutic procedure for hepatocellular carcinoma (HCC). The route of approach to penetrate the tumor is two-fold: By the percutaneous route (PMCT) or by conventional laparotomy. PMCT has the advantage of less invasive therapy, however, it is not applicable to a tumor that cannot be detected by ultrasonography. Therefore, we tried MCT with mini-laparotomy. The patient was a 57-year old man with HCC located in the S6 subsegment. The operation was performed at the semi-right side up position, and laparotomy was done by skin incision of 12 cm in the right hypochondral area. MCT was performed about 30 times, with an output of 60 watts for 45 seconds at a time. Abdominal CT image showed a low-density area of 7 x 4 cm on the 18th postoperative day. Slight damage to the liver and no obvious complications were observed. We concluded that a much wider range-coagulation than PMCT was able to be obtained by MCT with mini-laparotomy, and postoperative quality of life was better than MCT with conventional laparotomy.

Hepatic arterial chemotherapy was performed for 27 patients with primary (3), metastatic liver cancer (21), and 3 other cases, over a period of 8 years. Chemotherapy was performed by intermittent hepatic arterial infusion of 5-FU or FAM (in case of metastatic tumor from colorectal cancer), FAM (from gastric cancer), and CDDP or Farmorubicin (HCC). Hepatic resection was performed in 10 cases of metastatic tumor from colorectal cancer, and 8 cases of 10 were curative operation. The 5-year survival rates of curative liver resection group, and non-curative liver resection or non-resection group were 57.1% and 12.5%, respectively. As is the case with metastatic cancer from gastric cancer, pancreatic cancer, and hepatocellular carcinoma (HCC), the prognosis was poor except for one CR case of HCC. We concluded that hepatic arterial chemotherapy may be recommended for a curative resected case of liver metastasis from colorectal cancer.

The patient was a 68-year-old male, who underwent total gastrectomy for giant leiomyosarcoma of the stomach and then had multiple hepatic metastases one year and six months later. Thus, transarterial hepatic chemo-embolization therapy with Lipiodol, adriamycin and gelfoam was given. Moreover, using a reservoir catheter and infusion arterial port, intermittent arterial infusion therapy with adriamycin, cyclophosphamide, and vincristine was attempted. In the metastasis lesion where there were rich blood vessels, Lipiodol was accumulated and the tumor was reduced on abdominal CT. The result indicated the efficacy of this treatment.

Acute angle-closure glaucoma is a rare complication of surgery. We experienced a case of postoperative acute glaucoma after total hip replacement under general anesthesia. A 49-year-old female without signs or symptoms of glaucoma was premedicated with the intramuscular administration of secobarbital, atropine and ranitidine. Following rapid induction with thiopental and vecuronium, anesthesia was maintained with N2O-O2-sevoflurane. PGE1 was administered intravenously for induced hypotension during the surgery. Hemorrhagic shock with a systolic blood pressure of 60 mmHg continued for 15 min during the surgery. Large amounts of fluid and ephedrine were required for treating this hypotensive episode. Vecuronium was reversed by bolus injection of neostigmine and atropine at the end of surgery. Soon after recovery from anesthesia, she complained of pain and blurred vision in her both eyes. The consulting ophthalmologist made a diagnosis of acute glaucoma due to high intraocular pressure (IOP). Treatment with glycerol and pilocarpine had no effect on the elevated IOP. The laser iridotomy performed on her at 5th and 7th post-operative days improved her vision completely. The post-operative glaucoma may cause serious permanent loss of vision. An early diagnosis of this post-operative complication and its treatment with drugs and surgery should be emphasized.

BACKGROUND: The finding that i.v. lidocaine suppresses cardiac sympathetic nerve activity during 1 MAC halothane, but not during 2 MAC or 3 MAC halothane, suggests that the neurally mediated circulatory effects of i.v. local anesthetics may vary with background autonomic activity. This study aimed to compare the effects of i.v. lidocaine and bupivacaine on cardiac sympathetic nerve activity (CSNA) during normal and high levels of CSNA. METHODS: Cats were anesthetized with halothane and allocated to three groups. In groups I-L and I-B, sympathetic hyperactivity was induced by electrical stimulation of the posterior hypothalamus. CSNA, heart rate and mean arterial pressure were then measured before and after administration of lidocaine 2 mg.kg BW-1 i.v. (Group I-L, n = 7) or bupivacaine 0.5 mg.kg BW-1 i.v. (Group I-B, n = 7) during 1% halothane anesthesia. In Group II (n = 7), following administration of bupivacaine 0.5 mg.kg BW-1 i.v., CSNA, sinus cycle length (SCL), and subintervals of atrioventricular conduction time (A-H, H-V, and H-S) at pacing were measured during 0.8%, 1.6% and 2.4% halothane anesthesia without sympathetic hyperactivity. RESULTS: Lidocaine suppressed CSNA hyperactivity and tachycardia significantly in Group I-L, but bupivacaine did not do so in Group I-B. In Group II, bupivacaine did not affect CSNA at any concentrations of halothane, but lengthened SCL, A-H, H-V and H-S intervals significantly at each concentration of halothane. CONCLUSIONS: We conclude that i.v. bupivacaine, unlike i.v. lidocaine, does not suppress CSNA during either normal or high CSNA under halothane anesthesia although i.v. bupivacaine has stronger depressive effects on cardiac conduction than does i.v. lidocaine during deep halothane anesthesia.

Malignant hemangioendothelioma of the lung is very rare and difficult to diagnose. The growth is rapid and the prognosis is very unfavorable. We report an operated case of the disease with rapid growth of pulmonary metastasis. The silver, vimentin and factor VIII stainings were available for diagnosis of this disease. The 46-year-old female patient died of bleeding from the pulmonary metastasis eight months after the operation without other distant metastasis. Even if a lung tumor is pointed out and thought to be benign, frequent follow up is necessary. Furthermore, we recommend positive lung biopsy by thoracotomy or video-assisted-thoracic-surgery.

BACKGROUND AND OBJECTIVES: Because hemodynamic responses to systemic mepivacaine may be influenced by sympathetic change and concurrent general anesthesia, the authors directly measured renal sympathetic nerve activity (RSNA) during intravenous administration of mepivacaine in subseizure through seizure doses under N2O-O2 and N2O-O2-halothane anesthesia. METHODS: Thirty-four cats were randomly assigned to five groups. Groups I-A, I-B, and I-C received incremental subseizure doses of intravenous mepivacaine (2 mg/kg, 5 mg/kg, and 10 mg/kg). Groups II-A and II-B received intravenous infusion of mepivacaine (4 mg/kg/min). Anesthesia was maintained with N2O(70%)-O2 in groups I-A, I-C, and II-A, and with N2O(70%)-O2-halothane (1%) in groups I-B and II-B. Cats in group I-C had undergone total baroreceptor denervation. Heart rate (HR), mean arterial pressure (MAP), and RSNA were measured. RESULTS: In group I-A, MAP did not significantly change with intravenous mepivacaine, though RSNA and HR significantly decreased (P < .05) respectively with 5 mg/kg i.v. and 10 mg/kg i.v. mepivacaine. In group I-C, HR, MAP, and RSNA did not change significantly. In group I-B, HR and MAP decreased with bolus intravenous doses of mepivacaine in a dose-dependent fashion, but RSNA did not change significantly. All cats in group II-A developed seizure by mepivacaine infusion at mean total dose of 28.9 +/- 4.2 mg/kg without significant changes in HR, MAP, or RSNA. In group II-B, mepivacaine infusion resulted in circulatory collapse at mean total dose of 34.3 +/- 4.6 mg/kg without seizure or significant RSNA change. CONCLUSIONS: The authors conclude that intravenous mepivacaine induces occasional depression in HR and RSNA during N2O-O2 anesthesia, but in addition induces dose-related circulatory depression during N2O-O2-halothane anesthesia via nonsympathetic mechanism(s).

A 76-year-old woman with a history of repeated right-sided cardiac failure during the past 2 years presented with tricuspid and mitral regurgitation due to congenital hypoplasia of atrioventricular valves. Two-dimensional echocardiography demonstrated enlarged right atrium and right ventricle, and discoaptation between the leaflets. Color Doppler echocardiography revealed severe tricuspid regurgitation through the gap between the leaflets. Autopsy showed congenital hypoplasia of the leaflets and the chordae tendineae in the tricuspid and mitral valvular apparatus.

To study neural contributions to the alterations in intracardiac conduction induced by i.v. lidocaine, we measured cardiac sympathetic nerve activity (CSNA) simultaneously with sinus cycle length (SCL) and A-V cats. Sixteen cats were anesthetized with halothane in oxygen and mid-sternotomized. The His-bundle electrogram and CSNA were recorded from an electrode placed in the interatrial septum and from the left ventrolateral or ventromedial nerve, respectively. Atrium-His (A-H), His-Purkinje (H-V), and total intraventricular (H-S) conduction times were measured during atrial pacing conducted at a cycle length of 300 ms. In eight cats, 1 MAC, 2 MAC, and 3 MAC halothane were given during i.v. lidocaine (Groups H-1, H-2 and H-3). In the other eight cats, anesthesia was switched from halothane to i.v. alpha-chloralose (30-50 mg.kg BW-1; Group C). A significant decrease in CSNA with i.v. lidocaine, 2 mg.kg BW-1 was recognized in Groups C and H-1, but not in Groups H-2 and H-3. Prolongations of SCL during the spontaneous cycle, A-H and H-V in the paced mode following i.v. lidocaine were significant in Groups C, H-1 and H-2, but not significant in Group H-3. We conclude that i.v. lidocaine induces a significant decrease in CSNA during alpha-chloralose or 1 MAC halothane anesthesia which partly contributes to the control of intracardiac conduction.

Prognostic studies were performed on 17 cases with clear cell carcinoma of the ovary. The results are follows: 1) The average age was 45.9 years and ranging from 35 to 57 years. 2) Regarding the FIGO clinical stage, all of 5 patients with stage I and 3 of 5 with stage II survived over 2 years, while all of patients with stage III and 2 with stage IV were dead within 2 years. 3) Of 9 patients who had complete resection for primary operation, 8 (89%) survived over 2 years. All of 8 patients who had incomplete resection were dead within 2 years. 4) All cases had been received various chemotherapy; CQ + 5-FU (n = 5), CPM + ADM + CDDP + 5-FU (n = 7), 5-FU + CPM + MMC (n = 2), CDDP (n = 1), CDDP + MMC + 5-FU (n = 1), MCNU + VCR + 5-FU (n = 1), but none of them improved the prognosis of this histological type. 5) With or without administration of CDDP, there was no significant difference in the prognosis. These results suggest that early diagnosis of disease, curative surgical resection and selection of effective chemotherapeutic agents are important things to improve prognosis of clear cell carcinoma of the ovary.

The dose limiting factors of cisplatinum are nephrotoxicity and emesis. Nephrotoxicity has been reduced by hydration but nausea and vomiting caused by cisplatinum have led to refusal of potentially curative therapy by a number of patients. The prevention of nausea and vomiting by a combination of antiemetic drugs administered to ovarian patients receiving chemotherapy inducing (cisplatinum 50mg/m2, adriamycin 300 mg/m2, cyclophosphamide 300 mg/m2 and 5FU 350 mg/m2) was studied. the combination antiemetic drugs were metoclopramide (1mg/kg), dexamethasone (10mg/m2), droperidol (1mg/m2) and diphenhydramine (20mg/body). These drugs without diphenhydramine were administered intravenously 30 minutes before and 2.5 hours, 5 hours and 7.5 hours after chemotherapy. Diphenhydramine was administered intramuscularly 30 minutes before and 5 hours after chemotherapy. No vomiting was noted in 82.6% (19/23) of cases, and no patient vomited more than four times. This combination regimen provided very good protection against cisplatinum induced emesis.

Ceftriaxone (CTRX) was studied regarding its penetration into the adnexa uteri and uterine tissues, as well as its utility and safety in the treatment of patients with obstetric and gynecologic infections. The results obtained are summarized below. 1. When 1 g of CTRX was administered by intravenous bolus injection, Cmax in tissues of adnexa uteri and uterus ranged from 42.2 to 80.5 micrograms/g, Tmax ranged from 0.42 to 0.81 hour, and the AUC ranged from 314.9 to 606.9 micrograms.hr/g. Thus, drug penetration into these tissues was good. 2. Clinical efficacy of CTRX was evaluated in 29 obstetric and gynecological patients. The clinical efficacy was good in all cases. 3. Bacteriological effects of CTRX were very good, and 90% of the organisms isolated before treatment were eradicated. 4. Laboratory testing revealed an occurrence of mild eosinophilia in 1 case.

The distribution of cefuzonam (CZON, L-105) into the uterus and uterine adnexa was investigated and the usefulness and the safety of CZON in obstetric and gynecological infections were studied. The results are summarized as follows: 1. Following one shot intravenous injection of CZON 1 g, a good distribution of the drug into tissues of uterus and uterine adnexa was observed, with Cmax values of 15.7-33.9 micrograms/g, Tmax of 7.3-34.0 minutes and AUC values of 18.7-35.3 micrograms X hr/g. 2. In all of the 30 cases of obstetric and gynecological infections treated, CZON was evaluated effective. 3. Bacteriologically, 93.9% of total bacteria that had been isolated were eliminated by the administration of the drug. 4. Against all the strains of bacteria isolated before the treatment and replaced bacteria, MIC50, MIC80 and MIC90 of CZON were 0.20 micrograms/ml, 12.5 micrograms/ml and 25 micrograms/ml, respectively, showing low values. 5. Subjective and objective findings and clinical laboratory test values during and after the trial showed no side effects associated with CZON.
