Recognition of adrenal atrophy during a review of autopsy findings in two sisters who died at 8 months and 3 1/2 years prompted estimation of very long chain fatty acids, phytanic acid and pristanic acid on wet liver fixed in formalin for 12 years. These were shown to be markedly increased and defects in multiple peroxisomal functions and decrease in particulate catalase were shown in cultured fibroblasts, confirming an abnormality of peroxisomal biogenesis. The patients had presented with failure to thrive, recurrent diarrhoea and vomiting, poor mental development, retinal pigmentation, blindness and in the older patient deafness, with only mild dysmorphic features. Autopsy in the older patient showed adrenal atrophy, cirrhosis, and foamy histiocytes in multiple organs. The brain showed no demyelination, little cytoarchitectural abnormality, occasional perivascular histiocytes in the grey matter and meninges and prominent Purkinje cells in the molecular layer of the cerebellum. In the younger patient the changes were very subtle in spite of the marked clinical similarity. Despite the young age at death the clinicopathological features are most suggestive of infantile Refsum disease. In many situations anatomical pathology can be very useful in the recognition and study of peroxisomal disorders.

The case is described of a 33-year-old woman with an 8-year history of oral contraceptive (OC) use who was treated at a hospital in Buenos Aires for a hepatic adenoma. The woman was admitted with an acute abdomen. Apart from OC use she had a history of hypertension for which she was treated with clonidine and diuretics. The physical findings included pain in the right abdomen, involuntary guarding, vomiting, and fever. Ultrasonography showed a normal bladder and pancreas and a nodular image in the right hepatic lobe. A CAT scan revealed a mass in the right hepatic lobe, and a needle biopsy later showed normal hepatic cells. Laparoscopy revealed a solid formation from which blood was obtained on puncturing. Angiography showed tortuous hepatic arteries. Laboratory tests were normal. An exploratory laparotomy was performed when the different studies failed to establish a clear diagnosis. A tumor was found in the right hepatic lobe but was not respected because the frozen section biopsy did not show malignant cells. The definite diagnosis of hepatic adenoma was based on the definitive biopsy. OC treatment was terminated and the tumor was in almost complete remission 1 year later. Hepatic adenomas are benign tumors, usually single, which occur rarely and primarily in women aged 30-40 who use OCs. A review of the literature indicated that the forms of presentation of hepatic adenoma are very varied. Pain was the initial symptom in 12-52% of cases. The pain was of sudden onset in 1/3. Hepatic adenoma is however infrequently considered as a cause of acute abdomen. Treatment in 73% of cases is surgical because of the danger of hemorrhage and shock and because of the potential for malignant transformation.

After ingestion of an unknown amount of a gun blueing compound containing selenious acid (11 ml from the bottle fluid were missing, equivalent to 2.9 g Se) a 2-year-old girl suffered from continuous hyper-salivation, vomiting, diarrhoea, restlessness and muscle spasm. Blood pressure and pulse rate were increased. Symptomatic treatment was performed by parenteral fluid administration. The plasma Se concentration was increased to 20 times normal 5 h after ingestion. Erythrocyte Se exceeded plasma Se, 24 h after intoxication. Urinary Se excretion decreased parallel to the plasma Se concentration. Ten weeks later, the Se content of hair had risen to 10 times normal. The plasma glutathione peroxidase activity showed only a slight increase during the first 36 h, erythrocyte glutathione peroxidase, catalase and superoxide dismutase activities were not significantly altered. The child fully recovered.

A 32-year-old woman with a contraceptive history of use of combination contraceptives (Oviston, Non-Ovlon) between 1966 and 1979 (with a 1-year interruption), followed by radical hysterectomy in 1979, complained of dull right upper quadrant pain, nausea, vomiting, and fatigue in 1980. Among various diagnostic studies performed only cholecystography and cholangiography demonstrated clear areas in the gallbladder assumed to be stones. Cholecystectomy performed in 1981 showed chronic inflammation of the gallbladder without stones. The undersurface of the liver revealed a greyish tumor (3 cm in diameter). Frozen section demonstrated mature hepatocellular adenoma. Wedge excision of the tumor and cholecystectomy were performed without complications. CAT-scan follow-up showed no residual pathology. Additional literature search reports 58 cases in western European and American journals. Diagnosis of these benign tumors is difficult because the symptoms are vague. The main complication is intraabdominal hemorrhage necessitating emergency lobectomy. Ligation of a branch of the hepatic artery is done in case of inoperability. CAT-scan and ultrasonography with selective angiography are the best procedures to ascertain the diagnosis. Needle biopsy is contraindicated because of the risk of hemorrhage.

A 65-year-old man was referred from a medical unit for psychiatric assessment of a depressive illness associated with intermittent vomiting. No organic disorder was identifiable after the initial clinical examination and extensive investigations. A primary lymphoma involving the limbic system was eventually detected on repeat CAT scan and was confirmed at autopsy. This tumour, which is increasing in incidence, is notoriously difficult to diagnose and frequently presents with combined psychological and organic symptoms. It may be radiosensitive if detected early enough.

Primary amebic meningoencephalitis and granulomatous amebic encephalitis are well recognized clinicopathological entities caused by free-living amebas. Associated arteritis and "mycotic aneurysms" with infiltration of intracranial arteries by lymphocytes, amebic trophozoites and cysts have not been previously reported. A 26-month-old girl had a 3-week history of encephalitis, characterized, initially, by vomiting and low-grade fever. Subsequently, she developed ataxia, generalized weakness, lethargy, and esotropia. The first CSF showed 490 RBC/microliters, 705 WBC/microliters with 90% mononuclears. Her pupils reacted briskly to light. Moderate nuchal rigidity, nystagmus, fixed downward gaze, anisocoria, bilateral 6th nerve palsy, left arm monoparesis and left Babinski were present. CAT scan revealed slight symmetrical dilatation of anterior horns of lateral ventricles and an area of abnormal enhancement above the 3rd ventricle. She died 14 days after admission, 5 weeks after onset of symptoms. The brain showed focal necrotizing encephalopathy, involving thalami, cerebellum, brain stem, and cervical and upper thoracic spinal cord. Numerous free-living amebic trophozoites and cysts were present within a chronic granulomatous encephalitis. There were trombosis of basilar, posterior cerebral, and vertebral arteries with profuse chronic panarteritis, fibrinoid necrosis, and mycotic aneurysms.

The case of a 26 year old woman who had been taking tranexamic acid to prevent uterine bleeding due to an IUD and who died from thrombosis of the left internal carotid artery is reported. The patient's father had died at age 54 of myocardial infarction. Otherwise the family history was entirely negative for thromboembolic disease. The patient was a mild smoker. She had been previously healthy and in particular, she was not affected with hypertension, diabetes, or dyslipidemia. She had carried to term 2 uncomplicated pregnancies. 40 days prior to hospital admission her gynecologist had inserted an IUD. The insertion of the IUD was followed by persistent uterine bleeding, and for this reason she began treatment with tranexamic acid (1.5 g/daily). Uterine bleeding persisted despite this treatment, and the IUD was removed. Because of persistence of a mild uterine bleeding, tranexamic acid was continued. 2 hours before admission the patient suddenly presented a left sided hemiparesis with disarthria and vomiting. On admission she was stuporous. The left side of her face drooped and the strength of the left arm and leg was markedly decreased. Both arm and leg reflexes were symmetrical. Her blood pressure was 110/70. An electroencephalogram on arrival confirmed a right sided cerebral lesion. Subsequently the patient's condition deteriorated rapidly. She developed a full left hemiplegia and became deeply comatose. A CAT scan performed 4 hours after admission showed no abnormalities. A CAT scan performed 3 days after admission showed a large cerebral infarction involving nearly the whole right cerebral hemisphere. The patient's condition remained essentially unchanged until she died 6 days after admission. Permission for autopsy was refused. Antifibrinolytic drugs competitively inhibit plasminogen activators and noncompetitively plasmin. Thromboembolic complications after the administration of antifibrinolytic drugs have long been recognized. The use of IUDs is often associated with troublesome uterine bleeding and particularly excessive menstrual bleeding. To avoid these complaints, antifibrinolytic drugs are increasingly used.

The participation of free radicals in cisplatin-induced emesis was investigated in the house musk shrew, Suncus murinus. Thiobarbituric acid (TBA) values, which indicate the degree of lipid peroxidation, in brain, liver and small intestine were increased significantly 60 min after the treatment with cisplatin (20 mg/kg, i.p.). Moreover, cisplatin (20 mg/kg, i.p.)-induced emesis was prevented by intraperitoneal injection of N-(2-mercaptopropionyl)glycine (MPG), a radical scavenging agent, with ID50 value of 130 mg/kg. However, MPG did not block the emesis induced by copper sulfate (40 mg/kg, p.o.), veratrine (0.5 mg/kg, s.c.) or serotonin (10 mg/kg, i.p.). We also investigated the effects of superoxide dismutase conjugated to polyethylene glycol and catalase, but the number of vomiting episodes and latency did not change significantly when these agents were intraperitoneally injected 30 min prior to or 20 min after the administration of cisplatin. MPG did not affect the antitumor effect of cisplatin tested in vitro. These results suggest that free radicals mediate emesis caused by cisplatin and that radical scavengers may become a new class of prophylactic drug against cancer-chemotherapeutic drug-induced emesis.

On the basis of biochemical, phenotypic, and 16S rRNA analysis, a novel gram-negative bacterium, isolated from normal and diarrheic dogs as well as humans with gastroenteritis, has been recently named Helicobacter canis. A 2-month-old female crossbred puppy was submitted to necropsy with a history of weakness and vomiting for several hours prior to death. The liver had multiple and slightly irregular yellowish foci up to 1.5 cm in diameter. Histologically, the liver parenchyma contained randomly distributed, occasionally coalescing hepatocellular necrosis, often accompanied by large numbers of mononuclear cells and neutrophils. Sections of liver stained by the Warthin-Starry silver impregnation technique revealed spiral- to curve-shaped bacteria predominantly located in bile canaliculi and occasionally in bile ducts. Aerobic culture of liver was negative, whereas small colonies were noted on Campylobacter selective media after 5 days of microaerobic incubation. The bacteria were gram negative and oxidase positive but catalase, urease, and indoxyl acetate negative; nitrate was not reduced to nitrite, and the organism did not hydrolyze hippurate. The bacteria were also resistant to 1.5% bile. Electron microscopy revealed spiral-shaped bacteria with bipolar sheathed flagella. By 16S rRNA analysis, the organism was determined to be H. canis. This is the first observation of H. canis in active hepatitis in a dog and correlates with recent findings of Helicobacter hepaticus- and Helicobacter bilis-related hepatic disease in mice. Further studies are clearly warranted to ascertain whether H. canis-associated hepatitis is more widespread in canines as well as a cause of previously classified idiopathic liver disease in humans.

Lately, myeloprolipherative disorders are frequently reported as causes of portal vein thrombosis, probably due to the early detection of latent cases of this condition. We report two patients with portal vein thrombosis that presented with abdominal pain, nausea, vomiting and clinical consequences of portal hypertension such as variceal hemorrhage, splenomegaly and ascites. Diagnosis was made by a CAT scan in one patient and doppler ultrasound in the other. Both patients had high platelet counts and an essential thrombocytosis in the bone marrow.
