Liver pathology associated with the use of anabolic-androgenic steroids

Abstract: This review examines the liver-damaging side effects of anabolic-androgenic steroids (AAS). It seems that AAS can cause development of peliosis hepatis, subcellular changes of hepatocytes, hepatocellular hyperplasia and hepatocellular adenomas. On the other hand, it has not been convincingly proved that AAS can cause development of hepatocellular carcinomas when used in the usual therapeutic doses. Tumours reported as hepatocellular carcinomas caused by AAS seem to be hyperplastic lesions of a benign nature able to regress with withdrawal of the putative agent. The effects of untraditional combinations and high-dose AAS are not yet known, leaving the possibility of a carcinogenic effect in those cases.     

THE DIAGNOSIS AND TREATMENT OF PSOAS ABSCESS: A 12 YEAR REVIEW

Over a 12 year period, 25 psoas abscesses occurring in 17 patients were managed at Royal Perth Hospital (900 bed hospital). Symptoms were present, on average, for 5 weeks prior to diagnosis, which was typically confirmed by computerized tomography. Fifty-nine per cent of cases were primary and percutaneous drainage effected a cure in 80% of all cases. Percutaneous drainage resulted in a non-significant trend towards shorter inpatient stay.     

The use of computed tomography-guided stereotactic techniques in the treatment of brain stem abscesses

A case of a brain stem abscess that was successfully treated using CT guided stereotaxy together with antibiotic therapy is presented. The literature is reviewed and the role of stereotaxy in the treatment of brain stem abscess is discussed.     

Brain abscess in Saudi Arabia

There are significant variations among countries in the incidence of brain abscess. We report here 26 cases of brain abscess treated at the Neurosurgery Department of King Faisal University and Dammam Central Hospital Saudi Arabia over a six year period (1982–1988). This is 2.3% of total admissions to the two neurosurgery departments serving a population of approximately 1.2 million in the same period.Young males were most often affected (M/F ratio 3.3:1; 31% were less than 15 years old, 46% aged between 15–39 years, and 23% older than 40 years). Streptococcus was found to be the most common microorganism (38.4%). Mixed infection was seen in 15.3%, and sterile abscesses were found in 11.5% of the patients after aerobic and anaerobic cultures of the pus. Chronic otitis media and paranasal sinusitis predisposed the patients to abscess formation in 57.6% of the cases. The temporo-parietal area was the commonest site. Epilepsy was a complication in 30.7% of our patients, and the mortality rate was 15.3%.

对２４例不能切除的晚期肝癌采用完全植入式药泵行肝动脉和门静脉双灌注化疗。结果：部分缓解（ＰＲ）１５例（６２．５％），稳定（Ｓ）８例（３３．３％），进展（Ｐ）１例。平均生存期为９．１７月，半年生存率为６６．７％，１年为２５％。在ＡＦＰ＞４００μｇ／Ｌ的１０例中，５例下降。     

Axial tissue diffusion can account for the disparity between current models of hepatic elimination for lipophilic drugs

An assumption of previous models of hepatic elimination is that there is negligible axial diffusion in the liver. We show, by construction of a stochastic model and analysis of published data, that compounds which are readily diffusible and partitioned into hepatocytes may undergo axial tissue diffusion. The compounds most likely to be affected by axial tissue diffusion are the lipophilic drugs for which the cell membranes provide little resistance and which are highly extracted, thereby creating steep concentration gradients along the sinusoid at steady state. This phenomenon greatly modifies the availability of the compound under conditions of altered hepatic blood flow and protein binding. For moderately diffusible compounds, these relationships are similar to those predicted by the simplistic venous-equilibrium model. Hence, the paradoxical ability of the venous-equilibrium model to describe the steady-state kinetics of lipophilic drugs such as lidocaine, meperidine, and propranolol may be finally resolved. The effects of axial tissue diffusion and vascular dispersion on hepatic availability of drugs are compared. Vascular dispersion is of major importance to the availability of poorly diffusible compounds, whereas axial tissue diffusion becomes increasingly dominant for highly diffusive and partitioned substances.This study was supported by the National Health and Medical Research Council of Australia.     

男性肝硬化患者血清睾丸酮、雌二醇水平

本文观察了80例男性肝炎后肝硬化患者。检测了血清睾丸酮（T），雌二醇（E2）水平及E2／T比值的变化。与正常对照组及脑血管意外对照组进行了统计比较，发现E2及E2／T比值升高，T值降低2与对照组间比较均有显著差异，但肝硬化各组间无明显差异。文中分析了检测结果并探讨了与性功能变化的关系。认为性功能降低可能是由于血清睾丸酮水平降低所致。     

Report of a Case of Pericardial Mesothelioma with Liver Metastases Responding Well to Pemetrexed and Platinum-Based Chemotherapy

Pericardial mesothelioma remains a disease with a bleak prognosis. We report the case of a patient with metastases to liver and good response to pemetrexed and carboplatin-based combination chemotherapy and consequent prolonged progression-free survival.     

Subhepatic collections complicating laparoscopic cholecystectomy: Percutaneous management

Ten patients with subhepatic fluid collections complicating laparoscopic Cholecystectomy were successfully treated by interventional radiological procedures. The series included five abscesses, three hematomas, one biloma, and one serous collection. Abdominal pain or fever developed from 3 to 21 days after the laparoscopic intervention. All patients were asymptomatic 72 h after percutaneous drainage and there were no complications related to the procedure. Subhepatic fluid accumulations are common findings after laparoscopic cholecystectomies and have been considered an unreliable indicator of infection or other postoperative complications. However, the significance of these collections should not be underestimated in symptomatic patients. In such cases we propose diagnostic aspiration and drainage, when necessary, to safely and promptly establish the precise diagnosis and treatment. More serious complications can be avoided by early percutaneous intervention.
