Protective effect of cysteine and vitamin E, Crocus sativus and Nigella sativa extracts on cisplatin-induced toxicity in rats

There are three ways to approach and resect the caudate lobe of the liver, that is; and isolated caudate lobectomy, a combined resection of the liver overlying the caudate lobe, and a transhepatic anterior approach by splitting parenchyma of the liver. We had two patients with neoplasms originating in the caudate lobe who underwent a complete caudate lobectomy. Both patients have been doing well without liver dysfunction. Although after the transhepatic anterior approach we anticipated an adverse effect from splitting the parenchyma of the liver, the postoperative course was uneventful and similar to that of the right side approach.     

Primary retroperitoneal germ cell tumours: excision via a thoracoabdominal extraperitoneal approach

BACKGROUND: Primary retroperitoneal germ cell tumours usually present as a large abdominal mass in young men. The testes are normal on examination and ultrasonography but there are usually raised serum levels of human chorionic gonadotrophin and/or alpha-fetoprotein. METHODS: Fourteen men (median age 33 years) with primary retroperitoneal germ cell tumours were treated by chemotherapy followed by surgical resection of the primary tumour and metastases via a thoracoabdominal extraperitoneal approach. RESULTS: There was minimal morbidity. The survival rate was 13 of 14 and the disease-free survival rate was 11 of 14 after a median follow-up of 15 months. CONCLUSION: The thoracoabdominal extraperitoneal approach for the removal of retroperitoneal germ cell tumours and their metastases after chemotherapy improves tumour clearance, morbidity and recovery time compared with the transperitoneal anterior approach.     

Ambulatory urodynamics

Ambulatory monitoring of lower and upper urinary tract continues to develop. The addition of electronic urine-loss measurements to indicate the exact time-related loss is an important new feature. In the near future, quantitative urine-loss measurements will become available. The additional possibility of plugging in a flowmeter completes the technique with respect to pressure-flow analysis. At present, however, ambulatory urodynamics is still confined to specialized urodynamic centers. Ambulatory urodynamic monitoring has shown that de-novo detrusor instability after a suspension operation is frequently missed as a preoperative diagnosis of detrusor overactivity. The first steps are being taken toward giving a quantitative analysis of detrusor activity during the filling phase. This justifies a more widespread use of this ambulatory monitoring.     

Corneal endothelial cell measurements in megalocornea

A pedigree of megalocornea manifested many of the characteristic features as well as some less common features of the disorder. Endothelial specular microscopy of affected patients disclosed normal endothelial cell densities and morphologic characteristics and increased total endothelial cell populations, suggesting a process of total corneal hyperplasia. In contrast, unpublished data indicate diminished densities in congenital glaucoma, a finding more consistent with corneal distention. We conclude that specular microscopy may be of value in differentiating the two disorders, although larger series are necessary for confirmation.     

Metastasis of malignant melanoma of the nasal mucosa to the small intestine

Malignant melanoma of the mucous membranes is rare and has a very poor prognosis. When localized in the nose, the tumor becomes apparent late in the course of the disease with nasal obstruction and epistaxis. Distant metastases are uncommon, but any organ of the body can be involved. A case of a malignant melanoma of the nasal mucosa with metastasis to the small intestine is presented, and the natural history of the metastatic disease is discussed.     

Intellectual deficits after transient tyrosinemia in the term neonate

An analysis was made of the obstetric history of 1,360 patients who were delivered in 1971. It involved 3,185 pregnancies. The aim of the study was to evaluate the risk of spontaneous termination of the pregnancy, worked out from its demographic aspect. Several ideas are worthy of consideration. The risk of spontaneous intra-uterine death is cumulative, sharply increased by a repetition of such cessation of pregnancy. The same patients often undergo intentional abortion repeatedly. The respective risks of spontaneous and provoked interruption of pregnancy have been studied in greater detail as a function of parity.     

Survey of impaired drivers, fatally injured or surviving, who caused fatal highway accidents in Alberta in 1970-72

In 1970-72, 456 (53.4%) of 854 drivers responsible for a motor vehicle accident in which either they or other persons were killed had been drinking beforehand. Of surviving culpable drivers tested for blood alcohol concentration 81.7% were found to be legally impaired; however, only 24.8% of these drivers were tested. Because surviving culpable drivers pose a possible future hazard to highway safety it is important that data on this group be collected and analysed.     

The Maine Scale of paranoid and nonparanoid schizophrenia: Reliability and validity.

Examined the Maine Scale (MS) in 3 studies (131 18–60 yr old hospitalized psychiatric patients) in which adequate test–retest and independent interrater reliabilities were obtained. In an examination of construct validity, high scores on the Nonparanoid subscale were associated with external locus of control; poor performance on the Stanford-Binet Intelligence Scale Vocabulary, the Expanded Similarities Test, and the Embedded Figures Test; conceptual overinclusion; slow RT; deviant word associations; and poor recall of word associations. In an examination of concurrent validity, the MS Paranoid and Nonparanoid subscales correlated significantly with the corresponding subscales of the Symptom Rating Scale and the Symptom-Sign Inventory. The MS subscales also correlated significantly with the Weighted Symptom-Sign Inventory and the New Haven Schizophrenia Index but were better able to discriminate between paranoid and schizophrenic categories than any of the other scales. Factor analyses showed a schizophrenic and paranoid factor in both studies. (35 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
