Chronic epididymitis and varicocele are frequently observed genital disorders in men consulting for couple infertility, but their impact on semen characteristics at the time of infertility consultation is still a matter of debate. We investigated 652 male partners of couples who had their first infertility consultation between 1999 and 2015 in Argentina. Men with chronic epididymitis （n = 253）, Grade III varicocele （n = 106）, and both conditions （n = 125） were compared with a control group （n = 168） composed of men without these disorders or any other recognized causes of male infertility. We showed that men who presented isolated chronic epididymitis were more likely to have high percentages of low sperm motility and abnormal sperm morphology as well as a high number of white blood cells. Men with isolated Grade III varicocele had low sperm production and motility and an increased percentage of abnormal sperm morphology. Finally, men who simultaneously presented chronic epididymitis with Grade III varicocele had a low sperm motility and increased percentage of abnormal sperm morphology as well as a high number of white blood cells. Physical examination of the genital organs may identify common disorders, potentially involved as causal factors of patient＇s infertility. These disorders are associated with specific seminal profiles that should help in identifying the best treatment from the available therapeutic options, effectiveness, safety, and allowing as much as possible natural conception.

Left Hemispherical Subdural Hematoma on the Same Side as the Motor Deficit (Kernohan)

Open Journal of Modern Neurosurgery 2024年第3期14卷 212-217页

Chronic subdural hematoma represents 25% of traumatic subdural collections;common in elderly subjects with a clear male predominance. It occurs over the age of 50 in more than 90% of cases and 50% of patients have no history of head trauma even if the latter remains the main risk factor with others such as coagulopathy, anticoagulant treatment, chronic alcoholic poisoning. Its discovery is rarely fortuitous and has an important clinical polymorphism including an intracranial hypertension syndrome (complete or incomplete). We report a clinical case of a left hemispheric subacute subdural hematoma with post-traumatic falcorial involvement in a 70-year-old patient admitted with a picture of impaired consciousness and weakness of the left hemibody. The objective of this work is to draw the attention of neurosurgeons and neurologists to the paradoxical existence of the neurological deficit on the same side as the causal brain lesion.

Axial Breakthrough in Ancient Greece. New Considerations： Plato, Confucius, and the Buddha

作者： luc Brisson Directeur de Recherche Emerite au Centre National de la Recherche Scientifique 4 bis rued'Italie 65013 Paris France

Here I will examine the resemblances and similarities between Plato and two other personages, Confucius and the Buddha, who were his near-contempo- raries, and who enabled a breakthrough. The Platonic break with the world of bodies and the sphere of belief, in favor of a level of intelligible realities, the models of the sensible realities explained by mathematics and moved by the soul, explains the specificity of the Western world, in the field of science, politics, ethics, and even religion.

Recent trends in the treatment of well-differentiated endocrine carcinoma of the small bowel

引用

World Journal of Gastroenterology 2010年第14期16卷 1696-1706页

作者： Gilles Poncet Jean-luc Faucheron Thomas Walter Department of Digestive Surgery Edouard Herriot Hospital 69437 Lyon cedex 03 France Department of Colorectal Surgery Michallon Hospital 38043 Grenoble cedex France Department of Medical Oncology Pavillon H Edouard Herriot Hospital 69437 Lyon Cedex 03 France

Well-differentiated endocrine carcinomas of the small bowel are fairly rare neoplasms that present many clinical challenges. They secrete peptides and neuroamines that may cause carcinoid syndrome. However, many are clinically silent until late presentation with major effects. Initial treatment aims to control carcinoid syndrome with somatostatin analogs. Even if there is metastatic spread, surgical resection of the primitive tumor should be discussed in cases of retractile mesenteritis, small bowel ischemia or subocclusive syndrome in order to avoid any acute complication, in particular at the beginning of somatostatin analog treatment. The choice of treatment depends on the symptoms, general health of the patient, tumor burden, degree of uptake of radionuclide, histological features of the tumor, and tumor growth. Management strategies include surgery for cure (which is rarely achieved) or for cytoreduction, radiological interventions (transarterial embolization or radiofrequency ablation), and chemotherapy (interferon and somatostatin analogs). New biological agent and radionuclide targeted therapies are under investigation. Diffuse and non-evolving lesions should also be simplymonitored. Finally, it has to be emphasized that it is of the utmost importance to enroll these patients with a rare disease in prospective clinical trials assessing new therapeutic strategies.

Loco-regional treatments of unresectable hepatocellular carcinoma:safety first

Hepatobiliary Surgery and Nutrition 2022年第2期11卷 324-326页

Hepatocellular carcinoma(HCC)is a severe liver cancer that complicates underlying severe liver *** a long time,palliative treatment of unresectable HCC was loco-regional and based on tumor arterial hypervascularization and intra-tumor retention of Lipiodol when injected *** 1995,it was demonstrated that transarterial chemoembolization(TACE)reduced tumor growth and size,but did not significantly improve survival,because any benefit was offset by worsened liver function(1).Despite the failure to demonstrate improved survival,TACE remained the most commonly used palliative treatment worldwide for many *** 2002,two RCTs demonstrated the efficacy of TACE,but only in highly selected patients(2).The good indications for TACE were limited to certain intermediate stage HCC,PS 0(or possibly 1),with preserved liver function(Child-Pugh A without ascites),without vascular invasion,and had to be carried out in a selective manner to minimize the ischemic insult to non-tumoral tissue(3,4).In scores evaluating survival after a first TACE,the parameters linked to liver toxicity were more important than tumor response!In a recent comparison of TACE with lenvatinib,TACE but not lenvatinib was responsible for a severe decrease in the liver function(evaluating by the ALBI score)from baseline,and this acute deterioration persisted in the chronic period(5).The price to pay for the efficacy of TACE is thus liver function.
