Surgery duration of MicroTESE is much longer than TESE: h (range: - h) in case of positive retrievals and h (range - h) in case of negative retrievals (Ramasamy, 2011), therefore requiring usually general anesthesia and sometimes an overnight stay in hospital. In our series of 740 MicroTESE, the mean operative time for monolateral successful MicroTESE was ' (range: 60-140'), and for bilateral successful or unsuccessful MicroTESE was ' (range: 85-200'). Compared to multiple TESE, which is believed to be more dangerous for testis, due to possible blood supply lesions (Schlegel, 1997) or intratesticular edema or hematoma (Silber, 2000), MicroTESE is now considered the safer procedure, with a lower incidence of bleeding (Schlegel, 1999; Okada, 2002) and postoperative complications such as hematomas, fibrosis and reduced orchidometry, as assessed by sonography (Amer, 2000; Okada, 2002; Ramasamy, 2005; Deruyver, 2013). In our series of 740 MicroTESE, only one hematoma occurred (due to hemostasis during hypotensive state, not communicated by anesthesiologist, and successfully treated without any subsequent damage); no infection, no post-surgical testis hypotrophy or pain, not even in cases where we performed two MicroTESE on the same testis to increase parenchyma exploration. Furthermore, no differences versus TESE were shown about possible post-operative hypotestosteronemia (Okada, 2002; Ramasamy, 2005; Deruyver, 2013).
Peripheral artery disease is caused by the build-up of cholesterol plaques in arteries of the legs. Plaque blocks arteries, reducing the flow of oxygen-carrying blood through the arteries to the muscles. This causes pain upon walking and reduces mobility. Peripheral artery disease is similar to coronary artery disease in which plaque builds up in heart arteries, causing chest pain ( angina ) because of a reduced supply of oxygen to the heart's muscle. Pentoxifylline, through unknown mechanisms, decreases the "stickiness" (viscosity) of blood and thereby improves its flow through arteries. This increases the flow of blood and oxygen to muscles and helps patients with intermittent claudication .
The classic histologic features of alcoholic hepatitis include inflammation and necrosis, which are most prominent in the centrilobular region of the hepatic acinus ( Figure 2 ). Hepatocytes are classically ballooned, which causes compression of the sinusoid and reversible portal hypertension. The inflammatory cell infiltrate, located primarily in the sinusoids and close to necrotic hepatocytes, consists of polymorphonuclear cells and mononuclear cells. In addition to inflammation and necrosis, many patients with alcoholic hepatitis have fatty infiltration and Mallory bodies, which are intracellular perinuclear aggregations of intermediate filaments that are eosinophilic on hematoxylin-eosin staining. Neither fatty infiltration nor Mallory bodies are specific for alcoholic hepatitis or necessary for the diagnosis. 16
