AIMS: Varicocelectomy is the most common operation carried out by doctors for male infertility treatment. The aim of varicocele treatment is to hinder the refluxing venous drainage to the testis, retaining arterial inflow, and lymphatic drainage. A lot of pain is generated after this surgery, and the use of opium should be reduced to nearest minimum, as all drugs are toxins. Thus the aim of the present study is to facilitate morphine usage reduction after varicocelectomy surgery. MATERIAL AND METHODS: One-hundred (100) patients who were varicocelectomy candidate were randomized into two groups: experimental group contain 50 patients and control group contain 50 patients as well...

In the United States, preterm delivery is the leading cause of neonatal morbidity and is the most common reason for hospitalization during pregnancy. The rate of preterm delivery (before 37 weeks' gestation) has been declining since 2007. Clinical diagnosis of preterm labor is made if there are regular contractions and concomitant cervical change. Less than 10% of women with a clinical diagnosis of preterm labor will deliver within seven days of initial presentation. Women with a history of spontaneous preterm delivery are 1...

INTRODUCTION: Postoperative pain is a major cause of fear and anxiety in hospitalized patients and so if patients remain pain-free during this period, they can cooperate with the circumstances well, leading to early recovery. Over the last two decades, there has been considerable revival of interest in the use of regional anesthesia techniques for surgery and pain management. As very few studies have been conducted using ropivacaine with dexmedetomidine and magnesium sulfate (MgSO4) as adjuvants, the present study was undertaken with primary aims to compare the hemodynamic stability, onset and duration of sensory and motor block and with secondary aims of the postoperative analgesic effect of dexmedetomidine and MgSO4 along with ropivacaine...

Inulin-type fructans are polymers of fructose molecules and are known for their capacity to enhance absorption of calcium and magnesium, to modulate gut microbiota and energy metabolism, and to improve glycemia. We evaluated and compared the effects of Chicory inulin "Synergy 1®" and inulin from Mexican agave "Metlin®" in two experimental models of colon cancer and bone calcium metabolism in mice and rats. Inulins inhibited the development of dextran sulfate sodium-induced colitis and colon cancer in mice; these fructans reduced the concentration of tumor necrosis factor alpha and prevented the formation of intestinal polyps, villous atrophy, and lymphoid hyperplasia...

Myasthenia gravis (MG) is a rare autoimmune disease that leads to progressive muscle weakness and is common during female reproductive years. The myasthenic mother and her newborn must be observed carefully, as complications during all stages of pregnancy and the puerperium may arise suddenly. Preeclampsia is a common obstetrical condition for which magnesium sulfate is used for seizure prophylaxis. However, magnesium sulfate is strongly contraindicated in MG as it impairs already slowed nerve-muscle connections...
