Preoperative Nyhus classification of inguinal hernias and type-related individual hernia repair. A case for diagnostic laparoscopy.

The goal of this prospective study was to determine the clinical value (sensitivity and specificity) of preoperative hernia classification (Nyhus classification) using three distinct methods: clinical examination, Doppler ultrasonography, and diagnostic laparoscopy. Thirty patients with 35 suspected groin hernias were included. Definitive hernia classification was achieved by laparoscopic peritoneal incision and dissection of the inguinal floor.

Effect of ethanol and fructose on liver metabolism: a dynamic 31Phosphorus magnetic resonance spectroscopy study in normal volunteers.

In vivo 31Phosphorus magnetic resonance spectroscopy (31P-MRS) permits evaluation of dynamic changes of individual phosphorus-containing metabolites in the liver parenchyma, such as phosphomonoester (PME), adenosine triphosphate, and inorganic phosphate (Pi). Intravenous fructose load alters phosphorus metabolites and allows assessment of liver function by 31P-MRS. 31P-MRS data obtained in alcoholic liver disease are however inconclusive.

Long-term results of arthroscopic meniscal repair. An analysis of isolated tears.

From 1984 through 1986 we performed 54 arthroscopic meniscal repairs on patients with anterior cruciate ligament-stable knees. We evaluated the repair results of 52 of these patients at an average followup of 7.5 years.
