The results of surgical treatment in 100 patients with intrahepatic gallstones are reported including follow-up on 61 patients who survived more than three years. Nine patients died in the follow-up period, and of the remainder, 44 showed complete rehabilitation (72%). The results of follow-up examinations were best shown by improvement in the tests of hepatic function when compared with the values at the time of discharge. However, in those patients with a long duration of illness, or with residual stones or with impairment of liver function, many claimed persistent complaints and showed abnormal late values of hepatic function. Patients with intrahepatic gallstones are best managed: 1) removal of all gallstones as thoroughly as possible, 2) additional procedures to eliminate bile stasis and permit residual stones to enter the intestinal tract and 3) irrigation of the biliary ducts to remove remaining stones.

Altered NO levels in the PVN affected the frequency of reflexive erections, but not the mount rate. These studies contrast with previous observations of the effects of altered NO levels in the MPOA, and support the hypothesis that physiological specificity in the actions of NO on discrete brain nuclei may have important implications to erectile physiology and dysfunction.

We report herein the case of a patient in whom metastatic colon carcinoma was found within an inguinal hernia sac. According to Lejar's classification, colon carcinomas within inguinal hernias are categorized as intrasaccular- and saccular-type tumors. In our patient, asymptomatic transverse colon carcinoma was the primary lesion, and to the best of our knowledge, this is only the fourth case of such a saccular-type tumor to be reported in the literature. To date, 21 cases of intrasaccular tumors have been reported, and saccular-type tumors are considered to be an even rarer entity, unless the patients have obvious ascites, indicating peritonitis carcinomatosa. Histologic examination of the hernia sac is recommended for male patients of advanced age with an inguinal hernia, especially those who have previously undergone surgery for colorectal carcinoma.

ABSTRACT:We studied the effects of castration and testosterone (T) replacement on intracavernous pressure (ICP) elicited with electrical stimulation of the medial preoptic area (MPOA) and cavernous nerve (CN) in male rats. We measured the ICP during electrical stimulation of the MPOA and CN in castrated male rats with and without testosterone replacement. The experimental group consisted of 20-week-old male rats at 2 weeks (n 5 8), 4 weeks (n 5 8) and 8 weeks (n 5 8) after castration, and at 8 weeks after castration with T replacement (n 5 4). Intact 20-week-old rats (n 5 8) served as controls. The erectile response was expressed as the ICP/ blood pressure (BP) ratio. The ICP/BP ratios during CN stimulation of the animals at 2, 4, and 8 weeks after castration were significantly lower than those of the intact animals. However, the erectile responses were not eliminated. In contrast to these peripherally evoked responses, erectile responses elicited by electrical stimulation of the MPOA were eliminated following castration. After testosterone replacement, both erectile responses were restored. Testosterone plays important roles in both the central and peripheral neural pathways for the maintenance and restoration of erectile capacity. The central control of erection shows more extensive changes following testosterone replacement than the peripheral control.
