Loperamide was used to provide a source of opioid-induced constipation in healthy volunteers. Each volunteer took a sequence of three dose levels of loperamide. One of three laxatives was used to counterbalance the effect of loperamide and restore bowel function to what the individual considered normal at each stage before the dose of loperamide was increased. Lactulose, senna, and codanthrusate were selected as examples of a softening, a stimulant, and a combination laxative, respectively. Outcome measures were the doses of laxative used, stool form and frequency, ease of defecation, a rating scale of subjective bowel function, and the occurrence of adverse effects. Each laxative was taken by ten volunteers, and all proved capable of maintaining normal bowel function. A combination of stimulant and softening laxatives was most likely to maintain normal bowel function at the lowest dose and least adverse effects. The mean final dose of lactulose was excessive for use in ill patients. Senna was associated with significantly more adverse effects than the other laxatives, mainly abdominal pain (P < 0.001). This model of constipation may provide a standardized means of assaying the clinical effectiveness of oral laxatives.

Forty-six patients were randomized to receive either 45 or 90-ml oral sodium phosphate (NaP) (Fleet Phospho-Soda), or X-Prep (a Senna preparation) before elective colonoscopy to compare the quality of colon cleansing, ease of preparation, and gastrointestinal intolerance. Before colonoscopy, one of us administered a questionnaire to the patient to assess how well the preparation was tolerated (scale from 1 to 5: 1 = easy, to 5 = unable to finish) and about the presence of four symptoms:abdominal pain, nausea, vomiting, and dizziness. The quality of colon cleansing was graded by two gastroenterologists (1 = excellent, 2 = good, 3 = fair, 4 = poor), who were unaware of how the patient was prepared or tolerated the preparation. The overall quality of bowel preparation with 90-ml oral NaP was better than with X-Prep and 45-ml NaP (p < 0.01). Patients found preparation with NaP to be easier than X-Prep (p < 0.002). No difference was seen in the incidence of abdominal pain, nausea, vomiting or dizziness. In the 90-ml NaP group, a significant rise in sodium and chloride occurred. However, increments were not greater than 5%. Hyperphosphatemia was noted with NaP, but was transient, and no concomitant decrease in calcium was seen. We conclude that, in the groups of patients studied, 90-ml NaP is a safe colonic cleansing agent that is better tolerated and more effective than others.

Fever of unknown origin (FUO) remains to be a challenge despite advancement in diagnostic technologies and procedures. FUO is considered when fever presents intermittently without an explanation. It has been linked to various etiologies, which makes it difficult to diagnose. We present the case of 18-month-old female with recurrent fever, splenomegaly, abdominal pain, and constipation. The workup for her symptoms revealed wandering spleen. Wandering spleen is a result from excessive laxity or absence of splenic ligaments. The patient underwent splenectomy and was advised to continue on Senna, Miralax, and high fiber diet. Her mother reported that the fever is no longer present and there is marked improvement in her constipation and abdominal pain after splenectomy.
