Women presenting with lower abdominal pain: a missed opportunity for chlamydia screening?

INTRODUCTION: Many young women presenting with lower abdominal pain are referred to general surgeons with possible appendicitis. For some of these patients there will be a gynaecological cause for their pain. There has been a steady increase in the incidence of Chlamydia infections and pelvic inflammatory disease (PID) among the general population. Therefore, are general surgeons considering this as a diagnosis for lower abdominal pain in women? METHODS: One hundred and ninety three women who had been admitted with lower abdominal pain to a single hospital between 1999 and 2001 were identified using computerised records and the notes were examined. One hundred and eighty six women were included in the audit. Investigations and treatments instigated for these patients were then carefully recorded. RESULTS: Seventy-four patients underwent appendicectomy, of which 59 were histologically confirmed. Eighty-nine patients (47.8%) of admissions had no final diagnosis and were not screened for Chlamydia trachomatis. Sexual history was recorded in only 51% of admissions. Vaginal swabs were sent in only 7.3% of admissions. CONCLUSION: Current guidelines for Chlamydia trachomatis screening produced by the Chief Medical Officer (CMO) include screening in women presenting with lower abdominal pain as well as those with post-coital or intermenstrual bleeding. Most women who present with classical symptoms of PID will present to gynaecological specialities for further management. However, a significant number of women presenting atypically will be referred to surgeons to exclude gastrointestinal causes for their lower abdominal pain. These women could and probably should be screened for Chlamydia trachomatis.

Different role of the colonic pouch for low anterior resection and coloanal anastomosis.

BACKGROUND: Functional outcome after sphincter-saving operations can be improved by colonic pouch compared to the straight procedure. However, it is not clear whether the colonic pouch has a different behavior in patients treated by low anterior resection with colorectal (LAR) or coloanal anastomosis (CAA). METHODS: We evaluated the 1-year results of 75 patients who underwent a sphincter-saving operation for rectal carcinoma or villous tumor of the middle or lower third of the rectum: 18 patients underwent coloanal anastomosis (CAA), in 13 patients we performed a coloanal anastomosis with a colonic pouch (PCAA), 20 patients had low anterior resection (LAR) and 24 had LAR with pouch construction (PLAR). The two groups of patients were similar in terms of age and gender. Anorectal function was assessed 12 months after the initial operation by an interview and anorectal manometry. RESULTS: One year after surgery, the daily mean number of defecations was significantly higher in the LAR group than in the other groups (2.0+/-1.5 in CAA group, 2.2+/-1.0 in PCAA, 2.3+/-1.8 in PLAR, 4.1+/-0.7 in LAR; p<0.05). Frequent soiling was observed in all the groups except PLAR. A lower degree of incontinence and a lower frequency of urgency were found in PCAA than in CAA. There were no differences in anal resting pressure and squeeze pressure among the various groups. Greater distensibility and compliance of the neorectum were observed in CAA, PCAA and PLAR compared to LAR, respectively 8.5+/-7.0 ml air/mmHg for CAA, 8.7+/-5.0 ml air/mmHg for PCAA, 6.3+/-4.0 ml air/mmHg for PLAR and 3.1+/-2.7 ml air/mmHg for LAR. A significant inverse linear correlation was present between the mean daily number of defecations and compliance. No difference in sense of incomplete evacuation was observed among the groups of patients. CONCLUSIONS: Colonic J-pouch provides an advantage over straight anastomosis in sphincter-saving operations by reducing the daily number of defecations, and the frequencies of fecal soiling and urgency. The role of the pouch seems to be different in LAR compared to CAA. In fact, in LAR the pouch increases compliance and consequently decreases the daily number of defecations. In CAA, the pouch does not reduce the number of defecations or the compliance, but reduces the frequency of fecal soiling and urgency.

Anal carcinoma occurring in Crohn's disease patients with chronic anal fistula.

This paper reports six patients with perianal Crohn's disease (CD), who developed anal cancer in chronic anal fistulas. Tumors have been often diagnosed at an advanced stage and had a worse prognosis than cancers arising in the general population as tumor symptoms may mimic symptoms of CD, resulting in delay in diagnosis. Patients with perianal CD should undergo a careful surveillance program for ano-rectal carcinoma, including routine biopsy of any suspected lesion. When malignancy is found, an aggressive surgical approach and complementary therapy are mandatory.

Do adolescent vitamin-mineral supplement users have better nutrient intakes than nonusers? Observations from the CATCH tracking study.

OBJECTIVE: Describe whether users of vitamin-mineral supplements differed from nonusers in micronutrient intakes or in nutrition awareness. DESIGN: Cross-sectional, observational study. SUBJECTS: One thousand five hundred thirty-two students now in grade 8, who participated in the Third Child and Adolescent Trial for Cardiovascular Health tracking study and who also provided a single 24-hour dietary recall. STATISTICAL ANALYSES PERFORMED: Mixed-model analysis of covariance was used to ascertain if supplement users had higher vitamin and mineral intakes from food sources, and to examine if supplement users had better nutrition awareness than nonusers. RESULTS: The 24-hour recall showed that 17.6% of the students reported using vitamin-mineral supplements. Users reported a mean of 1.4 supplements, of which 47% were multivitamin or multimineral preparations, 37% were single nutrients, and 16% were combinations. White persons and residents of Minnesota and California were more likely to be supplement users. Users had higher micronutrient intakes from food sources for 16 of the 20 nutrients studied after adjusting for gender, race/ethnicity, site, treatment condition, and within-school variability. Users had higher scores on a health behavior survey for food choice and slightly but not significantly higher nutrition knowledge scores. CONCLUSIONS: Vitamin-mineral supplement use is prevalent among eighth-grade students. Users have higher nutrient intakes from foods, higher total intakes for several micronutrients, higher nutrition awareness, and differ in their demographic characteristics from nonusers.

Straight ileoanal anastomosis with multiple ileal myotomies as an alternative to pelvic pouch.

UNLABELLED: An alternative technique of restorative proctocolectomy, by means of straight ileoanal anastomosis with multiple myotomies (SIAM) of the terminal ileum in 15 patients, nine with familial adenomatous polyposis (FAP) and six with ulcerative colitis (UC) is reported. SURGICAL TECHNIQUE: Eight to ten longitudinal myotomies (3-4 cm long, on three different circumferential sites) were performed on the terminal ileum for a total length of 12-14 cm. CLINICAL RESULTS: At a mean follow up of 44 months (range 3-84 months) from the closure of the ileostomy, daytime continence was achieved in all the patients; stool frequency per 24 hours (+/- SD) was 4.1 +/- 1.8 for FAP patients and 5.8 +/- 1.7 for UC patients; nocturnal defecation was 1.0 +/- 0.5 and 1.2 +/- 0.8 for FAP and UC patients respectively; frequent nocturnal soiling was present in 2/5 of UC patients, and in 3/9 of FAP patients. SIAM failed in one UC patient that was converted to an ileoanal reservoir because of poor functional result. Signs of ileal mucosal inflammation were never observed at endoscopic examination. Histopathological assessment showed no evidence of acute terminal ileitis. MANOMETRIC FINDINGS: A significant postoperative reduction in anal resting pressure was observed after SIAM. Neither the absence of anal inhibitory reflex nor the presence of high pressure waves generated in the terminal ileum during air insufflation were related to the presence of soiling. The closure of the loop ileostomy was followed by an increased capacity and distensibility of the terminal ileum. Values of neorectal compliance were similar in FAP and UC patients although FAP patients were able to reach higher values of maximum tolerated volume and pressure. CONCLUSIONS: 1) SIAM can be an alternative to pelvic pouch in patients who have undergone restorative proctocolectomy when the construction of the pouch is not feasible. 2) The functional result observed after SIAM has been shown to be similar to that observed after pouch construction.
