The small intestinal bacterial flora of 15 patients with chronic renal insufficiency was compared with that of subjects with blind loop syndrome. 9 patients were on regular hemodialysis with high protein intake and 6 (serum creatinine 7.5 to 12.5 mg/dl) were maintained on low protein diet. The chronic renal patients harbored a greatly increased microbial flora of both anaerobes and aerobes in the duodenum and jejunum, quantitatively comparable to those in blind loop subjects. The composition did not differ significantly in the two groups. Some organisms may have the potential to metabolize substrates which reach the intestinal lumen from the diet and bile, and perhaps to generate toxic metabolites that could contribute to uremic toxicity or malabsorption.

A prospective audit was performed on 100 consecutive patients who underwent Pipelle endometrial sampling in a general outpatient clinic setting. The indications for sampling were abnormal menstrual bleeding (AMB, 65), intermenstrual or postcoital bleeding (IMB/PCB, 7), postmenopausal bleeding (PMB, 28). An insufficient sample was obtained in 33 women: (AMB 14, 21.5%); IMB/PCB, (0); PMB 19,68%). In 3 women the Pipelle was unable to be introduced through the cervix; in the remainder an insufficient sample for histological diagnosis was obtained. Registrars and resident doctors were more likely to sample insufficiently. In the AMB group all but 1 woman with an insufficient sample had further investigations or treatment but 7 of 19 (37%) of PMB patients had no further investigations. Where definitive histology was available, endometrial polyps or submucous fibroids were found in half of the cases with an inadequate Pipelle sample. Pipelle sampling detected only 1 of the 2 cases of endometrial cancer in this study.

SummaryBreast cancer-related lymphoedema (BCRL) is a debilitating, distressing condition affecting approximately one in five breast cancer survivors (Clark B, Sitzia J, Harlow W. Incidence and risk of arm oedema following treatment for breast cancer: a three-year follow-up study. QJM 2005;98:343-8). The evidence-base for breast cancer-related lymphoedema risk reduction advice is scant and contradictory, with most studies in the area limited by small numbers, retrospective design and other methodological inadequacies. Current advice has the capacity to profoundly alter quality of life following treatment for breast cancer. Health professionals should review the risk reduction advice they provide to reflect the current understanding of aetiology and risk factors. Further research is required to provide more evidence for the content, to identify optimal methods of precautionary education delivery and to determine the effect of the advice on the patient's quality of life and perception of recovery.

A random population-based study using a structured telephone questionnaire was undertaken to determine the frequency, duration and prevalence of waking cervical spine pain and stiffness, headache, and aching between the scapulae or in the arm and their relationship to age and gender. Seventy-six per cent of households contacted completed the questionnaire, yielding a total of 812 questionnaires. Subjects most commonly reported waking with scapular or arm pain (27%) followed by headache (19%), cervical pain (18%) and cervical stiffness (17%). The majority of subjects reported that symptoms lasted for more than an hour on one or two occasions during the week. Subjects who reported the presence of one type of waking symptom were significantly more likely to report other waking symptoms. Females were significantly more likely to wake with a headache than males (OR 2.5, 95% CI 1.6 to 4.0), while all subjects aged over 60 years were significantly less likely to wake with a headache than subjects in other age groups (OR 0.6, 95% CI 0.4 to 1.0). Females exhibited a decline in waking cervical pain, stiffness and headache with increasing age. In contrast, males exhibited a peak prevalence of waking cervical pain, stiffness and headache in the 40 to 59 year age group. The prevalence of waking with aching between the scapulae or in the arm behaved differently from the other symptom groups in both genders.
