Symptomatic uncomplicated diverticular disease of the colon (SUDD) is generally managed by gastroenterologists rather than General Practitioners (GPs). The aim of this study was to assess the efficacy of the treatment of SUDD with rifaximin, a non-absorbable antibiotic, in a primary care setting by GPs.This retrospective, observational study investigated the use of rifaximin at a dose of 400 mg b.i.d. for 5, 7 or 10 days monthly, up to 3 months. The symptoms were reported by the patients using a visual analogic scale (VAS) of 0-10.286 SUDD patients were enrolled (44.4% of men, average age 70.92±10.98). Respectively, 15 (5.2%) patients received the treatment for 5 days, 205 (71.7%) for 7 days and 66 (23.1%) for 10 days. After three months, a significant reduction of VAS score was observed in almost all symptoms assessed: 135 (47.2%) patients reported no abdominal pain (p0.001) and 23 (8.1%) reported no symptom. Adverse events related to the treatment were recorded in 3 (1.04%) patients, all of them mild and not requiring interruption of the treatment. Acute diverticulitis occurred in 9 (3.1%) patients, but only 2 of them [0.7% (n=2)] underwent surgery due to complicated diverticulitis. Analysis within the different treatment groups (5, 7 and 10 days) shows that rifaximin treatment is effective in reducing the severity of symptoms in almost all groups except for the constipation in the 5-day group.Rifaximin can be effectively used by GPs in real-life for the management of SUDD.

Background Estrogen increases dramatically during pregnancy but quickly drops below prepregnancy levels at birth and remains suppressed during the postpartum period. Clinical and rodent work suggests that this postpartum drop in estrogen results in an estrogen withdrawal state that is related to changes in affect, mood, and behavior. How estrogen withdrawal affects oxytocin (OT) neurocircuitry has not been examined. Methods We used a hormone-simulated pseudopregnancy followed by estrogen withdrawal in Syrian hamsters, a first for this species. Ovariectomized females were given daily injections to approximate hormone levels during gestation and then withdrawn from estrogen to simulate postpartum estrogen withdrawal. These hamsters were tested for behavioral assays of anxiety and anhedonia during estrogen withdrawal. Neuroplasticity in OT-producing neurons in the paraventricular nucleus of the hypothalamus and its efferent targets was measured. Results Estrogen-withdrawn females had increased anxiety-like behaviors in the elevated plus maze and open field tests but did not differ from control females in sucrose preference. Furthermore, estrogen-withdrawn females had more OT-immunoreactive cells and OT messenger RNA in the paraventricular nucleus of the hypothalamus and an increase in OT receptor density in the dorsal raphe nucleus. Finally, blocking OT receptors in the dorsal raphe nucleus during estrogen withdrawal prevented the high-anxiety behavioral phenotype in estrogen-withdrawn females. Conclusions Estrogen withdrawal induces OT neuroplasticity in the paraventricular nucleus of the hypothalamus and dorsal raphe nucleus to increase anxiety-like behavior during the postpartum period. More broadly, these experiments suggest Syrian hamsters as a novel organism in which to model the effects of postpartum estrogen withdrawal on the brain and anxiety-like behavior.

Haemoglobin glycosilate was evaluated using the bio-rad method in 129 diabetics during their periodic visits to outpatient departments. A significant correlation between this test and metabolic compensation was revealed in confirmation of results reported in most research so far carried out. The advantages of using this test in outpatients departments is also emphasised.

Laurell's two-dimensional technique was employed in a study of the immunoelectrophoretic behaviour of caeruloplasmin in 10 major burn cases. A double peak was noted throughout the entire course. The second peak disappeared on recovery whereas it persisted and was well marked in the case of those who died. It is suggested that this pattern reflects the severe liver damage sustained by burn patients.
