RESUMO
BACKGROUND: To evaluate the effect of duloxetine when added to a multimodal analgesia regimen on posthemorrhoidectomy pain, opioid consumption, and side effects. METHODS: Prospective, randomized, double-blind placebo-controlled trial. This study included 62 patients who underwent hemorrhoidectomy. The patients were randomly assigned to receive oral duloxetine 60 mg or placebo 2 h before and 24 h after surgery. The primary outcomes were pain intensity - measured on an 11-point visual analog pain scale - and cumulative morphine consumption at 12, 24, and 48 postoperative hours. RESULTS: Fifty-two patients completed the study (25 in the duloxetine group and 27 in the placebo group). Pain scores did not differ between duloxetine and placebo: 4.5; 3.0 - 7.0 vs. 5.0; 3.5 - 7.0, p = 0.68 at 12 h, 3.0; 2.0 - 5.0 vs. 3.0; 2.0 - 5.0, p = 0.56 at 24 h, and 2.5; 1.75 - 3.75 vs. 1.5; 0.5 - 3, p = 0.08 at 48 h. Further, cumulative morphine consumption did not differ between the duloxetine and placebo groups: 4; 1.25 - 10.75 mg vs. 7; 1.0 - 12.0 mg, p = 0.68 at 12 h, 9.5; 2.0 - 17.5 mg vs. 8.0; 4.0 - 18.0 mg; p = 0.80 at 24 h, and 11.0; 2.0 - 27.0 mg vs. 10; 4.0 - 24.0 mg, p = 0.78 at 48 h. Side effects did not differ between the groups. CONCLUSIONS: Compared with placebo, duloxetine did not decrease pain intensity or morphine consumption during the first 48 h postoperatively. TRIAL REGISTRATION: The study was retrospectively registered on the Brazilian Clinical Trials Registry (identifier: RBR-9pdgms, registration date: 08/10/2020).

PURPOSE: To investigate the impact of cafeteria diet on ghrelin expression in rectal tissue and identify the morphologic cell type. METHODS: Twenty-four male Wistar rats were divided into four subgroups of six animals each: RC1 (rat chow 1) and CAF1 (cafeteria diet 1) for a period of 30 days; RC2 (rat chow 2) and CAF2 (cafeteria diet 2) for a period of 60 days. The animal and rectal weight, the number and the type of immunoreactive ghrelin cells were recorded and compared between the subgroups. The statistical study was established by ANOVA and Student's t test. RESULTS: There was no difference in the total of immunoreactive cells (p=0.685) between the subgroups nor between weight and presence or absence of ghrelin expression (p=0.993). All the immunoreactive cells identified were closed-type. CONCLUSION: The cafeteria diet did not have influence on the amount of immunoreactive rectal cells of ghrelin and only one type (closed-type) of immunoreactive cells was expressed in the rectum.

Although unusual, foreign body ingestion occurs in dentistry and may result in serious complications, such as intestinal perforation. The presence of the foreign body should be confirmed with the use of radiographs. The exam will allow the correct diagnosis and the treatment to be conducted according to the specific situation of the object in the gastrointestinal (GI) tract. The orientation of the patient as well as the awareness of the patient's medical history are key factors in preventing serious complications. Generally, instruments that enter the GI tract pass asymptomatically and atraumatically within 4 days to 2 weeks. Sometimes, a surgical approach is necessary to remove the instrument when there is bleeding, obstruction, or impaction in the GI tract. Thus, a correct diagnosis is vital to avoid unnecessary surgical interventions. The aim of this article is to report an accidental ingestion of a screwdriver by a patient who had previously undergone a hemi-mandibulectomy and its medical resolution.
