Selective 5-HT7 receptor agonists LP 44 and LP 211 elicit an analgesic effect on formalin-induced orofacial pain in mice

The most recently identified serotonin (5-HT) receptor is the 5-HT7 receptor. The antinociceptive effects of a 5-HT7 receptor agonist have been shown in neuropathic and inflammatory animal models of pain. A recent study demonstrated the functional expression of 5-HT7 receptors in the substantia gelatinosa (SG) of the trigeminalsubnucleus caudalis, which receives and processes orofacial nociceptive inputs. Objective To investigate the antinociceptive effects of pharmacological activation of 5-HT7 receptors on orofacial pain in mice. Material and Methods Nociception was evaluated by using an orofacial formalin test in male Balb-C mice. Selective 5-HT7 receptor agonists, LP 44 and LP 211 (1, 5, and 10 mg/kg), were given intraperitoneally 30 min prior to a formalin injection. A bolus of 10 µl of 4% subcutaneous formalin was injected into the upper lip of mice and facial grooming behaviors were monitored. The behavioral responses consisted of two distinct periods, the early phase corresponding to acute pain (Phase I: 0–12 min) and the late phase (Phase II: 12–30 min). Results LP 44 and LP 211 (1, 5, and 10 mg/kg) produced an analgesic effect with reductions in face rubbing time in both Phase I and Phase II of the formalin test. Conclusion Our results suggest that 5-HT7 receptor agonists may be promising analgesic drugs in the treatment of orofacial pain

Role of Self Expandable Stents in Management of Colorectal Cancers

Acute malignant colorectal obstruction is a complication of colorectal cancer that can occur in 7%-29% of patients. Self-expanding metallic stent placement for malignant colorectal obstruction has gained popularity as a safe and effective procedure for relieving obstruction. This technique can be used in the palliation of malignant colorectal obstruction, as a bridge to elective surgery for resectable colorectal cancers, palliation of extracolonic malignant obstruction, and for nonmalignant etiologies such as anastomotic strictures, Crohn's disease, radiation therapy, and diverticular diseases. Self-expanding metallic stent has its own advantages and disadvant-ages over the surgery in these indications. During the insertion of the self-expanding metallic stent, and in the follow-up, short term and long term morbidities should be kept in mind. The most important complications of the stents are perforation, stent obstruction, stent migration, and bleeding. Additionally, given the high risk of perforation, if a patient is treated or being considered fortreatmentwith antiangiogenic agents such as bevacizumab, it is not recommended to use self-expanding metallic stent as a palliative treatment for obstruction. Therefore, there is a need for careful clinical evaluation for each patient who is a candidate for this procedure. The purpose of this review was to evaluate self-expanding metallic stent in the management of the obstruction of the colon due to the colorectal and extracolonic obstruction.Wo

Management Of A Pregnancy With A Solid Pseudopapillary Neoplasm Of The Pancreas

A 26-year-old primigravid patient, at 35 weeks and 2 days of gestation, was referred to Hacettepe University Hospital for pancreatic mass, giant cervical myoma, maternal systemic lupus erythematosus, thrombocytopenia, and onset of preterm labor. At 36 weeks and 1 day of gestation (6 days after admission to the hospital), regular uterine contractions started and cervical dilatation with effacement was observed. Because of breech presentation and giant cervical myoma, a cesarean section was performed on the primigravid patient under general anesthesia. Four months after the birth, subtotal pancreatectomy, partial gastrectomy, duodenectomy, cholecystectomy, and omentectomy (Whipple procedure) were performed. The pathologic diagnosis was of a solid pseudopapillary neoplasm of the pancreas; the patient was discharged from hospital after ten days.PubMe

Gastric Volvulus: A Rare Diagnosis Of Abdominal Pain

Gastric volvulus (GV) is a rare but life-threatening condition in case of delay in diagnosis and treatment. Herein, we presented a case of GV due to Morgagni hernia presenting to the emergency department with complaints of abdominal pain and distention. A 59-year-old male patient was admitted to the emergency department with abdominal pain and distension, nausea and vomiting. His past medical history included coronary artery disease, hypertension, multiple sclerosis and left diaphragmatic hernia. On initial examination, pulse rate was 119/min and other vital signs were normal. Abdominal examination revealed epigastric tenderness. Posteroanterior chest X-ray showed an air bubble in the left hemithorax. Thoracoabdominal CT was performed for differential diagnosis. Department of Emergency Radiology reported a mesenteroaxial gastric volvulus at the superior gastro-esophageal junction with a Morgagni hernia including left hemidiaphragmatic defect with herniation of the gastric corpus, first part of the duodenum and transverse colon. Following placement of the nasogastric tube, 1300 mL gastric secretion was drained and abdominal distention was relieved. Patient was referred to the operating room. Morgagni hernia and the diaphragm defect were repaired. During follow-up in general surgery ward, a sudden cardiac arrest developed on the 5th day and he died. If a patient presents to the emergency departmen with abdominal pain and distention, GV should be considered in the differential diagnosis, although rare.Wo

Recommendations for Intra-abdominal Infections "Consensus Report"

WOS: 000407294300008Guidelines include recommendations of experts from various specialties within a topic in consideration of data specific to each country. However, to date there has not been a guideline standardizing the nomenclature and offering recommendations for intra-abdominal infections (IAIs) in Turkey. This is mainly due to the paucity of laboratory studies regarding the clinical diagnosis and treatment of IAIs or the sensitivity of microorganisms isolated from patients with IAIs. However, due to the diversification of host characteristics and advancements in technological treatment methods, it has become imperative to "speak a common language". For this purpose, meetings were formed under the leadership of the Infectious Diseases and Clinical Microbiology Specialty Society of Turkey (EKMUD) consisting of 15 experts in IAIs from the Turkish Surgical Association, Turkish Society of Colon, Turkish Hernia Society, Turkish Society of Hepato-Pancreato-Biliary Surgery, and the Turkish Society of Hospital Infections and Control; and relevant studies were analyzed.. Ultimately, the suggestions for adults found in this consensus report were prepared using available data from Turkey, and referring predominantly to the 2010 guidelines for diagnosing and managing complicated IAIs in adults and children by the Infectious Diseases Society of America and the Surgical Infection Society. Recommendations are conducted in two sections from the initial evaluation of patients for diagnosis to treatment approach for IAI. This Consensus Report was presented in Turkey EKMUD 2016 Congress/Antalya and subsequently opened for any suggestions in Turkey EKMUD and Turkish Surgical Association official web sites for a month. The manuscript was updated according to the suggestions
