Management of maxillofacial trauma includes primary care, in which diagnosis and management of dentoalveolar injury play a vital role. Due to the impact sustained during a maxillofacial injury (whether direct or indirect), dentoalveolar injuries can occur, leading to fracture and displacement of teeth and associated alveolar bone into the surrounding soft tissues and associated structures, such as the maxillary sinus, nasal cavity, upper respiratory tract, tracheobronchial tree, or gastrointestinal tract. Undiagnosed displaced teeth may cause complications such as airway obstruction. This paper reports a case of displaced teeth in the nasal cavity and gastrointestinal tract and highlights the management protocol for displaced teeth secondary to maxillofacial trauma.

Aortoenteric fistula is an uncommon important complication of aortic reconstruction with a prosthetic graft. The complication often is difficult to diagnose and is associated with poor prognosis. Aortoenteric fistula could be divided into true aortoenteric fistula and paraprosthetic-enteric fistula. In case of true aortoenteric fistula, an actual communication between the gastrointestinal tract and the aortic lumen is present. So, massive gastrointestinal hemorrhage is the presenting manifestation. In paraprosthetic-enteric fistula, characterized by communication between the gastrointestinal tract and the external surface of synthetic vascular prosthesis without actual fistularization into the vascular lumen, the predominant clinical manifestation were sepsis, fever and anemia. We experienced one case of paraprosthetic-enteric fistula in a 16 years old male after abdominal aortic reconstruction with a prosthetic graft. The interval from the operation to onset of symptoms was 40 months. The initial clinical manifestation was sepsis, fever and anemia without massive gastrointestinal hemorrhage. Surgical treatment consists of complete excision of infected graft, two layers closure of jejunal wall defect and pledgets suture of aortic stump with surrounding health tissue. Anatomic revascularization was not able to be done: because of extensive retroperitoneal inflammation and extraanatomic revascularization did not performed due to adequate distal blood supply through rich collateral circulation. After operation, he complained numbness on left foot on moderate exertion and felt coldness on left leg compared with right leg but not showed skin color change. 43 days after operation, he discharged without gait disturbance except numbness on left foot on moderate exertion.

Ganglioneuroma of the gastrointestinal tract is a rare tumor that consists of ganglion cells, nerve fibers, and supporting cells of the enteric nervous system. Ganglioneuromas are usually associated with genetic disorders such as the multiple endocrine neoplasia syndrome or neurofibromatosis. Ganglioneuromas of the gastrointestinal tract predominantly involve the colon and rectum, and reports about duodenal ganglioneuromas are few. Herein, we report a case of duodenal ganglioneuroma treated with endoscopic resection. A 56-year-old female patient visited our hospital because of a subepithelial tumor in the second portion of the duodenum. She had no remarkable medical or family history and revealed no history of genetic disorders. Endoscopic ultrasonography and abdominal computed tomography revealed a tumor located mainly in the submucosal layer, without any regional lymph node involvement. Endoscopic resection of the lesion was performed, and the pathological examination confirmed a duodenal ganglioneuroma.

Shigella infection usually produces gastrointestinal symptoms but rarely causes urinary tract infection. A 7-year-old girl was admitted for fever, chills, right flank pain, and dysuria. She had no vomiting or diarrhea. There was mild tenderness in her right lower abdomen, and right CVA tenderness was also noted. Acute pyelonephritis was diagnosed by abdominal CT. She showed improvement with intravenous administration of antibiotics. The first urine culture grew $1{\times}10^5$ CFU/mL Shigella dysenteri. Although urinary tract infections due to Shigella species are extremely rare, Shigella species should be considered as a possible cause of pediatric urinary tract infection. We report the first case of urinary tract infection caused by S. dysenteri, which presented as acute pyelonephritis without gastrointestinal symptoms in a child.

Blister beetles produce cantharidin, which is toxic to people and animals. Cantharidin has been believed to be an aphrodisiac and an abortifacient based on its tendency to cause marked irritation to the genitourinary system leading to priapism in men and pelvic congestion in women for many years. Cantharidin was used by oriental traditional medicine for more than 2000 years. Typical signs related to cantharidin ingestion are gastrointestinal tract and urinary tract irritation, endotoxemia, shock and myocardial dysfunction. Cantharidin is a severe irritant to epithelial linings (gastrointestinal tract, urinary tract, and skin) and develop systemic inflammatory response syndrome. We report a case of corrosive esophagogastritis and acute renal failure by ingestion of cantharidin.

Purpose: Laparoscopic proximal gastrectomy with double-tract reconstruction (LPG-DTR) is a function-preserving procedure performed for treating upper early gastric cancer (EGC). However, few studies have compared the outcomes of LPG-DTR with those of laparoscopic total gastrectomy (LTG). This study aimed at comparing the short-term outcomes of LPG-DTR between LTG and upper EGC. Materials and Methods: For upper-third EGC, a multicenter, prospective, randomized trial was performed to compare those who underwent LPG-DTR with those who underwent LTG. Short-term outcomes, including clinicopathologic results, morbidity, mortality, and postoperative courses, were evaluated using a full analysis set based on the intention-to-treat principle and the per-protocol set. Results: Of the patients, 138 who fulfilled the criteria were randomized to each group. One patient in the LPG-DTR group withdrew consent. Sixty-eight patients underwent LPG-DTR and 69 underwent LTG. The operative time (LPG-DTR=219.4 minutes; LTG=201.8 minutes; P=0.085), estimated blood loss (LPG-DTR=76.0 mL; LTG=66.1 mL; P=0.413), and the morbidity rate (LPG-DTR=23.5%; LTG=17.4%; P=0.373) between the groups were not significantly different. No mortality occurred in either of the study groups. Two weeks post operation, the Visick scores for postprandial symptoms, including reflux symptoms, were not significantly different between the groups (P=0.749). Laboratory findings on postoperative day 5 were not significantly different between the groups. Conclusions: The short-term outcomes of LPG-DTR for upper EGC were comparable to those of LTG.

Manometry is a noninvasive diagnostic tool for identifying motility dysfunction of the gastrointestinal tract. Despite the great technical advances in monitoring motility, performance of the study in pediatric patients has several limitations that should be considered during the procedure and interpretation of the test results. This article reviews the clinical applications of conventional esophageal and anorectal manometries in children by describing a technique for performing the test. This review will develop the uniformity required for the methods of performance, the parameters for measurement, and interpretation of test results that could be applied in pediatric clinical practice.

The regional distributions and relative frequencies of the gastrointestinal endocrine cells in the bean goose (Anser fabalis Latham) were investigated by immunohistochemical methods using bovine Sp-1/chromogranin (CG), serotonin, gastrin, cholecystokinin (CCK)-8, somatostatin and glucagon antisera. BCG-immunoreactive cells were widespread throughout the gastrointestinal tract (GIT) with moderated frequencies except for the gizzard and proventriculus which were a few frequencies. Serotonin-immunoreactive cells were detected throughout the GIT except for the proventriculus and gizzard. These cells were observed in the pylorus with rare frequencies but numerous cells were detected in the intestinal tract. Gastrin-immunoreactive cells were restricted to the gizzard, pylorus and duodenum. These cells were most predominant in the pylorus and a few or rare in the gizzard and duodenum, respectively. CCK-8-immunoreactive cells were observed from the gizzard to ileum. The highest frequencies of endocrine cells were observed in the duodenum. These cells were increased from the gizzard to duodenum but thereafter decreased. Somatostatin-immunoreactive cells were detected in the GIT except for the large intestine. In the proventriculus and pylorus, numerous immunoreactive cells were demonstrated but a few cells were present in the other regions. Glucagon cells were observed in the gizzard, pylorus, ileum, colon and rectum with a few or moderated numbers.
