Toothbrushes are the most common cause of foreign body injury to the oral cavity in children, but complete impalement by a toothbrush is an extremely rare occurrence and has not been reported previously. This report describes a 28-month girl who fell from a one-meter ledge while brushing her teeth. Her toothbrush penetrated the oral cavity and could not be removed, so she was rushed to the hospital with the toothbrush in place. Contrast-enhanced computed tomography showed penetration of the toothbrush from the oral cavity into and through the right posterior neck at the level of the bifurcation of the common carotid artery...

REVIEW
Srinivas R Rami Reddy, Mitchell S Cappell
PURPOSE OF REVIEW: This study aimed to systematically review small bowel obstruction (SBO), focusing on recent changes in diagnosis/therapy. RECENT FINDINGS: SBO incidence is about 350,000/annum in the USA. Etiologies include adhesions (65%), hernias (10%), neoplasms (5%), Crohn's disease (5%), and other (15%). Bowel dilatation occurs proximal to obstruction primarily from swallowed air and secondarily from intraluminal fluid accumulation. Dilatation increases mural tension, decreases mucosal perfusion, causes bacterial proliferation, and decreases mural tensile strength that increases bowel perforation risks...

BACKGROUND: Acute appendicitis, especially if perforated at presentation, is often complicated by postoperative abscess formation. The detection of a postoperative abscess relies primarily on imaging. This has traditionally been done with contrast-enhanced computed tomography. Non-contrast magnetic resonance imaging (MRI) has the potential to accurately detect intra-abdominal abscesses, especially with the use of diffusion-weighted imaging (DWI). OBJECTIVE: To evaluate our single-center experience with a rapid non-contrast MRI protocol evaluating post-appendectomy abscesses in children with persistent postsurgical symptoms...

BACKGROUND: Patients with diverticulitis are predisposed to hepatic abscesses via seeding through the portal circulation. Hepatic abscesses are well-documented sequelae of diverticulitis, however instances of progression to hepato-bronchial fistulization are rare. We present a case of diverticulitis associated with hepatic abscess leading to hepato-bronchial fistulization, which represents a novel disease course not yet reported in the literature. CASE PRESENTATION: A 61-year-old Caucasian man presented with a history of unintentional weight loss and dyspnea both at rest and with exertion...

BACKGROUND: After gastrectomy or esophagectomy, esophagogastrostomy and esophagojejunostomy are commonly used for reconstruction. Water-soluble contrast swallow is often used as a routine screening to exclude anastomotic leakage during the first postoperative week. In this retrospective study, the sensitivity and specificity of oral water-soluble contrast swallow for the detection of anastomotic leakage and its clinical symptoms were analysed. MATERIAL/METHODS: Records of 104 consecutive total gastrectomies and distal esophagectomies were analysed...

AIM: Same day CT colonography (CTC) for incomplete colonoscopy should be considered to avoid the need for further bowel preparation. Oral administration of contrast is essential for optimal colonic analysis of the CTC. Our aim was to determine the optimal time for giving contrast to people who underwent same day CTC after failed colonoscopy. METHODS: Data was extracted from the Trust database to identify the number of CTC referrals following failed or incomplete colonoscopy within the last 5 years, and the reason for their referral...

BACKGROUND: Gastric leak (GL) is one of the main early-onset postoperative complications of sleeve gastrectomy (SG). Many institutions perform routine upper gastrointestinal (UGI) contrast studies within 24 hours of surgery, looking for GL or gastric stenosis and to determine the need for urgent re-exploration, but this examination delays oral feeding, can cause side effects and is responsible for systematic and probably unnecessary irradiation of the patient. OBJECTIVE: Determine the efficacy of routine UGI contrast studies to predict postoperative complications after SG in a large population...

Abdominal actinomycosis is a rare infectious disease, caused by gram positive anaerobic bacteria, that may appear as an abdominal mass and/or abscess (Wagenlehner et al. 2003). This paper presents an unusual case of a hemodynamically stable 80-year-old man who presented to the emergency department with 4 weeks of worsening abdominal pain and swelling. He also complains of a 20-bound weight loss in 2 months. A large tender palpable mass in the right upper quadrant was noted on physical exam. Laboratory studies showed a normal white blood cell count, slightly decreased hemoglobin and hematocrit, and mildly elevated total bilirubin and alkaline phosphatase...

Teratomas are benign tumours containing cells from ectodermal, mesodermal and endodermal layers with an incidence of about 1 in every 4,000 births. Their commonest site is sacro-coccygeal region, followed by anterior mediastinum. The incidence of teratomas localised to the head and neck region is around 2-9% of all cases. Epignathus is a rare congenital oropharyngeal teratoma originating from the base of the skull. Here we present a rare case of oropharyngeal teratoma in a neonate who was referred to our institute with an ill-defined oral mass protruding through a cleft in the hard palate...

One of the most important prognostic factors in oral squamous cell carcinoma (OSCC) is the presence of lymph node metastasis. Therefore, the early detection of late-presenting cervical lymph node metastasis is important. Although many studies have assessed diagnostic modalities for detecting metastatic cervical lymph nodes, no study has evaluated the process, especially first signs, for detecting late-presenting cervical lymph node metastasis. A retrospective analysis comparing methods for detecting the first signs of late-presenting lymph node metastasis was performed...

Deep abdominal vein thrombosis is extremely rare among thrombotic events secondary to the use of contraceptives. A case to illustrate the clinical utility of ethno-specific pharmacogenetic testing in warfarin management of a Hispanic patient is reported. A 37-year-old Hispanic Puerto Rican, non-gravid female with past medical history of abnormal uterine bleeding on hormonal contraceptive therapy was evaluated for abdominal pain. Physical exam was remarkable for unspecific diffuse abdominal tenderness, and general initial laboratory results-including coagulation parameters-were unremarkable...
