Gastric volvulus is an abnormal, potentially life-threatening, torsion of the stomach. The presence of complications such as hemoperitoneum increases the diagnostic urgency; however it can also mask the presentation of gastric volvulus. We encountered a 66-year-old female who presented with symptomatic gastric outlet obstruction and was found to have hemoperitoneum and splenic avulsion on imaging. In our case, hemoperitoneum was a clinical red herring as initial imaging concentrated on the presence of hemoperitoneum and was nondiagnostic of gastric volvulus. Interestingly, our patient experienced complete resolution of her presenting symptomatology following placement of a nasogastric tube. Furthermore, endoscopic evaluation revealed no overt pathology to explain outlet obstruction. In light of these findings, gastric torsion was strongly suspected. A repeat CT scan was confirmatory, elucidated reduction of the stomach to its anatomic position, retroactively diagnosing a gastric volvulus. This case is unusual in its presentation and setting. The patient presented with two rare complications of gastric volvulus, hemoperitoneum and splenic avulsion. Additionally, ten years prior to this presentation the patient had a temporary gastrostomy tube. Gastropexy with a gastrostomy is the treatment for gastric volvulus and should have been preventative of her presentation with torsion. Furthermore, the gastric volvulus was not initially recognized radiographically due to the presence of masking radiographic findings. This case serves to highlight the utility of clinical acumen and maintain a high index of suspicion for gastric volvulus in all cases presenting with Borchardt's triad.

BACKGROUND:Dual antiplatelet (Plt) therapy with aspirin and clopidogrel is recommended for up to 1 year following acute coronary syndrome. Many of these cardiac patients are also on anithrombotic therapy like warfarin. Lower gastrointestinal bleeding (LGIB) is the main adverse event of this treatment. AIMS/OBJECTIVE:The main purpose of this study was to analyze the relationship of dual anti-Plt therapy and the risk of LGIB. METHODS:Patients' electronic charts were reviewed to include a total of 19 variables, which included age, sex, ethnicity, daily use aspirin of any dose, daily use of clopidogrel, use of nonsteroidal anti-inflammatory drugs (NSAIDs) at least twice in the last week prior to admission and the daily use of anticoagulants (warfarin, heparin), and were obtained from history and physical examination reports, lab transcripts and procedural reports. SETTINGS/DESIGN/UNASSIGNED:A retrospective cohort study of the records of 3436 patients admitted to our hospital from January 1, 2009, to December 31, 2011, was evaluated. All the patients included were admitted through the emergency department with complaints of or relating to LGIB. The primary outcome studied was severe LGIB as defined by the requirement of at least two units of packed red blood cells and/or a decrease in the hematocrit of 20% or more or recurrent bleeding after 24 h of clinical stability with additional transfusions required. Other outcomes included surgical intervention. STATISTICAL METHODS/ANALYSIS/UNASSIGNED:-test on continuous variables and Chi-square test on categorical variables were done before carrying out logistic regression analysis. Logistic regression analyses were conducted to measures of association between the variables and LGIB. Logistic regression analysis was not carried for surgical intervention and death because none of the variables was significant from univariate tests. RESULTS:A total of 511 patients were found to have true LGIB. Among these subjects, 61 were shown to be on dual or multiple antithrombotic therapies. Further exploration revealed that while the use of multiple blood thinning agents may, in fact, pose a significant risk to overall LGIB, it did not significantly increase the risk for severe bleeding as outlined above. CONCLUSION/CONCLUSIONS:The use of multiple blood thinning agents does not significantly increase the risk for severe LGIB.

Cocaine and its alkaloid free base "crack-cocaine" have long since been substances of abuse. Drug abuse of cocaine via oral, inhalation, intravenous, and intranasal intake has famously been associated with a number of medical complications. Intestinal ischemia and perforation remain the most common manifestations of cocaine associated gastrointestinal disease and have historically been associated with oral intake of cocaine. Here we find a rare case of two relatively uncommon gastrointestinal complications of hemorrhage and pancreatitis presenting within a single admission in a chronic crack cocaine abuser.

This case report highlights a rare, virulent, aggressive, poorly differentiated, epithelioid fibrosarcoma with numerous rhabdoid cells on the tibial aspect of an 84-year-old woman. Biopsy of the lesions were reviewed at College of Physicians and Surgeons of Columbia University Department of Dermatopathology (New York, New York) and in consultation with the Soft Tissue Pathology Division of the Surgical Pathology Department at Columbia University as well as the Department of Pathology at the Massachusetts General Hospital Division of Bone and Soft Tissue Pathology. The management of this patient was difficult especially considering her mental status. She had an excellent response to radiation therapy. It is important to be innovative in treatment and to use judgment when assessing unusual entities.

A 15-year-old Caucasian boy with a diagnosis of confluent and reticulated papillomatosis who had received numerous treatments with minimal responses cleared with a 20-week course of 13-cis-retinoic acid and has remained in remission. It is important to consider the use of oral retinoids in the treatment of this stubborn, unsightly, and psychologically upsetting disease.

It is well documented that congenital nevi have a statistical chance of becoming malignant; however, it is unusual to actually follow the progression of such an event. A 48-year-old man photographically documented changes in his own nevus, which was present at birth, over a period of six months. Seeing this evolution in one lesion is interesting. Emphasis must not only be placed upon the importance of early diagnosis, but also on the expeditious removal of suspicious nevi and treatment.
