Comparison Between Intravenous and Intramuscular Octreotide in the Management of Heyde's Syndrome.

Heyde's syndrome is defined as a triad of aortic stenosis, anemia due to angiodysplasia-related bleeding, and von Willebrand syndrome type 2A. It is a rare disease and a diagnostic challenge. Treatment modalities include symptomatic management, blood transfusions, aortic valve replacement, and medications such as octreotide. Here, we report the case of a patient who was resistant to symptomatic management, aortic valve replacement, as well as intravenous octreotide.

Incidental massive lower gastrointestinal hemorrhage caused by a rectal Dieulafoy's lesion.

A Dieulafoy's lesion is a rare cause of massive gastrointestinal (GI) bleeding. It represents an abnormally dilated submucosal artery that erodes the overlying epithelium in the absence of a primary ulcer. These lesions are usually located in the stomach, nevertheless, they have been found in all areas of the GI tract, including the oesophagus, duodenum and colon. Bleeding episodes are often self-limited, although bleeding can be recurrent and profuse. The case describes a 50-year-old woman who developed haemorrhagic shock secondary to a rectal Dieulafoy's lesion and discusses the diagnostic and therapeutic approaches.

A case of cannabinoid hyperemesis syndrome with Heliobacter pylori and preeclampsia during pregnancy.

BACKGROUND: The condition termed cannabinoid hyperemesis syndrome (CHS) was characterized a decade ago by Allen et al. and includes cyclic episodes of nausea and vomiting and the learned behavior of hot bathing in individuals with chronic cannabis abuse. During pregnancy, the differential diagnosis of this syndrome is challenging, since it can be masked by typical symptoms of early pregnancy or by hyperemesis gravidarum, a complication of early pregnancy associated with excessive nausea and vomiting. CASE DESCRIPTION: The authors herein describe the case of a 21-year-old primigravida patient diagnosed with hyperemesis gravidarum at 6 weeks of gestation and with preeclampsia at 35 weeks. At 30 weeks of gestation, a drug screen was performed that was positive for cannabis; therefore, a diagnosis of CHS was made. After labor induction, the patient delivered an infant who developed normally and had a negative drug test of the umbilical cord blood. Esophagogastroduodenoscopy was performed 9 days post delivery, with biopsies taken of the duodenal, gastric, and esophageal tissues. Moderate chronic gastritis with lymphoid aggregates and slight acute inflammation were noticed, whereas no malignancy, dysplasia, or goblet cell metaplasia was detected. A number of Helicobacter-like organisms were identified by H. pylori immunostaining. CONCLUSION: Presented here is the first case reporting an association of chronic cannabis use with H. pylori colonization and preeclampsia in pregnancy, which brings to light the possible involvement of a cannabinoid-related pathway in the link between pregnancy-specific complications and bacterial colonization.

Disseminated Coccidioidomycosis Presenting as Carcinomatosis Peritonei and Intestinal Coccidioidomycosis in a Patient with HIV.

Coccidioidomycosis (CM) is a fungal infection endemic in southwestern regions of the United States, northwestern regions of Mexico, and some areas of Brazil and Argentina. Clinical presentation varies depending on the extent of the infection and the immune status of the host. The most common presentation ranges from flu-like symptoms to self-limiting pneumonia. Extrapulmonary presentations are uncommon and may involve the meninges, skin, and bone. Gastrointestinal and peritoneal involvement is extremely rare. Here we report a case of disseminated CM presenting as carcinomatosis peritonei as an AIDS-defining illness in a young male.
