A rare case of sigmoid colon obstruction in patient with ulcerative colitis: role of transabdominal ultrasound-guided biopsy

Introduction

Endometriosis is a common chronic gynaecological disease affecting 10 % of women of reproductive age. Of these 5–12 % may present bowel endometriosis that may be asymptomatic or associated with aspecific symptoms even bowel obstruction.

Case presentation

The case of a 41-year-old woman with history of ulcerative colitis, previous diagnosis of ovarian endometriosis, recurrent abdominal pain not related to the menstrual cycle, with abdominal pain and obstinate constipation for 2 weeks was referred. The patient underwent colonoscopy, transabdominal ultrasound and ultrasound-guided fine-needle biopsy to have a diagnosis.

Discussion

Endometriosis should be considered in the differential diagnosis of every woman of childbearing age who presents with gastrointestinal or abdominal symptoms. As demonstrated in our case and by the burgeoning literature in this field, we believe that the role of transabdominal ultrasound should be reconsidered in the management of abdominal diseases because this examination associated with ultrasound-guided fine-needle biopsy allows, in expert hands, to obtain adequate histological samples avoiding patients to undergo more invasive tests to get a diagnosis.     

Point of care ultrasound (POCUS) telemedicine project in rural Nicaragua and its impact on patient management

Background

Point of care ultrasound (POCUS) is a useful diagnostic tool in medicine. POCUS provides an easy and reproducible method of diagnosis where conventional radiologic studies are unavailable. Telemedicine is also a great means of communication between educators and students throughout the world.

Hypothesis

Implementing POCUS with didactics and hands-on training, using portable ultrasound devices followed by telecommunication training, will impact the differential diagnosis and patient management in a rural community outside the United States.

Materials and methods

This is an observational prospective study implementing POCUS in Las Salinas, a small village in rural western Nicaragua. Ultrasound was used to confirm a diagnosis based on clinical exam, or uncover a new, previously unknown diagnosis. The primary endpoint was a change in patient management. International sonographic instructors conducted didactic and practical training of local practitioners in POCUS, subsequently followed by remote guidance and telecommunication for 3 months.

Results

A total of 132 patients underwent ultrasound examination. The most common presentation was for a prenatal exam (23.5 %), followed by abdominal pain (17 %). Of the 132 patients, 69 (52 %) were found to have a new diagnosis. Excluding pregnancy, 67 patients of 101 (66 %) were found to have a new diagnosis. A change in management occurred in a total of 64 (48 %) patients, and 62 (61 %) after excluding pregnancy.

Conclusion

Implementing POCUS in rural Nicaragua led to a change in management in about half of the patients examined. With the appropriate training of clinicians, POCUS combined with telemedicine can positively impact patient care.     

An ultrasound examination of tongue movement during swallowing

Six female adults were studied during the production of four single swallows each, using real-time ultrasound. A pellet was affixed to the tongue at the junction between the (calculated) anterior third and posterior two-thirds of the tongue surface. Direction, rate, and extent of pellet movement were measured and used to create stages of tongue blade movement during swallowing. Pellet movement was then compared to the three stages of hyoid movement (ascent, steady, descent). Anterior-posterior and superior-inferior components of pellet movement were examined and discussed.     

Endocavitary contrast‐enhanced ultrasound: A technique whose time has come?

Endocavitary use of contrast agents in sonography (US) is a relatively new method in diagnostic imaging, competing against gray‐scale US, fluoroscopy, and endoscopy. This article describes established indications, demonstrates the techniques of evolving applications, and discusses their potential benefits. These benefits include the ability to obtain precise information about the placement of drains and the extent of fluid collections, and to accurately identify the location and features of strictures in various organs, and those of complications of fluid collections or abscesses, without resorting to ionizing radiation. © 2014 Wiley Periodicals, Inc.

A rare giant placental chorioangioma with favorable outcome: A case report and review of the literature

We describe a rare giant placental chorioangioma in a patient who had a favorable outcome with close prenatal surveillance in a 28‐year‐old primigravida who was referred to our clinic for ultrasound evaluation of a suspected placental mass at 23 weeks' gestation. A detailed ultrasound scan revealed a well‐circumscribed, echogenic lesion measuring 11.0 × 10.3 × 7.3 cm and protruding into the amniotic cavity. A diagnosis of placental chorioangioma was made and intensive prenatal surveillance was scheduled. A small‐for‐gestational age (2,325 g) but normal female neonate was delivered at 37 weeks by cesarean section and discharged from hospital on the second day of the delivery. A giant chorioangioma may not cause any adverse effect to the fetus and may not require any medication or invasive intervention. © 2014 Wiley Periodicals, Inc.

Sonographic appearance of uterine lymphoma: Case report and review of the literature

Uterine lymphoma is rare and tends to be misdiagnosed due to lack of specific radiologic features. Few reports have been published on the sonographic characteristics of uterine lymphoma. We present a case report of uterine lymphoma manifested by a fast growing uterus and describe the sonographic findings. © 2014 Wiley Periodicals, Inc. J Clin Ultrasound, 43 :59–63, 2015     

Can Sonography Distinguish a Supraorbital Notch From a Foramen?

Diagnostic tools for evaluating the supraorbital rim in preparation for nerve decompression surgery in patients with chronic headaches are currently limited. We evaluated the use of sonography to diagnose the presence of a supraorbital notch or foramen in 11 cadaver orbits. Sonographic findings were assessed by dissecting cadaver orbits to determine whether a notch or foramen was present. Sonography correctly diagnosed the presence of a supraorbital notch in 7 of 7 cases and correctly diagnosed a supraorbital foramen in 4 of 4 cases. We found that sonography had 100% sensitivity in diagnosing a supraorbital notch and foramen. This tool may therefore be helpful in characterizing the supraorbital rim preoperatively and may influence the decision to use a transpalpebral or endoscopic approach for supraorbital nerve decompression as well as the decision to use local or general anesthesia.
