Carcinosarcome utérin secondaire à un textilome vaginal : à propos d’un cas et revue de la littérature

Management of abdominal textilomas: A retrospective study

INTRODUCTION

Textilomas are an infrequent but well-known surgical complication. The authors report a series of cases to describe the frequency of abdominal textilomas, the circumstances in which they occur, their clinical and morphological characteristics, and their management, to contextualise these data, which may serve as a basis for preventive measures.

SETTING AND METHOD

This was a monocentric, retrospective, descriptive study conducted over 10 years at a tertiary hospital. The circumstances of the initial intervention, the diagnosis, and the treatment of textiloma cases treated in the said centre were documented.

RESULTS

Twenty-one (21) cases of abdominal textiloma were collected, with an annual frequency of 2.1 cases/year. The cases were predominantly female, with a female-to-male sex ratio of 1.62. The median age of the patients was 37 years. The initial operation was performed in a public facility in 80.95 % of cases. Myomectomy was the main indication (23.81 %). The time for signs to develop before consultation was 16.47 ± 8.82 days. Textiloma extraction was performed in an emergency in 61.90 % of cases. We noted morbidity (38.10 %) and mortality (9.52 %) in our patients.

CONCLUSION

Textilomas are a rare surgical complication, albeit with a high morbidity and mortality rate. Their clinical polymorphism and the difficulties of diagnosis and management mean that prevention is of prime importance.

Foreign bodies of body orifices: A pictorial review

INTRODUCTION

Ingestion, inhalation, and insertion of foreign bodies (FB) are commonly encountered problems in the emergency departments (ED). Radiologists pay a key role in their diagnosis and management. Selecting an appropriate imaging modality is important depending on the route of entry and reported type of FB. Diagnosing FB is time sensitive and requires radiologists to be astute and familiar with varied imaging appearances of FB. In this article, we review imaging features of most common FB seen in clinical practice and their complications.

TEACHING POINTS

SUMMARY: FB in body orifices are frequently seen in the ED. Imaging plays a pivotal role in the management in majority of the cases. In this article, we present several cases of commonly encountered FB.

Ultrasonography in Detection of Vaginal Foreign Bodies in Girls: A Retrospective Study

STUDY OBJECTIVE

In this study we investigated the sonographic features of vaginal foreign bodies in girls and the diagnostic role of combined transperineal and transabdominal ultrasonography in the detection of vaginal foreign bodies in this population. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: A retrospective review of the records of 249 girls seen in the outpatient pediatric and adolescent gynecology clinic of our hospital and referred to our department for sonographic evaluation of suspected vaginal foreign bodies between 2013 and 2016 was performed. All patients were transperineally and transabdominally scanned using an ultrasound machine with 3-MHz and 7.5-MHz transducers. The sonographic features of the detected foreign bodies were recorded and reported. All patients also underwent pelvic radiography. The presence of foreign bodies was confirmed using vaginoscopy.

RESULTS

Two hundred forty-nine patients were included in this study, and vaginal foreign bodies were detected in 181 patients. Vaginal foreign bodies often present in girls aged from 2 to 12 years old. The most common vaginal foreign bodies were toilet paper, beads, small parts of toys, cap of water color brush, and crayons. The overall sensitivity, specificity, positive and negative predictive values of transperineal/transabdominal sonography in the diagnosis of vaginal foreign bodies were 81%, 53%, 82%, and 51%, respectively. The sensitivity, specificity, and positive and negative predictive values of transabdominal sonography were 33%, 49%, 63%, and 21%, respectively. The sensitivity, specificity, and positive and negative predictive values of transperineal sonography were 64%, 49%, 77%, and 33%, respectively. Abnormal findings were detected using x-ray in only 43 of the 181 cases (23.7%). The sensitivity, specificity, and positive and negative predictive values of x-ray were 24%, 91%, 88%, and 31%, respectively. The size of the foreign bodies ranged from 2 mm to 35 mm. For foreign bodies larger than 5 mm, the rate of sonographic accuracy reached 100%. For foreign bodies smaller than 5 mm, 32 false positive results, and 34 false negative results were identified. One hundred thirty-nine of 181 foreign bodies were less than 2 cm from the vaginal orifice (77%). All foreign bodies were hyperechoic compared with adjacent tissues. Some vaginal foreign bodies had characteristic echo patterns. With the exception of 1 patient with a detained AAA battery that caused vaginal ulceration, the other patients had a full recovery.

CONCLUSION

Vaginal foreign bodies were hyperechoic compared with adjacent tissues and often had characteristic echo patterns. The use of combined transperineal and transabdominal ultrasonography might be helpful in diagnosing foreign bodies, especially when the size of the foreign body is larger than 5 mm. Therefore, ultrasonography might be preferred for the initial evaluation of suspected vaginal foreign bodies, because it is a noninvasive, radiation-free, and inexpensive technique.

The role of mitochondria in the oncogenic signal transduction

Mitochondria are intracellular organelles thought to have evolved from an alphaproteobacterium engulfed by the ancestor of the eukaryotic cell, an archeon, two billion years ago. Although mitochondria are frequently recognised as the "power plant" of the cell, the function of these organelles go beyond the simple generation of ATP. In fact, mounting evidence suggests that mitochondria are involved in several cellular processes, from regulation of cell death to signal transduction. Given this important role in cell physiology, mitochondrial dysfunction has been frequently associated with human diseases including cancer. Importantly, recent evidence suggests that mitochondrial function is directly regulated by oncogenes and tumour suppressors. However, the consequences of deregulation of mitochondrial function in tumour formation are still unclear. In this review, I propose that mitochondria play a pivotal role in shaping the oncogenic signalling cascade and that mitochondrial dysfunction, in some circumstances, is a required step for cancer transformation.
