Recurrent pericarditis is a state of repetitive inflammation of the pericardium with intervals of remission. The etiology of recurrent pericarditis is still largely unknown, yet most causes are presumed to be immune mediated. Genetic factors, including human leukocyte antigen (HLA) haplotypes, can be involved in dysregulation of the immune system and as a predisposition to several autoimmune conditions, including recurrent pericarditis. Several diseases are frequently associated with such manifestations. They include systemic lupus erythematosus, familial Mediterranean fever, and tumor necrosis factor receptor-associated periodic syndrome. However, idiopathic recurrent pericarditis remains the most frequently observed clinical condition and the conundrum of this disease still needs to be solved.

Background: Hysterectomy is common in the management of symptomatic uterine prolapse. Vaginal wall repair is often necessary, for which vaginal mesh remains a popular option.

Objectives: To evaluate the risk of mesh erosion following mesh-augmented vaginal prolapse repair, with or without concomitant vaginal hysterectomy.

Methods: This retrospective cohort comprised 70 women who underwent vaginal mesh-augmented pelvic organ prolapse repair from 2007 to 2010. Of the participants, 36 (51.4%) had a vaginal hysterectomy concomitant to the anterior and/or posterior vaginal mesh repair (hysterectomy group) and 34 (48.6%) underwent mesh repair without vaginal hysterectomy (no hysterectomy group).

Results: There were no inter-group differences in age, parity, menopausal state, hormonal use, or presenting symptoms. Previous prolapse repair surgery was much more common in the no hysterectomy group (29.4% vs. 5.5%, P = 0.01). Eleven patients (32.3%) in the no hysterectomy group had previously undergone hysterectomy. Anterior mesh repair was performed in 77.7% and 67.6% of hysterectomy and no hysterectomy patients, respectively. Posterior mesh repair was performed in 27.7% and 44.1%, respectively. One patient in the hysterectomy group underwent immediate removal of mesh due to infection. Surgically treated mesh erosion (limited local excision) occurred in three patients (8.3%) in the hysterectomy group (3, 16, and 18 months following surgery) and in two patients (5.8%) in the no hysterectomy group at 6 months following surgery (P = 0.67).

Conclusions: Vaginal mesh-augmentation concomitant with vaginal hysterectomy for pelvic organ prolapse repair does not carry an increased risk of erosion.

Background: Several studies have addressed the issue of undetected uterine pathology in women undergoing hysterectomy for pelvic organ prolapse (POP). However, these studies differ largely with respect to the incidence of malignancy found, study population, and preoperative evaluation.

Objectives: To assess the risk of unexpected pre-malignant and malignant uterine pathological findings after vaginal hysterectomy for POP repair, in a single medical center in Israel.

Methods: A retrospective study was performed of all patients who underwent vaginal hysterectomy due to symptomatic POP between January 1990 and April 2015 in a single tertiary medical center. Selected clinical and pathological data were retrieved from the computerized medical records. All specimens were routinely sent for histopathological assessment. All women were managed according to a uniform protocol that required the presence of a preoperative normal Pap smear, and included preoperative transvaginal sonography and endometrial biopsy when indicated. Patients in whom premalignant or malignant lesions were found preoperatively were not included in the study.

Results: The study comprised 667 patients. The overall rate of malignant or significant premalignant pathologies (6 cases) was 0.89%, including one (0.14%) case of endometrial carcinoma. All premalignant and malignant pathologies were found only in post-menopausal patients. The rate of significant endometrial pathological lesions found in asymptomatic post-menopausal women was only 0.35%.

Conclusions: The rate of preoperatively undetected abnormal histopathological findings in patients who undergo vaginal hysterectomy due to POP is very low, and therefore more extensive preoperative evaluation is not warranted in them.

Background: Computed tomography (CT) brain perfusion is a relatively new imaging method that can be used to differentiate patients following epileptic seizures in the setting of acute neurological deficits (e.g., hemiparesis, hemiplegia, hemianopsia, aphasia) who arrive at the emergency room with a suspected stroke.

Objectives: To evaluate brain perfusion changes in patients who had an epileptic seizure.

Methods: We retrospectively identified 721 patients who presented at our stroke center between 2012 and 2015 with a suspected acute stroke and underwent examination thorough a stroke protocol, including cerebral CT perfusion (CTP) and CT angiography (CTA) within 8 hours from the onset of symptoms. 

Results: Out of 721 patients, 25 presented with ictal electroencephalography (EEG) findings within 24–72 hours from symptom onset without evidence of vascular occlusion on CTA. While 15 patients had to be excluded from the study due to concomitant brain pathology, we found a specific reduction in cerebral blood volume and cerebral blood flow occurring at the ictal zone, which was identified by a post hoc EEG investigation. 

Conclusions: Our study shows that CTP is an easily accessible tool in emergency department setting for the detection of changes in blood flow dynamics among postictal patients. Thus, we propose the use of CTP in emergency settings to discriminate between postictal changes and acute vascular events. 

 

Obstetric antiphospholipid syndrome (Obs-APS) is one of the most commonly identified causes of recurrent pregnancy loss and its accurate diagnosis is a requirement for optimal treatment. Some patients do not fulfill the revised Sapporo classification criteria, the original APS classification criteria, and are considered to be non-criteria Obs-APS. In these patients with non-criteria, there is controversy about their inclusion within the spectrum of APS and eventually their treatment as having Obs-APS. A subset of patients may also have clinical characteristics of Obs-APS even though lupus anticoagulant (LA), anticardiolipin antibodies, and anti-β2-glycoprotein I (aβ2GPI) antibodies are consistently negative. These patients are recognized as seronegative Obs-APS.

We reviewed evidence of non-criteria Obs-APS and discuss a case of a woman with a diagnosis of active systemic lupus erythematosus (SLE) and non-criteria Obs-APS with four consecutive pregnancy losses. After an accurate diagnosis the patient received prenatal counseling and benefited from the optimal treatment of Obs-APS that led to a successful pregnancy. The applicability of this successful experience about outcomes in women with non-criteria, or seronegative, Obs-APS is also evaluated.
