Unique morphological variations of transient midventricular syndrome: a case series-review.

ABSTRACT: Older individuals (especially women) enduring an inciting emotional or physical event are prone to developing left ventricular ballooning syndrome. Ballooning of apical distribution is the most common type. However, a midventricular variant is increasingly reported. As this variant becomes further delineated, we describe a case series in which various morphological patterns of midleft ventricular segments are seen. Each case involves a female patient with a presumptive diagnosis of acute coronary syndrome, who upon further cardiac workup demonstrated normal epicardial coronary blood flow. Subsequent cardiac imaging, including transthoracic echocardiography, revealed unique midventricular dilation and akinesis, with preserved or hypercontractility of the basal and apical segments. However, more unique to this, was the fact that the left ventricular regional wall motion abnormalities were of either "symmetric" ballooning morphology, involving all mid segments of the left ventricle; or more dramatically, "asymmetric" ballooning morphology, which involves abnormal regional motion of only a focal left ventricular wall. Furthermore, we review current literature on midventricular ballooning and propose likely mechanisms and optimal treatment strategies in the face of potential complications of midventricular ballooning syndrome.

Project description:The existence of a variety of symptoms with a duration beyond the acute phase of COVID-19, is referred to as post-COVID syndrome (PCS). We aimed to report a series of patients with PCS attending a Post-COVID Unit and offer a comprehensive review on the topic. Adult patients with previously confirmed SARS-CoV-2 infection and PCS were systematically assessed through a semi-structured and validated survey. Total IgG, IgA and IgM serum antibodies to SARS-CoV-2 were evaluated by an electrochemiluminescence immunoassay. A systematic review of the literature and meta-analysis were conducted, following PRISMA guidelines. Univariate and multivariate methods were used to analyze data. Out of a total of 100 consecutive patients, 53 were women, the median of age was 49 years (IQR: 37.8-55.3), the median of post-COVID time after the first symptoms was 219 days (IQR: 143-258), and 65 patients were hospitalized during acute COVID-19. Musculoskeletal, digestive (i.e., diarrhea) and neurological symptoms including depression (by Zung scale) were the most frequent observed in PCS patients. A previous hospitalization was not associated with PCS manifestation. Arthralgia and diarrhea persisted in more than 40% of PCS patients. The median of anti-SARS-CoV-2 antibodies was 866.2 U/mL (IQR: 238.2-1681). Despite this variability, 98 patients were seropositive. Based on autonomic symptoms (by COMPASS 31) two clusters were obtained with different clinical characteristics. Levels of anti-SARS-CoV-2 antibodies were not different between clusters. A total of 40 articles (11,196 patients) were included in the meta-analysis. Fatigue/muscle weakness, dyspnea, pain and discomfort, anxiety/depression and impaired concentration were presented in more than 20% of patients reported. In conclusion, PCS is mainly characterized by musculoskeletal, pulmonary, digestive and neurological involvement including depression. PCS is independent of severity of acute illness and humoral response. Long-term antibody responses to SARS-CoV-2 infection and a high inter-individual variability were confirmed. Future studies should evaluate the mechanisms by which SARS-CoV-2 may cause PCS and the best therapeutic options.

Project description:The term transient epileptic amnesia was coined in 1990 to describe a form of epilepsy causing predominantly amnestic seizures which could be confused with episodes of Transient Global Amnesia. Subsequent descriptions have highlighted its association with 'atypical' forms of memory disturbance including accelerated long-term forgetting, disproportionate autobiographical amnesia and topographical amnesia. However, this highly treatment-responsive condition remains under-recognized and undertreated. We describe the clinical and neuropsychological features in 65 consecutive cases of transient epileptic amnesia referred to our study, comparing these to our previous cohort of 50 patients and to those reported in 102 literature cases described since our 2008 review. Findings in our two cohorts are substantially consistent: The onset of transient epileptic amnesia occurs at an average age of 62 years, giving rise to amnestic episodes at a frequency of around 1/month, typically lasting 15-30 min and often occurring on waking. Amnesia is the only manifestation of epilepsy in 24% of patients; olfactory hallucinations occur in 43%, motor automatisms in 41%, brief unresponsiveness in 39%. The majority of patients describe at least one of the atypical forms of memory disturbance mentioned above; easily provoked tearfulness is a common accompanying feature. There is a male predominance (85:30). Epileptiform changes were present in 35% of cases, while suspected causative magnetic resonance imaging abnormalities were detected in only 5%. Seizures ceased with anticonvulsant treatment in 93% of cases. Some clinical features were detected more commonly in the second series than the first, probably as a result of heightened awareness. Neuropsychological testing and comparison to two age and IQ-matched control groups (n = 24 and 22) revealed consistent findings across the two cohorts, namely elevated mean IQ, preserved executive function, mild impairment at the group level on standard measures of memory, with additional evidence for accelerated long-term forgetting and autobiographical amnesia, particularly affecting episodic recollection. Review of the literature cases revealed broadly consistent features except that topographical amnesia, olfactory hallucinations and emotionality have been reported rarely to date by other researchers. We conclude that transient epileptic amnesia is a distinctive syndrome of late-onset limbic epilepsy of unknown cause, typically occurring in late middle age. It is an important, treatable cause of memory loss in older people, often mistaken for dementia, cerebrovascular disease and functional amnesia. Its aetiology, the monthly occurrence of seizures in some patients and the mechanisms and interrelationships of the interictal features-amnestic and affective-all warrant further study.

Project description:BackgroundCholesterol embolization syndrome (CES) is an uncommon but well-known cause of renal failure in native kidneys, but little is known about CES in kidney transplant recipients. The aim of this study was to determine the incidence, clinical characteristics, histopathology, and prognosis of CES after kidney transplantation.MethodsCES cases in both transplanted and native kidneys (control group) were identified by searching the databases of the divisions of Nephrology and Pathology of our institution. Clinical data were retrospectively collected. Biopsies were classified according to the latest Banff 2019 Update. Second, a systematic literature search was performed (December 01, 2020) of Ovid MEDLINE, EMBASE, the Cochrane Central Register of controlled trials, Google Scholar, and Web of Science.ResultsCES was observed in for-cause biopsies of 11 out of 2350 (0.47%) kidney transplant recipients transplanted between January 1, 2006, and December 31, 2018 (0.0009 cases per person-year). All patients had ≥1 cardiovascular risk factor, and 9 donors were expanded criteria donors. Graft loss occurred in 27.3% of the patients diagnosed with CES. Eight transplant biopsies with CES were also classified as biopsy-proven acute rejection. Transplant biopsies showed signs of inflammation (arteritis, n = 7; interstitial inflammation, n = 5; tubulitis, n = 7). One patient with CES in a native kidney was identified. The biopsy of the native kidney only showed arteritis and classified as an isolated "v" lesion. The literature search resulted in 188 unique articles of which 20 were included. A total of 47 cases of CES after kidney transplantation was reported. Cholesterol emboli were found in <1% of all kidney transplant biopsies. In 57.8% of the kidney transplant biopsies with CES described in literature, concomitant inflammation was present.ConclusionsCES is an uncommon cause of kidney transplant failure, although the incidence of CES may be underestimated. CES may mimic rejection as it can be accompanied by arteritis.

Project description:ObjectiveWolf-Hirschhorn syndrome (WHS) is a congenital malformation syndrome with poor prognosis. It is associated with a heterozygous deletion of chromosome 4p16.3. Adequate knowledge of prenatal phenotypes and proper prenatal counseling are essential for intrauterine diagnosis.MethodWe retrospectively analyzed 11 prenatal cases of WHS diagnosed using low-depth whole-genome sequencing (copy number variation sequencing) performed at our hospital from May 2017 to September 2022 and reviewed their prenatal ultrasound reports in detail. We also analyzed WHS cases (including prenatal and postnatal) with abnormal prenatal ultrasound findings in the published literature over the past 20 years.ResultsAmong the 11 fetuses with a prenatal diagnosis of WHS in our hospital, four cases showed abnormal prenatal ultrasound findings, including shrunken kidneys, ventricular septal defect, a small stomach, fetal growth restriction (FGR), enlarged posterior fossa, and soft ultrasonic markers. Our four cases were combined with 114 published WHS cases with prenatal ultrasound abnormalities from other medical institutions. Of the 118 cases, 59.3% (70 of 118) were multiple malformations. The most frequent ultrasound features observed in all 118 cases were FGR (76.3%, 90 of 118), followed by facial anomalies (28.8%, 34 of 118), central nervous system anomalies (27.1%, 32 of 118), and soft ultrasound markers (23.7%, 28 of 118). Other less common phenotypes included cardiac anomalies (19.5%, 23 of 118), genitourinary anomalies (19.5%, 23 of 118), increased NT/NF (12.7%, 15 of 118), skeletal anomalies (11.9%, 14 of 118), a single umbilical artery (10.2%, 12 of 118), gastrointestinal anomalies (9.3%, 11 of 118), oligohydramnios (8.5%, 10 of 118), cystic hygroma (5.1%, six of 118), hydrops/pleural effusion/ascites (2.5%, three of 118), and polyhydramnios (2.5%, three of 118).ConclusionThis study improved our understanding of the prenatal presentation of WHS by analyzing prenatal ultrasound abnormalities. The timely identification of prenatal ultrasound abnormalities can provide accurate consultation for pregnant women, improve the prenatal detection of WHS, and enable early prenatal management and intervention of WHS.
