Autosomal dominant mitochondrial DNA depletion syndrome (MTDPS-12A) is characterized by severe hypotonia from birth due to a mutation in the adenine nucleotide translocator 1 (ANT1).

A 4-year-old female patient diagnosed with neonatal-onset mitochondrial disease, who had good cognitive function while receiving antiepileptic treatment, presented with sudden-onset status epilepticus with facial and limb myoclonus persisting for more than 30min. Subsequently, she developed epileptic encephalopathy. Brain MRI showed progressive ventricular enlargement and marked white matter atrophy. She was unable to perform verbal communication or make eye contact and fingertip movements. She lacked any signs of cardiomyopathy. Sanger sequencing demonstrated a heterozygous de novo mutation of c.239G>A (p.Arg80His) in SLC25A4. Her right quadriceps muscle tissue showed lowered complexes I, III, and IV activities and mitochondria DNA depletion (mitochondria/nuclear DNA 14.6±2.2%) through the quantitative polymerase chain reaction. She was definitively diagnosed with MTDPS-12A.

Status epilepticus causes encephalopathy in patients with MTDPS-12A. Reducing the energy requirement on the cardiac muscle and brain may be a treatment strategy for patients with MTDPS-12A. Therefore, seizure management and preventive treatment of status epilepticus are considered to be important for maintaining neurodevelopmental outcomes.

In capitellar osteochondritis dissecans (OCD), unstable lesions generally demonstrate signs of subchondral sclerosis. We postulate that OCD lesions have abnormal subchondral bone density. We aimed to quantify the subchondral bone thickness around OCD lesions using conventional computed tomography (CT) imaging.

This retrospective study included 15 patients with capitellar OCD (OCD group) and 12 patients with an unaffected radio-capitellar joint (control group). We constructed 3-dimensional humerus models using CT data and quantified the bone density with colored contour mapping to determine the subchondral bone thickness. We measured the thickness relative to the condylar height at the centroid and lateral, medial, superior, and inferior edge points of the OCD lesion, and compared the findings between the groups. We then correlated the CT measurements with the magnetic resonance imaging measurements.

Subchondral bone thickness at the centroid and lateral, medial, superior, and inferior edges in the OCD group was significantly higher than that in the control group. Correlation analyses revealed that the magnetic resonance imaging measurements highly correlated with the CT subchondral bone measurements.

We found that there is a zone of increased subchondral bone thickness around OCD lesions that should be considered during drilling, microfracture, or other reconstruction methods. We observed a high correlation with low errors between the measurements taken from conventional CT images and the measurements from magnetic resonance imaging, suggesting that both modalities are useful in clinical decision making.

Arm-, region-, tissue-, and condition-specific patient-reported outcome measures (PROMs) are available to address idiopathic mononeuropathy. This study compared PROMs with varying specificities in patients with idiopathic neuropathy of the upper extremity with respect to correlations with each another, sources of variation in scores, and floor and ceiling effects.

One hundred fifty patients (130 with carpal tunnel syndrome, 30 with cubital tunnel syndrome, and 10 with both conditions) completed a nerve-specific PROM (Impact of Hand Nerve Disorders), a condition-specific PROM (Boston Carpal Tunnel Syndrome Questionnaire and/or Patient-Rated Ulnar Nerve Evaluation), and an upper extremity-specific PROM (Patient-Reported Outcomes Measurement Information System Physical Function Upper Extremity 7). selleck products We also gathered demographic and condition-related data (side, electrodiagnostic studies present, muscle atrophy, static loss of sensibility), and patients completed questionnaires measuring self-efficacy, kinesiopto use a single simple, brief, and general PROM to quantify symptom intensity and activity intolerance for both routine patient care and research.

To report the histopathological, electron microscopic, and immunohistochemical findings of tissue samples obtained from patients with radial longitudinal deficiency (RLD) and investigate the contribution of abnormality in soft tissues as a secondary driver of deformity in RLD.

Specimens from radial-sided muscles and tendons were obtained at the time of surgery (either radialization or centralization) from 14 patients with 16 limbs affected with Bayne type 3 and type 4 RLD. The specimens were evaluated using light microscopy, electron microscopy, and immunohistochemical examination.

Among the 16 frozen muscle specimens, 6 (37%) showed normal muscle, while 10 (63%) showed the presence of atrophic fibers. The 6 cases with normal muscle showed no abnormality in fiber type distribution. Six patients showed predominance of type 1 muscle fibers. None of the specimens had myofibroblasts; 4 of 16 specimens had mast cells, and 9 of 16 specimens showed the presence of platelet derived growth factor-positive cells. Features of myofibroblasts (the presence of basal lamina, intercellular junctions, or pinocytic vesicles) were not identified in any specimen on electron microscopy.

The histopathological, electron microscopic, and immunohistochemical findings, in particular the absence of myofibroblasts, in tissue samples obtained from patients with RLD, do not support the assumption of abnormality in soft tissues as a secondary driver of deformity in RLD.

This study provides a preliminary insight into a possible role of soft tissues in the development of the deformity in RLD.

Over time, patients may develop progressive contractures, impairing their ability to type, to perform with fine instruments, or to participate in social activities such as shaking hands. Treatment options for Dupuytren contractures include needle aponeurotomy (NA), injection of collagenase Clostridium histolyticum (CCH) with manipulation of the digits, and surgical fasciectomy. Over the past decade, the use of CCH has increased. Recent studies have provided additional data regarding the pathophysiology, indications, outcomes, and costs associated with the treatment for Dupuytren contractures, and this review highlights these advances.The epididymis is responsible for peripheral immune tolerance of maturing spermatozoa even though these have xeno-antigens foreign to the male and female immune system. The epididymis also produces factors required for fertilization and serves as a sperm repository until the time of ejaculation. These reproduction-relevant epididymal functions occur in the mesonephros-derived duct-system that is composed of absorptive and secretory epithelial cells with the capacity for merocrine and apocrine secretion of proteins, antioxidative- and electrolyte/pH-regulating enzymes and small, non-coding RNAs (sncRNAs), many stored in epididymosomes for sperm adhesion and long-lasting modifications of sperm functions. This paper provides a review summary of current and new knowledge of how the boar epididymis affects the quality of spermatozoa in the ejaculate of breeding boars. There is a particular focus on sperm maturation, survival, function and the role of signaling to the female immune system in fertility modulation. Furthermore, aspects related to the ductus epithelial contributions regarding electrolyte control, protein production, release of epididymosomes that contain sncRNAs are emphasized as are novel associations with fertility of the male, sperm quiescence during storage in the cauda epididymis, and on changes occurring in sperm subsequent to ejaculation.While overall survival has improved significantly for children with cancer over the past 75 years, cancer remains the leading cause of death from disease among children and adolescents. Further, despite the many advances in medical and nursing care, children with cancer still experience significant physical and emotional suffering over the course of their illness, especially at the end of life (EOL). Children endure significant rates of high-intensity medical interventions (e.g., intubation, intensive care unit admission) at the EOL despite many parents, adolescents, and young adult patients identifying home as their preferred location of death. Hospice care has the potential to ease suffering at the EOL and facilitate home deaths, and yet, most children still die in acute care settings without hospice care. Numerous barriers prevent timely enrollment in hospice among children with cancer who are in the EOL period. This report describes the development and testing of a palliative care/EOL communication intervention designed to overcome some of these barriers and improve EOL outcomes (i.e., earlier hospice enrollment, less use of high-intensity medical interventions, reduced pain and suffering) among children with cancer and their parents (i.e., less emotional distress and uncertainty, improved hope and healthcare satisfaction).

Aortic endograft infection is an infrequent but life-threatening complication after endovascular abdominal aortic repair (EVAR). There is no consensus on management of endograft infection and little evidence has been published in our country. Endograft explantation is considered the "gold standard" treatment whereas percutaneous or surgical perigraft and sac drainage associated to antibiotics should be considered and alternative therapy.

We carried out a retrospective and descriptive review of abdominal aortic endograft infections at our tertiary center (Hospital Universitario Cruces) during last ten years (2010-2019).

We describe the clinical and microbiological characteristics of 10 EVAR infections, their management and outcomes. The incidence of graft infection after EVAR was 3%. The mean time to the clinical presentation of infection was 16.9 months (median 4.5 months). The microbiological diagnosis was reached in 100% of cases (predominance of gram-positive species). The overall mortality rate was 50% (although the survival rate was 100% after surgical drainage of the sac).

Perigraft or aneurysm sac aspiration culture shows their diagnostic utility as microbiological diagnosis was reached in all cases despite of blood cultures being only positive in 50% of the samples. Surgical drainage and endograft preservation combined with antibiotherapy show remarkable results. The high heterogeneity in our case series makes difficult to offer general recommendations, thus far, a tailored approach to treatment is suggested.
