Exercise induced dyspnoea (EID) is a common manifestation in children and adolescents. Although EID is commonly attributed to exercise induced bronchoconstriction, several conditions other than asthma can cause EID in otherwise healthy children and adolescents. Cardiopulmonary exercise testing (CPET) offers a non-invasive comprehensive assessment of the cardiovascular, ventilatory and metabolic responses to exercise and is a powerful diagnostic and prognostic tool. CPET is a reproducible, non-invasive form of testing that allows for comparison against age- and gender-specific norms. CPET can assess the child's exercise capacity, determine the limiting factors associated with this, and be used to prescribe individualised interventions. EID can occur due to asthma, exercise induced laryngeal obstruction, breathing pattern disorders, chest wall restriction and cardiovascular pathology among other causes. Differentiating between these varied causes is important if effective therapy is to be initiated and quality of life improved in subjects with EID.

Patients with advanced seminoma have an exceedingly favorable prognosis. Studies aiming to reduce the total treatment burden and side effects in patients with well-defined disease and very good prognosis are warranted.

In a prospective observational study, patients with advanced stage seminoma were treated with bleomycin, etoposide, and cisplatin (BEP) or EP according to guidelines. Fluorodeoxyglucose with positron emission tomography and computed tomography (FDG-PET/CT) examinations were performed at baseline, after 2 cycles (PET/CT2) in all patients, and after chemotherapy at the physician's discretion. Disease response to treatment assessed by PET/CT was qualitatively evaluated by 2 independent nuclear medicine physicians. Contrast-enhanced CT scans were also performed according to guidelines (at baseline, after treatment, during follow-up). The study's primary endpoint was to evaluate the association between PET/CT2 findings and relapse-free survival.

From January 2009 to January 2017, a total of 75sted within larger prospective clinical trials of chemotherapy deescalation.

There is limited information on the frequency of complications among older adults after oncological thoracic surgery in the modern era. We hypothesized that morbidity and mortality in older adults with lung cancer undergoing lobectomy is low and different than that of younger patients undergoing thoracic surgery.

All patients undergoing lobectomy at a large volume academic center between May 2016 and May 2019 were included. Patients were prospectively monitored to grade postoperative morbidity by organ system, based on the Clavien-Dindo classification. Patients were divided into two groups Group 1 included patients 65-91 years of age, and Group 2 included those <65 years.

Of 680 lobectomies in 673 patients, 414(61%) were older than 65 years of age (group 1). Median age at surgery was 68 years (20-91). Median hospital stay was 4 days (1-38) and longer in older adults. Older adults experienced higher rates of grade II and IV complications, mostly driven by an increased incidence of delirium, atrial fib MI approaches and broad-based, geriatric-focused perioperative management of older adults undergoing lobectomy.

Laparoscopic hepatectomy (LH) has become increasingly popular for liver neoplasms, but its safety and effectiveness remain controversial. Hepatic hemangiomas are the most common benign liver neoplasm; the main approaches to hepatic hemangiomas include open hepatectomy (OH) and LH. In this study, we compared early outcomes between patients undergoing OH and those with LH.

Patients underwent OH or LH in our hospital for hepatic hemangiomas between December 2013 and December 2017 were enrolled. All patients underwent comprehensive preoperative evaluations. The clinicopathological index and risk factors of hemangioma resection were assessed.

In total, 41 patients underwent OH while 53 underwent LH. There was no significant difference in any preoperative clinical variables, including liver function, prothrombin time, or platelet count. Hepatic portal occlusion time and operative time were 39.74 vs. 38.35minutes (P=0.717) and 197.20 vs. 203.68minutes (P=0.652) in the OH and LH groups, respectively. BIBO 3304 No mortality nor significant perioperative complications were observed between the two groups. In LH group, two cases were converted to OH, one for an oversized tumor and the other for hemorrhage. Compared with OH patients, those with LH had less blood loss (361.69 vs. 437.81mL, P=0.024), shorter postoperative hospital stay (7.98 vs. 11.07 days, P=0.001), and lower postoperative C-reactive protein (43.63 vs. 58.21mg/L, P=0.026).

LH is superior to OH in terms of postoperative recovery and blood loss for selected patients with hepatic hemangioma.

LH is superior to OH in terms of postoperative recovery and blood loss for selected patients with hepatic hemangioma.Mitochondrial diseases, due to nuclear or mitochondrial genome mutations causing mitochondrial dysfunction, have a wide range of clinical features involving neurologic, muscular, cardiac, hepatic, visual, and auditory symptoms. Making a diagnosis of a mitochondrial disease is often challenging since there is no gold standard and traditional testing methods have required tissue biopsy which presents technical challenges and most patients prefer a non-invasive approach. Since a diagnosis invariably involves finding a disease-causing DNA variant, new approaches such as next generation sequencing (NGS) have the potential to make it easier to make a diagnosis. We evaluated the ability of our traditional diagnostic pathway (metabolite analysis, tissue neuropathology and respiratory chain enzyme activity) in 390 patients. The traditional diagnostic pathway provided a diagnosis of mitochondrial disease in 115 patients (29.50%). Analysis of mtDNA, tissue neuropathology, skin electron microscopy, respiratory chain enzyncing (BGS) approach (using both a nWES and optimized mtDNA analysis to include large deletions) should be the first step in investigating for mitochondrial diseases. There may still be a role for tissue biopsy in unsolved cases or when the diagnosis is still not clear after NGS studies.

The Self-reported Foot and Ankle Score (SEFAS) is a patient-reported outcome measure used to evaluate foot and ankle disorders. The purpose of this study was to translate, cross-culturally adapt and validate the Danish language version of the SEFAS in patients with ankle-related fractures.

Forward-backward translation, cross-cultural adaption and validation were performed. In total, 125 patients completed the SEFAS-DK and the Danish version of American Orthopaedic Foot and Ankle Score (AOFAS-DK) at three time points after the date of fracture. The evaluation was performed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines.

The intra-class correlation coefficient (ICC) level of the SEFAS-DK total score was 0.93 (95% confidence interval [CI] 0.88-0.96). Cronbach's alpha (CA) for the SEFAS-DK was 0.93, while the floor and ceiling effect at week 6 post-injury was 22.4%. Construct validity was correlated with the AOFAS, and >75% of the pre-defined hypotheses could be confirmed. Responsiveness was analysed using longitudinal data. The minimal clinical important change (MCIC) showed that the SEFAS-DK detects changes in physical function over time.

The Danish version of the SEFAS showed overall good reliability, validity and responsiveness. SEFAS-DK can be used to evaluate physical function in patients with ankle-related fractures.

Examples are the conversion of somatic cells to induced pluripotent stem cells and rejuvenation of the germline with each generation. We posit that these processes converge to the same 'ground zero', the mid-embryonic state characterized by the lowest biological age where both organismal life and aging begin. It may also be related to the phylotypic state. The ground zero model clarifies the relationship between aging, development, rejuvenation, and de-differentiation, which are distinct throughout life. By extending the rejuvenation phase during early embryogenesis and editing the genome, it may be possible to achieve the biological age at the ground zero lower than that achieved naturally.

A specific aspect of the hypospadias phenotype that may contribute to long-term outcomes is the presence of ventral penile curvature and the adequacy of its surgical correction. The current gold standard to assess this angle is intraoperative goniometry of an erect penis. 3-dimensional (3D) mapping technologies may overcome the limitations of these traditional methods through their combination of digital image and geometric replication to produce consistent 3D digital forms of a physical structure. The aim of this study is to evaluate the measurement accuracy and reliability of handheld 3D mapping technologies versus standard goniometry for angle assessment in a laboratory setting.

Blocks with specified angles (10-45°) were printed using a Zortrax M200 3D printer (±0.2% accuracy). Following the completion of standardized training, blinded participants measured each block angle using a baseline digit goniometer. Additionally, complete digital models of the blocks were created using 3D mapping technologies. are an important step toward reliable, reproducible phenotypic analysis of congenital genitourinary conditions in future intraoperative and database development applications.

Vaginal lesions are rare and of various types in children. Clinical presentation is generally undifferenciated. Histological examination is fundamental to ascertain the nature of the lesion. Regarding tumoral lesions, histological subtypes encountered are radically different from those seen in adults, dominated by stromal benign lesions.

The aim of this retrospective study was to describe characteristics and pathological aspects of pediatric vaginal lesions, diagnosed in a single pediatric experienced center.

A database analysis was performed on all vaginal samples of patients under 18 years old received in a pediatric-specialized pathology laboratory of an academic hospital, over a 26-year period.

Among 36 vaginal tissue samples reported, a total of 15 tumoral or pseudotumoral processes was recorded. Primitive malignant tumors included embryonal rhabdomyosarcoma (n=3) and germ-cell tumors, yolk-sac type (n=2). Benign tumoral or pseudotumoral processes included inflammatory stromal polyps (n=8), epideocesses. Myogenin immunostain must be systematic in case of vaginal polypoid mass, in order to rule out malignancy.

We confirmed the rarity and the diversity of vaginal lesions in children. Vaginoscopy and biopsy sample should be systematic, given the non-specific presentation of tumoral processes. Myogenin immunostain must be systematic in case of vaginal polypoid mass, in order to rule out malignancy.The endocannabinoid system (ECS) is a widespread neuromodulatory network involved in the developing central nervous system as well as playing a major role in tuning many cognitive and physiological processes. The ECS is composed of endogenous cannabinoids, cannabinoid receptors, and the enzymes responsible for the synthesis and degradation of endocannabinoids. In addition to its endogenous roles, cannabinoid receptors are the primary target of Δ9-tetrahydrocannabinol, the intoxicating component of cannabis. In this review, we summarize our current understanding of the ECS. We start with a description of ECS components and their role in synaptic plasticity and neurodevelopment, and then discuss how phytocannabinoids and other exogenous compounds may perturb the ECS, emphasizing examples relevant to psychosis.
