The cellular mechanisms underlying the microvascular dysangiogenesis of bronchopulmonary dysplasia (chronic lung disease of the newborn) remain largely undetermined. We report unusual pulmonary vascular findings in a 27-week-gestation male newborn who died on the second day of life from intractable respiratory failure, following a pregnancy complicated by prolonged membrane rupture and persistent severe oligohydramnios. As expected, postmortem examination revealed pulmonary hypoplasia (lung/body weight ratio: 2...

Hemizygous mutations in the human gene encoding platelet-activating factor acetylhydrolase IB subunit alpha (Pafah1b1), also called Lissencephaly-1, can cause classical lissencephaly, a severe malformation of cortical development. Children with this disorder suffer from deficits in neuronal migration, severe intellectual disability, intractable epilepsy and early death. While many of these features can be reproduced in Pafah1b1(+/-) mice, the impact of Pafah1b1(+/-) on the function of individual subpopulations of neurons and ultimately brain circuits is largely unknown...

The molecular mechanisms underlying the phagocytosis of apoptotic cells need to be elucidated in more detail because of its role in immune and inflammatory intractable diseases. We herein developed an experimental method to investigate phagocytosis quantitatively using the fruit fly Drosophila, in which the gene network controlling engulfment reactions is evolutionally conserved from mammals. In order to accurately detect and count engulfing and un-engulfing phagocytes using whole animals, Drosophila embryos were homogenized to obtain dispersed cells including phagocytes and apoptotic cells...

Artificial skin has achieved considerable therapeutic results in clinical practice. However, artificial skin treatments for wounds in diabetic patients with impeded blood flow or with large wounds might be prolonged. Cell-based therapies have appeared as a new technique for the treatment of diabetic ulcers, and cell-sheet engineering has improved the efficacy of cell transplantation. A number of reports have suggested that adipose-derived stem cells (ASCs), a type of mesenchymal stromal cell (MSC), exhibit therapeutic potential due to their relative abundance in adipose tissue and their accessibility for collection when compared to MSCs from other tissues...

Raised intracranial pressure (ICP) is associated with worse outcomes after acute brain injury, and clinical guidelines advocate early treatment of intracranial hypertension. ICP-lowering therapies are usually administered in a stepwise manner, starting with safer first-line interventions, while reserving higher-risk options for patients with intractable intracranial hypertension. Decompressive craniectomy is a surgical procedure in which part of the skull is removed and the underlying dura opened to reduce brain swelling-related raised ICP; it can be performed as a primary or secondary procedure...

Cross-sector collaboration is increasingly relied upon to tackle society's pressing and intractable problems. Chief among societal problems are unfavorable structural and social determinants of health. The ability to positively change these health determinants rests on the collaborative processes and structures of governance across diverse sectors in society. The purpose of this article is to present a conceptual framework that sheds light on the basic requirements of cross-sector collaboration for social change to promote the health of populations...

Many patients of advanced Parkinson's disease (PD) suffer from intractable axial symptoms (severe gait and postural impairments), which were recently speculated to be more relevant to cholinergic degeneration in the brainstem than dopaminergic degeneration in the substantia nigra compacta (SNc). To investigate the role of the cholinergic cells of the pedunculopontine tegmental nucleus (PPTg) on motor deficits, especially the axial motor impairments, we measured and analyzed the gait performance of sham lesion rats, SNc dopaminergic lesion rats, PPTg cholinergic lesion rats, and combined lesion rats by using the CatWalk system...

OBJECTIVE: There is a close relationship between upper and lower respiratory tract diseases. Chronic rhinosinusitis patients frequently have lung diseases including asthma and chronic obstructive pulmonary disease. Eosinophilic chronic rhinosinusitis is considered a refractory and intractable subtype of chronic rhinosinusitis. However, there has been no report on pulmonary function in patients with eosinophilic chronic rhinosinusitis. The purpose of this study is to examine the pulmonary function in eosinophilic chronic rhinosinusitis patients and non-eosinophilic chronic rhinosinusitis patients, and evaluate clinical factors associated with the pulmonary function of these patients...

Chronic constipation is a common gastrointestinal disorder disproportionately affecting the elderly. Immobility, polypharmacy, and physiologic changes contribute to its increased prevalence in this population. Unidentified and undertreated constipation leads to a significant negative impact on quality of life and an increase in healthcare spending. Careful physical examination and exploration of the clinical history can unmask primary and secondary forms of constipation, guiding diagnostic and therapeutic considerations...

The term "long-term epilepsy-associated tumor (LEAT)" encompasses brain lesions associated with drug-resistant epilepsy over a long duration (≥2 years). Notably, some LEATs do not fit into any of the classifications of the World Health Organization (WHO). Herein, we report a LEAT that occurred in the left amygdala of a 16-year-old patient with intractable epilepsy. Histological examination of the resected amygdala revealed diffusely infiltrating tumor cells in the cortex. Perineuronal satellitosis and perivascular aggregation of tumor cells were apparent, along with mild nuclear enlargement and cytologic atypia...

BACKGROUND: Trismus is a problem commonly encountered by the dental practitioner. It has a number of potential causes, and its treatment will depend on the cause. However, there are very few reports of trismus due to fibrodysplasia ossificans progressiva (FOP) following third molar surgery. CLINICAL PRESENTATION: FOP is a rare human genetic disorder with characteristic clinical features like progressive formation of extraskeletal bone or heterotopic ossification and congenital malformation of the great toes...

Over the past 2 decades, the incidence of childhood obesity has risen dramatically. This recent rise in childhood obesity is particularly concerning as adults who were obese during childhood develop type II diabetes that is intractable to current forms of treatment compared with individuals who develop obesity in adulthood. While the mechanisms responsible for the exacerbated diabetic phenotype associated with childhood obesity is not clear, it is well known that childhood is an important time period for the establishment of normal white adipose tissue in humans...

BACKGROUND: Intractable pruritus of cholestasis leads to significant morbidity. Therapeutic plasma exchange (TPE) has been shown to be an effective alternative in the setting of refractory pruritus associated with cholestatic liver disease based on several individual reports. Due to rarity of this approach to intractable pruritus, the literature is sparse and therefore TPE, as a treatment for refractory pruritus is currently not in the apheresis guidelines. We present three additional patients with severe intractable pruritus of cholestasis successfully treated with plasma exchange to add to the mounting literature showing this as an effective and safe adjunctive therapy...

Recent decades have witnessed a rapid worldwide increase in chronic inflammatory disorders such as asthma. CD4(+) T helper 2 cells play critical roles in the pathogenesis of allergic airway inflammation, and CD69 expression on activated CD4 T cells is required to induce allergic inflammation in tissues. However, how CD69 mechanistically controls allergic inflammation remains poorly defined. In lymphoid tissues, CD69 regulates cellular retention through inhibition of S1P1 expression and requires no specific ligands to function...
