Emphysematous infection of the urinary tract is a rapidly progressive, necrotizing infection which results into collection of gas and subsequent destruction of the tissues. Although very rare among general population, such necrotizing infection is common, particularly among those with compromised immune status. With the rising trend of people afflicted with diabetes mellitus globally, this fulminating infection may pose a serious threat to the medical fraternity. A high index of suspicion and abdominal CT scan usually helps to establish the diagnosis at an early stage and thereby facilitating aggressive antimicrobial therapy and percutaneous drainage where indicated...

The aim of this study was to explore whether the size of paddocks affected social interactions within a group of horses. Furthermore, the effects of the gender composition in groups on social behavior were investigated. The research was done in a horse-riding center. A total of 78 horses and ponies, forming 3 groups, were included in the study. The time of the observation was divided into 2 periods. The data obtained from the 1st period (the horses were on relatively small paddocks) and the 2nd period (the paddocks were significantly bigger) were compared...

Amyloid formation of natively folded proteins involves global and/or local unfolding of the native state to form aggregation-prone intermediates. Here we report solid-state NMR structural studies of amyloid derived from wild-type (WT) and more aggressive mutant forms of transthyretin (TTR) to investigate the structural changes associated with effective TTR aggregation. We employed selective 13C-labeling schemes to investigate structural features of β-structured core regions in amyloid states of WT and two mutant forms (V30M and L55P) of TTR...

BACKGROUND: Previous studies have provided substantial evidence on the association of Aggregatibacter actinomycetemcomitans (Aa), and its highly leukotoxic JP2 genotype, with localized aggressive periodontitis (LAP). The present study aims to evaluate the presence of JP2 in LAP individuals following periodontal treatment. METHODS: Sixty African American LAP patients between ages 5 and 25 years were examined. At baseline, pocket depth (PD), clinical attachment level (CAL), bleeding on probing (BoP) and plaque index were measured and subgingival plaque was collected from both LAP diseased sites and healthy sites for each participant...

Sympathetic ophthalmia (SO) is a rare, diffuse, bilateral, and granulomatous nonnecrotizing panuveitis that may follow intraocular penetrating trauma. Our aim is to report a rare case of SO following orbital exenteration. Orbital exenteration was performed on a 48-year-old african female due to conjunctival keratinizing squamous cell carcinoma with intraocular involvement of the left eye. Five days after the uneventful procedure, the patient presented signs and symptoms compatible with SO. Key differential diagnoses were excluded, and prompt and aggressive immunosuppression was started with a favourable but slow clinical response...

BACKGROUND: Type 1 diabetes mellitus described as a chronic metabolic disorder characterized by aggressive immune β-cell destruction. There are numbers of varied immune mechanisms for sustaining self-tolerance in opposition to the autoimmune disorders. A recessive tolerance accomplished by thymic gland via a negative assortment of different clones while a dominant tolerance accomplished by the regulatory T cells (Treg) in the periphery. Treg (CD4+CD25+FOXP3+) are subsets of T cells which have an essential role in maintaining tolerance...

The clinical course of cerebral cavernous malformations (CCMs) is highly variable. Based on recent discoveries implicating angiogenic and inflammatory mechanisms, we hypothesized that serum biomarkers might reflect chronic or acute disease activity. This single-site prospective observational cohort study included 85 CCM patients, in whom 24 a priori chosen plasma biomarkers were quantified and analyzed in relation to established clinical and imaging parameters of disease categorization and severity. We subsequently validated the positive correlations in longitudinal follow-up of 49 subjects...

Intracranial pure germinomas in children generally respond well to standard chemo-radiotherapy. However, some patients are refractory to standard therapy and require additional treatment. To investigate the characteristics of this subgroup, we retrospectively analyzed the clinical features and treatment outcomes of a cohort of 21 patients with intracranial pure germinomas who were diagnosed between April 2002 and December 2016 at Ehime University Hospital in Japan. Pure germinoma diagnosis was verified by histological examination of the tumor after surgery, and all patients received standard chemo-radiotherapy...

INTRODUCTION: The emergence of extensively drug-resistant tuberculosis (XDR-TB) is a challenging paradigm shift faced by the TB control programs worldwide today. The treatment is further compounded with unique management difficulties faced in pediatric patients. Treatment of XDR-TB requires prolonged chemotherapy with second-line drugs which offer lesser potency and increased risk of drug-related side effects. We present a case of spinal XDR-TB in a child, managed with extended second-line antitubercular chemotherapy (ATT)...

INTRODUCTION: Hemangiomas are benign tumors characterized by proliferation of blood vessels. A few hemangiomas are aggressive, characterized by bone expansion and extraosseous extension. These benign tumors may be mistaken for metatasis resulting in unnecessary biopsies, which have a high risk of hemorrhage. These hemangiomas can spread not just into the paraspinal soft tissues but also into the epidural region of the spinal canal causing cord compression and paraparesis. These clinical symptoms can be relieved by surgical decompression of the posterior elements, embolization or radiotherapy...

B-cell prolymphocytic leukemia (B-PLL) is a rare lymphoid neoplasm with an aggressive clinical course. Treatment strategies for B-PLL remain to be established, and, until recently, alemtuzumab was the only effective therapeutic option in patients harboring 17p deletions. Herein, we describe, for the first time, a case of B-cell prolymphocytic leukemia harboring a 17p deletion in a 48-year-old man that was successfully treated sequentially with idelalisib-rituximab/ibrutinib followed by allogeneic hematopoietic stem cell transplant (allo-HSCT)...

Global gene expression profiling identifies predictive and prognostic biomarkers and rationalizes breast cancer subtype-targeted treatment. The Anthracyclin/Taxol and survival pathway specific small molecular inhibitors, constitute current treatment options. These options are associated with acquired tumor resistance and emergence of drug-resistant cancer stem cells. Dietary supplements and constitutive bioactive phytochemicals with relatively low systemic toxicity may provide testable alternatives for current therapy...

Anevrysmal bone cyst is an aggressive, destructive but benign lesion in the long bones, spine or basin, affecting mainly children and young adults. However, it is a very rare tumor. We here report the case of a 8-year old boy with a very rare localization of anevrysmal cyst in the clavicle, initially presenting with pathologic bone fracture, that is a benign cystic lesion. The child underwent complete radical resection of the cyst located at the level of the right clavicle, followed by anatomopathological examination of surgical specimen which confirmed the diagnosis...

Fibrous tissue proliferations express a wide spectrum of histologic and morphologic variation in both infants and adults. This ranges from hypertrophic scar formation at one end to malignant fibrosarcoma at the other end of the spectrum. Aggressive fibromatosis is an intermediate tumor which is in proximity to fibrosarcomas. These are locally invasive and often recur after excision, but do not metastasize. Histologically, they are characterized by proliferating fibroblasts with little mitotic activity. Aggressive fibromatosis in the head and neck region is not common, and very sporadically occurs in the oral cavity or jaw bones...

Objective: Exosomes are nanovesicles that are released from normal and tumor cells and are detectable in cell culture supernatant and human biological fluids. Although previous studies have explored exosomes released from cancer cells, little is understood regarding the functions of exosomes released by normal cells. Natural killer (NK) cells display rapid immunity to metastatic or hematological malignancies, and efforts have been undertaken to clinically exploit the antitumor properties of NK cells. However, the characteristics and functions of exosomes derived from NK cells remain unknown...
