INTRODUCTION: Duodenal gangliocytic paragangliomas are rare neoplasms often arising in proximity to the major duodenal papilla of Vater. These neoplasms are considered to have a benign behavior with lymph node metastases being a rare phenomenon and distant metastatic disease even more so. Resection of the tumor is the only definitive therapy. PRESENTATION OF CASE: A 67year old male presented to a referring hospital with symptoms of fatigue and malaise. Evaluation with CT imaging revealed a 3...

BACKGROUND: Ureteric colic is the most common symptom of lithiasis. It is caused by the presence of stones accumulated in the renal papillae. These stones often migrate down the ureter, causing a ureteric colic, characterized by a severe pain in the lumbar region. The aim of this study was to compare the use of ketorolac and nifedipine vs. ketorolac and tamsulosin for the medical treatment of pain caused by stones in the lower ureter. METHODS: Longitudinal study of 150 patients of 21-years or older with stones in the lower third of the ureter...

Morphea, or localized scleroderma, is an inflammatory disease that leads to sclerosis of the skin and underlying tissues due to excessive collagen deposition. Oral involvement is unusual and it may produce white linear fibrotic areas with a scar-like appearance, atrophy of tongue papillae, gingival recession and alveolar bone resorption. We report a case of a 13-year-old girl who consulted for progressive recession on the attached gingiva of her upper left incisors. She also presented a hypopigmented line on the left side skin of her upper lip, which continued through the vermilion and the lip mucosa, including the gingiva of the affected teeth...

Taste bud type II cells fire action potentials in response to tastants, triggering non-vesicular ATP release to gustatory neurons via voltage-gated CALHM1-associated ion channels. Whereas CALHM1 regulates mouse cortical neuron excitability, its roles in regulating type II cell excitability are unknown. Here, we compared membrane conductances and action potentials in single identified TRPM5-GFP-expressing circumvallate papillae type II cells acutely isolated from wild-type (WT) and Calhm1-knockout (KO) mice...

Teeth undergo postnatal organogenesis relatively late in life and only complete full maturation a few years after the crown first erupts in the oral cavity. At this stage, development can be arrested if the tooth organ is damaged by either trauma or caries. Regenerative endodontic procedures (REPs) are a treatment alternative to conventional root canal treatment for immature teeth. These procedures rely on the transfer of apically positioned stem cells, including stem cells of the apical papilla (SCAP), into the root canal system...

In this prospective study, 15 patients received 15 variable-thread tapered implants placed in fresh extraction sites in the maxillary esthetic zone and immediately were provisionalized out of occlusion. Of the 15 patients, 11 completed their 2-year follow-up. At 2 years, the success and cumulative survival rates were both 100%, and the mean bone level gain was 0.83 mm. Soft tissue assessment showed no zero esthetic scores, improved papilla indices, and low bleeding on probing and plaque accumulation. Overall, the study implants showed excellent hard tissue, soft tissue, and esthetic outcomes, indicating a healthy tissue response in single-tooth extraction sites in the maxillary esthetic zone...

Primary wound closure and uneventful early wound stability over the biomaterials are the most critical elements of successful periodontal regeneration. Yet the surgical elevation of the interdental papilla to access deep and wide intrabony defects entails an impairment of the papillary blood supply that can result in difficult healing due to a lack of primary closure in the early healing period. This negative event might complicate the healing process, favoring bacterial contamination. A novel modified tunnel surgical technique designed to maintain the integrity of the interdental papilla is presented in this article, with the aim of providing an optimal environment for wound healing in regenerative procedures...

The tongue is an elaborate complex of heterogeneous tissues with taste organs of diverse embryonic origins. The lingual taste organs are papillae, composed of an epithelium that includes specialized taste buds, the basal lamina, and a lamina propria core with matrix molecules, fibroblasts, nerves, and vessels. Because taste organs are dynamic in cell biology and sensory function, homeostasis requires tight regulation in specific compartments or niches. Recently, the Hedgehog (Hh) pathway has emerged as an essential regulator that maintains lingual taste papillae, taste bud and progenitor cell proliferation and differentiation, and neurophysiological function...

Endogenous dermal stem cells (DSCs) reside in the adult hair follicle mesenchyme and can be isolated and grown in vitro as self-renewing colonies called skin-derived precursors (SKPs). Following transplantation into skin, SKPs can generate new dermis and reconstitute the dermal papilla and connective tissue sheath, suggesting they could have important therapeutic value for the treatment of skin disease (alopecia) or injury. Controlled cell culture processes must be developed to efficiently and safely generate sufficient stem cell numbers for clinical use...

Digital dermoscopy (DD) follow up is a useful strategy for monitoring patients at high risk of melanoma. Reflectance confocal microscopy (RCM) is a valuable second-level examination after dermoscopy for the evaluation of difficult to diagnose lesions. The aim of this study was to assess the value of RCM in routine DD monitoring of patients at high risk of melanoma. In this prospective study, performed over 22 months, changing melanocytic lesions were detected by DD and excised. RCM imaging was performed before surgical excision of all the lesions, and histopathology used as the gold standard diagnostic test...
