BACKGROUND: Root canal treatment (RoCT), or endodontic treatment, is a common procedure in dentistry. The main indications for RoCT are irreversible pulpitis and necrosis of the dental pulp caused by carious processes, tooth cracks or chips, or dental trauma. Successful RoCT is characterised by an absence of symptoms (i.e. pain) and clinical signs (i.e. swelling and sinus tract) in teeth without radiographic evidence of periodontal involvement (i.e. normal periodontal ligament). The success of RoCT depends on a number of variables related to the preoperative condition of the tooth, as well as the endodontic procedures...

Osteopetrosis is a rare bone disease caused by metabolic imbalances as a result of genetic mutations. For instance, autosomal dominant osteopetrosis is caused by a missense mutation of the C1CN7 gene. This was first reported in 1904 and is thought to be caused by osteoclastic dysfunction and an impaired bone resorption ability. An accumulation of cortical bone mass during the remodeling of the medullary bone may increase the bone density and give rise to a hard marble consistency. Osteopetrosis can be divided into benign and malignant forms; however, no curative treatment exists for benign osteopetrosis...

Fusarium infection is a severe fungal infection caused by fungi of the genus Fusarium. It most commonly occurs in immunocompromised patients with malignant hematological comorbidities or secondary to hematopoietic stem cell transplant. The classical route of contamination is through inhalation but infection may also occur through contiguity with a skin lesion. This report describes the case of a 24-year-old woman who developed graft-vs.-host disease (GVHD) at 220 days after receiving an allogeneic stem cell transplant from a sibling donor for Hodgkin disease...

OBJECTIVE: There is increasing evidence supporting the role of platelets in atherosclerotic vascular disease. The G-protein-coupled receptor P2Y12 is a central mediator of platelet activation and aggregation but has also been linked to platelet-independent vascular disease. Ticagrelor is an oral P2Y12 antagonist that is used as a standard treatment in patients after acute myocardial infarction. However, the effects of ticagrelor on advanced atherosclerosis have not been investigated. MATERIALS AND METHODS: Twenty-week-old apolipoprotein-E-deficient mice received standard chow or standard chow supplemented with 0...

A 50 year-old man on immunosuppressive agents presented with left eye vision loss, periorbital swelling, pain, and ophthalmoplegia. The patient was clinically found to have a central retinal artery and vein occlusion. A CT scan was performed which demonstrated intraorbital fat stranding, however the patient lacked sinus disease. The etiology of the orbital infection was held in question. The area was debrided in the operating room, and the specimen demonstrated group A streptococcal species consistent with necrotizing fasciitis...

During the preoperative diagnostics of an 80-year-old male patient prior to a planned endarterectomy, an unclear space-occupying lesion was detected in the right nasopharyngeal cavity. It proved to be a dense soft tissue space-occupying lesion of the right maxillary sinus. The histological investigations revealed a partially necrotically decomposed malignant tumor below normal respiratory mucosa free from dysplasia. This case demonstrates the difficulties in differential diagnostics, particularly involving (aberrant) expression of cytokeratin...

BACKGROUND: Although retrograde peri-implantitis (RPI) is not a common sequela of dental implant surgery, its prevalence has been reported in the literature to be 0.26%. Incidence of RPI is reported to increase to 7.8% when teeth adjacent to the implant site have a previous history of root canal therapy, and it is correlated with distance between implant and adjacent tooth and/or with time from endodontic treatment of adjacent tooth to implant placement. Minimum 2 mm space between implant and adjacent tooth is needed to decrease incidence of apical RPI, with minimum 4 weeks between completion of endodontic treatment and actual implant placement...

UNLABELLED: An 11-year-old female patient was referred with a chief complaint of pain in the right mandibular second premolar. Clinical and radiographic examinations showed secondary caries under an old composite restoration, a negative response to a pulp test and an immature root with an open apex. After root canal cleaning and shaping, bleeding was invoked in the canal up to 2 mm short of the cemento-enamel junction (CEJ). After 10 min to allow clotting at this level, a plug of Biodentine was placed over the blood clot and the tooth was temporized with glass ionomer cement...

AIMS: Atherosclerosis is the most common cause of cardiovascular diseases, such as myocardial infarction and stroke. We hypothesized that nagilactone B (NLB), a small molecule extracted from the root bark of Podocarpus nagi (Podocarpaceae), suppresses atherosclerosis in an atherosclerotic mouse model. METHODS AND RESULTS: Male apoE-deficient mice on C57BL/6J background received NLB (10 and 30 mg/kg) for 12 weeks. Compared with the model group, NLB treatment (10 and 30 mg/kg) significantly reduced en face lesions of total aorta areas...

INTRODUCTION: The endodontic failure is a common problem in dentistry. The success of endodontic and re-endodontic treatment depends on many factors. These includes periodontal disease, root fractures, residual necrotic pulp tissue, presence of peri-radicular infection, broken instruments, mechanical perforations, root canal underfillings, root canal overfillings, missed canals or unfilled canals. AIM: The present research was aimed at evaluating the different factors responsible for endodontic treatment failure in permanent dentitions of the patients...

Pyogranulomatous rhinitis associated with an algal infection was diagnosed in a 25-year-old gelding and a 23-year-old mare had necrotizing sinusitis with intralesional algae and pigmented fungi. Algae were identified immunohistochemically in both cases as Prototheca spp. In the gelding, further characterization by polymerase chain reaction and sequencing revealed that the organism was Prototheca zopfii genotype 2. Fungi from the mare were identified as Pithomyces chartarum by molecular analysis. Prototheca species are achlorophyllous algae and P...

Kikuchi-Fujimoto's disease (KFD) is a rare, benign condition characterized by histiocytic necrotizing lymphadenitis predominantly in the cervical region and prolonged fever. It has a higher prevalence in the Japanese and Asian populations although it may be seen in a wide geographic distribution, but rare are the cases reported in Europe. While symptoms resolve spontaneously between 2 weeks and 2 months, complications are described in: CNS, eyes, respiratory tract, kidney and liver. KFD also described an association with systemic lupus erythematosus...

Nine Humboldt penguins ( Spheniscus humboldti ), between 1 and 1.5 years old and kept at Zoo Dresden, developed local and systemic infections with various opportunistic pathogens within a period of 4 months. Affected birds died peracutely without preceding symptoms or showed various clinical signs, including separation from conspecifics, reduced food intake, lethargy, dyspnea, swelling of the salt glands, and ocular discharge. One bird showed central nervous signs, including seizures. Pathologic examination of deceased birds revealed severe necrotizing inflammation of the mucous membranes and deep structures of the glottis, trachea, nasal sinus, and conchae and granulomatous inflammation of the salt glands...
