Auto‐immune diseases are a major health problem in both developed and developing countries: They cause as many deaths as the leading infectious diseases and exact an even greater toll on patients’ quality of life given their chronic nature (Box 1). Reliable data for all auto‐immune diseases are hard to collect, but a 2011 study by the American Autoimmune Related Diseases Association (AARDA) reported that the total annual cost of just seven leading auto‐immune diseases (Crohn's disease, ulcerative colitis, systemic lupus erythematosus (SLE), multiple sclerosis (MS), rheumatoid arthritis (RA), psoriasis, and scleroderma) was somewhere between US$51.8 billion and US$70.6 billion in the USA alone (http://www.diabetesed.net/page/_ files/autoimmune-diseases.pdf). The AARDA report also drew attention to the indirect societal toll with one example being sufferers from RA in the USA, who experienced a decline in average earnings from US$18,409 to US$13,900 per year, and the number of jobs they were able to perform dropped from 11.5 to 2.6 million. It was also found that approximately 50 percent of RA patients were unable to work at all within ten years after disease onset. ### Box 1: Some common auto‐immune diseases #### Graves’ Disease The most common auto‐immune disease in which the body produces antibodies to the receptor for thyroid‐stimulating hormone (TSH). It usually attacks the thyroid, frequently causing it to enlarge to twice its size or more (goiter) and become overactive, with related hyperthyroid symptoms such as increased heartbeat, muscle weakness, disturbed sleep, and irritability. No ideal cure but it can be controlled, with last resort surgical excision of the gland. Other treatments include anti‐thyroid drugs, which reduce the production of thyroid hormone, and radioiodine to shrink the gland and reduce its activity. #### Hashimoto's thyroiditis Another auto‐immune disease of the thyroid gland that involves a variety of cell‐ and antibody‐mediated immune processes. It was the first disease to be recognized as auto‐immune in 1912. In this case, the …

Hemangiomas of the jaw bones in children are extremely rare, but can have severe adverse effects.The goal. The purpose of this paper was to draw attention to the diagnostic problems of hemangiomas in children with coagulopathy problems, especially bone ones. Materials and methods. A special case of hemangioma of the mandible, in an adolescent with coagulation pathology, is presented. Results. The literature review and the present case found many identical problems, but also diagnostic and treatment peculiarities. Conclusion. Mandibular bone hemangiomas are rare vascular formations. The diagnosis of hemangiomas in children is difficult because of the rare incidence, treatment peculiarities, as well as because of hidden clinical signs. The general examination is necessary for all forms of hemangiomas and especially for those localized in the jaw bones. Coagulopathy problems greatly complicate the choice of treatment methods. Drug treatment is the favorable option of all treatment options at the present time. Choosing the right treatment method is an important moment in the prevention of side effects.

The Radiologic Diagnosis and Treatment of Typical and Atypical Bone Hemangiomas: Current Status

Plasma cell myeloma (PCM) is a malignant clonal disease of abnormal proliferation of plasma cells, which is the second most common hematological malignancy after leukemia. PCM often diffuses and involves the bones of the whole body, especially the spinal column, ribs, skull, pelvis, and other axial bones and flat bones. Herein, we present a 55-year-old man who came to the hospital seeking medical help for low-back pain and numbness in his lower limbs. Computed tomography (CT) was performed because the clinician suspected that the patient had a herniated disc, and the results showed that the 7th thoracic vertebrae and the 3rd lumbar vertebrae showed a low density of bone destruction with “honeycombing” changes. Magnetic resonance imaging (MRI) showed that the corresponding lesions presented long T1 and long T2 signals, and the lesions were significantly enhanced in contrast-enhanced T1WI sequences, and fluoro18-labeled deoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) showed mild radioactive uptake in the lesions. Based on these imaging findings, the patient was considered for a diagnosis of hemangiomas, and surgery was performed because the affected vertebra was pressing on the spinal cord. However, intraoperative frozen section examination showed that the patient had plasma cell myeloma. Our case study suggests that PCM involving a single thoracic and lumbar spine is rare and should be considered as one of the imaging differential diagnoses of hemangiomas. Moreover, the diagnosis of PCM is difficult when the number of lesions is small, especially when the plasma cell ratio is within the normal reference range in laboratory tests.

ABSTRACTThe decrease of peritubular capillaries, a pathological feature of acute kidney injury (AKI), is a critical part that promotes the transition of AKI to chronic kidney disease (CKD). Ginsenoside Rb1 (Rb1) has various pharmacological effects on multiple systemic diseases. However, whether Rb1 delays the transition of AKI to CKD and the mechanism are unclear. Here, we discovered that Rb1 could alleviate kidney pathological damage in mice with unilateral ischaemia/reperfusion injury (uIRI), and it enhanced kidney function, reduced renal fibrosis while increasing microvessel density. By virtual screening and molecular docking approaches, we identified vascular endothelial growth factor receptor 2 (VEGFR2) as the principal molecular target of Rb1. Furthermore, we uncovered that Rb1 activated AKT phosphorylation‐mediated angiogenesis through binding to VEGFR2, which promoted endothelial tube formation and nitric oxide (NO) release in human umbilical vein endothelial cells (HUVECs) and then relieved the endothelial dysfunction induced by hypoxia‐reoxygenation (H/R). Also, we found that Rb1 activated VEGFR2/AKT signalling in the kidney tissue of uIRI mice. Knocking down VEGFR2 or inhibiting the AKT signalling pathway can impair the proangiogenic effect of Rb1. Taken together, we demonstrated that Rb1 facilitated renal angiogenesis by activating the VEGFR2/AKT pathway of endothelial cells, thereby arresting the transition from AKI to CKD, and providing a potential therapeutic strategy for AKI.

The pathology of the elderly is the direct result of the aging process, aggravated by the physical and mental involution that occurs with advancing age. Age-related eye changes are present, such as: presbyopia, decreased tears, peripheral visual field reduction, vitreous liquefaction (with posterior vitreous detachment and retinal detachment), decreased vision due to cataracts, glaucoma, diabetic retinopathy, macular lesions, Age-Related Macular Degeneration (AMD), optic atrophy. At the same time, there are multiple systemic diseases in the elderly, at the cardiovascular, respiratory, locomotor, neurological, auditory level. The diseases of the elderly can be multiple, with a long, chronic evolution, with periods of exacerbation, frequent complications, prolonged convalescence. Aging is a continuous, dynamic process that must be followed because in its evolution new connections and balances are created that must be identified and treated properly, old age being a distinct stage of ontogenesis that should not be seen as a state of disease. In an elderly patient, the normal aging should be differentiated from pathology.

A multicenter study was undertaken to analyze postoperative wound infections after posterior spinal instrumentation and fusion. The infection rate of these procedures has been documented in multiple reports. From these results, a classification scheme was developed that can guide therapy and determine the populations at risk. The patients were categorized according to two parameters, the first being the severity or type of infection, and the second being the host response or physiologic classification of the patient. This classification scheme is based on the clinical staging system for adult osteomyelitis developed by Cierny. The severity of infection is divided into three groups. Group 1 is a single-organism infection, either superficial or deep. Group 2 is a multiple-organism, deep infection. Group 3 is multiple organisms with myonecrosis. The host response, likewise, is divided into three classes. Class A is a host with normal systemic defenses, metabolic capabilities, and vascularity. Class B patients demonstrate local or multiple systemic diseases, including cigarette smoking. Class C requires an immunocompromised or severely malnourished host. Our data have demonstrated that single organisms, Group 1, generally can be dealt with by single irrigation and debridement, and closure over suction drainage tubes without the use of an inflow-irrigation system. The Group 2 patients, with multiple organisms and deep infection, required an average of three irrigation debridements. They have a higher percentage of successful closures with closed inflow-outflow suction irrigation systems when compared to simple suction drainage systems without constant inflow irrigation. Multiple-organism infections with myonecrosis, Group 3, are exceedingly difficult to manage, and portend a poor outcome. Patients without normal host defenses, Classes B and C, are at high risk for developing postoperative wound infection. Specifically, this study demonstrated that cigarette smoking may be a significant risk factor.

A fibro-osseous lesion is a condition where the regular bone is changed with a fibrous connective tissue matrix that includes an abnormal bone or cementum. These lesions are divided into three groups: ossifying fibroma, cemento-osseous dysplasia (COD), and fibrous dysplasia. COD is the most recurring benign fibro-osseous lesion. These lesions are usually not detected unless infected and are commonly noted accidentally on an X-ray. In this report, we demonstrate a case of periapical cemento-osseous dysplasia in a medically compromised patient with multiple systemic diseases.
