OBJECTIVES: HHV-8, also known as Kaposi's sarcoma (KS) associated herpesvirus is involved in KS and other tumors comprising multicentric Castleman disease (MCD) and primary effusion lymphoma (PEL). Rituximab is currently used for treatment of several autoimmune or inflammatory diseases and humoral organ rejection. De novo HHV-8 induced tumors by rituximab used for autoimmune or inflammatory diseases or humoral organ rejection have not been reported. METHODS: In this retrospective study, we report clinical, virological and pathology of five HIV-negative male patients with HHV-8-induced tumors following rituximab therapy...

Tumor necrosis factor (TNF)-α inhibitors target TNF-α to effectively treat autoimmune inflammatory conditions, such as rheumatoid arthritis. However, many cases of cutaneous and systemic vasculitis related to TNF-α inhibitors have been reported in the literature. Here, the authors report the first case of a 61-year-old Japanese woman who developed leukocytoclastic vasculitis with cutaneous perivascular hemophagocytosis, which was related to elevated cytokines and immune complexes after initiating adalimumab for rheumatoid arthritis without evidence of hemophagocytic syndrome and rarely encountered in the skin...

Hidradenitis suppurativa (HS) is a chronic and debilitating inflammatory skin disease that disproportionately affects women of childbearing age. Yet, little has been written about the impact of pregnancy on the natural history of HS. It has been postulated that apocrine-gland activity diminishes in pregnancy, accounting for symptom remission.

Skin diseases associated with inflammation or oxidative stress represent the most common problem in dermatology. The present study demonstrates that fish scale collagen peptides (FSCP) protect against CoCl2-induced cytotoxicity and TNF-α-induced inflammatory responses in human HaCaT keratinocyte cells. Our study is the first to report that FSCP increase cell viability and ameliorate oxidative injury in HaCaT cells through mechanisms mediated by the downregulation of key proinflammatory cytokines, namely, TNF-α, IL-1β, IL-8, and iNOS...

INTRODUCTION: Nasolabial cutaneous flaps have been routinely used to reconstruct intraoral defects. The purpose of this study was to study histological changes that may occur in the skin flap as a result of its exposure to a new environment. PATIENTS AND METHODS: Thirteen patients took part in this study. Fusiform tissue specimens were obtained from the intraoral cutaneous portion of the flap. Biopsy specimens were also taken from the skin of nasolabial region and from the buccal mucosa to serve as control...

Dermatomyositis or polymyositis as a paraneoplastic syndrome of hepatocellular carcinoma (HCC) is an uncommon event. Few cases have been reported in the literature. We herein report the case of a 55-year-old man with chronic hepatitis B and alcoholism who presented with skin rash. Abdominal computed tomography revealed multiple hypervascular liver tumors consistent with HCC. He subsequently developed dysphagia with proximal limb weakness. Laboratory tests and electromyography demonstrated inflammatory myopathy...

BACKGROUND: Isolated polypoid changes of the middle turbinate were recently reported as having a high association with inhalant allergy. A more advanced manifestation of this association may present as polypoid changes of the entire central sinonasal compartment (i.e., the middle and superior turbinates, and the posterosuperior nasal septum), while the lateral sinus mucosa remains relatively normal. OBJECTIVE: To introduce and describe this newly recognized variant of chronic rhinosinusitis (CRS), termed central compartment atopic disease (CCAD)...

A surgical suture is a medical device to close the wound site of skin and organs but excessive inflammation surrounding the suture can disrupt the wound healing process. Although post-operative prescription of anti-inflammatory drugs is used to manage the inflammation, the need for local drug delivery systems has been rising because of low bioavailability and fast clearance of drugs. In this work, we proposed a new strategy for a local anti-inflammatory device by incorporating macrophage-targeted anti-inflammatory nanoparticles into the suture...

Sutures penetrate tissues to close wounds. This process leads to inflammatory responses, prolongs healing time, and increases operation complexity. It becomes even worse when sutures are applied to stress-sensitive and fragile tissues. By bonding tissues via forming covalent bonds, some medical adhesives are not convenient to be used by surgeons and have side effects to the tissues. Here egg albumen adhesive (EAA) is reported with ultrahigh adhesive strength to bond various types of materials and can be easily used without any chemical and physical modifications...

An onset of acne, a common inflammatory skin disease, is associated with excess sebum production and secretion in sebaceous glands. Because Propionibacterium acnes has been reported to augment intracellular sebum accumulation in sebaceous glands in hamsters, it remains unclear whether P. acnes influences sebum secretion from differentiated sebocytes. Both P. acnes culture media (Acnes73-CM) and formalin-killed P. acnes (F-Acnes73) dose-dependently increased the extracellular levels of triacylglycerol (TG), a major sebum component, and Rhodamine 123, a substrate of adenosine triphosphate-binding cassette (ABC) transporter, from differentiated hamster sebocytes (DHS)...

Endocan is a novel human endothelial cell-specific molecule and is mainly expressed in endothelial cells in various tissues. Endocan has the capacity to inhibit leukocytes binding to the vascular endothelium. It also can promote the angiogenesis alongside vascular endothelial growth factor A. Through these functions, endocan has been implicated in the pathogenesis of various inflammatory diseases. To investigate the possible roles of endocan in atopic dermatitis (AD), we examined endocan expression in lesional skin and sera in patients with AD...

High mobility group protein B1 (HMGB1) has been reported to serve important roles in various pathological conditions. Toll‑like receptor 4 (TLR4), as one of the HMGB1 receptors, has been reported to be involved in the development of certain inflammatory diseases by activating nuclear factor NF‑κ‑B (NF‑κB). However, there are few studies investigating the effects of HMGB1, TLR4 and NF‑κB on human inflammatory dermatoses. In the present study, the distribution and characteristics of HMGB1, TLR4 and NF‑κB p65 expression in psoriasis and atopic eczema (AE) were investigated...

Cutaneous leishmaniasis (CL) is an infectious disease caused by various species of leishmania protozoan parasites. Lupoid CL is a rare form of CL that has a stunning similarity to other granulomatous cutaneous conditions of infectious or inflammatory origin. Verruca plana, also known as a "flat wart", is a benign proliferation of the skin resulting from infection with human papilloma virus (HPV). Herein, we presented a case of lupoid CL mimicking verruca plana on the face.

Radiosynoviorthesis is used for local treatment of recurrent joint effusions, leads to necrosis of inflamed synovium due to beta radiation energy served after intraarticular radionuclide administration. The aim of the therapy is destruction and fibrosis of abnormal, hypertrophic synovial membrane and then full recovery of its normal function after local corticosteroids and systemic modifying drugs failure. Radiosynoviorthesis is effective in different type of peripheral arthritis like rheumatoid arthritis, inflammatory spondyloarthtropaties, gout, chondrocalcinosis, pigmented villo-nodular synovitis, recurrent knee effusion after total joint replacement, idiopathic knee joint effusion, osteoarthritis and secondary prevention of intraarticular bleeding in haemophilia...

Inflammatory bowel disease (IBD) with its 2 most common entities, ulcerative colitis and Crohn's disease, causes an increased risk of developing intestinal cancers. In fact, malignancies are the second most common cause of death after cardiovascular diseases in both sexes of patients with IBD. Risk factors for colorectal cancer in IBD correlate with the duration of the disease, extent of disease, the association with primary sclerosing cholangitis, family history, and early age at onset. Patients with IBD also have an increased risk for developing a variety of extraintestinal malignancies...

BACKGROUND: The 1,2-decanediol (S-Mal) is an organic compound belonging to the 1,2- alkanediol family, with two hydroxyl groups located on the first and second carbon of the alkane chain, probably responsible for the enhanced anti-bacterial efficacy. The willow bark total extract (W-Mal) has been used since thousands of years as an herbal remedy for its antipyretic, analgesic, anti-inflammatory and anti-microbial activities. S-Mal is used in cosmetic preparations, whether W- Mal can be topically or systemically administered...

Scleroderma refers to an autoimmune connective tissue fibrosing disease, including three different subsets: localized scleroderma, limited cutaneous systemic sclerosis, and diffuse cutaneous systemic sclerosis with divergent patterns of organ involvement, autoantibody profiles, management, and prognostic implications. Although systemic sclerosis is considered the disease prototype that causes cutaneous sclerosis, there are many other conditions that can mimic and be confused with SSc. They can be classified into immune-mediated/inflammatory, immune-mediated/inflammatory with abnormal deposit (mucinoses), genetic, drug-induced and toxic, metabolic, panniculitis/vascular, and (para)neoplastic disorders according to clinico-pathological and pathogenetic correlations...

In the search for improved quality of life, the treatment of skin diseases like psoriasis (hyperproliferative disease) is valid, since it causes huge social discomfort to the patient. In this context, earlier studies showed that Malva sylvestris L. has anti-inflammatory activity demonstrated by acute animal models of skin inflammation, becoming a promising target for further studies. The present investigation aimed to verify the effect of hydroalcoholic extract of M. sylvestris (HEMS) on the chronic inflammatory and hyperproliferative response caused by multiple applications of 12-O-tetradecanoylphorbol-13-acetate (TPA) on mouse ears...

Inflammatory preconditioning is a mechanism in which exposure to small doses of inflammatory stimuli prepares the body against future massive insult by activating endogenous protective responses. Phospholipase A2/5-lipoxygenase/leukotriene-B4 (PLA2/5-LOX/LTB4) axis is an important inflammatory signaling pathway. Naja sputatrix (Malayan spitting cobra) venom contains 15% secretory PLA2 of its dry weight. We investigated if Naja sputatrix venom preconditioning (VPC) reduces surgical brain injury (SBI)-induced neuroinflammation via activating PLA2/5-LOX/LTB4 cascade using a partial frontal lobe resection SBI rat model...

Atopic dermatitis (AD), the most prevalent inflammatory skin disease, is characterized by robust T-cell activation. The disease has several subtypes, all having a common T helper type 2 (Th2)/Th22 polarization, but it also displays differential immune skewing, such as increased Th17/interleukin 23 skewing in the skin of intrinsic, Asian, and early pediatric AD patients. Current systemic treatments for moderate to severe AD are largely unsatisfactory, associated with significant adverse effects and low compliance...
