Cutaneous Vasculitis in Cogan's Syndrome: A Report of Two Cases Associated with Chlamydia Infection.

Cutaneous Vasculitis in Cogan's Syndrome: A Report of Two Cases Associated with Chlamydia Infection. J Nippon Med Sch. 2018;85(3):172-177 Authors: Kawasaki Y, Uehara T, Kawana S Abstract Cogan's syndrome (CS) is defined by the combination of hearing loss, vertigo, and ocular inflammation of uncertain cause, and can be associated with variable vessel vasculitis. Vasculitic manifestations may include arteritis (affecting large, medium or small arteries), aortitis, and aortic and mitral valvulitis. Cutaneous manifestations including erythema, papules, subcutaneous nodules, and purpura sometimes occur; however, to date, only six cases have been histologically confirmed to have genuine vasculitis. Here, we report two cases of CS, one of which involved a patient who developed the typical symptoms of Takayasu arteritis and purpuric lesions in the legs, with histologic findings consistent with small vessel vaculitis in the dermis. The second case involved a patient who developed subcutaneous nodules in the legs and the axilla, and histologic findings revealed a necrotizing vasculitis of the small arteries in the interlobular area. Both cases were successfully treated with systemic steroid therapy. Based on the clinical features and the examination data, there is a possibility that a Chlamydia trachomatis infection played a pivotal role in the pathogenesis of those vasculitides.

We report a case of a 7-year-old boy with Kawasaki disease (KD) complicated with cerebral vasculitis and encephalitis. The patient was admitted with signs of encephalopathy, seizures, and coma. The diagnosis of KD was made on the 2nd day of hospitalization based on the clinical features (fever >5 days, maculopapular rash, nonpurulent conjunctivitis, fissured lips, and cervical adenopathy). Brain magnetic resonance imaging findings suggested cerebral vasculitis. Treatment with intravenous immunoglobulin was followed by mild improvement. After a single dose of immunoglobulin, pulse methylprednisolone therapy was started ...

We describe a 24-year-old man with CD who showed an abrupt decline in renal function after administration of UST. Twenty-nine months previously, the patient was diagnosed with CD, and abnormal urinalysis findings in health checkup were coincidentally found at that time. Three mont hs previously, treatment for CD was switched from infliximab to UST because of therapy-resistant severe diarrhea and bloody stools. A single dose of UST (260 mg) was initially intravenously administered, followed by single subcutaneous administration (90 mg) 2 months later. Thereafter, the patien t exhibited rapid renal dysfunction...

CONCLUSIONS: In this cohort the most frequent damage item was renal and was related to the disease itself. Damage score was higher in patients with more severe disease and treated more aggressively. Our results suggest that more effective treatment options are needed in a subgroup of patients with IgA vasculitis to prevent the damage related with the vasculitis, especially with more severe disease.

Empirical gonorrhea treatment at initial diagnosis reduces onward transmission. However, increasing resistance to multiple antibiotics may necessitate waiting for culture-based diagnostics to select an effective treatment. There is a need for same-day culture-free diagnostics that identify infection and detect antimicrobial resistance. We investigated if Nanopore sequencing can detect sufficient Neisseria gonorrhoeae DNA to reconstruct whole genomes directly from urine samples. We used N. gonorrhoeae-spiked urine samples and samples from gonorrhea infections to determine optimal DNA extraction methods that maximize the amo...

Authors: Shi R, Luo Y, Li S, Kong M, Liu X, Yu M, Wu J, Huang L, Yang Z Abstract Background: Kawasaki disease (KD) is an acute systemic vasculitis of unknown etiology. Cyclophilin A (CypA), also known as PPIA, has been identified to play a vital role in the pathogenesis of cardiovascular or inflammatory diseases. However, no studies have examined the relationship between single-nucleotide polymorphisms (SNPs) in the peptidylprolyl isomerase A (PPIA) and the development of KD and KD with or without coronary artery lesions (CALs).Objective: The present study was conducted to evaluate whether PPIA SNPs are associated ...

Conclusion: Ocular manifestations were observed in some patients positive for serum ANCAs. Serum ANCA evaluation is useful for identifying the etiology of ocular inflammation and for diagnosing AAV, a life-threatening disease. PMID: 32078414 [PubMed - as supplied by publisher]

Vestibular failure or hypofunction can be generated by pathologies such as vestibular neuritis (VN), causing the onset of rotatory vertigo and the vestibulo-ocular reflex (VOR) hyporeaction. VN is a post-viral inflammation-producing vestibular nerve-axon impairment, which reaches compensation in 70% of cases. Here, we present two cases of vestibular failure that did not respond to pharmacological therapy, but did show modulated vestibular response after an osteopathic manipulative treatment. Dizziness handicap inventory (DHI) was used to assess disability, while VOR was examined by means of video head impulse test (v-HIT).
