Importance: Adult laryngotracheal stenosis (LTS) is typically managed surgically, but some patients fail treatment because of rapid restenosis or granulation tissue formation. The need for frequent surgery or tracheostomy reduces the quality of life in these patients and poses a significant challenge for the treating physician. New adjuvant treatments are required to reduce the surgical burden of this condition. Objective: To examine whether patients with rapidly recurrent nonvasculitic LTS who fail surgical management of their stenosis (ie, requiring dilation more frequently than every 6 months) experience longer intervals between surgical procedures when receiving adjuvant treatment with low-dose methotrexate...

BACKGROUND: Recent studies have shown an increasing incidence of herpes zoster (HZ) infection, which may be related to the introduction of varicella vaccination programs in children. We examined the epidemiology and treatment costs of HZ and post-herpetic neuralgia (PHN) over time in British Columbia, Canada. METHODS: The cohort consisted of all cases with HZ infection from January 1, 1997 and December 31, 2012. Incident zoster was defined as a case (ICD-9 053 or ICD-10 B02) without a previous episode of HZ or PHN in the previous 12 months...

Vaccination with attenuated live varicella zoster virus (VZV) can prevent zoster reactivation, but protection is incomplete especially in an older population. To decipher the molecular mechanisms underlying variable vaccine responses, T- and B-cell responses to VZV vaccination were examined in individuals of different ages including identical twin pairs. Contrary to the induction of VZV-specific antibodies, antigen-specific T cell responses were significantly influenced by inherited factors. Diminished generation of long-lived memory T cells in older individuals was mainly caused by increased T cell loss after the peak response while the expansion of antigen-specific T cells was not affected by age...

Leukemia cutis develops in <4% of all acute leukemias. Concurrent acute myeloid leukemia (AML) and Langerhans cell histiocytosis (LCH) is rare, with most cases involving lymph nodes or spleen, and no cutaneous involvement. We report the case of a 59-year-old man who presented with fever, malaise, and fatigue. The CBC showed leukocytosis (30.4 × 10/L, 9% blasts), anemia, and thrombocytopenia. Bone marrow biopsy was diagnosed with AML, not otherwise specified, with mutations of FLT3 and IDH2 (R140Q). The patient developed skin rash on the right flank with the clinical differential diagnosis of herpes simplex virus or varicella-zoster virus infection/reactivation versus leukemia cutis...

OBJECTIVES: Beside the determination of oligoclonal bands (OCBs) as a diagnostic biomarker in multiple sclerosis (MS), the presence of an intrathecal production of antibodies against the neurotropic viruses measles (M), rubella (R) and Varicella-Zoster (Z), the so called MRZ reaction (MRZR) is an even more specific diagnostic biomarker in MS. METHODS: We compared and validated the determination of the MRZR in 97 cerebrospinal fluid (CSF) and serum sample pairs of a bead-based multiplexing technique and a classical enzyme-linked immunosorbent assay (ELISA)...

We present the case of a 23 year old with acute onset left hemiparesis and meningeal irritation, associated with recent history of chickenpox 15 days prior. Varicella-IgG and IgM was positive in the CSF and blood along with reduced serum/CSF ratios of VZV immunoglobulins. MRV showed thrombosis (CVT) of superior sagittal, transverse, right sigmoid sinuses with haemorrhagic infarct in right frontoparietal region. Patient responded well to intravenous heparin, Acyclovir and oral anticoagulant therapy.

Ramsay Hunt Syndrome (RHS) is a rare complication of latent varicella-zoster virus (VZV) infection that can occur in immunocompetent host. It usually involves ipsilateral facial paralysis, ear pain and facial vesicles. Disseminated herpes zoster is another complication of VZV infection typically seen in immunocompromised hosts. We describe a patient with relapsed chronic lymphocytic leukemia (CLL) who presented simultaneously with RHS and disseminated herpes zoster. While other complications have been documented to coexist with RHS, to our knowledge, this is the first reported case in the literature of concurrent RHS with disseminated herpes zoster...

Laboratory tests for herpes zoster (HZ) are required to confirm varicella zoster virus (VZV) infection, especially when a skin lesion is not typical or apparent. The serological test for VZV IgM antibody is simple and cost-effective; however, the change in the VZV IgM-positive rate over the time course of the disease has not been investigated. Therefore, we conducted an observational study to evaluate the positive rate of VZV IgM results during the time course of HZ and estimate the VZV IgM-positive period...

The present study investigated the association between radical prostatectomy (RP) and the risk of herpes zoster (HZ). Male patients aged ≥ 40 years and diagnosed with prostate cancer (PCa) between 2000 and 2005 were included in this study. Patients who underwent RP for the first time during 2000-2006 were included in the RP group. Randomly selected individuals from among the remaining patients with PCa who did not undergo RP were included in the non-RP group. Univariate and multivariate Cox regression models were used to analyze the association between PCa and HZ...

Primary Varicella Zoster Virus infection is a benign self-limited disease. In this study, we aimed to review our experience with focusing on the outcome and treatment of the varicella zoster virus (VZV) infection in pediatric malignancy patients. During the study period; a total of 41 patients with pediatric malignancy had been hospitalized with the diagnosis of VZV infection. All the patients were treated with intravenous acyclovir for a median of 7 days (ranging from 5 to 21 days). The calculated attributable delay of chemotherapy due to VZV infections was 8 days (ranging from 2 to 60 days)...

Cycloadditions of N-substituted C-(diethoxyphosphoryl)nitrones to N-allylated quinazoline-2,4-diones functionalized at N3 with substituted benzoyl or benzyl groups proceeded with moderate to good diastereoselectivities (d.e. 28-68%). The synthesized isoxazolidine phosphonates were assessed for the antiviral activity against a broad range of DNA and RNA viruses. Compounds trans-13c, cis-13c/trans-13c (86:14), cis-15b/trans-15b (87:13) and trans-15d/cis-15d (95:5) exhibited the highest activity toward both TK(+) and TK(-) VZV strains (mean EC50 values in the range of 3...

Ill or immunosuppressed hospital patients are at increased risk for herpes simplex and herpes zoster virus infections, with high potential morbidity and mortality. Here, we present two cases of reactivation of herpes virus infections with delay in diagnosis, with ultimately fatal results. Since these infections are treatable, it is important to keep a high index of suspicion to facilitate early diagnosis and treatment.

BACKGROUND: The Advisory Committee on Immunization Practices recommends a single dose of herpes zoster (HZ) vaccine in persons aged 60 years or older, but the efficacy decreases to zero after approximately 10 years. A booster dose administered after 10 years might extend protection, but the cost-effectiveness of a booster strategy has not been examined. OBJECTIVE: We aimed to determine the optimal schedule for HZ vaccine DESIGN: We built a Markov model to follow patients over their lifetime...
