Trigeminal Trophic Syndrome,Report of Four Cases and Review of the Literature

DERMATOLOGIC SURGERY, Issue 5 2004
Parrish Sadeghi MD
Background. Trigeminal trophic syndrome is a unilateral, frequently crescent-shaped neurotrophic ulceration of the face occurring after injury to the trigeminal nerve. The appearance of the ulcers resembles other disease entities such as granulomatous disease, neoplasm, vasculitis, infection, and factitial dermatitis. Objectives. The objectives of this study are to increase awareness of this disorder and to emphasize the importance of eliciting a thorough neurologic history when evaluating facial ulcerations. Methods. Four cases are reported and, using MEDLINE, the English and non-English literature from 1982 to 2002 is reviewed. Results. Including this report, there have been 60 cases of trigeminal trophic syndrome reported from 1982 to 2002. The age at presentation ranged from 14 months to 93 years. Time of onset from injury to the trigeminal ganglion or its branches and the development of the ulcers ranged from 2 weeks to 30 years. One-third of the patients had undergone trigeminal nerve ablation for the treatment of trigeminal neuralgia and another third had a history of stroke. Other causes included craniotomy, head trauma, herpes infection. Conclusion. The majority of cases of trigeminal trophic syndrome are associated with a history of stroke or trigeminal nerve ablation. Successful surgical outcome can be achieved if the underlying neurologic pathology is addressed before the reconstructive procedure. [source]

Short-term efficacy of tacrolimus ointment and impact on quality of life

PEDIATRICS INTERNATIONAL, Issue 3 2009
Yasuto Kondo
Abstract Background:, Topical calcineurin inhibitor (TCI) was reported to be an effective therapeutic agent for patients with atopic dermatitis (AD), for not only improving clinical findings but also for reducing pruritus. Recently in Japan tacrolimus ointment (0.03%) as a TCI was approved for use in children aged ,2 years. There have been no reports, however, on the impact of TCI on quality of life (QOL) in pediatric AD in Japan. The purpose of the present study was therefore to evaluate the efficacy of tacrolimus ointment (0.03%) in the short-term and the impact on patient QOL. Methods:, A total of 30 pediatric patients with AD, whose skin problems were not sufficiently controlled by mid-high potency topical glucocorticosteroids, were enrolled. Efficacy was assessed on score of cutaneous findings, pruritus, sleeping disorder, and QOL. Results:, Three patients discontinued because of skin burning (n = 1), generalized herpes infection (n = 1), and feeling of lack of efficacy (n = 1), leaving a final total of 27 patients who were evaluated. Significant improvements in clinical findings, pruritus, and sleeplessness were observed within 1 week of treatment and consequently each QOL category was also improved. These improvements continued for the duration of the study. Conclusions:, Tacrolimus ointment therapy is rapidly effective for not only clinical symptoms (cutaneous findings, pruritus and sleeplessness) but also in QOL of AD pediatric patients aged 2 years.

ORIGINAL ARTICLE: Estradiol Limits Viral Replication Following Intravaginal Immunization Leading to Diminished Mucosal IgG Response and Non-sterile Protection Against Genital Herpes Challenge

Citation Gillgrass A, Chege D, Bhavanam S, Kaushic C. Estradiol limits viral replication following intravaginal immunization leading to diminished mucosal IgG response and non-sterile protection against genital herpes challenge. Am J Reprod Immunol 2010; 63: 299,309 Problem, Previously we reported that ovariectomized (OVX) mice receiving estradiol (E) prior to immunization with an attenuated strain of HSV-2 (TK-HSV-2) were not protected. Lack of protection in the E group was because of the inability of TK-HSV-2 to penetrate the thick keratinized epithelium. In this study, we determined the outcome of immunization after the thickening of vaginal epithelium following E-treatment waned. OVX, C57BL/6 mice were given Progesterone (P), E or saline (S) for 3 days and immunized with IVAG TK-HSV-2. Method of study, To determine the time point at which E-treated mice could be successfully immunized, the mice were inoculated with TK-HSV-2 between days 1 and 7 (ED1,ED7) post-E-treatment and challenged with IVAG HSV-2 three weeks later. Results, The level of infection post-immunization correlated with HSV-2-specific IgG antibody level, which correlated with sterile protection. No viral infection was observed in ED1,ED3 groups and no specific antibodies were detected, resulting in no protection. Moderate infection was seen in ED5 group, resulting in low antibody production and non-sterile protection in 87.5% of mice. High antibody titers and sterile protection were observed in all groups that experienced robust infection post-immunization. Conclusion, The results show that estradiol leads to limited viral replication and diminished mucosal IgG response, resulting in non-sterile immune protection against genital herpes infection.

Immunohistological study of infiltrated cells and cytokines in murine herpetic keratitis

ACTA OPHTHALMOLOGICA, Issue 5 2001
Tomoyuki Inoue
ABSTRACT. Purpose: To identify localization and kinetics of infiltrated cells and cytokines in murine herpetic keratitis. Methods: HSV-1 was inoculated onto the scarified BALB/c corneas. At given times post infection (PI), eyes were removed and studied immunohistochemically using monoclonal antibodies against several infiltrated cells and cytokines. Results: Neutrophils and NK cells infiltrated as early as 1 day PI reaching a maximum number at 2 day PI in initial stage. ,, TCR positive cells were observed in the corneal stroma from 1 day PI to 8 day PI. IL-2 and IFN-, were positive in the cell-infiltrated areas of the epithelial and stromal lesions, whereas IL-4 was negative throughout the experiment. Conclusion: Our results indicated that cytokine profile upon herpes infection on the cornea is Th1 dominant. Together with neutrophils in the early phase of infection, ,, positive T cells may play an additional role in protecting the cornea against incoming pathogens. [source]
