1/331. Progressive outer retinal necrosis syndrome as an early manifestation of human immunodeficiency virus infection.Progressive outer retinal necrosis syndrome is a recently recognized variant of necrotizing herpetic retinopathy, developing in patients with acquired immune deficiency syndrome (AIDS) or other conditions causing immune compromise. We report a case in which the diagnosis of retinal necrosis syndrome was made before the diagnosis of AIDS was confirmed. A 41-year-old man presented with a 1-month history of blurred vision in his left eye. Ophthalmologic examination revealed extensive retinal necrosis with total retinal detachment in his left eye and multifocal deep retinal lesions scattered in the posterior fundus as well as in the peripheral retina in his right eye. The serologic test for human immunodeficiency virus (HIV) was positive. Despite intravenous acyclovir treatment for 1 week, the lesions in the right eye showed rapid progression. High doses of intravitreal ganciclovir were then given in addition to intravenous acyclovir. After combined treatment for 1 month, the lesions became quiescent and the visual acuity improved to 20/30. Although the patient soon developed full-blown AIDS, the vision in his right eye remained undisturbed. physicians should suspect progressive outer retinal necrosis syndrome in any patient with rapidly progressive necrotizing retinopathy and test the patient for HIV infection. Aggressive combined antiviral agent therapy should be considered to save vision.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
2/331. herpes zoster. Case report of possible accidental inoculation.A 30-year-old healthy male physician developed grouped, papulovesicular lesions along the dermatomes of T1 and T2 of the left side of his body. The onset occurred two days after he accidentally pricked his right index finger with a needle that had been used to aspirate the acute papulovesicular lesion of a patient with severe herpes zoster. The clinical appearance and dermatomal distribution, the subsequent clinical course, the skin biopsy findings, and the substantial increase in complement-fixing antibody titer to the varicella-zoster (V-Z) virus in the convalescent serum samples are strong evidence for herpes zoster. Although it is generally believed that person-to-person transmission of zoster is rare and that herpes zoster results from the reactivation of a latent varicella virus, the present case suggests that zoster can be acquired from exogenous infection with a V-Z virus, at least in certain circumstances.- - - - - - - - - - ranking = 0.2keywords = infection (Clic here for more details about this article) |
3/331. Cutaneous infections by papillomavirus, herpes zoster and candida albicans as the only manifestation of idiopathic CD4 T lymphocytopenia.BACKGROUND: Selective depletion of CD4 T lymphocytes is common in both primary and secondary immunodeficiencies. Idiopathic CD4 T lymphocytopenia (ICL) cases are defined as a persistent CD4 T lymphocyte count of less than 300x10(6) cells/L and/or less than 20% of the total T-cell count. METHOD: A 40-year-old woman, with a history of psoriasis and paracetamol allergy, presented with persistent warts of the hands and condylomas of the ano-genitalia. Histological and virological analysis was carried out on genital and cutaneous lesions and peripheral blood. RESULTS: serology for hiv-1, hiv-2, Epstein-Barr virus and parvovirus B19 were negative. There was lymphopenia of 10% CD4 cells, with normal numbers of total leukocytes; there were no other-abnormal immunological findings. dna analysis of cutaneous lesions revealed HPV-49 and HPV-3 in the hands and HPV-6 in the genital region. CONCLUSIONS: The cause of the ICL in this patient is unknown. HPV is not known to be an immunosuppressive agent; it remains to be determined whether the HPV-associated lesions are the cause or the result of immunosuppression.- - - - - - - - - - ranking = 0.8keywords = infection (Clic here for more details about this article) |
4/331. herpes zoster in a 7-month-old infant: a case report and review.herpes zoster (HZ) is a cutaneous viral infection of the skin that presents in a dermatomal distribution. It represents reactivation of herpes varicella zoster virus that has continued to exist in a latent form in the neurons of the posterior root ganglia. Although it is rare to see HZ in children, cases have been reported after exposure to varicella zoster in utero or during the first months of life. We present a case of HZ in a healthy 7-month-old girl who had had chickenpox at age 4 months.- - - - - - - - - - ranking = 0.2keywords = infection (Clic here for more details about this article) |
5/331. herpes zoster in seven disparate dermatomes (zoster multiplex): report of a case and review of the literature.Noncontiguous multidermatomal herpes zoster is very rare in both immunocompetent and immunocompromised persons. Most of the reported cases have been limited to 2 noncontiguous dermatomes. This unique presentation has been referred to as zoster duplex unilateralis or bilateralis, depending on whether one or both halves of the body are involved. Granulomatous dermatitis at sites of herpes zoster scars, a rare isotopic response, has only been reported in persons with contiguous dermatomes of zoster. We describe an immunocompromised patient who developed herpes zoster in 7 disparate dermatomes. Three months after resolution of the zoster, the patient developed a granulomatous dermatitis in a zosteriform distribution at the sites of previous infection.- - - - - - - - - - ranking = 0.2keywords = infection (Clic here for more details about this article) |
6/331. Impact of cerebrospinal fluid PCR on the management of HIV-infected patients with varicella-zoster virus infection of the central nervous system.Over a 2 year period, we identified five HIV-infected patients who presented with central nervous system infection caused by varicella-zoster virus, three with myelitits, and two with meningoencephalitis. All five patients were profoundly immunocompromised. Clinical presentation of these patients overlapped to a significant extent with diseases caused by other viruses, e.g. CMV. Indeed, in one case, a dual infection with CMV was diagnosed, but the respective role of each virus was ascertained by in situ hybridisation. At the time of CNS involvement, only one patient had active VZV cutaneous lesions, which were instrumental in diagnosing her condition. In contrast, PCR for VZV dna in the CSF was helpful in making a diagnosis in the four other cases, one of which was confirmed by a post mortem. Of these five patients, two patients developed VZV disease while receiving oral acyclovir and had foscarnet treatment initiated when MRI demonstrated widespread lesions. They did not respond to antiviral therapy. The three other patients had intravenous acyclovir initiated at a time when no or limited parenchymal lesions were observed by MRI. Two of these three patients had VZV infection diagnosed solely on the basis of PCR: all three responded to treatment. Our data show that reactivation of VZV involving the central nervous system occurs frequently in the absence of cutaneous lesions. PCR of cerebrospinal fluid may help in making an early diagnosis which is probably a prerequisite for successful treatment of VZV infection of the CNS.- - - - - - - - - - ranking = 1.6keywords = infection (Clic here for more details about this article) |
7/331. Patient-controlled epidural analgesia for postherpetic neuralgia in an HIV-infected patient as a therapeutic ambulatory modality.A 43-year-old HIV-positive male was referred to our pain clinic one month after his fourth attack of herpes zoster infection. He complained of intermittent intolerable sharp and lancinating pain accompanied by numbness over the inner aspect of the left upper extremity, left anterior chest wall and the back. physical examination revealed allodynia over the left T1 and T2 dermatomes without any obvious skin lesion. The pain was treated with epidural block made possible by a retention epidural catheter placed via the T2-3 interspace. After the administration of 8 ml of 1% lidocaine in divided doses, the pain was completely relieved for 4 h without significant change of blood pressure or heart rate. A pump (Baxter API) for patient-controlled analgesia (PCA) filled with 0.08% bupivacaine was connected to the epidural catheter on the next day and programmed at a basal rate of 2 ml/h, PCA dose 2 ml, lockout interval 15 min, with an one-hour dose limit of 8 ml. He was instructed to report his condition by telephone every weekday. The pump was refilled with drug and the wound of catheter entry was checked and managed every 3 or 4 days. The epidural catheter was replaced every week. During treatment, the pain intensity was controlled in the range from 10 to 0-2 on the visual analogue scale. He was very satisfied with the treatment and reported only slight hypoesthesia over the left upper extremity in the early treatment period. Epidural PCA was discontinued after 28 days. He did not complain of pain thereafter but reported a slight numb sensation still over the lesion site for a period of time. In conclusion, postherpetic neuralgia in an HIV-infected man was successfully treated with ambulatory therapeutic modality of epidural PCA for 28 days.- - - - - - - - - - ranking = 0.2keywords = infection (Clic here for more details about this article) |
8/331. Acute varicella zoster with postherpetic hyperhidrosis as the initial presentation of HIV infection.A 31-year-old man presented with acute pain in his left arm and hemorrhagic vesicles that followed his left 8th cervical nerve. A diagnosis of herpes zoster was made, and the patient was treated with valacyclovir. He refused testing for antibodies to HIV because he denied being at risk. Two months later he returned with postherpetic neuralgia and postherpetic hyperhidrosis in the distribution of the vesicles, which had since resolved. serology for HIV at this visit was positive, and the patient admitted to having sexual relations with prostitutes. Six months later the patient was being treated with triple antiretroviral therapy, and all signs and symptoms of postherpetic zoster had resolved. This case report documents the need for HIV testing in patients with unusual presentations of herpes zoster even if they initially deny being at risk.- - - - - - - - - - ranking = 0.8keywords = infection (Clic here for more details about this article) |
9/331. Simultaneous treatment of cytomegalovirus and varicella zoster infections in a renal transplant recipient with ganciclovir: use of viral load to monitor response to treatment.Disseminated zoster occurring simultaneously with cytomegalovirus (CMV) disease in a renal transplant recipient is potentially life threatening. We describe the use of intravenous ganciclovir to treat both infections. The efficacy of treatment was assessed clinically and by the measurement of CMV viral load using the hybrid capture (Murex version 2) and varicella zoster (VZV) viral load using an in-house assay. Results from this case suggest that clinical resolution in severe viral infections such as described below may be related to early control of viraemia.- - - - - - - - - - ranking = 1.2keywords = infection (Clic here for more details about this article) |
10/331. Following the clues to neuropathic pain. Distribution and other leads reveal the cause and the treatment approach.Neuropathic pain can seem enigmatic at first because it can last indefinitely and often a cause is not evident. However, heightened awareness of typical characteristics, such as the following, makes identification fairly easy: The presence of certain accompanying conditions (e.g., diabetes, HIV or herpes zoster infection, multiple sclerosis) Pain described as shooting, stabbing, lancinating, burning, or searing Pain worse at night Pain following anatomic nerve distribution Pain in a numb or insensate site The presence of allodynia Neuropathic pain responds poorly to standard pain therapies and usually requires specialized medications (e.g., anticonvulsants, tricyclic antidepressants, opioid analgesics) for optimal control. Successful pain control is enhanced with use of a systematic approach consisting of disease modification, local or regional measures, and systemic therapy.- - - - - - - - - - ranking = 0.2keywords = infection (Clic here for more details about this article) |
