[Systemic varicella-zoster infection during ixazomib-containing multiagent chemotherapy for multiple myeloma].

A 58-year-old man received high-dose melphalan with autologous peripheral blood stem cell transplantation for multiple myeloma in stringent complete response (sCR). Relapse occurred 4 years after the transplantation, and he was placed on ixazomib, lenalidomide, and dexamethasone (IRd) and achieved sCR. On the 10th day of the 10th course of IRd, he developed fever followed by generalized skin eruption with vesicles, headache, and dizziness. Varicella-zoster virus (VZV) antigen from the vesicle and VZV-DNA from the cerebrospinal fluid were detected, and he was diagnosed with systemic VZV infection. He was placed on intravenous acyclovir (ACV), and the infection resolved completely. VZV infection has been recognized as an important complication associated with the use of proteasome inhibitors; however, to our knowledge, there have been no reported cases of serious systemic VZV infection associated with ixazomib. The clinical course of this case strongly suggests the importance of prophylaxis for VZV infection during treatment with ixazomib.

Spectrum of purpura fulminans: report of three classical prototypes and review of management strategies.

Purpura fulminans is a rare syndrome of intravascular thrombosis and hemorrhagic infarction of the skin that is rapidly progressive and is accompanied by vascular collapse and disseminated intravascular coagulation. It usually occurs in children, but this syndrome has also been noted in adults. The three forms of this disease are classified by the triggering mechanisms. We describe three classical cases of purpura fulminans of the three classical prototypes treated at our center and their varied clinical outcomes. We also describe a case of acute infectious purpura fulminans secondary to systemic leptospirosis which to our best knowledge is the first reported case in world literature. The various treatment options for purpura fulminans have also been reviewed.

[Varicella-associated purpura fulminans and deep vein thrombosis: a pediatric case report]. / Purpura fulminans post-varicelleux et thrombose veineuse : à propos d'un cas pédiatrique.

Purpura fulminans (PF) and deep vein thrombosis are rare complications secondary to chicken pox disease. The presence of antibodies reflects an ongoing immunological process and requires specialized management. The present study reports a 4-year-old boy with no medical history who presented with purpura on the legs 10 days after chicken pox eruption. Laboratory tests showed a disseminated intravascular coagulation associated with low plasma protein C and S activities, and the presence of anti-protein S antibodies. A replacement therapy with protein C infusions and fresh frozen plasma was prescribed. The patient also underwent regular sessions of hyperbaric oxygen followed by the surgery. Fourteen days after the beginning of the purpuric lesions, he presented deep vein thrombosis (DVT) of the lower limbs and was treated with unfractionated heparin. This case report illustrates the pathophysiology of DVT occurring in a patient with chicken pox disease (i.e., acquired protein C and S deficiencies and anti-protein S autoantibodies) and emphasizes the utility of thrombophilia testing in order to better adapt treatment.

Estudio exploratorio prospectivo de cohortes sobre el tratamiento de la varicela, con homeopatía y tratamiento sintomático / Exploratory prospective cohort study about the treatment of chicken pox, with homeopathy and with symptomatic treatment

Introducción: Existen grandes dificultades para realizar ensayos clínicos con homeopatía, por lo que persiste la controversia sobre su eficacia. No se ha analizado nunca el impacto de la homeopatía sobre la evolución de la varicela. Pacientes y métodos: Estudio exploratorio prospectivo de cohortes. Se efectuó un seguimiento de 160 niños menores de 15 años en tres grupos de tratamiento: homeopatía (grupo1), tratamiento sintomático (grupo 3) o tratamiento mixto (grupo 2). El seguimiento de los sujetos se efectuó hasta el final de la clínica, se contabilizó el número de lesiones en el tronco y se analizó la evolución de los síntomas, como fiebre, picor, malestar, alteración del sueño, apetito y cefalea. Resultados: El grupo tratado con homeopatía tenía una edad mayor (de 5,6 años, frente a 4,2 años en el grupo 3). No hubo diferencias en la presencia de fiebre, picor y número de lesiones en la visita en el momento del diagnóstico. En el grupo tratado con homeopatía, respecto al que recibió tratamiento sintomático, se observó una menor duración de la fiebre (1,4 frente a 2,4 días), de las lesiones de rascado (1,4 frente a 1,8 días) y de las lesiones (6,6 frente a 9,2 días), sin modificarse el resto de las variables. Conclusiones: En este estudio exploratorio y observacional, el tratamiento homeopático indica un beneficio potencial en la reducción de la sintomatología y en la duración de la varicela (AU)

Introduction: It is difficult to carry out clinical trials with homeopathy, and therefore the controversy about its efficiency continues. There is no description, so far, about the impact of homeopathy on chicken pox. Patients and methods: Exploratory prospective cohort study. Follow up on 160 children less than 15 years of age in three groups treated with homeopathy (group 1), conventional treatment (group3) or both (group 2). The subjects where followed up until the end of convalescence. These were Number of skin lesions on the thorax, and evolution of symptoms as fever, itching, discomfort, sleep disorder, hunger and headache was analyzed. Results: The group treated with homeopathy had an age older than (5.6 years vs. 4.2 yrs in group 3), with no differences in the presence of children with fever, itching and number of lesions at the first visit. In the group treated with homeopathy, respect to the one that received symptomatic treatment there was a significant lower duration of fever (1.4 vs. 2.4 days), less length of the scratching lesions (1.4 vs. 1.8 days) and in the duration of the lesions (of 6.6 in the group treated with homeopathy and 9.2 days in the symptomatic group), without any modification in the rest of the variables. Conclusions: In this exploratory observational study the homeopathic treatment indicates a possible benefit in reducing the symptoms and the duration of the chicken pox (AU)

Acute arterial thrombotic purpura complicating varicella and the role of hyperbaric oxygen as an adjunctive therapy.

Chickenpox is a common infectious disease of the pediatric age group with rare complications such as hemorrhagic varicella and arterial thrombotic purpura. Medical support is the mainstay of treatment in such cases but for the rescue of necrotic tissues, hyperbaric oxygen (HBO) therapy should be applied in addition to anticoagulant intervention. We report an infant with acute arterial thrombotic purpura which developed after varicella eruption and who made full recovery with the help of HBO as an adjunctive treatment modality. Fresh frozen plasma and low molecular weight heparin were given for prolonged prothrombin time and thromboemboli on the 2nd-4th digits of his right foot. Protein C, protein S and factor V levels were found to be normal in our patient. Necrotic lesions on the toes regressed with repeated HBO treatment and amputation was not needed.

Postherpetic ophthalmic neuralgia.

Postherpetic ophthalmic neuralgia is the final stage of a varicella zoster infection. Many years after chickenpox infection, patients can develop herpes zoster in one or more specific dermatomal regions. The ophthalmic branch of the trigeminal nerve and the thoracic nerves are most commonly affected. Younger patients are less prone to postherpetic neuralgia than the older. Patients with a depression in cell-mediated immunity are more susceptible to develop postherpetic pain. Postherpetic ophthalmic neuralgia is a neuropathic pain and can be treated by anticonvulsants and tricyclic antidepressants. Neurodestructive procedures are not recommended as they enhance destruction and neuropathic pain. Sympathetic nerve blocks can be helpful. Neurostimulation is the last therapeutic resort.

Acute disseminated encephalomyelitis: clinical and MRI study from South India.

Clinical and MRI appearances were reviewed in 25 cases of acute disseminated encephalomyelitis (ADEM) seen in a university hospital in South India. Specific viral infections and Semple antirabies vaccination together accounted for 56% of antecedent events. Clinical and MRI features were suggestive of diffuse/multifocal form in 15 patients. Of the 10 patients with clinically site restricted forms, two patients with dorsal myelitis and one patient with polyradiculitis had asymptomatic cerebral white matter lesions. MRI was essentially normal in all the four patients with acute ataxia following varicella infection. Of the 13 patients with multiple white matter lesions, lesions were asymmetrical in size and morphology in nine patients and symmetrical in four patients. Two of them had extensive destructive lesions and one patient had multiple discrete lesions. Lesions occurred at the corticomedullary junctions in seven patients. The distribution was subcortical and/or centrum semiovale in 10 patients. The regions affected include internal capsule(s), thalami, brainstem, cerebellar peduncles and cerebellum. No specific differences were observed in patients with ADEM following specific viral infections, Semple antirabies vaccination, and nonspecific upper respiratory tract infections. There was fairly good correlation between clinical and MRI findings in 81% of patients. Patients with incomplete recovery showed extensive and/or multifocal lesions.

Group A streptococcal necrotizing fasciitis complicating primary varicella: a series of fourteen patients.

We retrospectively reviewed the clinical course of group A Streptococcus necrotizing fasciitis complicating primary varicella in children admitted to Children's Hospital and Medical Center, Seattle, WA, during a 18-month period. The potential benefit of various therapeutic interventions was examined. Fourteen children ages 6 months to 10 years were treated for group A Streptococcus necrotizing fasciitis as a complication of primary varicella. Eight patients experienced a delay in initial diagnosis as a result of nonspecific, early clinical findings of necrotizing fasciitis. Each patient underwent surgical exploration with fasciotomies and debridement. Initial antibiotic therapy was broad spectrum and included clindamycin. Hyperbaric oxygen therapy for as many as 6 treatments was used as adjunctively therapy in 12 patients, with subjective benefit in 6 patients. All 14 patients were discharged home with good function and no long term sequelae. This potentially fatal bacterial infection of the deep fascial layers requires early recognition by primary care physicians and an intensive, multidisciplinary therapeutic approach, including thorough surgical debridement and appropriate antibiotic therapy.
