Hypocomplementaemic urticarial vasculitis: successful treatment with cyclophosphamide-dexamethasone pulse therapy

Systemic hypocomplementaemic urticarial vasculitis unresponsive to several immunosuppressive and immunomodulatory drugs was seen in two women aged 43 and 45 years. Cyclophosphamide-dexamethasone pulse therapy was started in both patients and resulted in significant clinical improvement. The pulse treatment was well tolerated in both patients and no major adverse effects occurred. These cases indicate that cyclophosphamide-dexamethasone pulse therapy is efficient in the treatment of hypocomplementaemic urticarial vasculitis.     

Chronic urticaria associated with aseptic meningitis: an atypical urticarial vasculitis?

OBJECTIVE: This study is based on promising results using the ratio of free/ total (F/T) prostatic-specific antigen (PSA) for discrimination between benign prostatic hypertrophy and prostate cancer. We tried to determine the value of F/T PSA in different clinical situations at a certain time point during follow-up of luteinizing-hormone-releasing hormone (LH-RH) agonist treatment and to correlate it to T-PSA. PATIENTS AND METHODS: 182 patients followed-up for different periods in the last 3 years were routinely monitored for serum T-PSA. During the last 11 months, F-PSA was also measured together with T-PSA, and the ratio of F/T PSA was calculated. In 26 patients, the ratio of F/T PSA was monitored sequentially in several samples. RESULTS: Although 5 patterns of clinical response to LH-RH agonists were identified according to previous T-PSA, the F/T ratio could significantly (p < 0.05) discriminate between patients responding to treatment in contrast to patients escaping, fluctuating or not responding to hormonal ablation. Those patients responding to hormones showed a higher F/T PSA ratio (36.5 +/- 33.1%) compared to the nonresponding group (12.0 +/- 10.1%). CONCLUSIONS: During individual follow-ups, the pattern of response to LH-RH treatment is reflected by the F/T PSA ratio: while successful treatment causes an F/T PSA increase, relapse is accompanied by a decrease in this ratio. However, the changes in the F/T PSA ratio did not precede the indicative changes in T-PSA. It seems that increased values of F/T PSA ratios are intrinsic features of 'benign' prostatic disease, and the molecular events resulting in different PSA molecules in various clinical situations have to be elucidated.     

Maculopapular and urticarial eruption from cetirizine

Cardiac hydatid cyst is a rare parasitic disease. Since it may be associated with fatal complications, early diagnosis and treatment of a cardiac hydatid cyst is very important. We present a case with hydatid cyst localized in the right atrium and bilaterally in the lungs, and embolized pulmonary arteries bilaterally. The right atrial cyst localized on the interatrial septum was removed using cardiopulmonary bypass and the cyst in the right pulmonary artery was extracted by an embolectomy catheter. The patient died of pulmonary hypertension and pulmonary insufficiency three months postoperatively.     

Botulism after intake of half-fermented fish

From 1975 to 1997, 21 cases of foodborn botulism have been reported in Norway. Half-fermented fish is the major cause. We describe one patient with botulism following intake of home-prepared half-fermented fish. Seven people had eaten fish from the same bucket, but only two developed symptoms. The fish was initially stored at 13 degrees C; this probably explains why toxin developed. Type E toxin in moderate concentrations was found in fish samples. The patient was treated with specific antitoxin and made a gradual recovery. He returned to work after eight months.     

Cutaneous granulomatous vasculitis after herpes zoster infection showing polyarteritis nodosa-like features

The coral or Madrepororia is a sea invertebrate with a skeleton morphologically and chemically very similar to mineral bone. In 1990 we implanted coral blocks, sterilized by gamma irradiation, into the nasal dorsa of ten dogs. Resorption and substitution with bone or fibrous tissue were observed within 6 months. Between 1991 and 1994 biocoral was used in 20 patients with saddle nose deformities in order to augment the nasal pyramid and dome. Two extrusions were observed in the early postoperative period during follow-up. One of these extrusions was related to trauma and necessitated removal of the implant. Our findings show that coral is a suitable alloplastic material that can be used in the correction of saddle nose deformities.     

Small vessel vasculitis and vasculitis confined to skin

Cutaneous vasculitis is a heterogeneous group of disorders, which can be confined to the skin or may be part of an associated systemic disease. Various aetiological agents as well as conditions that mimic skin vasculitis, usually present with similar clinical features; mainly palpable purpura. The skin biopsies usually show leukocytoclastic vasculitis. This poses a great diagnositc and therapeutic challenge for the physician. The aetiologies, clinical features, diagnosis and treatment modalities for each form (drugs, infections, malignancies, systemic vasculitides, connective tissue disorders. Sch?nlein-Henoch purpura, cryoglobulinaemia, cutaneous periarteritis nodosa, livedoid vasculitis, erythema elevatum diutinum and urticarial vasculitis) are reviewed.     

Pulmonary vasculitis

Pulmonary vascular inflammation may be seen in a variety of primary lung diseases and in the setting of numerous systemic illnesses. This article reviews those entities in which pulmonary vasculitis represents a central feature of the pathologic process (Wegener's granulomatosis, Churg-Strauss syndrome, and pulmonary capillaritis). In addition, features of pulmonary involvement in other systemic vasculitides (Giant Cell Arteritis, Takayasu's Arteritis, and Beh?et's disease) are described. Finally, general principles for the treatment of vasculitis are reviewed.     

Sustained dapsone-induced remission of hypocomplementemic urticarial vasculitis--a case report

Hypocomplementemic urticarial vasculitis (HUV) is often misdiagnosed. The response to drug therapy may be unsatisfactory, and immunosuppressive therapy may be associated with significant side effects. A 35-year-old patient whose condition was resistant to cyclophosphamide, corticosteroids, pentoxyphylline, cyproheptadine, sulindac, and colchicine was maintained in remission with dapsone, which may be the drug of choice for HUV. Emphysema has been reported to complicate HUV, but this is the first account of vasculitis-related emphysema with no confounding history of tobacco smoke exposure. The relationship of proteolytic injury to the pulmonary and other manifestations is considered, as is the possible role for dapsone in reducing it.     

Proactive interference and temporal context encoding after diazepam intake

Two experiments were designed to test whether the memory impairment induced by benzodiazepines (BZDs) is due to impaired memory for temporal context. In both experiments, subjects were administered either diazepam (15 mg oral) or placebo, and a standard BZD impairment on prose recall as well as a decreased subjective arousal was found. Key tasks to explore temporal context memory were an A-B A-C proactive interference paradigm and a list discrimination task. Initial learning of both groups on these tasks was broadly matched. In experiment 1, diazepam did not increase susceptibility to proactive interference using semantically related words. However, in experiment 2, using unrelated word pairs, diazepam markedly increased the number of prior list intrusions. Furthermore, after diazepam intake, subjects were clearly impaired in learning unrelated word pairs. Subjects after diazepam intake were not impaired in the list discrimination task. We conclude that (1) diazepam impairs the forming of new associations, whether this is the formation of links between two or more targets or between targets and context, (2) a temporal context encoding deficit cannot account for a broader diazepam-induced memory impairment.     

Optic disk vasculitis

A 44-year-old woman developed progressive loss of vision associated initially with a swollen optic disk, and later with optic atrophy and a diffuse retinal vasculopathy, which caused extensive retinal hemorrhagagic. Histopathologic examination showed hemorrhagagic infarction of the retina, as well as infarction of the anterior optic nerve. In the optic nerve, the central retinal vessels showed extensive phlebitis and occlusion of many small arterioles.     

Systemic necrotizing vasculitis

The revival of interest in systemic necrotizing vasculitis was initiated by the discovery of its association with anti-neutrophil cytoplasmic antibodies (ANCA). The close association of certain ANCA subspecificities, for example, proteinase 3 (Pr3) and myeloperxoidase ANCA, with Wegener's granulomatosis, microscopic polyangiitis and Churg-Strauss syndrome has led to their designation as 'ANCA-associated vasculitides'. This article describes the common and divergent clinical and immunological features of the members of this 'new' family of systemic necrotizing vasculitis, which continues to grow with the widespread use of ANCA testing. In addition, the 'standard' treatment for systemic necrotizing vasculitis (daily 'low dose' cyclophosphamide plus glucocorticosteroids or 'Fauci's scheme') is compared with new stage and activity adapted therapeutic regimens.
