Clinicopathological characteristics of primary gastric T-cell lymphoma

HISTOPATHOLOGY, Issue 6 2009
Kenichiro Kawamoto
Aims:, To investigate the clinicopathological characteristics of 20 primary gastric T-cell lymphoma (GTCL) cases without human T-lymphotropic virus type I infection in Japan, a non-endemic area for coeliac disease. Methods and results:, Fifteen cases had no history of persistent diarrhoea or severe hypoproteinaemia. Histologically, 13 cases (65%) consisted of large cell lymphoma and seven (35%) were of medium-sized cells. Intraepithelial lymphoma cell invasion was found in three cases (15%). Two of 10 surgical cases (20%) showed intramucosal tumour cell spreading with enteropathy-like features. Helicobacter pylori CagA gene was detected in three of 10 cases (30%). The lymphoma cells of all 20 cases were positive for CD3 and/or TCR,F1 and negative for CD56. CD4, and CD8, lymphoma was found in 11 cases (55%), CD4+ lymphoma in seven (35%) and CD8+ lymphoma in two (10%). CD30+, CD5+ and CD25+ lymphomas were detected in nine (45%), 10 (50%) and 11 (55%) cases, respectively. Five-year survival of the 16 available cases was 54%. Early clinical stage and medium-sized cell lymphoma were significantly (P < 0.05) better prognostic factors. Conclusions:, Patients with GTCL exhibit distinct clinicopathological findings and prognoses from those with enteropathy-associated T-cell lymphomas. GTCL may be mainly derived from lamina propria and parafollicular T cells. [source]


Sézary syndrome associated with granulomatous lesions during treatment with bexarotene

BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2006

Summary Sézary syndrome (SS) is a leukaemic variant of cutaneous T-cell lymphoma (CTCL). We report a patient with SS who developed granulomatous lesions. These lesions broke out during treatment with bexarotene when the disease had appeared to stabilize. After a partial clinical remission the disease showed rapid progression and finally led to the patient's death. This contradicts the initial assessment, which considered the granulomatous inflammation as a good prognostic factor in CTCL. [source]


Endothelial dysfunction in glaucoma

ACTA OPHTHALMOLOGICA, Issue 1 2009
Hemma Resch
Abstract. Glaucoma is a group of ocular diseases characterized by optic neuropathy associated with loss of the retinal nerve fibre layer and re-modelling of the optic nerve head, and a subsequent particular pattern of visual field loss. Increased intraocular pressure is the most important risk factor for the disease, but the pathogenesis of glaucoma is not monofactorial. Among other factors, ischaemia and vascular dysregulation have been implicated in the mechanisms underlying glaucoma. The vascular endothelium plays an important role in the regulation of ocular blood flow and pathological alterations of vascular endothelial cells may induce ischaemia and dysregulation. The present review summarizes our current evidence of endothelial dysfunction in glaucoma. This is of interest because endothelial dysfunction is a good prognostic factor for progression in several diseases. Although such data are lacking for glaucoma, endothelial dysfunction may provide an attractive target for therapeutic intervention in open-angle glaucoma and other vascular disorders of the eye.

Clinical Features and Prognosis of Nonepileptic Seizures in a Developing Country

EPILEPSIA, Issue 3 2001
W. Silva
Summary: ,Purpose: To determine the predictive value of clinical features and medical history in patients with nonepileptic seizures (NESs). Methods: One hundred sixty-one consecutive ictal video-EEGs were reviewed, and 17 patients with 41 NESs identified. NES diagnosis was defined as paroxysmal behavioral changes suggestive of epileptic seizures recorded during video-EEG without any electrographic ictal activity. Clinical features, age, sex, coexisting epilepsy, associated psychiatric disorder, social and economic factors, delay in reaching the diagnosis of NES, previous treatment, and correlation with outcome on follow-up were examined. Results: The study population included 70% female patients with a mean age of 33 years. Mean duration of NESs before diagnosis was 9 years. Forty-one percent had coexisting epilepsy. The most frequent NES clinical features were tonic,clonic mimicking movements and fear/anxiety/hyperventilation. The most common psychiatric diagnosis was conversion disorder and dependent and borderline personality disorder. Seventy-three percent of patients with pure NESs received antiepileptic drugs (AEDs), and 63.5% of this group received new AEDs. Fifty-nine percent of the patients received psychological/psychiatric therapy. At follow-up, 23.5% were free of NESs. Conclusions: All seizure-free patients had two good prognostic factors: having an independent lifestyle and the acceptance of the nonepileptic nature of the episodes. Video-EEG monitoring continues to be the diagnostic method to ensure accurate seizure classification. Establishing adequate health care programs to facilitate access to new technology in public hospitals as well as the implementation of continuous education programs for general practitioners and neurologists could eventually improve the diagnosis and treatment of patients with NESs.
