PURPOSE: Assessment of TTT results in patients with exudative age-related macular degeneration. MATERIAL AND METHODS: The study comprised of 65 patients (73 eyes), in age 50-84 years (average age-75 yrs). The diagnosis of exudative AMD was established on the basis of fundus examination and fluorescein angiography (FA) and in some cases on indocyanine green angiography. The baseline visual acuity (VA) ranged from counting fingers at 50 cm to 0.8. In 31 (42.5%) eyes occult CNV, in 11 (15%) minimally classic CNV and in 31 (42.5%) eyes predominantly classic CNV were observed. Subfoveal CNV was present in 70 (95.9%) eyes and perifoveal in 3 (4.1%). TTT was delivered using a diode laser at 810 nm wavelength, a spot size of 1.2 to 4.5 mm and a duration of 60 seconds for each spot with power settings between 320-800 mW. Follow-up examinations were carried out every 10-12 weeks. In cases with persistent leakage from CNV in late frames of FA a retreatment was performed. The follow-up period ranged from 6 to 28 months (average - 9.8 months). RESULTS: Visual acuity improved in 22 (30.1%) eyes, stabilized in 34 (46.6%) and deteriorated in 17 (23.3%). Fluorescein angiography showed no CNV leakage in 58 (79.5%) eyes. In 56 (71.8%) with regression of leakage in fluorescein angiography improvement or stabilization of visual acuity was detected. Subretinal haemorrhages after TTT were observed in 4 eyes (5.5%). At the end of the follow-up period fibrosis of CNV was detected in 12 eyes (16.4%). CONCLUSIONS: TTT is effective and safe method of treatment of occult and classic CNV in a course of wet AMD. In a majority of cases TTT results in total or partial regression of CNV and stabilization of visual acuity.  相似文献

Helicoidal peripapillary chorioretinal degeneration (HCPD) is characterized by bilateral wing- shaped atrophic areas in retina, radiating from the optic disc. Two cases (women: 23 and 58 years old) of this rare degeneration are presented. No changes of eye fundus and erg, eog, visual field evaluations had been noticed during 2 years follow-up.  相似文献

BACKGROUND: Cheilitis granulomatosa, often regarded as a subtype of orofacial granulomatosis, is characterized by recurrent or persistent swelling of one or both lips. Classically, a non-necrotizing granulomatous inflammation is seen at histologic examination. Although a relationship has been proposed between Melkersson-Rosenthal syndrome (and the monosymptomatic form, cheilitis granulomatosa) and Crohn's disease on the basis of the orofacial swelling and similar histology, several studies of Melkersson-Rosenthal syndrome have not found an association with Crohn's disease. METHODS: The clinical features, histopathology, association with Crohn's disease, and results of nonsurgical and surgical therapy in 13 patients with cheilitis granulomatosa were investigated in a retrospective case study with a mean follow-up period of 8.2 years. RESULTS: There was a low chance of developing Crohn's disease. Most patients in this study responded to nonsurgical treatment modalities. Patients with deterioration of lip swelling usually responded to intralesional injections with triamcinolone or to short courses of systemic glucocorticoids. Nonsteroidal systemic modalities, such as clofazimine, hydroxychloroquine, or sulfasalazine, were alternatives to glucocorticoid regimens, thus avoiding the long-term side effects of corticosteroids. Surgical intervention should only be performed in severely disfiguring cases. CONCLUSIONS: The management of cheilitis granulomatosa remains a challenge. As this study revealed a low chance of developing Crohn's disease, it does not seem justified to inform patients with cheilitis granulomatosa of the possibility that they might develop Crohn's disease. Patients with a negative history of gastrointestinal complaints should not be exposed to routine investigations of the gastrointestinal tract.  相似文献

Background  Lipoprotein (a) [Lp(a)] is a genetically determined molecule whose role has been implied in cardiovascular pathology, and whose levels have been reported to be elevated in patients with psoriasis.
Aim  To assess the serum levels of Lp(a) in patients with psoriasis, and to investigate the associations of Lp(a) with other lipids and with psoriasis severity.
Methods  Thirty-four patients with psoriasis and 26 healthy control subjects took part in the study. Serum levels of Lp(a) and total, high density lipoprotein (HDL), low density lipoprotein (LDL), and very low density lipoprotein (VLDL) cholesterol fractions were measured in all participants. The levels of triglycerides and total cholesterol were measured using enzymatic colorimetric tests; HDL and LDL cholesterol concentrations were determined by precipitation methods; the VLDL concentration was calculated according to the formula: VLDL cholesterol = triglycerides/5.
Results  Patients with psoriasis showed significantly higher serum levels of Lp(a) relative to controls. Even when controlling for normolipidemic vs. hyperlipidemic status, abnormal levels of Lp(a) (> 30 mg/dL) were observed significantly more often in patients than in controls. In both patients and controls, Lp(a) levels correlated positively with total and HDL cholesterol levels. In patients, Lp(a) levels correlated positively with psoriasis severity.
Conclusions  Lp(a) may be a factor contributing to an increased cardiovascular risk in patients with psoriasis. A pathogenetic link may exist between this lipoprotein and psoriatic pathophysiology.  相似文献

Background and aimsCholesteryl ester transfer protein (CETP) and phospholipid transfer protein (PLTP) are crucial proteins in reverse cholesterol transport. There are insufficient data on regulating these proteins by insulin therapy in type 1 diabetes mellitus (T1DM). We aimed to assess prospectively the impact of insulin therapy initiation on transfer proteins serum levels in adults with newly diagnosed T1DM.Methods and results57 adults with newly diagnosed T1DM were enrolled in the InLipoDiab1 Study. All participants were treated with subcutaneous insulin in the model of intensive insulin therapy since the diagnosis of diabetes. Serum PLTP and CETP concentrations were measured at diagnosis, after three weeks, six months, and after one year of insulin treatment, using the immunoenzymatic method ELISA.A significant decrease in PLTP and CETP concentrations were demonstrated during twelve months of insulin therapy in newly diagnosed T1DM. The dynamics of changes in the level of these proteins varied depending on the occurrence of remission after a year of the disease. In the group without remission, a significant decrease in PLTP and CETP levels appeared after six months of follow-up. The remission group was characterized by a decrease in proteins concentration only after one year of treatment. In the non-remission group, significant negative correlations were found between the daily dose of insulin and levels of PLTP and CETP.ConclusionExogenous insulin is an inhibitor of lipid transfer proteins involved in high-density lipoprotein cholesterol metabolism in the first year of treatment.  相似文献

BACKGROUND: Although Helicobacter pylori is a significant etiologic factor of peptic ulcer disease, it remains unknown why ulcers develop only in the minority of infected individuals. AIM: The aim of this cross-sectional study was to evaluate the association between the presence of duodenal ulcer in H. pylori-infected patients and different risk factors. METHODS: A total of 122 H. pylori-infected patients were enrolled; 79 had duodenal ulcer and 43 gastritis. Univariate analysis was conducted using either Fisher's exact test or exact Cochrane-Armitage trend test. In multivariate analysis the logistic model was used. RESULTS: Univariate analysis indicated six factors (male sex, smoking, antral H. pylori density, CAGA presence in antrum, and VACA s1a presence in antrum and corpus). Four factors (sex, smoking-alcohol index, H. pylori density index, and CAGA index) were found to be significant in multivariate analysis. The best model predicting duodenal ulcer included male sex, smoking, presence of H. PYLORI on histopathology in antrum and CAGA presence in corpus. CONCLUSION: Although several risk factors were significantly associated with duodenal ulcer, we failed in the identification of either a single risk factor or a set of factors that can unequivocally differentiate patients with ulcer from those with gastritis.  相似文献
