Porphyria cutanea tarda and Sjogren's syndrome

Porphyria cutanea tarda is prevalent in connective tissue disease, common in systemic lupus erythematosus. However, the co-existence of primary sjogren''s syndrome and porphyria cutanea tarda is rare and poses diagnostic and therapeutic challenges. We report a case of porphyria cutanea tarda associated with primary sjogren''s syndrome.     

The predictive value of retinal vascular findings for carotid artery atherosclerosis: are further recommendations with regard to carotid atherosclerosis screening needed?

Vascular retinopathy is the consequence of vascular disease, and the retina is the only place where the arteries can be visualized directly. The purpose of this study was to evaluate the predictive value of retinal vascular findings for carotid artery atherosclerosis. From December 2009 to January 2011, the carotid intima-media thickness (IMT) and total plaque area (TPA) were measured in 179 consecutive patients, who received a fundoscopic examination. The patients were divided into groups as follows: normal retinal artery (normal; n = 44), diabetic retinopathy (DR; n = 25), retinal artery occlusion (RAO; n = 17), retinal vein occlusion (RVO; n = 67), and hypertensive retinopathy (HTN-R; n = 26). The subjects were classified according to the presence of an increased (≥1 mm) IMT and plaque. The values of the mean carotid IMT in the patients with vascular retinopathy (DR, 0.87 ± 0.14 mm; RAO, 1.18 ± 0.47 mm; RVO, 0.84 ± 0.14 mm; HTN-R, 0.90 ± 0.20 mm) were significantly increased compared with those in the normal subjects (0.77 ± 0.13 mm). A total 77 of 135 vascular retinopathy patients demonstrated an increased IMT (57 %), and 97 vascular retinopathy patients had carotid artery plaque (72 %). The relative risk of vascular retinopathy in the prediction of an increased IMT and the presence of plaque was 2.79 and 3.95, respectively. Although The TPA was significantly increased in the patients with RAO (1.87 ± 2.67 cm²) and RVO (0.27 ± 0.23 cm²) compared with the normal subjects (0.18 ± 0.23 cm², all Ps < 0.05), there was no significant difference in the ipsilateral carotid IMT and TPA of the affected eye compared with that of the contralateral eye. In conclusion, vascular retinopathy demonstrated a good predictive value in identifying asymptomatic carotid artery atherosclerosis, and this was not confined to the ipsilateral carotid artery of the affected eye. Further recommendations with regard to carotid atherosclerosis screening in patients with vascular retinopathy should be considered.

Report of 457 sporotrichosis cases from Jilin province,northeast China,a serious endemic region

Background Most reported sporotrichosis cases came from South American countries, the USA, India and Japan. This mycosis is also endemic in Northeast China. However, the situation is not clear for international researchers due to lack of large series reported in English. Objectives To report and analyse 457 sporotrichosis cases. Methods Retrospective study of 457 cases of sporotrichosis diagnosed by fungal culture at the First Hospital of Jilin University from 1 January 2007 to 31 December 2009. Results In this series, the male: female ratio was 1:1.42. Mean age was 41.2 years. Cases from age group 51–60 years accounted for most of the cases (22.54%). A total of 434 patients lived in rural areas (94.97%). The onset of symptoms in 67.61% cases happened in cold seasons (winter and spring). History of trauma presented in 133 cases (29.1%). The mean duration of the symptoms before the presentation was 6.41 months. A total of 190 (41.58%) showed lymphocutaneous form, 252 patients (55.14%) showed fixed form, 8 patients (1.75%) showed disseminated cutaneous sporotrichosis and the clinical form of 7 patients (1.53%) could not be defined. Extremities and nodules were the most frequently involved sites and founded manifestation. Main histopathology findings were suppurative granuloma, tuberculoid granuloma and mixed inflammatory granuloma. A total of 75 cases (19.74%) had fungal elements revealed by Periodic Acid‐Schiff staining. Patients responded well to potassium iodide (KI), itraconazole, terbinafine and combinations of these agents with a mean course of 2.17 months to resolve. Conclusion As the first report of a large series of sporotrichosis cases from China to be published in English literature, our study indicated a serious sporotrichosis endemic situation in Jilin province, Northeast China, with epidemiological and clinical characteristics similar to those of previous Chinese reports, but different from those in other countries. KI, itraconazole and terbinafine are effective for the treatment.     

Preoperative elevation of serum C-reactive protein as an indicator of poor prognosis for early-stage esophageal squamous cell carcinoma

Preoperative elevation of serum C-reactive protein (CRP) is reportedly associated with poor prognosis in several types of cancer. This study investigated the role of serum CRP as a prognostic factor in early-stage esophageal squamous cell carcinoma (ESCC). The preoperative serum CRP levels were measured in 156 newly diagnosed pT1–2N0M0 patients using an enzyme-linked immunosorbent assay. Correlations between serum CRP levels and other clinical parameters were analyzed. Multivariate analyses were performed to find prognostic markers using Cox's proportional hazards model. CRP concentrations were within the normal range in 117 (75%) individuals, but were elevated in 39 (25%) patients. Serum CRP levels were significantly correlated with the tumor length (p = 0.032), depth (T classification, p = 0.0157), or histologic grade (p = 0.034). The overall 5-year survival rates were 76.3% and 50.2% in the low- and high-CRP groups, respectively (p = 0.005). By multivariate analyses, the elevated serum CRP level was found to be an independent prognostic factor for poor survival (hazard ratio = 2.131; p = 0.007), regardless of tumor classification or other prognostic factors. In conclusion, preoperative, high serum CRP is an independent determinant of poor prognosis in early-stage ESCC.
