Gauzoma in A Scleroderma Patient Following Open Heart Surgery: A Case Report.

INTRODUCTION: Gauzoma is an iatrogenic complication which occurs rarely due to surgical team negligence. Depending on the sterility of the retained tissue, it can lead to life threatening surgical complications or may remain asymptomatic for many years and be detected incidentally in imaging studies. It may be mistaken as tumors or aneurysms. Thus, high clinical suspicion is needed to diagnose them in patients with past history of operation. Reporting Case: A 35 years old woman, a known case of scleroderma underwent open-heart surgery 20 years before being diagnosed as scleroderma, presented by dyspnea especially on activity. The High Resolution CT (HRCT) for evaluating the interestial lung disease was done which detected a 7 cm (in greatest diameter) inflammatory mass in posterior aspect of left hemi thorax with a radiopaque thread in its center. True cut biopsy was done and sent for pathology, which revealed fragments of foreign body materials probably gauze pad fibers with cell debris and blood. CONCLUSION: Here, we highlighted the details in clinical history, CT findings, and pathology report of gauzoma in thorax of a scleroderma patient following previous open-heart surgery. It can be guidance for clinician to consider this diagnosis in patients with past history of operation.

Determinants of unemployment amongst Australian systemic sclerosis patients: results from a multicentre cohort study.

OBJECTIVES: We sought to assess employment status, risk factors for unemployment and the associations of unemployment with patients' health related quality of life (HRQoL). METHODS: All patients enrolled in a systemic sclerosis (SSc) longitudinal cohort study, completed an employment questionnaire on enrolment. Clinical manifestations were defined based on presence at the time of enrolment. Summary statistics, chi-square tests, univariate and multivariable logistic regression were used to determine the associations of various risk factors with employment. RESULTS: Among 1587 SSc patients, 160 (20%) were unemployed at the time of cohort enrolment excluding retired patients. Of these, 63% had limited disease subtype. Mean (±SD) age at enrollment was 51.9 (±10.4) years; 13 years below the average retirement age in Australia. Mean (±SD) disease duration at recruitment was 11.1 (±10.9) years. Multivariable regression analysis revealed the presence of digital amputation (OR 3.9, 95%CI 1.7-9.1, p=0.002), diffuse disease subtype (OR 2.2, 95%CI 1.3-3.5, p-value=0.002), sicca symptoms (OR 2.7, 95%CI 1.6-4.4, p<0.001), a physical job (OR 1.8, 95%CI 1.1-3.1, p=0.03) and pulmonary arterial hypertension (OR 2.2, 95%CI 1.1-4.5, p=0.02) to be associated with unemployment. Unemployed patients had consistently poorer HRQoL scores in all domains (physical, emotional and mental health) of the SF-36 form than those who were employed. CONCLUSIONS: SSc is associated with substantial work disability and unemployment, which is in turn associated with poor quality of life. Raising awareness, identifying modifiable risk factors and implementing employment strategies and work place modifications are possible ways of reducing this burden.

A diffuse sclerosing variant of papillary thyroid carcinoma: clinical and pathologic features and outcomes of 34 consecutive cases.

BACKGROUND: The diffuse sclerosing variant of papillary thyroid carcinoma (DSPC) is a relatively rare variant of papillary thyroid cancer. Large studies of patients with DSPC have been infrequently performed, and controversy still exists concerning some DSPC features and outcomes. The aim of the present study was to retrospectively evaluate the clinicopathologic features and outcomes in a series of 34 consecutive patients with DSPC and to compare them with a larger group of 245 consecutive patients with the classic variant of papillary thyroid carcinoma (cPTC) that were evaluated in the same period. PATIENTS AND METHODS: Clinical and histological features (sex, age, tumor size,multifocality, bilaterality, extra thyroid extension, and local and distant metastases) were recorded in all patients, as well as any persistent or recurrent disease and the patients' disease status at last observation. Patients with cPTC were classified as either low (122) or high risk (123). DSPC and high-risk patients were all treated with the same protocol, including ¹³¹I treatment. All patients were included in a Cox regression model analysis to investigate the effect of each variable on the hazard ratio. RESULTS: As expected, multifocality, bilaterality, and extra thyroid extension were more frequently noted at presentation, and the pT1 category of TNM classification was less frequently noted in DSPC and high-risk patients with cPTC compared with low-risk patients with cPTC. No significant difference was found between patients with DSPC and those with high-risk cPTC, except that extra thyroid extension was found more frequently in the patients with DSPC. Using multivariate analysis, diffuse sclerosing variant was an independent variable for predicting a high risk of persistent and recurrent disease during initial follow-up. However, at a later time, and after further treatment, the disease status was not different between patients with DSPC and those with high-risk cPTC, and only the presence of distant metastases affected the final outcome. CONCLUSIONS: DSPC is a thyroid papillary carcinoma variant characterized by high aggressiveness. In patients with DSPC, the outcome is worse than in patients with low-risk cPTC; and, at presentation, characteristics are somewhat worse than for patients with high-risk cPTC.At medium term, the outcome is similar to that observed in patients with high-risk cPTC, provided aggressive treatment is used (additional surgical intervention, when required, and/or ¹³¹I radiotherapy).

Autologous stem cell transplantation improves microcirculation in systemic sclerosis.

BACKGROUND: In systemic sclerosis (SSc) reduced capillary density decreases blood flow and leads to tissue ischaemia and fingertip ulcers. Nail fold videocapillaroscopy (NVC) is a diagnostic and follow-up parameter useful to evaluate the severity, activity and the stage of SSc microvascular damage. Autologous haemopoietic stem cell transplantation (HSCT) is a new treatment for patients with severe diffuse cutaneous systemic sclerosis (dcSSc) refractory to conventional therapies. We aimed to evaluate the improvement of microvasculature after HSCT using NVC. METHODS: A total of 16 patients with severe dcSSc with a "late" videocapillaroscopy pattern underwent an immunesuppressive treatment: 6 were treated with HSCT and 10 with monthly pulse cyclophosphamide (CYC) 1 g for 6 months and then orally with 50 mg/day for further 6 months. NVC was performed before and after 3 months from the beginning of each treatment and then repeated every 3 months. RESULTS: In all patients, before HSCT NVC showed large avascular areas and ramified capillaries and vascular architectural disorganisation ("late" pattern). At 3 months after HSCT, the NVC pattern changed from "late" into "active", showing frequent giant capillaries (>6/mm) and haemorrhages, absence of avascular areas and angiogenesis phenomena; 1 year after HSCT, microvascular abnormalities were still in the "active" pattern. In patients treated with CYC, no NVC modifications were observed during 24 months of follow-up and the pattern always remained "late". CONCLUSIONS: These results indicate that HSCT with a high dose CYC regimen may foster vascular remodelling, while CYC at lower doses and with a chronic regimen does not influence the microvasculature.

Autologous stem cell transplantation in diffuse scleroderma: impact on hand structure and function.

BACKGROUND: The aim of the study was to assess the structural and functional effects of autologous stem cell transplantation (ASCT) on scleroderma finger clawing. METHODS: Using photocopies of hands of five scleroderma patients who underwent ASCT using photocopies of hands. Functional assessments used a standardized questionnaire. RESULTS: Pre-ASCT, synovitis and tenosynovitis were present in five and four patients, respectively. Modified Rodnan hand skin scores ranged from 6-12/12. Following pulsed chemotherapy, synovitis resolved. Tenosynovitis often did not. Post-ASCT, skin scores fell in four patients (range 0-6/12). Hand tenosynovitis resolved. With disease remission hand function globally improved. Functional improvement, noted early (+3 months) and continuously (+12 months) in disease remitters, occurred in all areas of function. Greatest hand-functional improvement related to paid employment, followed by self-care and hygiene, home-care activities and least by hobbies/sports. The second to fifth metacarpophalangeal width was reproducible and independent of ASCT therapy. In contrast, hand length and measures of abducted finger span (first to fifth fingertip and second to fifth fingertip distance) improved. Finger abduction (abducted first to fifth fingertips/second to fifth metacarpophalangeal width) was a more sensitive discriminator of finger clawing than hand length or hand length/second to fifth metacarpophalangeal width. CONCLUSION: ASCT improved hand scleroderma over 12 months and resolved previously refractory tenosynovitis. ASCT was unnecessary to treat scleroderma synovitis. ASCT secondarily improved hand function (paid employment, followed by self-care, home care, then by sport/hobbies). Loss of finger abduction was a more sensitive measure of finger clawing than apparent loss of hand length.

Capillary regeneration in scleroderma: stem cell therapy reverses phenotype?

BACKGROUND: Scleroderma is an autoimmune disease with a characteristic vascular pathology. The vasculopathy associated with scleroderma is one of the major contributors to the clinical manifestations of the disease. METHODOLOGY/PRINCIPAL FINDINGS: We used immunohistochemical and mRNA in situ hybridization techniques to characterize this vasculopathy and showed with morphometry that scleroderma has true capillary rarefaction. We compared skin biopsies from 23 scleroderma patients and 24 normal controls and 7 scleroderma patients who had undergone high dose immunosuppressive therapy followed by autologous hematopoietic cell transplant. Along with the loss of capillaries there was a dramatic change in endothelial phenotype in the residual vessels. The molecules defining this phenotype are: vascular endothelial cadherin, a supposedly universal endothelial marker required for tube formation (lost in the scleroderma tissue), antiangiogenic interferon alpha (overexpressed in the scleroderma dermis) and RGS5, a signaling molecule whose expression coincides with the end of branching morphogenesis during development and tumor angiogenesis (also overexpressed in scleroderma skin. Following high dose immunosuppressive therapy, patients experienced clinical improvement and 5 of the 7 patients with scleroderma had increased capillary counts. It was also observed in the same 5 patients, that the interferon alpha and vascular endothelial cadherin had returned to normal as other clinical signs in the skin regressed, and in all 7 patients, RGS5 had returned to normal. CONCLUSION/SIGNIFICANCE: These data provide the first objective evidence for loss of vessels in scleroderma and show that this phenomenon is reversible. Coordinate changes in expression of three molecules already implicated in angiogenesis or anti-angiogenesis suggest that control of expression of these three molecules may be the underlying mechanism for at least the vascular component of this disease. Since rarefaction has been little studied, these data may have implications for other diseases characterized by loss of capillaries including hypertension, congestive heart failure and scar formation.
