Programmed death-ligand 1 (PD-L1) expression in cervical intraepithelial neoplasia and cervical squamous cell carcinoma of HIV-infected and non-infected patients.

Programmed death-ligand 1 (PD-L1) is overexpressed in cervical carcinoma, hindering tumor destruction. The aim of this study was to assess PD-L1 expression by immunohistochemistry in cervical squamous cell carcinoma (SCC) and squamous intraepithelial lesions (SILs) from human immunodeficiency virus-positive (HIV+) and human immunodeficiency virus-negative (HIV-) patients. A total of 166 SCC and SIL samples of HIV+ and HIV- patients were included and analyzed for PD-L1 expression through tumor proportion score (TPS), and results were stratified in five TPS groups using SP263 antibody and, combined positive score (CPS) using 22C3 antibody. In cohort 1 (SP263 clone), all HIV+ patients were negative for intraepithelial lesion or malignancy (NILM), and low-grade squamous intraepithelial lesions (LSILs) scored < 1; and 87.5% of high-grade squamous intraepithelial lesions (HSILs) adjacent to SCC, 19% of HSILs non-adjacent to SCC, and 69% of SCCs scored ≥ 1 (15.4% scored 5). In HIV- patients, all NILM, LSILs, HSILs adjacent to SCC, and two HSILs non-adjacent to SCC scored < 1. SCC: 88.2% scored ≥ 1 and 5.9% scored 5. In cohort 2 (SP263 and 22C3 clones), 16.7% of HIV+ patients with SCC were positive with both clones, CPS ≥ 1 (22C3) or score 5 (≥ 50%) (SP263), showing no significant differences in positivity between both clones. These results indicate that a relatively low percentage of SCCs (16.7%; both in HIV+ and in HIV- patients) express PD-L1 (TPS ≥ 50% and CPS > 1), which may be due to some samples being archival material, sample characteristics, or use of different methodologies, highlighting the need for standardization of PD-L1 assessment in SCC of the cervix. The fact that PD-L1 is overexpressed in SILs of HIV+ patients suggests potential additional applications for immunotherapy in this disease.

Asymptomatic chronic red eye: A surgical technique case report.

Introduction and importance: Ocular Surface Squamous-cell Neoplasia (OSSN) is an infrequent diagnosis whose clinical suspicion assumes great importance and should not be overlooked. The following case-report aims to describe the diagnosis and treatment of a patient with OSSN whose complaints were mild in comparison to the severity of the disease. The chosen surgical technique was paramount for a disease-free outcome while minimizing the scarring effects of surgical removal. CASE PRESENTATION: Patient presented mild discomfort right eye and painless persistent hyperaemia. Slit-lamp observation showed a clear diagnosis and lesion's extent evaluated through multimodal imaging. After surgical excision the patient underwent topical ocular treatment with mitomycin-C for a higher margin of safety even before the pathology results were available. DISCUSSION: Ancillary exam technology improvement has allowed a higher margin of safety while determining the extent of OSSN lesions. In the absence of clear diagnostic criteria and guidelines, clinical reasoning and OSSN awareness are critical for timely diagnosis and treatment, as several treatment options are available, allowing an increasing number of patients to be treated non-invasively. In this case-report, we highlight the importance of early-recognition and the reasoning for choosing a combined treatment option with a higher margin of safety. CONCLUSION: Early recognition and prompt treatment of OSSN lesions is of paramount importance to avoid ocular invasiveness and potentially preclude both ocular and systemic complication. The choice of a combined surgical and medical approach may provide a higher margin of safety for suitable cases. This patient is currently disease-free at 6-month follow-up.

Clonal hematopoiesis is not prevalent in Hutchinson-Gilford progeria syndrome.

Clonal hematopoiesis of indeterminate potential (CHIP), defined as the presence of somatic mutations in cancer-related genes in blood cells in the absence of hematological cancer, has recently emerged as an important risk factor for several age-related conditions, especially cardiovascular disease. CHIP is strongly associated with normal aging, but its role in premature aging syndromes is unknown. Hutchinson-Gilford progeria syndrome (HGPS) is an ultra-rare genetic condition driven by the accumulation of a truncated form of the lamin A protein called progerin. HGPS patients exhibit several features of accelerated aging and typically die from cardiovascular complications in their early teens. Previous studies have shown normal hematological parameters in HGPS patients, except for elevated platelets, and low levels of lamin A expression in hematopoietic cells relative to other cell types in solid tissues, but the prevalence of CHIP in HGPS remains unexplored. To investigate the potential role of CHIP in HGPS, we performed high-sensitivity targeted sequencing of CHIP-related genes in blood DNA samples from a cohort of 47 HGPS patients. As a control, the same sequencing strategy was applied to blood DNA samples from middle-aged and elderly individuals, expected to exhibit a biological age and cardiovascular risk profile similar to HGPS patients. We found that CHIP is not prevalent in HGPS patients, in marked contrast to our observations in individuals who age normally. Thus, our study unveils a major difference between HGPS and normal aging and provides conclusive evidence that CHIP is not frequent in HGPS and, therefore, is unlikely to contribute to the pathophysiology of this accelerated aging syndrome.

Lymphocyte Subsets in Cervicovaginal Lavage Specimens of HIV-Infected Women: A Surrogate Risk Marker of HPV-Associated Cervical Lesions.

INTRODUCTION: To better understand the role of mucosa immunity in the development of cervical carcinoma in HIV infection, cervical lymphocyte subsets were characterized in HIV+ and HIV- women, as well as their relation to HPV-associated cervical lesions. METHODS: Eighty-three (52 HIV+, 31 HIV-) cell suspensions of cervicovaginal lavage (CVL) and 52 HIV+ peripheral blood (PB) samples were assessed by flow cytometry to evaluate lymphoid populations. High-risk (HR) HPV was assessed in liquid-based cytology and HIV mRNA in PB in the same patients. RESULTS: Cervical CD4+ T cells and CD4+/CD8+ ratio were decreased (p < 0.0001) and cervical CD8+ T cells were increased (p = 0.0080) in HIV+ women. These patients had lower CD4+ T-cell percentages in CVL compared to PB (p = 0.0257), and the opposite was true for CD8+ T cells (p = 0.0104). They also had a higher prevalence of high-grade squamous intraepithelial lesions (SILs) with an increased prevalence of HR HPV. Cervical CD8+ T cells were increased in HR HPV+ patients (p = 0.0300) and related to higher prevalence of SILs (p = 0.0001). DISCUSSION/CONCLUSION: Cervical lymphoid populations can be characterized by flow cytometry, showing a distinct cervical T-cell compartment in HIV+ women. This may represent a surrogate risk marker of HPV-associated cervical lesions in this population and prompt further research on this subject, contributing to improving patients' management.

In vivo expansion of a CD9+ decidual-like NK cell subset following autologous hematopoietic stem cell transplantation.

Autologous hematopoietic stem cell transplantation (autoHSCT) is a treatment option for hematological disorders and pediatric solid tumors. After an autoHSCT, natural killer (NK) cells are the first lymphocyte subset returning to normal levels. To uncover global changes during NK cell reconstitution after autoHSCT, we performed RNA-sequencing on NK cells before and after autoHSCT. Results showed profound changes in the gene expression profile of NK cells immediately after autoHSCT. Several biological processes including cell cycle, DNA replication and the mevalonate pathway were enriched. Significantly, we observed that following autoHSCT, NK cells acquired a decidual-like gene expression profile, including the expression of CD9. By using multiparametric flow cytometry, we confirmed the expansion of NK cells expressing CD9 immediately after autoHSCT, which exhibited higher granzyme B and perforin expression levels than CD9- NK cells. These results provide insights into the physiopathology of NK cells during their reconstitution after autoHSCT.

Pelvic Desmoid Tumor: A Rare Case with Difficult Diagnosis and Treatment.

Desmoid tumors are rare benign neoplasms, with locally aggressive characteristics. Ongoing or previous pregnancy, antecedent trauma, and familial adenomatous polyposis are known risk factors. Still, the majority of cases are sporadic and its etiology is still unknown. These tumors may occur in any body site, but retroperitoneal and pelvic desmoid tumors are extremely rare. Nonspecific clinical and radiological findings lead to erroneous diagnosis in 50% of patients before surgery. We present a case of a young multiparous female with a deep infiltrative lesion adherent to the right pelvic sidewall leading to severe right hydroureteronephrosis and ipsilateral loss of renal function. Although deep endometriosis was suspected, malignancy features could not be excluded by imaging studies. The patient underwent an exploratory laparotomy for definite diagnosis and treatment, which led to right nephrectomy, hysterectomy, and right oophorectomy because of deep infiltration and difficult dissection. Definite histologic diagnosis revealed the presence of a pelvic desmoid tumor. Positive margins were encountered but, until this moment, no disease relapse occurred.

Estado, comunidades terapêuticas e neoliberalismo: um estudo sobre a política de drogas no Brasil / State, therapeutic communities and neoliberalism: a study on drug policy in Brazil

A partir das mudanças correntes na política de drogas brasileira, que incentivam a expansão de instituições denominadas Comunidades Terapêuticas (CTs) ­ unidades destinadas ao acolhimento de pessoas que fazem uso de drogas ­, tem-se feito cada vez mais necessários estudos sobre o tema. Diante do entendimento de que, para entender a inserção das CTs no Estado, é preciso expandir o olhar e complexificar a questão, identificamos a importância de uma discussão que aborde o modo de funcionamento do neoliberalismo em seus vieses de organização estatal e social. Por essa razão, este trabalho tem como objetivo ­ por meio de um estudo qualitativo e documental ­ identificar as afinidades entre o avanço da racionalidade neoliberal e a lógica de funcionamento das Comunidades Terapêuticas no Brasil. Para isso, trabalhamos com os fundamentos políticos do neoliberalismo, entendendo-o como uma racionalidade política que altera todos os aspectos da vida; identificamos os fundamentos das CTs e a relação dessas instituições com o Estado brasileiro por meio da análise de legislações; e discutimos, partindo da análise documental realizada nos jornais O Globo e Folha de São Paulo e em documentos oficiais, o cenário de alianças, disputas e discursos políticos que, ao se afinarem com os fundamentos neoliberais, possibilitaram a expansão das CTs. No que tange às afinidades encontradas, destacamos dois momentos políticos importantes: o primeiro, ainda sob o mandato de Dilma Rousseff (PT), entre 2011 e 2016, apresenta, principalmente, um discurso pluralista neoliberal aliado à ideia de liberdade negativa e à soberania compartilhada do Estado; o segundo ­ pós-impeachment, em 2016 ­ é de incremento aos fundamentos supracitados com a formação de uma plutocracia em defesa de uma moral conservadora aliada ao discurso de responsabilização individual e ao esvaziamento dos espaços públicos de discussão. Todos os fundamentos encontrados demonstram não só a afinidade entre a expansão neoliberal e as CTs como também o derretimento dos princípios da democracia. A partir desta análise, espera-se que este estudo possa qualificar e dar subsídios para a construção de políticas de saúde de caráter público destinadas a usuários de substâncias psicoativas que se sustentem a partir de uma lógica democrática.

Since the changes in the Brazilian drug policy are stimulating the growth of Therapeutic Communities (TCs) ­ residential units which offer care to drug users ­, studies on the subject prove to be needed. To understand the close relationship between the TCs and public policies, it is necessary to expand our debate, hence we will recognize the importance of a study that analyzes how neoliberalism works. That said, this thesis aims to identify ­ through qualitative study and documental analysis ­ the likeness between neoliberal rationality and TCs' operation. To achieve that, we have discussed the neoliberalism political foundations, understanding it as political rationality that changes the surroundings of life; we have identified the TCs foundations and their connection with the Brazilian legislation; through the documental analysis we have discussed, through the brazilian newspapers O Globo and Folha de São Paulo, as well as official documents, the alliances, disputes, and political discourses that, together with the neoliberal foundations, enabled the growth of TCs. In addition to that, we have highlighted two important political marks. The first ­ situated in Dilma Rousseff's (PT) presidential term (2011-2016) ­ presents a neoliberal pluralist discourse allied with the idea of negative liberty and the shared sovereignty of the State. The second ­ which took place after Dilma's impeachment, in 2016 ­ introduces, in addition to the above foundations, the formation of a plutocracy that defends a conservative morality allied with the discourse of individual accountability and the emptying of public spaces for discussion. All the foundations we found have shown not only the affinity between neoliberal and the TCs growth, but also the undoing of democracy. We expect this discussion to qualify and offer subsidies for the construction of public health policies for drug users that are sustained in democratic foundations.

Detection of HIV mRNA in routine liquid-based cytology specimens of HIV-infected women.

OBJECTIVE: Human immunodeficiency virus-infected women have a high incidence of HPV infection, and HIV and HPV coinfection is associated with high incidence of cervical intraepithelial lesions and cervical cancer. This study investigated the ability to detect HIV mRNA in routine screening cervical liquid-based cytology (LBC) samples and its correlation with HPV coinfection and cervical intraepithelial lesions. METHODS: Liquid-based cytology samples from 80 HIV-infected women under combined antiretroviral therapy (cART) were studied for detection of HIV and HPV mRNA using Aptima® tests and for cytology diagnosis according to the 2014 Bethesda System for Reporting Cervical Cytology. Peripheral blood (PB) HIV mRNAs were assessed by real-time polymerase chain reaction (RT-PCR). Statistical analysis used Fisher's exact or Chi-square test to compare frequencies among groups and the Mann-Whitney U test to compare continuous variables. RESULTS: Human immunodeficiency virus mRNA was present in 21.3% of routine LBC samples in HIV-infected women, 12.5% of which had no detectable PB viral load. Among 10 patients diagnosed with high-grade squamous intraepithelial lesion (HSIL), 50% had detectable HIV viral load. The occurrence of HSIL vs low-grade intraepithelial lesion/negative intraepithelial lesion or malignancy in LBC samples was significantly higher in women with detectable HIV viral load (P = .029). CONCLUSIONS: Human immunodeficiency virus mRNA was present in routine LBC samples in HIV-positive women under cART. Detection of HIV viral load in LBC is significantly associated with cervical HSIL. This suggests the relevance of HIV mRNA viral load assessment in routine LBC, to evaluate patients' infectious potential and monitor efficacy of the cART scheme.

Clonal Hematopoiesis and Risk of Progression of Heart Failure With Reduced Left Ventricular Ejection Fraction.

BACKGROUND: Clonal hematopoiesis driven by somatic mutations in hematopoietic cells, frequently called clonal hematopoiesis of indeterminate potential (CHIP), has been associated with adverse cardiovascular outcomes in population-based studies and in patients with ischemic heart failure (HF) and reduced left ventricular ejection fraction (LVEF). Yet, the impact of CHIP on HF progression, including nonischemic etiology, is unknown. OBJECTIVES: The purpose of this study was to assess the clinical impact of clonal hematopoiesis on HF progression irrespective of its etiology. METHODS: The study cohort comprised 62 patients with HF and LVEF <45% (age 74 ± 7 years, 74% men, 52% nonischemic, and LVEF 30 ± 8%). Deep sequencing was used to detect CHIP mutations with a variant allelic fraction >2% in 54 genes. Patients were followed for at least 3.5 years for various adverse events including death, HF-related death, and HF hospitalization. RESULTS: CHIP mutations were detected in 24 (38.7%) patients, without significant differences in all-cause mortality (p = 0.151). After adjusting for risk factors, patients with mutations in either DNA methyltransferase 3 alpha (DNMT3A) or Tet methylcytosine dioxygenase 2 (TET2) exhibited accelerated HF progression in terms of death (hazard ratio [HR]: 2.79; 95% confidence interval [CI]: 1.31 to 5.92; p = 0.008), death or HF hospitalization (HR: 3.84; 95% CI: 1.84 to 8.04; p < 0.001) and HF-related death or HF hospitalization (HR: 4.41; 95% CI: 2.15 to 9.03; p < 0.001). In single gene-specific analyses, somatic mutations in DNMT3A or TET2 retained prognostic significance with regard to HF-related death or HF hospitalization (HR: 4.50; 95% CI: 2.07 to 9.74; p < 0.001, for DNMT3A mutations; HR: 3.18; 95% CI: 1.52 to 6.66; p = 0.002, for TET2 mutations). This association remained significant irrespective of ischemic/nonischemic etiology. CONCLUSIONS: Somatic mutations that drive clonal hematopoiesis are common among HF patients with reduced LVEF and are associated with accelerated HF progression regardless of etiology.

CD4+ and CD8+ cell populations in HIV-positive women with cervical squamous intra-epithelial lesions and squamous cell carcinoma.

INTRODUCTION: This study aimed to analyse cervical lymphocytic populations in HIV+ and HIV- patients and correlate different cervical lesions with HIV viral load and presence of high-risk HPV types. MATERIAL AND METHODS: A total of 132 histological specimens from 40 HIV+ and 72 HIV- patients were evaluated for CD4+ and CD8+ T cell distribution, presence of high-risk HPV types, peripheral blood HIV viral load and CD4+/CD8+ ratio. RESULTS: High-grade squamous intraepithelial lesions (HSIL) and squamous cell carcinoma (SCC) from HIV+ patients had lower CD4+ T cell scores compared with HIV- patients. In all lesion groups, HIV+ patients presented higher epithelial and stromal CD8+ T cell scores. HIV viral load was more often detectable in patients with SCC than in those with low-grade squamous intraepithelial lesion (LSIL) (p = 0.0409). HSIL HIV+ patients had lower circulating CD4+ T cell counts (p = 0.0434) and CD4+/CD8+ ratio (p = 0.0378) compared with LSIL HIV+ patients. High-risk HPV types other than 16 and 18/45 were more prevalent in the HIV+ group. DISCUSSION: These results support an imbalance between cervical CD4+ and CD8+ T lymphocytes of HIV+ patients with SIL and SCC, with increased CD8+ infiltrate density with lesion severity, even in patients with immune system recovery under cART.

Entre Caps AD e Comunidades Terapêuticas: o cuidado pela perspectiva dos usuários de um Caps AD / Between Caps AD and Therapeutic Communities: care from the perspective of users of Caps AD

RESUMO O debate em torno dos dispositivos e modelos de cuidado destinados aos usuários problemáticos de álcool e outras drogas tem ganhado cada vez mais espaço nas políticas públicas. A partir da discussão sobre os paradigmas da abstinência e da redução de danos, buscou-se investigar as relações e os sentidos que os usuários atribuem a esses paradigmas por meio da utilização das Comunidades Terapêuticas e dos Centros de Atenção Psicossocial Álcool e Drogas. Para isso, utilizou-se a metodologia da entrevista semiestruturada com usuários da rede de saúde mental que já haviam utilizado ou utilizavam os serviços supracitados. Além disso, investigaram-se os sentidos atribuídos ao conceito de redução de danos. Constatou-se que a utilização desses serviços possui pontos de convergência e divergência e que os momentos da busca por cada serviço não estão relacionados somente com uma demanda por tratamento. Observaram-se, também, a fragilidade na apreensão do conceito de redução de danos e a presença do ideal da abstinência na busca pelo tratamento. A partir da perspectiva dos usuários, espera-se contribuir para a ampliação das práticas de saúde mental no Sistema Único de Saúde.

ABSTRACT The debate regarding care models for problematic users of alcohol and other drugs has increased in Brazilian public policies. Based on the discussion on the abstinence and harm reduction paradigms, we sought to investigate the relationships and meanings that users attribute to such paradigms through the use of Therapeutic Communities and Psychosocial Care Centers for Alcohol and Drugs. For that, we used the semi-structured interview methodology with users of the mental health network who had already used the services mentioned above. In addition, the meanings attributed to the concept of harm reduction were investigated. It was found that the use of these services has points of convergence and divergence and that the moments of searching for each service are not related only to a demand for treatment. It was also observed a weak understanding of the concept of harm reduction and the presence of an abstinence ideal in the search for treatment. This research hopes to contribute to the expansion of mental health practices mainly, in the Brazilian Unified Health System.

Sulfur Hexafluoride 20% Versus Air 100% for Anterior Chamber Tamponade in DMEK: A Meta-Analysis.

PURPOSE: To compare intracameral 20% sulfur hexafluoride (SF6) versus 100% air as tamponade for graft attachment in Descemet membrane endothelial keratoplasty (DMEK). METHODS: Using an electronic database search on MEDLINE and CENTRAL from inception to December 2017, we performed a literature review and meta-analysis including all comparative studies of SF6 at a 20% concentration (20% SF6) versus pure air (100% air) for anterior chamber tamponade in DMEK. The primary outcome was the rebubbling rate at the final observation. The secondary outcomes were 1) the graft detachment rate, 2) mean difference (MD) in best-corrected visual acuity (BCVA), 3) manifest refraction spherical equivalent, 4) central corneal thickness (CCT), 5) percentage of endothelial cell loss (ECL), and 6) rate of pupillary block by the final observation. Statistical analysis was performed using RevMan5.3 software. RESULTS: Five retrospective studies were included, assessing 1195 eyes (SF6 277; air 918). The main indication for surgery was Fuchs endothelial dystrophy (SF6 85.2%; air 86.2%) and bullous keratopathy (SF6 10.8%; air 10.0%). Overall, studies were of moderate to good methodological quality. Patients in the SF6 group required 58% less rebubbling procedures (risk ratio 0.42, 95% confidence interval (CI), 0.31-0.56, P < 0.0001). No differences were found regarding BCVA improvement (MD 0.03, 95% CI, -0.05 to 0.11, P = 0.49). SF6 was associated with a minor hyperopic shift (MD 0.37 D, 95% CI, -0.95 to -0.21, P = 0.21). No differences were found regarding CCT, ECL, and rate of pupillary block (P > 0.05). CONCLUSIONS: In DMEK, 20% SF6 tamponade and longer postoperative time supine were associated with 58% fewer rebubbling procedures, and an ECL not statistically different from using 100% air.

Negative ßhCG and Molar Pregnancy: The Hook Effect.

Molar pregnancy, included in gestational trophoblastic disease, is a benign pathology with ability to metastasize, usually occurring with excessively high ßhCG levels. Clinical scenario is usually a woman in extremes of reproductive age presenting with amenorrhoea, pain and vaginal blood loss; signs derived from high ßhCG levels may be present (hyperthyroidism, hyperemesis). Diagnosis is based on a positive pregnancy test - usually a qualitative urinary test. The limitation of this test results from its inability to become positive in presence of markedly high levels of ßhCG, saturating the antigens used - known as the 'hook effect'. With the widespread use of gynaecological ultrasound cases of molar pregnancy have been diagnosed in timely fashion. We describe a case referred as a degenerating fibroid, with a negative urinary pregnancy test. Transvaginal ultrasound was highly suggestive of molar pregnancy, which was confirmed with a quantitative ßhCG test, allowing for timely treatment. The importance of a high index of suspicion for this pathology is tremendous to avoid the devastating consequences of a delayed diagnosis.

A gravidez molar, incluída na doença gestacional do trofoblasto, é uma patologia benigna com capacidade de metastização, cursando com níveis excessivamente elevados de ßhCG. O quadro clínico traduz-se por amenorreia, dor e perda de sangue vaginal numa mulher frequentemente no extremo da idade reprodutiva, podendo estar presentes sinais decorrentes dos níveis de ßhCG (hipertiroidismo, hiperemese). O diagnóstico é histológico, e suspeitado por um teste de gravidez positivo, sendo normalmente realizado um teste urinário qualitativo. A limitação deste advém da incapacidade de se tornar positivo na presença de níveis exageradamente altos de ßhCG, que satura os antigénios utilizados ­ 'efeito hook'. Com a ecografia ginecológica os casos de gravidez molar têm sido diagnosticados mais atempadamente. Descrevemos um caso referenciado como um mioma degenerescente, com teste de gravidez urinário negativo. A ecografia transvaginal realizada foi altamente sugestiva de gravidez molar, confirmada com um teste quantitativo de ßhCG e permitindo tratamento atempado. A importância de um elevado índice de suspeição para esta patologia é fulcral para evitar as consequências devastadoras de um diagnóstico tardio.

Biweekly vinorelbine and tegafur/uracil in patients with metastatic breast cancer previously treated with anthracyclines and taxanes: GEICAM 2000-02 phase II study.

INTRODUCTION: To assess the efficacy and safety profile of biweekly vinorelbine and tegafur/uracil (UFT) as treatment in patients with metastatic breast cancer previously treated with anthracyclines and taxanes. PATIENTS AND METHODS: Patients with histologically confirmed breast cancer, measurable disease, no more than one prior chemotherapy regimen for metastatic disease, an Eastern Cooperative Oncology Group (ECOG) performance status ≤2, and adequate bone marrow, renal and liver function were eligible. Patients received vinorelbine (30 mg/m(2) on day 1) and UFT (250 mg/m(2) daily) every two weeks for 12 cycles unless progression or unacceptable toxicity was observed. RESULTS: Thirty-seven patients were included and received 311 cycles of chemotherapy. Efficacy and toxicity analyses were carried out on an intention-to-treat basis. The overall response rate was 35% (95% CI: 20-53). With a median follow-up of 18.6 months (95% CI: 1.0-74.3), the median time to progression was 7.0 months (96% CI: 5.2-8.9) and the median overall survival was 19.4 months (95% CI: 11.1-27.8). The most common severe toxicities were neutropenia (38% of patients) and asthenia (11% of patients). CONCLUSION: The combination of biweekly vinorelbine and UFT in patients with metastatic breast cancer pretreated with anthracyclines and taxanes is a well tolerated and effective regimen. AEMPS Trial Registration No.: 00-0534.

Mucoepidermoid carcinoma of the bulbar conjunctiva - an interventional case report.

PURPOSE: Mucoepidermoid carcinoma is a rare variant of squamous cell carcinoma of the conjunctiva. It appears more frequently in the elderly, it is more aggressive than squamous cell carcinoma, and it has a higher recurrence rate and higher incidence of intraocular and orbital invasion. METHODS: We report a case of a 74-year-old man who presented to the Emergency Department with a one month history of painful red left eye. RESULTS: The patient presented with visual acuity was 10/10 in both eyes and a conjunctiva tumor on the bulbar conjunctiva of left eye. The UBM revealed a thickening of the conjunctiva-sclera complex with no signs of intraocular invasion. A biopsy was performed and the diagnosis was of mucoepidermoid carcinoma. Two local excisions with adjuvant cryotherapy and mitomycin C aplication were carried out in a period of 6 months. After 9 months of follow-up there has not been any sign of recurrence. CONCLUSIONS: The early diagnosis and treatment of carcinoma is essential not only to prevent the intraocular spread and preserve visual function but also to prevent local or systemic recurrence and dissemination.

IgA nephropathy in a patient presenting with scleritis.

Scleritis is a very uncommon manifestation in patients with IgA nephropathy. Here, we report the case of a patient presenting with diffuse anterior scleritis in which the laboratory disclosed microscopic haematuria and nephrotic range proteinuria. Renal function was normal. Serology for lupus, vasculitis and cryoglobulinaemia was negative. Rheumatoid factor was negative, and serum C3 and serum C4 were on the normal range. Serology for human immunodeficiency virus types 1 and 2, hepatitis B, hepatitis C, syphilis, and Lyme disease was also negative. A renal biopsy was performed and revealed IgA nephropathy. Oral steroids were then started, and 6 months later, the patient was asymptomatic. Scleritis did not recur, and ophthalmologic examination was normal; however, proteinuria was still in non-nephrotic range. Renal function still remains normal.
