RESUMEN

Abstract Background: Health-related quality of life assesses how diseases affect the daily life of people; there are several generic instruments for this assessment in dermatology. Skindex was created in 1996; it is a multidimensional instrument, aiming to encompass some psychological and social aspects not yet addressed by other questionnaires. Among its versions (Skindex-29, 16, and 17), Skindex-17 had not been validated in Brazil. Objectives: To validate Skindex-17 for use in Brazilians with dermatological diseases. Methods: This was a methodological, cross-sectional, and prospective study of 217 patients attended at the Dermatology Service Outpatient Clinic, Faculdade de Medicina de Botucatu - Universidade Estadual Paulista (Botucatu, SP, Brazil), from December 2017 to September 2019. The following were evaluated: content validity, filling time, internal consistency, dimensional structure, concurrent validity (DLQI), temporal stability, and responsiveness. Results: The sample consisted of 71% women, mean age (SD) of 45 (16) years; phototypes II−IV accounted for 95% of the cases. Cronbach's alpha coefficients were 0.82 and 0.93 for the symptoms and psychosocial conditions, respectively. A high correlation was observed with the DLQI score: symptoms (rho = 0.69) and psychosocial conditions (rho = 0.75). The instrument's two-dimensional structure was confirmed through confirmatory factor analysis. Temporal stability (ICC > 0.9) and score responsiveness (p ≤ 0.02) were verified. The instrument was shown to be feasible in clinical practice due to the content validation performed by professionals and patients, as well as the low time spent completing it (< 5 min). Study limitations: Single-center study, with patients exclusively from the public healthcare system. Conclusions: Skindex-17 was shown to be a valid and consistent instrument for assessing quality of life among patients with dermatological diseases, in Brazil. Its two-dimensional structure was confirmed.

RESUMEN

PURPOSE: The aim of this study is to compare the outcomes of intracavitary high-dose-rate brachytherapy (BT-IC) boost and external beam radiotherapy (EBRT) boost in patients treated with concomitant chemoradiotherapy for squamous cell carcinoma of the cervix. MATERIAL AND METHODS: It is a retrospective review of 92 patients with stage IB1-IVA cervical cancer treated with concomitant chemoradiotherapy between 2008 and 2013. All patients received pelvic 3D conformal EBRT (range, 45-50.4 Gy) concomitant with weekly cisplatin (40 mg/m2), and a BT-IC boost (37 patients: 4 fractions of 6 Gy prescribed to a point A) to the tumor or a 3D conformal EBRT boost (55 patients: 16.2 Gy), if the former was not technically feasible. RESULTS: The 5-year overall survival and recurrence-free survival rates for both groups were 68% and 55%, respectively. The 5-year overall survival and recurrence-free survival were better and statistically significant in the BT-IC group with 82% and 79%, respectively, as compared to the EBRT group with 58% and 38%, respectively. In multivariate analysis controlling for maximum tumor dimension, lymph node status, and FIGO stage, EBRT boost was associated with a statistical significant increase in the risk of recurrence (HR: 3.56; 95% CI: 1.27-10.02; p = 0.016) and a trend towards an increase in the risk of death (HR: 3.14; 95% CI: 0.97-10.17; p = 0.056). Lymph node status was also significantly associated with a greater risk of recurrence. CONCLUSIONS: BT-IC boost was associated with a lower recurrence rate and better overall survival and recurrence-free survival. EBRT boost patients had a three-fold increase in the risk of recurrence. Brachytherapy is essential in the treatment of cervical cancer and improved alternatives are needed for patients who are not candidates for standard brachytherapy applicators.

RESUMEN

Abstract Hyperzincemia and hypercalprotectinemia is a rare inflammatory disease caused by a mutation in the PSTPIP1 gene, with a dysregulation of calprotectin metabolism. Calprotectin is a zinc-binding protein with antimicrobial properties and pro-inflammatory action. The authors report the case of a 20 year-old girl with cutaneous ulcers comparable with pyoderma gangrenosum, growth failure and chronic anemia, who was given the diagnosis of hyperzincemia and hypercalprotectinemia. Measurement of serum zinc and calprotectin concentrations are indicated in these cases.

RESUMEN

Abstract: Molecular studies have shown more than one species of the genus Paracoccidioides to be the causal agent of paracoccidioidomycosis. Efforts have been made to correlate the identified species with epidemiological and clinical data of patients, aiming to determine the real meaning and impact of new species. Bearing this objective in mind, the authors report a clinical case of paracoccidioidomycosis, from São Paulo state, Brazil, that manifested as uncommon sarcoid-like cutaneous lesions and was caused by Paracoccidioides brasiliensis sensu stricto (S1a). The patient was treated with itraconazole 200mg/day for 12 months, with complete clinical remission.

RESUMEN

Amicrobial pustulosis of the folds is a chronic relapsing neutrophilic dermatosis characterized by sterile pustules compromising skin folds, scalp, face and periorificial regions. It predominantly affects women. Demodicosis is an inflammatory disease associated with cutaneous overpopulation of the mite Demodex spp., the pathogenesis of which is not completely established, but is frequently related to local immunodeficiency. A case of a young woman with amicrobial pustulosis of the folds, and isolated worsening of facial lesions, is reported; investigation revealed overlapping demodicosis. There was complete regression of lesions with acaricide and cyclin treatment. This case warns of a poorly diagnosed but disfiguring and stigmatizing disease, often associated with underlying dermatoses or inadvertent treatments on the face.

RESUMEN

Cervical cancer (CC) is one of the acquired immunodeficiency syndrome (AIDS) defining diseases and the human immunodeficiency virus (HIV) infection is thought to relate with increased acute toxicity of chemoradiotherapy (CRT).We investigated the effect of HIV status in the incidence of neutropenia associated with cisplatin-based CRT for CC and its impact in treatment completion.This is a single-center retrospective cohort study. Data collection was performed for all the consecutive stage Ib-IV CC women treated with cisplatin-based CRT from 2012 to 2016, and with known HIV status.Sixty-one patients were included, 6 were HIV+. HIV+ patients had a higher risk of neutropenia at any cycle during cisplatin CRT [adjusted odds ratio (OR) 7.3, 95% confidence interval (95% CI) 1.02-52.3; P = .05]. Despite the absolute differences, mean neutrophil count was nonsignificantly lower in HIV+ women, both at baseline [4455/µL (interquartile range, IQR: 1830-6689) vs 6340 (IQR: 1720-18,970) for HIV-, P = .98] and at the end of treatment [1752/µL (IQR: 1100-2930) vs 3147/µL (IQR: 920-18,390) in HIV-; P = .06]. Moreover, when considering the effect of time, CRT seems to induce a consistent drop of neutrophils in both groups (P = .229). No febrile neutropenia events occurred.In HIV+ women, there were more CT cycle delays (P = .013), patients were more prone to use granulocyte colony-stimulating factor (G-CSF; HIV+ 40.0% vs HIV- 4.0%; P = .04) and less likely to complete at least 5 cycles of cisplatin (P = .02). All patients received adequate dose of pelvic RT, regardless of HIV status.HIV+ patients have a significantly increased risk of neutropenia during CRT treatment for CC and are less likely to complete chemotherapy with cisplatin.

RESUMEN

Abstract: Background: Several dermatoses are mediated by histamine, such as urticaria, angioedema, and papular urticaria. There are no Brazilian studies comparing the potency of antihistamines. Objectives: To evaluate the tolerability and efficacy of the main commercial brand and generic H1 antihistamines, regarding the suppression of the wheal and flare to the histamine test. Methods: A quasi-experimental, open study with 10 healthy adults submitted to the histamine test on the ventral aspect of the forearms. After 20 minutes, wheal and flares were measured. The tests were performed after two hours of intake of dexchlorpheniramine, hydroxyzine, levocetirizine, fexofenadine, cetirizine, loratadine, ebastine, desloratadine, epinastine and rupatadine, as well as generics of loratadine, cetirizine and fexofenadine. Results: All antihistamines presented a reduction in the wheal compared to the control (p <0.02), as well as in the flare, except for rupatadine (p = 0.70). In the internal comparison, cetirizine, fexofenadine, epinastine, levocetirizine, dexchlorpheniramine and hydroxyzine were the most potent, with no difference between them (p > 0.1). As for halo, cetirizine, epinastine, hydroxyzine and fexofenadine were the most potent, with no difference between them (p > 0.1). The most common adverse effect was drowsiness, which was more prevalent among first-generation drugs (p < 0.01). Generic loratadine, fexofenadine and cetirizine halos were higher than their controls (p <0.03).. Study limitations: A single-center study evaluating only aspects related to histamine. Conclusions: Brazilian commercial antihistamines presented different profiles of inhibition of wheal and flares in the histamine test, as well as adverse effects. Generic loratadine, fexofenadine and cetirizine presented larger flares than brand drugs.

RESUMEN

Abstract Epidemiology of diseases is influenced by population socio-demographic circumstances. Therefore it can be modified along the time. There are no studies exploring epidemiological transition in dermatology. This study investigated the incidence of dermatoses in new patients from a Brazilian country town public service in 2003 and 2014. There was a significant increase in the incidence of sexually transmitted diseases, leprosy, melasma, pruritus and hidradenitis suppurativa. However, a prominent reduction in scheduling of appointments for surgeries of benign lesions, drug reactions, urticaria and superficial mycoses was detected. The identification of epidemiological trends guides the dimensioning of health system and professional qualification policies.

RESUMEN

Milker's nodule is an occupational dermatovirose caused by Parapoxvirus, which is self-limited and, due to the lack of information of health professionals, may lead to underdiagnosis. We present two cases with exuberant manifestations and classic histopathologic findings. Case 1: Male, 19 years of age, milker, presented nodules and blisters on his palm for 15 days. Case 2: Male, 33 years of age, administrative assistant, presented erythematous nodules on his palms with lymphangitis for 5 days. He had milked a cow one week before the onset of the lesions. In both cases, the histopathology was representative and coincident with the clinical hypothesis. The lesions have presented complete involution. Milker's nodule diagnosis is based on clinical presentation, epidemiology, and histopathology. The knowledge of this disease is essential for its correct diagnosis, as well as to guide the implementation of public health measures and the appropriate treatment of sick cattle.

RESUMEN

Contexto: Síndrome de Ehlers-Danlos compreende um grupo de doenças hereditárias caracterizadas pela fragilidade da pele, ligamentos, vasos sanguíneos e órgãos internos. Decorre de diferentes defeitos genéticos na via de biosíntese do colágeno, resultando em alterações na síntese e estrutura do tecido conjuntivo. Estima-se sua prevalência em 1:5.000 nascidos vivos. Descrição do caso: Mulher, de 24 anos, com aumento da mobilidade articular, da elasticidade cutânea e tendência à formação de cicatrizes atróficas após mínimos traumas desde a infância, tem avô com queixas semelhantes. Exame fundoscópico, cardiológico e ultrassonografia abdominal sem alterações. Estabeleceu-se o diagnóstico de síndrome de Ehlers-Danlos, variante clássica. Discussão: A classificação de Villefranche considera as alterações genéticas da síntese dos colágenos tipo I, III e/ou V, para subdividir a síndrome nas variantes: clássica, hipermobilidade articular, vascular, cifoescoliose, artocalásia, dermatosparaxia. A variante clássica decorre de mutações no colágeno V e é caracterizada pela tríade de hipermobilidade articular, hiperextensibilidade e cicatrizes atróficas, bem como apresentada pela paciente em questão. Conclusões: Cabe ao médico suspeitar e reconhecer a síndrome, uma vez que algumas variantes apresentam risco inclusive de morte. Esses pacientes necessitam de acompanhamento multiprofissional, com cardiologista, oftalmologista, dermatologista, reumatologista e fisioterapeuta, tendo em vista o comprometimento multissistêmico infligido pela doença.

RESUMEN

Considerable advances in cancer therapies in recent decades have reshaped the prognosis of cancer patients. There are now estimated to be over 20 million cancer survivors in the USA and Europe, numbers unimaginable a few years ago. However, this increase in survival, along with the aging of the patient population, has been accompanied by a rise in adverse cardiovascular effects, particularly when there is a previous history of heart disease. The incidence of cardiotoxicity continues to grow, which can compromise the effectiveness of cancer therapy. Cardiotoxicity associated with conventional therapies, especially anthracyclines and radiation, is well known, and usually leads to left ventricular dysfunction. However, heart failure represents only a fraction of the cardiotoxicity associated with newer therapies, which have diverse cardiovascular effects. There are few guidelines for early detection, prevention and treatment of cardiotoxicity of cancer treatments, and no well-established tools for screening these patients. Echocardiography is the method of choice for assessment of patients before, during and after cancer treatment. It therefore makes sense to adopt a multidisciplinary approach to these patients, involving cardiologists, oncologists and radiotherapists, collaborating in the development of new training modules, and performing clinical and translational research in a cardio-oncology program. Cardio-oncology is a new frontier in medicine and has emerged as a new medical subspecialty that concentrates knowledge, understanding, training and treatment of cardiovascular comorbidities, risks and complications in patients with cancer in a comprehensive approach to the patient rather than to the disease.

RESUMEN

Secondary malignancy of the penis is a rare clinical condition, often associated with disseminated genitourinary malignancies. The prognosis is poor and the treatment options include penectomy, local surgical excision, radiation therapy, chemotherapy and supportive therapy. Neither of these therapeutic options lead to superior treatment outcomes in the literature. The authors report the case of a 66 year-old man with a metastasis to the glans penis from a rectal adenocarcinoma, diagnosed two years after radical treatment for primary disease. The patient underwent palliative treatment with radiotherapy and chemotherapy, remaining asymptomatic and disease-free at one year follow-up. Close follow-up of patients with history of rectal adenocarcinoma is very important. Radiochemotherapy is a feasible and effective therapeutic option for penile metastasis, addressing both disease control and symptomatic improvement.


A doença secundária do pénis é uma situação clínica frequentemente associada a doença disseminada e as localizações mais comuns são os órgãos genito-urinários. O prognóstico é mau e as opções de tratamento incluem: penectomia; excisão local; radioterapia; quimioterapia; terapêutica de suporte. Apesar das várias terapêuticas existentes, nenhuma na literatura é apontada como superior àsrestantes. Os autores documentam o caso de um doente de 66 anos com metástase da glande peniana em contexto de adenocarcinoma do recto, diagnosticada dois anos após o tratamento da doença primária. O doente foi submetido a tratamento paliativo com radio-quimioterapia e permanece assintomático e livre de doença após um ano de seguimento. O follow-up apertado dos doentes com neoplasia do recto é mandatório. A radio-quimioterapia é uma abordagem válida, com bom controlo da doença e melhoria sintomática.

RESUMEN

PURPOSE: To report the experience and the outcomes of interstitial high-dose-rate (HDR) brachytherapy (BT) of eyelid skin cancer at the Department of Radiotherapy of Hospital de Santa Maria in Lisbon. METHODS AND MATERIALS: Seventeen patients (pts; mean age, 73.75 years) who underwent eyelid interstitial HDR BT with an (192)Ir source between January 2011 and February 2013 were analyzed. Lesions were basal (94%) and squamous (6%) cell carcinomas, on lower (88%) or upper (6%) eyelids, and on inner canthus (6%). T-stage was Tis (6%), T1 (46%), T2 (36%), and T3a (12%). The purpose of BT was radical (12%), adjuvant to surgery (71%), or salvage after surgery (18%). The BT implant and treatment planning were based on the Stepping Source Dosimetry System. The median total dose was 42.75 Gy (range, 32-50 Gy), with a median of 10 fractions (range, 9-11 fractions), twice daily, 6 h apart. The median V100 was 2.38 cm(3) (range, 0.83-5.59 cm(3)), and the median V150 was 1.05 cm(3) (range, 0.24-3.12 cm(3)). RESULTS: At a median followup of 40 months (range, 7-43 months), the local control was 94.1%. There was one local recurrence and one non-related death. The BT was well tolerated. Madarosis was the most common late effect (65% of pts) and was related with higher values of V100 (p = 0.027). Cosmetic outcomes were good and excellent in 70% of pts. CONCLUSIONS: Interstitial HDR BT is a feasible and safe technique for eyelid skin cancers, with good local control. Recurrent lesions and higher volumes receiving the prescribed dose were associated with worse outcomes.

RESUMEN

Hemorrhagic gastritis is a possible late toxicity outcome after radical radiotherapy but it is nowadays a very rare condition and most likely depends on other clinical factors. We report the case of a 77-year-old woman with a symptomatic solitary extramedullary intra-abdominal plasmacytoma and multiple gastric comorbidities, treated with external beam radiotherapy. Despite the good response to radiotherapy, the patient experienced multiple gastric bleeding a few months later, with the need of multiple treatments for its control. In this paper we will discuss in detail all aspects related to the different causes of hemorrhagic gastritis.

RESUMEN

AIM: Report the outcome of 8 patients (pts) with breast cancer (BC) treated with Tamoxifen (TAM) that developed malignant mixed Müllerian tumor (MMMT) and rare uterine sarcoma (RUS). PATIENTS AND METHODS: Retrospective study based on data collected from the department medical records between April 1999 and September 2010 among 583 pts with endometrial cancer, 36 pts with MMMT and RUS histopathology. Among them, 8 pts underwent TAM between 4 and 10 years due to a previous diagnosis of BC; all pts were post-menopausal with regular gynecological surveillance; 6 pts (75%) with abnormal uterine bleeding. The diagnosis of 6 pts (MMMT) and 2 pts (RUS) occurred at median interval of 8 years (range 4-12) after initial BC treatment. Pts underwent surgical treatment and were staged as stage I (3pts), IIIA (3pts) and IIIC (2 pts) (FIGO 1988); followed by whole pelvis irradiation (50 Gy) and intracavitary HDR brachytherapy boost (24 Gy). Two pts underwent chemotherapy (CT). Overall and disease free survival was calculated by Kaplan Meier method. RESULTS: With a median follow-up of 47 months (range 17-130), 3 pts remain alive recurrence-free of BC and RUS. Four pts died with distant metastasis within the first follow-up year, without BC. One pt died from non-related cancer cause. No evidence of local recurrence was found in the whole group of pts. At two years, DFS and OS were 40% and 80%, respectively. CONCLUSION: As reported in the literature, TAM administration and causal effect on MMMT and RUS in BC pts is still unknown. No reports about outcome from these specific pts were found.
