ABSTRACT

Introducción: El embarazo ectópico intersticial es una forma de presentación poco frecuente, con una incidencia del 2-4% de los embarazos ectópicos; sin embargo, a pesar de su baja incidencia la mortalidad es cinco veces mayor, impactando en las cifras de mortalidad materna y representando en torno al 10-15% de los casos. Objetivo: Presentar un caso de embarazo ectópico intersticial, cuya ocurrencia es poco frecuente, así como el abordaje satisfactorio del manejo médico con mifepristona y metotrexato. Caso clínico: Mujer de 28 años con antecedente de resección tubárica por quiste paraovárico derecho, quien acudió a urgencias por hallazgo en ecografía obstétrica de sospecha de embarazo intersticial izquierdo y se le administró manejo farmacológico con dosis de metotrexato y mifepristona, con éxito. Conclusiones: El manejo médico con metotrexato y mifepristona para el embarazo ectópico intersticial parece ser una elección eficaz en los casos con estabilidad hemodinámica y deseo de conservación de la fertilidad.


Background: Interstitial ectopic pregnancy represents a rare form of presentation, with an incidence of 2-4% of all ectopic pregnancies. However, despite its low incidence, it is associated with a five-fold increase in mortality, significantly impacting maternal mortality rates, accounting for approximately 10-15% of cases. Objective: To present a case of interstitial ectopic pregnancy, which is a rare occurrence, as well as the successful medical management approach with mifepristone and methotrexate. Case report: A 28-year-old women with a history of right paraovarian cyst tubal resection presented to the emergency department due to suspected left interstitial pregnancy identified on obstetric ultrasound. The patient was successfully managed with pharmacological treatment using doses of methotrexate and mifepristone. Conclusions: Medical management with methotrexate and mifepristone for interstitial ectopic pregnancy appears to be an effective choice in cases with hemodynamic stability and a desire for fertility preservation.

ABSTRACT

Inflammatory bowel disease (IBD) is a chronic condition that affects the digestive tract and can lead to inflammation and damage to the intestinal lining. IBD patients with cancer encounter difficulties since cancer treatment weakens their immune systems. A multidisciplinary strategy that strikes a balance between the requirement to manage IBD symptoms and the potential effects of treatment on cancer is necessary for effective care of IBD in cancer patients. To reduce inflammation and avoid problems, IBD in cancer patients is often managed by closely monitoring IBD symptoms in conjunction with the necessary medication and surgical intervention. Anti-inflammatory medications, immunomodulators, and biologic therapies may be used for medical care, and surgical options may include resection of the diseased intestine or removal of the entire colon. The current study provides a paradigm for shared decision-making involving the patient, gastroenterologist, and oncologist while considering recent findings on the safety of IBD medicines, cancer, and recurrent cancer risk in individuals with IBD. We hope to summarize the pertinent research in this review and offer useful advice. (AU)

ABSTRACT

El metotrexato es un fármaco análogo del ácido fólico ampliamente utilizado en el tratamiento de enfermedades autoinmunes, leucemias y linfomas. Su uso puede ocasionar la aparición de múltiples efectos adversos entre los que se encuentran aquellos relacionados con la presencia de toxicidad neurológica, que puede presentarse de forma aguda, subaguda o crónica. La neurotoxicidad subaguda es aquella que ocurre típicamente entre los 2 y los 14 días posteriores a la administración y puede manifestarse con una amplia gama de síntomas neurológicos. En la mayoría de los casos, no recurre con futuras exposiciones al medicamento. Presentamos tres casos de neurotoxicidad subaguda por metotrexato con manifestaciones clínicas diferentes en pacientes oncohematológicos que se internaron entre los años 2018 y 2020. Dos de ellos presentaron recurrencia frente a la nueva administración del fármaco y todos evidenciaron lesiones en resonancia magnética nuclear.


Methotrexate is a folic acid analogue widely used in the treatment of autoimmune diseases, leukemias, and lymphomas. Methotrexate use may cause multiple adverse effects, including those related to the presence of neurological toxicity, which may be acute, subacute, or chronic. Subacute neurotoxicity typically occurs between 2 and 14 days after administration and may present as a wide range of neurological symptoms. In most cases, it does not recur with future exposures to the drug. Here we describe 3 cases of subacute methotrexate neurotoxicity with different clinical manifestations in patients with oncohematological disease who were hospitalized between 2018 and 2020. Two of them showed recurrence with a new drug administration. Lesions were observed in the magnetic resonance imaging tests of all of them.

ABSTRACT

Objetivo: Avaliar o índice de sucesso do tratamento da gravidez ectópica com o protocolo de dose única do metotrexato e verificar sua correlação com variáveis clínicas e dados dos exames complementares. Métodos: É um estudo epidemiológico observacional, analítico, retrospectivo, de delineamento transversal. Foi realizado de janeiro de 2014 a agosto de 2020 em um hospital público, de ensino, em nível terciário, do Sul do Brasil. Em 73 casos com diagnóstico de gestação ectópica íntegra, foi utilizado o protocolo de dose única de metotrexato intramuscular, com a dose de 50 mg/m2 de superfície corporal. As variáveis do estudo foram relacionadas ao sucesso do tratamento e abordaram as características clínicas na admissão, dos exames complementares e do tratamento realizado. As variáveis foram comparadas por análise de regressão de Poisson. O nível de significância estabelecido foi de p < 0,05. Resultados: O índice de sucesso foi de 83,6%, e em nove casos foi necessária uma segunda dose da medicação. Nível de ß-hCG inicial superior a 5.000 mUI/mL foi relacionado a menor chance de sucesso (odds ratio ajustado de 0,20 [0,05-0,95]). Tamanho da imagem anexial, presença de líquido livre na cavidade abdominal e demais variáveis estudadas não afetaram a chance de sucesso do tratamento. Conclusão: O protocolo de dose única de metotrexato mostrou-se uma opção válida para o tratamento da gestação ectópica íntegra, notadamente quando o nível de ß-hCG inicial é inferior 5.000 mUI/mL.


Objective: The purpose of the present study is to evaluate the success rate of treatment of ectopic pregnancy with the single-dose methotrexate protocol and to verify its correlation with clinical variables and complementary exam data. Methods: This is a retrospective epidemiological observational analytical cross-sectional study. It was carried out from January 2014 to August 2020 in a tertiary level teaching hospital in southern Brazil. In 73 cases with a diagnosis of intact ectopic pregnancy, the intramuscular methotrexate single-dose protocol was applied with a dose of 50 mg/m2 of body surface. The study variables were related to the success of the treatment and addressed the clinical characteristics on admission, the complementary exams and the treatment performed. The variables were compared by Poisson regression analysis. The level of significance was set at p < 0.05. Results: The success rate was 83.6%, and in nine cases a second dose of the medication was necessary. An initial ß-hCG level greater than 5,000 mIU/mL was related to a lower chance of success (adjusted odds ratio of 0.20 [0.05- 0.95]). The size of the adnexal image, the presence of free fluid in the abdominal cavity and other variables studied did not affect the chance of a successful treatment. Conclusion: The methotrexate single-dose protocol proved to be a valid option for the treatment of intact ectopic pregnancy, notably when the initial ß-hCG level is below 5,000 mIU/mL.

ABSTRACT

SUMMARY: We aimed to investigate the protective effect of linoleic acid on liver toxicity induced by methotrexate. The study was carried out in partnership with the Department of Anatomy and Department of Medical Pharmacology of Çukurova University Faculty of Medicine, using the laboratory facilities of the Department of Medical Pharmacology. Human hepatocyte cell line (CRL- 11233) cells obtained from the American Type Culture Collection Organization (ATCC) were used. Expressions of apoptotic pathway markers, apoptosis inducing factor (AIF), BAX, BCL 2, GADD 153, 78-kDa glucose-regulated protein (GRP78), and CASPASE-3 were evaluated. All analyzes were examined in four groups (Group 1; control, Group 2; linoleic acid given, Group 3; methotrexate given and Group 4; linoleic acid and methotrexate given). The mean ± standard error values of the obtained results as nanogram / milliliter (ng / ml) are in Group I, Group II, Group III and Group IV, respectively; AIF values, 0.4150 ± 0.1208, 0.3633 ± 0.2389, 1.792 ± 0.3611 and 1.077 ± 0.1646, BAX values, 0.900 ± 0.1864, 1.002 ± 0.2098, 8.352 ± 1.467 and 4.295 ± 1.522, BCL 2 values, 13.93 ± 1.198, 13.92 ± 1.739, 2.938 ± 1.059 and 9.250 ± 1.492, GADD 153, 0.7333 ± 0.1751, 0.7067 ± 0.2115, 1.650 ± 0.2950 and 1.237 ± 0.1805, GRP78, 0.4767 ± 0.1804, 0.5233 ± 0.1590, 2.183 ± 0.2639 and 1.112 ± 0.2693, CASPASE-3 values , 1.127 ± 0.2033, 0.8317 ± 0.3392, 13.50 ± 1.871 and 8.183 ± 1.030.

ABSTRACT

Abstract Methotrexate on its oral and intravenous administration results in unwanted adverse effects. This drawback can be overcome by transdermal delivery because of its painless objective for systemic drug administration. Transfersomes are ultra-deformable vesicles with the flexibility to reach deeper tissues of the skin. The objective of this research work was to develop methotrexate transfersomal gel by thin film hydration technique, evaluated for entrapment efficiency, deformability, mean vesicle size, and stability, and incorporated into carbopol gel for ease of handling and skin applicability for a longer period of retention on skin. MTX-TFS gel & conventional gel were characterized for consistency, transparency, viscosity, and pH. Ex-vivo skin permeation studies were performed using abdominal goat skin and drug release kinetic parameters and transdermal flux were calculated using mathematical models. The results indicate that MTX was successfully entrapped (84.77 ± 2.35 %w/w) in transfersomes having 240±1.6 nm vesicle sizes and 27.13±0.7 deformability index. The gel was permeated through the skin at a rate of 28.12±2.58 µg/cm2/hr as compared to the conventional gel (10.35±2.14 µg/cm2/ hr). From the study, it was concluded that the MTX-TFS gel can be used as a possible substitute for the conventional formulation for transdermal drug delivery due to 3 times improvement in transdermal flux.

ABSTRACT

@#Hypertrophic lichen planus (HLP) is a papulosquamous eruption presenting with extremely pruritic hyperkeratotic flat-topped papules, plaques, and nodules. This is a case of 38-year-old male who presented with a 2-month history of generalized erythematous-to-hyperpigmented papules, patches, and plaques topped with white-to-gray oyster shell-like scales on a background of hyperpigmented macules and patches. There was no involvement of the conjunctival, otic, oral, and genital mucosae, and palmar and plantar aspects of the hands and feet. Dermoscopy showed reticular pearly white structures corresponding to the Wickham striae, comedo-like openings, blue-gray dots, brownish-black dots, and scales. Histopathologic examination revealed marked compact hyperkeratosis, wedge-shaped hypergranulosis, irregular saw-toothed epidermal acanthosis, scattered dyskeratotic keratinocytes, and superficial perivascular lichenoid infiltrate of lymphocytes, histiocytes, and melanophages. The patient was managed as a case of HLP. He was started on methotrexate 10 mg per week, bath psoralen photochemotherapy (PUVA) three times a week, betamethasone valerate 1mg/g cream twice a day for 2 weeks alternating with tacrolimus 0.1% ointment twice a day for another 2 weeks, 10% lactic acid, emollients, and sunscreen. After 6 months of treatment, there was almost 80% improvement of lesions and relief of pruritus.

ABSTRACT

@#Psoriasis is a systematic immune-mediated inflammatory disease where there is an increased cell turnover of the skin leading to scaling, drying, and erythema. The occurrence of pemphigus foliaceus, an autoimmune blistering disease (AIBD) characterized by flaccid bullae and erosions, is rare when concomitantly present with psoriasis. Treatment options for these diseases may overlap. We report a case of a 44-year-old female who presented with both psoriasis and pemphigus foliaceus successfully treated with methotrexate.

ABSTRACT

OBJECTIVE@#To investigate the diagnostic efficacy of seven glomerular filtration rate (GFR) evaluation formulas Schwartz2009, Schwartz1976, Counahan-Barratt, Filler, CKD-EPIscysc, Cockrofi-Gault, CKD-EPIScysC-Scr in high concentration of methotrexate (HDMTX) chemotherapy dose adjusted cut-off point (GFR ≤85 ml/min) in children with acute lymphoblastic leukemia (ALL).@*METHODS@#One hundred and twenty-four children with ALL were included in the study. GFR determined by renal dynamic imaging (sGFR) was used as the standard to evaluate the accuracy, consistency of eGFR calculated by seven formulas and sGFR, and the diagnostic efficacy of each formula when the sGFR ≤85 ml/min boundary.@*RESULTS@#All of the accuracy of eGFR estimated by Schwartz2009 were greater than 70% in the 0-3, >4 and ≤6, >6 and ≤9, >9 and ≤16 years old group and male group, and the consistency exceeded the professional threshold. When the sensitivity of the ROC curve sGFR ≤85 ml/min was 100% of CKD-EPIscysc in the 0-3, >3 and ≤4 years old group, Filler in the >3 and ≤4 years old group, and Cockrofi-Gault in the >6 and ≤9 years old group, the specificity was 73.02%, 78.95%, 78.95%, 69.32%, respectively, and the AUC under the ROC curve was the largest (P<0.05).@*CONCLUSION@#Schwartz2009 formula predicts the highest accuracy of eGFR in the 7 glomerular filtration rate. CKD-EPIscysc, Filler, and Cockrofi-Gault formulas have more guiding signi-ficance for the adjustment of HDMTX chemotherapy in pre-adolescence in children with ALL when sGFR ≤85 ml/min.

ABSTRACT

The lungs are one of the most common extra-articular organs involved in rheumatoid arthritis (RA), which is reported to occur in up to 60% to 80% of RA patients. Respiratory complications are the second leading cause of death due to RA. Although there is a wide spectrum of RA-associated respiratory diseases, interstitial lung disease is the most common manifestation and it impacts the prognosis of RA. There has been progress in understanding the management and progression of rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and RA-associated respiratory diseases recently, for example, opportunistic pulmonary infectious diseases and toxicity from RA therapies. From a chest physicians' perspective, we will update the diagnosis and treatment of RA-associated ILD, methotrexate-associated lung disease, and the complication of Pneumocystis jiroveci pneumonia in RA in this review.

ABSTRACT

OBJECTIVE@#To analyze recurrence and progression patterns of primary central nervous system lymphoma (PCNSL) in patients without whole brain radiotherapy (WBRT) and assess the value of WBRT in PCNSL treatment.@*METHODS@#This retrospective single-center study included 27 patients with PCNSL, who experienced recurrence/progression after achieving complete remission (CR), partial remission, or stable disease following initial treatments with chemotherapy but without WBRT. The patients were followed up regularly after the treatment for treatment efficacy assessment. By comparing the anatomical location of the lesions on magnetic resonance images (MRI) at the initial diagnosis and at recurrence/progression, we analyzed the patterns of relapse/progression in patients with different treatment responses and different initial status of the lesions.@*RESULTS@#MRI data showed that in 16 (59.26%) of the 27 patients, recurrence/progression occurred in out-field area (outside the simulated clinical target volume [CTV]) but within the simulated WBRT target area in 16 (59.26%) patients, and within the CTV (in-field) in 11 (40.74%) patients. None of the patients had extracranial recurrence of the tumor. Of the 11 patients who achieved CR after the initial treatments, 9 (81.82%) had PCNSL recurrences in the out-field area but within WBRT target area; of the 13 patients with a single lesion at the initial treatment, 11 (84.62%) experienced PCNSL recurrence in the out-field area but within WBRT target area.@*CONCLUSIONS@#Systemic therapy combined with WBRT still remains the standard treatment for PCNSL patients, especially those who achieve CR after treatment or have a single initial lesion. Future prospective studies with larger sample sizes are needed to further explore the role of low-dose WBRT in PCNSL treatment.

ABSTRACT

OBJECTIVE@#To investigate the correlation between single-nucleotide polymorphism (SNP) of ARID5B gene and resistance to methotrexate (MTX) in children with acute lymphoblastic leukemia (ALL).@*METHODS@#A total of 144 children with ALL who were treated in General Hospital of Ningxia Medical University from January 2015 to November 2021 were enrolled and divided into MTX resistant group and non-MTX resistant group, with 72 cases in each group. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) technology was used to measure the SNP of ARID5B gene in all children and analyze its correlation with MTX resistant.@*RESULTS@#There were no significant differences in the genotype and gene frequency of rs7923074, rs10821936, rs6479778, and rs2893881 between MTX resistant group and non-MTX resistant group (P>0.05). The frequency of C/C genotype in the MTX resistant group was significantly higher than that in the non-MTX resistant group, while the frequency of T/T genotype was opposite (P<0.05). The frequency of C allele in the MTX resistant group was significantly higher than that in the non-MTX resistant group, while the frequency of T allele was opposite (P<0.05). Multivariate logistic regression analysis showed that ARID5B gene rs4948488 TT genotype and T allele frequency were risk factors for MTX resistant in ALL children (P<0.05).@*CONCLUSION@#The SNP of ARID5B gene is associated with MTX resistant in ALL children.

ABSTRACT

RESUMO A coriorretinopatia de Birdshot é uma uveíte posterior bilateral crônica rara que acomete, preferencialmente, mulheres de meia-idade. O quadro clínico é composto de pouco ou nenhum processo inflamatório de segmento anterior, associado a vitreíte e lesões coriorretinianas ovoides branco-amareladas de característica hiperfluorescente na angiofluoresceinografia e hipofluorescente na angiografia com indocianina verde. O tratamento se dá por meio de corticoides e outras drogas imunossupressoras. Todavia, em alguns casos, a doença é refratária a tal terapêutica, sendo necessário lançar mão de outras drogas, como os agentes biológicos. O presente artigo busca relatar um caso de coriorretinopatia de Birdshot em ajuste de terapia imunossupressora que evoluiu com má resposta às drogas iniciais e bom controle após uso de imunobiológico e discutir as opções terapêuticas disponíveis atualmente.


ABSTRACT Birdshot chorioretinopathy is a rare chronic bilateral posterior uveitis that preferentially affects middle-aged women. The clinical picture is composed of little or no anterior segment inflammatory process, associated with vitritis and yellowish-white ovoid chorioretinal lesions with hyperfluorescent characteristics on fluorescein angiography and hypofluorescent characteristics on green indocyanine green angiography. Treatment is with corticosteroids and other immunosuppressive drugs. However, in some cases, the disease is refractory to such therapy, making it necessary to resort to other drugs such as biological agents. The present article seeks to report a case of Birdshot chorioretinopathy in an adjustment of immunosuppressive therapy that evolved with poor response to the initial drugs and good control after the use of immunobiologicals and discuss the currently available therapeutic options.

Abstract Objective The availability of reliable and inexpensive markers that can be used to determine the risk of rupture during methotrexate (MTX) treatment in ectopic pregnancies (EPs) is considerable. The aim of the present study is to investigate the role of systemic inflammatory markers such as leukocytes (or white blood cells, WBCs), the neutrophil-to-lymphocyte ratio (NLR), and platelet distribution width (PDW), which are among the parameters of the complete blood count (CBC), in the prediction of rupture of EPs under MTX treatment. Materials and Methods A total of 161 patients with tubal EP who underwent a single-dose methotrexate (MTX) protocol were retrospectively analyzed, and the control group (n = 83) included patients cured by MTX, while the ruptured group (n = 78) included patients who were operated on for tubal rupture during the MTX treatment. The features of EP, beta-human chorionic gonadotropin (β-hCG) levels, sonographic findings, and CBC-derived markers such as WBC, NLR, and PDW, were investigated by comparing both groups. Results The NLR was found to be higher in the ruptured group, of 2.92 ± 0.86%, and significantly lower in the control group, of 2.09 ± 0.6%. Similarly, the PDW was higher (51 ± 9%) in the ruptured group, and it was significantly lower a (47 ± 13%) in the control group (p < 0.05). Other CBC parameters were similar in both groups (p > 0.05). Conclusion Systemic inflammation markers derived from CBC can be easily applied to predict the risk of tubal rupture in Eps, since the CBC is an inexpensive and easy-to-apply test, which is first requested from each patient during hospitalization.


Resumo Objetivo A disponibilidade de marcadores confiáveis e baratos que podem ser usados para determinar o risco de ruptura durante o tratamento com metotrexato (MTX) em gestações ectópicas (GEs) é considerável. O objetivo do presente estudo é investigar o papel de marcadores inflamatórios sistêmicos, como leucócitos (ou glóbulos brancos, glóbulos brancos), a relação neutrófilo-linfócito (NLR) e largura de distribuição de plaquetas (PDW), que estão entre os parâmetros do hemograma completo (hemograma), na predição de ruptura de PEs sob tratamento com MTX. Materiais e Métodos Foram analisados retrospectivamente 161 pacientes com EP tubária submetidas a protocolo de dose única de metotrexato (MTX), sendo que o grupo controle (n = 83) incluiu pacientes curadas com MTX, enquanto o grupo roto (n = 78) incluíram pacientes operadas por ruptura tubária durante o tratamento com MTX. As características de EP, beta-gonadotrofina coriônica humana (β-hCG), achados ultrassonográficos e marcadores derivados de CBC, como WBC, NLR e PDW, foram investigados comparando os dois grupos. Resultados A RNL foi maior no grupo roto, de 2,92 ± 0,86%, e significativamente menor no grupo controle, de 2,09 ± 0,6%. Da mesma forma, o PDW foi maior (51 ± 9%) no grupo roto, e foi significativamente menor a (47 ± 13%) no grupo controle (p < 0,05). Outros parâmetros do hemograma foram semelhantes em ambos os grupos (p > 0,05). Conclusão Marcadores inflamatórios sistêmicos derivados do hemograma podem ser facilmente aplicados para predizer o risco de ruptura tubária na Eps, uma vez que o hemograma é um exame de baixo custo e fácil aplicação, solicitado primeiramente a cada paciente durante a internação.

ABSTRACT

Abstract Objective Cervical pregnancy is challenging for the medical community, as it is potentially fatal. The treatment can be medical or surgical; however, there are no protocols that establish the best option for each case. The objective of the present study was to describe the cases of cervical pregnancy admitted to a tertiary university hospital over a period of 18 years. Methods A retrospective study based on a review of the medical records of all cervical pregnancies admitted to the Women's Hospital at Universidade Estadual de Campinas, Southeastern Brazil, from 2000 to 2018. Results We identified 13 cases of cervical pregnancy out of a total of 673 ectopic pregnancies; only 1 case was initially treated with surgery because of hemodynamic instability. Of the 12 cases treated conservatively, 7 were treated with single-dose intramuscular methotrexate, 1, with intravenous and intramuscular methotrexate, 1, with intravenous methotrexate, 1, with 2 doses of intramuscular methotrexate, and 2, with intra-amniotic methotrexate. Of these cases, one had a therapeutic failure that required a hysterectomy. Two women received blood transfusions. Four women required cervical tamponade with a Foley catheter balloon for hemostasis. There was no fatal outcome. Conclusion Cervical pregnancy is a rare and challenging condition from diagnosis to treatment. Conservative treatment was the primary method of therapy used, with satisfactory results. In cases of increased bleeding, cervical curettage was the initial treatment, and it was associated with the use of a cervical balloon for hemostasis.


Resumo Objetivo A gravidez ectópica cervical é um desafio para a comunidade médica, pois pode ser fatal. O tratamento pode ser clínico ou cirúrgico, mas não existem protocolos que estabeleçam a melhor opção para cada caso. O objetivo deste estudo foi descrever os casos de gravidez ectópica cervical internados em um hospital universitário terciário durante 18 anos. Métodos Estudo retrospectivo com revisão de prontuários de todas as gestações ectópicas cervicais internadas no Hospital da Mulher da Universidade Estadual de Campinas de 2000 a 2018. Resultados Foram identificados treze casos de gestação ectópica cervical em um total de 673 gestações ectópicas; apenas 1 caso foi inicialmente tratado com cirurgia por causa de instabilidade hemodinâmica. Dos 12 casos tratados conservadoramente, 7 foram tratados com metotrexato por via intramuscular em dose única, 1, com metotrexato pelas vias intravenosa e intramuscular, 1, com metotrexato por via intravenosa, 1, com 2 doses de metotrexato por via intramuscular, e 2, com metotrexato por via intra-amniótica. Desses casos, um apresentou falha terapêutica, e realizou-se uma histerectomia. Duas mulheres receberam transfusões de sangue. Quatro mulheres necessitaram de tamponamento cervical com cateter balão de Foley para hemostasia. Não houve casos fatais. Conclusão A gravidez cervical é uma condição rara e desafiadora desde o diagnóstico até o tratamento. O tratamento conservador foi o principal método terapêutico utilizado, com resultados satisfatórios. Nos casos de sangramento aumentado, a curetagem cervical foi o tratamento inicial, e foi associada ao uso de balão cervical para hemostasia.

ABSTRACT

BACKGROUND: Giant cell Arteritis (GCA) is the most common systemic vasculitis in patients over 50 years. Diagnosis is based on clinical, laboratory, imaging and biopsy. Temporal artery biopsy (TAB) may be inconclusive in up to 40% of patients. AIM: To describe disease features of patients diagnosed with GCA. MATERIAL AND METHODS: Review of pathology reports of giant cell arteritis and clinical records of patients seen with the diagnosis between 2000 and 2019. Demographic, clinical, laboratory, histopathology, imaging, treatment and follow-up variables were analyzed. RESULTS: We fetched 32 patients with a median age at diagnosis of 70.5 years (range 57-90), 81% women. Twenty eight percent had polymyalgia. 72% had only cranial symptoms, 12% had extracranial involvement and 13% exclusive extracranial involvement. The median time from onset of symptoms to diagnosis was two months (range 0.5-8). All had elevated erythrocyte sedimentation rate and c reactive protein. A TAB was performed in 27 patients and in 17 (65.4%) it confirmed the diagnosis. Transmural inflam- mation was the most frequent finding. All patients received steroids. Follow-up information was available from 25 patients and 92% received a steroid-spa- ring agent, usually methotrexate (74%). Ninety two percent achieved clinical remission in the first year and 59% had minor relapses during steroid tapering. CONCLUSIONS: Our patients showed frequent extracranial involvement and TAB was a useful diagnostic tool.

ABSTRACT

La morfea lineal en golpe de sable es una entidad dermatológica caracterizada por la inflamación esclerosante y progresiva del tejido cutáneo en la región frontal y/o en el cuero cabelludo. La cefalea y las crisis convulsivas son dos de los síntomas extracutáneos más frecuentes y están causados por el crecimiento subyacente de la lesión. Es importante un diagnóstico temprano para frenar la progresión e intentar evitar las complicaciones secundarias, principalmente neurológicas. El diagnóstico se basa en el cuadro clínico y el estudio histológico, que permite la confirmación definitiva. El tratamiento de elección es la terapia combinada con corticoides orales y metotrexato. Aun con el tratamiento farmacológico adecuado, esta patología puede presentar un curso recidivante y dejar secuelas a largo plazo. Se presenta el caso de una niña en quien se realizó un diagnóstico rápido de esta enfermedad, a pesar de un cuadro clínico inespecífico. Fue tratada con metotrexato oral con buena respuesta, sin efectos secundarios.


Linear morphea in coup de sabre is a dermatological entity characterized by progressive, sclerosing inflammation of the skin tissue in the frontal region and on the scalp. Headache and seizures are two of the most frequent extracutaneous symptoms and they are caused by the growth of the lesion towards underlying structures. An early diagnosis is important to stop cranial progression and try to avoid secondary complications, mainly neurological. The diagnosis is relied on compatible clinical signs and a pathological study that allows a definitive confirmation. The treatment of choice is combination therapy with oral corticosteroids and methotrexate. Despite an adequate pharmacological treatment, this pathology can present a recurrent course and cause long-term sequelae. We present the case of a girl who was diagnosed quickly, despite a not very noticeable symptoms. She has been treated with oral methotrexate with a good response, without side effect

ABSTRACT

We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia (GTN). In this trial (NCT01823315), 276 patients were analyzed. Patients were allocated to three initiated regimens: single-course methotrexate (MTX), single-course MTX + dactinomycin (ACTD), and multi-course MTX (control arm). The primary endpoint was the complete remission (CR) rate by initial drug(s). The primary CR rate was 64.4% with multi-course MTX in the control arm. For the single-course MTX arm, the CR rate was 35.8% by one course; it increased to 59.3% after subsequent multi-course MTX, with non-inferiority to the control (difference -5.1%,95% confidence interval (CI) -19.4% to 9.2%, P = 0.014). After further treatment with multi-course ACTD, the CR rate (93.3%) was similar to that of the control (95.2%, P = 0.577). For the single-course MTX + ACTD arm, the CR rate was 46.7% by one course, which increased to 89.1% after subsequent multi-course, with non-inferiority (difference 24.7%, 95% CI 12.8%-36.6%, P < 0.001) to the control. It was similar to the CR rate by MTX and further ACTD in the control arm (89.1% vs. 95.2%, P =0.135). Four patients experienced recurrence, with no death, during the 2-year follow-up. We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN.
