RESUMO
OBJECTIVE: To assess the changes in body composition of burn patients through electrical bioimpedance in the phases of response to trauma. METHODS: a longitudinal observational study, carried out from October 2019 to March 2020. Sociodemographic, clinical, epidemiological, anthropometric and body composition data were collected. Statistical analysis was performed with SPSS, considering a significance of 5%. The comparison between variables was performed using the paired Student's t test. RESULTS: the sample consisted of 58 adult burn patients, with a mean age of 38.2±12.5 years. The mean body surface area (BSA) with burns was 10.8±7.3%. Nutritional assessment demonstrated a depletion of body weight, Body Mass Index, fat-free mass and muscle mass in the phases of response to trauma (p<0.005). CONCLUSION: metabolic alterations in the different phases of the metabolic response to trauma led to a depletion of the nutritional status of burn patients of both sexes during hospitalization.

RESUMO
Introduction: Symptomatic heart disease may be present in patients with advanced-stage acromegaly. However, earlier assessment of subclinical ventricular systolic dysfunction can be accomplished through speckle-tracking echocardiography (STE) for the study of myocardial strain. The few such studies in this population to date have produced conflicting results. This study was performed to evaluate the parameters of ventricular strain in patients with acromegaly with no cardiac symptoms. Methods: In this prospective observational study, STE was performed in patients with active acromegaly with no detectable heart disease and in a control group to assess ventricular dysfunction through global longitudinal strain (GLS), radial strain, circumferential strain, and twist. The left ventricular (LV) ejection fraction, LV mass index, and relative wall thickness were also compared between the groups. Results: Twenty-five patients with active acromegaly (median age, 49 years; median disease duration, 11 years) and 44 controls were included. LV hypertrophy was more prevalent in the acromegaly group (40% vs. 19%, p < 0.01). The LV ejection fraction was similar between the groups (65.2% ± 5.99% vs. 62.9% ± 7.41%). The mean GLS (-18.8 ± 2.49 vs. -19.7 ± 3.29, p = 0.24), circumferential strain (-16.7 ± 3.18 vs. -16.6 ± 3.42, p = 0.90), and twist (14.6 ± 5.02 vs. 15.1 ± 3.94, p = 0.60) were not significantly different between the groups. Conclusion: Despite showing higher rates of LV hypertrophy, patients with long-term acromegaly had no impairment of ventricular contractility as assessed by strain echocardiography when compared with a control group.

ABSTRACT The assessment of the nutritional status of hospitalized patients is fundamental to the establishment of the diagnosis. For bedridden patients, however, it is not possible to determine simple measures, such as weight and height, which are the most widely used variables for nutritional assessments. Objective: Compare real and estimated anthropometric measures in hospitalized patients. Methods: A cross-sectional study was conducted with adult (>18 years of age) and senior patients (>60 years of age) admitted for clinical or surgical treatment in the general surgery infirmary of Governador Paulo Guerra Restauração Hospital. Data (sex, age, clinical diagnosis, real weight, real height, body mass index, knee height and arm circumference) were collected using nutritional follow-up charts and tabulated using Excel 2016. Statistical analyses were performed in SPSS® version 21.0. Results: One hundred and twenty patients participated in the study (median age: 55 years). Most were adults (73.3%) and women (53.3%). The mean differences in weight between the estimated and real measures were statistically significant (p=0.000), with an overestimation of this variable. Regarding height, the estimated values differed significantly from the real values in both men and women (p<0.000) and the difference was larger among the seniors (mean: -0.072). No significant difference was found between the real and estimated body mass index (p= 0.44). Conclusion: In the comparison of methods for estimating weight and height to real measures, a tendency was found to overestimate these body measures.
RESUMEN La evaluación del estado nutricional de los pacientes hospitalizados es esencial para establecer su diagnóstico. Sin embargo, para los pacientes postrados en cama, no se pueden realizar medidas sencillas como el peso y la altura, que son las más utilizadas para el diagnóstico nutricional. Objetivo: Comparar mediciones antropométricas reales y estimadas en pacientes hospitalizados. Metodología: Estudio transversal, que incluye pacientes adultos (>18 años) y personas mayores de 60 años, ingresados para tratamiento clínico o quirúrgico en la sala de cirugía general del Hospital da Restauração Governador Paulo Guerra. Los datos (sexo, edad, diagnóstico clínico, peso real, altura real, índice de masa corporal, altura de la rodilla y circunferencia del brazo) se recopilaron mediante los formularios de monitoreo nutricional y se tabularon en el software Excel 2016. Los análisis estadísticos se realizaron con SPSS®, versión 21.0. Resultados: 120 pacientes con mediana de 55 años, en su mayoría adultos (73,3%) y mujeres (53,3%). Las diferencias promedio entre las mediciones estimadas y reales fueron estadísticamente significativas, con sobreestimación del peso (p<0,0001). Con respecto a la altura, fue posible identificar que las medidas estimadas diferían significativamente (p<0,0001) de las reales para hombres y mujeres, y que esta variación era aún mayor entre los ancianos (media: -0,072). No hubo diferencias estadísticamente significativas entre el índice de masa corporal real y el estimado (p= 0,44). Conclusión: Al comparar las metodologías para estimar el peso y la altura con las mediciones reales, fue posible observar una tendencia de los métodos a sobreestimar estas mediciones corporales.
RESUMO
OBJETIVO: Descrever a evolução clínica e nutricional de paciente queimado fasciotomizado com uso de terapia nutricional imunomoduladora. RELATO DO CASO: Estudo do tipo relato de caso, realizado durante 52 dias na Unidade de Tratamento de Queimados do Hospital da Restauração Governador Paulo Guerra, em Recife-PE. Paciente do sexo masculino, adulto, 27 anos, proveniente do interior de Pernambuco, sem comorbidades, queimado por eletricidade de alta voltagem após acidente de trabalho, evoluindo com síndrome compartimental do membro superior esquerdo e submetido a fasciotomia. Prescrita dieta por via oral associada à suplementação imunomoduladora de característica hipercalórica, hiperproteica, contendo arginina e alto teor de oligoelementos e micronutrientes. Durante o internamento, o paciente apresentou manutenção do estado nutricional, com adesão de novos hábitos alimentares que contribuíram para a cicatrização do membro afetado. CONCLUSÃO: A terapia nutricional imunomoduladora individualizada beneficiou a reparação tecidual, cicatrização e redução do risco de amputação em paciente queimado fasciotomizado.
OBJECTIVE: To describe the clinical and nutritional evolution of a burn patient submitted to fasciotomy and immunomodulating nutritional therapy. CASE REPORT: A case-report study was conducted over a 52-day period at the Burn Treatment Unit of Governador Paulo Guerra Restauração Hospital in the city of Recife, Brazil. A 27-year-old male patient, brown skin color, from the instate region of the state of Pernambuco, without comorbidities, suffered a high-voltage electrical burn after a work accident, developing compartment syndrome of the left upper limb, and was submitted to fasciotomy. An orally diet was prescribed associated with immunomodulatory supplementation with a hypercaloric, hyper protein character, with arginine and high content of trace elements and micronutrients. During hospitalization, the patient's nutritional status was maintained with the adherence to new dietary habits, which contributed to the healing of the affected limb. CONCLUSIONS: Individualized immunomodulating nutritional therapy benefits the tissue repair and healing processes, reducing the risk of amputation in burn patients submitted to fasciotomy.

The objective of this study was to assess the influence of weight gain on the lipid profile of 135 adolescents between 10 - 14 years at baseline and 15 - 19 years at follow-up, enrolled in public schools in Recife, Brazil. The results showed that a BMI z-score correlated with triglycerides (TG) and with high density trigliceride lipopoteine ratio (TG/HDL-c) in males. In females, high z-score correlated with total cholesterol (TC) and low density lipoprotein (LDL-c). In males, for each unit increase in z-score, TG increased by 14.7 mg/dL and the TG/HDL-c ratio increased by 0.4. Among females, TC increased by 9.4 mg/dL, LDL-c increased by 11.6 mg/dL, non-HDL cholesterol increased by 11.8 mg/dL, and HDL-c decreased by 2.3 mg/dL. In males, excessive weight gain was associated with an increase in TG and TG/HDL-c; in females, it was associated with a higher increase in TG/HDL-c and non-HDL cholesterol. However, z-score variation can be a good predictor of lipid profile changes, even in those that are within the normal range.
El objetivo de este estudio fue evaluar la influencia del aumento de peso en el perfil lipídico de 135 adolescentes de edades entre 10 y 14 años de edad al inicio del estudio y de 15 a 19 años en el seguimiento. Los adolescentes pertenecían a escuelas públicas de Recife, Brasil. Los resultados mostraron que el alto puntaje z de indice de masa corporase (IMC) correlacionaba con triglicéridos (TG) y con relación de triglicéridos con lipoproteínas de alta densidad (TG/HDL-c) en los hombres. En las mujeres, puntaje z de IMC se correlacionó con CT y lipoproteína de baja densidad (LDL-c). En los hombres, por cada unidad de aumento en el puntaje z, los TG aumentaron en 14,7 mg/dL y la relación TG / HDL-c aumentó en 0,4; en las mujeres, el CT aumentó en 9,4 mg/dL, el LDL-c aumentó en 11,6 mg/dL, el colesterol no HDL aumentó en 11,8 mg / dL y el HDL-c disminuyó en 2,3 mg/dL. En los hombres, el aumento de peso excesivo se asoció con un aumento de TG y TG/HDL-c; en las mujeres, con un aumento mayor en TG/HDL-c y colesterol no HDL. Sin embargo, la variación z-score puede ser un buen predictor de cambios en el perfil lipídico, incluso en aquellos que se encuentran dentro del rango normal.

OBJECTIVE: to evaluate the clinical, surgical, and nutritional profile of surgical patients admitted to a reference hospital in Recife city, Pernambuco state, Brazil. METHODS: a cross-sectional study carried out in the wards of the General Surgery Service of Hospital da Restauração Governador Paulo Guerra, from June to September 2018. We included adult and elderly patients (both genders) who were submitted to thoracoabdominal procedures and elective or emergency abdominal surgeries, and in which the assessment of nutritional status could be performed within 72 hours of hospital admission. Data on nutritional status and surgical procedures, as well as clinical and biochemical information, were collected. RESULTS: we studied 140 patients with median age of 45 years. Among all, 59.3% were female and 23% malnourished, according to Subjective Global Assessment. The median preoperative fasting time was 15 hours for size I surgeries and 13.5 hours for size II ones. Longer postoperative hospital stay showed a strong correlation with the total length of hospital stay in both surgical sizes. Malnourished patients had a longer period of perioperative fasting and hospital stay when compared to well-nourished patients (p<0.001). CONCLUSION: the perioperative fasting time for elective surgeries was longer than recommended by literature. Patients with longer fasting spent more time in hospital.
OBJETIVO: avaliar o perfil clínico, cirúrgico e nutricional de pacientes cirúrgicos internados em um hospital de referência da cidade de Recife - PE. MÉTODOS: estudo de caráter transversal, realizado nas enfermarias do Serviço de Cirurgia Geral do Hospital da Restauração Governador Paulo Guerra, no período de junho a setembro de 2018. Foram incluídos pacientes adultos e idosos de ambos os sexos, submetidos a procedimentos toracoabdominais e cirurgias abdominais, de caráter eletivo ou de emergência, em que a avaliação do estado nutricional pôde ser realizada em até 72 horas da admissão hospitalar. Foram coletados dados sobre o estado nutricional, sobre os procedimentos cirúrgicos, assim como, informações clínicas e bioquímicas. RESULTADOS: foram estudados 140 pacientes, com mediana de idade de 45 anos, 59,3% do sexo feminino, sendo que 23% apresentavam-se desnutridos, através da Avaliação Subjetiva Global. A mediana do tempo de jejum pré-operatório para as cirurgias de porte I foi de 15 horas e para as de porte II, 13,5 horas. Maior tempo de permanência hospitalar no pós-operatório apresentou forte correlação com o tempo total de internamento em ambos os portes cirúrgicos. Pacientes desnutridos apresentaram maior tempo de jejum perioperatório e de permanência hospitalar quando comparados com os bem nutridos (p<0,001). CONCLUSÃO: o tempo de jejum perioperatório das cirurgias eletivas esteve acima do que é preconizado pela literatura. Pacientes com maior tempo de jejum permaneceram mais tempo internados.

Abstract Objective: Evaluate the association between inflammatory process, adiposity, and vitamins A, D, and E in adolescents, according to gender. Methods: Cross-sectional study with adolescents aged 12-19 years old of both genders attending public schools in Recife. A questionnaire was used to collect data on socioeconomic level, lifestyle, and food intake of adolescents. Then, an anthropometric evaluation and a blood sampling were performed to analyze serum concentrations of α-1-acid glycoprotein, retinol, β-carotene, α-tocopherol, and 25-hydroxy-vitamin D. Results: The levels of α-1-acid glycoprotein were higher for abdominal obesity in both genders. Male adolescents with insufficient serum α-tocopherol levels had low levels of α-1-acid glycoprotein (p = 0.03) and an increased risk of 25-hydroxy-vitamin D and β-carotene deficiency in relation to total and abdominal fat; female adolescents had an increased risk of insufficient β-carotene with abdominal obesity (PR: 1.33; 95% CI: 1.2-1.5). Conclusion: Abdominal adiposity implies a higher risk of inflammation and causes different changes to the levels of fat-soluble vitamins according to gender.
Resumo: Objetivo: Avaliar a associação entre processo inflamatório, adiposidade e as vitaminas A, D e E em adolescentes, segundo o sexo. Métodos: Estudo transversal com adolescentes de 12 a 19 anos de ambos os sexos de escolas públicas de Recife. Foi utilizado um questionário para coleta de dados socioeconômicos, de estilo de vida e de consumo alimentar dos adolescentes. Em seguida, realizou-se a avalição antropométrica e coleta de sangue para análise das concentrações séricas de α-1-glicoproteína ácida, retinol, β-caroteno, α-tocoferol e 25-hidroxivitamina D. Resultados: Os níveis de α-1-glicoproteína ácida foram maiores na obesidade abdominal de ambos os sexos. Os meninos com níveis séricos insuficientes de α-tocoferol expressaram níveis reduzidos de α-1-glicoproteína ácida (p = 0,03) e apresentaram um maior risco de deficiência de 25-hidroxivitamina D e β-caroteno na adiposidade total e abdominal, enquanto as meninas mostraram maior risco de insuficiência de β-caroteno com a obesidade abdominal (RP 1,33; IC 95% 1,2-1,5). Conclusão: A adiposidade abdominal reflete maior risco de inflamação e causa alterações distintas nas concentrações das vitaminas lipossolúveis, de acordo com o sexo.

OBJECTIVE: to investigate the impact of bariatric surgery on the coronary artery calcium score (CACS), and to establish predictors of progression of this score in patients with obesity. METHODS: prospective study that evaluated 18 obese patients before and after bariatric surgery. All patients were submitted to computed tomography scans and blood tests (total cholesterol, LDL, HDL, triglycerides, fasting plasma glucose, A1C, insulin, serum calcium, C-peptide and C-Reactive Protein) in order to determine CACS and Framingham risk score (FRS). RESULTS: the FRS decreased 50% between the pre and postoperative evaluations. The mean CACS increased significantly at the late postoperative period, going from 8.5 to 33.1. HDL levels had also increased between the pre and postoperative periods. All of the other quantitative variables reduced significantly at the postoperative evaluation. When dividing CACS into four degrees, it was observed that 22.2% presented CACS=0 at the postoperative evaluation. The prevalence of mild CACS decreased from 77.8% to 50%, while moderate CACS remained the same (11.1%). Severe CACS increased from 11.1% to 16.7%. Older ages were linked to CACS progression, and this was the only variable that presented statistical association with progression. CONCLUSION: bariatric surgery leads to positive cardiovascular outcomes, apparently regardless of CACS.
OBJETIVO: investigar o impacto da cirurgia bariátrica no escore de cálcio coronariano (ECC) e estabelecer fatores preditivos de progressão desse escore em pacientes obesos. MÉTODOS: estudo prospectivo de 18 pacientes obesos antes e depois da cirurgia bariátrica. Todos os pacientes foram submetidos à tomografia computadorizada e a exames laboratoriais com dosagens sanguíneas de colesterol total, LDL, HDL, triglicerídeos, glicose de jejum, A1C, insulina, cálcio sérico, peptídeo C e proteína C-reativa, para determinar o ECC e o escore de risco de Framingham (ERF). RESULTADOS: o ERF reduziu 50% entre as avaliações pré e pós-operatórias. O ECC médio aumentou significativamente no período pós-operatório, aumentando de 8,5 para 33,1. Os níveis de HDL também aumentaram no pós-operatório. Todas as outras variáveis quantitativas reduziram significativamente no pós-operatório. Ao estratificar o ECC em quatro categorias, foi observado que 22,2% da amostra apresentou ECC=0 no pós-operatório. A prevalência de ECC leve reduziu de 77,8% para 50%, enquanto que ECC moderado permaneceu igual no pré e no pós-operatório (11,1%). ECC grave aumentou de 11,1% para 16,7%. Idade avançada foi associada à progressão do ECC, e essa foi a única variável que apresentou correlação estatística com a progressão do ECC. CONCLUSÃO: cirurgia bariátrica produz desfechos cardiovasculares positivos, que, aparentemente, ocorrem de forma independente do ECC.

This study evaluates the relation between consumption of ultraprocessed foods, nutritional status, and dyslipidemia in schoolchildren from Recife/PE, Brazil. This is a cohort study conducted in 2008-2009 and 2012-2013, with 238 students recruited from the public school system of the city of Recife, Northeast Brazil. Demographic data, stage of sexual maturation, socioeconomic, lifestyle, anthropometric, and lipid profiles were collected. There was a high prevalence of overweight, abdominal obesity, and dyslipidemia in both the time periods. The number of teenagers sufficiently active was higher in 2012-2013. There was a positive correlation between the consumption of ultraprocessed foods and age in 2008-2009. In 2008-2009, high consumption of ultraprocessed foods occurred in the majority of adolescents with normal total serum cholesterol values. In 2012-2013, low maternal schooling proved to be an important factor for a lower consumption of ultraprocessed foods. The consumption of ultraprocessed foods showed no direct relationship with overweight, abdominal obesity, and dyslipidemia in adolescents.

Conclusion: bariatric surgery leads to positive cardiovascular outcomes, apparently regardless of CACS.

Hepatocellular adenomas (HCAs) are rare benign monoclonal hepatic tumors that commonly occur in females (3-4 per 100,000 women) due to the use of oral contraceptives, its primary risk factor. Recently, HCAs have been classified into 4 distinct subtypes according to genotypic and phenotypic characteristics and clinical features: inflammatory HCA (40-50%), which are hypervascular with marked peliosis and a tendency to bleed; hepatocyte nuclear factor 1α (HNF1A)-mutated HCA (H-HCA, 30-40%) that are diffusely steatotic and rarely undergo malignant transformation; ß-catenin activated HCA (10-15%), which frequently undergo malignant transformation and may seem hepatocellular carcinoma on imaging; and unclassified HCA (10-25%). In this study, we report the case of a 23-year-old female oral contraceptive user with H-HCA. Usually, H-HCA is considered to be nonsevere in most cases and often requires outpatient follow-up. However, in this case, the injury had substantially increased in volume and evolved with a major bleeding frame, which was an unusual finding for this subtype of adenoma. The therapeutic used for this patient was a laparoscopic left hepatic segmentectomy. Thus, the choice of treatment to be performed in a patient with H-HCA can depend on the tumor size (>5 cm), the outcome of previous bleeding, and the risk of bleeding recurrence.
RESUMO
Fundamentos: A obesidade está associada a alterações estruturais e funcionais do ventrículo esquerdo (VE). A cirurgia bariátrica tem o potencial de reverter tais achados. Os efeitos do procedimento nas funções diastólica e sistólica do VE não foram claramente definidos. O presente estudo teve por objetivo avaliar as alterações na estrutura e funções sistólica e diastólica do ventrículo esquerdo de pacientes obesos que se submeteram à cirurgia bariátrica. Métodos: Foram avaliados 23 pacientes (16 mulheres e 7 homens, com idade média de 32,9 ± 8,9 anos), com índice de massa corporal ≥ 40 kg/m2 , que foram submetidos à derivação gástrica em Y de Roux (RYGB). As avaliações clínicas eecocardiográficas foram realizadas no pré-operatório e em 3 a 7 meses após a cirurgia. Resultados: Após período médio de seguimento de 4,7 meses, foram observadas reduções significativas no índice de massa corporal (de 46,7 ± 5,3 para 36,2 ± 4,7 kg/m2 ; p < 0,001); na espessura do septo interventricular(de 10,3 ± 1,4 para 8,9 ± 1,2 mm); na parede posterior do VE (de 9,3 ± 1,3 para 8,4 ± 1,1 mm; p < 0,001) e na massa do VE (valor absoluto: de 168,7 ± 35,2 para 149,8 ± 40,7 g, p = 0,008; indexada pela altura: de 45,1 ± 11,3 para 39,7 ± 10,3, p = 0,006). A geometria normal do VE foi observada em 60,9% dos pacientes antes da cirurgia e em 91,3% no período de seguimento. O Doppler tecidual revelou melhora na função diastólica do VE (velocidade de onda E mitral lateral, 0,16 ± 0,03 no pré-operatório contra 0,17 ± 0,03 m/s no seguimento; p = 0,026). No pós‑operatório, não houve diferença significativa na função sistólica do VE. Conclusões: Após um seguimento médio de 4,7 meses, a cirurgia bariátrica promoveu melhora na estrutura ventricular esquerda e em um dos parâmetros da função diastólica (velocidade de E). Não houve alterações nos parâmetros sistólicos do ventrículo esquerdo.
Background: Obesity is associated with changes in left ventricular (LV) structure and function. Bariatric surgery can favorably improve cardiac remodeling. The effects of the procedure in LV diastolic and systolic function have not been clearly defined. The aim of this study was to evaluate the changes in left ventricular structure, systolic and diastolic function in obese patients who have undergone bariatric surgery.Methods: We evaluated 23 patients (16 women, seven men; age, 32.9 ± 8.9 years) with body mass index > 40 kg/m2 who underwent Roux-en-Y gastric bypass (RYGB). Clinical and echocardiographic evaluations were performed preoperatively and 37 months after surgery. Results: After a mean follow-up of 4.7 months, significant reductions were observed in body mass index (from 46.7 ± 5.3 to 36.2 ± 4.7 kg/m2; p< 0.001); thickness of the interventricular septum (from 10.3 ± 1.4 to 8.9 ± 1.2 mm); LV posterior wall (from 9.3 ± 1.3 to 8.4 ± 1.1mm; p < 0.001) and LV mass (absolute value: from 168.7 ± 35.2 to 149.8 ± 40.7 g, p = 0.008; indexed by height: from 45.1 ± 11.3 to 39.7 ± 10.3, p = 0.006). Normal LV geometry was observed in 60.9% of patients before surgery and in 91.3% at follow-up. Tissue Doppler imaging revealed improved LV diastolic function (mitral E lateral 0.16 ± 0.03 preoperatively vs. 0.17 ± 0.03 m/s at follow-up; p = 0.026). Postoperatively, there was no significant difference in LV systolic function. Conclusions: After a mean follow-up of 4,7 months, bariatric surgery promoted improvement in left ventricular structure and in one of the parameters of diastolic function (E velocity). There were no changes in left ventricular systolic parameters.

Objective. This prospective open trial aimed to evaluate the efficacy and safety of isotretinoin (13-cis-retinoic acid) in patients with Cushing's disease (CD). Methods. Sixteen patients with CD and persistent or recurrent hypercortisolism after transsphenoidal surgery were given isotretinoin orally for 6-12 months. The drug was started on 20 mg daily and the dosage was increased up to 80 mg daily if needed and tolerated. Clinical, biochemical, and hormonal parameters were evaluated at baseline and monthly for 6-12 months. Results. Of the 16 subjects, 4% (25%) persisted with normal urinary free cortisol (UFC) levels at the end of the study. UFC reductions of up to 52.1% were found in the rest. Only patients with UFC levels below 2.5-fold of the upper limit of normal achieved sustained UFC normalization. Improvements of clinical and biochemical parameters were also noted mostly in responsive patients. Typical isotretinoin side-effects were experienced by 7 patients (43.7%), though they were mild and mostly transient. We also observed that the combination of isotretinoin with cabergoline, in relatively low doses, may occasionally be more effective than either drug alone. Conclusions. Isotretinoin may be an effective and safe therapy for some CD patients, particularly those with mild hypercortisolism.
RESUMO
Successful discontinuation of cabergoline (CAB) treatment has been reported in 31-75% of prolactinomas patients treated for at least 2 years. In contrast, it is not well established whether CAB therapy can be successfully withdrawn after a failed first attempt. This prospective open trial was designed to address this topic and to try to identify possible predictor factors. Among 180 patients with prolactinomas on CAB therapy, the authors selected those who fulfilled very strict criteria, particularly additional CAB therapy for at least 2 years, normalization of serum prolactin (PRL) levels following CAB restart, no tumor remnant >10 mm, no previous pituitary radiotherapy or surgery; and current CAB dose ≤1.0 mg/week. Recurrence was defined as an increase of PRL levels above the upper limit of normal. A total of 34 patients (70.6% female) treated with CAB for 24-30 months were recruited. Ten patients (29.4%) remained without evidence of recurrence after 24-26 months of follow-up. Twenty-four patients (70.6%) recurred within 15 months (75% within 12 months) after drug withdrawal and ~80% were restarted CAB. Median time to recurrence was 10.5 months (range, 3-15). Despite overlapping values, non-recurring patients had significantly lower mean PRL levels before withdrawal. Moreover, the recurrence rate was lower in subjects without visible tumor on pituitary magnetic resonance imaging (MRI) than in those with small remnant tumor (60 vs. 79%), though the difference was not statistically significant (P = 0.20). No other characteristic could be identified as a predictor of successful CAB discontinuation. In conclusion, a second attempt of CAB withdrawal after two additional years of therapy may be successful, particularly in patients with lower PRL levels and no visible tumor on pituitary MRI. Close monitoring of PRL level is mandatory, especially within the first year after withdrawal, where most recurrences are detected.
RESUMO
Cushing's disease (CD) is usually caused by secretion of ACTH by a pituitary corticotroph microadenoma. Nevertheless, 7%-20% of patients present with ACTH-secreting macroadenomas. Our aim is to report a 36-year-old female patient with CD due to solid-cystic ACTH-macroadenoma followed up during 34 months. The patient presented spontaneous remission due to presumed asymptomatic tumor apoplexy. She showed typical signs and symptoms of Cushing's syndrome (CS). Initial tests were consistent with ACTH-dependent CS: elevated urinary free cortisol, abnormal serum cortisol after low dose dexamethasone suppression test, and elevated midnight salivary cortisol, associated with high plasma ACTH levels. Pituitary magnetic resonance imaging (MRI) showed a sellar mass of 1.2 x 0.8 x 0.8 cm of diameter with supra-sellar extension leading to slight chiasmatic impingement, and showing hyperintensity on T2-weighted imaging, suggesting a cystic component. She had no visual impairment. After two months, while waiting for pituitary surgery, she presented spontaneous resolution of CS. Tests were consistent with remission of hypercortisolism: normal 24-h total urinary cortisol and normal midnight salivary cortisol. Pituitary MRI showed shrinkage of the tumor with disappearance of the chiasmatic compression. She has been free from the disease for 28 months (without hypercortisolism or hypopituitarism). The hormonal and imaging data suggested that silent apoplexy of pituitary tumor led to spontaneous remission of CS. However, recurrence of CS was described in cases following pituitary apoplexy. Therefore, careful long-term follow-up is required.

A doença de Cushing (DC) é usualmente causada por um microadenoma produtor de ACTH. Entretanto, 7%-20% dos pacientes apresentam um macroadenoma. O objetivo deste trabalho é reportar uma paciente de 36 anos, feminina, com diagnóstico de DC devido a macroadenoma hipofisário sólido-cístico com seguimento de 34 meses que apresentou remissão espontânea presumidamente em decorrência de uma apoplexia tumoral assintomática. Inicialmente, ela apresentava sinais e sintomas típicos da síndrome de Cushing (SC). Na admissão, os testes foram consistentes com o diagnóstico de SC ACTH-dependente: cortisol urinário livre de 24h elevado, não supressão do cortisol sérico após dose baixa de dexametasona e cortisol salivar noturno elevado, associado a concentrações elevadas do ACTH plasmático. Ressonância magnética (RM) de hipófise revelou uma massa selar de 1.2 x 0.8 x 0.8 cm com extensão suprasselar levando a uma discreta compressão do quiasma óptico e mostrando região de hipersinal na imagem ponderada em T2 sugerindo um componente cístico. A paciente não apresentava queixas visuais. Após dois meses, enquanto aguardava o tratamento cirúrgico, a paciente apresentou remissão espontânea da SC. A repetição dos exames indicou remissão do hipercortisolismo: normalização do cortisol urinário livre de 24h e normalização do cortisol salivar noturno. Nova RM de hipófise revelou redução do volume tumoral com desaparecimento da compressão quiasmática. A paciente permanece livre da doença por 28 meses (sem hipercortisolismo ou hipopituitarismo). Os dados hormonais e de imagem sugerem que tenha ocorrido uma apoplexia tumoral assintomática, levando à remissão espontânea da SC. Entretanto, como há relatos de recorrência após apoplexia hipofisária, cuidadoso seguimento a longo prazo faz-se necessário.
