OBJECTIVE@#To investigate the coagulation function indicators and identify influence factors of hypercoagulability in patients with adrenocorticotropic hormone (ACTH) independent Cushing syndrome (CS).@*METHODS@#In our retrospective study, the electronic medical records system of Peking University First Hospital was searched for the patients diagnosed with ACTH independent CS on discharge from January 2014 to June 2019. Nonfunctional adrenal adenoma patients were chosen as control group and matched 1 ∶1 by body mass index (BMI), gender, and discharge date. Clinical features and coagulation function indicators were compared between the two groups.@*RESULTS@#In the study, 171 patients were included in each group. Compared with control group, activated partial thromboplastin time (APTT), and prothrombin time (PT) in ACTH independent CS group were significantly lower [(29.22±3.39) s vs. (31.86±3.63) s, P < 0.001; (29.22±3.39) s vs. (31.86±3.63) s, P < 0.001], and both D-dimer and fibrin degradation products (FDP) levels were significantly higher (P < 0.05). Percentage of APTT levels under the lower limit of reference range in the CS patients was significantly higher than that in nonfunctional group (21.6% vs. 3.5%, P < 0.001). Percentage of D-dimer levels over the upper limit of reference range in the CS patients was significantly higher than that in nonfunctional group (13.5% vs. 6.6%, P=0.041). There were three patients with deep venous thrombosis and one patient with pulmonary embolism in CS group, however none was in control group. The area under curve (AUC) of serum cortisol rhythm (8:00, 16:00 and 24:00) levels was negatively associated with the levels of PT (r=-0.315, P < 0.001) and APTT (r=-0.410, P < 0.001), and positively associated with FDP (r=0.303, P < 0.001) and D-dimer levels (r=0.258, P < 0.001). There were no differences in coagulation function indicators among different histopathologic subgroups (adrenocortical adenoma, adrenocortical hyperplasia, oncocytic adenoma, adrenocortical carcinoma). With Logistic regression analysis, the AUC of cortisol and glycosylated hemoglobin A1c (HbA1c) levels were independent risk factors for hypercoagulability in the ACTH independent CS patients (P < 0.05).@*CONCLUSION@#ACTH independent CS patients were more likely in hypercoagulable state compared with nonfunctional adrenal adenoma, especially in ACTH independent CS patients with higher levels of cortisol AUC and HbA1c. These patients should be paid attention to for the hypercoagulability and thrombosis risk.

Resumen: Presentamos un caso de una paciente femenina de 27 años, con síndrome de Cushing ACTH dependiente con hipercortisolismo severo, causado por un macroadenoma hipofisario recurrente y resistente pese a dos cirugías transesfenoidales, radioterapia y terapia médica. Dada la falla en las diferentes terapias se realiza una adrenalectomía bilateral como tratamiento definitivo. La paciente fallece en el posoperatorio por causa no clara. Si bien la adrenalectomía bilateral ha sido reportada como un tratamiento efectivo en pacientes con enfermedad de Cushing, se ha relacionado con una mortalidad significativa vinculada con la severidad del hipercortisolismo y las comorbilidades presentes. En este caso la adrenalectomía izquierda se tuvo que convertir a cielo abierto, asociada con mayor morbimortalidad.

Abstract: The study presents the case of a 27-year-old female patient with adrenocorticotropic hormone (ACTH) dependent Cushing's disease and severe hypercortisolism caused by recurrent pituitary macroadenoma that was resistant to treatment despite two transsphenoidal surgeries, radiotherapy and medical treatment. Upon failure of the different therapies a bilateral adrenalectomy was performed as the final treatment. The patient died in after surgery although the case of death was not clear. Despite bilateral adrenalectomy having been reports as an effective treatment in patients with Cushing's disease, it has been related to significant mortality rates in connection with the severity of hypercortisolism and existing comorbilities. In this case the left adrenalectomy ended up being an open surgery, which is associated to a higher mortality rate.

Resumo: Apresentamos o caso de uma paciente de 27 anos com síndrome de Cushing ACTH-dependente com hipercortisolismo grave causado por macroadenoma hipofisário, recorrente e resistente, apesar de haver sido submetida a duas cirurgias transesfenoidal, radioterapia e terapia medicamentosa. Diante do fracasso das diferentes terapias, foi realizada adrenalectomia bilateral como tratamento definitivo. A paciente faleceu no pós-operatório por causa não esclarecida. Embora a adrenalectomia bilateral tenha sido relatada como tratamento eficaz em pacientes com doença de Cushing, ela tem sido associada a mortalidade significativa relacionada à gravidade do hipercortisolismo e às comorbidades presentes. Neste caso, a adrenalectomia esquerda teve que ser convertida para cirurgia aberta, associada a maior morbimortalidade.

SUMMARY We report a rare case of Cushing's syndrome in a 37-year-old female who initially presented with localized acinic cell carcinoma of the parotid gland. In January 2014, she underwent a right parotidectomy with facial nerve preservation and adjuvant radiotherapy. In August 2018, she presented a histologically-proven local regional relapse. The patient was considered for salvage surgery with facial nerve sacrifice and remained with no evidence of disease. One year later the patient developed pulmonary dissemination and started to gain weight and developed facial plethora and acne on the face and upper trunk. In a physical examination, the patient presented moon face, buffalo hump, acne and stage 2 hypertension. Biochemical evaluation confirmed ACTH-dependent Cushing's syndrome. IHC for ACTH in the lung biopsy revealed strong positive staining for ACTH confirming a diagnosis of ectopic ACTH secretion by a metastatic parotid acinic cell carcinoma. Ketoconazole (600 mg/d) was started to treat the CS. In addition, as chemotherapy was initiated to treat the metastatic disease. After the fifth cycle of chemotherapy, ketoconazole was suspended and the patient remained in remission of CS for four months, when CS recurred. A unique feature of this case is related to the clinical CS relapse associated with disease progression, which needed prompt treatment with ketoconazole, resulting in a significant improvement in the patient's condition. Although rare, should be attentive for possible CS features in patients with high-grade salivary gland carcinomas, since the diagnosis of ectopic secretion of ACTH may significantly impact their management and outcomes.

Objective: To investigate the characteristics and comprehensive treatment of infected wounds in patients with iatrogenic Cushing's syndrome. Methods: A retrospective observational study was conducted. From May 2012 to December 2021, the data of 19 patients with iatrogenic Cushing's syndrome discharged from the Department of Burns and Plastic Surgery of the First Affiliated Hospital of Guangxi Medical University were collected, including 8 males and 11 females, aged 28-71 (56±11) years, with 12 cases of infected acute wounds and 7 cases of infected chronic wounds. The lesions were located in the limbs, perianal, and sacrococcygeal regions, with original infection ranging from 9 cm×5 cm to 85 cm×45 cm. After admission, the patients were performed with multidisciplinary assisted diagnosis and treatment, and the wounds were treated with debridement and vacuum sealing drainage, according to the size, severity of infection, suture tension, and bone and tendon tissue exposure of wounds, direct suture or autologous skin and/or artificial dermis and/or autologous tissue flap transplantation was selected for wound repair. The levels of cortisol and adrenocorticotropic hormone (ACTH) of patients at 8:00, 16:00, and 24:00 within 24 h after admission were counted. After admission, the number of operations, wound repair methods, and wound and skin/flap donor site healing of patients were recorded. During follow-up, the wounds were observed for recurrent infection. Results: The cortisol levels of 16 patients at 8:00, 16:00, and 24:00 within 24 h after admission were (130±54), (80±16), and (109±39) nmol/L, respectively, and ACTH levels were (7.2±2.8), (4.1±1.8), and (6.0±3.0) pg/mL, respectively; and the other 3 patients had no such statistical results. After admission, the number of surgical operation for patients was 3.4±0.9. The following methods were used for wound repair, including direct suturing in 4 cases and autologous skin and/or artificial dermis grafting in 9 cases, of which 2 cases underwent stage Ⅱ autologous skin grafting after artificial dermis grafting in stage Ⅰ, and 6 cases had pedicled retrograde island flap+autologous skin grafting. The wound healing was observed, showing that all directly sutured wounds healed well; the wounds in 6 cases of autologous skin and/or artificial dermis grafting healed well, and the wounds in 3 cases also healed well after the secondary skin grafting; the flaps in 4 cases survived well with the wounds in 2 cases with distal perforators flap arteries circumfluence obstacle of posterior leg healed after stage Ⅱ debridement and autologous skin grafting. The healing status of skin/flap donor sites was followed showing that the donor sites of medium-thickness skin grafts in the thigh of 4 cases were well healed after transplanted with autologous split-thickness grafts from scalp; the donor sites of medium-thickness skin grafts in 3 cases did not undergo split-thickness skin grafting, of which 2 cases had poor healing but healed well after secondary skin grafting 2 weeks after surgery; the donor sites of split-thickness skin grafts in the head of 2 patients healed well; and all donor sites of flaps healed well after autologous skin grafting. During follow-up of more than half a year, 3 gout patients were hospitalized again for surgical treatment due to gout stone rupture, 4 patients were hospitalized again for surgical treatment due to infection, and no recurrent infection was found in the rest of patients. Conclusions: The infected wounds in patients with iatrogenic Cushing's syndrome have poor ability to regenerate and are prone to repeated infection. Local wound treatment together with multidisciplinary comprehensive treatment should be performed to control infection and close wounds in a timely manner, so as to maximize the benefits of patients.

Los corticoesteroides tópicos son drogas muy comunes, frecuentemente utilizadas en patologías dermatológicas. Su mal uso puede causar efectos sistémicos, como el síndrome de Cushing y la supresión del eje hipotalámico ­ hipofisiario ­ adrenal. Presentamos un caso de un lactante menor de siete meses quien desarrolla un síndrome de Cushing secundario al uso de Clobetasol por una dermatitis en el área del pañal, por tiempo prolongado, sin prescripción médica. Al examen físico se evidencia obesidad a predominio central, con fascie de luna llena, hipertricosis en región frontal, telangiectasias aisladas en mejillas y cuello de búfalo. Los paraclínicos demuestran una hipercolesterolemia, hipertrigliceridemia, elevación de las transaminasas y cortisol sérico en la mañana disminuido. Se concluye que se debe informar a los padres de los efectos adversos sistémicos de los esteroides tópicos y se sugiere evitar en pacientes pediátrico(AU)

Topical corticosteroids are very common drugs used in the treatment of inflammatory skin diseases. Prolonged ormisuse of them may cause systemic adverse effects, including Cushing syndrome and hypothalamic-pituitary-adrenal axissuppression. We present a case of a seven months old maleinfant who developed iatrogenic Cushing syndrome after diaperdermatitis treatment through misuse of Clobetasol, withoutdoctor's prescription. We observe redness and a moon face, abuffalo hump, central obesity and hirsutism. Laboratory values revealed hypercholesterolemia, hypertriglyceridemia, elevationin liver enzymes and low early morning cortisol. To conclude,parents must be informed by physicians about the adverse effect of steroids and the should be avoided in very young infant(AU)

SUMMARY Cyclic Cushing's syndrome (CS) due to thymic carcinoid is a rare disorder. We report a case of cyclic CS due to ectopic adrenocorticotropic hormone (ACTH)-secreting atypical thymic carcinoid tumor and reviewed similar cases published in the literature. Our patient had hypercortisolemia lasting approximately one month, followed by normal cortisol secretion, with relapse one year later. Histopathology revealed an atypical ACTH-positive thymic carcinoid. Ectopic CS can be derived from atypical thymic carcinoids, which can be aggressive tumors with early relapse, suggesting that this type of tumor probably needs aggressive treatment.

SUMMARY Carney complex (CNC) is a rare syndrome of multiple endocrine and non-endocrine tumors. In this paper we present a 23-year-old Iranian woman with CNC who harbored a novel mutation (c.642dupT) in PRKAR1A gene. This patient presented with pituitary macroadenoma, acromegaly, recurrent atrial myxoma, Cushing's syndrome secondary to primary pigmented nodular adrenocortical disease and pigmented schwanoma of the skin. PRKAR1A gene was PCR amplified using genomic DNA and analyzed for sequence variants which revealed the novel mutation resulting in substitution of amino acid cysteine instead of the naturally occurring valine in the peptide chain and a premature stop codon at position 18 (V215CfsX18). This change leads to development of tumors in different organs due to lack of tumor suppressive activity secondary to failure of synthesis of the related protein.

Introducción: El diagnóstico clínico del hipercortisolismo endógeno puede ser complejo si las manifestaciones clínicas no son patognomónicas. Es importante conocer cuáles son las distintivas en nuestros pacientes, que permitan diagnosticar la enfermedad de forma precoz. Objetivo: Determinar sensibilidad, especificidad y valor predictivo positivo de las manifestaciones clínicas para diagnosticar el hipercortisolismo endógeno. Métodos: Estudio descriptivo transversal. Grupo I: 65 pacientes con hipercortisolismo endógeno y grupo II (comparación): 75 con sospecha clínica de hipercortisolismo endógeno a los que se les descartó la enfermedad. Se estudiaron pacientes con diagnóstico de hipercortisolismo endógeno (2004-2017), atendidos en el Instituto de Endocrinología. Se determinaron los valores de sensibilidad, especificidad y valor predictivo positivo para el diagnóstico de hipercortisolismo endógeno de cada síntoma y signo por separado, así como para las combinaciones de tres manifestaciones clínicas; además se realizó una regresión logística binaria para identificar las combinaciones de sintomatologías que mejor predicen la presencia de hipercortisolismo endógeno. Se consideró diferencia estadística significativa con p ≤ 0,05. Resultados: La mayoría de los síntomas presentó una sensibilidad inferior al 45 por ciento. La circunferencia de la cintura fue el único signo que mostró alta sensibilidad (76,9 por ciento), baja especificidad (28,6 por ciento) con valor predictivo positivo de 42,0 por ciento. Cuando se presentan dos o tres de estos signos: rubicundez, cara de "luna llena" e hirsutismo la posibilidad de tener hipercortisolismo endógeno es 75,4 por ciento, con valor predictivo positivo de 71 por ciento y, cuando no están presentes la probabilidad de no tenerlo es de 77,5 por ciento. Conclusiones: La combinación de sensibilidad, especificidad y valor predictivo positivo de los síntomas y signos de forma aislada no predice el diagnóstico de la enfermedad; sin embargo, la presencia de dos o tres de los síntomas y/o signos tiene una elevada sensibilidad y valor predictivo positivo para el diagnóstico del hipercortisolismo endógeno. Las combinaciones que mejor predicen la posibilidad de tener un hipercortisolismo endógeno son: piel fina, edema y acné; cara de "luna llena", hirsutismo y rubicundez, así como "giba de búfalo", hematomas y estrías(AU)

ABSTRACT Introduction: The clinical diagnosis of endogenous hypercortisolism can be complex if clinical manifestations are not pathognomonic. It is important to know what are distinctive in our patients, which allows to diagnose the disease early. Objective: To determine the sensitivity, specificity and positive predictive value of clinical manifestations for diagnosis. of endogenous hypercortisolism. Methods: Descriptive and cross-sectional study. Group I was made up of 65 patients with endogenous hypercortisolism; group II (comparison) was made up of 75 patients with clinical suspicion of endogenous hypercortisolism, finally ruled out. We studied patients diagnosed of endogenous hypercortisolism from 2004 to 2017, treated at the Endocrinology Institute. Sensitivity, specificity and positive predictive values were determined for the diagnosis of endogenous hypercortisolism for each symptom and sign separately, as well as for the combinations of three clinical manifestations; in addition, binary logistic regression was performed to identify the combinations of symptoms that best predict the presence of endogenous hypercortisolism. A statistically significant difference was considered with p ≤ 0.05. Results: Most of the symptoms presented a sensitivity lower than 45 percent. Waist circumference was the only sign that showed high sensitivity (76.9 percent), low specificity (28.6 percent), and positive predictive value of 42.0 percent. When two or three of these signs (redness, "full-moon" face, and hirsutism) are present, the possibility of having endogenous hypercortisolism is 75.4 percent, with positive predictive value of 71 percent; and, when they are not present, the probability of not having it is 77,5 percent. Conclusions: The combination of sensitivity, specificity and positive predictive value of the symptoms and signs in isolation does not predict the diagnosis of the disease; however, the presence of two or three of the symptoms and/or signs has a high sensitivity and positive predictive value for the diagnosis of endogenous hypercortisolism. The combinations that best predict the possibility of having an endogenous hypercortisolism are thin skin, edema and acne; "full-moon" face, hirsutism and redness; as well as "buffalo hump," bruises and stretch marks(AU)

Resumen: Identificar la causa de un síndrome de Cushing dependiente de adrenocorticotropina (ACTH) es esencial para realizar un tratamiento correcto. La hipersecreción de ACTH es debida en su mayoría a un tumor hipofisario (enfermedad de Cushing) o, en un 10%-20%, a tumores con producción ectópica de esta hormona. Los test no invasivos tienen baja sensibilidad y especificidad para diferenciar estas dos etiologías. El patrón oro lo constituye el cateterismo bilateral de los senos petrosos inferiores (CSP). Mediante el CSP se demuestra la hipersecreción de ACTH a nivel hipofisario al documentar un gradiente de ACTH central a periférico en el drenaje del tumor. Se recomienda realizarlo en todo síndrome de Cushing ACTH dependiente, aunque suele reservarse para pacientes con diagnóstico de hipercortisolismo y hallazgos negativos o equívocos en la resonancia nuclear magnética (RNM) de la región selar. Presentamos el primer caso en Uruguay en que se utilizó el CSP como método diagnóstico, una mujer de 55 años que presentó un hipercortisolismo ACTH-dependiente con una imagen adenohipofisaria <6 mm. El gradiente petroso-periférico confirmó el diagnóstico de enfermedad de Cushing y no hubo complicaciones durante el procedimiento. Posteriormente se realizó la resección del adenoma mediante cirugía transesfenoidal, con buena evolución y confirmación inmunohistoquímica del tumor.

Summary: Identifying the cause of adrenocorticotropin (ACTH)-dependent Cushing's syndrome is key to define the appropriate treatment. Hypersecretion of the adrenocorticotropic hormone (ACTH) is mainly caused by a pituitary tumor (Cushing's syndrome) or, in 10% to 20% of cases, by tumors with ectopic production of this hormone. Differentiation between these two etiologies may not be easy due to the low sensitivity and specificity of non- invasive tests. Bilateral sampling of the lower petrosal sinus is the gold standard to differentiate between a pituitary and an ectopic origin, showing the pituitary ACHT hypersecretion and recording the central-to-peripheral ACTH gradient in the tumor's drainage. Despite it being highly recommended for all cases of ACTH-dependent Cushing's syndrome, it is reserved for patients with a diagnosis of hypercortisolism and negative or misleading findings in the MRI of the sellar region. The study presents the first case of petrosal sinus sampling for diagnostic purposes in Uruguay, in a 55-year-old woman with ACHT-dependent hypercortisolism showing an adenohypophysis image < 6 mm. The petrosal-peripheral gradient confirmed the diagnosis of Cushing's syndrome and no complications arose during the procedure. Afterwards a transsphenoidal surgery was performed for resection of the adenoma. Evolution was good and immunochemistry confirmed the tumor's etiology.

A hipersecreção de ACTH se deve principalmente a um tumor hipofisário (doença de Cushing) ou, em 10%-20%, a tumores com produção ectópica desse hormônio. Os testes não invasivos apresentam baixa sensibilidade e especificidade para diferenciar essas duas etiologias. O padrão ouro é o cateterismo bilateral dos seios petrosos inferiores (CEP). O CSP demonstra hipersecreção de ACTH no nível da hipófise, documentando um gradiente de ACTH central a periférico na drenagem do tumor. É recomendado nos casos de síndrome de Cushing dependente de ACTH, embora seja geralmente reservado para pacientes com diagnóstico de hipercortisolismo e achados negativos ou duvidosos na ressonância magnética (RNM) da região selar. Apresentamos o primeiro caso no Uruguai em que o CSP foi usado como método diagnóstico, uma mulher de 55 anos que apresentava hipercortisolismo ACTH dependente com imagem da hipófise anterior <6 mm. O gradiente petroso-periférico confirmou o diagnóstico de doença de Cushing e não houve complicações durante o procedimento. A seguir, o adenoma foi ressecado por cirurgia transesfenoidal, com boa evolução e confirmação imunohistoquímica do tumor.

RESUMEN Mycobacterium abscessus es una micobacteria no tuberculosa de crecimiento rápido, que produce infección pulmonar, cutánea, diseminada y otras, sobre todo en pacientes con comorbilidades. El diagnóstico se basa en la identificación de la micobacteria por medios de cultivo o por pruebas moleculares. El tratamiento con macrólidos y amikacina continúa siendo el ideal, aunque depende de la localización y de la gravedad de la infección, sin embargo, se han identificado genes de resistencia en algunas subespecies que limitan la eficacia antibiótica. Presentamos el caso de un paciente con coinfección cutánea por Mycobacterium abscessus y Mycobacterium tuberculosis, quien presenta un síndrome de Cushing exógeno, factor predisponente para estas infecciones. Además, se identificaron hidatidosis y aspergilosis pulmonares. El tratamiento antituberculoso del paciente se ajustó para manejar ambas micobacterias, y su evolución fue favorable.

ABSTRACT Mycobacterium abscessus is a fast-growing non-tuberculous mycobacterium that causes lung, skin, disseminated and other infections, mainly in patients with comorbidities. The diagnosis is based on the identification of the mycobacterium by culture media or molecular tests. Treatment with macrolides and amikacin remains the optimal choice, although it depends on the location and severity of the infection; however, resistance genes have been identified in some subspecies that limit antibiotic efficacy. We present the case of a patient with cutaneous coinfection by Mycobacterium abscessus and Mycobacterium tuberculosis, who presented exogenous Cushing syndrome, a predisposing factor for these infections. In addition, hydatidosis and pulmonary aspergillosis were identified. The patient's anti-tuberculosis treatment was adjusted to manage both mycobacteria, resulting in a favorable evolution.

ABSTRACT Objective The aim was to describe the clinical features of patients with ectopic Cushing syndrome (ECS) from Colombia and compare these findings with other series to provide the best management for these patients. Materials and methods Records of patients with ECS from 1986 to 2017 were retrospectively reviewed; patients with a diagnosis of adrenal or pituitary Cushing syndrome (CS) were excluded. Results Fourteen patients with ECS were analyzed in this study. The mean age was 54.4 (SD 17.1) years, and the female to male ratio was 1.33:1. Regarding the etiology of ECS, four patients had lung carcinoids (28.6%), three had small-cell lung carcinoma (21.4%), three had pancreatic neuroendocrine tumors (21.4%), one had medullary thyroid cancer (7.1%), one had non-metastatic pheochromocytoma (7.1%), one had metastatic thymoma (7.1%) and one patient had an occult source of ACTH (7.1%). The most common clinical features at presentation were moon-face, muscle weakness, diabetes mellitus and hypertension. Hyperpigmentation was present in 36% of patients, and 12 patients had hypokalemia with a mean value of 2.3 mEq/L (SD 0.71). The median basal cortisol, 24-hour urinary free cortisol (UFC) and ACTH were 30.5 ug/dL (IQR 21-59 ug/dL), 2,600 ug/24 h (IQR 253-6,487 ug/24 h) and 91 pg/mL (IQR 31.9-141.9), respectively. Thirteen patients (92.8%) had the site of the primary lesion identified. Six patients had undergone a surgical intervention to address the primary tumor. Resection was curative in 28.5% of patients. Death occurred in 57.1% of patients, and the median overall survival was 27 months. Intrathoracic tumors had the most aggressive behavior. Conclusions ECS is a rare disease; however, it is associated with high morbidity and mortality. A rapid intervention supported by an interdisciplinary group is required to improve overall survival and quality of life

Abstract Objectives: to analyze, evaluate and describe the usefulness of petrosal sinus sampling for diagnosing central Cushing's syndrome. Materials and methods: the technical aspects and results of bilateral venous sampling of the petrosal sinuses at the Hospital Universitario San Vicente de Paul in Medellín, Colombia, from January 1, 2012 to December 31, 2018, were analyzed. Results: the average age was 43.3 years, with a range from 19 to 69 years. Laterality could be shown in 68.2% of cases, with a tendency to be located on the left in 53.3%. The central source of ACTH production could be shown in 95.4% of cases, with a basal average central/peripheral ratio of 21.7, and 70.8 after stimulation. All samples at 3, 5 and 10 minutes were confirmatory following stimulation. Conclusion: in our retrospective study, petrosal sinus catheterization provided laboratory confirmation of the central source of ACTH production in a high percentage of patients, with no immediate complications.

Resumen Objetivos: analizar, evaluar y describir la utilidad del muestreo de senos petrosos para diagnóstico del síndrome de Cushing de origen central. Material y métodos: se analizaron los aspectos técnicos y resultados del muestreo bilateral venoso de senos petrosos, desde el 1° de enero de 2012 a 31 de diciembre de 2018 en el Hospital Universitario San Vicente de Paúl en Medellín, Colombia. Resultados: el promedio de edad fue 43.3 años con un rango de edad desde los 19 hasta los 69 años. La lateralidad pudo ser demostrada en 68.2% de los casos con una tendencia a la localización en el lado izquierdo en 53.3%. El origen central de producción de ACTH logró ser demostrado en 95.4% de los casos, con una relación central/periferia basal promedio de 21.7 y postestimulación de 70.8. Todas las muestras a los 3, 5 y 10 minutos fueron confirmatorias tras la estimulación. Conclusión: en nuestro estudio retrospectivo el cateterismo de senos petrosos confirmó la fuente central de producción de ACTH por laboratorio en un alto porcentaje de pacientes sin ninguna complicación inmediata.

We report a previously healthy 34-year-old woman, presenting with a seven-month history of arterial hypertension, amenorrhea, weight gain, facial edema, acne, hirsutism and low back pain. A CT scan showed a right adrenal mass of 18 × 13 × 12.5 cm, and multiple vertebral and rib fractures. The hormonal study confirmed Cushing's Syndrome. Ketoconazole, spironolactone, cotrimoxazole, calcium / vitamin D were started. An adrenalectomy with a right nephrectomy were performed. The excised tumor measured 16 cm and weighed 1.55 kg. There was tumor embolism and a 4 mm soft tissue involvement (pT3NxMx). The right kidney was free of tumor. The patient was treated with chemotherapy (etoposide plus cisplatin). Study of vertebral fractures with magnetic resonance (MRI) showed crush fractures, without images of metastatic bone lesions. One year after surgery, a CT scan showed no signs of tumor recurrence. The patient was lost from follow-up thereafter.

Resumen Introducción: el síndrome de Cushing (SC) es un grupo de signos y síntomas causados por la exposición crónica al exceso de glucocorticoides. El uso de fármacos con glucocorticoides es la causa más frecuente, pero algunos productos vendidos como suplementos nutricionales o medicamentos naturistas para el control de los dolores articulares pueden contenerlos de forma oculta, lo cual dificulta el enfoque diagnóstico Presentación del caso: paciente de 40 años con signos clínico típicos de síndrome de Cushing con resultados discordantes en las pruebas diagnósticas para identificar su origen. Finalmente se logra establecer que el paciente consumía de forma crónica un producto "naturista" conocido como artrin®, el cual fue analizado en el laboratorio de la institución con resultados positivos para cortisol. Conclusión: la exposición crónica a glucocorticoides exógenos, ya sea subrepticia, desconocida o prescrita, causa SC y debe distinguirse tempranamente de las formas endógenas para evitar la realización de pruebas diagnósticas y tratamientos inadecuados.(Acta Med Colomb 2020; 45.

Abstract Introduction: Cushing's syndrome (CS) is a group of signs and symptoms caused by chronic exposure to excessive glucocorticoids. The use of medications containing glucocorticoids is the most common cause, but they may be hidden in some products sold as nutritional supplements or naturopathic medications, which makes the diagnostic approach more difficult. Case presentation: this was a 40-year-old patient with typical clinical signs of Cushing's syndrome and discordant results of diagnostic tests to identify its origin. It was ultimately determined that the patient had been chronically taking a "naturopathic" product known as artrin®, which was analyzed in the institution's lab and found to contain cortisol. Conclusion: chronic exposure to exogenous glucocorticoids, whether surreptitious, unknown or prescribed, causes CS and should be promptly distinguished from endogenous forms to avoid inappropriate diagnostic tests and treatments.(Acta Med Colomb 2020; 45.

El incremento de la expectativa de vida con el advenimiento de la terapia antirretroviral de alta eficacia plantea desafíos en cuanto a la toxicidad e interacciones medicamentosas. El síndrome de Cushing exógeno por interacción entre ritonavir y fluticasona inhalada en niños con diagnóstico de infección por virus de la inmunodeficiencia humana y patología pulmonar crónica es infrecuente. Hasta el momento, hay 20 casos reportados. Se describen 3 casos pediátricos con diagnóstico de infección por virus de la inmunodeficiencia humana y patología pulmonar crónica que presentaron síndrome de Cushing exógeno con fluticasona inhalada en dosis habituales por la interacción medicamentosa entre esta y ritonavir. Los pacientes resolvieron el cuadro clínico luego de 2-4 meses de suspensión de la fluticasona y permanecieron asintomáticos en el seguimiento

The increase in life expectancy with the advent of highly effective antiretroviral therapy poses challenges in terms of toxicity and drug interactions. Exogenous Cushing syndrome by interaction between ritonavir and inhaled fluticasone in children diagnosed with human immunodeficiency virus infection and chronic pulmonary pathology is rare. So far, there are 20 cases reported. Three pediatric cases are reported, with a diagnosis of human immunodeficiency virus infection and chronic pulmonary pathology who presented exogenous Cushing syndrome with inhaled fluticasone at usual doses due to drug interaction between it and ritonavir. The patients resolved the clinical Síndrome de Cushing exógeno por interacción medicamentosa de ritonavir y fluticasona inhalada. Reporte de tres casos pediátricos Exogenous Cushing syndrome due to drug interaction of ritonavir and inhaled fluticasone. Report of three pediatric cases picture after 2-4 months of fluticasone suspension and remain asymptomatic in the follow-up.

Adrenal masses are mainly detected unexpectedly by an imaging study performed for reasons unrelated to any suspect of adrenal diseases. Such masses are commonly defined as “adrenal incidentalomas” and represent a public health challenge because they are increasingly recognized in current medical practice. Management of adrenal incidentalomas is currently matter of debate. Although there is consensus on the need of a multidisciplinary expert team evaluation and surgical approach in patients with significant hormonal excess and/or radiological findings suspicious of malignancy demonstrated at the diagnosis or during follow-up, the inconsistency between official guidelines and the consequent diffuse uncertainty on management of small adrenal incidentalomas still represents a considerable problem in terms of clinical choices in real practice. The aim of the present work is to review the proposed strategies on how to manage patients with adrenal incidentalomas that are not candidates to immediate surgery. The recent European Society of Endocrinology/European Network for the Study of Adrenal Tumors guidelines have supported the view to avoid surveillance in patients with clear benign adrenal lesions <4 cm and/or without any hormonal secretion; however, newer prospective studies are needed to confirm safety of this strategy, in particular in younger patients.

Esthesioneuroblastoma as a source of ectopic Cushing's syndrome is rare, and to the best of our knowledge, only 20 cases have been reported worldwide. A 46-year-old healthy man visited a local clinic for general weakness and hyposmia, and underwent examination with serial endocrinological workup and brain imaging. ⁶⁸Gallium-DOTA-TOC positron emission tomography scan was helpful where diagnosis of sellar MRI and inferior petrosal sinus sampling were discordant. Combined transcranial and endoscopic endonasal approach surgery was performed, and a diagnosis of esthesioneuroblastoma was given.
