[Acute pancreatitis due to hepatitis B virus. A case report]. / Pancreatitis aguda por virus de la hepatitis B. Reporte de un caso.

Acute pancreatitis is an inflammatory condition that is related to various etiologies. However, an infrequent one is acute infection by hepatotropic viruses. We present the case of a 33-year-old man who consulted the emergency department for abdominal pain and generalized jaundice. Serological studies reported acute infection by Hepatitis B Virus; The patient was managed with clinical and paraclinical monitoring of liver function tests together with supportive therapy with dextrose. The patient persisted with increasing abdominal pain and cholestasis, so they were considered differential. Magnetic resonance imaging of the upper abdomen showed acute non-biliary pancreatitis that was concluded secondary to the infectious process due to hepatitis B after ruling out other causes. The patient did not require changes in management with improvement in liver function tests, so he was discharged from hospital with favorable evolution in outpatient follow-up. Acute pancreatitis secondary to Hepatitis B Virus is a pathology that should be suspected and studied when the patient's clinical picture does not show improvement; Diagnosis is based on measurement of pancreatic enzyme levels.

Síndrome nefrótico por enfermedad de cambios mínimos asociado a enfermedad de Graves y uso de metimazol

Introduction: Graves' disease causes kidney injury through a series of multiple mechanisms, including the treatment for this condition. Nephrotic syndrome due to minimal change disease (MCD) is an unusual form of such kidney injury; the association between methimazole use and MCD is also rare. Case presentation: A 36-year-old woman with a history of Graves' disease in use of methimazole for several months, who presents edematous syndrome due to nephrotic syndrome associated with a KDIGO stage 3 acute kidney injury. Thionamide-induced hypothyroidism and the need of thyroid hormone replacement therapy was evidenced at the time of consultation. Based on a renal biopsy, the patient was diagnosed with MCD, her condition worsened as she experienced oliguria and hypervolemia, therefore, renal replacement therapy with hemodialysis was temporarily required. Methimazole administration was suspended, and treatment consisting of prednisolone administration and levothyroxine supplementation was started, achieving hemodialysis suspension, gradual improvement of proteinuria until remission and a full-maintained recovery of renal clearance. Radioiodine therapy was implemented as definitive treatment for Graves' disease, obtaining a successful outcome. Conclusions: Graves' disease and methimazole use are possible causes of minimal change disease; systemic corticosteroid therapy is a possible management. However, further basic, clinical and epidemiological research on this subject is required.

Introducción: La enfermedad de Graves genera daño renal por múltiples mecanismos, incluyendo sus tratamientos. El síndrome nefrótico por enfermedad de cambios mínimos, es una forma inusual de dicho daño renal en la enfermedad de Graves; la asociación de esta condición renal con el metimazol también es anómalo. Presentación del caso: Una mujer de 36 años con antecedente de enfermedad de Graves en uso de metimazol hacía meses, quien debutó con síndrome edematoso por síndrome nefrótico asociado a una lesión renal aguda KDIGO etapa 3. Se evidenció hipotiroidismo inducido por la tionamida con necesidad de suplencia al momento de la consulta. Asimismo, se realizó biopsia renal que concluyó en enfermedad de cambios mínimos. La paciente progresó a oliguria con hipervolemia sin respuesta a diurético del asa por lo que requirió terapia de reemplazo renal con hemodiálisis de forma transitoria. Se retiró el metimazol, se dio manejo con prednisolona y con suplencia tiroidea, lográndose el retiro de la hemodiálisis con mejoría gradual de la proteinuria hasta la remisión y recuperación de la depuración renal de forma plena y mantenida. Se dio manejo definitivo a la enfermedad de Graves con yodo radioactivo con éxito terapéutico. Discusión y conclusiones: La enfermedad de Graves y el metimazol son causas posibles de enfermedad de cambios mínimos; el tratamiento con corticoide sistémico se postula como una posible estrategia de manejo. Se requiere más investigación básica, clínica y epidemiológica en el tema.

Pancreatitis aguda por virus de la hepatitis B. Reporte de un caso

La pancreatitis aguda es una condición inflamatoria que está relacionada con diversas etiologías. Sin embargo, una infrecuente es la infección aguda por virus hepatotropos. Se presenta el caso de un hombre de 33 años quien consultó al servicio de urgencias por dolor abdominal e ictericia generalizada. Los estudios serológicos reportaron infección aguda por Virus de la Hepatitis B; el paciente fue manejado con vigilancia clínica y paraclínica de pruebas de función hepática junto con terapia de soporte con dextrosa. El paciente persistió con dolor abdominal y colestasis en aumento por lo que se consideraron diferenciales. La imagen por resonancia magnética de hemiabdomen superior demostró pancreatitis aguda no biliar que se concluyó secundaria al proceso infeccioso por hepatitis B al descartar otras causas. El paciente no requirió cambios en el manejo con mejoría en pruebas de función hepática por lo que se dio egreso hospitalario con evolución favorable en el seguimiento ambulatorio. La pancreatitis aguda secundaria al Virus de la Hepatitis B es una patología que se debe sospechar y estudiar cuando el cuadro clínico del paciente no demuestra mejoría; el diagnóstico se fundamenta en la medición de los niveles de las enzimas pancreáticas.

Pyomyositis and fasciitis by carbapenem resistant microorganism in a patient with severe tophaceus gout / Piomiositis y fascitis asociadas a microorganismo resistente a carbapenémicos, en un paciente con gota tofácea severa

Abstract Pyomyositis, defined as a suppurative muscle infection, is a rare entity that is classified as tropical or non-tropical according to the geographical region. The case of a patient with a history of severe tophaceous gouty arthritis, coming from tropical wet climate in Colombia, who presented with suggestive cellulitis, with a torpid evolution despite standard dual management. An associated abscess was documented, and initially abscessed cellulitis and septic arthritis were suspected, the latter was finally ruled out, once teh muscle origin of the abscess becames evident by means of computed tomography and ultrasonography. Intraoperatively, an abscess with fascia involvement and intramuscular tophaceous disease was observed. Surgical drainage and repeated washes were required. Carbapenem resistant Klebsiella pneumoniae was isolated, requiring last-line Gouty arthritis antibiotic therapy for a prolonged period of time.

Resumen La piomiositis es una infección supurativa del músculo estriado, rara, que se clasifica según la región geográfica de presentación, en tropical y no tropical. Se presenta el caso de un paciente con antecedente de artritis gotosa tofácea severa, proveniente de zona tropical, quien comienza con cuadro sugestivo de celulitis, con evolución tórpida pese a manejo estándar dual; se documenta un absceso de ubicación no clara, sospechando en principio celulitis abscedada y artritis séptica, finalmente descartándose esta última y haciéndose evidente origen muscular del absceso por medio de tomografia computarizada y ultrasonografía. Quirúrgicamente se evidenció absceso con compromiso de fascia, enfermedad tofácea intramuscular; requirió drenaje quirúrgico y lavados, documentándose germen Klebsiella pneumoniae resistente a carbapenémicos, requiriendo antibioticoterapia de última línea por un periodo prolongado.

Spontaneous pneumomediastinum. case report

ABSTRACT Introduction: Spontaneous pneumomediastinum (SPM) is defined as the presence of air in the mediastinum. It is a rare entity considered benign and self-limiting, which mostly affects young adults. Its diagnosis is confirmed through clinical and radiological studies. Case description: 21-year-old male patient with cough and greenish expectoration for four days, associated with dyspnea, chest pain, fever and bilateral supraclavicular subcutaneous emphysema. Chest X-ray suggested pneumomediastinum, which was confirmed by tomography. The patient was hospitalized for observation and treatment. After a positive evolution, he was discharged on the sixth day. Discussion: SPM is a differential diagnosis in patients with chest pain and dyspnea. Its prevalence is lower than 0.01% and its mortality rate is low. It should be suspected in patients with chest pain and subcutaneous emphysema on physical examination. Between 70 and 90% of the cases can be identified by chest X-ray, while confirmation can be obtained through chest tomography. In most cases it does not require additional studies. Conclusion: SPM is a little known cause of acute chest pain, and rarely considered as a differential diagnosis; it is self-limited and has a good prognosis.

Infected pulmonary infarction case report / Infarto pulmonar infectado. reporte de caso

ABSTRACT Introduction: Pulmonary infarction occurs in 29% to 32% of patients with pulmonary thromboembolism (PTE). The infection of a pulmonary infarction is a complication in approximately 2 to 7% of the cases, which makes it a rare entity. Case Presentation: 49-year-old woman with pleuritic pain in the left hemithorax that irradiated to the dorsal region, associated with dyspnea and painful edema in the left lower limb of two days of evolution. Two weeks prior to admission, the patient suffered from a left knee trauma that required surgical intervention; however, due to unknown reasons, she did not receive antithrombotic prophylaxis. Physical examination showed tachycardia, tachypnea and painful edema with erythema in the left leg. After suspecting a pulmonary thromboembolism, anticoagulation medication was administered and a chest angiotomography was requested to confirm the diagnosis. The patient experienced signs of systemic inflammatory response, and respiratory deterioration. A control tomography was performed, suggesting infected pulmonary infarction. Antibiotic treatment was initiated, obtaining progressive improvement; the patient was subsequently discharged, and continued with anticoagulation medication and follow-up on an outpatient basis. Conclusions: Pulmonary infarction is a frequent complication in patients with PTE. Therefore, infected pulmonary infarction should be suspected in patients with clinical deterioration and systemic inflammatory response. The radiological difference between pulmonary infarction and pneumonia is not easily identified, thus the diagnostic approach is clinical, and anticoagulant and antimicrobial treatment should be initiated in a timely manner.

RESUMEN Introducción El infarto pulmonar ocurre entre un 29 y un 32% de pacientes con tromboembolismo pulmonar (TEP). Por su parte, la infección de un infarto pulmonar complica aproximadamente del 2 al 7% de los casos, lo que hace que el infarto pulmonar infectado sea una entidad poco frecuente. Descripción del caso Mujer de 49 años con dolor pleurítico en hemitórax izquierdo, irradiado a región dorsal, asociado a disnea y edema doloroso de miembro inferior izquierdo de dos días de evolución. Dos semanas antes de su ingreso la paciente sufrió trauma de rodilla izquierda, el cual que requirió intervención quirúrgica; sin embargo, por motivos desconocidos, no recibió profilaxis anti trombótica. En el examen físico se encontró taquicardia, taquipnea y edema doloroso con eritema en pierna izquierda. Al existir alta sospecha de tromboembolia pulmonar se inició anticoagulación y se solicitó angiotomografía de tórax, con la cual fue posible confirmar el diagnóstico. Durante su evolución, la paciente experimentó signos de respuesta inflamatoria sistémica, deterioro respiratorio. Se realizó tomografía de control sugestiva de infarto pulmonar infectado. Se inició antibiótico y la paciente mejoró de forma progresiva; después de esta mejora, fue dada de alta para continuar anticoagulación y seguimiento ambulatorios. Conclusiones El infarto pulmonar es una complicación frecuente en pacientes con TEP. Por lo tanto, debe sospecharse infarto pulmonar infectado en pacientes con deterioro clínico y respuesta inflamatoria sistémica. La diferencia radiológica entre infarto pulmonar y neumonía no es fácil de identificar, su enfoque diagnóstico es clínico y el tratamiento anticoagulante y antimicrobiano debe iniciarse de manera oportuna.

Case report: why, what for and how / El reporte de caso: por qué, para qué y cómo hacerlo

THE IMPORTANCE OF CASE REPORTS This search for truth mechanisms in Medicine is especially applicable when its object of study is the biological machine that makes up humans. This conception of Medicine ­which could be called positivist­ is limited and impractical if applied in isolation, although there are strong attempts to clearly define its object of study from reductionism because of the complexity of humans as a biological phenomenon and as a social, ethical and political entity.

Piomiositis del músculo esternocleidomastoideo. Reporte de un caso en Colombia y revisión de la literatura / A literature review and case report concerning pyomyositis of the sternocleidomastoid muscle in Colombia

La piomiositis es la infección del músculo estriado. Siendo en conjunto infrecuente, lo es aún menos en los músculos del cuello. Se presenta el caso clínico de un hombre ecuatoriano de 19 años residente en Colombia, en quien se diagnosticó piomiositis del esternocleidomastoideo derecho en estadio dos, con escaso compromiso sistémico. Se documentó ecográfica y tomográficamente absceso asociado. Fue tratado conservadoramente con antibioticoterapia -clindamicina y gentamicina- sin necesidad de drenaje del absceso con adecuada evolución y resolución del cuadro. Se realiza una revisión general de la piomiositis y se revisan los casos publicados en Colombia y en el mundo, específicamente del cuello y del músculo esternocleidomastoideo; se encontró que dicho músculo es el más afectado en el cuello. El primer caso colombiano fue publicado en 1990 y se identificó el Staphylococcus aureus como el patógeno más frecuente, aunque también están implicados otros cocos grampositivos y enterobacterias.

Pyomyositis is an infection of the skeletal muscle, occurring infrequently and to a lesser extent in the neck muscles. This paper presents the case of a 19-year-old Ecuadorian male living in Colombia; he was diagnosed with pyomyositis stage 2 in the right sternocleidomastoid muscle, with little systemic involvement. An echography and computer tomography documented an abscess. He was treated conservatively with just antibiotics (clindamycin and gentamicin), without abscess drainage, leading to good progress and resolution of the illness. This paper presents a general review of pyomyositis, cases reported to date in Colombia and the world, specifically regarding the neck and sternocleidomastoid muscle. The sternocleidomastoid muscle is most frequently involved in the neck; the first report of a case in Colombia was published in 1990 and Staphylococcus aureus has been the most frequent pathogen, although other Gram-Positive Cocci and Enterobacteriaceae have also been involved.
