ResumenIntroducción. Las conductas agresivas y discriminatorias afectan la salud física y mental incluso de quienes las cometen. Los estudiantes están sometidos a situaciones de estrés, las cuales aumentan el riesgo de desarrollar dichas conductas y a sufrir sus consecuencias. Por otro lado, la Escuela de Medicina tiene como propósito formar integralmente profesionales médicos, con capacidad de evitar situaciones de violencia y convivir pacíficamente. Es por ello el interés de describir este problema en la Escuela de Medicina de la Universidad Nacional Mayor de San Marcos, Lima, Perú. Objetivo. Abordar la situación de violencia (bullying) en estudiantes de Medicina Humana del 6° año que no habían participado en el Programa de Formación Integral en la UNMSM. Diseño. Estudio descriptivo-transversal. Lugar. Sede docente "Instituto Nacional de Salud del Niño", Lima, Perú. Participantes. Muestra conformada por 93 (63%) estudiantes matriculados en el sexto año de la Facultad de Medicina que llevaron el curso de Pediatría durante los meses de julio a noviembre de 2015. Intervenciones. Se utilizó un instrumento desarrollado y validado por la Defensoría del Pueblo de España, modificado y corregido por Hoyos y col. Se calcularon las frecuencias y porcentajes de las respuestas. Resultados. Las conductas de violencia fueron más prevalentes entre estudiantes, entre ellas la conducta de agresión verbal más practicada fue la de expresarse de mala manera (40,8%). Conclusiones. La existencia de violencia se presenta en un alto porcentaje de la población estudiada y están implicados en ella docentes y estudiantes. Palabras clave. Violencia; Bullying; Estudiantes; Docentes. Abstract Introduction. Aggressive and discriminatory behavior affects physical and mental health even on those who commit them. Students are subjected to stress, which increases the risk of those behaviors and makes them likely to suffer from its consequences. On the other hand, the Medical School aims to educate medical professionals integrally, with abilities to avoid violence and live peacefully. That is why the interest of describing this problem in Universidad Nacional Mayor de San Marcos, Lima, Peru's Medical School. Objective. To address violence in students from the sixth year of Human Medicine who had not participated in the Integral Formation Program in UNMSM. Design: Descriptive, transversal study. Setting.

Summary The first case of the novel coronavirus infection (COVID-19) in Peru was reported on March 6, 2020. As of September 7, 2020, about 700 000 cases of COVID-19 resulting in 29,976 deaths have been confirmed by the Ministry of Health. Among COVID-19 patients with co-morbidities, type 2 diabetes mellitus (T2DM) has been recognized as a risk factor for severe disease. Patients with T2DM may experience diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic (HHS) if infected with the coronavirus 2 (SARS-CoV-2). Regular blood analysis including arterial blood gas is essential in monitoring the care of patients with T2DM infected with COVID-19. We report five cases of DKA in patients with underlying T2DM that presented with severe COVID-19 infection. Learning points COVID-19 may cause acute metabolic dysregulations in patients with T2DM. It is important to monitor basic metabolic panel (BMP) and arterial blood gases (ABGs) in patients with COVID-19 since metabolic complications can develop unexpectedly. Patients with T2DM develop an inflammatory syndrome characterized by severe insulin resistance and B cell dysfunction that can lead to DKA.

Adrenal hemorrhage is the most common cause of adrenal mass in newborns. We present a case of a fullterm male, born by cesarean section due to acute fetal distress from a mother with severe coronavirus disease 2019 (COVID-19) infection. He was diagnosed with hypoxic-ischemic encephalopathy, multifactorial shock, and early neonatal sepsis. On the seventh day of hospitalization, hemoglobin dropped and thus blood transfusion was required, and abdominal ultrasound showed bilateral adrenal hemorrhage. He developed relative adrenal insufficiency without either hemodynamic instability or electrolyte imbalances. The use of parenteral corticosteroids was not required. Follow-up ultrasonography and adrenal axis laboratory examination revealed complete resolution of adrenal hemorrhage. Neonatal adrenal hemorrhage has a wide variety of clinical manifestations. Ultrasound is preferred for both initial screening and follow-up evaluation. Adrenal insufficiency occurs rarely in neonatal adrenal hemorrhage. Treatment is usually conservative. We emphasize the importance of a timely diagnosis and clinical follow-up of adrenal hemorrhage in neonates with fetal distress born from mothers with severe COVID-19.

Introduction: Data has emerged about patients with T2DM may experience DKA and HHS if infected with SARS-CoV-2. There is limited data about new-onset diabetes in patients with COVID-19. We describe a case series of three Peruvian patients with new onset diabetes presenting with DKA who remained insulin dependent several months after infection resolution. Case 1: A 59-year-old man with no significant past medical history and normal glucose presented with fever and dyspnea for five days. He was hospitalized with hypoxemic respiratory failure and tested positive forCOVID19. Hypoxemia improved with supportive care, but on day three, he became lethargic, tachycardic, and tachypneic with 95% oxygen saturation on room air. Biochemistry revealed an anion gap metabolic acidosis with pH 7.3, bicarbonate 10 mmol/L (22–28), β-hydroxybutyrate 5.4 mmol/L (<0.5), and glucose 679 mg/dL. He was treated with continuous insulin infusion. After DKA resolved, he was transitioned to basal-bolus insulin and remained insulin-dependent during outpatient follow-up. Case 2: A 49-year-old man in good health prior to admission, was transferred to our hospital for acute respiratory failure and positive testing for SARS-CoV-2. Two days later he became confused, tachycardic, and tachypneic with 90% oxygen saturation. DKA was diagnosed based on a pH 7.1, bicarbonate 8 mmol/L, β-hydroxybutyrate 5 mmol/L and glucose 625 mg/dL. He was transferred to the ICU for continuous insulin infusion. After resolution of his DKA, subcutaneous insulin was started. Preadmission hemoglobin A1c was 4.5%. He remained on insulin post hospital discharge. Case 3: A 33-year-old man with normal glucose prior to admission was transferred to our hospital from an outpatient office with a two-day history of dyspnea and altered sensorium. He was tachycardic and tachypneic with 96% oxygen saturation on 3L nasal cannula. He tested positive for SARS-CoV-2. DKA was diagnosed with glucose 690 mg/dL, bicarbonate 4 mmol/L, serum β-hydroxybutyrate 5.8 mmol/L and pH 6.6. He was resuscitated with intravenous fluids and an insulin infusion was started. DKA resolved after 5 days and he was discharged home on subcutaneous insulin. He remained insulin-dependent on follow-up. Conclusion: New-onset diabetes with DKA due to SARS-CoV-2 is increasingly recognized, and beta-cell dysfunction can be permanent, resulting in insulin-dependent diabetes. Accordingly, our patients remained insulin-dependent several months post discharge.

Elemental mercury ingestion caused by folk practices is rare and usually harmless. Nevertheless, some complications related to mercury ingestion have been reported such as appendicitis related to mercury sequestration and poisoning leading to systemic toxicity. Patients usually present with nausea, vomiting, and abdominal tenderness. Mercury sequestration in the appendix depends on its anatomy and mercury physical properties, both of which may lead to appendicitis, resulting in subsequent peritonitis leading to multiple and severe surgical complications. A 26-year-old Peruvian man complaining of vomiting and abdominal pain after ingestion of elemental mercury as part of a folk practice presented to the emergency department. Physical exam was remarkable for rigid abdomen and diffuse rebound sign. A clinical diagnosis of peritonitis was made. The patient was taken to the operating room where an open appendectomy and peritoneal lavage were performed. On gross inspection, a silver foreign body within the perforated appendix was seen by the surgical team. The patient developed multiple surgical complications leading to multiple organ failure and death. Clinicians should be aware that mercury ingestion is usually benign. However, severe complications may develop. Early surgical and medical intervention should be initiated promptly to achieve better outcomes. We present the first case of peritonitis due to appendicitis related to mercury sequestration in the appendix.

This review provides an update on the epidemiology, pathophysiology, symptoms, diagnosis and treatment of neuroendocrine neoplasms (NENs) of the small bowel (SB). These NENs are defined as a group of neoplasms deriving from neuroendocrine cells. NENs are currently the most common primary tumors of the SB, mainly involving the ileum, making the SB the most frequently affected part of the gastrointestinal tract. SB NENs by definition are located between the ligament of Treitz and the ileocecal valve. They are characterized by small size and induce an extensive fibrotic reaction in the small intestine including the mesentery, resulting in narrowing or twisting of the intestine. Clinical manifestations of bowel functionality are related to the precise location of the primary tumor. The majority of them are non-functional NENs and generally asymptomatic; in an advanced stage, NENs present symptoms of mass effect by non-specific abdominal pain or carcinoid syndrome which appears in patients with liver metastasis (around 10%). The main manifestations of the carcinoid syndrome are facial flushing (94%), diarrhea (78%), abdominal cramps (50%), heart valve disease (50%), telangiectasia (25%), wheezing (15%) and edema (19%). Diagnosis is made by imaging or biochemical tests, and the order of request will depend on the initial diagnostic hypothesis, while confirmation will always be histological. All patients with a localized SB NEN with or without near metastasis in the mesentery are recommended for curative resection. Locoregional and distant spread may be susceptible to several therapeutic strategies, such as chemotherapy, somatostatin analogs and palliative resection.

La acromegalia es una enfermedad rara, causada principalmente por un tumor hipofisiario secretor de hormona de crecimiento (GH), se caracteriza por tener progresión lenta y asociarse a un compromiso multisistémico, siendo el aparato cardiovascular uno de los más comprometidos, llegando, incluso, desde hace más de 10 años a representar la principal causa de muerte. Las complicaciones cardiovasculares se desarrollan como resultado de las concentraciones sanguíneas elevadas de la GH y del factor de crecimiento similar a la insulina tipo 1 (IGF-1), los cuales ejercen efectos directos e indirectos sobre el endotelio, grandes vasos, riñón y los cardiomiocitos; produciendo hipertensión arterial, enfermedad valvular, arritmia cardiaca y una cardiopatía propia de la acromegalia denominada miocardiopatía acromegálica. Luego de la revisión bibliográfica actualizada relacionada con la fisiopatología, manifestaciones clínicas, diagnóstico y tratamiento del compromiso cardiovascular, encontramos que desde el punto de vista cardiovascular los pacientes con acromegalia pueden variar desde un estado asintomático hasta presentar disfunción cardiaca severa, siendo los marcadores bioquímicos y exámenes de imagen herramientas diagnósticas que permiten evaluar el grado de afección cardiovascular para poder brindar un tratamiento individualizado. La normalización de los valores de la GH y del IGF-1 mejora los parámetros cardiovasculares y, por tanto, su pronóstico.
