RESUMEN

BACKGROUND Tetanus is a potentially fatal infectious disease which, during its evolution, creates multiple complications, usually requiring intensive management and care. CASE REPORT We present a clinical case of a 59-year-old male patient with generalized tetanus admitted to the intensive care unit. Flexible bronchoscopy revealed contraction of the bronchial demonstrating that tetany existed at the respiratory level, which rarely becomes evident. The clinical manifestations included trismus, facial paralysis, neck stiffness, and compromised respiratory function. The patient presented a state of respiratory failure that required invasive mechanical ventilation which was evaluated by bronchoscopy and that showed spasms of the bronchial musculature. The patient presented generalized tetanus in which the bronchial affectation was evaluated by bronchoscopy in the intensive care unit. In developed countries, the anti-tetanus toxoid vaccine has ostensibly decreased its incidence, while it is endemic in developing countries, and although there are measures such as vaccination that try to reduce its incidence, in Ecuador there is an increase in incidences. In this patient case, contraction of the bronchial rings was observed, demonstrating that tetany existed at the respiratory level, which rarely becomes evident. CONCLUSIONS Although muscular contractions are widespread, this clinical case evidences bronchial spams reported and visualized by bronchoscopy.

RESUMEN

Introduction: celiac disease is an autoimmune disease with symptoms involving multiple organs. The forms of presentation vary considerably, which makes it difficult to diagnose. The objective is to present an atypical case of celiac disease. Methodology: descriptive, retrospective, cross-sectional study of a case of an adult woman who presented with tetany Results: investigating the case, the diagnosis of tetany was reached secondary to an intestinal malabsorption Conclusion: celiac disease can occur atypically as a tetany

Introducción: Introducción: la enfermedad celiaca es una enfermedad autoinmune con síntomas que involucran a múltiples órganos. Las formas de presentación varían de modo notable lo que dificulta su diagnóstico. El objetivo es presentar un caso atípico de enfermedad celiaca. Metodología: estudio descriptivo, retrospectivo, de corte transversal de un caso de mujer adulta que se presentó con tetania Resultados: investigando el caso se llegó al diagnóstico de tetania secundaria a un síndrome de malabsorción intestinal debida a enfermedad celiaca, confirmada por histología. Conclusión: la enfermedad celiaca puede presentarse atípicamente como una tetania.

RESUMEN

Phosphate enemas are frequently used in the treatment of constipation. Errors in dosage and administration can lead to severe complications. OBJECTIVE: To report a case of severe toxicity of phosphate enemas in a child with no risk factors. CASE: 2 years old female, with functional constipation, was brought to emergency department because abdominal pain. She was diagnosed with fecal impaction and received half a bottle of Fleet Adult® (Laboratorio Synthon, Chile) two times, with no clinical resolution, deciding to start proctoclisis in pediatric ward. Soon after admission, she presented painful tetany, but alert and oriented. Patient was transferred to PICU where severe hyperphosphatemia and secondary hypocalcemia were confirmed. Her treatment included electrolyte correction; removal of residual phosphate enema and hyperhydration. Tetany resolved over 2 hours after admission and no other complications. Proctoclisis was performed and patient was discharged three days after admission with pharmacological management of constipation. CONCLUSION: Phosphate enemas may cause serious complications in children with no risk factors. Errors in dosage, administration and removal of the enema are causes of toxicity in this group. Pediatricians and health personnel must be aware of risks and signs of toxicity of phosphate enema.

RESUMEN

Los enemas fosfatados son utilizados frecuentemente en el tratamiento de la constipación. Errores en la posología pueden producir complicaciones graves. Objetivo: Reportar un caso de toxicidad grave por enema fosfatado en un pre escolar sin factores de riesgo. Caso clínico: Paciente de 2 años con constipación funcional, evaluada en servicio de urgencia por dolor abdominal a quién se le diagnosticó un fecaloma impactado. Recibió 2 dosis de enema de fosfato, “medio frasco” de Fleet® adulto (Synthon, Chile) por vez, sin resolución de su fecaloma, decidiéndose hospitalización para proctoclisis. Posterior al ingreso presentó un cuadro clínico de tetania. Ingresó a la Unidad de Paciente Crítico donde se confirmó una hiperfosfemia e hipocalcemia secundaria. Se realizó corrección electrolítica progresiva, retiro de enema fosfatado residual del recto e hiperhidratación forzando diuresis. La tetania cedió 2 horas después del ingreso sin otras complicaciones. Se realizó proctoclisis y fue dada de alta a los 3 días. Conclusión: Los enemas fosfatados pueden presentar complicaciones graves en niños sin factores de riesgo. Errores en la posología son la causa más frecuente de toxicidad en este grupo, pero esta puede estar favorecida también por una administración y eliminación inadecuadas. Pediatras y personal de salud que atiende a niños deben conocer factores de riesgo, signos y síntomas de intoxicación por enemas fosfatados.

RESUMEN

Acute renal failure secondary to interstitial nephritis caused by therapeutic ingestion of sodium diphenylhydantoins has been reported recently. The interference of sodium diphenylhydantoins on Vitamin D metabolism causing or aggravating ricketts has also been reported. This communication deals with an infant girl who was admitted to the hospital due to seizures. Four months before, she had convulsions and she was treated with diphenylhydantoins until admission. She was found to have renal failure and ricketts. Histological diagnosis of interstitial nephritis was established by means of percutaneous renal biopsy. Clinical and radiological improvement of ricketts was observed after dehydrotachysterol treatment. Clinical and biochemical alterations of renal failure slowly subsided. She had a clear-cut history of vitamin D defficiency ricketts. Seizures were due to hypocalcemia tetany but was erroneusly treated as "grand mal" epilepsy, with diphenylhydantoins. Interstitial nephritis complicated with acute renal failure was probably caused by diphenylhydantoins administration.
