RESUMEN
INTRODUCTION: Awareness regarding the etiological spectrum of tetany is poor among physicians. Because of poor awareness, tetany is underdiagnosed and undertreated. MATERIALS AND METHODS: Databases like PubMed, PubMed Central, Scopus, and Google Scholar are searched to identify peer-reviewed articles on tetany. Case reports, case series, and original articles are analyzed to identify different causes of tetany prevalent in the community. Different causes found are analyzed and tabulated, and finally, a flowchart is made on the approach for diagnosing different underlying pathologies of tetany. RESULTS: Both metabolic and respiratory alkalosis are important causes of tetany because of reduced ionized calcium levels. Gitelman syndrome (GS) is associated with metabolic alkalosis, hypokalemia, hypomagnesemia and hypocalciuria, and frequently causes normocalcemic tetany. Recurrent vomiting and primary hyperaldosteronism also cause tetany due to metabolic alkalosis. Hyperventilation syndrome (HVS) leads to respiratory alkalosis and is a frequent cause of tetany. Hyperventilation-induced tetany is also seen after spinal anesthesia and in respiratory disorders like asthma. Vitamin D deficiency (VDD), primary hypoparathyroidism, and pseudohypoparathyroidism (PHP) (1a, 1b, and 2) cause hypocalcemic tetany. Hypomagnesemia causes hypocalcemia and tetany due to peripheral parathyroid hormone resistance and impaired parathyroid hormone secretion. Drugs causing tetany include bisphosphonates, denosumab, cisplatin, antiepileptics, aminoglycosides, diuretics, etc. Tetany is also seen in acute pancreatitis, dengue, falciparum malaria, hyperemesis gravidarum, tumor lysis syndrome (TLS), massive blood transfusion, etc. Conclusion: The spectrum of disorders associated with tetany is diverse. Awareness of different causes will help early and proper diagnosis of tetany.

Celiac disease is an immune-mediated systemic disease with a wide spectrum of clinical presentations. The term celiac crisis describes the acute and potentially fatal form. Clinically it is characterized by severe diarrhea, dehydration, and metabolic disturbances. The case of a 7-year-old male patient attending the ward with tetany, lower limb edema, steatorrhea and weight loss of 8 months of evolution is reported, with analytical findings of hypocalcemia, hypomagnesemia, hypokalemia and coagulopathy. The diagnosis of celiac crisis was made on the basis of serological and clinical findings compatible with celiac disease in the context of severe metabolic abnormalities and acute malnutrition, later confirmed by pathological anatomy. The importance of this report lies in reviewing the characteristics of this serious entity, which requires a high index of suspicion for its diagnosis.

Malaria is a common public health problem which may have high morbidity and mortality. Physicians should be aware of the unusual presentations of this disease so that it can be timely diagnosed and treated. Herein we are presenting a case of falciparum malaria who presented to the hospital with carpopedal spasm and tetany. We will subsequently discuss mineral homeostasis and the mechanisms of hypocalcaemia in falciparum malaria and the dysregulation of calcium, phosphorus and magnesium metabolism.

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.

Pseudohypoparathyroidism (PHP) is a rare group of disorders characterised by end-organ resistance to the parathyroid hormone (PTH). A 16-year-old boy presented with a 2-year history of involuntary dystonic movements involving mainly the left hand, initially after writing and later during physical exercise. Serum calcium was 1.37 mmol/L (2.20-2.69), phosphate 2.1 mmol/L (0.8-1.45) and PTH 302 ng/L (12-88). CT scan of the head demonstrated multiple subcortical and diffuse basal ganglia calcifications. Genetic analysis confirmed a methylation defect in the GNAS cluster on chromosome 20q13.32 which established the diagnosis. Treatment with calcitriol and calcium carbonate led to complete remission of symptoms. Causes of hypocalcaemia should be considered in evaluating patients with movement disorders. The diagnosis of PHP-1B is challenging but the overall prognosis is excellent.

RATIONALE: Camurati-Engelmann disease (i.e., progressive diaphyseal dysplasia) is an extremely rare autosomal dominant bone disorder. The most common clinical manifestations were chronic skeletal pain, waddling gait, muscular weakness. PATIENT CONCERNS: We described that a 27-year-old male with a 1-year history of intermittent tetany was referred for bone scintigraphy. The whole body bone scan images showed abnormal increased uptake of the tracer in the long bones of the upper and lower extremities as well as in the skull. DIAGNOSES: Combined the family history, the findings of the images and the genetic study, the diagnosis of Camurati-Engelmann disease was confirmed. INTERVENTIONS AND OUTCOMES: The patient responded well to the treatment of calcium gluconate. LESSONS: Bone scintigraphy would be helpful in the diagnosis and assessing the severity of Camurati-Engelmann disease.

Hyperventilation can be a manifestation of anxiety that involves abnormally fast breathing (tachypnea) and an elevated minute ventilation that exceeds metabolic demand. This report describes a case of hyperventilation-induced hypocapnia resulting in tetany in a 16-year-old girl undergoing orthodontic extractions under intravenous conscious sedation. Pulse oximetry is the gold standard respiratory-related index in conscious sedation. Although the parameter has great utility in determining oxygen desaturation, it provides no additional information on respiratory function, including, for example, respiratory rate. In this case, we found capnography to be a very useful aid to monitor respiration in this patient and also to treat the hypocapnia.

Tetany is a disorder with a very heterogeneous clinical manifestation. It includes neuromuscular hyperactivity, decreased attention, fatigue, constant anxiety. Attacks of tetany range from mild symptoms, which includes circumoral and distal paresthesias, hyperventilation, accompanied by shortness of breath, palpitation, dizziness, nausea and carpopedal spasm, through more severe symptoms like generalized seizures, loss of consciousness, muscle crumps to life-threatening emergencies like laryngospasm or arrhythmias. Tetany can be a result of many electrolyte disturbances, like hypocalcaemia, hypomagnesemia, hypokalaemia, alkalosis and electrolyte disturbances following hyperventilation. These disorders may occur in many clinical situations including diet deficiencies, alcoholism, endocrine diseases, genetic disorders, iatrogenic causes like proton pump inhibitors therapy and many, many others. It happens that tetany is diagnosed too late and therefore insufficiently cured. For these reason it deserves closer attention.

Although glucocorticoids have a known negative effect on calcium balance, they do not normally cause clinically significant hypocalcaemia. A young woman with post-surgical hypoparathyroidism developed symptomatic hypocalcaemia on two occasions following treatment with intravenous hydrocortisone for allergic reactions. Oral calcium and vitamin D supplementation could not prevent the development of hypocalcaemia. She was treated successfully with intravenous calcium gluconate infusions and discontinuation of glucocorticoids. In patients with hypoparathyroidism, impaired parathyroid hormone response to steroid-induced negative calcium balance may result in severe symptomatic hypocalcaemia requiring hospitalisation.
