Abstract Background Prader–Willi syndrome is a complex multisystem disorder due to the absent expression of paternally active genes in the Prader–Willi syndrome-critical region on chromosome 15 (15q11.2-q13). The main clinical features are hyperphagia (which frequently results in early-onset obesity), hypogonadism, developmental delays, typical behaviors (such as obsessive–compulsive tendencies, tantrums, perseveration, insistence on sameness, and rigidity), and distinctive facial features. In infants, the most prominent findings are hypotonia and feeding difficulties. Case presentation This paper highlights a case of a 14 year old male patient of an Ethiopian ethnicity with diagnosis of Prader–Willi syndrome, which is first report in Ethiopia. He presented with progressive excessive weight gain, insatiable appetite, clinical and laboratory features of hypogonadism, ophthalmological refractory error, and facial features of Prader–Willi syndrome, which was further confirmed by genetic analysis. He is currently on lifestyle intervention, testosterone replacement, and treatment for vitamin D deficiency. Conclusion Prader–Willi syndrome should be considered in a child who presents with progressive weight gain and other typical clinical features such as cognitive impairment, excessive insatiable eating, or hypothalamic hypogonadism. Early lifestyle intervention may help to reduce excessive weight gain. To our knowledge, this is the first case reported in Ethiopia.

Abstract Background Recurrent episodes of hypoglycemia may be caused by several factors, including drugs, critical illnesses, hormonal deficiency, non-islet cell tumor endogenous hyperinsulinism, and accidental, surreptitious, or malicious hypoglycemia. Multiple drugs have been previously reported as causes of hypoglycemia, with moderate and low-quality evidence. However, Clopidogrel as a cause of non-diabetic hypoglycemia is rarely reported. Here we describe a single non-diabetic patient who experienced recurrent episodes of hypoglycemia after initiation of clopidogrel for clinical suspicion of acute coronary syndrome. Case presentation The patient, a 33-year-old Ethiopian male with documented hypertension on antihypertensive medication, has started receiving treatment for acute coronary syndrome after experiencing angina symptoms. He experienced hypoglycemia following the start of Clopidogrel, but it subsided once it was stopped. Currently, he has a follow-up at the cardiac clinic with a normal measurement of his serum blood glucose level. Conclusion Non-diabetic hypoglycemia is a rare illness characterized by low blood glucose levels in people who do not have diabetes. Patients with severe hypoglycemia may become unconscious or have seizures as a result of low blood sugar. Severe hypoglycemia is fatal and must be treated as soon as possible. Therefore, if non-diabetic hypoglycemia occurs, a thorough evaluation of the causes is essential, particularly any potential drug as a cause of hypoglycemia should be evaluated.
