Giant Cell Arteritis (GCA), formerly known as Horton Disease associated to the hyperthyroidism has been rarely reported. In this paper, we aimed to discuss a case that illustrating such association. The case consisted of 70-year-old woman who complained a sudden diffuse vision loss in the left eye since a week. Laboratory test showed hyperthyroidism. The cerebral CT-scan without contrast media revealed left ischemic stroke complicated by left choroidopathy. GCA and hyperthyroidism are considered independent and their coexistence was attributed to independent processes related to ischemic stroke.

The incidence of cancer has dramatically increased around the world. Among the different types, glioma (brain cancer) represents the majority of diagnosed brain tumors and is known to be a rapidly developing tumor with a high mortality rate. Therapies with viscum album have performed well in cancer treatments and have been the subject of many studies. This work evaluated the in vitro action of homeopathic medicines prepared with viscum album against glioma cells (KNS-42) and was possible to prove the cytotoxic activity of viscum album at D3, D6, D9, D12, and D30 potencies. This result broadens opportunities for homeopathy in cancer treatment as the primary therapy or as a complementary treatment.

Necrotizing enterocolitis (NE) is a common disease with a high associated mortality. NE is more common in preterm and low-birth-weight newborns, as well as patients with anemia, heart disease such as patent ductus arteriosus, sepsis or hypoxia at birth and patients receiving formula, among other causes.The pathophysiology of this disease is the premature exposure of the intestinal immune system to the intestinal flora. This premature exposure causes inflammation, mucosa disruption, vasoconstriction, and necrosis. This increases the risk of infectious pathogens that further damage the intestinal barrier and alter the bacterial flora. (2), perpetuating the local lesion (8), increasing morbidity and mortality. One third of these patients will eventually require surgery. Currently, there is no conclusive data on the risk of necrotizing enterocolitis at different altitudes in Latin America. Clarifying the effect of altitude in this disease will be essential in the management and prognosis of neonates affected by this illness(1).

Ectopic pregnancy is a condition in which the gestational sac is outside the uterine cavity, and is the most lifethreatening emergency condition in early pregnancy.
