Internal carotid artery (ICA) agenesis is a rare developmental anomaly and is most frequently asymptomatic, but it may also present as cerebrovascular accidents. The association with Horner's syndrome is exceptional. We present three cases of agenesis of ICA associated with Horner's syndrome and hypochromia iridum presenting as focal neurological symptoms. A system of collaterals develops as a ...

Tube thoracostomy is a common therapeutic approach applied in medical practice. Certain complications of this procedure have been described in the literature. Oculosympathetic paresis, or Horner's syndrome, occurs from the interruption of second order preganglionic neurons and manifests as miosis, ptosis, hemifacial anhidrosis and enophthalmos. Iatrogenic Horner's syndrome, on the other hand, v...

X-linked recessive anhidrotic ectodermal dysplasia with immunodeficiency is a developmental and immunologic disorder caused by mutations in nuclear factor-kappaB essential modulator (NEMO), which is essential for nuclear factor-kappaB activation. Early in life, affected boys present a typical appearance, with hypotrichosis or atrichosis, hypohidrosis or anhidrosis, and hypodontia or anodontia w...

Horner's syndrome is the triad of miosis, ptosis, and anhidrosis, resulting from disruption of the sympathetic pathways. This article describes an uncommon case of Horner's syndrome in a 22-year-old man after blunt trauma to the neck and chest without carotid artery dissection. The patient was brought to the emergency service after motorcycle fall. Neurologic examination revealed a patient pres...

ISSN 0001-5555 Bathing suit ichthyosis (BSI) is a rare variant of autosomal recessive lamellar ichthyosis (LI). In 2005, Jacyk first reported 13 cases of LI that presented with the characteristic distribution of lesions on the trunk but usually sparing the extremities and the central face (1). ...

A 60 year old male farmer presented with acute paraplegia, loss of sensations below the nipples and bowel-bladder incontinence since two days. On examination, Horner’s syndrome with ptosis, miosis and anhidrosis was noted on the left half of the face (Fig. 1). Small muscle wasting and ulnar clawing were noted in the left hand with diminished sensations suggesting a C8-T1 radiculopathy. There wa...

Nerve growth factor (NGF), a member of the neurotrophin family, is known to regulate the development and survival of a select population of neurons through the binding and activation of the TrkA receptor. Elevated levels of NGF have been associated with painful pathologies such as diabetic neuropathy and fibromyalgia. However, completely inhibiting the NGF signal could hold significant side eff...
