In May 2016, it was proposed by the US athletes of the National Basketball Association (NBA) on television that the nociceptive-sympathetic coupling be required for pain sensations. Later, it was demonstrated that, via the activation of sympathetic outputs directly by the nociceptive neurons in laminae I and V of the dorsal spinal horn as well as those in periaqueductal grey (PAG) of brain, it was completed the nociceptive-sympathetic coupling in vertebrates. In this article, for the evolutionar...

The induced cessation of ventilation or suspension of external breathing is a common occurrence in anaesthetic practice. During the period of induced apnoea, there is no movement of the muscles of inhalation and lung volumes initially remain unchanged. Maintaining haemoglobin saturation during airway management is critical to guarantee the safety of patients. However, there has been little quantitative study of apnoea especially on the rate of change in oxygen saturation in relation to haemoglob...

Carotid cavernous fistula is an abnormal communication between the cavernous portion of the carotid artery and the venous bed of cavernous sinus with secondary increased pressure in the cavernous sinus leading to clinical presentations depending on the vascular and/or nervous structures involved in this injury process. The patient may present in the emergency room with proptosis, cranial nerve palsy, increased intraocular pressure, diplopia, decreased vision, and sometimes blindness in case of a...

We report a case of a 66-year-old female patient with ischemic cardiomyopathy, who was referred in Nephrology Department for the management of a renal impairment associated-severe hyponatremia, hypokalemia and hypochloremia that occurred after vomiting episodes evolving since 1 month. On admission, the patient was calm with a psychomotor retardation occurring in a context of moderate dehydration. Arterial blood gas analysis outlined a severe metabolic alkalosis. An extra-renal cause of these met...

In May 2016, it was suggested by the US athletes playing games of National Basketball Association (NBA) in television that the pain sensation might result from the post-sensory nociceptive-sympathetic coupling. In this re-view, it is attempted to newly delineate the underlying neural pathways for this post-sensory nociceptive-sympathetic coupling. Based on the con-temporary feedback neural circuits of pain transmission in spinal c ...

A 68-year-old woman with intercondylar fracture of the femur suffers massive (high risk) pulmonary embolism (PE) during surgery and is suc-cessfully treated with systemic thrombolysis. After limb exsanguinations with Esmarch bandage, the patient presents with sudden oxygen desaturation (99% to 80%) with subsequent dyspnea and hypotension. She is intubated and requires continuous adrenalin perfusion while the surgery is finished an ...

A 49 year old gentleman presented with intermittent bilateral knee swelling
for the past 37 years and was eventually diagnosed as primary hypertrophic
osteoarthropathy after secondary forms were excluded. This case illustrates
that the disease can present during childhood with an insidious onset and
progressively become more severe and that is when medical attention is
sought. Furthermore, the patient did not voluntarily report hi ...

The nasopharyngeal angiofibroma is an aggressive, vascular tumor that may
represent a challenge for the anesthesiologist by the risk of profuse bleeding.
We report the case of a 13 years old, 52 kg, ASA1, who was scheduled for the
resection of an angiofibroma invading facial sinuses and internal carotid
artery, and submitted to external carotid and internal maxillary arteries
embolization one day before surgery. Mallampati 2, prev ...

This is the case of a 76 y/o AA man with a past medical history of Hypertension
and Guillain Barre Syndrome (GBS), who presented for a median sternotomy and
excision of a thymic mass after workup for multiple episodes of syncope
revealed the thymic mass. Intraoperatively, the patient had 2 episodes of
cardiac arrest with asystole. He was adequately resuscitated and extubated. He
was later determined by Neurology to have severe autonomic dysfunction and not
a candidate for any elective surgery.

Following an accidental dural puncture during the placement of epidural
anesthesia, leakage of cerebrospinal fluid occurs. This leads to tugging on
intracranial pain-sensitive structures and causes a headache that is postural
in nature. According to radiology literature, the presence of retro spinal
fluid collections has been associated with the diagnosis of spontaneous
intracranial hypotension. The characteristic C1-C2 radiographic sign, called
the C1-C2 false localizing sign, can be found on m...
