Objective: To evaluate the pain or physiological stress caused during minimally invasive surfactant therapy (MIST) to very preterm neonates.
Methods: In this prospective observational study conducted in a tertiary NICU, very preterm neonates were assessed for pain using Premature Infant Pain Profile-Revised (PIPP-R) score before, during and after MIST. Changes in the heart rate and oxygen saturation were also recorded during the procedure.
Results: 23 neonates who received MIST were assessed for pain using PIPP-R. Mean (SD) PIPP-R score during MIST was 3.87(1.3), before; 12.83 (1.9), during; and 6.26 (1.0), after the procedure, respectively (all P<0.001). Heart rate and oxygen saturation were also significantly reduced during MIST (P<0.001).
Conclusion: The high PIPP-R scores during surfactant administration suggest that MIST can cause moderate to severe pain/discomfort and significant physiological stress in very preterm infants.

Background: Postoperative pain remains a significant problem in patients undergoing donor nephrectomy despite reduced tissue trauma following laparoscopic living donor nephrectomy (LLDN). Inadequately treated pain leads to physiological and psychological consequences, including chronic neuropathic pain.
Materials And Methods: This randomized controlled double-blinded trial was conducted in sixty-nine (n = 69) participants who underwent LLDN under general anesthesia.

Pain and itch are unpleasant and distinct sensations that give rise to behaviors such as reflexive withdrawal and scratching in humans and mice. Interestingly, it has been observed that pain modulate itch through the neural circuits housed in the brain and spinal cord. However, we are yet to fully understand the identities of, and mechanisms by which specific neural circuits mediate pain-induced modulation of itch.

Background: Traumatic brain injury (TBI) disrupts normal brain tissue and functions, leading to high mortality and disability. Severe TBI (sTBI) causes prolonged cognitive, functional, and multi-organ dysfunction. Dysfunction of the autonomic nervous system (ANS) after sTBI can induce abnormalities in multiple organ systems, contributing to cardiovascular dysregulation and increased mortality.

Neurosurgical operations treat involuntary movement disorders (MvDs), spasticity, cranial neuralgias, cancer pain, and other selected disorders, and implantable neurostimulation or drug delivery devices relieve MvDs, epilepsy, cancer pain, and spasticity. In contrast, studies of surgery or device implantations to treat chronic noncancer pain or mental conditions have not shown consistent evidence of efficacy and safety in formal, randomized, controlled trials. The success of particular operations in a finite set of disorders remains at odds with disconfirming results in others.

Background: Patients with somatoform pain experience physical pain that cannot be attributed to any underlying medical or physiological cause, and it is often thought to be related to psychological factors. Health professionals encounter difficulties identifying this specific type of chronic pain, leading to suboptimal treatment strategies. Therefore, we aimed to describe the characteristics of patients with somatoform pain, to support the identification of affected patients.
