Hidradenitis suppurativa (HS) is a chronic, recurrent inflammatory disease characterized by painful lesions such as nodules, abscesses, and sinus tracts, primarily affecting intertriginous areas. Traditional treatments range from antibiotics and hormonal therapies to biologics and surgical options. Recently, lasers and light-based treatments has gained attention as a non-systemic treatment for HS, targeting hair follicles to potentially alleviate symptoms and improve quality of life.

Objective: To investigate the effect of embolic protection device (EPD) use on periprocedural complications in patients with carotid artery stenosis with anatomical variations.

Method: The study retrospectively evaluated 185 patients who consecutively underwent carotid artery stenting between November 2020 and December 2023. Forty-four patients with difficult anatomical structures, anatomical variations in the common carotid artery (CCA) and internal carotid artery (ICA) (tortuosity, kinking, or coiling), and a CCA-ICA angle of >60 degrees were included in the sample.

  • The study aimed to compare the effectiveness of fluoroscopically guided transforaminal epidural steroid injection (TESI) in reducing pain for patients with ipsilateral early versus late recurrent lumbar disc herniation (RLDH).
  • A total of 738 patients with radicular pain were analyzed, with TESI administered to 390 for early RLDH and 346 for late RLDH, and follow-ups were done 12 weeks post-treatment.
  • Results showed that TESI significantly reduced pain more effectively in early RLDH patients (mean VAS score dropping from 85.44 to 20.16) compared to late RLDH patients (mean VAS score dropping from 72.82 to

Objectives: Our aim is to estimate the long-term neurological sequelae and prognosis in term neonatal asphyxia treated with hypothermia via volumetric apparent diffusion coefficient (ADC) map histogram analysis (HA).

Methods: Brain MRI studies of 83 term neonates with asphyxia who received whole-body hypothermia treatment and examined between postnatal (PN) fourth and sixth days were retrospectively re-evaluated by 2 radiologists. Volumetric HA was performed for the areas frequently affected in deep and superficial asphyxia (thalamus, lentiform nucleus, posterior limb of internal capsule, corpus callosum forceps major, and perirolandic cortex-subcortical white matter) on ADC map.

  • - The study focuses on helping burn patients develop self-care strategies during the discharge phase to enhance self-management and minimize health complications.
  • - It investigates the specific learning needs of these patients related to pre-discharge care, utilizing surveys completed by individuals in a burn unit hospital in Turkey.
  • - Findings reveal that patients have high learning needs, influenced by factors like education level, marital status, experience with companions, and body mass index; thus, individualized discharge training is recommended.

Indole-chalcone hybrids have burst into prominence as potent weapons in the battle against pain and inflammation due to their unique features, allowing these ligands to form pivotal interactions with biological targets. In this context, the base-catalyzed Claisen-Schmidt condensation of 3',4'-(methylenedioxy)acetophenone with heteroaromatic aldehydes carrying an indole scaffold yielded new chalcones (-). The central and peripheral antinociceptive activities of all chalcones (compounds -) at the dose of 10 mg/kg (.

The double-strand break (DSB) repair pathway called microhomology-mediated end-joining (MMEJ) is thought to be dependent on DNA polymerase theta (Polθ) and occur independently of nonhomologous end-joining (NHEJ) factors. An unresolved question is whether MMEJ is facilitated by a single Polθ-mediated end-joining pathway or consists of additional undiscovered pathways. We find that human X-family Polλ, which functions in NHEJ, additionally exhibits robust MMEJ activity like Polθ.
