To compare the efficiency of unilateral and bilateral transforaminal epidural steroid injections (TFESI) in patients with unilateral lumbar disc herniation (LDH). In this prospective randomized single-blinded study, patients with unilateral LDH were randomly divided into two groups: A unilateral TFESI group; and a bilateral TFESI group. The severity of pain and disability were assessed with the Numeric Rating Scale (NRS-11) and Oswestry Disability Index (ODI) at baseline, 1 week, 1 month, and 3 months after interventions.

Acute pancreatitis (AP) is a clinical condition that arises acutely in the pancreas through various inflammatory pathways due to multiple causes. Turkish Society of Gastroenterology Pancreas Working Group developed comprehensive guidance statements regarding the management of AP that include its epidemiology, etiology, clinical presentation, diagnostic criteria, disease severity, treatment, prognosis, local and systemic complications. The statements were developed through literature review, deliberation, and consensus opinion.

Article Synopsis
  • The study aimed to evaluate the prevalence of pancreatic steatosis (PS) using transabdominal ultrasonography in Turkish gastroenterology clinics and identify associated factors.
  • A total of 1,700 volunteers revealed a PS prevalence of 68.9%, with factors like age, BMI, and metabolic syndrome linked to its severity.
  • The study also found that 11.8% of PS cases were in lean individuals, who were generally younger and had lower metabolic risk factors compared to those with non-lean PS.

Aim: To review our experience with patients presenting with recurrent trigeminal neuralgia (TN) and who have undergone repeat microvascular decompression surgery (rMVD).

Material And Methods: This retrospective observational study was conducted at the Department of Neurosurgery at a university hospital. Patients who initially experienced complete pain relief after the first MVD but later had a recurrence of TN symptoms which required an rMVD were included in the study.

Article Synopsis
  • * Both treatments resulted in significant improvements in pain severity, headache duration, frequency of headaches, and reduced need for medication, but GON blocks were notably more effective.
  • * By the third month, patients receiving GON blocks experienced a greater reduction in headache intensity and disability compared to those receiving SPG blocks, indicating that GON block may be the more effective option for managing episodic migraines.

Objectives: The aim of this study was to investigate the pain type (nociceptive or neuropathic) and neuropathic pain components in patients with acute herpes zoster (HZ).

Methods: Patients with acute HZ referred to the outpatient Dermatology and Venereology clinic between January 2021 and January 2022 were retrospectively detected. The demographic data including gender and age, rash localization, pain severity, and neuropathic pain components were recorded.

A controlled release system that enables the sunlight-triggered release of a model agrochemical, abamectin (abm), is presented. The release system consists of polydopamine functionalized halloysite nanotubes (HNT-PDA) utilized as photothermal nanocarriers to encapsulate 25 wt % abm and 37 wt % lauric acid (LA), a phase change material, that acts as a heat-activable gatekeeper stopping or facilitating the abm release. When exposed to sunlight for 20 min at 1 and 3 sun light density, the temperature of the photothermal nanocarriers reaches 51 and 122 °C, respectively, which triggers the melting of LA and the consequent release of abm from the nanocarriers.

  • Acute pancreatitis (AP) is a leading gastrointestinal condition causing hospitalization, with a focus on evaluating its clinical features and adherence to international management guidelines.
  • The study analyzed 2,144 hospitalized AP patients in Turkey, finding that most cases were mild, with biliary causes being the most common, and an overall mortality rate of 1.6%.
  • Results indicate good predictive accuracy for severe cases using specific scoring systems, but show inconsistent adherence to treatment guidelines, particularly in administering prophylactic measures like NSAIDs and antibiotics.

Photothermal nanoparticles with light-to-heat conversion properties have gained interest in recent years and have been used in a variety of applications. Herein, indocyanine green (ICG), which is commonly employed as a photothermal agent suffering from low photostability, was loaded into halloysite nanotubes (HNTs) resulting in photothermal HNT-ICG nanohybrids. The photothermal heating patterns of the prepared photothermal nanohybrids as a result of near-infrared (NIR) irradiation were carefully examined.

Photothermal materials and coatings which can create temperature elevations under light irradiation can be utilized in various applications requiring remote heating. Here, multiwalled carbon nanotubes (MWNT) were incorporated into waterborne polyurethane (PU) to obtain photothermal coatings with light-to-heat conversion properties. Resulting PU-MWNT coatings were demonstrated to heat up to 80 °C under sunlight irradiation at 2 sunlight density for 18 min.

Objective: The study aimed to determine whether maternal serum haptoglobin values could have an effect on predicting diagnosis and neonatal outcomes in preeclampsia and HELLP syndrome.

Materials And Methods: Hundred sixteen pregnant women who met the inclusion criteria were included in the study. To evaluate whether serum haptoglobin level in maternal blood could be used in early diagnosis of preeclampsia and HELLP syndrome, 49 pregnant women diagnosed with preeclampsia and 13 pregnant women diagnosed with HELLP syndrome were included in the study group, and 54 healthy pregnant women in the control group.

Conjugation, the process by which conjugative plasmids are transferred between bacteria, is regarded as a major contributor to the spread of antibiotic resistance, in both environmental and clinical settings. Heavy metals are known to co-select for antibiotic resistance, but the impact of the presence of these metals on conjugation itself is not clear. Here, we systematically investigate the impact that five heavy metals (arsenic, cadmium, copper, manganese, and zinc) have on the transfer of an IncF conjugative plasmid in .

In this study we aim to examine genotypic structures in terms of the -casein (CSN3) gene locus in 70 head of Simmental cattle raised in a private enterprise in Erzurum to determine the distribution of genotypes and allele frequencies in cattle in terms of related genes and to correlate the determined genotypes with some performance characteristics. CSN3/HinfI gene polymorphisms were identified in DNA isolated from blood samples taken from Simmental cattle used in the study using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The frequency of the AA, AB, and BB genotype of the CSN3 gene in the population was 57.

This study investigates the effects of human capital, bio-capacity, energy use, and economic growth on the ecological footprint of G20 countries for the period 1970-2016, using the panel dynamic common correlated effects (DCCE) model. In the study, the G20 was considered in two groups, as developed and emerging economies. According to the DCCE estimation results, the long-term impact of human capital on the ecological footprint is negative and statistically strong in the developed economies while it is insignificant in the emerging economies.

The dark-rim artifact (DRA) remains an important challenge in the routine clinical use of first-pass perfusion (FPP) cardiac magnetic resonance imaging (cMRI). The DRA mimics the appearance of perfusion defects in the subendocardial wall and reduces the accuracy of diagnosis in patients with suspected ischemic heart disease. The main causes for DRA are known to be Gibbs ringing and bulk motion of the heart.
