Article Synopsis
  • Retrograde intrarenal surgery (RIRS) is increasingly used to treat renal stone disease in children, but stone-free rates vary, and there's limited data on how long it takes to achieve this status.
  • A study evaluated 105 children who underwent RIRS, revealing that 42.2% achieved stone-free status after one procedure, while 75.5% reached this status within an average of 12.25 months, with variations based on stone types.
  • The findings emphasize the importance of long-term follow-up for pediatric patients after RIRS, as achieving a stone-free status can take over a year.

Background/aim: This study compares the effectiveness of teletherapy and face-to-face voice therapy in treating vocal fold nodules (VFNs) among female patients.

Methods: Fifteen individuals who met the inclusion criteria were enrolled in the study and randomized, but after some dropouts, the study was completed with ten patients diagnosed with VFNs. Six patients received teletherapy while four were treated with face-to-face voice therapy.

Objective: This study investigated the effects of hospitalization in the neonatal intensive care unit (NICU) due to congenital pneumonia (CP) on maternal stress and attachment, focusing on how the duration of invasive and noninvasive mechanical ventilation, length of NICU stay, and postpartum breastfeeding initiation time influence mother-infant attachment.

Methods: Conducted among 30 mothers of 3-month-old infants admitted to the NICU with CP and a control group (n = 30), it analyzed the impact of medical intervention durations and breastfeeding initiation on maternal stress and attachment using statistical methods.

Results: The maternal stress in the NICU group was significantly higher than in the control group ( = .

Introduction: Although long-term survival in patients with metastatic colorectal cancer (mCRC) is limited, treatments for third-line and later treatment are now recommended. We describe a patient who achieved long-term survival when they received third-line treatment with trifluridine/tipiracil (FTD/TPI).

Case Presentation: The woman who was 52 years old at diagnosis of adenocarcinoma of the right colon (T3/N0/M1) with metastases to the lung, liver, ovary, and other soft tissues received first-line fluoropyrimidine-based chemotherapy (FOLFOX/FOLFIRI plus bevacizumab) intermittently for approximately 8.

CIC-rearranged sarcoma (CRS) is a group of high-grade undifferentiated small round cell sarcomas examined as a separate entity in the current WHO classification; since it shows more aggressive clinical behavior and distinct morphological and molecular features compared to Ewing sarcoma (ES). As CCNE1 expression is associated with tumor growth in CIC::DUX4 sarcomas, we aimed to demonstrate the value of cyclin E1 expression in CRS. Cyclin E1 immunohistochemistry and break-apart FISH for EWSR1 and CIC gene rearrangements were performed on 3-mm tissue microarrays composed of 40 small round cell tumors.

Article Synopsis
  • Colorectal cancer is a major global health issue, and in Turkey, a study was conducted to assess the effectiveness of second-line treatments for patients with RAS wild-type metastatic colorectal cancer.
  • The research involved a retrospective analysis of 588 patient records from 28 centers, categorizing them by the type of biological treatments received: anti-EGFR and anti-VEGF.
  • Results showed no significant differences in overall survival or progression-free survival among the different treatment groups, indicating similar effectiveness of the biological agents in second-line treatments.

Cadmium (Cd) is a ubiquitous environmental pollutant, and Cd exposure harms human health, agriculture, and animal husbandry. The present study aimed to investigate the potential protective effect of dietary supplementation of calcium tetraborate (CTB) on productive performance, oxidative stress, cecal microflora, and histopathological changes in quail exposed to Cd. A total of one hundred twenty, 6-week-old Japanese quail (four females and two males/replicate) were divided into four groups (30 quails/group): the control group (feeding basic diet), CTB group (basic diet containing 300 mg/kg CaBO, 22.

Background: The management of early rectal cancer is different from that of colon cancer in terms of radiotherapy (RT) requirements or neoadjuvant treatment. It is not clear how the course of rectal cancer differs from that of the colon in a metastatic setting or how it should be approached differently. This study aimed to evaluate outcomes after combining downsizing chemotherapy (CTx) with rescue surgery.

Purpose: The most important point in cases of ureteropelvic junction obstruction (UPJO) is to decide on the need and timing of surgical treatment. Renal damage may become irreversible as the duration of the obstruction is prolonged. Worsening of hydronephrosis and decrease in renal parenchymal thickness after pyeloplasty may herald an irreversible renal damage.

Objective: Diabetes is an important endocrinological disease that has an increasing incidence in the world and affects all biological tissues including testicles. Therefore, this study aimed to reveal the histological and biochemical effects of vitamin D on irisin, apoptosis, total antioxidant status (TAS), and total oxidant status (TOS) in testicular tissues of rats with experimental diabetes.

Materials And Methods: 41 male Wistar rats, 8-10 weeks old, weighing between 200-220 g, were included in the study as the following groups: control group (n=7; no treatment), sham group [only sodium citrate buffer (SCB)] [n=7; single dose 0.

The aim of this study was to evaluate the efficacy of electroacupuncture in acute and chronic phases of radial and ulnar nerve injuries in histopathological, immunohistochemical and biochemical aspects. In the study, the rabbits were divided into four groups namely acute nerve injury (ANI) group, chronic nerve injury (CNI) group, positive control (PC) group and negative control (NC) group. In the ANI, CNI and PC groups, damage was created on the nervus radialis and nervus ulnaris by applying pressure for 60 seconds using a hemostatic forceps under anesthesia.

Pneumonia is a fatal disease that appears in the lungs and is caused by viral or bacterial infection. Diagnosis of pneumonia in chest X-ray images can be difficult and error-prone because of its similarity with other infections in the lungs. The aim of this study is to develop a computer-aided pneumonia detection system to facilitate the diagnosis decision process.
