May dexpanthenol, platelet-rich plasma, and thymoquinone provide new hope to maintain liver regeneration after partial hepatectomy?

Background/aims: Complete liver regeneration may not always be possible after liver injuries and/or partial liver resection. The present study investigated the effects of dexpanthenol, platelet-rich plasma (PRP), and thymoquinone on liver regeneration in rats after partial hepatectomy (PH).

Materials And Methods: A total of 34 Wistar albino rats, each weighing 250-280 g, were randomly separated into four groups.

Diagnosing atypia of undetermined significance in thyroid fine needle aspiration samples using nuclear scoring.

Background: Atypia of undetermined significance (AUS) is an indeterminate category in the Bethesda system for reporting thyroid cytopathology. Cytological features described as atypia are not always observed in every case, and it is difficult to determine how the small population of cells with enlarged nuclei, a few grooves, and rare elongated nuclei should be classified. Therefore, there is inter-intra observer variability considering these cell types, even though the cytological criteria are well defined.

Platelet-Rich Plasma May Offer a New Hope in Suppressed Wound Healing When Compared to Mesenchymal Stem Cells.

Background: The present study investigated the effectiveness of platelet-rich plasma (PRP) and mesenchymal stem cells (MSCs) in wound healing suppressed by corticosteroid in rats.

Methods: Forty rats were separated into four groups. To disrupt the wound-healing processes, intraperitoneal single dose 10 mg/kg methylprednisolone was administered to all rats with the exception of Sham-S group.

Rare Plasmacytoid Urothelial Carcinoma of the Bladder: Two Case Reports.

Plasmacytoid urothelial carcinoma is a rare and aggressive form of urothelial carcinoma characterized with delayed presentation and poor prognosis. Very few cases of this carcinoma have been reported in the literature. Here, we report and discuss two cases of bladder plasmacytoid urothelial carcinoma of a 57-year-old male presented with renal colic, and a 33-year-old female presented with macroscopic hematuria.

The effect of mesenchymal stem cell use on intra-abdominal adhesions in a rat model.

Purpose: Intra-abdominal adhesions (IAA) are among the most frequently seen pathologies in general surgery practice with an increased morbidity and mortality. In the present study, we investigated the effect of locally applied mesenchymal stem cells (MSCs) on IAA.

Methods: Twenty-four Wistar Albino rats were used in the study.

ERRATUM: Correction of funding statement in ACKNOWLEDGEMENTS section. Effectiveness of thymoquinone, zeolite, and platelet-rich plasma in model of corrosive oesophagitis induced in rats.

Effectiveness of thymoquinone, zeolite, and platelet-rich plasma in model of corrosive oesophagitis induced in rats.

Purpose: The effectiveness of platelet-rich plasma (PRP), thymoquinone, and zeolite in corrosive esophageal burns was investigated in a rat model.

Methods: Four groups were comprised as containing 10 rats in each group. For group I, oesophagitis was induced and no other procedure was performed (control group).

The effects of scalpel, harmonic scalpel and monopolar electrocautery on the healing of colonic anastomosis after colonic resection.

Purpose: In our study, the effects of harmonic scalpel, scalpel, and monopolar electrocautery usage on the health and healing of colon anastomosis after resection was investigated.

Methods: In this study, 120 female albino Wistar rats were divided into 3 groups each containing 40 rats. Group A, resection with scalpel; group B, resection with monopolar electrocautery; group C, resection with harmonic scalpel.

Postmenopausal spontaneous uterine perforation: Case report.

Spontaneous uterine rupture and generalized peritonitis caused by pyometra occurs rarely with high morbidity and mortality. A correct and definite diagnosis can be made with laparotomy or laparoscopy. The clinical findings of perforated pyometra are similar to perforation of the gastrointestinal tract and gynecologic symptoms are less frequent, which makes preoperative diagnosis difficult.

Comparison of Conjunctival Cytological Alterations following Conventional and Sutureless Sclerotomies.

Purpose: To assess the alterations in conjunctival impression cytology following 23-gauge transconjunctival sutureless versus conventional pars plana vitrectomy.

Patients And Methods: Sixty consecutive patients were enrolled in the study. Conjunctival impression cytology was performed on 30 eyes (of 30 subjects) with 23-gauge transconjunctival sutureless vitrectomy and on 30 eyes (of 30 subjects) with conventional vitrectomy.

Fine-needle aspiration of follicular patterned lesions of the thyroid: diagnosis, management, and follow-up according to thyroid Bethesda system.

Objective: The goal of this study was to report an experience with thyroid fine-needle aspiration (FNA) cases that can be placed into National Cancer Institute-designated thyroid FNA diagnostic categories for follicular patterned lesions divided into three diagnostic categories: follicular lesion of undetermined significance/atypia of undetermined significance (AUS/FLUS), suspicious for follicular neoplasm (SFON), and suspicious for malignancy.

Study Design: The study cohort included 4,284 cases for the period between January 2007 and July 2011 and all available follow-up data was obtained. All cases classified as 'atypical' and 'rule out follicular neoplasm' were included in the AUS/FLUS category (n = 3,903), whereas cases classified as 'suspicious for' or 'consistent with follicular or Hürthle cell neoplasm' (n = 381) were included in the SFON diagnostic category and compared with histopathologic follow-up.

An unusual cause of unilateral hydronephrosis: invasive colonic amebiasis.

A 62-year-old man was admitted to our hospital with complaints of abdominal pain and rectal bleeding. Although the colonoscopic examination was highly suggestive of a carcinoma, the histopathological examinations were consistent with chronic inflammation. CT examination revealed a solid lesion from cecum to the ascending colon with right urethral invasion.
