Radiological findings associated with postoperative wound infection after extraction of impacted mandibular third molar: A retrospective study.

Introduction: Studies directly relating radiological findings to the risk of postoperative wound infection (PWI) in impacted mandibular third molars (M3) are limited and poorly understood. This study aimed to clarify the radiological risk of PWI.

Materials And Methods: Twenty-six patients who developed PWI after M3 extraction were retrospectively analyzed using orthopantomography (OPG) and computed tomography (CT) before M3 extraction to determine the association between M3 impaction status and PWI.

[Eight mm Port-Site Hernia Following Robot-Assisted Abdominoperineal Resection for Rectal Cancer-A Case Report].

A 70s woman with a history of asthma and dyslipidemia underwent a robot-assisted abdominoperineal resection for rectal cancer. The ports were placed as per the method of Shizuoka Cancer Center and no intraoperative complications were observed. The colostomy was constructed in the left lower abdomen by the retroperitoneal route.

[Long-Term Survival of a Patient with Hepatocellular Carcinoma after Surgical Resection of Metachronous Hilar Lymph Node Metastases].

The recurrence of hepatocellular carcinoma(HCC)is primarily due to intrahepatic metastases. Additionally, extrahepatic HCC metastases most commonly occurs in the lungs, lymph nodes, adrenal glands, and bones. Systemic chemotherapy is the standard treatment for extrahepatic metastases.

[A Case of Synchronous-Metachronous Cancer of the Rectum, Stomach, Pharynx, Esophagus and Small Intestine].

A 71-year-old man presented with the chief complaint of fecal occult blood. Based on imaging studies, the patient was diagnosed advanced rectal cancer. He received laparoscopic low anterior resection.

Prognostic Significance of Sarcopenia in Patients with Esophagogastric Junction Cancer or Upper Gastric Cancer.

Background: The association between sarcopenia and postoperative outcomes for patients with gastrointestinal malignancies remains controversial. This study aimed to assess the impact of sarcopenia on short- and long-term outcomes after surgery for esophagogastric junction cancer (EGJC) or upper gastric cancer (UGC).

Methods: The study reviewed 148 patients with EGJC or UGC who underwent surgical resection.

Prognostic Significance of Postoperative Complications After Curative Resection for Patients With Esophageal Squamous Cell Carcinoma.

Objective: The objective of this study was to elucidate the impact of postoperative complications on long-term survival after curative resection for esophageal squamous cell carcinoma.

Background: The relation between postoperative complications and long-term survival after curative surgery for esophageal squamous cell carcinoma is controversial; thus, this issue should be resolved with a large-scale, well-designed study.

Methods: Clinicopathological features and survival of 580 consecutive patients who received curative resection for esophageal squamous cell carcinoma were investigated according to the development of postoperative pulmonary complications and anastomotic leakage.

Clinicopathological Features of Cervical Esophageal Cancer: Retrospective Analysis of 63 Consecutive Patients Who Underwent Surgical Resection.

Objective: The objectives of this retrospective study were to elucidate the clinicopathological features and recent surgical results of cervical esophageal cancer.

Summary Background Data: Cervical esophageal cancer has been reported to have a dismal prognosis. Accurate knowledge of the clinical characteristics of cervical esophageal cancer is warranted to establish appropriate therapeutic strategies.

Prognostic impact of MutT homolog-1 expression on esophageal squamous cell carcinoma.

MutT homolog-1 (MTH1) is a pyrophosphatase that acts on oxidized nucleotides and hydrolyzes 8-oxo-2'-deoxyguanosine triphosphate in deoxynucleoside triphosphate pool to prevent its incorporation into nuclear and mitochondrial DNA, result in reduce cytotoxicity in tumor cells. MTH1 is overexpressed in various cancers and is considered as a therapeutic target. Environmental factors such as cigarette smoking and alcohol consumption are critical risk factors for the development and progression of esophageal squamous cell carcinoma (ESCC), suggesting that oxidative stress contributes to the pathogenesis of ESCC.

Synthesis of nucleobase-caged peptide nucleic acids having improved photochemical properties.

A nucleobase-caged peptide nucleic acid (PNA) having a (6-bromo-7-methoxycoumarin)-4-ylmethoxycarbonyl (Bmcmoc) caging group was newly synthesized. The Bmcmoc-caged PNAs were photolyzed to produce parent PNAs with a high photochemical efficiency. Introduction of a single Bmcmoc group was sufficient to suppress polymerase chain reaction (PCR) clamping activity and triplex invasion complex formation.
