Three Surgical Cases of Cecal Volvulus.

Cecal volvulus (CV) is a relatively rare disease; however, it often requires emergency surgery due to the low success rate of endoscopic treatment, in contrast to sigmoid volvulus. The mechanism of CV involves a mobile cecum at the base, triggered by factors such as constipation, high-fiber diets, laxative use, history of laparotomy or laparoscopic surgery, pregnancy, and prior colonoscopy, which twists the ileocecal region. Although CV is a benign disease, it can be fatal if treatment is delayed, so it is crucial to understand the pathophysiology and treatment.

Postoperative Pyoderma Gangrenosum in a Laparoscopic Gastrectomy Port Site: A Case Report.

Background: Postoperative pyoderma gangrenosum (PPG) is a rare inflammatory skin disease of unknown etiology characterized by blistering and ulcerative lesions in postoperative wounds. Untreated pyoderma gangrenosum (PG) is potentially life-threatening; therefore, immediate and appropriate treatment is essential. Although PPG and surgical site infection (SSI) present similar clinical findings, they should be differentiated because of their conflicting treatment modalities.

Risk factors for sleep impairment in adult patients with chronic rhinosinusitis.

Objective: Although sleep impairment is reported by patients with chronic rhinosinusitis, the associated factors have not been well studied. Therefore, we determined the associated risk factors for sleep impairment in patients with chronic rhinosinusitis (CRS).

Methods: This study was a prospective cohort study.

Study of hemostasis procedures for posterior epistaxis.

Objective: Hemostasis is difficult in patients with bleeding emanating from the deep regions in the nasal cavity; however, there is no standard treatment method. We studied hemostasis procedures in patients who visited our outpatient department and presented with idiopathic epistaxis extending from the posterior nasal cavity to Kiesselbach's area.

Methods: The subjects were patients with epistaxis who visited our hospital between June 2008 and May 2010.

Withdrawal of Continuous Positive Airway Pressure Therapy after Malar Advancement and Le Fort II Distraction in a Case of Apert Syndrome with Obstructive Sleep Apnea.

Apert syndrome is a congenital syndrome characterized by craniosynostosis and craniofacial dysostosis, among other features, and is reported to cause obstructive sleep apnea (OSA) because of upper airway narrowing associated with midfacial dysplasia. We recently encountered a case involving a patient with Apert syndrome complicated by OSA who began to receive continuous positive airway pressure (CPAP) therapy at the age of 4. OSA resolved after maxillofacial surgery performed at the age of 11, and CPAP was eventually withdrawn.

Stem cell-conditioned medium accelerates distraction osteogenesis through multiple regenerative mechanisms.

Distraction osteogenesis (DO) successfully induces large-scale skeletal tissue regeneration, but it involves an undesirably long treatment period. A high-speed DO mouse model (H-DO) with a distraction speed twice that of a control DO model failed to generate new bone callus in the distraction gap. Here we demonstrate that the local administration of serum-free conditioned medium from human mesenchymal stem cells (MSC-CM) accelerated callus formation in the mouse H-DO model.

Risk factors for recurrent epistaxis: importance of initial treatment.

Objective: A retrospective study of risk factors for recurrent epistaxis and initial treatment for refractory posterior bleeding was performed. Based on the results, proposals for appropriate initial treatment for epistaxis by otolaryngologists are presented.

Methods: The data of 299 patients with idiopathic epistaxis treated during 2008-2009 were analyzed by multivariate logistic regression analysis.

Phase of nasal cycle during sleep tends to be associated with sleep stage.

Background And Objectives: The phenomena of periodic cycles of vascular engorgement on the nasal cavity mucosa that alternate between right and left sides are termed the "nasal cycle." The physiologic mechanisms underlying this cycle have not been entirely clarified, even more so during sleep. In this study, we measured the periodic patterns of the normal nasal cycle, not only during wakefulness but also during sleep.

Acinic cell carcinoma of minor salivary gland of the base of tongue that required reconstructive surgery.

Acinic cell carcinoma of minor salivary gland of the base of tongue is very rare. Squamous cell carcinoma is the most common tumor in the base of tongue. We present a patient with gigantic acinic cell carcinoma of the base of tongue.

Stromal cell-derived factor-1 enhances distraction osteogenesis-mediated skeletal tissue regeneration through the recruitment of endothelial precursors.

Distraction osteogenesis (DO) is a unique therapy that induces skeletal tissue regeneration without stem/progenitor cell transplantation. Although the self-regeneration property of DO provides many clinical benefits, the long treatment period required is a major drawback. A high-speed DO mouse model (H-DO), in which the distraction was done two times faster than in control DO (C-DO) mice, failed to generate new bone callus in the DO gap.
