Background: Esophageal candidiasis is associated with conditions that cause an immune depression. It is a defining disease for AIDS, is observed in poorly controlled diabetics, in patients with renal or hepatic failure, in patients with cancer and in subjects using medications causing immunosuppression or broad spectrum antimicrobials.
Aim: To report the features of 10 immunocompetent patients with esophageal candidiasis.
Patients And Methods: Six males and four females aged between 48 and 82 years, without conditions associated with immunosuppression, in whom an esophageal candidiasis was found on an upper gastrointestinal endoscopy. Delayed skin hypersensitivity to eight antigens, lymphocyte subpopulations, yeast phagocytosis and neutrophil chemotaxis were measured.
Results: Six patients had a low CD4 lymphocyte count and seven had a low CD8 count. Seven patients were anergic on skin hypersensitivity challenge. Yeast phagocytosis was abnormal in one patient and neutrophil chemotaxis was abnormal in two. Humoral immunity was normal in all subjects. All patients were treated with oral fluconazole in doses of 150 mg/day for 14 days, with complete resolution of candidiasis in all.
Conclusions: Patients with esophageal candidiasis, have frequent alterations of cellular immunity, that must be diagnosed and treated.

Objective: While the association of a syrinx with a tethered spinal cord in the context of VACTERL (vertebral defects [V], imperforate anus or anal atresia [A], cardiac malformations [C], tracheoesophageal defects [T] with or without esophageal atresia [E], renal anomalies [R], and limb defects [L]) association is known, the incidence of idiopathic syrinxes among these patients has not previously been reported. The authors aimed to characterize the incidence of syrinxes and the pattern of congenital anomalies in pediatric patients with VACTERL association, with a specific focus on the presence of idiopathic syrinxes in this population.
Methods: An institutional database was retrospectively queried for all pediatric patients with VACTERL association.

While acute upper gastrointestinal bleeding (AUGIB) remains clinically critical, the etiology of bleeding and risk factors for mortality remain uncertain. This study aimed to evaluate the underlying causes of AUGIB and identify risk factors associated with fatality. A retrospective survey was conducted in a major clinical hospital in Shanghai, where inpatients diagnosed with AUGIB were meticulously collected and analyzed.

Importance: Upper gastrointestinal cancers such as gastric and esophageal cancers are rare malignancies with poor prognosis because it is usually diagnosed in latter stages. Presenting symptoms are frequently presumed pregnancy related rather than malignancy related. This review will raise awareness to consider these aggressive cancers in evaluating gastrointestinal complaints during pregnancy.

Background: Neoadjuvant chemotherapy is standard for advanced esophageal squamous cell carcinoma, though often ineffective. Therefore, predicting the response to chemotherapy before treatment is desirable. However, there is currently no established method for predicting response to neoadjuvant chemotherapy.

Purpose: The double-flap technique (DFT) is an anti-reflux reconstruction procedure performed after proximal gastrectomy (PG), but its complexity and high incidence of anastomotic stenosis are problematic. We conducted this study to demonstrate the efficacy of robot-assisted DFT, with refinements, to address these issues.
Methods: Surgical outcomes were compared between the following procedures modified over time at our institution: conventional open DFT (group O, n = 16); early robotic DFT (group RE, n = 19), which follows the conventional open PG approach; and late robotic DFT (group RL, n = 21), which incorporates refinements to the early robotic DFT technique by exploiting more of the robotic capabilities available.
