A 54-year-old male was diagnosed as having synchronous quadruple early stage lung cancer. All four tumors showed the same histologic type of in-situ or microinvasive squamous cell carcinoma, but existed independently in different bronchi. Photodynamic therapy of these four lesions was successfully performed by fiberoptic bronchoscopy because of the patient's poor pulmonary function. The patient...

BACKGROUND Helicobacter pylori infection causes lifelong gastritis and is associated with the development of peptic ulcer disease, MALT lymphoma and gastric cancer. Many patients benefit from H. pylori eradication therapy. PPI-triple therapy is recommended as initial therapy. Quadruple therapy, with a PPI, bismuth, and two antibiotics, used to be recommended as second-line therapy, but can no l...

A Steiner quadruple system (X, B) is said to be (1, 2)-resolvable if its blocks can be partitioned into r parts such that each point of X occurs in exactly two blocks in each part. The necessary condition for the existence of (1, 2)-resolvable Steiner quadruple systems RSQS(1, 2, v)s is v ≡ 2 or 10 (mod 12). Hartman and Phelps in [A. Hartman, K.T. Phelps, Steiner quadruple systems, in: J.H. Din...

PURPOSE OF REVIEW The article will give an overview on reasons for treatment failure and tries to show new concepts for Helicobacter pylori treatment. RECENT FINDINGS Several new treatment options or modifications of already established regimens have been introduced to overcome treatment failure. Antibiotic resistance to H. pylori is the key factor for treatment failure. At the moment, standa...

BACKGROUND The purpose of the present paper was to evaluate the efficacy and tolerability of amoxicillin-clavulanate and tetracycline-based quadruple therapy as an alternative second-line treatment for H. pylori infection. METHODS The study subjects consisted of 54 patients infected with H. pylori, in whom initial triple therapy had failed. Subjects were randomized to receive the following 7-...

Childrenwith Helicobacter infection need treatment. The aim of treatment is elimination of H.Pylori. Most patients with this infection are asymptomatic and without peptic disease. Treatment and management of these patients are controversy. Conventional Treatment: The best treatment for H. pylori eradication regimens should have cure rates of at least 80%, be without major side effects, and indu...

Treatments with bismuth-containing quadruple therapy (QT), sequential therapy (ST), or concomitant therapy (CT) have been proposed as empirical first-line regimens for Helicobacter pylori. We compared the efficacy and tolerability of 10 days bismuth-containing quadruple QT, 10 days ST, and 10 days CT with as first-line treatments for H. pylori in a randomized crossover study. The subjects were ...
