Modern opportunities to the diagnosis and treatment of recurrent respiratory papillomatosis with tracheal, bronchial and lung involvement

Recurrent respiratory papillomatosis (RRP) is a rare disease caused by the human papilloma virus (HPV) and characterized by recurrent growth of benign papillomas in the upper and lower respiratory tract. The aim of the study was to increase the effectiveness of RRP treatment using the wide spectrum of diagnostic and therapeutic bronchological methods. 29 patients aged from 18 to 72 years old with RRP were included. In three patients - the juvenile form of RRP was diagnosed, in the remaining- the adult. Flexible bronchoscopy with biopsy and histological examination with microscopic staining and immunohistochemistry (Ki67, p53, p63) were done. Polymerase chain reaction revealed 6, 11, 16, 18 types of HPV. Tracheal RRP was diagnosed in 19 patients, bronchial - in 5, larynx, trachea and lung parenchyma were involved in 5 patients. 10 patients underwent LASER photo-destruction of papillomas, 7 had electrosurgical destruction in combination with LASER or argon plasma coagulation, 4 patients had argon plasma coagulation, and 7 patients received photodynamic therapy. Human papilloma virus was established in all patients by polymerase chain reaction. The most often, 6 and 11 types were identified, but in cases of cancer transformation -16 and 18 types. As a result of this treatment 58.6% of patients achieved full reduction of papillomas, 27.5% - partial reduction. In 4 patients, the transformation of RRP into cancer was diagnosed. The use of PDT as recurrence prevention treatment cont...

Authors: Li W, Zhou Y, Shang C, Sang H, Zhu H Abstract Background: Proton pump inhibitor (PPI) and other acid-suppressing drugs are widely used in the treatment of gastrointestinal ulcer, upper gastrointestinal bleeding, gastritis, and gastric cancer (GC). About 80% of GC patients receive acid suppression treatment. PPI suppresses the production of gastric acid by inhibiting the function of H+/K+-ATPase in gastric parietal cells and raises the pH value to achieve therapeutic purposes. Some studies have found that PPI had a certain antitumor effect in the proliferation and apoptosis of tumor cells. But the effects o...

Authors: Quaglino F, Manfrino L, Cestino L, Giusti M, Mazza E, Piovesan A, Palestini N, Lauro C, Castellano E Abstract Parathyroid carcinoma (PC) is a rare disease responsible for about 1% of primary hyperparathyroidism (PHPT) cases. PC usually has an indolent course, tough to differentiate from the benign causes of PHPT, and the only certain diagnosis is histologic. The gold standard surgical treatment is the en bloc resection associated with the homolateral thyroid loboistmectomy. The aim of this study was to underline the main differences between PC and benign PHPT, along with gathering epidemiological knowledge...

This study aims to analyze survival rates in acute lymphocytic leukemia in the city of São Paulo, Brazil, from 1997 to 2013, according to sex, age bracket, and administrative region. This was a longitudinal study to calculate survival rates. Data on new cases of leukemia in the age bracket 0 to 14 years of age were collected from the database in the Population-Based Cancer Registry of the city of São Paulo. Population and mortality data were obtained from the Brazilian Health Informatics Department. The sample included children 0 to 14 years of age diagnosed with leukemia from 1997 to 2013, living in the city...

Authors: Nguenang GS, Ntyam ASM, Kuete V Abstract Lycopersicon esculentum (tomato) is a plant widely used in Africa like food and to solve many health problems. The methanol crude extract of tomato recently demonstrated a good antiproliferative effect on many human cancer cell lines. The aim of this research was to evaluate the acute toxicity and subacute oral toxicity of methanolic extract from leaves of this plant. These toxicities were evaluated based on the OECD (Organization for Economic Cooperation and Development) guidelines. The assay of acute toxicity was performed using a total of 3 female rats, which rec...

In this study, all 135 patients received CM treatment for at least 36 months. The response rates for CM treatment were 81.53% (106/130) for hematological improvement in 130 MDS-RCMD patients and 80% (4/5) for bone marrow CR in 5 MDS-RAEB patients, respectively. The Human Methylation 850K BeadChip showed that 115 genes (50.88%) were aberrantly hypomethylated in 5 MDS patients compared with 3 healthy individuals. GO-analysis showed that these hypomethylated genes participated in many cancer-related biological functions and pathways. Furthermore, 60 genes were hypermethylated and the protein expression level of DNMT1 was sign...

This study aimed to analyze the effects of Qihuang decoction combined with enteral nutrition on nutrition and the immune function of postoperative gastric cancer. Methods: 120 patients with postoperative gastric cancer in the study group and 117 in the control group were selected as the study subjects from our hospital at random. Indications of nutrition and immune and the rates of complications were compared the day before surgery and 1, 3, 7, and 14 days after surgery. Results: Indications of nutrition except hemoglobin (HB) in the study group were significantly higher than those before operation and the albumin ...
