Objective: To compare the incision and drainage of perianal abscess (ID) without fistulotomy with Gabriel procedure (GP) in neonates and infants with perianal abscess and fistula-in-ano.

Material And Methods: A single-center retrospective comparative study included neonates and infants aged 1-12 months with first occuring perianal abscess and fistula-in-ano. Postoperative follow-up was 1 year.

Article Synopsis
  • This study explores different methods for modeling electron density and electrostatic potential in organometallic complexes, particularly focusing on iron(III) acetylacetonate (FeAcAc) using electron diffraction (ED) data.
  • The research compares the independent atom model (IAM) and the transferable aspherical atom model (TAAM), demonstrating that TAAM provides a more accurate representation of scattering factors and improves model fitting.
  • Results showed significant improvements in fitting statistics (R values), indicating that TAAM outperforms IAM by providing better results in both 3D electron diffraction and single-crystal X-ray diffraction, especially in low-resolution data.

Hydrated copolymers of -vinylpyrrolidone (VP) with triethylene glycol dimethacrylate as a promising platform for biologically active compounds (BAC) were investigated by different physical chemical methods (dynamic light scattering, infrared spectroscopy, thermal gravimetric analysis, and differential scanning calorimetry) and the quantum chemical modeling of water coordination by the copolymers in a solution. According to the quantum chemical simulation, one to two water molecules can coordinate on one O-atom of the lactam ring of VP units in the copolymer. Besides the usual terminal coordination, the water molecule can form bridges to bind two adjacent C=O groups of the lactam rings of VP units.

This open prospective randomized parallel-group comparative study included 43 patients with moderate or severe chronic obstructive pulmonary disease (COPD). The patients of active working age were referred to the disability groups II-III based on the average forced expiratory volume in 1 second (1.70+/0.

Aim: To elucidate efficacy of a combination almitrine+thiotropium bromide (TB)+pulmonary rehabilitation (PR) in chronic obstructive pulmonary disease (COPD) of stage II-III complicated with chronic respiratory failure (CRF).

Material And Methods: Efficacy of therapy was compared in two groups of patients: group 1 (n = 22) received TB in a dose 18 mcg/day for one year, almitrine in a dose 10 mg/kg/day for 3 months, an 8 week course of PR, group 2 (n = 17) received TB and PR. The treatment efficacy was determined by spirometric parameters of external respiration function, blood gases, dyspnea indices, exercise tolerance assessed by 6-min walk test, quality of life (St.
