Recontruction

OBJECTIVE: To observe the cellular morphological and histological changes of the reconstructed tongue defect by rectus abdominis musculoperitoneal flap of dogs with or without nerve. METHODS: 12 Beagle dogs were randomly divided into two groups. Group A made rectus abdominis musculoperitoneal flap with the intercostal nerve while group B without the intercostal nerve. Nerve anastomosis was performed in Group A while not in Group B in the repairment. 12 weeks later, the length, width, surface area and cellular morphology and histological changes of the two transfer flaps were observed...

Images of the levator hiatus in 40 nulliparous, 40 asymptomatic parous women and 40 women with pelvic organ prolapse were obtained by transperineal/translabial three-dimentional ultrasonography of the pelvic floor. Volumes were taken at rest and during squeezing. Recontructed images of the levator hiatus at the plane of minimal dimentions were obtained by off-line processing of the stored volumes. The transverse, the longitudinal diameter and the area of the levator hiatus were measured at rest and during squeezing in the three groups...

OBJECTIVES: There is still a dilemma about best treatment option for patients with severe carotid and coronary artery disease. Reviving of beating heart revascularization technique and using of carotid stenting makes things even more difficult. Discussion about this subject is getting more and more profound. This is analysis of our initial experience with simultaneous carotid and off pump coronary procedures. MATERIALS AND METHODS: This is retrospective analysis of 18 patients operated using this technique in a period from 2001-2003 yrs...

BACKGROUND/AIM: Endovascular treatment of thoracic aortic diseases is an adequate alternative to open surgery. This method was firstly performed in Serbia in 2004, while routine usage started in 2007. Aim of this study was to analyse initial experience in endovacular treatment of thoracic aortic diseses of three main vascular hospitals in Belgrade - Clinic for Vascular and Endovascular Surgery of the Clinical Center of Serbia, Clinic for Vascular Surgery of the Military Medical Academy, and Clinic for Vascular Surgery of the Institute for Cardiovascular Diseases "Dedinje"...

METHODS: Between January 2008 and October 2010, 6 cases of postburn popliteal fossa contractures were recontructed using popliteal fossa middle artery pedicled flaps. Of them, 2 were boys and 4 were girls, aged from 2 years and 2 months to 10 years...

A widening spectrum of increasingly advanced bronchoscopic techniques is available for the diagnosis and treatment of various bronchopulmonary diseases. The evolution of computed tomography (CT)-multidetector CT in particular-has paralleled these advances. The resulting development of two-dimensional and three-dimensional (3D) postprocessing techniques has complemented axial CT interpretation in providing more anatomically familiar information to the pulmonologist. Two-dimensional techniques such as multiplanar recontructions and 3D techniques such as virtual bronchoscopy can provide accurate guidance for increasing yield in transbronchial needle aspiration and transbronchial biopsy of mediastinal and hilar lymph nodes...

UNLABELLED: It is presumed that bilateral mastectomy is so far the most efficient way how to prevent development of breast carcinoma among BRCA positive patients. This mutilating intervention might be unacceptable for cosmetic reasons for most women. The purpose of this study was to determine the influence of prophylactic mastectomy on the quality of life of BRCA positive patients by comparing results of psychodiagnostic questionnaire methods before surgical intervention and after it...

AIM: Zirconia is a ceramic material with optimal aesthetic and mechanical properties that make it adapt to esthetic recontructions in narrow spaces. Aim of this split mouth clinical trial is to compare amount and structure of early plaque coated to zirconia and feldspathic ceramic. METHODS: Four patients were included in this study. A removable acrylic device was manufactured for each subject and equipped on the lingual surface in correspondence to molar teeth with eight specimens...

INTRODUCTION: Radical cystectomy is the most effective treatment madality for high grade urinary bladder carcinoma and orthotopic reconstruction is the better urinary diversion modality also in women. MATERIAL AND METHODS: From 2002 to 2007 we performed 14 radical cystectomies followed by orthotopic reconstruction in women aged between 47 and 68 years (mean age 56) affected by urinary bladder carcinoma. Our reconstructive technique requires the preparation of two strips of the recti muscles fascia, the sectioning of the bladder neck and, when the uterus is present, hysteroannessiectomy and cystectomy en block leaving intact the lateral and inferior vaginal walls...

BACKGROUND: To summarize the experience of carinal resection and reconstruction about the surgical technique and perioperative management in the treatment of carinal and stem bronchial tumor and central bronchogenic carcinoma. METHODS: Eight cases of carinal and stem bronchial tumor and 27 cases of central bronchogenic carcinoma were included in this group, in which the left atrium was invaded in 5 cases. Types of surgery included carinal resection and reconstruction without pulmonary resection in 5 cases, carinal resection and reconstruction plus right upper lobectomy 18 cases, right carinal pneumonectomy 4 cases, left carinal pneumonectomy 4 cases, and carinal resection and recontruction plus left upper lobectomy 4 cases...

BACKGROUND: The trehalose synthetic pathway is present in bacteria, fungi, plants and invertebrate animals, but is absent in vertebrates. This disaccharide mainly functions as a stress protectant against desiccation, heat, cold and oxidation. Genes involved in trehalose synthesis have been observed in apicomplexan parasites, but little was known about these enzymes. Study on trehalose synthesis in apicomplexans would not only shed new light into the evolution of this pathway, but also provide data for exploring this pathway as novel drug target...

BACKGROUND: In cholesteatoma surgery the use of autogenous ossicles for restoration of sound conduction is often limited because of ingrowth of matrix epithelia into the ossicular bone. In an attempt to eliminated these epithelial cells we tested extracorporal high-pressure hydrostatic treatment as a new method for devitalizing the bone but maintaining its structure. METHODS: The inpact of different high hydrostatic pressures either on single cell suspensions of fibroblasts and osteoblasts, or on cells in ex-vivo ossicles chain was examined with different methods (quantitative proceedings, live/dead assay)...

This paper is a retrospective study on 8 patients admitted and treated in Paediatric Surgery and Orthopaedics Clinic of "M. S. Curie" Hospital Bucharest between 1997 and 2007. The patients with malignant bone tumors (table 1.) were studied by sex, tumor type, location, age at the moment of diagnosis, age at the moment of the last evaluation, type of surgery, external fixator implanted, complications, results and survival period. We also considered for each patient the extent of the tumor to diaphysis, soft tissue involvement, involvement of physis and epiphyseal invasion, articular extent, vessels and nerves invasion, presence of metastases and local skin invasion...

Whole genome duplications (WGDs) have been hypothesized to be responsible for major transitions in evolution. However, the effects of WGD and subsequent gene loss on cellular behavior and metabolism are still poorly understood. Here we develop a genome scale evolutionary model to study the dynamics of gene loss and metabolic adaptation after WGD. Using the metabolic network of Saccharomyces cerevisiae as an example, we primarily study the outcome of WGD on yeast as it currently is. However, similar results were obtained using a recontructed hypothetical metabolic network of the pre-WGD ancestor...

OBJECTIVE: To investigate the effect of treatment methods of non-operation and surgical operation for scapular fracture. METHODS: A retrospective analysis of 52 patients (male 37, female 15, ranging in age from 20 to 48 years, meanly 31 years)with scapular fractures was done. According to Hardegger classification: the scapular body fracture in 24 cases, the surgical neck fracture in 12 cases, the anatomical neck fracture in 3 cases, the glenoidal lip fracture in 6 cases, the scapular spine fracrure in 7 cases...

Understanding the basic neuronal building blocks of the neocortex is a necessary first step toward comprehending the composition of cortical circuits. Neocortical layer VI is the most morphologically diverse layer and plays a pivotal role in gating information to the cortex via its feedback connection to the thalamus and other ipsilateral and callosal corticocortical connections. The heterogeneity of function within this layer is presumably linked to its varied morphological composition. However, so far, very few studies have attempted to define cell classes in this layer using unbiased quantitative methodologies...

The prolapse is the exteriorization of the pelvic organs through the vagina, this condition may affect the quality of life. The prolapse was diagnosed in 50% of multiparous women. It is estimated that a woman throughout her life, has 11% risk of needing surgery for correction of pelvic organ prolapse or urinary incontinence. The prolapse may occur at the anterior vaginal wall (cystocele) at the vaginal, uterus (histerocele) or at the posterior wall (or rectocele enterocele). For the unfit patient obliteratives procedures may be indicated and recontructives for pacients wih good performance status...

BACKGROUND: Severe subglottic stenosis is a difficult condition to manage. It can be treated by laryngotracheal reconstruction or cricotracheal resection. PATIENTS AND METHODS: In this retrospective study the experiences for treatment of isolated subglottic stenosis in 37 patients (age: 3-78 years; stenosis grading: 20 x grade II, 13 x grade III, and 4 x grade IV) by laryngotracheal reconstruction in a 30-years experience are presented. RESULTS: In 33 out of 37 patients (89...

BACKGROUND: Many studies have evaluated the use of grafts in the reconstruction of abdominal wall defects. In this study, the effects resulting from the presence or absence of the omentum were evaluated in the setting of infection or serosal defects in the formation of adhesions in abdominal closures using mesh grafts. METHODS: For this study, 60 Wistar albino rats were divided into six groups. A circular 3.79-cm(2) fascioperitoneal defect was created. After group-specific procedures, defects were reconstructed using polypropylene mesh grafts...

We report a case of esophageal perforation caused by an explosion, but which was not diagnosed until 3 days after the injury. A 53-year-old worker sustained superficial dermal burns to his trachea, face, neck, and legs during an explosion. The burns were treated conservatively at a local hospital, but he was transferred to our hospital 3 days after the injury, when mediastinal emphysema and bilateral pleural effusion became evident. An esophagogram followed by computed tomography showed an esophageal perforation caused by the blast injury, and we performed an esophagectomy with recontruction of the gastric tube...
