Investigation into Breast Cancer and Partial Breast Reconstruction: A Review

Growing increasingly in South America, Africa and Asia, breast cancer is known as the dominant type of cancer in women. Different treatments are available for breast cancer, among which surgery is the most widely used, but researchers are trying to develop new strategies. One of the most prominent surgical methods is referred to as oncoplastic surgery, that helps to remove segments of malignant breast tissue. This type of surgery aims to obtain vast surgical margins, while the remaining tissue is rearranged so that the better cosmetic outcome is obtained. This review will investigate the breast cancer and then discuss partial breast reconstruction. Before outlining the procedures, the different types of partial breast reconstruction will be discussed. Finally, advantages and disadvantages will be outlined. MEDLINE database was used to conduct the search. The main terms used were ‘Conservation Breast Surgery Reconstruction’ AND ‘Oncoplastic Surgery’, ‘Partial Mastectomy Reconstruction’ AND ‘Conservative Breast Surgery Reconstruction’, ‘oncoplastic’ [All Fields], ‘breast’ AND ‘surgery’ OR ‘surgery’ operative’, ‘oncoplastic’ (‘breast’)’. The bibliographies of relevant papers were manually searched up to October 2018, but more recent voices are also included

Cyclometalated platinum(II) complexes of 2,2'-bipyridine N-oxide containing 1,1'-bis(diphenylphosphino)ferrocene ligand: Structural, computational and electrochemical studies

The preparation and characterization of new heteronuclear-platinum(II) complexes containing 1,1'-bis(diphenylphosphino)ferrocene (dppf) ligand are described. The reaction of the known starting complex [PtMe(κ2N,C-bipyO-H)(SMe2)], A, in which bipyO-H is a cyclometalated “rollover” 2,2'-bipyridine N-oxide, with the dppf ligand in a 2 : 1 ratio or an equimolar ratio led to the formation of corresponding binuclear complex [Pt2Me2(κ2N,C-bipyO-H)2(µ-dppf)], 1, or mononuclear complex [PtMe(κ1C-bipyO-H)(dppf)], 2, respectively. According to the reaction conditions, the dppf ligand in 1 and 2 behaves as either a bridging or chelateing ligand. All complexes were characterized by NMR spectroscopy. The solid-state structure of 2 was determined by single-crystal X-ray diffraction method and it was shown that the chelateing dppf ligand in this complex was arranged “synclinal-staggered” conformation. Also, the occurrence of intermolecular C–HCp…ObipyO-H interactions in the solid-state gave rise to an extended 1-D network. The electronic absorption spectra and the electrochemical behavior of these complexes are discussed. Density functional theory (DFT) was used for geometry optimization of the singlet states in solution and for electronic structure calculations. The analysis of the molecular orbital (MO) compositions in terms of occupied and unoccupied fragment orbitals in 2 was performed

Creatinine Phosphokinase (CPK) Elevation in the Coexistence of Wilson's Disease and Autoimmune Hepatitis with Atypical Presentation: A Diagnostic Dilemma

Background: Wilson's disease (WD) is a genetic disorder with various clinical presentations due to excessive accumulation of copper in the liver and other organs. It can present as acute/chronic hepatitis, liver failure, extrahepatic and neuromuscular manifestations. Autoimmune hepatitis (AIH) is a necroinflammatory disease of the liver, which affects a lot of people particularly the children population. AIH has a broad clinical presentation that is similar to WD. Coexistence of WD with elevated creatinine phosphokinase (CPK) and AIH, may be a diagnostic dilemma. Case Report: We presented a 6 years old boy with dysarthria, aggressive behavior, weak attention, concentration and weight loss with abnormal physical examination. Laboratory, histochemical, genomic studies, muscle/liver biopsy and atomic absorption test confirmed the diagnosis of both WD and AIH in the boy. Conclusion Although CPK and liver enzyme elevation is a rare presentation of chronic hepatitis with dominant feature of WD and AIH; however, simultaneous therapy with immunosuppressive drugs and Penicillamine may have superior benefit with a significant response

Ciliated Hepatic Foregut Cyst: Two Case Reports in Children and Review of the Literature

Ciliated hepatic foregut cyst (CHFC) is a rare lesion which originates from detached hepatic diverticulum or from detachment and migration of buds from the esophageal and bronchial regions of the foregut which subsequently get entrapped by the liver during the early embryonic development of the foregut. CHFCs are mostly seen in adults and are rarely reported in children, with only about 10 cases reported in this age group. Hereby, we present two cases of CHFC in two 3.5-year-old boys; one of them had cystic lesion at medial segment of left lobe of liver (common site), and in the other one it was located at right lobe of liver (less common site). Histologically, both cysts had four layers composed of inner ciliated, pseudostratified, columnar epithelium; subepithelial connective tissue; smooth muscle layer; and an outer fibrous layer

Sporadic Insulinoma as a Rare Cause of Recurrent Hypoglycemia in Children

Insulinoma is a rare pancreatic tumor in children and adolescents. As a result of insulin hypersecretion, signs and symptoms are more commonly consequences of the pathophysiologic responses to hypoglycemia. According to rarity of this tumor in children and nonspecificity of clinical presentations, diagnosis of insulinoma in this group of patients is usually delayed. Early diagnosis is very important for preventing neurologic damage. In this case report, we present the case of a 10-year-old boy with signs and symptoms of hypoglycemia and final diagnosis of insulinoma

Primary Intrarenal Neuroblastoma with Hypertension and Disseminated Intravascular Coagulation

The primary intrarenal neuroblastoma (IRNB) is a rare condition. Intrarenal neuroblastoma typically results from direct renal invasion from an adrenal neuroblastoma, but true intrarenal neuroblastoma originates either sequestered adrenal rests during the fetal life or intrarenal sympathetic ganglia. Clinical, radiological, and pathological correlation is very essential for diagnosis and appropriate management of this type of unusual cases. The distinction of this rare tumor from Wilms’ tumor is an important challenge since both tumors have major differences in prognostic and therapeutic response. We present a 3-year-old boy of primary intrarenal neuroblastoma with extensive abdominal and mediastinal mass, persistent hypertension, and disseminated intravascular coagulation (DIC)

The Effects of Fifa 2015 Computer Games on Changes in Cognitive, Hormonal and Brain Waves Functions of Young Men Volunteers

Introduction: Computer games have attracted remarkable attentions in general publics with different cultures and their effects are subject of research by cognitive neuroscientists. In the present study, possible effects of the game Fifa 2015 on cognitive performance, hormonal levels, and electroencephalographic (EEG) signals were evaluated in young male volunteers. Methods: Thirty two subjects aged 20 years on average participated mutually in playing computer game Fifa 2015. Identification information and general knowledge about the game were collected. Saliva samples from the contestants were obtained before and after the competition. Perceptive and cognitive performance including the general cognitive health, response delay, attention maintenance, and mental fatigue were measured using PASAT test. EEG were recorded during the play using EEG device and analyzed later using QEEG. Simultaneously, the players’ behavior were recorded using a video camera. Saliva cortisol levels were assessed by ELISA kit. Data were analyzed by SPSS program. Results: The impact of playing computer games on cortisol concentration of saliva before and after the game showed that the amount of saliva plasma after playing the game has dropped significantly. Also the impact of playing computer games on mental health, before and after the game indicated that the number of correct answers has not changed significantly. This indicates that sustained attention has increased in participants after the game in comparison with before that. Also it is shown that mental fatigue measured by PASAT test, did not changed significantly after the game in comparison to before that. The impact of game on changes in brain waves showed that the subjects in high activity state during playing the game had higher power of the EEG signals in most of the channels in lower frequency bands in compared to normal state. Discussion: The present study showed that computer games can positively affect the stress system and the perceptual-cognitive system. Even though this impact was not significant in most cases, the changes in cognitive and hormonal test and also in brain waves were visible. Hence, due to the importance of this matter, it is necessary to create control systems in selecting the types of games for playing

Very early onset inflammatory bowel disease: Investigation of the IL-10 signaling pathway in Iranian children

Background & aim: Comparing to adult inflammatory bowel disease (IBD), those with early onset manifestations have different features in terms of the underlying molecular pathology, the course of disease and the response to therapy. We investigated the IL-10 signaling pathway previously reported as an important cause of infantile (Very Early Onset) IBD to find any possible variants. Method: With the next generation sequencing technique we screened IL-10, IL-10RA and IL10RB genes of 15 children affected by very early onset-GI (gastrointestinal) disorders. Additionally, we analyzed them based on Thermo Fisher immune deficiency panel for genes either having a known role in IBD pathogenesis or cause the disorders with overlapping manifestations. We performed multiple functional analyses only for the cases showing variants in IL-10-related genes. Result: In 3 out of 15 patients we identified variants including a homozygous and heterozygote mutations in IL-10RA and a novel homozygous mutation in IL-12RB1. Our functional studies reveal that in contrast to the IL-10RA heterozygote mutation that does not have deleterious effects, the homozygous mutation abrogates the IL-10 signaling pathway. Conclusion: Our study suggests we need to modify the classical diagnostic approach from functional assays followed by candidate-gene or genes sequencing to the firstly parallel genomic screening followed by functional studies.
