OBJECTIVE: Non-rechargeable deep brain stimulation (DBS) impulse generators (IG) with a low or empty battery status require surgical IG exchange several years after initial implantation. Complication rates in patients undergoing DBS surgery range from 7.6% to 25.3%. The aim of this study was to investigate the complication rates after IG exchange surgery and to identify risk factors for complications. METHODS: We retrospectively analysed complications following IG exchange surgery from 2008 to 2015 in a single-centre university hospital setting...

Collateral circulation secondary to liver cirrhosis may cause the development of large PSSs that may steal flow from the main portal circulation. It is important to identify these shunts prior to, or during the transplant surgery because they might cause an insufficient portal flow to the implanted graft. There are few reports of "steal flow syndrome" cases in pediatrics, even in biliary atresia patients that may have portal hypoplasia as an associated malformation. We present a 12-month-old female who received an uneventful LDLT from her mother, and the GRWR was 4...

BACKGROUND: After radical cystoprostatectomy (RC), postoperative erectile dysfunction (ED) is a common consequence with multiple contributing etiologies. The inflatable penile prosthesis (IPP) offers patients a definitive treatment option when ED is refractory to medical therapies. Because of the hostile postoperative anatomy of these patients, a careful surgical approach is necessary for successful outcomes and to avoid adjacent organ injury. To date, there is no series describing the outcomes of 3-piece IPP placement in patients with urinary diversions...

Facial nerve anomalies are a potential problem in patients with cochleovestibular malformations. A case of cochlear implant (CI) surgery in the presence of intra-temporalbone facial nerve bifurcation is presented. During the first surgery, the facial nerve bifurcation obscured the promontory and round window. It was difficult to perform cochleostomy because of the lack of landmarks of the basal turn of the cochlea, and the first surgical attempt at cochleostomy was abandoned. A repeat CT scan was performed after the first surgery with reconstructed 3D images of the temporal bone and the cochlea, and then the cochlea was successfully opened at revision surgery...

BACKGROUND: In the treatment of center-involving diabetic macular edema, despite initial therapy with an anti-VEGF compound, an insufficient response may occur. Further therapy options include a switch of anti-VEGF products or to corticosteroid implants, such as Fluocinolone acetonide or Dexamethasone. OBJECTIVES: Firstly, to investigate systematically which evidence-based study data are available describing the efficacy of in-label treatments after primary anti-VEGF treatment, secondly, to investigate which costs go along for the healthcare provider...

BACKGROUND CONTEXT: There is a broad spectrum of complications during or after surgical procedures, with differing incidences reported in the published literature. Heterogeneity can be explained by the lack of an established evidence-based classification system for documentation and classification of complications in a standardized manner. PURPOSE: To identify predictive risk factors for peri- and early post-operative morbidities in spine surgeries of different complexities in a large cohort of consecutive patients...

OBJECTIVE Currently, there is no treatment that slows or halts the progression of Parkinson's disease. Delivery of various neurotrophic factors to restore dopaminergic function has become a focus of study in an effort to fill this unmet need for patients with Parkinson's disease. Schwann cells provide a readily available source of such factors. This study presents a 12-month evaluation of safety and feasibility, as well as the clinical response, of implanting autologous peripheral nerve grafts into the substantia nigra of patients with Parkinson's disease at the time of deep brain stimulation (DBS) surgery...

OBJECTIVE: We illustrate the magnetic resonance imaging (MRI) features of endometriosis. BACKGROUND: Endometriosis is a chronic gynaecological condition affecting women of reproductive age and may cause pelvic pain and infertility. It is characterized by the growth of functional ectopic endometrial glands and stroma outside the uterus and includes three different manifestations: ovarian endometriomas, peritoneal implants, deep pelvic endometriosis. The primary locations are in the pelvis; extrapelvic endometriosis may rarely occur...

INTRODUCTION: Sensory neural hearing loss could lead to some structural and physiological changes in the auditory pathways, such as alteration in the expression of neurotrophins. These factors, especially Brain-Derived Neurotrophic Factor (BDNF), play an important role in synaptic functions and experience-related plasticity. Restoring cochlear function after hearing loss is possible through cochlear implantation (CI). Evaluation of the blood concentration changes of neurotrophins as prerequisites of plasticity could help scientists to determine the prognosis of CI as in the candidacy procedure or enhancing prosthesis function by adding the exact needed amount of BDNF to the electrode array...

BACKGROUND: The CPORT-E trial showed the noninferiority of nonprimary percutaneous coronary intervention (PCI) at hospitals without cardiac surgery on-site (SoS) compared with hospitals with SoS for 6-week mortality and 9-month major adverse cardiac events (MACE). However, target vessel revascularization (TVR) was increased at non-SoS hospitals. Therefore, we aimed to determine the consistency of the CPORT-E trial findings across the spectrum of enrolled patients. METHODS: Post hoc subgroup analyses of 6-week mortality and 9-month MACE, defined as the composite of death, Q-wave myocardial infarction, or TVR, were performed...
