Cigdem Altan, Berna Basarir, Cem Kesim
A 47-year-old male presented with bilateral 4 + circulating pigment in the anterior chamber, diffuse iris transillumination, dilated pupils unresponsive to light, and high intraocular pressure (IOP) levels in both eyes. Visual acuity and IOP improved bilaterally with topical steroid and antiglaucomatous therapy. In the 10th month, bilateral cystoid macular edema (CME) was developed and resolved after subtenon triamcinolone injections. CME recurred after cataract surgery in the right eye which was treated with intravitreal dexamethasone implant injection...

PURPOSE: Arthroscopic lysis and lavage surgery (AS) is an effective modality that can decrease pain and increase maximum interincisal opening (MIO) in patients with internal derangement (ID) of the temporomandibular joint (TMJ). However, some patients remain in pain or have limited mandibular range of motion despite AS. The purpose of this study was to determine the effectiveness, prevalence of adverse effects, and predictors of response to TMJ AS in patients with TMJ arthralgia and ID...

Delayed hippocampal injury and memory impairments follow neonatal hypoxia-ischemia (HI) despite the use of therapeutic hypothermia (TH). Death of hippocampal pyramidal cells occurs acutely after HI, but characterization of delayed cell death and injury of interneurons (INs) is unknown. We hypothesize that injury of INs after HI is: i) asynchronous to that of pyramidal cells, ii) independent of injury severity, and iii) unresponsive to TH. HI was induced in C57BL6 mice at p10 with unilateral right carotid ligation and 45 min of hypoxia (FiO2 =0...

A 12-year-old, female, domestic cat (Felis catus) presented with dehydration, emaciation, anorexia, and lethargy. The cat was unresponsive to medical treatment and euthanized; the carcass was submitted for pathological diagnosis. Necropsy revealed icteric mucous membranes. The liver was enlarged, with multinodular, cystic, white masses, 0.5-4.0 cm in diameter, scattered throughout. Microscopically, the biliary epithelium presented with a proliferation of multifocal cystic masses, occasionally with periodic acid-Schiff-positive fluid within the cysts...

BACKGROUND: Epicutaneous immunotherapy (EPIT) is a promising method for treating food allergies. In animal models, EPIT induces sustained unresponsiveness and prevents further sensitization mediated by Tregs. Here, we elucidate the mechanisms underlying the therapeutic effect of EPIT, by characterizing the kinetics of DNA methylation changes in sorted cells from spleen and blood and by evaluating its persistence and bystander effect compared to oral immunotherapy (OIT). METHODS: BALB/c mice orally sensitized to peanut proteins (PPE) were treated by EPIT using a PPE-patch or by PPE-OIT...

INTRODUCTION: Radical cystectomy and extended pelvic lymph node dissection (ePLND) are the gold standard treatment for muscle-invasive bladder cancer and BCG unresponsive nonmuscle-invasive bladder cancer. In this article, we review the rationale for ePLND in the treatment of bladder cancer and the evidence supporting the equipoise between robot-assisted (RA) and open ePLND. A step-by-step guide of robot-assisted ePLND (RA ePLND) is provided to illustrate the techniques currently employed at our institution...

The standard of care for chronic deep peri-prosthetic hip infection is a two-stage exchange with placement of a temporary antibiotic cement spacer and treatment with intravenous antibiotics. Several commercially available cement spacer options exist. We report on a novel antibiotic spacer that may be an efficient, cost-effective alternative. Medical records of all patients treated for deep peri-prosthetic hip infection after total hip arthroplasty between 2004 and 2012 were reviewed. Each antibiotic spacer was constructed from a 12- to 16-hole recon plate bent to provide adequate soft tissue tension and a cement ball that matched the acetabulum...

Falk A Gonnert, Winfried Meißner
Metamizole is primarily used for severe perioperative pain, acute injury and colic, and cancer pain. For other acute/chronic forms of pain and high fever, it should only be used if unresponsive to other agents. Metamizole should not be used for middle and low pain. Oral application should be preferred. A contraindication for metamizole is leukopenia. Clinical signs for agranulocytosis are fever, tonsillitis and aphthous stomatitis.

Carbon monoxide (CO) is the cause of a significant percentage of fatal poisonings in many countries. It is known that fatalities resulting from CO poisoning are underreported and/or misclassified. Carbon monoxide exposure while driving can occur due to faulty exhaust systems, defective ventilation systems, emission from other vehicles, and even cigarette smoking. We report the case of a 23-year-old woman who was involved in a low-speed motor vehicle collision and was found unresponsive in her vehicle due to CO poisoning...

REVIEW
Matthias J Müller, Thomas Paul
Syncope is common in children and adolescents. Neurally mediated syncope including pallid and cyanotic breath holding spells, vagovasal syncope and neurocardiogenic syncope is based on a common pathomechanism and accounts for approximately 75% of cases. A potentially life-threatening cardiac cause of syncope may be present in up to 6%. Detailed history, physical examination and 12-lead electrocardiogram (ECG) allow discrimination between benign and serious syncope in the majority of pediatric patients. Tilt-testing can be useful when diagnosis is unclear...

B-cell lymphoma 2-related protein A1 (BCL2A1) is a member of the BCL-2 family of anti-apoptotic proteins that confers resistance to treatment with anti-cancer drugs; however, there are presently no agents that target BCL2A1. The MUC1-C oncoprotein is aberrantly expressed in triple-negative breast cancer (TNBC) cells, induces the epithelial-mesenchymal transition (EMT) and promotes anti-cancer drug resistance. The present study demonstrates that targeting MUC1-C genetically and pharmacologically in TNBC cells results in the downregulation of BCL2A1 expression...

Autoimmunity develops when self-tolerance mechanisms are failing to protect healthy tissue. A sustained reaction to self is generated, which includes the generation of effector cells and molecules that destroy tissues. A way to restore this intrinsic tolerance is through immune modulation that aims at refurbishing this immunologically naïve or unresponsive state, thereby decreasing the aberrant immune reaction taking place. One major cytokine has been shown to play a pivotal role in several autoimmune diseases such as rheumatoid arthritis (RA) and multiple sclerosis (MS): tumor necrosis factor alpha (TNFα) modulates the induction and maintenance of an inflammatory process and it comes in two variants, soluble TNF (solTNF) and transmembrane bound TNF (tmTNF)...

Lymphangioleiomyomatosis (LAM) is a rare, almost exclusively female lung disease linked to inactivating mutations in tuberous sclerosis complex 2 (TSC2), a tumor suppressor gene that controls cell metabolic state and growth via regulation of the mechanistic target of rapamycin (mTORC1) signaling. mTORC1 is frequently activated in human cancers and, although the mTORC1 inhibitor rapamycin has a cytostatic effect, it is, in general, unable to elicit a robust curative effect or tumor regression. Using RNA-Seq, we identified (1) Insulin-like Growth Factor (IGF2) as one of the genes with the highest fold-change difference between human TSC2-null and TSC2-expressing angiomyolipoma cells from a patient with LAM, and (2) the mouse IGF2 homolog Igf2, as a top-ranking gene according to fold change between Tsc2-/- and Tsc2+/+ mouse embryo fibroblasts (MEFs)...

Intradural spinal cord abscesses are rare infections in early childhood and usually result from pre-existing congenital anomalies of the spinal column. The formation of abscess may be the result of hematogenous spread. It is treated by surgical and parenteral antibiotic treatment, but some special cases may require additional treatments. This article presents a 4-year-old male patient who was operated because of spina bifida (meningocele and tethered cord) at the external center, and upon complains of not being able to walk after one month, he was operated with the diagnosis of spinal intradural abscess and referred to us to continue his treatment...

PURPOSE OF REVIEW: Congenital hyperinsulinism is the most common cause of persistent hypoglycemia in infants and children. Early and appropriate recognition and treatment of hypoglycemia is vital to minimize neurocognitive impairment. RECENT FINDINGS: There are at least 11 known monogenic forms of hyperinsulinism and several associated syndromes. Molecular diagnosis allows for prediction of the effectiveness of diazoxide and the likelihood of focal hyperinsulinism...

BACKGROUND: Taxanes chemotherapies represent the major therapeutic alternative for symptomatic mCRPC. While docetaxel is the most commonly prescribed Taxane for mCRPC; cabazitaxel has been approved for patients unresponsive to docetaxel. Still mCRPC remains incurable and patients often experience severe side effects. Recently, the FIRSTANA trial first demonstrated the absence of superiority in overall survival between cabazitaxel and docetaxel in mCRPC patients. Inversely, different toxicity were reported suggesting that cabazitaxel may provide a first line treatment option for some patients urging for a deeper characterization of cabazitaxel mechanisms of action as well as a re-evaluation of cabazitaxel conventional dose and schedule...

Approximately 75% of breast cancers are estrogen receptor alpha (ERα)-positive and are treatable with endocrine therapies, but often patients develop lethal resistant disease. Frequent mutations (10-40%) in the ligand-binding domain (LBD) codons in the gene encoding ERα (ESR1) have been identified, resulting in ligand-independent, constitutively active receptors. In addition, ESR1 chromosomal translocations can occur, resulting in fusion proteins that lack the LBD and are entirely unresponsive to all endocrine treatments...
