Cynthia Nau Cornelissen
The pathogenic Neisseria species, including Neisseria meningitidis and Neisseria gonorrhoeae, are obligate human pathogens that cause significant morbidity and mortality. The success of these pathogens, with regard to causing disease in humans, is inextricably linked to their ability to acquire necessary nutrients in the hostile environment of the host. Humans deploy a significant arsenal of weaponry to defend against bacterial pathogens, not least of which are the metal sequestering proteins that entrap and withhold transition metals, including iron, zinc and manganese, from invaders...

Background: Refining the selection of metastatic colorectal cancer (mCRC) patients candidates for anti-EGFR monoclonal antibodies beyond RAS and BRAF testing is a challenge of precision oncology. Several uncommon genomic mechanisms of primary resistance, leading to activation of tyrosine kinase receptors other than EGFR or downstream signaling pathways, have been suggested by preclinical and retrospective studies. Patients and methods: We conducted this multicenter, prospective, case-control study to demonstrate the negative predictive impact of a panel of rare genomic alterations (PRESSING panel), including HER2/MET amplifications, ALK/ROS1/NTRK1-3/RET fusions, and HER2/PI3K/PTEN/AKT1 mutations...

BACKGROUND: Esthesioneuroblastomas (ENB) are uncommon and data regarding outcomes are often limited to single-institution series. The National Cancer Database (NCDB), which contains outcomes information from treatment centers across the United States, represents an opportunity to evaluate outcomes for rare diseases such as ENB across multiple institutions. METHODS: The NCDB was queried for location codes corresponding to the nasal cavity and paranasal sinuses and the histology code for ENB...

Early Post-Operative Fever after cochlear Implant surgery is not uncommon. We assessed all pediatric patients undergoing cochlear implants and addressed the patients with post-operative fever. A hundred and thirty surgeries were performed; of all patients 25 developed early postoperative fever. The workup did not identify the cause of fever in any of the patients. Fever resolved without any additional Intervention. There was no difference in fever or infection rate in patients that received prophylactic antibiotic, whether prolonged (one week) versus or only perioperative treatment (one day)...

Choking in adults can prove fatal, despite resuscitation attempts. The manner of death can be natural, homicide or accident. When a death is due to choking, one must consider what conditions contributed to or predisposed the person to choking (eg. alcohol, drugs and physical and mental impairments). Homicidal deaths by choking are relatively uncommon, being more frequently accidental. The diagnosis of death by choking is made at autopsy when the airway is found occluded. If the individual had an occluded airway and the object or food was removed during resuscitation, the only way to make the diagnosis would be on the history...

Isolated enophthalmos is a rarely observed entity in neurofibromatosis (NF). A 12-year-old male presented with right lower eyelid fat prolapse and enophthalmos for the past 7 years. There was no history of antecedent trauma/surgery. Computed tomography of orbit revealed an ill-defined intraconal hyperdense lesion located between lateral and inferior rectus along with an enlarged inferior orbital fissure (IOF). Superior orbital fissure was minimally widened without prolapse of any intracranial contents. Excision biopsy along with repair of widened IOF was performed through inferior transconjunctival route...

HLA-matched hematopoietic stem cell transplantation (HSCT) from red blood cell (RBC)-incompatible donors is not uncommon. The engraftment process following ABO-incompatible allogeneic HSCT results in the transition from patient blood group to donor blood group in the recipient. In contrast, most non-hematopoietic tissues retain expression of the patient's original blood group for life, and these antigens may adsorb from the plasma onto the donor-derived RBCs. Correct serologic interpretation of the ABO blood group during this engraftment process can be difficult...

Endometriosis is defined by the presence of ectopic endometrial tissue outside the uterine cavity. Although it is a leading cause of chronic pelvic pain and infertility, its clinical presentation can vary, resulting in diagnostic and therapeutic challenges. Extrapelvic endometriosis is particularly difficult to diagnose owing to its ability to mimic other conditions. Endometrial tissue in a surgical scar is uncommon and often misdiagnosed as a granuloma, abscess, or malignancy. Cyclical hemorrhagic ascites due to peritoneal endometriosis is exceptionally rare...

Primary Sjögren's syndrome (pSS) is characterized by lymphocytic infiltration of the exocrine glands resulting in decreased saliva and tear production. It uncommonly involves the kidneys in various forms, including tubulointerstitial nephritis, renal tubular acidosis, Fanconi syndrome, and rarely glomerulonephritis. Its clinical symptoms include muscle weakness, periodic paralysis, and bone pain due to metabolic acidosis and electrolyte imbalance. Herein, we describe the cases of two women with pSS whose presenting symptoms involve the kidneys...

Mesenchymal neoplasms of salivary gland including adipocytes are relatively uncommon entity classified as monophasic and biphasic. Sialolipoma, a biphasic mesenchymal salivary gland neoplasm, with a prominent vascularity designated as sialoangiolipoma (SAL) is a recently discussed entity with debates on the hamartomatous nature of the lesion. We have endorsed the hamartomatous nature through evaluating the immunoexpression of Ki-67 and endoglin in SAL in hard palate of a 60-year-old patient. To the best of our knowledge, this would be the second case of SAL in hard palate in a global platform...

The everyday practice of dentistry relies heavily on achieving adequate local anesthesia. Even though the safety record of local anesthetic agents is high, complications do occur. Palate is a favorable site for soft-tissue lesions. Various factors such as direct effects of the drug, blanching of the tissues during injection, relatively poor blood supply, and reactivation of the latent forms of herpes can all promote to tissue ischemia and a lesion in the palate. Among various complications, anesthetic necrotic ulcer is a rare and uncommon condition occurring mostly in the hard palate possibly after a local anesthetic infiltration...

Exercise induced complete atrioventricular block (EIAVB) is a relatively uncommon condition. This phenomenon is clinically important because it can mimic symptoms of other cardiovascular conditions and may be associated with exercise intolerance and subsequent syncope. A 76year old man with long-standing hypertension and diabetes mellitus presented with recurrent episodes of lightheadedness and syncope with physical activity. ECG showed sinus rhythm with first degree atrioventricular block. Echocardiography did not show any valvular disease causing his symptoms...

In this work, a novel and simple optical fiber hot-wire anemometer based on single-walled carbon nanotubes (SWCNTs) coated tilted fiber Bragg grating (TFBG) is proposed and demonstrated. For the hot-wire wind speed sensor design, TFBG is an ideal in-fiber sensing structure due to its unique features. It is utilized as both light coupling and temperature sensing element without using any geometry-modified or uncommon fiber, which simplifies the sensor structure. To further enhance the thermal conversion capability, SWCNTs are coated on the surface of the TFBG instead of traditional metallic materials, which have excellent thermal characteristics...

We report a case of a patient with esophageal tuberculosis, a very uncommon form of extrapulrhonar tuberculosis. Initially, because of constitutional symptomatology and radiological findings of mediastinal lymph node enlargement, lymphoma was considered. However, the endoscopic findings of ulcerative masses and a sinus tract revealed by esophagram were suspicious of tuberculous origin. Diagnosis was achieved after bacterial examination of smear samples from esophageal ulcers that revealed bacillus tuberculous and histological demonstration of caseating granulomas in cervical lymph nodes...

Background: By eliminating a thoracotomy, transhiatal esophagectomy (THE) is purported to reduce postoperative pulmonary complications. However, data from many early series do not support this contention, documenting pulmonary complications in up to 50% of patients and pneumonia in 5%-20%. Since 1990, we have implemented a management strategy designed to maximize airway protection in the postoperative period. The purpose of this study was to determine the current incidence of pulmonary complications after transhiatal esophagectomy without thoracotomy...
