Achalasia with megaesophagus and tracheal compression in a young patient: A case report.

2015

Highlights • This report emphasizes that physicians should be alert and consider airway obstruction and signs of dyspnea as severe and threatening symptoms in extensive cases of achalasia with megaesophagus. • Early surgical treatment provides a therapeutic option to obviate the occurrence of acute respiratory distress and consecutive complications. • In particular, difficulties in intubation prior to surgery must be considered. Due to potential tracheomalacia, the status of “bull frog neck” in achalasia, including severe tracheal compression caused by megaesophagus with concomitant cervical swelling, may also lead to extubation problems and deserves special care in the postoperative period.

American College of Cardiology/ European Society of Cardiology international study of angiographic data compression phase III. Measurement of image q…

2000

Objectives We sought to investigate up to which level of Joint Photographic Experts Group (JPEG) data compression the perceived image quality and the detection of diagnostic features remain equivalent to the quality and detectability found in uncompressed coronary angiograms. Background Digital coronary angiograms represent an enormous amount of data and therefore require costly computerized communication and archiving systems. Earlier studies on the viability of medical image compression were not fully conclusive. Methods Twenty-one raters evaluated sets of 91 cine runs. Uncompressed and compressed versions of the images were presented side by side on one monitor, and image quality differe…

Effects of training on postural control and agility when wearing socks of different compression levels

2017

Summary Study aim: The aim of this study was to evaluate the effects of training while wearing socks differing in compression level (clinical, sub-clinical, regular) on performance of static and dynamic balancing and agility tasks in healthy, physically active people. We sought to understand whether socks with different compression properties supported postural regulation and agility task performance by enhancing somatosensory perception, unskewed by specific age range effects. Material and methods: Participants comprised 61 adults aged 18-75 years, divided into three groups (two experimental groups wearing clinical or sub-clinical level compression socks, and one control group wearing regu…

Dolichoectasia of the vertebrobasilar complex causing neural compression

2014

Dear Editor, We have read with great interest the paper of Yuh et al.[4] reporting a case of symptomatic hydrocephalus due to vertebrobasilar dolichoectasia (VBD) compressing the brainstem. Ectatic or pathologically enlarged vertebrobasilar arteries have been reported with increasing frequency and associated with several clinical syndromes. These include an assortment of cranial nerve syndromes, transient or permanent motor deficit, cerebellar dysfunction, central sleep apnea, ischemic stroke, hypertension, and hydrocephalus as reported in the paper by Yuh et al.[4] Others and we have also described pyramidal tract signs and cranial nerve nucleus dysfunction caused by vascular compression o…

Discordancia clínico-radiológica y resolución espontánea de un hematoma postcateterización epidural

2008

Neuraxial techniques are considered safe if certain guidelines are followed, but they are not risk free. We report the case of an 81-year-old woman with an invasive bladder tumor who underwent radical cystectomy with a Bricker-type procedure. General anesthesia was used and epidural analgesia was also provided for surgical and postoperative pain management. Late in the postoperative recovery period a large epidural hematoma was diagnosed based on radiologic signs of spinal cord compression, in the absence of symptoms other than mild and progressive back pain that developed after extubation. The surgeon decided against emergency surgery to reduce compression. Symptoms resolved gradually, and…

Unusual recurrence of trigeminal neuralgia after microvascular decompression by muscle interposal.

2011

Summary Background Patients with trigeminal neuralgia (TN) and persistent or recurrent facial pain after microvascular decompression (MVD) typically undergo less invasive procedures in the hope of providing pain relief. However, re-operation should be considered in selected patients. Case Report A 48-year-old woman presented with recurrent trigeminal neuralgia (TN) 3 years following microvascular decompression (MVD). The patient underwent brain magnetic resonance angiography (MRA), which did not reveal neurovascular compression; therefore surgical re-exploration was carried out. During the operation, the fifth cranial nerve was seen without impingement from any blood vessels; however, a ver…

European guidelines on chronic mesenteric ischaemia - joint United European Gastroenterology, European Association for Gastroenterology, Endoscopy an…

2020

Chronic mesenteric ischaemia is a severe and incapacitating disease, causing complaints of post-prandial pain, fear of eating and weight loss. Even though chronic mesenteric ischaemia may progress to acute mesenteric ischaemia, chronic mesenteric ischaemia remains an underappreciated and undertreated disease entity. Probable explanations are the lack of knowledge and awareness among physicians and the lack of a gold standard diagnostic test. The underappreciation of this disease results in diagnostic delays, underdiagnosis and undertreating of patients with chronic mesenteric ischaemia, potentially resulting in fatal acute mesenteric ischaemia. This guideline provides a comprehensive overvi…

Microencapsulation of Salmonella-Specific Bacteriophage Felix O1 Using Spray-Drying in a pH-Responsive Formulation and Direct Compression Tableting o…

2019

The treatment of enteric bacterial infections using oral bacteriophage therapy can be challenging since the harsh acidic stomach environment renders phages inactive during transit through the gastrointestinal tract. Solid oral dosage forms allowing site-specific gastrointestinal delivery of high doses of phages, e.g., using a pH or enzymatic trigger, would be a game changer for the nascent industry trying to demonstrate the efficacy of phages, including engineered phages for gut microbiome modulation in expensive clinical trials. Spray-drying is a scalable, low-cost process for producing pharmaceutical agents in dry powder form. Encapsulation of a model Salmonella-specific phage (Myoviridae…
