Immediate effects of Zhongji point acupuncture on pelvic floor structure in female patients with stress urinary incontinence: a randomized, single-blind, and sham-controlled clinical trial protocol.

Ann Palliat Med 2021 Jul 2. Epub 2021 Jul 2.

Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine, Shanghai, China.

Background: Stress urinary incontinence (SUI) is defined as involuntary leakage of urine from the external urethra due to increased abdominal pressure, for example, upon sneezing, coughing, or exercise. Acupuncture is an effective therapy for patients with SUI, although objective evidence of its benefits or mechanism of action is limited. Patients with SUI often harbor structural changes of pelvic floor, the parameters of which are measurable from various perspectives and in multiple dimensions, dynamically and comprehensively, through transperineal ultrasound (TPUS).

Rationale and Design of a Panel Study Investigating Six Health Effects of Airborne Pollen: The EPOCHAL Study.

Front Public Health 2021 18;9:689248. Epub 2021 Jun 18.

Swiss Tropical and Public Health Institute, Basel, Switzerland.

While airborne pollen is widely recognized as a seasonal cause of sneezing and itchy eyes, its effects on pulmonary function, cardiovascular health, sleep quality, and cognitive performance are less well-established. It is likely that the public health impact of pollen may increase in the future due to a higher population prevalence of pollen sensitization as well as earlier, longer, and more intense pollen seasons, trends attributed to climate change. The effects of pollen on health outcomes have previously been studied through cross-sectional design or at two time points, namely preceding and within the period of pollen exposure. Read More

Orbital Infection Due to Medial Wall Fracture: Three Cases of Orbital Complications Caused by Paranasal Sinusitis Secondary to Medial Orbital Wall Fracture.

J Craniofac Surg 2021 Jun 23. Epub 2021 Jun 23.

Eye Hospital, Wenzhou Medical University, Wenzhou, Zhejiang Province, China.

Purpose: The aim of this study was to report 3 cases of orbital complications in patients with secondary sinusitis due to medial orbital wall fracture. We believe that sinusitis can be secondary to the fracture of the medial orbital wall when the sinus drainage orifice is blocked due to some fracture pieces or other blocking factors. We precisely show the direct evidence of the blocking factors through radiology. Read More

Comparison of urethral sling surgery and non-ablative vaginal Erbium:YAG laser treatment in 327 patients with stress urinary incontinence: a case-matching analysis.

Lasers Med Sci 2021 Apr 22. Epub 2021 Apr 22.

Fotona d.o.o., Stegne 7, 1000, Ljubljana, EU, Slovenia.

Stress urinary incontinence (SUI) occurs when abdominal pressure, such as from coughing or sneezing, causes urine leakage. We retrospectively compared tension-free vaginal tape (TVT) and non-ablative vaginal Erbium:YAG laser treatment (VEL) by propensity score (PS) analysis in women with SUI. No PS analysis studies have investigated urethral sling surgery using polypropylene TVT and VEL for SUI. Read More

A rare case of spontaneous otogenic pneumocephalus with pictorial illustration of temporal evolution.

J Clin Neurosci 2021 May 20;87:132-136. Epub 2021 Mar 20.

Department of Diagnostic Imaging, National University Hospital, National University Health System, Singapore. Electronic address:

Pneumocephalus is commonly seen on imaging in the setting of craniofacial trauma, skull base tumours, intracranial infection and after neurological intervention. Spontaneous pneumocephalus in the absence of these conditions is exceedingly rare, with only approximately 30 cases reported in the literature to date. Spontaneous otogenic pneumocephalus (SOP) is believed to occur as a result of anomalous communication between the intracranial space and a hyper-pneumatised temporal bone, with either positive extra-to-intracranial pressure or negative intracranial pressure gradient.

Under healthy condition, more than one urethra-closing reflex, including both bladder afferent-independent and -dependent actions function during momentary elevation of intravesical (bladder) pressure to prevent urinary incontinence In the current study, the effects of a novel selective 5-hydroxytryptamine type 2C (5-HT) receptor agonist, TAK-233, on evoked momentary urethra-closing functions were investigated in female rats and humans to elucidate 5-HT receptor functions. In anesthetized female rats, TAK-233 dose-dependently and significantly increased the urethral resistance during sneezing in rats with distended vaginas and bilaterally transected pelvic nerves. The drug also dose-dependently and significantly increased urethral resistance during momentary intravesical pressure elevation by electrical stimulation of abdominal muscles in rats with a transected spinal cord at the T8-9 level and intact pelvic nerves.

Self-contained system for mitigation of contaminated aerosol sources of SARS-CoV-2 .

Res Sq 2021 Feb 24. Epub 2021 Feb 24.

Contaminated aerosols and micro droplets are easily generated by infected hosts through sneezing, coughing, speaking and breathing and harm humans’ health and the global economy. While most of the efforts are usually targeted towards protecting individuals from getting infected, eliminating transmissions from infection sources is also important to prevent disease transmission. Supportive therapies for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV-2) pneumonia such as oxygen supplementation, nebulizers and non-invasive mechanical ventilation all carry an increased risk for viral transmission via aerosol to healthcare workers.

The antireflux mechanism - Angiographic anatomy and clinical implications.

Interv Neuroradiol 2020 Dec 14;26(6):691-702. Epub 2020 Jul 14.

Division of Interventional Neuroradiology, The Johns Hopkins Hospital, Baltimore, MD, USA.

Background: Early anatomists suspected that the radiculomedullary veins draining the spinal cord had valves preventing their retrograde filling with anatomical casting material. Modern investigations have discarded the presence of true valves and introduced instead the notion of a pseudo-valvular configuration for which the term antireflux mechanism was coined in the 1970s. The angiographic anatomy of the antireflux mechanism has not been well documented so far. Read More

Effect of continuous positive airway pressure treatment on permeability, inflammation and mucus production of human epithelial cells.

ERJ Open Res 2020 Apr 8;6(2). Epub 2020 Jun 8.

Woolcock Institute of Medical Research, University of Sydney, Sydney, Australia.

Continuous positive airway pressure (CPAP) therapy is the gold standard treatment for obstructive sleep apnoea, which affects millions of people worldwide. However, this therapy normally results in symptoms such as dryness, sneezing, rhinorrhoea, post-nasal drip, nasal congestion and epistaxis in the upper airways. Using bronchial epithelial (Calu-3) and nasal epithelial (RPMI 2650) cells in an respiratory model, this study, for the first time, investigates the effect of CPAP positive pressure on the human respiratory epithelial mechanisms that regulate upper airways lubrication characteristics.

Division of Biomedical Engineering, Department of Life Science Engineering, Faculty of New Sciences and Technologies, University of Tehran, Tehran, Iran.

Stress urinary incontinence (SUI) or urine leakage from urethra occurs due to an increase in abdominal pressure resulting from stress like a cough or jumping height. SUI is more frequent among post-menopausal women. In the absence of bladder contraction, vesical pressure exceeds urethral pressure leading to urine leakage. Read More

Underwater nasal decongestant use: a novel approach to middle ear equalization.

Undersea Hyperb Med 2018 Nov-Dec;45(6):679-682

Department of Anesthesiology, University of Florida, Gainesville, Florida U.S.

Middle ear barotrauma is the most common diving-related injury. It is estimated to occur in more than 50% of experienced divers. Although divers learn how to effectively equalize their ears with various maneuvers, airway congestion may impede the ability to equalize the middle ear space via the Eustachian tube. Read More
