BACKGROUND: The latissimus dorsi (LD) is often used for tendon transfers to treat massive irreparable posterosuperior rotator cuff tears. The operation requires the LD tendon to be mobilized to reduce tension on the tendon. In that respect, any connection between the LD tendon and contiguous muscles may hamper tendon mobility and affect the surgical outcome. The goal of this study was to document the occurrence of connections between the LD and adjacent muscles and nerves. METHODS: We studied the scapular region on 48 embalmed cadavers...

Russell M Levine, Alina Yang, Venkatesh Brahma, James F Martone
PURPOSE OF REVIEW: Ocular perfusion pressure (OPP) is defined as the difference between BP and intraocular pressure (IOP). With low BP comes low OPP and resultant ischemic damage to the optic nerve, leading to glaucoma progression. The purpose of this article is to review the literature on BP as it relates to glaucoma and to create a forum of discussion between ophthalmologists and internal medicine specialists. RECENT FINDINGS: Both high and low BP has been linked glaucoma...

REVIEW

De Quervain tenosynovitis is often treated by simple release of the first compartment. However, patients can suffer from persistent postoperative problems, including "clumsy" use of the thumb, as a result of redislocation or bowstringing of the extensor pollicis brevis/abductor pollicis longus tendons or irritation of the superficial branch of the radial nerve. Here we describe our method for first compartment reconstruction, in which the flaps are sutured after double-flap incision of the compartment. Because the tendons can become recompressed or redislocate if the sutures are too tight or loose, respectively, we achieve proper tension by suturing the flaps with the patient fully awake, under local anesthesia, and without a tourniquet...

This study reports the case of an acoustic shock injury (ASI), which did not result in a significant hearing loss, but was followed by manifold chronic symptoms both within (tinnitus, otalgia, tingling in the ear, tension in the ear, and red tympanum) and outside the ears (blocked nose, pain in the neck/temporal region). We suggest that these symptoms may result from a loop involving injury to middle ear muscles, peripheral inflammatory processes, activation and sensitization of the trigeminal nerve, the autonomic nervous system, and central feedbacks...

Keloids are caused by excessive scar formation that leads to scar growth beyond the initial scar boundaries. Keloid formation and progression is promoted by mechanical stress such as skin stretch force. Consequently, keloids rarely occur in paralyzed areas and areas with little skin tension, such as the periauricular region. Therefore, periauricular incision is commonly performed for face lifts. We report a rare case of keloids that arose from face-lift scars in a patient with bilateral facial nerve paralysis...

The present study investigated changes in autonomic nervous system activity and emotions after a short (2 h) forest bathing program in the Xitou Nature Education Area (XNEA), Taiwan. One hundred and twenty-eight (60.0 ± 7.44 years) middle-aged and elderly participants were recruited. Physiological responses, pulse rate, systolic and diastolic blood pressure, heart rate variability (HRV), and psychological indices were measured before and after the program. We observed that pulse rate, systolic and diastolic blood pressure were significantly lower after the program, which indicated physiological benefits from stress recovery...

Following traumatic brain injury (TBI), ischemia and hypoxia play a major role in further worsening of the damage, a process referred to as 'secondary injury'. Protecting neurons from causative factors of secondary injury has been the guiding principle of modern TBI management. Stimulation of trigeminal nerve induces pressor response and improves cerebral blood flow (CBF) by activating the rostral ventrolateral medulla. Moreover, it causes cerebrovasodilation through the trigemino-cerebrovascular system and trigemino-parasympathetic reflex...

Estrogens have an important role in regulating detrusor smooth muscle (DSM) function. However, the underlying molecular and cellular mechanisms by which estrogens control human DSM excitability and contractility are not well known. Here, we used human DSM specimens from open bladder surgeries on 27 patients to elucidate the mechanism by which 17β-estradiol regulates large conductance voltage- and Ca(2+)-activated K(+) (BK) channels, the most prominent K(+) channels in human DSM We employed single BK channel recordings on inside-out excised membrane patches, perforated whole-cell patch-clamp on freshly isolated DSM cells, and isometric tension recordings on DSM-isolated strips to investigate the mechanism by which 17β-estradiol activates BK channels...

Normal tension glaucoma (NTG) also known as low tension glaucoma, presents with optic nerve head and visual field damage in the absence of high intraocular pressure (<21 mmHg). There are several patients of NTG seen in our clinics who have repeatable visual field defects, which may or may not correlate with the disc appearance, but are labeled as glaucoma. Ruling out ischemic, nutritional, and other causes of one-time damage are important before diagnosing an NTG. We report 3 such cases that were misdiagnosed and referred as NTG...

Glaucoma, one of the leading causes of irreversible blindness, is characterized by progressive degeneration of optic nerves and retinal ganglion cells (RGCs). In the mammalian retina, excitatory amino-acid carrier 1 (EAAC1) is expressed in neural cells, including RGCs. Loss of EAAC1 leads to RGC degeneration without elevated intraocular pressure (IOP) and exhibits glaucomatous pathology including glutamate neurotoxicity and oxidative stress. In the present study, we found that edaravone, a free radical scavenger that is used for treatment of acute brain infarction and amyotrophic lateral sclerosis (ALS), reduces oxidative stress and prevents RGC death and thinning of the inner retinal layer in EAAC1-deficient (KO) mice...

We repeatedly examined 17 subjects with presumed bilateral physiological excavation labeled as pathological and/or borderline via HRT to verify the diagnosis of physiological cupping or to monitor the long-term progression into normal tension glaucoma. Patients and Methods 17 Subjects with presumed bilateral physiological cupping and large optic discs were included in this long-term follow-up study. All subjects underwent regular detailed ophthalmologic examinations, including intraocular pressure measurement via Goldmann applanation tonometry (GAT), retinal nerve fiber layer imaging via optical coherence tonometry (OCT) and visual field testing and optic disc imaging using the HRT...

AIMS: Mechanoafferent and peristaltic mechanisms of the human ureter involve transient receptor potential V1 (TRPV1)- and purinoceptor-mediated functions. Hydrogen sulphide, an endogenous TRPA1 ligand, is linked to inhibitory neurotransmission of the pig ureter. No information is available on TRPA1 activity in the human ureter. We therefore examined the distribution and function of TRPA1 in the human ureter. METHODS: Expression of TRPA1 in human ureter tissue was studied by Western blot and immunofluorescence...
