Macular amyloidosis is a common type of primary localized cutaneous amyloidosis. We present a case report of a 74-year-old patient with no significant past medical history who was evaluated for dark macules and pruritus for over a year. On exam, follicular-based brown macules on the upper and lower back, bilateral shoulders, and bilateral dorsal upper arms were noted. The morphology and distribution of follicular-based macules was unusual, so the differential included follicular lichen planus, follicular eczema, and macular amyloidosis. Punch biopsy showed deposits of eosinophilic fibrillary material along with pigmentary incontinence in the papillary dermis, consistent with macular amyloidosis. Additionally, there was some trapping of the adnexal structures with atrophy of the periadnexal fat in the reticular dermis. In macular amyloidosis keratin, intermediate filaments such as cytokeratin serve as the amyloid precursors which deposit in the superficial dermis. Characteristically, macular amyloidosis presents as hyperpigmented macules or patches, often in a "rippled" linear pattern. This case highlights a rare presentation of macular amyloidosis because of the atypical follicular involvement and emphasizes the variety of presentations for localized cutaneous amyloidosis. Additionally, new treatment options such as Janus Kinase inhibitors and their potential role in the pathological pathway are discussed.

Lung endothelial permeability is a key pathological feature of acute respiratory distress syndrome. Hyaluronic acid (HA), a major component of the glycocalyx layer on the endothelium, is generated by HA synthase (HAS) during inflammation and injury and is critical for repair. We hypothesized that administration of exogenous high molecular weight (HMW) HA would restore protein permeability across human lung microvascular endothelial cells (HLMVEC) injured by an inflammatory insult via upregulation of HAS by binding to CD44. A transwell coculture system was used to study the effects of HA on protein permeability across HLMVEC injured by cytomix, a mixture of IL-1β, TNFα, and IFNγ, with or without HMW or low molecular weight (LMW) HA. Coincubation with HMW HA, but not LMW HA, improved protein permeability following injury at 24 h. Fluorescence microscopy demonstrated that exogenous HMW HA partially prevented the increase in "actin stress fiber" formation. HMW HA also increased the synthesis of HAS2 mRNA expression and intracellular HMW HA levels in HLMVEC following injury. Pretreatment with an anti-CD44 antibody or 4-methylumbelliferone, a HAS inhibitor, blocked the therapeutic effects. In conclusion, exogenous HMW HA restored protein permeability across HLMVEC injured by an inflammatory insult in part through upregulation of HAS2.

The purpose of this study was to determine the effects of premorbid headache status on vestibular and oculomotor baseline tests in collegiate club athletes.

Dental care practitioners are often the first port of call for patients presenting with acute dental pain. Due to the increasing backlog of patients in the UK resulting from the COVID-19 pandemic, it is expected that an increasing number of patients will present to dental care practitioners with acute dental problems. This article aims to provide an overview of common presentations of acute dental pain, the importance of thorough assessment and accurate diagnosis, and the management of such conditions.

Chordomas are midline tumors that arise from remnants of the primitive notochord, while the heterotopic rests are usually situated extradural within the bones of the axial skeleton. The tumor is locally aggressive with a high recurrence rate but rarely gives rise to metastasis.

Total pancreatectomy with islet autotransplantation (TPIAT) is a surgical procedure undertaken in some patients with severe pain or disability from recurrent acute and chronic pancreatitis (CP). TPIAT provides a rare opportunity to study human pancreas tissue from patients affected with pancreatitis, and particularly from patients with genetic forms of pancreatitis. Research to date suggests distinct histopathology and potentially differential pathophysiology of distinct etiologies of CP. Histopathology specimens have helped better define the success and limitations of clinical diagnostic imaging tools, such as magnetic retrograde cholangiopancreatography and endoscopic ultrasound.

Eyelid basal cell carcinoma (BCC) is usually cured by surgery. However, for a minority of patients, extensive disease progression and recurrence contraindicate surgery or radiotherapy because of severe ocular morbidity. The hedgehog signaling pathway inhibitor vismodegib is becoming the key treatment for this specific form.

Surgical trauma initiates changes in central and peripheral nervous systems that need to be treated therapeutically to facilitate postoperative pain. The quality of postoperative analgesia is expected to affect clinical outcomes positively. Albeit optimal pain relief following cardiac surgery is often complex, researchers have tried to explore several techniques other than conventional ones during the last decade to find a unique analgesic method for postcardiac surgical patients. This study aims to find a unique analgesic approach that maximizes patient satisfaction after off-pump coronary artery bypass graft (OPCABG) surgery.

We aimed to investigate the prevalence and factors associated with long-term opioid use among patients with chronic non-cancer pain (CNCP).

Ten to 12 percent of the adult population globally suffers from migraine, which is the second most frequent type of primary headache, according to the American Academy of Neurology. Even though pain and attack-related impairment scored first, cognitive symptoms were the second most common. ; The current study intended to measure the latency of P300 wave during and after an acute attack of migraine among a group of patients known to have migraine in order to introduce an objective method to measure the cognitive function of migraineurs during migraine attack. ; This is a potential cohort study conducted at the neurological outpatient's clinics of Basra hospitals to the period from January until August 2021. The total number of subjects included in the study were forty-eight (48), thirty (30) patients and eighteen (18) age and gender matched control subjects. Patients were examined and selected by senior neurologist and diagnosed as having common migraine, then refereed to the neurophysiology clinic to perform cognitive function tests, for each patient two tests were done; first one during the acute migraine attack and second one after one month far ahead from the end of the migraine attack. In addition, one cognitive function test was done for the control group.; We discovered a highly important variance of the mean P300 latency of the patients during the acute attack of migraine as compared to the same group of the patients after repeating the exam one month far ahead from the end of the last migraine attack and one week ahead of being medication free. Also, we found the mean P300 latency of the patients during the acute attack of migraine is significantly higher than the mean P300 latency of the control subjects (P. value <0.00).; We found that all migraineurs in our study are having higher P300 latency values than control group during moderate migraine attack and this difference was significant which indicates that during moderate migraine attacks there is obvious impairment of cognitive performance abilities of those patients.
