When upper respiratory tract infections go rogue: A case report of Cerebral Abscess.

is an extremely rare cause of cerebral abscess. We present a unique case of sinusitis complicated by preseptal cellulitis and cerebral abscess. The patient initially presented with pharyngitis and then developed sinus congestion, headache and facial pain. Computed tomography and magnetic resonance imaging revealed a right gyrus rectus cerebral abscess and paranasal sinus infection. The patient underwent endoscopic sinus surgery and cultures revealed . Repeat imaging revealed maturation and progression of intracranial abscess. The abscess was drained and patient was treated with parenteral and oral antibiotics until complete clinical and radiological remission. This case highlights the importance of recognizing as a cause of invasive disease in immunocompetent hosts.

Long Non-coding RNA Uc.48+ Small Interfering RNA Alleviates Neuroinflammatory Hyperalgesia in Gp120-Treated Rats via the P2Y12 Receptor.

Human immunodeficiency virus envelope glycoprotein 120 (gp120) leads to hyperalgesia. Long non-coding RNAs are characterized by the lack of a protein-coding sequence and may contribute to the development and maintenance of inflammatory and neuroinflammatory pain. Rats with neuroinflammatory pain were established by gp120 treatment, which is featured by intensified pain behaviors. Long non-coding RNA uc.48+ was increased in the dorsal root ganglia of gp120-treated rats, and small interfering RNA that targets uc.48+ markedly alleviated hyperalgesia in gp120-treated rats. Notably, uc.48+ overexpression increased P2Y12 expression in control rats dorsal root ganglia and induced hyperalgesia. Uc.48+ small interfering RNA inhibited P2Y12 expression in gp120-treated rats. Uc.48+ potentiated P2Y12 receptor functions in the neurons and heterologous cells. Therefore, uc.48+ siRNA treatment reduced the upregulation of P2Y12 expression and function in DRG neurons, and, hence, alleviated hyperalgesia in gp120-treated rats.

Atypical odontalgia and trigeminal neuralgia: psychological, behavioural and psychopharmacologic approach – an overview of the pathologies related to the challenging differential diagnosis in orofacial pain.

Orofacial pain represents a challenge for dentists, especially if with a non-odontogenic basis. Orofacial neuropathic pain is chronic, arduous to localize and develops without obvious pathology. Comorbid psychiatric disorders, such as anxiety and depression, coexist and negatively affect the condition. This article presents one case of atypical odontalgia and one of trigeminal neuralgia treated with psychological and psychopharmacologic tailored and adapted therapies, after conventional medications had failed.  In addition, an overview of the pathologies related to the challenging differential diagnosis in orofacial pain is given, since current data are insufficient.   A 68-year-old male complained of chronic throbbing, burning pain in a maxillary tooth, worsening upon digital pressure. Symptoms did not abate after conventional amitriptyline therapy; psychological intervention and antianxiety drug were supplemented and antidepressant agent dosage incremented; the patient revealed improvement and satisfaction with the multidisciplinary approach to his pathology. A 72-year-old male lamented chronic stabbing, intermittent, sharp, shooting and electric shock-like pain in an upper tooth, radiating and following the distribution of the trigeminal nerve. Pain did not recur after psychological intervention and a prescription of antidepressant and antianxiety agents, while conventional carbamazepine therapy had not been sufficient to control pain. Due to concern with comorbid psychiatric disorders, we adopted a patient-centered, tailored and balanced therapy, favourably changing the clinical outcome.  Comorbid psychiatric disorders have a negative impact on orofacial pain and dentists should consider adopting tailored therapies, such as psychological counselling and behavioural and psychopharmacologic strategies, besides conventional treatments. They also need to be familiar with the signs and symptoms of orofacial pain, recollecting a comprehensive view of the pathologies concerning the differential diagnosis. A prompt diagnosis prevents pain chronicity, avoiding an increase in complexity and a shift to orofacial neuropathic pain and legal claims.

An Investigation of Descending Pain Modulation in Women With Provoked Vestibulodynia (PVD): Alterations of Spinal Cord and Brainstem Connectivity.

The most common subtype of vulvodynia (idiopathic chronic vulvar pain) is provoked vestibulodynia (PVD). Previous imaging studies have shown that women with vulvodynia exhibit increased neural activity in pain-related brain regions (e.g., the secondary somatosensory cortex, insula, dorsal midcingulate, posterior cingulate, and thalamus). However, despite the recognized role of the spinal cord/brainstem in pain modulation, no previous neuroimaging studies of vulvodynia have examined the spinal cord/brainstem. Sixteen women with PVD and sixteen matched Control women underwent a spinal cord/brainstem functional magnetic resonance imaging (fMRI) session consisting of five runs with no painful thermal stimuli (No Pain), interleaved randomly with five runs with calibrated, moderately painful heat stimulation (Pain). Functional connectivity was also assessed in periods before, during, and after, pain stimulation to investigate dynamic variations in pain processing throughout the stimulation paradigm. Functional connectivity in the brainstem and spinal cord for each group was examined using structural equation modeling (SEM) for both Pain and No Pain conditions. Significant connectivity differences during stimulation were identified between PVD and Control groups within pain modulatory regions. Comparisons of Pain and No Pain conditions identified a larger number of connections in the Control group than in the PVD group, both before and during stimulation. The results suggest that women with PVD exhibit altered pain processing and indicate an insufficient response of the pain modulation system. This study is the first to examine the spinal cord/brainstem functional connectivity in women with PVD, and it demonstrates altered connectivity related to pain modulation in the spinal cord/brainstem.

The Potential Relationship Between Environmental Endocrine Disruptor Exposure and the Development of Endometriosis and Adenomyosis.

Women with endometriosis, the growth of endometrial glands and stroma outside the uterus, commonly also exhibit adenomyosis, the growth of endometrial tissues within the uterine muscle. Each disease is associated with functional alterations in the eutopic endometrium frequently leading to pain, reduced fertility, and an increased risk of adverse pregnancy outcomes. Although the precise etiology of either disease is poorly understood, evidence suggests that the presence of endometriosis may be a contributing factor to the subsequent development of adenomyosis as a consequence of an altered, systemic inflammatory response. Herein, we will discuss the potential role of exposure to environmental toxicants with endocrine disrupting capabilities in the pathogenesis of both endometriosis and adenomyosis. Numerous epidemiology and experimental studies support a role for environmental endocrine disrupting chemicals (EDCs) in the development of endometriosis; however, only a few studies have examined the potential relationship between toxicant exposures and the risk of adenomyosis. Nevertheless, since women with endometriosis are also frequently found to have adenomyosis, discussion of EDC exposure and development of each of these diseases is relevant. We will discuss the potential mechanisms by which EDCs may act to promote the co-development of endometriosis and adenomyosis. Understanding the disease-promoting mechanisms of environmental toxicants related to endometriosis and adenomyosis is paramount to designing more effective treatment(s) and preventative strategies.

Paeonol Ameliorates Chronic Itch and Spinal Astrocytic Activation via CXCR3 in an Experimental Dry Skin Model in Mice.

Paeonol is a bioactive phenol presents mainly in Andr. (), Pall., and Thunb. (), harboring various pharmacological activities including anti-inflammatory, antioxidant, immune regulatory activity and reverse chemoresistance. Recent reports revealed paeonol exhibited good effects on chronic dermatitis, such as atopic dermatitis (AD) and psoriasis. However, whether paeonol is effective for dry skin disease and its mechanism of action still remain unclear. In this study, we analysed the effects of paeonol on a mouse model of dry skin treated with acetone-ether-water (AEW), which showed impressive activities in reducing scratching behavior and skin inflammation. To elucidate the underlying molecular targets for the anti-pruritic ability of paeonol, we screened the expression of possible chemokine pathways in the spinal cord. The expression of CXCR3 was significantly alleviated by paeonol, which increased greatly in the spinal neurons of AEW mice. In addition, treatment of paeonol significantly inhibited AEW-induced expression of astrocyte activity-dependent genes including , and et al. The inhibitory effects of paeonol on scratching behavior and astrocytic activation in the spinal cord induced by AEW were abolished when CXCR3 was antagonized or genetically ablated. Taken together, our results indicated that paeonol can ameliorate AEW-induced inflammatory response and itching behavior, and reduce the expression of spinal astrocyte activity-dependent genes induced by AEW, which are driven by CXCR3.

Causes Intracranial Infection: A Case Study.

is a rarely encountered bacterium in clinical practice. It is a rare gram-negative rod-shaped bacterium associated with lung and urinary tract infections, but never found in cerebrospinal fluid. This paper reports a case of an adult patient infected by via an unknown route of infection causing a severe intracranial infection. was detected by culture and Metagenomic next generation sequencing in CSF. Early identification of this strain and treatment with sensitive antibiotics is necessary to reduce morbidity and mortality. A 24-year-old male was admitted to a West China Hospital because of headache and vomiting for 2 months. Symptom features included acute onset and long duration of illness. Notably, headache and vomiting were the primary neurological symptoms. Routine cerebrospinal fluid culture failed to identify the bacterium; however, bacterium was detected via second-generation sequencing techniques. was found to be a multi-drug resistant organism, hence, treatment with ceftriaxone, a commonly used drug for intracranial infections was ineffective. This strain eventually caused severe intracranial infection resulting in the death of the patient. In summary, this study comprehensively describes a case of an adult patient infected by and discusses its early identification as well as application of sensitive antibiotics in the emergency setting.
