Pelvic venous insufficiency may cause pelvic congestion syndrome that is characterized by chronic pelvic pain exacerbated by prolonged standing, sexual activity or menstrual cycle. It may be treated by embolizing the dysfunctional pelvic venous drainage and sometimes resecting vulvar, perineal and thigh varices.

Replantation of a traumatic upper extremity amputation is a complex process accompanied by prolonged hospitalization, extended rehabilitation, and potential for graft failure secondary to poor perfusion to the distal extremity. The patient is faced with repeat visits to the operating room in addition to severe acute and chronic pain issues. We present the case of an 18-year-old male treated with prolonged continuous peripheral nerve blockade following traumatic left mid-humeral amputation and subsequent replantation. The patient maintained infraclavicular brachial plexus catheterization until hospital discharge, a course spanning 33 days and six follow-up surgical procedures. The patient was pain free and had been weaned off all opioids at a 4-week outpatient surgical debridement. Prolonged continuous infraclavicular brachial plexus blockade following replantation surgery has numerous potential benefits including augmentation of perfusion to the injured extremity, management of severe acute post-traumatic pain, and prevention of the chronic pain associated with transected nerves.

Aortic dissection (AD) is a serious condition in which the intimal layer of aorta tears and blood surges in between the intimal and medial layers of aorta causing it to separate (dissect). It usually presents with excruciating pain radiating to the back. Here we present a unique presentation of AD where an old-aged Caucasian male presented with a chronic history of intractable hiccups. His computed tomography (CAT scan) revealed the dissection of the descending thoracic aorta. He was managed conservatively and was discharged home in stable condition. The purpose of this report is to highlight this unusual presentation of AD and unmask the possible etiology of hiccups in such cases.

It is believed than hypothalamus (HTH) might be involved in generation of migraine, and evidence from high resolution fMRI reported that the more anterior part of HTH seemed to play an important role in migraine chronification. The current study was aimed to identify the alteration of morphology and resting-state functional connectivity (FC) of the hypothalamus (HTH) in interictal episodic migraine (EM) and chronic migraine (CM). High-resolution structural and resting-state functional magnetic resonance images were acquired in 18 EM patients, 16 CM patients, and 21 normal controls (NC). The volume of HTH was calculated and voxel-based morphometry (VBM) was performed over the whole HTH. Receiver operating characteristics (ROC) curve analysis was applied to evaluate the diagnostic efficacy of HTH volume. Correlation analyses with clinical variables were performed and FC maps were generated for positive HTH regions according to VBM comparison. The volume of the HTH significantly decreased in both EM and CM patients compared with NC. The cut-off volume of HTH as 1.429 ml had a good diagnostic accuracy for CM with sensitivity of 81.25% and specificity of 100%. VBM analyses identified volume reduction of posterior HTH in EM vs. NC which was negatively correlated with headache frequency. The posterior HTH presented decreased FC with the left inferior temporal gyrus (Brodmann area 20) in EM. Decreased volume of anterior HTH was identified in CM vs. NC and CM vs. EM which was positively correlated with headache frequency in CM. The anterior HTH presented increased FC with the right anterior orbital gyrus (AOrG) (Brodmann area 11) in CM compared with NC and increased FC with the right medial orbital gyrus (MOrG) (Brodmann area 11) in CM compared with EM. Our study provided evidence of structural plasticity and FC changes of HTH in the pathogensis of migraine generation and chronification, supporting potential therapeutic target toward the HTH and its peptide.

Although in clinical dentistry the major method used for pain relief is oral administration of analgesics, alternative methods are available, such as transcutaneous electrical nerve stimulation (TENS), acupuncture, vibration and conditioned pain modulation (CPM), formerly termed diffuse noxious inhibitory control. The aim of the present study was to investigate the combined effects of non-noxious (TENS) and noxious (CPM) stimuli on postoperative pain after extraction of an impacted wisdom tooth. The study involved 44 patients who were scheduled to undergo impacted wisdom tooth extraction. The patients were randomly allocated into four groups: noxious stimuli, non-noxious stimuli, combined noxious and non-noxious stimuli, and a sham group. On the day after tooth extraction, stimulation procedures for pain relief were performed and changes in the level of perceived pain were scored using a visual analog scale (VAS). The combination of non-noxious and noxious stimuli decreased the VAS scores by 63.7%, indicating a more potent analgesic effect than that in the non-noxious, noxious, and sham groups. This method of analgesia using a combination of non-noxious and noxious stimuli can be applied to patients who are unable to tolerate analgesics, such as those with allergy, hypersensitivity or digestive disorders, and those who are pregnant.

The objective for this clinical pilot study was to evaluate changes to chronic pain, vascular health, and inflammatory markers when consuming a dietary supplement blend (DSB, CytoQuel), containing curcumin, resveratrol, tocotrienols, N-Acetylcysteine, and epigallocatechin gallate. An open-label study design was used where 21 study participants were evaluated at baseline and at 2 and 8 weeks after consuming DSB. Participants were randomized to consume 3 capsules once daily versus 2 capsules twice daily. Pain and activities of daily living questionnaires were used to gather subjective data on pain levels and interference with daily living. Blood pressure was measured in both arms and ankles, and the ankle-brachial index (ABI) calculated. Blood samples were used to evaluate markers associated with inflammation and cardiovascular health. Highly significant reduction of chronic pain was seen after 8 weeks (<0.01), both at rest and when physically active. Faster improvement was seen when consuming 3 capsules once daily, compared to 2 capsules twice daily. The pain reduction resulted in improved sleep quality (<0.1), and improved social functioning (<0.01), and less need for support from others (<0.05), Normalization of mildly elevated ABI at study start was seen after 2 weeks. Plasma fibrinogen and von Willebrand Factor and serum matrix metalloproteinase-9 (MMP-9) showed reduction after 2 weeks (not significant), whereas a reduction in serum interleukin-1 receptor antagonist-a (IL-1ra) was statistically significant after 2 weeks (<0.05). Correlation between pain reduction and changes to MMP-9 after 8 weeks was highly significant (<0.01), whereas correlation between pain reduction and changes to IL-1ra reached significance at 2 weeks for the group consuming 3 caps once daily (<0.04). Consuming DSB helped manage pain, increased comfort during daily activities, and improved vascular function. This was associated with selective effects on specific blood biomarkers associated with inflammation and vascular health.

We present a unique case of vancomycin-induced drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome masquerading as elusive endocarditis. A 37-year-old female actively using intravenous drugs presented with worsening right upper extremity pain, fever, and chills. Workup revealed methicillin-resistant staphylococcus aureus (MRSA) bacteremia and multiple right-sided septic pulmonary emboli. Echocardiogram was negative for vegetation. Vancomycin was initiated for bacteremia management suspected secondary to right upper extremity abscesses. However, despite resolution of abscesses, fevers persisted, raising suspicion for endocarditis not detected by echocardiogram. On hospital day 25, the patient began showing signs of DRESS syndrome, ultimately manifesting as transaminitis, eosinophilia, and a diffuse, maculopapular rash. Vancomycin was switched to Linezolid and she improved on high dose steroids. The persistent fevers throughout this hospital course were thought to be an elusive endocarditis before DRESS syndrome fully manifested. Although Vancomycin-induced DRESS is uncommon, this case highlights the importance of identifying early signs of significant adverse effects.

Utilization of the emergency department (ED) by patients seeking relief from chronic pain (CP) has increased. These patients often face stigmatization, and the ED is no exception. The French-Canadian Chronic Pain Myth Scale (CPMS) was developed to evaluate common societal misconceptions about CP including among healthcare providers. To our knowledge, no tool of this nature is available in English.

Children frequently present with complaints of vertigo and/or disequilibrium. The etiology of such diagnoses include inner ear pathology, migraine and its variants, lesions of the central nervous system as well as mental health disorders, among others. The ability to reliably evaluate vestibular end-organ function is central to accurate diagnosis, however, examining children can be challenging. The current chapter will focus on the approach to assessing vestibular end-organ function in children, as well as the causes of vestibular impairment that are unique to this population.
