Porphyrias constitute a group of rare genetic diseases due to various, mostly autosomal dominant mutations, causing enzymatic deficiency in heme biosynthesis. As a result, neurotoxic porphyrin precursors and light-sensitive porphyrins accumulate, while dysfunction in their targets determines the disease symptoms. Variegate porphyria (VP), one of the acute hepatic porphyrias, is caused by a protoporphyrinogen oxidase (PPOX) mutation. During acute attacks, among other factors, triggered by drugs, stressors, or fasting, an increase in urinary and fecal porphobilinogen (PBG), aminolevulinic acid (ALA), and porphyrins occurs, damaging the autonomous, peripheral, or central nervous system. The disease remains often latent or displays minimal symptoms usually overlooked, exposing undiagnosed patients to potentially serious complications in the presence of the aforementioned triggers. This 46-year-old woman presented, some days after a bariatric surgery, with severe flaccid tetraparesis and neuropathic pain, initially misdiagnosed as a functional neurological disorder. The severe axonal sensorimotor polyneuropathy led to further investigations, disclosing high urinary porphobilinogen, ALA, and porphyrin levels due to a new PPOX mutation. Retrospectively, it appeared that the patient had had typical VP symptoms (abdominal pain, fragile skin, and dark urine episodes) for years prior to the surgery. Treated with carbohydrate load, neurorehabilitation, and analgesics, she slowly recovered to full mobility, with partial autonomy in her daily life activities, although fatigue and severe pain persisted, preventing her from returning to work. This case documents gastric bypass surgery as a trigger of severe VP invalidating neurological symptoms and illustrates how the delayed diagnosis and post-interventional complications could have been prevented by screening for porphyria cardinal symptoms prior to the intervention. Likewise, this cost-effective screening should be performed before any treatment influencing the diet, which would dramatically improve the porphyria diagnosis rate and outcome.

Migraineurs are often plagued by sleep disorders. The university student population is high in number and is more vulnerable to migraines. However, no study has analyzed the sleep quality of students with migraine and related contributing factors. We used the Pittsburgh Sleep Quality Index (PSQI) scale to assess the sleep of migraine patients among college students and to explore the influencing factors of sleep quality. We performed primary screening for migraine using the ID-migraine screening, and further assessed headache characteristics, sleep, anxiety, depression, and mobile phone addiction in college students with positive primary screening, then diagnosed migraine according to the third edition of (ICHD-3). Finally, we analyzed the factors influencing sleep quality using Binary Logistic Regression Analysis. Those with scores greater than 5 points on the PSQI scale were believed to have poor sleep quality. The prevalence of migraine was 6.6%. A total of 545 migraineurs were eventually included in the analysis, the incidence of poor sleep quality was 64.04%. The three factors of experiencing aura (OR = 2.966, 95%CI = 1.756-5.010, < 0.05), anxiety (OR = 2.778, 95%CI = 1.434-5.382, < 0.05), and high Mobile phone addiction index (MPAI) score (OR = 1.025, 95%CI = 1.002-1.049, < 0.05) contributed enormously to poor sleep quality. Moreover, the factors of aura symptoms (OR = 3.796, 95%CI = 2.041-7.058, < 0.05), anxiety (OR = 3.146, 95%CI = 1.473-6.719, < 0.05), and MPAI score (OR = 1.028, 95%CI = 1.002-1.054, < 0.05) influenced the sleep quality of female migraineurs rather than male migraineurs. The incidence of poor sleep quality is high among university students with migraine. Aura symptoms, anxiety, and high MPAI score influence the sleep quality of migraineurs, especially females. The proposal of prevention and intervention measures is of great importance to the physical and mental health of students with migraine. identifier ChiCTR1800014343.

We report a case of the middle cerebral artery (MCA) M1 segment ruptured fusiform aneurysm that was successfully treated using a domestic Tubridge flow diverter (TFD). A 40-year-old man was admitted to the hospital because of a headache and was diagnosed with subarachnoid hemorrhage. Cerebral angiography revealed a ruptured fusiform aneurysm in the M1 segment of the right MCA. TFD, combined with coil embolization, was used for perioperative treatment. No obvious complications were observed. Follow-up digital subtraction angiography 2 and 12 months after the surgery showed that the aneurysm was occluded, and the patient recovered well. This is the first known case of this treatment with this type of stent in such an aneurysm and demonstrates that TFD can be used to treat ruptured fusiform aneurysms in the M1 segment of the MCA.

Intestinal neuronal dysplasia (IND) is a rare condition mainly affecting the children. Constipation and abdominal distension have been reported as common manifestations. In addition, the reports about adult cases are scarce.

The pain pattern after laparoscopic cholecystectomy (LC) is complex and distinct from postoperative pain after other laparoscopic procedures, suggesting that procedure-specific optimal analgesic management plans should be proposed. Duloxetine, a non-opioid neuromodulator, has been widely used to manage pain with dual central and peripheral analgesic properties. To assess the effect of preoperative administration of duloxetine compared to placebo on postoperative pain control in patients undergoing LC. This study was a randomized, parallel-group, placebo-controlled, double-blinded study performed on patients undergoing LC. Patients were randomly divided into two groups of 30 each on the day of surgery in the preoperative holding area, using a computer-generated random number to receive 60 mg duloxetine as a single oral dose 2 h before the procedure or placebo. The primary outcome was the difference in the mean of visual analogue scale (VAS) scores between the two studied groups, as measured by the area under the curve (AUC) of the VAS scores. The derived AUC of VAS scores in the duloxetine group (757.89 ± 326.01 mm × h) was significantly lower than that calculated for the control group (1005.1 ± 432.5 mm × h). The mean postoperative VAS scores recorded at 4 and 24 h were statistically different between the study groups ( = 0.041 and 0.003, respectively). As observed in the survival curve analysis, there was no significant difference ( = 0.665) for the time until the patient's first request for rescue medications in the two groups. The frequency of postoperative nausea and vomiting (PONV) was lower in patients of the duloxetine group than that recorded in those allocated to the control group at 8 and 24-h time intervals ( = 0.734 and 0.572, respectively). Preoperative use of duloxetine reduces postoperative pain significantly compared with placebo. In addition, its use is associated with a reduction in PONV. These preliminary findings suggest that duloxetine could play a role in the acute preoperative period for patients undergoing LC.

Abnormal angiogenesis and innervation in avascular discs during lumbar disc degeneration (LDD) cause severe back pain. These pathological alterations in the degenerating discs are induced by cytokines partially produced and secreted by inflammatory cells, among which macrophages are the most frequently ones detected at the legion site. However, the role of macrophages as well as their polarization in regulation of innervation and angiogenesis in the degenerating discs is unclear. In this study, we analyzed macrophages in the degenerating discs from patients and detected a specific macrophage subtype that expresses high levels of vascular endothelial growth factor A (VEGF-A). Co-expression of M2 macrophage markers in this macrophage subtype suggested that they were a M2d-like subtype. High levels of VEGF-A and genes associated with angiogenesis were also detected in LDD specimens compared to control heathy discs from a public database, consistent with our finding. Moreover, the levels of VEGF-A in disc macrophages were strongly correlated to the pain score of the examined patients, but not to the Thompson classification of the degeneration level of the patients. , overexpressing VEGF-A in macrophages increased the tube formation, proliferation and migration of co-cultured endothelial cells, and increased the innervation of embryonic spinal cord explant into the co-cultured area for macrophages and skeletal myocytes. , an orthotopic injection of adeno-associated virus carrying siRNA for VEGF-A under a macrophage-specific CD68 promoter significantly reduced the number of VEGF-A-positive disc macrophages and alleviated the pain in LDD-mice. Together, these data suggest that inhibition of angiogenetic potential of macrophages may reduce disc degeneration-associated pain through suppression of angiogenesis and innervation, as a promising therapy for LDD-associated pain.

Regional anesthesia is frequently employed in efforts to improve postoperative analgesia and reduce opioid requirements following abdominal surgery. The purpose of the current analysis was to determine if there was a difference in postoperative pain and opioid consumption between patients who underwent open total abdominal hysterectomy (TAH) and received ultrasound-guided bilateral transversus abdominis plane (TAP) blocks using either liposomal bupivacaine or ropivacaine. A single-center retrospective analysis was conducted of 215 patients from November 2018 through March 2020 who underwent an open TAH and received bilateral TAP blocks with either liposomal bupivacaine or ropivacaine. The primary outcome measure was opioid consumption at regular intervals until discharge, and the secondary outcome measures included pain scores, incidence of nausea/vomiting, and use of antiemetics at the same time intervals. Intraoperative opioid consumption and postanesthesia recovery unit opioid requirements were similar between the two groups. Opioid requirements at 24 hours ( < 0.04) and 48 hours ( < 0.01), as well as total morphine equivalent requirements ( < 0.05), were significantly lower in the liposomal bupivacaine group compared to the ropivacaine group. Patients undergoing open TAH who received liposomal bupivacaine TAP blocks required fewer postoperative opioids to achieve similar pain scores when compared to patients who received ropivacaine TAP blocks.

Patients with dysphagia often have an esophageal disorder. This case report describes a patient with persistent dysphagia and chest pain who had a normal esophagogastroduodenoscopy. Computed tomography of the chest with contrast revealed an aberrant right subclavian artery compressing the esophagus. A vascular procedure was performed and corrected the dysphagia. This case demonstrates that aberrant vessels can occasionally cause dysphagia.

We present a rare case of Mollaret's meningitis in a young patient with seven prior episodes of recurrent meningitis. The patient presented with headache, fever, neck stiffness, nausea, and vomiting. Brain imaging revealed no acute abnormalities. Lumbar puncture revealed elevated nucleated cells with lymphocytic predominance. The patient was started on antimicrobials including acyclovir. Cerebrospinal fluid polymerase chain reaction was positive for herpes simplex virus type 2. Her 2-day hospital course was uncomplicated, and she was discharged in good condition. Mollaret's meningitis, also known as recurrent benign lymphocytic meningitis, is a rare clinical disorder characterized by at least three recurrent episodes of meningitis associated with spontaneous recovery with or without antiviral therapy. Herpes simplex virus type 2 has frequently been implicated in the setting of this illness.
