Chronic pain patients often develop mental disorders, and anxiety disorders are common. We hypothesize that the comorbid anxiety results from an imbalance between the reward and antireward system due to persistent pain, which leads to the dysfunction of the pain and anxiety regulatory system. In this review, we will focus on changes in neuroplasticity, especially in neural circuits, during chronic pain and anxiety as observed in animal studies. Several neural circuits within specific regions of the brain, including the nucleus accumbens, lateral habenular, parabrachial nucleus, medial septum, anterior cingulate cortex, amygdala, hippocampus, medial prefrontal cortex, and bed nucleus of the stria terminalis, will be discussed based on novel findings after chemogenetic or optogenetic manipulation. We believe that these animal studies provide novel insights into human conditions and can guide clinical practice.

Diabetes is a chronic disease caused by defective insulin secretion in the body, resulting in metabolic abnormalities with persistent blood glucose elevation. Osteoporosis is the most common diabetes complication. The aim of this study was to perform a meta-analysis of the effects of alendronate combined with atorvastatin compared with alendronate alone in the treatment of osteoporosis in diabetes mellitus.

Purpose Patients complain of moderate-intensity pain following thyroid surgery. Superficial cervical plexus block (SCPB) can be employed as a component of multimodal analgesia after thyroid surgery. This double-blind, randomized study aimed to compare the effects of bilateral SCPB (BSCPB) on postoperative analgesic requirements following thyroid surgery. Methods A total of 60 American Society of Anesthesiologists (ASA) I-II patients who underwent elective total thyroidectomy under general anesthesia were randomly assigned to Group 1 and Group 2. After inducing general anesthesia, BSCPB was not administered to Group 1, whereas BSCPB was administered using a three-point injection technique with 0.5% levobupivacaine in Group 2. Patient-controlled analgesia (PCA) was applied by using tramadol in both groups for postoperative analgesia. Tenoxicam was administered as rescue analgesic to patients in case of numeric rating scale (NRS) >4. The postoperative consumption of tramadol, rescue analgesic requirement, and hoarseness, hematoma, signs of local anesthetic toxicity were recorded. Results The consumption of tramadol for PCA at two, six, 12, and 24 hours postoperatively, NRS scores in the recovery room, and the number of patients who used tenoxicam as rescue analgesic were significantly lower in Group 2 than in Group 1. The hemodynamic values were similar between the groups. Conclusions Our study demonstrates that BSCPB, when applied as a component of multimodal analgesia, is an effective method for reducing the analgesic requirements following thyroid surgery.

Sarcoidosis is a granulomatous disease with multiple system involvement. It is characterized by the presence of non-caseating granulomas in the involved organs. The most commonly affected organ in sarcoidosis is the pulmonary interstitium. However, extra-pulmonary involvement can be manifested in almost any other organ system. Less commonly, sarcoidosis can manifest with massive splenomegaly. As extensive differential diagnoses, such as hematological malignancies, primary splenic or metastatic tumors, infiltrative disorders, and inflammatory disorders are considered, diagnosing sarcoidosis with the presentation of massive splenomegaly is clinically challenging. Here, we discuss the case of a 56-year-old female with splenic sarcoidosis and skin manifestation.

Peritoneal cancer is a rare disease that typically affects middle-aged women. Sclerosing mesenteritis can have a benign or malignant etiology. Although computed tomography (CT) scan and magnetic resonance imaging have been used to differentiate these two diseases, the findings are not always conclusive. Here, we report the case of an older woman who presented with acute abdominal pain. She was initially diagnosed with sclerosing mesenteritis, but the final diagnosis was peritoneal cancer. The initial treatment included antibiotics, non-steroidal anti-inflammatory drugs, and prednisolone. Tamoxifen was administered due to persistent symptoms, which were alleviated. However, the patient's cancer antigen 125 levels were elevated, and there were changes in the peritoneal CT findings. The patient was diagnosed with primary peritoneal cancer based on further investigation of the peritoneum using positron emission tomography-CT and a biopsy. This case report describes the diagnostic process regarding the differentiation between sclerosing mesenteritis and primary peritoneal cancer when the CT findings mimic those of sclerosing mesenteritis in general medicine.

To compare the effectiveness and tolerability of add-on treatment with nabiximols (NBX: delta-9-tetrahydrocannabinol: cannabidiol) oromucosal spray or oral dronabinol (DRO: synthetic tetrahydrocannabinol) in patients with severe neuropathic pain poorly responsive to established treatments.

Resting-state functional MRI is widely used in migraine research. However, the pathophysiology and imaging markers specific for migraine pathologies are not well understood. In this study, we combined both structural and functional images to explore the concurrence and process of migraines.

Cystic artery pseudoaneurysm is a rare complication of invasive biliary procedures or of acute or chronic cholecystitis and pancreatitis. Emphysematous cholecystitis is an acute inflammatory process of the gallbladder due to gas forming organisms such as and . We report the case of a 34-year-old gentleman admitted with a 3-day history of generalized abdominal pain, vomiting and markedly raised inflammatory markers. A computed tomography scan demonstrated acute calculus cholecystitis and an incidental CAP. This was successfully treated with an emergency laparoscopic cholecystectomy. CAPs are reported in the literature as rare and are usually diagnosed after rupture with severe haemorrhage. In this report, we highlight that a non-ruptured CAP identified preoperatively can be safely managed simultaneously with a laparoscopic approach, thus avoiding the need for invasive angiographic procedures or open surgery.

We report a clinical case, where COVID-19 presented with a thunderclap headache and collapse, but no fever or respiratory symptoms on initial presentation. The patient was worked up for a possible spontaneous subarachnoid haemorrhage (SAH), but had a normal CT brain and normal lumbar puncture and then very rapidly deteriorated with worsening respiratory failure and COVID-19 pneumonitis. We discuss the current evidence of neurological involvement by SARS-COV-2 and the proposed pathophysiological mechanisms underlying these presentations.

Burning mouth syndrome (BMS) is a chronic condition presenting as intraoral burning or dysesthesia, with a high preponderance in menopausal women. This study aimed to examine the association between somatosensory dysfunction and BMS in premenopausal, early postmenopausal, and late postmenopausal patients, using a standardized Quantitative Sensory Testing (QST) protocol, and to determine the predictive value of thermal or mechanical perception by QST for detecting BMS.
