A painful or non-painful trigeminal nerve lesion brought on by trauma that exhibits symptoms and/or clinical evidence of trigeminal nerve dysfunction is known as painful post-traumatic trigeminal neuropathy (PTTN). In relation to this, the term post-traumatic persistent dentoalveolar pain (PDAP) is an idiopathic condition of chronic neuropathic origin that manifests as a diagnostic challenge for dental practitioners. Neuropathic pain is defined by the International Association for the Study of Pain (IASP) as "pain initiated or caused by a primary lesion or dysfunction in the nervous system." PDAP is located primarily in the teeth and jaws. This study systematically reviews how likely it is to get painful PTTN if the patient received endodontic therapy and the duration between doing root canal therapy (RCT) and getting PTTN. A systematic review was carried out using key search terms from PubMed, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) with English as the only permitted language. There were strict inclusion requirements. The 10 articles that were included showed a prevalence of an endodontic procedure anywhere from three to 48 months following post-endodontic treatment, and it mainly affects females in their mid-40s with no variation regarding the areas, whether it is in the maxilla or mandible. The lack of information about the association between RCT and PTTN led practitioners to make wrong diagnoses, which made the patient unwilling to seek further help. So, in this review, we identified some visible characteristics that can help in that process.

Pentazocine, a synthetic opioid with partial agonist and antagonist activity administered by parenteral injection, was used clinically in the 1970s. Dermatologic complications at injection sites were reported soon after its introduction. These complications are thought to be underreported. Many well-documented cases describe the development of fibrosis and calcinosis at the site of parenteral pentazocine injections, but few reports document management or successful treatment of the long-term sequelae of these manifestations.

Vitamin D delivered transdermally may suppress hyperactivity in nociceptor pain receptors and alter pain intensity, offering a useful addition to localised pain management in varying clinical settings. Currently, little is known about long-term usage of continuous-release vitamin D patches.

Migraine is one of the most common neurological diseases. The pathophysiology of migraine has not yet been fully elucidated. There is increasing evidence supporting the relationship between oxidative stress and migraine.

Paeoniflorin has been traditionally used to treat pain and immunologic derangement in China. However, its detailed mechanism remains to be illuminated. We investigated the mechanism by which paeoniflorin alleviates the inflammatory response in a mouse model of irritable bowel syndrome with predominant diarrhea (IBS-D). C57BL/6 wild type (WT) and miR-29a knockout (KO) mice were randomly divided into control, model, rifaximin, and paeoniflorin groups (n = 7). IBS-D model was induced by single intracolonic instillation of 0.1 mL trinitro-benzene-sulfonic acid (TNBS, 50 mg/mL) combined with restraint stress for seven consecutive days. The treatment groups received rifaximin (100 mg/kg) and paeoniflorin (50 mg/kg) via intragastric administration for seven days, respectively. The results showed that the fecal water content, fecal pellet output, visceral sensitivity, and histopathological score after paeoniflorin treatment were lower than those of the model group in both WT and miR-29a KO mice (P < 0.05). In both lineage mice, damage was observed in the colon tissues of model group, while paeoniflorin treatment partially ameliorated the tissue damage. Serum levels of DAO, DLA, IL-1β, IL-18, TNF-α, and MPO were decreased after paeoniflorin treatment (P < 0.05), with miR-29a KO mice in a lower level compared with that of WT mice. RT-PCR showed that the relative expression of miR-29a, NF-κB (p65), NLRP3, ASC, caspase-1, IL-1β, and TNF-α was downregulated while NKRF was upregulated after paeoniflorin treatment (P < 0.05). Immunohistochemistry showed that intestinal epithelial protein levels of NLRP3, ASC, and caspase-1 decreased while those of Claudin-1 and ZO-1 increased in the paeoniflorin treatment group (P < 0.05). In general, compared with WT mice, NLRP3 inflammasome pathway targets was in much lower expression level than miR-29a KO mice. In conclusion, paeoniflorin could inhibit abnormal activation of the NLRP3 inflammasome pathway by inhibiting miR-29a in IBS-D, thereby relieving the inflammatory response of the intestinal mucosa and reconstructing the intestinal epithelial barrier.

and importance: Cannabinoid, a widely used recreational drug worldwide. In Nepal, it is found easily and has multiple used as well as misused as a psychoactive substance. Despite having anti emetic property of Marijuana, chronic use of the substance can lead to cyclic vomiting syndrome due to effect in central nervous system and gastrointestinal system.

 The spinal column is one of the most prevalent regions for metastasis, with an increasing frequency of spinal metastases. Spinal cord metastatic tumor damages the vertebral body, weakens the spinal support, and exerts mass effect on the spinal cord. Overzealous surgical intervention does not provide any additional benefit in most of the spinal metastasis due to shorter life expectancy. The principal goal of this study is to analyze the outcome of various surgical treatments offered to patients with metastatic spinal cord compression (MSCC).  Retrospective cohort study including all patients that underwent surgical intervention for MSCC from March 2013 to March 2020.  A total of 198 patients were included, 113 males and 85 females; the mean age was 62 years. The most common primary cancer was prostate (21.71%) followed by hematological (20.07%) and lung (16.66%). At 6-month postsurgery, 68.68% of patients were Frankel grade D or E (vs. 23.23% preoperatively), 16.6% were grade C (vs 57% preoperatively), and 14.64% were grade A or B (vs. 19.69% preoperatively). Pain on numeric rating scale was decreased from 6.38 ± 3.08 to 3.39 ± 0.73 at 24 hours postsurgery and 1.94 ± 0.67 at 6 months.  This study found that the majority of patients, undergoing minimally invasive spinal stabilization and decompression for metastatic spinal tumors, have better quality of life, analgesia, and mobility. In conclusion, treatment for spinal metastases should be individualized and a multidisciplinary approach is needed.

Design This study is a double-blind, single-centre, split-mouth, prospective randomised control trial. In total, 48 patients had bilateral third molars removed during two separate operations at least 21 days apart by the same maxillofacial surgeon. During the control operation, the tooth was irrigated with saline at 25°C. During the test operation, patients were randomised to tooth irrigation with saline at either 10°C (n = 24) or 4°C (n = 24). Local anaesthetic, flap design, burr design and sutures remained consistent throughout. Patients were prescribed amoxicillin, chlorhexidine and were advised to take paracetamol as needed. The patients remained blinded to which test group they were randomised to and to the order of the control or test operations performed. Participants self-recorded analgesia use and post-operative pain daily for seven days using a visual analogue scale (VAS). A second maxillofacial surgeon examined patients on days one, three and seven. Facial swelling was assessed by measuring the distance between various soft tissue points compared to pre-operative levels. Trismus was determined by measuring maximum inter-incisal opening compared to pre-operative levels.Case selection In total, 28 female and 20 male medically fit adult patients with a mean age of 24.6 ± 3.8 with bilateral mandibular asymptomatic third molar teeth were selected. Second molars with periodontal probing depths >4 mm or impacted third molars associated with cysts or tumours were excluded. Patients had no antibiotic prescription in the preceding month nor analgesic consumption in the 12 hours before surgery.Data analysis The Shapiro-Wilk test was used to evaluate if the sample fit a normal distribution. Relationships between the categorical variables of the groups was tested using chi-square statistics. Data comparisons were examined with the Duncan, Kriskal-Wallis, Dunn and Friedman test (p <0.05).Results The median duration of the control and test group operations were similar (p = 0.051). Test group patients reported lower pain VAS values and consumed less analgesics compared to the control groups (p = 0.001), with the lowest values seen in the 4°C group (p <0.001). A greater decrease in trismus levels was also seen on day three and seven in the test groups (p <0.001) compared to the control group (p = 0.07). Swelling was greatest in the control group (p <0.001) and reduced on day seven (p <0.001) in all groups. While trismus and swelling values were lower in the 10°C test group compared to the control (p <0.001), the lowest values of these parameters at all time points was in the 4°C group (p <0.001).Conclusions Early complications following third molar removal include facial swelling, trismus and pain. In this study, intraoperative cooled saline irrigation to 4°C and 10°C was more effective than saline irrigation at 25°C in reducing the intensity of these conditions.

(FPPFC) was developed to assess quality of physician-family end-of-life communication in nursing homes. However, its validity has been tested only in the USA and the Netherlands. The aim of this paper is to evaluate the FPPFC construct validity and its reliability, as well as the psychometric characteristics of the items comprising the scale. Data were collected in cross-sectional study in Belgium, Finland, Italy, the Netherlands and Poland. The factorial structure was tested in confirmatory factor analysis. Item parameters were obtained using an item response theory model. Participants were 737 relatives of nursing home residents who died up to 3 months prior to the study. In general, the FPPFC scale proved to be a unidimensional and reliable measure of the perceived quality of physician-family communication in nursing home settings in all five countries. Nevertheless, we found unsatisfactory fit to the data with a confirmatory model. An item that referred to advance care planning performed less well in Poland and Italy than in the Northern European countries. In the item analysis, we found that with no loss of reliability and with increased coherency of the item content across countries, the full 7-item version can be shortened to a 4-item version, which may be more appropriate for international studies. Therefore, we recommend use of the brief 4-item FPPFC version by nursing home managers and professionals as an evaluation tool, and by researchers for their studies as these four items confer the same meaning across countries.

Medically unexplained dermatologic symptoms, such as pruritus, numbness and burning are known as somatization. These cutaneous symptoms can be very difficult to treat because of an absence of an objective explanation and they may not fit neatly into any known dermatological or psychiatric condition. These disorders are more commonly encountered in primary care and in dermatology, rather than in psychiatry. Certain skin disorders, for example, pruritus, could be a manifestation of somatization and others may predispose to somatic symptoms, for example, atopic dermatitis and psoriasis. Although there has been increasing research in the interconnection between psychiatry and dermatology, psychodermatology is a relatively new crossover discipline in clinical practice and recognition of psychodermatological conditions, such as cutaneous somatic disorders, can be difficult. Somatization may occur with or without the existence of a dermatological disease. When a dermatological disorder is present, somatization should be considered when the patient is worrying too much about their skin, spending too much time and energy on it and especially if the patient also complains of many non-cutaneous symptoms. Purely cutaneous somatic conditions include for example, the genital pain syndromes or Gardner-Diamond syndrome, characterized by unexplained bruising, which usually affects women. Effective management tools may include mindfulness therapies, pharmacotherapy with selective serotonin reuptake inhibitors, tricyclic antidepressants and cognitive conduct therapy. Electroconvulsive therapy can also be considered in extremely rare cases for treatment of severe somatization on a background of mood disorders. This paper discusses somatization, its relationship to immunodermatoses and its relevance to clinical practice.
