Clinically, methadone is most known for its use in the treatment of opioid maintenance therapy. However, methadone's pharmacological profile makes it an excellent analgesic that can enhance acute and chronic pain management. It is a potent μ-receptor agonist with a longer elimination half-life than most clinically used opioids. In addition, methadone inhibits serotonin and norepinephrine uptake, and it is an N-methyl-D-aspartate antagonist. These distinct analgesic pathways mediate hyperalgesic, allodynic, and neuropathic pain. Its unique analgesic properties provide several essential benefits in perioperative use, neuropathic pain, cancer, and noncancer pain. Despite these proven clinical utilities, methadone has not been used widely to treat acute and chronic pain in opioid naïve patients. This article describes the unique pharmacology of methadone and provides emerging evidence to support its application in acute and chronic pain management. Pain management options and guidelines for surgical patients on methadone are discussed as well.

Epidural anesthesia is usually combined with general anesthesia (GA) for children undergoing sub-umbilical surgery and GA in children is associated with a potential for respiratory events. Aiming to reduce airway manipulation and the use of GA drugs, we designed a study of transvesical Cohen ureteteric reimplantion under epidural anesthesia in sedated, spontaneously breathing children.

In people in the chronic phase of Guillain-Barré syndrome (GBS), how much more does a supervised, individualised exercise program improve functional independence with activities of daily living than a home-based exercise program? How do the two exercise programs compare regarding their effects on muscle strength, fatigue, pain and quality of life?

Introduction Colloid cysts are relatively uncommon lesions in the pediatric population. The xanthogranulomatous (XG) variant is a very rare with less than 30 reported cases. Case Report In this report the patient was a 13-year-old boy who presented with transient epsiodes of headache with blurring of vision. His MRI brain showed a T2 hyperintense well-defined cystic lesion, with an eccentrically located T2 hypointense partially enhancing nodule, at the foramen of Monro. He underwent middle frontal gyrus transcortial, transchoroidal gross total excision of the cyst. The histopathology of the lesion revealed a XG colloid cyst. Patient recovered well from the procedure and was relieved of the symptoms. Conclusion XG colloid cyst may present with altered radiological features compared to the normal variant. This can pose a diagnostic dilemma and it is important to differentiate it from a craniopharyngioma or a parasitic cyst, as in our case. When considered pre-operatively, surgeons should be conscious to review their surgical strategies. Stereotactic aspiration of the XG cyst should be avoided as contents are thicker and heterogenous than the usual. The spillage of cyst contents should be prevented. Also, the XG cysts are likely to have a poor cyst-fornix or -choroid plexus interface due to inflammation limiting complete resection.

To evaluate patterns of cannabis use in patients with cutaneous lymphoma (CL), as well as the association between cannabis use and itch specifically.

The aim of this study was to assess the efficacy and adverse effects of methadone when used as first-line therapy in patients that are either receiving low doses of opioids or none.

An 11-year-old boy who presented with headache and progressive right-sided weakness exhibited cortical swelling in the parafalcine area of both frontoparietal high convexity and splenium portion of corpus callosum on brain MRI. This suggested the possibility of encephalopathy, but required differential diagnosis from brain tumor. 18F-FET (O-(2-[18F]fluoroethyl)-l-tyrosine) PET/CT identified increased uptake along the parafalcine area of the frontoparietal lobes and the splenium portion of the corpus callosum. The relatively low target-to-background ratios were more indicative of inflammatory changes such as demyelinating disease. The patient recovered after empirical steroid and immunoglobulin treatment. Clinically, the patient was diagnosed with acute disseminated encephalomyelitis.

Myocarditis has been discovered to be a significant complication of coronavirus disease 2019 (COVID-19), a condition caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. COVID-19 myocarditis seems to have distinct inflammatory characteristics, which make it unique to other viral etiologies. The incidence of COVID-19 myocarditis is still not clear as a wide range of figures have been quoted in the literature; however, it seems that the risk of developing myocarditis increases with more severe infection. Furthermore, the administration of the mRNA COVID-19 vaccine has been associated with the development of myocarditis, particularly after the second dose. COVID-19 myocarditis has a wide variety of presentations, ranging from dyspnea and chest pain to acute heart failure and possibly death. It is important to catch any cases of myocarditis, particularly those presenting with fulminant myocarditis which can be characterized by signs of heart failure and arrythmias. Initial work up for suspected myocarditis should include serial troponins and electrocardiograms. If myocardial damage is detected in these tests, further screening should be carried out. Cardiac magnetic resonance imagining and endomyocardial biopsy are the most useful tests for myocarditis. Treatment for COVID-19 myocarditis is still controversial; however, the use of intravenous immunoglobulins and corticosteroids in combination may be effective, particularly in cases of fulminant myocarditis. Overall, the incidence of COVID-19 myocarditis requires further research, while the use of intravenous immunoglobulins and corticosteroids in conjunction requires large randomized controlled trials to determine their efficacy.

Intracranial growing teratoma syndrome is a rare phenomenon characterized by enlargement of a germ cell tumor during or after adjuvant therapy despite normalization of tumor markers.1,2 It has been suggested that chemotherapy acts on the nonteratomatous components or induces differentiation of the immature germ cells to mature teratomatous phenotype.3 An 8-year-old boy presented with headache, emesis, and blurry vision. Neuroimaging revealed hydrocephalus with multiple central nervous system masses: pineal gland, suprasellar region, and spine (T8). Elevated serum and cerebrospinal fluid levels of alpha-fetoprotein and beta-human chorionic gonadotropin were found. A ventriculoperitoneal shunt was placed. Despite chemotherapy and decreasing tumor markers, the pineal mass rapidly enlarged, and the patient became somnolent. He underwent microsurgical resection with the diagnosis of mixed germ cell tumor. During his second chemotherapy cycle, the patient endorsed worsening vision and panhypopituitarism. Imaging demonstrated enlargement and honeycomb appearance of the suprasellar mass. The patient and family consented to the procedure, and an endoscopic endonasal approach was performed to access the retroinfundibular region. Removal of the nonfunctional pituitary gland and dorsum sellae was performed. Careful dissection of the tumor from the optic apparatus, hypothalamus, and perforating arteries allowed total resection. Reconstruction with fascia lata and nasoseptal flap was performed. Mature teratoma was found histologically. Postoperative course was complicated by flap hemorrhage resolved by surgical revision. Postoperative imaging showed complete resection. The patient was discharged without other complications and was making excellent recovery. To the best of our knowledge, this is the first reported case of hypothalamic intracranial growing teratoma syndrome successfully treated using an endoscopic endonasal approach.

Behavioral interventions have been used with breast cancer survivors (BCS) in cancer pain management and post-treatment quality of life (QOL) studies. We studied the effects of an anti-inflammatory dietary intervention on QOL in BCS.
