Standardized systemic treatment options are lacking for carcinoma ex pleomorphic adenoma, which is a rare and aggressive tumor primarily found in salivary glands.Here we report the case of a 63-year-old male with carcinoma ex pleomorphic adenoma of the left parotid and parapharyngeal space harboring a neurotrophic receptor tyrosine kinase (NTRK) 2 fusion who was treated with a small molecule inhibitor that targets the tropomyosin receptor kinase (TRK) proteins. To the best of our knowledge, no similar case has been described in the literature so far.
After multiple surgical resections and radiotherapy for localized cancer disease over several years, our patient again developed an increasing swelling and pain around the left ear and numbness of the left half of the face.
Magnetic resonance imaging and positron emission tomography/computed tomography scans showed tumor recurrence in the left parotid, below the left ear, and in the parapharyngeal space, as well as metastases of the lungs and cervical lymphf resistance.
Severe laryngeal edema can cause upper airway obstruction, which is fatal. Pseudoterranova, an uncommon nematode of the family Anisakidae, predominantly invades the stomach after ingestion of the nematodes in raw or undercooked marine fish. There have been a few reports of development of severe laryngeal edema caused by the nematode invading the base of the tongue.
A 69-year-old Japanese woman complained of stuffy and scratchy throat for 8 hours and reported eating sashimi, fresh slices of raw jacopever, 4 days before the first visit.
Endoscopy revealed a white-yellowish wriggling worm at the left side of the base of the tongue and severe edema of the larynx.
The worm was extracted using endoscopic forceps. The patient was hospitalized and treated with intravenous injection of an antibiotic and steroid.
The symptoms and laryngeal edema disappeared the next day. The worm was identified as a 4th-stage larva of Pseudoterranova spp based on morphologic features. selleckchem The serum Anisakis-specific IgE antibody level was high, at 38.6 UA/mL.
Clinicians should be aware of the possibility of severe laryngeal edema due to invasion by anisakid nematodes in the pharyngolaryngeal area in cases involving previous ingestion of raw or uncooked marine fish.

The clinical prognosis of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) patients is poor. Therefore, effective treatment is still a challenge at present. Moreover, little is known about the value of radiotherapy in the treatment of PTCL-NOS.
A 55-year-old male patient with eating difficulties and progressive exacerbation for 3 months was diagnosed as non-Hodgkin's lymphoma. Airway compression occurred after 2 cycles of first line treatment with cyclophosphamide-Adriamycin-vincristine-prednisone regimen, radiotherapy (48Gy/24f) was given as the second line therapy.
After radiotherapy, the patient complained that mild intermittent dysphagia still existed. Endoscopic biopsy of the upper digestive tract confirmed necrotic material and superficial squamous epithelial mucosa, suggesting esophageal stricture after radiotherapy, which was indistinguishable from tumor residue.
The patient received anti-inflammatory treatment outside the hospital and did not receive any other special treatment.
The symptoms of dysphagia disappeared and the focus showed complete response (CR). As of October 1, 2020, the patient has been diagnosed with PTCL-NOS for more than 57 months and the overall survival (OS) have not been achieved.
Radiotherapy has obvious and rapid anti-tumor effect on cyclophosphamide-Adriamycin-vincristine-prednisone refractory PTCL-NOS. At the same time, hollow organs after radiotherapy can lead to lumen stenosis and the symptoms of suspected recurrence which is difficult to distinguish only from the imaging findings.

In patients with diffuse large B-cell lymphoma, MYC combined with Bcl2 and/or Bcl6-based protein expression is called double expression lymphoma (DEL). R-DA-EPOCH program chemotherapy is typically recommended because these patients often have a poor prognosis. Although numerous factors affect survival of patients with DEL, the roles of the tumor biomarker histone methyltransferase G9a (G9a) and the lymphocyte-to-monocyte ratio (LMR) are unknown.We performed a retrospective analysis of data from 51 patients. These patients were newly diagnosed with DEL and treated with R-DA-EPOCH at Taizhou People' s Hospital and Northern Jiangsu People's Hospital between June 2014 and December 2019. Receiver operator characteristic curve results were used to calculate the LMR cutoff value. We used an immunohistochemical analysis to examine G9a expression in DEL tissues. The Kaplan-Meier method was used to determine progression-free survival (PFS) and overall survival (OS) characteristics. Cox proportional-hazards models werram chemotherapy.
Chronic low back pain (CLBP) is 1 of the common clinical diseases, and many treatment methods can only improve the symptoms of pain in the short term. Traditional Chinese sports - Baduanjin has been proven to have a positive effect on chronic low back pain. However, the quality of the research is low, the sample size is small, and safety observations are lacking. We describe the protocol of a randomized controlled trial to study the efficacy and safety of Baduanjin chronic low back pain.
This randomized, controlled, evaluator-blind, two-arm, parallel clinical trial will include 90 outpatients with chronic low back pain recruited from the First Hospital of Nanping City, Fujian Province. The patients were randomly assigned to the intervention group (Baduanjin exercise training) and the control group (not receiving any special exercise training) at a ratio of 11. Patients in the intervention group will receive Baduanjin exercise training 3 times a week for 24 weeks. The 2 groups received a 4- week follow-up observation at 24 weeks.
