ABSTRACT OBJECTIVE: To demonstrate our experience in treating pyriform fossa sinus tracts (PFST) using a novel technique of endoscopic cauterisation of the pyriform fossa sinus opening combined with injection of sodium carboxymethylcellulose gel (VoiceGel) lateral to the tract to encourage tight closure. METHODS: Over a 48-month period, we used this technique on 11 patients who were diagnosed with PFST at BC Children's Hospital, a tertiary paediatric centre in Vancouver, BC, Canada. RESULTS: The 11 patients included 8 males and 3 females, and mean age at presentation was 69 months (range 22-108 months). Mean time from beginning of symptoms till diagnosis was 15 months (range 12-22 months). Ten PFST were on the left side of the neck and one on the right. Nine patients presented with recurrent neck infections and two had suppurative thyroiditis. All p atients had endoscopic cauterisation of their PFST opening combined with injection of carboxymethylcellulose lateral to the sinus tract to cause tract collapse. Mean follow up was 15.8 months (range 8-24). All patients are asymptomatic without recurrence at the last follow-up visit. No post-operative complications were reported. CONCLUSIONS: Endoscopic management of paediatric PFST combined with the injection of sodium carboxymethylcellulose gel lateral to the sinus tract appears to be a safe and effective treatment option for PFST.

The 5‐HT1A receptor agonist, 8‐OH‐DPAT, Attenuates Long‐Lasting Pain in Imiquimod‐Induced Psoriasis in Mice.

xlomafota13 shared this article with you from Inoreader The 5‐HT1A receptor agonist, 8‐OH‐DPAT, Attenuates Long‐Lasting Pain in Imiquimod‐Induced Psoriasis in Mice. Via Experimental Dermatology ABSTRACT Psoriasis pain is a common symptom underestimated and rarely evaluated in psoriasis clinical trials. This work aimed to investigate if the development of secondary chronic allodynia and hyperalgesia in the imiquimod (IMQ)-induced psoriasis mice model could be modulated by anti-inflammatory agents and compound 48/80 (C48/80) and to determine whether the activation of 5-HT1A receptor modulates these nociceptive behaviors. C57BL/6 male mice were treated with 5% IMQ for 7 days. The paw withdrawal responses to von Frey filaments (10 and 250 mN) were used to assess the allodynia and hyperalgesia. Nociceptive behaviors were also evaluated using ketorolac 15 mg/kg s.c; adalimumab 10 mg/kg s.c., and C48/80 10 mg/kg i.p. Then, the serum serotonin and the impact of 8-OH-DPAT (1 mg/kg s.c), a 5-HT1A receptor agonist, on long-lasting pain were examined. Mice receiving IMQ showed enhanced nociception, which decreased with all tested compounds. The serum serotonin in the IM Q-group showed a significant decrease (947.042 ng/ml) regarding the control group (1143.68 ng/ml). The pre-treatment with 8-OH-DPAT alleviated pain-related behaviors. These results suggest that the long-lasting pain resulting from psoriasis inflammation is also associated with the serotonergic system. The 5-HT1A receptor should be further explored as a potential therapeutic target for psoriasis pain modulation. View on the web Inoreader. Take back control of your news feed.

Do epidermal keratinocytes have sensory and information processing systems?

xlomafota13 shared this article with you from Inoreader Do epidermal keratinocytes have sensory and information processing systems? Via Experimental Dermatology Abstract It was long considered that the role of epidermal keratinocytes is solely to construct a water-impermeable protective membrane, the stratum corneum, at the uppermost layer of the skin. However, in the last two decades, it has been found that keratinocytes contain multiple sensory systems that detect environmental changes, including mechanical stimuli, sound, visible radiation, electric fields, magnetic fields, temperature and chemical stimuli, and also a variety of receptor molecules associated with olfactory or taste sensation. Moreover, neurotransmitters and their receptors that play crucial roles in the brain are functionally expressed in keratinocytes. Recent studies have demonstrated that excitation of keratinocytes can induce sensory perception in the brain. Here, we review the sensory and information processing capabilities of keratinocytes. We discuss the possibility that epidermal keratinocytes might represent the earliest stage in the development of the brain during the evolution of vertebrates. View on the web Inoreader.

Engineering Functional Skin Constructs: A Quantitative Comparison of Three‐Dimensional Bioprinting with Traditional Methods

xlomafota13 shared this article with you from Inoreader Engineering Functional Skin Constructs: A Quantitative Comparison of Three‐Dimensional Bioprinting with Traditional Methods Via Experimental Dermatology Abstract Tissue engineering has been successful in reproducing human skin equivalents while incorporating new approaches such as three-dimensional (3D) bioprinting. The latter method offers a plethora of advantages including increased production scale, ability to incorporate multiple cell types, and printing on demand. However, the quality of printed skin equivalents compared to those developed manually has never been assessed. To leverage the benefits of this method, it is imperative that 3D printed skin should be structurally and functionally similar to real human skin. Here, we developed four bilayered human skin epidermal-dermal equivalents: non-printed dermis and epidermis (NN), printed dermis and epidermis (PP), printed epidermis and non-printed dermis (PN), and non-printed epidermis and printed dermis (NP). The effects of printing induced shear stress [0.025 kPa (epidermis); 0.049 kPa (dermis)] were characterized both at the cellular and at the tissue level. At cellular level, no st atistically significant differences in keratinocyte colony forming efficiency (CFE) (p=0.1641), was observed. In the case of fibroblasts, no significant differences in the cell alignment index (p<0.1717), and their ability to contract collagen gel (p=0.851) were detected. At the tissue levels, all the four skin equivalents were characterized using histological and immunohistochemical analysis with no significant differences found in either epidermal basal cell count, thickness of viable epidermis, and relative intensity of filaggrin and claudin-1. Our results demonstrated that 3D printing can achieve the same high-quality skin constructs as have been developed traditionally, thus opening new avenues for numerous high-throughput industrial and clinical applications.

The importance of the patient's perspective in function-sparing parotid surgery for benign neoplasms: clinical reappraisal

xlomafota13 shared this article with you from Inoreader The importance of the patient's perspective in function-sparing parotid surgery for benign neoplasms: clinical reappraisal Via Acta Otorhinolaryngol Ital Acta Otorhinolaryngol Ital. 2021 Oct;41(5):410-418. doi: 10.14639/0392-100X-N1463. ABSTRACT OBJECTIVE: Function-sparing surgery is the cornerstone for the treatment of benign parotid neoplasms. We assessed the incidences and determinants of the main postoperative complications, reappraising their influence on the patient's quality of life (QoL). METHODS: Patients who underwent parotid surgery for benign neoplasms were reviewed (2016-2019). Parotidectomy Outcome Invento ry-8 (POI-8) and condition-specific questionnaires were used to investigate the patient's perspective. RESULTS: We enrolled 211 patients. Preservation of the posterior branch of the great auricular nerve (GAN) seemed to reduce early dysfunction (87% vs 96%, p = 0.053), but not the late one. Deep lobe dissection and resection of more than one parotid segment favoured first bite syndrome (FBS) and Frey's syndrome (FS), respectively (16% vs 3%, p = 0.003; 37% vs 15%, p = 0.003). Neither GAN impairment, FBS, nor FS influenced patient QoL. Facial weakness affected 19 patients (9%), being more likely after total parotidectomy (23% vs 7%, p = 0.034). According to POI-8, QoL was mainly jeopardised by fear of revision surgery, especially in females (p = 0.005) and those experiencing early complications (p = 0.004). CONCLUSIONS: Reappraisal of the patient's perspective after functional parotid surg ery is fundamental to tailor preoperative counselling.

Recurrence of benign paroxysmal positional vertigo: experience in 3042 patients

xlomafota13 shared this article with you from Inoreader Recurrence of benign paroxysmal positional vertigo: experience in 3042 patients Via Acta Otorhinolaryngol Ital Acta Otorhinolaryngol Ital. 2021 Oct;41(5):461-466. doi: 10.14639/0392-100X-N1233. ABSTRACT OBJECTIVES: Benign paroxysmal positional vertigo (BPPV) is a disorder of the inner ear with a high rate of recurrence. Vascular disorders, migraine and autoimmune disorders have been considered facilitating factors for relapsing episodes. Our aim was to assess the role of vascular disorders, migraine and anti-thyroid antibodies in patients with recurrences. METHODS: We retrospec tively analysed records of 3042 patients treated for BPPV without other lifetime vertigo. Clinical data included previous vascular disorders of the central nervous system, heart disorders, migraine and recent head trauma. The presence of anti-thyroid autoantibodies was assessed in all patients. RESULTS: Mean age of the first BPPV was 52.8 ± 14.5 years; there were 2339 females (76.9%), while 2048 (67.3%) of patients presented recurrences within two years of follow-up. Previous disorders of the central nervous system, presence of anti-thyroid antibodies, head trauma and migraine showed an association with recurrences. Above all, in subjects having the first BPPV while aged between 40 and 60 years, anti-thyroid antibodies were predictive for recurrences. CONCLUSIONS: Our data are consistent with the hypothesis that anti-thyroid autoantibodies may play a role in recurrences in subjects with initial manifestations between 40 and 60 years.
