xlomafota13 shared this article with you from Inoreader Artemisinin resistance: an important emerging clinical problem in tropical medicine Via International Journal of Physiology, Pathophysiology and Pharmacology Int J Physiol Pathophysiol Pharmacol. 2021 Dec 15;13(6):152-157. eCollection 2021. ABSTRACT Artemisinin is an important antimalarial drug which is originated and developed from Chinese traditional herbal regimen. At present, artemisinin is used as an antimalarial drug for treatment of drug resistant malarial infection. The effectiveness of artemisinin is clinically accepted. Hence, artemisinin is currently used as main drug for malaria treatment in many tropical countries. Artemisinin resistance is a new emerging clinical problem in tropical medicine. New mutation can result in artemisinin resistance and the resistance becomes important new emerging problem in clinical malariology. It is necessary to control of artemisinin use and searching for new effective drug against artemisinin resistant malaria. In this article, the authors summarizes on important updated information regarding artemisinin resistance. PMID:35103097 | PMC:PMC8784654 View on the web Inoreader.

Effects of oral screen exercise on orofacial and pharyngeal activity: An exploratory study using videofluoroscopy and surface electromyography in healthy adults

xlomafota13 shared this article with you from Inoreader Effects of oral screen exercise on orofacial and pharyngeal activity: An exploratory study using videofluoroscopy and surface electromyography in healthy adults Via swallowing exercises Clin Exp Dent Res. 2022 Feb 1. doi: 10.1002/cre2.538. Online ahead of print. ABSTRACT OBJECTIVE: The oral screen is a device commonly used for treatment of orofacial disorders. The objective of this exploratory study was to examine the effect of oral screen exercise on the muscle activity in the lips, submental complex, masseter muscle, and kinematic activity of the tongue base, soft palate, pharynx, and larynx in healthy adults. This was compared with the kinematic activity during a dry swallow. It was hypothesized that not only the lip musculature but also other structures in the oral and pharyngeal cavities are activated while using an oral screen device. METHOD: Ten healthy subjects used an oral screen during examination with videofluoroscopy and surface electromyography (EMG). Three different instructions for oral screen application and a dry swallow were examined. RESULTS: The lip muscles showed the highest activity during oral screen exercise. The other muscle groups were activated to a lesser degree. The pattern of activation differed between individuals. Compared with a dry swallow, the range of motion of the tongue base, posterior pharyngeal wall, and the larynx was significantly smaller during oral screen activation. No major differences were found between three different instructions. CONCLUSION: This study indicates that the lips and submental complex and, to a lesser degree, oral, pharyngeal, and laryngeal structures are activa ted with the oral screen, but the pattern of activation varied between individuals. In comparison to the activity during a dry swallow, range of motion during oral screen exercise is small. PMID:35106972 | DOI:10.1002/cre2.538 View on the web Inoreader.

An analysis of hematological, coagulation and biochemical markers in COVID-19 disease and their association with clinical severity and mortality: an Indian outlook

xlomafota13 shared this article with you from Inoreader An analysis of hematological, coagulation and biochemical markers in COVID-19 disease and their association with clinical severity and mortality: an Indian outlook Via American Journal of Blood Research Am J Blood Res. 2021 Dec 15;11(6):580-591. eCollection 2021. ABSTRACT BACKGROUND: The "cytokine storm" (CS) in COVID-19 leads to the worst stage of illness which can be controlled only with timely intervention. There is an urgent need to identify laboratory markers of disease progression for optimum allocation of resources in developing countries like India. METHODS: A cross-sectional study was conducted on 100 COVID-19 positive patients over two months. The cases were sub-classified based on disease severity into mild to moderate (n=61), severe (n=26) and very severe (n=13) and into survivors (n=85) and non-survivors (n=15) based on survivor status. These patients were tested for hematological parameters (total blood lymphocyte counts, NLR, PLR, platelet indices etc.), coagulation markers (D-dimer, fibrin degradation products (FDP), fibrinogen etc.) and biochemical markers (LDH, ferritin, IL-6, procalcitonin, hs-CRP). RESU LTS: Statistically significant differences were observed in hematological variables (ANC, NLR and ESR), coagulation parameters (D-dimer, FDP, fibrinogen and thrombin time) and biochemical markers (LDH, ferritin, IL-6, procalcitonin and hs-CRP) with regard to subcategories based of disease severity as well as survivor status. There was strong correlation between NLR, D-dimer, IL-6, procalcitonin and ferritin. IL-6 emerged as the single best marker of disease severity (AUC: 0.997, P=0.00), however procalcitonin, LDH, D-dimer, FDP and NLR could also predict severe disease with a good sensitivity and specificity. CONCLUSION: To conclude, study demonstrates a plethora of biomarkers which could be utilized to accurately identify the hyperinflammation and tissue damage reminiscent of cytokine storm in COVID-19 patients so that timely, safe, and effective therapies can be administered to prevent progression and potentially reduce mortality.

A review of neoplasms with MITF/MiT family translocations

xlomafota13 shared this article with you from Inoreader A review of neoplasms with MITF/MiT family translocations Via Cellular and Molecular Biology Histol Histopathol. 2022 Feb 2:18426. doi: 10.14670/HH-18-426. Online ahead of print. ABSTRACT Microphthalmia-associated transcription factor (MITF/MiT) family is a group of basic helix-loop-helix leucine zipper (bHLH-LZ) transcription factors including TFE3 (TFEA), TFEB, TFEC and MITF. The first renal neoplasms involving MITF family translocation were renal cell carcinomas with chromosome translocations involving ASPL-TFE3/t(X;17)(p11.23;q25) or MALAT1-TFEB/t(6;11)(p21.1;q12), and now it is known as MiT family translocation RCC in 2016 WHO classification. Translocations involving MITF family genes also are found in other tumor types, such as perivascular epithelioid cell neoplasm (PEComa), Alveolar soft part sarcoma (ASPS), epithelioid hemangioendothelioma, ossifying fibromyxoid tumor (OFMT), and clear cell tumor with melanocytic differentiation and ACTIN-MITF translocation. In this review, we summarize the features of different types of neoplasms with MITF family translocations. PMID:35107169 | DOI:10.14670/HH-18-426 View on the web Inoreader.

Complications Encountered with ETV in Infants with Congenital Hydrocephalus

xlomafota13 shared this article with you from Inoreader Complications Encountered with ETV in Infants with Congenital Hydrocephalus Via leak of cerebrospinal fluid Neurol India. 2021 Nov-Dec;69(Supplement):S520-S525. doi: 10.4103/0028-3886.332252. ABSTRACT BACKGROUND: Hydrocephalus is an abnormal excessive accumulation of cerebrospinal fluid (CSF) in the cavity and spaces of the brain. Endoscopic third ventriculostomy (ETV) has been an established treatment modality for congenital hydrocephalus. However, in very young infants, the results are challenging. In our study, we have evaluated whether ETV really offers an acceptable complication-free postoperative course. OBJECTIVE: To study the complication and mortality rate in infants having congenital hydrocephalus treated with ETV. MATERIALS AND METHODS: This is a single-center prospective study conducted at the Department of Neurosurgery, K. G. M. U, Lucknow, from January 2019 to February 2020. We studied 40 infants presenting with clinical and radiological features suggestive of congenital hydrocephalus. Follow-up was done at the first, thir d, and sixth months after discharge. RESULTS: Nineteen infants (47.5%) required a second CSF diversion procedure at 6 months of follow-up. The failure rate was significantly higher in infants less than 3 months of age (P value of 0.04). The ETV site bulge was the most frequent complication encountered in the postoperative period, occurring in 20% of the cases. Eventually, all these infants required a ventriculoperitoneal shunt; 15% developed clinical features consistent with the diagnosis of post-ETV meningitis. The ETV site CSF leak occurred in 10% of the patients. Subdural hygroma developed in 7.5% of the patients; 17.5% of the patients contributed to mortality with a mean time of expiry of 22 days post-procedure. All these deaths had multifactorial causes and could not be said as a complication or failure of ETV. CONCLUSION: We do not recommend ETV for infants less than 3 months because of a high failure rate. The ETV site bulge was the most reliable and earliest mark er of failure and a second CSF diversion surgery should be immediately considered.

Symptomatic Lingual Thyroglossal Duct Cyst in Children: A Laryngomalacia Phenotype

xlomafota13 shared this article with you from Inoreader Symptomatic Lingual Thyroglossal Duct Cyst in Children: A Laryngomalacia Phenotype Via otol rhinol Ann Otol Rhinol Laryngol. 2022 Jan 31:34894221075082. doi: 10.1177/00034894221075082. Online ahead of print. ABSTRACT OBJECTIVES: Patients with lingual thyroglossal duct cyst (TGDC) can present as symptomatic with obstructive airway and feeding difficulties. METHODS: We present 3 cases of symptomatic lingual TGDC. RESULTS: All 3 patients were diagnosed with laryngomalacia and underwent further concurrent or delayed airway intervention, in addition to cyst removal . CONCLUSIONS: We reason that there is a phenotype of laryngomalacia in the symptomatic lingual thyroglossal duct cyst patients who present with symptoms due to disruption in laryngeal anatomy rather than the cyst itself causing obstructive symptoms. Distinguishing this phenotype, especially in comparison to other pathologies such as vallecular cysts, may better allow for planning of concurrent or delayed airway procedures and overall counseling of parents.
