Background: Temporomandibular Disorder (TMD) pain attributed to myalgia is a common condition and patients should get advice on the best treatment option. Objectives: The aim was to evaluate the effect of two different exercise programs, or bite splint therapy, respectively, in patients with chronic frequent primary myofascial orofacial pain. Methods: The study was a randomized clinical trial including patients fulfilling criteria of chronic frequent primary myofascial orofacial pain with a reported pain intensity of ≥ 4 on a numerical rating scale (0-10). Ninety subjects were randomized to either bite splint, home exercises, or a supervised exercise program. Two examiners blinded to the treatment modality examined the same subject at baseline and a 3-month follow-up. Non-parametric statistical methods were applied for the outcome of treatment in intended-to-treat analyses. A P-value <0.05 was considered statistically significant. Results: The pain severity index was significantly reduced (p < 0.001) in all treatment groups. Jaw opening capacity improved significantly (p < 0.05) for those randomized to bite splint and for those in the home exercise program. About 70% of the participants reported improvement in their TMD pain severity with no significant difference between treatments. Both exercise groups improved in jaw function at the 3-month follow-up compared to baseline. Those who had a bite splint reported significantly more improvement in their headaches compared to those in the exercise programs. Conclusion: Jaw exercise programs and bite splint treatments had similar positive effects on TMD pain severity attributed to myalgia after 3 months.

Background: Drosophila models of amyotrophic lateral sclerosis (ALS) have been widely used in understanding molecular mechanisms of ALS pathogenesis as well as discovering potential targets for therapeutic drugs. Mutations in the copper/zinc superoxide dismutase (SOD1) cause ALS by gain of toxic functions and induce toxicity in fly motor neurons. Results: In this study, we have determined that human carbonic anhydrase I (CA1) can alleviate mutant SOD1-induced motor neuron toxicity in the transgenic fly model of ALS. Interestingly, we found that motor neuron expression of CA1 could independently induce locomotion defect as well as decreasing the survival rate. In addition, CA1-induced toxicity in motor neurons is anhydrase activity-dependent. Mechanistically, we identified that both SOD1- and CA1-induced toxicity involve the activation of eIF2α in the ER stress response pathway. Downstream activation of the JNK pathway has also been implicated in the induced toxicity. Conclusion: Our results have confirmed that SOD1-induced toxicity in fly motor neuron also involves endoplasmic reticulum (ER) stress pathway. More importantly, we have discovered a new cellular role that CA1 plays by antagonizing mutant SOD1-induced toxicity in motor neurons involving the ER stress pathway. Such information can be potentially useful for further understanding disease mechanisms and developing therapeutic targets for ALS. 

Background: The prevalence of musculoskeletal disorders is particularly high among garment workers, which poses a serious occupational health hazard. This issue is not taken seriously as an important issue in low-income countries like Bangladesh.Aim: Determine the prevalence of musculoskeletal conditions (MSDs) among garment workers in nine body regions and explore the relationship between MSDs and the general characteristics of the participants.Materials and methods: A cross-sectional study including 383 garment workers was done. A structured questionnaire (Standardized Nordic Musculoskeletal) was used. Results: The most common form of pain in the last year was lower back pain. Nine anatomical locations were studied, and workers most commonly experienced problems with their lower back (45.4%), upper back (36.6%), and knees (33.2%). Workers reported having more trouble in the knee (31.9%), upper back (35.0%), and lower back (43.9%) regions over the past seven days. In the past year and the last seven days, shoulder injuries were the least common. Conclusion: MSDs are widespread among garment industry employees. The back condition is the most commonly affected. The development of MSD is directly correlated with age and work experience.

Related the extremely transmittable abilities of SARS-CoV-2,a harmonious virus to the bat CoV, gets transmitted by three principal processes-- the inhalation of droplets from the SARS-CoV-2 infected person, contacting to the person, and by the surfaces and materials defiled with the virus. Whereupon bat Coronavirus is mostly like the pandemic causing virus SARS-CoV-2, bats are often deliberated and figured out as a possible primary host although no intermediate has not been defined yet in the wherewithal of transmission. The Spike Glycoprotein plays an important role in the case of penetration with the assistance of the ACE2 receptor and the Receptor Binding Domain. In the human body, infiltrating the nucleic acid into host cells, SARS-CoV-2 attacks one cell and one by one into the whole human body; therefore, infected cases are found symptomatic and asymptomatic considering the immune power. Patients with cardiovascular disease or diabetes proceed with their treatment with ACE2 often; therefore, there might be a high chance of getting infected. Whereas the SARS-CoV-2 infects the blood and then lungs, Antigens improvement can be better in order to avoid high-complicated effects. Currently, no vaccination or no accurate cure and treatment has not been defined. An explanation with analysis on SARS-CoV-2 has been performed from the aspect of virology, immunology and molecular biology. Several relevant figures have been included hereby in order to a better understanding of the very concept.

Endotheliosis, thrombotic microangiopathy and complement system over activation have been described as pathologic features of tissue damage in the setting of coronavirus disease. Interestingly, complement-mediated cell injury is also a typical feature of atypical Hemolytic Uremic Syndrome. Indeed, a growing body of literature has described a higher risk of microangiopathy recurrence, in aHUS patients who test positive for SARS-CoV-2. The correct clinical and therapeutic management patients with a history of HUS and SARS-CoV-2 infection is not well established.We report a case of SARS-CoV-2 infection in an aHUS patient who did not develop a recurrence of the disease and that was successfully treated with convalescent immune plasma therapy.

Today, Mexico has more than 130 million inhabitants; 85 millions of them are adults of 20 or more years old. The population pyramid is still one of base wider and this base corresponds to adults younger than 54 years old. Despite predictions made 20 years ago, about a transformation of the population pyramid shape to a mushroom shape as a consequence of more life expected and adult population growth; this change has not been occurred. Hypertension has become the biggest challenge of noncommunicable chronic diseases to public health in Mexico. Around 30% of adult Mexican population has hypertension; 75% of them have less than 54 years old (in productive age); 40% of them are unaware but only 50% of aware hypertensive population takes drugs and, 50% of them are controlled (< 140/90 mmHg). Cardiovascular risk factors including hypertension, dyslipidemia, obesity, and diabetes often cohabit in the same person and are magnified one to another in terms of common pathophysiological pathways. Atherosclerosis, arrhythmias, stroke and heart failure are common and are the final pathologic end-points and explains why cardiovascular diseases occupy first place in mortality in Mexico and worldwide. The costs of care for these diseases are billionaires and if we do not generate appropriate strategies, their global impact can become a high threat to social development of the country. The life style like nutrition, sports habits of the Mexicans must be emphasized; there is poor education about this crucial topic. This position paper is focused on the principal controversies and strategies to be developed by all, government, society, physicians, nurses, patients and all people related with healthcare of hypertension, in order to confront this huge public health problem in Mexico.

Lipoma is a benign mesenchymal tumor with a thirteen percent incidence in head and neck region. Posterior triangle is the most common location while anterior neck lipoma is a rare one. Giant lipomas >10cm have been reported in different parts of the body but rarely in the anterior neck. Giant lipomas of the neck can present as a cosmetic disfigurement or can produce pressure symptoms. Most lipomas do not pose any difficulty in diagnosis. Surgical excision remains the treatment of choice. We here present a case of giant anterior neck lipoma.

Background: Cerebral small vessel disease and extracranial atherosclerotic carotid disease are manifestations of silent cerebrovascular disease (CVD). Information on these two pathologies in hypertensive population with low cardiovascular risk (CVR) is scarce. Objective: To explore frequency and characteristics of silent CVD in hypertensive adults and cognitive repercussion of these alterations. Methods: 39 hypertensive patients (mean age: 53.5 years) were studied. Cerebral magnetic resonance imaging (3T), doppler ultrasound of the carotid artery and neuropsychological studies were obtained. Results: 79% of patients presented white matter lesions (WML), 18% showed only cerebral atrophy and/or enlarged perivascular spaces, 60% presented hyperplasia of intimal media complex (IMC) and/or atheroma plaques. In women, a significant correlation was observed between IMC thickness and bifrontal index, and WML was greater in patients with carotid plaques. A non-significant decrease in neuropsychological performance was observed in the groups of patients with intra and/or extracerebral injury and a negative correlation with the bifrontal index in men was found. Conclusion: Frequency of intra and extracerebral silent CVD was high in hypertensive adults with low to moderate CVR. WML and brain atrophy were partially related with carotid lesions. Age significantly influenced the appearance of intra and extracerebral lesions. Cognitive performance did not decrease significantly due to the presence of these lesions.

Granulomatosis with polyangiitis (GPA), a form of ANCA-associated vasculitis (AAV), is a rare disease with an often-occult presentation. It is more common in 4th and 5th decades of life but can be seen in all ages. This case report details a 76-year-old female presenting with abdominal pain, generalized weakness, and malaise, who was found to have pulmonary nodules on chest imaging. Biopsy of the lung nodule showed organizing pneumonia. Initially, antibiotics were used to treat the patient. However, she developed acute renal failure a few days after presentation and found to have positive serum C-ANCA as well as elevated ANCA-PR3 serologies. A subsequent kidney biopsy demonstrated pauci-immune necrotizing and crescentic glomerulonephritis that was consistent with GPA and the patient was started immediately on combination immunosuppressive therapy, plasmapheresis, and hemodialysis. GPA’s clinical and radiological presentation can mimic other common conditions such as pneumonia, malignancy, bacterial sinusitis, pulmonary tuberculosis, sarcoidosis, and urinary tract infection. Because of this, a high level of suspicion is required for early diagnosis and treatment to alter the high mortality rate in this disease entity. All forms of ANCA-associated vasculitis (AAV) should be in the differential diagnosis for all patients presenting with multiorgan system involvement particularly in individuals with pulmonary and renal manifesations.

The lymphatic system consists of small non-contractile lymph vessels which collect fluid from the interstitial space and carry it to the major contractile lymphatic vessels with valves that maintain a unidirectional flow to the lymph nodes and is responsible for returning proteins, lipids and water from the interstitium to the venous system near the junction of the subclavian vein and internal jugular vein on both sides. Lymphedema would be the result of the failure of transport with the further accumulation of fluid rich in protein at the interstitium, especially in limbs. Primary lymphedema, which affects 1.15 / 100000 children (especially pre-pubescent girls), not always clinically evident at birth, is a genetic disorder that represents many different subsets of phenotypes: congenital or congenital lymphangiectasia, congenital trofoedema family or Meige, congenital amniotic band and essence or idiopathic. The most common form of presentation is due to congenital absence or abnormality of the lymphatic tissue caused by a genetic mutation of the genes responsible for the development of lymphatic vessels that is characterized by the difficulty of draining lymph vessels. This genetic alteration may be sporadic or inherited.
