Scalp pruritus is a frequent problem encountered in dermatological practice. This disorder is caused by various underlying diseases and is a diagnostic and therapeutic challenge. Scalp pruritus may be localized to the scalp or extended to other body areas. It is sometimes not only associated with skin diseases or specific skin changes, but also associated with lesions secondary to rubbing or scratching. Moreover, scalp pruritus may be difficult to diagnose and manage and may have a great impact on the quality of life of patients. It can be classified as dermatologic, neuropathic, systemic, and psychogenic scalp pruritus based on the potential underlying disease. A thorough evaluation of patients presenting with scalp pruritus is important. Taking history and performing physical examination and further investigations are essential for diagnosis. Therapeutic strategy comprises removal of the aggravating factors and appropriate treatment of the underlying condition. All treatments should be performed considering an individual approach. This review article focuses on the understanding of the pathophysiology and the diagnostic and therapeutic management of scalp pruritus.

Background: Weaning from tracheostomy has implications in management, quality of life, and costs of ventilated patients. Furthermore, endotracheal cannula removing needs further studies. Aim of this study was the validation of a protocol for weaning from tracheostomy and evaluation of predictor factors of decannulation. Methods: Medical records of 48 patients were retrospectively evaluated. Patients were decannulated in agreement with a decannulation protocol based on the evaluation of clinical stability, expiratory muscle strength, presence of tracheal stenosis/granulomas, deglutition function, partial pressure of CO2, and PaO2/FiO2 ratio. These variables, together with underlying disease, blood gas analysis parameters, time elapsed with cannula, comordibity, Barthel index, and the condition of ventilation, were evaluated in a logistic model as predictors of decannulation. Results: 63 % of patients were successfully decannulated in agreement with our protocol and no one needed to be re-cannulated. Three variables were significantly associated with the decannulation: no pulmonary underlying diseases (OR = 7.12; 95 % CI 1.2–42.2), no mechanical ventilation (OR = 9.55; 95 % CI 2.1–44.2) and period of tracheostomy ≤10 weeks (OR = 6.5; 95 % CI 1.6–27.5). Conclusions: The positive course of decannulated patients supports the suitability of the weaning protocol we propose here. The strong predictive role of three clinical variables gives premise for new studies testing simpler decannulation protocols.

Gastro Esophageal Reflux Disorders(GERD) are group of conditions where gastric contents are refluxed into the esophagus and produce troublesome symptoms mainly heartburn and regurgitation. It may present with complications as well. Atypical presentation is also not very uncommon. Proper diagnosis and differentiation from other diseases can ensure appropriate treatment and thus better quality of life. Unlike many other diseases, diagnosis of GERD is relatively straight forward through symptomatology and a few investigations, even though few cases require special and technologically newer modalities of investigative tools for confirmation. Option for treatment are many and mostly medical; surgical and other methods are very rarely needed to pose better life. New molecules are recently being used with variable promising results and need exploration.J Shaheed Suhrawardy Med Coll, June 2016, Vol.8(1); 30-33

: The pandemic of coronavirus disease 2019 (COVID-19) has become a threat to human life and society. Scientists and clinicians are struggling with the intrusive SARS-CoV-2 virus to enhance their knowledge about its pathogenesis and find an effective medicine and vaccine to combat its complications. Till now, they have learned that this SARS-CoV-2 has not infected all people exposed to this virus, and also severe respiratory illnesses have not been observed in all infected patients. Patients over 65 or with underlying diseases are more vulnerable to develop severe disease. Based on this premise, a high challengeable question is why some people are more susceptible to this virus and others are not. The present study was aimed to reviewthe current information which explains the broad spectrum of COVID-19 presentation.Herewe discussed that how genetic background, immune system, underlying disease, smokingstatus as well as age, race, and gender affect COVID-19 susceptibility.

Thyroid disease often causes unspecific or mild symptoms, so laboratory tests are needed to confirm the functional diagnosis of the thyroid disorder. The laboratory tests which are important to establish the diagnosis of thyroid disorder include: total and free thyroidhormones, its related (thyroid) hormone binding proteins and auto antibodies. The thyroid hormone tests are mostly measured with competitive or sandwich immunoassays and each method can be interfered by several factors. Some drugs may increase or decrease thethyroid functional tests and several factors such as: underlying diseases, age, pregnancy, occurrence of heterophil antibody and auto antibodies may also interfere the thyroid tests results. The interpretation of an unusual combination from thyroid stimulating hormonesuch as free thyroxin and tri-iodothyronine results needs confirmation of underlying condition for establishing the right diagnosis. This review is aimed to evaluate several factors which may influence the thyroid tests and interpretation.

Few data are available in the literature regarding Pneumocystis jirovecii infection in children under 3 years old. This retrospective cohort study aimed to describe medically relevant information among them. All children under 3 years old treated in the same medical units from April 2014 to August 2020 and in whom a P. jirovecii evaluation was undertaken were enrolled in the study. A positive case was defined as a child presenting at least one positive PCR for P. jirovecii in a respiratory sample. Medically relevant information such as demographical characteristics, clinical presentation, microbiological co-infections, and treatments were collected. The objectives were to describe the characteristics of these children with P. jirovecii colonization/infection to determine the key underlying diseases and risk factors, and to identify viral respiratory pathogens associated. The PCR was positive for P. jirovecii in 32 children. Cardiopulmonary pathologies (21.9%) were the most common underlying disease in them, followed by severe combined immunodeficiency (SCID) (18.8%), hyaline membrane disease (15.6%), asthma (9.4%) and acute leukaemia (6.3%). All SCID children were diagnosed with pneumocystis pneumonia. Co-infection with Pj/Rhinovirus (34.4%) was not significant. Overall mortality was 18.8%. Paediatric pneumocystis is not restricted to patients with HIV or SCID and should be considered in pneumonia in children under 3 years old.

AbstractAlthough computer-aided diagnosis (CAD) is used to improve the quality of diagnosis in various medical fields such as mammography and colonography, it is not used in dermatology, where noninvasive screening tests are performed only with the naked eye, and avoidable inaccuracies may exist. This study shows that CAD may also be a viable option in dermatology by presenting a novel method to sequentially combine accurate segmentation and classification models. Given an image of the skin, we decompose the image to normalize and extract high-level features. Using a neural network-based segmentation model to create a segmented map of the image, we then cluster sections of abnormal skin and pass this information to a classification model. We classify each cluster into different common skin diseases using another neural network model. Our segmentation model achieves better performance compared to previous studies, and also achieves a near-perfect sensitivity score in unfavorable conditions. Our classification model is more accurate than a baseline model trained without segmentation, while also being able to classify multiple diseases within a single image. This improved performance may be sufficient to use CAD in the field of dermatology.

The implementation of nanomedicine not only provides enhanced drug solubility and reduced off-target adverse effects, but also offers novel theranostic approaches in clinical practice. The increasing number of studies on the application of nanomaterials in kidney therapies has provided hope in a more efficient strategy for the treatment of renal diseases. The combination of biotechnology, material science and nanotechnology has rapidly gained momentum in the realm of therapeutic medicine. The establishment of the bedrock of this emerging field has been initiated and an exponential progress is observed which might significantly improve the quality of human life. In this context, several approaches based on nanomaterials have been applied in the treatment and regeneration of renal tissue. The presented review article in detail describes novel strategies for renal failure treatment with the use of various nanomaterials (including carbon nanotubes, nanofibrous membranes), mesenchymal stem cells-derived nanovesicles, and nanomaterial-based adsorbents and membranes that are used in wearable blood purification systems and synthetic kidneys.

Pruritus is a relatively common symptom that anyone can experience at any point in their life and is more common in the elderly. Pruritus in elderly can be defined as chronic pruritus in a person over 65 years old. The pathophysiology of pruritus in elderly is still unclear, and the quality of life is reduced. Generally, itch can be clinically classified into six types: Itch caused by systemic diseases, itch caused by skin diseases, neuropathic pruritus, psychogenic pruritus, pruritus with multiple factors, and from unknown causes. Senile pruritus can be defined as a chronic pruritus of unknown origin in elderly people. Various neuronal mediators, signaling mechanisms at neuronal terminals, central and peripheral neurotransmission pathways, and neuronal sensitizations are included in the processes causing itch. A variety of therapies are used and several novel drugs are being developed to relieve itch, including systemic and topical treatments.

Microencapsulation is a well-known technology for the lipid delivery system. It prevents the oxidation of fatty acids and maintains the quality of lipid after extraction from oil seed and processing. In flaxseed oil, the amount of ω-3 and ω-6 polyunsaturated fatty acids are 39.90–60.42% and 12.25–17.44%, respectively. A comprehensive review article on the microencapsulation of flaxseed oil has not been published yet. Realizing the great advantages of flaxseed oil, information about different technologies related to the microencapsulation of flaxseed oil and their characteristics are discussed in a comprehensive way, in this review article. To prepare the microcapsule of flaxseed oil, an emulsion of oil-water is performed along with a wall material (matrix), followed by drying with a spray-dryer or freeze-dryer. Different matrices, such as plant and animal-based proteins, maltodextrin, gum Arabic, and modified starch are used for the encapsulation of flaxseed oil. In some cases, emulsifiers, such as Tween 80 and soya lecithin are used to prepare flaxseed oil microcapsules. Physico-chemical and bio-chemical characteristics of flaxseed oil microcapsules depend on process parameters, ratio of oil and matrix, and characteristics of the matrix. As an example, the size of the microcapsule, prepared with spray-drying and freeze-drying ranges between 10–400 and 20–5000 μm, respectively. It may be considered that the comprehensive information on the encapsulation of flaxseed oil will boost the development of functional foods and biopharmaceuticals.

Background:Dermatological manifestations are not rare in patients with rheumatic diseases (RD). Multidisciplinary management and direct interaction between these disciplines are essential. According to Dermatology-Rheumatology clinics, most diagnoses evaluated are systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA), with dermatitis being the most common manifestation. It is important to be aware that skin problems in RD patients are not always related to the underlying condition(1). Nowadays, there is significant evidence to support the manifold advantages of the joint dermatology-rheumatology clinics, including improved quality of care for patients and multidisciplinary training for new physicians(2). This ongoing trend is intended to highlight the important interaction between specialties that treat overlapping conditions, and it has been incorporated in academic health centers to give a comprehensive approach to patients.Objectives:Our purpose was to describe the collaboration between the Rheumatology and Dermatology services during the evaluation of RD patients.Methods:An observational, retrospective study was performed in the Rheumatology Service of the University Hospital “Dr. Jose Eleuterio Gonzalez” in Monterrey, Mexico, between March 2019 and February 2020. All the patients with a Rheumatology or Dermatology consultation requested were included (hospitalized and outpatients). Demographic (age, gender, baseline diagnosis), the reason for consultation, specialty requested, type of treatment, final diagnoses, and agreement in final diagnosis were registered. Results are shown in descriptive statistics.Results:One hundred and seventy-four patients were included, 142 (81.6%) patients from the outpatient clinic and 32 (18.4%) patients hospitalized. The mean age was 45.1 (SD±15.8) years, 135 (77.6%) were females, 54 (31%) patients were under initial diagnosis evaluation, 30 (17.2%) had RA, 25 (14.4%) patients had SLE, 15 (8.6%) patients had psoriatic arthritis, 12 (6.9%) patients had systemic sclerosis, 6 (3.4%) patients had dermatomyositis. The main reasons for consultation in hospitalized patients were acute lupus (15.6%), subacute lupus (12.5%), purpura (12.5%), cutaneous vasculitis (9.4%), urticarial dermatitis (9.4%), dermatomyositis (6.3%) and others (34.3%). The consultation requested was: 156 (89.7%) to Dermatology and 18 (10.3%) to Rheumatology. The type of treatment prescribed was topic/local in 37 (21.3%) patients, systemic in 25 (14.4%) and both in 92 (52.9%) patients. The final diagnoses were related to the underlying disease in 102 (77%) patients and unrelated in 40 (23%) patients. The agreement between initial clinical suspicion and final diagnoses reached 75.9% between Rheumatology and Dermatology services. Figure 1.Conclusion:The collaboration between Rheumatology and Dermatology services are very important. Most of the patients were under initial evaluation. All the rheumatologists and dermatologists should be aware of the interdependence from both specialties to give the best quality of care to the patients.References:[1]Samycia M, McCourt C, Shojania K, Au S.
