Rhabdomyosarcoma is a soft tissue pediatric sarcoma composed of cells which show morphological, immunohistochemical and ultrastructural evidence of skeletal muscle differentiation. To date four major subtypes have been recognized: embryonal, alveolar, spindle cell/sclerosing and pleomorphic. All these subtypes are defined, at least in part, by the presence of rhabdomyoblasts, i.e. cells with variable shape, densely eosinophilic cytoplasm with occasional cytoplasmic cross-striations and eccentric round nuclei. It must be remembered, however, that several benign and malignant pediatric tumours other than rhabdomyosarcoma may exhibit rhabdomyoblaststic and skeletal muscle differentiation. This review focuses on the most common malignant pediatric neoplasm that may exhibit rhabdomyoblastic differentiation, with an emphasis on the most important clinicopathological and differential diagnostic considerations.

Increased exposure to electromagnetic fields such as radio frequencies used by Wifi technology raise questions and concerns about their impact on health. For answer these questions, several scientific studies have carried out followed by results publication in prestigious scientific revues. Literature conducted on the effects of non-ionizing radiation and Wifi waves is vast and sometimes controversial. Epidemiological studies and the results of in vitro and in vivo experimental studies have showed the biological effects of electromagnetic field in different frequencies range. These effects caused disorders at the molecular and behavioral level. However, these studies were insufficient to confirm the directly related effects to the cause. Therefore, further research must be done to raise the controversy about the safety of wireless waves.

What is called “idiopathic biliary duct system dilatation” or better to name it “un-explained biliary dilatation” is mostly following surgical procedures related to upper gastrointestinal and hepato-bilio-pancreatic systems. Having such situation, adaptive physiology of the biliary duct system has to be considered and rational has to be explained. The vast multimodal progress in techniques of investigations that has been applied on studying the hepato-bilio-pancreatic system has been utilized to clear the clinical ambiguity of biliary duct system dilatation for no logic reason but missing the correlation between both fields; the technical and the clinical ones. This clinical review is trying to fill this gap and introduce a comprehensive discussion of the subject. Mechanical, biochemical and immune causes constitute a wide diversity of etiology related to biliary system dilatation that in some situations is really difficult to verify clinically. On the least, even we could not verify the etiology we need to identify that reaching a closed road is different than postulating suspicions that never exist. This review is a trial collecting all subject-related data that might be related to etiology mechanisms and utilize to find a correlation rationale. At some point verification of such correlation is really a far target that might be even impossible clinically with availing technical tools and hope in the future could be achieved.

A thorough knowledge of the stationary characteristics of the nuclei of atoms, their stimulation wavelengths, how they react to outside factors, and how they disintegrate is the aim of nuclear structural science. Although achieving these objectives within just one structure is difficult and prevents the existence of a nuclear "standard model," it is evident that radioactive Density Functional Theory (DFT) offers perhaps the broadest variety of applications to date. We attempt to place DFT in a larger perspective in this study by making frequent allusions to electrical DFT. We also provide a brief overview of the numerous uses and an explanation of the connections between beginning techniques and Useful Field Concepts (EFTs) in particular. The article tries to promote collaborations with different scientific fields while being published from a subjective and perhaps biased point of view.

Age related macular degeneration is a severe disease of mainly elderly people and leads to central vision loss because of the degeneration of the retinal pigment epithelium [1]. Genetic and environmental factors are responsible for the accumulation of extracellular material and deposit formation near the retinal pigment epithelial (RPE) layer, which leads to loss of photoreceptors and induction of chronic inflammation. The deposits are composed of lipids and proteins including many complement proteins, indicating the involvement of the complement system in the degenerative process and chronic inflammation [2]. So far there is no treatment for the dry form of AMD, except nutritional supplementation with antioxidants and vitamins [3]. Combined with a prolonged lifetime expectation in developed countries, AMD is developing to a social and economic burden. Therefore, there is an urgent need for a treatment of AMD that can delay disease manifestation and progression for several years. 

Bone choristoma within a dermolipoma is a rare epibulbar tumor with a low prevalence. It is a benign tumor that does not usually cause discomfort or functional problems to patients who suffer from it. Its treatment is surgical and with an aesthetic purpose.We report the case of a 17-year-old patient with a bone choristoma, a tooth, within a dermolipoma.Epibulbar bone choristoma is a rare benign tumor that causes little discomfort to patients who suffer from it and is asymptomatic in most cases. Computed tomography (CT) is essential in its diagnosis and its treatment is surgical, but always due to aesthetic reasons.

Background: Although illegal, Ghana has a long history of cannabis use. With changing perceptions, advocacy for legalization has increased globally. This study exams pharmacological evidence on the prospects and challenges of decriminalization and /or legalization of cannabis in Ghana. Results: Cannabis and cannabinoids are a “pharmacological enigma” with unique ability to activate at least 3 of the 4 drug receptor super families. This include; inotropic Transient Receptor Potential Vanilloid 1 (TRPV1), metabotropic Cannabinoid Receptors (CB) and nuclear Peroxisome Proliferator Activator Receptors (PPAR). Cannabinoid receptors also dimerize with other receptors creating distinctly new signaling pathways. Cannabis and cannabinoids show good anti- nociceptive, anti-inflammatory, immunosuppressant anti-emetogenic activity and variable anticonvulsant activity. It can play important role in palliative care, some rare intractable epilepsy, multiple sclerosis, cachexia and Opioid Use Disorder. Cannabis precipitates psychosis in individuals with underlying genetic susceptibility. Chronic cannabis use alter the neurobiology of adolescent brain, predisposing them to amotivational syndrome characterized by depersonalization and inhibited motivation for goal directed behavior. Cannabis is also a “gateway drug”; ushering users to “harder” substances of abuse and reinstating extinguished drug seeking behaviours. The recent tramadol abuse in Ghana may have been precipitated by previous and concurrent cannabis use. Furthermore, Ghana’s cannabis may have a higher propensity to induce detrimental effects because of preferential accumulation the psychotropic delta-9-Tetrathydrocannabinol as a result of the high tropical temperature and humidity. Conclusion: There is not sufficient pharmacological evidence supporting criminalization of medical cannabis in Ghana. However, the same evidence does not support legalization of recreational cannabis.

Introduction: Intense Pulsed Light (IPL) is the therapeutic tool implemented in the treatment of dry eye, characterized by the emission of waves of 500-1200nm in the region of the upper and lower eyelids. Dry eye is a recurring complaint in ophthalmology offices and has an impact on the patient’s quality of life. It results from dysfunction of the meibomian glands, duct obstruction, and quantitative and qualitative changes in glandular secretion. It is manifested by dryness and irritation, foreign body sensation, burning, tearing, and eye fatigue. The available treatments are short term palliative with unsatisfactory results.

Introduction: Acute tubulointerstitial nephritis (ATIN) is an acute kidney injury (AKI) resulting from damage to the tubulointerstitial tissue due to infection, trauma, or use of medication. It is clinically non-specific. Case: A teenager with multiple trauma, hospitalised after lowering of level of conscience, and convulsion fits. While in the emergency ward, he received: midazolam, fentanyl and phenytoin. The cranial and abdominal CT scans were normal. He was stable with no signs of shock, trauma or infection; he developed oliguria and serum creatinine (Scr) 1.7mg/dL), 12 hours after the admission. After 36 hours, Scr levels were at 3.4mg/dL and urea at 55mg/dL. He had AKI according to pRIFLE (66.2% reduction in clearance). After other causes of AKI had been ruled out, the possibility of ATIN was raised; the phenytoin was suspended and pulse therapy, with methylprednisolone, was promptly initiated. After the first pulse, there was already a decline in the creatinine and urea readings; 48 hours later: Scr at 2.2mg/dL and urea at 86mg/dL. Thirty days after being discharged from hospital, the patient was in good health and had full restoration of kidney function. Discussion: The singularity of this report relies on the rarity of ATIN secondary to the use of phenytoin and also in the importance of recognizing this aetiology as being one of the origins of AKI. Conclusion: Early diagnosis allows the reversal of AKI through suppression of treatment with phenytoin and introduction of corticosteroid therapy, when necessary.

Introduction: Pneumothorax is a life-threatening condition that requires prompt recognition and therapy to prevent deterioration. Radiologist workload often precludes rapid assessment of the usual diagnostic modality, the chest radiograph, particularly after hours. The aim was to develop a deep learning model using a segmentation-based Deep Convolutional Neural Network (DCNN) to detect pneumothorax on chest radiographs to provide rapid and accurate pneumothorax diagnosis.Methods: This is a retrospective study of spontaneous pneumothorax at a single center, containing 130 positive and 70 negative radiographs. Subsequent manual contour mapping was performed to draw a mask of the pneumothorax. These image pairs were used to train a DCNN model (a modified AlexNet) after pretraining on the ImageNet dataset.Results: The DCNN achieved an accuracy of 0.83, with sensitivity of 98.1%, and specificity of 68.5%.Conclusion: This segmentation-based DCNN accuracy is comparable to previous categorization-based CDNN models, despite using a smaller sample size for training, while including the benefits of visual representation for clinician feedback. Segmentation-based DCNNs show promise in the development of accurate and clinically useful models for medical imaging.
