Essays on Lesion

Post-stroke dysphagia, a potentially fatal complication, affects an estimated 23-50% of all stroke survivors. It is associated with a seven fold increase in the risk for aspiration pneumonia. Aspiration pneumonia increases the catabolic demands of the body and in the settings of impaired swallowing leads to a vicious cycle of malnutrition, dehydration, and further infections (Shaker & Geenen, 2011). Dysphagia affects a significant number of patients with hemispheric stroke which is the main subtype of ischemic stroke in the general population (Kumar et al., 2011). The functions of swallowing are subserved by a vast brain network. The inferior peri-rolandic sensorimotor ...

Literature Review:

Factors and predictors of persistent lesion (positive hr-HPV DNA test or abnormal cytology) after treatment of high grade cervical intraepithelial Neoplasia with large loop excision of transformation zone (LLETZ) {Author Name} {Institution Affiliation}

Introduction

The Human Papillomavirus (HPV) infection is the primary factor that increases the risk of the cervical cancer development and cervical intraepithelial neoplasia (CIN) in the uterine cervix (Soderlund-Strand et al., 2014). Approximately 150 diverse types of HPV have been discovered, and most of them are carcinogenic. Persistent infections of high-risk HPV must lead to the development of high-grade cervical intraepithelial neoplasia (CIN 2 and 3), and ...

The diagnostic reasoning for clinical diagnoses involves the collection of data and application of systematic approaches to formulating hypotheses and create lists of different diagnoses. However, sometimes the clinician can make errors that that have a direct impact on the way they handle a patient leading to incorrect diagnoses, treatments and overall management plan. Most medical errors are identified as systemic and are usually solved using various interventions as checklists. However, there are other errors that occur during diagnosis and treatment, and these are attributed to flawed diagnostic reasoning (Wellbery, 2011). Diagnostic reasoning errors are mostly caused by heuristics ...

Describe how a nerve impulse is transmitted from one neuron to the next

The transmission from one neuron to another is characterized by exchange of electric charge across the membrane of each neuron (Fields, 2014). An unstimulated neuron would be polarised (McCance 2014). In the polarized state, there is difference in the electric charge across the membrane. However, during exchange, a neuron is said to undergo polarization, wherein there is an excess of Na+ (sodium ions) outside and excess of K+ (potassium ions) on the outside (Fields, 2014). Nerve impulse is transmitted through the process of polarization, repolarization, and hyperpolarization (McCance 2014).

Compare the structure and functions of the CNS and PNS.

Introduction

Skin wounds are painful and cause irritation to their victims. They usually also present an avenue through which harmful microorganisms can gain access to the body and cause more damage. Therefore, they should be appropriately diagnosed and treated as soon as they occur. This paper will evaluate treatment and diagnosis of Herpes Zoster.

Properly Diagnosing Skin Wounds in Frail Elderly

Aging makes the thickness of the skin to reduce, and hence the skin becomes more susceptible to wounds (Burr, 2012). Proper diagnosis of wounds in old people is paramount since it dictates the efficiency with which the wounds would be treated. The skin should be assessed ...

Abstract

Paget's disease of the breast is an uncommon kind of cancer of the nipple–areola complex and that is time and again connected to a fundamental in situ or persistent carcinoma. We provide an overview and evaluate the key clinicopathological and healing aspects of mammary Paget's disease. Patients suffering from the Paget disease frequently present with a constant, eczematous skin complaint on the nipple and adjoining areolar skin. Paget's disease of the breast has been acknowledged as a separate clinical unit for over one hundred and twenty years. Since the situation in itself is repeatedly harmless and restricted to ...

Headache is a common complaint that afflicts most of the adult population at some point in their lives (Hainer & Matheson, 2013). Headaches are by and large a subjective phenomenon with few objectively measurable factors (McMurtray & Saito, 2014). Most headaches will be the benign, but a small percentage will indicate an underlying neurologic or systemic pathology (Hainer & Matheson, 2013). The purpose of this paper is to investigate the chief complaint, “I have headaches or a headache.” The paper will discuss the objective and subjective data that needs to be collected, headache triggers and drug treatments, and the health promotion strategies ...

International Air Law

Air transport is currently considered the fastest and safest means of transport globally, Passengers want to feel secure when flying from one place to another and expect the airline to be responsible in the event where they experience any form of injury while under the airline’s care. However, the application of treaties and agreements in determining the liability of airlines in instances of accidents has triggered debates as to what extent the airlines are liable for the damages experienced while the plaintiff is onboard. A particular question arises regarding the extent of injuries that an airline can be ...

Cardiovascular diseases are the illnesses of heart and blood vessels (arteries and veins) (World Health Organization). In fact, there are many different diseases of the cardiovascular system, but I would like to highlight the most common.

Arrhythmia

Arrhythmia is a condition in which the frequency, rhythm and sequence of heart contractions are violated. The symptoms occur because of various congenital anomalies, acquired diseases of the cardiovascular system, as well as under the influence of vegetative, hormonal or electrolyte disturbances and as a result of the adverse drug action. Violated heartbeat, weakness and fainting are frequent companions of arrhythmia. The diagnosis ...

Part A: Cranial Nerves:

There are 12 pairs of cranial nerves emerging from the brain’s underside passing via cranial openings leading to various parts of the head, neck and body trunk. These nerves are naming, and numbering of these nerves is based on their position i.e. from the anterior to the posterior of the brain. In this case, the olfactory nerve is CN1 while CN12 is the hypoglossal nerve (Wissmann, 2013). In this paper, only four of the twelve cranial nerves shall be discussed i.e. the Olfactory nerve (CN1), Oculomotor Nerve (CN-III) which are sensory nerves, and the Trigeminal Nerve (CN-V) and ...

Skin Biopsy

More often than not, a skin sample may appear to be abnormal with regards to the fact that the skin has changed color, shape, or appearance. The change in skin color, shape, or general appearance can be due to skin cancer, fungal infection, psoriasis or any other infection of the skin. To confirm the actual cause of such abnormality on the skin, dermatologists usually recommend a skin biopsy, which involves the removal of part of the skin for use in the histological examination or any other relevant tests. The word biopsy is derived from Greek words ‘bios’ meaning ‘life’ and ‘ ...
