Deep vein thrombosis (DVT) is defined as the formation of a blood clot (thrombus) in a deep vein, most commonly in the legs, but it can also occur in the arms, mesenteric, and cerebral veins. This condition is part of the broader category of venous thromboembolism (VTE) disorders, which are significant causes of morbidity and mortality, particularly due to the risk of pulmonary embolism (PE) if the clot dislodges and travels to the lungs. DVT is often associated with various risk factors, including hematologic malignancies, immunologic disorders, and the presence of genetic predispositions or thrombotic drugs that stimulate coagulation processes.…

Restless legs syndrome (RLS) is a common neurological sensory-motor disorder characterized by an uncontrollable urge to move the legs, often accompanied by uncomfortable sensations such as burning, tingling, or aching, particularly during periods of rest or inactivity and worsening in the evening or at night. These sensations are typically relieved by movement, leading to motor restlessness and sleep disturbances, including difficulties in sleep onset and maintenance, and excessive daytime sleepiness. RLS can be idiopathic or secondary to conditions such as iron deficiency, pregnancy, chronic renal failure, and peripheral neuropathies, with a significant genetic component suggested by familial aggregation and autosomal-dominant…
Anemia is a condition characterized by a reduction in the mass of red blood cells or the amount of hemoglobin, leading to decreased oxygen delivery to organs. The World Health Organization (WHO) defines anemia as hemoglobin (Hb) levels below 12.0 g/dL in women and below 13.0 g/dL in men. This definition, however, can vary based on factors such as age, sex, ethnicity, and physiological status. In older adults, anemia is often defined by similar Hb thresholds, but the condition is more prevalent and can be associated with various underlying causes, including nutritional deficiencies, chronic diseases, and unexplained factors. Anemia in…
Palpitations are commonly defined as an unpleasant awareness of the heartbeat, often described by patients as sensations of fluttering, pounding, racing, or irregular beating in the chest. These sensations can vary in duration, from brief moments to several minutes, and may be perceived as either rapid or forceful heartbeats. While palpitations are frequently benign and related to non-cardiac causes such as anxiety or stress, they can also be indicative of underlying cardiac arrhythmias or other serious conditions. The pathophysiology of palpitations involves complex neural pathways that are not yet fully understood, and they can be triggered by a variety of…
High cholesterol, also known as hypercholesterolemia, is a condition characterized by elevated levels of cholesterol in the blood. Cholesterol is a waxy, fat-like substance essential for building cell membranes, producing certain hormones, and aiding in fat digestion. However, excessive cholesterol can increase the risk of heart disease. Familial hypercholesterolemia (FH) is a specific type of high cholesterol that is inherited and marked by elevated low-density lipoprotein cholesterol (LDL-C), significantly raising the risk of premature atherosclerotic cardiovascular disease. Acquired hypercholesterolemia, on the other hand, is often linked to high-fat diets, particularly those rich in saturated fats, and a sedentary lifestyle, contributing…
Low blood pressure, or hypotension, is a condition characterized by blood pressure readings that are lower than the normal accepted standards. Historically, the definition of normal blood pressure has evolved, particularly with advancements in measurement techniques such as the mercurial sphygmomanometer and the auscultatory method. Traditional formulas, like 100 plus the age in years for systolic pressure, have been abandoned due to their inaccuracy in defining normal ranges. In elderly populations, low blood pressure is often associated with increased mortality and can be influenced by factors such as cardiovascular disease and frailty. For instance, systolic pressure below 122 mmHg and…
Angina, derived from the Latin verb “angere” meaning to strangle, is a clinical manifestation of ischemic heart disease (IHD) characterized by chest discomfort due to inadequate blood flow to the heart muscle. This condition, often precipitated by physical exertion or emotional stress, is typically relieved by rest or nitroglycerin. Angina can present as substernal chest pain, pressure, or discomfort, and may also radiate to the arms, jaw, or upper back, signaling that the heart is not receiving sufficient oxygen. There are various forms of angina, including stable angina, which is predictable and occurs with exertion, and unstable angina, which is…
Gout is a form of arthritis characterized by the deposition of monosodium urate crystals in joints and other tissues, leading to acute and chronic inflammatory responses. It is primarily caused by hyperuricemia, a condition where there is an elevated level of uric acid in the blood, which can result from genetic factors, dietary habits, and inefficient renal urate excretion. The disease manifests in four phases: asymptomatic hyperuricemia, acute gouty arthritis, intercritical gout, and chronic tophaceous gout. Gout typically presents as sudden, severe episodes of pain, tenderness, redness, warmth, and swelling in the affected joints, most commonly the big toe. The…
Foot pain is a multifaceted issue that can significantly impact an individual’s quality of life, particularly in older adults. It is often defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, aligning with the broader definition of pain by the International Association for the Study of Pain. Foot pain can be categorized based on its location, such as anterior, intermediate, or posterior foot pain, with specific conditions like Haglund disease causing posterior heel pain due to deformities in the calcaneus. The prevalence of foot pain is notable, affecting approximately one-quarter of the population at…
Repetitive strain injury (RSI) is a term used to describe a group of musculoskeletal disorders that affect muscles, tendons, nerves, and blood vessels, primarily due to repetitive and forceful motions, awkward postures, and other ergonomic hazards often encountered in occupational settings. These injuries can manifest in various forms, including carpal tunnel syndrome, cubital tunnel syndrome, lateral epicondylitis, and tendonitis of the wrist or hand. RSI is also known by other terms such as cumulative trauma disorders (CTD) in North America and occupational cervicobrachial disorders (OCD) in Japan and Scandinavia. The condition is not age-specific and can affect individuals who are…
Rheumatism, often used interchangeably with rheumatoid arthritis (RA), refers to a group of chronic inflammatory conditions primarily affecting the joints. RA is characterized by persistent synovitis, systemic inflammation, and the presence of autoantibodies such as rheumatoid factor (RF) and anticitrullinated protein antibodies (ACPA). It manifests as symmetrical polyarthritis, typically involving the small joints of the hands, wrists, and feet, and can lead to significant joint damage and disability if left untreated. The term “rheumatoid” was historically introduced to describe an inflammatory joint condition distinct from rheumatic fever, emphasizing its unique pathology. Modern definitions of RA also recognize its systemic nature,…
Arthritis is a term that encompasses a variety of joint disorders characterized by inflammation, pain, stiffness, and swelling in the joints. It is not a single disease but rather a group of over 100 rheumatic conditions that can affect the joints, surrounding tissues, and other connective tissues. The forms of arthritis range from osteoarthritis, which is related to the wear and tear of cartilage, to rheumatoid arthritis (RA), an autoimmune disease that causes chronic inflammation in the synovial joints and can lead to significant joint damage and disability if not adequately managed. Rheumatoid arthritis is particularly notable for its systemic…
Shin splints, also known as medial tibial stress syndrome (MTSS), is a term broadly used to describe pain along the tibia bone, typically brought on by exercise or athletic activity. This condition is characterized by pain and discomfort in the lower leg, often resulting from repetitive stress or overuse, which leads to inflammation of the periosteum (the lining of the bone) and the surrounding tissues. The pain associated with shin splints can be generalized across the lower two-thirds of the tibia and is often exacerbated by activities such as running or jumping. It is important to note that shin splints…
Osteoporosis is a skeletal disorder characterized by decreased bone mass and deterioration of bone microarchitecture, leading to increased bone fragility and a higher risk of fractures. It is commonly classified into two primary forms: postmenopausal osteoporosis (Type I) and age-related osteoporosis (Type II), with secondary causes including conditions such as hypercortisolism, hyperthyroidism, and immobilization. The disease is often asymptomatic until a fracture occurs, typically presenting as acute back pain from vertebral compression fractures or groin pain from hip fractures. The World Health Organization defines osteoporosis based on bone mineral density (BMD) measurements, with a BMD 2.5 standard deviations below the…
Neck and shoulder pain are prevalent musculoskeletal complaints that can arise from a variety of conditions and share overlapping symptoms, making differentiation challenging. Neck pain is often localized to the cervical region, while shoulder pain is typically associated with the shoulder joint and surrounding structures. However, both types of pain can be interconnected and may result from similar anatomicophysiological mechanisms, such as cervical disc disease, which can manifest as either neck or shoulder pain. Epidemiological research highlights the importance of distinguishing between localized neck or shoulder pain (LNSP) and more generalized pain involving these regions (GPNS), as they differ in…
A trapped nerve, also known as nerve entrapment, occurs when a nerve is compressed or constricted by surrounding tissues, such as muscles, tendons, or bones, leading to pain, paresthesias, and potential sensory and motor deficits. This condition is more prevalent in the upper extremities, including the cervical, thoracic, shoulder, elbow, and wrist areas, and can result from various etiologies such as anatomical abnormalities, ganglion cysts, muscle hypertrophy, trauma, or systemic conditions like diabetes mellitus and hypothyroidism. For instance, diabetic peripheral neuropathy can exacerbate nerve entrapment due to increased permeability of endoneurial capillaries, leading to the accumulation of plasma proteins on…
Sciatica is commonly defined as pain that radiates along the path of the sciatic nerve, which extends from the lower back through the hips and buttocks and down each leg, typically affecting only one side of the body. It is often described as radicular leg pain, sometimes accompanied by sensory, motor, or reflex deficits, and is usually caused by nerve root irritation due to intervertebral disc herniation. Historically, sciatica was thought to be caused by inflammation of the sciatic nerve or its roots, but more recent understanding attributes it primarily to conditions such as prolapsed intervertebral discs exerting pressure on…
Back pain is a multifaceted condition with various definitions depending on the context and specific type of pain being discussed. Low back pain (LBP) is often defined as pain localized in the lower back, lasting for more than 24 hours, and separated by at least one month without pain. Chronic back pain, on the other hand, is typically described as pain persisting for more than 7-12 weeks or beyond the expected period of healing, and it may not always have a clear pathological cause. Recurrent low back pain is characterized by multiple episodes of pain, with the frequency of these…
Varicose veins are abnormally twisted, lengthened, or dilated superficial veins, primarily found in the lower extremities, resulting from inefficient or defective valves within the veins. These veins are characterized by their tortuous and widened appearance, often leading to venous hypertension due to blood reflux. The condition is more prevalent in women and can be influenced by factors such as pregnancy, prolonged standing, obesity, and family history. While varicose veins are generally not life-threatening, they can cause significant discomfort, including aching legs, swelling, and itching, and may lead to more severe complications if left untreated. The World Health Organization defines varicose…
Bad breath, also known as halitosis, is a condition characterized by an unpleasant odor emanating from the oral cavity. It is a common issue that affects millions of people and can lead to social embarrassment and psychological distress. The primary cause of bad breath is often related to oral factors, such as poor oral hygiene, which leads to the release of sulfur compounds by bacteria in the mouth. However, it can also be associated with systemic conditions, including gastrointestinal and liver diseases, although these account for a smaller percentage of cases. The Talmud even considers bad breath a significant medical…
Dry mouth, also known as xerostomia, is a condition characterized by a noticeable reduction or absence of saliva in the mouth, leading to a persistently dry feeling. It is often a symptom of underlying issues rather than a disease itself, and can be caused by a variety of factors including prescription medications, medical treatments, and autoimmune diseases. Xerostomia can significantly impact an individual’s quality of life, affecting dietary habits, nutritional status, speech, taste, and increasing susceptibility to dental caries. It is particularly prevalent among older adults due to their higher usage of medications and susceptibility to diseases that affect salivary…
Toothache, commonly referred to as dental pain, is a multifaceted condition characterized by pain in or around the teeth and jaws. It is primarily caused by dental issues such as tooth decay, gum disease, tooth injury, or an exposed tooth root. The pain can range from mild discomfort to severe, excruciating pain and may sometimes be a result of referred pain from other conditions like cardiac issues, sinusitis, or neuralgias. Toothache is often associated with inflammation and can present with symptoms such as sensitivity, gum bleeding, and cavities. It is crucial to accurately diagnose the underlying cause of toothache to…
Gum problems, often referred to as periodontal diseases, encompass a range of conditions that affect the supporting tissues of the teeth. The term “gum” is commonly used to describe the fibrous tissue covered by mucous membrane that covers the alveolar process of the jaws and surrounds the necks of the teeth, while “gingiva” specifically refers to the portion of the gum that surrounds the teeth above the alveolar process. Periodontitis, a severe form of gum disease, is a bacterial infection that damages the structures supporting the teeth, potentially leading to tooth loss if untreated. The primary cause of gum problems…
Mouth ulcers, also known as aphthous ulcers, are painful open sores or lesions that form inside the mouth, either singly or in clusters. They are extremely common, affecting as many as one in five people, and tend to be more prevalent in women and individuals under the age of 40. These ulcers are characterized by a break in the mucosal surface of the oral cavity, often presenting as small, white sores with a red border. The majority of mouth ulcers are minor aphthous ulcers, which are self-limiting and typically heal within one week to ten days without scarring. However, mouth…
Conjunctivitis, commonly known as “pink eye,” is defined as an inflammation of the conjunctiva, the membrane that lines the inside of the eyelids and covers the white part of the eye. This condition can be caused by various factors, including bacterial, viral, and allergic agents, as well as other noninfectious causes. Infectious conjunctivitis typically results from the exogenous inoculation of pathogens, leading to a local inflammatory response. The condition can present in acute, hyperacute, or chronic forms, with symptoms such as redness, itching, discharge, and eyelid swelling. While most cases are self-limited, appropriate diagnosis and treatment are essential, especially in…
A stye, medically known as a hordeolum, is a common infection of the eyelid that typically develops rapidly over a few days. Styes can affect one or both eyes and may occur simultaneously on the same eyelid. There are two types of styes: external styes, which are more common, and internal styes, which are less frequent. External styes are characterized by acute suppurative inflammation of the lash follicle and associated glands of Zeis or Moll, often linked to habitual eye rubbing or chronic blepharitis. Internal styes, on the other hand, involve inflammation of the meibomian glands located within the eyelid.…
Eye irritation is a multifaceted condition characterized by symptoms such as dryness, itching, and pain, often reported in environments like offices, particularly among individuals engaged in visually demanding tasks. It can result from various factors, including the destabilization of the precorneal tear film (PTF), which leads to hyperosmolarity and inflammatory reactions. Inflammation plays a significant role, as it can cause structural and functional changes in the tear-secreting glands, contributing to the irritation. Sensory irritation, a prevalent symptom in “sick” buildings, involves both subjective sensations and objective changes like redness and edema, and is influenced by factors such as air quality…
Head lice, scientifically known as Pediculus humanus capitis, are small, wingless insects that infest the human scalp, particularly among school-aged children, though adults can also be affected. These parasites attach their eggs, or nits, to hair shafts close to the scalp, where they hatch in about 7-10 days. The mature lice, roughly the size of a sesame seed, feed on the host’s blood every few hours, which can cause itching and discomfort, although many cases are asymptomatic. Head lice are most commonly found behind the ears and at the back of the neck, and they remain close to the scalp…
Foot odor, also known as bromodosis, is a common and often embarrassing condition primarily caused by the metabolic activities of bacteria present on our skin. The primary cause behind the unpleasant smell is isovaleric acid, which is produced when Staphylococcus epidermidis, a normal resident of the skin’s microbial flora, degrades leucine present in sweat. Other bacteria such as Bacillus subtilis, Bacillus cereus, and Proteus mirabilis have also been implicated in the production of foot odor. The plantar surface of the foot, which harbors a higher concentration of Staphylococcus spp., is particularly prone to producing odorous volatiles like isovaleric acid. Additionally,…
Calluses are defined as areas of thickened skin that develop in response to chronic friction, pressure, or irritation. They serve as a protective mechanism, forming a barrier to prevent further damage to the underlying tissues. In plants, calluses refer to masses of unorganized tissues that arise from injury, consisting of undifferentiated cells that can vary in consistency from soft to hard. These plant calluses can be induced and cultured under specific conditions, leading to the development of differentiated plantlets. In humans, calluses are often seen as occupational stigmata, such as those found on the hands of professional milkers due to…
