Nail clubbing - Wikipedi

Nail clubbing, also known as digital clubbing or clubbing, is a deformity of the finger or toe nails associated with a number of diseases, mostly of the heart and lungs. When it occurs together with joint effusions, joint pains, and abnormal skin and bone growth it is known as hypertrophic osteoarthropathy. Clubbing is associated with lung cancer, lung infections, interstitial lung disease, cystic fibrosis, or cardiovascular disease. Clubbing may also run in families, and occur unassociated wit One theory is that clubbing is a response to arterial hypoxaemia, in which release of an unknown humoral substance causes dilation of the vessels of the fingers and the toes. Another is that clubbing results from a neurovascular abnormality. In support of this is the fact that a vagal section may reverse clubbing The mechanism underlying clubbing is not definitively known. An increased flow of blood through the capillaries due to a neurocirculatory reflex could cause tissue hypertrophy and hyperplasia of.. Clubbing is a condition that affects the nails in certain people. Besides certain diseases being known to cause it, clubbing's mechanism is caused by a Mendelian dominant trait

What is clubbing?<br />In simple terms clubbing is the bulbous enlargement of the fingertips along with an increase in anteroposterior as well as lateral curvature of the nails<br />2<br /> 3. What is the definition of clubbing?<br />Clubbing is defined as the bulbous enlargement of the terminal phalanges due to proliferation of connective tissue between the fingernail and the bone.<br />3<br /> Clubbing is a medical condition first described by Hippocrates in which the fingers (and/or toes) have the appearance of upside-down spoons. It is caused by a build-up of tissue in the distant part of the fingers (terminal phalanges), that causes the end of the fingers to become enlarged and the nails to curve downward Unilateral Clubbing. Clubbing is generally bilateral, but in some conditions, it may occur unilaterally. Unilateral clubbing is usually associated with local vascular lesions of the arm, axilla, and thoracic outlet and with hemiplegia. Aneurysm of the subclavian artery is commonly reported in the literature to cause unilateral clubbing

theories about the mechanism of clubbing - General

What Causes Clubbing of the Fingers or Toes

  1. Digital clubbing is one of the oldest, yet poorly understood, signs in clinical medicine. Hypertrophic osteoarthropathy is a clinical.
  2. Clubbing refers to swelling in the tip of the digit that results in loss of the normal angle seen between the nail and the nail bed. The fingertips appear broader and rounder when clubbing is present. While the exact mechanism that leads to clubbing is poorly understood,.
  3. Lovibond's profile sign: Normally, there is a sharp angle between the nail bed and the cuticle.When you have clubbing, the natural angle is lost as the nail angles down instead of up. Distal/interphalangeal depth ratio: The phalanges of your finger are the sections between each bending joint.Your distal phalange, the one that includes your nail, is normally shorter depth-wise than the.
  4. Clubbing is an increase in the soft tissue under the proximal nail plate of the distal part of the fingers or toes. Its causes are varied, the mechanism unknown (1). Clubbing was first described by Hippocrates in 400 BC in an empyema patient (hence also known as hippocratic fingers) (2)
  5. al phalanx of a digit, with subsequent loss of the normal angle between the nail and nail bed. The first stage of clubbing is a periungual erythema and a softening of the nail bed; this is followed by an increase in the Lovibond's angle (the angle between the proximal nail fold and the nail plate)
  6. Lung cancer is the most common cause of clubbing. Clubbing often occurs in heart and lung diseases that reduce the amount of oxygen in the blood. These may include: Heart defects that are present at birth (congenital); Chronic lung infections that occur in people with bronchiectasis, cystic fibrosis, or lung abscess; Infection of the lining of the heart chambers and heart valves (infectious.
  7. Clubbing is enlargement of the tips of the fingers or toes and a change in the angle where the nails emerge.

Mechanism of clubbing? - Answer

Nail Clubbing - Overview. Nail clubbing is a change in the structure of fingernails or toenails in which the finger and nail take on the appearance of an upside-down spoon, and become red and sponge-like. Clubbing is a medical condition first described by Hippocrates in which the fingers (and/or toes) have the appearance of upside-down spoons Several different theories have been put forward to try and explain why clubbing occurs. Currently the most likely candidates are a circulating vasodilator, a neurocirculatory mechanism, hypoxia and platelet-activated growth factor released from unfragmented megakaryocytes , .These theories each has counterevidence which have prevented their widespread acceptance and left the underlying. The mechanism behind digital clubbing has yet to be fully elucidated, with hypotheses ranging from a circulating vasodilator, tissue hypoxia, a neurocirculatory reflex, and genetic factors. 1 Although hypoxemia is often cited as a cause of clubbing, it is often absent in the presence of clubbing and many patients with hypoxemia do not have clubbing

The mechanism underlying clubbed fingers is not definitively known. An increased flow of blood through the capillaries due to a neurocirculatory reflex could cause tissue hypertrophy and hyperplasia of the tissues. It is not clear whether the same mechanism contributes to inherit clubbing PathophisiologyPathophisiology The specific pathophysiologic mechanism ofThe specific pathophysiologic mechanism of digital clubbing remains unknown. Many theoriesdigital clubbing remains unknown. Many theories have been proposed, yet none have receivedhave been proposed, yet none have received widespread acceptance as a comprehensivewidespread. Most theories behind the mechanism of clubbing include an association with right to left circulatory shunting, possibly leading to increased vascular growth factors in systemic capillaries. For example, the most popular current theory is that megakaryocytes, normally filtered in the pulmonary capillaries form the venous circulation are released in the the arterial circulation due t Clubbing in liver disease is associated with multiple small pulmonary arteriovenous anastomoses which allow large particles through. Hypertrophic osteoarthropathy probably shares the same mechanism, and is mainly attributable to PDGF release; but there may also be altered platelet function and an additional growth factor derived from the lungs Both spoon nails and clubbing are such definite reaction patterns that there must be some common mechanism for each deformity. Structural rules that should apply to the nail have been used. It is easy to think of multiple internal disorders producing the same connective tissue changes that alter the angle of the nail matrix

Clubbing also occurs in some congenital heart disorders and liver disorders. In some cases, clubbing may be inherited and not indicate any disorder. Clubbing itself does not need treatment. Recognizing Finger Clubbing. Finger clubbing is characterized by enlarged fingertips and a loss of the normal angle at the nail bed The exact mechanism by which hypoxaemia results in clubbing is not fully understood, but is thought to involve growth factors in vascular endothelium and platelets (See this article to learn more about the mechanism). Hence as the lower limbs experience more hypoxaemia, they develop more clubbing and cyanosis This material is known to cause increased capillary permeability and connective tissue hypertrophy. It is suggested that this mechanism is the cause of clubbing of the fingers The exact pathophysiological mechanism for each cause of clubbing is unknown but an increase in vascular endothelial growth factor appears to be an important common pathway. Vascular endothelial growth factor causes vascular hyperplasia, edema, and fibroblast or osteoblast proliferation in the distal nails

Even though clubbing is a widely recognized symptom of many diseases the physiological mechanism that actually causes clubbing is not well understood. Current understanding is that these diseases..

Clubbing is a physical examination finding first described by Hippocrates in 400 bc. Clubbing can be primary (pachydermoperiostosis or hypertrophic osteoarthropathy) or secondary (pulmonary, cardiac, or GI disease or HIV). Diagnosis is clinical based on nail fold angles and phalangeal depth ratios

A new hypothesis on the mechanism of digital clubbing secondary to pulmonary pathologies.

The jury is out on the underlying cause or mechanism of clubbing. Theories vary widely, and although pathways differ, the end results are the same. Proposed mechanisms include circulating vasodilators, neural, genetic inheritance, hypoxia and platelet-derived growth factor. According to Schwartz, Hypertrophic osteoarthropathy as a syndrome.

A new hypothesis on the mechanism of digital clubbing secondary to pulmonary pathologies. Med Hypotheses. Due to this variability, there is a corresponding inconsistency in the presentation of clubbing. Although testing of this hypothesis would be difficult, there is evidence to support our theory; including a link to chronic diseases. common cardiopulmonary disorders, the mechanism of production of these sounds is inade-quately understood. The goal of this research was to gain insights into the mechanism of crackle generation by systematic examination of the relationship between inspiratory and expiratory crackle characteristics Clubbing of nail is a medical sign in which the finger or the toe appears as an upside down spoon. The exact mechanism of finger or nail clubbing is not known, but it is believed to be caused as a result of hypoxia (low oxygen saturation in blood). Long time hypoxia may result in compensatory dilatation of tiny blood vessels in the terminal. Our hypothesis concerns the chronic activation of macrophages, and the continual production of pro-fibrotic tissue repair factors, as a cause of digital clubbing in an array of pulmonary pathologies. The level of macrophage activation will differ between individuals, corresponding to the variable immune response to these pulmonary pathologies Summary. The examination of the pulmonary system is a fundamental part of the physical examination that consists of inspection, palpation, percussion, and auscultation (in that order). Recognition of surface landmarks and their relationship to underlying structures is essential

Periosteal proliferation of the tubular bones characterized by (i) painful symmetrical arthritis of the ankles, knees, wrists and elbows, and (ii) digital clubbing. Mechanism is due to secretion of various factors including VEGF, PDGF, and prostaglandin E2. Distant metastasis. Metastatic sites include brain, bone, liver and adrenal gland Tetralogy of Fallot results in low oxygenation of blood. This is due to a mixing of oxygenated and deoxygenated blood in the left ventricle via the ventricular septal defect (VSD) and preferential flow of the mixed blood from both ventricles through the aorta because of the obstruction to flow through the pulmonary valve. The latter is known as a right-to-left shunt Google allows users to search the Web for images, news, products, video, and other content The specific pathophysiologic mechanism of digital clubbing remains unknown. Many theories have been proposed, yet none have received widespread acceptance as a comprehensive explanation for the phenomenon of digital clubbing. As stated best by Samuel West in 1897, Clubbing is one of those phenomena with which we are all so familiar that we.

Hemoptysis is defined as the spitting of blood derived from the lungs or bronchial tubes as a result of pulmonary or bronchial hemorrhage.1 Hemoptysis is classified as nonmassive or massive based. The most complex path to toxicity involves more steps (Figure 3-1).First, the toxicant is delivered to its target or targets (step 1), interacting with endogenous target molecules (step 2a) or altering the environment (step 2b), triggering perturbations in cell function and/or structure (step 3), which initiate repair mechanisms at the molecular, cellular, and/or tissue levels (step 4)
