Traumatic vasospastic disease in chain-saw operators. (1/2344)

Raynaud's phenomenon is commonly induced in chain-saw operators by vibration; the hand guiding the tool is the more severely affected. The condition tends to persist after use of the chain-saw is stopped but compensation is rarely sought. Among 17 cases of Raynaud's phenomenon in lumberjacks the condition was found to be related to use of the chain-saw in 14, 10 of whom had to give up their work in colder weather because the disease was so disabling. Two criteria essential to establish the condition as vibration-induced Raynaud's phenomenon are the presence of symptoms for at least 2 years and a history of at least 1 year's constant use of the chain-saw. Careful physical examination and simple tests of vascular function will provide objective evidence of permanent damage by which the patients may be classified and compensated.  (+info)

Mechanical stimulation of starfish sperm flagella. (2/2344)

1. The responses of starfish sperm flagella to mechanical stimulation with a microneedle were analysed. Flagellar movement was recorded by high-speed microcinematography and by stroboscopic observation. 2. The amplitude of the bending wave of a flagellum was restricted over its entire length when the microneedle was brought near to the flagellum at its proximal region. Beyond the restricted part, the amplitude of the wave, and the bend angle, became smaller than those of a normally beating flagellum, while the curvature was practically unchanged. 3. When the tip of the microneedle was in contact with the flagellum, propagation of the bending wave beyond the microneedle was inhibited. The part of the flagellum between the base and the microneedle continued beating in some cases and stopped beating in other cases. The flagellum beyond the arrested part stopped beating and remained straight. When the microneedle was removed, the bending wave which existed in the part of the flagellum proximal to the microneedle, or the wave which was passively formed de novo at the time of the removal of the microneedle, propagated over the arrested part towards the tip. 4. A flagellum amputated by a microneedle in a medium containing ATP continued beating with a small amplitude, small curvature, small bend angle and low frequency. When the amputated flagellum was passively bent by a microneedle at the region near the point of amputation, this bend propagated towards the tip with a constant bend angle. 5. The beating frequency of the flagellum could be modulated by the application of a rhythmic external force generated by vibrating a microneedle near the flagellum. The beating was completely synchronized with vibration of the microneedle in the frequency range from 23 Hz to 43 Hz.  (+info)

The two-dimensional IR nonlinear spectroscopy of a cyclic penta-peptide in relation to its three-dimensional structure. (3/2344)

A form of two-dimensional (2D) vibrational spectroscopy, which uses two ultrafast IR laser pulses, is used to examine the structure of a cyclic penta-peptide in solution. Spectrally resolved cross peaks occur in the off-diagonal region of the 2D IR spectrum of the amide I region, analogous to those in 2D NMR spectroscopy. These cross peaks measure the coupling between the different amide groups in the structure. Their intensities and polarizations relate directly to the three-dimensional structure of the peptide. With the help of a model coupling Hamiltonian, supplemented by density functional calculations, the spectra of this penta-peptide can be regenerated from the known solution phase structure. This 2D-IR measurement, with an intrinsic time resolution of less than 1 ps, could be used in all time regimes of interest in biology.  (+info)

A pilot study on the human body vibration induced by low frequency noise. (4/2344)

To understand the basic characteristics of the human body vibration induced by low frequency noise and to use it to evaluate the effects on health, we designed a measuring method with a miniature accelerometer and carried out preliminary measurements. Vibration was measured on the chest and abdomen of 6 male subjects who were exposed to pure tones in the frequency range of 20 to 50 Hz, where the method we designed was proved to be sensitive enough to detect vibration on the body surface. The level and rate of increase with frequency of the vibration turned out to be higher on the chest than on the abdomen. This difference was considered to be due to the mechanical structure of the human body. It also turned out that the measured noise-induced vibration negatively correlated with the subject's BMI (Body Mass Index), which suggested that the health effects of low frequency noise depended not only on the mechanical structure but also on the physical constitution of the human body.  (+info)

Brief vibrotactile stimulation does not increase cortical oxygen consumption when measured by single inhalation of positron emitting oxygen. (5/2344)

Vibrotactile stimulation of the hand elicits no increase in oxygen consumption commensurate with the increase in blood flow measured in human sensory cortex. To test the hypothesis that previous failures to detect a proportionate increase in oxygen consumption could be an artefact of the sequential bolus, or three-step, method used to measure this parameter in the human brain in vivo, the authors compared the measurements with the results of a novel single bolus, or one-step, method of measuring oxygen consumption. The time of completion of the three-step method was 40 to 50 minutes, whereas the one-step method lasted only 3 minutes. The baseline whole-brain oxygen consumption averaged 185 +/- 32 micromol hg(-1) min(-1) by the three-step method and 153 +/- 15 micromol hg(-1) min(-1) by the one-step method. Vibrotactile stimulation did not elicit a significant increase in oxygen consumption measured by either method. This finding rejects the hypothesis that failure to detect an increase of oxygen consumption could be an artefact caused by limitations of the method used previously. Conversely, it also rejects the hypothesis that observations of an increase of oxygen consumption by the new method are artefacts caused by limitations of the one-step method.  (+info)

Oxygen consumption of cerebral cortex fails to increase during continued vibrotactile stimulation. (6/2344)

The coupling of oxidative metabolism to the blood flow of the sensory motor hand area is uncertain. The authors tested the hypothesis that continued vibrotactile stimulation ultimately must lead to increased oxygen consumption consumption. Twenty-two healthy right-handed young volunteers underwent positron emission tomography (PET) with the [(15)O]water bolus injection method to measure water clearance (K1H2O an index of blood flow (CBF), and with the [(15)O]oxygen bolus inhalation method to measure CMR(O2). The CMR(O2) was measured 30 seconds and 20 minutes after onset of intermittent (1 second on, 1 second off) vibrotactile stimulation (110 Hz) and compared with baseline measurements without stimulation. The K1H2O and CMR(O2) changes (delta K1H2O and delta CMR(O2)) were determined using intersubject averaging, together with magnetic resonance imaging based stereotaxic registration technique. The K1H2O increase was 21 +/- 4% and 12 +/- 4% at 30 seconds and 20 minutes after onset of stimulation, respectively. No significant increase of CMR(O2) was found until 30 minutes after the onset of stimulation. The authors conclude that blood flow and oxidative metabolism undergo uncoupling during sustained phasic stimulation of the sensory hand area. Therefore, neuronal activity stimulated in this manner does not rely on significantly increased oxidative phosphorylation.  (+info)

Possible sources of discrepancies in the use of the Semmes-Weinstein monofilament. Impact on prevalence of insensate foot and workload requirements. (8/2344)

OBJECTIVE: The purpose of this study was to evaluate the effects of different testing sites and buckling strengths on the sensitivity and specificity of using the Semmes-Weinstein monofilament to detect patients with insensate foot. The impact on workload required to educate and follow up these high-risk individuals was estimated by modeling in our patient population with a documented status of neuropathy. RESEARCH DESIGN AND METHODS: Using the 5.07/10-g monofilament, one observer tested 132 randomly selected subjects with diabetes at five sites on the right foot. The sensitivity and specificity of each site and combinations of sites in detecting vibration perception threshold > 40 was calculated. In addition, two monofilaments, one with a buckling force of 5 g and the other with a force of 15 g, were compared by testing 200 randomly selected patients. An estimate of the prevalence of insensate foot and workload was made by modeling the findings to the 5,270 patients with neuropathy status registered on our computerized database. RESULTS: Specificity of the 5.07/10-g monofilament to detect insensate foot at each of the five sites is high, at approximately 90%, but there is considerably more variation and lower sensitivity, ranging from 44-71%. Data derived from the use of different combinations of sites showed that more stringent criteria are associated with lower sensitivity but higher specificity. If the foot is considered insensate when either of sites 3 and 4 (plantar aspect of the first and fifth metatarsal heads, respectively) cannot feel the monofilament, there is reasonable sensitivity and specificity (80-86%, respectively). By modeling on our diabetes center population, it can be demonstrated that the choice of different methodologies leads to different conclusions about the prevalence of severe neuropathy, ranging from 3.4 to 29.3%. CONCLUSIONS: Using a combination of sites 3 and 4 for monofilament testing gives a reasonable compromise for time, sensitivity, and specificity. Minor changes in sensitivity and specificity can lead to major changes in the prevalence of neuropathy, with implications for workload.  (+info)

HAVS is typically caused by prolonged exposure to vibrations from hand-held power tools, such as jackhammers, drills, and sanders. The vibrations can cause damage to the blood vessels, nerves, and joints in the hands, leading to the development of HAVS.

There are several risk factors for developing HAVS, including:

1. Prolonged exposure to hand-transmitted vibrations
2. Use of high-vibration tools and equipment
3. Poor tool maintenance and repair
4. Inadequate training on the safe use of tools and equipment
5. Smoking and other cardiovascular risk factors

The symptoms of HAVS can vary in severity and may include:

1. Numbness, tingling, or pain in the hands and fingers
2. Reduced dexterity and grip strength
3. Fatigue and weakness in the hands and arms
4. Tremors or spasms in the hands and fingers
5. Pale or discolored skin on the fingers and hands
6. Decreased sensation in the fingertips
7. Swelling, redness, or warmth in the hands and fingers

If left untreated, HAVS can lead to more severe symptoms, including:

1. Permanent nerve damage
2. Loss of dexterity and grip strength
3. Decreased sensation in the fingertips
4. Finger ulcers and amputations
5. Carpal tunnel syndrome
6. Other neurological disorders

There is no cure for HAVS, but it can be managed with a combination of medical treatment and lifestyle changes. Treatment options may include:

1. Medications to relieve symptoms such as pain and inflammation
2. Physical therapy to improve dexterity and grip strength
3. Lifestyle modifications such as avoiding cold temperatures and taking regular breaks to warm up hands
4. Assistive devices such as gloves, splints, or hand braces
5. Surgery in severe cases to relieve compression on nerves or repair damaged tissue.

Prevention is the best course of action for HAVS, and it involves taking steps to reduce exposure to cold temperatures and other risk factors. Some ways to prevent HAVS include:

1. Using proper protective gear such as gloves, hats, and scarves in cold environments
2. Avoiding prolonged exposure to cold temperatures
3. Taking regular breaks to warm up hands and fingers
4. Exercising regularly to improve circulation and reduce risk factors such as smoking and obesity
5. Maintaining a healthy diet and getting enough sleep.

The exact cause of Raynaud disease is not fully understood, but it is believed to be related to an autoimmune disorder, in which the body's immune system mistakenly attacks healthy tissue. The condition can occur on its own or as a secondary symptom of another underlying medical condition such as scleroderma or rheumatoid arthritis.

Symptoms of Raynaud Disease:

1) Discoloration: Raynaud disease causes the affected areas to turn white or blue in response to cold temperatures or stress.

2) Pain: The constriction of blood vessels can cause pain in the affected areas.

3) Numbness or tingling: The lack of blood flow can cause numbness or tingling sensations in the fingers and toes.

4) Swelling: In severe cases, swelling may occur in the affected areas.

5) Burning sensation: Some people with Raynaud disease may experience a burning sensation in their hands and feet.

Diagnosis of Raynaud Disease:

1) Medical history: A doctor will ask about symptoms, medical history, and any triggers that may cause the condition.

2) Physical examination: The doctor will perform a physical examination to look for signs of discoloration or swelling in the affected areas.

3) Tests: Additional tests such as nailfold capillary microscopy, pulse volume recording and thermography may be ordered to confirm the diagnosis.

Treatment options for Raynaud Disease:

1) Medications: Drugs such as calcium channel blockers, alpha-blockers, and anticoagulants can help to relax blood vessels and improve blood flow.

2) Lifestyle changes: Avoiding triggers such as cold temperatures and taking steps to keep hands and feet warm can help manage the condition.

3) Alternative therapies: Some people with Raynaud disease may find relief with alternative therapies such as acupuncture or biofeedback.

It is important to note that in some cases, Raynaud disease can be a symptom of an underlying autoimmune disorder, such as lupus or scleroderma. If you suspect you have Raynaud disease, it is essential to seek medical attention to rule out any other conditions.

Occupational diseases can be difficult to diagnose and treat, as they often develop gradually over time and may not be immediately attributed to the work environment. In some cases, these diseases may not appear until years after exposure has ended. It is important for workers to be aware of the potential health risks associated with their job and take steps to protect themselves, such as wearing protective gear, following safety protocols, and seeking regular medical check-ups. Employers also have a responsibility to provide a safe work environment and follow strict regulations to prevent the spread of occupational diseases.

Treatment: Treatment for arm injuries can range from conservative methods such as rest, ice, compression, and elevation (RICE) to surgical interventions. The goal of treatment is to relieve pain, promote healing, and restore function to the affected arm.

Peripheral Nervous System Diseases can result from a variety of causes, including:

1. Trauma or injury
2. Infections such as Lyme disease or HIV
3. Autoimmune disorders such as Guillain-Barré syndrome
4. Genetic mutations
5. Tumors or cysts
6. Toxins or poisoning
7. Vitamin deficiencies
8. Chronic diseases such as diabetes or alcoholism

Some common Peripheral Nervous System Diseases include:

1. Neuropathy - damage to the nerves that can cause pain, numbness, and weakness in the affected areas.
2. Multiple Sclerosis (MS) - an autoimmune disease that affects the CNS and PNS, causing a range of symptoms including numbness, weakness, and vision problems.
3. Peripheral Neuropathy - damage to the nerves that can cause pain, numbness, and weakness in the affected areas.
4. Guillain-Barré syndrome - an autoimmune disorder that causes muscle weakness and paralysis.
5. Charcot-Marie-Tooth disease - a group of inherited disorders that affect the nerves in the feet and legs, leading to muscle weakness and wasting.
6. Friedreich's ataxia - an inherited disorder that affects the nerves in the spine and limbs, leading to coordination problems and muscle weakness.
7. Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) - an autoimmune disorder that causes inflammation of the nerves, leading to pain, numbness, and weakness in the affected areas.
8. Amyotrophic Lateral Sclerosis (ALS) - a progressive neurological disease that affects the nerve cells responsible for controlling voluntary muscle movement, leading to muscle weakness, atrophy, and paralysis.
9. Spinal Muscular Atrophy - an inherited disorder that affects the nerve cells responsible for controlling voluntary muscle movement, leading to muscle weakness and wasting.
10. Muscular Dystrophy - a group of inherited disorders that affect the nerve cells responsible for controlling voluntary muscle movement, leading to muscle weakness and wasting.

It's important to note that this is not an exhaustive list and there may be other causes of muscle weakness. If you are experiencing persistent or severe muscle weakness, it is important to see a healthcare professional for proper evaluation and diagnosis.

Transmissibility is the ratio of output to input. It is defined as the ratio of the force transmitted to the force applied. Transmitted force implies the one which is being transmitted to the foundation or to the body of a particular system. Applied force is the external agent that cause the force to be generated in the first place and be transmitted. Transmissibility: T = output input {\displaystyle T={\frac {\text{output}}{\text{input}}}} T > 1 {\displaystyle T>1} means amplification and maximum amplification occurs when forcing frequency ( f f {\displaystyle f_{f}} ) and natural frequency ( f n {\displaystyle f_{n}} ) of the system coincide. There is no unit designation for transmissibility, although it may sometimes be referred to as the Q factor. The transmissibility is used in calculation of passive hon efficiency. The lesser the transmissibility the better is the damping or the isolation system. T < 1 {\displaystyle ...
