Symptoms usually begin with a partial involvement of the nail will eventually extend to involve the matrix (nail root). The possible absence of pain and slow the progression of the condition are precisely the main reasons why consulting a doctor when the disease is already well advanced.
The most common signs of onychomycosis affecting the shape and appearance of the nail, and they are: Read the rest of this entry »
Risk Factors of Onychomycosis
What are the risk factors?
A number of environmental conditions, personal and social character that could cause an increased risk of fungal infection of nails. Onychomycosis is a genetic alteration but a number of conditions that predispose to it, such as vascular diseases affecting the immune system (body’s defense system). All are diseases that cause poor oxygenation of the nails or decrease the body’s defenses and, therefore, increase the likelihood of infection.
These diseases can name the following:
- Diabetes
- Neurological diseases
- Arterial Disease
- Blood Diseases
- Diseases affecting the immune system Read the rest of this entry »
Onychomycosis
What are they and what causes them?
Onychomycosis is defined as any infection of the fingernails or toenails caused by different types of fungi. The infection can come from within one or another fungal infection in other locations.
Although infection caused by each type of fungus receives a specific name, it is true that all are grouped under the generic name of onychomycosis. Infections can be produced by four different types of fungi:
- Dermatophytes (ringworm of the nail)
- Candida yeast (candida nail)
- Filamentous fungi
Diagnosis of Heel Spur
How does the doctor diagnose?
The heel spurs are diagnosed by symptoms and signs present during the examination of the patient.
To confirm the diagnosis and rule out other pathologies responsible for heel pain such as arthritis, your doctor may order other examinations such as X-rays (X rays).
Once developed a heel spur can be a picture difficult to treat. However, in many cases there has been only a minor injury to ligaments can heal within several weeks or months.
Preventing, avoiding or correcting predisposing factors early in the picture may improve the prognosis and the long-term. Read the rest of this entry »
Symptoms and Risk Groups of Heel Spur
What are the symptoms of a heel spur?
- Severe pain, like pins on the inside of the heel.
- The pain typically disappears at rest, but worse when standing.
- In general, pain is more intense in the morning.
- The pain worsens when walking on a hard surface, or carry something heavy, like a suitcase.
- The pain can be so severe as to prevent normal daily activities.

Most people who are overweight and suffer from middle age. This is because the fat pad under the heel, in charge of absorbing shock, atrophies with age and lose their effectiveness. Read the rest of this entry »
Heel Pain and Heel Spurs
What is heel spur?
A heel spur is a small bone formation that forms on the calcaneus (heel bone). Appears to be under the sole to weigh heavily for an extended period of time.
What is the cause of heel pain and heel spurs?
At every step, one of his two heels has to support the weight of the body. By the way, the load on the heel is 20 times the body weight. This burden is mitigated by a fat pad (fat) under the heel and a fascia (fibrous sheath that protects the tendons and muscles) under the sole. Read the rest of this entry »
Diagnosis of Herniated Disk
How does the doctor diagnose?
Diagnosis is made by performing an adequate medical history (patient interview) and a physical examination can often determine what the affected disk.
Subsequently, the diagnosis is confirmed by additional examinations: an MRI (Magnetic Resonance Imaging), CT (Computed Tomography) or a myelogram (injection of radiopaque contrast into the intervertebral disc).
Your doctor will decide what type of exploration should be performed. It is important to diagnose properly because there are several conditions that share the same symptoms. Read the rest of this entry »
Symptoms of Herniated Disk
What are the symptoms of a herniated disk?
A hernia can be asymptomatic or may cause pain as a result of the compression exerted on the nerve roots, spinal cord or cauda equina.
Symptoms of nerve root compression
Pain, tingling and loss of strength in certain areas and muscle groups in the upper limb (arm) or lower limb (leg), depending on the affected root. In the lower limb syndrome causes sciatica or sciatic nerve.
Symptoms due to compression of the spinal cord
- Muscle spasm or paralysis, tingling and numbness in the part of the body located below the level of compression. For example, a compression on the spinal cord in the thoracic region cause impairment in the legs but no arms. Read the rest of this entry »
Disk Herniation
What is the spinal disc?
The spine consists of vertebrae and between each of them has a cartilage disc. This disc consists of a circular connective tissue (annulus) with a gelatinous core (nucleus pulposus). This allows the column to be flexible and also can act as a protective structure.
In the center of this column of vertebrae and discs is the spinal canal, inside of which is the spinal cord, which extends from the brainstem to the 1st or 2nd lumbar vertebra. From there it continues as a bundle or bundle of nerve fibers (called the cauda equina), which extends to the sacrum, which is a continuation of the spine. Each intervertebral space nerve root leaves the spinal cord that connects to other parts of the body.
The vertebral column (spine) is divided into three parts: cervical spine (neck), thoracic spine and lumbar spine. At the height of the thoracic spine vertebrae articulate with the ribs. Read the rest of this entry »
Refractive Surgery Techniques
Requirements to operate
Basically, the criteria for selecting a patient for refractive surgery are two:
- Aged over 18 years, considering the growth process finished eye at that age.
- The visual defect must be stable, ie should not have varied more than one diopter in the year prior to the intervention.
Refractive surgery techniques
The choice of surgical treatment is important to note that one should not generalize and that the way forward will depend on multiple factors, not just scientists or doctors, but also on the characteristics, requirements and expectations of each patient. Read the rest of this entry »
