Simply the answer is NO. Radiation sickness is a condition that can occur when a person is exposed to high levels of ionizing radiation. It is damage to the body caused by exposure to a hefty radiation dose; generally, you don’t see it with diagnostic tests that use low energy. The absorbed dose is nothing but the amount of radiation absorbed by the body that determines how sick you’ll be.
The most common cause of radiation sickness is exposure to radioactive materials, which can also occur after radiation from X-rays, gamma rays, and other sources.
The initial symptoms of radiation sickness are usually nausea and vomiting. The time between exposure and onset of symptoms is a clue to how much radiation is absorbed. Symptoms of radiation sickness include fatigue, nausea, vomiting, diarrhea, loss of appetite, hair loss, skin irritation, and more. The severity of symptoms depends on the amount of radiation exposure and the person’s overall health.
Risk factors for radiation sickness include:
Working with radioactive materials.
Living in areas with high levels of background radiation.
Having specific medical procedures.
Diagnosis of radiation sickness is typically made by measuring the person’s exposure to radiation and considering their symptoms.
Radiation sickness treatment aims to prevent radioactive contamination, treat life-threatening injuries like burns and trauma, treat symptomatic treatment, and manage pain. Treatment of radiation sickness is typically supportive, such as providing fluids and rest. Treatment of bonemarrow suppression is with Filgastrim. End-of-life care for radiation sickness typically includes hospice care and support for the person’s symptoms.
When to see a doctor for radiation sickness depends on the person’s symptoms and exposure.
Complications of radiation sickness can include organ damage, cancer, and even death.
Prevention of radiation sickness includes avoiding exposure to high levels of ionizing radiation and using protective clothing and equipment when working with radioactive materials.
We do X-rays, CT scans and stereotactic radiosurgery but we rarely find the radiation sickness at Dr Raos Hospital.
Acute respiratory distress syndrome (ARDS) is a life-threatening lung condition when the lungs cannot provide adequate oxygen to the body. The cause of ARDS is typically a viral or bacterial infection, but it can also be caused by other conditions such as trauma, sepsis, or pneumonia.
ARDS can occur in people of any age but is most common in adults. Age and severity of the illness increase the death rate. Most of the people who develop ARDS don’t survive. Many who survive will have long-lasting symptoms. Are you looking for the best Acute respiratory distress syndrome care? Please visit Dr. Raos hospital Guntur for your well-being.
Symptoms
Symptoms of ARDS include shortness of breath, rapid breathing, low blood pressure, and chest pain. The symptoms and signs of ARDS can vary in intensity; depending on its severity and cause, the presence of lung or heart disease will increase the severity.
Causes
Damage to the alveolar membrane leads to ARDS
Sepsis. The most common cause
Inhalation of harmful substances – smoke, chemical fumes, aspirating vomit, or near-drowning episodes.
Severe pneumonia.
Head, chest, or another significant injury. Accidents to the lungs or to the brain that controls breathing
COVID-19
Pancreatitis
massive blood transfusions
burns.
Diagnosis
No specific test to diagnose
The physical exam is the most important
SPo2
Chest X-ray
Computerized tomography (CT)
Lab tests – CRP, check for signs of infection or anemia
Electrocardiogram.
Echocardiogram
Treatment
The first goal in treating ARDS is to improve oxygen levels in your blood. Without oxygen, your organs can’t function properly. Treatment of ARDS typically involves mechanical ventilation and supplemental oxygen.
Fluids – strict Input output measurement to prevent either pulmonary fluid overload or shock
Relieve pain and discomfort
Prevent and treat infections
Minimize gastric reflux
Prevent blood clots
Sedate
When should you see a doctor for your respiratory ARDS illness?
If you experience any of the symptoms of ARDS, you should see a doctor immediately. ARDS can lead to severe complications, such as organ failure, and can be fatal, including Blood clots in your legs and pulmonary embolism, Collapsed lung (pneumothorax), Infections, and Scarring (pulmonary fibrosis)
Do survivors will get rid of all the symptoms?
Survivors of ARDS will have Breathing problems, Depression, Problems with memory and thinking clearly, Tiredness, and muscle weakness.
What should you do following the ARDS recovery?
Lifestyle and home remedies
Quit smoking. If you smoke, seek help to quit, and avoid secondhand smoke whenever possible.
Get vaccinated. The yearly flu (influenza) shot and the pneumonia vaccine every five years can reduce your risk of lung infections.

Signs and Symptoms of Stroke
One of the most important things to know about stroke is how to identify it. The signs and symptoms of stroke can be divided into two categories: those that occur suddenly and those that develop gradually.
The sudden onset of symptoms is often the most obvious sign that someone is having a stroke. Some of the most common sudden onset symptoms include:
-Sudden weakness or numbness in the face, arm, or leg (usually on one side of the body)
-Sudden confusion or trouble speaking
-Sudden trouble seeing in one or both eyes
-Sudden trouble walking, dizziness, or loss of balance
-Sudden severe headache with no known cause
Gradual onset symptoms are not as immediately obvious, but they can still be indicative of a stroke. Some of the most common gradual onset symptoms include:
-Gradually worsening weakness or numbness in the face, arm, or leg (usually on one side of the body)
-Gradually worsening confusion or trouble speaking
-Gradually worsening trouble seeing in one or both eyes
-Gradually worsening trouble walking, dizziness, or loss of balance
-Gradually worsening headache
If you experience any of these symptoms, it is important to seek medical help immediately as time is of the essence when it comes to stroke treatment.
Treatment and Prevention
There are many things that can be done to treat and prevent stroke. Some of the key treatment measures include:
-Prompt medical attention: If you think someone is having a stroke, it is important to call 911 or get to a hospital as soon as possible. Time is of the essence when it comes to stroke treatment, and the sooner someone gets medical attention, the better their chances are of recovery.
-Medications: There are many different medications that can be used to treat stroke, including clot-busting drugs, blood thinners, and blood pressure medications.
There are also many things that can be done to prevent stroke. Some of the key prevention measures include:
-Maintaining a healthy lifestyle: Eating a healthy diet, exercising regularly, and maintaining a healthy weight can help reduce your risk of stroke.
-Controlling blood pressure: High blood pressure is a major risk factor for stroke, so it is important to keep it under control. This can be done through lifestyle changes and/or medication.
-Avoiding smoking: Smoking is a major risk factor for stroke, so quitting (or never starting) is one of the best things you can do to reduce your risk.
The best Awake neurosurgery hospital in Guntur, Dr. Raos
Dr. Raos hospital routinely uses local, regional and spinal anesthesia when performing most of the minimally invasive brain and spinal surgeries. There will be less post-operative pain and a shorter duration of surgery with the awake local and spinal anesthesia procedures compared to general anesthesia.
“This is a real swift in neurosurgery following awake surgeries,” says Dr. Rao, a renowned neurosurgeon from Guntur in India. “Our studies and experience show that spinal and regional anesthesia are safe and offer real patient benefits.”
Dr. Raos Hospital’s regional anesthesia and spinal anesthesia protocols are used for selected individuals undergoing minimally invasive spinal surgeries like laminectomy, discectomy, or transforaminal lumbar interbody fusion (MIS-TLIF). These procedures are completed within 2 to 3 hours, the typical duration of spinal anesthesia or regional anesthesia.
There have been many myths about awake surgery regarding pain and not being able to stay still for the whole time, but those are not true in selected patients.
General anesthesia has several disadvantages for individuals undergoing brain or spinal surgery, including nausea, vomiting, memory loss, and temporary impairment of motor and sensory functions. “General anesthesia might affect cognition in older individuals, which is one of the main concerns,” Dr. Rao says.
The specific advantages of regional or spinal anesthesia include the following:
· total operating room time will be decreased by 25%
· Lower overall and maximum pain in the first six hours after surgery
· Ambulation on an average 8 hours earlier than general anesthesia
· Shorter hospital stays of at least one day
Awake brain and spinal surgery is a multidisciplinary effort. “It requires mutual understanding of neurosurgeons and anesthesiologists who are experts in respective fields and should work together,” Dr. Rao says.
The minimally invasive spine surgeries are performed with patients in either a supine or prone position. Dr. Raos Hospital avoids spinal anesthesia for patients with a BMI over 35 or with obstructive sleep apnea due to carbon dioxide retention in the body.
Generally, we use awake brain surgery in tumor cases, DBS, and all kinds of minimally invasive brain surgeries on cooperative patients. The procedure we employ in the spine in almost all short, minimally invasive spine surgeries. We used motorized screws to enhance the speed of the procedure.
During all minimally invasive brain and spinal surgeries, patients wear listening devices like earphones and listen to their favorite music. “we are in constant communication with the patient, and we make sure that they are comfortable and doing well throughout the procedure,” Dr. Rao says.
“The dominance of general anesthesia is mostly due to a lack of exposure to regional scalp block and spinal anesthesia,” Dr. Rao says. “At Dr. Raos hospital, we are committed to innovating our approaches in ways that help patients; we always strive to get the best to our patients.”
If you are looking for awake neurosurgery with fewer disadvantages for your minimally invasive brain or spine surgery, please consult Dr Raos Hospital, the best neurosurgery hospital in India with the best minimally invasive keyhole neurosurgeon. Contact us @ 9010056444 or 9010057444
The best keyhole surgery for brain tumors is at Dr. Rao’s Hospital.
Dr. Rao’s hospital offers minimally invasive keyhole surgery using a tubular retractor system that substantially lowers the risk of damaging eloquent tissue while removing deep-seated lesions. The procedure provides an advantage for selected patients with high-grade subcortical gliomas, metastatic brain tumors, or vascular lesions.
Dr. Rao Says
“It is a precise approach. You go deep within the brain because of a minimal disturbance—it is like no one knew you were there,” says Dr. Mohana Rao Patibandla, a top neurosurgeon in India at Dr. Rao’s Hospital, Guntur, India. “Patients usually have less blood loss, less pain, less retraction injury, less hospital stay, and less time to go work than they do with open surgery.”
Advantage compared to the traditional approach
Typically, the approach to deep-seated lesions involves a large craniotomy, extensive retractor blade cortical and subcortical retraction, and dissection—all — which contribute to collateral damage morbidity. “Another advantage of keyhole surgery is that the incision can be 2 inches long, unlike 10 to 15 inches in the open surgeries,” Dr. Rao says. “The craniotomy bone opening is a little bit larger or equal to a rupee coin, and we work within a tube with a diameter a little bit smaller than a quarter rupee coin.”
Tubular retractors and white matter-sparing
The tubular retractor spreads out the brain’s white matter tracts, exposing the tumor and providing a small round channel for tumor dissection and removal. “Otherwise, bladed retractors stretch the brain white matter tracts and often cut them, but the tubular retractor pushes the tracts aside and dissipates, and the tracts go to the previous position once we remove the tube,” Dr. Rao says.
Exoscopes
Exoscopes will have good magnification and excellent visualization compared to microscopic technology, are highly useful in minimally invasive procedures, are more ergonomic, and allow us to get light down into areas we could not before,” Dr. Rao says.
The keyhole surgery takes about 3 hours, depending on the lesion’s location. Patients generally go home on the same or immediate next postoperative day. “Generally, patients who had open resection stay in the hospital for five or six days,” Dr. Rao notes.
Recent Research
Tubular retraction can be an effective tool for biopsying deep-seated lesions to guide chemo and radiotherapy when open surgical resection is inappropriate. According to new research, a tubular retractor with exoscopic optics can safely remove deep lesions to get enough tissue for histopathological diagnosis and molecular genetics evaluation.
The researchers also noted that tubular retraction provides more tissue than stereotactic biopsy. “You can see the tumor up close. You know exactly what tissue you are removing,” Dr. Rao says.
Advanced training
These MIS techniques require a highly technologically demanding surgeon’s high level of expertise. “This procedure is highly technique-using. Surgeons who do this must be skilled in MIS, endoscopic, and exoscopic procedures,” Dr. Rao says.
Are you looking for the best minimally invasive keyhole brain surgery using a brain tubular retractor, advanced technology like neuronavigation, neuromonitoring, SONOSTAR CUSA, an exoscope, a microscope, and an endoscope? Your choice is Dr. Raos Hospital, Guntur – the best neurosurgery hospital in India, and Dr. Rao is the best neurosurgeon in India, as per evidence. Please contact us at 9010056444 or 9010057444.

ADHD is diagnosed by psychiatrists, psychologists, or neuro doctors using criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM is a guidebook mental health professionals use to diagnose mental disorders. To be diagnosed with ADHD, a person must have symptoms that are present for at least six months and interfere with functioning in at least two areas of life, such as school, work, or relationships.
Treatment
There is no cure for ADHD, but there are effective treatments. The most common treatment is medication, which can help to control the symptoms of ADHD. Other treatments include behavioral therapy, which can help to teach skills such as time management and organization, and educational therapy, which can help to improve academic performance.
Associated Conditions
Several conditions are associated with ADHD, including learning disabilities, anxiety disorders, and depression. ADHD can also lead to problems in relationships, employment, and education.
Disabilities
ADHD can lead to several disabilities, including learning, memory, and executive functioning problems. Executive functioning includes skills such as planning, organization, and time management. ADHD can also lead to social skills, communication, and self-control problems.
