DIABETIC NEUROPATHIES. Diabetic neuropathies are a family of nerve disorders caused by diabetes. WHAT CAUSES DIABETIC NEUROPATHY. Nerve damage is likely due to a combination of factors. 1.METABOLIC FACTORS. : hyperglycemia, long duration of diabetes, abnormal blood fat levels and low levels of insulin. 2.NEUROVASCULAR FACTORS : Neurovascular factors leading to damage of blood vessels that carry oxygen and nutrients to nerves. 3.AUTOIMMUNE FACTORS : Causes inflammation of nerves. 4.MECHANICAL FACTORS : Injury to nerves as in carpel tunnel syndrome. 5.INHERITED TRAITS : That increase susceptibility to nerve disease. 6.LIFESTYLE FACTORS : Smoking, alcohol. SYMPTOMS. Symptoms depends on the type of neuropathy and which nerves are affected.Symptoms involve sensory,motor and autonomic nervous system. 1.Tingling, numbness or pain in the toes,feet,legs,hands,arms and fingers. 2.Wasting of muscles of hand or feet. 3.Indigestion, nausea, vomiting, diarrhea,c constipation. 4. Dizziness or fainting due to a drop in blood pressure after standing or sitting up. 5.Problems with urination. 6.Erectile dysfunction. 7.Weakness. TYPES OF NEUROPATHY. Diabetic neuropathy can be classified as 1.Peripheral neuropathy. 2.Autonomic neuropathy. 3.Proximal neuropathy. 4.Focal neuropathy. PERIPHERAL NEUROPATHY. Peripheral neuropathy,also called distal symmetric neuropathy or sensorimotor neuropathy ,is nerve damage in arms and legs.Symptoms are *Numbness or insensitivity to pain or temperature. *A tingling,burning or prickling sensation. *Sharp pains or cramps. *Extreme Sensitivity to touch. *Loss of balance and coordination. Peripheral neuropathy also causes muscle weakness and loss of refle guyxes.Blisters and sites may appear on the numb areas of the foot because pressure or injury goes unnoticed.I f an infection occurs and is not treated promptly,the infection may spread to the bone and the foot may need amputation.Many amputations can be prevented if minor problems are treated in time. AUTONOMIC NEUROPATHY. Autonomic neuropathy affects the nerves that control the heart,blood pressure and blood glucose levels.Autonomic neuropathy also affects internal organs causing problems with digestion,respiration. urination,sexual response and vision. 1.HYPOGLYCEMIA UNAWARENESS. Normally,symptoms such as shakiness,sweating and palpitations occurs when the blood glucose levels drop below <<70 mg/dl.In people with autonomic neuropathy,symptoms may not occur making hypoglycemia to be recognized. 2.HEART & BLOOD VESSELS. Damage to the nerves in the cardiovascular system interferes with the body's ability to adjust blood pressure and heart rate. Due to this,blood pressuremay drop sharply after standing or sitting,causing a person to feel light headed or faint. Damage to nerves that control heart rate makes the heart rate to stay high , instead of rising and falling in response to normal body functions and physical activity. 3.DIGESTIVE SYSTEM. Nerve damage to the digestive system most commonly causes constipation. Damage can also cause the stomach to empty slowly,a condition called GASTROPARESIS. Gastroparesis can lead to persistent nausea and vomiting,bloating and loss of appetite. Gastroparesis also makes blood glucose levels to fluctuate widely ,due to abnormal food digestion. Nerve damage to the OESOPHAGUS MAKES SWALLOWING DIFFICULT. Nerve damage to bowels can cause constipation alternating with uncontrolled diarrhea, 3.URINARY TRACT & SEX ORGANS. Autonomic neuropathy often affects the organs that control urination and sexual functions. Nerve damage can prevent the bladder from emptying completely , allowing the bacteria to grow in bladder and kidneys causing urinary tract infections. When the nerves of the bladder are damaged,urinary incontinence may result because a person may not be able to sense when the bladder is full or control the muscles that release urine. Autonomic neuropathy also leads to decreased sexual response in men and women. A man may have erectile dysfunction or may reach sexual climax without ejaculating normally. A woman may have difficulty in arousal,lubrication or orgasm. 5.SWEAT GLANDS. Nerve damage may cause improper working of sweat glands.It can also result in profuse sweating at night or while eating. 6.EYES. Due to autonomic neuropathy,pupils become less responsive to changes in light.A s a result,a person may not be able to see well when light is turned on In a dark room or have trouble driving at night. PROXIMAL NEUROPATHY. Proximal neuropathy//lumbosacral plexus neuropathy //femoral neuropathy //diabetic amyotrophy causes pain in the thighs,buttocks,hips or legs,usually on one side of the body. FOCAL NEUROPATHY. Focal neuropathy appears suddenly and affects specific nerves,most often in the head,torso or leg. Focal neuropathy is painful and unpredictable.and occurs most often in older adults with diabetes. However,it tends to improve itself over weeks or months and does not cause long term damage. Focal neuropathy can cause *Inability to focus the eye. *Diplopia. *Aching behind the eye. *Bell's palsy. *Severe pain in the lower back and pelvis. *Pain in the front of the thigh. *Pain in the chest and stomach. *Pain on the outside of the shin or inside of the foot. *Chest pain and abdominal pain is mistaken for heart attack or appendicitis. CAN DIABETIC NEUROPATHIES BE PREVENTED. THE BEST WAY TO PREVENT NEUROPATHY IS TO KEEP BLOOD GLUCOSE LEVELS AS CLOSE TO THE NORMAL RANGE AS POSSIBLE.MAINTAINING SAFE BLOOD GLUCOSE LEVELS PROTECTS NERVES THROUGH OUT THE BODY.

A known case of Pulmonary Koch's and Tuberculous liver abscess presented 2 and a half years back. Treated with resolution of liver abscess and continued ATT for 9 months - patient was lost to follow-up. Now the patient has presented with persistent tingling in both feet / soles and occasional tingling left palm since the time he was taking ATT that is for almost 2 years. No other symptoms. Chest and abdominal exam are normal. Reflexes normal. Peripheral sensations normal. Power normal in all 4 limbs. USG Abdomen does not show anything significant. MT negative. NCS is normal - report attached. Suggestions on diagnosis and management? EDIT: Patient has been put on various cominations of AEDs (Gabapantin, Pregabalin) and anti depressants (Duloxetin, amitriptyline, nortriptyline, venlafaxine) and Vit B12 at several centers with no relief. His current B12 level is 1187

45yrs diabetic male.. with this tropic ulcer since 1 yrs.. Treated by various doctors .. The ulcer area heals and recurs again at the same spot.. Too much keratinization seen surrounding it .. No sensation of pain felt.. Debridement and dressing done (with megaheal) by me along with antibiotics (augmentin).. Tough diabetes is controlled and brought below 180 post lunch.. No other comorbidities present.. Kindly guide me with the management and m also worrisome regarding it reoccurring... Thank you...
