Insulin Resistance
Insulin Resistance samer kareem 5,484 Views • 2 years ago

Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). The cells in your body need sugar for energy. However, sugar cannot go into most of your cells directly. After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream. Insulin then attaches to and signals cells to absorb sugar from the bloodstream. Insulin is often described as a “key,” which unlocks the cell to allow sugar to enter the cell and be used for energy.

Part 2: Translational Neuroscience of Excessive Daytime Sleepiness (EDS), Fatigue and Hype
Part 2: Translational Neuroscience of Excessive Daytime Sleepiness (EDS), Fatigue and Hype Mohammad Torabi Nami 8,902 Views • 2 years ago

Sleepiness, tiredness and fatigue are complaints which must be thoroughly analyzed to eliminate blur and ambiguity.
Physiological sleepiness (“sleep pressure”) increases while being awake and additionally underlies the circadian rhythm with a lower threshold to fall asleep during night time.
Excessive daytime sleepiness (EDS) is considered normal only after sleep deprivation. Clinically, EDS manifests by frequents daytime napping and/or reduced alertness with automatic behavior or - in its extreme form - in recurrent attacks of sudden, uncontrollable compulsion to sleep also in inappropriate situations (= “sleep attacks”).
EDS is “objectively” addressed by measuring the mean sleep latency to four to five nap opportunities throughout the day using the multiple sleep latency test (MSLT) or the maintenance of wakefulness test (MWT).
EDS denotes both, a ready entrance into sleep as well as difficulty in staying awake during daytime or accordingly in inappropriate situations. These two partially independent aspects of EDS are separately assessed by the “passive” MSLT and the “active” MWT respectively.
For that reason the MSLT and MWT only weakly correlate with each other when tested over a broad range of patients with EDS. It is important to keep in mind, that these tests are importantly influenced by a great variety of factors such as mood, anxiety, and motivation.
“Vigilance” comprises wakefulness, alertness and attention and therefore is more than just the reciprocal to sleepiness. Cognitive performance tasks such as Steer Clear Reaction Time Test (SCRTT) or driving simulators require the complete integrity of vigilance to achieve normal results. Hypersomnia is usually broadly defined as the combination of abnormally prolonged night-time sleep (regularly >10 h) with EDS during ≥1 months.
On the other hand, the term hypersomnia has also been used in a narrower scene for the isolated abnormality of a prolonged night-time sleep need (>10 h). “Tiredness”, also in colloquial language often used for sleepiness, in a broader sense also describes the feeling of lack of energy, motivation and initiative.

These patients seek rest rather than sleep. They often cannot fall asleep when given the opportunity in spite of feeling tired, and hence, in an MSLT, do not show an abnormally short sleep latency. Furthermore, tiredness (and fatigue) as opposed to sleepiness has a mental (“central”) and physiological (bodily or “peripheral”) component, which the patients can readily distinguish. Patients with insomnia, mild sleep apnea syndrome, or depression rather suffer from mental tiredness than sleepiness during the day.
The simple subjective self-assessment using the Epworth Sleepiness Scale (ESS) quite reliably differentiates between sleepiness and mental tiredness (without sleepiness), which makes it a widely used test. The term “fatigue” is also heterogeneously used.
In physiology the “fatigue” implied a “time on task performance decrement” to describe decreasing muscle force during a sustained physical effort. In clinical medicine one distinguishes physical (“peripheral”) from mental (“central”) fatigue and the term usually denotes a chronic and more abnormal situation than tiredness.
In a broad sense “fatigue” implies a deficiency in coping satisfactorily with mental and physical work load. The chronic fatigue syndrome entails both mental as well as a physical fatigue (so called “leaden paralysis” of limbs). Depressive states are often associated with insomnia and fatigue, but there are also cases with hypersomnia rather than insomnia ( non organic hypersomnia , “atypical depression” or “hypersomnolent depression”)
Sometimes these patients have a tendency to spend much of the day lying in the bed without actually sleeping (so called clinophilia). The basic and clinical aspects of fatigu

If you have gestational diabetes, your baby may be at increased risk of: Excessive birth weight. Extra glucose in your bloodstream crosses the placenta, which triggers your baby's pancreas to make extra insulin. This can cause your baby to grow too large (macrosomia).

Penile Fracture
Penile Fracture samer kareem 4,529 Views • 2 years ago

Traumatic penile injury can be due to multiple factors. Penile fracture, penile amputation, penetrating penile injuries, and penile soft tissue injuries are considered urologic emergencies and typically require surgical intervention. The goals of treatment for penile trauma are universal: preservation of penile length, erectile function, and maintenance of the ability to void while standing. Traumatic injury to the penis may concomitantly involve the urethra.[1, 2] Urethral injury and repair is beyond the scope of this article but details can be found in Urethral Trauma. Penile fracture Penile fracture is the traumatic rupture of the corpus cavernosum. Traumatic rupture of the penis is relatively uncommon and is considered a urologic emergency.[3] Sudden blunt trauma or abrupt lateral bending of the penis in an erect state can break the markedly thinned and stiff tunica albuginea, resulting in a fractured penis. One or both corpora may be involved, and concomitant injury to the penile urethra may occur. Urethral trauma is more common when both corpora cavernosa are injured.[4] Penile rupture can usually be diagnosed based solely on history and physical examination findings; however, in equivocal cases, diagnostic cavernosography or MRI should be performed. Concomitant urethral injury must be considered; therefore, preoperative retrograde urethrographic studies should generally be performed. See the images below.

Vascular Anastomosis
Vascular Anastomosis samer kareem 3,581 Views • 2 years ago

Although techniques of vascular anastomosis after trauma are numerous in type and form, most surgeons will default to the one associated with the greatest comfort and ease. This report offers a rapid and reliable repair using a conceptually and operationally simple technique. Its methodology is appropriate for all repairs, including cases mandating the insertion of vascular conduit. We have employed this technique for the past 15 years in nearly all patients with vascular injuries, regardless of the site and size of the vessel. This has included vessels of the neck, torso, upper and lower extremities. There have been no obvious complications associated with its use. Major advantages include: 1) the operating system is always oriented towards the surgeon, 2) the posterior row of sutures is placed as both ends are readily visualized, avoiding the need for potentially obscuring traction stitches, and 3) flushing is easily performed prior to completing the anterior suture row.

OverviewSymptomsTestingComplicationsTreatmentPreventionTakeawayRead This Next What is gonorrhea? Highlights Some people may never develop noticeable symptoms. Gonorrhea is usually treated with an antibiotic injection or oral antibiotics. You’re at a higher risk of contracting gonorrhea if you’ve had any other STDs. Gonorrhea is a sexually transmitted disease (STD). It’s caused by infection with the bacterium Neisseria gonorrhoeae. It tends to infect warm, moist areas of the body, including the: urethra (the tube that drains urine from the urinary bladder) eyes throat vagina anus female reproductive tract (the fallopian tubes, cervix, and uterus) Gonorrhea passes from person to person through unprotected oral, anal, or vaginal sex. People with numerous sexual partners or those who don’t use a condom are at greatest risk of infection. The best protections against infection are abstinence, monogamy (sex with only one partner), and proper condom usage. Behaviors that make a person more likely to engage in unprotected sex also increase the likelihood of infection. These behaviors include alcohol abuse and illegal drug abuse, particularly intravenous drug use. Advertisement Symptoms of gonorrhea Symptoms

Sex reassignment surgery for male-to-female involves reshaping the male genitals into a form with the appearance of, and, as far as possible, the function of female genitalia. Prior to any surgeries, patients usually undergo hormone replacement therapy (HRT), and, depending on the age at which HRT begins, facial hair removal. There are associated surgeries patients may elect to, including facial feminization surgery, breast augmentation, and various other procedures.

Dental implant surgery.
Dental implant surgery. samer kareem 2,800 Views • 2 years ago

Dental implant surgery is a procedure that replaces tooth roots with metal, screwlike posts and replaces damaged or missing teeth with artificial teeth that look and function much like real ones. Dental implant surgery can offer a welcome alternative to dentures or bridgework that doesn't fit well. How dental implant surgery is performed depends on the type of implant and the condition of your jawbone. Dental implant surgery may involve several procedures. The major benefit of implants is solid support for your new teeth — a process that requires the bone to heal tightly around the implant. Because this healing requires time, the process can take many months.

Are most spiders poisonous? The majority of the 3,000 spiders in the United States aren’t poisonous. Even if most spiders did bite, their fangs are too small or weak to puncture human skin. Their bites may leave itchy, red wounds that heal within a week or so. The spiders that do manage to bite through our skin and insert toxic venom can cause serious health complications. Read on to learn what spider bites look like, what spider varieties leave certain bites, and how to treat spider bites. What do spider bites look like? Identifying a spider bite is easier if you saw the spider that bit you, but it’s possible that you won’t notice the wound until hours later. Look for things like: swelling a red welt skin damage any troubling symptoms that accompany the bite Other possible symptoms that may accompany a spider bite include: itching or rash pain around the area of the bite muscle pain or cramping blister that’s red or purple in color sweating difficulty breathing headache nausea and vomiting fever chills anxiety or restlessness rashes swollen lymph glands high blood pressure Spider bites often take longer to heal than other insect bites, and they may affect skin tissues. It’s important to keep the bite clean to reduce the risk of infection. How to treat a spider bite at home In some cases, you can treat spider bites at home. For nonvenomous spider bites, follow these steps: Apply an ice pack on and off the bite for 10 minutes at a time. Elevate the area to reduce swelling. Take an antihistamine, such as diphenhydramine (Benadryl), to help with itching. Clean the area with soap and water to prevent infection. Apply antibiotic ointment to the area if blisters develop. Seek medical attention if you’re showing symptoms of a spider bite or if the symptoms don’t go away over time. Always seek medical attention if you suspect you’ve been bitten by one of the following species: brown recluse black widow hobo spider tarantula Brazilian wandering spider
