  • Episcleritis This is an inflammation of the episclera, a thin layer of connective tissue between the conjunctiva and sclera. Episcleritis resembles conjunctivitis but is a more localized process and discharge is absent. Most cases of episcleritis are idiopathic, but some occur in the setting of an autoimmune disease. Scleritis refers to a deeper, more severe inflammatory process, frequently associated with a connective tissue disease such as rheumatoid arthritis, lupus erythematosus, polyarteritis nodosa, Wegener's granulomatosis, or relapsing polychondritis.

However, the Institute of Medicine estimates that 50–70 million Americans suffer from a chronic disorder of sleep and wakefulness, which can lead to serious impairment of daytime functioning.

  • Harrison's Internal Medicine Chapter 51. Menstrual Disorders and Pelvic Pain Menstrual Disorders and Pelvic Pain: Introduction Menstrual dysfunction can signal an underlying abnormality that may have long-term health consequences. Although frequent or prolonged bleeding usually prompts a woman to seek medical attention, infrequent or absent bleeding may seem less troubling, and the patient may not bring it to the attention of the physician. Thus, a focused menstrual history is a critical part of every female patient encounter.

  • Pelger-Hüet anomaly. In this benign disorder, the majority of granulocytes are bilobed. The nucleus frequently has a spectacle-like, or "pince-nez," configuration. In severe acute bacterial infection, prominent neutrophil cytoplasmic granules, called toxic granulations, are occasionally seen. Toxic granulations are immature or abnormally staining azurophil granules. Cytoplasmic inclusions, also called Döhle bodies (Fig. 61-3), can be seen during infection and are fragments of ribosome-rich endoplasmic reticulum.

  • Evaluation of Insomnia Insomnia is the complaint of inadequate sleep; it can be classified according to the nature of sleep disruption and the duration of the complaint. Insomnia is subdivided into difficulty falling asleep (sleep onset insomnia), frequent or sustained awakenings (sleep maintenance insomnia), early morning awakenings (sleep offset insomnia), or persistent sleepiness/fatigue despite sleep of adequate duration (nonrestorative sleep). Similarly, the duration of the symptom influences diagnostic and therapeutic considerations.

  • Restless Legs Syndrome (RLS) Patients with this sensory-motor disorder report an irresistible urge to move the legs, or sometimes the upper extremities, that is often associated with a creepycrawling or aching dysesthesias deep within the affected limbs. For most patients with RLS, the dysesthesias and restlessness are much worse in the evening or night compared to the daytime and frequently interfere with the ability to fall asleep. The symptoms appear with inactivity and are temporarily relieved by movement.

  • Shift-Work Disorder: Treatment Caffeine is frequently used to promote wakefulness. However, it cannot forestall sleep indefinitely, and it does not shield users from sleep-related performance lapses. Postural changes, exercise, and strategic placement of nap opportunities can sometimes temporarily reduce the risk of fatigue-related performance lapses. Properly timed exposure to bright light can facilitate rapid adaptation to night-shift work. While many techniques (e.g.

  • Behavioral Correlates of Sleep States and Stages Polysomnographic staging of sleep correlates with behavioral changes during specific states and stages. During the transitional state between wakefulness and sleep (stage 1 sleep), subjects may respond to faint auditory or visual signals without "awakening." Memory incorporation is inhibited at the onset of NREM stage 1 sleep, which may explain why individuals aroused from that transitional sleep stage frequently deny having been asleep.

  • Hemolytic Uremic Syndrome HUS is a syndrome characterized by acute renal failure, microangiopathic hemolytic anemia, and thrombocytopenia. It is seen predominantly in children and in most cases is preceded by an episode of diarrhea, often hemorrhagic in nature. Escherichia coli O157:H7 is the most frequent, although not only, etiologic serotype. HUS not associated with diarrhea (termed DHUS) is more heterogeneous in presentation and course.

  • More recent studies using molecular methods and a retrievable enamel chip model have revealed a new line-up of initial colonizers though the early dental plaque microflora varies at subject-specific basis (Diaz et al., 2006; Kolenbrander et al., 2005). In initial plaque on the chip at four to eight hours, Streptococcus spp. was dominant while Veillonella, Gemella, Prevotella, Niesseria, Actinomyces and Rothia were also frequently found. Among streptococci, S. oralis, S. mitis, S. infantis, S. sanguinis, S. parasanguinis, S. gordonii, S. cristatus and S.

  • Harrison's Internal Medicine Chapter 111. Venous Thrombosis Venous Thrombosis: Introduction Venous thrombosis is the result of occlusive clot formation in the veins. It occurs mainly in the deep veins of the leg (deep vein thrombosis, DVT), from which parts of the clot frequently embolize to the lungs (pulmonary embolism, PE). Fewer than 5% of all venous thromboses occur at other sites (see "Thrombosis at Rare Sites," and "Superficial Thrombophlebitis," below).

  • The relationship between household banking status and AFS use is complex. A non-trivial share of unbanked households (29.5 percent) do not use any of the AFS providers asked about in the survey, suggesting they rely primarily on cash. However, overall, unbanked households are more active AFS users than underbanked households. Unbanked households are more likely to use multiple products and to have used AFS, particularly transaction products, more recently and more frequently than under- banked households.

  • Oculomotor Nerve The third cranial nerve innervates the medial, inferior, and superior recti; inferior oblique; levator palpebrae superioris; and the iris sphincter. Total palsy of the oculomotor nerve causes ptosis, a dilated pupil, and leaves the eye "down and out" because of the unopposed action of the lateral rectus and superior oblique. This combination of findings is obvious. More challenging is the diagnosis of early or partial oculomotor nerve palsy.

  • Urinary incontinence was temporary, disappearing within 3 months. By the transurethral technique, continence can be reserved because the operator can easily detect the external sphincter, and supporting structures surrounding the prostate therefore allow the urethra to remain intact. The most excellent results of postoperative continence after radical prostatectomy are reported 93.0 % as to open prostatectomy (Walsh et al., 2000), 97.4 % as to laparoscopic surgery (Christopher et al., 2011) and 98.0 % as to robot-assisted surgery (Patel et al., 2005).
