Her mother reports that the child has a healthy appetite erectile dysfunction doctors boise idaho discount extra super avana 260mg fast delivery, a varied diet erectile dysfunction prescription drugs discount extra super avana 260 mg with amex, and no history of abnormal stooling. She is concerned, though, that her daughter has been getting progressively paler since her last clinic visit with another provider 6 months ago. Physical examination reveals an overall healthy-appearing toddler with normal vital signs. She has pallorous skin and conjunctivae and a well-healed abdominal surgical scar. You order a complete blood count and a reticulocyte count and find that the hemoglobin is 7 g/dL, the mean corpuscular volume is 110 fL, and the reticulocyte count is 2%. Most likely cause: Vitamin B12 deficiency secondary to terminal ileal resection and compromised intestinal absorption. Considerations Evaluation of a child with suspected anemia involves performing thorough personal and family histories and a comprehensive physical examination. Anemia can result from a variety of disorders, including defective red blood cell production, hemolysis, or blood loss. Children who quickly lose a large amount of blood usually have a normocytic anemia; the cells are normal, but there are fewer of them. Hypothyroidism, trisomy 21, vitamin B12 deficiency, and folate deficiency often are associated with macrocytic anemia and a low reticulocyte count, as a result of inadequate bone marrow production. A macrocytic anemia also may be seen with active hemolysis, but usually this anemia is accompanied by an elevated reticulocyte count. Vitamin B12-mediated macrocytic anemia can occur as a result of dietary deficiency, malabsorption, or inborn errors of metabolism. A pure dietary deficiency is rare in children, but diets devoid of all animal products may result in a deficiency. Breast-fed infants of mothers who adhere to a strict vegan diet are at risk for vitamin B12 deficiency. Malabsorption can occur when the terminal ileum is absent, as in this case scenario, or when infectious or inflammatory conditions compromise intestinal function. Children with the rare condition "juvenile pernicious anemia" are unable to secrete intrinsic factor and become vitamin B12 deficient between the ages of 1 and 5 years, when the supply of vitamin B12 passed transplacentally from mother to child is exhausted. These children will exhibit worsening irritability, loss of appetite, and decreased activity. Children affected with this condition are at risk for permanent neurologic damage resulting from spinal cord demyelinization. Highdose oral replacement may be corrective (limited, inconclusive studies at present) in patients with intrinsic factor deficiency or severe dietary deficiency that cannot be corrected with dietary modification. The fish tapeworm Diphyllobothrium latum uses vitamin B12, and intestinal infestation can result in macrocytic anemia. Similarly, any intestinal infectious or inflammatory process, such as parasitic infection or inflammatory bowel disease, could promote vitamin B12 deficiency. Eradicating or suppressing a gastrointestinal infection or inflammatory disorder should promote sufficient mucosal repair to permit adequate vitamin B12 absorption and further vitamin B12 therapy may not be required. For patients with an inability to produce intrinsic factor and for those with absence or permanent dysfunction of the gastric antrum or terminal ileum (the site of intrinsic factor production and absorption, respectively) monthly parenteral vitamin B12 therapy is indicated. For patients with macrocytosis but normal B12 and folate levels, consideration for atypical bone marrow pathology (such as leukemia or myelodysplasia) must be entertained. You are also told that the white blood cell count is 8500/mm3 and the differential reveals 47% neutrophils and 42% lymphocytes, and that no atypical lymphocytes are seen. The parents also report she has appeared weak and listless over the last several months, and has not been eating well. A 16-year-old adolescent female comes to your office for an evaluation of lethargy. During the last few years, she has helped her mother in the family seafood restaurant after school, but is increasingly tired and unable to complete all of her work.

Decreased perfusion of tissues by oxygen-carrying blood erectile dysfunction and diabetes a study in primary care 260 mg extra super avana with amex, which occurs in cardiac failure erectile dysfunction treatment adelaide order extra super avana 260mg with mastercard, hypotension, and shock 5. Cellular swelling, or hydropic change, is characterized by the presence of large vacuoles in the cytoplasm. Swel l i ng of the endoplasmic reticulum is one of the first ultrastructural changes evident in reversible injury. Swelling of the mitochondria progresses from reversible, low-amplitude swelling to irre versible, high-amplitude swelling, which is characterized by marked dilation of the inner mitochondrial space. Stimulation of phosphofructokinase activity results in increased glycolysis, accumulation of lactate, and decreased intracellular pH. Hypoxic cell injury eventually results in membrane damage to plasma and to lysosomal and other organelle membranes, with loss of membrane phospholipids. Myelin figures, whorl-like structures probably originating from damaged membranes b. Cell blebs, a cell surface deformity most likely caused by disorderly function of the cellular cytoskeleton D. The point of no return is marked by irreversible damage to cell membranes, leading to massive calcium i nfl ux, extensive calcification of the mitochondria, and cell death. I ntracellular enzymes and various other proteins are released from necrotic cells into the cir culation as a consequence of the loss of integrity of cell membranes. This phenomenon is the basis of a number of useful laboratory determinations as indicators of necrosis. Important examples include the troponins (troponin I [TnI] and troponin T [TnT]) and myoglobin. Purkinje cells ofthe cerebellum and neurons of the hippocam pus are more susceptible to hypoxic injury than are other neurons. Examples include the activated products of oxygen reduction, such as the superoxide B. Oxygen toxicity, such as in the alveolar damage that can cause adult respiratory distress jiJ 3. Intracellular enzymes, such as glutathione peroxidase, catalase, or superoxide dismutase jiJ 2. Exogenous and endogenous antioxidants, such as vitamin A, vitamin C, vitamin E, cysteine, glutathione, selenium, ceruloplasmin, or transferrin 3. Widespread injury results, including: Failure of the cell to synthesize the apoprotein moiety of lipoproteins causes an accumulation of intracellu lar lipids (fatty change). Plasma membrane damage, caused by products of lipid peroxidation in the smooth endo plasmic reticulum, resulting in cellular swelling and massive influx of calcium, with resultant mitochondrial damage, denaturation of cell proteins, and cell death v. Necrosis is the sum of the degradative and inflammatory reactions occurring after tissue death caused by injury. In pathologic specimens, fixed cells with well-preserved morphology are dead but not necrotic. Autolysis refers to degradative reactions in cells caused by intracellular enzymes indige nous to the cell. Postmortem autolysis occurs after the death of the entire organism and is not necrosis. Heterolysis refers to cellular degradation by enzymes derived from sources extrinsic to the cell. Coagulative necrosis Coagulative necrosis results most often from a sudden cutoff of blood supply to an organ (ischemia), particularly the heart and kidney. General preservation of tissue architecture is characteristic in the early stages. Nuclear changes, the morphologic hallmark of irreversible cell injury and necrosis, are characteristic. Suppurative infections characterized by the formation of pus (liquefied tissue debris and neutrophils) by heterolytic mechanisms involve liquefactive necrosis. Caseous necrosis combines features of both coagulative necrosis and liquefactive necrosis. This type of necrosis most often affects the lower extremities or bowel and is secondalY to vascular occlusion. When complicated by infective heterolysis and consequent liquefactive necrosis, gan grenous necrosis is called wet gangrene.

Next step in evaluation: Obtain a thorough history and review of systems erectile dysfunction questions to ask order 260mg extra super avana with mastercard, focusing on sexual history and symptoms consistent with possible extragenital infection encore erectile dysfunction pump discount 260 mg extra super avana visa. Gonorrheal and chlamydial acquisition rates historically increase as adolescents age, and recurrence rates can be as high as 40%. Questions should include whether dysuria, frequency, discharge, or changes in urine appearance have been noted. Rashes elsewhere on the body also should be investigated; the transient, pustular rash associated with disseminated gonococcal infection or the macular rash on the palms of patients with secondary syphilis could be identified. Importantly, more than 60% of urethritis patients are asymptomatic, and only about one-third will have frank dysuria or discharge. Chlamydial urethritis tops the differential diagnosis; other possibilities include gonococcal urethritis and Ureaplasma urealyticum or Mycoplasma genitalium infections. Dysuria caused by an inflammatory process involving the penile epidermis, rather than mucosa, should be included in the differential diagnosis (candidal balanitis, inflamed condyloma). A vaginal swab for culture is included if a pelvic examination already is planned to evaluate the female patient. Standard therapies for specific infections are widely available and should be consulted as sensitivity patterns change. Chlamydia therapy choices include one dose of azithromycin (Zithromax) or a 1-week course of doxycycline (Vibramycin) or erythromycin (E. Tubo-ovarian scarring and infertility in the female patient are possible, even when she is asymptomatic. Prior chlamydial infection carries a twofold increased risk for ectopic pregnancy. There has been no abnormal vaginal bleeding, with her last menses approximately 3 weeks ago. She is afebrile, but has left lower quadrant and suprapubic abdominal pain on deep palpation and minimal guarding. For the past few days, a 12-year-old boy has been complaining of an irritated and itchy penis and burning on urination. His mother noted a whitishyellow staining of his underwear yesterday when she was doing the laundry. He is an uncircumcised boy without penile or scrotal lesions, other than marked erythema of the glans penis with whitish coronal exudate upon foreskin retraction. Herpes genitalis A 17-year-old adolescent female presents with severe pain in the right upper quadrant and has some pain in her right shoulder. On physical examination, you confirm pain over the gallbladder, but also notice that she has right lower quadrant abdominal pain. Her pelvic examination is significant for discharge from the cervical os and pain upon cervical motion. Pelvic ultrasonography may be required if the physical examination proves equivocal. The potential for bacterial or fungal overgrowth in the uncircumcised male is approximately 30% greater than for circumcised males. In this patient with candidiasis, a topical treatment with an antifungal (clotrimazole) would be reasonable. The right upper quadrant pain results from ascending pelvic infection and inflammation of the liver capsule and diaphragm. It can mimic other abdominal emergencies and must be considered in sexually active adolescents as a diagnosis of exclusion. This condition was once thought to be caused only by N gonorrhoeae; C trachomatis infection probably is more common. The acute phase is described above and in the question; a chronic phase of persistent right upper quadrant pain or complete resolution of symptoms can also be seen. Other possible etiologies for this benign urethritis include chemical irritants (soaps), fabrics (rayon), and drying agents (powders). Treatment typically entails eliminating the offending agent and waiting for symptoms to subside. Clinical Pearls the goals of evaluating urethritis are to diagnose and treat infections that can threaten the viability of reproductive organs or cause extragenital or systemic infection. Typical sexually transmitted diseases may present atypically or in combination, making patient and partner history, focused examination, and casespecific testing important tools. Irritated genitourinary lesions or chemical urethritis can promote dysuria with scant or no findings on examination or urinalysis.
