A decrease in the number of red blood cells and, therefore, the hemoglobin concentration of the blood. If severe, anemia can cause a pale complexion, weakness, fatigue and shortness of breath on exertion. Any substance that causes the body to make an immune response against that substance. Antigens include toxins, chemicals, bacteria, viruses, or other substances that come from outside the body. This procedure is also used to remove circulating blood stem cells, which can be frozen, stored and used later for transplantation instead of bone marrow stem cells. A procedure in which stem cells are removed from a cancer patient, stored, and then given back to the patient after the patient undergoes intensive chemotherapy with or without radiation therapy. A specialized white cell that produces antibodies in response to any foreign substance, and especially to bacteria, viruses and fungi. There are three types of lymphocytes, which are a vital part of the immune system and are important in defense against infection. The spongy tissue in the hollow central cavity of the bones that is the site of blood cell formation. In adults, the bones of the hands, feet, legs and arms do not contain blood-forming marrow because in these sites the marrow is flled with fat cells. A central venous access device used to take blood samples and to administer therapies, medications, and other treatments to patients directly into a vein (intravenously). A thin tube is inserted and guided into a large vein, usually below the collarbone. A central venous catheter may stay in place for weeks or months to avoid the need for repeated needle-sticks. The use of chemicals (drugs or medications) to stop the growth of cancer cells by either killing the cancer cells or by stopping them from dividing. Stem cells that are present in blood that is drained from the placenta and umbilical cord. A method of freezing and storing cells, tissues or organs to save them for future use. Electrolytes are minerals in the blood and other bodily fuids that carry an electric charge. Common electrolytes include calcium, chloride, magnesium, phosphorus, potassium and sodium. The concentration of electrolytes in the bloodstream can be measured by diferent blood tests. Electrolytes afect body functions in many ways, including the amount of water in the body, the acidity of the blood (pH), muscle function and other important processes. A type of white blood cell that participates in allergic reactions and helps fght certain parasitic infections. A condition caused when stem cells from a donor (the graft) attack the healthy tissue of the transplant patient (the host). The principal sites of injury to the patient are the skin, the liver and the gastrointestinal tract. A type of white cell that has a large number of prominent granules in the cell body. A haploidentical transplant is a type of allogeneic stem cell transplantation that uses healthy, blood-forming cells from a half-matched donor to replace the unhealthy ones. Parents are always half-match donors for their children, and siblings have a 50 percent chance of being a half-match donor for each other. This person is either a specialist who treats adults or a pediatric hematologist who treats children. The stem cells begin to develop into young or immature blood cells such as red blood cells or white blood cells of various types. The reason for this activity is that most blood Blood and Marrow Stem Cell Transplantation I 51 cells live for short periods and must be steadily replaced. Red blood cells die in 4 months, platelets in 10 days and most neutrophils in 1 to 3 days. When the bone marrow is invaded with cancer cells, the constant demand for new blood cells cannot be met, resulting in a severe defciency in blood cell counts. Human leukocyte-associated antigens testing of a potential donor is done before a donor stem cell or organ transplant, to fnd out if there is a tissue match between the donor and the person receiving the transplant. A condition in which the skin and the whites of the eyes become yellow and the urine darkens. Small structures, usually less than 1 centimeter that contain large numbers of lymphocytes and are connected with each other by small channels called lymphatics. A type of white blood cell that constitutes about 5 to 10 percent of the cells in normal human blood. Monocytes and neutrophils are the two major microbe-eating and microbe-killing cells in the blood. When monocytes leave the blood and enter the tissue, they are converted to macrophages. The macrophage is the monocyte-in-action: It can combat infection in the tissues, ingest dead cells (in this function, it is called a scavenger cell?) and assist lymphocytes in their immune functions. A decrease below normal in the number of blood neutrophils, a type of white blood cell. Often, it is not present in sufcient quantities in patients with acute leukemia or after chemotherapy, thus increasing their susceptibility to infection. An oncologist has special training to treat cancer in adults, and pediatric oncologists are specially trained to treat cancer in children. These doctors cooperate and collaborate to provide the best treatment plan (surgery, radiation therapy, chemotherapy or immunotherapy) for the patient. Any unusual infection to which patients treated for cancer may be susceptible because of the suppression of their immune system. The word opportunistic is used to describe infections caused by bacteria, viruses, fungi or protozoa to which individuals with a normal immune system are not usually susceptible, but patients undergoing transplant have weakened immune systems and infections are more likely to occur. A hematopathologist is a type of pathologist who studies diseases of blood cells by examining peripheral blood smears, bone marrow aspirates and biopsies, and lymph nodes and other tissues and uses his or her expertise to identify diseases. A hematopathologist uses the information gathered from examining tissue samples under the Blood and Marrow Stem Cell Transplantation I 53 microscope together with laboratory values, fow cytometry fndings and molecular diagnostic test results to make the most accurate diagnosis.

Predictors of scarring and blindness for trachoma include increasing age and constant, severe trachoma. Screening for nonviral sexually transmitted infections in adolescents and young adults. Diagnosis of ocular trachoma usually is made clinically in countries with endemic infection. A diagnosis of C trachomatis infection in an infant should prompt treatment of the mother and her sexual partner(s). The need for treatment of infants can be avoided by screening pregnant females to detect and treat C trachomatis infection before delivery. For children 8 years and older, the recommended regimen is azithromycin, 1 g, orally, in a single dose, or doxycycline, 100 mg, orally, twice a day for 7 days. For pregnant females, the recommended treatment is azithromycin (1 g, orally, as a single dose). Test-of cure is not recommended for nonpregnant adult or adolescent patients treated for uncomplicated chlamydial infection unless compliance is in question, symptoms persist, or reinfection is suspected. Mothers of infected infants and mothers sexual partners should be treated for C trachomatis. Azithromycin typically is given to children in a community up to 14 years of age to 1 decrease the reservoir of active trachoma. Four naturally occurring forms of human botulism exist: infant, foodborne, wound, and adult intestinal colonization. Cases of iatrogenic botulism, which result from injection of excess therapeutic botulinum toxin, have been reported. Onset of symptoms occurs abruptly within hours or evolves gradually over several days and includes diplopia, dysphagia, dysphonia, and dysarthria. Some reports suggest that sudden infant death could result from rapidly progressing infant botulism. C botulinum spores are ubiquitous in soils and dust worldwide and have been isolated from the home vacuum cleaner dust of infant botulism patients. During the last decade, self-injection of contaminated black tar heroin has been associated with most cases. For wound botulism, the incubation period is 4 to 14 days from time of injury until onset of symptoms. To increase the likelihood of diagnosis in foodborne botulism, all suspect foods should be collected, and serum and stool or enema specimens should be obtained from all people with suspected illness. Because results of laboratory bioassay testing may require several days, treatment with antitoxin should be initiated urgently for all forms of botulism on the basis of clinical suspicion. Meticulous supportive care, in particular respiratory and nutritional support, constitutes a fundamental aspect of therapy in all forms of botulism. Antimicrobial therapy is not prescribed in infant botulism unless clearly indicated for a concurrent infection. Aminoglycoside agents can potentiate the paralytic effects of the toxin and should be avoided. Antibiotic agents may be given to patients with wound botulism after antitoxin has been administered. The role of antimicrobial therapy in the adult intestinal colonization form of botulism, if any, has not been established. Immediate reporting of suspect cases is particularly important, because a single case could be the harbinger of many more cases, as with foodborne botulism, and because of possible use of botulinum toxin as a bioterrorism weapon. Physicians treating a patient who has been exposed to toxin or is suspected of having any type of botulism should contact their state health department immediately. People exposed to toxin who are asymptomatic should have close medical observation in nonsolitary settings. Time, temperature, and pressure requirements vary with altitude and the product being heated. Food containers that appear to bulge may contain gas produced by C botulinum and should be discarded. Other foods that appear to have spoiled should not be eaten or tasted nchfp. Crepitus is suggestive but not pathognomonic of Clostridium infection and is not always present. These organisms are large, gram-positive, spore-forming, anaerobic bacilli with blunt ends. Other Clostridium species (eg, Clostridium sordellii, Clostridium septicum, Clostridium novyi) also have been associated with myonecrosis. Disease manifestations are caused by potent clostridial exotoxins (eg, C sordellii with medical abortion and C septicum with malignancy). The sources of Clostridium species are soil, contaminated foreign bodies, and human and animal feces. Nontraumatic gas gangrene occurs rarely in immunocompromised people and most often is described in those with underlying malignancy, neutrophil dysfunction, or diseases associated with bowel ischemia. Because Clostridium species are ubiquitous, their recovery from a wound is not diagnostic unless typical clinical manifestations are present. A Gram-stained smear of wound discharge demonstrating characteristic gram-positive bacilli and few, if any, polymorphonuclear leukocytes suggests clostridial infection. Because some pathogenic Clostridium species are exquisitely oxygen sensitive, care should be taken to optimize anaerobic growth conditions. Clindamycin, metronidazole, meropenem, ertapenem, and chloramphenicol can be considered as alternative drugs for patients with a serious penicillin allergy or for treatment of polymicrobial infections. Mild to moderate illness is characterized by watery diarrhea, low-grade fever, and mild abdominal pain. Pseudomembranous colitis is characterized by diarrhea with mucus in feces, abdominal cramps and pain, fever, and systemic toxicity. Disease often begins while the child is hospitalized receiving antimicrobial therapy but can occur up to 10 weeks after therapy cessation. The illness usually, but not always, is associated with antimicrobial therapy or prior hospitalization. The predictive value of a positive test result in a child younger than 5 years is unknown, because asymptomatic carriage of toxigenic 1American Academy of Pediatrics, Committee on Infectious Diseases. Metronidazole should not be used for treatment of a second recurrence or for chronic therapy, because neurotoxicity is possible. No comparisons to metronidazole are available, and no pediatric data are available. The most effective means of preventing hand contamination is the use of gloves when caring for infected patients or their environment, followed by hand hygiene after glove removal. Necrotizing colitis and death have been described in patients with Type A Clostridium taking medications resulting in constipation. C perfringens type B, which produces e toxin, a neurotoxin, has been proposed as an environmental trigger for multiple sclerosis. Ingestion of the organism is most commonly associated with foods prepared by restaurants or caterers or in institutional settings (eg, schools and camps) where food is prepared in large quantities, cooled slowly, and stored inappropriately for prolonged periods. Although C perfringens is an anaerobe, special transport conditions are unnecessary. Pleural effusion, empyema, and mediastinal involvement are more common in children. Acute infection may be associated only with cutaneous abnormalities, such as erythema multiforme, an erythematous maculopapular rash, or erythema nodosum. Chronic pulmonary lesions are rare, but approximately 5% of infected people develop asymptomatic pulmonary radiographic residua (eg, cysts, nodules, cavitary lesions, coin lesions). Cutaneous lesions and soft tissue infections often are accompanied by regional lymphadenitis. In soil, Coccidioides organisms exist in the mycelial phase as mold growing as branching, septate hyphae. Infectious arthroconidia (ie, spores) produced from hyphae become airborne, infecting the host after inhalation or, rarely, inoculation. In tissues, arthroconidia enlarge to form spherules; mature spherules release hundreds to thousands of endospores that develop into new spherules and continue the tissue cycle.

Bergh J, Marklund I, Gustavsson C, Wiklund F, Gronberg H, Allard A, Alexeyev O, Elgh F. Alexeyev O, Bergh J, Marklund I, Thellenberg-Karlsson C, Wiklund F, Gronberg H, Bergh A, Elgh F. Propionibacterium acnes infection induces up regulation of inflammatory genes and cytokine secretion in prostate epithelial cells. Chronic prostatic infection and inflammation by Propionibacterium acnes in a rat prostate infection model. Propionibacterium acnes induces chronic inflammation and precancerous epithelial lesions in the dorso-lateral prostate in rats. Its aetiology is largely unknown, but as it is estimated that about 20% of all human cancers are caused by chronic infection 1, it is possible that microorganisms could play a role also in the pathogenesis of prostate cancer. Prostatitis, caused by infectious agents, but also by other factors, is a very common finding in men of all ages and this inflammation is preferably seen in the parts of the prostate where cancer is detected in elderly men 2. The question whether prostate cancer can be induced by chronic inflammation, and if so, what the causes for this cancer promoting inflammation are, is largely unanswered. The Prostate A small organ with few essential functions but the centre of many common diseases 1. It is located anterior to the rectum distal to the urinary bladder and wraps around the urethra. Due to its anatomical position, infectious agents can reach the prostate mainly through the urine or as ascending sexually transmitted infections. The normal prostate has the same size and shape as a walnut and it mainly consists of tubuloalveolar glands that empty their secretions into the urethra. In humans the prostate is divided into three different zones; the peripheral, the central and the transitional zone 4. The peripheral zone, located posterior to the urethra and ejaculatory ducts, comprises the majority (65%) of the prostate volume and is the part of the gland were 70% of all prostate cancer originates 5, 6. The central zone constitutes approximately 25% of the normal prostatic volume and is rarely affected by carcinoma or inflammation. There is no clear-cut homology between specific rodent prostate lobes and human prostatic zones but it has been observed that neoplasms are usually derived from the dorso-lateral lobe in rodents 9, 10 and has therefore been proposed to be corresponding to the peripheral zone 11, 12. Gene expression analysis also support the idea that the dorso-lateral lobe is most similar to the peripheral zone of the human prostate 13. Histology the prostate consists of two basic structures; glands and fibromuscular stroma. The glands consist of three fully differentiated cell types; basal epithelial, luminal epithelial and neuroendocrine cells. The basal cells rest on the basement membrane and harbour a small number of stem cells 14. These stem cells proliferate and give rise to basal, luminal or neuroendocrine cells. The differentiation to luminal cells is believed to occur through an intermediate phenotype, expressing markers specific for both basal and luminal epithelial cells 15, 16. In contrast to the basal cells, the secretory luminal cells are terminally differentiated and have limited capacity to divide. The fibromuscular stroma is made up of smooth muscle cells, fibroblasts, blood vessels, nerves, lymphatics and infiltrating immune cells. The stroma gives physical support to the glandular epithelium, enables contraction and mediates release of growth factors that regulate epithelial growth and homeostasis. Function the main function of the prostate is to synthesise and secrete the proteins and fluid that, together with contributions from the seminal vesicles, form most of the ejaculate. Although the prostate is involved in fertility, it is not 2 required for reproduction. The prostate is also known to produce antimicrobial products such as zinc, lysozyme and defensins 22, 23. Regulation the prostate is dependent on androgens for development, growth and function. Testosterone, the main circulating androgen, is produced in the testes by the Leydig cells. When the supply of androgens is lost, the prostate luminal epithelial cells will undergo apoptosis, resulting in involution of the prostate gland 27-29. However, both stromal and basal epithelial cells are maintained during castration 30, 31. Prostate disorders Three different and very common diseases affect the prostate: prostatitis, benign prostatic hyperplasia and prostate cancer. It affects men of all ages and it is estimated that about 50% of all men will experience symptoms of prostatitis at some time during their lives 37. It is the most common urological disorder in men under the age of 50 and the third most common urological disorder, after benign prostatic hyperplasia and prostate cancer, in men older than 50 38. Common symptoms include pain (genitourinary, pelvic, or rectal), voiding symptoms and sexual dysfunction. Other common organisms include Proteus mirabilis, Pseudomonas aeruginosa and Klebsiella. Diagnosis is based on symptoms, physical examination, urine culture and/or urine culture after prostatic massage. Bacterial prostatitis is treated with antibiotics, preferably a fluoroquinolone, because of their good prostate penetration and activity against most usual bacterial pathogens 43. The clinical symptoms result from compression of the prostatic urethra and consequent obstruction of the bladder outlet. Men that have suffered from prostatitis have a greater risk to later develop benign prostatic hyperplasia64, 65. Epidemiology Prostate cancer is the most common cancer in Sweden with an incidence of 9697 per year (2010) (The National Board of Health and Welfare). In the last 5 years, the incidence has slightly decreased indicating that the peak is reached. Prostate cancer mortality is almost unchanged during these years with 2460 deaths (2010) annually. Men diagnosed with prostate cancer are on average 70 years old, while the majority of prostate cancer deaths occur in men over 79 years. Interestingly, the number of men diagnosed with advanced, metastatic disease, have declined the last years indicating that more men are potentially curable. Today approximately 75 000 men in Sweden are living with a prostate cancer diagnosis, but autopsy studies indicate that asymptomatic prostate cancer is actually present in more than 50% of men in their 5th decade or older 66. Worldwide, the highest incidence of prostate cancer is seen in Western countries and in some African regions and the lowest incidence is seen in Asian countries 67. The highest incidence of prostate cancer death is seen in African-Americans and the second highest risk of dying in prostate cancer is seen in Sweden. The explanation to variations in both incidence and mortality in prostate cancer around the world is not known, although genetic, environmental and socioeconomic factors could all be of importance 68. Their differention pattern, ranging from 1 to 5, were 5 represents the lowest differentiated and most aggressive tumour pattern, grade the tumour glands. The most common and the second most common grade is summarised into the Gleason score (2-10). Tumours with Gleason score <6 have a good prognosis whereas tumours with Gleason score >8 are associated with an unfavourable outcome. In patients with Gleason score 6 and 7, which constitute about 75% of cases diagnosed outcome is highly variable and at present largely unpredictable 70. If the life expectancy of the patient is short and the tumour is at an early stage it is common that the patient is only subjected to watchful waiting (no treatment until symptoms of metastases) or active monitoring (treatment when signs of tumour progression are detected). Advanced prostate cancer is characterized by dissemination of prostate cancer cells, typically to lymph nodes and bone. For advanced and metastatic prostate cancer there is no cure and the therapy is palliative with surgical or chemical castration.
