Criminal Justice System the criminal justice system routinely fails to provide justice to victims of violent crimes and human rights violations allergy ucsf cheap beconase aq 200mdi with mastercard. Causes of failure include corruption allergy symptoms from grass order beconase aq 200mdi, inadequate training and resources allergy forecast chapel hill nc beconase aq 200mdi low price, and complicity of prosecutors and public defenders with criminals and abusive officials allergy testing cats buy generic beconase aq 200mdi on-line. In 2013, Mexico enacted a federal victims law intended to ensure justice, protection, and reparations for crime victims. Reforms aimed at reducing bureaucracy and improving access to reparations were approved in January 2017. Torture Torture is widely practiced in Mexico to obtain confessions and extract information. It is most frequently applied in the period between when victims are detained, often arbitrarily, and when they are handed over to civilian prosecutors-a period in which they are often held incommunicado at military bases or illegal detention sites. In addition, 28 percent reported that they were threatened that their family would be harmed. In 2014, Congress reformed the Code of Military Justice to require that abuses committed by members of the military against civilians be handled by the civilian criminal justice system rather than the military system, which had a history of failing to hold members of the military accountable for abuses. In May, a federal judge established that prosecutors had not adequately investigated evidence of torture of detainees in the Ayotzinapa case. At least 10 government agencies filed appeals against the ruling, which, at time of writing, remained pending. In April 2017, the Mexican legislature approved the Law to Investigate, Prevent, and Sanction Torture, aimed at curbing torture and excluding testimony obtained through torture from judicial proceedings. The council also criticized the lack of coordination between institutions, and expressed its concern that most states lag behind in implementing the law. The former director of forensic services stated that authorities had used refrigeration trailers for at least two years to store more than 250 bodies. The human rights prosecutor asserted that authorities had taken proper information and samples to enable identification of only 60 bodies. Enforced Disappearances Since 2006, enforced disappearances by security forces has been a widespread problem. In October 2018, the interior minister stated that the whereabouts of more than 37,400 people who had gone missing since 2006 remain unknown. As of August 2018, it had opened 1,255 investigations but only pressed charges in 11 cases. In November 2017, Congress passed a law on disappearances that established a single nationwide definition for the crime and mandated the creation of entities to facilitate the investigation and prosecution of disappearances. Government authorities only register the number of homicides and not the circumstances in which these took place. The Defense Department stopped registering the numbers of civilians it killed as of 2014. Some provisions, including those that make the severity of punishments for some sexual offenses contingent upon the "chastity" of the victim, contradict international standards. Although the Supreme Court ruled in 2010 that all states must provide emergency contraception and access to abortion for rape victims, many women and girls face serious barriers accessing abortions after sexual violence, including official intimidation. Attacks on Journalists Journalists, particularly those who report on crime or criticize officials, often face harassment and attack by both government authorities and criminal groups. A 2017 study by researchers from the University of Miami and the Iberoamerican University in Mexico City showed that almost 70 percent of journalists said they had engaged in self-censorship out of fear for their personal safety. Media reports indicated that eight journalists were killed between January and September 2018. In 2012, the federal government established the National Protection Mechanism to issue and coordinate the implementation of protective measures for journalists and human rights defenders under threat. Between October 2012 and July 2018, 418 journalists requested and 357 were authorized to receive protection measures. However, protection has been slow to arrive and, in some cases, has been insufficient. Authorities routinely fail to investigate crimes against journalists adequately, often preemptively ruling out their profession as a motive. As of August 2018, it brought charges in 152 cases and obtained only seven convictions, of which just one was for homicide. Migrants and Asylum Seekers Migrants traveling through Mexico are frequently subject to abuses and human rights violations. In some of these cases there are allegations that government authorities are involved. According to government statistics, apprehensions of unaccompanied children from the Northern Triangle countries of El Salvador, Guatemala, and Honduras were significantly lower in 2017 and 2018 compared to 2016, and asylum recognition rates for unaccompanied children from these countries have risen in recent years. It also urged the state to guarantee the rights of migrants in transit and called on Mexican authorities to "only use the detention of migrants as a measure of last resort," to improve conditions of detention, and to "immediately put an end to" the detention of migrant children. Sexual Orientation and Gender Identity Mexico City and 11 additional states have legalized same-sex marriage. In other states, same-sex couples must file a constitutional challenge (amparo) to be allowed to marry; a 2015 Supreme Court decision holding that the definition of marriage as being only between a man and a woman violates the constitution, means that rulings in such cases should be in their favor. In October 2018, the Supreme Court ruled in favor of a transgender applicant who sought to change their gender marker through administrative means at the Civil Registry in Veracruz. The ruling, which cited an Inter-American Court on Human Rights advisory opinion on the right to legal gender recognition, suggested the court might uphold transgender rights in an upcoming case that may create binding jurisprudence. Mexico made no progress in implementing the right to legal capacity for persons with disabilities. In June, a Casablanca court sentenced leaders of the "Hirak," a protest movement that demonstrated regularly in the Rif region for months, to sentences of up to 20 years in prison after unfair trials. A court sentenced a prominent journalist and government critic to three years in prison on a dubious security charge, while he was already serving a sentence for inciting unauthorized demonstrations. Laws on violence against women and on domestic work took effect in the fall, offering modest new protections to victims of violence and labor abuse. In one incident captured on video, a police vehicle on March 14 sped into a protest, hitting 16-yearold Abdelmoula Zaiqer and severely injuring him. Police agents broke into houses without showing warrants, beat several men upon arrest, and broke doors and windows, local activists and a lawyer said. Between March 14 and May 31, authorities arrested and prosecuted at least 69 protesters in Jerada; four protest leaders received between three and nine months in prison. The "Hirak," a socioeconomic protest movement in the Rif region that started in 2016, staged several largely peaceful mass protests until a police crackdown in May 2017 led to the arrest of more than 450 activists. The charges included rebellion, violence against police forces, staging unauthorized protests, and receiving foreign funding. On September 25, the coastguard fired on a boat in the Mediterranean, killing student Hayat Belkacem, 20, and wounding three other passengers, who were apparently trying to migrate to Europe. Authorities pledged to investigate the killing but had not disclosed their findings at time of writing. The dispersals, the ministry said, were conducted in a manner consistent with the "respect of basic freedoms and the rule of law. The Code of Penal Procedure gives a defendant the right to contact a lawyer after 24 hours in police custody, extendable to 36 hours. But detainees do not have the right to a have a lawyer present when police interrogate or present them with their statements for signature. In a typical instance, on March 12, security forces in the city of Beni Mellal blocked the entrance of a community center where the local branch had planned a conference. The government has continued to impose a de facto ban on research missions by Amnesty International since 2015, despite relatively unimpeded access of the organization for nearly 25 years before then. Human Rights Watch researchers were able to conduct research missions in 2018 to Jerada and El-Ayoun in Western Sahara, but were frequently followed by cars containing men in civilian clothes. On June 28, a Casablanca court of first instance sentenced journalist Hamid El Mahdaoui to three years in prison for failing to report a security threat.
Heavy infection in children allergy wiki buy beconase aq 200mdi amex, especially those who are already malnourished allergy to sunscreen cheap beconase aq 200mdi on line, may have significant effects on nutrition and development allergy desensitization generic 200mdi beconase aq with amex. Serious morbidity and mortality are rare in ascariasis allergy shots cluster cheap 200mdi beconase aq with mastercard, but the huge number of people infected means that, on a global basis, roundworm infection causesasignificantburdenofdisease,especiallyinchildren.

Ova can becollected either by usingamoistenedperianalswab, orby applying adhesive cellophanetapetotheperianalskin. Whipworm(Trichuristrichiura) Infections with whipworm are common worldwide, especially in poor communities with inadequate sanitation. Infection is usually asymptomatic, but mucosal damage can occasionallybe so severe that thereiscoloniculceration,dysenteryorrectalprolapse. Diagnosis is made by finding ova on stool microscopy, or occasionally by seeing adult wormsonsigmoidoscopy.

Strongyloidiasis Strongyloides stercoralis is a small (2mm long) worm that livesin the small intestine. It is found in many parts of the tropics and subtropics, and is especially common in Asia. Usually, these are non-infective rhabditiform larvae, which require a further period of maturation in the soil before they can infect a new host, but sometimes this maturation can occur in the large bowel. Infective filariform larvae can therefore penetrate directly through the perianal skin, re-infecting the host. Diagnosisandmanagement Motile larvae may be seen on stool microscopy, especially after a period of incubation. Trichinosis the normal hosts of Trichinella spiralis, the cause of trichinosis, include pigs, bears and warthogs. Ingestedlarvae mature in the small intestine, where adults release new larvae that penetrate the bowel wall andmigratethroughthetissues. Heavierloadsofwormsproducegastrointestinal symptoms as the adults establish themselves in the small intestine, followed by systemic symptoms as the larvae invade. The diagnosis can usually be made from the clinical picture, associated eosinophilia and serological tests. Ocular infection may produce a granulomatous swelling mimicking a retinoblastoma, while cardiac or neurological involvement is occasionallyfatal. Isolation of the larvae is difficult and the diagnosis is usually made serologically. In humans, they are unable to complete a normal life cycle and instead migrateundertheskinfordaysorweeksuntiltheyeventuallydie. They have complex life cycles, often involving fresh-water snails and intermediate mammalian hosts. Chronic infection causes significant morbidity and, after malaria, it has the most socioeconomic impact of any parasitic disease.

Shaematobiuminfection(bilharzia) the earliest symptom is usually painless terminal haematuria. As bladder inflammation progresses, there is increased urinary frequency and groin pain. Obstructive uropathy develops, leading to hydronephrosis, chronic kidney disease and recurrent urinary infection. There is a strong association between chronic urinary schistosomiasis and squamous cell bladdercarcinoma. Early disease produces superficial mucosal changes, accompanied by blood-stained diarrhoea. Later, the mucosal damage becomes more marked, with the formation of rectal polyps, deeper ulceration and, eventually, fibrosis and stricture formation. Ectopic eggs are carried to the liver, where they cause an intense granulomatous response. Hepatitis is followed by progressive periportal fibrosis, leading to portal hypertension,oesophagealvaricesandsplenomegaly(seep.

Serological tests are available and may be useful in the diagnosis of travellers returning from endemic areas, although the test may not become positive for 12weeks after infection; a parasitological diagnosis should always be made, if possible.

The transfer of embryos is risky allergy quorn symptoms generic 200mdi beconase aq mastercard, and researchers are reluctant to put an endangered animal through the rigors of surrogate motherhood allergy symptoms of pancreatic cancer purchase beconase aq 200mdi fast delivery, opting to use nonendangered domesticated animals whenever possible allergy symptoms nasal congestion discount beconase aq 200mdi without prescription. Cloning extinct animals is even more challenging than cloning living animals because the egg and the surrogate mother used to create and harbor the cloned embryo are not the same species as the clone allergy forecast oregon order 200mdi beconase aq fast delivery. Furthermore, for most already extinct animal species such as the woolly mammoth or dinosaur, there is insufficient intact cellular and genetic material from which to generate clones. In the future, carefully preserving intact cellular material of imperiled species may allow for their preservation and propagation. The clone was created from a single skin cell, taken from another banteng before it died in 1980, which had remained frozen until it was used to create the clone. Born April 1, 2003, the cloned banteng developed normally, growing its characteristic horns and reaching an adult weight of about 1,800 pounds. Hunting and habitat destruction have reduced the number of banteng, which once lived in large numbers in the bamboo forests of Asia, by more than 75% from 1983 to 2003. In August 2005 the Audubon Nature Institute in New Orleans, Louisiana, reported that two unrelated endangered African wildcat clones had given birth to eight babies. Their births confirmed that clones of wild animals can breed naturally, which is vitally important for protecting endangered animals on the brink of extinction. At least some of the media frenzy resulted from the beliefs of the Raelians-namely, the sect contends that humans were created by extraterrestrial beings. In 2005 Clonaid claimed to have produced at least thirteen cloned children, but as of 2007 had not yet offered any proof of their existence. Another doctor focusing on fertility issues, Severino Antinori, attracted media attention when he maintained that hundreds of infertile couples in Italy and thousands in the United States had already enrolled in his human cloning initiative. Neither these researchers nor anyone else had offered proof of successful reproductive human cloning as of early 2007. The objective of therapeutic cloning is not to create clones but to obtain stem cells. Stem cells are ``master cells' capable of differentiating into multiple other cell types. This potential is important to biomedical researchers because stem cells may be used to generate any type of specialized cell, such as nerve, muscle, blood, or brain cells. Researchers believe that in the future it may be possible to induce stem cells to grow into complete organs. Advocates of therapeutic cloning point to other treatment benefits such as using stem cells to generate bone marrow for transplants. This would eliminate the problem of rejection of foreign tissue associated with bone marrow transplant and other organ transplantation. Stem cells also have the potential to repair and restore damaged heart and nerve tissue. Furthermore, there is mounting evidence to suggest that stem cells from cloned embryos have greater potential as medical treatments than stem cells harvested from unused embryos at fertility clinics, which are created by in vitro fertilization and are now the major source of stem cells for research. These prospective benefits are Cloning 109 among the most compelling arguments in favor of cloning to obtain embryonic stem cells. Stem cells used in research are harvested from the blastocyst after it has divided for five days, during the earliest stage of embryonic development. Many people regard human embryos as human beings or at least potential human beings and consider their destruction, or even using techniques to obtain stem cells that might imperil their future viability, as immoral or unethical. A skin cell was inserted inside each of eight enucleated eggs, which were then chemically stimulated to divide. Just three of the eight eggs began dividing, and only one reached six cells before cell division ceased. That same year investigators at the South Australian Research and Development Institute used lambs to experiment with therapeutic cloning. In 2003 researchers in Italy reported successfully using adult stem cells to cure mice that had a form of multiple sclerosis. The scientists injected the diseased mice with stem cells that had been extracted from the brains of adult mice reproduced in the laboratory. Postmortem examination of the mice showed that the stem cells had migrated to and then repaired damaged areas of the nerves and brain. In August 2003 a Chinese research team led by Huizhen Sheng, an American-trained scientist working at the Shanghai Second Medical University, reported that it had made human embryonic stem cells by combining human skin cells with rabbit eggs. Their accomplishment was published in the Chinese scientific journal Cell Research, a peer-reviewed publication of the Shanghai Institute of Cell Biology and the Chinese Academy of Sciences. In February 2004 scientists at Seoul National University in South Korea reported in the journal Science that they had successfully cloned healthy human embryos, removed embryonic stem cells, and grown them in mice. In January 2006, following a lengthy investigation, Seoul National University concluded that the research reported in Science had been fabricated. As a result, the journal retracted the article along with another study by the same author. By observing the stem cells grow into neurons, the researchers hope to discover what causes the cells to degenerate. Human reproductive cloning remains illegal in Britain but therapeutic cloning-creating embryos as a source of stem cells to cure diseases-is allowed on an approved basis. They published their results in ``Recovery from Paralysis in Adult Rats Using Embryonic Stem Cells' (Annals of Neurology, July 2006). Although clinical trials in humans are still years away, the results of this research represent an important advance in the quest for a cure for paralysis and other neurological disorders. The researchers anticipate testing these cells in animals in 2008 and if the animal studies are successful, then clinical trials in human patients may begin as soon as 2009. Lunde and his contributors found no benefit from stem cell treatment of such patients. Assmus and her collaborators studied patients with chronic heart failure, who did show improvement after treatment. In the editorial ``Cardiac Cell Therapy-Mixed Results from Mixed Cells' in the same issue of the journal, Antony Rosenzweig writes that the three studies ``provide a realistic perspective on this approach while leaving room for cautious optimism and underscoring the need for further study. The researchers acknowledged that their work showed both the promise and risks associated with stem cell treatments. Research Promises Therapeutic Benefits without Cloning but others caution that such research could heighten concerns among those who fear that stem cell technology will lead to the creation of ``designer babies,' which are bred for specific characteristics such as appearance, intelligence, or athletic prowess. Scholer selected from a population of stem cells the ones that bore certain genetic traits suggesting the potential to become eggs. The eggs matured normally and appeared to be healthy in terms of their appearance, size, and gene expression. When cultured for a few days, the eggs also underwent spontaneous division and formed structures resembling embryos, a process called parthenogenesis. This finding implies that the eggs were fully functional and likely could be fertilized with sperm. Once refined, this technology could be applied to produce egg cells in the laboratory that would enable scientists to engineer traits into animals and help conservationists rebuild populations of endangered species. It offers researchers the chance to observe mammalian egg cells as they mature, a process that occurs unseen within the ovary. The technology also offers an unparalleled opportunity to learn about meiosis (reduction division), the process of cell division during which an egg or sperm disgorges half of its genes so it can join with a gamete of the opposite sex. For example, women who cannot make healthy eggs could use this technology to ensure healthy offspring. Like many new technologies, transforming cells into eggs simultaneously resolves existing ethical issues and creates new ones. For example, because the embryonic stem cells spontaneously transformed themselves into eggs, this procedure overcomes many of the ethical objections to cloning, which involves creating offspring from a single parent. However, it also paves the way for the creation of ``designer eggs' from scratch and, if performed with human cells, could redefine the biological definitions of mothers and fathers.
It is not inactivated by most -lactamases and is less likely to induce -lactamase production allergy home remedies 200mdi beconase aq with amex. Ertapenem allergy testing vancouver wa cheap 200mdi beconase aq with amex, unlike the others allergy shots greenville nc discount 200mdi beconase aq visa, is not active against Pseudomonas or Acinetobacter spp allergy luxe buy beconase aq 200mdi without prescription. They are used for serious nosocomial infections when multidrugresistantGram-negativebacilliormixedaerobeandanaerobeinfectionsaresuspected. Even though it is poorly absorbed, prolonged oral administration can produce ototoxicity. They are highly effective against many Gram-negativeorganisms,includingPseudomonasspp. Netilmicin and amikacin have a similar spectrum but are more resistant to the aminoglycoside-inactivating enzymes (phosphorylating, adenylating or acetylating) produced bysomebacteria. Aminoglycosides are nephrotoxic and ototoxic (vestibular andauditory),particularlyintheelderly. Therapeutic drug monitoring is necessary to ensure therapeutic and non-toxic drug concentrations. These are bacteriostatic drugs possessing a four-ring hydronaphthacene nucleus. Tetracyclines are active against Gram-positive and Gram-negative bacteria but their use for the latter is limited due to bacterial resistance. Tetracyclines are generally safe drugs, but they may enhance established or incipient renal failure, although doxycycline is safer than others in this group. Erythromycinhasasimilar(butnotidentical)antibacterialspectrumto penicillin and may be useful in individuals with penicillin allergy, especially in the managementofbacterialrespiratoryinfections. Itcanbegivenorallyorparenterally,butoral intake is associated with significant gastrointestinal side-effects, while the intravenous formulationisveryirritantandcausesphlebitis. Forthesereasons,clarithromycin(whichhas similar antimicrobial properties but fewer side-effects) is often preferred. These drugs are preferred in the treatment of pneumonias caused by Legionella spp. They are also effective in the treatment of infections due to Bordetella pertussis (whooping cough),Campylobacterspp. They have a broad spectrum of activity that includesselectiveGram-negativeorganisms,mycobacteriaandToxoplasmagondii. Compared with erythromycin, they have superior pharmacokinetic properties with enhanced tissue and intracellular penetration and a longer half-life that allows once-daily dosage. Azithromycin is also used for trachoma, cholera and for some sexuallytransmittedinfections. Erythromycin and other macrolides interact with theophyllines, carbamazepine, digoxin and ciclosporin, occasionally necessitating dose adjustment of these agents. Diarrhoea,vomitingandabdominalpainarethemainside-effectsoferythromycin (less with clarithromycin and azithromycin) as a consequence of the intestinal prokinetic propertiesofthemacrolides. This structure probably accounts for its toxicity in humans and for its activity againstbacteria. Because of its adverse-effect profile (see below), chloramphenicol hadbeenlittleusedindevelopedcountriesformanyyears.

Sodium fusidate commonly causes gastrointestinal adverse effects and may occasionally be hepatotoxic; however, it is generally a safe drug and can be given during pregnancyifnecessary. Sulphonamides block thymidine and purine synthesis by inhibiting microbial folic acid synthesis. Becauseofitsadverseeffectprofile,useindevelopedcountrieswaslargely restricted to the treatment and prevention of Pneumocystisjiroveci infection and listeriosis, although it is increasingly being prescribed in hospitals again for other infections, such as acute exacerbations of chronic bronchitis and urinary tract infections, as it appears to be of relativelylowerriskfortriggeringC. Resistance to sulphonamidesis often plasmid-mediated and results from theproduction of sulphonamide-resistant dihydropteroate synthase from altered bacterial cell permeability to theseagents.

Trimethoprim is similar in molecular structure to the potassium-sparing diuretic amiloride;monitoringofrenalfunctionisrequiredwhenusingtrimethoprimorco-trimoxazole, particularly when the patient is prescribed other potassium-sparing drugs. Quinolones(ciprofloxacin,moxifloxacin,norfloxacin,ofloxacin,levofloxacin andgemifloxacin) these are useful oral broad-spectrum antibiotics, related structurally to nalidixic acid. Theextended-spectrumquinolonessuchasciprofloxacinhaveactivity against Gram-negative bacteria, including some Pseudomonas aeruginosa and some Grampositive bacteria. Gastrointestinal disturbances, photosensitive rashes and occasional neurotoxicity canoccur. Tendon damage, including rupture, can occur within48hoursofuseandthedrugshouldbestoppedimmediately;itshouldnotbegivenin patientswithtendonitis. Clinical experience with linezolid has demonstrated efficacy in a variety of hospitalized patients with severe to lifethreatening infections, such as bacteraemia, hospital-acquired pneumonia, and skin and soft tissueandboneandjointinfections. Thesedrugscanbegivenbothintravenouslyandbymouth, and are almost 100% bioavailable by the oral route in patients with normal gastrointestinal absorption. Side-effects include gastrointestinal disturbances, headache, rash, hypertension, reversible but potentially severe cytopenias, and occasional reports of optic and peripheral neuropathyinpatientsreceivinglinezolidforlongerthan28days. Metronidazole plays a major role in the treatment of anaerobic bacterialinfections,particularlythoseduetoBacteroidesspp. It may be given orally, by suppository (well absorbed and cheap) or intravenously(moreexpensive). Nitroimidazoles can produce a disulfiram-like reaction with ethanol and enhance the anticoagulant effect of warfarin; patients should be warned not to drink alcohol whilsttakingthem. Nitroimidazoles are tumorigenic in animals and mutagenic for bacteria, although carcinogenicity has not been described in humans. It is also used for treatment and prophylaxis against Gram-positive infections in penicillin-allergic patients. Bymouth,it is not absorbed from the gastrointestinal tract and is the preferred therapy for moderate to severe C. Vancomycin can cause ototoxicity and nephrotoxicity, and thus pre-dose (trough) serum levels should be monitored regularly. Serum levels at 1h post dose (peak) are also monitoredtooptimizedrugefficacy(seep. It has more favourable pharmacokinetic properties, allowing once-daily or thrice-weekly dosage.

Theemergenceofcarbapenemase-producingGram-negativebacteria,however, has resulted in increased use, often incombination with other antibioticssuch as tigecycline and high doses of carbapenems. The mechanism of bacterial killing is thought to be due to disruption of the bacterial cell membrane following binding to the lipopolysaccharide component. Nephrotoxicity is a major problem and dosage levels must take background renal function into account. Imidazoles, such as ketoconazole, miconazole and clotrimazole, are broadspectrum antifungal drugs. They are predominantly fungistatic and act by inhibiting fungal sterol synthesis, resulting in damage to the cell wall.

Metastatic disease to bone is common in advanced breast cancer, and most metastatic disease occurs in the central skeleton (vertebrae, pelvis, ribs, upper legs, and upper arms). This method is considered one of the four mature defense mechanisms, along with altruism, humor, and suppression. Displacement is an immature defense mechanism in which avoided ideas and feelings are transferred to a neutral person or object. An example of this is a woman who is angry at her boss and instead yells at her sister on the phone. Projection is an immature defense mechanism in which an unacceptable internal impulse is attributed to an external source. An example of this is a man who is attracted to another woman and accuses his wife of cheating on him. Reaction formation is an immature defense mechanism in which a warded-off idea or feeling is replaced by an unconsciously derived emphasis on its opposite. Suppression is another mature defense mechanism in which unwanted feelings are voluntarily (unlike other defenses) withheld from conscious awareness. An example of this is a patient with pancreatic cancer who decides that he will only think about his illness 15 minutes per day. Bisphosphonates, such as alendronate and risedronate, are used to treat metastatic bone diseases and osteoporosis. Bisphosphonates decrease pain and fractures by reducing the number and activity of osteoclasts and inhibiting bone resorption. Cephalosporins are b-lactam antibiotics used to treat infections caused by gram-positive and gram-negative bacteria. The vinca alkaloids, such as vincristine and vinblastine, are microtubule inhibitors used in the treatment of testicular carcinoma and Hodgkin and nonHodgkin lymphomas. Despite its potent bacteriostatic activity, chloramphenicol is now used rarely because of its toxicities (gray baby syndrome and aplastic anemia). Aplastic anemia with chloramphenicol use is a dosedependent adverse event that can occur after only a short course of therapy and can be fatal. Because it is inexpensive, chloramphenicol is often used in resource-limited settings overseas. Gentamicin binds to the 30S subunit and is associated with nephrotoxicity and ototoxicity with prolonged use. Erythromycin is associated with cholestatic hepatitis, eosinophilia, and skin rashes. Azithromycin, a related macrolide, is better tolerated and results in fewer adverse events. The sulfonamides act by inhibiting dihydropteroate synthetase, an enzyme involved in folate synthesis. They can cause serious allergic reactions, urinary tract disorders, and porphyria. Although the sulfonamides can cause aplastic anemia, it occurs far less frequently than with chloramphenicol. The more unique complications include tendonitis and tendon rupture in adults, and cartilage malformation in children and in the developing fetus. Clindamycin is classically associated with intestinal colonization by Clostridium difficile. This leads to pseudomembranous colitis, in which patients usually present with cramping, watery diarrhea, and a low-grade fever. This is characterized by pain symptoms that are inconsistent with physiological processes. There is typically a close temporal relationship with psychological factors, and such disorders are seen more commonly in females than males. Treatment typically includes rehabilitation, such as behavioral therapy, physical therapy, and psychotherapy. Group therapy is helpful for many psychiatric conditions, including hypochondriasis. In this disorder there is preoccupation with or fear of having a serious disease despite medical reassurance. This leads to significant distress and impairment, and often involves a history of prior physical disease. This patient has not described a preoccupation about her illness, so it is unlikely that she is suffering from hypochondriasis. Analgesia, including opioid treatment, is generally not indicated for pain disorder. Moreover, pain disorder may not resolve on its own once it has been persistent for several years. Patients with conversion disorder present with symptoms or deficits of voluntary or sensory function (eg, blindness, seizure, or paralysis). These symptoms often occur in close temporal relationship to stress or intense emotion. Conversion disorder is more common in young females, less-educated people, and those from lower socioeconomic classes. The image shows a Meckel diverticulum, the result of the persistence of a portion of the vitelline duct. The ileum is derived from the midgut, a portion of the primitive gut tube that gives rise to the intestinal tract from the distal duodenum to the proximal two-thirds of the transverse colon. Meckel diverticulum is characterized by the "rule of 2s": it is 2 inches long, 2 feet from the ileocecal valve, occurs in 2% of the population, presents in first 2 years of life, and may have 2 types of epithelium (gastric and pancreatic). Occasionally acid secreted from the gastric mucosa in a Meckel diverticulum may cause local ulceration and bleeding. These structures are proximal to the region that would be affected by a Meckel diverticulum. The mesonephric (Wolffian) duct gives rise to male internal reproductive organs: seminal vesicles, epididymis, ejaculatory duct, and ductus deferens. Neural crest cells give rise to many structures in the body, including the intestinal ganglia affected in Hirschsprung disease. However, this image shows a Meckel diverticulum, a midgut malformation that does not arise directly from neural crest cells. This patient presents with a pleural effusion, the accumulation of excess fluid in the pleural space. Pleural effusions can have a number of etiologies, including pneumonia, congestive heart failure, and cancer. Therapeutic thoracentesis can be performed to relieve symptoms and improve respiratory function. The intercostal vein, artery, and nerve run in the intercostal groove on the inferior surface of each rib. When thoracentesis is performed, the needle is always inserted at the most inferior aspect of an intercostal space to avoid these structures running along the superior aspect of the space. The parietal pleura is the outer layer of the pleura and is attached to the chest wall. When performing a therapeutic thoracentesis, it is necessary to pierce the parietal pleura in order to access the pleural space. The phrenic nerve is found deep in the thorax, running along the mediastinum and pericardium; it is too deep to be injured by thoracentesis. The pericardiophrenic vessels travel with the phrenic nerve along the mediastinum and pericardium. The tenth intercostal vessels and nerve run below the tenth rib, in the tenth intercostal space. The visceral pleura is the inner layer of pleura that covers the lungs and adjoining structures in the thorax. It is important to avoid piercing the visceral pleura because of its association with the lung. Avoidance of this structure, however, is not strongly dependent on inserting the needle at the inferior aspect of the intercostal space. The disease usually presents with marked leukocytosis and localized bacterial infections that are difficult to detect until they have progressed to an extensive, life-threatening level.
