Anisakiasis: Anisakiasis is caused by infection with seafood containing larvae of Anisakis, Contracaecum or Pseudoterranova spp. Prevention is dependent upon informing communities of the hazards of eating raw or inadequately prepared salt-water fish; and early evisceration of fish after capture and freezing of seafood at -20C for at least 60 h before sale. Cutaneous Larva Migrans: Cutaneous larva migrans (creeping eruption) is caused by infection with larvae of animal hookworms, usually Ancylostoma braziliense and A. Dracunculiasis: Dracunculiasis (dracontiasis, guinea-worm infection) is caused by infection with Dracunculus medinensis, acquired through drinking water containing larvae that develop in small freshwater crustaceans. It also weakens the anchorage of the worms in the subcutaneous tissues and they can then be removed by traction. However, since it has no effect on the larvae of pre-emergent worms, it does not immediately prevent transmission. Trichinellosis: Trichinellosis (trichinosis) is caused by infection with the larvae of Trichinella spiralis. Each case of confirmed or even suspected trichinellosis infection should be treated in order to prevent the continued production of larvae. In both adults and children, mebendazole (200 mg daily for 5 days), albendazole (400 mg daily for 3 days) and pyrantel (10 mg/kg daily for 5 days) are all effective. Prednisolone (40-60 mg daily) may be needed to alleviate the allergic and inflammatory symptoms. Visceral Larva Migrans: Visceral larva migrans (toxocariasis) is caused by infection with the larval forms of Toxocara canis and less commonly, T. A 3 week oral course of diethylcarbamazine kills the larvae and arrests the disease, but established lesions are irreversible. To reduce the intensity of allergic reactions induced by dying larvae, dosage is commonly commenced at 1 mg/kg twice daily and raised progressively to 3 mg/kg twice daily (adults and children). Ocular larva migrans occurs when larvae invade the eye, causing a granuloma which may result in blindness. In order to suppress allergic inflammatory responses in patients with ophthalmic lesions, prednisolone should be administered concurrently, either topically or systemically.

It may be a self-limiting localized skin lesion but may range from this to disseminated progressive disease.

Later in the decade the theory was widely accepted and soon pink disease was no longer part of the usual pediatric out-patient clinic. The effects on humans of mercury-containing medicinals and home remedies used to be studied quite regularly by medical researchers (Warkany and Hubbard, 1953); but since, aside from vaccinal thimerosal, such products have declined dramatically in number since the 1950s and 1960s, most mercury researchers today focus on biochemical studies or environmental sources like fish and coal plants. Likewise, it is not surprising that neither mercury experts nor autism professionals have ever investigated autism as a possible disease of mercury exposure. Since its discovery by Kanner, autism has been characterized in almost exclusively psychological terms. The descriptions have been such that the symptoms would be essentially unrecognizable as manifestations of poisoning to any mercury expert not looking closely. A perfect example is Kanner himself, who recorded feeding problems and vomiting in infants and concluded: "Our patients, anxious to keep the outside world away, indicated this by the refusal of food. In 1987, Robert Sternberg would propose a "unified theoretical perspective on autism" by defining the disorder in terms of a "triarchic theory of intelligence," and in the same publication Lorna Wing and Anthony Attwood would write: "Sometimes young autistic children will stand in a dejected posture, with tears streaming down their faces, as if they suddenly felt their helplessness in the face of a world they cannot understand. Thus biomedical research in autism existed, but it was mostly relegated to the margins as psychology held center stage, and the symptomatic characteristics of autism continued to be presented in accord with psychological biases. Congressional mandate led to the public quantification of the cumulative amount of mercury in vaccines, raising interest in understanding its effects. With parents already suspecting a vaccine-autism link, the environment was right for investigations focused on the link between vaccinal mercury and autism. Such research might focus on the following areas, with others undoubtedly still to be identified: (a) Chelation methods which will work across all body tissues and especially the brain. Other promising but less studied chelators like alpha lipoic acid can cross the bbb (Fuchs et al, 1997) and should be studied in autism. The work of Hu and colleagues suggests that Hg can cause an immune reaction in any individual, but some are protected by a counteractive immunosuppressive response, and Warkany and Hubbard have pointed out that individuals who are Hg-sensitive can later become "immune". It may be possible to engineer these responses in autistic individuals through careful research. Except for trace amounts, vaccines without thimerosal are currently available for all routinely recommended immunizations for children under 6 years (Institute for Vaccine Safety, 1999). Thus, any issues being raised here are related to how vaccine programs are run, not with vaccines themselves. As Altman and Bland have aptly demonstrated (1995), "absence of evidence is not evidence of absence. Current practice is to track adverse reactions only if they occur within one month of the vaccination. The experience with mercury clearly shows that an adverse event may not manifest for months if not years. Studies on adverse reactions must involve long term tracking of patients; they should investigate the impact of multiple injections as well as compare reactions to vaccines with and without various additives; and sample sizes need to be large enough to include especially sensitive groups.

Foreword It has been a great privilege to be involved in the production of this innovative undergraduate textbook in psychiatry. When one of the students attached to my clinical firm first suggested the concept of a series of specialist textbooks written by students, for students, my reaction was a mixture of curiosity and scepticism. Together with Amir Sam, the authors of this book are among the very best students of psychiatry I have ever had the pleasure to teach. In the process of editing this book, I have learned a huge amount about teaching psychiatry, especially about the way that psychiatry as a subject is perceived by students. It pays particular attention to explaining those topics which students find especially difficult, without losing the emphasis on those conditions which clinicians consider to be important.

Our peerless basic and translational science faculty are both immensely creative and highly productive. Sewall Professor in Otorhinolaryngology and Professor, by courtesy, of Neurosurgery and of Surgery Stanford Otolaryngology ­ Head & Neck Surgery Ranked in the top 3% achieving national recognition Stanford University Ranked in top 2 of U. Our clinical services focus on high-quality tertiary care of complex diseases in the head and neck region. Our patients come from a wide geographic area to benefit from our specialized expertise, leading surgical outcomes, and cutting-edge technology. Our research group, which is a mixture of basic scientists and surgeon-scientists, enjoys numerous collaborations throughout Stanford bioscience and technology. As you will see in this booklet, our research scope spans a wide variety of topics including head and neck cancer, sinonasal disease, voice disorders, obstructive sleep apnea, health care delivery innovations, and many other specialty topics. A major thrust of our research is to overcome hearing loss through regenerative means. To achieve this goal we have created the Stanford Initiative to Cure Hearing Loss, which is a long-term, goal-oriented, multidisciplinary research effort. A number of our surgical faculty, in collaboration with Stanford Biodesign and Stanford Engineering, have a special interest in medical device innovation. Together, we have more than 50 current research grants and our faculty publish more than 200 scholarly contributions annually. We are honored that our departmental faculty include many leaders in Stanford Medicine including our Dean (Lloyd Minor), the Chief of the Stanford Health Care Medical Staff (Edward Damrose), and the Medical Director of the Stanford Cancer Center (Eben Rosenthal). Our advances-particularly in ultrasound-assisted diagnostic procedures, surgery, and nonsurgical treatments-are unparalleled. She is a pioneering researcher and practitioner in the applications of ultrasound in thyroid and parathyroid care. Her renowned work has helped bring us to the cusp of a new era of incorporating ultrasound into the practice of head and neck surgery. More surgeons now recognize its value in the examination and treatment of tumors and diseases of the salivary gland; examination of the tongue and airway in sleep surgery; tattooing, as an alternative to wire localization, to guide precise surgery; and a myriad of other applications. Ultrasound is especially valuable in pediatric cases, since it is non-invasive, uses no radiation, requires no sedation, and can be performed in the office.

In some cases, we reconstruct a head and neck defect using tissue within the head and neck. However, in situations where the defects are too large or require special components, such as bone, our reconstructive surgeons look to tissue in different body sites and perform microvascular reconstruction. In microvascular reconstructive surgery, we move a composite piece of tissue from another part of the body to the head and neck. The tissue most commonly comes from the arms, legs, or back, and can include bone, skin, fat, and/or muscle. Transfer of the tissue to the head and neck allows us to rebuild a jaw, optimize tongue function, or reconstruct the throat. When pieces of tissue are moved, they require their own blood supply for survival in their new location. After the reconstruction is secure in the head and neck, we reconnect the blood vessels that feed the tissue transplant to new blood vessels in the neck. Since these blood vessels are usually 1 to 3 millimeters in diameter, the connections must be done under microscope. We also combine this type of reconstruction with other advanced surgical techniques, such as computer modeling, 3D printing, and customized implant fabrication.

If possible they can also be reassigned during the incubation period to areas where the patients are not as susceptible or non-patient care areas. Neonates may not be protected given that they are frequently open for nursing purposes. If not,they should receive post exposure vaccination as soon as possible unless contraindications exist such as pregnancy.
