The last part of the 19th century was a period of great achievements in medicine and endocrinology. The thyroid gland evolved from being considered a rudimentary structure to an organ related to specific diseases. The singular importance of iodine became acknowledged. Graves-Basedow’s disease was described. Surgical treatment evolved with extraordinary speed. Theodor Kocher observed that the clinical picture in patients after total thyroidectomy was similar to the one seen in cretinism. In 1850, the first case of hypothyroidism or myxedema was described. Less than 50 years later, effective treatment was introduced. Another 50 years later, autoimmune thyroiditis was ascertained as the most frequent cause of hypothyroidism (in areas with no iodine deficiency). This paper gives a short...

...surgical patients are infections at the surgical site (Kalb, Lefevre, Dididze, & Levi, 2013). For reductions of infections on any surgical site, this skin will need to be cleaned (or prepped) and covered with a sterile towel or drape. The site of the incision is prepped so that bacteria or microbes that cause the infection are found on the skin surface. Due to these microbes, prepping a patient’s skin will be the most important step prior to any surgery. Different hospitals throughout the United States use many different products for the cleaning or prepping stage. At the hospital of my place of employment, there are three different agents that can be used. This list includes Chlorhexidine gluconate, chlorhexidine alcohol, and povidone iodine. Any type of infection involving the incision site can cause complications that could be long term for any patient to deal with and may have financial consequences to any hospital. This particular hospital is considering a change to standardize the prepping solution and needs to determine the cost factor if it were to change to a new product or to add premixed applicators of particular type of surgical prep solution. At this hospital, the current standard is using a surgical prep cleanse that the primary surgeon chooses to use. The hospital’s policy has no set standard for a particular prep solution being used. The CDC, in 1999, listed guidelines for prevention of infections at the incision site, including the use of an antiseptic cleanser...

...Respiratory Tract Infection which can seed Bacteria to surgical wounds (Ollivere et al., 2009). Prophylactic Antibiotics given prior to elective surgery remains debatable and of questionable value considering the risk of side effects, emergence of Multi-drug resistant Pathogens and Anaphylaxis, and therefore should be used according to guidelines like in patients with higher risk for developing SSI (Wright et al., 2008, Dixon et al., 2006). Also, procedures at certain body sites and those involving surgical reconstruction are better covered with prophylactic Antimicrobial agent (Rosengren and Dixon, 2010). Use of antiseptic scrub has been shown to reduce the incidence of SSI. Studies suggest that Chlorhexidine is superior to Povidone Iodine solutions in reducing Bacterial Colonization and SSI in postoperative patients (Paocharoen et al., 2009, Mimoz, 2010 and, Lee et al., 2010). Also, the use of Chlorhexidine Gluconate shower or bath for cleansing the skin by patients prior to dermatologic surgical procedures reduces the risk...

...Carbon from Latin: carbo "coal" is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity. There are several allotropes of carbon of which the best known are graphite, diamond, and amorphous carbon. The physical properties of carbon vary widely with the allotropic form. For example, diamond is highly transparent, while graphite is opaque and black. Diamond is among the hardest materials known, while graphite is soft enough to form a streak on paper (hence its name, from the Greek word "to write"). Diamond has a very low electrical conductivity, while graphite is a very good conductor. Under normal conditions, diamond has the highest thermal conductivity of all known materials. All carbon allotropes are solids under normal conditions with graphite being the most thermodynamically stable form. They are chemically resistant and require high temperature to react even with oxygen. The most common oxidation state of carbon in inorganic compounds is +4, while +2 is found in carbon monoxide and other transition metal carbonyl complexes. The largest sources of inorganic carbon are limestones, dolomites and carbon dioxide, but significant quantities occur in organic deposits of coal, peat, oil...

The best staining techniques to use is the Gram stain or the Acid- fast stain due to the fact that they both will provide a lot of information in detail regarding the bacteria being studied. It is very important to be observant of how each bacterium obtained reacts to each stain, and how the results obtained will lead us in a developing diagnosis. The first technique being used is the Gram stain. Gram stain is probably one of the most common used staining procedures used in the field of microbiology. It is one of the differential stains that are used to characterize bacteria in one of the two groups: either gram positive or gram negative bacteria. Bacteria prepared for the Gram stain is a heated fixed smear that is covered with a crystal violet. Because the purple stain impart its color to all cells. After a short period of time, the purple dye is then washed off, and the smear is then covered with iodine, a mordant. When the iodine is then washed off, both the gram-positive and gram-negative bacteria appear dark violet in color or purple. The next, process is the slide is then washed with alcohol...

...12.097 Environmental Chemistry of Boston Harbor – IAP 2006 Lab 1: DETERMINATION OF DISSOLVED OXYGEN BY WINKLER TITRATION 1. Background Knowledge of the dissolved oxygen (O2) concentration in seawater is often necessary in environmental and marine science. It may be used by physical oceanographers to study water masses in the ocean. It provides the marine biologist with a means of measuring primary production - particularly in laboratory cultures. For the marine chemist, it provides a measure of the redox potential of the water column. The concentration of dissolved oxygen can be readily, and accurately, measured by the method originally developed by Winkler in 1888 (Ber. Deutsch Chem. Gos., 21, 2843). Dissolved oxygen can also be determined with precision using oxygen sensitive electrodes; such electrodes require frequent standardization with waters containing known concentrations of oxygen. They are particularly useful in polluted waters where oxygen concentrations may be quite high. In addition, their sensitivity can be exploited in environments with rapidly-changing oxygen concentrations. However, electrodes are less reliable when oxygen concentrations are very low. For these reasons, the Winkler titration is often employed for accurate determination of oxygen concentrations in aqueous samples. 2. Scope and field of application This procedure describes a method for the determination of dissolved oxygen in aqueous samples, expressed as mL O2 (L water)...

...sanitation issues lead to contamination of water, which then leads to outbreaks of diseases. The documentary states that cholera outbreaks are very common in this area of Kenya because of people drinking contaminated water. Besides, chorea, the documentary also mentions that 1.5 million of the people here are also affected by AIDS, which is affected by contaminated water. To get this water, people, often mothers or girls, spend two to three hours round trip just to get one bucket. Luckily, there is a non-profit organization located here in Kenya called Water is Life, which is dedicated to helping developing countries with access to clean water. Water is Life also provided the people with straws that can filter water. The straws contain iodine crystals, charcoal, and a membrane that together can purify the water, making it safe to drink. These straws are very portable and make clean water more accessible. Another program in Kenya, Cooperative for Assistance and Relief Everywhere (CARE), was distributing PUR packets. These PUR packets used a chlorine compound to disinfect the water. Each packet is capable of purifying 10 liters of water. After mixing, the contaminants will settle out of the solution to the bottom, where it can be filtered out. After leaving Kenya, the girls went to the Dominican Republic, where they found another program called Filter Pure. This program started in 2006, purified water by using ceramic pots and sawdust. The iron in the ceramic and the carbon...
