Describe factors affecting the use of primary, implications of using primary antitubercular secondary, and other drugs in the treatment of drugs. Critical Thinking Scenario John Phillips, a homeless person with a history of drug and alcohol abuse, comes to the emergency depart- ment with a productive cough, complaints of night sweats, and fatigue. The physician suspects tuberculosis (TB) and orders a purified protein derivative (PPD) skin test, chest x-ray, and sputum for acid-fast bacilli. Reflect on: the necessary infection control measures to use before TB is confirmed or ruled out. Factors that affect compliance with drug treatment for John Phillips and a plan to improve and monitor compliance. Phillips will require drug treatment, and how you can evaluate when the TB is cured. OVERVIEW Tuberculosis commonly occurs in many parts of the world and causes many deaths annually. In the United Tuberculosis (TB) is an infectious disease that usually affects States, active disease has waned to a historical low level. It is caused by Mycobac- include increased exposure during a resurgence of active terium tuberculosis, the tubercle bacillus.

They also restrain extremes of motion in Discal degeneration is generally considered as the pri- all planes. All spinal ligaments have a high content of col- mary source of pure low-back pain. Ligamentum flavum, which connects the adjacent fibers identified in the inner annulus and nucleus can be vertebrae, has a high percentage of elastin, allowing con- sensitized by the cytokines and neuropeptides present in traction during flexion and elongation during extension the degenerated disc [8, 18, 20]. As part of the aging process, ligaments undergo of nociception can be found in the spinal unit, including chemical and macroscopic changes, including a rise in the muscles, ligaments, and facets. Nociception coming from concentration of elastin, which decreases tensile proper- these various tissues is difficult to distinguish from disco- ties, resulting in ligamentous weakening affecting the sta- genic pain. Moreover, recognition of the painful disc in bilizing function of the longitudinal ligaments [13]. Therefore, the dition, aging and degeneration of the ligamentum flavum exact source of the pain is difficult to identify and often leads to increased thickness and bulging, often disclosed remains unknown at the individual level [4]. Radicular pain is the other pos- lizes and modifies the load in static and dynamic situa- sible expression of the degenerative spine.

From the Treatment of Enuresis with Self-devised Ma Chang Long Mu Tang (Ephedra, Acorus, Dragon Bone & Oyster Shell Decoction) by Meng Xiang-min et al. Twenty-six cases presented a particular pattern of night- time enuresis and 14 cases did not. Treatment method: Ma Chang Long Mu Tang (Ephedra, Acorus, Dragon Bone & Oyster Shell Decoction) was composed of: Ma Huang (Herba Ephedrae), 5-10g Shi Chang Pu (Rhizoma Acori Tatarinowii), 10-20g calcined Long Gu (Os Draconis), 15-25g Mu Li (Concha Ostreae), 15-25g If there was kidney qi vacuity as evidenced by enuresis many times per night, cold limbs, aversion to cold, a pale tongue, and deep, forceless pulse, 15-25 grams of Shan Zhu Yu (Fructus Corni) and 20-30 grams of Huang Qi (Radix Astragali) were added. If there was liver channel damp heat as evidenced by scanty, yel- lowish urine, a bitter taste in the mouth, a red tongue with yellow fur, and a rapid pulse, 15-25 grams of Long Dan Cao (Radix Gentianae) and 10-20 grams each of Sheng Di (uncooked Radix Rehmanniae) and Mu Tong (Caulis Akebiae) were added. One packet of these medicinals was decocted in water until 200 milli- liters of medicinal liquid remained. This resulting liquid was taken in 50 milliliter doses after lunch and dinner. If the disease was not cured in one course, treatment was continued for another course. Study outcomes: Thirty-four cases were cured, four improved, and two got no 64 Treating Pediatric Bed-wetting with Acupuncture & Chinese Medicine improvement. Fourteen of these cases were cured and one case improved after just one course of treatment. From the Empirical Treatment of 36 Cases of Enuresis Mainly by Using Self-devised He Che Gu Quan San (Placenta Secure the Stream Powder) by Yang Dong-shan & Cao Sheng- you, Gan Su Zhong Yi (Gansu Chinese Medicine), 2000, #1, p. The shortest course of disease was one year, and the longest was 20 years. All these patients had enuresis 1-2 times per night, and eight cases also had enuresis during their daytime nap. The TCM pattern presented by these patients was central qi vacuity in 18 cases, yang vacuity in 11 cases, damp heat in five cases, and blood stasis in two cases. Treatment method: He Che Gu Quan San (Placenta Secure the Stream Powder) was composed of: Zi He Che (Placenta Hominis) 1 (after washing the placenta and allowed to dry) Niu Yin Jing (bull penis) 1 Huang Qi (Radix Astragali), 50g Yi Zhi Ren (Fructus Alpiniae Oxyphyllae), 30g scorched Du Zhong (Cortex Eucommiae), 30g Shu Di (cooked Radix Rehmanniae), 30g Sang Piao Xiao (Ootheca Mantidis), 30g Shan Zhu Yu (Fructus Corni), 30g Gou Qi Zi (Fructus Lycii), 30g stir-fried Bai Zhu (Rhizoma Atractylodis Macrocephalae), 30g Fu Ling (Poria), 20g Sha Ren (Fructus Amomi), 20g If there was shortness of breath, disinclination to talk, lack of strength in the four limbs, a pale tongue, and a weak pulse, 30 Chinese Research on the Treatment of Pediatric Enuresis 65 grams of Ren Shen (Radix Ginseng) and 20 grams of Sheng Ma (Rhizoma Cimicifugae) were added. If there was lumber pain, a bitter taste in the mouth, a red tongue with slimy, yellow fur, and a slippery pulse, 30 grams each of Long Dan Cao (Radix Gentianae) and Yi Yi Ren (Semen Coicis) were added. If there was a dark facial complexion, dark, blue-green tongue body with static spots on the side, and a choppy or rough pulse, 30 grams each of Tao Ren (Semen Persicae) and Di Long (Pheretima) were added. These medicinals were all ground into a fine powder and placed in a glass bottle for storage. Children under 12 years of age took 6- 10 grams of this powder, two times per day mixed in 80-100 milli- liters of hot water and taken warm. One dose was given before breakfast and another was given before dinner. During treatment, the patients were asked to avoid fatty, greasy, sweet, or spicy food, alcohol, and cigarettes. From the Treatment of 78 Cases of Pediatric Enuresis by the Method of Regulating Both the Lungs & Kidneys by Li Xiang Dong, He Bei Zhong Yi (Hebei Chinese Medicine), 2003, #4, p. The course of disease was as short as two months and as long as 11 years.
