Episodic problems

Pig trials were conducted at the Kingsville Swine Unit of Texas A M University in the USA. The unit is a farrow-to-finish operation and has been in production for approximately 25 years. This facility has experienced episodic problems with post-weaning scours, which on occasion has resulted in relatively high morbidity and mortality rates. 

Treatment of Manic—Depressive Illness. Siace the 1960s, lithium carbonate [10377-37-4] and other lithium salts have represented the standard treatment of mild-to-moderate manic-depressive disorders (175). It is effective ia about 60—80% of all acute manic episodes within one to three weeks of adrninistration. Lithium ions can reduce the frequency of manic or depressive episodes ia bipolar patients providing a mood-stabilising effect. Patients ate maintained on low, stabilising doses of lithium salts indefinitely as a prophylaxis. However, the therapeutic iadex is low, thus requiring monitoring of semm concentration. Adverse effects iaclude tremor, diarrhea, problems with eyes (adaptation to darkness), hypothyroidism, and cardiac problems (bradycardia—tachycardia syndrome). 

Clinical studies with Norplant attest to its high contraceptive efficacy and safety. The main reason patients request the removal of Norplant is unpredictable vaginal bleeding episodes followed by amenorrhea. The bleeding problem is an unavoidable sequela of progestogen-only contraception. 

As indicated above, national policies and international conventions have been invoked to curb known, and usually obvious, sources of marine pollution. National legislation is used to control coastal discharges of contaminants. A major problem remains owing to the inadequate treatment of sewage prior to emission from land-based sources. The most important deleterious effects in this case are with respect to microbial water quality. This can have a direct influence on bathing criteria and result in beach closures during contamination episodes. An additional problem from land-based sources pertains to transboundary effects, whereby pollution may inadvertently be exported from one country to another. 

During the 30 years prior to the episode, fogs lasting for more than 3 days had occurred only five times, always in the winter, in 1901, 1911, 1917, 1919, and 1930. Some respiratory problems were also noted in 1911. Industrial activity was at a low level in 1917 and 1919. 

Before giving a nonnarcotic analgesic to a patient, the nurse assesses the type, onset, and location of the pain. It is important to determine if this problem is different in any way from previous episodes of pain or discomfort. If the patient is receiving a nonnarcotic analgesic for an arthritic or musculoskeletal disorder or soft tissue inflammation, the nurse should examine the joints or areas involved. The appearance of the skin over the joint or affected area or any limitation of motion is documented. The nurse evaluates the patient s ability to carry out activities of daily living. This important information is used to develop a care plan, as well as to evaluate the response to drug therapy. 

Ms. Martin has been prescribed propranolol (Inderal) for hypertension. She arrives at the outpatient dinic and tellsyou that she is having episodes of dizziness and at times feels as if she is going to faint. Discuss how you would investigate this problem and what information you could give Ms. Martin that might help her. 

Some patients with parkinsonism communicate poorly and do not tell the primary health care provider or nurse that problems are occurring. The nurse observes the patient with parkinsonism for outward changes that may indicate one or more adverse reactions. For example a sudden change in the facial expression or changes in posture may indicate abdominal pain or discomfort, which may be caused by urinary retention, paralytic ileus, or constipation. Sudden changes in behavior may indicate hallucinations, depression, or other psychotic episodes. 

Stored in reservoirs, and a growing social perception of problems related to water quantity and quality in reservoirs is expected. Just as an example, the recurrent drought episodes suffered by the Barcelona metropolitan area (Spain) in recent years placed reservoirs at the center-stage since then people are regularly informed about water resources stored in nearby reservoirs in newspapers and TV, and an iconic view from a reservoir has become a nonofficial monitor of the water supply volume available for the city (Fig. 1). 

While epinephrine is usually well tolerated in young and healthy individuals, there may be problems in elderly patients with cardiac arrhythmia or previous myocardial infarction episodes [31-33]. Pharmacological effects of epinephrine include rapid rise in blood pressure, pallor, anxiety, tachycardia, headache and tremor as well as vertigo. Most commonly these effects occur after intravenous injection or after overdosing epinephrine. Cardiac arrhythmia or pulmonary edema may develop in serious cases [33, 34]. 

Clearly, however, the flow simplification would be invalid on a small site with episodic projects, or in contexts with significant downtime due to changeover and setup activities for project-specific assays. Such simulation problems covering multiple projects and multiple assays, with use of a mix of shared and dedicated resources, can rapidly become intractable, and an early, com-monsense selection of the focus area for simulation is essential. 

The combustion products from sulfur Impurities In coal are particularly damaging to the environment. In humans, prolonged exposure to sulfur dioxide diminishes lung capacity and aggravates respiratory problems such as asthma, bronchitis, and emphysema. Concentrations as low as 0.15 ppm can incapacitate persons with these diseases, and at about 5 ppm everyone experiences breathing difficulties. In 1952 a particularly serious episode of SO2 pollution In London caused approximately 4000 deaths over several days. 

The PCP abuser poses unique problems for law enforcement agencies and the judicial system. McCarron et al. (1981), in reviewing medical and behavioral characteristics of 1,000 PCP episodes observed in medical emergency rooms, have noted the extremely high incidence (35 percent) of violence and rage reactions. Possibly...
