Sinusitis evaluation

Many individuals, particularly those who partake in regular vigorous exercise, have heart rates less than 60 bpm. For those individuals, sinus bradycardia is normal and healthy, and does not require evaluation or treatment. However, some individuals develop symptomatic sinus node dysfunction. In the absence of correctable underlying causes, idiopathic sinus node dysfunction is referred to as sick sinus syndrome,12 and occurs with greater frequency with advancing age. The prevalence of sick sinus syndrome is approximately 1 in 600 individuals over the age of 65 years.12... 

Assess the patient s symptoms to determine if selftreatment is appropriate or evaluation by a physician is necessary. Determine type of symptoms, frequency (seasonal or chronic), and precipitating triggers. Does the patient have any AR-related complications (e.g., nasal polyposis, sinusitis, or otitis media) ... 

Although many clinical studies have been performed evaluating antibiotics for ABRS, no randomized, double-blind, placebo-controlled studies have used pre- and posttreatment sinus aspirate cultures as an outcome measure. Despite this, antibiotics appear to resolve symptoms more quickly and reduce failure rates and complications compared with no treatment.35-37 Since diagnosis usually is based on clinical presentation and not sinus aspirate cultures, clinicians must attempt to differentiate ABRS from viral rhinosinusitis. Therefore, it is important to limit antibiotic use to cases where infection is unlikely to resolve without causing prolonged disease patients with mild to moderate symptoms that persist for 10 days or worsen over 5 to 7 days and patients with severe symptoms,31,34... 

Immunocompromised patients on fluconazole with progressive sinus or pulmonary disease by radiography should be evaluated for possible mold infection. 

After treatment with AV nodal blocking agents and a subsequent decrease in ventricular response, the patient should be evaluated for the possibility of restoring sinus rhythm if AF persists. 

Other important components of the initial evaluation include a medical evaluation including both a medical history and physical examination. This can identify medical consequences of substance abuse, such as liver impairment from chronic alcohol abuse or sinus complications from cocaine use, as well as reveal needle tracks from a variety of self-injection sites that might not be readily apparent to casual observation. 

Munro and colleagues evaluated 54 trials including those prior to 1965 (71). Two trials included were specifically for maxillary sinus carcinoma and nasopharyngeal carcinoma. Additionally, the Veteran s Laryngeal Cancer study with the end-point being organ preservation was also included. In this study, the overall benefit of adding chemotherapy was 6.5% (3.7% for induction, 12.1% for concomitant, adjuvant chemotherapy was not assessed). 

CRT is now recommended for patients with LVEF less than or equal to 35%, sinus rhythm, and NYHA functional class III or ambulatory class IV symptoms despite recommended, optimal medical therapy and who have cardiac dyssynchrony, which is currently defined as a QRS duration greater than 0.12 ms, unless contraindicated. To date, over 4,000 patients have been studied in randomized clinical trials of CRT. A recent evaluation of complications from those studies suggest a risk of implant mortality of 0.4%, failure to implant a functioning LV lead in 10%, lead malfunction or dislodgement in 8.5%, and pacemaker infection in 1.4% [123].

Blood samples can be collected from the retro-orbital sinus or sublingual vein under light isoflurane anesthesia. The animals are not fasted prior to sampling. A minimum of three females per time-point and typically five time-points are necessary in order to evaluate the toxicokinetic profile. 

An increased incidence of cancer of the paranasal sinuses was observed in workers at factories where isopropanol was manufactured by the strong-acid process. The risk for laryngeal cancer may also have been elevated in these workers. It is unclear whether the cancer risk was due to the presence of diisopropyl sulfate, which is an intermediate in the process, to isopropyl oils, which are formed as by-products, or to other factors, such as sulfuric acid. Epidemiological data concerning the manufacture of isopropanol by the weak-acid process are insufficient for an evaluation of carcinogenicity (lARC, 1987). 

Intravenous amiodarone has been reported to be effective, converting 60% to 70% of patients to sinus rhythm in some trials (65-67). The efficacy has been evaluated in studies with different durations of AF... 

Fig. 18.11. 3D PC MR venography. There is only minimal flow in the area of the left transverse sinus. As these images do not give any anatomical information the evaluation must include images (CT or MRI) which provide the information whether this dural sinus is present and occluded or whether it is hypo-/aplastic...

CT venography of cerebral veins is a very reliable technique for the demonstration of intraluminal abnormalities of dural sinuses (Figs. 18.10a, 18.12a Ozsvath et al. 1997). In particular, multisection CT venography with subtraction of bone is a promising and competitive technique for the evaluation of veno-occlusive disorders of the cerebral veins and sinuses (Majoie et al. 2004). One disadvantage, however, is the radiation exposure. Conventional DSA is typically not needed unless endovascular treatment is necessary, since MRI, MRA and CT are usually sufficient to make a correct diagnosis. 

The cardiac effects of intracoronary infusion of cocaine have been studied in dogs and humans (42). The procedure can be performed safely and does not alter coronary arterial blood flow. The effects of direct intracoronary infusion of cocaine on left ventricle systolic and diastolic performance have been studied in 20 patients referred for cardiac catheterization for evaluation of chest pain. They were given saline or cocaine hydrochloride (1 mg/minute) in 15-minute intracoronary infusions, and cardiac measurements were made during the final 2-3 minutes of each infusion. The blood cocaine concentration obtained from the coronary sinus was 3.0 pg/ml, which is similar in magnitude to the blood-cocaine concentration reported in abusers who die of cocaine intoxication. Minimal systemic effects were produced. The overall results were that cocaine caused measurable deterioration of left ventricular systolic and diastolic performance. 

The causes of syncope in patients with Alzheimer s disease treated with donepezil have been reported in 16 consecutive patients (12 women, 4 men) with Alzheimer s disease, mean age 80 years, who underwent staged evaluation, ranging from physical examination to electrophy-siological testing (54). The mean dose of donepezil was 7.8 mg/day and the mean duration of donepezil treatment at the time of syncope was 12 months. Among the causes of syncope, carotid sinus syndrome (n = 3), complete atrioventricular block (n = 2), sinus node dysfunction (n = 2), and paroxysmal atrial fibrillation (n = 1) were diagnosed. No cause of syncope was found in six patients. Non-invasive evaluation is recommended before withdrawing cholinesterase inhibitors in patients with Alzheimer s disease and unexplained syncope. 

Why did Ms. J think a psychiatric evaluation for Mr. K was so important after meeting him only once First, Ms. J saw that his symptoms could be indicative of at least a couple of different disorders. As for Mr. K s sinus complaints, she was having trouble distinguishing between an obsessional thought and a delusion. In addition to wanting more information from Mr. K himself, she also wanted the opinion of another mental health professional. Second, Ms. J knew that OCD can be very difficult to treat without medication. She knew that for Mr. K to experience optimal relief from his symptoms, medication should at least be considered as part of the treatment plan.
