Study Intervention: Patients were randomized to receive either: (1) placebo twice daily; (2) aspirin 25 mg twice daily; (3) modifed-release dipyridamole 200 mg twice daily; or (4) aspirin 25 mg and extended-release dipyridamole 200 mg twice daily blood pressure medication makes me dizzy order discount vasodilan on-line. Criticisms and Limitations: • T ere was no strategy in place to deal with patients who developed headache blood pressure up buy discount vasodilan 20 mg. However blood pressure cuff vasodilan 20 mg purchase on-line, this dose was employed because the investigators wanted a low dose of aspirin given the results of previous trials5,6 and 81 mg aspirin was not available in europe. Her extended cardiac monitoring revealed no evidence of paroxysmal atrial fbril- lation. She has no clinical history of heart failure and no history of hemorrhage or bleeding diathesis. She takes an angiotensin-converting enzyme inhibitor, a statin, thrice daily insulin, and topiramate for her headaches. Her exam is notable for mild hemiparesis of her right leg and she walks with a cane. An MrI of her brain reveals chronic microvascular disease and confrms her prior stroke. T is patient has a clear indication for an antiplatelet agent such as aspirin or dipyridamole and no compelling indication for anticoagulation. Moreover, if the dipyrid- amole were combined with aspirin in a single capsule (as is commonly done) and she stopped taking the combination medication due to her headaches, she would risk being completely without antiplatelet therapy. Aspirin and extended-release dipyridamole versus clopidogrel for recurrent stroke. Who Was Excluded: Patients with atrial fbrillation, cardioembolic stroke, or subarachnoid hemorrhage. Also excluded were patients who were not ambula- tory, had a modifed rankin Score >3 or lDl <100mg/dl. Study Intervention: eligible patients were randomly assigned to receive 80 mg atorvastatin per day or placebo. Follow-up visits were scheduled 1, 3, and 6 months afer enrollment and every 6 months thereafer. By 1 month into the trial, lDl in the atorvastatin group had fallen by 53% compared with no change in the placebo group (P < 0. Criticisms and Limitations: • T e investigators did not gather data on the level of disability arising from strokes in the respective groups. T is information is important as the most important efect of stroke on a population is the increased burden of disability as opposed to mortality. T is trial specifcally dealt with patients without atrial fbrillation and without a history of coronary artery disease. T ey found that patients already taking a statin who have an acute ischemic stroke have a lower poststroke mortality (at 90 days) and a reduced risk of deterioration during their hospitalization. T ere was an associated reduction in the lDl and total cholesterol levels in the treatment group versus the placebo group. He has no residual def- cits from his stroke and is independent in all his basic and instrumental activ- ities of daily living. What are the benefcial efects for this man of using statin therapy as a lipid- lowering agent? Atorvastatin was also associated with a 16% reduced risk of further ischemic stroke at the cost of a slightly elevated risk of hemorrhagic stroke. It would therefore be reasonable to recommend it to this gentleman as part of ongoing secondary prevention of further cerebrovascular events. Who Was Excluded: Patients with prosthetic heart valves, mitral stenosis, or other conditions such as recent pulmonary embolism that required anticoagu- lation, or contraindications to aspirin or warfarin. Patients with atrial brillation documented within 6 months of the trial Randomized Low-intensity, xed-dose Adjusted-dose warfarin warfarin plus aspirin Figure 47. A 1-year fol- low up period may not have been sufcient, and long-term safety could not be assessed. T e comparison of adjusted-dose warfarin was to a combination of medications uncommonly used (low-intensity warfarin therapy in addition to aspirin). Since she has done well so far on warfarin, it might be advisable to continue with the current regimen; however, if she feels strongly that she does not want to continue the frequent monitoring, it would also be reasonable to discuss with her the risks and benefts of the newer anticoagulants that do not require regular anticoagulation testing.

The incidence of long-term mortality has ranged from 25% to 30% over 3- to 36-month of follow-up across various studies pulse pressure chart buy vasodilan 20 mg low price. Updated meta-analysis of septal alcohol ablation versus myectomy for hypertrophic cardiomyopathy hypertension treatment guidelines 2014 cheap 20 mg vasodilan visa. Transthoracic echocardiography is a reliable and versatile tool for the assessment of cardiac structure prehypertension spanish vasodilan 20 mg amex, function, and hemodynamics. Compared with other cardiovascular imaging modalities, it is relatively inexpensive, does not expose the patient to radiation, is noninvasive, displays live real-time images, and is widely available. Sound waves consist of mechanical vibrations that produce alternating compressions and rarefactions of the medium through which they travel. Ultrasound consists of sound waves in the frequency range that is higher than what is audible to humans (>20,000 Hz). All waves can be described by their frequency (f), wavelength (λ), velocity of propagation (v), and amplitude. Frequency is defined by the number of cycles occurring per second (cycles/second or Hz) and wavelength is measured in meters. Velocity, frequency, and wavelength are described by the following relationship: Velocity = frequency × wavelength or v = f × λ The typical adult echocardiographic examination uses a transducer with ultrasound frequency between 2. This has important implications because image resolution cannot be >1 to 2 wavelengths (e. In addition, the depth of penetration of the ultrasound wave is directly related to the wavelength, with shorter wavelengths penetrating a shorter distance. Therefore, higher frequency transducers result in the use of shorter wavelengths that improve image resolution but at the cost of reduced depth penetration. A piezoelectric substance has the property of changing its size and shape when an electric current is applied to it. An alternating electrical current will result in rapid expansions and compressions of the material and thus produce an ultrasound wave. The piezoelectric crystal also deforms in shape when an ultrasound wave strikes the material, resulting in the production of an electric current. The transducer, and the piezoelectric crystal, thus oscillates between a short burst of transmitting ultrasound waves, with a brief period of no ultrasound transmission when it awaits reception of the reflected signals. Tissue harmonic imaging has become the standard imaging technique in many laboratories. It utilizes the principle that as ultrasound waves propagate through tissue, the waveform becomes altered by the tissue, with the generation of new waveforms of higher frequency but which are multiples of the baseline fundamental frequency. Setting the transducer to receive only harmonic sound waves that are multiples of the fundamental frequency improves image quality significantly. This image quality improvement is based on the fact that weak signals, which tend to be artifacts, create almost no harmonics. In addition, shallow structures, such as the chest wall, generate weak harmonic signals, whereas at depths of 4 to 8 cm, where the heart is located, maximal harmonic frequencies develop. These phenomena result in fewer near-field artifacts and better endocardial definition. One limitation of harmonic imaging is that valve leaflets appear thicker—an artifact generated during image processing that appears to be related to the rapid motion of the leaflets. The steps involved in creating a final ultrasound image are transmission and reception of waves, conversion to electrical signals, filtering, and extensive computer processing. Patient and probe positioning, electrocardiographic lead placement, and transducer selection are the first steps to beginning the echocardiographic examination. For the parasternal and apical positions, the patient should be in the left lateral decubitus position, with the left arm extended behind the head, because this brings the heart into contact with the chest wall. The subcostal and suprasternal views require the patient to be in the supine position. It is important that irregular beats be identified and excluded from the analysis. In general, any Doppler index requires the average of at least three measurements. For patients with very high heart rates, or with a noisy electrocardiographic signal, the digital clips can be set to record for a predefined period of time (usually 2 seconds). Transducer frequency is important, because at higher frequencies, spatial resolution improves but at the expense of reduced depth penetration.

Next, lavage the entire field with 70% isopropyl alcohol to flush the remaining phenol from the tissue. The base of the “L” is an incision just through the dermis down to , but not into, the nail root. The base of the “L” becomes a skin flap, which is dissected free of the nail matrix and reflected. The next incision is parallel to the first incision beneath the skin flap and becomes semielliptical distally to join the first incision. The tissue sliver is dissected free of the periosteum and dissected proximally back onto the base of the phalanx until this portion of the 404 nail root is freed. When the Frost technique was first described, no sutures were advised because it was thought to compromise blood flow. Plastic Lip Involves excision of a pie-shaped wedge of tissue taken from the side of the toe. A second incision is made in the skin at the nail fold, completing an ellipse with the first incision. A wedge of tissue is then removed down to the periosteum, and the wound is curetted.

Anything that severely reduces the blood sugar (<40 mg/dL) hypertension renal disease buy vasodilan 20 mg cheap, such as exogenous insulin overdose blood pressure 8959 order vasodilan online now, islet cell adenoma blood pressure medication name brands discount vasodilan 20 mg buy online, Addison disease, and hypopituitarism, may cause a seizure. Table 19 Convulsions Irritability of the nerve cell is more often caused by electrolyte alterations. The same equation that applied to muscle applies here: Hypocalcemia may at first lead to tetany, simulating a convulsion. The causes of hypocalcemia include hypoparathyroidism, vitamin D deficiency, malabsorption syndrome, calcium-losing nephropathy, and chronic nephritis. Hypomagnesemia must be ruled out, especially in chronic alcoholics and in malabsorption syndromes. Moving from the physiologic causes of seizures to the anatomic analysis, the physician’s main consideration is that something mechanical is irritating the nerve cell. The nerve cell may be irritated by a tumor of the supporting tissue, an abscess, or a hematoma. Focal accumulation of fluid in the brain substance as in encephalitis, concussions, and increased intracranial pressure from whatever causes may lead to a seizure. A depressed skull fracture is occasionally the mechanical irritant, as is a scar from an old skull injury. Turning to exogenous factors, one must consider a host of chemicals and drugs that may cause seizures, most commonly alcohol, paint thinners, lidocaine (Xylocaine), phenothiazine drugs, and bromides. A bolus of almost any substance may occasionally cause seizures if it is large enough. In contrast, lupus erythematosus and other collagen diseases may frequently present with seizures. Approach to the Diagnosis The first thing to do is ascertain whether the motor disturbance or episode of loss of consciousness was really a seizure. Another way to rule out hysterical seizures is have a member of the family take a video of the patient during a seizure. Be sure to ask about previous head trauma (including birth trauma), anoxia, meningitis, or encephalitis. If the clinician is too busy or not equipped to do this, referral to a neurologist is done at this point. If there are focal neurologic signs or papilledema, there is a strong chance that the patient has a space-occupying lesion such as tumor, subdural hematoma, or abscess and will need a neurologist anyway. If there is fever, meningitis or encephalitis must be considered in the differential diagnosis. If there is a heart murmur or irregular heartbeat, cerebral 238 embolism should be suspected. Patients with possible multiple sclerosis need a spinal fluid analysis, and visual, somatosensory, or brainstem-evoked potential studies. Elderly patients should have a chest x-ray done to exclude a primary tumor of the lung. Therapeutic trial of anticonvulsants Case Presentation #12 A 56-year-old black male mechanic gave a 1-month history of daily generalized headaches (occasionally associated with nausea and vomiting) on awakening in the morning. Based on the method described above, what would be your list of possible causes at this point? Neurologic examination revealed hyperactive reflexes in the right lower extremity and a positive Babinski sign. The irritation may be intrinsic, in which case it is usually inflammatory, neoplastic, or toxic, or it may be extrinsic, in which case it is often neoplastic or vascular (Table 20). Intrinsic irritation: Pharyngitis, whether due to virus, Streptococcus, or diphtheria, is a common cause of cough. In the larynx, the numerous infections of the pharynx discussed above may irritate the cough centers but, in addition, laryngeal polyps, tuberculosis, and trauma from overuse are important causes. The more common causes of cough, especially a nonproductive cough, are in the tracheobronchial area. Numerous viruses cause tracheobronchitis, especially influenza, but bacterial causes such as whooping cough should always be considered. Tuberculosis and carcinoma are important here, as are toxic gases such as chlorine and cigarette smoke.

Incidence rate: It is calculated as follows: Number of new cases of a disease Incidence under studdy during a specified period of time = ×1000 Rate Total susceptible popuulation or population at risk of developing the disease unnder study during a specified period of time blood pressure 220 120 purchase vasodilan 20 mg on line. The odds ratio can also be defined (in terms of group wise odds) as the ratio of the odds of an event occurring in one group to the odds of it occurring in another group heart attack 3d purchase 20 mg vasodilan, or to a sample based estimate of that ratio These groups might be men and women blood pressure medication starting with n vasodilan 20 mg purchase overnight delivery, an experimental group and a control group, or any other dichotomous classification. If the probabilities of the event in each of the groups are p1 (first group) and p2 (second group), then the odds ratio is: p / 1 − / pq12 = p / 1 − / pq21 where qx=1–px. An odds ratio of 1 indicates that the condition or event under study is equally likely in both groups. An odds ratio greater than 1 indicates that the condition or event is more likely in the first group. Relative risk is a ratio of the probability of the event occurring in the exposed group versus a non-exposed group. So the attributable risk for lung cancer in smokers, in essence, simply the rate of lung cancer amongst smokers minus the rate of lung cancer amongst non-smokers. This is also frequently referred to as the “risk difference” when dealing with risk data or “rate difference” with rate or person-time data. According to standard 2 × 2 contingency table: • Risk among exposed – Risk among non-exposed • Risk of disease among exposed = [a/[a + b)] • Risk of disease among unexposed = [c/[c + d)] • Risk difference = [a/[a + b)] – [c/[c + d)] • For null hypothesis, risk difference will be equal to ‘zero’ iii. This measure is useful for determining the relative importance of exposures for the entire population and is the proportion by which the incidence rate of the outcome in the entire population would be reduced if exposures were eliminated. Prevalence rate in a cross-sectional study: Outcome variable/Effect: (Infant colic) Total Present Absent Predictor variable: Present a = 15 b = 167 a + b = 182 Cause: smoking among mother Absent c = 111 d = 2477 c + d = 2588 Total a + c = 126 b + d =2644 a + b + c + d = 2770 Prevalence of colic with smoking mothers = a/a+b = 15/182 = 8. It means that 90% of lung cancer can be eliminated if the factors under study could be controlled or eliminated. To provide scientific proof of etiological (or risk) factors which may permit the modification or control of those diseases. To provide a method of measuring the effectiveness and efficiency of health services for the prevention, control and treatment of disease and improve the health of the community. The researcher/investigator using an experimental design is an active agent rather than passive observer. In intervention studies, the researcher manipulates a situation and measures the effects of this manipulation. Usually (but not always) two groups are compared, one group in which the intervention takes place (e. The clinical trial is an example of an experimental study in which the investigator introduces some form of treatment. Other examples include animal studies or laboratory studies that are carried out under experimental conditions. Experimental studies provide most convincing evidence for any hypothesis, as it is generally possible to control the factors that may affect the outcome. The design which minimizes bias as well as experimental error (variation) and maximizes the reliability of the data collected and analyzed is considered a good design. The following three basic principles are applied to achieve the above goals while designing experimental studies. The principle of replication underlines the importance of repeating the experiment, or readings of the experiment more than once, in order to avoid/neutralize experimental errors and maximize the reliability of the data. It means that each treatment is applied in many experimental units, or each phenomenon should be studied in different locations/centers (multi-centered studies). The principle of randomization provides protection, when we conduct an observational study or experimental study, against the effects of extraneous factors and bias. Eliminating bias, which is mainly caused due to human beings involved in the study (observer bias, selection bias, information bias, assessment bias, recall bias, response bias, healthy entrant effect) is the basic aim of a research design. In other words, this principle of randomization indicates that we should design or plan the study/experiment in such a way that the variations caused by extraneous factors can all be combined under the general heading of “chance”. The principle of randomization is achieved through selecting the sample units of a study/experiment randomly. In observational studies, it is achieved by following probability-sampling techniques (simple random sampling stratified random sampling, systematic random sampling, multi- stage/phase random sampling, etc). In clinical trials, randomization is achieved through single/double blind trials, cross-over trials, etc. The principle of local control also helps us to eliminate the variability due to extraneous factors. It is often possible to group observational subjects/experimental units that share similar characteristics into a homogeneous block or stratum (e.

Vasodilan 20 mg on-line

Concomitant vitamin C (Answer C) may be benefcial to maintain stomach acidity blood pressure on apple watch vasodilan 20 mg order on line, but is not required blood pressure ranges too low discount vasodilan american express. Which of the following is the correct set of transfusion triggers used in the study and the main outcomes? Based on these results pulse pressure 24 vasodilan 20 mg purchase amex, the authors concluded that a “restrictive strategy is at least as effective as and possibly superior to a liberal transfusion strategy in 206 9. None of the other choices (Answers B, C, D, and E) represent the correct triggers and/or interpretation of the trial. A 62-year-old male presents to the emergency department with severe chest pain, and left-sided arm pain and numbness. He said the pain in his arm radiates up to his neck and he rates the pain a 6 out of 10. He has no signs or symptoms of bleeding and his vital signs are relatively stable. Disagree—Ask that she prepare and release the unit, as requested by the physician D. Agree—Transfusion is not indicated and the physician should receive a reprimand from the patient safety committee E. There are no planned invasive procedures and the patient has no bruising or petechiae. This order comes in when the blood bank is critically short on platelets with only 8 left on the shelf and no platelets coming for 24 h (your minimum inventory is usually 15 or more). Since this blood bank is part of a large tertiary care center that has a busy trauma, transplant, and high-risk obstetric program, the blood bank technologist calls to the foor and explains the situation, but the physician insists that his patient receive priority. Inform him that platelet counts >10,000/µL are safe in stable patients with no evidence of bleeding B. Give him the platelets and call another blood supplier to help with critical shortage E. Though a multitude of clinical scenarios exists, studies suggest that stable, non-bleeding patients, that are not pre or postoperative do not require platelet transfusions until the platelet count is lower than 10,000/µL. Answer: A—Platelet counts of >10,000/µL appear to be safe in stable nonbleeding patients; however, no studies demonstrate that platelet counts of <10,000/µL are safe (Answer E). Though you may call other blood suppliers to help with your critical shortage, it should not be done just to get this noncritical patient a unit of platelets that is not clinically necessary (Answer D). An example of platelet transfusion thresholds in the author’s facility is as follows but note that each hospital must decide on their own thresholds based on their unique patient population. Such activities could include establishing evidence-based transfusion thresholds, reviewing root cause analysis of adverse events, and reviewing forms related to transfusion (e. During a monthly audit of 50 transfusion orders, which of the following orders would warrant a letter to the physician from the medical director of the blood bank? An order for one unit of platelets to a stable, nonbleeding patient with a count of 37,000 /µL in preparation for an emergent coronary bypass procedure D. An order for one unit of apheresis platelets to a patient on aspirin with mild bleeding and a platelet count of 162,000 /µL Concept: A hospital’s transfusion policy must take into account many different clinical scenarios for each blood product in the inventory. Regulatory agencies require that a certain percentage of transfusion orders be reviewed on a monthly basis to ensure that transfusion thresholds are being adhered to for most patients. It is the responsibility of the medical director of the blood bank to oversee this process and decide when a letter should be sent to the physician that transfused outside the guidelines, to inform him/her of transfusions that were deemed clinically inappropriate during the audit. In turn, it is expected that the ordering physician will provide an explanation for the decision to transfuse the specifc patient. Answer: D—A stable, nonbleeding asymptomatic patient with iron defciency anemia should be treated with iron therapy, not transfusion. Sending out letters for transfusions close to the recommended triggers will likely lessen the overall effectiveness of the process. As mentioned earlier, many different clinical scenarios impact the decision to transfuse platelets. In these cases (Answers C and E), the decision to transfuse is appropriate given the patient’s upcoming surgery, and the patient’s recent use of an antiplatelet agent with clinical signs of bleeding. Although the beneft of platelet transfusion in bleeding patients who are on antiplatelet therapy is not conclusive, this action is not yet considered to be a major deviation from the standard of care by many experts. Overall, the changes affect the ability of the cells to carry and deliver oxygen, as well as to remain intact while traversing vessels of small caliber.

The use of temporary and permanent mechanical circulatory support is described in detail in Chapter 12 heart attack with pacemaker trusted vasodilan 20 mg. Patients with refractory cardiogenic shock and cardiogenic pulmonary edema may benefit from the temporary use of intra-aortic balloon counterpulsation or an alternative temporary means of mechanical circulatory support (i. Transition to chronic pharmacotherapy is implemented once clinical stability is achieved. If β-blockers were held due to cardiogenic shock, they can be cautiously reintroduced in stable, euvolemic patients. The cornerstone of chronic medical therapy is to prolong survival and improve quality of life. After initiation, close monitoring for hyperkalemia and renal insufficiency is warranted. Because of its short half-life, captopril is usually used in the acute setting (e. It tends to be nonproductive and involuntary, rarely resolving with altering the dose or specific agent. It involves soft tissue edema of the lips, face, tongue, and, occasionally, the oropharynx and epiglottis. However, consideration for the use of these agents must be weighed against the life-threatening nature of this complication. Side effects of hydralazine may include reflex tachycardia and rarely drug-induced lupus erythematosus. Although atenolol and metoprolol tartrate are widely available and relatively inexpensive, there is no evidence to support their use. It is important to note that these are relative contraindications, and particularly in the setting of reactive airway disease and peripheral arterial disease, the risks of β-blocker therapy must be weighed against their known benefits. Current recommendations are to start β-blockers in those who are clinically euvolemic. It is imperative to maintain contact with the patient and adjust vasodilator or diuretic therapy during titration. Every effort should be made to achieve target doses, but it is clear that even low doses of these drugs provide mortality and morbidity benefit. In practice, carvedilol (with its nonselective, β1-blocking vasodilator effects) may have greater blood pressure lowering than selective β1-agents such as metoprolol succinate. Advanced heart block is a contraindication to β-blockers unless a permanent pacemaker is present. Intensification of diuretic therapy and dose reduction or slower titration may be necessary. A basic metabolic panel should be checked within 1 week after initiation and monitored at regular intervals. Our approach is to initiate treatment with spironolactone because of its low cost and transition to eplerenone only in the setting of significant gynecomastia. Diuretics are used to maintain euvolemia and to improve symptoms, but their overuse can result in volume contraction, hypotension, resistance, and renal dysfunction. An effective and inexpensive initial regimen includes 20 to 120 mg of furosemide taken orally each day. If furosemide doses higher than 120 mg/d are needed, a second evening dose is typically prescribed. If this regimen fails, sequential nephron blockade with a thiazide diuretic can provide synergistic benefit. Torsemide in particular may have unique benefits in the form of antifibrotic effects and minimization of the postdiuretic sodium retention that complicates the use of loop diuretics with shorter half-lives. Whereas the Digitalis Investigation Group trial demonstrated the best clinical outcomes in patients with a serum digoxin concentration of 0. Sacubitril/valsartan is a combination pill that consists of a neprilysin inhibitor with angiotensin receptor blocker. Inhibition of neprilysin leads to the inhibition of natriuretic peptides and additional vasoactive peptides subsequently augmenting natriuresis and decreasing sympathetic tone, aldosterone, and cardiac fibrosis/hypertrophy. This remains a controversial subject and the decision of whether to use aspirin or not should be made on a case-by-case basis. In general, oral potassium supplementation is necessary to maintain serum potassium level in the ideal range of 4.

Patients in the borderline range are helped by clear limits and structure blood pressure your age plus 100 best buy for vasodilan, and they usually need relatively actively engaged clinicians so they can develop a sense of the clinicians as “real persons” (hence neither the psychoanalytic couch nor long silences are usually helpful) 4 arteria aorta generic vasodilan 20 mg without a prescription. Although patients with borderline psy- chologies suffer painfully and may thus evoke from clinicians a wish to respond to their neediness with increased availability and special adaptations to their pain prehypertension and alcohol order 20 mg vasodilan with mastercard, efforts by therapists to extend themselves or make exceptions to an established treatment frame (e. Deviations from the therapy frame may induce unmanageable regressions and painful levels of emotional disorganization in patients, and may lead therapists to feel depleted or overburdened. In short, the treatment frame provides the safety and security needed for both parties to engage in the work of therapy. A clinician must also be capable of sustaining his or her commitment to treat- ment over a long period. Patients with borderline organization may be exquisitely sensitive to shifts in the tone of their therapists and may become terrified that they will be abandoned. Their most disturbing symptoms may come back at times of separation from their clinicians—and, ironically, during treatment crises caused by their begin- ning to change for the better and to feel trust and hope in the therapeutic relationship (see also Bion, 1967; Grotstein, 2009; Rosenfeld, 1987). The transferences of such patients tend to be intense and difficult for the patients to see as transferential. When the clinician suggests that he is reacting as if the clinician had qualities like those of his mother, he may conclude, “Yes, it’s just my bad luck to have gotten a therapist exactly like her. Investigation of historical antecedents of the current behavior of a patient with borderline personality organization may not foster change; in fact, it may be used to rationalize not changing (e. Thus treatment should generally focus on the here-and-now, especially the ways in which the patient experiences the clinician (Grenyer, 2012; Stern et al. Therapies that are helpful to patients with borderline organization tend to be active and structured, and to include affective expressiveness from both patients and clinicians (McCarthy, Mergenthaler, Schneider, & Grenyer, 2011). Because such patients often know that they provoke strong reactions in other people, and because they tend to interpret neutral stimuli with a negative attributional bias (Daros, Zakza- nis & Ruocco, 2013), therapists who try to appear nonreactive can be experienced as insincere or dangerously out of touch. Although their specific recommendations differ, all advise giving primary attention to the therapeutic relationship, contracting against self-destructive behaviors, clarify- ing and respecting boundaries, educating patients about issues such as trauma and emotional regulation, keeping the focus on current challenges, and developing self- reflective capacities. All are sensitive to the special vulnerability of people in this group to issues of separation; all note the need for therapists to tolerate strong countertrans- ferences (especially feelings of helplessness and being overwhelmed); and most empha- size the importance of clinicians’ having ongoing consultation and support. Patients whose personalities are organized at the psychotic level need their clini- cians to be especially respectful, conversational, and down-to-earth. Patience is also critical: For patients in this range, language may be impoverished, and narrative history reporting may be impaired (Carter & Grenyer, 2012). In traditional psychoanalytic thinking, individuals whose personalities were conceptualized as at a psychotic level of organization were seen as needing supportive rather than exploratory therapy—that is, treatments supporting ego functions and defenses, rather than seeking to loosen ego defenses (Federn, 1952). But, realistically, there are supportive elements in explor- atory work and exploratory elements in supportive therapeutic relationships; and in Personality Syndromes—P Axis 27 the clinical literature, efforts to demarcate the differences between supportive and exploratory therapies have been problematic (see Appelbaum, 2005, 2008; Hellerstein, Pinsker, Rosenthal, & Klee, 1994; Pinsker, 1997; Rockland, 1989). We have observed, however, that clinicians experienced in working with patients with psychotic tendencies tend to answer questions, rather than acting blank or absti- nent; to give advice; to normalize and contextualize patients’ distressing experiences; to identify triggers of their worst states of mind; to educate them about elements of emotion, cognition, and behavior about which they may be confused; and to disclose elements of their own personalities and experiences that may make patients feel both more fully understood and less “crazy. They may need to monitor medication compliance and find ways of reinforcing basic self-care. They identify their patients’ strengths and build on them, rather than encouraging an opening-up, uncovering attitude that may terrify these fragile persons. Their overall stance is authoritative enough that the patients feel safe in their care and reassured that the clinicians will not be destroyed by the patients’ pathology. At the same time, the clinicians convey profound respect and a deeply egali- tarian attitude, so that the patients’ humiliation about symptoms (or even about simply needing help) can be minimized. They emphasize safety, and they focus on the issues of most concern to their patients, not necessarily those that strike the therapists them- selves as most troubling (Garrett, 2012; Sullivan, 1953, 1962). Further Comments on Personality Styles and Disorders There are many ways to distinguish psychologically between one person and another. Any clinician who gets to know a patient intimately finds that over time, that person no longer seems to fit a clear-cut diagnostic construct; the person’s individuality eventually becomes more salient. This is especially true for individuals at the healthier end of the severity spectrum, who commonly show mixes of personality styles. Nevertheless, it is clini- cally valuable to consider the predominant personality style or styles that best charac- terize a person.
