Most importantly, tip support should be determined by palpation and noting the degree of resistance and recoil. Lack of support noted by ease of downward compression of the middle nasal vault may indicate complete loss of underlying septal support, which will dictate the method of reconstruction. Severe loss of nasal tip support may indicate total loss of caudal septal support. The three-quar- ters view aids in confirming the assessment made with the aforementioned views. Deviation of the caudal septum may cause canting of the tip, lobule, or columella. Severe caudal septal deformities can result in foreshortening of the nose and loss of the normal columellar/lobular angle. The entire caudal septum should be palpated to localize the deformity (anterior septal angle, midcaudal septum, or posterior septal angle). Dorsal or caudal deviation of the septum may correspond to distorted areas of the middle vault, tip, and nasal base. The internal angle between the septum and upper lateral cartilage is normally 15 degrees. In such cases, inspection may reveal dynamic collapse of the upper lateral car- tilages with inspiration.

Present turning of the defbrillator function as a simple step to improving the quality of the last few days of life. Emergency deactivation can usually be accomplished by placing a magnet over the defbrillator box; the magnet must remain in place for continued deactivation. Fluid overload should be treated with diuretics such as loop, thiazide, and aldosterone antagonists. For example, 4 hours at one infation in every two cardiac cycles (‘ in 2’) would be the relatively rapid weaning in a patient that might be expected to tolerate removal. Care should be taken to monitor patients closely in the frst 24 hours post IaBp removal looking for evidence of decompensation. Prognosis the -year survival following Ctx is 85%, with a conditional median survival of 3 years. Patient selection for heart transplantation the selection of patients for Ctx is difcult. It is important to identify those at the highest risk of mortality prior to listing, as Ctx has a -year mortality of 75%. Risk factors and contraindications Whenever possible, intrinsic organ damage should be diferentiated from reversible abnormalities secondary to heart failure. Immediate post-transplant management the perioperative management of heart transplant recipients ofers sev- eral unique challenges to the cardiothoracic intensivist. Management • epicardial pacing wires are placed on the atrium and ventricle at the time of surgery. Myocardial stunning the total ischaemic time of the donor heart (cross-clamp on donor heart to cross-clamp of after implantation) is directly correlated with postoperative myocardial performance. While the shorter the time the better, transplant teams aim for an ischaemic time of <4 hours with an i mortality observed for total ischaemic time >5 hours. Some surgeons also use a left atrial line to allow direct monitoring of left-sided flling pressures. Opportunistic infection prophylactic antibiotics are used in the early postoperative phase. Cardiac allograft rejection rejection can be either cellular or antibody mediated, although in the non-sensitized patient, cellular rejection is the most common form of acute rejection. Endomyocardial biopsy In 973, philip Caves frst described transvenous endomyocardial biopsy to diagnose cardiac allograft rejection. Most centres continue to use this tech- nique in the early phase after Ctx, when the risk of rejection is highest, and while immunosuppressive therapy is slowly weaned to maintenance doses. Ltx was frst performed in 963 by James Hardy, although the patient only survived for 8 days. Multiple other attempts were thwarted by rejection until Joel Cooper performed the frst successful single Ltx in 983, followed by double Ltx in 986. Targets • tidal volume 6–8mL/kg • peep 4–8cm/H2O (note: a high peep may cause a deterioration in bronchial anastomotic healing, barotrauma, or over-infation of the native lung in single Ltx) • peak inspiratory pressure <30cmH2O • pulmonary toilet 2-hourly • Chest drain <5cm/H2O suction • Fibreoptic bronchoscopy if atelectasis/infltration seen, or prior to extubation (to assess bronchial anastomosis and colour of distal bronchus). For that reason, infection needs to be rigorously excluded for the accurate and reproducible interpretation of pulmonary allograft biopsies. Ill-defned peri-hilar and lower zone nodules and septal lines may raise the suspicion of rejection, although a normal appearance does not exclude an episode of rejection. Immunosuppression the majority of lung transplant centres now employ an immunosuppressive strategy that uses a combination of tacrolimus and mycophenolate, with a reducing dose of corticosteroids. Infection Infection is very common after lung transplantation due to denervation, bronchial anastomosis, impaired mucociliary function, immunosuppres- sion, and bronchiolitis obliterans occurring as a chronic rejection. International guidelines for the selection of lung transplant candidates: 2006 update. The number of procedures reported to be performed worldwide is declining, with 50% of centres performing only one such transplant per year. The procedure the donor heart and lungs are harvested with minimal handling, with the heart fushed with cold cardioplegia solution, and the lungs with modifed Collins solution. Care should be taken to keep the donor trachea as short as possible because of the limited vascularity of the area. Prognosis although the prognosis has improved in recent years, the -year mortality is 728%, and around half of patients are dead at 3 years. However, patients surviving the frst year have an average life expectancy of nearly 0 years.

It is unfortunately a common event with a high mortality, and survival rate to discharge home is typically <0%. Principles of management • Efective cardiopulmonary resuscitation (Cpr) with minimal interruption • Optimize oxygenation • Early defbrillation • Appropriate drug treatment. Early, aggressive management of these patients has potential to signifcantly infu- ence their outcome and neurological status. Treatment of seizures Seizures are common following hypoxic neurological insult: • Insufcient evidence for prophylactic treatment. Temperature control pyrexia is common in the 48 hours following cardiac arrest; poor neuro- logical outcome has been associated with temperatures of 38°C and above. Both trials demonstrated improvement in anoxic neurological injury, relating to improved functional outcomes and reduced mortality. Due to the adverse physiological efects of cooling, it is important to assess the risk of beneft versus harm on an individual basis. Despite advances in medicine over the last 30 years neither the incidence nor mortality of the condition has changed. Up to 5% of cases are the result of Coxiella burnetii (Q fever), Bartonella,Leg ionella,Mycoplasma, and Chlamydia. Diagnosis the Duke criteria for diagnosis of infective endocarditis require 2 major or  major and 3 minor or 5 minors: Major criteria • positive blood cultures: either typical organism in 2 sets, or persistently positive blood cultures (3+ sets >2 hours apart), or single positive blood culture for Q fever/phase  IgG antibody titre > :800. Minor criteria • predisposing factors • pyrexia > 38°C • positive blood cultures • Echocardiogram that do not meet major criteria • Vascular or immunological signs. Investigations • Blood cultures: at least 3 sets taken 30 minutes apart from separate sites. In patients in whom a high suspicion remains despite previously negative fndings should be rescanned 7–0 days later.

Localized or focal encephalitis is the most common presenta­ tion of toxoplasmosis buy paroxetine 30mg lowest price. This is in contrast to primary central nervous system lymphoma and toxoplasmosis in which mass efect may occur cheap paroxetine 10 mg amex. Neurologic deficits typically persist in survivors proportionate to the disease severity at the time of presentation. Other parasitic infections such as those caused by Trypano­ soma brucei, T cruzi, and Toxoplasma gondii are among those with a protozoan etiol­ ogy. He has also had a rapid loss of weight, night sweats, and frequent low­ grade fever. Other significant findings included the presence of oral thrush, splenomegaly, bilateral lower extremity weakness, and hyperrefexia. The India ink stain, cryptococcal antigen test, and culture for fungi were nega­ tive. He underwent a cadaveric kidney trans­ plantation 10 months ago, and his immunosuppressive regimen includes pred­ nisone and azathioprine. The lesions are generally bilateral, asymmetric, nonenhancing, and peri-ventricular or subcortical in distribution. A negative serologic test for toxoplasma-specific IgM would add additional support to the exclusion of toxoplasmic encephalitis. The most appropriate empiric therapy is ampicillin (the drug of choice for Listeria), with ceftriaxone and/or vancomycin. Empiric vancomycin and ceftriaxone are recommended for the treat­ ment of meningitis in patients 2 to 50 years of age. She has a history of a cerebral vascular accident and residual neurological defcits and has been hospitalized fo r the past 3 weeks.

The patient is currently on the third day of ciprofoxacin fo r empiric treatment of her recurrent urinary tract infection. She has an elevated temperature despite antibiotic treatment and has developed fngemia as well. To learn antimicrobial treatment strategies that may reduce the occurrence of antimicrobial resistance. Co nsidertions This is a 74-year-old woman with significant residual neurologic deficits and renal insufficiency after sufering from a cerebral vascular accident. When a patient does not respond to antimicrobial therapy, it is generally important to determine if another source of infection is present and/or if the antibiotic treatment regimen is inappropriate or insuficient against the microorganisms responsible for the infection. Since the same bacteria is isolated from her urine and her blood stream, the infection is severe, systemic, and inadequately controlled with the current antimi­ crobial regimen. In addition, fungal species isolated on blood culture strongly sug­ gests that fungal sepsis is contributing to the worsening clinical picture. Infection with drug-resistant organisms contributes to prolonged hospitalization, higher hos­ pital costs, and a poorer prognosis. The emergence of antibiot­ ic-resistant bacteria is a significant problem in intensive care units. The inappropriate administration of broad-spectrum antibiotics can lead to even more dificult-to-treat infections. The therapy is started based on clinical suspicion of infection based on physiologic parameters. Patients with suspected infections are treated with broad-spectrum antibiotics aimed at most probable organisms that are causing the infections with narrowing (or discontinuing altogether) of the antibiotic coverage as soon as culture results become available, or if no infections are documented. Similarly, duration of treatment may be shortened when patients with uncomplicated infections show clinical improvement/resolution. Consequently, antibiotics are one ofthe most common therapies utilized in the intensive care unit. The rea­ son for this elevated level of drug-resistant infections is multifactorial. In addition to patient-specific risk factors, there are other general factors such as excessive antimicrobial use, poor aseptic technique, and inadequate hand hygiene of health-care providers that con­ tribute to the increased infectious risks. The inappropriate choice and duration of antibiotics therapy can also contribute to the problem by selecting for resistant bac­ teria overgrowth and infection. Microbial resistance is increasing in bothgram-negative andgram-positive bacteria. The inadequate empiric coverage of these resistant bacteria can lead to a higher morbid­ ity and mortality. However, the inappropriate use of broad-spectrum antibiotics can lead to the increase in emergence of resistant bacteria. Thus, the challenge to the physician is to use antibiotics that will cover the resistant bacteria without over­ treatment that can lead to resistance. When a patient is septic, antibiotics must be initiated promptly, preferably, within 1 hour of diagnosis. Each hour of delay over the next 6 hours has been shown to contribute to a decrease in survival of 7. The initial choices of the preemptive antimicrobial therapy need to adequately address the potential infective organisms to minimize the mortality associated with the infection. Inadequate initial therapy usually involves either the failure to cover a specific microbe or utilizing antibiotics to which the organism is resistant. It is obligatory that before antibiotics are started, cultures should be obtained. Once the culture isolates with their associated antibiotic sensitivities are identified, the antimicrobial therapy should be immediately adjusted to more narrow-coverage antibiotics that have bactericidal activity against the bacteria. This de-escalation therapy allows for treatment ofthe infection while reducing the risk of antimicrobial resistance. Another key component in the selection of antibiotic choice is based on the basic pharmacokinetics (necessary dosage to achieve adequate levels, tissue pen­ etrance, etc). This is important so that under-dosing does not occur, as this can lead to an increase in the emergence of resistant organisms. This is particularly important in patients with renal insuficiency; adjustments of drug dosing and frequency of administrations are often needed when patient are receiving hemodialysis. Infected high­ risk patients should be started on combination broad-spectrum antibiotics based on presumed infectious sources and local antibiograms (Table 18-1). Antibiotics have difrent tissue penetrations and should be taken into account when treating infections. Source control of the infection, such as abscess drainage, should be performed immediately. Different resistance rates are found at diferent hospitals, so antibiograms that show local antibiotic susceptibility should be used as a guide for initiating therapy that will cover local resistance. Once the cultures return with antibiotic susceptibility, antibiotic therapy should be de-escalated in spectrum and duration.
