Critical care issues in stroke and subarachnoid hemorrhage.

The outcomes of devastating neurological emergencies such as stroke and subarachnoid hemorrhage may be measurably improved by timely treatment in a neurointensive care unit (NICU). Optimal care requires a multidisciplinary approach, with attention to a wide range of treatment issues. This review examines the key therapeutic concerns in the NICU management of acute ischemic and hemorrhagic stroke and subarachnoid hemorrhage, including mechanical ventilation, blood pressure management, cardiac monitoring, intracranial pressure assessment, vasospasm, seizures, sedation, fluids, electrolytes, and nutrition. The discussion of mechanical ventilation includes rapid sequence induction and intubation, indication for intubation and extubation, and prognostic factors in mechanical ventilation. Differing blood pressure management concerns in hemorrhagic and ischemic events are discussed, and specific target blood pressures and pharmacologic interventions are reviewed. The discussion of cardiac monitoring includes concurrent stroke and cardiac ischemia and arrhythmias, cardiac imaging, anticoagulation, and vasopressor therapy. The importance, monitoring and management of cerebral blood flow and intracranial pressure (ICP) are discussed, and strategies for treatment of elevated ICP are outlined in detail. The discussion of vasospasm includes evaluation, prophylaxis, and treatment with medications, hypervolemic hemodilution, and angioplasty. Management of seizure and status epilepticus in stroke and subarachnoid hemorrhage are reviewed and current algorithms are presented. The management of fluids, electrolytes and enteral nutrition are also reviewed.

Small incision external levator repair: technique and early results.

PURPOSE: To describe a new surgical technique and early results of external levator repair performed through a small skin incision. METHODS: A chart review of consecutive patients undergoing small incision external levator repair was conducted. This modified external levator repair was performed through an 8-mm eyelid crease incision. Patients with unilateral or bilateral aponeurogenic blepharoptosis were candidates for the technique. Patients with excessive horizontal upper eyelid laxity and those requiring blepharoplasty in addition to blepharoptosis surgery did not undergo this technique. Patients who underwent previous upper eyelid surgery or concurrent brow surgery were excluded from the review. Preoperative measurements included upper eyelid margin reflex distance, levator function, and degree of dermatochalasis, as well as Goldmann visual field results. Outcome measures included incidence and type of intraoperative complications, postoperative upper eyelid position (including margin reflex distance, eyelid contour, and symmetry), incidence and type of postoperative complications, and revisions or additional necessary surgery. RESULTS: Twenty-eight eyelids of 17 patients met study inclusion criteria. Preoperative margin reflex distance +/- SD averaged 0.8 +/- 0.4 mm. Average length of follow-up was 28 +/- 5 weeks (range, 15 to 52 weeks). No significant intraoperative complications occurred. Postoperative margin reflex distance averaged 3.7 +/- 0.3 mm. Two eyelids were mildly undercorrected, and one demonstrated moderately peaked contour postoperatively. Satisfactory eyelid position and contour were achieved in 25 of 28 treated eyelids. No patient elected reoperation. CONCLUSIONS: Early results demonstrated that small incision levator repair is safe and generally effective. This minimally invasive external levator repair is useful for a carefully selected subset of patients with aponeurogenic blepharoptosis.

HIV and thrombosis: a review.

The array of clinicopathologic factors associated with acquired immune deficiency syndrome (AIDS) patients continues to increase and surprise many physicians. The recent literature contains reports of thrombotic episodes occurring in patients with human immunodeficiency virus (HIV) infection. Various abnormalities predisposing to a hypercoagulable state have also been reported in AIDS patients including the presence of antiphospholipid antibodies and the lupus anticoagulant; deficiencies of protein C, protein S, heparin cofactor II, and antithrombin and increased levels of von Willebrand factor, and d-dimers. These abnormalities correlate with the severity of HIV-associated immunosuppression as measured by the CD4 cell counts and with the presence of concurrent infectious or neoplastic diseases. The authors reviewed the medical literature and describe various abnormalities predisposing to a hypercoagulable state in AIDS patients along with the management of such complications. This issue is important because deep venous thrombosis (DVT), pulmonary embolus (PE), or thrombosis at other sites can develop in patients with AIDS who are ambulatory and have no known risk factors for pathologic thrombus formation, providing another challenge in an already difficult clinical situation. This also provides a strong rationale for careful prospective studies focusing on the prevalence and risk factors involved in the development of thromboembolic complications in patients with AIDS.

Intrathoracic and concurrent orthopedic injury associated with traumatic rib fracture in cats: 75 cases (1980-1998).

OBJECTIVE: To characterize rib, intrathoracic, and concurrent orthopedic injuries, and prognosis associated with traumatic rib fracture in cats. DESIGN: Retrospective study. ANIMALS: 75 cats. PROCEDURE: Medical records from January 1980 to August 1998 were examined for cats with traumatic rib fracture. Signalment, cause of trauma, interval from trauma to evaluation at a veterinary teaching hospital, referral status and date, method of diagnosis, duration of hospitalization, number and location of rib fractures, presence of flail chest, costal cartilage involvement, intrathoracic and concurrent orthopedic injury, and clinical outcome were reviewed. RESULTS: Median age was 3 years. Twenty-five (58%) cats with reported cause of trauma were injured by interaction with another animal. Forty-seven (78%) cats that were treated survived. Cats that died had a median duration of hospitalization of < 1 day. Ten (13%) cats had flail chest. Sixty-five (87%) cats had intrathoracic injury (median, 2 injuries). Nine (100%) cats without detected intrathoracic injury that were treated survived. Thirty-five (47%) cats had concurrent orthopedic injury. Cats with flail chest, pleural effusion, or diaphragmatic hernia were significantly more likely to die than cats without each injury. CONCLUSIONS AND CLINICAL RELEVANCE: Traumatic rib fracture in cats is associated with intrathoracic and concurrent orthopedic injury. Aggressive treatment of cats with traumatic rib fracture is warranted, because the prognosis is generally favorable. Diagnosis and treatment of intrathoracic injury associated with traumatic rib fracture in cats should precede management of concurrent orthopedic injury.

Consistency of a double PAPNET scan of cervical smears.

OBJECTIVE: To determine the reproducibility and accuracy of the PAPNET system in finding and presenting abnormal and atypical cells. STUDY DESIGN: To assess the potential variation of a double PAPNET scan on the same cervical smear, 516 cervical smears from women with abnormal histologic diagnoses were scanned twice via PAPNET and reviewed by two independent examiners in a double-blind trial. RESULTS: The false negative rate of 5.7% in conventional screening was reduced to 0.4% and 0.8%, respectively, by PAPNET testing. The resulting concurrence of the first and the second PAPNET reviews was 99.2%, indicating the accuracy, sensitivity and consistency of this supplemental test. CONCLUSION: The results obtained demonstrate the reproducibility and accuracy of the system in finding and presenting abnormal and atypical cells.

Current approaches of neoadjuvant chemotherapy in cervical cancer.

Despite remarkable improvement in clinical management, the survival of cervical cancer patients has shown only minor progress in the last decade, particularly in patients with advanced and high-risk disease. Multimodal treatment option has been investigated, such as the concurrent use of chemotherapy and radiation, neoadjuvant chemotherapy and radical hysterectomy, or neoadjuvant chemotherapy followed by radiotherapy. Recently, a flow of randomized clinical trials have demonstrated a benefit from the concurrent chemoradiation for the treatment of the cancer of the cervix. This review will summarize the role and benefit of neoadjuvant chemotherapy in combination with sequential or concurrent radiotherapy and radical surgery for treatment of cervical cancer.

The interrelationship of tropical disease and mental disorder: conceptual framework and literature review (Part I--Malaria).

Substantial interactions between tropical diseases and psychiatric illness have long been recognized, but the impact of biological factors in the field of cross-cultural psychiatry has been less well studied than psychosocial factors. In reviewing the literature at the intersection of tropical medicine and psychiatry in order to summarize the existing data base in this field, a generalized interactive model informed by the theoretical contributions of George Engel, the WHO Scientific Working Group on Social and Economic Research, Arthur Kleinman, P. M. Yap, Edward Sapir and others has been developed to serve as a conceptual framework for this analysis of the literature and to guide further research. The clinical literature of tropical medicine and psychiatry which recognizes the significance of concurrent tropical disease and mental disorders is reviewed along with the more specific literature on malaria and concomitant psychiatric illness. Many authors have focused on the role of organic mental disorders, especially in connection with cerebral malaria, but several have also addressed psychosocial parameters through which the interrelationship between malaria and a full range of mental disorders is also mediated. The effects of malaria may serve as biological, psychological or social stressors operating in a cultural context which precipitate or shape features of psychiatric symptomatology. Psychiatric illness may likewise precipitate an episode of malaria with typical symptoms in a patient with a previously subclinical infection. Implications of the literature and this generalized interactive model are considered as they apply to clinical practice, public health and the application of social science theory in medicine.

Assessing vision behind cataract--a review of methods.

The clinician involved in cataract assessment is often faced with a deterioration in visual performance which may or may not be totally attributable to the cataract. Neural changes may occur concurrently and contribute toward the reduced performance. This paper reviews the methods which attempt to discriminate between changes due to cataract development and changes produced by neural degeneration. New techniques have been developed with more emphasis on quantitative rather than qualitative assessment. These techniques are discussed critically with particular reference to their ability to distinguish between the contributions of optical and neural change. This has particular application in predicting the visual outcome after cataract surgery.

Enhanced length of stay management through monitoring of discharge planning parameters.

Traditional data collection in discharge planning programs has been largely retrospective, measuring the patient's length of stay and unnecessary hospital days at the point of discharge. Although the data collection is useful, it does not lend itself to corrective actions on a concurrent basis. Carney Hospital has developed a data base that monitors patient status daily in order to identify when a length of stay problem is developing and when corrective actions are succeeding. The Patient Tracking System is an interactive computer report utilized by Continuing Care staff, Utilization Review staff, and clinical managers on the patient care units. It is a caseload register that operates from the admission transfer discharge (A/T/D) system of the hospital and sorts inpatients by discharge planning status, length of stay, discharge planning worker, and nursing unit. It is the basis for a weekly management review that identifies numbers of patients and average length of stay to date of key groups of patients proven to impact the overall length of stay in the hospital. Carney Hospital has successfully utilized this system to alert managers to any length of stay "creep," to identify the sources of the length-of-stay problem, and to mobilize key personnel to take corrective actions. The system is easy to use and is an effective length-of-stay management tool.

Appropriateness of admission and the last 24 hours of hospital care in medical wards in an east London teaching group hospital.

OBJECTIVE: To assess the rates of inappropriateness of admission and last day of care on adult medical wards in an east London hospital, to identify associations with any inappropriateness and to assess what services need to be improved or provided if patients assessed as "inappropriate" are to be more appropriately placed in the future. DESIGN: From the patients' medical notes, nursing notes and ward charts, a trained reviewer with nursing and university qualifications collected concurrent information about each patient's first 24 hours as an in-patient and about the last 24 hours of care preceding discharge. Patients were also interviewed before discharge and 7-10 days after discharge, and their health status and level of satisfaction about the discharge process assessed. SETTING: The three adult medical wards at the Homerton Hospital in Hackney, east London. This hospital is within the St Bartholomew's Hospital Teaching Hospital Group. SUBJECTS: The case-notes of a random sample of 625 adult in-patients were reviewed. END POINTS: Appropriateness of admission and last day of care. MAIN OUTCOME MEASURES: The main instrument used was the Appropriateness Evaluation Protocol (AEP). This is an instrument devised to assess the appropriateness of adult patient admission to, and specific days of care in, acute hospital beds through case-note review against a structured set of criteria. RESULTS: The study presented here reported that 31% of in-patient admissions to adult medical wards in an east London hospital were inappropriate, and also that 66% of the last days of stay were inappropriate. CONCLUSIONS: There is clearly considerable room for improvement in relation to cooperation between service providers in order to maximise efficient bed use. Delays due to waiting for medications from pharmacy, and the combination of more "inappropriate" cases wanting help from social services after discharge with the fact that many of them were still in hospital because they were waiting for these services to be organized, suggest that inappropriateness could be reduced through increased efficiency or increased provision in these areas. The study reported here is unique in its inclusion of patient interview data.

Spironolactone-induced agranulocytosis: a case report.

A 43-year-old woman with liver cirrhosis and hepatocellular carcinoma was admitted for the chief problem of ascites. Laboratory data revealed a leukocyte count of 3.8 x 10(9)/L on the second day of admission. Spironolactone was prescribed for diuresis beginning on the third day. Routine blood tests on the tenth day disclosed marked leukopenia (1.8 x 10(9)/L). Four days later, the leukocyte count was still 1.8 x 10(9)/L and a differential count revealed agranulocytosis (neutrophils, 0.25 x 10(9)/L). Eight days after withdrawal of spironolactone, the leukocyte count returned to normal (leukocytes, 4.9 x 109/L; neutrophils, 1.76 x 10(9)/L). On review of the patient's clinical condition, concurrent medication, and previous reports, we highly suspected that this episode of agranulocytosis was caused by spironolactone. Unlike four previously reported cases, this one did not involve furosemide, which is reported to be associated with leukopenia and agranulocytosis.

Coronary arteriovenous fistulas: collective review and management of six new cases--changing etiology, presentation, and treatment strategy.

We considered it worthwhile to review the literature of the last decade (1985-1995) to answer the question whether the etiology and the clinical picture of coronary arteriovenous fistulas (CAVFs) have changed. Furthermore, new therapeutic modalities such as percutaneous transcatheter embolization have been developed. We tried to define the place of these techniques in the therapeutic arena. Clinical presentation and management of six patients with eight congenital CAVFs and 76 subjects with 96 congenital and acquire I CAVFs taken from a review of the recent literature are presented. Sixty-three review subjects (78%) were treated medically with one fatal case. Ligation of the fistula was achieved by surgical techniques in 10% of review subjects, while percutaneous transcatheter embolization (PTE) was performed in nine patients (12%). Percutaneous transcatheter embolization techniques are being increasingly used in the treatment of CAVFs. The etiology of CAVFs has a tendency to show alterations toward the acquired pathogenesis. In 64% of the review subjects the fistula was congenital in origin, and in 36% it had an acquired cause. Among the patients of the current review, the clinical presentations were 55% asymptomatic, 34% chest pain (anginal or atypical), and 13% congestive heart failure. The CAVFs of our six patients are all congenital in origin. In the current review, the clinical presentation showed a trend toward increasing chest complaints (34%) compared with the review (10%) published in the mid 1970s. This may be due to a higher mean age, and hence increased concurrent coronary artery disease due to aging compared with the review population of two decades ago.

Outcome of and prognostic indicators for dogs and cats with pneumoperitoneum and no history of penetrating trauma: 54 cases (1988-2002).

OBJECTIVE: To determine the outcome of and prognostic indicators for dogs and cats with pneumoperitoneum and no history of penetrating trauma. DESIGN: Retrospective study. ANIMALS: 43 dogs and 11 cats. PROCEDURE: Medical records of dogs and cats with radiographic evidence of pneumoperitoneum and no history of penetrating trauma were reviewed. Information collected included signalment, previous medical problems, initial complaint, duration of illness, physical examination findings, radiographic findings, laboratory abnormalities, abdominocentesis results, bacterial culture results, concurrent diseases, hospitalization time, and outcome. Abdominal radiographs were reviewed, and radiographic severity of pneumoperitoneum was classified. For those animals that underwent exploratory laparotomy, time from admission to surgery and results of histologic examination of biopsy specimens were recorded. RESULTS: 24 (44%) animals survived and were discharged from the hospital, but none of the variables examined was associated with whether animals survived. Rupture of the gastrointestinal tract was the cause of pneumoperitoneum in 40 animals. However, cause and location of gastrointestinal tract rupture was not associated with whether animals survived. Twenty-three of 40 (58%) animals that underwent exploratory laparotomy survived, compared with only 1 of 14 animals that did not undergo surgery. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that pneumoperitoneum in dogs and cats without any history of penetrating trauma is most commonly associated with rupture of the gastrointestinal tract and requires immediate surgical intervention. Even when appropriate treatment is instituted, the shortterm prognosis is only fair.

An evaluation of postoperative pain management in pediatric patients at a university teaching hospital.

In recent years, pediatric pain management has begun to receive some much deserved attention. Many misconceptions regarding pediatric pain management have resulted in infants and children receiving inadequate pain control after surgical or invasive procedures. The purpose of this investigation was to evaluate appropriateness of pain management practices, emphasizing drug therapy, in children with acute pain after a surgical procedure. Analgesic use and pain assessment methods were evaluated for 30 pediatric patients undergoing an invasive medical procedure or surgery. Data were collected concurrently on the use of pain medications, potential for drug interactions/duplication of therapeutic classes, pain assessment, patient response to medication, and any adverse effects experienced by a child. Twenty patients (67%) had concurrent orders written for multiple analgesics on admission to the nursing unit. Only 6 of these 20 order sets (30%) designated specific indications for use. Ten of the 14 remaining order sets (those without specific directions for use) contained at least one medication that was inappropriate to treat the expected level of postoperative pain. Fifty-four percent of total physician orders fell outside study criteria for appropriate dosing and scheduling frequency. Patient records revealed that nursing administered the lowest ordered dose 47% of the time, and a failure to consistently conduct pain assessments or document patient response to medication. Eight patients (27%) experienced allergic-type reactions, whereas 7 patients (23%) experienced adverse drug reactions. Information gathered from this review will be used to determine if a need exists to develop hospital guidelines or adopt the Agency for Health Care Policy and Research guidelines for acute pain management in children.

Mobile (cellular) phone use and driving: a critical review of research methodology.

Studies have examined possible effects of concurrent mobile phone use on driving performance. Although interference is often apparent, determining the implications of such findings for 'real world' driving is problematic. This paper considers some relevant methodological issues including the definition of procedures and terms, operationalization of task elements, sampling of task components, and the provision of experimental controls. Suggestions are made about how methodological rigor could be improved.

Impact of hemoglobin on survival of cervical carcinoma patients treated with concurrent chemoradiotherapy is dependent on lymph node metastasis findings by magnetic resonance imaging.

The objective of this study was to confirm whether hemoglobin (Hb) levels during chemoradiotherapy are associated with survival in patients with locally advanced cervical carcinoma and to assess impact of the Hb level on survival according to lymph node (LN) metastasis. A retrospective review of 85 cervical carcinoma patients treated with concurrent chemoradiotherapy was conducted. The stage of disease ranged between FIGO stage IB and stage IVA. Disease-free and overall survivals were evaluated by univariate and multivariate analyses. After median follow-up of 35.7 months, 24 patients developed recurrence of disease and 14 patients died from their disease. Stage, LN metastasis, and squamous cell carcinoma antigen and Hb levels during chemoradiation were correlated significantly with survival (P < 0.05). Maintenance of Hb above 10.0 g/dL was associated with better survival (P < 0.05). However, no such benefits were observed in patients with LN metastasis by magnetic resonance imaging (MRI). Multivariate Cox regression hazard model showed that Hb levels during chemoradiation were an independent prognostic factor in patients without LN metastasis by MRI. Maintenance of Hb during chemoradiation is of benefit in cervical carcinoma patients without LN metastasis but not with LN metastasis by MRI.

Mastoid obliteration: autogenous cranial bone pAte reconstruction.

OBJECTIVE: To review the outcome in consecutive patients who have undergone complete epitympanic and mastoid obliteration and concurrent tympanic membrane reconstruction over a 53-month period. STUDY DESIGN: Retrospective review. SETTING: Tertiary referral center. PATIENTS: Sixty-two ears in 56 sequential patients undergoing mastoid obliteration with major indications including recurrent infection, debris trapping in the canal wall-down cavity, intolerance of water exposure, calorically induced vertigo in an existing cavity, a semicircular canal fistula, and inability to wear a hearing device. Thirty-six ears in 33 patients who underwent second-stage surgery for ossicular reconstruction during the same time period are also reviewed. INTERVENTION: Transplanted autogenous cranial bone is used to induce osteoneogenesis resulting in complete obliteration of the epitympanic and mastoid spaces while maintaining a mesotympanic space. MAIN OUTCOME MEASURES: Success of obliteration, incidence of symptoms prompting intervention, hearing outcome, incidence of recurrent cholesteatoma, and incidence of eustachian tube dysfunction necessitating treatment and need for revision surgical procedures.RESULTS Complete take of the bony obliteration occurs in over 95% of cases; 90% of treated patients enjoy complete absence of original symptoms, whereas symptoms improved in the remainder. For over 95% of patients, existing eustachian tube function has been adequate after obliteration. To date, no patient has required revision surgical intervention. CONCLUSION: Mastoid obliteration with autogenous cranial bone is a safe and extremely effective option for treatment of problematic canal wall-down mastoid cavities. Surgical techniques that include sterile harvest of the cranial bone graft mixed with antibiotic, revision of the cavity to expose viable native bone, inclusion of the epitympanic spaces in the obliteration, and complete coverage of the pAte with autogenous fascia have proven critical to successful outcome.

Recreational use of sildenafil by HIV-positive and -negative homosexual/bisexual males.

OBJECTIVE: To conduct an epidemiologic review of sildenafil in homosexual and bisexual males focusing on concurrent use with club drugs and/or antiretroviral medications. DATA SOURCES: A search of MEDLINE was conducted (1966-September 2003), and an extensive manual review of journals was performed using the key search terms club drugs, sildenafil, antiretrovirals, and HIV. STUDY SELECTION AND DATA EXTRACTION: All articles identified from the data sources were evaluated and information deemed relevant was included. DATA SYNTHESIS: Several epidemiologic studies have reported that sildenafil is abused in a recreational fashion, typically with agents commonly known to be "club drugs." In this setting, sildenafil may reverse the impotence-inducing effects of the club drugs and restore sexual capabilities. Many implications of both recreational and nonrecreational use of sildenafil exist in relation to HIV disease. Concern has been raised regarding the potential effects on high-risk sexual practices. Also, several researchers have documented interactions between sildenafil and various club drugs, as well as with antiretrovirals intended for HIV disease. CONCLUSIONS: Serious concerns exist regarding the concurrent use of sildenafil with antiretrovirals and/or club drugs. Clinicians prescribing sildenafil to patients receiving protease inhibitor-containing antiretroviral regimens should be aware of the potential for reduced sildenafil metabolism with resultant adverse effects. Additionally, untoward effects may also occur when sildenafil is used concurrently with various club drugs including amyl and butyl nitrites ("poppers").
