Absence of circulating products of oxygen derived free radicals in acute severe asthma.

Oxygen derived free radicals (ODFRs), generated by eosinophils, neutrophils, alveolar macrophages and mast cells, have been proposed as important mediators of inflammatory damage in asthma. We attempted to assess the role of these free radicals in patients with acute asthma by determining serum concentrations of phospholipid-esterified 9, 11 and the parent 9, 12-linoleic acid isomers (9, 11-LA, 9, 12-LA), using HPLC and diode array detection. The diene conjugate, 9, 11-LA, has been shown to be a sensitive and specific marker of free radical activity in other inflammatory conditions. Eight patients (6 female, aged 19-42 years) with acute asthma (mean peak expiratory flow 92 +/- (26) m (SEM) l.min-1, mean PaO2 8.4 (1.0) kPa were studied at 0, 6, 12, 24 and 48 hours after admission to hospital and again 4-6 weeks later. Initial blood samples were taken prior to the administration of oxygen or drug therapy. On admission, mean concentrations of 9, 11-LA and 9, 12-LA were normal at 18.0 (2.8) and 1024 (118) mumol.l-1. All subsequent 9, 11-LA serum concentrations were likewise in the normal range. The serum 9, 11-LA/9, 12-LA ratio was 1.9 (0.4) on admission and 1.6 (0.2) in convalescence (Normal Range 1.0-3.8). These findings in peripheral blood do not support a major role or oxygen derived free radical production in acute asthma, but local airway production cannot be excluded.

Rotavirus infection in a geriatric population.

An outbreak of gastroenteritis affected 19 of 34 geriatric patients and four of 23 staff assigned to the ward in a period of 3 1/2 weeks in January 1980. Fourteen of the 19 patients with gastroenteritis (17 were tested properly) and four of the ten asymptomatic patients (five asymptomatic patients were not tested) showed evidence of rotavirus infection by virus positivity and/or a significant antibody response to rotavirus. One of the four staff members with gastroenteritis showed serologic evidence (three were tested) of rotavirus infection. Nine of the 18 asymptomatic staff members (two remaining staff members were not tested) showed a fourfold rise in antibody to rotavirus but four had antibody titers of 1:32 or more. The patients had diarrhea for a mean of 2.6 days. Most of them had five or fewer diarrheal stools in one day. Six patients had a severe illness and two died. Thirteen of 15 symptomatic patients who had serum samples, collected during the acute and convalescent phases, tested manifested high titers (greater than or equal to 1:32) of complement-fixing antibody to rotavirus antigen.

Emergency minilaparotomy cholecystectomy for acute cholecystitis: prospective randomized trial--implications for the laparoscopic era.

This prospective controlled trial evaluates the efficacy of minicholecystectomy (MC) in cases of acute cholecystitis compared to that of conventional cholecystectomy (CC) and discusses its implications in the laparoscopic era. Sixty consecutive patients with acute cholecystitis were prospectively randomized into two groups: MC group (30 cases) and CC group (30 cases). The two groups were well matched with regard to age, sex, weight/height index, previous upper abdominal surgery, and APACHE II scores. The mean length of incision was 5.5 cm (range 4.5-9.0 cm) in the MC group compared to 13.5 cm (range 12-16 cm) in the CC group. No significant differences were found between MC and CC with regard to operative time (69.1 +/- 17.0 and 68.1 +/- 15.4 minutes, respectively; p = 0.82), operative difficulty on a 1 to 10 scale (5.2 +/- 1.5 versus 4.6 +/- 1.6, respectively; p = 0.177), and complication rate (11% and 17%, respectively; p = 0.19). Significantly lower analgesia requirements were noted in the MC group: 27.5 +/- 14.6 mg of morphine sulfate compared to 44.5 +/- 13.2 mg in the CC group (p < 0.001). In addition, the duration of hospital stay was significantly shorter for MC patients (3.1 +/- 1.0 days) than in CC patients (4.7 +/- 1.2 days) (p < 0.001). Twenty-two patients (73.3%) in the MC group were reported to return to normal daily activities 2 weeks after the operation, compared to only 12 (40%) in the CC group (p = 0.0028). MC is safe and applicable as an emergency procedure for acute cholecystitis. It is superior to CC in terms of convalescence and cosmesis. The results of MC in the setting of acute cholecystitis compare favorably with the published results of laparoscopic cholecystectomy.

Problems of cardiac patients in early recovery.

Most studies of the problems and information needs of patients describe these only for the period of hospitalization. In this study, however, the authors focused on the first 6 months after discharge. Eighty-two cardiac patients, admitted to a university hospital with a myocardial infarction (MI) or for coronary artery bypass surgery (CABS), were interviewed 6 months after discharge. Questions required them to describe problems they experienced in early recovery and what information they needed. All but one of the 82 patients stated they had experienced problems during the first 6 months after discharge. Most problems described concerned: emotional reactions (59%), their change in physical condition (59%), deleterious effects of treatment (56%) and convalescence (54%). Topics on which most patients needed additional or different information were: deleterious effects of the treatment (26%), physical condition (24%), risk factors (24%), convalescence (24%) and knowledge of the disease (24%).

Laparoscopic radical prostatectomy. Technical aspects and experience with 125 cases.

PURPOSE: The laparoscopic access for radical prostatectomy offers an alternative to the open surgical procedure with less morbidity. We report on our experience with 125 laparoscopic prostatectomies, especially with respect to making the laparoscopic approach a routine procedure and with a view to the oncological and functional results. MATERIAL AND METHODS: From June 1999 to September 2000, we performed 125 laparoscopic prostatectomies. These included only patients with cancer stages T1 or T2. The mean PSA concentration was 10.5 ng/ml. Forty-four percent of the patients had undergone previous abdominal and 19% previous transurethral surgery. For our laparoscopic prostatectomies we used the descending technique. Free-hand laparoscopic suturing and in situ knot-tying technique were used for the urethrovesical anastomosis. The mobilized specimens were removed in an endobag via a muscle splitting incision. RESULTS: All 125 procedures could be completed successfully. No case required conversion to open surgery. The average operating time was 255 min, the last 40 procedures taking 200 min only. Mean blood loss was 185 ml. Two patients (2%) required postoperative blood transfusion. After an initial learning curve, catheter remained in place for an average of 5.5 days, and the average postoperative stay in hospital was 8 days. Intraoperative complications were seen in 5 patients (4%). In 13 patients (10.4%) postoperative complications were observed. 86% of the patients are continent 6 months postoperatively. Preservation of the neurovascular bundle and sexual potency is possible. CONCLUSION: Laparoscopic radical prostatectomy is an ambitious procedure with a steep learning curve, especially for the laparoscopic dissecting and suturing technique. The excellent sight for dissection results in a reduced blood loss and faster convalescence with an overall lower morbidity. Also with regard to oncological and functional (continence) results the minimally invasive access is at least equivalent to the open procedure. In our opinion, laparoscopic prostatectomy will be the future method of choice for radical prostatectomy.

Risks and benefits of preoperative high dose methylprednisolone in surgical patients: a systematic review.

BACKGROUND: A single preoperative high dose of methylprednisolone (15 to 30 mg/kg) has been advocated in surgery, because it may inhibit the surgical stress response and thereby improve postoperative outcome and convalescence. However, these potential clinical benefits must be weighed against possible adverse effects. OBJECTIVE: To conduct a risk-benefit analysis using a meta-analysis, to compare complication rates and clinical advantages associated with the use of high dose methylprednisolone in surgical patients. METHODS: Randomised controlled trials of high dose methylprednisolone in elective and trauma surgery were systematically searched for in various literature databases. Outcome data on adverse effects, postoperative pain and hospital stay were extracted and statistically pooled in fixed-effects meta-analyses. RESULTS: We located 51 studies in elective cardiac and noncardiac surgery, as well as traumatology. Pooled data failed to show any significant increase in complication rates. In patients treated with corticosteroids, nonsignificantly more gastrointestinal bleeding and wound complications were observed; the 95% confidence interval boundaries of the numbers-needed-to-harm were 59 and 38, respectively. The only significant finding was a reduction of pulmonary complications (risk difference -3.5%; 95% confidence interval -1.0 to -6.1), mainly in trauma patients. CONCLUSION: For patients undergoing surgical procedures, a perioperative single-shot administration of high dose methylprednisolone is not associated with a significant increase in the incidence of adverse effects. In patients with multiple fractures, limited evidence suggests promising benefits of glucocorticoids on pulmonary complications.

[Analysis of relation between the usage of corticosteroid in treatment and arthralgia as a sequela of SARS patients].

OBJECTIVE: To analyze relation between the use of corticosteroids in the treatment for severe acute respiratory syndrome (SARS) patients and arthralgia as a sequela. METHODS: Clinical date of 30 SARS patients without other diseases in whom corticosteroid was used were reviewed including total dosage, duration of use, the highest dosage and its duration, and speed of reduction in dosage. The information about arthralgia was investigated one month after discharge of SARS patients from the hospital. RESULTS: The average total dosage of methylprednisolone was (4 244.16+/-2 292.30) mg, and the duration of use of the treatment was (25.36+/-5.88) days (ranging from 12 to 35 days). The maximum dosage was (321.33+/-174.03) mg/d, and the duration of its use was (7.73+/-4.08) days. The speed of reduction of dosage of corticosteroids was (21.33+/-10.18) mg/d. There were 26 of 30 patients (86.67 percent) experienced arthralgia symptom during convalescence. In 3.6 percent of patients arthralgia occurred within one month after SARS, 53.85 percent of the patients experienced low-grade arthralgia. By unifactor analysis, the total dosage and its duration of use, the highest dosage and its duration, speed of reduction of dosage of corticosteroids were correlated with the degree of arthralgia, respectively. The duration of arthralgia was correlated with the total dosage, the duration of high dosage, and high dosage. Age was not correlated with either the degree or the persisting time of arthralgia. The degree of arthralgia was only correlated with the total dosage, and the duration of arthralgia was correlated with administration time of glucocorticosteroids by multifactor analysis. CONCLUSION: There is a dosage- effect relation between the degree of arthralgia and the total dosage of corticosteroid, and a time-effect relation between the duration of arthralgia and length of the use of corticosteroids.

[Laparoscopic versus mini-cholecystectomy: analysis of hospital costs and social costs in a prospective randomized study].

The aim of the study was to calculate the hospital and social costs in relation to efficacy of clinical outcome, hospital stay and time off work in two groups of patients randomly treated with laparoscopic or mini-cholecystectomy. One hundred and eighty-one patients with simple, symptomatic gallstone disease were included in the study; of these, 9 cases were excluded because of conversion to conventional cholecystectomy. Eighty-six cases underwent laparoscopic cholecystectomy and 86 mini-cholecystectomy. Operative time (median time: 35 minutes) and hospital stay (median stay: 3 days) were the same for both surgical procedures. The median time off work was 10 days for laparoscopic cholecystectomy and 20 days for mini-cholecystectomy (P = 0.007). Hospital expenses showed a saving of 820.48 euros for each patient undergoing mini-cholecystectomy. Since laparoscopic cholecystectomy is associated with a shorter period off work, it seems to be cheaper with a daily saving of 164.96 and 146.51 Euros per patient, according to cost/effectiveness and cost/utility analyses, respectively. Consequently, although laparoscopic cholecystectomy shows a better outcome in terms of socioeconomic aspects and patient compliance, in an attempt to rationalize hospital expenditure, we would advocate mini-cholecystectomy for those patients who do not need to return to work early.

Evaluation of arthropod-borne viruses and other infectious disease pathogens as the causes of febrile illnesses in the Khartoum Province of Sudan.

The relative importance of arthropod-borne and other disease pathogens as the cause of an outbreak of febrile illnesses was assessed during August 1988, following severe flooding in Khartoum, Sudan. A total of 200 patients with acute febrile illness and 100 afebrile controls were enrolled in the study during October and November 1988; at the Omdurman Military Hospital, Khartoum, Sudan. Sera were tested for IgM and IgG antibodies to six arthropod-borne viruses by an enzyme-linked immunoabsorbent assay, and for similar antibodies to Lassa fever, Crimean-Congo hemorrhagic fever, and Ebola and Marburg viruses by an indirect fluorescence assay. Thick and thin blood smears were examined microscopically for malaria parasites, and fecal and blood specimens were tested for bacteria by standard culture methods. Among the acute and convalescent sera collected from 67 febrile patients, five cases were caused by sandfly fever Sicilian (SFS), six by sandfly fever Naples (SFN), and 12 by unidentified phleboviruses. Of 233 remaining unpaired, acute-phase sera collected from cases and controls, 49 (21%) had IgM antibodies to SFS or SFN, RVF, West Nile (WN), and Chikungunya (CHIK) viruses. Forty-three (22%) of 192 febrile cases and two of the 100 afebrile controls were positive for Plasmodium falciparum, and bacterial enteropathogens were associated with 25 (13%) cases and four controls. These data indicated that phleboviruses and to a lesser extent, WN, P. falciparum, and enterobacterial pathogens were causes of acute febrile illnesses following the 1988 flood in Khartoum, Sudan.

Prognostic indicators estimated by (99m)Tc-GSA in acute liver damage.

A prognostic estimation formula of acute liver damage was evaluated by using clinical data and technetium-99m-diethylenetriaminepentaacetic acid-galactosyl-human serum albumin ((99m)Tc-GSA) scintigraphy in order to determine operability for orthotopic liver transplantation (OLT). Forty-six patients hospitalized for acute liver damage were divided into survival (n=35) and non-survival (n=11) groups. Univariate and multivariate analyses were used to identify significant factors that affected prognosis. Logistic regression analysis was performed to predict prognosis with effective factors. Ten independent factors with significant differences were identified and further analyzed for significance by logistic regression analysis. Among the 10 factors, age and LHL15/HH15 were identified as having meaningful differences for predicting convalescence. The following formula was developed: A negative value for R indicates non-survivals, and a positive value indicates survivals. The mortality rate was calculated as=1/(1+e(R)). The sensitivity was 0.909, specificity was 1.000, and accuracy was 0.978. The reliability of this formula was as good as that of another formula presented previously by the Intractable Liver Diseases Study Group of Japan. The use of (99m)Tc-GSA for estimating the prognosis of acute liver damage is useful, especially before the onset of hepatic encephalopathy.

Laparoscopic radical versus partial nephrectomy: assessment of complications.

PURPOSE: We evaluated the short-term morbidity and complications of laparoscopic radical nephrectomy (LRN) compared with laparoscopic partial nephrectomy (LPN). MATERIALS AND METHODS: From May 1998 to May 2002, 114 patients were identified with a single unilateral sporadic renal tumor and a normal contralateral kidney. These individuals had undergone LRN (35) or LPN (79). RESULTS: The LRN and LPN groups were analyzed for age, sex, American Society of Anesthesiologists score and body mass index. Mean tumor size in patients undergoing LRN and LPN was 2.8 +/- 1.2 (range 0.9 to 4.5) and 2.5 +/- 1.0 cm (range 1 to 4.5), respectively (p = 0.17). There were no differences between the 2 groups in terms of mean hospital stay, blood transfusion or surgical complications. There was no difference in mean preoperative and postoperative serum creatinine in patients in the LPN group. Mean postoperative serum creatinine was significantly higher than the mean preoperative level in patients in the LRN group (1.51 +/- 0.22 vs 1.18 +/- 0.37 mg/ml, range 0.6 to 2.4, p = 0.02). In each group 1 case was converted to open surgery due to bleeding. CONCLUSIONS: LPN is associated with similar postoperative convalescence and complications compared with LRN. The increase in serum creatinine noted in patients undergoing radical extirpation supports the use of LPN when clinically indicated.

The "common cold" in frail older persons: impact of rhinovirus and coronavirus in a senior daycare center.

OBJECTIVE: To evaluate the incidence and impact of rhinovirus and coronavirus infections in older persons attending daycare. DESIGN: Prospective descriptive study. SETTING: Three senior daycare centers in Rochester, New York. PATIENTS: Frail older persons and staff members of the daycare centers who developed signs or symptoms of an acute respiratory illness. MEASUREMENTS: Demographic, medical, and physical findings were recorded on subjects at baseline and during respiratory illness. Nasopharyngeal specimens for viral culture as well as acute and convalescent sera for coronavirus 229E enzyme immunoassay (EIA) were obtained for all illnesses. RESULTS: During the 44 months of study, 352 older persons experienced 522 illnesses. Thirty-five (7%) of 522 cultures were positive for rhinovirus and 37 (8%) of 451 serologies were positive for coronavirus 229E infection. The clinical syndromes associated with rhinovirus and coronavirus infection were similar and characterized by nasal congestion, cough, and constitutional symptoms. No patient died or was hospitalized, but approximately 50% had evidence of lower respiratory tract involvement. The average illness lasted 14 days. During the same period, 113 staff developed 338 respiratory illnesses. Eight percent were identified as coronavirus and 9% as rhinovirus. Cough, sputum production, and constitutional symptoms were significantly more common among older persons. CONCLUSIONS: Rhinovirus and coronavirus 229E are common causes of moderately debilitating acute respiratory illnesses among older persons attending daycare.

Laparoscopic total and partial nephrectomy-the new standard?

Laparoscopic radical nephrectomy has been shown in long-term follow-up to provide shorter patient hospitalization and effective cancer control with no significant difference in survival compared with open radical nephrectomy. The major technical issue for success of laparoscopic partial nephrectomy is hemostatic control, and several techniques have been developed to improve control. Laparoscopic partial nephrectomy continues to evolve along two therapeutic technical avenues: hilar clamping with ischemia versus no hilar clamping. The benefits of laparoscopy for the kidney have clearly been demonstrated in terms of less pain, decreased convalescence, and decreased narcotic requirements. With short-term outcomes demonstrating laparoscopic partial nephrectomy as an efficacious procedure, the role of laparoscopic partial nephrectomy should continue to increase.

[Acute pain service--another in-hospital specialty?].

Realizing that achievement in postoperative pain treatment was not satisfactory, central health authorities in USA, United Kingdom and Australia have published guidelines for managing acute pain. Establishing acute pain services is thought to be one of the means of improving pain relief in the individual patient. Development and research are secured and achieved results may be presented currently. At this moment, introduction of acute pain services is at a preliminary stage in Denmark, and consequently an overview of results obtained from abroad is given including pain treatment techniques, management and safety measures, as well as visions concerning the impact of optimal pain relief upon convalescence. We conclude that the introduction of acute pain services is bound to optimize postoperative patient care and might well prove to be a significant factor in reducing postoperative morbidity.

Nutritional status and clinical outcome in elderly female surgical orthopaedic patients.

The possible relationship between nutritional status and clinical outcome following orthopaedic hip surgery was investigated. The nutritional status of 60 elderly female patients admitted for elective total hip replacement (THR) and emergency fractured neck of femur surgery (FNF) was measured over time. Specific measures of clinical outcome, including well-being and functional status, were monitored during hospital stay and at 4, 8 and 26 weeks following discharge. Patients were allocated to a high nutritional risk group where any three of the following were less than the 5th percentile value: serum albumin, haemoglobin, triceps skinfold thickness, mid-upper arm muscle circumference and body weight. Using this definition, malnutrition was present in 4% of THR patients and 41% of FNF patients. It was found that the high risk patients had significantly longer convalescence periods, (median stay 27.5 days compared with 0 days, P < 0.0009), and a greater proportion were dependent upon walking frames at 6 months (46% compared with 11%, P < 0.01). Fifty percent of the high risk patients had been living independently prior to admission, in contrast only 29% had returned to their homes at 6 months after discharge. The results indicate an apparent link between clinical outcome and nutritional status based upon the allocation procedure employed, which has the potential for ensuring cost-effective nutritional intervention.

Clinical and financial analyses of ectopic pregnancy management at a large health plan.

STUDY OBJECTIVE: To compare three treatment options for ectopic pregnancy-laparotomy, laparoscopy, and methotrexate-including clinical aspects, costs, and reproductive outcomes. DESIGN: Retrospective review of outpatient and inpatient records of all patients with a diagnosis of ectopic pregnancy insured by Fallon Community Health from 1990 to 1995. SETTING: Multispecialty group practice and a university-affiliated private hospital. PATIENTS: One hundred seven women treated for ectopic pregnancy. INTERVENTIONS: Thirty-six women were treated by laparotomy, 58 by laparoscopy, and 13 by single-dose intramuscular methotrexate. Data from the chart review were analyzed to define differences among the three groups with respect to several predetermined outcome variables: initial symptoms, risk factors, human chorionic gonadotropin levels, size of ectopic gestation, procedure types, rupture rates, surgical outcomes and morbidity, failure rates, length of convalescence, reproductive outcomes, and costs. MEASUREMENTS AND MAIN RESULTS: The incidence of ectopic pregnancy was 8.6/1000 reported pregnancies. Initially, 38% of surgical patients had laparoscopic treatment, but by 1995 the figure reached 100%. From 1994 to 1995, 13 (29%) of 45 pregnancies were treated with single-dose methotrexate. Compared with laparoscopy, length of stay was significantly longer for laparotomy (3.1 vs 1.3 days), as was recuperation time (2.4 vs 4.6 wks). Laparotomy had similar rates of total complications as laparoscopy (13.9% vs 10.3%). The rate of treatment failures (persistent trophoblastic activity) were 2.7% and 3.4%, respectively. The rate of persistence for laparoscopic salpingostomy was 6.1%. Methotrexate therapy resulted in no tubal ruptures or treatment failures. Two of 13 women required a second injection. The only complication of methotrexate therapy was mild leukocytopenia in one patient. Total charges were similar for laparotomy and laparoscopy ($6720 vs $6840). Outpatient methotrexate therapy cost significantly less than the two surgical procedures (average $818/case, p < 0.001). Laparotomy resulted in similar intrauterine pregnancy rates as laparoscopy (66% vs 77%), and similar repeat tubal pregnancy rates (17% vs 7%). CONCLUSION: The results of this study support laparoscopy and methotrexate as efficacious, safe, and cost effective for the treatment of ectopic pregnancy compared with laparotomy. Reproductive outcomes were similar among the three groups.

[A case of leptospirosis caused by Leptospira borgpetersenii serovar sejroe infected in Bali Island, Indonesia].

We report a patient with leptospirosis caused by Leptospira borgpetersenii serovar Sejroe infection on Bali Island, Indonesia. This 33-year-old Japanese man had stayed at a resort hotel on the island from July 8 to July 13 2004. At the hotel, he swam in the pool, walked barefoot, and lied down in the grass. He developed a high fever and headache 7 days after completing his trip, and was admitted to our hospital on July 23. On admission he showed conjunctival suffusion and complained of myalgias. Laboratory findings included granulocytosis and elevated CRP. Plasmodium spp. were not found in blood smears, and no pathogenic bacteria were isolated from blood or fecal cultures. We diagnosed the patient as leptospirosis upon detection of slender coiled organisms with characteristic morphology by darkfield examination of blood sample. Minocycline 100 mg i.v.b.i.d. showed excellent efficacy. A microscopic agglutination test (MAT) during the convalescent stage demonstrated a significant increase in antibodies against L. borgpetersenii serovar Sejroe, confirming the diagnosis of leptospirosis. Despite occurrence of a pandemic of leptospirosis in certain Southeast Asian countries including Indonesia, information concerning pandemic disease is limited. In addition serovars of "imported" cases representing infection in pandemic areas differ widely from those in domestic cases. Adequate laboratory support therefore is crucial for accurate diagnosis of leptospirosis.
