The authors report their experience with 56 percutaneous nephrostomies (PCNs) performed on an outpatient basis on 55 patients. Complications included pain that required use of parenteral medication in four patients, bleeding in three that resolved spontaneously, and shaking chills or fever in 12. This last complication, considered to be a sign of sepsis and treated with antibiotics, occurred more frequently than the 1.4%-4.5% infectious complication rate reported in the literature. Antibiotic use during and after PCN significantly decreased the likelihood of sepsis. In the high-risk group, antibiotic administration during and after PCN decreased the risk of developing signs of sepsis from 50% to 9%. On the basis of the authors' results and the findings in the literature about antibiotic prophylaxis, guidelines are recommended to improve the safety of PCN as an outpatient procedure. In the majority of instances PCN should still be considered to be more safely performed as an inpatient procedure at this time.

Sepsis, an important cause of hospital mortality, continues to be a diagnostic and therapeutic challenge. To define more clearly the impact of encephalopathy on the course of sepsis, the various clinical signs of sepsis, blood culture results, and mortality rates were examined in relation to mental status in septic patients. Patients were classified as having an acutely altered mental status due to sepsis (AAMS), preexisting altered mental status (PAMS), or normal mental status (NMS). Twenty-three (307/1333) percent of the study patients had an acutely altered sensorium secondary to sepsis. Patients with AAMS had a higher mortality (49%) than patients with PAMS (41%) or patients with NMS (26%) (p less than .000001). Multivariate analysis disclosed that altered mental status, hypothermia, hypotension, thrombocytopenia, and the absence of shaking chills were independent predictors of increased mortality in the sepsis syndrome. Patients with Gram-negative bacteremia (28%) were as likely to have AAMS as patients with Gram-positive bacteremia (25%) or patients with negative blood cultures (23%). In summary, alterations in mental status are common in septic patients, and are associated with significantly higher mortality.

The patient was a 59-year-old man who had been in hospital suffering from aplastic anemia with transfusion hemosiderosis. Sudden onset of weakness, shaking chills and headache was observed after his staying out overnight on July 25, 1981. His temperature was 39.3 degrees C and he complained of abdominal pain and abdominal distension. His blood pressure dropped to a dangerous level and tonic convulsions that had begun in the upper body gradually extended to the whole body and he died 23 hours after his return. V. vulnificus was isolated by the blood culture performed before death. During his stay away from the hospital, he had eaten raw cuttlefish, which was considered to be the source of infection. V. vulnificus is one of the halophilic marine vibrios and is isolated frequently in summertime from the sea foods and sea water near Japan. It has been disclosed that the presence of underlying diseases such as liver cirrhosis, hemochromatosis can predispose a person to fatal sepsis by V. vulnificus. In this case, besides leukocytopenia, the presence of hemosiderosis induced by many transfusions was considered to be a major cause leading to the fulminating course of the disease.

Despite the low morbidity and mortality of laparoscopic cholecystectomy, trauma and infection have been reported. Such complications can produce a misleading clinical picture, as in two cases we observed. Case 1. A symptomatic 56-year-old female patient underwent laparoscopic cholecystectomy. During the operation, the gall bladder ruptured and the contents had to be aspirated from the abdominal cavity. The patient complained of hepatalgia 2 weeks after the operation, then was not seen again for more than 1 year when fever and hepatalgia did not respond to symptomatic treatment. An inter-hepato-renal collection (6 cm in diameter) was punctured under echography. Aspirate culture yielded Pseudomonas aeruginosa. Adapted antibiotic therapy was unsuccessful and surgery was required to empty the abscess then remove a fibrous conjunctive tissue formation. Case 2. A 55-year-old female patient with a history of complete remission after mammectomy for breast cancer underwent laparoscopic cholecystectomy in 1991. Two days after the operation, fever (39 degrees C) was accompanied by abdominal defence. Biliary peritonitis due to imperfect suture of the bile duct was repaired followed by peritoneal lavage-drainage. Per-operative blood samples revealed type 6 Pseudomonas aeruginosa. Despite adapted parenteral antibiotics, fever persisted at 39 degrees C and intense jaundice was observed. A second laparoscopy 14 days later showed inflammatory narrowing of the main bile duct which was drained into a small bowel loop. Eight days later computed tomography revealed multiple abscess in the liver. Transparietal cholangiography was performed and showed that the contrast medium entered the abscesses via the biliary canals. The state of sepsis persisted, jaundice worsened and hepatic encephalopathy developed with obnubilation and flapping tremor. After 1 month of general antibiotherapy, no improvement was seen on computed tomography images and needle biopsy of an abscess led to the identification of resistant type 6 P. aeruginosa. Antibiotics were adapted and administered iv with no clinical improvement. Selective catheterism of the hepatic artery via the femoral access was performed to allow intra-hepatic antibiotic delivery. Three weeks later clinical situation remained unchanged when acute respiratory distress highly suggestive of pulmonary embolism led to death. Autopsy was not performed. In both of these rare cases of infectious complications due to P. aeruginosa after laparoscopic cholecystectomy, the source of contamination remained unknown. Nosocomial infection was suspected.

Patients who use PermCath as the vascular access for long-term hemodialysis are occasionally confronted with catheter-related infections. Recently, we have treated 17 patients suffering from PermCath-related sepsis. The clinical presenting features were leukocytosis in 14/17, high fever and shaking chill during dialysis in 12/17, and signs of exit site infection in 3/17. No shock was found. All patients received clinical evaluation to exclude infection sources other than from blood and inside the catheter, such as pulmonary, genitourinary, hepatobiliary and cutaneous systems. Blood drawn from both PermCath and peripheral vein was sent for bacterial culture. Bacterial culture of the blood samples from PermCath revealed Staphylococcus sp. in 7/17, Pseudomonas sp. in 5/17, Enterobacter sp. in 4/17, Streptococcus sp. in 1/17. Fourteen blood samples from peripheral vein showed positive culture results identical to those from PermCath, but negative study were noted in three other patients. The patients were divided into two treatment groups: Group I: systemic antibiotics without PermCath removal in 7, Group II: "locked-in" retention in addition to systemic anti-biotics in 10. Antibiotics were empirically chosen according to bacteriological studies. In the "locked-in" retention treatment, antibiotics were retained into both the inflow and outflow PermCath lumens in the exact volume of each lumen for 24 hours. The antibiotics solutions were replaced on a daily basis. The same antibiotics were also given intravenously. Duration of treatment depended on clinical progression and follow-up blood culture results and ranged between 13 and 24 days. The schedule of dialysis was not changed through the period of PermCath-related sepsis. The sepsis was cured in all group II cases but not in 2 of group I and resulted in mortality in these 2 patients. The PermCaths were preserved in 5/7 in group I with two mortality cases and all except one preserved in group II patients without mortality. We suggested that "locked-in" retention in addition to systemic antibiotics is the treatment of choice for the patients with PermCath-related sepsis. This method also preserves the functional integrity of PermCath, which is the lifeline vascular access of the patients with exhausted native vessels.

A previously healthy 15-year-old female was admitted to our hospital complaining of nausea and vomiting. She did not complain of diarrhea. A physical examination revealed a lower right quadrant abdominal tenderness without rebound or spontaneous pain and a knocking pain of the costovertebral angle. A high fever, knocking pain of costovertebral angle, and urinary findings including Gram's stain, lead us to suspect a urinary tract infection, cefotiam was administered intravenously. Spiking fever with shaking chills continued for three days, and three sets of blood cultures were positive for Salmonella Oranienburg, but her urine culture was negative. Her history was taken again, revealing an intake of a processed squid product. The product was confirmed by the local public health center to be Salmonella Oranienburg. Finally food poisoning by Salmonella Oranienburg with sepsis was diagnosed. With cefotiam she became better and was discharged from the hospital on the 10th hospital day. During admission to the hospital she did not experience any diarrhea, and her stool culture was negative. Epidemics of Salmonella Oranienburg food poisoning are relatively rare in the literature. In Japan, one has arisen as a result of contamination of a processed squid product in March 1999. However, there have been no cases without so-called gastroenteritic symptoms (abdominal pain and diarrhea) who were previously healthy and developed sepsis caused by Salmonella Oranienburg, reported in Japan. Even in previously healthy patients, with an epidemic situation of non-typhoidal salmonellosis, salmonella sepsis must be ruled out. Among such cases, those who present with spiking fever and shaking chills should be given antibiotic therapy after taking appropriate cultures.

Platelet-derived microparticles (PMPs) are released from platelets through the platelet activation by high shear stress, collagen, or calcium ionophore (A23187). PMPs are observed in patients with acute myocardial infarction, thrombotic thrombocytopenic purpura, hemolytic uremic syndrome, heparin-induced thrombocytopenia and other thrombotic disorders, but the importance of circulating PMPs in the pathogenesis of these diseases is still debated. Numbers of PMPs are usually determined by flowcytometry (FCM), but easier and reproducible PMP assay systems are needed. To develop a better ELISA for PMPs, we used antibodies against the platelet antigens anti-GPIb (NNKY5-5), anti-GPIIb/IIIa (NNKY2-11, anti-CD41), anti-GPIX (KMP-9), and anti-CD9 (NNKY1-19). PMPs were detected with all combinations of these antibodies, but the ELISA having the highest and most specific absorbance was obtained with a combination of KMP-9 (capture antibody) and NNKY5-5 (detecting antibody). PMPs in blood samples were measured by ELISA and FCM. ELISA correlated with PMPs quantitated by FCM. By shaking ELISA plates during incubation, nonspecific binding of platelets was eliminated. The level of PMPs was not increased in diabetes mellitus, thrombotic thrombocytopenic purpura, antiphospholipid syndrome, or sepsis. The concentration of PMP was elevated in hemolytic uremic syndrome. Activated PMPs were absorbed to 0.8 microm filter, but circulating PMPs were not absorbed. These results suggest that activated PMPs are likely to adhere to leukocytes or endothelial cells at the activation site and that the circulating form of PMPs are likely to be a residue of activated PMPs. To detect only the activated form of PMPs, a new ELISA needs to be developed, and it will likely use a combination of antibodies that detect platelet activation markers such as P-selectin (CD62P) or activated GPIIb/IIIa.

We report a patient with bacterial translocation-associated sepsis who was healthy and did not have any related-background. The 57-year-old male had been well until 16 hours before admission, when nausea and vomiting gradually developed and increased in intensity. In the morning of May 22, 2002, he had shaking chills, temperature of 38.6 degrees C and watery diarrhea, and was admitted to Kawasaki Municipal Hospital. On admission, temperature was 40.7 degrees C but otherwise physical examination revealed no particular abnormality. Laboratory data showed total white blood cells of 28,400/microliter, platelet count of 130,000/microliter, creatinine of 2.0 mg/dl and C-reactive protein of 7.5 mg/dl. 1 g of cefmetazole was administered every eight hours. In the early morning of May 23, he suddenly went into shock. At that time, laboratory findings revealed total white blood cells of 33,700/microliter, platelet count of 65,000/microliter, C-reactive protein of 24.9 mg/dl, creatinine of 5.6 mg/dl and serum potassium concentration of 5.7 mEq/l. Gram positive cocci and gram negative rods were isolated from blood culture obtained on admission. Cefmetazole was changed to 1.5 g/day of imipenem/cilastatin sodium and 600 mg/day of clindamycin. In addition, hemodialysis and endotoxin removal with an adsorbent column using polymyxin B were performed. Bacteria detected in the blood on admission were identified as Klebsiela oxytoca and Enterococcus faecium. Imipenem/cilastatin sodium and clindamycin were continued for 13 days. The patient recovered fully and was discharged on June 11. This case suggests that bacterial translocation-associated sepsis might occur even in a hitherto healthy adult.

Amiodarone-associated thyrotoxicosis (AAT) is often poorly tolerated owing to underlying cardiac disease, and it is frequently refractory to conventional medical treatment. The goal of this study was to describe the patient characteristics, management, and outcomes of all the patients treated surgically for AAT at a single institution. We conducted a retrospective chart review of all patients managed surgically for AAT (April 1985 through November 2002) at the Mayo Clinic in Rochester, Minnesota. Altogether, 29 men and 5 women, ages 39 to 85 years (median 60 years), treated with amiodarone for 3 to 108 months underwent near-total or total thyroidectomy. Frequent symptoms were worsening heart failure, fatigue, weight loss, and tremor. Altogether, 12 patients failed medical management of their AAT, and 21 received no preoperative medical therapy. One patient had been successfully managed medically but required definitive treatment. Common indications for operation were the need to remain on amiodarone, cardiac decompensation, medically refractory disease, and severe symptoms, both hyperthyroid and cardiac, necessitating prompt resolution. The median+/-SD American Society of Anesthesiologists (ASA) classification (1 = healthy through 5 = moribund) was 3.00+/-0.58. A total of 27 specimens had histology consistent with AAT. Complications included death (n = 3), rehospitalization (n = 3), symptomatic hypocalcemia (n = 2), pneumonia (n = 2), cervical hematoma (n = 1), prolonged ventilatorywean (n = 1), and stroke (n = 1); one patient developed hypotension, adult respiratory distress syndrome, and sepsis. Of the 31 surviving patients, 25 (80%) remained on amiodarone postoperatively. The median follow-up was 29 months, at which time all surviving patients were free of hyperthyroid symptoms. Thyroidectomy is an effective treatment for AAT but has a high incidence of perioperative morbidity and mortality. The cardiovascular co-morbidities and high operative risk in this group of patients may account for the increased complication rate.

Classic galactosemia is caused by impaired galactose-1-phosphate uridyltransferase (GALT EC 2.7.712). If discovered and treated within the first days of life, the acute problems of hepatocellular damage, sepsis, and death are prevented. However, chronic problems such as ataxia, tremor, dyspraxic speech, and ovarian failure may occur. To determine whether screening newborns before discharge from the nursery for GALT deficiency is feasible and whether acute and chronic signs could be prevented by earlier intervention, we developed a simplified "breath test." We quantitated total body oxidation of C-D-galactose to CO2 in expired air by normal newborns between 2 h and 2 mo of age and compared their results to older children with GALT deficiency. We found no differences in total body galactose oxidation (TBGO) among normal newborns up to 48 h of age, but a 2-fold rise in TBGO developed during their first 2 wk of life. Older children with galactosemia had significantly less oxidative capacity than normal newborns. We conclude that newborn breath testing for total body galactose oxidation is feasible before discharge from nursery. It has potential utility for both preventing acute neonatal toxicity and determining the mechanisms producing long-term complications such as ovarian failure, dyspraxia, ataxia, and tremors.
