Introduction Delayed massive hemorrhage induced by pancreatic fistula after pancreaticoduodenectomy is a rare but life-threatening complication.
The purpose of this study was to analyze the clinical course of patients with late hemorrhage, with or without sentinel bleeding,
to better define treatment options in the future.
Material and Methods From April 1998 to December 2006, 189 pancreaticoduodenectomies were performed. Eleven patients, including two patients referred
from other hospitals, were treated with delayed massive hemorrhage occurring 5 days or more after pancreaticoduodenectomy.
Sentinel bleeding was defined as minor blood loss via surgical drains or the gastrointestinal tract with an asymptomatic interval
until development of hemorrhagic shock. The clinical data of patients with bleeding episodes were analyzed retrospectively.
Results Eight of the 11 patients had sentinel bleeding, and seven of them had it at least 6 h before acute deterioration. Seven out
of 11 patients died, five out of eight with sentinel bleeding. No differences could be detected between patients with or without
sentinel bleeding before delayed massive hemorrhage. The only difference found was that non-surviving patients were significantly
older than surviving patients. Delayed massive hemorrhage is a common cause of death after pancreaticoduodenostomy complicated
by pancreatic fistula formation. The observation of sentinel bleeding should lead to emergency angiography and dependent from
the result to emergency relaparotomy to increase the likelihood of survival. 相似文献
Microdeletion syndromes are commonly transmitted as dominant traits and are frequently associated with variably expressed pleiotropic phenotypes. Nonlethal homozygous microdeletions, on the other hand, are very rare. Here, we delineate the fifth and so far largest homozygous microdeletion in nonmalignancies of approximately 400 kb on chromosome 4q11-q12 in a large consanguineous East-Anatolian family with six affected patients. The deleted region contains the beta-sarcoglycan gene (SGCB), the predicted gene SPATA18 (spermatogenesis associated 18 homolog) and several expressed sequence tags. Patients presented with a severe and progressive Duchenne-like muscular dystrophy phenotype, a combination of hyperlaxity and joint contractures, chest pain, palpitations, and dyspnea. 相似文献
OBJECTIVE: The present study was carried out to evaluate the safety and immunogenicity of the Haemophilus influenzae type b-CRM197 (Hib-CRM197) conjugate vaccine in relation to the change of adjuvant from aluminum hydroxide to aluminum phosphate (AlPO4). METHODS: The present study was a clinical phase II, observer-blind, randomized, multicenter, controlled study. Subjects were healthy infants aged 6-12 weeks, eligible for expanded program of immunization (EPI) routine vaccination and admitted to Hacettepe University Department of Social Pediatrics and Gülveren Health Center, Ankara. A total of 520 healthy infants were randomized in a 2:2:1 ratio to receive at either Chiron Hib/AlPO4 vaccine or VaxemHib (aluminum hydroxide adjuvant) vaccine or HibTiter (no adjuvant). Vaccines were administered simultaneously with routine diphtheria, tetanus and pertussis (DTaP) and oral polio vaccine (OPV) vaccines at 2, 4 and 6 months of age. Blood samples for anti-plain polysaccharide (PRP) antibody measurement were collected before the first vaccination and 1 month after the last vaccination. After each vaccination parents filled out a diary for 7 days. RESULTS: Out of 520 subjects enrolled, 514 received three doses and were included for safety analysis. Local and systemic reactions occurred with low and similar frequencies in all groups. Only erythema was more common in Chiron Hib/AlPO4 vaccine (19, 10, 11% in Chiron Hib/AlPO4, VaxemHib and HibTiter, respectively, P < 0.05). Nine serious adverse events were reported in seven cases of which none were related to vaccines. A total of 504 subjects were included in the immunogenicity analysis. The three vaccines were highly immunogenic and equivalent in terms of percentage of acquisition of long-term protective levels. The anti-PRP geometric mean titers were 9.9, 8.3 and 5.14 micro g/mL, respectively (P < 0.05). CONCLUSIONS: The use of aluminum compounds adjuvants in Hib-CRM197 conjugate vaccines does not impact the safety profile, while it does increase the magnitude of anti-PRP antibody titers. 相似文献
The occurrence and variability of domoic acid (DA) levels in wild Mytilus galloprovincialis samples, compared with the Pseudo-nitzschia spp. abundance and particulate DA (pDA) concentrations in relation to the environmental changes in the Golden Horn Estuary, Turkey from October 2018 to September 2019. Biotoxin analysis were performed by high-performance liquid chromatography with diode-array detection (HPLC–DAD). DA concentrations in particulate matter (pDA) and mussel samples were found between 0.090–0.685 µg L−1 and 0.905–2.413 µg g−1, respectively. Accumulation of DA in wild mussel samples could be the result of the increasing tendency of P.nitzschia spp. abundances between April and May. Maximum DA levels were detected in particulate matter when the salinity was measured as the lowest in May. Thus, it can be said that the DA production was driven by the significant salinity decrease in the GHE. This is the first attempt regarding the presence of DA in M. galloprovincialis samples collected from Turkish coasts.
Objective: To evaluate the effect of dopamine on thyroid hormone tests and prolactin (PRL) and to assess requirement for L-thyroxin (LT4).Methods: The infants (n?=?102) were divided into three groups (Group 1; received no dopamine, Group 2 received ≤25?mg/kg cumulative dose and Group 3; received >25?mg/kg cumulative dose). Blood samples were taken at 6–8 days (timepoint 1), 13–15 days (timepoint 2), and 4–6 weeks of life (timepoint 3).Results: Respiratory distress syndrome was higher in group 2 and 3. Patnet ductus arteriosus was higher in group 3 than in groups 1 and 2. Duration and cumulative dose in group 3 were higher than group 2. There was no difference between thyroid hormones that were taken after stopping infusion at timepoint 3 among all groups. No therapy with LT4 was needed. PRL levels were higher at timepoint 1 in group 1 than compared to group 2 and 3 (p?0.05), and no difference between group 2 and 3 (p?>?0.05). This difference was disappeared at following timepoints.Conclusions: The release of TSH, FT3, FT4 and PRL were not inhibited and prophylactic thyroid hormone treatment was not required in VLBW infants receiving dopamine infusions. 相似文献
Ornipressin is a vasopressin analogue that can cause potent splanchnic vasoconstriction. It has been shown that, in combination with albumin infusion, ornipressin is able to reverse hepatorenal syndrome. However, its clinical use is limited by possible severe ischaemic complications. In our case, a 47-year-old man received a right hemihepatectomy for cholangiocellular carcinoma. On post-operative day three, he developed hepatorenal syndrome with ascites, peripheral oedema and oliguria (250-500 ml/day). Serum creatinine was increased to 3.5 mg/dl. The patient was treated with terlipressin, another vasopressin analogue with fewer side effects than ornipressin, (1 mg every 4 h intravenously) and hydroxyethyl starch (500 ml/day). Urine output increased to 3000 ml/day, serum creatinine decreased to normal range within 4 days and ascites and oedema disappeared. We hereby report the first case of successful treatment of hepatorenal syndrome with terlipressin and hydroxyethyl starch, which appears to be a safe and effective treatment. 相似文献
