Levels of soluble ICAM-1 in premature and full-term neonates with infection.
BACKGROUND: Infection in the neonatal period is an extremely serious condition and diagnosis is difficult. C-reactive protein (CRP) is widely used as a marker of infection; however, its usefulness is limited in the early phase. The role of soluble intracellular adhesion molecule-1 (sICAM-1), an adhesion molecule, has been examined in recent studies as an early marker of neonatal infection with controversial results. AIM: Assessment of sICAM-1 concentrations and correlation with CRP, which is the currently used marker of infection, in order to use sICAM as an early diagnostic tool in neonates suspected for infection METHODS: Blood samples and blood cultures were obtained from two groups of pre-term and full-term neonates with clinical suspicion of infection prior to the initiation of antibiotics. The sICAM-1 and CRP values were compared with the corresponding noninfected ones (n = 10 each). RESULTS: The sICAM-1 levels were found increased in the group of both premature and term neonates with infection compared with the corresponding healthy ones (P < 0.0001). Prematurity combined with infection resulted in excessive increase of the levels of sICAM-1 in comparison with full-term infected newborns (p < 0.001). CRP values were normal in all samples except one in both full-term and premature infected neonates on day 1 of clinically suspected infection. Serial detection of CRP values on days 2 and 4 of infection revealed a pattern according to which CRP values in premature neonates continued rising, while in the group of full terms these values, after rising on the second day, lowered on day 4. CONCLUSIONS: Increased sICAM-1 levels can be detected early in both full-term and premature neonates with sepsis while CRP levels are within normal range at the same time. Assessment of sICAM-1 concentrations may be used as a diagnostic tool in neonates suspected for infection, resulting in earlier initiation of antibiotic therapy and therefore improving their outcome
Pancreatic pseudocysts
Improvements in imaging studies and a better understanding of the natural history of pancreatic fluid collections (PFCs) have allowed the different types to be clarified. Stratification of PFCs into subgroups should help in selecting from the increasing current available treatment options, which include percutaneous, endoscopic and surgical drainage. Percutaneous catheter drainage is safe and effective and should be the treatment of choice in poor-risk patients, and for infected pseudocysts related to acute pancreatitis. Endoscopic drainage should be the first management option in suitable pseudocysts related to chronic pancreatitis, if the necessary expertise is available. The high success rate and current low morbidity of elective open surgery mean that it is still the standard of management in this disease. Laparoscopic approaches are gaining favour, predominantly in drainage of collections in the lesser sac, and long-term data are awaited. The precise application of this modality will need to be critically compared with the low morbidity of mini-laparotomy, which is the current standard after non-operative treatment fails in these patients. It is essential to clearly stratify the different types of pancreatic pseudocysts, in particular with relation to acute or chronic pancreatitis, and perform a valid comparison of the different treatment modalities within groups. In this capacity a precise and transparent classification may provide valuable answers, in particular relating to optimal management according to pseudocyst type
Evolutionary History of Hunter-Gatherer Marriage Practices
Background: The universality of marriage in human societies around the world suggests a deep evolutionary history of institutionalized pair-bonding that stems back at least to early modern humans. However, marriage practices vary considerably from culture to culture, ranging from strict prescriptions and arranged marriages in some societies to mostly unregulated courtship in others, presence to absence of brideservice and brideprice, and polyandrous to polygynous unions. The ancestral state of early human marriage is not well known given the lack of conclusive archaeological evidence. Methodology: Comparative phylogenetic analyses using data from contemporary hunter-gatherers around the world may allow for the reconstruction of ancestral human cultural traits. We attempt to reconstruct ancestral marriage practices using hunter-gatherer phylogenies based on mitochondrial DNA sequences. Results: Arranged marriages are inferred to go back at least to first modern human migrations out of Africa. Reconstructions are equivocal on whether or not earlier human marriages were arranged because several African hunter-gatherers have courtship marriages. Phylogenetic reconstructions suggest that marriages in early ancestral human societies probably had low levels of polygyny (low reproductive skew) and reciprocal exchanges between the families of marital partners (i.e., brideservice or brideprice). Discussion: Phylogenetic results suggest a deep history of regulated exchange of mates and resources among lineages tha

Generalised Pustular Psoriasis (von Zumbusch type) following renal Transplantation. Report of a case and review of the literature
Generalized pustular psoriasis appears as an uncommon variant form of psoriasis consisting of widespread pustules on an erythematous background (von Zumbusch). A 39-year old male patient with a history of plaque psoriasis since the age of 9 who had an acute onset of generalized pustular psoriasis 12 days after he underwent renal transplantation is presented. Despite administered immunosuppression for transplantation the addition of cyclosporine A and methotrexate did not reverse the ongoing process of disease and the patient died on the 57th post-transplant day due to multiorgan failure following severe bone marrow suppression

Large retroperitoneal isolated fibrous cyst in absence of preceding trauma or acute pancreatitis
BACKGROUND: Isolated retroperitoneal cystic masses are uncommon with an estimated incidence of 1/5750 to 1/250,000. The majority present with size related symptoms, complications, or a mass. Approximately a third of patients are asymptomatic and are diagnosed incidentally. Aetiologies of retroperitoneal cystic masses (RPC) include mesenteric, omental, splenic and enteric duplication cysts. Neoplastic RPCs can be divided into epithelial (mucinous or serous cystadenoma), mesothelial (mesothelioma), germ cell (cystic teratoma) and cystic changes in a solid neoplasm (paraganglioma, neurilemmoma, sarcoma). CASE PRESENTATION: A 53 year-old man presented to us with abdominal pain related to a large mass in his left upper quadrant with associated anorexia and weight loss. He gave no history of previous trauma and denied having symptoms or a history of pancreatitis. He said he had felt this mass increasing in size over the course of several years. Clinical examination of his abdomen revealed a large firm left sided mass extending to his left upper quadrant. Imaging with computed tomography (CT) and magnetic resonance imaging cholangio-pancreatogram (MRCP) revealed a 13.7 cm × 12.2 cm × 10.9 cm cystic lesion in the retroperitoneum which was separate from the kidney, pancreas, spleen and bowel. At laparotomy, this mass was easily dissected from the surrounding viscera and was excised completely intact. Histopathological assessment found the mass to be a large fibrous pseudocyst with no epithelial lining. CONCLUSION: We present a rare case of an isolated large retroperitoneal fibrous pseudocyst unrelated to previous pancreatitis which was successfully managed with surgery.Julie Ahn, Manju D Chandrasegaram, Khaled Alsaleh, Benjamin L Woodham, Adrian Teo, Amithaba Das, Neil D Merrett, and Christos Apostolo
