New series of Ag, Cd(II), Ce(III), Co(II), Cr(III), Fe(III), Ni(II) and Pb(II) complexes with (E)-N-(4-(2- hydroxybenzylideneamino) phenylsulfonyl) {S.S} have been synthesized. These compounds have been characterized by different physico-chemical techniques like, melting point, elemental analysis, FT-IR, UV spectroscopy, 1H NMR spectroscopy, conductance measurements, magnetic susceptibility and mass spectral analysis. The metal ions concentrations have been determined using inductively coupled plasma mass spectrometry (ICP-MS). Spectroscopic studies suggest coordination most of complexes in a regular octahedral arrangement in 2L:1M molar ratio by two N azomethine and two OH phenolic from Schiff base {S.S} in the form of [ML2(H2O)2], M metal, L ligand {S.S}. Complexes have been screened for their antibacterial {Gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa)}, {Gram positive bacteria (Bacillus subtilis and Sterptococcus pneumoniae)} and antifungal (Aspergillus fumigates and Candida albicans) showing promising antimicrobial biological activity.

Pancreatic pseudocyst or a cystic tumor of the pancreas?

Pancreatic pseudocysts are the most common cystic lesions of the pancreas and may complicate acute pancreatitis, chronic pancreatitis, or pancreatic trauma. While the majority of acute pseudocysts resolve spontaneously, few may require drainage. On the other hand, pancreatic cystic tumors, which usually require extirpation, may disguise as pseudocysts. Hence, the distinction between the two entities is crucial for a successful outcome. We conducted this study to highlight the fundamental differences between pancreatic pseudocysts and cystic tumors so that relevant management plans can be devised. We reviewed the data of patients with pancreatic cystic lesions that underwent intervention between June 2007 and December 2010 in our hospital. We identified 9 patients(5 males and 4 females) with a median age of 40 years(range, 30–70 years). Five patients had pseudocysts, 2 had cystic tumors, and 2 had diseases of undetermined pathology. Pancreatic pseudocysts were treated by pseudocystogastrostomy in 2 cases and percutaneous drainage in 3 cases. One case recurred after percutaneous drainage and required pseudocystogastrostomy. The true pancreatic cysts were serous cystadenoma, which was treated by distal pancreatectomy, and mucinous cystadenocarcinoma, which was initially treated by drainage, like a pseudocyst, and then by distal pancreatectomy when its true nature was revealed. We conclude that every effort should be exerted to distinguish between pancreatic pseudocysts and cystic tumors of the pancreas to avoid the serious misjudgement of draining rather than extirpating a pancreatic cystic tumor. Additionally, percutaneous drainage of a pancreatic pseudocyst is a useful adjunct that may substitute for surgical drainage.
