Thoracic foreign body management after penetrating chest trauma by chainsaw in the Amazon countryside: A case report.

Introduction: Accidents involving chainsaws are not uncommon in trauma care and may present as penetrating injuries with retention of a foreign object in the patient's chest. The current literature, however, does not present a consensus on the best way to approach these cases.

Presentation Of Case: Male patient, 46-year-old man, born in Amazonas countryside, brought to the city of Manaus with a penetrating injury resulting from an accident with a chainsaw and retaining a 2cm sawtooth in his chest, six days after the event.

Left-sided gallbladder (LSG) associated with true diverticulum, a case report.

The left-sided gallbladder (LSG) is a rare type of anatomical variation (ectopia) defined by the location of the bladder to the left side of the liver falciform and round ligaments. Initially reported in 1886 by Hochstetter, the finding is usually accidental since it is mostly an asymptomatic condition, thus not causing the patient any harm and being few reported cases in the current literature. Surgical cases are most associated with gallstones such as presented in this case report.

Neuroendocrine pancreatic tumor causing chronic diarrhea in young adult, a case report.

Secretory tumors of vasoactive intestinal polypeptides (VIPomas) are rare neuroendocrine pancreatic neoplasms usually associated with secretory diarrhea. Most cases present themselves with diarrhea, weight loss, and hypokalemia. Although VIPoma patients share easily distinguishable symptoms, early diagnosis remains a challenge.

Bowel obstruction in entero-colic fistula associated with magnet ingestion in children at the Amazonas countryside.

Ingestion of small objects by children became worrisome as the number of cases increased over the years. Consequences such as intestinal obstruction or even infection of the gastrointestinal tract are becoming more frequent since even in majority cases there is having only an expectant conduct, complications can occur. Also, the combination of two elements such as punctiform metallic materials and imams cause fistula formation in loops with greater ease, granulomas in the intestines, perforation, and can progress to peritonitis or abscesses, as well as having considerable morbidity.

The structure of the agaran sulfate from Acanthophora spicifera (Rhodomelaceae, Ceramiales) and its antiviral activity. Relation between structure and antiviral activity in agarans.

The sulfated agaran isolated by water extraction from the red seaweed, Acanthophora spicifera (Rhodomelaceae, Ceramiales), is made up of A-units highly substituted with sulfate groups on C-2 (28-30%), sulfates on C-2 and 4,6-O-(1'-carboxyethylidene) groups (9-15%), and only the C-2 sulfate groups (5-8%) with small amounts of C-6 sulfate, 6-O-methyl, and nonsubstituted residues. B-units are formed mainly by 3,6-anhydro-alpha-L-galactose (15-16%) and its precursor, alpha-L-galactose 6-sulfate (10-17%), together with lesser amounts of 3,6-anhydro-alpha-L-galactose 2-sulfate, alpha-L-galactose 2,6-disulfate, alpha-L-galactose 2,3,6-tri-sulfate, alpha-L-galactose 2,6-disulfate 3-xylose, 2-O-methyl-alpha-L-galactose, and unsubstituted alpha-L-galactose. Small, but significant quantities of beta-D-xylose were found in all the fractions, together with small amounts to traces of D-glucose.
