Diverticulum of the cecum is a rare, benign, generally asymptomatic lesion that manifests itself only following inflammatory or hemorrhagic complications. Most patients with inflammation of a solitary diverticulum of the cecum present with abdominal pain that is indistinguishable from acute appendicitis. The optimal management of this condition is still controversial, ranging from conservative antibiotic treatment to aggressive resection. We describe four cases that presented with symptoms suggestive of appendicitis, but were found at operation to have an inflamed solitary diverticulum.

Background: The splenic cysts constitute a very rare clinical entity. They may occur secondary to trauma or even being more seldom due to parasitic infestations, mainly caused by ecchinocccus granulosus. Literature lacks a defined concencus including the treatment plans and follow up strategies, nor long term results of the patients. In the current study, we aimed to evaluate the diagnosis, management of patients with parasitic and non-parasitic splenic cysts together with their long term follow up progresses.

PURPOSE:To study the effects of progesterone on an experimental colitis model. METHODS:Wistar albino rats were treated subcutaneously with 2mg/kg once a day during seven days Colitis was induced by intrarectal administration of 5mg trinitrobenzene sulfonic acid (TNBS). Disease activities, macroscopic and microscopic scores were evaluated.To determine the response provoked by progesterone we measured Colonic malondialdehyde (MDA), TNF alfa, IL-6 and Nitric oxide (NO) levels in addition to the MPO (Myeloperoxidase) and caspase-3 activities. RESULTS:Progesterone ameliorated significantly the macroscopic and microscopic scores. TNBS-induced colitis significantly increased the colonic MDA levels and caspase-3 activities in group 2 in comparison to the control group. The results of the study revealed a decline in MDA, NO, IL6 and TNF-α levels in the colon tissue and in blood due to progesterone therapy in group 3 when compared to the group 2, a significant improvement. Progesterone treatment was associated with decreased MDA, MPO, TNF alfa and caspase-3 activity. CONCLUSION:Progesterone therapy decreased oxidative damage in the colonic mucosa.Key words: Progesterone. Colitis. Inflammation. Colon. Rats. RESUMO OBJETIVO:Investigar os efeitos da progesterona em um modelo de colite experimental. MÉTODOS:Ratos albinos Wistar foram tratados subcutaneamente com 2mg/kg por dia durante sete dias. A colite foi induzida por administração intrarretal de 5mg ácido sulfônico trinitrobenzeno (TNBS). Foram avaliadas as atividades da doença, escores macroscópicos e microscópicos Para determinar a resposta provocada pela progesterona foi medida no cólon os níveis de malondialdeído (MDA), TNF alfa, IL-6 e óxido nítrico (NO), além da atividade da MPO (Myeloperoxidase) e caspase-3. RESULTADOS:A progesterone melhorou significantemente os escores macroscópicos e microscópicos. A colite induzida pelo TNBS significantemente aumentou os níveis colônicos de MDA e a atividade da caspase-3 no grupo 2 em comparação com o grupo controle.Os resultados do estudo revelaram um declínio nos níveis de MDA, NO, IL6 e TNF-α no tecido colônico e no sangue devido à terapia com a progesterona no grupo 3 quando comparado ao grupo 2. O tratamento com a progesterona foi associado com decréscimo do MDA, MPO, TNF alfa e atividade da caspase-3. CONCLUSÃO:A terapia com progesterona decresce o dano oxidativo na mucosa do cólon.Descritores: Progesterona. Colite. Inflamação. Colo. Ratos.Karatepe O et al.

In conclusion we recommend preperitoneal repair in strangulated hernia instead of Lichtenstein repair. The use of preperitoneal hernia repair for strangulated inguinal hernia is safe, and any need for laparatomy if bowel resection is necessary.
