Expression of cyclooxygenase-2 and its relation to histological grade, inducible nitric oxide synthase, matrix metalloproteinase-2, CD-34, Caspase-3, and CD8 in invasive ductal carcinoma of the breast

To assess by immunohistochemistry the cyclooxygenase-2 [COX-2] expression in invasive ductal carcinoma and its possible correlation with the histological grade, inducible nitric oxide synthase [iNOS], matrix metalloproteinase-2 [MMP2], and other common immunohistochemical parameters [CD-34, Caspase-3, and CD8]. This was a retrospective pathology archive study including 50 female patients and was performed in Mustafa Kemal University, Hatay, and Sutcu Imam University, Kahraman Maras, Turkey. The routine hematoxylin-eosin staining and COX-2, iNOS, MMP-2, CD-34, CASP-3, and CD8 immunoperoxidase techniques were performed on paraffin-embedded tissues. The mean value of COX-2 was 274.02 +/- 54.49 and MMP-2 was 263.42 +/- 54.30, whereas the mean iNOS values were 258.10 +/- 56.05. CD-34 staining also yielded positive results as 26.18 +/- 8.00. The mean value of CASP-3 was 284.06 +/- 41.2 and CD8 was 164.17 +/- 69.5. This reveals an inverse correlation between CASP-S reactivity and CD8 [Spearman correlation [r]= -0.33, p=0.01]. There was also an inverse correlation between iNOS reactivity and patients age [r = -0.29, p=0.013]. There was a positive correlation with COX-2 and MMP-2 [p=0.00], but there was no relation with COX-2 and other parameters. COX-2 expression is an important parameter for invasive ductal carcinoma of the breast. We found a positive correlation between COX-2 and MMP-2, whereas, we could not show direct correlation between COX-2 and iNOS, CD-34, CASP-3, and CD8

Hydatid Disease Involving Some Rare Locations in the Body: a Pictorial Essay

Hydatid disease (HD) is an endemic illness in many countries, and it poses an important public health problem that's influenced by peoples' socioeconomic status and migration that spreads this disease. Although rare, it may occur in any organ or tissue. The most common site is the liver (59-75%), followed in frequency by lung (27%), kidney (3%), bone (1-4%) and brain (1-2%). Other sites such as the heart, spleen, pancreas and muscles are very rarely affected. Unusual sites for this disease can cause diagnostic problems. This pictorial essay illustrates various radiological findings of HD in the liver, spleen, kidney, pancreas, peritoneal cavity, omentum, adrenal, ovary, lung, mediastinum and retroperitoneum. Familiarity with the imaging findings of HD may be helpful in making an accurate diagnosis and preventing potential complications.

Fatal congenital cytomegalovirus infection following recurrent maternal infection after a 7-year interval

It is generally accepted that the risk for fetal infection is greatest with maternal primary cytomegalovirus CMV infection and much less likely with recurrent infection. Here, we report a fatal case of congenital CMV infection following recurrent maternal infection after a 7-year interval. A 3-month-old female baby presented with fever, jaundice, vomiting and stopping breast-feeding. Physical examination revealed mild respiratory distress, hepatosplenomegaly, microcephaly and growth retardation. Laboratory examination included bilirubin concentrations Total: 7.17 mg/dl; conjugated 6.67 mg/dl, aspartate transaminase 141 IU, and alanine transaminase 499 IU. Enzyme-linked immunosorbent assay test results revealed + CMV IgM and + CMV IgG. She died on the 10th day of admission with the diagnosis of CMV hepatitis, pneumonia, and multi-organ failure. Nuclear and cytoplasmic inclusions were demonstrated in the lung, liver and brain on postmortem biopsy. This case highlights that the outcome of babies born to mothers with recurrent maternal CMV infection may be more severe and fatal than previously thought
