The main aim of the study was to evaluate the potential roles of KRAS/NRAS proto-oncogenes, IL-4 VNTR variants and HPV prevalence in colorectal cancer metastasis. As the second aim, the interactions of the analyzed genes and viral sequences with both clinicopathological variables and each other were targeted. ⋯ Our study comprehensively and concomitantly evaluated several potential molecular risk factors. Future studies designed in such combined approaches will substantially contribute to better manage colorectal cancer tumorigenesis from molecular biological perspective (Tab. 6, Fig. 2, Ref. 40).

The aim of this retrospective study was to evaluate results of four different surgical approaches to palatoplasty and to demonstrate which type showed the lowest number of cases with the need for secondary surgeries. The results of 227 patients who underwent cleft palate surgical repair over a 13-year period (2000-2012) were included. The incidence rates of oronasal fistula, velopharyngeal insufficiency with the need of pharyngeal flap and pharyngoplasty were examined. ⋯ Neither there was observed a significant difference in the incidence of additional surgery between male and female patients. However, a higher need for pharyngeal flap was noted in the female group (Tab. 8, Ref. 38). Keywords: complications after palatoplasty, cleft repair techniques, Pierre Robin sequence, pharyngeal flap.

Case Reports
Early recurrence of focal segmental glomerulosclerosis as an unusual cause of primary kidney transplant malfunction.
Recurrence of the primary disease is one of the most common causes of graft failure in the first decade after kidney transplantation. We present a case of a patient with an unusually rapid recurrence of focal segmental glomerulonephritis in the graft, the recognition of its occurrence was hampered by the primary graft affection and oligoanuria and by insignificant histological changes in the first two biopsy samples in the early post-transplant period, as well as by unawareness of the disease leading to terminal renal failure, as no renal biopsy was performed due to grade 3 obesity. Only worsening of hypoalbuminemia and finding of massive proteinuria despite oligoanuria were crucial for further management. ⋯ However, complex targeted therapy did not result in restoration of graft function and decrease in proteinuria. This case history was aimed to draw attention to the knowledge of the importance of the primary disease confirmed by renal biopsy and early (so called pre-emptive) treatment in case of diseases with a high potential of recurrence (Fig. 7, Ref. 10).

Glioblastoma (GB) is the most common and biologically the most aggressive primary brain tumor of the central nervous system (CNS) in adults. Standard treatment for newly diagnosed GB consists of surgical resection, radiotherapy, and chemotherapy with temozolomide (TMZ). Despite numbers of studies, a resistance to chemotherapy is the major obstacle to successful GB treatment. ⋯ Identification of apoptotic gene panel in T98G cell line could help to improve understanding of brain tumor cells metabolism. Recognizing of the pro-apoptotic and anti-apoptotic genes expression changes could contribute to clarify the sensitivity to TMZ therapy and molecular base in healthy and tumor cells (Tab. 1, Fig. 2, Ref. 48).

Coronary slow flow (CSF) is determined by delayed opacification of the epicardial coronary arteries without obstructive disease. The triglyceride glucose index (TGI) has been suggested as a useful marker of insulin resistance. Previous studies have shown that TGI is associated with cardiovascular disease, but no study has examined the relationship between TGI and CSF. ⋯ TGI was statistically significantly higher in the CSF group than the control group. According to the multivariate logistic regression analysis, only TGI was independently associated with the risk of CSF, but higher TGI did not predict more slow coronary flow. Prospective studies are needed to clarify the prognostic relationship of TGI and CSF in terms of future cardiovascular events (Tab. 2, Fig. 1, Ref. 19).
