RESUMEN

Background: Adipose tissue is a dynamic endocrine organ, a highly active metabolic tissue, and an important source of cytokines. Inflammatory factors play an important role in visceral obesity associated with insulin resistance (IR), metabolic syndrome (MS), hypertension, non-alcoholic fatty liver disease (NAFLD), diabetes mellitus type 2 (DM2), endothelial dysfunction (ED) and atherosclerosis. Objectives: To examine corelation of siMS score, as a quantification method for metabolic syndrome (MS), with insulin resistance, glucoregulation parameters, as with other co-founding factors of MS, inflammation and thrombosis factors, microalbuminuria, uric acid, fatty liver index (FLI) and homocysteine. Methods: The study included 451 obese individuals with pre-metabolic syndrome (pre-MS) and MS (age 16-75, body mass index (BMI) > 25kg/m2) classified into two groups: I-age 10-30 (167 patients); II-age 31-75 (284 patients). International Diabetes Federation (IDF) classification was applied for diagnosing metabolic syndrome. Patients with less than three criteria indicated below were considered pre-metabolic syndrome. siMS risk score was used. Results: siMS score increased with age: I-3.03 ± 0.87, II-3.27 ± 0.90. siMS score correlated with associated factors of MS: hyperinsulinemia and IR, ALT, gama-GT, FLI, uric acid in both groups and CRP (p < 0.01) in group I. Correlations in II group: siMS score with PAI-1 (p = 0.01), microalbuminuria (p = 0.006), homocysteine ​​(p = 0.076). Conclusion: Correlation of siMS score with HOMA-IR confirmed that hyperinsulinism and insulin resistance are in the basis of MS. Correlation of siMS score with parameters of NAFLD, CRP, PAI-1, uric acid, microalbuminuria and homocysteine indicates that they are significant co-founding factors of MS. Correlation of siMS score with PAI-1, microalbuminuria, homocysteine, indicates higher risk for progression of endothelial dysfunction and atherosclerosis with age.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: Nucleotide-binding oligomerization domain (NOD) 1 and NOD 2 are members of the NOD-like receptor (NLR) family and contain a caspase recruitment domain. NLRs are located in the cytosol, bind bacterial and viral ligands and play a key role in the realization of innate and adaptive immune response, inflammation, apoptosis and reactive oxygen species generation. Insulin resistance (IR) is a leading cause of type 2 diabetes mellitus (T2DM) and associated with obesity, inflammation and pro-inflammatory responses. NOD1 and NOD2 gene variants may affect the risk of chronic inflammation, insulin resistance and T2DM by shifting the balance between pro- and anti-inflammatory cytokines. The aim of our study was to determine whether the NOD1/2 gene variants might contribute to the risk of T2DM and IR. METHODS: The rs5743336 variant of NOD1 and rs2066847 variant of NOD2 were analysed by PCR-RFLP analysis in 200 subjects (T2DM: n = 100; healthy controls: n = 100) of Turkish origin. PCR products were digested with the AvaI and ApaI restriction enzymes. For the NOD1 site, the presence of the G allele was indicated by cleavage of the 379 bp amplified PCR product that yielded 209-bp and 170-bp fragments. For the NOD2 site, 151-bp PCR products were cleaved and yielded 130-bp and 21-bp fragments when the WT-insC mutation was present. Comparisons of the genotypes between controls and patients were performed by chi-square tests. RESULTS AND DISCUSSION: The genotypes of the rs5743336 variant of NOD1 and the rs2066847 variant of NOD2 are presented, and no significant differences were observed in the genotype frequencies of the NOD1 and NOD2 variants between the healthy controls and T2DM patients (P > 0·05). According to our preliminary data, NOD1/2 gene variants are not linked with T2DM and IR. WHAT IS NEW AND CONCLUSION: This study is the first to look for possible association of the genotype frequencies of NOD1 and NOD2 genes with T2DM and IR. The significant finding of this report is that the rs5743336 and rs2066847 variations in the NOD1/2 gene are not associated with T2DM and IR risk in patients of Turkish origin.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: Inhibition of the fibrinolytic system may occur at the level of plasminogen activation, mainly by PAI-1. Mental and physical stress caused to alterations of platelet function, and also decreased to fibrinolytic activity. Furthermore, stress-induced thrombosis regulation was proposed to be by PAI-1 in schizophrenia patients. In this study, the distribution of genotypes and frequency of alleles of the plasminogen activator inhibitor type 1 (PAI-1) gene 4G/5G polymorphism in different Turkish clinical schizophrenia subtypes was investigated for its role in schizophrenia development. METHODS: The clinical schizophrenia subtypes include paranoid, catatonic, disorganized, undifferentiated and residual, as diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition IV (DSM-IV). Samples of genomic DNA (250 total, including 150 schizophrenia patients and 100 healthy subjects) were analysed. PAI-1 4G/5G genotyping was performed by polymerase chain reaction-allele-specific amplification. PCR products were separated by 2% agarose gel electrophoresis and then visualized. RESULTS AND DISCUSSION: The genotype distributions (P = 0·136) and allele frequencies (P = 0·721 for 4G, P = 0. 097 for 5G) were not significantly different between patients with schizophrenia and control subjects for the 4G/5G polymorphism. Similar results were also found for the genotype distributions (P = 0·640) and allele frequencies (P = 0·763 for 4G, P = 0·448 for 5G) in the clinical schizophrenia subtypes compared to the each other. WHAT IS NEW AND CONCLUSION: We conclude that PAI-1 4G/5G polymorphism was not significantly associated with schizophrenia or its subtypes in the Turkish population. However, we recognize that with our sample sizes, we cannot exclude weak associations.

RESUMEN

Human serum paraoxonase 1 (PON1) is carried by high-density lipoprotein in blood circulation and is shown to be effective in preventing oxidized phospholipids carried by low-density lipoprotein particles, thus it acts as an antioxidant. Polymorphism in this gene has been investigated for many metabolic diseases, but it is not thought to be a genetic risk factor for essential hypertension. The aim of this study was to determine whether there was an association between PON1 gene polymorphisms and concentration with essential hypertension. The study population was comprised of 100 patients with essential hypertension and 100 healthy controls. One promoter region [C(-108)T] and two coding region (Q192R and L55M) polymorphisms in the PON1 gene were genotyped in individuals by using the TaqMan assay. Plasma PON1 concentration in all volunteers was also measured spectrophotometrically by the enzyme-linked immunosorbent assay method. The genotype and allele frequencies of the PON1 C(-108)T polymorphism showed significant differences between the essential hypertensive and control groups (CT vs. CC: p<0.001; T allele vs. C allele: p<0.001). There was no significant difference for the PON1 L55M polymorphism between the groups, while the heterozygote genotype of the PON1 Q192R polymorphism showed significant difference (p = 0.03). The PON1 concentration was also found to be significantly lower in hypertensive patients (p < 0.001). Decline in the level of PON1 gene may be one of the main factors in the development of essential hypertension, and the PON1 C(-108)T polymorphism may have a prognostic value in the patients with essential hypertension.

RESUMEN

BACKGROUND: Acute appendicitis is the most common cause of acute abdomen. Carcinoid tumor of the appendix is a rare incidental finding that can present with the clinical picture of acute appendicitis. CASE REPORT: During open surgery for acute appendicitis, a 3 cm solid mass, not noticed externally, was palpated at the base of the appendix. The mass and the appendix were excised by en-bloc wedge resection. The histopathological examination of the lesion revealed carcinoid tumor. CONCLUSION: The aim of this presentation is to remind that neoplasms of the appendix may, although rarely, present the clinical picture of acute appendicitis, and to highlight that they, particularly those located at the base of the appendix and in cecum, may be overlooked during laparoscopy. The importance of preoperative computerized tomography ins uch cases has to be underlined.

RESUMEN

Diabetes mellitus (DM) is one of the most common diseases worldwide, and is a significant risk factor for healthcare-associated infections (HAIs). Our aim in this study was to compare the distributions of HAIs and the causative pathogens between diabetic and non-diabetic patients. In this study, 716 HAIs in 465 diabetic patients and 761 HAIs in 465 non-diabetic patients were evaluated. HAIs in patients with DM were most frequently urinary tract infections (UTIs) [266 infections (37.2 %)], followed by blood stream infections (BSIs) [161 infections (22.5 %)], surgical site infections (SSIs) [127 infections (17.7 %)], pneumonia [107 infections (14.9 %)] and any other infections [161 infections (22.5 %)]. The rates of UTIs, BSIs, SSIs, pneumonia and any other infections were similar between diabetic and non-diabetic patients. In terms of the causative pathogens, Staphylococcus aureus more frequently caused SSIs and Candida spp more frequently caused UTIs in diabetic patients compared with non-diabetic patients. We found no differences in the distribution of HAIs between patients without and with DM. However, S. aureus and Candida spp were more common causative pathogens of SSIs and URTIs, respectively, in diabetic patients than in non-diabetic patients.

RESUMEN

OBJECTIVE: To evaluate the relationship between urogenital symptoms and climacteric complaints, including anxiety, depression, somatic, vasomotor and sexual subscores according to the Greene Climacteric Scale (GCS). METHODS: We retrospectively reviewed the records of 1278 patients and the 908 patients who fulfilled the inclusion criteria were included in the study. The relationships were evaluated between GCS and vaginal symptoms, including vaginal pain, dyspareunia, itching, discharge, burning, dryness, and postcoital bleeding, and urinary symptoms, including dysuria, frequency, nocturia and incontinence, by using univariate and multivariate analyses. RESULTS: Among vaginal symptoms, somatic and sexual scores and, among urinary symptoms, anxiety and somatic scores were found to be the most associated factors. Of the vaginal symptoms, the highest odds ratios for somatic score and sexual score were found to be 2.21 (95% confidence interval (CI) 1.69-2.88, p < 0.001) and 2.08 (95% CI 1.70-2.56, p = 0.029), respectively. Multivariate logistic regression analyses for urinary symptoms revealed that the highest odds ratios for anxiety, somatic, depression and sexual scores were 1.53 (95% CI 1.20-1.95, p = 0.001), 1.92 (95% CI 1.38-2.66, p = 0.01), 1.47 (95% CI 1.11-1.94, p = 0.007), and 1.28 (95% CI 1.06-1.55, p < 0.001), respectively. CONCLUSIONS: There is a strong relationship between urogenital symptoms and GCS subscores. Therefore, clinicians should be aware of urogenital problems in the presence of severe climacteric symptoms and this may provide earlier treatment for urogenital complaints.

RESUMEN

PURPOSE: To predict the invasiveness of urothelial bladder carcinoma using a logistic regression model on preoperative peripheral blood samples. PATIENTS AND METHODS: Hospital data of patients operated for urothelial carcinoma were reviewed retrospectively. Preoperative blood samples were collected before the first cystoscopic examination. Any kind of infection or inflammation was an exclusion criterion. Patients were grouped as having a non-muscle-invasive or muscle-invasive urothelial carcinoma. The mean age was 69 years and was determined as the cut-off value. According to receiver operating characteristic curves, threshold points were determined for lymphocytes, neutrophil count, neutrophil-to-lymphocyte ratio (NLR), thrombocytes and mean platelet volume. Demographic specialties, parameters obtained from blood samples, tumor size and multiplicity were evaluated and significant parameters were put into a logistic regression model. RESULTS: The study group consisted of 80 non-muscle-invasive and 102 muscle-invasive patients. Age (≤69 vs. >69), female gender, NLR (2.57), mean platelet volume (7.9/fl) and platelet count (400,000/µl) were significant parameters and put in a model. Using odds ratios, the probability of tumor invasiveness was calculated by a formula. CONCLUSION: Age, female gender, NLR and platelet count were found to be the predictors of invasiveness of urothelial carcinoma.

RESUMEN

Acute coronary syndrome (ACS) is the main cause of mortality in diabetics. Acute myocardial infarction (AMI) in diabetics is much more often than in non-diabetics. MMP-9 activity could ease the formation of atherosclerosis, destabilization and plaque rupture as well as thrombocyte aggregation. THE AIM OF THIS STUDY IS TO EXAMINE: MMP-9 defining in serum in diabetics; the impact of diabetes mellitus on atherosclerosis and MMP-9 level; relation between serum values of MMP-9 and markers of glycoregulation and lipid status, respectively. RESULTS: The greatest concentration of both total and active MMP-9 serum has been noted in diabetics group with ACS. Both total and active MMP-9 values, in group with diabetes and ACS showed significantly important difference regarding the values in control group. Total and active MMP-9 showed statistically important correlation between the values of glycated hemoglobine A1c (HbA1c) and inverse correlations with values of subfraction HDL3.Active MMP-9 showed statistically important inverse correlation with value of HDL cholesterol. IN CONCLUSION: According to the results, it has been thought that active MMP-9 shows a certain degree of atherosclerotic changes on blood vessels better than total MMP-9. MMP-9, active one, could present an early marker of atherosclerosis, especially on coronary blood vessels, in diabetics with type 2.

RESUMEN

UNLABELLED: In this study, ERα gene PvuII and XbaI polymorphisms and COL1A1 gene Sp1 polymorphisms in postmenopausal women were compared with lumbar vertebra and femoral neck BMD values. In conclusion, it was designated that PvuII polymorphism was effective on average lumbar vertebra BMD value in postmenopausal women of our study group. INTRODUCTION: Bone mineral density (BMD), the major determinant of osteoporotic fracture risk, has a strong genetic component. Several candidate gene polymorphisms have been implicated in the regulation of this process. In this study, the relationship among BMD values of lumbar vertebra and femoral neck and ERα gene PvuII and XbaI polymorphisms and COL1A1 gene Sp1 polymorphism in 126 postmenopausal women (30 normal, 46 osteopenic, and 50 osteoporotic in terms of bone mineral density) was researched. METHODS: The ERα gene PvuII and XbaI genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) whereas the COL1A1 gene Sp1 genotype was determined by real-time PCR. BMDs at the lumbar spine (vertebrae L1-L4) and hip (femur neck) were measured by dual-energy X-ray absorptiometry. RESULTS: According to our study results, the significant difference was found in women with normal, osteopenic, and osteoporotic bone mass in terms of ERα gene PvuII polymorphism "pp" genotype frequency. The "pp" genotype frequency was significantly lower in women with normal bone mass. Average lumbar vertebra BMD value of women with "PP" genotype was significantly higher than that with "pp" genotype. On the other hand, in the evaluations on ERα gene XbaI polymorphism and COL1A1 gene Sp1 polymorphism, it was noted that there was no difference in terms of average BMD values, genotype, and allele frequencies among groups. CONCLUSION: In conclusion, it was designated that ERα gene PvuII polymorphism was effective on average lumbar vertebra BMD value in postmenopausal women of our study group.

RESUMEN

PURPOSE OF INVESTIGATION: The aim of the study was to show the role of the cytoskeletal proteins CK8 and CK18 in endometrial cancer invasion and to histopathologically classify endometrial cancer patients. METHODS: This study was a prospective analysis of 49 histologic samples of consecutively surgically operated endometrial cancer patients. After histopathologic classification the most invasive tumor area was selected for immunohistochemistry. Monoclonal antihuman keratin Ab-4 and keratin Ab-1 were applied. RESULTS: CK8 and CK18 stained tumoral tissue and tumoral cell debris in the lymphovascular space were significantly correlated with stage (p < or = 0.005). CONCLUSIONS: To understand the causes of early treatment failure in endometrial cancer patients, further studies are needed to show the role of enhancing factors of endometrial cancer invasion.

RESUMEN

The morphometric and karyological analyses of 52 specimens belonging to the two subspecies of Nannospalax leucodon were examined from 14 localities in Turkey. Five karyotypic forms were recorded (2n = 60, the total numbers of chromosomal arms (NF) = 74, the numbers of autosomal arms (NFa) = 70; 2n = 60, NF = 76, NFa = 72; 2n = 60, NF = 82, NFa = 78; 2n = 56, NF = 72, NFa = 68; 2n = 38, NF = 74, NFa = 70). The morphological features of two subspecies were studied using both numerical taxonomy and traditional methods. Thirty skull measurements and four baculum measurements were subjected to discriminant function analysis to find morphometric criteria allowing subspecies identification. Two subspecies were clearly separated from each other by macroanatomical characterictics and numeric characteristics. The first upper molar has four alveoli cubicles in young specimens of Nannospalax leucodon anatolicus, while M(1) has 1 cubicle in Nannospalax leucodon cilicicus. In the western subspecies (N. l. anatolicus, 2n = 38), urethra openness is surrounded by three lobes. However, in the eastern subspecies (N. l. cilicicus, 2n = 60), there are two lateral lobes.

RESUMEN

PURPOSE OF INVESTIGATION: Actin bundling protein fascin has been previously associated with tumor progression in human cancers. We evaluated whether fascin also plays a role in endometrioid carcinomas. METHODS: Cases of 28 proliferative and hyperplastic endometrium and 43 endometrioid carcinomas were examined by immunohistochemistry using antihuman fascin antibody. RESULTS: Weak fascin expression in glandular epithelium was observed in 39% of non-neoplastic samples and various degrees of fascin expression were observed in 74% of neoplastic samples. The number of positively stained samples and intensity of epithelial staining were significantly higher in endometrioid carcinoma compared to the non-neoplastic group (p < 0.001). The number of positively stained samples and total fascin scores of stroma were significantly higher in proliferative and hyperplastic endometrium biopsies compared to the endometrioid carcinoma (p < 0.001). Higher grade endometrioid carcinoma cases had significantly increased total epithelial fascin scores (.042, p < 0.05). There was also a significant difference between tumor grade and patient survival (.040, p < 0.05). There was a significant correlation between microvessel count and disease-free survival (r = .412, p = .006). In the proliferative and hyperplastic endometrial biopsies microvessels stained homogeneously in all cases (28/28), but in the endometrioid carcinoma group eight out of 43 cases showed heterogeneous fascin staining of microvessels. The difference was significant (.019, p < 0.05). CONCLUSIONS: Our study supported the dynamic role of actin bundling protein fascin in generating and maintaining endometrial neoplasms. It also showed that in the development of neoplasia, stromal fascin expression decreases but epithelial fascin expression up-regulates.

RESUMEN

PURPOSE OF INVESTIGATION: The aim of the study was to compare the fascin expression pattern and histopathologic features of malign epithelial ovarian tumors obtained by the primary and secondary surgeries. METHODS: The samples of 94 epithelial ovarian carcinomas, 35 secondary surgeries for ovarian carcinomas, 13 borderline epithelial ovarian tumors, 25 cystadenomas and four normal ovarian tissues were stained by means of fascin immunohistochemistry. Secondary surgeries included in the study were secondary cytoreduction at the time of second-look laparotomy (SLL), interval debulking surgery after neoadjuvant chemotherapy or secondary cytoreductive surgery in patients with recurrent epithelial ovarian carcinoma. RESULTS: Mean rank value of the stromal fascin score was higher in 94 cases of malign epithelial ovarian carcinomas than borderline epithelial tumors, cystadenomas and normal ovaries (.000, p < 0.001). There was no significant difference in terms of total epithelial fascin score (.685, p > 0.05) and total stromal fascin score (.572, p > 0.05) between the primary and the secondary surgeries of epithelial ovarian carcinomas. CONCLUSIONS: Regarding the results of stromal fascin expression in 94 epithelial ovarian carcinomas, we hypothesized that cell-matrix interaction was an important step in the progression of malign epithelial ovarian neoplasms. Our study showed that the initial tumorigenic phenotype did not change with time and use of cisplatinum-based combination chemotherapy. Further studies with close follow-up of patients are necessary to reveal the role of fascin on matrix degradation mechanisms which might be the cause of the recurrences in ovarian neoplasms.

RESUMEN

PURPOSE OF INVESTIGATION: The aim of the study was to investigate the role of fascin in tumor progression and to investigate the role of fascin on endothelial cell migration and angiogenesis in ovarian neoplasms. METHODS: In the study, 94 malign epithelial ovarian neoplasms, 13 borderline epithelial ovarian neoplasms, 25 serous and mucinous cystadenomas and four normal ovarian tissues were examined by means of immunohistochemistry, using monoclonal antihuman fascin antibody, clone IM20. RESULTS: Total stromal fascin score in cases of borderline and malign epithelial ovarian tumors was significantly higher compared to normal ovaries and benign epithelial ovarian tumors (.000, p < 0.001). There was no statistically significant difference in terms of total epithelial fascin scores of samples between groups (.080, p > 0.05). Presence of vascular invasion (.000, p < 0.001), psammomatous calcifications (.001, p = 0.001), and lymphocytic infiltration (.000, p < 0.001) were significantly higher in malign neoplasms. There was no significant difference in terms of mean microvessel count and homogeneous or heterogeneous fascin expression of microvessels between the benign and malign groups (respectively p = .228 and p = .143). CONCLUSIONS: This study suggests that up-regulation of fascin in tumoral tissue may promote invasion of ovarian carcinoma by cell-matrix adhesion.

RESUMEN

BACKGROUND: Tumour angiogenesis is essential for the growth, invasion and metastasis of solid tumours. There are several lines of evidence that the mast cells play an important role in tumour angiogenesis. AIMS: The study focused to determine the correlation between the microvessel and mast cell densities, and to evaluate whether tumour angiogenesis and mast cell density could predict recurrence following curative surgery in patients with colorectal carcinomas. PATIENTS: Microvessel and mast cell densities were investigated in tumour specimens from 60 patients with colorectal carcinoma. METHODS: Microvessels were stained by immunohistochemical method using a monoclonal antibody anti-CD34. The routine Giemsa blue staining method was used to assess the mast cells. Microvessels and mast cells were counted in a x400 field. RESULTS: The mean microvessel and mast cell counts were higher in patients with recurrence compared with those patients who were disease-free for at least 24 months (p<0.001). The Spearman's correlation coefficient revealed a significant correlation between mast cell and microvessel counts in colorectal carcinomas (r=0.684; p<0.001). Kaplan-Meier plots of survival showed that the high microvessel (>28) and mast cell (>6) counts correlated with a shorter disease-free survival (p=0.0003 and p=0.0013, respectively). Multivariate analysis showed that the depth of penetration (T4 versus T2) (p=0.004), liver metastasis (p=0.04) and microvessel density (p=0.003) were independent predictors of recurrence. In multivariate analysis, mast cell density did not reach significance. CONCLUSIONS: Our results suggest that the microvessel density of the primary tumour may be an important independent predictor of tumour recurrence and time to recurrence in colorectal carcinomas. The significant correlation between mast cell and microvessel counts suggest that the mast cells may have a role in tumour progression via promoting angiogenesis.

RESUMEN

PURPOSE OF INVESTIGATION: Our objectives were (1) to examine expression of fascin in cervical tissues with chronic inflammation, intraepithelial neoplasms and invasive carcinomas, and (2) to investigate the role of fascin on endothelial migration and angiogenesis in cervical neoplasms. METHODS: In this study we investigated by means of immunohistochemistry fascin expression in 92 cervical biopsy samples representative of chronic inflammation (n=13), squamous intraepithelial lesions (SILs, n = 33) and invasive carcinomas (n = 46). RESULTS: Various degrees of fascin expression were observed in 94% of the samples of SILs, in 67% of the samples of invasive cervical carcinoma and in 69% of the samples of chronic inflammation. Total epithelial fascin scores of samples were significantly higher in high-grade (H)SILs compared to low-grade (L)SILs, invasive carcinoma and chronic inflammation of the cervix (p < 0.05). Mean microvessel count was 55.00 +/- 5.17 in HSILs, 40.76 +/- 3.57 in LSILs, 37.11 +/- 2.91 in carcinoma and 25.69 +/- 3.98 in chronic inflammation. We found a significantly higher microvessel count in HSILs compared to invasive carcinoma and chronic inflammation (respectively, p = .004, p = .000). CONCLUSION: Epithelial fascin expression up-regulated when the malignant tumor cell phenotype had occurred in the cervix. Similarly, microvessel count increased with the beginning of cervical tumorigenesis.

RESUMEN

It is well established that a condition of hypercoagulation due to deficiencies of antithrombin III, protein C and protein S may result in thrombo-embolism. To evaluate the possibility of hypercoagulation in acute mesenteric ischemia (AMI); clinical features, ECG changes, drug history, the length of intestine remaining after the resection and mortality of 15 consecutive patients were recorded and plasma levels of antithrombin III, Protein C and protein S were measured. Antihypertensive, antidiabetic and digitalis were the main drugs used by the patients. Atrial fibrillation was the main ECG finding (60%). AMI was attributed to thrombo-embolic phenomena because of atrial fibrillation in these patients. Levels of antithrombin III and protein S were lower in patients without atrial fibrillation compared to those with the condition (mean values 16.18 vs. 18.04 and 87.33 vs. 94.22 respectively) but the difference was not statistically significant. Levels of Protein C were lower and the length of intestine remaining after resection was shorter in patients without, compared to those with, atrial fibrillation (mean values 77.00 vs. 88.66, and 52.5 cm vs. 86.11 cm respectively). The difference was statistically significant (p < 0.05). Postoperative mortality rate was 33.3% (5 patients) and the length of intestine remaining after resection was the main determining factor in the prognosis of the patients. We conclude that a condition of hypercoagulation due to a deficiency of protein C has a significant role in the pathogenesis of AMI especially in patients without atrial fibrillation.

RESUMEN

The treatment techniques for pilonidal disease are either associated with high recurrence rates or complex procedures. This prospective randomized study compared the outcome of excision and marsupialization technique with sinus excision technique. A total of 40 consecutive patients with limited, chronic pilonidal sinus disease were operated with either excision and marsupialization technique (Group 1, n=20) or sinus excision technique (Group 2, n=20). The demographics, perioperative data, complications and recurrences were recorded. Patient satisfaction was evaluated with a specific questionnaire 16-18 weeks after surgery. Demographic data, preoperative symptoms and the acute disease history were similar between the groups. Operation time, hospital stay and work-off periods were significantly shorter and the number of out-patient procedures was significantly more in Group 2. Although satisfaction scores were similar between the groups, the patients who had no complaint, were "completely satisfied" or would "absolutely recommend the operative technique to other patients" were significantly more in Group 2. In conclusion, the sinus excision technique requires a shorter operation time, hospital stay and work-off period than excision and marsupialization in the treatment of limited, chronic pilonidal disease. The sinus excision technique can be performed as an out-patient procedure in most cases, and seems to be associated with better patient satisfaction.
