Spigelian hernias: a prospective analysis of baseline parameters and surgical outcome of 34 consecutive patients

Most of the papers published on spigelian hernia are either case reports or small retrospective series. In this prospective multicenter study, we aimed to outline the specific features of spigelian hernias and patients’ characteristics more clearly. Surgeons enrolled patients to be entered into the database as they diagnosed and treated the hernias at will. The baseline and surgical outcome parameters were noted in each patient. A painful mass was the main presenting complaint in half of 34 patients. Accurate preoperative diagnosis was possible in 31 patients. Open intraperitoneal mesh repair was the preferred technique. The mean hospital stay and time until return to normal daily activities were 4.1 and 15.6 days. Although a rare condition, diagnosis of a spigelian hernia is not difficult once remembered. Its surgical repair seems to cause few complications and is very well tolerated by the patient.

The added value of the apparent diffusion coefficient calculation to magnetic resonance imaging in the differentiation and grading of malignant brain tumors

OBJECTIVE: ADC calculation can improve the diagnostic efficacy of MR imaging in brain tumor grading and differentiation. METHODS: Apparent diffusion coefficient (ADC) values and ratios of 33 low-grade (23 astrocytomas, 10 oligodendrogliomas) and 40 high-grade (25 metastases and 15 high-grade astrocytomas) malignant tumors were prospectively evaluated. RESULTS: Tumoral ADC values (r=-0.738, P <0.000) and ratios (r=-0.746, P < 0.000) were well correlated with higher degree of malignancy and quite effective in grading of malignant brain tumors (P < 0.000). By using cutoff values of 0.99 for tumoral ADC value and 1.22 for normalized ADC ratio, the sensitivity of MR imaging could be increased from 72.22% to 93.75% and 90.63%, the specificity from 81.08% to 92.68% and 90.24%, PPV from 78.79% to 90.91% and 87.88%, and NPV from 75.00% to 95.00% and 92.50%, respectively. CONCLUSION: ADC calculation was quite effective in grading of malignant brain tumors but not in differentiation of them and added more information to conventional contrast-enhanced MR imaging.     

The Factors Contributing to Death Anxiety in Cancer Patients

Suffering comes in many ways for patients confronting cancer. One of these is an unspecifiable fear about death, which is an existential issue. The aim of this study was to investigate the relationship between death anxiety and its correlates in cancer patients. Seventy cancer patients were assessed using SCID-I, Templer's Death Anxiety Scale, the Hospital Anxiety (A) and Depression (D) Scale, the Distress Thermometer, the Visual Analogue Scale for pain (VAS), the Global Assessment of Functioning, and Glock and Stark's Dimensions of Religious Commitment scales, and these assessments were compared between cancer patients with and without death anxiety. Multiple regression analysis was conducted after correlation analysis between death anxiety and sociodemographic and clinical variables. Axis I psychiatric diagnosis, pain scores, and negative believes about what will happen after death were found to be higher in patients having death anxiety than patients not having death anxiety. Also life expectancy was perceived as shortened in patients with death anxiety. Death anxiety was associated with anxiety, depressive symptoms, and beliefs about what will happen after death. In conclusion, death anxiety could not be regarded as a natural consequence of having cancer; it is associated with the unresolved psychological and physical distress.     

Expression of matrix metalloproteinases in vasculitic neuropathy

The aim of this study was to investigate the expression pattern and cellular source of matrix metalloproteinases (MMP) in vasculitic neuropathy. Matrix metalloproteinases are endopeptidases degrading components of extracellular matrix proteins, and they have been implicated in the pathogenesis of inflammatory demyelination. They are induced by cytokines, secreted by inflammatory cells, and enhance T cell migration. Vasculitic neuropathy occurs as a component of systemic vasculitis or as an isolated angiitis of the peripheral nervous system, and T cell-mediated inflammation is detected in its pathogenesis. Nerve biopsy sections of eight patients with nonsystemic vasculitic neuropathy (NSVN) and four with systemic vasculitic neuropathy were examined for the presence of CD4+, CD8+, and CD68+ cells and immunohistochemically for MMP-2 and MMP-9 expression. Nerve biopsies of eight patients with noninflammatory neuropathy were used as a control group. Semiquantitative polymerase chain reaction analysis was performed to detect MMP-2 and MMP-9 mRNA. The predominant cells were CD8+ and CD68+ T cells. Expression of MMP-9, but not MMP-2, was increased in perivascular inflammatory infiltrate in nerve tissues of vasculitic neuropathy patients. This MMP-9 expression correlated positively with immunostaining of CD8+ T cells. No difference was detected between immunostaining patterns of nonsystemic and systemic vasculitic neuropathies with the antibodies used, except in MMP-9 immunostaining, which was found to be enhanced in NSVN group. Polymerase chain reaction analysis revealed elevated mRNA levels of MMP-9 and MMP-2 compared with controls, but this did not reach statistical significance. Our results imply a pathogenic role for MMP-9 secreted from CD8+ cells in vasculitic neuropathy.

Effect of Intraoperative Valsalva Maneuver Application on Bleeding Point Detection and Postoperative Drainage After Thyroidectomy Surgeries

The purpose of this paper was to analyze the effect of Valsalva maneuver application before finalizing thyroidectomy operations on the identification of bleeding points and postoperational drainage. One hundred patients (age range, 24–76 years) with multinodular goiter, recurrent multinodular goiter, toxic diffuse multinodular goiter, or papillary thyroid cancer were included in the study and were divided into 2 groups of 50 randomly. Both groups underwent thyroidectomy operation, only 1 group received intraoperative Valsalva maneuver application (twice, 30 seconds of 30-cm PEEP). The size of the thyroid gland, the duration of operation, hospital stay, and drain usage were reported. Postoperational occurrences of drainage, hematoma, reoperation, and additional complications were compared between the groups. Valsalva maneuver application helped to identify minor bleeding points in 32% of the cases. There was no significant difference between the study groups regarding the thyroid gland size, operation duration, hospital stay, and the duration of drain usage (P > 0.05 for all). The amount of drainage as well as the frequencies of hematoma, reoperation, and further complications was not significantly different between the study groups (P > 0.05 for all). Intraoperative application of Valsalva maneuver is only useful to detect minor bleeding points in some patients during thyroidectomy operations, but it had no effect on the duration of postoperative drain usage, the amount of drainage, and risk of hematoma. Therefore, intraoperative application of Valsalva maneuver has no beneficial effect on postoperative hemorrhagic complication after thyroidectomy operations.Key words: Drainage, Hemostasis, Thyroidectomy, Valsalva maneuverThyroidectomy is one of the most commonly performed operations worldwide.¹ Though a series of improvements were introduced to the operation process, still several postoperative complications remain to be faced such as seroma, wound infection, skin flap complications, and hematoma.^2,3Despite the richness of the blood vessels in the thyroid area,⁴ the rate of postoperational bleedings thus hematoma events are low (1–5% of the cases).⁵ However, once not controlled, hematoma can result in airway compression and create a life-threatening situation for the patient.⁶ Hence, preventive measures have been emphasized and employed to avoid postoperational bleedings after thyroidectomy. These approaches range from exercises to avoid Valsalva maneuver kind of forces such as coughing or straining at opening bowel⁷ to the use of drains after the operation. However, recent literature indicates that the drain usage does not have a significant effect on the recovery period or on the duration of the hospital stay.^3,5,8,9 Furthermore, it may cause wound infection and contribute to the discomfort of the patients.^5,8,10,11 Thus a proper hemostasis and an early detection of potential bleeding sites are crucial steps for a successful operation and a steady recovery period.⁴ Several techniques have been used to detect and treat bleeding points immediately after the operation to prevent postoperational hematoma. These techniques involve the use of hydrogen peroxide, water in the wound, Valsalva maneuver, and Trendelenburg tilt.^4,7 Recently, the success of Valsalva maneuver and Trendelenburg tilt application on bleeding point detection was demonstrated by Moumoulidis et al.⁴ However, no further information is provided until now regarding the postoperational evaluation of the patients.In this paper, we aim to analyze the effect of the Valsalva maneuver application on the identification of bleeding points before finalizing the surgery and its influence on the postoperative drainage, complications, and recovery process.
