Bowel obstruction caused by broad ligament hernia sucessfully repaired by laparoscopy.

Internal hernais are rare bowel obstructions. We present a case of small bowel obstruction in a 37-year-old woman caused by internal herniation through a defect in broad ligament, which was managed by laparoscopic surgery.

Neutrophil-to-Lymphocyte Ratio Predicts the Severity of Incarcerated Groin Hernia.

BACKGROUND The incarceration of a segment of bowel within a groin hernia can result in intestinal strangulation if hernia treatment is delayed. Once intestinal strangulation occurs, a bowel resection may be required, and there is an overall increased risk for postoperative complications. The aim of this study was to identify biomarkers to predict the severity of an incarcerated groin hernia. MATERIAL AND METHODS We retrospectively evaluated the records of 95 patients with incarcerated groin hernias who underwent emergency surgical correction of the hernias. The need for a bowel resection was regarded as an indicator of severity in incarcerated groin hernia patients. The patients were divided into 2 groups: patients with bowel resection surgery and patients without bowel resection surgery. RESULTS We discovered that leukocyte count (leukocyte count ≥10×10³/mm³), neutrophil-to-lymphocyte ratio (NLR, NLR ≥11.5), presentation of bowel obstruction, and duration of incarceration (duration of incarceration ≥26 h) were significantly associated with bowel resection in incarcerated groin hernia patients by using the chi-square test. Factors such as leukocyte count, NLR, presentation of bowel obstruction, and duration of incarceration were analyzed using multivariate logistic regression analysis. We found that NLR, presentation of bowel obstruction, and duration of incarceration were independently and significantly related to bowel resection in incarcerated groin hernia patients. CONCLUSIONS An elevated NLR can serve as a biomarker for the prediction of severity of incarcerated groin hernias. Additionally, incarcerated groin hernia patients who present with bowel obstruction or with duration of intestinal incarceration longer than 26 h have an increased risk for bowel resection.

Comparison of protein immunoprecipitation-multiple reaction monitoring with ELISA for assay of biomarker candidates in plasma.

Quantitative analysis of protein biomarkers in plasma is typically done by ELISA, but this method is limited by the availability of high-quality antibodies. An alternative approach is protein immunoprecipitation combined with multiple reaction monitoring mass spectrometry (IP-MRM). We compared IP-MRM to ELISA for the analysis of six colon cancer biomarker candidates (metalloproteinase inhibitor 1 (TIMP1), cartilage oligomeric matrix protein (COMP), thrombospondin-2 (THBS2), endoglin (ENG), mesothelin (MSLN) and matrix metalloproteinase-9 (MMP9)) in plasma from colon cancer patients and noncancer controls. Proteins were analyzed by multiplex immunoprecipitation from plasma with the ELISA capture antibodies, further purified by SDS-PAGE, digested and analyzed by stable isotope dilution MRM. IP-MRM provided linear responses (r = 0.978-0.995) between 10 and 640 ng/mL for the target proteins spiked into a "mock plasma" matrix consisting of 60 mg/mL bovine serum albumin. Measurement variation (coefficient of variation at the limit of detection) for IP-MRM assays ranged from 2.3 to 19%, which was similar to variation for ELISAs of the same samples. IP-MRM and ELISA measurements for all target proteins except ENG were highly correlated (r = 0.67-0.97). IP-MRM with high-quality capture antibodies thus provides an effective alternative method to ELISA for protein quantitation in biological fluids.

Serial urological interventions including circumcision in a hemophilic child with inhibitors.

Hemophilia patients sometimes need careful treatment of urgent serious bleedings and management of some surgeries. Development of inhibitor has some impact on the management of these situations. Here a case of patient of hemophilia A is presented in whom urological surgery resulted in inhibitor development and a second operation with bypass agent.

D-dimer levels in the prediction of the degree of intestinal necrosis of etrangulated hernias in rats.

PURPOSE: The aim of this study was to investigate the time-dependent relation between plasma D-dimer levels and the degree of intestinal necrosis and to compare these parameters with leukocyte counts in an experimental etrangulated hernia model in rats. RESULTS: When the duration of intestinal ischemia was prolonged, serum D-dimer levels increased relative to the control group, with the difference being statistically significant at hour 2 (P = 0.027). In contrast, leukocyte counts in the 2- and 4-h strangulation group were higher that those of the control group, but the difference was not statistically significant (P = 0.625 and P = 0.846, respectively). However, in the 6-h strangulation group the levels of leukocytes were significantly higher that those of the control group (P = 0.015). CONCLUSION: Serum D-dimer measurements may be used as a more valuable diagnostic parameter than leukocyte count in the early diagnosis of intestinal ischemia, including strangulated hernia.

Is D-dimer a predictor of strangulated intestinal hernia?

BACKGROUND: The goal of this study was to assess the relevance of serum D-dimer measurement as a possible reliable marker for the diagnosis of strangulated intestinal hernia. METHODS: Consecutive patients admitted with nontraumatic acute abdominal gastrointestinal disorders were recruited prospectively in a tertiary referral hospital. The study was conducted in 159 patients between August 2002 and April 2004. D-dimer, lactate dehydrogenase, serum amylase, and international normalized ratio (INR) levels were tested in the emergency room prior to surgical intervention. For each patient, 15 variables, including D-dimer, were available for analysis. RESULTS: Thirty-three (20.7%) of the 159 patients had intestinal ischemia, and 28 (85%) of these 33 patients had D-dimer level > 300 ng/ml. Plasma levels of D-dimer in patients with intestinal ischemia were significantly higher than in patients without ischemia (P < 0.05). There were 29 (18.2%) patients in the hernia group with incarceration (n = 22) or strangulation requiring resection (n = 7). D-dimer levels in patients requiring intestinal resection were insignificantly higher than in patients without resection (P > 0.05). Six (85%) of the 7 hernia patients requiring resection had D-dimer levels > 360 ng/ml. The D-dimer variable correlated best with the leukocyte count in patients with hernia requiring resection. Levels of lactate dehydrogenase, serum amylase, and INR did not show any correlation with D-dimer levels. CONCLUSIONS: To help predict ischemic events, the increasing use of the D-dimer assay in clinical practice could be extended to patients presenting with intestinal emergencies. An elevated D-dimer level on admission had a high sensitivity for identifying patients with intestinal ischemia, although it had a low specificity. Whether it is predictive or preventive for resection in strangulated intestinal hernia patients still remains a question.

Mast cell quantification in normal peritoneum and during peritoneal dialysis treatment.

CONTEXT: Mast cells (MCs) have been implicated in fibrogenesis, angiogenesis, and immunity against bacteria. These 3 mechanisms participate in the peritoneal pathology secondary to peritoneal dialysis (PD) treatment. Despite their potential relevance to PD-related pathology, few studies have focused on MCs. OBJECTIVE: To evaluate possible variations in the number of MCs during PD treatment. DESIGN: A quantitative study of tissue MCs in normal and pathologic peritoneum. Parietal peritoneal biopsies were collected from 4 groups: (1) normal controls (n = 9), (2) uremic non-PD patients (n = 16), (3) uremic patients on PD (n = 26), and (4) non-renal patients with inguinal hernia (n = 20). MCs were evaluated using immunohistochemistry for the detection of tryptase. The total number of cross sections of vessels per peritoneal field was examined in 22 of the 26 peritoneal biopsies of PD patients. RESULTS: PD tissue samples showed fibrosis, mesothelial cell loss, and variable hyalinizing vasculopathy. The number of MCs was similar in normal controls and non-PD uremic patients (mean +/- SE: 7.13 +/- 0.67 and 7.74 +/- 0.74 MCs/mm2, respectively). Peritoneal dialysis patients showed a reduction (4 +/- 0.38 MCs/mm2, P < .001), whereas hernia sac samples showed an increase (10.59 +/- 3.48 MCs/mm2). MC reduction showed no correlation with time on dialysis, fibrosis, number of vessels, or previous episodes of peritonitis. CONCLUSIONS: The peritoneum of patients receiving PD treatment shows a reduction of MCs. Despite such a reduction, fibrosis takes place, suggesting that MCs do not play a critical role in fibrosis genesis. Mast cell loss may be a contributory factor to peritonitis episodes in PD patients.

Brain concussion produces transient hypokalemia in children.

Hyperglycemia and hypokalemia caused by catecholamine discharge have been reported to occur in patients after severe head trauma. The aim of this prospective study was to evaluate whether a similar neuroendocrine and metabolic response is found in children after minor head trauma such as brain concussion (Glasgow Coma Scale (GCS) > or = 13). One hundred fifty patients aged 2 to 14 years (average, 6 years) were divided into three groups (n = 50 in each group). Group 1 included patients admitted to the emergency department for brain concussion (Glasgow Coma Scale (GCS) > or = 13); group 2 included patients admitted for fractures of long bones without head injury; and group 3 were control patients electively admitted for hernia repair. All patients had complete physical and neurological examinations. Complete blood count and blood chemistry were obtained on admission. All blood tests were repeated at 6, 12, and 24 hours in patients belonging to group 1. An electrocardiogram was obtained in selected patients and catecholamine levels were measured in some patients. Statistical analysis was performed using analysis of variance (ANOVA). Serum potassium and sodium levels in patients with brain concussion (group 1) were 3.6 +/- 0.6 and 136 +/- 3 mEq/L, respectively and were significantly lower (P < 0.01) than those in patients belonging to group 2, 4 +/- 0.4 and 138 +/- 3, respectively, and the controls (group 3), 4.2 +/- 0.5 and 140 +/- 2, respectively. Serum glucose level was 124 +/- 34 and 118 +/- 32 mg% in groups 1 and 2 and was significantly higher than that of the controls (group 3), 90 +/- 23 mg%. There was no correlation between serum electrolytes and GCS. No electrocardiogram changes or elevation of serum catecholamines were found. Hypokalemia resolved spontaneously within 24 hours. All patients recovered without neurological sequalae. Transient hypokalemia frequently occurs in children even with minor head trauma. This hypokalemia resolves spontaneously, without treatment and within 24 hours.

Serum testosterone and estradiol 17-beta concentrations in 15 dogs with perineal hernia.

Serum testosterone and estradiol 17-beta concentrations, and serum testosterone-to-estradiol ratio were evaluated in 15 dogs (greater than or equal to 5 years old) with perineal hernia (9 sexually intact males and 6 castrated males) and in 9 clinically normal sexually intact male dogs greater than or equal to 5 years old. There was no significant difference in serum testosterone-to-estradiol ratio between sexually intact male dogs with perineal hernia and clinically normal sexually intact male dogs. In castrated dogs with perineal hernia, serum testosterone concentration and testosterone-to-estradiol ratio were significantly (P less than 0.05) lower, compared with those values in sexually intact dogs with perineal hernia and in clinically normal sexually intact male dogs. There was no significant difference in serum estradiol 17-beta concentration among sexually intact male dogs with perineal hernia, castrated dogs with perineal hernia, and clinically normal sexually intact male dogs. Serum testosterone and estradiol 17-beta concentrations in dogs with perineal hernia did not differ from those values in clinically normal male dogs of the same age. Castration cannot be recommended for the treatment of perineal hernia unless a castration-responsive contributing factor such as prostatomegaly is identified, unless the pelvic diaphragm of dogs with perineal hernia has high sensitivity to normal or low serum testosterone and estradiol 17-beta concentrations, or unless there is documentation that other androgens and/or estrogens are involved.

Possible correlation between tumor invasiveness and low serum cholesterol.

The predisposition to solid tumor of individuals with low serum cholesterol may correlate with membrane properties of the emerging neoplastic cells. Evidence is presented to indicate that cholesterol content in the membrane of tumor cells is adjusted with respect to the serum cholesterol. Upon incorporation of cholesterol, tumor cells, which are exemplified here by colon and gastric carcinoma cells, become substantially more immunogenic and therefore more susceptible to clearance by the immune system.

[Several kinin system indices in diseases of the thyroid gland]. / Nekotorye pokazateli kininovoi sistemy pri zabolevaniiakh shchitovidnoi zhelezy.

Content of free bradikinin, kininogen and kininase activity were studied using biological methods in blood serum of 112 patients with goiter, of 20 patients with instrangulated hernia and of 21 healthy persons. The patterns studied were similar to normal value in patients with euthyroid goiter and instrangulated hernia. Thyrotoxicosis (63 patients) was accompanied by increase in all the patterns studied and the alterations were most pronounced in severe form of the impairment. Content of kininogen and kininase activity were increased about 2-fold and bradikinin content--5-fold. Content of free bradikinin was increased and kininase activity was decreased in all groups of patient within 1--3 days after the operation. Content of kininogen was increased in euthyroid goiter and decreased in thyrotoxic one. Patterns of kinine system trended to normalization within 6 days after the operation.
