Pattern of abdominal wall herniae in females: a retrospective analysis.

Background: Gender differences are expected to influence the pattern and outcome of management of abdominal wall hernias. Some of these are left to speculations with few published articles on hernias in females. Objectives: To describe the clinical pattern of abdominal wall hernias in females. Method: A 5 year retrospective review. Result: There were 181 female patients with 184 hernias representing 27.9% of the total number of hernia patients operated. Mean age was 41.66±24.46 years with a bimodal peak in the 1st and 7th decades. Inguinal hernia accounted for majority (50.5%) but incisional hernia predominated in the 30-49 age group, while only inguinal and umbilical hernias were seen in the first two decades (p=0.04). There was no side predilection in the cases of inguinal hernia. There were 12 (6.6%) emergency presentations, most of which occurred in the 6th decade and above and none below 30 years (p=0.02). Umbilical (4 cases) and femoral hernias (3 cases) accounted for most of these cases. Incisional hernia was the commonest cause of recurrent hernias. Conclusion: Inguinal hernia is the commonest hernia type in females followed by incisional hernias which also accounteds for most recurrent cases. Age appears to be a risk factor for developing complications.

Hydropic leiomyoma of the uterus presenting as a giant abdominal mass

We describe a case of a 35-year-old woman with a pedunculated uterine leiomyoma with diffuse hydropic degeneration presenting as a giant abdominal mass. The patient was admitted in the emergency department because of diffuse abdominal bloating and discomfort. Ultrasonography (US) showed a heterogeneous abdominopelvic mass. Magnetic resonance imaging (MRI) was performed to further characterise and revealed a myometrial pedunculated tumour. Despite its marked T2-signal heterogeneity and volume, there were no other suspicious findings to suggest a malignant nature; therefore, fertility-sparing myomectomy was performed. Leiomyomas frequently undergo degenerative changes altering their imaging appearances. Leiomyomas with uncommon degenerative changes may be difficult to differentiate from malignant myometrial tumours, based solely on imaging. To the best of our knowledge, a diffuse hydropic degeneration imaging appearance has only been described twice in the literature. We describe the imaging appearance of this rare form of leio

Evaluación del abordaje diagnóstico del trauma abdominal en la Unidad de Emergencia del Hospital Nacional Rosales.

El trauma abdominal es la tercera causa de muerte. Durante años se han utilizado muchos métodos diagnósticos para la evaluación del trauma abdominal: actualmente los utilizados son el lavado peritoneal diagnóstico, el cual es muy sensible pero invasivo y la ultrasonografía en formato enfocado FAST, una buena opción. Igualmente la tomografía computarizada ha mostrado buena sensibilidad diagnostica y ser no invasiva. Materiales y métodos: Se realizó un estudio descriptivo de seguimiento de una cohorte de pacientes que consultaron con trauma abdominal en la Unidad de Emergencia del HNR en el periodo de junio 2012 a mayo 2013, en quienes se utilizó métodos diagnósticos para dicho trauma abdominal. Se realizó también evaluación de pruebas diagnósticas. Resultados: Se encontró una muestra de 278 pacientes que cumplían criterios de inclusión. El lavado peritoneal fue el método más utilizado en nuestra serie en 147 pacientes (52.9%) seguido por el FAST 128 (46%). La modalidad de uso del lavado peritoneal fue de indicación en los pacientes con estado de choque y Glasgow más severo, y en traumas abiertos. La sensibilidad del lavado peritoneal fue de 100%, con especificidad del 87.5, y del FAST sensibilidad del 100% y especificidad del 91,80%. Conclusiones: El lavado peritoneal diagnóstico en nuestra serie fue el método más utilizado y en los pacientes con mayor grado de severidad de choque y Glasgow.

Abdominal epilepsy as an unusual cause ofabdominal pain: a case report.

Introduction: Abdominal pain, in etiology sometimes difficult to be defined, is a frequent complaint in childhood. Abdominal epilepsy is a rare cause of abdominal pain. Objectives: In this article, we report on 5 year old girl patient with abdominal epilepsy. Methods: Some investigations (stool investigation, routine blood tests, ultrasonography (USG), electrocardiogram (ECHO) and electrocardiograpy (ECG), holter for 24hr.) were done to understand the origin of these complaints; but no abnormalities were found. Finally an EEG was done during an episode of abdominal pain and it was shown that there were generalized spikes especially precipitated by hyperventilation. The patient did well on valproic acid therapy and EEG was normal 1 month after beginning of the treatment. Discussion: The cause of chronic recurrent paroxymal abdominal pain is difficult for the clinicians to diagnose in childhood. A lot of disease may lead to paroxysmal gastrointestinal symptoms like familial mediterranean fever and porfiria. Abdominal epilepsy is one of the rare but easily treatable cause of abdominal pain. Conclusion: In conclusion, abdominal epilepsy should be suspected in children with recurrent abdominal pain.

A home-based treadmill training reduced epicardial and abdominal fat in postmenopausal women with metabolic syndrome

Introduction: The current study was designed to determine the effect of home-based treadmill training on epicardial and abdominal adipose tissue in postmenopausal women with metabolic syndrome (MS). A secondary objective was to identify significant correlations between imaging and conventional anthropometric parameters. Material and methods: Sixty postmenopausal women with MS volunteered for the current trial. Thirty were randomly assigned to perform a supervised home-based 16-week treadmill training program, 3 sessions/week, consisting of a warm-up, 30-40 min treadmill exercise (increasing 5-minutes each 4-weeks) at a work intensity of 60-75% of peak heart rate (increasing 5% each 4-weeks) and cooling-down. Epicardial fat thickness (EFT) was assessed by echocardiography. Abdominal fat mass in the lumbar regions L1-L4 and L4-L5 was determined by dual X-ray absorptiometry. Results: Epicardial fat thickness and abdominal fat percentages were significantly improved after the completion of the training program. Another striking feature of the current study was the moderate correlation that was found between EFT and waist circumference (WC). Conclusion: Home-based treadmill training reduced epicardial and abdominal fat in postmenopausal women with MS. A secondary finding was that a moderate correlation was found between EFT and WC. While current investigations are promising, future studies are still required to consolidate this approach in clinical application.

Nutritional status and its impact on time and relocation in postoperative complications of abdominal patients undergoing surgery

Introduction: The nutritional state is the independent factor that most influences the post-operational results in elective surgeries. Objective: to evaluate the influence of the nutritional state on the hospitalization period and on the post-operative complications of patients submitted to abdominal surgery. Methods: prospective study with 99 surgical patients over 18 years of age, submitted to abdominal surgeries in the period from April to October of 2013, in the Instituto de Medicina Integral Professor Fernando Figueira (IMIP). All patients were submitted to anthropometric nutritional evaluations through the body mass Index (BMI), arm circumference (AC) and triceps skinfold thickness (TEST). The biochemical evaluation was carried out from the leukogram and serum albumin results. The identification of candidate patients to nutritional therapy (NT) was carried out through the nutritional risk (NR) evaluation by using the BMI, loss of weight and hypoalbuminemia. The information about post-operational complications, hospitalization period and clinical diagnosis was collected from the medical records. Program SPSS version 13.0 and significance level of 5% were used for the statistical analysis. Results: The malnutrition diagnosed by the AC showed significant positive association with the presence of post-operative complications (p=0.02) and with hospitalization period (p=0.02). The presence of NR was greater when evaluated by hypoalbuminemia (28.9%), however, only 4% of the sample carried out the NT in the pre-operational period. The hospitalization period was greater for patients with malignant neoplasia (p<0.01). Conclusion: The malnutrition diagnosis of patients submitted to abdominal surgeries is associated to greater risk of post-operational complications and longer hospitalization permanence.

Relationship between waist circumference and sagittal abdominal diameter measured at different anatomical sites and inflammatory biomarkers in apparently health men

Introduction: Visceral fat accumulation is associated with several changes, such as, increased production of inflammatory biomarkers, especially, C-reactive protein (CRP) and fibrinogen. Anthropometric measurements for central adiposity evaluation, such as, waist circumference (WC) and sagittal abdominal diameter (SAD) have been highlighted. However, there is no consensus on the best anatomical site for measurement. Objective: To evaluate the reliability of different measurements of WC and SAD and verify their capacity to discriminate changes in inflammatory biomarkers. Method: 130 men (20-59 years) were assessed, having measurements of weight, height, WC and SAD. It was considered as the cutoff point for high-sensitivity CRP (hs-CRP) values ≥ 0.12 mg/dL and for fibrinogen the 50th percentile of the evaluated sample. Results: All measurements presented an intraclass correlation coefficient between 0.998 and 0.999. WC measured at the umbilical level (AUC=0.693±0.049) and the smallest circumference between the thorax and the hips (AUC=0.607±0.050) had greater ability to discriminate changes in concentrations of hs-CRP and fibrinogen, respectively. SAD (umbilical level) showed the better ability to detect changes in concentrations of hs-CRP (AUC=0.698± 0.049) and fibrinogen (AUC=0.625±0.049), according to the ROC analysis (p<0.05). Conclusion: WC (smallest circumference between the thorax and the hips) and SAD (umbilical level) are the anatomic sites of measurement for use in predicting the inflammatory risk in apparently health men.

Abdominal hyperalgesia in secretory phospholipase A(2)-induced rat pancreatitis: Distinct roles of NK1 receptors

We investigated the potential of secretory phospholipase A(2) (sPLA(2))-induced pancreatitis to promote abdominal hyperalgesia, as well as to depolarize sensory fibres in vitro using a grease-gap technique. Pancreatitis was induced by the injection of sPLA(2) from Crotalus durissus terrificus (sPLA(2) Cdt, 300 mu g kg(-1)) venom into the common bile duct of rats. Pancreatic inflammatory signs, serum amylase levels and abdominal hyperalgesia were evaluated in rats treated or not with SR140333, a tachykinin NK1 receptor antagonist. Injection of sPLA(2) Cdt caused pancreatic oedema formation and increased pancreatic neutrophil infiltration and serum amylase at 4 h, which returned to normality by 24 h, except for the neutrophil infiltration, which was still increased at this time point. Animals injected with sPLA(2) exhibited a lower withdrawal threshold to electronic von Frey stimulation in the upper abdominal region at 4 h, but not 24 h, post-injection when compared with saline-injected rats. Pre-treatment of animals with SR140333 significantly reduced the sPLA(2) Cdt-induced abdominal hyperalgesia, without affecting the other parameters. Neither sPLA(2) Cdt nor sPLA(2) from Naja mocambique mocambique venom depolarized capsaicin-sensitive sensory fibres from rat vagus nerve, but they decreased the propagated compound action potentials in both A and C fibres. These data show for the first time that NK1 receptors play an important role in the early abdominal hyperalgesia in a rat model of sPLA(2)-induced pancreatitis, suggesting that these receptors are of importance in the development of pain in the pancreatitis condition. We also provide evidence that sPLA(2)s do not directly depolarize sensory fibres in vitro. (C) 2011 European Federation of International Association for the Study of Pain Chapters.

Management of the clinical issue of constipation with abdominal complaints in adults: a national survey of Primary Care physicians and gastroenterologists

Irritable bowel syndrome and functional constipation represent a relevant and common health issue. However, real-world clinical practice includes patients with constipation who may or may not have other abdominal complaints (pain, bloating, abdominal discomfort) with variable frequency. The goal of the present study was to obtain information on the workload entailed by patients with constipation and associated abdominal complaints, predominant clinical behaviors, education needs, and potential daily practice aids both in Primary Care and gastroenterology settings. The clinical behavior of doctors is generally similar at both levels, despite differences in healthcare approach: use of empiric therapies and clinically guided diagnostic tests, with some differences in colonoscopy use (not always directly accessible from Primary Care). Regarding perceptions, general support and osmotic laxatives are most valued by PC doctors, whereas osmotic laxatives, combined laxatives, and linaclotide are most valued by GE specialists. Furthermore, over half of respondents considered differentiating both diagnoses as challenging. Finally, considerable education needs are self-acknowledged at both levels, as is a demand for guidelines and protocols to help in managing this issue in clinical practice. A strength of this study is its providing a joint photograph of the medical approach and the perceptions of constipation with abdominal discomfort from a medical standpoint. Weaknesses include self-declaration (no formal validation) and a response rate potentially biased by professional motivation.

Prevalence of General and Abdominal Obesity in a Nationally Representative Sample of Iranian Children and Adolescents: The CASPIAN-IV Study

Background: Pediatric obesity is one of the predisposing risk factors for many non-communicable diseases. Objectives: The purpose of this study was to estimate the national prevalence of general and abdominal obesity among Iranian children and adolescents. Patients and Methods: This cross-sectional nation-wide study was performed in 30 provinces in Iran among 14880 school students aged 6 – 18 years, selected by multistage random cluster sampling. The World Health Organization growth curve was used to categorize Body Mass Index (BMI). Obesity was defined as BMI equal to or higher than the age- and gender-specific 95th percentile; abdominal obesity was considered as waist-to-height ratio of more than 0.5. Results: Data of 13486 out of 14880 invited students were complete (response rate of 90.6%). They consisted of 6543 girls and 75.6% urban residents, and had a mean age of 12.45 (95% CI: 12.40 - 12.51) years. The prevalence rate of general and abdominal obesity was 11.89% (13.58% of boys vs. 10.15% of girls) and 19.12% (20.41% of boys vs. 17.79% of girls), respectively. The highest frequency of obesity was found in the middle school students (13.87% general and 20.84% abdominal obesity). The highest prevalence of general obesity was found in Boushehr (19%) followed by Guilan and Mazandaran (18.3%, 18.3%), while the lowest prevalence was observed in Hormozgan (2.6%). The highest frequency of abdominal obesity was found in Mazandaran (30.2%), Ardabil (29.2%) and Tehran (27.9%). Provinces such as Sistan-Baloochestan (8.4%), Hormozagan (7.4%), and Kerman (11.4%) had the lowest prevalence of abdominal obesity. The Southern and South Eastern provinces had the lowest prevalence of general obesity (2.6% and 5.6%) and abdominal obesity (7.4% and 8.8%). Moreover, the highest prevalence of obesity was found in North and North West Iran by maximum frequency of 18.3% general obesity and 30.2% of abdominal obesity. Conclusions: The results showed a high prevalence of general and abdominal obesity among boys living in the Northern provinces of Iran. The present study provides insights that policy makers should consider action-oriented interventions for prevention and control of childhood obesity at national and sub-national level.
