  1. Abdominal muscle training in sport.

    Norris, C M

    1993-01-01

    This paper evaluates several abdominal exercises, and highlights factors which are important for their safe prescription and effective use. The function of the abdominal muscles and hip flexors is considered, and the importance of the infra-umbilical portion of the rectus abdominis is emphasized. The effects of flexion on the lumbar spine are outlined. The trunk curl, sit-up, and straight leg raise are analysed, together with modifications of these exercises. The effect of foot fixation and h...

    Jensen, K K; Kjaer, M; Jorgensen, L N

    2014-01-01

    PURPOSE: Although ventral incisional hernia (VIH) repair in patients is often evaluated in terms of hernia recurrence rate and health-related quality of life, there is no clear consensus regarding optimal operative treatment based on these parameters. It was proposed that health-related quality...... of life depends largely on abdominal muscle function (AMF), and the present review thus evaluates to what extent AMF is influenced by VIH and surgical repair. METHODS: The PubMed and EMBASE databases were searched for articles following a systematic strategy for inclusion. RESULTS: A total of seven...... studies described AMF in relation to VIH. Five studies examined AMF using objective isokinetic dynamometers to determine muscle strength, and two studies examined AMF by clinical examination-based muscle tests. CONCLUSION: Both equipment-related and functional muscle tests exist for use in patients...

  3. Abdominal muscle paralysis associated with herpes zoster.

    Gottschau, P; Trojaborg, W

    1991-10-01

    We describe a 77-year-old women with cutaneous herpes zoster in the area of the right T9-T11 dermatomes complicated by abdominal muscle paralysis. Four months after onset of paralysis, stimulation of appropriate intercostal nerves failed to evoke responses from the corresponding segments of the rectus abdominis muscle. Three months later EMG of these muscle segments revealed profuse denervation activity and spontaneous long-lasting burst of high frequency discharges. Magnetic stimulation applied transcranially and peripherally at T10 evoked responses from the left, but not from the right paralytic rectus abdominis muscle. Electric stimulation of right T10 elicited a markedly delayed, prolonged and polyphasic response in the transverse abdominis muscle and EMG revealed polyphasia and increased motor unit potential duration in muscle segments underlying herpes zoster eruption. One and a half years after onset, the paralysis of the rectus abdominis muscle was still present. A survey of the literature concerning this rare type of zoster paralysis is presented. PMID:1837649

    [Purpose] The purpose of this study was to determine whether forced expiration is correlated with abdominal muscle thickness. [Subjects] Twenty-three healthy male volunteers participated in this study. [Methods] The peak expiratory flow (PEF) was obtained using a peak flow meter with subjects in the sitting position. The thicknesses of the right rectus abdominis, external oblique, internal oblique, and transverse abdominis muscles were measured using B-mode ultrasonography at the end of a rel...

  5. Abdominal perforator vs. muscle sparing flaps for breast reconstruction.

    Butler, Paris D; Wu, Liza C

    2015-06-01

    Abdominally based free flaps have become the mainstay for women that desire to use their own tissue as a means of breast reconstruction after mastectomy. As the techniques have evolved, significant effort has been invested in finding the best means of minimizing morbidity to the abdominal donor site while ensuring a viable reconstructed breast that is aesthetically pleasing. This manuscript reviews and compares the muscle sparing free transverse rectus abdominis myocutaneous (MsfTRAM), the deep inferior epigastric artery perforator (DIEP), and the superficial inferior epigastric artery (SIEA) flaps, regarding flap success rate, operative times, abdominal donor site morbidity and residual functionality, hospital lengths of stay and associated costs, impact of co-morbid conditions, and resilience after adjuvant radiation treatment.

    Giacomini, Mateus Beltrame; da Silva, Antônio Marcos Vargas; Weber, Laura Menezes; Monteiro, Mariane Borba

    2016-04-01

    The aim of this study was to verify the effects of the Pilates Method (PM) training program on the thickness of the abdominal wall muscles, respiratory muscle strength and performance, and lung function. This uncontrolled clinical trial involved 16 sedentary women who were assessed before and after eight weeks of PM training. The thickness of the transversus abdominis (TrA), internal oblique (IO) and external oblique (EO) muscles was assessed. The respiratory muscle strength was assessed by measuring the maximum inspiratory (MIP) and expiratory (MEP) pressure. The lung function and respiratory muscle performance were assessed by spirometry. An increase was found in MIP (p = 0.001), MEP (p = 0.031), maximum voluntary ventilation (p = 0.020) and the TrA (p < 0.001), IO (p = 0.002) and EO (p < 0.001) thickness after the PM program. No alterations in lung function were found. These findings suggest that the PM program promotes abdominal wall muscle hypertrophy and an increase in respiratory muscle strength and performance, preventing weakness in abdominal muscles and dysfunction in ventilatory mechanics, which could favor the appearance of illnesses.

    Kwon, Yu-Jeong; Hyung, Eun-Ju; Yang, Kyung-Hye; Lee, Hyun-Ok

    2014-08-01

    [Purpose] The purpose of this study was to examine the activities of the abdominal muscles of women who had experienced vaginal delivery in comparison with those who had experienced Cesarean childbirth. [Subjects and Methods] A total of 14 subjects (7 vaginal delivery, 7 Cesarean section) performed an active straight leg raise to 20 cm above the ground, and we measured the activities of the internal oblique abdominal muscle, the external oblique abdominal muscle, and the rectus abdominal muscle on both sides using electromyography. The effort required to raise the leg was scored on a Likert scale. Then, the subjects conducted maximum isometric contraction for hip joint flexion with the leg raised at 20 cm, and maximum torque and abdominal muscle activities were measured using electromyography. [Results] During the active straight leg raise, abdominal muscle activities were higher in the Cesarean section subjects. The Likert scale did not show a significant difference. The activities of the abdominal muscles and the maximum torque of the hip joint flexion at maximum isometric contraction were higher in the vaginal delivery subjects. [Conclusion] The abdominal muscles of Cesarean section subjects showed greater recruitment for maintaining pelvic stability during the active straight leg raising, but were relatively weaker when powerful force was required. Therefore, we consider that more abdominal muscle training is necessary for maintaining pelvic stability of Cesarean section subjects. PMID:25202194

    Soraya Pirouzi

    2013-12-01

    Full Text Available Background: Stabilization exercises can improve the performance of trunk and back muscles, which are effective in the prevention and treatment of low back pain. The four-point kneeling exercise is one of the most common types of stabilization exercises. This quasi-experimental study aimed to evaluate and compare the level of activation between abdominal and lumbar muscles in the different stages of the four-point kneeling exercise. Methods: The present study was conducted on 30 healthy women between 20 and 30 years old. Muscle activity was recorded bilaterally from transversus abdominis, internal oblique, and multifidus muscles with an electromyography (EMG device during the different stages of the four-point kneeling exercise. All the collected EMG data were normalized to the percentage of maximum voluntary isometric contraction. The repeated measures ANOVA and paired t-test were used for the statistical analysis of the data. Results: A comparison between mean muscle activation in right arm extension and left leg extension showed that left internal oblique and left transverse abdominis muscles produced greater activation during left leg extension (P<0.05. The comparison of mean muscle activation between right arm extension and the bird-dog position showed that, except for the right internal oblique, all the muscles produced higher activation in the bird-dog stage (P<0.05. In comparison to the bird-dog stage, the left multifidus showed high activation during left leg extension (P<0.05. Conclusion: The results of this study showed that the activity of all the above-mentioned muscles during quadruped exercise can provide stability, coordination, and smoothness of movements.

    2015-10-01

    Full Text Available The present paper’s aim is to elaborate a program of postoperative recovery for patients suffering from abdominal parietal defects, and to indicate the beneficial implications, both of the preoperative preparations and of the postoperative physiotherapist actions. The programs of functional postoperative recovery have been elaborated individually for the 254 patients under study – of which 139 belong to lot A (operated under a scheduled regime, after the preoperative preparation and 115 belong to lot B (operated in an emergency regime, in the General Surgery Clinic III of the University Emergency Hospital of Bucharest, between 1998 and 2009. The postoperative recovery program has been individualized for each patient, depending on his / her pathology and co-morbidities, and the physiotherapist has trained and took care that the patients should execute exercises of respiratory re-education, active mobilization of their limbs, coordinated with the breath, isometric exercises for the toning of their arms and legs and of the abdomen muscles. They started the muscle toning exercises slowly and increased them progressively in duration and intensity. The recovery started with isometric-type exercises and continued with the isotonic-type ones. Though mainly the abdominal muscles are aimed at, respectively the flexor muscles of the torso, the physiotherapy program shall comprise the toning of the other muscle groups of the torso, as well. It has been noticed - for the patients in lot A, compared to those of lot B - an obvious net favorable postoperative evolution, characterized through: a reduction of the respiratory, cardiac and thromboembolic complications, a quick postoperative recovery and the immediate social reintegration. An overview of the two lots proves the importance of the cardio-respiratory and locomotive preparation of the patients suffering from big abdominal parietal defects. The simple gestures of respiratory re-education, of

  11. An oblique muscle hematoma as a rare cause of severe abdominal pain: a case report

    Shimodaira Masanori

    2013-01-01

    Full Text Available Abstract Background Abdominal wall hematomas are an uncommon cause of acute abdominal pain and are often misdiagnosed. They are more common in elderly individuals, particularly in those under anticoagulant therapy. Most abdominal wall hematomas occur in the rectus sheath, and hematomas within the oblique muscle are very rare and are poorly described in the literature. Here we report the case of an oblique muscle hematoma in a middle-aged patient who was not under anticoagulant therapy. Case presentation A 42-year-old Japanese man presented with a painful, enlarging, lateral abdominal wall mass, which appeared after playing baseball. Abdominal computed tomography and ultrasonography showed a large soft tissue mass located in the patient’s left internal oblique muscle. A diagnosis of a lateral oblique muscle hematoma was made and the patient was treated conservatively. Conclusion Physicians should consider an oblique muscle hematoma during the initial differential diagnosis of pain in the lateral abdominal wall even in the absence of anticoagulant therapy or trauma.

  13. Comparison of changes in the contraction of the lateral abdominal muscles between the abdominal drawing-in maneuver and breathe held at the maximum expiratory level.

    Ishida, Hiroshi; Hirose, Ryohei; Watanabe, Susumu

    2012-10-01

    The abdominal drawing-in maneuver (ADIM) is commonly used as a fundamental component of lumbar stabilization training programs. One potential limitation of lumbar stabilization programs is that it can be difficult and time consuming to train people to perform the ADIM. The transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles are the most powerful muscles involved in expiration. However, little is known about the differences in the recruitment of the abdominal muscles between the ADIM and breathe held at maximum expiratory level (maximum expiration). The thickness of the TrA and IO muscles was measured by ultrasound imaging, and the activity of the EO muscle was measured by electromyography (EMG) in 33 healthy male performing the ADIM and maximum expiration. Maximum expiration produced a significant increase in the thickness of the TrA and IO muscles compared to the ADIM (p method for training of co-activation of the lateral abdominal muscles.

    2015-01-01

    Objective To investigate the changes of activation of the abdominal muscles depending on exercise angles and whether the activation of rectus abdominis differs according to the location, during curl up and leg raise exercises, by measuring the thickness ratio of abdominal muscles using ultrasonography. Methods We examined 30 normal adults without musculoskeletal problems. Muscle thickness was measured in the upper rectus abdominis (URA), lower rectus abdominis (LRA), obliquus externus (EO), obliquus internus (IO), and transversus abdominis (TrA), at pre-determined angles (30°, 60°, 90°) and additionally at the resting angle (0°). Muscle thickness ratio was calculated by dividing the resting (0°) thickness for each angle, and was used as reflection of muscle activity. Results The muscle thickness ratio was significantly different depending on the angles in URA and LRA. For curl up-URA p=0 (30°90°), p=0.44 (30°90°), p=0.44 (30°>90°), respectively, by one-way ANOVA test-and for leg raise-URA p=0 (30°<60°), p=0 (60°<90°), p=0 (30°<90°) and LRA p=0.01 (30°<60°), p=0 (60°<90°), p=0 (30°<90°), respectively, by one-way ANOVA test-exercises, but not in the lateral abdominal muscles (EO, IO, and TrA). Also, there was no significant difference in the muscle thickness ratio of URA and LRA during both exercises. In the aspect of muscle activity, there was significant difference in the activation of RA muscle by selected angles, but not according to location during both exercises. Conclusion According to this study, exercise angle is thought to be an important contributing factor for strengthening of RA muscle; however, both the exercises are thought to have no property of strengthening RA muscle selectively based on the location.

  18. Recruitment and plasticity in diaphragm, intercostal, and abdominal muscles in unanesthetized rats

    Navarrete-Opazo, A.; Mitchell, G.S.

    2014-01-01

    Although rats are a frequent model for studies of plasticity in respiratory motor control, the relative capacity of rat accessory respiratory muscles to express plasticity is not well known, particularly in unanesthetized animals. Here, we characterized external intercostal (T2, T4, T5, T6, T7, T8, T9 EIC) and abdominal muscle (external oblique and rectus abdominis) electromyogram (EMG) activity in unanesthetized rats via radiotelemetry during normoxia (Nx: 21% O2) and following acute intermi...

    2006-01-01

    The case of a strain injury of the internal oblique abdominal muscle in a professional tennis player is presented. This uncommon lesion resulted from eccentric, unbalanced trunk rotation. Magnetic resonance imaging helped to confirm the diagnosis. Tennis specific core strengthening is crucial for rehabilitation and recurrence prevention.

  20. Control of abdominal and expiratory intercostal muscle activity during vomiting - Role of ventral respiratory group expiratory neurons

    Miller, Alan D.; Tan, L. K.; Suzuki, Ichiro

    1987-01-01

    The role of ventral respiratory group (VRG) expiratory (E) neurons in the control of abdominal and internal intercostal muscle activity during vomiting was investigated in cats. Two series of experiments were performed: in one, the activity of VRG E neurons was recorded during fictive vomiting in cats that were decerebrated, paralyzed, and artificially ventilated; in the second, the abdominal muscle activity during vomiting was compared before and after sectioning the axons of descending VRG E neurons in decerebrate spontaneously breathing cats. The results show that about two-thirds of VRG E neurons that project at least as far caudally as the lower thoracic cord contribute to internal intercostal muscle activity during vomiting. The remaining VRG E neurons contribute to abdominal muscle activation. As shown by severing the axons of the VRG E neurons, other, as yet unidenified, inputs (either descending from the brain stem or arising from spinal reflexes) can also produce abdominal muscle activation.

    MacDonald, David; Wan, Alan; McPhee, Megan; Tucker, Kylie; Hug, François

    2016-04-01

    The aim of this study was to assess the intra-session and inter-rater reliability of shear modulus measured in abdominal muscles during two commonly used trunk stability exercises. Thirty healthy volunteers performed a series of abdominal hollow and abdominal brace tasks. Supersonic shear imaging was used to measure the shear modulus (considered an index of muscle tension) of the four anterior trunk muscles: obliquus externus abdominis, obliquus internus abdominis, transversus abdominis and rectus abdominis. Because of measurement artifacts, internus abdominis and transversus abdominis data were not analyzed for 36.7% and 26.7% of the participants, respectively. These participants exhibited thicker superficial fat layers than the others. For the remaining participants, fair to excellent intra-session and inter-rater reliability was observed with moderate to high intra-class coefficients (0.45-0.97) and low to moderate standard error of measurement values (0.38-3.53 kPa). Reliability values were consistently greater for superficial than for deeper muscles. PMID:26746381

  2. The muscles of the infrapubic abdominal wall of a 6-month-old Crocodylus niloticus (Reptilia: Crocodylia).

    Fechner, R; Schwarz-Wings, D

    2013-06-01

    The muscles of the infrapubic abdominal wall of crocodilians play an important role in their ventilatory mechanism. Yet the anatomy and homology of these muscles is poorly understood. To gain new insights into the anatomy of the crocodilian infrapubic abdominal wall, we dissected a specimen of Crocodylus niloticus. Origin and insertion of the muscles, as well as their arrangement relative to each other was examined in great detail. The findings were compared with those of other crocodilian taxa to detect potential variability of the muscles of interest. The homology of the muscles was studied by comparing the muscles of the crocodilian infrapubic abdominal wall with those of other diapsids. In Crocodylus niloticus, the infrapubic abdominal wall consists of four muscles: Musculus truncocaudalis, M. ischiotruncus, and Mm. rectus abdominis externus and internus. The arrangement of the muscles of the infrapubic abdominal wall of Crocodylus niloticus is consistent with that found in most other crocodilian taxa. In some crocodilian taxa, an additional muscle, M. ischiopubis, is found. In the remaining diapsids, only M. rectus abdominis is present. The crocodilian M. truncocaudalis, M. ischiotruncus and, if present, M. ischiopubis appear to be derivates of M. rectus abdominis; the development of those might be related to the evolution of the unique crocodilian ventilatory mechanism.

    Arab, Amir Massoud; Rasouli, Omid; Amiri, Mohsen; Tahan, Nahid

    2013-01-01

    Background Ultrasound (US) imaging has been considered as a non-invasive technique to measure thickness and estimate relative abdominal muscle activity. Although some studies have assessed the reliability of US imaging, no study has assessed the reliability of US measurement of automatic activity of abdominal muscles in positions with different levels of stability in participants with chronic low back pain (cLBP). The purpose of this study was to investigate within-day and between-days reliab...

    M. Unger

    2010-02-01

    Full Text Available Introduction: A bdominal muscles are key to both posture andgait in both children with typical development (TD and with disabilities.Ultrasound (US imaging is a potential non-invasive method for investigatingactivity in these muscles. This study therefore aimed to determine the inter-tester and intra-tester reliability of B-mode US for investigating transverseabdominus (TrA , rectus abdominus (RA and external- (EO and internaloblique (IO muscle activity in children with TD. Design: A  prospective cor-relational descriptive study.  Participants:  Eighty six, 6-13year old children from one private and one public mainstream school. Outcome measures: Two sets of B-mode US images where captured per subject during rest and during head-up, resisted head-up and resisted sling activities. Intra-class Correlation Coefficients (ICC and standard error of measurement (SEM were used to analyse the data. Results: Good correlation was found for both test - retest condi-tions for all four muscles tested during rest: 0.91(TrA ; 0.90(IO; 0.91(EO; 0.94(RA for intra-tester reliability and0.74(TrA ; 0.88(IO; 0.74(EO; 0.83(RA for inter-tester reliability. Repeatability of thickness measures during activity however showed variation in recruitment patterns. A  significant correlation was found between age and BMI andresting abdominal muscle thickness (p<0.001. Conclusion: The study supports the reliability of US measurement of resting abdominal muscles and of the RA  under active conditions in children aged six to 13. However the stability o measurement of the other muscles under active conditions still needs to be established.

    2016-08-01

    In the present study a computational finite element technique is proposed to simulate the mechanical response of muscles in the abdominal wall. This technique considers the active behavior of the tissue taking into account both collagen and muscle fiber directions. In an attempt to obtain the computational response as close as possible to real muscles, the parameters needed to adjust the mathematical formulation were determined from in vitro experimental tests. Experiments were conducted on male New Zealand White rabbits (2047±34g) and the active properties of three different muscles: Rectus Abdominis, External Oblique and multi-layered samples formed by three muscles (External Oblique, Internal Oblique, and Transversus Abdominis) were characterized. The parameters obtained for each muscle were incorporated into a finite strain formulation to simulate active behavior of muscles incorporating the anisotropy of the tissue. The results show the potential of the model to predict the anisotropic behavior of the tissue associated to fibers and how this influences on the strain, stress and generated force during an isometric contraction.

  7. Abdominal Muscle Activity during Mechanical Ventilation Increases Lung Injury in Severe Acute Respiratory Distress Syndrome.

    Xianming Zhang

    Full Text Available It has proved that muscle paralysis was more protective for injured lung in severe acute respiratory distress syndrome (ARDS, but the precise mechanism is not clear. The purpose of this study was to test the hypothesis that abdominal muscle activity during mechanically ventilation increases lung injury in severe ARDS.Eighteen male Beagles were studied under mechanical ventilation with anesthesia. Severe ARDS was induced by repetitive oleic acid infusion. After lung injury, Beagles were randomly assigned into spontaneous breathing group (BIPAPSB and abdominal muscle paralysis group (BIPAPAP. All groups were ventilated with BIPAP model for 8h, and the high pressure titrated to reached a tidal volume of 6ml/kg, the low pressure was set at 10 cmH2O, with I:E ratio 1:1, and respiratory rate adjusted to a PaCO2 of 35-60 mmHg. Six Beagles without ventilator support comprised the control group. Respiratory variables, end-expiratory volume (EELV and gas exchange were assessed during mechanical ventilation. The levels of Interleukin (IL-6, IL-8 in lung tissue and plasma were measured by qRT-PCR and ELISA respectively. Lung injury scores were determined at end of the experiment.For the comparable ventilator setting, as compared with BIPAPSB group, the BIPAPAP group presented higher EELV (427±47 vs. 366±38 ml and oxygenation index (293±36 vs. 226±31 mmHg, lower levels of IL-6(216.6±48.0 vs. 297.5±71.2 pg/ml and IL-8(246.8±78.2 vs. 357.5±69.3 pg/ml in plasma, and lower express levels of IL-6 mRNA (15.0±3.8 vs. 21.2±3.7 and IL-8 mRNA (18.9±6.8 vs. 29.5±7.9 in lung tissues. In addition, less lung histopathology injury were revealed in the BIPAPAP group (22.5±2.0 vs. 25.2±2.1.Abdominal muscle activity during mechanically ventilation is one of the injurious factors in severe ARDS, so abdominal muscle paralysis might be an effective strategy to minimize ventilator-induce lung injury.

  8. Unilateral agenesis of the abdominal wall musculature: An early muscle deficiency.

    2010-11-01

    Prune-belly sequence (PBS) usually results from early urethral obstruction. In rare cases, PBS seems to be due to a faulty primary development of the parietal mesenchyme leading to underdevelopment of the abdominal wall musculature, and disorganization of the smooth muscles in the urinary tract. We report on two patients with segmental, unilateral wall musculature deficiency associated with homolateral agenesis of ribs. One patient also had hemivertebrae and the other one ipsilateral diaphragmatic eventration and aplasia cutis. This combination of anomalies may represent a localized deficiency in the development of somitic mesoderm mesenchyme during early embryogenesis. PMID:20949627

  9. The difference between standing and sitting in 3 different seat inclinations on abdominal muscle activity and chest and abdominal expansion in woodwind and brass musicians

    Bronwen Jane Ackermann

    2014-08-01

    Full Text Available Wind instrumentalists require a sophisticated functioning of their respiratory system to control their air stream, which provides the power for optimal musical performance. The air supply must be delivered into the instrument in a steady and controlled manner and with enough power by the action of the expiratory musculature to produce the desired level of sound at the correct pitch. It is suggested that playing posture may have an impact on the abdominal muscle activity controlling this expired air, but there is no research on musicians to support this theory. This study evaluated chest and abdominal expansion, via respiratory inductive plethysmography, as well as activation patterns of lower and upper abdominal musculature, using surface electromyography, during performance of a range of typical orchestral repertoire by 113 woodwind and brass players. Each of the five orchestral excerpts was played in one of four randomly allocated postures: standing; sitting flat; sitting inclined forwards; and sitting inclined backwards.Musicians showed a clear preference for playing in standing rather than sitting. In standing, the chest expansion range and maximum values were greater (p<0.01, while the abdominal expansion was less than in all sitting postures (p<0.01. Chest expansion patterns did not vary between the three sitting postures, while abdominal expansion was reduced in the forward inclined posture compared to the other sitting postures (p<0.05. There was no significant variation in abdominal muscle activation between the sitting postures, but the level of activation in sitting was only 2/3 of the significantly higher level observed in standing (p<0.01.This study has demonstrated significant differences in respiratory mechanics between sitting and standing postures in wind musicians during playing of typical orchestral repertoire. Further research is needed to clarify the complex respiratory mechanisms supporting musical performance.

    The objective of the research was to assess the effect of a 4-week-long training program on selected parameters: electromechanical delay (EMD) and amplitude of electromyographic signal (EMG). Fourteen female students of the University School of Physical Education participated in the study. Torques and surface electromyography were evaluated under static conditions. Surface electrodes were glued to both sides of the rectus abdominis (RA), external oblique (EO), and erector spinae (ES) muscles. The 4-week-long program was aimed at strengthening the abdominal muscles and resulted in increased EMD during maximum torque production by flexors of the trunk, increased amplitudes of the signals of the erector spinae ( p = 0.005), and increased EMG amplitude asymmetry of the lower ( p = 0.013) and upper part ( p = 0.006) of the rectus abdominis muscle. In a training program composed of a large number of repetitions of strength exercises, in which the training person uses their own weight as the load (like in exercises such as curl-ups), the process of recruitment of motor units is similar to that found during fatiguing exercises and plyometric training.

    2016-03-01

    Full Text Available Introduction. The aim of the study was to assess final-year physical education (PE students’ knowledge of exercises strengthening the abdominal muscles which are used in the introductory part of a PE lesson. Material and methods. The research involved 467 final-year physical education students. The group examined included undergraduate (Bachelor and postgraduate (Master students from four universities in Poland. A knowledge test with photographs was used to conduct the study. The students completed the knowledge test with one of the authors present. If the students had any questions regarding the exercises included in the test, they were demonstrated by the person in the photographs. The data were analysed using the Mann- Whitney-Wilcoxon test. Kendall’s concordance coefficient was used to assess reliability and measure the agreement between the opinions of a group of experts who were asked to rate the exercises in terms of their safety and effectiveness. The calculations were made with the use of statistical and calculation software (SPSS 9.0 for Windows. An alpha value < 0.05 was accepted as the level of significance of differences between the groups of undergraduate and postgraduate students. Results. Eighty-two participants (17.6% performed the task correctly, selecting all the safe exercises, 139 students (29.8% made one error, while 110 marked all the overloading and ineffective exercises as safe. Conclusions. The students’ knowledge of safe exercises strengthening the abdominal muscles was insufficient. Both undergraduate and postgraduate students demonstrated similar knowledge concerning these exercises.

  13. Changes in muscle strength and pain in response to surgical repair of posterior abdominal wall disruption followed by rehabilitation

    Hemingway, A; Herrington, L; Blower, A

    2003-01-01

    Background: Posterior abdominal wall deficiency (PAWD) is a tear in the external oblique aponeurosis or the conjoint tendon causing a posterior wall defect at the medial end of the inguinal canal. It is often known as sportsman's hernia and is believed to be caused by repetitive stress. Objective: To assess lower limb and abdominal muscle strength of patients with PAWD before intervention compared with matched controls; to evaluate any changes following surgical repair and rehabilitation. Methods: Sixteen subjects were assessed using a questionnaire, isokinetic testing of the lower limb strength, and pressure biofeedback testing of the abdominals. After surgery and a six week rehabilitation programme, the subjects were re-evaluated. A control group were assessed using the same procedure. Results: Quadriceps and hamstrings strength was not affected by this condition. A deficit hip muscle strength was found on the affected limb before surgery, which was significant for the hip flexors (p = 0.05). Before surgery, 87% of the patients compared with 20% of the controls failed the abdominal obliques test. Both the injured and non-injured sides had improved significantly in strength after surgery and rehabilitation. The strength of the abdominal obliques showed the most significant improvement over the course of the rehabilitation programme. Conclusions: Lower limb muscle strength may have been reduced as the result of disuse atrophy or pain inhibition. Abdominal oblique strength was deficient in the injured patients and this compromises rotational control of the pelvis. More sensitive investigations (such as electromyography) are needed to assess the link between abdominal oblique function and groin injury. PMID:12547744

  14. Orientation, anisotropy, clustering, and volume fraction of smooth muscle cells within the wall of porcine abdominal aorta

    Tonar Z.

    2008-11-01

    Full Text Available We analyzed tissue samples of the normal porcine abdominal aorta using stereological assessment of histological sections through the tunica media layer. The results demonstrated that the local volume fraction of smooth muscle cells within tunica media does not differ among samples taken round the circumference of the artery, and that volume fraction can be assessed in sections stained with green trichrome as well as with immunohistochemistry against actin. The distribution of angles between the long axes of nuclei of the smooth muscle cells and the radial direction was different from normal. The profiles of smooth muscle cells were distributed in an isotropic, but an inhomogeneous manner.

    Pilates and resistance exercises are used for lumbar stabilization training. However, it is unclear which exercise is more effective for lumbar stabilization. In our study, we aimed to compare surface muscle activity and deep muscle thickness during relaxation and spinal stabilization exercise in experienced Pilates and resistance exercise instructors. This study is a retrospective case control study set in the Exercise Prescription Laboratory and Sports Medicine Center. The participants included Pilates instructors (mean years of experience, 3.20±1.76; n=10), resistance exercise instructors (mean years of experience, 2.53±0.63; n=10), and controls (n=10). The participants performed 4 different stabilization exercises: abdominal drawing-in maneuver, bridging, roll-up, and one-leg raise. During the stabilization exercises, surface muscle activity was measured with electromyography, whereas deep muscle thickness was measured by ultrasound imaging. During the 4 stabilization exercises, the thickness of the transverse abdominis (TrA) was significantly greater in the Pilates-trained group than the other 2 other groups. The internal oblique (IO) thickness was significantly greater in the Pilates- and resistance-trained group than the control group, during the 4 exercises. However, the surface muscle activities were similar between the groups. Both Pilates and resistance exercise instructors had greater activation of deep muscles, such as the TrA and IO, than the control subjects. Pilates and resistance exercise are both effective for increasing abdominal deep muscle thickness. PMID:26171383

    [Purpose] The trunk muscles frequently become weak after stroke, thus impacting overall activities of daily living. However, activities of daily living items closely related with trunk strength remain unclear. This study aimed to clarify the influence of trunk muscle weakness on activities of daily living items. [Subjects] The subjects were 24 stroke patients who fulfilled the following inclusion criteria: first stroke and the absence of severe paralysis, marked cognitive function deterioration, unilateral spatial neglect or apathy. [Methods] According to abdominal strength, the 24 patients were divided into a nonweakness group and a weakness group. For the assessment, we used the stroke impairment assessment set, the Berg balance scale, a simple test for evaluating hand function, grip strength, and functional independence measure scale scores and the results were compared between the groups. [Results] The Berg balance scale score and scores for dressing, toilet use, transfer to bed, and walk items of the functional independence measure were significantly lower in the weakness group than in the nonweakness group. [Conclusion] Our results suggest that weakness of the abdominal muscles adversely impacts the balance of patients with mild stroke as well as their ability to dress, use a toilet, transfer, and walk. Trunk training, including abdominal muscle exercises, can effectively improve the performance of these activities of daily living items. PMID:25931737

    Full Text Available Background Rectus abdominis muscle and abdominal subcutaneous fat tissue are usefulfor reconstruction of the chest wall, and abdominal, vaginal, and perianal defects. Thus,preoperative evaluation of rectus abdominis muscle and abdominal subcutaneous fat tissue isimportant. This is a retrospective study that measured the thickness of rectus abdominis muscleand abdominal subcutaneous fat tissue using computed tomography (CT and analyzed thecorrelation with the patients’ age, gestational history, history of laparotomy, and body massindex (BMI.Methods A total of 545 adult women were studied. Rectus abdominis muscle and abdominalsubcutaneous fat thicknesses were measured with abdominopelvic CT. The results were analyzedto determine if the thickness of the rectus abdominis muscle or subcutaneous fat tissue wassignificantly correlated with age, number of pregnancies, history of laparotomy, and BMI.Results Rectus abdominis muscle thicknesses were 9.58 mm (right and 9.73 mm (left at thexiphoid level and 10.26 mm (right and 10.26 mm (left at the umbilicus level. Subcutaneousfat thicknesses were 24.31 mm (right and 23.39 mm (left. Rectus abdominismuscle thicknessdecreased with age and pregnancy. History of laparotomy had a significant negative correlationwith rectus abdominis muscle thickness at the xiphoid level. Abdominal subcutaneous fatthickness had no correlation with age, number of pregnancies, or history of laparotomy.Conclusions Age, gestational history, and history of laparotomy influenced rectus abdominismuscle thickness but did not influence abdominal subcutaneous fat thickness. These results areclinically valuable for planning a rectus abdominis muscle flap and safe elevation of muscle flap.

  18. Ultrasound-Derived Abdominal Muscle Thickness Better Detects Metabolic Syndrome Risk in Obese Patients than Skeletal Muscle Index Measured by Dual-Energy X-Ray Absorptiometry.

    Ayumi Ido

    Full Text Available Sarcopenia has never been diagnosed based on site-specific muscle loss, and little is known about the relationship between site-specific muscle loss and metabolic syndrome (MetS risk factors. To this end, this cross-sectional study aimed to investigate the relationship between site-specific muscle size and MetS risk factors. Subjects were 38 obese men and women aged 40-82 years. Total body fat and lean body mass were assessed by whole-body dual-energy X-ray absorptiometry (DXA scan. Muscle thickness (MTH was measured using B-mode ultrasound scanning in six body regions. Subjects were classified into general obesity (GO and sarcopenic obesity (SO groups using the threshold values of one standard deviation below the sex-specific means of either MTH or skeletal muscle index (SMI measured by DXA. MetS risk score was acquired by standardizing and summing the following continuously distributed variables: visceral fat area, mean blood pressure, HbA1c, and serum triglyceride / high density lipoprotein cholesterol, to obtain the Z-score. Multiple regression analysis revealed that the MetS risk score was independently associated with abdominal MTH in all subjects, but not with MTH in other muscle regions, including the thigh. Although HbA1c and the number of MetS risk factors in the SO group were significantly higher than those in the GO group, there were no significant differences between GO and SO groups as defined by SMI. Ultrasound-derived abdominal MTH would allow a better assessment of sarcopenia in obese patients and can be used as an alternative to the conventionally-used SMI measured by DXA.

    2015-02-01

    Full Text Available Background: Low back pain (LBP and urinary incontinence (UI are highly prevalent among elderly individuals. In young adults, changes in trunk muscle recruitment, as assessed via ultrasound imaging, may be associated with lumbar spine stability. Objective: To assess the associations between LBP, UI, and the pattern of transversus abdominis (TrA, internal (IO, and external oblique (EO muscle recruitment in the elderly as evaluated by ultrasound imaging. Method: Fifty-four elderly individuals (mean age: 72±5.2 years who complained of LBP and/or UI as assessed by the McGill Pain Questionnaire, Incontinence Questionnaire-Short Form, and ultrasound imaging were included in the study. The statistical analysis comprised a multiple linear regression model, and a p-value <0.05 was considered significant. Results: The regression models for the TrA, IO, and EO muscle thickness levels explained 2.0% (R2=0.02; F=0.47; p=0.628, 10.6% (R2=0.106; F=3.03; p=0.057, and 10.1% (R2=0.101; F=2.70; p=0.077 of the variability, respectively. None of the regression models developed for the abdominal muscles exhibited statistical significance. A significant and negative association (p=0.018; β=-0.0343 was observed only between UI and IO recruitment. Conclusion: These results suggest that age-related factors may have interfered with the findings of the study, thus emphasizing the need to perform ultrasound imaging-based studies to measure abdominal muscle recruitment in the elderly.

The aim of this study was to assess the relationship between cough-specific quality of life, abdominal muscle endurance, fatigue, and depression in stable patients with COPD.Methods: Twenty-eight patients with COPD (mean age 60.6±8.7 years referred for pulmonary rehabilitation participated in this cross-sectional study. Sit-ups test was used for assessing abdominal muscle endurance. Leicester Cough Questionnare (LCQ was used to evaluate symptom-specific quality of life. Fatigue perception was evaluated with Fatigue Impact Scale (FIS. Beck Depression Inventory (BDI was used for assessing depression level.Results: The LCQ total score was significantly associated with number of sit-ups; BDI score; FIS total; physical, cognitive, and psychosocial scores (P<0.05. Scores of the LCQ physical, social, and psychological domains were also significantly related with number of sit-ups, FIS total score, and BDI score (P<0.05. FIS total score and number of sit-ups explained 58% of the variance in LCQ total score (r=0.76, r2=0.577, F(2–20=12.296, P<0.001.Conclusion: Chronic cough may adversely affect performance in daily life due to its negative effect on fatigue and decrease abdominal muscle endurance in patients with COPD. Decreased cough-related quality of life is related with increased level of depression in COPD patients. Effects of increased abdominal muscle endurance and decreased fatigue in COPD patients with chronic cough need further investigation.Keywords: cough, quality of

    1994-05-01

    Near-IR spectroscopy was used to quantify blood content and oxygenation dynamics in abdominal organs and skeletal muscle of 18 anesthetized rabbits during hypoxic hypoxia. Liver, kidney, and hindlimb muscle were exposed surgically. Laser diode pulses transmitted across the tissues were detected by means of a photomultiplier. The amount and redox level of tissue hemoglobin were estimated from the near-IR signals and monitored during 5- min-long hypoxic challenges and subsequent recovery periods. In the kidney, exposure to 10% FiO2 resulted in rapid and symmetrical changes in oxygenated and reduced hemoglobin with 50% of the variations occurring within 1 min and a plateau after 3 min. Total hemoglobin did not change and hemoglobin oxygenation returned to baseline within 1 min of hypoxia cessation. Exposure to 6% FiO2 doubled the decrease in oxygenated hemoglobin and induced a sustained vasoconstriction which decreased total hemoglobin content 2 min after initiation of hypoxia. Comparable patterns were observed in the liver and skeletal muscle with the following exceptions: local vasoconstriction was generally not observed at 6% FiO2, return to baseline oxygen availability was much slower in skeletal muscle than in the other organs.

    Ultrasound (US) measures are used by clinicians and researchers to evaluate improvements in activity of the abdominal muscles in patients with low back pain. Studies evaluating the reproducibility of these US measures provide some information; however, little is known about the reproducibility of these US measures over time in patients with low back pain. The objectives of this study were to estimate the reproducibility of ultrasound measurements of automatic activation of the lateral abdomin...

  5. Loss of abdominal muscle in Pitx2 mutants associated with altered axial specification of lateral plate mesoderm.

    Diana Eng

    Full Text Available Sequence specific transcription factors (SSTFs combinatorially define cell types during development by forming recursively linked network kernels. Pitx2 expression begins during gastrulation, together with Hox genes, and becomes localized to the abdominal lateral plate mesoderm (LPM before the onset of myogenesis in somites. The somatopleure of Pitx2 null embryos begins to grow abnormally outward before muscle regulatory factors (MRFs or Pitx2 begin expression in the dermomyotome/myotome. Abdominal somites become deformed and stunted as they elongate into the mutant body wall, but maintain normal MRF expression domains. Subsequent loss of abdominal muscles is therefore not due to defects in specification, determination, or commitment of the myogenic lineage. Microarray analysis was used to identify SSTF families whose expression levels change in E10.5 interlimb body wall biopsies. All Hox9-11 paralogs had lower RNA levels in mutants, whereas genes expressed selectively in the hypaxial dermomyotome/myotome and sclerotome had higher RNA levels in mutants. In situ hybridization analyses indicate that Hox gene expression was reduced in parts of the LPM and intermediate mesoderm of mutants. Chromatin occupancy studies conducted on E10.5 interlimb body wall biopsies showed that Pitx2 protein occupied chromatin sites containing conserved bicoid core motifs in the vicinity of Hox 9-11 and MRF genes. Taken together, the data indicate that Pitx2 protein in LPM cells acts, presumably in combination with other SSTFs, to repress gene expression, that are normally expressed in physically adjoining cell types. Pitx2 thereby prevents cells in the interlimb LPM from adopting the stable network kernels that define sclerotomal, dermomyotomal, or myotomal mesenchymal cell types. This mechanism may be viewed either as lineage restriction or specification.

  6. The role of computed tomography in evaluating body composition and the influence of reduced muscle mass on clinical outcome in abdominal malignancy: a systematic review.

    Gibson, D J; Burden, S T; Strauss, B J; Todd, C; Lal, S

    2015-10-01

    It is estimated that there were 3.45 million new cases and 1.75 million deaths from cancer in Europe in 2012. Colorectal cancer was one of the most common cancers, accounting for 13% of new cases and 12.2% of all deaths. Conditions causing reduced muscle mass, such as sarcopenia, can increase the morbidity and mortality of people with cancer. Computed tomography (CT) scans can provide accurate, high-quality information on body composition, including muscle mass. To date, there has been no systematic review on the role of CT scans in identifying sarcopenia in abdominal cancer. This review aimed to examine the role of CT scans in determining the influence of reduced muscle mass on clinical outcome in abdominal cancer. A systematic review of English-language articles published in 2000 or later was conducted. Articles included cohort, randomised controlled trials and validation studies. Participants were people diagnosed with abdominal cancer who had undergone a CT scan. Data extraction and critical appraisal were undertaken. Ten cohort studies met the inclusion criteria. Seven studies demonstrated that low muscle mass was significantly associated with poor clinical outcome, with six specifically demonstrating reduced survival rates. Eight studies demonstrated that a greater number of patients (27.3-66.7%) were identified as sarcopenic using CT scans compared with numbers identified as malnourished using body mass index. CT scans can identify reduced muscle mass and predict negative cancer outcomes in people with abdominal malignancies, where traditional methods of assessment are less effective. PMID:25782424

  7. Postoperative outcomes following preoperative inspiratory muscle training in patients undergoing open cardiothoracic or upper abdominal surgery: protocol for a systematic review

    Mans Christina M

    2012-12-01

    Full Text Available Abstract Background In patients undergoing open cardiothoracic and upper abdominal surgery, postoperative pulmonary complications remain an important cause of postoperative morbidity and mortality, impacting upon hospital length of stay and health care resources. Adequate preoperative respiratory muscle strength may help protect against the development of postoperative pulmonary complications and therefore preoperative inspiratory muscle training has been suggested to be of potential value in improving postoperative outcomes. Methods/Design A systematic search of electronic databases will be undertaken to identify randomized trials of preoperative inspiratory muscle training in patients undergoing elective open cardiothoracic and upper abdominal surgery. From these trials, we will extract available data for a list of predefined outcomes, including postoperative pulmonary complications, hospital length of stay and respiratory muscle strength. We will meta-analyze comparable results where possible, and report a summary of the available pool of evidence. Discussion This review will provide the most comprehensive answer available to the question of whether preoperative inspiratory muscle training is clinically useful in improving postoperative outcomes in patients undergoing cardiothoracic and upper abdominal surgery. It will help inform clinicians working in the surgical arena of the likely effectiveness of instituting preoperative inspiratory muscle training programs to improve postoperative outcomes.

  8. Comparison of the effect of alpha1- and alpha2-adrenoceptor agonists and antagonists on muscle contractility of the rabbit abdominal aorta in vitro.

    2013-01-01

    The aim of the study was to demonstrate the effect of selected agonists and antagonists of alpha-adrenergic receptors on muscle contractility of the rabbit abdominal aorta in vitro with particular emphasis on alpha2-adrenergic receptor subtypes. The study was conducted on 30 New Zealand breed rabbits from which specimens of the abdominal aorta were collected. The sections were set up in an automatic water bath in a Krebs-Henseleit buffer at 37 degrees C. The experiments showed that alpha1-adrenergic receptors played the main role in the contractile response ofthe rabbit abdominal aorta. Stimulation of alpha1-adrenergic receptor by administration ofphenylephrine resulted in an increase in smooth muscle tonus ofthe rabbit abdominal aorta by an average of 4.75 mN. The reaction after stimulation of alpha2-adrenergic receptors by similar doses of their agonists was much weaker. Prolonged tissue response time and time needed to reach maximum tonus for alpha2-adrenergic receptor agonists were observed. The obtained results confirm the thesis that the alpha1-adrenergic receptor is the most important factor controlling the contractility of the rabbit abdominal aorta, but the alpha2-adrenergic receptor is also involved in maintaining muscle tissue tonus.

  9. Respiratory responses to stimulation of abdominal and upper-thorax intercostal muscles using multiple Permaloc® electrodes

    James S. Walter, PhD

    2015-04-01

    Full Text Available Stimulation of abdominal and upper-thoracic muscles was studied with the long-term goal of improved respiratory care for spinal cord injury (SCI patients. A 12-channel stimulator and multiple surface and implanted Permaloc electrodes were evaluated in five anesthetized canines. Abdominal stimulation with 100 mA using four bilateral sets of surface electrodes placed on the midaxillary line at the 7th through 13th intercostal spaces and with a closed airway at a large lung volume produced an expiratory tracheal pressure of 109 +/– 29 cm H2O (n = 2, mean +/– standard error of the mean. Similar high pressures were induced with implanted electrodes at the same locations. Upper-thoracic stimulation with 40 mA and four sets of implanted electrodes ventral to the axilla induced inspiratory pressures of −12 +/– 2 cm H2O (n = 5. Combined extradiaphragmatic pacing with an open airway produced a tidal volume of 440 +/– 45 mL (n = 4. The robust respiratory volumes and pressures suggest applications in SCI respiratory care.

    2016-01-01

    Full Text Available ABSTRACT Background Few studies have explored the effects of stretching techniques on diaphragm and spine kinematics. Objective To determine whether the application of diaphragm stretching resulted in changes in posterior chain muscle kinematics and ribcage and abdominal excursion in healthy subjects. Method Eighty healthy adults were included in this randomized clinical trial. Participants were randomized into two groups: the experimental group, which received a diaphragmatic stretching technique, or the placebo group, which received a sham-ultrasound procedure. The duration of the technique, the position of participants, and the therapist who applied the technique were the same for both treatments. Participant assessment (cervical range of movement, lumbar flexibility, flexibility of the posterior chain, and rib cage and abdominal excursion was performed at baseline and immediately after the intervention by a blinded assessor. Results The mean between-group difference [95% CI] for the ribcage excursion after technique at xiphoid level was 2.48 [0.97 to 3.99], which shows significant differences in this outcome. The remaining between-group analysis showed significant differences in cervical extension, right and left flexion, flexibility of the posterior chain, and ribcage excursion at xiphoid level (p<0.05 in favor of the experimental group.

  12. Mapping quantitative trait loci affecting fatness and breast muscle weight in meat-type chicken lines divergently selected on abdominal fatness

    Neau André

    2006-01-01

    Full Text Available Abstract Quantitative trait loci (QTL for abdominal fatness and breast muscle weight were investigated in a three-generation design performed by inter-crossing two experimental meat-type chicken lines that were divergently selected on abdominal fatness. A total of 585 F2 male offspring from 5 F1 sires and 38 F1 dams were recorded at 8 weeks of age for live body, abdominal fat and breast muscle weights. One hundred-twenty nine microsatellite markers, evenly located throughout the genome and heterozygous for most of the F1 sires, were used for genotyping the F2 birds. In each sire family, those offspring exhibiting the most extreme values for each trait were genotyped. Multipoint QTL analyses using maximum likelihood methods were performed for abdominal fat and breast muscle weights, which were corrected for the effects of 8-week body weight, dam and hatching group. Isolated markers were assessed by analyses of variance. Two significant QTL were identified on chromosomes 1 and 5 with effects of about one within-family residual standard deviation. One breast muscle QTL was identified on GGA1 with an effect of 2.0 within-family residual standard deviation.

    The use of meshes for treatment of hernias continues to draw attention of surgeons and the industry in the search of an ideal prosthesis. The purpose of this work is to use meshes manufactured from bacterial cellulose, evaluate their organic tissue interaction and compare with an expanded polytetrafluorethylene (ePTFE's) prosthesis used to repair acute defect of muscle aponeurotic induced in rats. Forty-five male Wistar rats were classified using the following criteria: (1) surgical repair of acute muscle aponeurotic defect with perforated bacterial cellulose film (PBC; n = 18); (2) compact bacterial cellulose film (CBC; n = 12) and (3) ePTFE; (n = 15). After postoperative period, rectangles (2 × 3 cm) including prosthesis, muscles and peritoneum were collected for biomechanical, histological and stereological analysis. In all cases, the maximum acceptable error probability for rejecting the null hypothesis was 5 %. Between PBC and CBC samples, the variables of strain (P = 0.011) and elasticity (P = 0.035) were statistically different. The same was found between CBC and ePTFE (elasticity, P = 0.000; strain, P = 0.009). PBC differed from CBC for giant cells (P = 0.001) and new blood vessels (P = 0.000). In conclusion, there was biological integration and biomechanical elasticity of PBC; therefore, we think this option should be considered as a new alternative biomaterial for use as a bio prosthesis.

  15. Expiratory activation of abdominal muscle is associated with improved respiratory stability and an increase in minute ventilation in REM epochs of adult rats.

    Andrews, Colin G; Pagliardini, Silvia

    2015-11-01

    Breathing is more vulnerable to apneas and irregular breathing patterns during rapid eye movement (REM) sleep in both humans and rodents. We previously reported that robust and recurrent recruitment of expiratory abdominal (ABD) muscle activity is present in rats during REM epochs despite ongoing REM-induced muscle atonia in skeletal musculature. To develop a further understanding of the characteristics of ABD recruitment during REM epochs and their relationship with breathing patterns and irregularities, we sought to compare REM epochs that displayed ABD muscle recruitment with those that did not, within the same rats. Specifically, we investigated respiratory characteristics that preceded and followed recruitment. We hypothesized that ABD muscle recruitment would be likely to occur following respiratory irregularities and would subsequently contribute to respiratory stability and the maintenance of good ventilation following recruitment. Our data demonstrate that epochs of REM sleep containing ABD recruitments (REM(ABD+)) were characterized by increased respiratory rate variability and increased presence of spontaneous brief central apneas. Within these epochs, respiratory events that displayed ABD muscle activation were preceded by periods of increased respiratory rate variability. Onset of ABD muscle activity increased tidal volume, amplitude of diaphragmatic contractions, and minute ventilation compared with the periods preceding ABD muscle activation. These results show that expiratory muscle activity is more likely recruited when respiration is irregular and its recruitment is subsequently associated with an increase in minute ventilation and a more regular respiratory rhythm.

    Full Text Available Wolfgang Kemmler, Simon von StengelInstitute of Medical Physics, University of Erlangen-Nürnberg, Erlangen, GermanyBackground: The primary aim of this study was to determine the effect of 12 months of whole-body electromyostimulation (WB-EMS exercise on appendicular muscle mass and abdominal fat mass in subjects specifically at risk for sarcopenia and abdominal obesity, but unable or unwilling to exercise conventionally.Methods: Forty-six lean, nonsportive (<60 minutes of exercise per week, elderly women (aged 75 ± 4 years with abdominal obesity according to International Diabetes Federation criteria were randomly assigned to either a WB-EMS group (n=23 which performed 18 minutes of intermittent, bipolar WB-EMS (85 Hz three sessions in 14 days or an "active" control group (n=23. Whole-body and regional body composition was assessed by dual energy X-ray absorptiometry to determine appendicular muscle mass, upper leg muscle mass, abdominal fat mass, and upper leg fat mass. Maximum strength of the leg extensors was determined isometrically by force plates.Results: After 12 months, significant intergroup differences were detected for the primary endpoints of appendicular muscle mass (0.5% ± 2.0% for the WB-EMS group versus −0.8% ± 2.0% for the control group, P=0.025 and abdominal fat mass (−1.2% ± 5.9% for the WB-EMS group versus 2.4% ± 5.8% for the control group, P=0.038. Further, upper leg lean muscle mass changed favorably in the WB-EMS group (0.5% ± 2.5% versus −0.9% ± 1.9%, in the control group, P=0.033, while effects for upper leg fat mass were borderline nonsignificant (−0.8% ± 3.5% for the WB-EMS group versus 1.0% ± 2.6% for the control group, P=0.050. With respect to functional parameters, the effects for leg extensor strength were again significant, with more favorable changes in the WB-EMS group (9.1% ± 11.2% versus 1.0% ± 8.1% in the control group, P=0.010.Conclusion: In summary, WB-EMS showed positive effects on the

    A 45-year-old man presented with vertebral collapse at L5 as an initial manifestation of multiple myeloma and underwent spinal fusion surgery using recombinant human bone morphogenetic protein-2 (rhBMP-2). Subsequent computed tomography (CT) scans and X-rays revealed heterotopic ossification of the left psoas muscle, pelvis, and anterior abdominal wall. While the occurrence of heterotopic ossification has previously been reported when rhBMP-2 has been used for spinal fusion surgery, this case demonstrates that it can occur to a much greater degree than previously seen.

    2011-12-01

    Full Text Available BACKGROUND: During the second stage of labor, the progression of the fetal expulsion depends on many factors related to maternal and fetal parameters, including the voluntary abdominal pushing. OBJECTIVES: This study aimed to correlate the maternal and fetal parameters that may influence the voluntary maternal pushes during the second stage of labor by using surface electromyography. METHODS: The electromyographic activity of the rectus abdominis and external oblique muscles were measured during the second stage of labor in 24 Brazilian pregnant women. The diastasis of the rectus abdominis, the body mass index and the uterine fundal height were analyzed as maternal parameters and the fetal weight, cephalic circumference, APGAR scores and arterial pH and CO2 were analyzed as fetal parameters. The oxytocin usage and the expulsive phase duration were considered. RESULTS: A negative correlation between the rectus abdominis diastasis and the rectus abdomini muscle electromyographic parameters was found (r=-0.407 p=0.04. No statistically significant correlations were found among the rectus abdominis and external oblique muscles electromyography and the other maternal or fetal parameters, as well as among expulsive phase duration and the oxytocin usage. CONCLUSIONS: This study suggests that the rectus abdominis diastasis may be an influential parameter in generating voluntary pushes during the second stage of labor, however it cannot be considered the only necessary parameter for a successful labor.CONTEXTUALIZAÇÃO: Durante o segundo estágio do parto, a progressão da expulsão fetal depende de vários fatores ligados a parâmetros maternos e fetais, dentre eles, o esforço abdominal voluntário.

One hundred and fifty-nine patients (mean age: 13.3 years; range: 6-20 with a body mass index (BMI >90th percentile for age and sex were included. Muscle fat content (MFC was measured in the psoas muscle by proton magnetic resonance spectroscopy. The patients were assigned to two groups: MFC <5% or ³5%. Visceral adipose tissue volume (VAT and subcutaneous adipose tissue volume (SAT were measured by magnetic resonance imaging. Blood samples were obtained from 119 patients, and liver enzyme concentrations and other variables were measured. The data were analysed to detect any associations between MFC and BMI standard deviation scores, VAT and SAT, blood values, and physical activity levels. The mean BMI standard deviation score (SDS was 3.04 (range 1.32-5.02. The mean MFC was 8.9% (range 0.8-46.7, and 118 (74.2% of 159 patients had an MFC ³5%. Children with a high MFC had a higher BMI SDS (P=0.03 and had a higher VAT, but not SAT or SAT/VAT ratio. Both intramyocellular lipid (IMCL and extramyocellular lipid (EMCL content were elevated in patients with an MFC ³5%. Blood values and physical activity levels did not differ between the two groups. Severely obese children and adolescents tend to have a high MFC, which is associated with elevated VAT and IMCL and EMCL content. An increased MFC may be associated with impaired metabolic processes, which may predispose young people to obesity-related complications.

    2016-03-01

    Diagnostic computed tomography (CT) scans provide numerous opportunities for body composition analysis, including quantification of abdominal circumference, abdominal adipose tissues (subcutaneous, visceral, and intermuscular), and skeletal muscle (SM). CT scans are commonly performed for diagnostic purposes in clinical settings, and methods for estimating abdominal circumference and whole-body SM mass from them have been reported. A supine abdominal circumference is a valid measure of waist circumference (WC). The valid correlation between a single cross-sectional CT image (slice) at third lumbar (L3) for abdominal SM and whole-body SM is also well established. Sarcopenia refers to the age-associated decreased in muscle mass and function. A single dimensional definition of sarcopenia using CT images that includes only assessment of low whole-body SM has been validated in clinical populations and significantly associated with negative outcomes. However, despite the availability and precision of SM data from CT scans and the relationship between these measurements and clinical outcomes, they have not become a routine component of clinical nutrition assessment. Lack of time, training, and expense are potential barriers that prevent clinicians from fully embracing this technique. This tutorial presents a systematic, step-by-step guide to quickly quantify abdominal circumference as a proxy for WC and SM using a cross-sectional CT image from a regional diagnostic CT scan for clinical identification of sarcopenia. Multiple software options are available, but this tutorial uses ImageJ, a free public-domain software developed by the National Institutes of Health. PMID:26392166

    On inspiration descent of the diaphragm is opposed by the passive properties of the abdominal wall, the tone of its muscles, and the inertia of the abdominal contents. As a result, intra-abdominal pressure rises and promotes rib cage expansion. In patients with high spinal injury the diaphragm is the most important muscle of inspiration and abdominal wall displacement is more evident than in normal subjects. Abdominal wall compliance has been measured by relating gastric pressure to abdominal...

  16. Abdominal trauma

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

  17. Abdominal trauma

    The potential for multiple intraperitoneal and retroperitoneal organ injuries often makes accurate clinical evaluation of abdominal trauma patients difficult. Additionally, patients may be unresponsive, have unreliable abdominal physical examinations, or have concurrent serious head and cervical spine injuries which delay diagnosis of and attention to abdominal problems. In these situations radiologic abdominal imaging is often requested. To expedite patient evaluation, close cooperation between the emergency physician and the radiologist is essential. It is the clinical stability of the traumatized patient that dictates the extent of radiologic imaging. Life-threatening hypotension, positive peritoneal signs, or clear evidence of penetrating abdominal injury are indications for immediate surgery. Stable patients with signs suggesting intra-abdominal injury will benefit by further radiologic evaluation with appropriate imaging modalities. The selection of an appropriate modality in any one clinical situation depends upon many criteria including accessibility to diagnostic equipment, the sensitivity and specificity of each technique, and the expertise and preference of the attending radiologist. A suggested scheme for evaluating abdominal trauma patients is presented. Most aspects of this evaluation scheme will be discussed in depth

    2016-08-01

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

  20. The abdominal circulatory pump.

    Andrea Aliverti

    Full Text Available Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body plethysmography during contractions of the diaphragm and abdominal muscles. Trunk volume changes with blood shifts, but body volume does not so that the blood volume shifted between trunk and extremities (Vbs is the difference between changes in trunk and body volume. This is so because both trunk and body volume change identically with breathing and gas expansion or compression. During tidal breathing Vbs was 50-75 ml with an ejection fraction of 4-6% and an output of 750-1500 ml/min. Step increases in abdominal pressure resulted in rapid emptying presumably from the liver with a time constant of 0.61+/-0.1SE sec. followed by slower flow from non-hepatic viscera. The filling time constant was 0.57+/-0.09SE sec. Splanchnic emptying shifted up to 650 ml blood. With emptying, the increased hepatic vein flow increases the blood pressure at its entry into the inferior vena cava (IVC and abolishes the pressure gradient producing flow between the femoral vein and the IVC inducing blood pooling in the legs. The findings are important for exercise because the larger the Vbs the greater the perfusion of locomotor muscles. During asystolic cardiac arrest we calculate that appropriate timing of abdominal compression could produce an output of 6 L/min. so that the abdominal circulatory pump might act as an auxiliary heart.

The defect concerned the abdominal muscles and their aponevrotic sheath, but respected the skin. There was no associated malformation. The outcome was favorable after surgery, and the infant is well at the age of 6 months. PMID:18046068

  5. Functional Abdominal Bloating with Distention

    Sullivan, Stephen Norman

    2012-01-01

    Ten to 25% of healthy persons experience bloating. It is particularly common in persons with the irritable bowel syndrome and constipation. While the cause of bloating remains unknown old explanations such as a excessive intestinal gas, exaggerated lumbar lordosis and psychiatric problems have been disproved. New suggestions include recent weight gain, weak or inappropriately relaxed abdominal muscles, an inappropriately contracted diaphragm and retained fluid in loops of distal small bowel. ...

  7. Abdominal trauma

    Radiologic evaluation of abdominal trauma must provide a quick and accurate assessment of the lesions in order to improve the management of the patient. The technique used varies depending on the mechanism of the trauma (blunt trauma or stab wounds) and the hemodynamic status. Radiologic evaluation is usually performed in blunt trauma whereas stab wound trauma is usually explored surgically. The various techniques available are standard radiographs, ultrasonography, computed tomography and arteriography. The role of magnetic resonance imaging in the immediate evaluation is still not well defined. It appears to be useful method in the delayed evaluation of diaphragmatic trauma. Computed tomography is the method most commonly performed in trauma patients. This technique is accurate and allows correct assessment of the lesions. The disadvantages are the radiation induced and the need for a hemo-dynamically stable patient. The aim of the radiologic evaluation is to provide the clinicians with an accurate description of the lesions. It can help in the management of the patient usually in association with clinical and laboratory data. It can also guide interventional procedures (drainage, embolization...). Finally, it allows radiographic follow-up when conservative treatment is performed. (authors). 26 refs., 11 figs., 1 tab

    We report a rare case of huge abdominal desmoid tumour first detected during pregnancy. The patient delivered vaginally and the size of the tumour increased during puerperium for which resection was done. Most of these tumours occur in the abdominal muscles particularly right rectus abdominis, perhaps related to trauma from abdominal stretching and movement. These tumours are known to regress spontaneously after delivery which was not in our case. Subsequent pregnancies do not appear to resul...

  10. Radiologic findings of abdominal wall endometriosis

    To evaluate the imaging findings of abdominal wall endometriosis. In seven of 17 patients with surgically proven endometriosis of the abdominal wall, we retrospectively reviewed the findings of radiologic studies such as abdominal US (n=3), CT (n=4), and MRI (n=1). One patient under went more than one type of imaging, apparently. The surgical history of the seven, and their symptoms and preoperative diagnosis were reviewed, and the size, location, margin and nature of the mass, and the contrast enhancement patterns observed at radiologic studies, were assessed. The chief symptoms were palpable abdominal wall mass (n=5) and lower abdominal pain (n=2) around a surgical scar. Previous surgery included cesarean section (n=5), cesarean section with oophorectomy (n=1) and appendectomy (n=1). Masses were located in the subcutaneous fat layer (n=5) or rectus abdominis muscle (n=2), and their maximum diameter was 2.6 cm. Imaging findings, which correlated closely with the pathologic findings, included a well (n=5) or poorly marginated (n=2) solid mass, with a focal cystic area apparent in two cases. Although imaging findings of abdominal wall endometriosis may not be specific for diagnosis, the presence of a solid abdominal mass in female patients of reproductive age with a history of surgery is a diagnostic pointer

  13. Effect of rectal distension on abdominal girth.

    Marino, B; Ogliari, C; Basilisco, G

    2004-08-01

    It has been postulated that a viscerosomatic reflex activated by gut distension and inhibiting abdominal wall muscle tone may be one of the mechanisms underlying functional abdominal distension. Any demonstration of such a reflex has to take into account the fact that gut distension may increase abdominal girth as a result of volume displacement. As biomechanical and sensory rectal responses vary at different rates of rectal distension, we hypothesized that different rates of rectal distension might reveal different changes in abdominal girth. Abdominal girth was continuously recorded in 14 healthy subjects using a previously validated extensometer. The rectal distensions were made in a randomized order at rates of 100 mL min(-1) or 10 mL min(-1) up to 150 mL, and sham distensions were used as controls. An increase in abdominal girth was observed at the end of both distensions (P

  14. Abdominal MRI in childhood

    MRI provides diagnostic information in multiple abdominal diseases in childhood. Additional information to sonographic findings can be achieved in the diagnosis of abdominal malformation as well as in several inflammatory processes. In childhood cancer imaging MRI is essential at the beginning as well as during therapy to assess response to therapy. Because of radiation protection MRI has to replace CT in abdominal imaging in children. Some technical details have to be considered when children are examined. (orig.)

  15. [Abdominal pregnancy, institutional experience].

    Bonfante Ramírez, E; Bolaños Ancona, R; Simón Pereyra, L; Juárez García, L; García-Benitez, C Q

    1998-07-01

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy. PMID:9737070

    The lateral abdominal wall is comprised of three muscles, each with a different function and orientation. The transversus abdominus, internal oblique, and external oblique muscles span the abdominal cavity between the iliocostalis lumborum and quadratus lumborum posteriorly and the rectus abdominis anteriorly. The lateral abdominal wall is bound superiorly by the lower ribs and costal cartilages and inferiorly by the iliac crest and inguinal ligament. The lateral abdominal wall may be acutely or chronically injured in a variety of athletic endeavors, with occasional acute injuries in the setting of high-energy trauma such as motor vehicle collisions. Injuries to the lateral abdominal wall may result in lumbar hernia formation, unique for its high incarceration rate, and also Spigelian hernias. This article will review the anatomy, the magnetic resonance (MR) imaging approach, and the features and complications of lateral abdominal wall injuries. (orig.)

  8. Childhood abdominal cystic lymphangioma

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two. Conclusions: US

  10. Abdominal Dual Energy Imaging

    Sommer, F. Graham; Brody, William R.; Cassel, Douglas M.; Macovski, Albert

    1981-11-01

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

  11. Abdominal Vascular Catastrophes.

    Singh, Manpreet; Koyfman, Alex; Martinez, Joseph P

    2016-05-01

    Abdominal vascular catastrophes are among the most challenging and time sensitive for emergency practitioners to recognize. Mesenteric ischemia remains a highly lethal entity for which the history and physical examination can be misleading. Laboratory tests are often unhelpful, and appropriate imaging must be quickly obtained. A multidisciplinary approach is required to have a positive impact on mortality rates. Ruptured abdominal aortic aneurysm likewise may present in a cryptic fashion. A specific type of ruptured aneurysm, the aortoenteric fistula, often masquerades as the more common routine gastrointestinal bleed. The astute clinician recognizes that this is a more lethal variant of gastrointestinal hemorrhage. PMID:27133247

  13. Rectus abdominis muscle endometriosis

    Endometriosis is characterized by an abnormal existence of functional endometrial tissue outside the uterine cavity, typically occuring within the pelvis of women in reproductive age. We report two cases with endometriosis of the abdominal wall; the first one in the rectus abdominis muscle and the second one in the surgical scar of previous caesarean incision along with the rectus abdominis muscle. Pre-operative evaluation included magnetic resonance imaging. The masses were dissected free from the surrounding tissue and excised with clear margins. Diagnosis of the excised lesions were verified by histopathology. (author)

  15. Adult abdominal hernias.

    Murphy, Kevin P

    2014-06-01

    Educational Objectives and Key Points. 1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both elective and acute circumstances because of rapid acquisition, capability of multiplanar reconstruction, good spatial resolution, and anatomic depiction with excellent sensitivity for most complications. 3. Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment, whereas MRI is beneficial when there is reasonable concern that a patient\\'s symptoms could be attributable to a hernia or a musculoskeletal source. 4. Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination. 5. The diagnosis of an internal hernia not only is a challenging clinical diagnosis but also can be difficult to diagnose with imaging: Closed-loop small-bowel obstruction and abnormally located bowel loops relative to normally located small bowel or colon should prompt assessment for an internal hernia.

    2014-01-01

    Component separation is established for complex hernia repairs. This case presents early component separation and release of the anterior and posterior sheath to facilitate closure of the abdominal wall following emergency laparotomy, reinforcing the repair with a biological mesh. On Day 11 following an emergency laparotomy for penetrating trauma, this patient underwent component separation and release of the anterior and posterior sheath. An intra-abdominal biological mesh was secured, and the fascia and skin closed successfully. Primary abdominal closure can be achieved in patients with penetrating abdominal trauma with the use of component separation and insertion of intra-abdominal biological mesh, where standard closure is not possible.

  19. CT of abdominal trauma

    Soon after it became available for clinical use, cranial CT became the method of choice for evaluating head trauma. Only relatively recently have newer generation full-body scanners been installed at major trauma centers, but experience is rapidly being gained in the utilization of CT for abdominal trauma. CT has proved highly accurate in diagnosing a wide variety of injuries to both intra- and retroperitoneal organs in pediatric and adult patient populations. The impact has been evident not only in decreasing utilization of other diagnostic tests, such as angiography, but also in practical management decisions, such as whether to perform exploratory laparotomy. This chapter details the authors' approach to evaluation of abdominal trauma by CT

  20. The blunt abdominal trauma

    Up to 1970 the number of patients suffering from blunt abdominal trauma showed a substantial increase. In more than 50% of all cases there are additional injuries. The most important factor influencing the prognosis of these patients is the early and correct indication for operation and the avoidance of unnecessary laparotomies. As a primary aim in diagnosis one should consider the recognition of an intraperitoneal bleeding without risk for the patient. Peritoneal lavage as an invasive method with low complication rates has proved good. First reports also show good results using the sonography of the abdomen. The recognition of the injured organ allows a carefully directed operation. Concerning the prognosis it is of minor importance. The diagnosis in patients with blunt abdominal trauma at the university clinic of Freiburg consists of: sonography, followed in positive cases by laparotomy or angiography and laparotomy. In cases with questionable results a lavage is done. (orig.)

  2. Obesity-Associated Abdominal Elephantiasis

    Ritesh Kohli

    2013-01-01

    Full Text Available Abdominal elephantiasis is a rare entity. Abdominal elephantiasis is an uncommon, but deformative and progressive cutaneous disease caused by chronic lymphedema and recurrent streptococcal or Staphylococcus infections of the abdominal wall. We present 3 cases of patients with morbid obesity who presented to our hospital with abdominal wall swelling, thickening, erythema, and pain. The abdominal wall and legs were edematous, with cobblestone-like, thickened, hyperpigmented, and fissured plaques on the abdomen. Two patients had localised areas of skin erythema, tenderness, and increased warmth. There was purulent drainage from the abdominal wall in one patient. They were managed with antibiotics with some initial improvement. Meticulous skin care and local keratolytic treatment for the lesions were initiated with limited success due to their late presentation. All three patients refused surgical therapy. Conclusion. Early diagnosis is important for the treatment of abdominal elephantiasis and prevention of complications.

  3. Abdominal aspergillosis: CT findings

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

    Background If a chronically infected abdominal wound develops, complications such as peritonitis and an abdominal wall defect could occur. This could prolong the patient's hospital stay and increase the possibility of re-operation or another infection as well. For this reason, a solution for infection control is necessary. In this study, surgery using a rectus abdominis muscle myofascial splitting flap was performed on an abdominal wall defect. Methods From 2009 to 2012, 5 patients who underw...

  10. [Differential diagnosis of abdominal pain].

    Frei, Pascal

    2015-09-01

    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain. PMID:26331201

  12. Hypnosis for functional abdominal pain.

    Gottsegen, David

    2011-07-01

    Chronic abdominal pain is a common pediatric condition affecting 20% of the pediatric population worldwide. Most children with this disorder are found to have no specific organic etiology and are given the diagnosis of functional abdominal pain. Well-designed clinical trials have found hypnotherapy and guided imagery to be the most efficacious treatments for this condition. Hypnotic techniques used for other somatic symptoms are easily adaptable for use with functional abdominal pain. The author discusses 2 contrasting hypnotic approaches to functional abdominal pain and provides implications for further research. These approaches may provide new insights into this common and complex disorder. PMID:21922712

  14. A large abdominal desmoid tumour associated with pregnancy and puerperium

    Setu Rathod

    2014-02-01

    Full Text Available We report a rare case of huge abdominal desmoid tumour first detected during pregnancy. The patient delivered vaginally and the size of the tumour increased during puerperium for which resection was done. Most of these tumours occur in the abdominal muscles particularly right rectus abdominis, perhaps related to trauma from abdominal stretching and movement. These tumours are known to regress spontaneously after delivery which was not in our case. Subsequent pregnancies do not appear to result in recurrence in either FAP (Familial Adenomatous Polyposis or non-FAP patients. It is not clear from currently available data whether pregnancy associated desmoids are molecularly distinct from other desmoids. [Int J Reprod Contracept Obstet Gynecol 2014; 3(1.000: 270-272

  15. Practical pediatric abdominal CT

    This course is designed to help the radiologist in a hospital setting successfully approach abdominal CT in the infant and child. Emphasis is placed on techniques necessary for a high-quality examination of the upper abdomen, as applied to common pediatric problems such as trauma, tumor, and infection. Material is presented on technical considerations, including patient sedation, preparation, and potential pitfalls and helpful hints for imaging. An emphasis is placed on dynamic scanning with table incrementation. The section on trauma focuses on an approach to imaging the abdomen in the injured child, typical injuries, patterns of injury in the upper abdomen, and why CT is the best imaging modality for blunt upper abdominal trauma. The discussion of tumor imaging reviews the appearance of typical childhood neoplasia including Wilms tumor, neuroblastoma, non-Hodgkin and Burkitt lymphoma, and disseminated solid tumors such as rhabdomyosarcoma. The authors emphasize what to look for and where, both on initial and on later (for recurrences) examinations. The discussion of infection addresses detection of abscesses and occult infections in children, as well as imaging of abscesses prior to intervention

  16. Nontraumatic abdominal emergencies: acute abdominal pain: diagnostic strategies

    Marincek, B. [Institute of Diagnostic Radiology, University Hospital Zurich, Raemistrasse 100, 8091 Zurich (Switzerland)

    2002-09-01

    Common causes of acute abdominal pain include appendicitis, cholecystitis, bowel obstruction, urinary colic, perforated peptic ulcer, pancreatitis, diverticulitis, and nonspecific, nonsurgical abdominal pain. The topographic classification of acute abdominal pain (pain in one of the four abdominal quadrants, diffuse abdominal pain, flank or epigastric pain) facilitates the choice of the imaging technique. The initial radiological evaluation often consists of plain abdominal radiography, despite significant diagnostic limitations. The traditional indications for plain films - bowel obstruction, pneumoperitoneum, and the search of ureteral calculi - are questioned by helical computed tomography (CT). Although ultrasonography (US) is in many centers the modality of choice for imaging the gallbladder and the pelvis in children and women of reproductive age, CT is considered to be one of the most valued tools for triaging patients with acute abdominal pain. CT is particularly beneficial in patients with marked obesity, unclear US findings, bowel obstruction, and multiple lesions. The introduction of multidetector row CT (MDCT) has further enhanced the utility of CT in imaging patients with acute abdominal pain. (orig.)

  17. Solução hipersaturada de sal como conservante de pericárdio canino utilizado na reparação do músculo reto abdominal de ratos Wistar Supersaturated salt solution as a canine pericardium preserver used in reparation of the rat rectus abdominis muscle

    Maurício Veloso Brun

    2002-12-01

    Full Text Available Com a finalidade de testar a solução hipersaturada de sal (na proporção de 1,5g de sal comercial para 1m de água tridestilada como conservante, foram realizados implantes de pericárdio canino mantido neste meio, no mínimo por 90 dias, em lesões provocadas no músculo reto abdominal de 24 ratos Wistar. Previamente à implantação da membrana, a solução foi avaliada quanto a presença de bactérias e fungos, demonstrando resultados negativos. Durante o procedimento cirúrgico, foi removido um segmento da largura completa do músculo reto abdominal direito, de 1,5cm de comprimento. A lesão produzida foi preenchida com o implante, sendo este suturado às bordas musculares com fio de náilon monofilamentar 6-0 em padrão contínuo simples. Os animais operados foram subdivididos em seis grupos (I, II, III, IV, V, VI de igual número, sendo posteriormente sacrificados aos três, cinco, sete,10, 15 e 30 dias do pós-operatório, afim de se realizar as avaliações macroscópica e histológica da região do implante. Nos exames macroscópico e histológico pôde-se constatar neovascularização no local reparado, que gradualmente foi decrescendo. Ao exame histológico foi observado a substituição gradativa do implante por tecido conjuntivo fibroso, sem a ocorrência de eliminação do implante ou contaminação. Através destes achados é possível afirmar que a solução hipersaturada de sal estudada, é um meio adequado para a conservação de pericárdio canino.This study evaluates the supersaturated salt solution (1,5g of commercial salt for 1m of tridestilled water as a tissue preserver.

    2005-01-01

    Background: The strength of abdominal muscle and back extensors or their balances are commonly mentioned as major indicators of potential low back pain (LBP). Former studies on anthropometrics in terms of trunk muscle strength seemed to lack precision in methodology. Furthermore, the extension-flexion ratio, which is a good parameter of trunk muscle balance, was not as much studied as simple maximum torques in this area of study.

  19. Cold abscess of the anterior abdominal wall: An unusual primary presentation

    Mohinder Kumar Malhotra

    2012-01-01

    Full Text Available Tuberculosis is considered as ubiquitous disease as it involves any organ, but primary involvement of abdominal muscles is very rare. In most cases, the muscle involvement is secondary and is caused by either hematogenous route or direct inoculation from a tuberculous abdominal lymph node or extension from underlying tubercular synovitis and osteomyelitis. Autopsy studies have shown abdominal wall involvement in less than 1% of patients who died of tuberculosis. Antitubercular therapy is main form of management. Surgical intervention is always secondary in the form of either sonography or computerized tomography-guided aspiration or open drainage which is usually reserved for patients in whom medical treatment has failed. A case is hereby reported about primary tubercular anterior abdominal wall abscess without any evidence of pulmonary, skeletal or gastrointestinal tuberculosis in an apparently healthy individual with any past history of contact or previous antituberculosis therapy.

  20. Abdominal Burkitt lymphoma

    Purpose: As scarce information is available, in this research we have tried to describe the imaging findings of the Burkitt's lymphoma. Retrospective analysis of the clinical and imaging presentation of a 4 years old boy, is given. Biopsy confirmed the BL. Different imaging techniques were combined. The X-rays were negative. The US revealed a moderate hepatomegaly with multiple hypoechoic nodules and free fluid in the abdominal cavity. The CT showed the hepatomegaly as well as solid nodules in great number and different sizes(due to the densitometric behaviour and to post contrast enhancement), a scarce amount of ascites and a density increase of the mesentery fat. The MRI characterized and revealed in detail the US and the CT findings. The Burkitt's lymphoma is a rare entity; several methods are needed to approach the diagnosis. It represents a great clinical and imaging challenge. (author)

  1. Practical human abdominal fat imaging utilizing electrical impedance tomography

    The fundamental cause of metabolic syndrome is thought to be abdominal obesity. Accurate diagnosis of abdominal obesity can be done by an x-ray computed tomography (CT) scan. But CT is expensive, bulky and entails the risks involved with radiation. To overcome such disadvantages, we attempted to develop a measuring device that could apply electrical impedance tomography to abdominal fat imaging. The device has 32 electrodes that can be attached to a subject's abdomen by a pneumatic mechanism. That way, electrode position data can be acquired simultaneously. An applied alternating current of 1.0 mArms was used at a frequency of 500 kHz. Sensed voltage data were carefully filtered to remove noise and processed to satisfy the reciprocal theorem. The image reconstruction software was developed concurrently, applying standard finite element methods and the Marquardt method to solve the mathematical inverse problem. The results of preliminary experiments showed that abdominal subcutaneous fat and the muscle surrounding the viscera could be imaged in humans. While our imaging of visceral fat was not of sufficient quality, it was suggested that we will be able to develop a safe and practical abdominal fat scanner through future improvements

  2. [Endometriosis in the abdominal wall (author's transl)].

    Caligaris, P; Masselot, R; Ducassou, M J; Le Treut, Y; Bricot, R

    1981-01-01

    The authors give 9 case histories of endometriosis localised to the abdominal wall : 3 of them in the umbilicus, 3 in laparotomy incisions (2 of those were Caesareans), 2 of them in the round ligaments at the external opening of the inguinal canal and 1 of them in the right rectus muscle sheath in the abdomen. The functional symptomatology is rhythmical according to menstruation; it is associated with a burning type of pain, a tumour and blood loss. Over and above the theories of aetiology that are now classical, namely tubal retrograde spill, and lymphatic or venous spread, it would seem that prostaglandins and in particular the ratio of P.G.E. divided by P.D.F2 alpha can play a big role. Although Danazol is an effective treatment for endometriosis, the treatment of choice is, in these lesions that are superficial in localisation and easily accessible, to cut them out surgically. This makes it possible on the one hand to look for other intra-abdominal lesions and also on the other hand to confirm the anatomy and pathology (this was done in 7 out of 9 of our cases).

  3. Abdominal-Pelvic Actinomycosis Mimicking Malignant Neoplasm

    Teresa Pusiol

    2011-01-01

    Full Text Available Abdominal-pelvic actinomycosis is often mistaken for other conditions, presenting a preoperative diagnostic challenge. In a 46-year-old female, computed tomography showed an abdominal-pelvic retroperitoneal mass extending from the lower pole of the right kidney to the lower pelvis. The patient had a 3-year history of intrauterine device. The mass appeared to involve the ascending colon, cecum, distal ileum, right Fallopian tube and ovary, and ureter anteriorly and the psoas muscle posteriorly. The resection of retroperitoneal mass, distal ileum appendicectomy, right hemicolectomy, and right salpingo-oophorectomy was performed. The postoperative period was uneventful. Penicillin therapy was given for six months without any complication. The retroperitoneal mass measured 4.5 × 3.5 × 3 cm, surrounded adjacent organs and histologically showed inflammatory granulomatous tissue, agglomeration of filaments, and sulfur granules of Actinomyces, with positive reaction with periodic acid Schiff. Right tubo-ovarian abscess was present. Abdominalpelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intrauterine device.

    A 74-year-old hypertensive woman presented with abdominal discomfort and a pulsatile abdominal mass. Anterior abdominal angiography during cardiac blood pool, and renal scintigraphic imaging demonstrated a large abdominal aortic aneurysm. 1, 2 Before endovascular repair with an aortoiliac endograft, the abdominal aneurysm measured 7.5 x 7.0 cm on abdominal computed tomography. This study demonstrates that a suspected abdominal aortic aneurysm can be confirmed using the addition of anterior abdominal imaging with normal posterior imaging at the time of renal scintigraphy.

    2006-11-01

    Full Text Available Abstract Cough can be associated with many complications. In this article, we present a 59 year old male patient with a very rare combination of a cough related stress fracture of the ninth rib, a traumatic rupture of the diaphragm, and an abdominal wall herniation. The hernia was repaired through surgical treatment without bowel resection, the diaphragm and the internal and oblique abdominal muscle were adapted, and the abdomen was reinforced with a prolene net. Although each individual injury is well documented in the literature, the combination of rib fracture, abdominal herniation and diaphragm rupture has not been reported.

  6. Penetrating abdominal trauma.

    Henneman, P L

    1989-08-01

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

  7. Economics of abdominal wall reconstruction.

    Bower, Curtis; Roth, J Scott

    2013-10-01

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

  12. Updates on abdominal desmoid tumors

    2007-01-01

    Desmoid tumor is a monoclonal, fibroblastic proliferation arising in musculoaponeurotic structures. This connective tissue hyperplasia infiltrates locally, recurs frequentiy after resection but does not metastasize. Abdominal desmoid occurs sporadically, in association with some familial syndromes and often represents a clinical dilemma for surgeons. The enigmatic biology and anatomical location of abdominal desmoids make treatment recommendations difficult. This distinct pathological entity is reviewed with a specific focus on aetiology and management.

    The computer tomographic appearances of lesions of parenchymatous organs following blunt abdominal trauma are described in 13 patients (five liver, four renal, two splenic and two pancreatic injuries). The value of abdominal computer tomography is discussed in relation to the interval between injury and time of abdominal examination and compared with the diagnostic value of abdominal angiography. (orig.)

  16. Detection of abdominal bleeding in blunt abdominal trauma

    Arterial hemorrhage is the most serious immediate complication of blunt abdominal trauma. This paper discusses the detection and localization of active hemorrhage in nonpenetrating injury, as a modification of the technique using technetium-99m sulfur colloid to localize the site of active bleeding in the gastrointestinal tract. Any imaging protocol for suspected hepatosplenic injury can be easily modified to search for active intra-abdominal hemorrhage. The timely detection of unsuspected bleeding improves patient management by allowing the surgeon to reorder his or her treatment priorities. The early detection of clinically unsuspected intra-abdominal, retroperitoneal, or pelvic hemorrhage will identify those patients who may need more definitive diagnostic procedures, interventional angiography for control of bleeding, or surgical intervention. The 500,000-count view of the abdomen and pelvis can be easily incorporated into any existing trauma protocol using technetium-99m sulfur colloid, is of proven value, and adds little additional time to the study

    AIM: To evaluate the clinical, radiological and microbiological properties of abdominal tuberculosis (TB) and to discuss methods needed to get the diagnosis.METHODS: Thirty-one patients diagnosed as abdominal TB between March 1998 and December 2001 at the Gastroenterology Department of Kartal State Hospital,Istanbul, Turkey were evaluated prospectively. Complete physical examination, medical and family history, blood count erythrocyte sedimentation rate, routine biochemical tests,Mantoux skin test, chest X-ray and abdominal ultrasonography (USG) were performed in all cases, whereas microbiological examination of ascites, upper gastrointestinal endoscopy, colonoscopy or barium enema, abdominal tomography, mediastinoscopy, laparoscopy or laparotomy were done when needed.RESULTS: The median age of patients (14 females, 17males) was 34.2 years (range 15-65 years). The most frequent symptoms were abdominal pain and weight loss.Eleven patients had active pulmonary TB. The most common abdominal USG findings were ascites and hepatomegaly. Ascitic fluid analysis performed in 13 patients was found to be exudative and acid resistant bacilli were present in smear and cultured only in one patient with BacTec (3.2 %). Upper gastrointestinal endoscopy yielded nonspecific findings in 16 patients. Colonoscopy performed in 20 patients showed ulcers in 9 (45 %), nodules in 2 (10 %)and, stricture, polypoid lesions, granulomatous findings in terminal ileum and rectal fistula each in one patient (5 %).Laparoscopy on 4 patients showed dilated bowel loops,thickening in the mesentery, multiple ulcers and tubercles on the peritoneum. Patients with abdominal TB were divided into three groups according to the type of involvement.Fifteen patients (48 %) had intestinal TB, L1 patients (35.2 %) had tuberculous peritonitis and 5 (16.8 %)tuberculous lymphadenitis. The diagnosis of abdominal TB was confirmed microbiologically in 5 (16 %) and histopathologically in 19 patients (60.8 %). The

    A 26-years-old Indian male was admitted to hospital with loss of weight and vague abdominal pain of several weeks duration. Ultrasonography and computed tomography showed several expansive lesions near the pancreatic head, probably representing enlarged lymph nodes. A few milliliters of yellowish pus were aspirated by ultrasound guided aspiration. Microscopic examination of the pus showed trophozoits, and mycobacterium tuberculosis subsequently grew from the pus culture. Abdominal tuberculosis is a rare condition, particularly in the pancreas and the peripancreatic region. The report stresses the importance of considering the possible coexistance of more than one infectious disease in patients from endemic areas. 21 refs., 2 figs.

  1. Abdominal radiation causes bacterial translocation

    The purpose of this study was to determine if a single dose of radiation to the rat abdomen leads to bacterial translocation into the mesenteric lymph nodes (MLN). A second issue addressed was whether translocation correlates with anatomic damage to the mucosa. The radiated group (1100 cGy) which received anesthesia also was compared with a control group and a third group which received anesthesia alone but no abdominal radiation. Abdominal radiation lead to 100% positive cultures of MLN between 12 hr and 4 days postradiation. Bacterial translocation was almost nonexistent in the control and anesthesia group. Signs of inflammation and ulceration of the intestinal mucosa were not seen until Day 3 postradiation. Mucosal damage was maximal by Day 4. Bacterial translocation onto the MLN after a single dose of abdominal radiation was not apparently dependent on anatomical, histologic damage of the mucosa

  6. Radiological evaluation of abdominal trauma

    Simple abdomen film has played an important role in decision of emergency operations in patients with the abdominal trauma. Nowadays, it still acts as a primary and inevitable processes in emergency condition. At the Department of Radiology, Hanil Hospital, 70 patients, who were laparotomied due to penetrating or nonpernetraing abdominal trauma, were observed and analyzed with simple abdomen film after comparison with the operative findings. The results are as follows: 1. Most frequent age distribution was 10 to 39 years and marked 70%. Male was in 90% incidence. 2. Penetrating injury largely involved the small bowel and abdominal wall. Non-penetrating injury usually involved the spleen, small bowel, liver, kidney, pancreas, duodenum. 3. Single organ injury occurred in higher incidence at the small bowel and abdominal wall. Multiple organ injury occurred in higher incidence at the spleen, liver, kidney and pancreas. 4. Organ distribution was 26% in spleen, 22% in small bowel, 14% in liver, 11% in abdominal wall. 7% in pancreas, 7% in kidney. 5% in duodenum, 4% in GB and CBD, 2% in diaphragm, 2% in colon, and 1% in stomach. 5. The specific roentgen findings and their frequency which useful in differential diagnosis at abdominal trauma, were as follows: a) flank fluid; Detectable possibility was 71% in liver laceration, 69% in spleen laceration and 57% in pancreas laceration. b) ipsilateral psoas shadow obliteration; Detectable possibility was 57% in liver laceration, 57% in kidney laceration and 46% in spleen laceration. c) free air; Detactable possibility was 60% in duodenal perforation, and 36% in peroration of upper part of small bowel. d) Reflex ileus; Detectable possibility was 64% in small bowel, 50% in liver laceration and 35% in spleen laceration. e) rib fracture; Detactable possibility was 36% in liver laceration and 23% in spleen laceration. f) pleural effusion; Detectable possibility was 29% in liver laceration and 27% in spleen laceration

  7. Avoiding Complications in Abdominal Wall Surgery: A Mathematical Model to Predict the Course of the Motor Innervation of the Rectus Abdominis.

    Ever since its introduction, the transverse rectus abdominis myocutaneous flap has become the mainstay of autologous breast reconstruction. However, concerns regarding donor site morbidity due to the breach of abdominal wall musculature integrity soon followed. Muscle-sparing techniques, eventually eliminating the muscle from the flap all-together with the deep inferior epigastric artery perforator flap, did not eliminate the problem of abdominal wall weakness. This led to the conclusion that motor innervation might be at fault. Studies have shown that even in the presence of an intact rectus abdominis muscle, and an intact anterior rectus sheath, denervation of the rectus abdominis muscle results in significant abdominal wall weakness leading to superior and inferior abdominal bulges, and abdominal herniation. Our aim was to establish a mathematical model to predict the location of the motor innervation to the rectus abdominis muscle, and thus provide surgeons with a tool that will allow them to reduce abdominal morbidity during deep inferior epigastric artery perforator and free muscle-sparing transverse rectus abdominis myocutaneous surgery. We dissected 42 cadaveric hemiabdomens and mapped the course of the thoracolumbar nerves. We then standardized and analyzed our findings and presented them as a relative map which can be adjusted to body type and dimensions. Our dissections show that the motor innervation is closely related to the lateral vascular supply. Thus, when possible, we support the preferred utilization of the medial vascular supply, and the preservation of the lateral supply and motor innervation. PMID:26756600

    Eighty five children with recurrent abdominal pain(RAP) were studied. Organic cause was noticed in 70 cases and non-organic in 15 cases. Giardiasis was the commonest organic cause in 57 (67.0 percent), either alone or with other parasitic infestations. Other organic causes include gallstones (4.7 percent), urinary infections (4.7 percent), esophagitis/gastritis (3.5 percent) and abdominal tuberculosis (2.3 percent). Single parent, school phobia, sibling rivalry, RAP in other family members and nocturnal enuresis are significant factors associated with nonorganic causes PMID:12368527

  9. CT appearances of abdominal tuberculosis

    The purpose of this article is to review and illustrate the spectrum of computed tomography (CT) appearances of abdominal tuberculosis. Tuberculosis can affect any organ or tissue in the abdomen, and can be mistaken for other inflammatory or neoplastic conditions. The most common sites of tuberculosis in the abdomen include lymph nodes, genitourinary tract, peritoneal cavity and gastrointestinal tract. The liver, spleen, biliary tract, pancreas and adrenals are rarely affected, but are more likely in HIV-seropositive patients and in miliary tuberculosis. This article should alert the radiologist to consider abdominal tuberculosis in the correct clinical setting to ensure timely diagnosis and enable appropriate treatment.

    Although the case fatality rate for ectopic pregnancies has decreased to 0.08% in industrialized countries, it still represents 3.8% of maternal mortality in the United States alone. In developing countries, the case fatality rate varies from 3% to 27%. Laparoscopic management of tubal pregnancies is now the standard form of treatment where this technology is available. Abdominal pregnancies are rare, and secondary implantation of tubal ectopic pregnancies is the most common cause of abdominal gestations. We present an interesting case of secondary implantation of a tubal ectopic pregnancy to highlight the appendix as a possible secondary implantation site after a tubal ectopic pregnancy.

    Introduction Negative pressure wound therapy (NPWT) for abdominal surgical site infection (SSI) is becoming increasingly common, although enterocutaneous fistula (ECF) has been reported as a complication. To avoid ECF, we used computed tomography (CT) woundgraphy to evaluate the relationship between the wound and the intestine, and then safely treated the abdominal SSI with NPWT. Case presentation Following a laparoscopic intersphincteric resection for low rectal neuroendocrine tumor and covering ileostomy, a 59-year-old woman underwent stoma closure. Six days after surgery, we diagnosed SSI. We suspected ECF, because the wound was deep and the pus resembled enteric fluid. However, CT woundgraphy showed that the wound was separated from the abdominal cavity and the intestine by the abdominal rectus muscle. Accordingly, we performed NPWT. SSI was cured and the wound was well granulated. Twenty-three days after surgery, the patient was discharged. Eventually, the wound was completely epithelialized. Discussion Although successful NPWT has been reported for open abdominal wounds, ECF is a common complication. ECF can be prevented by separating the wound from the intestine by the omentum or muscle fascia, protecting the intestinal serosa during surgery, and applying low vacuum pressure. The relationships among the wound, the fascia, and the intestine must be evaluated before abdominal SSI treatment. One good method is CT woundgraphy, which evaluates wound extent and depth, closure of muscle fascia, and the relationship between the wound and the intestine. Conclusion We report a case of CT woundgraphy before NPWT for abdominal SSI. CT woundgraphy is a good candidate for evaluating wound condition. PMID:27002290

    1987-02-15

    Pathologically proven 15 cases of abdominal tuberculous mainly located at extraintestinal area during recent 3 years were reviewed retrospectively. The results were as follows: 1. Of total 15 cases were males and 10 cases females. And 7 cases of 15 were among third decades. 2. Total 15 cases of chest x-ray; 4 cases showed pulmonary tuberculous, 2 cases, pleural effusions, and 9 cases, normal, 10 cases of G-I barium study or colonospecic examination showed 2 intestinal tuberculous and 8 normal states. 3. Pattern of abdominal tuberculous mainly located at extraintestinal area according to CT and US findings: 1) 6 cases showed multiple lymphadenopathy on mesentery, paraaortic area, peripancreatic area, gastrohepatic ligament or esophagogastric junction. 2) 6 cases showed abscess formation pattern on inguinal area, retropublic area of abdominal wall, iliopsoas muscle area, abdominal wall and adjacent to IVC at umbilical level. 3) 3 cases showed mesenteric thickening and ascites.

  14. Plain abdominal film and abdominal ultrasound in intestine occlusion

    Plain film of the abdomen is widely used in the diagnostic evaluation of intestinal occlusion. Even though this technique can yield a panoramic and high-resolution view of gas-filled intestinal loops, several factors, such as type and duration of occlusion, neurovascular status of the intestine and general patient condition, may reduce the diagnostic specificy of the plain film relative to the organic or functional nature of the occlusion. From 1987 to 1989, fifty-four patients with intestinal occlusion were studied combining plain abdominal film with abdominal ultrasound (US). This was done in order to evaluate whether the additional information obtained from US could be of value in better determining the nature of the ileus. US evaluation was guided by the information already obtained from plain film which better demonstrates gas-filled loops. The results show that in all 27 cases of dynamic ileus (intestinal ischemia, acute appendicitis, acute cholecistis, acute pancreatitis or blunt abdominal trauma) US demonstrates: intestinal loops slightly increased in caliber, with liquid content, or loops containing rare hyperechoic particles, intestinal wall thickening and no peristalsis. In 27 cases of acute, chronic or complicated mechanical ileus (adhesions, internal hernia, intestinal neoplasm, peritoneal seedings) US shows: 1) in acute occlusion: hyperperistaltic intestinal loops containing inhomogeneous liquid; 2) in chronic occlusion: liquid content with a solid echigenic component; 3) in complicated occlusion: liquid stasis, frequent increase in wall thickness, moderate peritoneal effusion and inefficient peristalsis. In conclusion, based on the obtained data, the authors feel that the combination of plain abdominal film and abdominal US can be useful in the work-up of patient with intestinal occlusion. The information provided by US allows a better definition of the nature of the ileus

    2012-01-01

    Full Text Available Rectus abdominis muscle is one of the rare localizations of endometriosis. In this report, our aim was to present a case in which endometrioma was localized in rectus abdominis muscle. A 33-year old patient who underwent cesarean section six years before, complained of a painful mass measuring 4 cm localized at superior of the right side of incision scar. The mass which was found to be inside of the rectus abdominis muscle was excised totally. There was no relationship between the mass and intra-abdominal viscera and subcutaneous tissue. The result of pathologic examination was endometriosis. Endometrioma should be considered at differential diagnosis of abdominal wall mass in women during reproductive age especially if there is a past history of surgical intervention and shows variations according to menstrual cycle.

  16. Dehydration related abdominal pain (drap)

    Objective: To describe the frequency of dehydration as a medical cause of acute abdomen. Subjects and Methods: All the patients reporting with abdominal pain to the surgical outpatient department or the emergency department were reviewed in the study. The clinical findings in all these cases were studied along with the mode of their management and outcome. Results: Of all the patients presenting with abdominal pain, 3.3% (n=68) were suffering from dehydration related abdominal pain. They were predominantly males in a ratio of 8.7: 1, mostly in the 2nd and 3rd decades of their lives. All these cases were suffering from acute or chronic dehydration were provisionally diagnosed by general practitioners as 'acute abdomen' and referred for surgical consultation. Associated symptoms included vomiting in 42.6%, backache in 91.2%, headache in 95.6%, and pain in lower limbs in 97.1 % of the cases. 83.8% required indoor management with intravenous fluids. All the patients became asymptomatic with rehydration therapy. Conclusion: Dehydration is a possible cause of severe abdominal pain. There is a need to educate the general public about the benefits of adequate fluid intake. (author)

    Full Text Available Objective: To analyze the electromyographic activity of the lower abdominal muscle and thigh adductor, on terrestrial and aquatic activities with women and men's indoor soccer players. Method: For this research, 30 athletes were tested, 15 males and 15 females. The electric activity of the two muscles was recorded by a surface electromyography. The statistical softwares, Matlab and Prisma, were used to determine differences between the values of RMS of each muscle and on each exercise, normalized by the maximum volunteer isotonic contraction. Results: The results show that the lower abdominal muscle presented less electromyographic activity on both groups; while the thigh adductor muscle showed a greater electromyographic activity on both groups in the aquatic environment during the kick movement. Conclusion: It was verified that the kick movement in aquatic environment causes a greater electric activity of the muscle, besides it helps to prevent lesions in articulations, muscles and tendons.

    We present a rare case of intrahepatic cholangiocarcinoma (ICC) with multiple skeletal muscle metastases. The patient was a 55-year-old Asian woman presenting with abdominal pain; abdominal and pelvic computed tomography and magnetic resonance cholangiopancreatography revealed an unresectable ICC with hepatic metastasis and metastastatic lymphadenopathy in the porto-caval area. After 3 mo of treatment with palliative radiotherapy and chemotherapy, magnetic resonance imaging of the thoracolumbar spine detected right psoas muscle and paraspinous muscle metastases. We performed an ultrasound-guided percutaneous fine-needle biopsy that confirmed a similar pattern of poorly differentiated adenocarcinoma. The patient treated with palliative chemotherapy and achieved 10 mo of survival. Here we report the first case quickly spread to multiple sites of muscle even though the three-month treatment, compare to the other cases reported muscle metastases at diagnosis. PMID:25684968

  9. Abdominal fat reducing outcome of exercise training: fat burning or hydrocarbon source redistribution?

    Kuo, Chia-Hua; Harris, M Brennan

    2016-07-01

    Fat burning, defined by fatty acid oxidation into carbon dioxide, is the most described hypothesis to explain the actual abdominal fat reducing outcome of exercise training. This hypothesis is strengthened by evidence of increased whole-body lipolysis during exercise. As a result, aerobic training is widely recommended for obesity management. This intuition raises several paradoxes: first, both aerobic and resistance exercise training do not actually elevate 24 h fat oxidation, according to data from chamber-based indirect calorimetry. Second, anaerobic high-intensity intermittent training produces greater abdominal fat reduction than continuous aerobic training at similar amounts of energy expenditure. Third, significant body fat reduction in athletes occurs when oxygen supply decreases to inhibit fat burning during altitude-induced hypoxia exposure at the same training volume. Lack of oxygen increases post-meal blood distribution to human skeletal muscle, suggesting that shifting the postprandial hydrocarbons towards skeletal muscle away from adipose tissue might be more important than fat burning in decreasing abdominal fat. Creating a negative energy balance in fat cells due to competition of skeletal muscle for circulating hydrocarbon sources may be a better model to explain the abdominal fat reducing outcome of exercise than the fat-burning model.

  11. Intestinal contrasting in abdominal CT

    In 56 patients undergoing abdominal CT the gastro-intestinal tract was defined by negative contrast instead of the conventional positive contrast from an iodine containing contrast medium. The contrast material was a 2 1/2% mannitol solution and was used for filling the rectum. Filling of the gastro-intestinal tract was of similar quality to that obtained with positve contrast media. The number of artifacts due to high contrast boundaries was slightly greater with the negative contrast than if would have been with positive contrast. Differentiation of the gastro-intestinal tract from other abdominal organs was equally good for both methods. The negative contrast method was poor in diagnosing cystic tumours but proved much better than positive contrast for evaluating the wall of the gastro-intestinal tract. (orig.)

  12. Sonography of blunt abdominal trauma

    Sonographic examination of the abdomen after blunt abdominal trauma represents a rapid and effective diagnostic method without bothering the patient. It has proved its value not only in the confirmation or exclusion of free fluid in the abdomen caused by liver of spleen rupture, but also in such cases actually it replaces peritoneal lavage or exploratory laparotomy. It is also qualified for diagnosis of intraparenchymal or subcapsular hemorrhages, intraperitoneal as well as retroperitoneal and for follow up. In particualr delayed bleedings including the risk of a retarded organ rupture can be detected early. A failure rate of 1.4% in 282 sonographically examined cases of blunt abdominal trauma further confirms the reliability of this method. (orig.)

    The intra-abdominal pressure (IAP) measurement is a key to diagnosing and managing critically ill medical and surgical patients. There are an increasing number of techniques that allow us to measure the IAP at the bedside. This paper reviews these techniques. IAP should be measured at end-expiration, with the patient in the supine position and ensuring that there is no abdominal muscle activity. The intravesicular IAP measurement is convenient and considered the gold standard. The level where the mid-axillary line crosses the iliac crest is the recommended zero reference for the transvesicular IAP measurement; moreover, marking this level on the patient increases reproducibility. Protocols for IAP measurement should be developed for each ICU based on the locally available tools and equipment. IAP measurement techniques are safe, reproducible and accurate and do not increase the risk of urinary tract infection. Continuous IAP measurement may offer benefits in specific situations in the future. In conclusion, the IAP measurement is a reliable and essential adjunct to the management of patients at risk of intra-abdominal hypertension. PMID:25973661

  14. CT of abdominal blunt trauma

    We studied CT findings and interventional radiology including therapeutic procedures in 43 cases with abdominal blunt trauma, retrospectively. All of parenchymal organ's injuries, and injuries of duodenum and retroperitoneum were correctly diagnosed by CT. In 14 cases with only hemoperitoneum or no positive findings on CT, 4 cases were jejunal perforations, and remaining 10 cases were conservatively treated and relieved. We have to take care that the similar CT findings include the opposite results to need surgery and not. (author)

  15. [A case of abdominal wall actinomycosis].

    2015-04-01

    Actinomycosis is a chronic suppurative granulomatous infectious disease caused by actinomyces species that is characterized by formation of characteristic clumps called as sulfur granules. Abdominal actinomycosis is a rare disease and is often difficult to diagnose before operation. Abdominal actinomycosis infiltrating into the abdominal wall and adhering to the colon is even rarer. Most abdominal actinomycosis develops after operation, trauma or inflammatory bowel disease, and is also considered as an opportunistic infection in immunocompromised patient with underlying malignancy, diabetes mellitus, human immunodeficiency virus infection, etc. Actinomycosis is diagnosed based on histologic demonstration of sulfur granules in surgically resected specimen or pus, and treatment consists of long-term penicillin based antibiotics therapy with or without surgical resection. Herein, we report an unusual case of abdominal wall actinomycosis which developed in a patient after acupuncture and presented as abdominal wall mass that was first mistaken for abdominal wall invasion of diverticulum perforation.

    2015-12-01

    Full Text Available Zachary F Williams, William W Hope Department of Surgery, South East Area Health Education Center, New Hanover Regional Medical Center, Wilmington, NC, USA Abstract: This review examines both early and late wound complications following laparotomy closure, with particular emphasis on technical aspects that reduce hernia formation. Abdominal fascial closure is an area of considerable variation within the field of general surgery. The formation of hernias following abdominal wall incisions continues to be a challenging problem. Ventral hernia repairs are among the most common surgeries performed by general surgeons, and despite many technical advances in the field, incisional hernia rates remain high. Much attention and research has been directed to the surgical management of hernias. Less focus has been placed on prevention of hernia formation despite its obvious importance. This review examines the effects of factors such as the type of incision, suture type and size, closure method, patient risk factors, and the use of prophylactic mesh. Keywords: incisional, abdominal, hernia, prevention, wound closure techniques 

  17. Acute Abdominal Pain in Children.

    Reust, Carin E; Williams, Amy

    2016-05-15

    Acute abdominal pain accounts for approximately 9% of childhood primary care office visits. Symptoms and signs that increase the likelihood of a surgical cause for pain include fever, bilious vomiting, bloody diarrhea, absent bowel sounds, voluntary guarding, rigidity, and rebound tenderness. The age of the child can help focus the differential diagnosis. In infants and toddlers, clinicians should consider congenital anomalies and other causes, including malrotation, hernias, Meckel diverticulum, or intussusception. In school-aged children, constipation and infectious causes of pain, such as gastroenteritis, colitis, respiratory infections, and urinary tract infections, are more common. In female adolescents, clinicians should consider pelvic inflammatory disease, pregnancy, ruptured ovarian cysts, or ovarian torsion. Initial laboratory tests include complete blood count, erythrocyte sedimentation rate or C-reactive protein, urinalysis, and a pregnancy test. Abdominal radiography can be used to diagnose constipation or obstruction. Ultrasonography is the initial choice in children for the diagnosis of cholecystitis, pancreatitis, ovarian cyst, ovarian or testicular torsion, pelvic inflammatory disease, pregnancy-related pathology, and appendicitis. Appendicitis is the most common cause of acute abdominal pain requiring surgery, with a peak incidence during adolescence. When the appendix is not clearly visible on ultrasonography, computed tomography or magnetic resonance imaging can be used to confirm the diagnosis. PMID:27175718

  18. Treatment of Abdominal Segmental Hernia, Constipation, and Pain Following Herpes Zoster with Paravertebral Block.

    Kim, Saeyoung; Jeon, Younghoon

    2015-01-01

    Herpes zoster (HZ) most commonly occurs in elderly patients and involves sensory neurons resulting in pain and sensory changes. Clinically significant motor deficits and visceral neuropathies are thought to be relatively rare. A 72-year-old man presented with abdominal segmental hernia, constipation, and pain following HZ in the left T9-10 dermatome. Sixteen days before presentation, he had developed a painful herpetic rash in the left upper abdominal quadrant. Approximately 10 days after the onset of the rash, constipation occurred and was managed with daily oral medication with bisacodyl 5 mg. In addition, 14 days after the onset of HZ, the patient noticed a protrusion of the left upper abdominal wall. Abdominal x-ray, ultrasound of the abdomen, and electrolyte analysis showed no abnormalities. General physical examination revealed a reducible bulge in his left upper quadrant and superficial abdominal reflexes were diminished in the affected region. Electromyographic testing revealed denervational changes limited to the left thoracic paraspinal muscles and supraumbilical muscles, corresponding to the affected dermatomes. He was prescribed with 500 mg of famciclovir 3 times a day for 7 days, and pregabalin 75 mg twice a day and acetaminophen 650 mg 3 times a day for 14 days. However, his pain was rated at an intensity of 5 on the numerical analogue scale from 0 (no pain) to 10 (worst pain imaginable). A paravertebral block was performed at T9-10 with a mixture of 0.5% lidocaine 3 mL and triamcinolone 40 mg. One day after the procedure, the abdominal pain disappeared. In addition, 5 days after the intervention, the abdominal protrusion and constipation were resolved. He currently remains symptom free at a 6 month follow-up. PMID:26431148

    Apart from its role as a flow generator for ventilation the diaphragm has a circulatory role. The cyclical abdominal pressure variations from its contractions cause swings in venous return from the splanchnic venous circulation. During exercise the action of the abdominal muscles may enhance this circulatory function of the diaphragm. Eleven healthy subjects (25 ± 7 year, 70 ± 11 kg, 1.78 ± 0.1 m, 3 F) performed plantar flexion exercise at ~4 METs. Changes in body volume (ΔVb) and trunk ...

    Full Text Available Abstract Background Treatment of a number of complications that occur after abdominal surgeries may require that Urgent Abdominal Re-explorations (UARs, the life-saving and obligatory operations, are performed. The objectives of this study were to evaluate the reasons for performing UARs, outcomes of relaparotomies (RLs and factors that affect mortality. Methods Demographic characteristics; initial diagnoses; information from and complications of the first surgery received; durations and outcomes of UAR(s performed in patients who received early RLs because of complicated abdominal surgeries in our clinic between 01.01.2000 and 31.12.2004 were investigated retrospectively. Statistical analyses were done using the chi-square and Fisher exact tests. Results Early UAR was performed in 81 out of 4410 cases (1.8%. Average patient age was 50.46 (13–81 years with a male-to-female ratio of 60/21. Fifty one (62.96% patients had infection, 41 (50.61% of them had an accompanying serious disease, 24 (29.62% of them had various tumors and 57 (70.37% patients were operated under emergency conditions during first operation. Causes of urgent abdominal re-explorations were as follows: leakage from intestinal repair site or from anostomosis (n:34; 41.97%; hemorrhage (n:15; 18.51%; intestinal perforation (n:8; 9.87%; intraabdominal infection or abscess (n:8; 9.87%; progressive intestinal necrosis (n:7; 8.64%; stomal complications (n:5; 6.17%; and postoperative ileus (n:4; 4.93%. Two or more UARs were performed in 18 (22.22% cases, and overall mortality was 34.97% (n:30. Interval between the first laparotomy and UAR averaged as 6.95 (1–20 days, and average hospitalization period was 27.1 (3–78 days. Mortality rate was found to be higher among the patients who received multiple UARs. The most common (55.5% cause of mortality was sepsis/multiple organ failure (MOF.

The disease has no relation with antecedents of previous surgery or trauma and is asociated with a dyasthasis of the rectus abdomini muscles which has conditionated a intestinal evisceration.This evisceration is accommodated in the abdominal apron and is associated with a great accumulation of fluid (liquid in the interstitium, which seems a linphedema. Taking account the combination of liquid and soft tissues the resection is larger than 60 Kg. and this has forced us to develop new strategies for the menagement of the patient and techniques for the reconstruction of the abdominal wall defect.

    Full Text Available Extrauterine abdominal pregnancy is extremely rare and is frequently missed during antenatal care, despite the routine use of obstetrics ultrasound. A 23 year old primigravida at 39 weeks of gestation was admitted to the department on December 2 , 2012, in routine hour with transverse lie with oligohydramnios. On examination her vitals and laboratory investigation were within normal limits . One of the ultrasonographic scanning done by radiologist at 35 wk. 3 days gestation demonstrated a single live intrauterine fetus of CGA 33 wk. 1 day with transverse lie , fundal gr II placenta and AFI - 10 cm. Ultrasonography done at the department on the day of admission demonstrated single live intrauterine fetus with transverse lie and AFI - 3.8 cm and EFW 2.4 Kg and placenta was right anterior.. She was planned for elective caesarean section on account of transverse lie and oligohydramnios at term. At laparotomy the following findings were made: Secondary abdominal pregnancy arising from right tubal ectopic rupture and making pseudogesta tional sac with meconium stained liquor. Omentum , right tube and ovary were adhered to sac. The uterus and left tube and ovary were healthy and normal . Other abdominal organs were normal. A 1.5 Kg live male baby with good Apgar score and incompletely formed mandible extracted from pseudo gestational sac. There was significant bleeding from pseudogestational sac and patient went in shock during intraoperative period. One unit whole blood transfused during intraoperative period. Placenta was adherent to the pseudogestational sac so Psudogestational sac was removed with placenta in situ and right sided salpingo - o ophrectomy was also done due to their adherence.

    Abdominal Aortic Aneurysm (AAA) is a common disease with a prevalence of 1.5-2.0% in 65-year old men in Sweden. The risk of having AAA is increased with smoking, high age, family history of AAA and cardiovascular disease. Women have a lower prevalence (0.5%) and develop AAA later in life. An AAA seldom gives any symptom prior to rupture. Untreated rupture is associated with 100% mortality, while surgically treated rupture is associated with 25-70% mortality. Prophylactic sur...

  6. Radiography of the abdominal cavity

    Radiography is a very important part of the diagnostic procedure in many small animal diseases. Technically perfect X-rays are essential for the exact diagnosis. The general appearance of the abdominal cavity should be evaluated at first, e.g. the overall contrast and the definition of the visualized organs. Then particular attention should be paid, if there is any peritoneal effusion or free air in the peritoneal cavity. Subsequently each radiographically visible organ has to be evaluated for its position, size, shape and radiographic density

  7. Abdominal manifestations of autoimmune disorders

    Full text: Immunoglobulin G4-related disease was recognized as a systemic disease since various extrapancreatic lesions were observed in patients with autoimmune pancreatitis (AIP). The real etiology and pathogenesis of IgG4-RD is still not clearly understood. Moreover the exact role of IgG4 or IgG4-positive plasma cells in this disease has not yet been elucidated. only some inconsistent biological features such as hypergammaglobulinemia or hypocomplementemia support the autoimmune nature of the disease process. various names have been ascribed to this clinicopathological entity including IgG4-related sclerosing disease, IgG4-related systemic sclerosing disease, IgG4-related disease, IgG4-related autoimmune disease, hyper-IgG4 disease and IgG4-related systemic disease. The extrapancreatic lesions of IgG4-RD also exhibit the same characteristic histologic features including dense lymphoplasmacytic infiltrate, massive storiform fibrosis, and obliterative phlebitis as seen in IgG4-related pancreatitis. Abdominal manifestations include the following organs/systems: Bile ducts: Sclerosing cholangitis; Gallbladder and liver: Acalculous sclerosis cholecytitis with diffuse wall thickening; hepatic inflammatory pseudotumorts; Kidneys: round or wedge-shaped renal cortical nodules, peripheral cortical; lesions, mass like lesions or renal pelvic involvement; Prostate, urethra, seminal vesicle, vas deferens, uterine cervix; Autoimmune prostatitis; Retroperitoneum: Retroperitoneal fibrosis. thin or mildly thick homogeneous soft tissue lesion surrounding the abdominal aorta and its branches but also bulky masses causing hydronephroureterosis; Mesentery: Sclerosing mesenteritis usually involving the root of the mesentery; Bowel: Inflammatory bowel diseases mimicking Crohn’s disease or ulcerative colitis. various types of sclerosing nodular lesions of the bowel wall; Stomach: Gastritis, gastric ulcers and focal masses mimicking submucosal tumor; omentum: Infiltration mimicking

    Abstract: During insufflation of the abdomen to create a pneumoperitoneum for laparoscopy, both intra abdominal pressure and insufflated volume can be measured and are used to calculate the abdominal pressure-volume relationship. First, an accurate, linear relationship was identified using a mathematical model with an elastance, E, or its reciprocal the compliance C and with a pressure at zero volume, PV0. This function was stable and could be used to describe the abdominal characteristics of...

  10. Cell death regulates muscle fiber number.

    Sarkissian, Tatevik; Arya, Richa; Gyonjyan, Seda; Taylor, Barbara; White, Kristin

    2016-07-01

    Cell death can have both cell autonomous and non-autonomous roles in normal development. Previous studies have shown that the central cell death regulators grim and reaper are required for the developmentally important elimination of stem cells and neurons in the developing central nervous system (CNS). Here we show that cell death in the nervous system is also required for normal muscle development. In the absence of grim and reaper, there is an increase in the number of fibers in the ventral abdominal muscles in the Drosophila adult. This phenotype can be partially recapitulated by inhibition of cell death specifically in the CNS, indicating a non-autonomous role for neuronal death in limiting muscle fiber number. We also show that FGFs produced in the cell death defective nervous system are required for the increase in muscle fiber number. Cell death in the muscle lineage during pupal stages also plays a role in specifying fiber number. Our work suggests that FGFs from the CNS act as a survival signal for muscle founder cells. Thus, proper muscle fiber specification requires cell death in both the nervous system and in the developing muscle itself. PMID:27131625

In the early literature, abdominal migraine is included in the "childhood periodic syndrome", first described by Wyllie and Schlesinger in 1933. Abdominal migraine has emerged over the last century as a diagnostic entity in its own right thanks to the development of well defined diagnostic criteria and its recent inclusion in the International Headache Society's Classification of Headache disorders. Despite this progress, little is known about the pathophysiology of the condition, and the treatment options are poorly defined. Here we summarize the recent literature, with particular focus on establishing the diagnosis of abdominal migraine and its pathophysiology, and suggest an approach to management.

  13. Anterior Abdominal Wall Leiomyoma Arising De Novo in a Perimenopausal Woman

    Hamed A. Al-Wadaani

    2012-07-01

    Full Text Available Extrauterine or extraintestinal leiomyomas are extremely uncommon especially in the pre-peritoneal area or within the anterior abdominal wall muscles. These tumors have been ascribed to intraoperative seeding during resection of a fibroid or a leiomyoma of gut, to exogenous hormone replacement therapy or a major derangement of glucose and/or lipid metabolism. So far, there is no published report of de novo origin of anterior abdominal wall pure leiomyoma in the literature. The author herein reports a case of perimenopausal multiparous woman without any listing of previous gynecological surgery or hormone therapy who presented with a large pre-peritoneal intramuscular leiomyoma of the anterior abdominal wall. The patient underwent complete primary resection with amelioration of her symptoms.

  14. Percutaneous drainage of abdominal abcess

    Men, Sueleyman E-mail: suleyman.men@deu.edu.tr; Akhan, Okan; Koeroglu, Mert

    2002-09-01

    The mortality in undrained abdominal abscesses is high with a mortality rate ranging between 45 and 100%. The outcome in abdominal abscesses, however, has improved due to advances in image guided percutaneous interventional techniques. The main indications for the catheter drainage include treatment or palliation of sepsis associated with an infected fluid collection, and alleviation of the symptoms that may be caused by fluid collections by virtue of their size, like pancreatic pseudocele or lymphocele. The single liver abscesses may be drained with ultrasound guidance only, whereas the multiple abscesses usually require computed tomography (CT) guidance and placement of multiple catheters. The pancreatic abscesses are generally drained routinely and urgently. Non-infected pancreatic pseudocysts may be simply observed unless they are symptomatic or cause problems such as pain or obstruction of the biliary or the gastrointestinal tract. Percutaneous routes that have been described to drain pelvic abscesses include transrectal or transvaginal approach with sonographic guidance, a transgluteal, paracoccygeal-infragluteal, or perineal approach through the greater sciatic foramen with CT guidance. Both the renal and the perirenal abscesses are amenable to percutaneous drainage. Percutaneous drainage provides an effective and safe alternative to more invasive surgical drainage in most patients with psoas abscesses as well.

  15. Abdominal ultrasound in AIDS patients

    To analyze the ultrasonography findings in abdomen in the AIDS patients in our hospital, as well as the indications for this exploration, assessing the role of abdominal ultrasound (AU). The ultrasonographic and clinical findings in 527 patients who underwent a total of 715 explorations between 1992 and 1996 were studied. Hepatomegaly and/or splenomegaly, usually homogeneous, were observed in nearly half of the studies (45%); one third of the patients with marked splenomegaly presented visceral leishmaniasis. Focal lesions in liver and/or spleen, corresponding to angiomas, abscesses, lymphomatous lesions and metastasis, were detected in 5.7% of the explorations. Thirty-five percent of the AU revealed the presence of lymphadenopathy; nodes measuring over 2.5 cm were usually related to potential treatable infection or neoplasm. Thickening of the gallbladder wall did not usually indicate the presence of acute cholecystitis unless Murphy''s sign was also detected. Bile duct dilation and wall thickening was related to opportunistic cholangitis, and the increase in the echogenicity of the renal parenchyma was linked to AIDS-related nephropathy. Despite the fact that many of findings with AU are nonspecific, we consider that this approach should be the principal diagnostic technique in AIDS patients with suspected abdominal pathology or fever of unknown origin.

    Full Text Available Neonatal abdominal masses have broad spectrum of pathology, ranging from small lesions found incidentally to large masses occupying the entire of peritoneal cavity. These tumors are benign to malignant, and from unilocular cysts to complex solid lesions. Many of these lesions identified and will treat before delivery. Others are discovered during routine examination. These lesions may be life threatening, or cause persistent morbidity. Some of these have no sequel."nDiagnosis began with history. Characteristic of the mass which must be note include location, size, shape, texture, mobility and tenderness. Other findings should be in mind to find out nature of mass, for example hypoplasia of chest wall with oligohydramnios due to GU tract obstruction (potter sequwnce, a bulging hymen due to hydrometrocolpus, skin metastasis due to neuroblastoma. Radiography is the next step that shows organomegaly and calcification. Next step is US which is an excellent screening tool. CT and MRI are occasionally indicated."nThe purpose of this presentation is to review the diagnosis of abdominal masses in neonates.

  17. Predictive Factors in the Outcome of Surgical Repair of Abdominal Rectus Diastasis

    Clay, Leonard; Stark, Birgit; Gunnarsson, Ulf

    2016-01-01

    Background: The aim of this study was to define the indicators predicting improved abdominal wall function after surgical repair of abdominal rectus diastasis (ARD). Preoperative subjective assessment quantified by the validated Ventral Hernia Pain Questionnaire (VHPQ) was related to relative postoperative functional improvement in abdominal muscle strength. Methods: Fifty-seven patients undergoing surgery for ARD completed the VHPQ before surgery. Preoperative pain assessment results were compared with the relative improvement in muscle strength measured with the BioDex system 4. Results: There was a correlation between the relative improvement in muscle strength measured by the BioDex System 4 for flexion at 30 degrees (P = 0.046) and 60 degrees per second (P = 0.004) and the preoperative question, “Do you find it painful to sit for more than 30 minutes?” There was also a correlation between BioDex improvement for flexion at 30 degrees (P = 0.022) and for isometric work load (P = 0.038) and the preoperative question, “Has abdominal pain limited your ability to perform sports activities?” The VHPQ responses also formed a pattern with a fairly good correlation between other BioDex modalities (with the exception of extension at 60 degrees per second) and the response to the question regarding complaints when performing sports. Postoperative visual analog scale ratings of abdominal wall stability correlated to the questions regarding complaints when sitting (P = 0.040) and standing (P = 0.047). No other correlation was seen. Conclusion: VHPQ ratings concerning pain while being seated for more than 30 minutes and pain limiting the ability to perform sports are promising indicators in the identification of patients likely to benefit from surgical correction of their ARD.

    Internal intercostal and abdominal motoneurons are strongly coactivated during expiration. We investigated whether that synergy was paralleled by synergistic Group I reflex excitation. Intracellular recordings were made from motoneurons of the internal intercostal nerve of T8 in anesthetized cats...... or rectus abdominis). Inspiratory Dist motoneurons (assumed to innervate interchondral muscle) showed Dist EPSPs. Stimulation of dorsal ramus nerves gave EPSPs in 12 instances, 9 being in group B Dist motoneurons. The complete absence of heteronymous monosynaptic Group I reflex excitation between......, and the specificity of the monosynaptic connections from afferents in each of the two main branches of this nerve was investigated. Motoneurons were shown by antidromic excitation to innervate three muscle groups: external abdominal oblique [EO; innervated by the lateral branch (Lat)], the region of...

    Abdominal wall endometriosis (AWE) is defined as endometrial tissue that is superficial to the peritoneum. AWE is often difficult to diagnose, mimicking a broad spectrum of diseases. The aim of this study was to describe the appearance of AWE on magnetic resonance (MR) imaging. We present ten patients with AWE (12 lesions) in which MR imaging was used for diagnosis. MR imaging included T2-weighted imaging and T1-weighted imaging with fat suppression. To assess the value of diffusion-weighted imaging (DWI) in endometriosis, four patients underwent additional DWI. The apparent diffusion coefficient (ADC) was calculated using b values of 50, 400, 800 and 1,200 s/mm{sup 2}. In most cases, the lesion was located ventral or dorsal to the aponeurosis of the rectus oblique muscle (n=6) or in the rectus abdominis (n = 5). MR of AWE lesions showed isointense or slightly hyperintense signal compared with muscle on T2-weighted images and showed isointense or slightly hyperintense signal compared with muscle on T1-weighted images with foci of high signal intensity, indicative of haemorrhage. The mean ADC value of AWE was 0.93 x 10{sup -3}/mm{sup 2}/s. MR imaging seems to be useful in determining the location and depth of infiltration in surrounding tissue preoperatively. (orig.)

Moreover, we studied the effect of physical training on epinephrine-stimulated lipolysis in muscle in vivo. Female rats were either swim trained (15 wk, n = 8) or sedentary (n = 7). Under anesthesia, a...... sedentary rats. In skeletal muscle, interstitial glycerol concentration and blood flow did not differ between trained and sedentary rats. In conclusion, in vivo lipolysis is higher both in the basal state and during epinephrine-stimulation in intra-abdominal than in subcutaneous AT, and training may be...

  3. Lipoabdominoplasty: Revisiting the Superior Pull-Down Abdominal Flap and New Approaches

    Uebel, Carlos Oscar

    2009-01-01

    Abdominoplasty is a very common procedure, especially for patients with abdominal laxness, striaes, and muscle rectus diastases. With the advent of liposuction 28 years ago, we can improve body contouring by treating lipodystrophies in the epigastric, flank, trochanteric, and buttocks areas. The procedure combining abdominoplasty and liposuction is called lipoabdominoplasty. Many new techniques have been proposed since these procedures were introduced; we now revisit the superior pull-down ab...

    The menopause is accompanied by increased risk of obesity, altered body fat distribution and decreased skeletal muscle mass. The resulting decrease in RMR should be accompanied by a compensatory change in energy balance to avoid weight gain. We aimed to investigate habitual energy intake and expenditure in pre- and postmenopausal women matched for abdominal obesity. We recruited fifty-one healthy Caucasian women, BMI > 18·5 and

  10. Hypoxia inhibits abdominal expiratory nerve activity.

    Fregosi, R F; Knuth, S L; Ward, D K; Bartlett, D

    1987-07-01

    Our purpose was to examine the influence of steady-state changes in chemical stimuli, as well as discrete peripheral chemoreceptor stimulation, on abdominal expiratory motor activity. In decerebrate, paralyzed, vagotomized, and ventilated cats that had bilateral pneumothoraces, we recorded efferent activity from a phrenic nerve and from an abdominal nerve (cranial iliohypogastric nerve, L1). All cats showed phasic expiratory abdominal nerve discharge at normocapnia [end-tidal PCO2 38 +/- 2 Torr], but small doses (2-6 mg/kg) of pentobarbital sodium markedly depressed this activity. Hyperoxic hypercapnia consistently enhanced abdominal expiratory activity and shortened the burst duration. Isocapnic hypoxia caused inhibition of abdominal nerve discharge in 11 of 13 cats. Carotid sinus nerve denervation (3 cats) exacerbated the hypoxic depression of abdominal nerve activity and depressed phrenic motor output. Stimulation of peripheral chemoreceptors with NaCN increased abdominal nerve discharge in 7 of 10 cats, although 2 cats exhibited marked inhibition. Four cats with intact neuraxis, but anesthetized with ketamine, yielded qualitatively similar results. We conclude that when cats are subjected to steady-state chemical stimuli in isolation (no interference from proprioceptive inputs), hypercapnia potentiates, but hypoxia attenuates, abdominal expiratory nerve activity. Mechanisms to explain the selective inhibition of expiratory motor activity by hypoxia are proposed, and physiological implications are discussed. PMID:3624126

  12. Fetal abdominal magnetic resonance imaging

    This review deals with the in vivo magnetic resonance imaging (MRI) appearance of the human fetal abdomen. Imaging findings are correlated with current knowledge of human fetal anatomy and physiology, which are crucial to understand and interpret fetal abdominal MRI scans. As fetal MRI covers a period of more than 20 weeks, which is characterized not only by organ growth, but also by changes and maturation of organ function, a different MR appearance of the fetal abdomen results. This not only applies to the fetal intestines, but also to the fetal liver, spleen, and adrenal glands. Choosing the appropriate sequences, various aspects of age-related and organ-specific function can be visualized with fetal MRI, as these are mirrored by changes in signal intensities. Knowledge of normal development is essential to delineate normal from pathological findings in the respective developmental stages

  15. The Effect of Postoperative Hyperbaric Oxygen Treatment on Intra-Abdominal Adhesions in Rats

    Yi-Chiang Hsu

    2012-09-01

    Full Text Available Abdominal adhesions, whether caused by peritoneal trauma, radiation, infection, or a congenital condition, are associated with a wide range of complications. These complications include chronic abdominal or pelvic pain, infertility, and adhesive small bowel obstruction. Such adhesions render re-operation difficult, with attendant risks of inadvertent enterostomy and increased operation time. The purpose of this study was to investigate the potential of hyperbaric oxygen (HBO therapy in the prevention of abdominal adhesions in an experimental animal study. A laparotomy was performed on Wistar rats to induce the formation of adhesions on the cecum and the intra-abdominal area (1 ´ 2 cm. A superficial layer of the underlying muscle from the right abdominal wall was also shaved and prepared for aseptic surgery. The rats were divided into four groups according to the duration of HBO therapy; five additional groups were designated according to the conditions of HBO therapy. When the rats were evaluated according to adhesion area and grade, a statistically significant difference was observed between the control and HBO treatment groups (p < 0.005. Results from this study suggest that HBO treatment could reduce adhesion formation; and further suggest that HBO therapy may have therapeutic potential in the treatment of postoperative peritoneal adhesion.

  16. Expiratory muscle control during vomiting - Role of brain stem expiratory neurons

    Miller, A. D.; Tan, L. K.

    1987-01-01

    The neural mechanisms controlling the muscles involved during vomiting were examined using decerebrated cats. In one experiment, the activity of the ventral respiratory group (VRG) expiratory (E) neurons was recorded during induced 'fictive vomiting' (i.e., a series of bursts of coactivation of abdominal and phrenic nerves that would be expected to produce expulsion in unparalyzed animals) and vomiting. In a second, abdominal muscle electromyographic and nerve activity were compared before and after sectioning the axons of descending VRG E neurons as they cross the midline between C1 and the obex (the procedure that is known to abolish expiratory modulation of internal intercostal muscle activity). The results of the study indicate that the abdominal muscles are controlled differently during respiration and vomiting.

  17. Study of Individual Characteristic Abdominal Wall Thickness Based on Magnetic Anchored Surgical Instruments

    Ding-Hui Dong

    2015-01-01

    Full Text Available Background: Magnetic anchored surgical instruments (MASI, relying on magnetic force, can break through the limitations of the single port approach in dexterity. Individual characteristic abdominal wall thickness (ICAWT deeply influences magnetic force that determines the safety of MASI. The purpose of this study was to research the abdominal wall characteristics in MASI applied environment to find ICAWT, and then construct an artful method to predict ICAWT, resulting in better safety and feasibility for MASI. Methods: For MASI, ICAWT is referred to the thickness of thickest point in the applied environment. We determined ICAWT through finding the thickest point in computed tomography scans. We also investigated the traits of abdominal wall thickness to discover the factor that can be used to predict ICAWT. Results: Abdominal wall at C point in the middle third lumbar vertebra plane (L3 is the thickest during chosen points. Fat layer thickness plays a more important role in abdominal wall thickness than muscle layer thickness. "BMI-ICAWT" curve was obtained based on abdominal wall thickness of C point in L3 plane, and the expression was as follow: f(x = P1 × x 2 + P2 × x + P3, where P1 = 0.03916 (0.01776, 0.06056, P2 = 1.098 (0.03197, 2.164, P3 = −18.52 (−31.64, −5.412, R-square: 0.99. Conclusions: Abdominal wall thickness of C point at L3 could be regarded as ICAWT. BMI could be a reliable predictor of ICAWT. In the light of "BMI-ICAWT" curve, we may conveniently predict ICAWT by BMI, resulting a better safety and feasibility for MASI.

  18. The MRI of extraadrenal pheochromocytoma in the abdominal cavity

    The purpose of this study was to summarize the MR appearances of extraadrenal pheochromocytoma in the abdominal cavity and evaluate the capabilities of MRI in diagnosis of the tumor. Eleven consecutive patients with an extraadrenal pheochromocytoma in abdominal cavity who underwent preoperative 0.5 T (n = 5) or 1.5 T (n = 6) superconductor MRI and had a surgical resection were enrolled in the study. The MR scanning protocol included axial T2-weighted imaging with or without fat-suppressed sequences, axial and coronal uncontrast and contrast T1-weighted sequences with or without fat suppression. The extraadrenal pheochromocytomas were found in retroperitoneum (n = 5), the urinary bladder (n = 1), the pelvis (n = 1), the right prerenal area (n = 1), the renal hilus (n = 1), the left paramusculus psoas major (n = 1) and liver (n = 1). The mean maximal diameter of tumors was 55.9 mm (range 17.8-162.2 mm). The high signal intensity was seen on T2-weighted imaging in all tumors compared to muscle or liver, especially with fat suppression. The intratumoral septa and capsules were shown in 63.6% and 72.7% of cases, respectively, which had low signal intensity on T2-weighted imaging. These relative characteristics may be helpful for qualitative diagnosis of extraadrenal pheochromocytomas with MRI. Other usefulness of MRI was to locate the position, to decide the range of tumors and to show well the relationship between the tumor and near structures

    Microgravity and inactivity due to prolonged bed rest have been shown to result in atrophy of spinal extensor muscles such as the multifidus, and either no atrophy or hypertrophy of flexor muscles such as the abdominal group and psoas muscle. These effects are long-lasting after bed rest and the potential effects of rehabilitation are unknown. This two-group intervention study aimed to investigate the effects of two rehabilitation programs on the recovery of lumbo-pelvic musculature following...

  1. The ‘abdominal circulatory pump’: an auxiliary heart during exercise?

    Barbara eUva

    2016-01-01

    Full Text Available Apart from its role as a flow generator for ventilation the diaphragm has a circulatory role. The cyclical abdominal pressure variations from its contractions cause swings in venous return from the splanchnic venous circulation. During exercise the action of the abdominal muscles may enhance this circulatory function of the diaphragm. Eleven healthy subjects (25±7yr, 70±11kg, 1.78±0.1m, 3F performed plantar flexion exercise at ∼4 METs. Changes in body volume (ΔVb and trunk volume (ΔVtr were measured simultaneously by double body plethysmography. Volume of blood shifts between trunk and extremities (Vbs was determined non-invasively as ΔVtr-ΔVb. Three types of breathing were studied: spontaneous (SE, rib cage (RCE, voluntary emphasized inspiratory rib cage breathing and abdominal (ABE, voluntary active abdominal expiration breathing.. During SE and RCE blood was displaced from the extremities into the trunk (on average 0.16± 0.33L and 0.48±0.55L, p<0.05 SE vs RCE, while during ABE it was displaced from the trunk to the extremities (0.22±0.20L p<0.001, p<0.05 RCE and SE vs ABE respectively. At baseline, Vbs swings (maximum to minimum amplitude were bimodal and averaged 0.13±0.08L. During exercise, Vbs swings consistently increased (0.42±0.34L, 0.40±0.26L, 0.46±0.21L, for SE, RCE and ABE respectively, all p<0.01 vs. baseline. It follows that during leg exercise significant bi-directional blood shifting occurs between the trunk and the extremities. The dynamics and partitioning of these blood shifts strongly depend on the relative predominance of the action of the diaphragm, the rib cage and the abdominal muscles. Depending on the partitioning between respiratory muscles for the act of breathing, the distribution of blood between trunk and extremities can vary by up to 1 L. We conclude that during exercise the abdominal muscles and the diaphragm might play a role of an ‘auxiliary heart’.

  3. Abdominal Burkitt lymphoma in children : CT finding

    To evaluate the CT findings of Burkitt's lymphoma involving the abdomen in children We retrospectively analyzed the abdominal CT of ten children who presented with abdominal symptom. They were confirmed by operation in two cases and by fine needle aspiration biopsy in eight to be suffering from Burkitt's lymphoma. We also abdominal ultrasonography(USG)(n=10) and carried out small bowel follow-through examination(SBS)(n=5). Analyses focused on features of the abdominal mass : bowel wall thickening, ascites, lymphadenopathy, and the involvement of intra-abdominal solid organ. Abdominal CT at the time of presentation showed a huge conglomerated mass encasing segments of small bowel and also peripherally displacing bowel loops(n=9), bowel wall thickening(n=10), and ascites(n=10). In three of these cases, we were able to see tumor necrosis and cavity formation. Extensive infiltration into mesenteric fat and obliteration of tissue plane made it impossible to identify on CT the margin of the tumor and the presence of mesenteric lymphadenopathy. In four patients, sonography showed enlarged mesenteric lymph nodes(15-20mm), and in three, retroperitoneal lymph nodes(5mm, 10mm, 12mm in long dimension) were detected on CT and USG. Abdominal CT can reveal the characteristic imaging features of Burkitt's lymphoma in children. These are a huge conglomerate mass with or without cavity formation, that encases the small bowel and infiltrates the mesentery, ascites, and the relatively spared retroperitoneal lymph nodes

  5. Abdominal ultrasonographic findings of Yersiniosis in children

    To review abdominal ultrasonography in Yersinia Pseudotuberculosis(YP) infection. From June 1993 through June 1994, abdominal ultrasonograms were reviewed in 36 patients with YP infection. The age of patients was from 4 to 14 years. A diagnosis of YP infection was made on the basis of isolation of YP from stool (n=15/36, 41.7%) and by documenting at least a minimum agglutination antibody titer of 1;160 or greater (n=34/36, 94.4%). Abdominal US findings were identified in 33/36 (91.7%) of patients with YP infection. US abnormalities included right lower quadrant abdominal lymphadenopathy in 28/36 (77.8%) of cases: increased bilateral renal cortical echogenecity with renal enlargement, 11/36 (30.6%) of cases:hepatosplenomegaly, 6/36 (16.7%) of cases: bowel wall thickening in termnal ileum and cecum, 4/36 (11.1%) of cases:and ascites, 2/36 (5.5%) of cases. Three patients revealed no abdominal sonographic finding. We conclude that abdominal US can help in the diagnosis of YP infection when US demonstrates multiple right lower quadrant abdominal lymphadenopathy, increased renal cortical echogenecity with renal enlargement, hepatosplenomegaly, intestinal wall thickening or ascites

  6. Respiratory muscle pacing with chronically implanted intramuscular Permaloc electrodes: A feasibility study

    James S. Walter, PhD

    2011-02-01

    Full Text Available We tested the feasibility of stimulating upper-intercostal and abdominal muscles plus the diaphragm by using chronically implanted intramuscular electrodes. During two survival surgeries with six dogs, intramuscular electrodes were implanted bilaterally in the three respiratory muscles. Standard stimulation of the diaphragm was conducted. The dorsolateral and ventrolateral abdominal wall areas were stimulated with a 25 mA current. The second to fourth intercostal spaces were stimulated to elicit the largest tidal volume associated with the least coactivation of the serratus and latissimus muscles. Lone diaphragm and upper-intercostal muscle pacing produced inhaled tidal volumes (mean +/- standard error of the mean of 293 +/- 36 mL and 59 +/- 17 mL, respectively. Lone abdominal muscle pacing produced an exhaled volume of 55 +/- 17 mL. Combined pacing of diaphragm and intercostal muscles increased the inhaled volume to 389 +/- 39 mL. The addition of abdominal pacing following the combined stimulation of diaphragm and intercostals increased the exhaled volume to 472 +/- 54 mL. During autopsy, dislodgement of the electrodes overlying the ribs was a concern and probably resulted from loose animal jackets. Chronic intramuscular Permaloc electrodes can be implanted in several respiratory muscles and increase tidal volumes more than diaphragm stimulation alone.

    2010-09-01

    We report a case of combined subcutaneous, intrathoracic, and abdominal splenosis who presented with attacks of flushing, tachycardia and vague abdominal pain. The patient's past medical history included a splenectomy due to abdominal trauma and years later, a lung lobectomy due to recurrent pneumonia. An enhancing solid mass adjacent to the upper pole of the left kidney and nodular pleural based lesions in the left hemi-thorax along with nodular lesions in subcutaneous tissue of the left chest wall suggested possible adrenal malignancy with multiple metastases. Histopathologic examination demonstrated benign lesions of ectopic splenic tissue. PMID:20804314

    A 73-year-old man was transferred for treatment of abdominal aortic aneurysm. He had no history of abdominal surgeries. Grafting between the infra-renal abdominal aorta and the bilateral common iliac arteries was performed. Proximal and distal cross clamps were applied for grafting. He developed chylous ascites on the 5th post-operative day, 2 days after initiation of oral intake. Fortunately, he responded to treatment with total parenteral hyper-alimentation for 10 days, followed by a low-fat diet. There was no recurrence of ascites. PMID:27087873

  10. Roentgenologic evaluation of blunt abdominal trauma

    This study comprises 25 cases of blunt abdominal trauma proved by surgery. It is concluded that visceral damage by blunt abdominal trauma may be suspected, but can not be satisfactorily diagnosed upon a single plane abdominal roentgenologic examination with clinical support. Contrary to some reports in the literature, rupture of the hallow, viscus is more susceptible than solid organ and ileum is more than jejunum. It is a useful roentgenologic sign denoting distension and small cresent air shadow in the duodenal sweep of the damaged pancreas
