Morphology and innervation of brachioradialis and flexor carpi radialis and their utility in tendon transfer surgeries: A Cadaveric Study. Morphologie 2019; 104:91-96. [PMID: 31761660 DOI: 10.1016/j.morpho.2019.10.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Revised: 10/25/2019] [Accepted: 10/29/2019] [Indexed: 10/25/2022]
Abstract
INTRODUCTION The Brachioradialis (BR) muscle flap is easy to harvest, provides a stable coverage to the cubital fossa as it is well vascularized. The BR andflexor carpi radialis (FCR) tendons are utilized in tendon transfer to restore the normal hand function. Therefore, the present study describes the morphology of the muscle bellies and the tendons of BR and FCR along with their pattern of innervation. MATERIALS AND METHODS The study was carried out on 27 upper limbs of formalin-fixed, adult human cadavers. Length and width of the bellies of BR and FCR were measured. The number of motor branches and their distances from the bi-epicondylar line was measured. RESULTS The mean lengths of BR and FCR bellies were 21.22±2.18cm and 16.15±2.39cm, and the lengths of their tendons were, 12.67±1.13cm and 12.48±1.72cm respectively. BR received a single motor branch in 19 upper limbs. However, FCR received single motor branch in 25 limbs as a common trunk. One upper limb received three motor branches to BR, and two upper limbs received two motor branches to FCR. The most proximal and distal branches to the BR were ranged between 6.3-2.2cm proximal to the bi-epicondylar line. Those to the FCR were ranged between 3.5-6.9cm distal to the bi-epicondylar line. CONCLUSION The motor branches to the BR and FCR are variable in their origin, and the knowledge of such variations is essential for identifying them while performing selective neurotomy surgeries.

Abstract
OBJECTIVES In spontaneous pregnancies, endometriosis appears to be a risk factor of miscarriage. The aim of this study is to evaluate the association between endometriosis and miscarriage in spontaneous pregnancy. METHODS We searched the Cochrane Library, Medline of eligible studies from inception to December 2016, without any restriction. We selected studies that compared endometriosis-affected pregnant women to disease-free pregnant women. To ensure the quality of the methodology, the PRISMA criteria have been met at all stages of the development of this meta-analysis. The primary adverse pregnancy outcomes studied was miscarriage. Three reviewers independently extracted the studies' characteristics and outcome data. RESULTS Of 225 identified abstracts, 4 primary studies met our inclusion criteria by comparing spontaneous pregnant patients with endometriosis to disease-free women. Miscarriage rate was higher in the endometriosis group (OR 1.77 [CI 95% 1.13-2.78]). CONCLUSION In spontaneous pregnancies, endometriosis appears to be a risk factor of miscarriages (almost 80% increased risk). Further prospective studies are needed to confirm these results in order to establish the exact impact of endometriosis on spontaneous pregnancy course.

Abstract
Precise anatomical assessment of femoral neck anteversion (FNA) and the neck shaft angles (NSA) would be essential in diagnosing the pathological conditions involving hip joint and its ligaments. The present study was undertaken on 48 fetal femurs to calculate the NSA and FNA in fetuses digitally. End on images of upper end of the femurs were taken for the estimation of FNA and a photograph in a perpendicular plane was taken to calculate the NSA. Microsoft Paint software was used to mark the points and Image J software was used to calculate the angles digitally. The FNA ranged from 17.08º to 33.97 º on right and 17.32 º to 45.08 º on left. The NSA ranged from 139.33 º to 124.91 º on right and 143.98 º to 123.8 º on left. Unpaired t test showed the FNA and NSA of femur did not vary significantly during the third trimester.

Abstract
OBJECTIVE To determine the effect of mode of delivery and perineal injury on sexual function at 6 and 12 months postpartum. DESIGN Prospective cohort study. SETTING Tertiary women's hospital in Melbourne, Australia. POPULATION A cohort of 440 primigravid women. METHODS The Female Sexual Function Index (FSFI) was completed at first visit (7-19 weeks of gestation), and at 6 and 12 months postpartum. MAIN OUTCOME MEASURES A statistically significant difference in total FSFI or domain scores over time according to mode of delivery or perineal injury. RESULTS In this cohort 54% of women had a normal vaginal delivery, 21% had an instrumental delivery, and 25% gave birth by caesarean section. No difference was found in total FSFI or domain scores according to mode of delivery over time between antenatal assessment and 12 months postpartum. Pain was decreased in the caesarean group only at 6 months postpartum. All groups showed pain scores at 12 months that were comparable with antenatal levels. For those who gave birth vaginally, 27% had an intact perineum, 50% had an episiotomy, and 6%, 14%, and 3% had first, second, and third-degree tears, respectively. The only differences between groups were found over time according to perineal injury at 6 months in the arousal domain. At 12 months, total FSFI and domain scores were no different to initial scores. CONCLUSIONS At 12 months postpartum sexual function has returned to early pregnancy levels, irrespective of mode of delivery or perineal injury.

Abstract
Wernicke's encephalopathy (WE) due to causes other than chronic alcohol abuse is an uncommon and often misdiagnosed condition. In the setting of hyperemesis gravidarum, an acute deficiency of thiamine results from body stores being unable to meet increased metabolic demands. The condition produces typical clinical and radiological findings and when diagnosed early and treated promptly has a good prognosis. Magnetic resonance imaging (MRI) is sensitive and specific for diagnosis. We describe three patients with hyperemesis gravidarum who developed WE, and highlight a range of clinical and imaging features important for appropriate diagnosis. A high degree of clinical suspicion is essential. Treatment is often empirical pending results of investigation, and consists of parenteral repletion of thiamine stores. Reversal of MRI findings parallels clinical improvement. Neurologic outcomes are usually good, but half the pregnancies complicated by this condition do not produce healthy children.

Abstract
In this work, an atomic force microscope (AFM) is combined with a confocal Raman spectroscopy setup to follow in situ the evolution of the G-band feature of isolated single-wall carbon nanotubes (SWNTs) under transverse deformation. The SWNTs are pressed by a gold AFM tip against the substrate where they are sitting. From eight deformed SWNTs, five exhibit an overall decrease in the Raman signal intensity, while three exhibit vibrational changes related to the circumferential symmetry breaking. Our results reveal chirality dependent effects, which are averaged out in SWNT bundle measurements, including a previously elusive mode symmetry breaking that is here explored using molecular dynamics calculations.

Abstract
This study aimed to detect perilesional gliosis around solitary cerebral cysticerci (SCC) by magnetisation transfer imaging (MTI), to compare its incidence between patients administered and not administered albendazole. We prospectively randomised patients with SCC and new-onset seizures to treatment with albendazole plus antiepileptics (treatment), or antiepileptics only (control), and performed MRI scans at zero, three, six, 12 and 24 months. Data were analysed for lesion characteristics, perilesional MT hyperintensity and MT ratios, calculated from the lesion and perilesional area. Eighty-one patients' data were analysed (M-41, F-40; ages 6-52 years). About 13% scolices appeared hyperintense on MTI at baseline. T1-isointense cyst walls and perilesional area showed MT hyperintensity in 30 - 41.4%; this proportion increased over time. Persistently visible SCC and stage of degeneration at enrolment did not predict development of MT hyperintensity. MT ratios (range - 98.75 to 49.79) increased over time and differed significantly from normal parenchyma. No difference in MT ratios was noted between treatment and control groups. Qualitative perilesional MT hyperintensity was more often seen in control group. Perilesional gliosis is present in >20% of SCC at six months, and continues to appear on later scans. Gliosis is independent of lesion persistence and stage of degeneration. Pre- and post-contrast MT imaging is equally useful in detection of gliosis. MT ratios from the lesion and perilesional parenchyma are significantly lower than from normal brain tissue at all stages of degeneration, but increase as degeneration occurs and healing progresses. Albendazole therapy does not affect the formation of perilesional gliosis.

Abstract
This paper presents the results of 30 years of water quality monitoring in a tropical water supply reservoir (Vargem das Flores, Brazil). This water body is subjected to eutrophication problems caused by point sources (discharge of untreated sewage) and diffuse pollution (agricultural use in the drainage basin). Emphasis is given here on the estimation of nutrient loads and on the study of the N/P ratio in the water body. In spite of the prevalence of high N/P values, there is a clear trend in the dominance of cyanobacteria in the phytoplankton, which contradicts results from research in temperate aquatic environments. Some restoration measures for Vargem das Flores Reservoir are currently being implemented: construction of wastewater treatment plants, control of recreational activities, erosion control by hydroseeding and use of natural wetlands. Finally some management strategies in order to prevent algae input in the water abstraction system are discussed. Examples of these techniques are the installation of plastic barriers and the construction of an air curtain device.

Abstract
The effects of pre-sowing magnetic treatments on growth and yield of tomato (cv Campbell-28) were investigated under field conditions. Tomato seeds were exposed to full-wave rectified sinusoidal non-uniform magnetic fields (MFs) induced by an electromagnet at 100 mT (rms) for 10 min and at 170 mT (rms) for 3 min. Non-treated seeds were considered as controls. Plants were grown in experimental plots (30.2 m(2)) and were cultivated according to standard agricultural practices. During the vegetative and generative growth stages, samples were collected at regular intervals for growth rate analyses, and the resistance of plants to geminivirus and early blight was evaluated. At physiological maturity, the plants were harvested from each plot and the yield and yield parameters were determined. In the vegetative stage, the treatments led to a significant increase in leaf area, leaf dry weight, and specific leaf area (SLA) per plant. Also, the leaf, stem, and root relative growth rates of plants derived from magnetically treated seeds were greater than those shown by the control plants. In the generative stage, leaf area per plant and relative growth rates of fruits from plants from magnetically exposed seeds were greater than those of the control plant fruits. At fruit maturity stage, all magnetic treatments increased significantly (P < .05) the mean fruit weight, the fruit yield per plant, the fruit yield per area, and the equatorial diameter of fruits in comparison with the controls. At the end of the experiment, total dry matter was significantly higher for plants from magnetically treated seeds than that of the controls. A significant delay in the appearance of first symptoms of geminivirus and early blight and a reduced infection rate of early blight were observed in the plants from exposed seeds to MFs. Pre-sowing magnetic treatments would enhance the growth and yield of tomato crop.

Abstract
AIMS The aim of this study was to examine the circulating levels of vascular endothelial growth factor, following coronary artery bypass graft surgery performed using both standard cardiopulmonary bypass or the 'octopus technique' on the beating heart. BACKGROUND Vascular endothelial growth factor has a number of effects that are beneficial in the setting of coronary artery bypass graft surgery including cardioprotection, potent angiogenic activity and amelioration of intimal hyperplasia. Hypoxia is a powerful stimulator of vascular endothelial growth factor expression yet the ability of ischaemia, occurring during coronary artery bypass graft surgery, to induce vascular endothelial growth factor production is unknown. METHODS AND RESULTS Serum vascular endothelial growth factor levels were determined in patients undergoing coronary artery bypass graft surgery with standard cardiopulmonary bypass (CPB-CABG group; n=20), with off-pump coronary artery bypass; (OP-CABG; n=12) and in patients undergoing non-cardiac major surgery (n=6). The effect of hypoxia on vascular endothelial growth factor release by neonatal rat cardiac myocytes in vitro was studied. In the CPB-CABG group vascular endothelial growth factor levels were significantly increased to 78.5+/-39.3 and 110.5+/-16.3 pg. microl(-1)8 and 24 h post-operatively, declining to 14.9+/-9.9 pg. microl(-1)by 48 h to pre-operative values (14.4+/-8.6 pg. microl(-1)). Significantly higher vascular endothelial growth factor levels were also present in the OP-CABG group 3, 6 and 24 h post-operatively (levels 136. 6+/-29.3, 143+/-26.12 pg. microl(-1)and 93.5+/-20.1 pg. microl(-1), respectively). However, non-cardiac major surgery did not result in elevated vascular endothelial growth factor levels post-operatively (46.36+/-9.76 vs pre-surgery levels of 26.84+/-6.1 pg. microl(-1)). Either 15 min or 3 h of hypoxia stimulated vascular endothelial growth factor release from neonatal rat cardiac myocytes in vitro. Twenty-four and 48 h post hypoxia, levels of vascular endothelial growth factor were significantly elevated by approximately 17.5- and 48.5-fold respectively. CONCLUSIONS These data demonstrate myocardial ischaemia secondary to CPB-CABG and OP-CABG to be a potent stimulator of vascular endothelial growth factor production, which may have implications for graft endothelialization and cardiovascular haemodynamics post-operatively.

Abstract
A high rate of errors of citation and quotation has been reported in the publications of many medical specialties. The aim of this study was to determine the prevalence of citation and quotation errors in otolaryngology/head and neck surgery journals. A retrospective analysis was performed based on the first issue for 1997 of each of four journals: Laryngoscope; Annals of Otology, Rhinology and Laryngology; Clinical Otolaryngyology; and Journal of Laryngology and Otology. A sample of 50 references from each journal was randomly selected and each was checked for accuracy against the original referenced paper. Citation errors were categorized as major, intermediate or minor and quotation errors as major or minor. Citation errors occurred in 37.5% of the references, 11.9% of which were considered major errors. Quotation errors occurred in 17%, with 11.1% major errors. This prevalence is similar to the established error rate in medical literature.

Abstract
OBJECTIVE This study used image processing techniques to quantify the upper eyelid contour of patients with Graves upper eyelid retraction and congenital blepharoptosis. DESIGN The study design was a cross-sectional study. PARTICIPANTS A total of 29 patients with Graves disease, 22 patients with congenital blepharoptosis, and 50 patients with no history of eye disease participated. INTERVENTION The images of the palpebral fissure of all participants were transferred to a personal computer and processed with NIH Image 1.55 software. MAIN OUTCOME MEASURES The following parameters were analyzed: the curvature of the upper eyelid contour, the position of the contour peak relative to the midline, and the ratio between the temporal and nasal upper quadrant areas of the palpebral fissure. RESULTS All upper eyelid contours could be fitted with second-degree polynomial functions. The mean temporal/nasal area ratio was 1.33 mm in patients with Graves disease, 0.92 mm in patients with blepharoptosis, and 1.04 mm in control subjects. The peak of the upper eyelid contour was found to be lateral to the midline in control subjects (1.05 mm) and in patients with Graves disease (2.09 mm). In patients with blepharoptosis, the peak was 0.69 mm medial to the midline. Overall, the distance between the midpupil and the upper eyelid margin was correlated with several factors: the degree of curvature, the position of the peak of the eyelid contour, and the temporal/nasal area ratio. CONCLUSIONS In Graves eyelid retraction, the curvature of the upper eyelid is enhanced, the peak of the contour is displaced laterally, and the temporal upper quadrant area is increased. Conversely, in congenital blepharoptosis, the eyelid is almost flat, the peak of the contour is displaced medially, and the upper quadrant area is diminished. The lateral segment of the upper eyelid is more involved than the nasal segment in both Graves upper eyelid retraction and congenital blepharoptosis.

Abstract
Empyema thoracis remains a common thoracic problem with challenging management strategies. We analysed retrospectively 107 consecutive patients treated for empyema thoracic over a 5-year period. The majority of patients (75%) were male with a mean age of 51 years. Common presenting symptoms were cough, dyspnoea, chest pain and pyrexia. The mean duration of pre-admission symptoms was 7.5 weeks. The causes of empyema were pneumonia, malignancy, iatrogenic injury and trauma. The most frequently isolated organism was Streptococcus milleri. In 71% of patients there was an underlying systemic disorder. Forty-nine patients (46%) underwent an unsuccessful therapeutic procedure prior to admission to the surgical units. In the units, 24 patients received closed intercostal chest tube drainage, 14 of whom required further intervention. Two patients were treated with repeated thoracocentesis. The majority of patients underwent a surgical procedure in the first instance: rib resection and drainage (5), decortication (22), and more extensive procedures (9) with only two patients requiring further surgery. The mean post-operative stay was 16 days and the hospital mortality was 13%. We recommend early referral of all empyema patients to thoracic units, where assessment and definitive procedures can be performed with high chances of success and moderate risk of morbidity and mortality.

Abstract
Antibiotic concentrations in pulmonary tissue samples and plasma were studied in this open investigation. Twenty-nine patients scheduled for elective pulmonary surgery received a single oral dose of 500 mg azithromycin 24, 72, 96 or 120 h prior to the operation; two patients received 250 mg b.i.d. Blood samples were taken before and at the time of resection, and tissue was obtained during surgery. Plasma and tissue concentrations of azithromycin were measured by high performance liquid chromatography (HPLC) and a microbiological bioassay. Only one patient had a detectable plasma concentration of azithromycin (0.13 micrograms/ml), measured 24 h post-dose by HPLC. However, high and sustained levels were found in lung tissue: mean concentrations measured by HPLC were 3.10 micrograms/g (SD +/- 2.17), 2.55 micrograms/g (SD +/- 1.36), 3.94 micrograms/g (SD +/- 2.40) and 3.13 micrograms/g (SD +/- 0.50) at 24, 72, 96 and 120 h, respectively. Bioassay results were similar to those for the HPLC assay. In summary, azithromycin levels in pulmonary tissue remained close to 3 micrograms/g for up to 5 days after a single oral 500 mg dose, in contrast to plasma levels which were much lower. The lung concentrations found are inhibitory for many sensitive respiratory pathogens and short-course azithromycin therapy is therefore a possibility.

The cases of 189 patients treated at the Surgery Service for gastric carcinoma from January 1960 to December 1978 and followed until April 1984 were reviewed in terms of evolutive behavior. Correlations between sex, age, duration of symptoms, site of tumors, lymph node metastases, stage of tumors, operability, resectability, treatment and survival were attempted. With respect to age, of the patients not operated on, survival was longer for more advanced age; the opposite occurred for the group of patients who were operated on. The impairment of lymph nodes was decisive in shortening survival; men were affected more than women and had a worse prognosis. When the tumors were located in the proximal third of the stomach, the survival rate was longer than when they were located in the distal portion and middle third of the stomach. Patients who had experienced digestive symptoms for a long time survived longer than those with a short history. It was concluded that the main prognostic factor was resectability and, regardless of any other variables, only patients from the group submitted to gastric resection survived more than 5 years.
