Full Text Available Through its conversion to dopamine by aromatic l-amino acid decarboxylase (AADC, l-3,4-dihydroxyphenylalanine (l-DOPA replenishes depleted brain dopamine in Parkinson's disease patients. We recently identified GPR143 as a candidate receptor for l-DOPA. In this study, we investigated the behavioral actions of l-DOPA in wild type (wt and Gpr143-deficient mice. l-DOPA dose-dependently (10–100 mg/kg, i.p. induced ptosis under treatment with 3-hydroxybenzylhydrazine, a centrally acting AADC inhibitor. This effect was not mimicked by 3-O-methyldopa. l-DOPA-induced ptosis in Gpr143-deficient mice to a similar extent as in wt mice. These results suggest that l-DOPA induces ptosis in a GPR143-independent fashion in mice.

. As low-salinity, nutrient-rich Arctic Water began to enter Baffin Bay, it contributed to the Baffin and Labrador currents flowing southward. This enhanced freshwater inflow must have influenced the sea ice regime and likely is responsible for poor calcium carbonate preservation that characterizes...... retreat. A transitional unit with high ice-rafted debris content records the opening of Nares Strait at approximately 9,000 cal BP. High productivity in Hall Basin between 9,000 and 6,000 cal BP reflects reduced sea ice cover and duration as well as throughflow of nutrient-rich Pacific Water. The later......Retreat of glacier ice from Nares Strait and other straits in the Canadian Arctic Archipelago after the end of the last Ice Age initiated an important connection between the Arctic and the North Atlantic Oceans, allowing development of modern ocean circulation in Baffin Bay and the Labrador Sea...

2007-01-01

In order to evaluate the role of botulinum toxin induced ptosis as an occlusion method to treat unilateral deep strabismic amblyopia in two uncooperative children, we injected 0.2 ml of diluted botulinum toxin in the levator palpaebrae; low sedation was necessary in one of the two children. In both cases a marked ptosis was achieved, which lasted about four weeks and then gradually resolved completely. The visual acuity of the ablyopic eye increased in both children, making patching easy thereafter. One child developed amblyopia in the injected eye, which was handled successfully using part-time occlusion. No other side effects were noted. Whether this new method could be a simple, safe and effective alternative method of occlusion for the treatment of deep amblyopia in uncooperative children needs to be proven with a larger series of children.

Patients and methods: A prospective comparative randomized single-center study enrolled 110 patients with bilateral congenital ptosis. One group (n=55 underwent AFLS and the second group (n=55 underwent GTS. Exclusion criteria were good levator function, absent Bell’s phenomenon, and abnormal ocular motility. Follow-up period was 2 years. Functional outcome was measured from digital photos by analysis of upper eyelid margin position relative to the superior limbus and classified as very good (<3 mm, good (3–5 mm, poor (>5 mm, and recurrent. Aesthetic outcome was assessed in terms of lid contour, symmetry of eyelid height, and lid crease presence. Complications were also reported. Results: Failure rate (recurrence and complications was less in AFLS (P=0.035. Symmetrical lid height and good contour were more frequently attained by AFLS (P=0.007 and 0.047, respectively. However, the frequency of very good, good, poor, recurrence, lagopthalmos, ectropion, infection, and formed lid crease individually showed no statistically significant difference (P=0.252, 0.482, 1, 0.489, 0.438, 1, 0.618, and 0.506, respectively. Conclusion: AFLS is a better choice in surgery for patients with bilateral congenital ptosis because it has fewer complications and a lesser recurrence rate than GTS.

2016-07-01

Full Text Available Submandibular gland ptosis is a common impediment to obtaining superior surgical aesthetic results in neck lift surgery. Techniques for suspending the submandibular gland have been proposed, but these procedures have the drawbacks of disturbing the floor of the mouth mucosa and periosteum. We present an approach of submandibular gland suspension for the treatment of gland ptosis by employing a platysma and hyoid bone fascia cradle. Our technique was performed on cadaveric models. The platysma muscle and hyoid bone cradle for submandibular gland ptosis was created on the left side of the neck in two cadavers. A submental incision with sharp dissection was performed to raise a supraplatysmal flap. A subplatysmal plane was developed until the submandibular gland was identified. Sutures were used to pexy the platysma to the hyoid bone periosteum and deep cervical fascia, tightening the overlying muscle and in turn elevating the submandibular gland. Submandibular gland ptosis must be corrected in order to achieve exemplary aesthetic results. Our approach of creating a cradle with the platysma and hyoid bone avoids the potential complications of previously described sling procedures, while still maintaining the integrity of the gland and surrounding tissues.

Full Text Available INTRODUCTION: There are various procedures available for ptosis correction. Successful outcome not only depends on correct technique but also choosing appropriate procedure for each patient. Selection of procedure is based on available levator function and also other factors like etiology, severity, Bell’s phenomenon etc. If such varied procedure s are performed in a group of patients based on standard criteria and results are evaluated systematically we can determine what works best for a given patient . AIM : Evaluation of outcome of various surgical procedures for upper eyelid ptosis . METHODOLOGY : 25 eyelids of 20 patients who presented to a tertiary centre in south India with complaint of drooping of upper lid were considered. All subjects underwent complete ocular examination corrected visual acuity and detailed ptosis evaluation with particular emphasis on measurement of levator muscle function, MRD1 (margin reflex distance - 1, palpebral fissure width in different gazes and margin crease distance. The effect of various factors like MRD1, MCD, levator function were assessed, the amount of correction required and appropriate surgical procedure was chosen. Surgical procedure of Levator resection, frontalis sling operation, anterior levator aponeurosis advancement, o r other ptosis correction procedures under appropriate anaesthesia were performed. Post - operative evaluation in terms of visual acuity, MRD, Interpalpebral fissure height, lid symmetry, lagophthalmos and complications (if any was done. RESULTS : Levator muscle resection was done in 28% of eyelids, frontal sling surgery in 60% of eyelids, Levator muscle plication in 8% eyelids and levator muscle disinsertion with frontal sling surgery in 4% eyes. Undercorrection was seen in about 44% of eyelids in varying degrees. 56% of the eyes had optimal correction. Symmetric correction was achieved in 76% of eyelids. CONCLUSION: The influence of various preoperative factors on the

Full Text Available Background: Achieving excellent aesthetic outcomes in reconstruction of large or ptotic breasts is especially challenging. Incorporating a Wise pattern into the mastectomy design is effective in reducing the excess breast skin, however it increases the risk of mastectomy skin necrosis. The aim of this study is to describe surgical maneuvers which optimize aesthetic outcomes, anticipate flap volume requirements, and limit mastectomy skin necrosis in autologous reconstruction in patients with macromastia and grade III ptosis. Methods: This is a retrospective review of operative and clinical records of patients who underwent unilateral or bilateral breast reconstruction with autologous tissue between August 2015 and May 2017. Patients were divided into macromastia and ptosis groups. Key surgical maneuvers for safely achieving aesthetically optimal results were identified. Results: A total of 29 breasts were successfully reconstructed in 19 patients with a Wise pattern mastectomy skin reduction. Free flap weights were similar in both groups, mastectomy weights were greater in the macromastia group, p < 0.05. Complications were limited to three cases of wound breakdown and one case of mastectomy skin necrosis. Total number of revision stages was reduced in unilateral reconstructions when a contralateral breast reduction or mastopexy was performed during the first stage. Conclusions: A Wise pattern can safely and effectively be incorporated into a mastectomy incision design in patients who are not candidates for a nipple sparing mastectomy. Optimal aesthetics are achieved with similar volume flaps for both macromastia and ptosis patients. In cases of unilateral breast reconstruction a contralateral breast reduction or mastopexy should be performed at the time of the immediate breast reconstruction.

A 10-year-old, neutered male Golden Retriever developed repeated stenosis of the nares, at first after bilateral rostral maxillectomy and nasal planum resection, and again after revision surgery. Bilateral, superior labial mucosal transposition flaps were created and interpolated between the nasal mucosa and skin after debridement of scar tissue. The stenosis did not recur after mucosal flap transposition and the dog returned to normal quality of life (last follow-up 25 months postoperative). Single-stage, superior labial mucosal transposition flaps can be used to correct nares stenosis subsequent to previous surgery. © Copyright 2016 by The American College of Veterinary Surgeons.

Full Text Available Objectives: To evaluate the clinical features and the outcome of ptosis surgery in patients with chronic progressive external ophthalmoplegia (CPEO. Materials and Methods: The demographic features, surgical approaches, anatomic and functional outcomes, and complications were reviewed in patients with CPEO who had undergone ptosis surgery by a single surgeon between the years 2005 and 2013. The patients were asked to evaluate their postoperative result as either worse, no change, good, or very good. Results: Seven men and 5 women with an average age of 50±14.08 years (range: 28-72 were included in the study. Ragged red fibers (RRF were identified in 5 out of 9 patients’ levator and orbicularis muscle biopsy specimens. Average levator function was 5.4±2.6 mm (range: 2-9. Frontalis suspension surgery with silicone rod was performed in 8 patients; two of those 8 patients had lower lid elevation with hard palate graft prior to ptosis surgery. The remaining 4 patients had levator resection. Postoperative margin reflex distance -1 was between +1 and +3 in all patients. One patient had punctate keratopathy following surgery, which responded rapidly to intensive use of lubricants. Head position was improved in all patients; postoperative result was rated ‘very good’. Conclusion: Eyelid elevation must be tailored to result in sufficient interpalpebral area so as to allow for normal visual function and avoid exposure keratopathy. Lower eyelid elevation with hard palate graft may help to achieve this goal by displacing the interpalpebral area superiorly without introducing additional risk for corneal exposure.

2015-01-01

Coarse-grained models are useful tools to investigate the structural and thermodynamic properties of biomolecules. They are obtained by merging several atoms into one interaction site. Such simplified models try to capture as much as possible information of the original biomolecular system in all-atom representation but the resulting parameters of these coarse-grained force fields still need further optimization. In this paper, a force field optimization method, which is based on maximum-likelihood fitting of the simulated to the experimental conformational ensembles and least-squares fitting of the simulated to the experimental heat-capacity curves, is applied to optimize the Nucleic Acid united-RESidue 2-point (NARES-2P) model for coarse-grained simulations of nucleic acids recently developed in our laboratory. The optimized NARES-2P force field reproduces the structural and thermodynamic data of small DNA molecules much better than the original force field

Several types of materials have been used, including Gore-Tex®, which has been used successfully as a frontalis sling material since 1986. Recently, a Gore-Tex sheet (wider than a sling or strip suspension was reported. This paper reports the results of 27 eyes from 20 patients with congenital ptosis treated using the frontalis suspension technique with the newly developed Gore-Tex Most Versatile Patch (MVP sheet.Methods: All patients underwent surgery between April 2007 and September 2011 and were followed up for at least one year. The average follow-up duration was 18 months, with a range of 12–36 months. The average patient age was 45 (5–85 years, and the group included 11 males and nine females. Thirteen cases demonstrated ptosis in one eye, and seven cases involved both eyes. The patients were divided by age into a younger group and an older group. All ptosis procedures were performed using the Gore-Tex MVP sheet. The implant was normally 7 mm wide for adults and 5 mm wide for children. The implantation method was the same as that used for the sheet shape fascia.Results: In all patients, satisfactory functional results were observed at the 6-month follow-up examination. Eyelid opening heights were also obtained. The average marginal reflex distance (MRD was -0.5 mm preoperatively, which improved to +1.9 mm after surgery. After one year, average MRD was +1.6 mm. MRD attenuation was more frequent in the younger group. There were no cases requiring redo surgery and only one case of exposure.Keywords: polytetrafluoroethylene, Gore-Tex®, frontalis suspension, congenital ptosis, recurrence

Full Text Available Blepharophimosis ptosis epicanthus inversus syndrome (BPES is a complex eyelid malformation characterized by the classical tetrad of blepharophimosis, telecanthus, ptosis, and epicanthus inversus. It has been reported to be associated with other ocular anomalies such as euryblepharon, strabismus, nystagmus, amblyopia, microphthalmos, lacrimal drainage apparatus abnormality, extra ocular muscle abnormalities, microcornea, trabecular dysgenesis, optic nerve hypoplasias, and colobomas of the optic disk. We describe a case of BPES with Axenfeld-Rieger syndrome, a neurocristopathy characterized by maldevelopment of the anterior segment with predisposition to development of glaucoma. Interestingly, both syndromes are caused by mutations in the same class of genes, namely the winged-helix/forked transcription factors (FOX involved in a variety of developmental processes.

Large sea ice outflow into the Nares Strait in 2007

Kwok, R.; Pedersen, L.T.; Gudmandsen, Preben

2010-01-01

Sea ice flux through the Nares Strait is most active during the fall and early winter, ceases in mid- to late winter after the formation of ice arches along the strait, and re-commences after breakup in summer. In 2007, ice arches failed to form. This resulted in the highest outflow of Arctic sea...... at Fram Strait. Clearly, the ice arches control Arctic sea ice outflow. The duration of unobstructed flow explains more than 84% of the variance in the annual area flux. In our record, seasonal stoppages are always associated with the formation of an arch near the same location in the southern Kane Basin...... ice in the 13-year record between 1997 and 2009. The 2007 area and volume outflows of 87 x 10(3) km(2) and 254 km(3) are more than twice their 13-year means. This contributes to the recent loss of the thick, multiyear Arctic sea ice and represents similar to 10% of our estimates of the mean ice export...

Full Text Available Introduction: To evaluate the cosmetic results and recurrence of unilateral frontalis sling surgery using a silicone rod compared with autogenous fascia lata in cases of simple congenital ptosis. Methods: This is a retrospective comparative study of 59 patients who underwent a frontalis sling operation for congenital ptosis. Patients were divided into two groups according to the sling material used; an autogeneous fascia lata (fl group (n = 24 and a silicone rod group (sl (n = 35. Cosmetic results and recurrence rates were compared between these 2 groups. The cosmetic results of the frontalis sling operation were assessed as good, fair, or poor based on the difference between the Margin Reflex Distance of both eyelids and graded as good if the difference in two eyes was ≤1mm and poor if it was 2mm or more. Recurrence was defined as the conversion of the cosmetic result from good or fair to poor category. Results: At postoperative day seven and 30, MRD of both the groups were good but on three months follow-up MRD of silicon rod group dropped, however it was not statistically significant .Lid contour was good in both the groups, however, lid symmetry was poor in two cases of fascia lata at three months follow-up. Repeat surgery for poor outcome was done in 8.6% of cases in silicon rod and 8.3% of fascia lata group. Conclusions: The frontalis sling operation using either a silicone rod or autogenous fascia lata showed equally good cosmetic results and lower recurrence rate at three months follow up.

We describe our use of a perforated titanium plate to perform a partial posterior fossa cranioplasty in the treatment of cerebellar ptosis and dural ectasia after posterior fossa decompression (PFD). Twelve patients who had undergone PFD underwent posterior fossa reconstruction using a titanium plate. Symptoms were related to either descent of the cerebellum into the decompression or to dural ectasia into the craniectomy defect. Twelve patients who had undergone large suboccipital craniectomies and who presented with persistent headaches and some with neurological symptoms related to syringomyelia, underwent reoperation with placement of a small titanium plate. Ten of 12 patients showed symptomatic improvement after reoperation.

Healthy carriers of Staphylococcus aureus strains have an important role in the dissemination of this bacterium. To investigate the presence of S. aureus in the throat and anterior nares, samples from 1,243 healthy volunteers in a Mexican community were examined. The percentage of healthy carriers was 59.8%. Results showed that colonization of the throat occurred more frequently than that of the nares (46.5% versus 37.1%, P < 0.0001). Of the S. aureus carriers, 22.2% were exclusive nasal carriers and 38% were exclusive throat carriers. A total of 1,039 strains were isolated; 12.6% were shown to be methicillin-resistant S. aureus (MRSA). Of MRSA strains, 32.1% were isolated from exclusive throat carriers. Most of the strains isolated from the anterior nares and throat of the same carriers were the same or related; however, some were different. Pulsed-field gel electrophoresis (PFGE) pattern analysis of the MRSA strains isolated from the exclusive nasal carriers or exclusive throat carriers showed that they belong to different clusters. A 6-year prospective study was performed to investigate the persistence of S. aureus in the throat. Results showed that 13% of subjects were persistent carriers. Most of them were colonized with the same clone of S. aureus throughout the time of the study, and just three had different clones. Antimicrobial susceptibility testing showed that 91.1% of the strains were penicillin resistant. The presence of mecA and nucA genes (in order to confirm methicillin resistance) and of thermostable nuclease of S. aureus was examined. This study showed that some strains of S. aureus regularly colonized the throats of healthy people and could persist for years. PMID:20335416

This document summarizes the status of geoscience investigations in the two primary North Atlantic study locations Great Meteor East (GME) in the Madeira Abyssal Plain, and the Southern Nares Abyssal Plain (SNAP), and assesses the characteristics of these locations relative to the guidelines considered desirable and necessary for a potential subseabed high-level waste repository. These characteristics will be continually reevaluated as additional data become available and as our understanding of deep-sea sediment processes within abyssal plain environments improves. Initially, a number of areas of minimum size were identified in the ocean basins that appeared to comply with most of the stability and barrier guidelines. However, detailed studies in both GME and SNAP demonstrate that as our level of knowledge improves, and the degree of resolution increases, the number of 100 km 2 areas complying with these guidelines becomes much more limited. This observation may be characteristic of abyssal plain and abyssal hill environments in both the North Atlantic and North Pacific basins. Marked differences in geoscience characteristics exist between the Great Meteor East and the Southern Nares Abyssal Plain study locations. The significance of these differences, as they impact the selection of a single preferred site for a potential subseabed repository, can only be determined by using an integrated systems risk assessment modeling approach. The known geoscience characteristics can, however, be used in conjunction with the site assessment guidelines to draw conclusions concerning the geoscience suitability of these two locations. These conclusions will be modified as specific types of data from future expeditions become available

We describe an unusual case of recurrent, refractory anterior epistaxis in an 86-year-old man with two mechanical heart valves who was on permanent warfarin therapy. His numerous episodes of epistaxis were incited by chronic nose-picking and strong nose-blowing, practices that he continued to engage in despite repeated medical advice to stop. Stopping his anticoagulation therapy was not considered as a management option because of an unacceptably high risk that this would lead to a thromboembolic event. Eventually, we temporarily sutured his nares closed, and his nosebleeds ceased. The suturing was performed in the ward with local anesthesia. This procedure was simple to perform,fairly well tolerated, easily reversible, and highly effective.

Full Text Available Congenital ptosis (CP represents a significant reconstructive problem Numerous studies have not yet provided full and satisfactory results. In this study, we have presented our experience in the surgical treatment of 108 patients by the use of Son Ye Guang's modified method - frontal muscle transposition. A total of 108 patients with CP were surgically treated at the Clinic for Plastic Surgery and Burns of the Military Medical Academy in the period 1991-2000. Unilateral ptosis was operated in 85 patients, and bilateral in 23 patients. CP was more frequently found in males (58.34% than in females (41.66%. The youngest patient was only 5.5 years old, and the oldest was 42, the average age was 21.3 years. All patients were operated on by the same surgeon, and were monitored monthly during the first six months and then twice a year for the next 3 years. Postoperative results were evaluated after 6 months: the action of raising the eyelids was compared to the full amplitude of movement of the eye on the healthy side. The closure of the eyelids and the symmetry of the palpebral fissure in a steady horizontal view was also assessed. The action of the opening as well as closure of the eyelids in full amplitude was obtained in all operated patients. Asymmetry of the palpebral fissure in a steady horizontal view up to 1 mm did not require additional correction. In 9 cases, asymmetry of the palpebral fissure greater than 1 mm was subsequently corrected. The advantages of this surgical method compared to the other, previously described techniques, were emphasized in the conclusion. The main advantage was the elimination of postoperative lagophthalmos, which represented the problem in all previously used methods.

Fernando Passos Rocha

Full Text Available CONTEXT: Congenital deformities of the anterior thoracic wall are characterized by unusual development of the costal cartilages. All these medical conditions are frequently associated with a variety of breast deformities. Several surgical techniques have been described for correcting them, going from sternochondroplasty to, nowadays, minimally invasive techniques and silicone prosthesis implantation. CASE REPORT: The present article reports the case of a young female patient who presented bilateral mammary ptosis and moderate pectus excavatum that caused a protrusion between the eighth and the tenth ribs and consequent esthetic disharmony. The proposed surgical treatment included not only subglandular breast implants of polyurethane, but also resection of part of the rib cartilage and a bone segment from the eighth, ninth and tenth ribs by means of a single submammary incision in order to make the scar minimally visible. Correction through a single incision benefited the patient and provided an excellent esthetic result. CONCLUSIONS: The techniques used to repair bilateral mammary ptosis and pectus excavatum by plastic and thoracic surgery teams, respectively, have been shown to be efficient for correcting both deformities. An excellent esthetic and functional result was obtained, with consequent reestablishment of the patient's self-esteem.

Here we report the measurement of low uranium concentrations in composite pore-water samples from the uppermost 20-30 m of deep-sea abyssal plain sediments from the Great Meteor East and Southern Nares Abyssal Plains Area. Many values are the lowest uranium concentrations ever measured in the pore waters of deep-sea sediments. Our lowest value, 0.05 ± 0.01 p.p.b., is orders of magnitude lower than the predicted solubility of U0 2 or U 4 0 9 . The uranium concentrations obtained from both sites correlate closely with measured redox potentials in the sediments. The low mobility of uranium in pore waters from turbiditic deep-sea abyssal plain sediments, which can be deduced from these measurements, has important implications for the sub-seabed disposal of high-level radioactive waste, and for marine geochemistry of uranium.

Romero, Alejandro; Carvajal, Luis

2003-01-01

This work shows three different methodologies for the understanding and forecast of the electric energy prices in the chain Nare - Guatape - San Carlos: lineal multivariate model, autoregressive deterministic model and Fourier series decomposition. The electric energy price depends basically of the reservoir level and river flow, not only its own but the reservoir down and up, waters. About prices forecast, they can be modeled with an autoregressive process. Prices forecast follows the tendency and captures with acceptable precision the maximum prices due especially to the low hydrology and price variability for daily and weekly regulation reservoirs

Oculomotor nerve palsy (ONP) due to internal carotid-posterior communicating artery (PcomA) aneurysm generally manifests as partial nerve palsy including pupillary dysfunction. In contrast, infundibular dilatation (ID) of the PcomA has no pathogenic significance, and mechanical compression of the cranial nerve is extremely rare. We describe a 60-year-old woman who presented with progressive ptosis due to mechanical compression of the oculomotor nerve by an ID of the PcomA. Three-dimensional computer graphics (3DCG) accurately visualized the mechanical compression by the ID, and her ptosis was improved after clipping of the ID. ID of the PcomA may cause ONP by mechanical compression and is treatable surgically. 3DCG are effective for the diagnosis and preoperative simulation.

The geochemistry of a suite of box and 2m gravity cores from the Nares Abyssal Plain has been characterised by means of pore water analyses, XRF determination of major and trace element concentrations, mineralogy and 230 Thsub(excess) dating. The interstitial fluid environment of those deep-sea clays is mildly reducing, although one site exhibits manganese remobilisation and precipitation. Despite their marked colour differences, there is a similarity in clay mineralogy between the grey silt/clay turbidites and the brown clays found in the area. Sediment accumulation rates of pelagic brown clays range between 0.5 and 1.0 cm/10 3 yr. These pelagic brown clays are metal-rich relative to the grey clays, and a model is used to estimate the hydrogenous metal fluxes on the assumption that they are constant over the Plain. This model gives values of approx. 1300 μg/cm 2 /10 3 yr for Mn, approx. 2600 μg/cm 2 /10 3 yr for Fe and Co, Ni, Cu, V and Zn in the range 6 to 26 μg/cm 2 /10 3 yr. An associated model-derived estimate of the detrital contents of the same elements agrees well with the mean values of the grey clays and of average shale. Metal-poor brown clays and assorted minor lithologies are intermediate in composition between these two end-members. (author)

Genomic evolution of Staphylococcus aureus isolates colonizing the nares and progressing to bacteremia.

Full Text Available Nasal colonization by Staphylococcus aureus is a key risk factor for bacteremia. The objective of this study is to identify genomic modifications occurring in nasal carriage strains of S. aureus as they progress to bacteremia in a cohort of hospitalized patients.Eight patients with S. aureus bacteremia were identified. Genomic sequences of the bloodstream isolates were compared with 57 nasal isolates collected longitudinally prior to the occurrence of bacteremia, which covered a timespan of up to 326 days before bacteremia.Within each subject, nasal colonizing strains were closely related to bacteremia strains. Within a subject, the number of single nucleotide polymorphisms (SNPs observed between time points was greater than within a single time point. Co-colonization and strain replacement were observed in one case. In all cases colonization progressed to bacteremia without addition of new virulence genes. In one case, a mutation in the accessory gene regulator gene caused abrogation of agr function.S. aureus evolves in the human nares at a variable rate. Progression of S. aureus nasal colonization to nosocomial infection is seldom associated with acquisition of new virulence determinants. Mutation in the agr gene with abrogation of function was associated with progression to bacteremia in one case.

Blepharophimosis/ptosis/epicanthus inversus syndrome (BPES), an autosomal dominant syndrome in which eyelid malformation is associated with (type I BPES) or without premature ovarian failure (type II BPES). Mutations of a putative winged helix/forkhead transcription factor FOXL2 account for both types of BPES. We report on a 16-year-old adolescent girl with blepharophimosis and ptosis. Subsequently she developed oligomenorrhea, secondary amenorrhea for 6 months, and an extremely large cyst of one ovary. The cyst contained 8 l of cyst fluid and histopathology displayed a large corpus luteum cyst. Following laparotomy, gonadotropin levels were elevated (LH 17.2 U/l, FSH 29.4 U/l) and estradiol levels decreased (67 pmol/l). Because of clinical aspects of BPES and abnormal ovarian function we suspected a mutation of her FOXL2 gene and found a new in-frame mutation (904_939dup36) on one allele, leading to a 12 alanine expansion within the polyalanine domain. We conclude that the FOXL2 mutation 904_939dup36 may account not only for blepharophimosis and ptosis but also for ovarian dysfunction and growth of the large corpus luteum cyst. In contrast to known FOXL2 mutations with polyalanine expansions and association with BPES type II, clinical aspects of our girl may indicate some degree of ovarian dysfunction that might finally lead to BPES type I with premature ovarian failure.

Ryanodine receptor 1 ( RYR1 ) is an intracellular calcium receptor primarily expressed in skeletal muscle with a role in excitation contraction. Both dominant and recessive mutations in the RYR1 gene cause a range of RYR1 -related myopathies and/or susceptibility to malignant hyperthermia (MH). Recently, an atypical manifestation of ptosis, variably presenting with ophthalmoplegia, facial paralysis, and scoliosis but without significant muscle weakness, has been reported in 9 cases from 4 families with bialleic variants in RYR1 . Two affected children from a consanguineous family with severe congenital ptosis, ophthalmoplegia, scoliosis, and distinctive long faces but without skeletal myopathy were studied. To identify the cause of the hereditary condition, DNA from the proband was subjected to whole exome sequencing (WES). WES revealed a novel homozygous missense variant in RYR1 (c.14066T>A; p.IIe4689Asn), which segregated within the family. Although the phenotype of the affected siblings in this study was similar to previously described cases, the clinical features were more severely expressed. Our findings contribute to the expansion of phenotypes related to RYR1 dysfunction. Additionally, it supports a new RYR1 -related clinical presentation without musculoskeletal involvement. It is important that individuals with RYR1 mutations are considered susceptible to MH, as 70% of the MH cases are caused by mutations in the RYR1 gene.

The ossicles represent one of the most fundamental morphological features in evolutionary biology of the mammalians. The mobile ossicular morphology abnormalities result in the severe conductive hearing loss. Development and patterning of the middle ear malformation depend on genetic and environmental causes. However, the genetic basis for the risk of congenital ossicle malformation is poorly understood. We show here nine affected individuals in a Chinese pedigree who had bilateral conductive hearing loss with ptosis. We performed whole-genome sequencing and array comparative genomic hybridization (CGH) analysis on DNA samples from the Chinese pedigree. We confirmed the presence of a novel 60 kb heterozygous deletion in size, encompassing SIX2 in our family. Mutation screening in 169 sporadic cases with external ear and middle ear malformations identified no pathogenic variant or polymorphism. We suggest SIX2 haploinsufficiency as a potential congenital factor could be attributed to developmental malformation of the middle ear ossicles and upper eyelid. To the best of our knowledge, this is the first report to provide a description of copy number variation in the SIX2 gene resulting in syndromic conductive hearing loss.

Staphylococcus aureus is highly prevalent among patients with atopic dermatitis (AD), and this pathogen may trigger and aggravate AD lesions. The aim of this study was to determine the prevalence of S. aureus in the nares of pediatric subjects and verify the phenotypic and molecular characteristics of the isolates in pediatric patients with AD. Isolates were tested for antimicrobial susceptibility, SCCmectyping, and Panton-Valentine Leukocidin (PVL) genes. Lineages were determined by pulsed-field gel electrophoresis and multilocus sequence typing (MLST). AD severity was assessed with the Scoring Atopic Dermatitis (SCORAD) index. Among 106 patients, 90 (85%) presented S. aureus isolates in their nares, and 8 also presented the pathogen in their skin infections. Two patients had two positive lesions, making a total of 10 S. aureusisolates from skin infections. Methicillin-resistant S. aureus(MRSA) was detected in 24 (26.6%) patients, and PVL genes were identified in 21 (23.3%), including 6 (75%) of the 8 patients with skin lesions but mainly in patients with severe and moderate SCORAD values (P=0.0095). All 24 MRSA isolates were susceptible to trimethoprim/sulfamethoxazole, while 8 isolates had a minimum inhibitory concentration (MIC) to mupirocin >1024 μg/mL. High lineage diversity was found among the isolates including USA1100/ST30, USA400/ST1, USA800/ST5, ST83, ST188, ST718, ST1635, and ST2791. There was a high prevalence of MRSA and PVL genes among the isolates recovered in this study. PVL genes were found mostly among patients with severe and moderate SCORAD values. These findings can help clinicians improve the therapies and strategies for the management of pediatric patients with AD.

Background: Recovery of Bell`s phenomenon after levator resection is unpredicatable. Delayed recovery can result in vision threatening corneal complications. Aim: To study the variability of Bell’s phenomenon and time taken for its recovery following levator resection for blepharoptosis and to correlate it with the amount of resection. Methods: A prospective observational study was conducted on 32 eyes of 32 patients diagnosed as unilateral simple congenital blepharoptosis who underwent levator resection at a tertiary care center between July 2013 and May 2015. Patients were followed up for 5 months and correction of ptosis, type of Bell`s, duration of Bell`s recovery and complications were noted. Results: The study group ranged from 16-25 years with 15:17 male: female ratio. There were 9 mild, 16 moderate and 7 severe ptosis. Satisfactory correction was achieved in all cases. Good Bell`s recovery occurred in 13 eyes on first post-op day, in 2-14 days in 19 eyes and 28 days in 1 eye. Inverse Bell`s was noted along with lid oedema and ecchymosis in 2 patients. Large resections (23-26mm) were associated with poor Bell`s on the first postoperative day (p=0.027, Fisher`s exact test). However, the duration required for recovery of Bell`s phenomenon did not show any significant difference with the amount of resection. (p=0.248, Mann Whitney test). Larger resections resulted in greater lagophthalmos (correlation=0.830, p<0.0001). Patients with recovery of Bell`s delayed for more than 7 days were associated with greater number of complications (p=0.001 Fisher`s Exact Test). Conclusion: Close monitoring for Bell`s recovery is required following levator resection. PMID:28584563

Full Text Available Context: Community associated methicillin resistant Staphylococcus aureus (CA-MRSA cause serious skin and soft tissue infections including necrotizing fasciitis and necrotizing pneumonia. Production of Panton Valentine Leucocidine (PVL toxin is implicated in its enhanced virulence. A variant of epidemic MRSA-15 (EMRSA-15 which produces PVL toxin has been isolated and characterized by pulsed-field gel electrophoresis (PFGE method from the Indian population both in hospital and community settings. Aims: Identify the epidemiological type of MRSA colonizing the anterior nares of school children in Udupi taluk. Settings and Design: The study population included children of the age group of 5-16 years belonging to the Udupi taluk of Karnataka, India. A total of 1503 children were screened for MRSA colonization during July 2009 to December 2010. Materials and Methods: PVL assay, Staphylococcal Cassette Chromosome (SCC mec typing and PFGE typing were carried out with all the MRSA isolates. Statistical Analysis Used: Frequency distribution of different variables was assessed by SPSS. Results: Among the 1.1% of MRSA, 58.8% (10/17 of isolates were positive for pvl and 41.7% (7/17 were identified as SCC mec type IV. PFGE patterns of all the strains were identical with Indian variant EMRSA-15; however they were different from classical EMRSA-15 in 3-4 bands. Conclusions: The Indian variant EMRSA-15 gains much epidemiological relevance owing to the acquisition of pvl gene. In spite of low prevalence of nasal colonization of MRSA, emergence of the virulent Indian variant EMRSA-15 in our community is a worrisome fact to be reckoned with.

Full Text Available We describe a 4-year-old female child with a dysmorphic and neurological syndrome of trigonocephaly, mental and psychomotor retardation and dysmorphic facial features. The anomalies of the face were the following: slight upward palpebral fissures, ocular hypertelorism, depressed nasal bridge, hypoplastic nasal root, short nose with anteverted nares; small low set ears, smooth broad philtrum and thin upper lip. The patient had important cerebral anomalies with diffuse alterations in white matter that caused developmental delay with verbal and nonverbal disabilities and severe learning difficulties. This clinical presentation is compatible with the diagnosis of the Opitz C syndrome, a heterogeneous disease of multiple neurological and craniofacial abnormalities. The physical sign more detectable and notorious is the trigonocephaly that is manifested by a prominent metopic suture, but also can be distinguished the other minor facial anomalies that are found in the eyes, nose, mouth and ears that constitute the phenotype of the disorder. The neurological development was altered by the compression of the cerebral frontal lobes with narrowing of this cerebral area, producing hypotonia with muscle weakness, epileptic episodes manifested by seizures, and neurobehavioral and neurocognitive disorders. This syndrome is a very rare genetic disorder with autosomal recessive inheritance trait; our patient had no chromosomal abnormality in the usual karyotype but the fluorescence in situ hybridization (FISH technique showed a balanced translocation between the chromosomes two and eleven: t(2:11 (q32.2/q24.

, hypogonadism and feeding difficulties. Female carriers are often phenotypically normal or show a similar but milder phenotype, as in most cases the X-chromosome harbouring the duplication is subject to inactivation. Xq28, which includes MECP2 is the major locus for submicroscopic X-chromosome duplications......, whereas duplications in Xq25 and Xq26 have been reported in only a few cases. Using genome-wide array platforms we identified overlapping interstitial Xq25q26 duplications ranging from 0.2 to 4.76 Mb in eight unrelated families with in total five affected males and seven affected females. All affected...... males shared a common phenotype with intrauterine- and postnatal growth retardation and feeding difficulties in childhood. Three had microcephaly and two out of five suffered from epilepsy. In addition, three males had a distinct facial appearance with congenital bilateral ptosis and large protruding...

Gynecomastia is a morphostructural impairment of the mammary region in men caused by parenchymal hypertrophy or a cutaneous distortion of breast skin covering or both. The clinical classification introduced by Simon et al. in 1973 ranks gynecomastia in three degrees. Each subtype can be treated with a specific technique. This article describes an alternative surgical procedure for treating gynecomastia with severe ptosis(type III and type IIIb of Simon's classification). Fifty-eight patients were treated for gynecomastia in our Plastic Surgery Unit from 1996 to 2004. The cutaneous excess of periareolar skin is evaluated by a pinching test. A circular periareolar mark is traced corresponding to the cutaneous excess that has to be removed.Initially, liposuction of adipous tissue on the periphery of the mammary region is performed through two cutaneous 3-mm incisions at the 3 o'clock and 9 o'clock positions around the areola. After this, the liposuction incisions are enlarged from 10 o'clock to 8 o'clock and from 2 o'clockto 4 o'clock to create access for the mastectomy. This dissection creates a double dermal areolar pedicle. The new areolar position is fixed with a Benelli round block suture. A resolution of the morphologic deformity without evident scars after hair growth and a correction of the breast deformity has been observed in the 6-month follow-ups conducted for all the patients. We observed that the vascular-nervous net under the areola at 12 o'clock and 6 o'clock is very important, more so than the lateral pedicle, and the conservation of a double vascular-nervous pedicle reduces significantly the risk of areolar necrosis, especially in cases of gynecomastia type III and in cases where there is a high degree of breast malformation such as the tuberous breast.

Outcome of periacetabular osteotomy for the management of acetabular dysplasia: experience in an academic centre.

LENUS (Irish Health Repository)

Burke, Neil G

2011-02-01

Periacetabular osteotomy (PAO) is a very effective reconstructive procedure for treatment of acetabular dysplasia. An orthopaedic paediatric surgeon and a reconstructive hip arthroplasty surgeon performed this procedure together in the early phase of their learning curve and then performed it individually. The early clinical and radiographic results of 85 consecutive PAOs performed in this academic orthopaedic unit were reviewed. The mean Merle-d\\'Aubigné score increased from 12.4 preoperatively to 16 at follow-up. Pre-operatively 73 hips were anteverted and 12 were neutral or retroverted. The mean angle of Wiberg improved from 5 degrees to 21 degrees (p < 0.0001) in anteverted hips, and from 9 degrees to 30 degrees in neutral or retroverted hips. The mean angle of Lequesne and de Sèze improved from 6 degrees to 35 degrees (p < 0.0001) in anteverted hips, and in neutral or retroverted hips from 9 degrees to 30 degrees (p < 0.0001). The acetabular index improved from 26 degrees to 8 degrees (p < 0.0001) in anteverted hips, and from 21 degrees to 7 degrees (p < 0.0001) in neutral or retroverted hips. Over the 7 year period the blood loss and operative time improved from 2000 ml to 900 ml and 4 hours to 2 hours respectively. Four hips (four patients) required conversion to total hip replacement. The radiographic correction and improved clinical scores are similar to those in previous studies. This study shows a survival rate of 94% at 58 months following periacetabular osteotomy. The learning curve and the early results of this procedure performed in our academic unit are encouraging.

The fork-head transcription factor gene (FOXL2) gene has been implicated in Blepharophimosis Ptosis Epicanthus Inversus Syndrome (BPES) type I and type II. The authors aimed to evaluate the involvement of FOXL2 in familial and sporadic cases of BPES in an Indian cohort. The present cohort comprised clinically well-characterised BPES cases that included six affected families, two sporadic cases and 60 unaffected normal controls. The 5' untranslated and coding region of FOXL2 was screened by resequencing and confirmed by restriction digestion. Further, genotype-phenotype correlations were done to understand the implications of the observed mutation. Six mutations were observed in eight cases (87.5%). These included a novel deletion (c.860delC), three previously reported duplications (c.663-692dup 30, c.672-701dup30 and c.843-859dup17), a frame shift (c.804dupC) and a homozygous missense mutation (p.E69K). The p.E69k mutation was seen in both heterozygous and homozygous form in a large four-generational family, and disease severity was found to be directly linked to the allelic dosage. Two SNPs (c.501C→T, c.536C→G) were also noted. An unusual coexistence of polycystic ovarian disease (PCOD) with BPES was also seen in one of the families. Mutations in the region downstream of the fork-head domain were predominantly responsible for BPES among Indian patients.

Pubic contouring after massive weight loss in men and women: correction of hidden penis, mons ptosis, and labia majora enlargement.

Science.gov (United States)

Alter, Gary J

2012-10-01

Weight gain and subsequent weight loss usually result in unsightly large fat deposition in the pubic areas along with ptosis of the fat pad and skin. Men also complain of burying of the penis and the woman complains of labia majora enlargement, both causing secondary sexual dysfunction, hygiene issues, discomfort, and aesthetic concerns. Even with weight loss, most of these deformities persist. The hidden (buried) penis is characterized by a lack of firm attachments between the Buck fascia surrounding the tunica albuginea of the corpora and the dartos fascia and skin. Successful treatment requires the penile skin and dartos fascia to be stabilized to the penile corporal bodies to make the penis one integrated unit. The method of surgery is usually to excise and lift excess pubic skin, eliminate the pubic fat without creating a significant pubic concavity, and stabilize the penile skin to the corporal bodies with tacking sutures dorsally and ventrally. If inadequate penile skin is present, scrotal flaps or skin grafts are used to cover the penis. Treatment of the mons pubis requires similar pubic lifting, fat excision, and pubic tacking. Labia majora reduction requires skin and usually fat excision. Results are excellent with the use of these techniques. Pubic contouring after massive weight loss in men and women is very successful and safe if performed meticulously. Treatment improves self-esteem along with the associated physical and aesthetic deformities.

Petermann Glacier at 81 N latitude is a major outlet glacier adjacent to Nares Strait. It terminates in a long (70 km), narrow (16 km) and thin (50 m) floating tongue and has a grounding line more than 500 m below sea level. A calving event in 2010 reduced the floating area by 25% and produced a single 240 km2 ice island currently moving south in Nares Strait where it will likely interact with island to potentially create a temporary polynya in Nares Strait. The 2010 calving from Petermann Glacier contributes bridge formed regularly at the southern end of Nares Strait creating the North-Water polynya near 79 N latitude. Since 2006 this ice bridge has largely failed to form, leading, perhaps, to the occasional formation of a secondary ice bridge 300 km to the north where Nares Strait connects to the Arctic Ocean. However, this ice bridge appears to form for shorter periods only. Consequently Arctic sea ice can now exit the Arctic in winter via pathways to the west of Greenland all year. We speculate that this changed ocean and sea ice regime in Nares Strait and the Arctic Ocean may contribute to the recently observed calving events in Petermann Fjord.

Third cranial nerve palsy (ptosis, diplopia accompanied by orbital swelling: case report of unusual clinical presentation of giant cell arteritis associated with polymyalgia rheumatica

Full Text Available IntroductionGiant cell arteritis (GCA is the most common systemic vasculitis in older individuals, characterized by granulomatosus inflammation of the wall of large and medium-sized arteries. The wide spectrum of arterial sites involved leads to ischemia of different organs resulting in a wide range of clinical signs and symptoms. Temporal artery is commonly involved (temporal arteritis. Unusual patterns of presentation, such as extraocular motility disorders and orbital swelling, may be early and transient manifestations of GCA and precede the permanent visual loss due to ischemic optic neuropathy.Case reportWe describe a patient with uncommon manifestations of GCA consisting of transient recurrent diplopia, ptosis, orbital swelling together with more typical clinical features of the disease such as musculoskeletal manifestations (polymyalgia rheumatica and facial pain: all signs and symptoms promptly resolved under corticosteroid therapy without relapse.Conclusions A high level of suspicion of GCA in individuals over the age of 50 years is needed to prevent the development of severe complications. Clinicians should be aware of uncommon manifestations of the disease such as head–neck swelling and ophthalmoplegia: management guidelines have stated that prompt administration of adequate dose of corticosteroids as soon as ocular manifestations of GCA are noted may almost totally prevent blindness.

KIAA2022 is an X-linked intellectual disability (XLID) syndrome affecting males more severely than females. Few males with KIAA2022 variants and XLID have been reported. We present a clinical report of two unrelated males, with two nonsense KIAA2022 pathogenic variants, with profound intellectual disabilities, limited language development, strikingly similar autistic behavior, delay in motor milestones, and postnatal growth restriction. Patient 1, 19-years-old, has long ears, deeply set eyes with keratoconus, strabismus, a narrow forehead, anteverted nares, café-au-lait spots, macroglossia, thick vermilion of the upper and lower lips, and prognathism. He has gastroesophageal reflux, constipation with delayed rectosigmoid colonic transit time, difficulty regulating temperature, several musculoskeletal issues, and a history of one grand mal seizure. Patient 2, 10-years-old, has mild dysmorphic features, therapy resistant vomiting with diminished motility of the stomach, mild constipation, cortical visual impairment with intermittent strabismus, axial hypotonia, difficulty regulating temperature, and cutaneous mastocytosis. Genetic testing identified KIAA2022 variant c.652C > T(p.Arg218*) in Patient 1, and a novel nonsense de novo variant c.2707G > T(p.Glu903*) in Patient 2. We also summarized features of all reported males with KIAA2022 variants to date. This report not only adds knowledge of a novel pathogenic variant to the KIAA2022 variant database, but also likely extends the spectrum by describing novel dysmorphic features and medical conditions including macroglossia, café-au-lait spots, keratoconus, severe cutaneous mastocytosis, and motility problems of the GI tract, which may help physicians involved in the care of patients with this syndrome. Lastly, we describe the power of social media in bringing families with rare medical conditions together. © 2018 Wiley Periodicals, Inc.

Simpson-Golabi Behmel syndrome (SGBS) is an X-linked disorder characterized by pre- and postnatal macrosomia, minor facial anomalies, and variable visceral, skeletal, and neurological abnormalities. Since its first description by Simpson et al., a wide clinical range of cases has been reported. There is great variability in severity, ranging from a mild form associated with long-term survival to an early lethal form with multiple congenital anomalies and severe mental retardation. In 8 reported families, affected individuals died in infancy. Here we present 4 maternally related, male cousins with a severe variant of SGBS. One of these males was aborted therapeutically at 19 weeks of gestation following the detection of multicystic kidneys on ultrasound. The 3 liveborn males were hydropic at birth with a combination of craniofacial anomalies including macrocephaly; apparently low-set, posteriorly angulated ears; hypertelorism; short, broad nose with anteverted nares; large mouth with thin upper vermilion border; prominent philtrum; high-arched or cleft palate; short neck; redundant skin; hypoplastic nails; skeletal defects involving upper and lower limbs; gastrointestinal and genitourinary anomalies. All 3 patients were hypotonic and neurologically impaired from birth. With the exception of a trilobate left lung in one patient, the cardiorespiratory system was structurally normal. All patients died within the first 8 weeks of life of multiple complications including pneumonia and sepsis. Two SGBS kindreds, with moderate expression of the condition, have been mapped to Xq27. It is not known whether severe, familiar cases, such as ours, are genetically distinct from and map to another locus. Final resolution of the genetic basis of the phenotypic variability in SGBS must await cloning and mutation analysis of the SGBS gene(s). 21 refs., 4 figs., 1 tab.

Skin-sparing mastectomy and prosthetic reconstruction can be complicated by poor surgical outcomes in large-breasted, obese women. This article describes a single surgeon's experience comparing conventional skin-sparing mastectomy (SSM) and skin-reduction mastectomy using an autologous vascularized inferior dermal/cutaneous sling (autoderm). From July 2007 to May 2012, patients undergoing skin-sparing mastectomy were evaluated for surgical outcomes. After July 2009, the surgeon performed skin-reduction mastectomies with autoderm (SRM-AD) on all patients with macromastia or grade 3-4 ptosis. Remaining patients in this time period (SSM-cont) underwent conventional skin-sparing mastectomies while all previous patients (historical) also underwent skin-sparing mastectomies (SSM-hist). A predictive model was used to compare the large historical patients (who would have had reduction mastectomy if available) with the smaller historical patients to evaluate the effect of the procedure. Body mass index (BMI) and specimen weight were higher in both the SRM group and large historical group. The hazard ratio for having skin-reduction mastectomy was 0.53 (P = 0.51) compared with the historical group. There was a total of 16 complications for the whole study. Smoking was the only significant risk factor. This study shows that mastectomy with prosthetic reconstruction using a skin-reduction technique with autoderm can be done safely with a low complication rate and improved cosmetic outcomes in the traditionally "at-risk" group of women with high BMI and large ptotic breasts.

Common side effects during hyaluronic acid filler injections are typically mild and reversible, but several reports of blindness have received attention. The present study focused on orbital symptoms combined with blindness, aiming to classify affected patients and predict their disease course and prognosis. From September of 2012 to August of 2015, nine patients with vision loss after filler injection were retrospectively reviewed. Ptosis, ophthalmoplegia, and enophthalmos were recorded over a 6-month follow-up, and patients were classified into four types according to periocular symptom manifestation. Two patients were categorized as type I (blindness without ptosis or ophthalmoplegia), two patients as type II (blindness and ptosis without ophthalmoplegia), two patients as type III (blindness and ophthalmoplegia without ptosis), and three patients as type IV (blindness with ptosis and ophthalmoplegia). The present study includes previously unpublished information about orbital symptom manifestations and prognosis combined with blindness caused by retinal artery occlusion after cosmetic filler injection.

Holoprosencephaly (HPE), the most common malformation of the brain, results from failed or incomplete separation of the embryonic forebrain (prosencephalon). HPE occurs in approximately 1 in 250 embryos and in about 1 in 10,000 births. It is etiologically heterogeneous, and may be caused by cytogenetic anomalies and teratogenic influences; it occurs as part of a syndrome, or due to heterozygous mutations in 1 of over 10 HPE-associated genes. ZIC2 mutations are the second-most common cause of non-syndromic non-chromosomal HPE (after sonic hedgehog) and occur de novo in 74% of the affected probands. The objective of the study was to describe the first case of ZIC2-related HPE with both anterior and posterior pituitary insufficiencies. We report about a 2-year-8-month-old boy who was born as a second child in a non-consanguineous healthy Turkish family. He has the characteristic ZIC2 phenotype: bitemporal narrowing, upslanting palpebral fissures, large ears, short nose with anteverted nares and broad and deep philtrum. Magnetic resonance imaging revealed alobar HPE. During laboratory investigation, his blood sodium level was 158 mmol/L and the specific gravity of his urine was 1.002. Serum osmolarity was 336 mOsm/L and urine osmolality was 135 mOsm/kg. His FT4 was 0.8 ng/dL and TSH was 0.79 mLU/mL. Response to vasopressin confirmed the diagnosis of central diabetes insipidus and TRH-stimulating test supported the central hypothyroidism. A frameshift mutation (NM_007129.2:c1091_1092 del, p.Gln364Leufs*2) in the ZIC2 gene was detected. Pituitary insufficiency other than isolated diabetes insipidus is a rare finding of HPE, and occurs most frequently in patients with GLI2 mutations (the phenotype of which typically does not include frank neuroanatomic anomalies such as HPE); ours is the only described patient with a ZIC2 mutation and both anterior and posterior pituitary dysfunction.

Full Text Available Aim: To observe the incidence of full or partial eyelid closure at death. Materials and Methods: The presence of ptosis was recorded in 100 consecutive hospice patient deaths. Results: Majority (63% of the patients died with their eyes fully closed, however, 37% had bilateral ptosis at death, with incomplete eye closure. In this study, central nervous system tumor involvement and/or acute hepatic encephalopathy appeared to be pre-mortem risk factors of bilateral ptosis at death. Conclusion: Organicity and not psychogenicity is, therefore, the likely etiology of failure of full eyelid closure at death.

Full Text Available Aim. To estimate the clinical significance of anti-acetylcholine receptor antibody (anti-AChR-Ab levels in suspected ocular myasthenia gravis. Methods. In total, 144 patients complaining of fluctuating diplopia and ptosis were evaluated for serum levels of anti-acetylcholine receptor antibody and their medical charts were retrospectively reviewed. Subjects were classified into three groups: variable diplopia only, ptosis only, and both variable diplopia and ptosis. We investigated serum anti-AChR-Ab titer levels and performed thyroid autoantibody tests. Results. Patients’ chief complaints were diplopia (N=103, ptosis (N=12, and their concurrence (N=29. Abnormal anti-AChR-Ab was observed in 21 of 144 patients (14.1%. Between the three groups, mean age, number of seropositive patients, and mean anti-AChR-Ab level were not significantly different (P=0.224, 0.073, and 0.062, resp.. Overall, 27.5% of patients had abnormal thyroid autoantibodies. Conclusion. The sensitivity of anti-AChR-Ab was 14.1% in suspected ocular myasthenia gravis and seropositivity in myasthenia gravis patients showed a high correlation with the presence of thyroid autoantibodies.

Full Text Available Presentamos una nueva técnica de mastopexia, más sencilla, que evita recidivas además de disminuir el riesgo de carcinoma mamario. El estudio se realiza sobre 25 pacientes femeninas de 25 a 50 años de edad, con ptosis mamaria. Con las pacientes de pie realizó el marcaje tradicional; si las mamas son pequeñas se colocan implantes en el plano submuscular, y si son grandes, en retroglandular. Para evitar recidivas se colocaron dos tirantes internos con suturas irreabsorbibles. Si el complejo resultante glándula-implante es grande y pesado, se fija un tirante de mama al periostio hemiclavicular y otro al periostio de la tercera costilla; si es pequeño o mediano, únicamente se fija a la costilla. Realizamos controles entre 1 mes y 3 años tras la intervención. Conseguimos corregir ptosis de entre 5 a 12cm., sin recidiva en ninguno de los controles, ni pseudo-ptosis postoperatoria. El ejercicio físico fue posible a los 15 días de la cirugía con el apoyo de un sujetador elástico. La cicatrización fue altamente satisfactoria. Las únicas complicaciones presentadas fueron dehiscencias parciales en 2 pacientes y sensación de ardor, tirantez y elongación de la areola en pacientes cuya ptosis excedía los 12cm y con areolas grandes. La facilidad de ejecución de la técnica y su seguridad, permiten que la cirugía sea ambulatoria. Proponemos esta técnica, que denominamos de quinta generación, que evita la cicatriz periareolar, la inframamaria, la vertical y la "T" invertida; además, elimina parte de ambos cuadrantes superiores de la mama, lo que disminuye notablemente la posibilidad de desarrollar ulteriores casos de carcinoma mamario y evita recidivas con el uso del tirante clavicular.We present a new mastopexy technique, simpler, which precludes the recidivism and reduces the risk of breast cancer.

Full Text Available Sixteen years after scleral buckle surgery with a hydrogel episcleral exoplant, a 43-year-old woman presented with progressive binocular diplopia, ptosis, and an expanding mass in her upper eyelid. She underwent surgical removal of the hydrogel exoplant through an anterior approach. The exoplant proved to be friable, fragmented, and encapsulated in a fibrous tissue; the exoplant was removed in its entirety. Postoperatively, the eyelid mass resolved, while her diplopia and ptosis improved slightly.

Staphylococcus aureus [methicillin-resistant and methicillin-susceptible (MRSA/MSSA)] is a leading cause of infections in military personnel, but there are limited data regarding baseline colonization of individuals while deployed. We conducted a pilot study to screen non-deployed and deployed healthy military service members for MRSA/MSSA colonization at various anatomic sites and assessed isolates for molecular differences. Colonization point-prevalence of 101 military personnel in the US and 100 in Afghanistan was determined by swabbing 7 anatomic sites. US-based individuals had received no antibiotics within 30 days, and Afghanistan-deployed personnel were taking doxycycline for malaria prophylaxis. Isolates underwent identification and testing for antimicrobial resistance, virulence factors, and pulsed-field type (PFT). 4 individuals in the US (4 isolates- 3 oropharynx, 1 perirectal) and 4 in Afghanistan (6 isolates- 2 oropharynx, 2 nare, 1 hand, 1 foot) were colonized with MRSA. Among US-based personnel, 3 had USA300 (1 PVL+) and 1 USA700. Among Afghanistan-based personnel, 1 had USA300 (PVL+), 1 USA800 and 2 USA1000. MSSA was present in 40 (71 isolates-25 oropharynx, 15 nare) of the US-based and 32 (65 isolates- 16 oropharynx, 24 nare) of the Afghanistan-based individuals. 56 (79%) US and 41(63%) Afghanistan-based individuals had MSSA isolates recovered from extra-nare sites. The most common MSSA PFTs were USA200 (9 isolates) in the US and USA800 (7 isolates) in Afghanistan. MRSA/MSSA isolates were susceptible to doxycycline in all but 3 personnel (1 US, 2 Afghanistan; all were MSSA isolates that carried tetM). MRSA and MSSA colonization of military personnel was not associated with deployment status or doxycycline exposure. Higher S. aureus oropharynx colonization rates were observed and may warrant changes in decolonization practices.

Long-Lasting Cranial Nerve III Palsy as a Presenting Feature of Chronic Inflammatory Demyelinating Polyneuropathy

Full Text Available We describe a patient with chronic inflammatory demyelinating polyneuropathy (CIDP in which an adduction deficit and ptosis in the left eye presented several years before the polyneuropathy. A 52-year-old man presented with a 14-year history of unremitting diplopia, adduction deficit, and ptosis in the left eye. At the age of 45 a mild bilateral foot drop and impaired sensation in the four limbs appeared, with these symptoms showing a progressive course. The diagnostic workup included EMG/ENG which demonstrated reduced conduction velocity with bilateral and symmetrical sensory and motor involvement. Cerebrospinal fluid studies revealed a cytoalbuminologic dissociation. A prolonged treatment with corticosteroids allowed a significant improvement of the limb weakness. Diplopia and ptosis remained unchanged. This unusual form of CIDP presented as a long-lasting isolated cranial nerve palsy. A diagnostic workup for CIDP should therefore be performed in those patients in which an isolated and unremitting cranial nerve palsy cannot be explained by common causes.

Mastopexy and reduction mammaplasty are often limited by the patient's poor native soft tissue quality, resulting in ptosis recurrence and loss of rejuvenated surgical results. Surgical scaffolds and acellular dermal matrices are used in these procedures to provide physical and mechanical stabilization of weakened or compromised tissue. GalaFLEX scaffold, made from poly-4-hydroxybutyrate (P4HB), is a next-generation product for soft tissue reinforcement that resorbs gradually while aiding tissue regeneration to achieve excellent outcomes. To assess the clinical performance of GalaFLEX scaffold in soft tissue reinforcement during elective mastopexy and reduction mammaplasty. This multicenter, single-arm, observational study assessed product performance and outcomes of GalaFLEX scaffold when used in breast surgery. Outcomes included ptosis correction and maintenance, associated adverse events, patient and surgeon satisfaction, and mammographic and ultrasound imaging evaluation. At 6 centers in the US, 62 of 69 enrolled patients were treated. Of this population, 89.7% had successful ptosis correction and maintenance at 1 year, with high patient and surgeon satisfaction for breast shape, droop/sag of the breast, and maintenance of results at 1 year. There were 5 adverse events deemed related to the device (8.0%), including nerve pain, breast swelling, ptosis, and 2 instances of asymmetry. GalaFLEX scaffold safely and successfully supports and elevates breast tissue in mastopexy and reduction mammaplasty, with maintained support at 1 year. Surgeon and patient satisfaction were high. No mammogram or ultrasound interference was detected.

Effect of upper airway CO2 pattern on ventilatory frequency in tegu lizards.

Science.gov (United States)

Ballam, G O; Coates, E L

1989-07-01

Nasal CO2-sensitive receptors are reported to depress ventilatory frequency in several reptilian species in response to constant low levels of inspired CO2. The purpose of this study was to determine the influence of phasic patterns of CO2 in the upper airways on ventilation. Awake lizards (Tupinambis nigropunctatus) breathed through an endotracheal tube from an isolated gas source. A second gas mixture was forced at constant flow into the external nares. A concentration of 4% CO2 was intermittently pulsed through the nares in a square-wave pattern with a frequency of 60, 12, 6, 4.2, 1.8, and 0.6 cycles/min. Concentrations of 2, 3, 4, and 6% CO2 were also pulsed through the nares at 12 cycles/min and compared with sustained levels of 1, 1.5, 2, and 3%. Additionally, 0 or 3% CO2 was forced through the upper airways with a servo system designed to mimic normal ventilatory flow and gas concentrations. No changes in breathing pattern were noted during any of the pulsing protocols, although a significant breathing frequency depression was present with sustained levels of CO2 of comparable mean concentrations. We conclude that ventilatory control is selectively responsive to sustained levels of environmental CO2 but not to phasic changes in upper airway CO2 concentration.

During a recent survey for West Nile virus in wild birds around the Sonny Bono Salton Sea National Wildlife Refuge, Imperial County, California (Dusek et al. 2010), we captured a female American Kestrel (Falco sparverius) with a severe bill deformity (Figure 1). The kestrel was captured on 9 March 2006, at 08:45, approximately 0.25 km south of the intersection of Wiest and Lindsey roads (33°  08' 42' N, 115° 26' 59' W) and 6 km east-northeast of Calipatria. It was caught on a bal-chatri trap baited with a domestic mouse (Berger and Mueller 1959), as were all the 208 kestrels captured during this study. The bird was initially perched on a high transmission line running along Wiest Road and was caught within 10 minutes of our setting the trap. In examining the bird, we observed that the maxilla beyond the cere was missing. The upper bill structure from the palatine process, which included part of the maxilla, the entire premaxilla, and the external rhamphotheca (the hardened keratin layer cover­ ing the premaxilla) was missing rostral to the bird's cere and nares (Threlfall 1968, Lucas and Stettenheim 1972, Proctor and Lynch 1993). The epidermal layer of the cere appeared to have fused over the remaining area between the nares where the upper bill normally would have been. The deformation did not appear to be recent or related to our trapping, as there were no obvious abrasions or open wounds in the region surrounding the nares and oropharynx or signs of recent trauma surrounding the oropharynx area. Both nares were clearly defined, and the tongue protruded from the open oropharynx area. After completing the physical examination, measurements, and obtaining a blood sample for testing for West Nile virus, we released the kestrel at the location of capture. After its release, we monitored the kestrel's behavior for approximately 30 minutes but did not observe any additional hunting.

remains unclear whether colonization of atopic patients by Staphylococcus aureus (S. aureus through breastfeeding is relevant to the development of AD. OBJECTIVE: To examine the potential relation between breastfeeding and colonization by S. aureus in atopic patients. METHOD: Transversal study of atopic patients, aged from 4 to 24 months, both genders, receiving outpatient care and 72 mothers. Data on infant breastfeeding practices and on clinical-epidemiological profile were registered. Swabs of the infants' nares and skin (cubital fossa and swabs of the mothers' nares were collected. For univariate analysis, X2 (chi-square and Fischer Exact's test were used. RESULTS: Among breastfed children, S. aureus was isolated from 8 (25.8% infants' nares swabs and from 4 (12.9% skin swabs. Among not breastfed children, S. aureus was isolated from 10 (20.8% infants' nares swabs and from 11 (22.9% skin swabs. Sixteen mothers (22.2% had S. aureus isolated from their nares swabs. There was no significant association between breastfeeding and S. aureus colonization (child skin and/or nares. However, there was a degree of concordance for S. aureus carriage among mothers and infants. Among 72 pairs, 56 (77.8% were concordant. CONCLUSION: Breastfeeding was not associated with S. aureus muco-cutaneous colonization in atopic infants

To examine effects of atipamezole on detomidine midsacral subarachnoidally-induced analgesia, cardiovascular and respiratory activity, head ptosis, and position of pelvic limbs in healthy mares. 10 healthy mares. Using a randomized, blinded, crossover study design, mares received detomidine (0.03 mg/kg of body weight, diluted in 3 ml of CSF) midsacral subarachnoidally, followed by atipamezole (0.1 mg/kg [test]) or sterile saline (0.9% NaCl) solution (control), i.v. 61 minutes later and saline solution (3 ml, midsacral subarachnoidally) on a separate occasion, at least 2 weeks later. Analgesia was determined by lack of sensory perception to electrical stimulation at the perineal dermatome and no response to needle-prick stimulation extending from the coccygeal to T15 dermatomes. Arterial acid-base (pH, standard bicarbonate, and base excess values), gas tensions (PO2, PCO2), PCV, total solids concentration, heart and respiratory rates, rectal temperature, and arterial blood pressure were determined, and mares were observed for sweating and urination. Mean scores of perineal analgesia, head ptosis, position of pelvic limbs, and cardiovascular and respiratory data were compared for the 3-hour test period. Subarachnoidally administered detomidine induced perineal analgesia (mean +/- SD onset, 9.0 +/- 4.6 minutes; duration, 130 +/- 26 minutes), marked head ptosis, moderate changes in pelvic limb position, cardiovascular and respiratory depression, sweating in analgesic zones, and diuresis. Intravenously administered atipamezole significantly reduced mean scores of detomidine-induced perineal analgesia, head ptosis, pelvic limb position, sweating and diuresis; partially antagonized detomidine-induced bradycardia; and did not effect detomidine-induced bradypnea. Most effects of midsacral subarachnoidally administered detomidine, except bradycardia and bradypnea, were reversed by atipamezole (0.1 mg/kg, i.v.), indicating that most of the actions of detomidine were mediated

Full Text Available Ocular trauma can be caused by road traffic accidents, falls, assaults, or work-related accidents. Enucleation is often indicated after ocular injury or for the treatment of intraocular tumors, severe ocular infections, and painful blind eyes. Rehabilitation of an enucleated socket without an intraocular implant or with an inappropriately sized implant can result in superior sulcus deepening, enophthalmos, ptosis, ectropion, and lower lid laxity, which are collectively known as post-enucleation socket syndrome. This clinical report describes the rehabilitation of post-enucleation socket syndrome with a modified ocular prosthesis. Modifications to the ocular prosthesis were performed to correct the ptosis, superior sulcus deepening, and enophthalmos. The rehabilitation procedure produced satisfactory results.

Full Text Available The objective of this study was to find the prevalence of Staphylococcus spp. carriage among hospital personnel and hospital environment and their antibiogram with special emphasis on methicillin resistance. A total of 205 samples from hospital personnel and environment were collected from casualty, oncology and multidisciplinary cardiac unit ward of Kasturba Medical College Hospital, Manipal. Samples were collected using sterile cotton wool swabs and inoculated into brain heart infusion broth. Subcultures were done onto blood agar and MacConkey′s agar. Isolates were identified by standard methods up to species level. Antimicrobial susceptibility test was performed according to standardized disc diffusion Kirby-Bauer method. Each of the isolates was screened for methicillin resistance using oxacillin disc on Mueller Hinton agar plate followed by MIC for methicillin and cefoxitin susceptibility test by disc diffusion method. Sixty five out of 205 strains (31.7% were Staphylococcus spp. and all of them were coagulase negative. Most of the strains belonged to S.epidermidis 49.23%(32/65 followed by S. saprophyticus 26.15%(17/65. Maximum isolates of S.epidermidis were from anterior nares 28.12%(9/32 strains of S.epidermidis . Highest number of methicillin resistant coagulase negative strains (3/9, 33.33% were isolated from stethoscope of multidisciplinary cardiac unit ward followed by carriers in the anterior nares (2/9, 22.22%. Methicillin resistant coagulase negative staphylococci are prevalent in anterior nares of hospital personnel and in the hospital environment thereby providing a definite source for hospital acquired infection. All isolates were sensitive to vancomycin, ciprofloxacin and amikacin.

The aim of this study was to estimate the optimal depth of nasotracheal tube placement. We enrolled 110 patients scheduled to undergo oral and maxillofacial surgery, requiring nasotracheal intubation. After intubation, the depth of tube insertion was measured. The neck circumference and distances from nares to tragus, tragus to angle of the mandible, and angle of the mandible to sternal notch were measured. To estimate optimal tube depth, correlation and regression analyses were performed using clinical and anthropometric parameters. The mean tube depth was 28.9 ± 1.3 cm in men (n = 62), and 26.6 ± 1.5 cm in women (n = 48). Tube depth significantly correlated with height (r = 0.735, P < 0.001). Distances from nares to tragus, tragus to angle of the mandible, and angle of the mandible to sternal notch correlated with depth of the endotracheal tube (r = 0.363, r = 0.362, and r = 0.546, P < 0.05). The tube depth also correlated with the sum of these distances (r = 0.646, P < 0.001). We devised the following formula for estimating tube depth: 19.856 + 0.267 × sum of the three distances (R 2 = 0.432, P < 0.001). The optimal tube depth for nasotracheally intubated adult patients correlated with height and sum of the distances from nares to tragus, tragus to angle of the mandible, and angle of the mandible to sternal notch. The proposed equation would be a useful guide to determine optimal nasotracheal tube placement.

Gynecomastia Management: An Evolution and Refinement in Technique at UT Southwestern Medical Center

Bailey, Steven H.; Guenther, Dax; Constantine, Fadi

2016-01-01

Summary: Gynecomastia is a benign proliferation of male breast glandular tissue. Gynecomastia can affect men at any stage of life. Traditional treatment options involved excisional surgeries with periareolar or T-shaped scars, which can leave more visible scars on the chest. The technique presented represents a technique used by the senior author, which relies on ultrasonic liposuction and pull-through technique to remove breast tissue. A retrospective chart review was performed, including all patients who were treated, from 2000 to 2013 by the senior author, for gynecomastia. A deidentified database was created to record patient characteristics, including age, height, weight, ptosis, stage of gynecomastia, and gynecomastia classification. Surgical approaches, complications, and revisions were also recorded. Our experience includes 75 patients with all grades of gynecomastia from 2000 to 2013. These cases span the evolution of our technique to include direct pull-through excision with ultrasound-assisted liposuction. The distribution of the grades I, II, III, and IV ptosis was 30.6%, 36 %, 22.6%, and 10.6% respectively. There were no complications in this series. Only one patient with grade III ptosis required revision surgery. This technique provides a safe and aesthetically pleasing way to treat gynecomastia with a low need for revision. PMID:27482482

Clinical predictors for myasthenia gravis relapse and ocular myasthenia gravis secondary generalization during the first two years after disease onset remain incompletely identified. This study attempts to investigate the clinical predictors for the prognosis of Myasthenia Gravis. Eighty three patients with myasthenia gravis were concluded in this study. Baseline characteristics were analyzed as predictors. Relapse of myasthenia gravis developed in 26 patients (34%). Generalization developed in 34 ocular myasthenia gravis patients (85%). Other autoimmune diseases were observed more commonly in relapsed myasthenia gravis (P = 0.012). Second generalization group contained more late onset patients (P = 0.021). Ocular myasthenia gravis patients with thymus hyperplasia progressed more rapidly than those with other thymus pathology (P = 0.027). Single onset symptom of ocular myasthenia gravis such as ptosis or diplopia predicted early progression than concurrence of ptosis and diplopia (P = 0.027). Treatment effect including glucocorticoid, pyridostigmine, thymectomy, IVIG, immunosuppressive drugs did not show significant difference between the relapsed and non-relapsed groups. The treatment outcome also showed no difference between the single OMG and second generalized groups. Occurrence of associated autoimmune disease can serve as a potential predictor for myasthenia gravis relapse. Either ptosis or diplopia, as well as thymic hyperplasia can predict generalization in the first six months.

The Nance-Horan syndrome (NHS) is an infrequent X-linked disorder typified by dense congenital central cataracts, microcornea, anteverted and simplex pinnae, brachymetacarpalia, and numerous dental anomalies. The regional location of the genetic mutation causing NHS is unknown. The authors applied the modern molecular techniques of analysis of restriction fragment length polymorphisms to five multigenerational kindreds in which NHS segregated. Provisional linkage is established to two DNA markers--DXS143 at Xp22.3-p22.2 and DXS43 at Xp22.2. Regional localization of NHS will provide potential antenatal diagnosis in families at risk for the disease and will enhance understanding of the multifaceted genetic defects.

Full Text Available INTRODUCCIÓN. La mayor desventaja de la corrección de la hipertrofia mamaria moderada o la normotrofia asociadas a ptosis de grado I y II reside en las cicatrices visibles. Este trabajo buscó evaluar los resultados de una técnica de plastia mamaria de reducción y suspensión, por vía periareolar. MÉTODOS. En el Servicio de Cirugía Plástica del Hospital Clinicoquirúrgico «Hermanos Ameijeiras» fueron operadas 24 pacientes a las que se les realizó mastoplastia por vía periareolar. La técnica consistió en el diseño de un colgajo dermograso glandular fijado a la aponeurosis clavipectoral, mediante una incisión circular periareolar, de modo que la mama mantuviera su forma, consistencia y posición. RESULTADOS. Los resultados se evaluaron entre el primer, tercer y sexto mes después de la operación y al año de esta. En el 79,2 % de las pacientes se obtuvieron resultados estéticos. Se corrigió la ptosis mamaria en el 95,7 % de los casos y se logró una proyección anterior de la mama adecuada en el 87,5 % de las pacientes. Solo hubo complicaciones en tres casos y consistieron en lipólisis abscedada y necrosis de la piel. CONCLUSIONES. Con la técnica empleada se lograron buenos resultados estéticos en la mayoría de las pacientes, así como la corrección y reducción de la ptosis y volumen mamario respectivamente, con un mínimo de complicaciones leves.INTRODUCTION.

Full Text Available A 39-year-old Malay gentleman was presented with sudden onset of blurring of vision, associated with pain, redness and partial ptosis in the left eye (LE for 2 weeks. It was also associated with headache and drowsiness that were progressively worsened. On examination, the vision was hand movement LE. There was partial upper lid ptosis with injected conjunctiva and mild anterior chamber reaction. The view of the posterior segment was hazy on LE. The right eye was essentially normal. On investigation, B-scan ultrasound was suggestive of LE vitreous opacity. CT scan and MRI of the orbit and brain showed multiple enhancing brain lesions. Toxoplasma IgG, anti-HCV and anti-HIV were reactive and the patient was treated with toxoplasma infection.

On 21 September, 1984, a mooring (NAP-2) was deployed at 23 0 14.5'N, 64 0 02.1'W with an approximate bottom depth of 5835 meters. This mooring contained 6 upward looking traps (at 720, 1420, 2870, 3785, 4770, 5780 meters) and two inverted traps (at 2900 and 4800 meters). This mooring was successfully recovered on 21 November, 1985. The details of this recovery and the samples are presented. On 22 November, 1985, another shorter trap mooring (NAP-3) was deployed. The mooring was similar in design to NAP-1 and has two normal traps at 750 and 4800 meters and an inverted trap at 4830 meters

The sediment trap NAP-1 was successfully recovered and the materials have been analyzed for a set of bio- and geochemical components. The trap mooring NAP-2 was deployed and recovered but no analyses have been completed. The bulk fluxes are relatively low at this site and are approximately 50% biogenic and 50% terrigenous. The flux of terrigenous material is very high due to primary atmospheric inputs and horizontal transport of resuspended sediments. The buoyant particle fluxes are also extremely low. The accumulation of material in the sediments reflects the crustal nature of the vertical flux and also shows the normal loss of labile biogenic phases

The human nasal microbiota and Staphylococcus aureus carriage.

Directory of Open Access Journals (Sweden)

Daniel N Frank

Full Text Available BACKGROUND: Colonization of humans with Staphylococcus aureus is a critical prerequisite of subsequent clinical infection of the skin, blood, lung, heart and other deep tissues. S. aureus persistently or intermittently colonizes the nares of approximately 50% of healthy adults, whereas approximately 50% of the general population is rarely or never colonized by this pathogen. Because microbial consortia within the nasal cavity may be an important determinant of S. aureus colonization we determined the composition and dynamics of the nasal microbiota and correlated specific microorganisms with S. aureus colonization. METHODOLOGY/PRINCIPAL FINDINGS: Nasal specimens were collected longitudinally from five healthy adults and a cross-section of hospitalized patients (26 S. aureus carriers and 16 non-carriers. Culture-independent analysis of 16S rRNA sequences revealed that the nasal microbiota of healthy subjects consists primarily of members of the phylum Actinobacteria (e.g., Propionibacterium spp. and Corynebacterium spp., with proportionally less representation of other phyla, including Firmicutes (e.g., Staphylococcus spp. and Proteobacteria (e.g. Enterobacter spp. In contrast, inpatient nasal microbiotas were enriched in S. aureus or Staphylococcus epidermidis and diminished in several actinobacterial groups, most notably Propionibacterium acnes. Moreover, within the inpatient population S. aureus colonization was negatively correlated with the abundances of several microbial groups, including S. epidermidis (p = 0.004. CONCLUSIONS/SIGNIFICANCE: The nares environment is colonized by a temporally stable microbiota that is distinct from other regions of the integument. Negative association between S. aureus, S. epidermidis, and other groups suggests microbial competition during colonization of the nares, a finding that could be exploited to limit S. aureus colonization.

Gynecomastia Classification for Surgical Management: A Systematic Review and Novel Classification System.

Science.gov (United States)

Waltho, Daniel; Hatchell, Alexandra; Thoma, Achilleas

2017-03-01

Gynecomastia is a common deformity of the male breast, where certain cases warrant surgical management. There are several surgical options, which vary depending on the breast characteristics. To guide surgical management, several classification systems for gynecomastia have been proposed. A systematic review was performed to (1) identify all classification systems for the surgical management of gynecomastia, and (2) determine the adequacy of these classification systems to appropriately categorize the condition for surgical decision-making. The search yielded 1012 articles, and 11 articles were included in the review. Eleven classification systems in total were ascertained, and a total of 10 unique features were identified: (1) breast size, (2) skin redundancy, (3) breast ptosis, (4) tissue predominance, (5) upper abdominal laxity, (6) breast tuberosity, (7) nipple malposition, (8) chest shape, (9) absence of sternal notch, and (10) breast skin elasticity. On average, classification systems included two or three of these features. Breast size and ptosis were the most commonly included features. Based on their review of the current classification systems, the authors believe the ideal classification system should be universal and cater to all causes of gynecomastia; be surgically useful and easy to use; and should include a comprehensive set of clinically appropriate patient-related features, such as breast size, breast ptosis, tissue predominance, and skin redundancy. None of the current classification systems appears to fulfill these criteria.

Studies of malformation syndromes in man XXXX: multiple congenital anomalies/mental retardation syndrome or variant familial developmental pattern; differential diagnosis and description of the McDonough syndrome (with XXY son from XY/XXY father).

Science.gov (United States)

Neuhäuser, G; Opitz, J M

1975-11-13

The McDonough syndrome is a "new" MCA/MR syndrome which was found in 3 children (1 girl, 2 boys) of non-consanguineous parents. The affected children were mentally retarded (IQ 47--67) and had congenital heart defect, sternal deformity, kyphosis and craniofacila anomalies (anteverted auricles, upward slanted palpebral fissures, squint); cryptorchidism was present in the 2 boys. In addition a possible VFDP is postulated as the explanation for similar features in affected and unaffected siblings and parents. However, the McDonough syndrome may be an autosomal recessive trait with minor manifestations in heterozygotes. The klinefelter syndrome in one affected boy and a 46,XY/47,XXY chromosome constitution in the father was a coincidental finding.

Full Text Available Introduction: The aim of this study was to evaluate the efficacy of acupuncture therapy on relieving ocular symptoms in resistant Ocular Myasthenia Gravis (OMG. Case: In this pilot study, three patients with OMG were offered ten sessions of acupuncture therapy, twice weekly, while they received their routine medical treatment. Their symptoms included ptosis and diplopia. Subjective impression of changes was assessed based on Ocular-quantitative Myasthenia Gravis (QMG scoring before and after treatment sessions. Conclusion:All three patients enrolled in this study showed resolution of diplopia. Their subjective impression of symptoms was improved. However, the score of ptosis did not improve considerably. Acupuncture is another choice for reducing ocular symptoms besides conventional treatment in resistant Ocular Myasthenia Gravis (OMG. However, future randomized controlled trial studies are needed to approve this issue.

[What would you do in front of a patient with a Horner syndrome?

Horner's syndrome (HS) occurs when there is disruption to the oculosympathetic pathway. Its features include eyelid ptosis, miosis and anhidrosis. The aetiology of this syndrome is varied and includes tumours, trauma, vascular disease and iatrogenic. Different pharmacologic tests are used for diagnosis, such as cocaine, hydroxyamphetamine and apraclonidine; while neuroimaging helps elucidating the aetiology. We present a case of a 63-year-old female referred to our service with a 4-month history of right eyelid ptosis. During examination right miosis was noted. The patient reported a history of multinodular goiter. Pharmacologic tests and neuroimaging confirmed the diagnosis of HS secondary to thyroid disease.

Delivering heated and humidified medical gas at 20-60 L/min, high-flow nasal cannula (HFNC) creates low levels of PEEP and ameliorates respiratory mechanics. It has become a common therapy for patients with respiratory failure. However, independent measurement of heat and humidity during HFNC and comparison of HFNC devices are lacking. We evaluated 2 HFNC (Airvo 2 and Optiflow system) devices. Each HFNC was connected to simulated external nares using the manufacturer's standard circuit. The Airvo 2 outlet-chamber temperature was set at 37°C. The Optiflow system incorporated an O2/air blender and a heated humidifier, which was set at 40°C/3. For both systems, HFNC flow was tested at 20, 40, and 50 L/min. Simulating spontaneous breathing using a mechanical ventilator and TTL test lung, we tested tidal volumes (VT) of 300, 500, and 700 mL, and breathing frequencies of 10 and 20 breaths/min. The TTL was connected to the simulated external nares with a standard ventilator circuit. To prevent condensation, the circuit was placed in an incubator maintained at 37°C. Small, medium, and large nasal prongs were tested. Absolute humidity (AH) of inspired gas was measured at the simulated external nares. At 20, 40, and 50 L/min of flow, respective AH values for the Airvo 2 were 35.3 ± 2.0, 37.1 ± 2.2, and 37.6 ± 2.1 mg/L, and for the Optiflow system, 33.1 ± 1.5, 35.9 ± 1.7, and 36.2 ± 1.8 mg/L. AH was lower at 20 L/min of HFNC flow than at 40 and 50 L/min (P 30 mg/L.

AIM: To report a case of superior orbital fissure syndrome (SOFS) in a patient with herpes zoster ophthalmicus (HZO). MATERIALS AND METHODS: A case report. RESULTS: A 71-year-old male with HZO presented acutely to accident and emergency complaining of right vision loss, double vision and drowsiness. The right visual acuity was counting fingers. There was no relative afferent pupillary defect. He had interstitial keratitis, ptosis, proptosis and total ophthalmoplaegia. The signs indicated HZO complicated by SOFS. Brain imaging and lumbar puncture confirmed the diagnosis of varicella zoster encephalitis. Systemic acyclovir and prednisolone led to recovery of visual acuity and ocular motility in addition to resolution of his proptosis and ptosis. CONCLUSION: SOFS is a rare complication of herpes zoster infection. With the appropriate treatment and follow-up, patients may be reassured that recovery of their visual acuity and ocular motility will occur.

2006-01-01

Both hypergonadotropic hypogonadism and myasthenia gravis can be parts of type II autoimmune polyendocrine syndrome and association between the two disorders has been reported in few cases. A 14 year old male patient with a personal history of bilateral cryptorchidism and ptosis was referred for delayed puberty. Clinical examination revealed eunuchoid habitus, small, soft testes, gynecomastia, ptosis, a myasthenic deficit score of 22.5 points and an IQ of 84 points. Decreased testosterone (0.064 ng/mL) and elevated LH (64.5 mUI/mL) were consistent with hypergonadotropic hypogonadism and karyotype was normal: 46,XY. Thyroid function, haematologic evaluation, BUN, electrolytes, and glycemia were in the normal range. Therapy consisted of anticholinesterase inhibitors, immunosuppressants, corticotherapy, testosterone; thoracoscopic thymectomy was performed showing thymic lymphoid hyperplasia on histopathologic examination. Myasthenic score improved (12.5 points), progressive virilization occurred, and a year later the patient presented with cushingoid features and obesity.

The Phenylephrine Test Revisited.

Science.gov (United States)

Barsegian, Arpine; Botwinick, Adam; Reddy, Harsha S

To characterize the phenylephrine test in ptotic patients to help clinicians perform the test more efficiently. Adults with involutional ptosis (n = 24, 30 eyes) were assessed with digital photographs for response to topical 2.5% phenylephrine drop instillation. Patient characteristics (age, gender, iris color, dermatochalasis, brow ptosis, and baseline marginal reflex distance-1 [MRD-1] height) were recorded. From the photographs, change in (MRD-1), presence of conjunctival blanching, pupillary dilation, and Hering effect were recorded at specified time intervals, 1 minute to 1 hour after drop placement. Correlations between patient characteristics and measured outcomes were evaluated using analysis of variance, Pearson coefficient, or chi-square tests. The authors found that 73% of eyes had eyelid elevation with phenylephrine. Of these, 50% reached maximal eyelid elevation by 5 minutes, and 86% by 10 minutes after drop placement, but 14% did not reach maximal MRD-1 until 30 minutes. There is a negative correlation between the maximum MRD-1 and the baseline MRD-1 eyelid height (r = -0.5330, p patient characteristic studied affected the likelihood of eyelid response to phenylephrine or presence of Hering effect. Although most ptotic eyelids demonstrate a response to 2.5% phenylephrine within 10 minutes, there is a subset of patients that respond much later. More ptotic eyelids had greater eyelid elevation with phenylephrine. Pupillary dilation and conjunctival blanching are neither predictive of nor temporally associated with eyelid height elevation. The authors did not identify any patient factors (e.g., dermatochalasis, brow ptosis) that can predict the likelihood of response to phenylephrine.

Sehgal, Shekhar; Rebello, Roshan; Wolmarans, Louise; Elston, Marianne

2017-09-07

We present two patients with Graves' disease and concurrent myasthenia gravis. The impact of the dual diagnosis on the clinical course and the potential for a delayed diagnosis of myasthenia gravis is discussed. Patient 1, a 28-year-old man was diagnosed with Graves' disease following his second respiratory arrest. His history was strongly suggestive of a second pathology. Patient 2, a 66-year-old Cantonese woman with established Graves' disease presented with thionamide-related neutropaenia. Examination revealed bilateral ptosis and right lateral rectus palsy. Both patients had thyrotoxicosis secondary to Graves' disease with concurrent myasthenia gravis. Although neuromuscular weakness is common in Graves' disease, coexisting myasthenia gravis (MG) is rare and can cause profound morbidity. Ocular signs in both diseases may cause diagnostic confusion although ptosis suggests coexisting MG. In both cases, the thyrotoxicosis delayed the diagnosis of MG. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

Karim, A; Schapiro, D; Morax, S

2003-01-01

Steinert myopathic dystrophy is a generalized, hereditary disease with bone, muscular, heart and ocular involvement. This is a retrospective study of nine patients with significant blepharoptosis due to Steinert disease, who were treated at the Adolphe de Rothschild Ophthalmology Foundation over a period of 5 years. Ptosis was symmetric and major in all cases with poor levator excursion. Severity criteria were an absence of the Bell phenomenon and diminished orbicularis tone. A frontalis suspension was performed in eight cases with intentional undercorrection. The outcome was favorable in all cases, 2 with a slight overcorrection underwent a second operation conclusion: Surgical treatment of ptosis in Steinert disease is difficult because of a risk of lagophthalmic, keratopathy due to the severity of the disease, an absence of the Bell phenomenon and ophthalmoplegia. This surgery must be undertaken with caution, most often using a frontalis suspension. Undercorrection must be systematic, with the single goal of freeing the pupil in the primary position.

Unusual case of persistent Horner′s syndrome following epidural anaesthesia and caesarean section

Shubhra Goel

2011-01-01

Full Text Available This is a rare case of persistent Horner′s syndrome following epidural anesthesia and Caesarean section. A 33-year-old female presented with persistent ptosis and miosis following epidural anesthesia and Caesarian section several months prior. Magnetic resonance imaging (MRI/magnetic resonance angiography (MRA of head, neck, and chest were unremarkable. Medline search using terms Horner′s, epidural, spinal anesthesia, delivery, childbirth, Caesarian, and pregnancy identified 31 articles describing Horner′s syndrome in obstetric epidural anesthesia, of which 11 were following Caesarean section. The increased incidence of Horner′s syndrome in the setting of epidural anesthesia in pregnancy may be related to epidural venous engorgement and cephalic spread of the local anaesthetic, with disruption in the oculosympathetic pathway. It is important to include recent epidural anesthesia within the differential diagnosis of acute Horner′s syndrome in a postpartum female. Rarely, the ptosis may be permanent and require surgical intervention.

Neurogenic Bladder in Lyme Disease

Full Text Available Lyme disease is a multi-systemic, tick-borne infectious disease caused by a spirochete, Borrelia burgdorferi. Various urologic symptoms are associated with Lyme disease, which can be primary or late manifestations of the disease. Although voiding dysfunction is a rarely reported symptom in patients with Lyme disease, it is one of the most disabling complications of Lyme disease. Korea is not an endemic area of Lyme disease, thus, fewer cases have been reported. Herein, we report a case of a 32-year-old man with rapidly progressive bilateral ptosis, dysphagia, spastic paraparesis, and voiding difficulty in whom Lyme disease was diagnosed through serologic tests for antibodies and Western blot testing. A urodynamic study demonstrated detrusor areflexia and bulbocavernosus reflex tests showed delayed latency, indicating demyelination at S2-S4 levels. He received a 4-week course of intravenous ceftriaxone (2 g/day. The patient has recovered from the bilateral ptosis and spastic paraparesis but still suffers from neurogenic bladder.

"Ptosis" by Guadalupe Nettel and other stories about violence

Directory of Open Access Journals (Sweden)

Maricruz Castro Ricalde

2017-07-01

Full Text Available The vast amount of published narratives on the last decade in Mexico, linked to an unnerving social climate produced by drug trafficking and corruption, is highly noticeable. In response to these sociopolitical conditions, it seems to me that the stories that don´t approach violence directly should be questioned. Here I pose that oblique writing is a form of resisting the possibility that violence is being nurtured from language. In this article I focus on “Ptosis”, one of the short stories in Pétalos y otras historias incómodas (2008 by Guadalupe Nettel. Appealing to the theoretical approaches of Ariel Dorfman, Amartya Sen, Arjun Appadurai, Walter Benjamin, and Roland Barthes, and others, I aim to reflect on the nature of identities and their survival methods, in the midst of a violence social context.

Nenhum paciente do grupo II apresentou incremento da fenda palpebral após o teste. CONCLUSÃO: O teste do gelo mostrou-se específico para detecção de ptose palpebral de causa miastênica.PURPOSE: To demonstrate the sensitivity and the specificity of the ice test in the differential diagnosis of ptosis in myasthenia gravis. METHODS: Prospective trial with a control group. The patients were instructed to hold a frozen ice pack on the closed ptotic eyelid. They were divided into 2 groups, with group I consisting of patients with myasthenia gravis and group II (control consisting of patients with congenital, non-myasthenic myogenic or aponeurotic ptosis. RESULTS: All patients in group I had increased palpebral fissure for at least 3 mm after the application of ice pack. No patient in group II showed increased palpebral fissure after the ice test. CONCLUSION: Ice test proved to be specific for the detection of myasthenic ptosis.

Although reoperation rates for upper lid retraction surgery for thyroid eye disease (TED) typically range between 8% and 23%, there is little literature describing the outcomes of these second operations. In this retrospective observational cohort study, all patients that underwent surgery for upper eyelid retraction over a 14-year period at a single institution were included. Cases were included if a second eyelid retraction surgery was performed during the study period. Success of surgery was defined as a marginal reflex distance (MRD1) of 2.5 to 4.5 mm in each eye and less than 1 mm difference in MRD1 between the eyes. Overcorrection and undercorrection were defined as above and below these bounds, respectively. 72 eyes in 49 patients were included in the study. The mean age was 56.6 (±11.5) years. By definition, all patients had at least 1 lid lengthening surgery for upper eyelid retraction, and at least 1 subsequent surgery. For this second surgery, 61 eyes (85%) underwent retraction surgery and 11 eyes (15%) underwent ptosis surgery. After this second operation, 31% were undercorrected and 33% were overcorrected. A third surgery was performed in 19 eyes (25%), 12 had surgery for residual retraction and 7 for ptosis. After the third operation 10% of eyes were under corrected and 11% were over corrected. Four patients underwent a fourth surgery: one for retraction and three for ptosis. Success was noted in 35% after the second surgery and 44% after the third. Surgical success in eyelid retraction surgery increases from a second to a third consecutive surgery, and residual asymmetry was roughly equally distributed between over- and undercorrection.

The aim of this study was to demonstrate the characteristics of sticky eyelid syndrome (SES) and to suggest a modified definition and new classification of the disease in relation to the severity of the syndrome in East Asian patients. Forty-four eyes of 31 patients with sticky eyelid syndrome were included in this study. The medical records of patients who were diagnosed with sticky eyelid syndrome were retrospectively reviewed. Sticky eyelid syndrome was defined as an abnormal adhesion between the upper and lower eyelids during blinking. We divided the subjects into four grades according to the severity of the disease. Among 31 patients, there were 10 men and 21 women. The mean age of patients was 62.5 years. A total of 13 patients had SES bilaterally. All patients had meibomian gland dysfunction (MGD). Thirty-three eyes had dermatochalasis, and 30 eyes had involutional ptosis. Horizontal lower lid laxity was observed in 23 eyes, and reverse ptosis found in 15 eyes. Patients were classified into four groups as follows: G1: 11 (25%), G2: 24 (54.5%), G3: 6 (13.6%) and G4: 3 eyes (6.8%). Patients in Grade 1 tended to improve only with medical treatment for MGD. However, surgical management was necessary for patients in Grades 3 and 4. Meibomian gland dysfunction is a fundamental risk factor for developing sticky eyelid syndrome. Further, combined upper lid ptosis or lower lid laxity may be aggravating factors. According to the grading, medical or surgical management can be chosen. © 2014 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

Objective assessment of quality of life in female patients after esthetic, non-oncologic or oncologic surgery of their mammary glands--reality and perspectives.

The World Health Organisation defines health as a state of complete physical, mental and social well-being, and not merely the absence of a disease or infirmity. The female breast, surgically considered as a "troubled organ", can be affected by disorders of various types. Its normal morphology can be changed by deformities which may have a serious impact on the mental state of female patients. Assessment of these deformities is essential when doctors should define the inclusion and exclusion criteria for each breast operation that has elements of esthetic surgery in it, the breast being indisputably a symbol of female beauty. When we consider the parameters of normal breast morphology, it is only proper to take into account their dependence on race, national culture, folk psychology, etc. For Bulgarian women, P. Tepavicharova has found that the distance from fossa jugularis to the nipple-areolar complex can have the following characteristic proportions: 15.5-17 cm for a woman 155-160 cm in height and with breast circumference of 75-80 cm; 17-18.5 cm for woman 160-165 cm in height and with breast circumference of 89-95 cm; and 18-20 cm for a woman 165-170 cm in height and with breast circumference of 95-100 cm. J. Lalardie points out that breast stability is determined by three principal factors: skin and its elasticity, the condition of the underlying collagenous structure of the breast, and the firm bond between the skin and fibrous elements. RB Brinks defines the four forms of ptosis of the breast: glandular ptosis, true ptosis, parenchymal maldistribution, and pseudoptosis. According to P. Tepavicharova, the violation of breast symmetry is the major factor triggering a sequence of psychosomatic reactions. The basic parameters of female breast morphology are the mammary base, mammary perimeter, the forward projection of the breast, symmetry, breast volume, and the state of the axillary extension. The major deviations from normal breast morphology that can have an

May, Elizabeth R; Kinyon, Joann M; Noxon, James O

2012-12-07

In veterinary medicine, Staphylococcus schleiferi was previously assumed to be an inhabitant of carnivore skin, however, more recently, it has been repeatedly documented in the literature as both an inhabitant and as a pathogen. In order to determine the frequency of nasal carriage, and the methicillin susceptibility pattern of S. schleiferi from healthy dogs as well as dogs with otitis and/or pyoderma, a prospective study including 24 dogs with healthy ears and skin, 27 dogs with healthy ears and pyoderma, 15 dogs with otitis without pyoderma and 20 dogs with both otitis and pyoderma was performed. Specimens were obtained and cultured and isolates were identified as S. schleiferi based on growth and biochemical characteristics. S. schleiferi was isolated from the nares of 1 healthy dog, 3 dogs with recurrent pyoderma, 2 dogs with recurrent otitis, and 1 dog with both recurrent otitis and pyoderma. One of the S. schleiferi isolates was methicillin resistant. Nasal carriage of S. schleiferi does occur in healthy dogs as well as dogs with otitis and pyoderma. Methicillin resistant and sensitive S. schleiferi can be found in the nares of dogs with diseased ears and skin. Copyright © 2012 Elsevier B.V. All rights reserved.

Spinosaur taxonomy and evolution of craniodental features: Evidence from Brazil.

Directory of Open Access Journals (Sweden)

Marcos A F Sales

Full Text Available Fossil sites from Brazil have yielded specimens of spinosaurid theropods, among which the most informative include the cranial remains of Irritator, Angaturama, and Oxalaia. In this work some of their craniodental features are reinterpreted, providing new data for taxonomic and evolutionary issues concerning this particular clade of dinosaurs. The mesial-most tooth of the left maxilla of the holotype of Irritator is regarded as representing the third tooth position, which is also preserved in the holotype of Angaturama. Thus, both specimens cannot belong to the same individual, contrary to previous assumptions, although they could have been the same taxon. In addition, the position of the external nares of Irritator is more comparable to those of Baryonyx and Suchomimus instead of other spinosaurine spinosaurids. In fact, with regards to some craniodental features, Brazilian taxa represent intermediate conditions between Baryonychinae and Spinosaurinae. Such a scenario is corroborated by our cladistic results, which also leave open the possibility of the former subfamily being non-monophyletic. Furthermore, the differences between spinosaurids regarding the position and size of the external nares might be related to distinct feeding habits and degrees of reliance on olfaction. Other issues concerning the evolution and taxonomy of Spinosauridae require descriptions of additional material for their clarification.

Nance-Horan syndrome (NHS) is a rare X-linked disorder typified by dense congenital central cataracts, microcornea, anteverted and simplex pinnae, brachymetacarpalia, and numerous dental anomalies due in most cases to a mutation in the NHS gene. We present a case of clinical manifestation and ocular pathology in a patient with NHS. This article also reviews and discusses the relevant literature. Classic and novel ocular pathological findings of a young male with NHS are described, including congenital cataracts, infantile glaucoma, scleral staphyloma, and severe retinal cystoid degeneration. We report a new pathological finding of severe retinal cystoid degeneration in this NHS patient and confirm abnormal development of the anterior chamber angle structure. These findings, coupled with our analysis of the available NHS literature, provide new understanding of the histopathological basis of ocular abnormalities and vision loss in NHS.

Full Text Available Primary non-Hodgkin’s lymphoma (NHL can arise from lymphatic cells located in solid organs (extranodal and it accounts for 25 to 35% of all NHL. Primary lymphoma on the female genital tract (PLFGT is a rare disease, comprising 0.2 to 1.1% of all extranodal lymphomas in the female population. In this paper, the authors report an extremely rare case of a 48-year-old woman who exhibited an abnormal uterine bleeding, pelvic pain, and dysmenorrhea history. The transvaginal ultrasound showed an anteverted uterus measuring 153 cm3 in volume, with intramural leiomyomas. She underwent a total laparoscopic hysterectomy with bilateral salpingectomy. The histologic evaluation of the specimen showed a follicular lymphoma with diffuse pattern in the endometrium. This report illustrates the difficulty in the diagnosis of primary lymphomas of the female genital tract.

Mamoplastia de aumento dinámica con control de vectores

Full Text Available La mamoplastia de aumento debe ser una cirugía segura, predecible, duradera, que mantenga la forma natural de las mamas, preserve la sensibilidad del complejo areola-pezón, no altere la lactancia, con mínima reacción al implante colocado, y que no interfiera con los estudios imagenológicos. Cuando las mamas presentan alguna deformidad asociada tipo ptosis, mamas tuberosas, etc, el emplear una combinación de técnicas brinda un mejor resultado final en comparación con el empleo de un procedimiento de aumento puro. Presentamos la técnica quirúrgica que empleamos desde el 2003 que a nuestro juicio cumple con todos estos objetivos y puede utilizarse para aumento mamario en pacientes con ptosis leve o moderada. Describimos la técnica con detalle y discutimos las indicaciones y ventajas de incorporar estos refinamientos técnicos a la mamoplastia de aumento convencional. Recogemos 230 casos en los que se realizó mamoplastia de aumento multiplanar con disección muscular ampliada en bloque, optimizando vectores independientes para reposicionar el complejo areola-pezón en su posición ideal en casos de ptosis asociada. Agregamos puntos de anclaje percutáneos en 98 pacientes para conseguir este efecto. No hemos tenido complicaciones mayores, más allá de pequeñas dehiscencias superficiales de las heridas en 18 casos que se corrigieron con tratamiento expectante sin dejar secuelas. Con esta técnica intentamos aportar una opción más al cirujano plástico para ofrecer un resultado natural y duradero a las pacientes que se someten a mamoplastia de aumento.

Trends in the Surgical Correction of Gynecomastia.

Science.gov (United States)

Brown, Rodger H; Chang, Daniel K; Siy, Richard; Friedman, Jeffrey

2015-05-01

Gynecomastia refers to the enlargement of the male breast due to a proliferation of ductal, stromal, and/or fatty tissue. Although it is a common condition affecting up to 65% of men, not all cases require surgical intervention. Contemporary surgical techniques in the treatment of gynecomastia have become increasingly less invasive with the advent of liposuction and its variants, including power-assisted and ultrasound-assisted liposuction. These techniques, however, have been largely limited in their inability to address significant skin excess and ptosis. For mild to moderate gynecomastia, newer techniques using arthroscopic morcellation and endoscopic techniques promise to address the fibrous component, while minimizing scar burden by utilizing liposuction incisions. Nevertheless, direct excision through periareolar incisions remains a mainstay in treatment algorithms for its simplicity and avoidance of additional instrumentation. This is particularly true for more severe cases of gynecomastia requiring skin resection. In the most severe cases with significant skin redundancy and ptosis, breast amputation with free nipple grafting remains an effective option. Surgical treatment should be individualized to each patient, combining techniques to provide adequate resection and optimize aesthetic results.

A Case of Brown-Vialetto-Van Laere Syndrome Due To a Novel Mutation in Gene

2017-08-01

Full Text Available Brown-Vialetto-Van Laere syndrome is a rare disorder characterized by motor, sensory, and cranial neuronopathies, associated with mutations in SLC52A2 and SLC52A3 genes that code for human riboflavin transporters RFVT2 and RFVT3, respectively. The authors describe the clinical course of a 6-year-old girl with Brown-Vialetto-Van Laere syndrome and a novel homozygous mutation c.1156T>C in the SLC52A3 gene, who presented at the age of 2.5 years with progressive brain stem dysfunction including ptosis, facial weakness, hearing loss, dysphagia, anarthria with bilateral vocal cord paralysis, and ataxic gait. She subsequently developed respiratory failure requiring tracheostomy and worsening dysphagia necessitating a gastrostomy. Following riboflavin supplementation, resolution of facial diplegia and ataxia, improvements in ptosis, and bulbar function including vocalization and respiration were noted. However, her sensorineural hearing loss remained unchanged. Similar to other cases of Brown-Vialetto-Van Laere syndrome, our patient responded favorably to early riboflavin supplementation with significant but not complete neurologic recovery.

2003-09-01

To evaluate the efficacy of endosaccular Guglielmi detachable coil (GDC) treatment of unruptured aneurysms causing cranial nerve (CN) symptoms. Among a database of 218 patients whose aneurysms were treated using GDC, seven patients met the criteria for unruptured aneurysms presenting with symptoms and signs of CN palsy. Changes in CN symptoms before and after GDC treatment were reviewed. Aneurysms were located in the internal carotid-posterior communicating artery (n=3), the basilar bifurcation (n=1) and the cavernous internal carotid artery (n=3). CN symptoms included ptosis (n=6), mydriasis (n=2), and extraocular muscle (EOM) disorder (CN III: n=4; CN VI: n=3). Overall, improvement or resolution of CN symptoms after treatment was noted in five patients. CN symptoms in cases involving small (10 mm) and intradural aneurysms tended to respond better to GDC treatment. Ptosis was the initial symptom to show improvement, while EOM dysfunction responded least favourably. GDC coil packing appears to be an appropriate treatment method for the relief of CN symptoms associated with intracranial aneurysms.

Presumed Isotretinoin-Induced, Concomitant Autoimmune Thyroid Disease and Ocular Myasthenia Gravis: A Case Report

2012-11-01

Full Text Available Introduction: There are many adverse effects that have been described for isotretinoin. To the best of our knowledge, this is the first report of a possible association of oral isotretinoin intake with autoimmune thyroiditis and ocular myasthenia gravis (OMG. Case Presentation: A 19-year-old Caucasian male, who had used oral isotretinoin for severe acne disease for the previous six months, was referred to our clinic. He had a three-week history of diplopia and variable bilateral ptosis. Physical examination showed moderate periorbital edema and limitations of up- and down-gaze in the left eye. Laboratory findings and thyroid ultrasound were consistent with autoimmune thyroiditis. Antithyroid therapy did not relieve the clinical symptoms. Concomitant OMG was suspected. Variable ptosis and a positive response to oral prednisolone of 40 mg/day and pyridostigmine of 360 mg/day supported the diagnosis of concomitant autoimmune thyroiditis and OMG. Conclusion: Autoimmune disorders may be triggered by oral isotretinoin treatment. Clinicians prescribing isotretinoin should be aware of the possible association between isotretinoin intake and concomitant autoimmune thyroiditis and OMG.

We present a case that suggests a relationship between primary biliary cirrhosis and myasthenia gravis. A 43-year-old Japanese woman was admitted to the Nagoya City University Medical School, First Department of Internal Medicine with abnormal liver function in August 1991. She had had ptosis of the right eye since 1990. She had not been treated for liver disease. Ptosis of the right eye and hepatomegaly were present. Serum laboratory examinations revealed elevated biliary enzymes and IgM levels; tests were positive for antimitochondrial antibody and antiacetylcholine antibody. Liver histology revealed chronic non-suppurative destructive cholangitis and led to a diagnosis of primary biliary cirrhosis. The tensilon test was positive. Electromyography with repetitive motor nerve stimulation revealed a neuromuscular junction defect; i.e., the primary characteristic of myasthenia gravis. The patient was diagnosed with myasthenia gravis. Although the development of myasthenia gravis has previously been reported in patients with primary biliary cirrhosis during D-penicillamine administration, this is a very rare case of the coexistence of both diseases before such treatment.

Conclusions: Large glandular specimen increases the risk of NAC necrosis. The degree of ptosis and the distance between the sternal notch and the NAC have no significant impact on necrotic complications in NSM. To reduce the necrotic complications in large breast after NSM, reconstruction should better be performed with autologous flap or slow skin expansion using the expander technique.

Ocean floor sediment as a repository barrier: comparative diffusion data for selected radionuclides in sediments from the Atlantic and Pacific Oceans

International Nuclear Information System (INIS)

Schreiner, F.; Sabau, C.; Friedman, A.; Fried, S.

1986-01-01

Effective diffusion coefficients for selected radionuclides have been measured in ocean floor sediments to provide data for the assessment of barrier effectiveness in subseabed repositories for nuclear waste. The sediments tested include illite-rich and smectite-rich red clays from the mid plate gyre region of the Pacific Ocean, reducing sediment from the continental shelf of the northwest coast of North America, and Atlantic Ocean sediments from the Southern Nares Abyssal Plain and the Great Meteor East region. Results show extremely small effective diffusion coefficients with values less than 10 -14 m 2 s -1 for plutonium, americium, curium, thorium, and tin. Radionuclides with high diffusion coefficients of approximately 10 -10 m 2 s - include the anionic species pertechnetate, TcO 4 - , iodide, I - , and selenite, SO 3 -2 . Uranyl(VI) and neptunyl(V) ions, which are stable in solution, have diffusion coefficients around 10 -12 m 2 s -1 . The diffusion behavior of most radionuclides is similar in the oxygenated Pacific sediments and in the anoxic sediments from the Atlantic. An exception is neptunium, which is immobilized by Great Meteor East sediment, but has high mobility in Southern Nares Abyssal Plain sediment. Under stagnant conditions a 30 m thick sediment layer forms an effective geologic barrier isolating radionuclides in a subseabed repository from the biosphere

Effective diffusion coefficients for selected radionuclides have been measured in ocean floor sediments to provide data for the assessment of barrier effectiveness in subseabed repositories for nuclear waste. The sediments tested include illite-rich and smectite-rich red clays from the mid-plate gyre region of the Pacific Ocean, reducing sediment from the continental shelf of the northwest coast of North America, and Atlantic Ocean sediments from the Southern Nares Abyssal Plain and the Great Meteor East region. Results show extremely small effective diffusion coefficients with values less than 10 -14 m 2 s -1 for plutonium, americium, curium, thorium, and tin. Radionuclides with high diffusion coefficients of approximately 10 -10 m 2 s -1 include the anionic species pertechnetate, TcO 4 - , iodide, I - , and selenite, SeO 3 -2 . Uranyl(VI) and neptunyl(V) ions, which are stable in solution, have diffusion coefficients around 10 -12 m 2 s -1 . The diffusion behavior of most radionuclides is similar in the oxygenated Pacific sediments and in the anoxic sediments from the Atlantic. An exception is neptunium, which is immobilized by Great Meteor East sediment, but has high mobility in Southern Nares Abyssal Plain sediment. Under stagnant conditions a 30 m thick sediment layer forms an effective geologic barrier isolating radionuclides in a subseabed repository from the biosphere. 13 refs., 5 figs., 1 tab

2015-01-01

Gynecomastia refers to the enlargement of the male breast due to a proliferation of ductal, stromal, and/or fatty tissue. Although it is a common condition affecting up to 65% of men, not all cases require surgical intervention. Contemporary surgical techniques in the treatment of gynecomastia have become increasingly less invasive with the advent of liposuction and its variants, including power-assisted and ultrasound-assisted liposuction. These techniques, however, have been largely limited in their inability to address significant skin excess and ptosis. For mild to moderate gynecomastia, newer techniques using arthroscopic morcellation and endoscopic techniques promise to address the fibrous component, while minimizing scar burden by utilizing liposuction incisions. Nevertheless, direct excision through periareolar incisions remains a mainstay in treatment algorithms for its simplicity and avoidance of additional instrumentation. This is particularly true for more severe cases of gynecomastia requiring skin resection. In the most severe cases with significant skin redundancy and ptosis, breast amputation with free nipple grafting remains an effective option. Surgical treatment should be individualized to each patient, combining techniques to provide adequate resection and optimize aesthetic results. PMID:26528088

To report a new technique for unilateral brow suspension for facial paralysis that is minimally invasive, limits supraciliary scar formation, does not require specialized endoscopic equipment or expertise, and has proved to be equal to direct brow suspension in durability and symmetry. Retrospective survey of a case series of 23 patients between January 1997 and December 2000. Metropolitan tertiary care center. Patients with head and neck tumors and brow ptosis caused by facial nerve paralysis. The results of the procedure were determined using the following 3-tier rating system: outstanding (excellent elevation and symmetry); acceptable (good elevation and fair symmetry); and unacceptable (loss of elevation). The results were considered outstanding in 12 patients, acceptable in 9 patients, and unacceptable in only 1 patient. One patient developed a hematoma, and 1 patient required a secondary adjustment. The technique has proved to be superior to standard brow suspension procedures with regard to scar formation and equal with respect to facial symmetry and suspension. These results have caused us to abandon direct brow suspension and to use this minimally invasive method in all cases of brow ptosis due to facial paralysis.

Rodriguez, Maria Matilde; Correa-Medina, Mayrin; Whittington, Elizabeth E

Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith-Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with anteverted nose, bilateral bronchial stenosis due to lack of cartilage, bilateral obstructive renal dysplasia and NB with glomeruloid features. The infant had visceromegaly, but neither gigantism nor hemihypertrophy. Immunohistochemistry for PAX2 (Paired box gene-2) and WT-1 (Wilms Tumor 1) were strongly positive in the areas of NB. GLEPP-1 (Glomerular Epithelial Protein) did not stain the areas of NB with a glomeruloid appearance, but was positive in the renal glomeruli as expected. We found neither associated bronchial stenosis nor the histology of NB resembling giant glomeruli in any of the reported cases of NB.

Giant fibroadenoma (GFA) has been defined as fibroadenoma greater than 5 cm in it's the widest diameter and/or weighing more than 500 g. A benign lesion, its size also raises the possibility of malignancy requiring differentiation from a malignant breast disease. When unilateral GFA presents with a severe breast asymmetry, due to its size, it is not correctable by simple enucleation alone. Postoperative asymmetry from volume and ptosis disparity results, which needs to be addressed at the primary surgery. The inverted "T" technique, which is effective in volume reduction and ptosis correction in breast hypertrophy, can be applied in the treatment of unilateral GFA. This is a retrospective review of all GFA treated by inverted "T" method. A retrospective review was carried out on all patients with GFA treated by inverted "T" skin pattern method over a period of 20 years (January 1988 to December 2007). The procedures were carried out at the University of Nigeria Teaching Hospital and the National Orthopedic Hospital, Enugu. Information, which included patients' demographics, pre-operative assessment, operative findings and outcome of surgery were obtained from the case files of the patients. The degree of ptosis was recorded for each patient. Diagnosis of GFA was made after clinical evaluation and pre-operative tissue biopsy. Immediate results of treatment were based on the patients' satisfaction, visual assessment of symmetry of size of breasts, correction of ptosis and position of nipple areola complex (NAC). A total of 27 patients underwent inverted "T" technique for excision of GFA in their breasts. Their average age was 17.5 years (range 12-25 years) delay in presentation ranged from 2 months to 15 months. In 16 patients (59.2%), the left breast was involved in GFA whilst the tumor occurred on the right breast in 11 (40.7%). The tumor weighed on the average 1500 g (range 655-2200 g). Average diameter of the tumor was 15 cm (range 12-20 cm). All quadrants of the

1. Tidal volume, end-tidal CO2, and ventilatory frequency in Tupinambis nigropunctatus were measured in response to CO2 (1-4%) delivered to either the mouth or nares. Additionally, the sensitivity of the ventilatory response to nasal CO2 was evaluated at CO2 concentrations less than 1%. The ventilatory parameters were also measured in response to CO2 (1-4%) delivered to the nares after the olfactory peduncle was transected. 2. It was found that (0.4-4%) nasal CO2 depressed ventilatory frequency by 9% to 83% respectively, while tidal volume was not significantly altered. CO2 (1-4%) delivered to the mouth produced no apparent changes in any of the ventilatory parameters. Following transection of the olfactory peduncle, nasal CO2 was ineffective in producing any change in ventilatory frequency or depth. 3. These findings indicate that CO2-sensitive receptors are located in either the nasal or vomeronasal membranes of tegu lizards and that the olfactory peduncle must be intact for these receptors to affect ventilatory changes in response to elevated CO2 concentrations. The receptors are capable of mediating a ventilatory response to CO2 concentrations lower than those found in either expired air or in confined spaces such as occupied burrows. 4. The discrepancies in the ventilatory responses of lizards and snakes to inspired CO2 reported in past experiments may be partially explained by the presence of nasal or vomeronasal CO2-sensitive receptors.

Full Text Available Cervical cancer screening usually requires use of a speculum to provide a clear view of the cervix. The speculum is one potential barrier to screening due to fear of pain, discomfort and embarrassment. The aim of this paper is to present and demonstrate the feasibility of a tampon-sized inserter and the POCkeT Colposcope, a miniature pen sized-colposcope, for comfortable, speculum-free and potentially self-colposcopy.We explored different designs using 3D computer-aided design (CAD software and performed mechanical testing simulations on each. Designs were rapid prototyped and tested using a custom vaginal phantom across a range of vaginal pressures and uterine tilts to select an optimal design. Two final designs were tested with fifteen volunteers to assess cervix visualization, comfort and usability compared to the speculum and the optimal design, the curved-tip inserter, was selected for testing in volunteers.We present a vaginal inserter as an alternative to the standard speculum for use with the POCkeT Colposcope. The device has a slim tubular body with a funnel-like curved tip measuring approximately 2.5 cm in diameter. The inserter has a channel through which a 2 megapixel (MP mini camera with LED illumination fits to enable image capture. Mechanical finite element testing simulations with an applied pressure of 15 cm H2O indicated a high factor of safety (90.9 for the inserter. Testing of the device with a custom vaginal phantom, across a range of supine vaginal pressures and uterine tilts (retroverted, anteverted and sideverted, demonstrated image capture with a visual area comparable to the speculum for a normal/axial positioned uteri and significantly better than the speculum for anteverted and sideverted uteri (p<0.00001. Volunteer studies with self-insertion and physician-assisted cervix image capture showed adequate cervix visualization for 83% of patients. In addition, questionnaire responses from volunteers indicated a 92

Kaufman oculo-cerebro-facial syndrome (KOS) is caused by recessive UBE3B mutations and presents with microcephaly, ocular abnormalities, distinctive facial morphology, low cholesterol levels and intellectual disability. We describe a child with microcephaly, brachycephaly, hearing loss, ptosis, blepharophimosis, hypertelorism, cleft palate, multiple renal cysts, absent nails, small or absent terminal phalanges, absent speech and intellectual disability. Syndromes that were initially considered include DOORS syndrome, Coffin-Siris syndrome and Dubowitz syndrome. Clinical investigations coupled with karyotype analysis, array-comparative genomic hybridization, exome and Sanger sequencing were performed to characterize the condition in this child. Sanger sequencing was negative for the DOORS syndrome gene TBC1D24 but exome sequencing identified a homozygous deletion in UBE3B (NM_183415:c.3139_3141del, p.1047_1047del) located within the terminal portion of the HECT domain. This finding coupled with the presence of characteristic features such as brachycephaly, ptosis, blepharophimosis, hypertelorism, short palpebral fissures, cleft palate and developmental delay allowed us to make a diagnosis of KOS. In conclusion, our findings highlight the importance of considering KOS as a differential diagnosis for patients under evaluation for DOORS syndrome and expand the phenotype of KOS to include small or absent terminal phalanges, nails, and the presence of hallux varus and multicystic dysplastic kidneys.

During a lifetime, skin will change in appearance and structure not only because of chronological and intrinsic processes but also due to several external factors such as gravity, sun and ultraviolet exposure, and high levels of pollution; or lifestyle factors that have important and obvious effects on skin aging, such as diet, tobacco, illness, or stress. The effect of these external factors leads to progressive degradations of tegument that appear with different kinetics. The aim of this study was to clinically quantify the effect of sun exposure on facial aging in terms of the appearance of new specific signs or in terms of increasing the classical signs of aging. Materials and methods: This study was carried out on 298 Caucasian women from 30 years to 78 years old. The participants were divided into two groups according to their sun exposure history: 157 women were characterized as sun-seeking, and the other 141 were classified as sun-phobic. This division was made possible by dermatologist grading of heliodermal status on the basis of several observations of classic criteria: wrinkles, sagging, pigmentation heterogeneities, vascular disorders, elastosis, and so on. This work was an opportunity to complete clinical photographic tools by adding in our portfolio new scales for signs observed in the two groups. Thus, 22 clinical parameters were investigated by a panel of twelve trained experts to characterize each woman

Species-level analysis of DNA sequence data from the NIH Human Microbiome Project.

Outbreaks of antibiotic-resistant bacterial infections emphasize the importance of surveillance of potentially pathogenic bacteria. Genomic sequencing of clinical microbiological specimens expands our capacity to study cultivable, fastidious and uncultivable members of the bacterial community. Herein, we compared the primary data collected by the NIH's Human Microbiome Project (HMP) with published epidemiological surveillance data of Staphylococcus aureus. The HMP's initial dataset contained microbial survey data from five body regions (skin, nares, oral cavity, gut and vagina) of 242 healthy volunteers. A significant component of the HMP dataset was deep sequencing of the 16S ribosomal RNA gene, which contains variable regions enabling taxonomic classification. Since species-level identification is essential in clinical microbiology, we built a reference database and used phylogenetic placement followed by most recent common ancestor classification to look at the species distribution for Staphylococcus, Klebsiella and Enterococcus. We show that selecting the accurate region of the 16S rRNA gene to sequence is analogous to carefully selecting culture conditions to distinguish closely related bacterial species. Analysis of the HMP data showed that Staphylococcus aureus was present in the nares of 36% of healthy volunteers, consistent with culture-based epidemiological data. Klebsiella pneumoniae and Enterococcus faecalis were found less frequently, but across many habitats. This work demonstrates that large 16S rRNA survey studies can be used to support epidemiological goals in the context of an increasing awareness that microbes flourish and compete within a larger bacterial community. This study demonstrates how genomic techniques and information could be critically important to trace microbial evolution and implement hospital infection control.

To characterize the epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) transmission and infections in a level IIIC neonatal intensive care unit (NICU) and identify barriers to MRSA control. Retrospective cohort study in a university-affiliated NICU with an MRSA control program including weekly nares cultures of all neonates and admission nares cultures for neonates transferred from other hospitals or admitted from home. Medical records were reviewed to identify neonates with NICU-acquired MRSA colonization or infection between April 2007 and December 2011. Compliance with hand hygiene and an MRSA decolonization protocol were monitored. Relatedness of MRSA strains were assessed using pulsed-field gel electrophoresis (PFGE). Of 3,536 neonates, 74 (2.0%) had a culture grow MRSA, including 62 neonates with NICU-acquired MRSA. Nineteen of 74 neonates (26%) had an MRSA infection, including 8 who became infected before they were identified as MRSA colonized, and 11 of 66 colonized neonates (17%) developed a subsequent infection. Of the 37 neonates that underwent decolonization, 6 (16%) developed a subsequent infection, and 7 of 14 (50%) that remained in the NICU for 21 days or more became recolonized with MRSA. Using PFGE, there were 14 different strain types identified, with USA300 being the most common (31%). Current strategies to prevent infections-including active identification and decolonization of MRSA-colonized neonates-are inadequate because infants develop infections before being identified as colonized or after attempted decolonization. Future prevention efforts would benefit from improving detection of MRSA colonization, optimizing decolonization regimens, and identifying and interrupting reservoirs of transmission.

Full Text Available The emergence of severe acute respiratory syndrome (SARS in 2002 and 2003 affected global health and caused major economic disruption. Adequate animal models are required to study the underlying pathogenesis of SARS-associated coronavirus (SARS-CoV infection and to develop effective vaccines and therapeutics. We report the first findings of measurable clinical disease in nonhuman primates (NHPs infected with SARS-CoV.In order to characterize clinically relevant parameters of SARS-CoV infection in NHPs, we infected cynomolgus macaques with SARS-CoV in three groups: Group I was infected in the nares and bronchus, group II in the nares and conjunctiva, and group III intravenously. Nonhuman primates in groups I and II developed mild to moderate symptomatic illness. All NHPs demonstrated evidence of viral replication and developed neutralizing antibodies. Chest radiographs from several animals in groups I and II revealed unifocal or multifocal pneumonia that peaked between days 8 and 10 postinfection. Clinical laboratory tests were not significantly changed. Overall, inoculation by a mucosal route produced more prominent disease than did intravenous inoculation. Half of the group I animals were infected with a recombinant infectious clone SARS-CoV derived from the SARS-CoV Urbani strain. This infectious clone produced disease indistinguishable from wild-type Urbani strain.SARS-CoV infection of cynomolgus macaques did not reproduce the severe illness seen in the majority of adult human cases of SARS; however, our results suggest similarities to the milder syndrome of SARS-CoV infection characteristically seen in young children.

Impetigo is a bacterial infection of the superficial layer of the epidermis with crusting or bullae caused by Streptococcus spp., Staphylococcus spp., or both. A 14-yr-old red-tailed monkey ( Cercopithecus ascanius) presented with recurrent scabbing and ulceration under the nares over an 8-yr period. Repeated cultures and biopsy samples led to a presumptive diagnosis of impetigo, later confirmed on necropsy. Multiple antibiotic regimens were employed with varying success during multiple episodes, while lesions resolved on their own at other times. This condition has not been previously reported in a nonhuman primate, although it is not uncommon in humans.

Full Text Available During orthotopic ileocystoplasty, the short mesentery causes an increase in the risk of incompetence of anastomosis of the reservoir with the urethra. Inverting orthotopic ileocystoplasty ensures a free reservoir pull-through into the small pelvis and eliminates tissue tension in the anastomosis. The proposed procedure differs from the Studer operation in that the reservoir is sutured lengthwise, after which it is inverted between the mesenteric leaves. The posterior reservoir wall is anteverted and freely brought out into the small pelvis. This reduces the distance to the urethral stump by 3-4 cm. This procedure was used in 19 patients to be operated on. There were no cases of reservoir or reservoir-urethral anastomotic incompetence. The mean neocystic capacity was 110, 350, and 490 ml 0, 3, and 12 months, respectively, after urethral catheter removal. The maximum reservoir pressure does not exceed 40 (mean 30 cm H2O. Daytime urinary retention was 94.7%; nocturnal urinary retention during forced nocturnal miction was 79%. The obtained functional results compare well with those achieved during the similar procedures.

A 29-yr-old female western lowland gorilla (Gorilla gorilla gorilla) was evaluated for low fertility and a midterm abortion. Laboratory testing included karyotyping, which revealed an unusual mosaicism for Turner syndrome with Triple X (47,X/49,XXX). This appears to be the first report of Turner syndrome in a great ape. In humans, Turner syndrome occurs in approximately 1 in 3,000 females, with half of those monosomic for the X chromosome. A small proportion is mosaic for a triple X cell line (3-4%). In humans, Turner syndrome is associated with characteristic phenotype including short stature, obesity, a broad chest with widely spaced nipples, webbing of the neck, and anteverted ears. This individual gorilla is significantly shorter in stature than conspecifics and is obese despite normal caloric intake. Individuals with Turner syndrome should also be screened for common health issues, including congenital heart defects, obesity, kidney abnormalities, hypertension, hypothyroidism, and diabetes mellitus. Animals with decreased fertility, multiple miscarriages, fetal losses, unusual phenotypes, or a combination of these symptoms should be evaluated for genetic abnormalities.

Gynecomastia: the horizontal ellipse method for its correction.

Science.gov (United States)

Gheita, Alaa

2008-09-01

Gynecomastia is an extremely disturbing deformity affecting males, especially when it occurs in young subjects. Such subjects generally have no hormonal anomalies and thus either liposuction or surgical intervention, depending on the type and consistency of the breast, is required for treatment. If there is slight hypertrophy alone with no ptosis, then subcutaneous mastectomy is usually sufficient. However, when hypertrophy and/or ptosis are present, then corrective surgery on the skin and breast is mandatory to obtain a good cosmetic result. Most of the procedures suggested for reduction of the male breast are usually derived from reduction mammaplasty methods used for females. They have some disadvantages, mainly the multiple scars, which remain apparent in males, unusual shape, and the lack of symmetry with regard to the size of both breasts and/or the nipple position. The author presents a new, simple method that has proven superior to any previous method described so far. It consists of a horizontal excision ellipse of the breast's redundant skin and deep excess tissue and a superior pedicle flap carrying the areola-nipple complex to its new site on the chest wall. The method described yields excellent shape, symmetry, and minimal scars. A new method for treating gynecomastis is described in detail, its early and late operative results are shown, and its advantages are discussed.

The Co-Existence of Myasthenia Gravis in Patients with Myositis: A Case Series

Paik, Julie J.; Corse, Andrea M.; Mammen, Andrew L.

2014-01-01

Objective Myositis and myasthenia gravis (MG) are both autoimmune disorders presenting with muscle weakness. Rarely, they occur simultaneously in the same patient. Since the management of myasthenia gravis differs from that of myositis, it is important to recognize when patients have both diseases. We reviewed the cases of 6 patients with both myositis and MG to identify clinical features that suggest the possibility of co-existing MG in myositis patients. Methods We identified 6 patients with dermatomyositis or polymyositis and MG. We reviewed their medical records to assess their clinical presentations, laboratory findings, and electrophysiological features. Results All 6 patients had definite dermatomyositis or polymyositis by the criteria of Bohan and Peter as well as electrophysiologic and/or serologic confirmation of MG. Among overlap patients, 5/6 (83%) had bulbar weakness, 2/6 (33%) had ptosis, and 1/6 (17%) had diplopia. Fatigable weakness was noted by 5/6 (83%) patients. Treatment with pyridostigmine improved symptoms in 5/6 (83%). High dose steroids were associated with worsening weakness in 2/6 (33%) patients. Conclusions Prominent bulbar symptoms, ptosis, diplopia, and fatigable weakness should suggest the possibility of MG in patients with myositis. A suspicion of MG may be confirmed through appropriate electrophysiologic and laboratory testing. In those with myositis-MG overlap, high dose steroids may exacerbate symptoms and pryidostigmine may play an important therapeutic role. PMID:24412588

Myasthenia gravis is a rare acquired autoimmune pathology causing neuromuscular transmission impairment. Juvenile onset of myasthenia gravis is often characterized by ocular involvement. We report two cases of ocular juvenile myasthenia gravis (JMG) in two siblings. They were two young girls, XA and XB, aged 11 and 9 years, of Malian origin, residing in Togo, born from first-degree of consanguinity presenting to Ophthalmology due to progressive decrease in visual acuity. XA showed visual acuity 8/10 on both eyes while XB showed improvement in visual acuity from 3/10 to 7/10 using a pinhole occluder, suggesting ametropia. XA had a 2-year history of bilateral ptosis lifting the upper eyelid of 7 mm, while XB had a 3-year history of bilateral ptosis with no lifting of the upper eyelid. Ice pack test was strongly positive in both patients. They had Cogan's lid twitch with paresis of the oculomotor nerve without diplopia. The dosage of acetylcholine receptor autoantibodies was normal. The diagnosis of JMG associated with ametropia was suspected. Ametropia was corrected by glasses and a specific treatment with pyridostigmine was initiated, but both patients were lost to follow-up. Autoimmune myasthenia gravis with inaugural ophthalmologic manifestation is rare but it can occur among children living in sub-Saharan Africa. Studies should be conducted to establish the features of this disease.

Endoscopic sinus surgery (ESS) enjoys high success rates, but repopulation with pathogenic bacteria is 1 of the hallmarks of poorer outcomes. There are many hypothesized sources of repopulating bacteria; however, this process remains largely unexplored. This study examined changes in the sinus microbiome after ESS and medical therapies to identify potential sources for postsurgical microbial repopulation. Samples from the anterior nares, ethmoid sinus, and nasopharynx were taken at the time of surgery from 13 subjects undergoing ESS for chronic rhinosinusitis (CRS). Patients were treated postoperatively with 2 weeks of oral antibiotics and saline rinses. The ethmoid sinus was sampled at 2 and 6 weeks postoperatively; microbiota were characterized using quantitative polymerase chain reaction (qPCR) and 16S ribosomal RNA (rRNA) gene sequencing. The Morisita-Horn beta-diversity index (M-H) was used to compare similarity between samples. The bacterial burden of the ethmoid was higher 2 weeks postoperatively than 6 weeks postoperatively (p = 0.01). The 6-week samples most closely represented the anterior nares and ethmoid at surgery (M-H = 0.58 and 0.59, respectively), and were least similar to the nasopharynx (M-H = 0.28). Principal coordinates analysis (PCoA) plots illustrate that the ethmoid microbiota temporarily shifted after surgery and antibiotics but returned toward baseline in many subjects. Bacterial communities colonizing the ethmoid 6 weeks postoperatively were most similar to anterior nasal cavity and pretreatment sinus microbial profiles, indicating a high degree of resilience in the sinonasal microbiome of most subjects. Interestingly, surgery and postoperative antibiotic therapy does not appear to reduce bacterial burden, but rather, shifts the microbial consortia. © 2015 ARS-AAOA, LLC.

Species-level analysis of DNA sequence data from the NIH Human Microbiome Project.

Full Text Available BACKGROUND: Outbreaks of antibiotic-resistant bacterial infections emphasize the importance of surveillance of potentially pathogenic bacteria. Genomic sequencing of clinical microbiological specimens expands our capacity to study cultivable, fastidious and uncultivable members of the bacterial community. Herein, we compared the primary data collected by the NIH's Human Microbiome Project (HMP with published epidemiological surveillance data of Staphylococcus aureus. METHODS: The HMP's initial dataset contained microbial survey data from five body regions (skin, nares, oral cavity, gut and vagina of 242 healthy volunteers. A significant component of the HMP dataset was deep sequencing of the 16S ribosomal RNA gene, which contains variable regions enabling taxonomic classification. Since species-level identification is essential in clinical microbiology, we built a reference database and used phylogenetic placement followed by most recent common ancestor classification to look at the species distribution for Staphylococcus, Klebsiella and Enterococcus. MAIN RESULTS: We show that selecting the accurate region of the 16S rRNA gene to sequence is analogous to carefully selecting culture conditions to distinguish closely related bacterial species. Analysis of the HMP data showed that Staphylococcus aureus was present in the nares of 36% of healthy volunteers, consistent with culture-based epidemiological data. Klebsiella pneumoniae and Enterococcus faecalis were found less frequently, but across many habitats. CONCLUSIONS: This work demonstrates that large 16S rRNA survey studies can be used to support epidemiological goals in the context of an increasing awareness that microbes flourish and compete within a larger bacterial community. This study demonstrates how genomic techniques and information could be critically important to trace microbial evolution and implement hospital infection control.

Co-colonization and clonal diversity of methicillin-sensitive and methicillin-resistant Staphylococcus aureus in sows.

Methicillin-susceptible Staphylococcus (S.) aureus (MSSA) and methicillin-resistant S. aureus (MRSA) are colonizers of skin and mucosa. In humans, MSSA and MRSA compete for colonization space in the anterior nares of pig farmers; however, it was also shown that MSSA/MRSA co-colonization is common and one clone can be found rather than differing types of MSSA and MRSA. We investigated the colonization and clonality of both, MSSA and MRSA in pigs over a longer time. Eighteen sows were nasally sampled three times every ten weeks. Additionally, environmental samples were taken. Samples were investigated for MSSA and MRSA, respectively. The spa type was defined from up to five MRSA and MSSA isolates found per sample and sampling time; selected isolates were further investigated by microarray. Three sows (16.7%) were completely negative for MSSA and MRSA. Twelve pigs (66.7%) were irregularly positive for both, MSSA and MRSA over the time, whereas seven out of them (38.9%) were simultaneously colonized. CC398 (t034, t011) MRSA and CC9 (t337, t1430, and t13816) MSSA associated spa types were exclusively found. In 44.4% (n=8) of sows up to two different types of MSSA were present at the same time and sample. Strains of the same clonal lineage showed a high genetic identity despite their origin. Highly identic clones were present in sows and their environment. As conclusion, MSSA/MRSA may not exclude each other in the anterior nares of pigs. Pigs may also carry different clones at the same time. Copyright © 2016 Elsevier B.V. All rights reserved.

Innumerable approaches to the ptotic brow and forehead have been described in the past. Over the last twenty-five years, we have used all these techniques in cosmetic and reconstructive patients. We have used the endoscopic brow lift technique since 1995. While no one technique is applicable to all patients, the endoscopic brow lift, with appropriate modifications for individual patients, can be used effectively for most patients with brow ptosis. We present the nuances of this technique and show several different fixation methods we have found useful.

Wire-guided (Seldinger technique intubation through a face mask in urgent, difficult and grossly distorted airways

Directory of Open Access Journals (Sweden)

Jake M Heier

2012-01-01

Full Text Available We report two cases of successful urgent intubation using a Seldinger technique for airway management through an anesthesia facemask, while maintaining ventilation in patients with difficult airways and grossly distorted airway anatomy. In both cases, conventional airway management techniques were predicted to be difficult or impossible, and a high likelihood for a surgical airway was present. This technique was chosen as it allows tracheal tube placement through the nares during spontaneous ventilation with the airway stented open and oxygen delivery with either continuous positive airway pressure and/or pressure support ventilation. This unhurried technique may allow intubation when other techniques are unsuitable, while maintaining control of the airway.

The highlands of northeastern Honduras remain under-characterized in terms of biological diversity, as exemplified by the regularity of new amphibian and reptile taxa discoveries. Following the recent description of a new species of Nototriton from the Sierra de Agalta in northeastern Honduras, we report the discovery of a second new species of Nototriton from the nearby Parque Nacional Montaña de Botaderos. This new taxon, Nototriton mime sp. nov., is distinguished from other Nototriton by its distinctive pale brown dorsal coloration in adult males, relatively large nares, a relatively broad head, mitochondrial sequence divergence, and phylogenetic relationships, and is geographically isolated from other populations of Nototriton.

Full Text Available Background: It is challenging to manage congenital blepharoptosis, especially unilateral, because symmetry is difficult to achieve under general anesthesia and age at which the ptosis should be corrected is still controversial. The aim of our study is to analyze visual and surgical outcomes after levator resection for unilateral congenital blepharoptosis. Methods: Charts of patients with unilateral congenital blepharoptosis who underwent levator resection at the Chang Gung Memorial Hospital from 1991 through 2000 were reviewed. The resultant database was interrogated for demographic data, severity, surgical timing, visual outcomes, surgical outcomes, and complications. Results: Eighty-four children underwent levator resection for unilateral congenital blepharoptosis: 16.7% of these patients had amblyopia and 84.5% had surgical success following levator resection. Severe ptosis (p = 0.0288, p < 0.05 and surgery at less than 2 years of age (p = 0.0126, p < 0.05 were the important factors contributing to surgical failure. Age at surgery (p = 0.0058, p < 0.01 and amblyogenic ametropia (p = 0.0001, p < 0.001 were found to be significantly associated with the postoperative visual results. Conclusion: The levator resection provides satisfactory results both in function and cosmesis in patients with unilateral congenital blepharoptosis. Amblyogenic ametropia is the leading cause of amblyopia in the patients with unilateral isolated congenital blepharoptosis. However, patients with unilateral congenital blepharoptosis should have cycloplegic refraction as early as possible, and their visual status monitored until visual maturity.

Full Text Available The aim of this study was to examine levator palpebralis superior muscle histologically in patients with congenital blepharoptosis and to investigate the relationship between these findings and age, sex and degree of blefaroptosis in this patient group.Materials and methods: Levator muscle of 13 patients with congenital ptosis, who had applied to Dicle University Medical Faculty Ophthalmology Clinic and had undergone levator palpebralis superior muscle resection between january 2009-january 2010, has been examined histopathologically in Histology and Embriology Deparment. During preoperative period, ptosis amount, levator function (LF, tear functions, Bell’s phenomenon and jaw-winking phenomenon were evaluated. All patients underwent resection of levator palpebralis superior muscle. Received postoperative levator muscle was examined by light microscopy.Results: The average age of 9 (69.2% male and 4 (30.8% female cases were 10.61 ± 4.77 (4- 19 years. In histological examination, the quality and quantity of the levator muscle fibrils have been assessed. There was no relationship detected between histological features of levator palpebralis superior muscle and patient’s age and gender (p>0.05. Patients with weak levator palpebralis superior muscle were detected to have fatty degeneration histologically. The higher the levator palpebralis superior muscle function revealed decreased fatty degeneration and increased skeletal muscle fibrils.Conclusion: More ultrastructural studies in larger populations are needed to support the relationship between structure and function of levator palpebralis superior muscle in patients with congenital blepharoptosis.

Full Text Available Trans-orbital orbitocranial penetrating injury (TOPI by a foreign body is an extremely rare compound head injury having a potential to cause major morbidity and mortality. Preoperative radiological imaging by CT scan is very important for operative guidance, but in remote area where CT scan is not available, the patient is generally referred to tertiary level. Here we present a case which was dealt successfully without CT scan, only on the basis of stable clinical status and X-rays. We present a case of a 35-year-old man who had an accidental injury (fall from height by rod. Immediate X-ray (anteroposterior and lateral views revealed that the pointed end of the foreign body (rod was inside the ipsilateral anterior fossa via basifrontal bone up to frontal vertex, not crossing the midline. CT scan was not available and his vitals with GCS were normal (15/15. He was operated with the help of an ophthalmic surgeon by right frontotemporal craniotomy. The patient was discharged on 10 th day without any neurological deficit except restricted right eyeball movement to superolateral and ptosis. The restricted eyeball movements recovered after third month of follow up with remnant ptosis for 2 years. This case highlights an unusual case, direct visualization and repair of brain structures with higher antibiotics can save the life even in remote areas where CT scan is still not available only on the basis of stable GCS and X-rays.

Obesity is a worldwide problem that affects millions of people from a medical and psychological point of view. To solve the related complications, patients should lose weight with the consequent need to be subjected to body contouring due to the presence of a loose and redundant skin. We report our experience in the treatment of the post-bariatric breast. We considered all the post-bariatric patients subjected to a breast reshaping, and we viewed the features of the breast, the type of surgery performed, the outcomes, and the complications. All patients filled out BREAST-Q surveys both preoperatively and after 6 months to study the rate of satisfaction. Ninety post-bariatric patients underwent breast reshaping in the last 5 years. The average age was 40 years old. The follow-up period ranged from 6 months to 5 years. The most represented ptosis was second grade; the favorite technique has been mastopexy with parenchymal remodelling and augmentation with autologous tissue. The mean duration of the surgery has been 3 h. The most represented complications have been delayed healing, unfavorable scarring, hematoma, and seroma. Statistically significant improvements were observed in satisfaction with breast appearance, psychological, and physical well-being. Breast reshaping in post-bariatric patients is a big challenge and only a careful analysis of the degree of ptosis of the breast, its volume and shape, and a clear communication with the patients about the real outcomes and complications can make the winning surgeon.

Full Text Available Orbital apex syndrome (OAS is an uncommon disorder characterized by visual loss, ophthalmoplegia, ptosis and hypoaesthesia of the forehead[1]. OAS may result from a variety of inflammatory, infectious, neoplastic and vascular conditions that cause damage to the superior orbital fissure (with resultant oculomotor (III, trochlear (IV, abducens (VI and ophthalmic branch of the trigeminal nerve (V1 palsies and to the optic canal leading to optic nerve (II dysfunction. This case report describes the clinical development of OAS in a patient with bacterial sphenoid sinusitis.

Idiopathic orbital inflammation (IOI) is defined as a benign non-infective clinical syndrome characterized by features of non-specific inflammation of the orbit without identifiable local or systemic causes. This can be called orbital myositis if the inflammation is predominantly in the orbital muscles. It is a diagnosis of exclusion based on clinical, radiological, and if necessary, histological findings. The most commons symptoms are swelling, ptosis, proptosis and painful eye movements. To our knowledge, this patient is the first with IOI to demonstrate relapsing flitting bilateral involvement of several individual extra-ocular muscles. (orig.)

Extra-osseous uterine pathophysiology demonstrated on skeletal scintigraphy

International Nuclear Information System (INIS)

Mansberg, R.; Lewis, G.

1999-01-01

Full text: Skeletal scintigraphy is a sensitive procedure for evaluating disease and trauma involving the skeleton. Extra-skeletal pathophysiology is also often demonstrated. This may include uptake by tumours, soft tissue calcification and infection as well as renal pathology. Skeletal scintigraphy is often performed to evaluate hip and back pain and extra-osseous uterine pathophysiology can be demonstrated in both the early and late phases of the study as in the following cases. Three women underwent skeletal scintigraphy for the investigation of low back pain in two patients and post-partum hip pain in one. A large vascular uterus with deviation of the bladder was demonstrated in the post-partum patient. Increased pelvic vascularity and bladder deviation in the second patient was shown by ultrasound to correspond to a left-sided fibroid with associated adenomyosis. In the third case, right-sided pelvic vascularity and left bladder deviation were shown on ultrasound to be due to an anteverted, anteflexed uterus tilted to the right. These cases illustrate the importance of documenting extra-osseous findings on skeletal scintigraphy and the benefits of correlation with anatomical imaging

2003-08-01

D-2-hydroxyglutaric aciduria (D2HGA) is a rare autosomal recessive disorder with variable clinical expression. The biochemical defect is unknown at present. Previously reported cases have either followed a severe clinical course characterized by neonatal epileptic encephalopathy, cortical blindness, and profound developmental delay, or a mild course characterized by mild developmental delay, manageable epilepsy, and mild hypotonia. To date there has been a clear distinction between these two groups. We report the second case of a child with D2HGA who has followed an intermediate course. She presented in infancy with hypotonia, manageable epilepsy and developed moderate to severe developmental delay, and cortical visual impairment. The proposita had a coarse facial appearance, flat face, broad nasal bridge, up-turned nose, and simple, anteverted ears. These facial anomalies have been noted in other children with D2HGA and this case strengthens the proposed association between this facial phenotype and D2HGA. We also report the third and fourth instances of prenatal diagnosis for D2HGA. At each prenatal diagnosis, an affected fetus was diagnosed on the basis of markedly increased levels of D-2-hydroxyglutaric acid in amniotic fluid. Copyright 2003 Wiley-Liss, Inc.

Marker-assisted selection: Policy considerations and options for developing countries

International Nuclear Information System (INIS)

Dargie, J.D.

2007-01-01

Policy options for research, development and diffusion of the products of marker-assisted selection (MAS) depend on the development objectives and priorities of the agricultural sector, its various subsectors and cross-cutting activities dealing with science and technology (S and T), including biotechnology and the management of genetic resources. The policy agenda in each of these areas has shifted from the traditional focus of 'raising productivity' to a broader agenda of improving rural livelihoods in both economic and non-economic terms in support of the Millennium Development Goals (MDGs). Securing financial commitments from national governments and donors to invest in MAS and related molecular approaches requires more active engagement by national agricultural research and extension systems (NARES) in the processes of revising poverty reduction strategy papers (PRSPs), and in developing policies and strategies for agricultural development, S and T and genetic resources. Agriculture and agricultural S and T are undergoing rapid change but few developing countries have either agricultural S and T or biotechnology policies. They need to develop these to build coherence across the agricultural sector including delineating the roles of public and private sector entities, and as a means to strengthen accountability with respect to priority setting, monitoring and evaluating the outcomes and impacts of both research and practical applications of MAS. Options are provided for developing and implementing MAS programmes and projects, for setting priorities and evaluating outcomes and impacts. Given the uncertain nature of technical change and the long time frames that often characterize translation of the research and extension services provided by NARES into sustainable improvements in productivity and livelihoods through genetic enhancement, it is concluded that greater emphasis needs to be placed on research to analyse systematically the critical paths involved in

Nasal colonization of humans with methicillin-resistant Staphylococcus aureus (MRSA CC398 with and without exposure to pigs.

Directory of Open Access Journals (Sweden)

Christiane Cuny

Full Text Available BACKGROUND: Studies in several European countries and in North America revealed a frequent nasal colonization of livestock with MRSA CC398 and also in humans with direct professional exposure to colonized animals. The study presented here addresses the question of further transmission to non exposed humans. METHODS: After selecting 47 farms with colonized pigs in different regions of Germany we sampled the nares of 113 humans working daily with pigs and of their 116 non exposed family members. The same was performed in 18 veterinarians attending pig farms and in 44 of their non exposed family members. For investigating transmission beyond families we samples the nares of 462 pupils attending a secondary school in a high density pig farming area. MRSA were detected by direct culture on selective agar. The isolates were typed by means of spa-sequence typing and classification of SCCmec elements. For attribution of spa sequence types to clonal lineages as defined by multi locus sequence typing we used the BURP algorithm. Antibiotic susceptibility testing was performed by microbroth dilution assay. RESULTS: At the farms investigated 86% of humans exposed and only 4.3% of their family members were found to carry MRSA exhibiting spa-types corresponding to clonal complex CC398. Nasal colonization was also found in 45% of veterinarians caring for pig farms and in 9% of their non exposed family members. Multivariate analysis revealed that antibiotic usage prior to sampling beard no risk with respect to colonization. From 462 pupils only 3 were found colonized, all 3 were living on pig farms. CONCLUSION: These results indicate that so far the dissemination of MRSA CC398 to non exposed humans is infrequent and probably does not reach beyond familial communities.

Antigen Uptake during Different Life Stages of Zebrafish (Danio rerio Using a GFP-Tagged Yersinia ruckeri.

Rozalia Korbut

Full Text Available Immersion-vaccines (bacterins are routinely used for aquacultured rainbow trout to protect against Yersinia ruckeri (Yr. During immersion vaccination, rainbow trout take up and process the antigens, which induce protection. The zebrafish was used as a model organism to study uptake mechanisms and subsequent antigen transport in fish. A genetically modified Yr was developed to constitutively express green fluorescent protein (GFP and was used for bacterin production. Larval, juvenile and adult transparent zebrafish (tra:nac mutant received a bath in the bacterin for up to 30 minutes. Samples were taken after 1 min, 15 min, 30 min, 2 h, 12 h and 24 h. At each sampling point fish were used for live imaging of the uptake using a fluorescence stereomicroscope and for immunohistochemistry (IHC. In adult fish, the bacterin could be traced within 30 min in scale pockets, skin, oesophagus, intestine and fins. Within two hours post bath (pb Yr-antigens were visible in the spleen and at 24 h in liver and kidney. Bacteria were associated with the gills, but uptake at this location was limited. Antigens were rarely detected in the blood and never in the nares. In juvenile fish uptake of the bacterin was seen in the intestine 30 min pb and in the nares 2 hpb but never in scale pockets. Antigens were detected in the spleen 12 hpb. Zebrafish larvae exhibited major Yr uptake only in the mid-intestine enterocytes 24 hpb. The different life stages of zebrafish varied with regard to uptake locations, however the gut was consistently a major uptake site. Zebrafish and rainbow trout tend to have similar uptake mechanisms following immersion or bath vaccination, which points towards zebrafish as a suitable model organism for this aquacultured species.

2012-01-01

Between 8th July 2002 and 18th June 2004, aerosol samples were collected in Azores. Their inorganic composition was obtained by neutron activation analysis in order to study the differences of aerosols in two atmospheric altitudes of the central north Atlantic: (1) PICO-NARE observatory (Lower Free Troposphere-LFT) at Pico mountain summit (38,470 deg N, 28,404 deg W, 2,225 m a.s.l.) in Pico Island, Azores, where air masses from the surrounding continents (Africa, Europe, Central and North America) pass through, carrying aerosols with anthropogenic (Sb, Br, Mo, U, Se and Tb) and/or natural emissions (Fe, Co, La, Na, Sm, Cr, Zn, Hf, K and Th); (2) TERCEIRA-NARE station (Marine Boundary Layer) at Serreta (38,69 deg N, 27,36 deg W, 50 m a.s.l.), in Terceira Island, Azores, where natural aerosols (I, Cl, Na, Br and other soil related elements) are predominant. However, a combined interpretation of the data points out to a co-existence of the anthropogenic elements Sb and Mo, eventually with similar origins as the ones passing Pico Mountain summit. Very high concentrations and enrichment factors for Sb, Mo and Br in LFT, higher than the ones found in other areas, confirm atmospheric long-range transport mainly from the west boundary of north Atlantic; this may indicate eventual accumulation and persistence of those elements in the area due to the presence of Azores high pressures or the Hadley cells effect. A significant correlation between Fe and Yb and the enrichment of rare earth elements (La, Sm, Tb and Yb) and Th in LFT aerosols, both reflect a mineral dust intrusions from north Africa (Sahara and Sahel region).

The purpose of this study was to determine if a decolonization regimen reduces the frequency of methicillin-resistant Staphylococcus aureus (MRSA) infections and if colonization isolates are genetically related to subsequent infectious strains. Trauma patients admitted to the intensive care unit with positive MRSA nasal swabs were randomized to either daily chlorhexidine gluconate (CHG) baths and mupirocin (MUP) ointment to the nares or soap and water baths and placebo ointment for five days. Nasal swabs performed at the end of treatment and invasive MRSA infections during the remaining hospitalization were compared with the original nasal isolate via polymerase chain reaction for genetic relatedness as well as CHG and MUP resistance genes. Six hundred and seventy-eight intensive care unit admissions were screened, and 92 (13.6%) had positive (+) MRSA nasal swabs over a 22-month period ending in 3/2014. After the five day treatment period, there were 13 (59.1%) +MRSA second nasal swabs for CHG + MUP and 9 (90%) for soap and water baths and placebo, P = 0.114. No isolates tested positive for the MUP or CHG resistance genes mupA and qacA/B but 7 of 20 (35%) contained smr. There were seven (31.8%) MRSA infections in the CHG group and six (60%) for soap, P = 0.244. All 13 patients with MRSA infections had the same MRSA isolate present in the original nasal swab. There was no difference in all-cause Gram-negative or positive infections for CHG versus soap, 12 (54.5%) versus 7 (70%), P = 0.467. CHG + MUP are ineffective in eradicating MRSA from the anterior nares but may reduce the incidence of infection. Subsequent invasive MRSA infections are typically caused by the endogenous colonization strain.

Methicillin resistant Staphylococcus aureus (MRSA) is significant major pathogen responsible for hospital and community based infections. The aim of this study was to assess the nasal and hand carriage of methicillin resistant Staphylococcus aureus in health care workers of Mekelle Hospital The study was carried out during November 2010 to January 2011. Swab samples from both anterior nares and hands were taken. The samples were cultured on mannitol salt agar and incubated aerobically at 37 degrees C for 48 hours. Staphylococcus aureus was identified as nmannitol fermenter and coagulase test positive. Antimicrobial susceptibility test for MRSA was done by disk diffusion method using oxacillin disks. Data were analysed using SPSS version 16 software. Out of the 177 health care workers screened, 36 (20.3%) of them were methicillin resistant Staphylococcus aureus carriers in their hand and anterior nares. More females, 25(14.1%) were colonized by methicillin resistant Staphylococcus aureus than males 11 (6.2%) (P = 0.044). Nasal carriage of MRSA of 25 (14.1%) was higher than hand carriage 11 (6.2%) (p resistant Staphylococcus aureus carriage rates of 26 (13.6%) and 4 (2.3%), respectively. The isolated MRSA were resistant to multiple antibiotics. The highest resistance was observed for ampicillin (88.9%) and tetracycline (86.1%). Two (5.6%) of the nasal isolates were vancomycin resistant. Methicillin resistant Staphylococcus aureus carriage among health care workers in this study was high. The carriage rate was higher among nurses and doctors. The MRSA isolates were multi drug resistant to other antibiotics. So, the result of this study emphasizes the need of regular surveillance of health care workers. It also calls a need for an effective infection prevention and control program.

The Current State of Screening and Decolonization for the Prevention of Staphylococcus aureus Surgical Site Infection After Total Hip and Knee Arthroplasty.

Science.gov (United States)

Weiser, Mitchell C; Moucha, Calin S

2015-09-02

The most common pathogens in surgical site infections after total hip and knee arthroplasty are methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), and coagulase-negative staphylococci. Patients colonized with MSSA or MRSA have an increased risk for a staphylococcal infection at the site of a total hip or knee arthroplasty. Most colonized individuals who develop a staphylococcal infection at the site of a total hip or total knee arthroplasty have molecularly identical S. aureus isolates in their nares and wounds. Screening and nasal decolonization of S. aureus can potentially reduce the rates of staphylococcal surgical site infection after total hip and total knee arthroplasty.

Nipple-sparing mastectomy (NSM) is gaining popularity due to its superior aesthetic results. When reconstructing the breast with free abdominal tissue transfer, we must readdress the recipient vessel, because NSM can cause difficulty in access to the chest vessel. Between June 2006 and March 2011, a total of 92 women underwent NSM with free abdominal tissue transfer. A lateral oblique incision was used for the nipple-sparing mastectomy. For recipient vessels, the internal mammary vessels were chosen if the mastectomy flap did not block access to the vessels. If it did, the thoracodorsal vessels were used. Age, degree of breast ptosis, weight of the mastectomy specimen, and related complications of the internal mammary vessel group and the thoracodorsal vessel group were compared. Thoracodorsal vessels were used as recipient vessels in 59 cases, and internal mammary vessels in 33 cases including 4 cases with perforators of the internal mammary vessels. Breast reconstruction was successful in all cases except one case involving a total flap failure, which was replaced by a silicone gel implant. The internal mammary group and the thoracodorsal group were similar in terms of age, height, breast weight, and degree of ptosis. The flap related complications such as flap loss and take-back operation rates were not significantly different between the two groups. The rate of nipple necrosis was higher in the internal mammary group. The thoracodorsal vessels could produce comparable outcomes in breast reconstruction after nipple-sparing mastectomies. If access to internal mammary vessels is difficult, the thoracodorsal vessel can be a better choice.

2017-02-01

Intraneural arachnoid cyst is an extremely rare etiology of isolated cranial nerve palsy. Although seldom encountered in clinical practice, this pathology is amenable to surgical intervention. Correct identification and treatment of the cyst are required to prevent permanent nerve damage and potentially reverse the deficits. We describe a rare case of isolated third nerve palsy caused by an intraneural arachnoid cyst. A 49-year-old woman with a recent history of headaches experienced acute onset of painless left-sided third nerve palsy. According to hospital records ptosis, mydriasis, absence of adduction, elevation, and intorsion were noted in the left eye. Computed tomography and magnetic resonance imaging studies showed an extra-axial, 1-cm lesion along the left paraclinoid region, causing mild indentation on the uncus. There was dense fluid layering dependently concerning for hemorrhage, but no evidence of aneurysms. A pterional craniotomy was performed, revealing a completely intraneural arachnoid cyst in the third nerve. The cyst was successfully fenestrated. At 7-month follow-up, the left eye had recovered intact intorsion and some adduction, but the left pupil remained dilated and nonreactive. There was still no elevation and no afferent pupillary defect. Double vision persisted with partial improvement in the ptosis, opening up to more than 75% early in the day. To our knowledge, this is the first report of an intraneural arachnoid cyst causing isolated third nerve palsy. This rare pathology proves to be both a diagnostic and therapeutic challenge.

A case of Eaton-Lambert syndrome with small cell carcinoma of the lung responding favorably to chemotherapy and radiation was described. The patient, 56-year-old man, began to feel weakness of the upper limbs in 1982 (age 52). His condition deteriorated gradually, followed by weakness of the lower limbs, dysphagia and bilateral ptosis. He was admitted to our hospital in Janualy 1984. We started radiation therapy for the lung mass and his neurological findings improved slightly. In June 1984, he complained of pain in the left elbow accompanied by increased ptosis and weakness in the limbs. The biopsy of left elbow lymphnode revealed the metastasis of intermediate cell type small cell carcinoma of the lung, and the diagnosis of Eaton-Lambert syndrome was confirmed. Metastases were also found at the right parietal bone and cervical lymphnode. We started a combination chemotherapy consisting of ACNU, vincristine, methotrexate and cyclophosphamide, adding prophylactic irradiation to the cranium and metastatic regions. After treatment, the metastases disappeared completely and no abnormal findings were found except for decreased tendon reflexes of the upper limbs. Post-treatment electromyography showed marked reduction of waxing and post-tetanic facilitation. We have intermittently continued a combination chemotherapy for consolidation. The patient is living well 21 months after the distant metastases became apparent, and is showing marked improvement of Eaton-Lambert syndrome through chemotherapy and radiation. We propose that anti-neoplastic treatment is the first choice for the treatment of Eaton-Lambert syndorame associated with small cell carcinoma of long. (J.P.N.).

2017-02-01

Intraorbital meningoencephaloceles occur most commonly as a complication of traumatic orbital roof fractures. Nontraumatic congenital orbital meningoncephaloceles are very rare, with most secondary to destructive processes affecting the orbit and primary skull defects. Treatment for intraorbital meningoencephaloceles is surgical repair, involving the excision of herniated brain parenchyma and meninges and reconstruction of the osseous defect. Most congenital lesions present in infancy with obvious globe and orbital deformities; we report an orbital meningoencephalocele in a 3-year-old girl who presented with ptosis.

Full Text Available Blepharochalasis is a disorder characterized by recurrent episodes of painless edema of the eyelid skin, which leads to atrophy and relaxation of the eyelid structures and ptosis. The condition typically manifests itself in childhood or adolescence. The author reported a 16-year-old girl who has been suffered from recurrent painless swelling episodes on the upper eyelids for three years and laxity and wrinkling predominantly on the right upper eyelid for one year. This case was presented for the disorder is a rarely encountered disease and may easily misdiagnosed as recurrent angioedema, especially in its early stage.

To evaluate the efficacy of a novel mobile phone application that calculates superior visual field defects on Goldmann visual field charts. Experimental study in which the mobile phone application and 14 oculoplastic surgeons interpreted the superior visual field defect in 10 Goldmann charts. Percent error of the mobile phone application and the oculoplastic surgeons' estimates were calculated compared with computer software computation of the actual defects. Precision and time efficiency of the application were evaluated by processing the same Goldmann visual field chart 10 repeated times. The mobile phone application was associated with a mean percent error of 1.98% (95% confidence interval[CI], 0.87%-3.10%) in superior visual field defect calculation. The average mean percent error of the oculoplastic surgeons' visual estimates was 19.75% (95% CI, 14.39%-25.11%). Oculoplastic surgeons, on average, underestimated the defect in all 10 Goldmann charts. There was high interobserver variance among oculoplastic surgeons. The percent error of the 10 repeated measurements on a single chart was 0.93% (95% CI, 0.40%-1.46%). The average time to process 1 chart was 12.9 seconds (95% CI, 10.9-15.0 seconds). The mobile phone application was highly accurate, precise, and time-efficient in calculating the percent superior visual field defect using Goldmann charts. Oculoplastic surgeon visual interpretations were highly inaccurate, highly variable, and usually underestimated the field vision loss.

1985-12-01

The feasibility of safe ocean disposal options for heat-generating radioactive waste relies on the existence of suitable disposal sites. This review considers the status of the development of site selection criteria and the results of the study area investigations carried out under various national and international research programmes. In particular, the usefulness of the results obtained is related to the data needed for environmental and emplacement modelling. Preliminary investigations have identified fifteen potential deep ocean study areas in the North Atlantic. From these Great Meteor East (GME), Southern Nares Abyssal Plan (SNAP) and Kings Trough Flank (KTF) were selected for further investigation. The review includes appraisals of regional geology, geophysical studies, sedimentology, geotechnical studies, geochemical studies and oceanography. (author)

Postoperative infection of an abdominal mesh due to methicillin resistant Staphylococcus Aureus - A case report

2004-01-01

Full Text Available Methicillin resistant Stephylococcus aureus (MRSA infection has now become a major problem in hospitals. We present a case of postoperative infection MRSA where the primary source of the infection was found to be an abdominal mesh that was used to reinforce the abdominal wall. After one year of surgery, the patient developed wound dehiscence and discharge. MRSA was isolated from the wound, mesh, external nares, throat and axilla. Initially she was started on clindamycin and discharged from the hospital. After 5 months, patient came back to the hospital with infection at the same site. The patient was then treated with vancomycin and MRSA clearance. She responded to the treatment with complete healing of the wound and clearance of MRSA.

Sharma, B.G.

2003-01-01

A new type of rare bone dysplasia is described, which shares some common features with spondylo-meta-epiphyseal dysplasia: short limb-abnormal calcification type and lethal metatropic dysplasia. Besides these features, the present case has some additional unusual features. Facial malformation was very obvious and of a different type. The nose and nares were completely flattened. Hypertrophied acetabular bones, round densities on the ilia, premature ossification of many epiphyses and carpal bones, curvilinear calcifications in some joints, fusion of the ischiopubic rami, calcification of many costal cartilages and thick sclerotic base of the skull were a few of the significant findings. On the basis of the clinical and radiological features, the condition has been named ''spondylo-epi-metaphyseal dysplasia: mixed type''. (orig.)

Mutations in the mitochondrial DNA polymerase gamma (POLG) cause a highly pleomorphic disease spectrum, and reports about their frequencies in ataxia populations yield equivocal results. This leads to uncertainties about the role of POLG genetics in the workup of patients with unexplained ataxia. A comprehensive characterization of POLG-associated ataxia (POLG-A) will help guide genetic diagnostics and advance our understanding of the disease processes underlying POLG-A. Thirteen patients with POLG-A were assessed by standardized clinical investigation, nerve conduction studies, motor-evoked potentials, magnetic resonance imaging (MRI) and transcranial sonography (TCS). The findings were compared with 13 matched patients with Friedreich's ataxia (FA). In addition to the well-known POLG-associated features of chronic external ophthalmoplegia (100 %), areflexia to the lower extremity (100 %), impaired vibration sense (100 %), bilateral ptosis (69 %) and epilepsy (38 %), also hyperkinetic movement disorders were frequent in POLG-A patients, including chorea (31 %), dystonia (31 %) and myoclonus (23 %). Similar to FA, polyneuropathy was of sensory axonal type (100 %). In contrast to FA, none of the POLG-A patients showed impaired central motor conduction. TCS demonstrated less enlargement of the fourth ventricle and more diffuse cerebellar hyperechogenicity in POLG-A. Corresponding to TCS, MRI revealed no or only mild cerebellar atrophy in most POLG-A patients (85 %). POLG ataxia presents with the clinical characteristics of both afferent and cerebellar ataxia. Cerebellar alterations diffusely involve various parts of the cerebellum, yet cerebellar atrophy is generally mild. POLG-A presents with a high load of distinct non-ataxia features, namely, sensory neuropathy, external ophthalmoplegia, ptosis, epilepsy and/or hyperkinetic movement disorders. Involvement of the corticospinal tract, however, is rare.

A TRAM flap design refinement for use in delayed breast reconstruction.

LENUS (Irish Health Repository)

Patel, A J K

2009-09-01

Autologous breast reconstruction following mastectomy is commonly achieved using the free Transverse Rectus Abdominis Myocutaneous (TRAM) flap. Since its first description, refinements and modifications have resulted in improved operative techniques and more aesthetically pleasing reconstructions. Pre-operative flap design, however, is a relatively new concept that has not received much attention in the literature. Patients who undergo breast reconstruction may have large, ptotic contralateral breasts. In these patients there is a tendency to raise a large abdominal flap in an attempt to achieve symmetry, or simply a larger breast. This has the potential to lead to tight closure of the abdomen and the risk of subsequent wound problems. Reconstructions that are too small or have inadequate ptosis commit the patient to contralateral breast surgery to achieve symmetry. Pre-operatively designing the flap, using a template created from the opposite breast, can help achieve a good match, often reducing the need for contralateral breast surgery. Even when contralateral breast reduction surgery is planned in advance, many of these patients still require, and prefer, a large reconstruction in order to achieve a well-proportioned result. We present a design template that addresses these particular issues and in the senior author\\'s hands has proved to be a very effective technique. Our technique allows raising an abdominal flap of less vertical height than traditionally used (thus reducing the risk of tight abdominal closure) and incorporates an inverted V-shaped flap of skin from the inferior mastectomy skin flap into the reconstruction. This allows more flap tissue to be available to fill the upper poles of the reconstructed breast and at the same time produces good ptosis.

Paolo Pozzato

2013-04-01

Full Text Available BACKGROUND Von Hippel-Lindau disease (VHL is a rare autosomal dominant inherited disorder characterized by an increased risk of tumours in a number of locations (eyes, brain, adrenal gland, pancreas, liver, kidneys, or other areas of the body. It is caused by germline mutation in the VHL gene. The VHL gene is a tumour suppressor gene that has been identified on the short arm of chromosome 3. CASE REPORT We report a case of a 60 year-old female with the clinical diagnosis of VHL type 1 (cerebellar haemangioblastoma, pancreatic cysts with subsequent steatorrhoea, and bilateral renal carcinoma who developed weakness and fatigability of skeletal muscles, left lid ptosis, snarling expression and nasal timbre speech. Acetylcholine receptor antibodies were negative in serum, while the electrodiagnostic test demonstrated an alteration of neuromuscolar junction which was consistent with the diagnosis of myasthenia gravis. Contrast-enhanced TC scan of the anterior mediastinum was performed, which excluded thymus enlargement. VHL gene evaluation in this patient identified a new mutation (c279delC9 and polymorphism c291C>G. At present the patient still suffers from ataxia and dysmetria due to cerebellar involvement in VHL, while fatigue and lid ptosis improved after the treatment with oral pyridostigmine 60 mg tid. DISCUSSION AND CONCLUSIONS To our knowledge this is the first report of a case of VHL associated with myasthenia gravis without thymoma. A case of VHL associated with a form of myasthenia gravis related to thymoma has been recently reported. In our case the absence of acetylcholine receptor antibodies may suggest a genetic origin also for the myasthenia gravis.

Quality of life in purely ocular myasthenia in Japan

Science.gov (United States)

2014-01-01

Background Since there has been no conclusive evidence regarding the treatment of ocular myasthenia, treatment guidelines were recently issued by the European Federation of Neurological Societies/European Neurological Society (EFNS/ENS). However, the therapeutic outcomes concerning the quality-of-life (QOL) of patients with ocular myasthenia are not yet fully understood. Methods We investigated the therapeutic outcomes of patients with purely ocular myasthenia in a multicenter cross-sectional survey in Japan. To evaluate the severity of ocular symptoms, we used the ocular-quantitative MG (QMG) score advocated by Myasthenia Gravis Foundation of America. We used the Japanese translated version of the MG-QOL15, a self-appraised scoring system. Results Of 607 myasthenia gravis (MG) patients with an observation-duration of illness ≥ 2 years, the cases of 123 patients (20%) were limited to ocular muscles (purely ocular myasthenia). During the entire clinical course, 81 patients experienced both ptosis and diplopia, 36 had ptosis alone, and six had diplopia alone. Acetyl-cholinesterase inhibitors and prednisolone were used in 98 and 52 patients, respectively. Treatment improved ocular symptoms, with the mean reduction in ocular-QMG score of 2.3 ± 1.8 points. However, 47 patients (38%) failed to gain minimal manifestation or a better status. Patients with unfavorable outcomes also self-reported severe QOL impairment. Multivariate analyses showed that the pretreatment ocular-QMG score was associated with unfavorable outcomes, but not associated with the patient’s QOL. Conclusion A treatment strategy designed in accord with a patient's ocular presentation must be considered in order to improve ocular symptoms and the patient's QOL. PMID:24996227

Full Text Available Objective To compare the sensitivity and specificity of ice test, neostigmine test and single fiber electromyography (SFEMG in the diagnosis of ocular myasthenia gravis (OMG, so as to establish an appropriate process for the diagnosis of OMG. Methods A total of 116 patients with newly onset ptosis and/or diplopia were detected by ice test, neostigmine test and SFEMG. Patients were followed up for 6 months to observe the disease changes and experimental treatment effects. Results Apart from patients whose diagnosis was in doubt or lost to follow - up, and who were diagnosed as generalized myasthenia gravis (GMG, the definite diagnosis was finally made in 81 patients, including 21 OMG patients and 60 patients with ptosis and/or diplopia caused by other diseases. The sensitivity of ice test for diagnosis of OMG was 95.24% (20/21, and specificity was 98.33%(59/60. The sensitivity of neostigmine test for diagnosis of OMG was 90.48% (19/21, and specificity was 85% (51/60. The sensitivity of SFEMG for diagnosis of OMG was 95.24% (20/21, and specificity was 80% (48/60. Among 3 tests, only specificity was found significant difference (χ2 = 5.232, P = 0.022. The specificity of ice test was better than that of neostigmine test (χ2 = 5.707, P = 0.017 and SFEMG (χ2 = 6.023, P = 0.014. Conclusions The ice test achieved high sensitivity and specificity in the diagnosis of OMG. The combination of ice test, neostigmine test and SFEMG may have important clinical value for the early diagnosis of OMG. DOI: 10.3969/j.issn.1672-6731.2016.10.008

2012-01-01

Full Text Available We report a 54-year-old woman who suffered a commotio cerebri, whiplash injury and a chest trauma with sternal fracture due to a high-velocity car accident. Two months later, she developed unilateral ptosis and blurred vision, which worsened during the day. Multiple diagnoses were suggested, ranging from thoracic outlet syndrome towards depression. Symptoms persisted and five years later, the patient consulted a neurologist. Laboratory analysis revealed significantly elevated levels of antibodies to acetylcholine receptors, and the diagnosis of myasthenia gravis was made. Speculatively, the damage of retrosternal thymic remnants due to a sternal fracture might have precipitated the condition or exacerbated subclinical disease.

2007-01-01

We describe a patient who presented with excessive daytime sleepiness (EDS) and was eventually diagnosed with anti-Ma2 encephalitis. Neurological examination disclosed somnolence, left palpebral ptosis, and vertical gaze paresis. A brain MRI showed high signal intensity in the hypothalamus and each hippocampus. Ma2 antibodies were found in the patient's serum, and fiberbronchoscopy disclosed a lung carcinoma. After three months of steroid treatment, the results of the patient's neurological exam became normal. We conclude that anti-Ma2 encephalitis may present with mostly isolated EDS and that it may respond to steroids despite old age and the presence of an untreated lung cancer.

Full Text Available Two pairs of siblings with myasthenia gravis, belonging to two different families, are reported. This is the only record of familial myasthenia during the past twenty years, in a total of 145 patients seen at the Neurological Clinic of the São Paulo Medical School. In spite of the fact that myasthenia gravis does not show hereditary characteristics, the peculiar features of the four cases justify the present report. The two pairs of siblings were born from non myasthenic nor consanguineous parents. The disease started at birth showing bilateral partial eyelid ptosis in all patients. The course of the illness has been favorable. There was no thymoma.

We herein report the case of myasthenic crisis occurring in a 51-year-old man. He had experienced ptosis, increased body weight with edema, and fatigue with dyspnea. He presented at our emergency department with disturbed consciousness. He was originally diagnosed with myxedema coma, and he required artificial respiration. Because his weakness persisted and he was positive for anti-acetylcholine receptor antibodies and anti-muscle-specific tyrosine kinase antibodies, we diagnosed myasthenic crisis after various examinations. His clinical response to treatment was good and he was discharged in an ambulatory status 3 months after admission. This case demonstrates that myasthenic crisis may occur in association with myxedema.

The prevalence and spread of mupirocin and antiseptic resistance among colonizing and infectious Staphylococcus aureus were determined. S. aureus isolated from anterior nares and infection sites of patients hospitalized in the largest tertiary care referral hospital in Malaysia was investigated for mupirocin and antiseptic susceptibility testing, and for PCR detection of mupA, qacA/B, and smr genes. Twelve isolates showed resistance to mupirocin by disk diffusion, of which 10 (3.8%) harbored the mupA gene. Minimum inhibitory concentrations (MICs) ranged from 64 to 768 μg/ml for mupA positive and below 46 μg/ml for negative isolates. The mupA was more common among ST239 isolates (70%). The qacA/B was carried in 67 out of 95 methicillin-resistant Staphylococcus aureus (MRSA) (70.5%) and 3 out of 164 methicillin-susceptible Staphylococcus aureus (MSSA) (1.8%), while smr was carried in 6 out of 95 MRSA (6.3%) strains. MICs ranged from 3.9 to 15.6 μg/ml for benzethonium chloride (BTC) and benzalkonium chloride (BKC), and from 10.3 to 20.7 μg/ml for chlorhexidine digluconate (CHG). Isolates with qacA/B and smr or qacA/B alone showed higher MIC (20.7 μg/ml for CHG and 15.6 μg/ml for BTC and BKC) than the isolates that lacked antiseptic resistance genes (10.3 μg/ml for CHG and 3.9 μg/ml for BTC and BKC). In 16 cases, ST239 was isolated from the infection site and the nares simultaneously, and shared identical resistance patterns (qacAB or qacAB+smr), suggesting possible endogenous infection. Spread of low-level mupirocin resistance expressing ST239 MRSA and high-level resistance expressing emerging ST1, co-existing with antiseptic-resistant genes showing elevated MICs, should be monitored for effective infection control.

Feasibility of high level radioactive waste disposal in deep sea sediments

1987-01-01

For the past ten years, an international program has been conducted to investigate the concept feasibility for disposing of spent nuclear fuel waste in deep ocean sediments. These studies by the Seabed Working Group were coordinated by the Nuclear Energy Agency of the Organization for Economic Cooperation and Development. Penetrators have been considered as the primary method of waste emplacement. This required emphasis on studies of the nature of the plastic sediments which would form the primary barrier to the release of radionuclides into the biosphere. Site qualification guidelines, included criteria for tectonic and sedimentary stability over periods of at least 10 5 years. Using these guidelines two potential areas were identified: one in the Madeira Abyssal Plain; and one in the Southern Nares Abyssal Plain, both in the North Atlantic

Full Text Available Abstract Xanthomatous skin lesions and arthritis in children are not a common association. We present the case of a 3 year old girl who presented with xanthomatous lesions in the periungual region of both hands, around the nares and on her forehead, associated with significant arthritis that was clinically compatible with multicentric reticulohistiocytosis. However, pathology of the xanthomatous lesions was more suggestive of papular xanthoma, a disease that is not associated with arthritis. Based on her presentation and the negative lipid workup, she was treated for presumed multicentric reticulohistiocytosis. Multiple treatment strategies were utilized, with improvement on a combination of infliximab, methotrexate, and prednisone. We review the different diagnoses that should be considered in children with xanthomas and arthritis as well as the different pharmacologic therapies used in children with multicentric reticulohistiocytosis.

The integration of physiologically-targeted skin care in the management of atopic dermatitis: focus on the use of a cleanser and moisturizer system incorporating a ceramide precursor, filaggrin degradation products, and specific "skin-barrier-friendly" excipients.

Atopic dermatitis (AD) may be considered the "poster disease" for exemplifying the significance of abnormalities of the epidermal barrier that occur predominantly within the stratum corneum (SC) and upper epidermis. Specifically, impairments of the SC permeability barrier, antimicrobial barrier, and immunologic barrier contribute markedly to the fundamental pathophysiology of AD. The multiple clinical sequelae associated with epidermal barrier impairments inherent to AD include dry skin, pruritus, increased skin sensitivity to irritants and allergens, eczematous skin changes, staphylococcal skin and anterior nares colonization, and increase in some cutaneous infections (ie, molluscum contagiosum). This article addresses the pathophysiology of AD with clinically relevant correlations, and discusses the scientific basis of a specially designed cleanser and moisturizer system that incorporates ceramide technology and filaggrin degradation products along with other "barrier-friendly" excipients.

Primary Buttonhole Mastopexy and Nipple-Sparing Mastectomy: A Preliminary Report.

Salibian, Arthur H; Harness, Jay K; Mowlds, Donald S

2016-10-01

Patients undergoing nipple-sparing mastectomy and immediate-implant based reconstruction occasionally require a mastopexy based on their breast size and degree of ptosis. Previous reports have shown the feasibility of mastopexy-nipple-sparing mastectomy in selected patients to raise the nipple up to 5 cm. Major mastopexy with nipple transposition more than 6 cm in conjunction with nipple-sparing mastectomy for therapeutic indications has not been described. The authors review their experience with primary buttonhole mastopexy performed in conjunction with nipple-sparing mastectomy. Between 2008 and 2014, 16 patients (32 breasts) underwent bilateral primary mastopexy and nipple-sparing mastectomy with immediate staged implant-based reconstruction. The Passot buttonhole technique was used for the mastopexy in all patients, raising the nipple from 7 to 12 cm. Tumor-related data, risk factors, breast size, degree of ptosis, expander size, fill volume, selection criteria, and complications are discussed. The average follow-up period was 33 months (range, 14 to 80 months). There were no tumor recurrences, and all patients completed their reconstruction. Two patients required removal of the expander and delayed reconstruction because of infection and implant exposure due to nipple-areola loss. The reasons for nipple-areola loss and technical modifications to enhance skin viability by retaining a thin layer of subareolar breast tissue for removal during the second-stage implant exchange are discussed. Primary mastopexy using the buttonhole technique performed together with nipple-sparing mastectomy is a safe procedure with predictable results in patients with very large or ptotic breasts requiring lifts greater than 6 cm. The success of the combined procedure depends on preserving a thin layer of subareolar breast tissue and removing it at the time of implant exchange.

Full Text Available Extraocular myositis (EOM is not commonly encountered in dogs. It is generally diagnosed based on clinical features of exophthalmos without third eyelid protrusion, pain or vision loss. The traditional treatment of choice is prednisolone. This report describes a case of a mixed-breed puppy with clinical signs consistent with EOM, the use of ascorbic acid as an adjuvant to traditional corticosteroid therapy and rapid resolution of the condition without recurrence. It also shows that prolapse of the third eyelid and ptosis of the lower eyelids are possible signs of EOM during recovery. This is the first report of this sort from Africa and therefore the report is of epidemiological significance.

In this report, we present a 14-year-old girl, born to consanguineous parents, who presented with severe mental retardation, hypotonia, short stature, and congenital joint contractures. The craniofacial features were scaphocephaly, thin/long and immobile face, marked hypoplasia of the midface, temporal narrowness, blepharophimosis, palpebral ptosis, and strabismus. The combination of such a distinctive craniofacial appearance and psychomotor retardation allows us to recognize a new case of the Marden-Walker syndrome. Our patient represents one of the rare cases in which consanguineous mating supports the autosomal-recessive pattern of inheritance of this condition. Furthermore, through refining the phenotype of a surviving patient, this report may contribute to a better recognition of this disorder in older affected children.

2013-09-01

Full Text Available Introduction: Myotonic dystrophies are typically associated with ocular complications like ptosis, weakness of the ocular muscle and cataracts, but also with less recognized retinal changes. Case Report: A 41-year-old female with type 1 myotonic dystrophy complained of progressive vision loss. Slit lamp examination revealed the presence of typical bilateral polychromatic cataract with posterior subcapsular component. Dilated fundus examination was remarkable for bilateral macular depigmented changes. Multimodal imaging analysis of the macula suggested the presence of a butterfly-shaped pattern dystrophy. Discussion: In cases of myotonic dystrophies it is of great relevance to analyze the presence of retinal changes that might limit the visual improvement following cataract extraction.

Amblyopia is a unilateral or bilateral reduction of visual acuity secondary to abnormal visual experience during early childhood. It is one of the most common causes of vision loss and monocular blindness and is commonly associated with strabismus, anisometropia, and visual deprivation (in particular congenital cataract and ptosis). It is clinically defined as a two-line difference of best-corrected visual acuity between the eyes. The purpose of this study was to understand the neural mechanisms of amblyopia and summarize the current therapeutic strategies. In particular, the authors focused on the concept of brain plasticity and its implication for new treatment strategies for children and adults with amblyopia. Copyright 2014, SLACK Incorporated.

Wetlands are ecosystems with environmental and ecological importance that require of a new methodological and legal focus that allows developing conservation policies in agreement with the natural and socio-cultural conditions. In the Magdalena Medio Antioqueno, CORANTIOQUIA region, were recognized 362 wetlands, divided in two main groups; in Puerto Nare and Puerto Berrio to the south prevails herbaceous wetlands without permanent surface water, locally known as Bajos. In Yondo the wetlands have permanent surface water. The environmental dynamic depends from the geomorphologic and hydrological conditions and are affected in a differential way by the human action. The region is the result of a long occupation process that begins in prehistoric times and had changed depending on the different historical moments. This complex social configuration has given origin to diverse perceptions and types of appropriation of the wetlands what explains the identified environmental circumstances

Jejuno-jejunal intussusception in a guinea pig (Cavia porcellus

Full Text Available An approximately four-year-old male castrated guinea pig (Cavia porcellus was presented for painful defecation with a 24-hour history of hyporexia and intermittent episodes of rolling behavior. Upon presentation the patient was quiet, alert, and responsive, and mildly hypothermic. Abdominal palpation revealed an approximately 2-cm long oblong mass within the caudal abdomen. Abdominal radiographs revealed gastric dilation without volvulus and a peritoneal mass effect. The patient was euthanized following gastric reflux of brown malodorous fluid from his nares and oral cavity. A necropsy was performed and revealed a jejuno-jejunal intussusception causing mechanical gastrointestinal ileus, and gastric dilatation without volvulus. While non-obstructive gastrointestinal stasis is common and obstructive ileus is uncommon in guinea pigs, this report shows that intestinal intussusception is a differential in guinea pigs with ileus and gastric dilatation.

Anti-musk positive myasthenia gravis and three semiological cardinal signs

Full Text Available Myasthenia gravis (MG is a relatively uncommon disorder with an annual incidence of approximately 7 to 9 new cases per million. The prevalence is about 70 to 165 per million. The prevalence of the disease has been increasing over the past five decades. This is thought to be due to better recognition of the condition, aging of the population, and the longer life span of affected patients. MG causes weakness, predominantly in bulbar, facial, and extra-ocular muscles, often fluctuating over minutes to weeks, in the absence of wasting, sensory loss, or reflex changes. The picture of fluctuating, asymmetric external ophthalmoplegia with ptosis and weak eye closure is virtually diagnostic of myasthenia. We report an atypical MG case with three semiological cardinal signs.

Full Text Available A case of chronic sphenoidal sinusitis in a girl of 9 years old is proposed; in clinical picture oculomotor dysfunction occurred (ptosis, strabismus divergent, diplopia, epiphora. The condition was masked by neurological symptoms, and so initial differential diagnosis was between 1 ocular form of myopathy (including mitochondrial diseases, 2 ocular form of myasthenia and 3 onset of multiple sclerosis. The definite diagnosis «pansinusitis» was proposed by neurologist only after attentive analysis of clinical symptoms and data of MRI, only since 1,5 year after beginning of the disease. This clinical case demonstrates the complexity of differential diagnosis of chronic sphenoidal sinusitis in children and necessity of developed clinical thinking for a doctor of every speciality

We carried out the Irwin's test with some different extracts of the aerial parts of Thidax procumbens L., the leaves of Neurolaena lobata (L.) R. Br., bark and leaves of Byrsonima crassifolia (L.) Kunth. and Gliricidia sepium Jacq. Walp., and root and leaves of Petiveria alliacea L. At dosage of 1.25 g dried plant/kg weight aqueous extracts of bark and leaves of Byrsonima crassifolia (L.) Kunth. and Gliricidia sepium Jacq. Walp. demonstrated the most activity: decrease in motor activity, back tonus, reversible parpebral ptosis, catalepsy and strong hypothermia. These extracts of both plants were assayed for effects on CNS and they caused very significant reductions in spontaneous locomotor activity, exploratory behavior and rectal temperature and they increased the sodium pentobarbital-induced sleeping time.

Oculopharyngeal muscular dystrophy (OPMD) is a muscle-specific, late-onset degenerative disorder whereby muscles of the eyes (causing ptosis), throat (leading to dysphagia), and limbs (causing proximal limb weakness) are mostly affected. The disease is characterized by a mutation in the poly(A)-binding protein nuclear-1 (PABPN1) gene, resulting in a short GCG expansion in the polyalanine tract of PABPN1 protein. Accumulation of filamentous intranuclear inclusions in affected skeletal muscle cells constitutes the pathological hallmark of OPMD. This review highlights the current translational research advances in the treatment of OPMD. In vitro and in vivo disease models are described. Conventional and experimental therapeutic approaches are discussed with emphasis on novel molecular therapies including the use of intrabodies, gene therapy, and myoblast transfer therapy.

Impetigo is caused by both Streptococcus pyogenes and Staphylococcus aureus; the relative contributions of each have been reported to fluctuate with time and region. While S. aureus is reportedly on the increase in most industrialised settings, S. pyogenes is still thought to drive impetigo in endemic, tropical regions. However, few studies have utilised high quality microbiological culture methods to confirm this assumption. We report the prevalence and antimicrobial resistance of impetigo pathogens recovered in a randomised, controlled trial of impetigo treatment conducted in remote Indigenous communities of northern Australia. Each child had one or two sores, and the anterior nares, swabbed. All swabs were transported in skim milk tryptone glucose glycogen broth and frozen at -70°C, until plated on horse blood agar. S. aureus and S. pyogenes were confirmed with latex agglutination. From 508 children, we collected 872 swabs of sores and 504 swabs from the anterior nares prior to commencement of antibiotic therapy. S. pyogenes and S. aureus were identified together in 503/872 (58%) of sores; with an additional 207/872 (24%) sores having S. pyogenes and 81/872 (9%) S. aureus, in isolation. Skin sore swabs taken during episodes with a concurrent diagnosis of scabies were more likely to culture S. pyogenes (OR 2.2, 95% CI 1.1 - 4.4, p = 0.03). Eighteen percent of children had nasal carriage of skin pathogens. There was no association between the presence of S. aureus in the nose and skin. Methicillin-resistance was detected in 15% of children who cultured S. aureus from either a sore or their nose. There was no association found between the severity of impetigo and the detection of a skin pathogen. S. pyogenes remains the principal pathogen in tropical impetigo; the relatively high contribution of S. aureus as a co-pathogen has also been confirmed. Children with scabies were more likely to have S. pyogenes detected. While clearance of S. pyogenes is the key

Work on the permeability and consolidation characteristics of sediment cores from the north-east Atlantic has shown that each sediment type studied has a unique void ratio/permeability relationship and that the permeability decreases with effective stress more rapidly for fine than for coarser grained material. Significant over-consolidation is also present in Pacific red clays from the deep-sea drilling project. Their permeability is less for a given void ratio than that of their Atlantic counterparts. A theoretical analysis is given of the effects on permeability of deep open burrows revealed by improved core handling techniques. Mineralogy and sediment and water chemistry of six cores from the Nares Abyssal Plain have demonstrated the effects of lateral sediment redistribution and have shown only mildly reducing conditions. Pore water studies on a 4 m Kasten core from Great Meteor East show oxygen falling to zero within 30 cm of the sediment surface

The flux of organic carbon to the sediment was estimated using short-term moored sediment raps located 10 m and 95 m above the sediment surface. Sediment particles were obtained from these traps for gravimetric, elemental, and isotopic analyses. These analyses provide data about the total flux of material to the sediment and also the organic carbon and total nitrogen flux to the sediment. Two box cores were obtained which were used to provide: (1) pore water nutrient and dissolved free amino acid content; (2) down core profiles of organic carbon and nitrogen; (3) bacterial counts and growth rates; (4) down core meiofaunal biomass and sensitivities; (5) down core water content. Four primary productivity stations were made to determine the rate at which organic material is photosynthetically produced by phytoplankton in the waters surrounding the Nares Abyssal Plain study area. Zooplankton studies were also conducted during the cruise

All patients had used latanoprost for more than 1 year (range, 12 to 45 months; mean, 26.0 months and were prostaglandin F2α analogue treatment-naïve. Digital photographs of the subjects obtained before latanoprost therapy and at the last examination were compared retrospectively. Four signs of PAP (deepening of the upper eyelid sulcus (DUES, upper eyelid ptosis, flattening of the lower eyelid bags, and inferior scleral show and supplemental side effects around the eyelids (eyelash growth, poliosis, and eyelid pigmentation were judged to be negative or positive by three independent observers. If the observers unanimously rated a sign as positive, the result was defined as positive.Results: Twelve subjects (54.5% had no apparent signs. Three subjects were judged to have DUES (13.6%, and two subjects each were judged to have flattening of the lower eyelid bags and eyelid pigmentation (9.0%. The other signs were judged as positive in only one subject each, respectively (4.5%. A univariate logistic regression analysis showed no significant associations between any of the signs and age, sex, or the duration of therapy.Conclusion: Latanoprost induced DUES, upper eyelid ptosis, flattening of the lower eyelid bags, inferior scleral show, and supplemental side effects around the eyelids; however, the rates of such occurrence might be relatively low.

The purpose of this work was to identify parameters influencing the risk of late radiation side effects, fair or poor cosmetic outcomes (COs) and pain in breast cancer patients after breast-conserving therapy (BCT) and three-dimensional conformal radiotherapy (3D-CRT). Between 2006 and 2013, 159 patients were treated at the Hannover Medical School. Physician-rated toxicity according to the LENT-SOMA criteria, CO and pain were assessed by multivariate analysis. LENT-SOMA grade 1-4 toxicity was observed as follows: fibrosis 10.7 %, telangiectasia 1.2 %, arm oedema 8.8 % and breast oedema 5.0 %. In addition, 15.1 % of patients reported moderate or severe breast pain, and 21.4 % complained about moderate or severe pain in the arm or shoulder. In multivariate analysis, axillary clearing (AC) was significantly associated with lymphoedema of the arm [odds ratio (OR) 4.37, p = 0.011, 95 % confidence interval (CI) 1.4-13.58]. Breast oedema was also highly associated with AC (OR 10.59, p = 0.004, 95 % CI 2.1-53.36), a ptosis grade 2/3 or pseudoptosis and a bra size ≥ cup C (OR 5.34, p = 0.029, 95 % CI 1.2-24.12). A ptosis grade 2/3 or pseudoptosis and a bra size ≥ cup C were the parameters significantly associated with an unfavourable CO (OR 3.19, p = 0.019, 95 % CI 1.2-8.4). Concerning chronic breast pain, we found a trend related to the prescribed radiation dose including boost (OR 1.077, p = 0.060, 95 % CI 0.997-1.164). Chronic shoulder or arm pain was statistically significantly associated with lymphoedema of the arm (OR 3.9, p = 0.027, 95 % CI 1.17-13.5). Chronic arm and breast oedema were significantly influenced by the extent of surgery (AC). Ptotic and large breasts were significantly associated with unfavourable COs and chronic breast oedema. Late toxicities exclusive breast pain were not associated with radiotherapy parameters. (orig.) [de

Full Text Available The cavernous sinus (CS is a paired venous sinus that runs along either side of the pituitary gland on the floor of the calvarium. Cavernous sinus syndrome (CSS refers to deficits in more than one of the cranial nerves III, IV, V, and VI, as they are in close association in this region. The purpose of this study was to identify the presenting complaints, neurologic findings, diagnosis, and outcomes in dogs and cats with confirmed cavernous sinus syndrome (CSS. Medical records between 2002 and 2015 were reviewed. Inclusion criteria were neurologic signs consistent with CSS and advanced imaging and/or post-mortem examination. Thirteen dogs and 2 cats were included. Twelve dogs received advanced imaging. Post-mortem examination was performed on 2 cats and 3 dogs. Dogs were 6 -13 years (mean= 10.8 years of age and comprised of several different breeds. Both cats were male neutered domestic shorthair, ages 3 and 14 years. Presenting complaints included mydriasis (N=4, behavior changes (N=3, hyporexia (N=3, ptosis (N=2, ataxia (N=2, pain (N=2, weakness (N=2, lethargy (N=2, and one each of epiphora, ocular swelling, polydipsia, seizures, facial muscle atrophy, dysphagia, and head tilt. Neurologic signs included ophthalmoparesis/plegia (N=13, reduced/absent pupillary light response (N= 11, mydriasis (N= 10, reduced/absent corneal sensation (N= 7, ptosis (N= 6, reduced facial sensation (N= 2, and enophthalmos (N=1. Thirteen patients had a mass lesion within the cavernous sinus, 6 of which were confirmed neoplastic via histopathology. Median survival time for the 4 patients treated with radiation therapy was 1035 days (range 150-2280. Median survival for the 4 patients that received medical treatment was 360 days (range 7-1260 days, and for the 5 non-treated patients 14 days (range 0-90 days. In conclusion mydriasis and ophthalmoplegia are common signs of CSS. A mass lesion within the CS is the most common cause. Survival time may be improved with

Background Thyroid-associated orbitopathy is commonly associated with Graves' disease with lid retraction, exophthalmos, and periorbital swelling, but rarely with autoimmune thyroiditis or euthyroid state. We reviewed 3 cases from our hospital whose antibodies to anti-receptor of TSH were normal. Methods Case 1: 60 year-old non-diabetic woman with bilateral glaucoma in treatment, recurrent media otitis and euthyroidism, acute onset of painless diplopia, and lid ptosis in the left eye. MRI of orbit showed increased size of the III right cranial pair and high levels of thyroid autoantibodies (Tab) anti-tiroglobulin (ATG) 115.1, anti-thyroid peroxidase (ATPO) 1751 U/mL. She started oral deflazacort 30 mg each 3 days. Sixty days later, complete remission of eye symptoms correlated with lower auto-antibodies level (ATG 19 ATPO 117). Case 2: 10 year-old girl. At age 8, she had diplopia, lid ptosis and limitations of upper gaze in the left eye. The neurological study discarded ocular myasthenia; with thyroid goitier, and hypothyrodism, she started oral levothyroxin. At age 10 with normal IRM Botulinic toxin was injected, without change. High levels of Tab were found, ATG 2723, ATPO 10.7. She started oral deflazacort 30 mg each 3 days, azathioprin 100 mg, daily. Actually, Tab levels are almost normal, but she remains with ocular alterations. Case 3: 56 year-old woman, Grave´s disease with exophtalmos in 1990, treated with I131 and immunosupression, with good outcome; obesity, hypertension and bilateral glaucoma in treatment. She suddenly presented diplopia and IV pair paresia of the right eye. A year later, ATb were found slightly elevated, ATG 100 years ATPO 227; despite prednisone 50 mg, each 3 days and azathioprin 150 mg/daily treatment, a surgical procedure was required for relieve the ocular symptoms. Results We found only 3 cases previously reported with this type of eye thyroid disease. Is important to note that awareness of this atypical form of orbitopathy

Otitis media is a well-known condition and its infra-temporal and intracranial complications are extremely rare because of the widespread usage of antibiotic treatment. We report a case of 63-year-old female with complaints of right-sided facial pain and diplopia. She had a history of acute otitis media before 4 months of admission to our neurology unit. Neurological examination showed that total ophthalmoplegia with ptosis, mydriasis, decreased vision and loss of pupil reflex on the right side. In addition, there was involvement of 5th and 7th cranial nerves. Neurological and radiological follow-up examinations demonstrated Jacod's Syndrome with unusual facial nerve damage and infection in aetiology. Sinusitis is the most common aetiology, but there are a few cases reported Jacod's Syndrome originating from otitis media.

Blepharoptosis is a condition of inadequate upper eyelid position, with a downward displacement of the upper eyelid margin resulting in obstruction of the superior visual field. Levator resection is an effective technique that is routinely used to correct aponeurotic ptosis. The anterior levator resection is the procedure of choice in moderate blepharoptosis when there is moderate to good levator muscle function, furthermore, with an anterior approach, a greater resection can be achieved than by a conjunctival approach. The authors describe a modification in the Putterman technique with a resection done over a plicated elevator, plication that was suggested by Mustardè. The technique has been named as elevator muscle anterior resection. The elevator muscle anterior resection inspires from the Fasanella-Servat operation by the use of a clamp, making the operation simple and predictable.

Full Text Available We present a boy of eight years of age with symptoms of Kearns-Sayre syndrome (KSS characterised by ophthalmoparesis, palpebral ptosis, mitochondrial myopathy, pigmentous retinitis, associated to short stature, cerebellar signs, cardiac blockade, diabetes mellitus, elevated cerebrospinal fluid protein concentration, and focal hand and foot dystonia. The skeletal muscle biopsy demonstrated ragged red fibers, cytochrome C oxidase-negative and succinate dehydrogenase-positive fibers. The magnetic resonance imaging showed symmetrical signal alteration in tegmentum of brain stem, pallidum and thalamus. Mitochondrial DNA analysis from skeletal muscle showed a deletion in heteroplasmic condition. The association of dystonia to KSS, confirmed by molecular analysis, is first described in this case, and the importance of oxidative phosphorylation defects in the physiopathogenesis of this type of movement disorder is stressed.

The patient had a history of right upper lid ptosis for 25 years that was exacerbated over the previous month with severe incapacity to open her right eye. No other associated neurological or ophthalmic symptoms were observed. The patient was treated with botulinum toxin (BoNT-A injection into the pretarsal and lateral canthus region of the orbicularis oculi of the affected eyelid. Treatment with BoNT-A is an effective method of managing ALO in Becker MC. This is the first case of unilateral ALO in the course of Becker MC that was successfully treated with injections of botulinum toxin.

We report a 13-year-old female patient with multiple congenital abnormalities (microcephaly, facial dysmorphism, anteverted dysplastic ears and postaxial hexadactyly), mental retardation, and adipose-gigantism. Ultrasonography revealed no signs of a heart defect or renal abnormalities. She showed no speech development and suffered from a behavioural disorder. CNS abnormalities were excluded by cerebral MRI. Initial cytogenetic studies by Giemsa banding revealed an aberrant karyotype involving three chromosomes, t(2;4;11). By high resolution banding and multicolour fluoresence in-situ hybridisation (M-FISH, MCB), chromosome 1 was also found to be involved in the complex chromosomal aberrations, confirming the karyotype 46,XX,t(2;11;4).ish t(1;4;2;11)(q43;q21.1;p12-p13.1;p14.1). To the best of our knowledge no patient has been previously described with such a complex translocation involving 4 chromosomes. This case demonstrates that conventional chromosome banding techniques such as Giemsa banding are not always sufficient to characterise complex chromosomal abnormalities. Only by the additional utilisation of molecular cytogenetic techniques could the complexity of the present chromosomal rearrangements and the origin of the involved chromosomal material be detected. Further molecular genetic studies will be performed to clarify the chromosomal breakpoints potentially responsible for the observed clinical symptoms. This report demonstrates that multicolour-fluorescence in-situ hybridisation studies should be performed in patients with congenital abnormalities and suspected aberrant karyotypes in addition to conventional Giemsa banding.

Tantalum (Ta) oxides and their coatings have been proved to increase their applications in the biomedical fields by improving osseointegration and wear resistance. In this study, Ta oxide coatings containing different proportions of Ag are deposited on SS304 materials. A twin-gun magnetron sputtering system is used to deposit the tantalum oxide-Ag coating. In this study, Staphylococcus aureus, which exhibits physiological commensalism on the human skin, nares, and mucosal and oral areas, is chosen as the model for in vitro antibacterial analyses via a fluorescence staining method using Syto9. The cytocompatibility and adhesive morphology of human skin fibroblast cells (CCD-966SK) on the coatings are also determined by using the microculture tetrazolium assay. This study shows that Ta 2 O 5 and Ta 2 O 5 -Ag coatings with 12.5 at. % of Ag exhibit improved antibacterial effects against S. aureus and have good skin fibroblast cell cellular biocompatibility

Transmission of Staphylococcus aureus colonization in community-based populations is not well understood. We sought to describe the molecular epidemiology of S. aureus colonization in the Old Order Amish. The study was a prospective, observational study of healthy adults and their same-sex siblings who were cultured from the anterior nares twice. S. aureus isolates were characterized using spa typing. Overall, 40% (159/398) of the study population was colonized with S. aureus. There were 84 spa types with the most abundant spa types being t012 (13%) and t021 (7%). There was no clustering of spa types within sibling groups; however, there was clustering within households. There were 111 S. aureus-colonized participant pairs living within the same household. Of these, 47% had concordant spa types. The diversity of spa types across a relatively isolated, genetically homogenous population with a similar lifestyle is striking. Taken together this suggests that S. aureus transmission is a local phenomenon limited to very close contact.

To describe a technique for reconstruction of the rostral aspect of the muzzle of a dog after traumatic amputation. Clinical report. Adult female dog. A 6-year-old, intact, female, mixed-breed dog was admitted for facial reconstructive surgery after traumatic amputation of the rostral aspect of the muzzle. The nasal planum and the rostral portion of the upper lips were missing. A hard palate mucoperiosteal flap and lateral labial advancement flaps were used to reconstruct the nasal philtrum and borders of the nares. This reconstructive technique resulted in adequate nostril function and an acceptable cosmetic outcome. One naris developed partial obstruction with granulation tissue that may have occurred because of a lack of circumferential nasal mucosa to appose the skin on that side. The mucoperiosteum of the hard palate can be used to reconstruct the rostral aspect of the muzzle after traumatic amputation, resulting in an acceptable cosmetic outcome. © Copyright 2012 by The American College of Veterinary Surgeons.

Little data is available on the epidemiology of Staphylococcus aureus in Africa. In the present study we aim at characterizing the population structure of S. aureus in healthy subjects from a rural and a semi-urban area in Lambaréné, Gabon as well as in hospital staff and inpatients. In total, 500 subjects were screened for S. aureus colonization of the nares, axillae and inguinal region. Overall, 146 (29%) were positive. We found 46 different spa types. The most frequent spa types were t084 (35%) and the agr II was the most prevalent subtype of the accessory gene regulator (56%, n=82). Five isolates (3%) were methicillin resistant S. aureus (MRSA). Carriage rates of S. aureus in Gabon are comparable to developed countries. MRSA is for the first time described and could pose a significant health threat in this region with limited access to microbiological laboratory facilities and to adequate antimicrobial agents.

Methicillin-resistant Staphylococcus aureus (MRSA) infections are associated with increased mortality, costs and length of stay compared to non-MRSA infections. This observational 4-year study analyses the impact of screening and treating orthopaedic healthcare workers for MRSA colonisation. A total of 1,011 swabs were taken from 566 healthcare workers. Positive healthcare workers were treated with topical mupirocin to both anterior nares. The prevalence of MRSA colonisation on initial testing was 4.77%. The rate of positive MRSA colonisation of those tested on more than one occasion fell from 5.88% to 2.71% (p = 0.055) on subsequent screening. All healthcare workers receiving treatment were successfully cleared of colonisation; however, some required more than one course of treatment. These results show that there could be a role for screening and treating orthopaedic staff for MRSA colonisation as part of a strategy to reduce the prevalence of MRSA infections in orthopaedic units.

This report summarises the results of preliminary geochemical investigations at three North Atlantic study areas. The two eastern sites, on the Cape Verde abyssal plain (CV2) and east of Great Meteor Seamount (GME) were visited during 1982. The results presented are preliminary. Studies in the western Atlantic, close to the Nares Abyssal Plain study site are more detailed and are presented in a separate paper. The report shows for the first time the relative redox status of the three sites. The differences are unexpectedly large, the most reduced cores being recovered at GME and the most oxidised at CV2. The sporadic nature of Recent sediment accumulation at these sites is also emphasised. In order to place these preliminary results in context their relevance to the production of mathematical system models is discussed in a closing section. The necessity for such models to rest on sound foundations of geochemical understanding is noted. Suggestions on future research priorities are offered for discussion. (author)

“Glava že vsěm Biblïja”. Le citazioni bibliche nell’opera di H.S. Skovoroda (1722-1794 tra tradizione slava ecclesiastica e cultura barocca

Full Text Available Innumerable quotations from the Bible permeate all Skovoroda’s writings, and yet no systematic analysis of the philosopher’s biblical quotations (or of his quotations from other ecclesiastical sources has ever been made . In this article I isolate all the biblical quotations incorporated in the dialogue Beseda 1-ja narečennaja Observatorium (Sion, while pointing to their role as a crucial component of the spiritual meaning of the text. It is my contention that Skovoroda’s use of the Bible follows the rhetorical and theological patterns already outlined by R. Picchio in his seminal works on the function of “biblical thematic clues”. On the other hand, the often whimsical distribution of biblical quotations and their complicated linking with one another are to be placed in the Baroque tradition, where, as P. Lewin’s studies on Ukrainian scholastic drama have successfully demonstrated, quotations from the Bible fulfilled stylistic as well as theological functions.

Mastopexia tridimensional con anclaje efectivo: Una respuesta a la ptosis, alteraciones de volumen, flacidez y recidiva en las mamoplastias 3D Mastopexy with a dependable anchoring site: A logical response to ptosis, volume alterations, flaccidity and relapse in mammaplasties

Full Text Available La mastopexia es la técnica quirúrgica común que la Cirugía Plástica realiza en las mamas. En la literatura, se han expuesto múltiples y muy buenas técnicas sin terminar la búsqueda del elemento que sea consistente y que provea la mayor permanencia de resultados. De manera habitual, la atención se ha enfocado hacia la modificación anatómica del polo inferior, tratando de rellenar el polo superior de la mama de manera indirecta, con la confusión generalmente establecida de que, en la mayoría de las técnicas descritas, se considera el sostenimiento como sinónimo de suspensión. De manera descriptiva, exponemos una alternativa de suspensión que resulta tan interesante como sencilla, produciendo los resultados esperados a largo plazo y simplificando la técnica al reducir de manera importante la falta de mantenimiento del relleno del polo superior de la mama, el tiempo operatorio y facilitar la reconstrucción del molde mamario. La detección de un punto anatómico de fusión entre la fascia superficial, que es una continuación de la glándula mamaria y la propia fascia pectoral en la pared torácica, de importancia quirúrgica para el anclaje de la glándula mamaria, y el desarrollo de una técnica simple de suspensión glandular, logran cambiar los conceptos acostumbrados de nuestra práctica. La remodelación de la glándula se vuelve más sencilla y se autonomiza el manejo de la cubierta cutánea, permitiendo reducir la longitud final de las cicatrices.The elusive long term result in mastopexy, reveals the lack of an element that provides with certainty, an alternative that maintains the result surgically obtained. Although myriads of alternatives have been proposed in modern literature, most of them referred to lower pole anatomical molding as an indirect way to modify the upper pole as well, which is in fact the main target expectation for a good and sustained surgically outcome. There is a factor of confusion that has not been currently clarified; sustenance is not necessarily a synonym of suspension, being the latter our main objective that induced to present this technical proposal. The anatomical site of fusion of the superficial fascia which is in continuity with the mammary gland, and the proper pectoralis fascia, means that this structure can be used as a reinforced tissue that becomes as an anchoring site for the breast gland. An easily placement transglandular sutures stablishes the expected real suspension and the technical benefits derived from it, with the advantage of the use of non absorbable suture material that provides the occasion of change for a better good.

Four flavanones (pinostrobin, pinocembrin, sakuranetin and naringenin), one dihydroflavonol (7-methyl aromadendrin) and one flavone (hispidulin) have been isolated from Artemisia campestris L. ssp. glutinosa Gay and identified by spectroscopic methods. Artemisia campestris L. sous-espèce glutinosa Gay est une Composée Anthémidée largement répandue sur les sables du littoral méditerranéean et abondante dans certaines régions d'Espagne et d'Italie. Dans le cadre d'une étude chimiotaxonomique du genre Artemisia Tourn., nous nous sommes intéressés à l'analyse des flavonoïdes, composés jamais décrits, à notre connaissance, dans cette espèce d' Artemisia. Les sommités fleuries d' Artemisia campestris sous-espèce glutinosa, séchées et pulvérisées, sont dégraissées à l'ether de pétrole et épuisées par le chloroforme. Le fractionnement de l'extrait chloroformique, par chromatographie sur colonne de silice, et la purification de certaines fractions conduisent à l'isolement de six génines flavoniques, à l'etat pur. L' étude des spectres UV, des spectres de masse et des spectres de RMN [1,2] et la comparaison avec des échantillons authentiques permettent de proposer, pour ces flavonoïdes, les structures de la pinostrobine [3], de la pinocembrine [4], de la sakuranétine, de la naringénine [5] (flavanones), de la méthyl-7-aromadendrine, [6, 7] (dihydroflavonol) et de l'hispiduline [8, 9] (flavone); quatre de ces génines sont méthylées. Parmi ces flavonoïdes, la pinostrobine n'a jamais été décrite, à notre connaissance, dans la famille des Composées; la pinocembrine, la sakuranétine et la naringénine ont déjà été signalées chez quelques Astéracées et Eupatoriées [10], et l'hispiduline dans la tribu des Anthémidées ( Santolina chamaecyparissus L.)

Two cases of cavernous sinus thrombophlebitis (CST) caused by dental infection are described. A 64-year-old woman presented with palsies of the left oculomotor and trochlear nerves after tooth extraction for dental caries in the left maxilla. A 54-year-old man presented with palsy of the left trochlear nerve, sensory disturbance in the ophthalmic and maxillary divisions of the left trigeminal nerve, ptosis, proptosis, and chemosis after dental treatment for caries and periodontitis in the left maxilla. In both patients, computed tomography and magnetic resonance imaging with contrast medium showed non-enhanced lesions within the left cavernous sinus and dilation of the superior ophthalmic veins, which indicated CST. These conditions were resolved by administration of broad-spectrum antibiotics. CST is rare but lethal, so prompt diagnosis is crucial, and immediate appropriate treatment is essential.

Botulism type E intoxication is a rare condition among human botulism. We aim to describe a first case of botulism type E intoxication in Taiwan. We report a 36-year-old young man with foodborne botulism type E associated with commercially vacuum packaged dried bean curd. He developed bilateral ptosis, diplopia and dysphagia 4 days after taking the dried bean curd. Electrophysiologic findings demonstrated waxing responses to 3 Hz repetitive nerve stimulation and decreased compound muscle action potentials on peripheral nerve conduction study. A bioassay for botulism in mice demonstrated that the patient had botulism caused by type E botulinum toxin. Antibodeis to C. botulinum type E were identified from his serum, confirming the diagnosis. This is the first known case of foodborne type E botulism in Taiwan. The potential source of this foodborne botulism should consider contaminated food made of soy beans.

{sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) is a widely used imaging modality in the initial diagnosis of cancer, treatment response evaluation and detection of recurrence. Herein, we present the case of a 39-year-old female who presented right ptosis on the follow-up of breast cancer after surgery. Clinicians suspected Horner's syndrome, and the patient underwent FDG PET/CT for the evaluation of recurrence that could cause Horner's syndrome. FDG PET/CT demonstrated a focal hypermetabolic lesion in the right cervicothoracic junction area, corresponding to the preganglionic cervical sympathetic trunk. A subsequent needle biopsy was done, and the lesion was confirmed as metastatic ductal carcinoma. In this case, we could detect the exact location of the recurring lesion that caused Horner's syndrome using FDG PET/CT.

In cluster headache there is often a considerable diagnostic delay - an average of 7 years in a population-based survey. Cluster headache is characterized by very severe...... or severe orbital or periorbital pain with a duration of 15-180 minutes. The cluster headache attacks are accompanied by characteristic associated unilateral symptoms such as tearing, nasal congestion and/or rhinorrhoea, eyelid oedema, miosis and/or ptosis. In addition, there is a sense of restlessness...... and agitation. Patients may have up to eight attacks per day. Episodic cluster headache (ECH) occurs in clusters of weeks to months duration, whereas chronic cluster headache (CCH) attacks occur for more than 1 year without remissions. Management of cluster headache is divided into acute attack treatment...

Facial nerve ganglioneuroblastoma in a feline leukemia virus-positive cat

Directory of Open Access Journals (Sweden)

Paula Reis Pereira

Full Text Available ABSTRACT: Neuroblastic tumors can originate from the central neuraxis, olfactory epithelium, adrenal medullary region or autonomous system. Ganglioneuroblastoma are a type of neuroblastic tumor, with very few case descriptions in animals. Diagnosis of facial nerve ganglioneuroblastoma was made in a feline leukemia virus-positive 11-month-old cat. The cat had hyporexia, left head tilt, depressed mental state, horizontal nystagmus, inability to retract the pinched left lip, anisocoria, ptosis, and absence of the menace reflex. Gross necropsy showed a mass at the left facial nerve root region. Histological examination of this mass showed neoplastic proliferation of neuroblasts arranged in a cohesive pattern and mature ganglion cells. Ganglion cells were positive for neurofilament, neuron-specific enolase, S100, and glial fibrillary acidic protein by immunohistochemistry, while neuroblasts were positive for vimentin, S100, neuron-specific enolase and feline leukemia virus.

Full Text Available Kearns-Sayre syndrome (KSS is a rare neuromuscular disorder. We report a case of a 14-year-old boy diagnosed and treated as myasthenia gravis for (4 years who was eventually diagnosed with KSS. He reported to us 3 years after initial presentation of mild drooping of eyelids with increased severity of ptosis, bilateral external ophthalmoplegia, and atypical retinitis pigmentosa. On multispecialty consultation, he was found to have right bundle branch block, wasting and weakness of limb muscles, and hearing loss. Sartorius muscle biopsy revealed ragged red fibres on trichrome stain. All these findings confirmed the diagnosis of Kearns-Sayre Syndrome (KSS. The take home message is to have a high index of suspicion for KSS when encountering cases of musculoskeletal disorders in subjects below 20 years of age in view of high morbidity and mortality associated with this syndrome.

Intraoral local anesthetics are widely used for performing painless dental treatments; however, in some cases, they may cause ocular complications such as meiosis, diplopia, nystagmus, ophthalmoplegia, ptosis, and amaurosis. Mostly, the symptoms disappear after several hours; rarely, they have a prolonged character. We describe the case of a 38-year-old young man who had reduced vision in the left eye 5 days after having received intraoral local anesthesia. A diagnosis of cilioretinal artery occlusion with optic disc swelling was made. Ten weeks later, the patient's visual acuity had increased to 20/20, and the swelling of the optic disc had subsided. Although various possible mechanisms for ocular complications after intraoral local anesthetic administration were suggested in the literature, the exact etiology remains unclear. In this case, inadvertent intravascular injection is believed to be the cause. PMID:29681838

evaluated with the Q test and I² index. Egger's significance test was used to identify the publication bias. Sensitivity analysis was performed to evaluate the effect of the publication biases. RESULTS: Eight randomized trials and thirteen case reports filled the inclusion criteria. In the systematic review of case reports, 1,003 subjects were studied and 182 (18.14% showed adverse effects. Eyelid ptosis was the most frequent adverse effect, presenting in 34 (3.39% patients of the case reports. In the meta-analysis of randomized trials, the overall relative risk for adverse effects as headache, eyelid ptosis, local reaction and infection was respectively: 1.07, 3.25, 0.99 and 0.94. For all comparisons, P values were greater than 0.05. CONCLUSION: Ptosis was the most frequent adverse effect and showed the higher relative risk associated with botulinum toxin. It is necessary to perform a pattern of adverse effects related for better understanding the relationship between adverse effects and use of botulinum toxin.

Dopamine-independent locomotor actions of amphetamines in a novel acute mouse model of Parkinson disease.

Directory of Open Access Journals (Sweden)

2005-08-01

Full Text Available Brain dopamine is critically involved in movement control, and its deficiency is the primary cause of motor symptoms in Parkinson disease. Here we report development of an animal model of acute severe dopamine deficiency by using mice lacking the dopamine transporter. In the absence of transporter-mediated recycling mechanisms, dopamine levels become entirely dependent on de novo synthesis. Acute pharmacological inhibition of dopamine synthesis in these mice induces transient elimination of striatal dopamine accompanied by the development of a striking behavioral phenotype manifested as severe akinesia, rigidity, tremor, and ptosis. This phenotype can be reversed by administration of the dopamine precursor, L-DOPA, or by nonselective dopamine agonists. Surprisingly, several amphetamine derivatives were also effective in reversing these behavioral abnormalities in a dopamine-independent manner. Identification of dopamine transporter- and dopamine-independent locomotor actions of amphetamines suggests a novel paradigm in the search for prospective anti-Parkinsonian drugs.

Treatment of hemifacial spasm with botulinum A toxin. Results and rationale.

Science.gov (United States)

Gonnering, R S

1986-01-01

Hemifacial spasm is characterized by unilateral, periodic, tonic contractions of facial muscles, thought to be caused by mechanical compression at the root-exit zone of the facial nerve. Electrophysiologic abnormalities such as ectopic excitation and synkinesis are typical. Although posterior fossa microsurgical nerve decompression is successful in bringing about relief of the spasm in most cases, it carries a risk to hearing. As an alternative treatment, 15 patients with hemifacial spasm were given a total of 41 sets of injections with botulinum A toxin, with a mean follow-up of 14.3 +/- 1.1 months. Relief of symptoms lasted a mean of 108.3 +/- 4.2 days. Mild transient lagophthalmos and ptosis were the only complications. Although the exact mechanism of its action and beneficial effect is speculative at this time, botulinum A toxin appears to offer an effective, safe alternative to more radical intracranial surgery for patients with hemifacial spasm.

2014-05-01

Muller muscle-conjunctival resection (MCR) is a surgical technique to correct mild and moderate ptosis. In this study, tear function tests and ocular surface are evaluated in patients who underwent unilateral surgery. Sixteen patients with normal preoperative tear function who underwent unilateral MCR were evaluated prospectively. The fellow eyes of the patients were taken as the control group. A dry eye assessment questionnaire, Schirmer testing, tear film break-up time, fluorescein stain, Rose-Bengal stain, and conjunctival impression cytology were used to assess the tear film functions and ocular surface changes in the operated and non-operated eyes. There was no statistically significant difference in the tear function tests and goblet cell densities between the operated and non-operated eyes. The results indicate that an MCR procedure has no apparent effect on tear function tests and goblet cell density in patients with normal preoperative tear function.

Patrinely, J R; Koch, D D

Ocular adnexal amyloidosis is characterized by amyloid deposition within the deep connective tissue layers of the eyelids, conjunctiva, and anterior orbit. Management of advanced cases has traditionally been unsatisfactory, with either no surgery offered because of fear of hemorrhage or an en bloc resection performed of the entire involved area. We present two cases of advanced periorbital amyloidosis successfully managed by preserving the anatomic planes of the eyelids and meticulously debulking the deposits with a spooned curette. Lax eyelid tendons and aponeuroses were simultaneously repaired, and no sacrifice of eyelid tissues was necessary. One patient remained asymptomatic for 2 years after surgery before developing early reaccumulation in the lower eyelids. The other patient required additional eyelid debulking and ptosis revision 8 months after surgery, but was in stable condition at follow-up 2 years after surgery. This technique offers safe, easily repeatable, nondestructive treatment for advanced periocular amyloidosis.

We describe a rare case of HCV-related recurrent multiple hepatocellular carcinoma (HCC) metastasizing to the skull base involving multiple cranial nerves in a 50-year-old woman. The patient presented with symptoms of ptosis, fixation of the right eyeball, and left abducens palsy, indicating disturbances of the right oculomotor and trochlear nerves and bilateral abducens nerves. Brain contrast-enhanced computed tomography (CT) revealed an ill-defined mass with abnormal enhancement around the sella turcica. Brain magnetic resonance imaging (MRI) disclosed that the mass involved the clivus, cavernous sinus, and petrous apex. On contrast-enhanced MRI with gadolinium-chelated contrast medium, the mass showed inhomogeneous intermediate enhancement. The diagnosis of metastatic HCC to the skull base was made on the basis of neurological findings and imaging studies including CT and MRI, without histological examinations. Further studies may provide insights into various methods for diagnosing HCC metastasizing to the craniospinal area.

Ligneous conjunctivitis (LC) is a rare form of bilateral chronic recurrent disease in which thick membranes form on the palpebral conjunctiva and other mucosal sites. We report the clinical features and describe the management of two cases. Case 1 was an 8-month-old patient with bilateral membranous conjunctivitis. Case 2 was a 5-year-old patient with unilateral membranous conjunctivitis, esotropia, mechanical ptosis and complicated cataract, and had been treated with a number of medications. Histological investigation of the membrane in both cases showed LC. Treatments with amniotic membrane transplantation and institution of topical cyclosporine have shown good response. There has been complete resolution of the membranes with no recurrence at the end of 40- and 28-month follow-ups, respectively. No treatment related side effects were seen. Thus, it appears that amniotic membrane transplantation and topical cyclosporine are effective alternatives for the treatment of LC. PMID:23202401

Full Text Available Noonan Syndrome is a rare, autosomal dominant disorder characterized by short stature, facial abnormalities, congenital heart defects and urogenital malformations. Ocular changes occur in 95% of patients and usually include hypertelorism, ptosis, refractive errors, strabismus, amblyopia, rarely nystagmus, colobomas, cataracts, optic nerve drusen. Case report: We present a case of a boy, 10 months old, referred by the pediatrician because of strabismus. During the general examination of the head and face, we noted that the ears were low-set, and the lower jaw was slightly smaller. Ophthalmological examination revealed hypertelorism, left eye esotropia, hyperopia, and optic disc pit. Other associated malformations were: dilatation of both pyelons, cryptorchidism, pulmonary stenosis. Genetic analysis confirmed the diagnosis of Noonan syndrome. The variety of clinical manifestations of this syndrome indicates that a multidisciplinary approach is necessary for diagnosis, treatment, and follow-up of these patients.

The dynamic behavior of two stations in El Penol-Guatape reservoir was studied during a year. The station one was located to the entrance of the Nare River (main tributary to the reservoir) and the station two in the area denominated Sun Island (with mainly lentic characteristics). In each station monthly samplings were done with the purpose of calculating two hydro biologics parameters and some models of loads of nutritients and of eutrophication were applied. According to the study, it was established that in the in the station one the rate assimilation of nutritious by microorganisms and the sedimentation rate of chlorophylled organisms were more elevated that in the station two. In general, it was found that the primary production in the station one was limited by the phosphorous and there were limitations for nitrogen during five months and seven months by the phosphorous in the station two. Starting from the model of prediction of the eutrophycation, in tropical warm lakes, it was found that El Penol Guatape reservoir is oligo productive

del Castillo, Daniela L; Flores, David A; Cappozzo, Humberto L

2014-12-01

The aim of this work was to study the postnatal ontogenetic development of Pontoporia blainvillei skull, identifying major changes on shape, and relating them to relevant factors in the life history of the species. We analyzed a complete ontogenetic series (73♂, 83♀) with three-dimensional geometric morphometric techniques. Immature dolphins showed a very well-developed braincase and a poorly developed rostrum, and the principal postnatal changes affected the rostrum and the temporal fossa, both structures implied functionally to the feeding apparatus, thus suggesting a specialized mode for catch fast prey in P. blainvillei. Osseous elements associated with sound production were already well developed on immature dolphins, suggesting the importance of this apparatus since the beginning of postnatal life. Sexual dimorphism was detected on both shape and size variables. Females were bigger than males, in accordance with previous studies. Shape differences between sexes were found on the posterior part of premaxillaries and external bony nares (P < 0.01), suggesting that this sexual dimorphism is related to differences on vocalization capabilities. © 2014 Wiley Periodicals, Inc.

Measurements of 230 Th, 87 Sr/ 86 Sr and twenty-four metals were made on cores from the Nares Abyssal Plain. The sediment is characterized by slowly-accumulating pelagic red clays and rapidly deposited grey clays transported by turbidity currents. Despite their colour differences and the enrichment of certain elements in the red clays, Sr isotope evidence demonstrates that the clays have the same terrigenous origin. The excesses of metals in the red clays have been attributed to metal removal from the water column and a comparison with the grey clays has enabled the authigenic fluxes of metals to be estimated. The results are given for the elements Mn, Fe, Cu, Co, Ni, Zn, V, Sr, Ce, La, Nd, Sm, Eu, Gd, Dy, Er and Yb. Authigenic fluxes of Y, Nb, Cr, Zr, Rb, U and Th were not resolvable. Fluxes appear to be near constant on the Plain but comparison with other areas shows that they are quite variable both between and within ocean basins. The chief factor controlling authigenic fluxes is discussed. (author)

Mycoplasma iguanae was the suspected etiology of spinal disease in feral iguanas (Iguana iguana) from Florida. In an experimental infection study, juvenile iguanas were inoculated with M. iguanae intravenously or by instillation into the nares. Blood samples obtained at intervals postinoculation were all culture negative for mycoplasma. Gross anatomic and histologic findings at necropsy 12 wk postinoculation were unremarkable. Mycoplasmas were cultured in high numbers from the posterior choanae and upper trachea of some inoculated and control iguanas at necropsy. The 16S rDNA gene sequence of these isolates revealed they were all a previously undescribed strain, Mycoplasma insons proposed species nova. M. iguanae. Mycoplasma iguanae was not recovered from the conjunctivae, choanae, trachea, lung, coelomic cavity, blood, heart, liver, spleen, limb joints, brain, or spinal cord of inoculated iguanas, and the iguanas did not seroconvert. We conclude that M. iguanae is unlikely to be an agent of acute disease in iguanas and that M. insons can be considered as normal flora in the respiratory tract of iguanas.

Deep ocean model penetrator experiments

1986-01-01

Preliminary trials of experimental model penetrators in the deep ocean have been conducted as an international collaborative exercise by participating members (national bodies and the CEC) of the Engineering Studies Task Group of the Nuclear Energy Agency's Seabed Working Group. This report describes and gives the results of these experiments, which were conducted at two deep ocean study areas in the Atlantic: Great Meteor East and the Nares Abyssal Plain. Velocity profiles of penetrators of differing dimensions and weights have been determined as they free-fell through the water column and impacted the sediment. These velocity profiles are used to determine the final embedment depth of the penetrators and the resistance to penetration offered by the sediment. The results are compared with predictions of embedment depth derived from elementary models of a penetrator impacting with a sediment. It is tentatively concluded that once the resistance to penetration offered by a sediment at a particular site has been determined, this quantity can be used to sucessfully predict the embedment that penetrators of differing sizes and weights would achieve at the same site

Resection and Primary Closure of Edematous Glossoepiglottic Mucosa in a Dog Causing Laryngeal Obstruction.

Schabbing, Kevin J; Seaman, Jeffrey A

An approximately 22 mo old male neutered English bulldog was evaluated for acute onset of dyspnea with suspected brachycephalic obstructive airway syndrome (BOAS). Laryngoscopic exam revealed diffuse, severe edema and static displacement of redundant glossoepiglottic (GE) mucosa causing complete obstruction of the larynx and epiglottic entrapment. Static displacement of the GE mucosa was observed and determined to be the overriding component of dyspnea in this patient with BOAS. Resection and primary closure with two separate, simple continuous sutures of the GE mucosa were performed. Resection and primary closure of the GE mucosa resolved the acute onset of dyspnea in this patient. Surgical correction of the stenotic nares, elongated soft palate, and everted laryngeal saccules were performed under the same anesthetic procedure. Static displacement of the GE mucosa may occur in patients with BOAS. Surgical resection and closure of the GE mucosa resolved this patient's dyspnea and is recommended in airway obstruction. It remains to be determined if primary closure and subsequent tensioning or scar tissue of the GE mucosa results in further complications related to restricted epiglottic movement.

Coptobrycon bilineatus (Ellis, 1911 (Characiformes: Characidae: redescription and comments on its phylogenetic relationships

Directory of Open Access Journals (Sweden)

Francisco Langeani

Full Text Available Coptobrycon bilineatus (Ellis, 1911 is redescribed on the basis of specimens from the District of Paranapiacaba, Municipality of Santo André, upper rio Tietê, and additional ones recently collected in a small coastal river system of Serra do Mar, very near the headwaters of the rio Tietê. The genus was compared to other Characidae lacking a supraorbital, and it seems to be more phylogenetically related to Grundulus based on the possession of various putative apomorphic character states related to: the absence of a rhinosphenoid and fourth, fifth (sometimes and sixth infraorbitals; nasal pores separated; nares with up to six nasal lamellae; cephalic laterosensory system poorly developed on supraorbital and infraorbital series; and a globose scapula. Furthermore, Coptobrycon and Grundulus are characterized by the absence of the adipose fin, of the supraorbital laterosensory series on the parietal, and of the humeral spot, and by the reduction of lateral musculature in front of the first pleural rib and between the first and second pleural ribs. Biogeographic comments are also provided.

Laser rhinoscopy was used to treat a nasal obstruction in a captive California sea lion (Zalophus californianus). The rehabilitated, adult, female sea lion developed mucopurulent, intermittent, bilateral nasal discharge and functional nasal obstruction 20 mo after acquisition by the Aquarium of the Pacific in Long Beach, California. A 3-mm-thick soft tissue structure spanning the region between the soft and hard palates, a deviated nasal septum, and several nasopharyngeal polyps were identified. Biopsies and cultures of the obstructive web showed ulcerative granulation tissue with suppurative inflammation, bacterial infection, and a partial section of an arthropod larva (not speciated). Laser rhinoscopy was performed to relieve the caudal nasopharyngeal obstruction and ablate the polyps. The sea lion appeared to breathe through the nares with lessened nasal discharge for a period of 6 wk after laser therapy, but within 8 wk the mucopurulent nasal discharge returned, the obstruction had reformed, and the sea lion was euthanized. Postmortem examination confirmed antemortem diagnoses of caudal nasopharyngeal obstruction secondary to inflammatory tissue; however, no additional sections of arthropod parasites were located microscopically.

The goal of the study was to investigate whether cigarette smoking alters oral and nasal microbial diversity, composition, and structure. Twenty-three current smokers and 20 never smokers were recruited. From each subject, nine samples including supra and subgingiva plaque scrapes, saliva, swabs from five soft oral tissue sites, and one nasal swab from both the anterior nares were collected. 16S rRNA V3-V4 region was sequenced for microbial profiles. We found that alpha diversity was lower in smokers than in nonsmokers in the buccal mucosa, but in other sample sites, microbial diversity and composition were not significantly different by smoking status. Microbial profiles differed significantly among eight oral sites. This study investigates the effect of cigarette smoking on different sites of the oral cavity and shows a potential effect of cigarette smoking on the buccal mucosa microbiota. The marked heterogeneity of the oral microbial ecosystem that we found may contribute to the stability of the oral microbiota in most sites when facing environmental perturbations such as that caused by cigarette smoking.

Mixing height measurements from UHF wind profiling radar

Mixing height in convective boundary layers can be detected by wind profiling radars (profilers) operating at or near 915 MHZ. We have made such measurements in a variety of settings including Alabama in 1992; Nova Scotia, Canada, during the North Atlantic Regional Experiment (NARE) 1993; Tennessee during the Southern Oxidant Study (SOS) 1994; near a 450 m tower in Wisconsin in 1995; and extensively in Illinois during the Flatland95, `96, and `97 experiments, as well as continuous operations at the Flatland Atmospheric Observatory. Profiler mixing height measurements, like all measurements, are subject to some limitations. The most important of these are due to rainfall, minimum height, and height resolution. Profilers are very sensitive to rain, which dominates the reflectivity and prevents the mixing height from being detected. Because the best height resolution is currently 60 m and the minimum height is 120-150 m AGL, the profiler is not suited for detecting mixing height in stable or nocturnal boundary layers. Problems may also arise in very dry or cold environments. (au) 12 refs.

[Palatine amygdalectomy through the ages].

Willemot, J

1991-01-01

This paper describes the development of the techniques of amygdalectomy through the ages. It would appear that Susruta de Bénares performed such an operation as early as the first century, but I personally have no documents on him. On the other hand, the operation is described in scrupulous detail by Celse, at the same period, and was not greatly different from our current dissection. The Judeo-Arab world was familiar with amygdalectomy from the very beginning, and the techniques of Abulcassis, Avicenne and Haly Abbas used dissection, pulling-out and cauterization as early as the 10th century. Guillemeau, a student of Paré, was the first to propose a ligature. In the 18th century, Benjamin Bell remained faithful to the ligature technique, and devised on uvulotome, which gave Physick the idea of an amygdalotome, from which derived the instrument of Sluder-Ballenger, incorrectly called the guillotine, given that its principle was based on pulling-out rather than cutting. Nevertheless, dissection remains today the technique most widely employed.

Full Text Available Coagulase-negative staphylococci (CoNS have been identified as a major cause of nosocomial infections. Nasal carriage of CoNS in nurses and physicians is known to be an important risk factor for potential hospital infections. This study was carried out to investigate the prevalence of nasal carriage of uncommon coagulase-negative staphylococci among nurse and physician staffs of Tehran University Hospitals. A total of 116 CoNS were isolated from anterior nares of the study participants working in different wards of the hospitals. Thirteen uncommon CoNS were identified using phenotypic and biochemical methods, were subsequently confirmed by API kits. Staphylococcus xylosus, Staphylococcus haemolyticus, and Staphylococcus capitis species accounted for 53.85%, 30.77%, and 15.38% from the isolates, respectively. Six isolates (46.15% were found to be resistant to methicillin. In conclusion, screening of healthcare workers for uncommon CoNS colonization along with identification and testing for susceptibility of cultured isolates is of paramount importance in strengthening effective nosocomial infection control and prevention measures.

Methicillin-resistant Staphylococcus aureus (MRSA) is a nosocomial pathogen that has become increasingly prominent in hospitals and the community. HIV-positive patients may be one of the most MRSA-susceptible populations because of their immunocompromised status. At the Communicable Disease Centre, Tan Tock Seng Hospital, Singapore, we implemented a universal MRSA screening program and performed a case-control study to identify risk factors for MRSA colonization among 294 HIV patients at admission from January 2009 to January 2010. Among 54 HIV-positive patients who were MRSA positive at hospital admission, 16 (29.6%) were positive at the nares/axilla/groin (NAG; one combined swab), 14 (25.9%) were NAG and perianal positive, 3 (5.6%) were NAG and throat positive, 10 (18.5%) were NAG, perianal, and throat positive, 6 (11.1%) were throat positive, and 5 (9.3%) were perianal positive. Upon multivariate analysis, we found that age [odds ratio (OR)=1.04, 95% confidence interval (CI): 1.01-1.07, p=0.006] and CD4 count hospital admission.

Feasibility of high level radioactive waste disposal in deep sea sediments

Buckley, D.E.

1987-01-01

For the past ten years, an international program has been conducted to investigate the concept feasibility for disposing of spent nuclear fuel waste in deep ocean sediments. These studies by the Seabed Working Group were coordinated by the Nuclear Energy Agency of the Organization for Economic Cooperation and Development. Penetrators have been considered as the primary method of waste emplacement. This required emphasis on studies of the nature of the plastic sediments which would form the primary barrier to the release of radionuclides into the biosphere. Site qualification guidelines, included criteria for tectonic and sedimentary stability over periods of at least 10 5 years. Using these guidelines two potential areas were identified: one in the Madeira Abyssal Plain; and one in the Southern Nares Abyssal Plain, both in the North Atlantic. The sediment barrier properties are quite different in terms of dominant mineralogy (carbonates in MAP, and silicous clays in SNAP). The MAP is dominated by thick wide-spread turbidites, but SNAP is dominated by thin discontinuous turbidites

Full Text Available Aim: The aim of this study was to figure the prevalence, phenotypic and genotypic antibiotic resistance (AR pattern of Staphylococcus aureus isolated from bovine and swine nares. Materials and Methods: Colonies with typical morphology on Baird-Parker agar supplemented with egg-yolk tellurite emulsion were selected and biochemically/genotypically identified as S. aureus. These strains were further subjected to epsilometer test for their sensitivity to various clinically important antibiotics and antibiotic susceptibility testing for amoxicillin/clavulanic acid, and double-disk diffusion testing was performed by the standard disc diffusion method following CLSI guidelines. S. aureus strains were also tested for the presence of AR genes, viz., blaZ, mecA, aacA-aphD, erm (ermA, ermB, ermC, tet (efflux genes tetK and tetL, tetM and tetO of the ribosomal protection family, and vanA. Results: The nasal cavities of 17 out of 47 randomly selected bovine and 20 out of 28 randomly selected swine were positive for S. aureus, representing the prevalence of 36.2% (95% confidence interval [CI]: 22.5-49.9 and 71.4% (95% CI: 54.7-88.1, respectively. Most of the S. aureus strains showed higher resistance to penicillin (94.6%, minimal inhibitory concentration [MIC] =1.5 μg/ml followed by ciprofloxacin (56.7%, MIC =32 μg/ml and tetracycline (18.9%, MIC =32 μg/ml. About 10-15% of the strains were resistant to gentamicin (MIC 16 μg/ml and oxacillin (MIC 6-8 μg/ml. None of the strains were resistant to vancomycin (MIC 0.25-1.5 μg/ml. In this study, 32.4% strains were resistant to three or more than three antibiotics and prevalence of this multi-drug resistant S. aureus was 45% (95% CI: 26.6-63.4 and 17.6% (95% CI: 6.7- 28.5 in swine and bovine nasal samples, respectively. Four strains from pigs were borderline oxacillin-resistant S. aureus MIC 6-8 μg/ml, but none were mecA positive. Two of these strains were β-lactamase hyperproducers. Among the resistance

Two patients suffering from SUNCT syndrome are presented. Some features are remarkable. The first patient was a 69-year-old man whose first crisis was located in the right supraorbital region. After a 4-month spontaneous remission, the pain returned to the upper part of the cheek, radiating to the supraciliary region on the same side, with lacrimation and conjunctival injection. Rhinorrhea was absent. The painful attacks were triggered by head movements. Clinical improvement occurred with carbamazepine treatment. The second patient was a 48-year-old woman whose painful attacks lasted from 30 to 45 seconds followed by a burning sensation lasting 2 hours. Autonomic signs such as conjunctival injection, lacrimation, and edema and ipsilateral ptosis of the upper lid were rather marked. There was never any rhinorrhea. Her attacks were triggered by head and eye movements. She responded to the administration of corticosteroids and carbamazepine. According to these features, the two patients had SUNCT syndrome, and the positive carbamazepine response suggests a relationship with trigeminal neuralgia.

Use of magnetic therapy in clinical neurology: literature review

Energy Technology Data Exchange (ETDEWEB)

Shogam, I.I.; Lenchin, V.N.; Baranovskaya, A.V.

1985-01-01

A literature survey is presented on the current status of magnetic therapy in clinical neurology. It is generally accepted that the high susceptibility of the nervous system to the magnetic field is due to a large extent to the automatic component. Furthermore, it has also become clear that glial cells are far more susceptible to magnetic fields than are neurons. Controversy prevails on the question of whether the therapeutic effectiveness of magnetic fields involves a direct mechanism of action or an indirect one via reflex mechanisms. Nevertheless, effectiveness of magnetic therapy has been demonstrated and generally accepted in cases dealing with lagophthalmia, ptosis, various neuralgia, radiculitis, neuritis, vascular and infectious pathology of the brain, and so forth. Basically, the effectiveness of such therapy is strongly dependent on the location and the nature of the pathologic process, as well as on the functional status of the autonomic nervous system. In view of this, effective magnetic therapy is highly dependent on individualization of a given approach. 111 References.

We report the case of a 21-year-old woman who presented with a drooping right upper eyelid and smaller-appearing right eye, evident since birth. Her visual acuity was 20/30 in the right eye and 20/20 in the left eye. In primary gaze she had a hypotropia of 25 Δ , with a marked elevation limitation and associated true upper lid ptosis of 3 mm. Under local anesthesia, the lateral rectus muscle was transposed to the superior rectus muscle and was augmented by a nonabsorbable suture attaching the superior rectus muscle and lateral rectus muscle 8 mm posterior to the insertion, accompanied by an inferior rectus recession. One year after surgery she was orthophoric in primary position and showed improvement in elevation. The surgical procedure can be performed at the same time as the inferior rectus recession and reduces the risk of anterior segment ischemia.

Acute muscular weakness in children

Directory of Open Access Journals (Sweden)

Ricardo Pablo Javier Erazo Torricelli

Full Text Available ABSTRACT Acute muscle weakness in children is a pediatric emergency. During the diagnostic approach, it is crucial to obtain a detailed case history, including: onset of weakness, history of associated febrile states, ingestion of toxic substances/toxins, immunizations, and family history. Neurological examination must be meticulous as well. In this review, we describe the most common diseases related to acute muscle weakness, grouped into the site of origin (from the upper motor neuron to the motor unit. Early detection of hyperCKemia may lead to a myositis diagnosis, and hypokalemia points to the diagnosis of periodic paralysis. Ophthalmoparesis, ptosis and bulbar signs are suggestive of myasthenia gravis or botulism. Distal weakness and hyporeflexia are clinical features of Guillain-Barré syndrome, the most frequent cause of acute muscle weakness. If all studies are normal, a psychogenic cause should be considered. Finding the etiology of acute muscle weakness is essential to execute treatment in a timely manner, improving the prognosis of affected children.

Case of Cytomegalovirus Infection Causing Isolated Oculomotor Nerve Palsy

Directory of Open Access Journals (Sweden)

Halil Sen

2014-06-01

Full Text Available The third cranial nerve is called the oculomotor nerve. The pathology is revealed by limitation of eye movement inward-up-down, mydriasis, loss of light reflex and ptosis. Oculomotor nerve pathologies are frequently seen in neurology practice and are situations that may be very difficult for differential diagnosis. Differential diagnosis first involves disqualifying intracranial etiologies by imaging because these intracranial etiologies may be situations that can result in death and should be primarily evaluated. If intracranial events are ruled out, generally rarer etiologic reasons with generally difficult differentiation should be researched. Viral infections are among the rare etiological reasons causing 3rd cranial nerve involvement. Our case was a 71-year old female with etiological research due to 3rd cranial nerve palsy. The patient with diabetes-linked immune deficiency was found to have cranial nerve involvement developed secondary to cytomegalovirus (CMV infection. We report this case as 3rd cranial nerve involvement is rarely observed developing linked to CMV infection.

Here we describe some unusual ocular manifestations of the disease in one patient. A young male with history of upper respiratory tract symptoms including epistaxis, nasal stuffiness and maxillary sinus pain presented with bilateral lacrimal gland abscess and ptosis. Lacrimal gland biopsy revealed granulomatous vasculitis. Lung cavities, positive cytoplasmic-antineutrophil cytoplasmic antibodies and high titers of serine proteinase-3 antibodies confirmed the diagnosis of WG. The patient developed dry eyes after a month of first presentation. There was no dryness of mouth, suggesting the absence of salivary gland involvement, and antinuclear antibodies as well as antibodies against Ro and La antigens classical of primary Sjogren′s syndrome were absent. Granulomatous vasculitis of lacrimal gland leading to abscess formation and dryness of eyes has not been described in WG and reflects the aggressive nature of inflammatory process in this disease.

Objective: To investigate the complications of thyroid-arterial embolization and their prevention and treatment. Methods: 61 cases of thyroid disorders received the therapy of thyroid-arterial embolization were retrospectively studied. The complications of arterial embolization during or after the procedure were analyzed. How to prevent and deal with these complications were discussed. Results: Sensitivity to contrast media occurred in 1 case and surgical arterial injury in 2. After embolization thyroid storm occurred in 1 patient and all other complications including headache (23 cases), toothache (11 cases), neckache (13 cases), hoarseness (37 cases) were caused by non-target arterial embolization with the most serious one of cerebral infarction (1 case) and another eyelid ptosis (1 case). The cerebral infarct one was treated with some vasodilating drugs and anti-coagulant, all others were given anti-symptomatics or no special treatment. Conclusions: Proper treatment should be ready during thyroid arterial embolization and given in time with occurrence of complications

Horner's syndrome results from paralysis of the ipsilateral sympathetic cervical chain (stellate ganglion) caused by surgery, drugs (mainly high concentrations of local anesthetics), local compression (hematoma or tumor), or inadequate perioperative positioning of the patient. It occurs in 100% of the patients with an interscalene block of the brachial plexus and can also occur in patients with other types of supraclavicular blocks.In this case report, we presented a case of Horner's syndrome after performing an ultrasound-guided infraclavicular brachial plexus block with 15 mL of bupivacaine 0.5%. It appeared 40 minutes after the block with specific triad (ptosis, miosis, and exophtalmia) and quickly disappears within 2 hours and a half without any sequelae. Horner's syndrome may be described as an unpleasant side effect because it has no clinical consequences in itself. For this reason anesthesiologists should be aware of this syndrome, and if it occurs patients should be reassured and monitored closely.

The improved understanding of the functional anatomy of the face and of the action of the botulinum toxin A leads us to determine a new injection procedure which consequently decreases the risk of eyebrow and eyelid ptosis and increases the toxin's injection possibilities and efficiencies. With less units of toxin, the technique herein described proposes to be more efficient on more muscles: variable toxin injections concentration adapted to each injected muscle are used. Thanks to a new procedure in the upper face, toxin A injection can be quite close to an endoscopic surgical action. In addition, interesting results are achievable to rejuvenate the lateral canthus with injection on the upper lateral tarsus, to rejuvenate the nose with injection at the alar base, the jawline and the neck region. Lastly, a smoothing effect on the skin (meso botox) is obtained by the anticholinergic action of the toxin A on the dermal receptors. Copyright © 2017. Published by Elsevier Masson SAS.

Reinforced orbitotemporal lift: contribution to midface rejuvenation.

Science.gov (United States)

Renó, Waldir Teixeira

2003-02-01

The changes in the aging face occur from progressive ptosis of the skin, fat, and muscle, in conjunction with bone absorption and cartilage atrophy. In the orbital region, hollowness and compartmentalization occur. Conventional face lift procedures correct only the skin flaccidity, and superficial musculoaponeurotic system techniques reposition the skin and platysma without repositioning the middle third of the face, creating an artificial jawline. Subperiosteal rhytidectomy disrupts the anatomy of the periorbita, which gives the patient a certain scarecrow aspect. Composite rhytidectomy associated with brow lift and blepharoplasty may offer better results, with improvement in the malar and orbital regions. The reinforced orbitotemporal lift (ROTEL) is a new procedure in a face lift that allows the orbicularis oculi muscle and all the structures connected to it to be elevated and stretched and the orbitotemporal skin to be raised, repositioning these structures and ending orbital compartmentalization. The result is an impressive improvement in the malar-orbitotemporal region, resulting in a natural and youthful appearance.

A recent syndromic condition with craniofacial dysmorphisms, comprising congenital ocular defect and neurodevelopmental delay named Helsmoortel-Van der Aa Syndrome (HVDAS) (OMIM#615873), has been described and molecularly defined, identifying pathogenic mutations in the ADNP gene (OMIM#611386) as biological cause. We report on two children, displaying intellectual disability (ID) and peculiar congenital eyes anomalies, both carrying a de novo nonsense mutation in the ADNP gene. The review of present and literature reports, suggests that the diagnosis of HVDAS should be suspected in patients with ID accompanied by behavioral features in the Autism Spectrum Disorder and distinctive craniofacial phenotype. Among dysmorphisms due to malformation of the periorbital region, ptosis appears to be particularly recurrent in HVDAS. Furthermore, the present patients could support the inclusion of the HVDAS associated with specific mutations clustering within a small ADNP genomic region among clinical conditions reminiscent of the blepharophimosis/mental retardation syndromes (BMRS).

Ocular myasthenia gravis is a localized form of myasthenia gravis, which is a postsynaptic disorder of the neuromuscular junction that causes fluctuating weakness of extraocular muscles resulting from autoimmune mechanisms. In women with myasthenia, changes in sex hormone levels and administration of corticosteroids can trigger or worsen symptoms of myasthenia gravis. To describe a case of seronegative ocular myasthenia gravis whose first symptom appeared a day after in vitro fertilization procedure. A 37-year-old woman suddenly developed mild ptosis and fluctuating diplopia that worsened in the evening. Before the development of symptoms, she had undergone in vitro fertilization procedure and had taken oral steroids. Ocular motility examination revealed an intermittent exotropia in primary gaze at both distance and near. The neostigmine test confirmed her diagnosis as ocular myasthenia gravis. When taking a history for young women with sudden onset of binocular diplopia, steroids and sex hormones should be taken into account, which may trigger or exacerbate symptoms of ocular myasthenia gravis.

Full Text Available The FOXL2 forkhead transcription factor is expressed in ovarian granulosa cells, and mutated FOXL2 causes the blepharophimosis, ptosis and epicanthus inversus syndrome (BPES and predisposes to premature ovarian failure. Inactivation of Foxl2 in mice demonstrated its indispensability for female gonadal sex determination and ovary development and revealed its antagonism of Sox9, the effector of male testis development. To help to define the regulatory activities of FOXL2, we looked for interacting proteins. Based on yeast two-hybrid screening, we found that FOXL2 interacts with PIAS1 and UBC9, both parts of the sumoylation machinery. We showed that human FOXL2 is sumoylated in transfected cell lines, and that endogenous mouse Foxl2 is comparably sumoylated. This modification changes its cellular localization, stability and transcriptional activity. It is intriguing that similar sumoylation and regulatory consequences have also been reported for SOX9, the male counterpart of FOXL2 in somatic gonadal tissues.

Full Text Available Retinoic acid is a derivative of vitamin A.Retinoic acid embryopathy is an association of malformations caused by the teratogenic effect of retinoic acid, a drug used for the treatment of cystic acne.Isotretinoin is also known as 13-cis-retinoic acid.The risk of malformations after exposure to oral isotretinoin has been evaluated to be around 20%.Affected infants may present craniofacial, central nervous system, cardiac, and thymus abnormalities. There is also an increased risk of spontaneous abortions and premature delivery. Isotretinoin may also have effects on child behavior in about 30-60% of children exposed to it. Termination of pregnancy may be considered in cases of pregestational and/or gestational exposure to isotretinoin.The authors present the case of an infant male who was the first child of young, healthy, unrelated parents, whose mother was exposed to isotretinoin in both pregestational and gestational periods.He had a developmental delay, craniofacial abnormalities (low-set and dysplastic ears with anteverted lobules, frontal upsweep, hypertelorism, flat nasal bridge and prominent filter and apparent articular hypermobility, more obvious in his knees. Brain magnetic resonance imaging showed absence of cerebellar vermis, midbrain dysplastic configuration with thickened superior cerebellar peduncles, decreased thickness of pons-midbrain transition, right cerebellar hemisphere dysplasia, mild decrease in corpus callosum thickness, and enlarged pericerebral subarachnoid space.The features described are compatible with isotretinoin embryopathy, according to the literature.This case aims to raise awareness about the use of teratogenic drugs in women of childbearing age, especially isotretinoin, and the importance of information regarding effective contraceptive methods, with compulsory pregnancy testing.

Full Text Available Con la presencia de asentamientos hidroeléctricos en su territorio, los municipios del oriente y nordeste antioqueño han visto afectada su estructura tributaria y territorial, a pesar de la reglamentación compen­satoria del sector eléctrico. Este artículo, analiza los efectos tributarios generados por la compensación del impuesto predial. Para lograrlo se revisan los montos recibidos por los municipios de las empresas generadoras y se realiza una indagación empírica del impuesto bajo los escenarios con y sin asenta­mientos hidroeléctricos. De esta forma se determina el diferencial tributario. Se concluye que, además de la insuficiencia de las transferencias para compensar la pérdida del capital natural de las cuencas hidroeléctricas, la expansión del sector eléctrico genera regresividad tributaria, por causa de privilegios y exenciones concebidos por las Leyes. With the presence of hydroelectric settlements in their territory, the municipalities of the eastern and northeastern regions of Antioquia have seen their fiscal and territorial structure affected despite the regulatory compensation established for the electric sector. This article analyses the taxation effects gener­ated by the compensation of property taxes. To do so, different sums received by different municipalities from generating companies are analyzed and an empiric tax analysis is done for both types of territories (with and without hydroelectric settlements. This is how the taxation differential is determined. It is also concluded that, besides the influence of transfers for compensating the loss of the natural capital of the hydroelectric basins, the expansion of the electric sector generates taxation digressivety due to the privileges and exemptions conceived by the law

Full Text Available Introduction: Neonatal nasal airway obstruction induces various degrees of respiratory distress. The management of this disease, including surgical repair, will depend on the severity and location of the obstruction. We describe here a case of congenital nasal nostril stenosis that required surgical repair for stenting of both nares after coanal atresia repair.   Case Report: A 2 days old female newborn referred to neonatal department of Tabriz Children’s Hospital affiliated to the University of Medical Sciences of Tabriz, Iran on the 3rd of December, 2011 immediately after birth with respiratory distress due to bilateral coanal atresia and nasal hypoplasia with very small nostrils. CT scan showed normal brain and bilateral choanal atresia with normal size Pyriform apertures.   Conclusion: Nasal obstruction can lead to airway compromise and respiratory distress. Congenital bony nasal deformities are being recognized as an important cause of newborn airway obstruction. Nasal hypoplasia is seen in many craniofacial syndromes. Although our patient had hypoplastic nostrils with respiratory distress due to bilateral coanal atresia, correction of hypoplastic nostrils was necessary for completing the operation of choanal atresia.

A new species of the genus Goniurosaurus, G. zhoui sp. nov., is described based on specimens collected from karst areas in Hainan Island, China. Quantitative comparison of morphological traits and egg size with two known endemic species in Hainan Island and other known congeners confirmed the distinctiveness of G. zhoui sp. nov., which has a moderate size with a snout-vent length of 93.4-97.4 mm; light purple-brown dorsal ground color in adults; a posteriorly protracted nuchal loop on nape; four faint, purple-gray body bands bearing dark purple spots between and on them; eight nasal scales surrounding nares; single internasal; 49-62 eyelid fringe scales; 130-140 scales around midbody; 11 granular scales surrounding the dorsal tubercles; 36-38 precloacal pores in males (absent in females); claws sheathed by four scales, two lateral scales long and curved. We provide the first data on the natural history of the new species and an expanded key to Goniurosaurus species on Hainan Island and the adjacent mainland. The discovery of the new species facilitates our understanding of the speciation process on continental islands.

Upper respiratory tract disease (URTD) caused by Mycoplasma agassizii is considered a threat to desert tortoise populations that should be addressed as part of the recovery of the species. Clinical signs can be intermittent and include serous or mucoid nasal discharge and respiratory difficulty when nares are occluded. This nasal congestion may result in a loss of the olfactory sense. Turtles are known to use olfaction to identify food items, predators, and conspecifics; therefore, it is likely that URTD affects not only their physical well-being but also their behavior and ability to perform necessary functions in the wild. To determine more specifically the impact nasal discharge might have on free-ranging tortoises (Gopherus agassizii), we compared the responses of tortoises with and without nasal discharge and both positive and negative for M. agassizii antibodies to a visually hidden olfactory food stimulus and an empty control. We found that nasal discharge did reduce sense of smell and hence the ability to locate food. Our study also showed that moderate chronic nasal discharge in the absence of other clinical signs did not affect appetite in desert tortoises.

Full Text Available Background: Nasal colonisation with community acquired methicillin resistant Staphylococcus aureus (CA-MRSA is being increasingly reported, especially in places where people are in close contact and where hygiene is compromised. The aim of this study was to find out prevalence of methicillin resistant S.aureus (MRSA colonising anterior nares of healthy subjects. Materials and Methods: Nasal swabs of healthy subjects were collected aseptically and cultured using standard microbiological protocols. Antibiotic susceptibility was done by Kirby-Bauer disc diffusion method according to CLSI guidelines. Methicillin resistance was detected by cefoxitin disc diffusion method and confirmed by minimum inhibitory concentration (MIC and amplification of mecA gene by PCR. Strain typing of MRSA strains was done by PFGE. Results: Out of 820 samples, S.aureus was isolated from 229 (27.92% subjects. Of the 229 isolates, 15 were methicillin resistant. All S. aureus isolates were susceptible to vancomycin. Nasal carriage of MRSA was found to be 1.83% among healthy population. The isolates were found to be polyclonal by PFGE analysis. Conclusion: High prevalence of MRSA is a cause of concern and strategies to interrupt transmission should be implemented.

Objective To estimate the frequency of MRSA transmission to gowns and gloves worn by healthcare personnel (HCP) interacting with nursing home residents in order to inform infection prevention policies in this setting Design Observational study Setting and Participants Residents and HCP from 13 community-based nursing homes in Maryland and Michigan Methods Residents were cultured for MRSA at the anterior nares and perianal or perineal skin. HCP wore gowns and gloves during usual care activities. At the end of each activity, a research coordinator swabbed the HCP’s gown and gloves. Results 403 residents were enrolled; 113 were MRSA colonized. Glove contamination was higher than gown contamination (24% vs. 14% of 954 interactions, pgloves. We identified high risk activities (OR >1.0, pglove contamination. Conclusions MRSA transmission from MRSA positive residents to HCP gown and gloves is substantial with high contact activities of daily living conferring the highest risk. These activities do not involve overt contact with body fluids, skin breakdown or mucous membranes suggesting the need to modify current standards of care involving the use of gowns and gloves in this setting.

The relationship among ammonia levels, cage-changing frequency, and bedding types is an important and potentially controversial topic in the laboratory animal science community. Some bedding options may not provide sufficient urine absorption and bacterial regulation to minimize ammonia production during the interval between cage changes. High intracage ammonia levels can cause subclinical degeneration and inflammation of nasal passages, rhinitis and olfactory epithelial necrosis in exposed mice. Here we sought to compare the effects of 4 commonly used bedding substrates (1/4-in. irradiated corncob, reclaimed wood pulp, aspen wood chips, and recycled newspaper) on ammonia generation when housing female C57BL/6 mice in static and individually ventilated caging. Intracage ammonia levels were measured daily for 1 wk (static cage experiment) or 2 wk (IVC experiment). The results of this study suggest that the corncob, aspen wood chip, and recycled newspaper beddings that we tested are suitable for once-weekly cage changing for static cages and for changing every 2 wk for IVC. However, ammonia levels were not controlled appropriately in cages containing reclaimed wood pulp bedding, and pathologic changes occurred within 1 wk in the nares of mice housed on this bedding in static cages.

Full Text Available Mariliasuchus amarali Carvalho & Bertini, 1999 , a Mesoeucrocodylia from the Adamantina Formation (Bauru Basin, Upper Cretaceous shows some adaptative features to terrestrial environments: short and high skull, lateral orbits, frontal external nares and reduction of the dental formula with specialization of the tooth crown morphology in incisiform, caniniform and molariform teeth. It has been included in the infraorder Notosuchia Gasparini, 1971. Three specimens of Mariliasuchus amarali, found near the municipality of Marília, São Paulo State were analysed. One of them, holotype of Mariliasuchus amarali (UFRJ DG 50-R, is a juvenile crocodylifom whereas the other two (UFRJ DG 105-R and UFRJ DG 106-R are adult animals. These fossils allowed an analysis of the ontogenetic development patterns of this species. It was performed a comparison betweeen the mandibular, laterotemporal and supratemporal fenestrae and the skull sculpturing in the three specimens. The results show that Mariliasuchus acquire in the course of its ontogeny a thicker and stronger skull. The caudal migration of the laterotemporal fenestra and the size increase of the supratemporal fenestra probably indicate a wider use or strength of the adductor muscles during seizing and food processing.

The purpose of this work was to identify parameters influencing the risk of late radiation side effects, fair or poor cosmetic outcomes (COs) and pain in breast cancer patients after breast-conserving therapy (BCT) and three-dimensional conformal radiotherapy (3D-CRT). Between 2006 and 2013, 159 patients were treated at the Hannover Medical School. Physician-rated toxicity according to the LENT-SOMA criteria, CO and pain were assessed by multivariate analysis. LENT-SOMA grade 1-4 toxicity was observed as follows: fibrosis 10.7 %, telangiectasia 1.2 %, arm oedema 8.8 % and breast oedema 5.0 %. In addition, 15.1 % of patients reported moderate or severe breast pain, and 21.4 % complained about moderate or severe pain in the arm or shoulder. In multivariate analysis, axillary clearing (AC) was significantly associated with lymphoedema of the arm [odds ratio (OR) 4.37, p = 0.011, 95 % confidence interval (CI) 1.4-13.58]. Breast oedema was also highly associated with AC (OR 10.59, p = 0.004, 95 % CI 2.1-53.36), a ptosis grade 2/3 or pseudoptosis and a bra size ≥ cup C (OR 5.34, p = 0.029, 95 % CI 1.2-24.12). A ptosis grade 2/3 or pseudoptosis and a bra size ≥ cup C were the parameters significantly associated with an unfavourable CO (OR 3.19, p = 0.019, 95 % CI 1.2-8.4). Concerning chronic breast pain, we found a trend related to the prescribed radiation dose including boost (OR 1.077, p = 0.060, 95 % CI 0.997-1.164). Chronic shoulder or arm pain was statistically significantly associated with lymphoedema of the arm (OR 3.9, p = 0.027, 95 % CI 1.17-13.5). Chronic arm and breast oedema were significantly influenced by the extent of surgery (AC). Ptotic and large breasts were significantly associated with unfavourable COs and chronic breast oedema. Late toxicities exclusive breast pain were not associated with radiotherapy parameters. (orig.)

Whipple disease is a granulomatous infectious disease caused by Tropheryma whipplei. The bacteria accumulate within macrophages, preferentially in the intestinal mucosa. Disease manifestation seems to be linked to immunological abnormalities of macrophages. We describe a patient with cerebral Whipple disease who presented with changes in mental status, confusion, inverse sleep-wake cycle, bilateral ptosis and vertical gaze palsy. Endoscopic biopsy sampling revealed Whipple disease in the gastric antrum but not in the duodenum. Whole blood stimulation displayed reactivity to T. whipplei that was at the lower end of healthy controls while reactivity of duodenal lymphocytes was not diminished. We propose that in cases of neurological symptoms suspicious of Whipple disease with normal duodenal and jenunal findings, biopsy sampling should be extended to the gastric mucosa. The robust reactivity of duodenal lymphocytes may have prevented our patient from developing small bowel disease, whereas the impaired reactivity in peripheral blood lymphocytes might yet explain the bacterial spreading to the central nervous system leading to the rare case of predominant neurological symptoms without relevant systemic involvement.

11p Microdeletion including WT1 but not PAX6, presenting with cataract, mental retardation, genital abnormalities and seizures: a case report

Full Text Available Abstract WAGR syndrome (Wilms' tumor, aniridia, genitourinary abnormalities and mental retardation and Potocki-Shaffer syndrome are rare contiguous gene deletion syndromes caused by deletions of the 11p14-p12 chromosome region. We present a patient with mental retardation, unilateral cataract, bilateral ptosis, genital abnormalities, seizures and a dysmorphic face. Cytogenetic analysis showed a deletion on 11p that was further characterized using FISH and MLPA analyses. The deletion (11p13-p12 located in the area between the deletions associated with the WAGR and Potocki-Shaffer syndromes had a maximum size of 8.5 Mb and encompasses 44 genes. Deletion of WT1 explains the genital abnormalities observed. As PAX6 was intact the cataract observed cannot be explained by a deletion of this gene. Seizures have been described in Potocki-Shaffer syndrome while mental retardation has been described in both WAGR and Potocki-Shaffer syndrome. Characterization of this patient contributes further to elucidate the function of the genes in the 11p14-p12 chromosome region.

1984-01-01

A case of the rare juvenile form of Kearns-Shy syndrome with progressive external ophthalmoplegia and lid ptosis, carditis, skeletal muscle weakness, seizures, mental subnormality, short stature, EEG abnormality and deafness is presented. Electromyography revealed a myopathic pattern. Histochemical studies on quadriceps biopsy specimens showed atrophy of type II fibers and ''ragged-red fibers.'' On electron microscopy these muscle cells were seen to contain an increased amount of glycogen particles and abnormal mitochondria were increased in number and size. It is of interest that abrupt deterioration of neurological findings such as seizures, mental subnormality, speech disturbance and deafness was present in our case. Computed tomographic scanning showed progressive changes of cerebral atrophy, low density of cerebral white matter and basal ganglia calcification, which were well associated with the clinical deterioration. A review of the literature also indicated that some patients with this syndrome showed abrupt neurological deterioration in childhood. Involvement of the central nervous system in this syndrome has to be considered as the cause of sudden deterioration and death in childhood. (author)

A 26-year-old male presented to us with defective vision in the left eye. He had best corrected visual acuity (BCVA) of hand movement (HM) in right eye and 6/9 in left eye. He had ptosis with ectropion in both eyes and relative afferent pupillary defect (RAPD) in right eye. Intraocular pressure (IOP) was 46 and 44 mmHg in right and left eye, respectively. Fundus showed glaucomatous optic atrophy (GOA) in right eye and cup disc ratio (CDR) of 0.75 with bipolar rim thinning in left eye. Systemic examination showed hyperextensible skin and joints, acrogeria, hypodontia, high arched palate, and varicose veins. He gave history of easy bruising and tendency to fall and history of intestinal rupture 5 years ago for which he had undergone surgery. He was diagnosed as a case of Type IV Ehler-Danlos syndrome (EDS) with open angle glaucoma. He underwent trabeculectomy in both eyes. This is a rare case that shows glaucoma in a patient of EDS Type IV. Very few such cases have been reported in literature.

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a rare multisystemic autosomal recessive disorder mainly caused by mutations in the nuclear gene TYMP, encoding thymidine phosphorylase. It generally appears in childhood and is clinically characterized by severe gastrointestinal dysmotility, cachexia, ptosis, progressive external ophthalmoplegia, peripheral neuropathy, and diffuse leukoencephalopathy on brain magnetic resonance imaging. The disease is clinically heterogeneous with the main symptoms being gastrointestinal, with an important weight loss. Symptoms might worsen rapidly, and a timely diagnosis is vital. However, patients report retrospectively their first symptoms before the age of 12 years, but the delay in diagnosis varies from 5 to 10 years. In the present study, we report a case of an adolescent with MNGIE, which was initially, and erroneously, diagnosed as anorexia nervosa. To make a timely and accurate differential diagnosis, we will discuss the clinical differences and similarities between MNGIE and anorexia nervosa and the importance of a multidisciplinary evaluation.

Full Text Available A right-sided aortic arch with an aneurysm of the aberrant subclavian artery is a rare disease. We report a case of Kommerell's diverticulum of an aberrant left subclavian artery in a patient with a right-sided aortic arch. Fewer than 50 cases have been reported in the literature. A number of operative strategies are described. Right thoracotomy provides good exposure and avoids the morbidity associated with bilateral thoracotomy or sternotomy and thoracotomy. In our patient with symptoms of dysphagia, syncope, and left subclavian steal syndrome, a left thoracotomy was used. The repair was accomplished by division of a left ligamentum arteriosum, obliteration of the Kommerell's aneurysm, and an aorto-subclavian bypass. Postoperative complications included left vocal cord palsy and Horner's syndrome. Hoarseness and left ptosis recovered spontaneously 3 months after surgery, and the patient remained symptom-free at the 1-year follow-up. We believe a left thoracotomy for direct repair of Kommerell's diverticulum is a simple and safe method without the increased morbidity found in other procedures.

The presence of male pattern baldness poses a significant challenge when attempting to optimize treatment of the upper third of the face. The purpose of this study is to demonstrate and discuss results of the endoscopic forehead lift in patients with male pattern baldness. This was a retrospective case series done in an academic medical center. Eleven patients with male pattern baldness (Norwood class IV-VII) underwent endoscopic forehead lift for forehead creases and brow ptosis. All patients achieved smoothing of the forehead and elevation of the brow with no scalp anesthesia at 1 month postoperatively. All patients were pleased with the healing of their incisions in midline, paramedian, and temporal regions. Alloplastic fixation devices used were visible postoperatively in 2 patients initially. The endoscopic forehead lift is a suitable approach for treating the upper third of the face in the presence of male pattern baldness. The use of alloplastic fixation devices may be used in this patient population, but other fixation methods should be considered. Copyright © 2012 Elsevier Inc. All rights reserved.

Baraitser-Winter syndrome (BRWS) is a rare condition affecting the development of the brain and the face. The most common characteristics are unusual facial appearance including hypertelorism and ptosis, ocular colobomas, hearing loss, impaired neuronal migration and intellectual disability. BRWS is caused by mutations in the ACTB and ACTG1 genes. Cerebro-fronto-facial syndrome (CFFS) is a clinically heterogeneous condition with distinct facial dysmorphism, and brain abnormalities. Three subtypes are identified. We report a female infant with striking facial features and brain anomalies (included polymicrogyria) that fit into the spectrum of the CFFS type 3 (CFFS3). She also had minor anomalies on her hands and feet, heart and kidney malformations, and recurrent infections. DNA investigations revealed c.586C>T mutation (p.Arg196Cys) in ACTB. This mutation places this patient in the spectrum of BRWS. The same mutation has been detected in a polymicrogyric patient reported previously in literature. We expand the malformation spectrum of BRWS/CFFS3, and present preliminary findings for phenotype-genotype correlation in this spectrum. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Full Text Available Sarcoidosis is a multisystemic granulomatous disease of unknown etiology which affects most frequently the hilar lymph nodes and lungs. Symptomatic involvement of the central nervous system may develop in patients diagnosed with sarcoidosis or it may be the initial manifestation of the disease. This is a case report of 48-year old female patient admitted to our clinic for evaluation of working ability. The patient had a total of 24 years of service and occupational exposure and she has been employed as supplies procurement officer. On admission, she complained of the following discomforts: eye-lid pain, intellectual fatigue, psychic uneasiness, forgetfulness, dyspnea and productive cough. Neurological findings indicated the presence of the right eye ophthalmoplegia, psychoorganic syndrome and neurosarcoidosis. Ophthalmological examination evidenced bilateral ptosis and presence of anisocoria. Magnetic resonance imaging revealed discrete focal lesions of the pons (paracentral left and parietal corona radiata of the left hemisphere. Based on performed examinations and diagnostics procedures, final evaluation of patient’s working ability concluded that the patient was not capable of psychic strains and jobs associated with material accountability.

2018-01-01

Full Text Available Ophthalmoplegic cranial neuropathy (OCN is a disease with unknown etiology, which manifests itself by episodes of intense headache, accompanied by completely or partially reversible dysfunction of the oculomotor nerve: ptosis, mydriasis and ophthalmoplegia. It is assumed that the pathology is demyelinating in nature, therefore in the International classification of headaches OCN excluded from rubric migraine and related to the painful cranial neuropathies. The question of the prevention and treatment of this disease is still controversial, the issue of the appointment of corticosteroids, calcium channel blockers and β-blockers, methods of surgical correction of strabismus and botulin therapy.The article describes OCN in an 11-year-old boy. In the clinical picture headache attacks were observed. These attacks were with signs of selective lesions of the oculomotor nerve on one side. These functional changes are recurrent, and fully regress between attacks. Laboratory and instrumental examinations revealed no pathology that could cause this symptom, including myasthenia. The described case demonstrates the classical picture of OCN with a favorable course and the partial damage of the oculomotor nerve on one side.

[Evaluation of the cosmetic effect of orbital endoimplantation after removal the eyeball].

Piskiniene, Raimonda

2006-01-01

The purpose of our study was to evaluate the cosmetic effect of endoimplantation after removal the eyeball. The removal of the globe creates anatomic and physiological alteration of the orbital tissue and orbital bones. A volume deficit occurs when an eye is enucleated. Deep upper lid sulcus, ptosis, lower lid laxity, and enophthalmus of the artificial eye together constitute the postenucleation socket syndrome, which creates an asymmetry of the face. The orbital prosthesis by placing it in the orbital cavity allows correcting volume deficit, so the implant with attached extraocular muscles, together with an artificial eye, creates an illusion of real eye. Forty patients were operated on in Clinic of Eye Diseases of Kaunas University of Medicine Hospital. Twenty patients underwent removal of the eye and procedure of orbital implant insertion (main group). Twenty patients had just an eyeball removal without insertion of an orbital implant (control group). There was a statistically significant difference in exophthalmometry data between main and control groups (14.20+/-2.73 vs. 10.35+/-1.23 mm, respectively; peyeball removal.

Blepharophimosis is a rare congenital anomaly of the palpebral fissure which is often associated with mental retardation and additional malformations. We report on a boy with blepharophimosis, ptosis and severe mental retardation carrying an unbalanced 4;10 translocation with terminal duplication of 10q [dup(10)(q25.1-->qter)] and monosomy of a small terminal segment of chromosome 4q [del(4)(34.3-->qter)]. Detailed clinical examination and review of the literature showed that the phenotype of the patient was mainly determined by the dup(10q). This paper reviews the chromosomal aberrations associated with BMR (blepharophimosis mental retardation) phenotypes. Searching different databases and reviewing the literature revealed 14 microscopically visible aberrations (among them UPD(14)pat) and two submicroscopic rearrangements causing blepharophimosis and mental retardation (BMR) syndrome. Some of these rearrangements-like the terminal dup(10q) identified in our patient or interstitial del(2q)-are associated with clearly defined phenotypes and can be well distinguished from each other on basis of clinical examination. This paper should assist clinicians and cytogeneticists when evaluating patients with BMR syndrome.

We describe a 27-year-old pregnant female with new onset of conjugate gaze deficit during the third trimester of pregnancy. Repetitive nerve stimulation tests, neostigmine tests, and acetylcholine receptor antibody assays were all negative. The patient delivered a normal healthy baby at a local clinic via cesarean section. The baby became hypotonic and had respiratory failure several minutes after birth. The result of acetylcholine receptor antibody was negative in the neonate. The neonate became healthy spontaneously and was extubated after 21 days of ventilation care. Two months after delivery, the mother developed ptosis and generalized symptoms and subsequent workup revealed she was muscle specific kinase (MuSK) antibody positive. The neonate was presumed to have an anti-MuSK-mediated transient neonatal myasthenia gravis. Although MuSK antibody testing is rarely indicated in ocular myasthenia gravis, MuSK antibody testing is necessary in pregnant women who are presumed ocular myasthenia gravis to warn occurrence of transient neonatal myasthenia gravis.

71-year-old woman with progressive left-sided, monocular diplopia and ptosis. Her symptoms mimicked ocular myasthenia, but she had an indirect carotid cavernous fistula (CCF). She was diagnosed with monocular myasthenia gravis (negative acetylcholinesterase antibody) after a positive ice test and started on Mestinon and underwent a thymectomy complicated by a brachial plexus injury. Months later, she developed left-sided proptosis and ocular bruit. She was urgently referred to neuro-interventional surgery and was diagnosed with an indirect high-flow left CCF, which was treated with Onyx liquid and platinum coil embolisation. Mestinon was discontinued. Her ophthalmic symptoms resolved. However, she was left with a residual left arm and hand hemiparesis and dysmetria secondary to a brachial plexus injury. Indirect CCF usually can present with subtle and progressive symptoms leading to delayed diagnosis or misdiagnosis. It is important for ophthalmologists to consider this differential in a patient with progressive ocular symptoms. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Full Text Available IgG4-related disease (IgG4-RD is a recently recognized group of conditions, characterized by tumor-like swelling of involved organs, lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, variable degrees of fibrosis, and elevated serum IgG4 concentrations. Currently IgG4-RD is recognized as a systemic condition that can affect several organs and tissues. Herein we report the case of a 34-year-old male patient who was admitted to our hospital with diffuse abdominal pain, weight loss, and painful stiffness in his neck. He had a history of tumoral mass of the left maxillary region, right palpebral ptosis with protrusion of the eyeball, and chronic dry cough for about 6 years. Laboratory tests revealed polyclonal hypergammaglobulinemia and increased serum IgG4 levels. Immunohistochemical staining of the maxillary biopsy was compatible with IgG4-RD. He had an excellent response to corticosteroid therapy. This case highlights that IgG4-RD should be included in the differential diagnosis with multisystem diseases.

Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways: direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal nerve developed without evidence of recurrence in CT scan. Ptosis and total ophthalmoplegia developed sequentially and the second operation was performed. It was suggested that the tumor was spread perineurally along the trigeminal nerve into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then Jung metastasis was diagnosed. She is alive for 9 years 5 months after first operation.

Goldberg-Shprintzen megacolon syndrome (GOSHS) (OMIM 609460) is characterized by a combination of learning difficulties, characteristic dysmorphic features and Hirschsprung's disease. Variable clinical features include iris coloboma, congenital heart defects and central nervous system abnormalities, in particular polymicrogyria. GOSHS has been attributed to recessive mutations in KIAA1279, encoding kinesin family member (KIF)-binding protein (KBP) with a crucial role in neuronal microtubule dynamics. Here we report on a 7-year-old girl with GOSHS as a result of a homozygous deletion of exons 5 and 6 of the KIAA1279 gene. She had been referred with the suspicion of an underlying neuromuscular disorder before the genetic diagnosis was established, prompted by the findings of motor developmental delay, hypotonia, ptosis and absent reflexes. Neurophysiological studies revealed unequivocal evidence of a peripheral axonal sensory motor neuropathy. We hypothesize that an axonal sensory motor neuropathy may be part of the phenotypical spectrum of KIAA1279-related GOSHS, probably reflecting the effects of reduced KBP protein expression on peripheral neuronal function. © 2015 Wiley Periodicals, Inc.

This study describes a method that not only generates an automatic and standardized crush injury in the skull base, but also provides investigators with the option to choose from a range of varying pressure levels. We designed an automatic, non-serrated forceps that exerts a varying force of 0 to 100 g and lasts for a defined period of 0 to 60 seconds. This device was then used to generate a crush injury to the right oculomotor nerve of dogs with a force of 10 g for 15 seconds, resulting in a deficit in the pupil-light reflex and ptosis. Further testing of our model with Toluidine-blue staining demonstrated that, at 2 weeks post-surgery disordered oculomotor nerve fibers, axonal loss, and a thinner than normal myelin sheath were visible. Electrophysiological examination showed occasional spontaneous potentials. Together, these data verified that the model for oculomotor nerve injury was successful, and that the forceps we designed can be used to establish standard mechanical injury models of peripheral nerves.

Conclusions:. The method described here may allow even inexperienced surgeons to achieve reconstruction of symmetrical, non-ptotic breasts with ease and in a short time. While the requirement of two surgeries is a potential disadvantage, our method will be particularly useful in cases involving TEs, i.e., delayed reconstruction or immediate reconstruction involving significant skin resection.

Small fractures in deep sea sediments: indicators of pore fluid migration along compaction faults

International Nuclear Information System (INIS)

Buckley, D.E.

1989-01-01

A long piston core taken from the Southern Nares Abyssal Plain, intersected four fractures in plastic sediments between 17 and 25 m below the sea floor. Faults have been identified from seismic reflection surveys of sediments in this area. The sampled fractures all occurred in oxidized brown clays. Each fracture consisted of a simple plane having apparent dips ranging from 52-63 0 . One fracture had a well developed pale brown alteration halo extending out to 1.5 cm along this plane. Two fractures had no apparent alteration halo, but one fracture appeared to have fine-scale anastomosing features surrounding the main slip plane. Selective chemical tests for labile metal content in sediments surrounding the fractures revealed that about 70% of the reducible manganese, and 40% of the reducible iron had been leached from the sediments in the alteration halo surrounding the fracture plane. These results suggest that reducing pore fluids had migrated along the fracture plane to cause the observed effects. Implications of this study are that compaction faults may act as episodic conduits for vertical advection of pore water during dewatering of unconsolidated sediments. This may be a significant factor to be considered in assessing the effectiveness of deep sea sediment barriers for radioactive waste disposal. (author)

2008-01-01

The geometric features and the distribution properties of pores in rocks were In-vestigated by means of CT scanning tests of sandstones. The centroidal coordl-nares of pores, the statistic characterristics of pore distance, quantity, size and their probability density functions were formulated in this paper. The Monte Carlo method and the random number generating algorithm were employed to generate two series of random numbers with the desired statistic characteristics and prob-ability density functions upon which the random distribution of pore position, dis-tance and quantity were determined. A three-dimensional porous structural model of sandstone was constructed based on the FLAC3D program and the information of the pore position and distribution that the series of random numbers defined. On the basis of modelling, the Brazil split tests of rock discs were carried out to ex-amine the stress distribution, the pattern of element failure and the inoaculation of failed elements. The simulation indicated that the proposed model was consistent with the realistic porous structure of rock in terms of their statistic properties of pores and geometric similarity. The built-up model disclosed the influence of pores on the stress distribution, failure mode of material elements and the inosculation of failed elements.

Otolaryngoscopic biopsy of nasopharyngeal carcinoma is a generalized method which may be associated with inadequate sampling of tissue and patient discomfort. So, we tried fluoroscopy-guided transnasal biopsy using bronchoscopic biopsy forcep and evaluated its safety and efficacy. Prospectively we performed fluoroscopy-guided transnasal biopsy in 11 patients who were radiographically suspected of nasopharyngeal carcinoma. The posterior wall of the nasopharynx was coated with barium sulfate under fluoroscopy. A flexible bronchoscopic biopsy forcep with a steerable guiding catheter which was used in removal of intrahepatic duct stones was inserted through the nare. After localization of the tip of the biopsy forcep at tumor site with fluoroscopy, a tissue specimen was obtained. We also tried CT guided biopsy in initial 2cases. Each patient had otolaryngoscopic biopsy to compare the biopsy result and patient discomfort. We could have sufficient amount of tissue for pathological evaluation in 10 of 11 patients by the first pass with the fluoroscopic technique. Contrarily, otolaryngoscopic biopsy was successful in 7 of 11 patients on single passage. Additionally, 2 patients had complaint in our method comparing with 9 patients in otolaryngoscopic biopsy. Fluoroscopy-guided transnasal biopsy of nasopharyngeal carcinoma using the bronchoscopic biopsy forcep is safe and accurate. It can be a appropriate method competing otolaryngoscopic biopsy

The respiratory tract deposition model proposed by the ICRP Task Group

1990-11-01

The Task Group has developed a new model of the deposition of inhaled aerosols in each anatomical region of the respiratory tract. The model is used to evaluate the fraction of airborne activity that is deposited in respiratory regions having distinct retention characteristics and clearance pathways: the anterior nares, the extrathoracic airways of the naso- and oropharynx and larynx, the bronchi, the bronchioles, and the alveolated airways of the lung. Drawn from experimental data on total and regional deposition in human subjects, the model is based on extrapolation of these data by means of a detailed theoretical model of aerosol transport and deposition within the lung. The Task Group model applies to all practical conditions, and for aerosol particles and vapors from atomic size up to very coarse aerosols with an activity median aerodynamic diameter of 100 μm. The model is designed to predict regional deposition in different subjects, including adults of either sex, children of various ages, and infants, and also to account for anatomical differences among Caucasian and non-Caucasian subjects. The Task Group model represents aerosol inhalability and regional deposition in different subjects by algebraic expressions of aerosol size, breathing rates, standard lung volumes, and scaling factors for airway dimensions. 35 refs., 13 figs., 2 tabs

Antibiotics used to reduce nasal colonization by Staphylococcus aureus in patients before admission are inappropriate for carriage reduction on a regular basis within a hospital community. Effective nonantibiotic alternatives for daily use in the nares will allow reduction of this bacterial source to be addressed. Our study tested the effectiveness of a nonantibiotic, alcohol-based antiseptic in reducing nasal bacterial carriage in health care professionals (HCPs) at an urban hospital center. HCPs testing positive for vestibular S aureus colonization were treated 3 times during the day with topical antiseptic or control preparations. Nasal S aureus and total bacterial colonization levels were determined before and at the end of a 10-hour workday. Seventy-eight of 387 HCPs screened (20.2%) tested positive for S aureus infection. Of 39 subjects who tested positive for S aureus infection who completed the study, 20 received antiseptic and 19 received placebo treatment. Antiseptic treatment reduced S aureus colony forming units from baseline by 99% (median) and 82% (mean) (P antiseptic was effective in reducing S aureus and total bacterial carriage, suggesting the usefulness of this approach as a safe, effective, and convenient alternative to antibiotic treatment.

Th-230 dating of ∼30 m long piston cores taken from two North Atlantic abyssal plains during the ESOPE cruise

Nozaki, Yoshiyuki; Sato, Mitsuyoshi; Shimooka, Kenji.

1987-01-01

Two sediment cores longer then 20 meters, obtained from two abyssal plains of the North Atlantic during the ESOPE (Etude des Sediments Oceaniques par Penetration) cruise, are analyzed for U and Th isotopes. In the Maderia Abyssal Plain sediment, excess 230 Th data do not show a simple exponential decrease with depth, being reflected by complex depositional history of the sediments, and hence the Th isotope data can only weakly constrain the rate of sediment accumulation. Relatively low 230 Th concentration in the top 5 meters may be caused by rapid accumulation of turbiditic materials. That a significant excess 230 Th exists even at depths of ∼20 m in the core suggests that the average sedimentation rate is high, perhaps ∼10 of centimeters per thousand years. This high rate of sediment accumulation has resulted largely from frequent turbidites, and not from pelagic clay sedimentation. In the Nares Abyssal Plain sediment, excess 230 Th relative to 234 U has been found down to ∼5 m, showing its almost exponential decrease with depth. Based on excess 230 Th distribution, an average sedimentation rate for the core is estimated to be 1.2 ± 0.3 cm-10 3 y. (Nogami, K.)

Radiological assessment of the consequences of the disposal of high-level radioactive waste in subseabed sediments

1987-01-01

The radiological assessment of the seabed option consists in estimating the detriment to man and to the environment that could result from the disposal of high-level waste (HLW) within the seabed sediments in deep oceans. The assessment is made for the high-level waste (vitrified glass) produced by the reprocessing of 10 5 tons of heavy metal from spent fuel, which represents the amount of waste generated by 3333 reactor-yr of 900-MW(electric) reactors, i.e., 3000 GW(electric) x yr. The disposal option considered is to use 14,667 steel penetrators, each of them containing five canisters of HLW glass (0.15 m 3 each). These penetrators would reach a depth of 50 m in the sediments and would be placed at an average distance of 180 m from each other, requiring a disposal area on the order of 22 x 22 km. Two such potential disposal areas in the Atlantic Ocean were studied, Great Meteor East (GME) and South Nares Abyssal Plains (SNAP). A special ship design is proposed to minimize transportation accidents. Approximately 100 shipments would be necessary to dispose of the proposed amount of waste. The results of this radiological assessment seem to show that the disposal of HLW in subseabed sediments is radiologically a very acceptable option

This very successful cooperation between the two German institutions - both working continuously in the polar regions - was already established in Arctic projects, namely in northern Greenland. Also, since the late 1990's BGR conducted together with Canada airborne surveys as part of PMAP (Polar Margins Aeromagnetic Program), thematically linked to the predominantly geological CASE (Circum Arctic Structural Events) program of BGR. A joint project of GSC (Geological Survey of Canada) and BGR in the Nares Strait was a highlight of combined geological and aeromagnetic research addressing the still widely discussed Wegener fault between Greenland and Ellesmere Island and the extent of tertiary basins in the Nares Strait itself. BGR intends to continue its successful combined geological-geophysical work in both polar regions. The increasing logistic and financial challenges to work in these extreme areas will demand not only a continuation but an intensification of national and international collaboration.

PurposeCentral venous catheterization (CVC) is estimated to be performed in millions of patients per year. Swan-Ganz catheters used for CVC are most often inserted into the internal jugular vein and during this procedure they may come into contact with the sympathetic chain. This study aims to determine the incidence of Horner's syndrome in patients admitted to intensive care unit that have undergone internal jugular CVC insertion during their admission and to determine whether ultrasonography-assisted insertion has decreased the frequency of this complication.Patients and methodsA total of 100 prospective patients admitted to the ICU were examined for the presence of anisocoria and ptosis after undergoing recent CVC. Presence of Horner's syndrome was confirmed by testing with 0.5% apraclonidine and looking for the reversal of anisocoria.ResultsFrequency of Horner's syndrome after CVC was 2% in a sample of 100 prospectively examined patients.ConclusionHorner's syndrome remains a relatively rare but definitive complication of CVC. ICU physicians should be educated about its existence and prevalence and ophthalmologists should inquire about any history of ICU admission necessitating CVC insertion in any patient presenting with Horner's syndrome.

According to the International Headache Society, ophthalmoplegic migraine is recurrent attacks of headache with migrainous characteristics associated with paresis of one or more ocular cranial nerves (commonly the third nerve) in the absence of any demonstrable intracranial lesion. We report a patient with typical clinical features of ophthalmoplegic migraine. A 21-year-old man had right frontal throbbing headaches recurring twice a year. His headache lasted for 1 to 5 days and was followed by slight drooping of his eyelid and double vision that lasted for approximately 3 months. On examination he had ptosis and adduction paralysis of the right eye. Brain MRI revealed a thickened, enhancing right oculomotor nerve. He was treated with methylprednisolone 1000 mg/d IV for 5 days. Only 2 weeks later, clinical improvement was observed and 3 months later the oculomotor nerve enhancement resolved. Ophthalmoplegic migraine has been considered to have a microvascular, ischemic etiology, but more recently it has been reclassified as a demyelinating condition affecting the oculomotor. To our knowledge, this is the first ophthalmoplegic migraine case presented pretreatment and post-treatment with clinical photographic documentation and an MRI showing enduring thickening of the oculomotor nerve although symptoms and contrast enhancement resolved.

A 59-year-old man presented with feverish illness. His Glasgow Coma Scale was 15, had reduced visual acuity in the left eye with partial left ptosis and mild left hemiparesis with an extensor left plantar. Over 48 hours, he accrued multiple cranial nerves palsies and progressed to a flaccid paralysis necessitating admission to an intensive care unit.Cerebrospinal fluid (CSF) study showed 20 lymphocytes and raised protein. Viral and bacterial PCRs were negative. Samples for Lyme, blood-borne viruses, syphilis and autoantibodies were also negative. MRI brain showed T2 abnormalities within the brainstem. Nerve conduction studies revealed an acute motor and sensory axonal neuropathy pattern of Guillian Barre Syndrome (GBS). The patient was treated for both infective and inflammatory causes of brainstem encephalitis and GBS.Retrospective studies confirmed the presence of hepatitis E virus (HEV) RNA in CSF and serum studies showed positive HEV IgG and IgM prior to intravenous infusion. After 3 months of intensive rehabilitation, the patient was discharged home walking with a frame. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

The expanding phenotype of mitochondrial myopathy.

DiMauro, Salvatore; Gurgel-Giannetti, Juliana

2005-10-01

Our understanding of mitochondrial diseases (defined restrictively as defects in the mitochondrial respiratory chain) continues to progress apace. In this review we provide an update of information regarding disorders that predominantly or exclusively affect skeletal muscle. Most recently described mitochondrial myopathies are due to defects in nuclear DNA, including coenzyme Q10 deficiency, and mutations in genes that control mitochondrial DNA (mtDNA) abundance and structure such as POLG and TK2. Barth syndrome, an X-linked recessive mitochondrial myopathy/cardiopathy, is associated with altered lipid composition of the inner mitochondrial membrane, but a putative secondary impairment of the respiratory chain remains to be documented. Concerning the 'other genome', the role played by mutations in protein encoding genes of mtDNA in causing isolated myopathies has been confirmed. It has also been confirmed that mutations in tRNA genes of mtDNA can cause predominantly myopathic syndromes and - contrary to conventional wisdom - these mutations can be homoplasmic. Defects in the mitochondrial respiratory chain impair energy production and almost invariably involve skeletal muscle, causing exercise intolerance, myalgia, cramps, or fixed weakness, which often affects extraocular muscles and results in droopy eyelids (ptosis) and progressive external ophthalmoplegia.

Our understanding of mitochondrial diseases (defined restrictively as defects of the mitochondrial respiratory chain) is expanding rapidly. In this review, I will give the latest information on disorders affecting predominantly or exclusively skeletal muscle. The most recently described mitochondrial myopathies are due to defects in nuclear DNA, including coenzyme Q10 deficiency and mutations in genes controlling mitochondrial DNA abundance and structure, such as POLG, TK2, and MPV17. Barth syndrome, an X-linked recessive mitochondrial myopathy/cardiopathy, is associated with decreased amount and altered structure of cardiolipin, the main phospholipid of the inner mitochondrial membrane, but a secondary impairment of respiratory chain function is plausible. The role of mutations in protein-coding genes of mitochondrial DNA in causing isolated myopathies has been confirmed. Mutations in tRNA genes of mitochondrial DNA can also cause predominantly myopathic syndromes and--contrary to conventional wisdom--these mutations can be homoplasmic. Defects in the mitochondrial respiratory chain impair energy production and almost invariably involve skeletal muscle, causing exercise intolerance, cramps, recurrent myoglobinuria, or fixed weakness, which often affects extraocular muscles and results in droopy eyelids (ptosis) and progressive external ophthalmoplegia.

Peribulbar anesthesia (PBA) has emerged as a safer option compared with intraconal retrobulbar block. Still, PBA may not be considered without risk. Numerous complications have been described when performing this technique. This report aims to describe a rare case of amaurosis and contralateral paralysis while attempting to perform a PBA. Male patient, 75-year old, physical status ASA II, undergoing cataract surgery by phacoemulsification with intraocular lens implantation. Sedated with fentanyl and midazolam and subjected to PBA. There were no complications during surgery. After finishing the procedure, the patient reported lack of vision in the contralateral eye. Akinesia of the muscles innervated by the cranial nerve pairs III and VI, ptosis, and medium-sized pupils unresponsive to light stimulus were observed. Four hours after anesthesia, complete recovery of vision and eyelid and eyeball movements was seen in the non-operated eye. During PBA, structures located in the intraconal space can be accidentally hit leading to complications such as described in the above report. Following the technical guidelines and using appropriate size needles may reduce the risk of such complication, but not completely. Copyright © 2016. Publicado por Elsevier Editora Ltda.

Full Text Available Third nerve paralysis has been known to be associated with a wide spectrum of presentation and other associated factors such as the presence of ptosis, pupillary involvement, amblyopia, aberrant regeneration, poor bell′s phenomenon, superior oblique (SO overaction, and lateral rectus (LR contracture. Correction of strabismus due to third nerve palsy can be complex as four out of the six extraocular muscles are involved and therefore should be approached differently. Third nerve palsy can be congenital or acquired. The common causes of isolated third nerve palsy in children are congenital (43%, trauma (20%, inflammation (13%, aneurysm (7%, and ophthalmoplegic migraine. Whereas, in adult population, common etiologies are vasculopathic disorders (diabetes mellitus, hypertension, aneurysm, and trauma. Treatment can be both nonsurgical and surgical. As nonsurgical modalities are not of much help, surgery remains the main-stay of treatment. Surgical strategies are different for complete and partial third nerve palsy. Surgery for complete third nerve palsy may involve supra-maximal recession - resection of the recti. This may be combined with SO transposition and augmented by surgery on the other eye. For partial third nerve, palsy surgery is determined according to nature and extent of involvement of extraocular muscles.

Facial ageing is a gradual process which could be due to intrinsic and extrinsic causes and it ultimately results in the appearance of activity induced tissue ptosis, wrinkles, epidermal and dermal artoply, dryness, senile lentigo, flushing, telangiectasia and enlarged pores. Moreover, freckles are frequently seen on the face and other sun exposed areas and it is characterized with incrreased melanin in the epidermis. Intense Pulsed Light (IPL)is the latest technology for selective photo-thermolysis as a non-ablative photo-rejuvenation. Thirty-four patients of age ranging between 35- 70 years with skin type ranging between III-V with or without freckles were treated with 3-5 sessions of IPL. Three weeks intervals were considered between every two succesive session. Irradiation wavelength was controlled using cutoff filters ranging from 535 to 580 nmwith a fluence of 25-35 j/cm-2. Significant improvement was demonstrated after 6 months by computerized image analysis compared with the baseline. IPL was found to be effective and saf treatment for fine wrinkles, facial freckles, telangiectasia, flushing as well as post-inflammatory hyper-pigmentation with a high satisfactory level and a relatively afew adverse effects

Identification of internal carotid dissection in patients with migraine--case report and literature review

Although patho-physiology of spontaneous internal carotid artery dissection (sICAD) is largely unknown, an association with migraine has been suggested but not proven. Migraine is a condition which is worth considering while one is hunting a possible cause for internal carotid artery dissection (ICAD) and it may be found more often than expected.2 To date it remains a diagnosis of exclusion in patients with migraine. As opposed to migraine with aura, migraine without aura is significantly more frequent among patients with SICAD. It has been suggested that ICAD produces stroke in 36-68% of patients as a result of occlusion of the artery at or near the site of the dissection, or embolization occurring distally from a dislodged fragment of thrombus. We report a 31-year old woman with headache and ptosis as initial symptoms. Magnetic resonance imaging (MRI) confirmed the diagnosis. Prompt treatment was instituted with anti-platelet agents and the patient had complete resolution of symptoms. Our case report highlights the importance of identifying the patients with ICD with history of migraine, in the absence of other risk factors and adds to the sparse literature currently available on the subject.

Optic nerve sheath meningiomas (ONSM) are rare tumors of the anterior visual pathway. Without treatment, tumor growth leads to progressive loss of visual acuity and blindness due to optic nerve compression. Case report: Patient, female, 42 years without other morbility , begins in 1992 with decreased visual acuity of the left eye, magnetic resonance imaging (MRI) showed enlargement of the left optic nerve sheath, suggestive of ONSM. On that occasion, orbit exploration failed, so it was decided to follow up with annual clinical and imaging controls. About ten years later, begins with progressive deterioration of visual acuity and visual field , with ptosis and ocular motor palsy of the left eye, confirmed with neuro-ophthalmological examinations. MRI shows tumor progression. A new surgical approach was discarded by the risk of visual worsening. A conformal radiotherapy was performed with a fractionated 54 Gy dose. Today, at age 65, after 24 years of follow up,13 post radiation therapy. clinical and radiological stability of ONSM is confirmed. Discussion: Conformal radiotherapy has been shown as an effective therapy, with fewer complications and better outcomes in the preservation of visual function in the long term follow up Radio-fluoro guided surgery in high grade gliomas

Glycogen storage disease type Ib (GSD Ib, OMIM 232220) is an inborn disorder of glucose metabolism, caused by mutations in the G6PT gene, encoding a glucose 6-phosphate transporter (G6PT). GSD Ib is mainly associated with fasting hypoglycaemia and hepatomegaly. Most GSD Ib patients also show neutropenia and neutrophil dysfunction and therefore are at risk of developing severe infections and inflammatory bowel disease (IBD). An increased risk for autoimmune disorders, such as thyroid autoimmunity and Crohn-like disease, has also been demonstrated, but no systematic study on the prevalence of autoimmune disorders in GSD Ib patients has ever been performed. We describe a 25-year-old patient affected by GSD Ib who developed 'seronegative' myasthenia gravis (MG), presenting with bilateral eyelid ptosis, diplopia, dysarthria, severe dysphagia, dyspnoea and fatigue. The repetitive stimulation of peripheral nerves test showed signs of exhaustion of neuromuscular transmission, particularly evident in the cranial area. Even in the absence of identifiable anti-acetylcholine receptor antibodies, seronegative MG is considered an autoimmune disorder and may be related to the disturbed immune function observed in GSD Ib patients.

Full Text Available Abstract Introduction The association of thymoma with myasthenia gravis (MG is well known. Thymoma with sarcoidosis however, is very rare. We presented an interesting case with coexisting thymoma, MG and sarcoidosis. Case presentation A 59-year-old female patient with a history of sarcoidosis was admitted to the hospital with a one-day history of sudden onset of right-sided partial ptosis and diplopia. Neurosarcoidosis with cranial nerve involvement was considered, but was ruled out by the clinical findings, and MG was confirmed by the positive tensilon test, electrophysiological findings and positive acetylcholine receptor binding antibodies. On further evaluation, a CT chest scan showed a left anterior mediastinal mass and bilateral lymphadenopathy. Post surgical diagnosis confirmed the thymoma and sarcoidosis in the lymph nodes. Conclusion When two or more diseases of undetermined origin are found together, several interesting questions are raised. It is important to first confirm the diagnoses individually. Immunologic mechanisms triggering the occurrence of these diagnoses together, are difficult to address. Although the coexistence of thymoma, MG and sarcoidosis may be coincidental, it is noteworthy to report this case because of the multiple interesting features observed as well as the rarity of occurrence.

FOXL2 Is an Essential Activator of SF-1-Induced Transcriptional Regulation of Anti-Müllerian Hormone in Human Granulosa Cells.

Directory of Open Access Journals (Sweden)

Full Text Available Anti-Müllerian hormone (AMH is required for proper sexual differentiation by regulating the regression of the Müllerian ducts in males. Recent studies indicate that AMH could be an important factor for maintaining the ovarian reserve. However, the mechanisms of AMH regulation in the ovary are largely unknown. Here, we provide evidence that AMH is an ovarian target gene of steroidogenic factor-1 (SF-1, an orphan nuclear receptor required for proper follicle development. FOXL2 is an evolutionally conserved transcription factor, and its mutations cause blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES, wherein affected females display eyelid defects and premature ovarian failure (POF. Notably, we found that functional FOXL2 is essential for SF-1-induced AMH regulation, via protein-protein interactions between FOXL2 and SF-1. A BPES-inducing mutant of FOXL2 (290-291delCA was unable to interact with SF-1 and failed to mediate the association between SF-1 and the AMH promoter. Therefore, this study identified a novel regulatory circuit for ovarian AMH production; specifically, through the coordinated interplay between FOXL2 and SF-1 that could control ovarian follicle development.

2018-03-29

Dagfinn Aarksog first described faciodigitogenital syndrome in 1970. Its inheritance is X linked and autosomally recessive. Currently, the diagnosis of Aarskog-Scott syndrome (ASS) is based on clinical dysmorphologic findings and can be supported by genetic examination. This report describes 3 brothers already diagnosed with ASS who were referred for examination of oral and maxillofacial malformations associated with ASS. They presented classic features of ASS, such as digital and genital (shawl scrotum) anomalies. More specifically, in terms of orbitopalpebral malformations, they showed marked ptosis with hypertelorism and antimongoloid palpebral fissure that gave them the characteristic facies. Concerning their oral and maxillofacial malformations, they had dental and skeletal major discrepancies and some dental agenesia. ASS is a rare X-linked syndrome composed of numerous morphologic facial, digital, and genital anomalies. The diagnosis is established genetically with the FGD1 mutation but there is no phenotypic and genotypic correlation with FGD1 mutations. Concerning maxillofacial malformations, maxillary and mandibular hypoplasia with jaw discrepancies can be found, as can teeth anomalies. It seems that these anomalies are widely underestimated.

2018-01-01

In May 2015, we noticed an increase in carbapenem-resistant Acinetobacter baumannii (CRAB) infections in the Medical Intensive Care Unit (MICU). To investigate this, we studied the extent of environmental contamination and subsequent onward clonal transmission of CRAB. We conducted a one-day point prevalence screening (PPS) of the patients and environment in the MICU. We screened patients using endotracheal tube aspirates and swabs from nares, axillae, groin, rectum, wounds, and exit sites of drains. We collected environmental samples from patients' rooms and environment outside the patients' rooms. CRAB isolates from the PPS and clinical samples over the subsequent one month were studied for genetic relatedness by whole genome sequencing (WGS). We collected 34 samples from seven patients and 244 samples from the environment. On the day of PPS, we identified 8 CRAB carriers: 3 who screened positive and 5 previously known clinical infections. We detected environmental contamination in nearly two-thirds of the rooms housing patients with CRAB. WGS demonstrated genetic clustering of isolates within rooms but not across rooms. We analysed 4 CRAB isolates from clinical samples following the PPS. One genetically-related CRAB was identified in the respiratory sample of a patient with nosocomial pneumonia, who was admitted to the MICU five days after the PPS. The extensive environmental colonization of CRAB by patients highlights the importance of environmental hygiene. The transmission dynamics of CRAB needs further investigation.

Nasal obstruction is considered to be a potential etiological factor in sleep-disordered breathing. However, a significant correlation between nasal measurements and obstructive sleep apnea has not been demonstrated so far. The aim of this study was to investigate the relationships between nasal resistance, nasal volumes and selected sleep parameters using nasal measurements performed in both seated and supine positions. We also investigated whether snoring patients in our clinical sample showed increased positional or decongestive nasal mucosal changes. Forty-one snoring men on a waiting list for correction of nasal obstruction underwent polysomnography, anterior rhinomanometry and acoustic rhinometry. Nineteen non-snoring control subjects were also recruited. Nasal measurements were performed in a seated position, after lying down in a supine position and, after decongestion of nasal mucosa, in a seated position again. In the overall patient group, nasal volume at a distance 2-4 cm from the nares in the supine position correlated inversely with apnea-hypopnea index (AHI) (r = -0.32, p patients, total nasal resistance measured in a supine position correlated with AHI (r = 0.50, p position and sleep parameters. Postural or decongestive changes in nasal measurements were not increased in snoring patients compared with control subjects. The relationship found between nasal measurements and sleep parameters suggests that nasal obstruction does augment airway collapse.

Full Text Available The nares represent an important bacterial reservoir for endogenous infections. This study aimed to assess the prevalence of nasal colonization by different important pathogens, the associated antimicrobial susceptibility and risk factors. We performed a prospective cohort study among 1878 nonhospitalized volunteers recruited from the general population in Germany. Participants provided nasal swabs at three time points (each separated by 4–6 months. Staphylococcus aureus, Enterobacteriaceae and important nonfermenters were cultured and subjected to susceptibility testing. Factors potentially influencing bacterial colonization patterns were assessed. The overall prevalence of S. aureus, Enterobacteriaceae and nonfermenters was 41.0, 33.4 and 3.7%, respectively. Thirteen participants (0.7% were colonized with methicillin-resistant S. aureus. Enterobacteriaceae were mostly (>99% susceptible against ciprofloxacin and carbapenems (100%. Extended-spectrum β-lactamase–producing isolates were not detected among Klebsiella oxytoca, Klebsiella pneumoniae and Escherichia coli. Several lifestyle- and health-related factors (e.g. household size, travel, livestock density of the residential area or occupational livestock contact, atopic dermatitis, antidepressant or anti-infective drugs were associated with colonization by different microorganisms. This study unexpectedly demonstrated high nasal colonization rates with Enterobacteriaceae in the German general population, but rates of antibiotic resistance were low. Methicillin-resistant S. aureus carriage was rare but highly associated with occupational livestock contact.

How animals navigate the constantly moving and visually uniform pelagic realm, often along straight paths between distant sites, is an enduring mystery. The mechanisms enabling pelagic navigation in cartilaginous fishes are particularly understudied. We used shoreward navigation by leopard sharks (Triakis semifasciata) as a model system to test whether olfaction contributes to pelagic navigation. Leopard sharks were captured alongshore, transported 9 km offshore, released, and acoustically tracked for approximately 4 h each until the transmitter released. Eleven sharks were rendered anosmic (nares occluded with cotton wool soaked in petroleum jelly); fifteen were sham controls. Mean swimming depth was 28.7 m. On average, tracks of control sharks ended 62.6% closer to shore, following relatively straight paths that were significantly directed over spatial scales exceeding 1600 m. In contrast, tracks of anosmic sharks ended 37.2% closer to shore, following significantly more tortuous paths that approximated correlated random walks. These results held after swimming paths were adjusted for current drift. This is the first study to demonstrate experimentally that olfaction contributes to pelagic navigation in sharks, likely mediated by chemical gradients as has been hypothesized for birds. Given the similarities between the fluid three-dimensional chemical atmosphere and ocean, further research comparing swimming and flying animals may lead to a unifying paradigm explaining their extraordinary navigational abilities.

Full Text Available Background: Methicillin resistant Staphylococcus aureus (MRSA is one of the most important pathogen in hospitals. Healthcare personnel are the main source of nosocomial infections and identification and control of MRSA carriers can reduce incidence of infections. The aim of this study was to determine the prevalence of MRSA and their antibiotic susceptibility profile among healthcare workers in Gorgan.Materials and Method: 333 healthcare workers were participated in this cross-sectional study in 2009. Samples were taken with sterile cotton swabs from both anterior nares and hands. Swabs were plated immediately on to the mannitol salt agar. Suspected colonies were confirmed as S. aureus by Gram staining, catalase, coagulase and DNase tests. Minimum inhibition concentration by micro dilution broth method was used to determine methicillin resistant strains. Antimicrobial susceptibility to other antibiotics was performed according to NCCLS guidelines by disc diffusion method.Result: Frequency of S.aureus and MRSA carriers among healthcare workers was 24% and 3% respectively. The highest rate of S. aureus and MRSA carriers were observed in operating room staff. Resistance to penicillin was seen in 97.5% of isolates and all strains were sensitive to vancomycin.Conclusions: Frequency of S. aureus and MRSA in healthcare workers was median and rather low respectively. Continual monitoring and control of carriers can reduce distribution of this organism and their infections

We assessed O(2) gas deprivation potential of bedding that had actually been used by 26 infants diagnosed with sudden unexpected infant death using FiCO(2) time course of baby mannequin model. All cases were the same ones in our poster paper (I). Mathematically, time-FiCO(2) (t) graphs were given as FiCO(2) (t)=C(1-e(Dt)). Here, "C" approximates the maximum FiCO(2) value, while "D" is the velocity to reach maximum FiCO(2). FiO(2) in a potential space around the mannequin's nares was estimated using a formula: FiO(2)=0.21-FiCO(2)/RQ. RQ is the respiratory quotient, and the normal human value is 0.8. The graph pattern of FiO(2) is roughly the inverse of the FiCO(2) time course. Four cases showed the bottom of estimated FiO(2) to be more than 15%, 15 were 15-6%, and the other seven were 6% or less. Considering the minimal tissue stores of O(2), changes in FiO(2) may be affected by both CO(2) production and gas movement around the infant's face. Especially, the latter seven cases may suggest the participation of the role not only of CO(2) accumulation but also of the decrease of O(2) around the face.

Pharyngeal phase is a central hub of swallowing in which food bolus pass through from the oral cavity to the esophageal. Proper understanding of the muscular activities in the pharyngeal phase is useful for assessing swallowing function and the occurrence of dysphagia in humans. In this study, high-density (HD) surface electromyography (sEMG) was used to study the muscular activities in the pharyngeal phase during swallowing tasks involving three healthy male subjects. The root mean square (RMS) of the HD sEMG data was computed by using a series of segmented windows as myoelectrical energy. And the RMS of each window covering all channels (16×5) formed a matrix. During the pharyngeal phase of swallowing, three of the matrixes were chosen and normalized to obtain the HD energy maps and the statistical parameter. The maps across different viscosity levels offered the energy distribution which showed the muscular activities of the left and right sides of the front neck muscles. In addition, the normalized average RMS (NARE) across different viscosity levels revealed a left-right significant correlation (r=0.868±0.629, pstronger correlation when swallowing water. This pilot study suggests that HD sEMG would be a potential tool to evaluate muscular activities in pharyngeal phase during normal swallowing. Also, it might provide useful information for dysphagia diagnosis.

Full Text Available En la última década, algunos cirujanos plásticos hemos procurado crear técnicas de mamoplastia de reducción con cicatrices menores tratando de no alterar la orfología y la fisiología de la mama. Algunas de ellas dejan resultados poco agradables y ptosis inmediatas en pacientes con grandes hipertrofias mamarias o gigantomastias que necesitan de cicatriz en T invertida para eliminar el exceso de tejido presente en estos casos, con una cicatriz en surco inframamario que muchas veces sobrepasa lateralmente la línea axilar anterior y llega, medialmente, hasta la región esternal. Con el objetivo de obtener cicatrices en el surco inframamario que no sean mayores de 10 cm. de longitud, presentamos una nueva técnica de mamoplastia de reducción realizada en 52 pacientes, con edades comprendidas entre los 16 y los 70 años, que presentaban grandes hipertrofias mamarias o gigantomastias. Esta técnica, con la cual hemos logrado extirpar hasta 1.500 gr. de tejido mamario, tiene una marcación que permite desde el inicio resecar el exceso de tejido del polo inferior de la mama con una cicatriz no mayor de 10 cm. de longitud en el surco inframamario, debido a que las prolongaciones medial y lateral de la mama se tratan con liposucción superficial. Un colgajo glánduloadiposo de pedículo superior ayuda a elevar la mama, a llenar el polo superior de la misma y a aumentar su proyección.In the last decade, Plastic Surgery has created reduction mammoplasty techniques with less scarring trying not to modify the normal morphology and physiology of the breast.

Full Text Available BACKGROUND AND AIMS: Snake bite is an important cause of mortality and morbidity in certain parts of Sri Lanka. This study was designed to determine the offending snakes, neurological manifestations, disease course, and outcome in neurotoxic envenomation. METHODS AND MATERIAL: Fifty six consecutive patients admitted with neurological manifestations following snake bite were studied prospectively. Data were obtained regarding the offending snakes, neurological symptoms, time taken for onset of symptoms, neurological signs, and time taken for recovery. RESULTS: The offending snake was Russell′s viper in 27(48.2%, common and Sri Lankan krait in 19(33.9%, cobra in 3(5.4%, and unidentified in 7(12.5%. Ptosis was the commonest neurological manifestation seen in 48(85.7% followed by ophthalmoplegia (75%, limb weakness (26.8%, respiratory failure (17.9%, palatal weakness (10.7%, neck muscle weakness (7.1%, and delayed sensory neuropathy (1.8%. Neurological symptoms were experienced usually within 6 hours after the bite. Following administration of antivenom, the signs of recovery became evident within a few hours to several days. The duration for complete recovery ranged from four hours to two weeks. CONCLUSIONS: Complete recovery of neuromuscular weakness was observed in all patients except for one who died with intracerebral haemorrhage shortly after admission.

Purpose: To evaluate ophthalmologic outcomes and toxicity of intensity modulated radiation therapy (IMRT) in patients with meningiomas causing visual deficits. Methods and Materials: A prospective observational study with formal ophthalmologic and clinical assessment of 30 consecutive cases of meningioma affecting vision treated with IMRT from 2007 to 2011. Prescriptions were 50.4 Gy to mean target dose in 28 daily fractions. The median follow-up time was 28 months. Twenty-six meningiomas affected the anterior visual pathway (including 3 optic nerve sheath meningiomas); 4 were posterior to the chiasm. Results: Vision improved objectively in 12 patients (40%). Improvements were in visual field (5/16 patients), color vision (4/9 patients), acuity (1/15 patients), extraocular movements (3/11 patients), ptosis (1/5 patients), and proptosis (2/6 patients). No predictors of clinical response were found. Two patients had minor reductions in tumor dimensions on magnetic resonance imaging, 1 patient had radiological progression, and the other patients were stable. One patient experienced grade 2 keratitis, 1 patient had a minor visual field loss, and 5 patients had grade 1 dry eye. Conclusion: IMRT is an effective method for treating meningiomas causing ophthalmologic deficits, and toxicity is minimal. Thorough ophthalmologic assessment is important because clinical responses often occur in the absence of radiological change.

The present authors encountered a rare traumatic case of Weber's syndrome in which computerized tomography (CT) revealed a hematoma localized in the tegmentum of the midbrain. This 49-year-old male was admitted because of a disturbed consciousness level caused by a hit on the right frontal area in a traffic accident. A neurological examination on admission disclosed Weber's syndrome: a dilatation of the right pupil, no reaction to direct or indirect light stimuli, ptosis of the right eyelid, lateral deviation of the right eyeball, and left hemiparesis with increased deep tendon reflexes and Babinski's sign. CT revealed a high-density area localized in the tegmentum of the midbrain, but interpeduncular and quadrigeminal cisterns were patent. After admission, his motor function and level of consciousness have showed improvement with medical treatment, but his right oculomotor palsy is unchanged. CT performed 7 days after admission showed a low-density area in place of the absorbed hematoma. In this case, we cannot explain the mechanism of the primary brain-stem injury. However, there are four possible mechanisms: nerve avulsion, neurovascular friction, localized contusion, and shear strain injury. Careful consideration of the anatomical relationship shows that it is likely that the lesion was a contusional hemorrhage caused by impact on the tentorial edge. (author)

In the past decade, the popularity of minimally invasive procedures for facial rejuvenation has increased. To describe a new specialized suture, and its associated technique, used to elevate sagging tissues of the face and neck. A detailed description of the technique and the results obtained in 20 patients in whom we have used this novel approach. Attention was given to appropriate patient selection. The primary focus was on the correction of the jowl, jawline, and neck subunits. It involves the percutaneous introduction of a novel 3-0 polypropylene suture that has 10 absorbable hollow cones along its axis that are equally interspersed with knots. Once the absorbable cones are resorbed into the surrounding tissues, the non-absorbable suture component can be removed without compromising the aesthetic outcome. All patients demonstrated improvement in these areas, with minimal complications. One patient required resuspension using the open technique. (Excessive ptotic tissue was later excised for an optimal cosmetic result.) The suture and technique described in this article provide a major contribution to the correction of ptosis of facial tissues. When done in conjunction with other procedures, such as neck and jowl microliposuction, this technique has proven to be a useful addition to facial rejuvenation.

Involvement of the Cerebral Monoamine Neurotransmitters System in Antidepressant-Like Effects of a Chinese Herbal Decoction, Baihe Dihuang Tang, in Mice Model

Full Text Available Baihe Dihuang Tang (BDT is a renowned Chinese herbal formula which is commonly used for treating patients with mental instability, absentmindedness, insomnia, deficient dysphoria, and other psychological diseases. These major symptoms closely associated with the depressive disorders. BDT was widely popular use for treating emotion-thought disorders for many years in China. In the present study, the antidepressant-like effect of BDT in mice was investigated by using the forced swim test (FST and the tail suspension test (TST. The underlying mechanism was explored by determining the effect of BDT on the level of cerebral monoamine neurotransmitters. BDT (9 and 18 g/kg, p.o. for 14 days administration significantly reduced the immobility time in both the FST and the TST without changing locomotion in the open field-test (OFT. Moreover, BDT treatment at the dose of 18 g/kg inhibited reserpine-induced ptosis. Meanwhile, BDT enhanced 5-HT and NA levels in mouse cerebrum as well as decreased the ratio of 5-HT compared to its metabolite, 5-HIAA, (turnover, 5-HIAA/5-HT after TST. The results demonstrated that the antidepressant-like effect of BDT is mediated, at least partially, via the central monoaminergic neurotransmitter system.

The root part of Paeonia lactiflora Pall. (Ranunculaceae), known as peony, is often used in Chinese herbal formulae for the treatment of depression-like disorders. Previous studies in our laboratory have shown that an ethanol extract of peony produced antidepressive effects in mouse models of depression. It is well known that peony contains glycosides such as paeoniflorin and albiflorin, yet it remains unclear whether the total glycosides of peony (TGP) are effective. The present study aims to evaluate the antidepressant-like effects of TGP. The antidepressant-like effects of TGP was determined by using animal models of depression including forced swim and tail suspension tests. The acting mechanism was explored by determining the effect of TGP on the activities of monoamine oxidases. Intragastric administration of TGP at 80 and 160 mg/kg for seven days caused a significant reduction of immobility time in both forced swim and tail suspension tests, yet TGP did not stimulate locomotor activity in the open-field test. In addition, TGP treatment antagonized reserpine-induced ptosis and inhibited the activities of monoamine oxidases in mouse cerebrum. These results suggest that the antidepressive effects of TGP are mediated, at least in part, by the inhibition of monoamine oxidases.

Dopamine beta-hydroxylase deficiency

Senard Jean-Michel

2006-03-01

Full Text Available Abstract Dopamine beta-hydroxylase (DβH deficiency is a very rare form of primary autonomic failure characterized by a complete absence of noradrenaline and adrenaline in plasma together with increased dopamine plasma levels. The prevalence of DβH deficiency is unknown. Only a limited number of cases with this disease have been reported. DβH deficiency is mainly characterized by cardiovascular disorders and severe orthostatic hypotension. First symptoms often start during a complicated perinatal period with hypotension, muscle hypotonia, hypothermia and hypoglycemia. Children with DβH deficiency exhibit reduced ability to exercise because of blood pressure inadaptation with exertion and syncope. Symptoms usually worsen progressively during late adolescence and early adulthood with severe orthostatic hypotension, eyelid ptosis, nasal stuffiness and sexual disorders. Limitation in standing tolerance, limited ability to exercise and traumatic morbidity related to falls and syncope may represent later evolution. The syndrome is caused by heterogeneous molecular alterations of the DBH gene and is inherited in an autosomal recessive manner. Restoration of plasma noradrenaline to the normal range can be achieved by therapy with the synthetic precursor of noradrenaline, L-threo-dihydroxyphenylserine (DOPS. Oral administration of 100 to 500 mg DOPS, twice or three times daily, increases blood pressure and reverses the orthostatic intolerance.

In this study, we report our experience with botulinum toxin in the treatment of facial region disorders. METHODS: Patients who had been followed in the Botulinum Toxin Outpatient Clinic of the Neurology Department were retrospectively evaluated. Two preparations of botulinum toxin type A (BT-A were used. The efficacy of BT-A injections was rated according to the improvement in symptoms as follows: marked - 75-100% improvement, good - 50-74%, moderate - 25-49%, and insufficient - less than 25% symptom relief. RESULTS: One hundred eighty-two patients (73 male, 109 female with various facial region disorders were included. The efficacy rates for patients who had very good and good improvement were high in the treatment of blepharospasm, hemifacial spasm, facial synkinesis, and Meige syndrome and moderate for oromandibular dystonia and hypersalivation. Ptosis was the most common side effect. CONCLUSION: According to our results, botulinum toxin was very effective treatment for blepharospasm, Meige syndrome, hemifacial spasm and facial synkinesis, whereas it demonstrated good efficacy in oromandibular dystonia and hypersalivation

We studied ventilation in kangaroos from mesic and arid environments, the eastern grey kangaroo (Macropus giganteus) and the red kangaroo (Macropus rufus), respectively, within the range of ambient temperatures (T(a)) from -5 degrees to 45 degrees C. At thermoneutral temperatures (Ta=25 degrees C), there were no differences between the species in respiratory frequency, tidal volume, total ventilation, or oxygen extraction. The ventilatory patterns of the kangaroos were markedly different from those predicted from the allometric equation derived for placentals. The kangaroos had low respiratory frequencies and higher tidal volumes, even when adjustment was made for their lower basal metabolism. At Ta>25 degrees C, ventilation was increased in the kangaroos to facilitate respiratory water loss, with percent oxygen extraction being markedly lowered. Ventilation was via the nares; the mouth was closed. Differences in ventilation between the two species occurred at higher temperatures, and at 45 degrees C were associated with differences in respiratory evaporative heat loss, with that of M. giganteus being higher. Panting in kangaroos occurred as a graded increase in respiratory frequency, during which tidal volume was lowered. When panting, the desert red kangaroo had larger tidal volumes and lower respiratory frequencies at equivalent T(a) than the eastern grey kangaroo, which generally inhabits mesic forests. The inference made from this pattern is that the red kangaroo has the potential to increase respiratory evaporative heat loss to a greater level.

Initially four different methods of measuring total cation exchange capacity were compared. There were two chemical methods (ammonium saturation with displacement into seawater, and barium saturation followed by replacement with magnesium) and two radiochemical methods (sodium-22 and caesium-134 saturation). The barium-magnesium and sodium-22 methods were then applied to sediment samples from Core D10164Pound1K from the Nares Fracture Valley, and Core D10554Pound11K from the eastern flank of the Great Meteor Rise. The material at site 10164 is a pelagic clay whereas at site 10554 it is carbonate ooze. The total cation exchange capacities (T.C.E.C.) of samples from the two sites are similar when measured by the sodium-22 method, the mean for Core 10164 was 21.7 meq/100g and 24.4 meq/100g for Core 10554. However for Core 10554 the barium-magnesium method gives a mean of 42.8 meq/100g. The difference in T.C.E.C. measured by the two methods appears to be due to the high calcite content of core 10554 sediment. Measured exchange capacities are lower than in coastal sediments. In deep sea sediments organic matter either makes a very small contribution to the T.C.E.C. (core 10164) or actually blocks exchange sites (Core 10554). Amorphous oxides of iron and manganese contribute between 20 and 50% of the T.C.E.C. (author)

Overuse of antibiotics has led to the development of antibiotic-resistant strains of Staphylococcus aureus, which are occurring more frequently within the community. We sought to determine whether long-term antibiotic therapy for acne alter the carriage rate and antibiotic resistance profiles of S aureus. This was a prospective, cross-sectional, quasiexperimental study. Samples of anterior nares were obtained from dermatology patients given a diagnosis of acne vulgaris (n = 263) who were treated with antibiotics (n = 142) or who were not treated with antibiotics (n = 121). Specimens were tested for the presence of S aureus by growth on mannitol salt agar and then isolated on 5% sheep blood agar. Identification was confirmed based on colonial morphology, Gram stain, catalase, and coagulase testing. Antibiotic susceptibility testing was performed using the VITEK 2 system (bioMerieux, Marcy-l'Étoile, France). The S aureus carriage rate was significantly lower in patients with acne treated with antibiotics (6.3%) compared with those not treated with antibiotics (15.7%; P = .016). The percentage of S aureus isolates resistant to 1 or more antibiotics did not significantly differ between the 2 groups (P = .434). Cross-sectional study, patient compliance, and effects of prior acne treatments are limitations. Treatment of patients with acne using antibiotics decreases the S aureus carriage rate but does not significantly alter the antibiotic resistance rates.

Ice bridges and ridges in the Maxwell-EB sea ice rheology

Directory of Open Access Journals (Sweden)

V. Dansereau

2017-09-01

Full Text Available This paper presents a first implementation of a new rheological model for sea ice on geophysical scales. This continuum model, called Maxwell elasto-brittle (Maxwell-EB, is based on a Maxwell constitutive law, a progressive damage mechanism that is coupled to both the elastic modulus and apparent viscosity of the ice cover and a Mohr–Coulomb damage criterion that allows for pure (uniaxial and biaxial tensile strength. The model is tested on the basis of its capability to reproduce the complex mechanical and dynamical behaviour of sea ice drifting through a narrow passage. Idealized as well as realistic simulations of the flow of ice through Nares Strait are presented. These demonstrate that the model reproduces the formation of stable ice bridges as well as the stoppage of the flow, a phenomenon occurring within numerous channels of the Arctic. In agreement with observations, the model captures the propagation of damage along narrow arch-like kinematic features, the discontinuities in the velocity field across these features dividing the ice cover into floes, the strong spatial localization of the thickest, ridged ice, the presence of landfast ice in bays and fjords and the opening of polynyas downstream of the strait. The model represents various dynamical behaviours linked to an overall weakening of the ice cover and to the shorter lifespan of ice bridges, with implications in terms of increased ice export through narrow outflow pathways of the Arctic.

To describe the clinical, endoscopic, and serologic features of an outbreak of besnoitiosis in 2 donkey operations in northeastern Pennsylvania and to report the outcome of attempted treatment of 1 naturally infected individual. Observational study. 29 donkeys (Equus asinus) in northeastern Pennsylvania. Donkeys were examined for lesions suggestive of besnoitiosis in an outbreak investigation. Information was collected regarding the history and signalment of animals on each premises. Rhinolaryngoscopy was performed to identify nasopharyngeal and laryngeal lesions. Serum samples were collected for immunofluorescent antibody testing and immunoblotting for Besnoitia spp. Skin biopsy samples were obtained from 8 animals with lesions suggestive of besnoitiosis for histologic examination. Quantitative real-time PCR assay for Besnoitia spp was performed on tissue samples from 5 animals. Besnoitiosis was confirmed in 6 of the 8 suspected cases. The most common lesion site was the nares, followed by the skin and sclera. Donkeys with clinical signs of disease had higher serum antibody titers and tested positive for a greater number of immunoblot bands than did donkeys without clinical signs of disease. All animals evaluated by PCR assay tested positive. Putative risk factors for disease included age and sex. Ponazuril was not effective at treating besnoitiosis in a naturally infected donkey. Knowledge of clinical and serologic features of besnoitiosis in donkeys will assist clinicians in the diagnosis and prevention of this disease in donkey populations. Besnoitiosis may be an emerging disease of donkeys in the United States.

North America-Greenland-Eurasian relative motions: implications for circum-arctic tectonic reconstructions

Energy Technology Data Exchange (ETDEWEB)

Rowley, D.B.; Lottes, A.L.; Ziegler, A.M.

1985-02-01

The Mesozoic-Cenozoic tectonic evolution of the Circum-Arctic region is based on constraints imposed by (1) relative motion histories of the three major plates (North America, Greenland, and Eurasia) and a number of smaller pieces, and (2) distribution and age of sutures, accretionary prisms, volcanic arcs, fold-thrust belts, stretched continental crust, strike-slip faults, and ocean floor. The authors conclude that: (1) North America and Eurasia remained relatively fixed to each other until the latest Cretaceous-Paleocene opening of the Labrador Sea-Baffin Bay and Greenland-Norwegian and Eurasian basins (earlier convergence between North America and Eurasia in the Bering Sea region shown on many reconstructions are artifacts of incorrect plate reconstructions); (2) the North Slope-Seward-Chukotka block has constituted an isthmus connection between North America and northeast Asia since at least the middle Paleozoic and did not rotate away from the Canadian Arctic; (3) the Canada basin opened behind a clockwise-rotating Alpha Cordillera-Mendeleyev ridge arc during the Early to middle Cretaceous and consumed older, Paleozoic(.) Makarov basin ocean floor (the Chukchi cap is a detached continental fragment derived from the Beaufort Sea; the North Slope Arctic margin is a left-lateral transform fault associated with the opening of the Canada basin); and (4) the Nares Strait fault has a net relative displacement of approximately 25 km, but actual motion between Greenland and northern Ellesmere was about 250 km of strongly transpressive motion that resulted in the Eurekan and Svalbardian orogenies.

People with rare hypertrichosis syndromes became crowd-drawing money-making phenomena in many 19th century sideshow acts. These individuals have been referred to as dog-men, hair-men, and werewolves. In 1993, Baumister et al. described congenital hypertrichosis lanuginose or Ambras syndrome: a distinct form of congenital hypertrichosis characterized by excessive hair growth over the body and face associated with facial and occasional dental anomalies. Much is not known about this syndrome since fewer than 50 cases have been documented worldwide. In this case report, a nine year old girl presented with excessive hair growth throughout her body that was denser along her midline. Furthermore, her face displayed the typical dysmorphic features characteristic of Ambras syndrome: a round tip nose, thickened nasal cartilage, antiverted nares, prominent philtrum with deep groove, and a trapezoid mouth. Oral examination revealed normal oral mucosa with completely missing and unerupted decidious and permanent teeth. Panoramic radiographs confirmed unerupted deciduous teeth. Previous case reports have mentioned the presence of occasional dental anomalies such as retarded first and second dentition and absence of some teeth. However, this is the first reported case of Ambras syndrome presenting with complete anodontia. Prior cytogenetic studies performed on persons with Ambras syndrome have implicated a balanced pericentric inversion of chromosome 8. However, it is likely that dental anomalies are likely a result of a different genetic rearrangement. Further studies are needed to explore the cause of this rare phenotype of Ambras syndrome with complete unerupted dentition.

To compare the failure rates between Jet continuous positive airway pressure device (J-CPAP-variable flow) and Bubble continuous positive airway device (B-CPAP) in preterm infants with respiratory distress. Preterm newborns CPAP (a variable flow device) or B-CPAP (continuous flow device). A standardized protocol was followed for titration, weaning and removal of CPAP. Pressure was monitored close to the nares in both the devices every 6 hours and settings were adjusted to provide desired CPAP. The primary outcome was CPAP failure rate within 72 h of life. Secondary outcomes were CPAP failure within 7 days of life, need for surfactant post-randomization, time to CPAP failure, duration of CPAP and complications of prematurity. An intention to treat analysis was done. One-hundred seventy neonates were randomized, 80 to J-CPAP and 90 to B-CPAP. CPAP failure rates within 72 h were similar in infants who received J-CPAP and in those who received B-CPAP (29 versus 21%; relative risks 1.4 (0.8 to 2.3), P=0.25). Mean (95% confidence intervals) time to CPAP failure was 59 h (54 to 64) in the Jet CPAP group in comparison with 65 h (62 to 68) in the Bubble CPAP group (log rank P=0.19). All other secondary outcomes were similar between the two groups. In preterm infants with respiratory distress starting within 6 h of life, CPAP failure rates were similar with Jet CPAP and Bubble CPAP.

Endonasal procedures may be necessary during management of craniofacial trauma. When a skull base fracture is present, these procedures carry a high risk of violating the cranial vault and causing brain injury or central nervous system infection. A 52-year-old bicyclist was hit by an automobile at high speed. He sustained extensive maxillofacial fractures, including frontal and sphenoid sinus fractures (Fig. 1). He presented to the emergency room with brisk nasopharyngeal hemorrhage, and was intubated for airway protection. He underwent emergent stabilization of his nasal epistaxis by placement of a Foley catheter in his left nare and tamponade with the Foley balloon. A six-vessel angiogram showed no evidence of arterial dissection or laceration. Imaging revealed inadvertent insertion of the Foley catheter and deployment of the balloon in the frontal lobe (Fig. 2). The balloon was subsequently deflated and the Foley catheter removed. The patient underwent bifrontal craniotomy for dural repair of CSF leak. He also had placement of a ventriculoperitoneal shunt for development of post-traumatic hydrocephalus. Although the hospital course was a prolonged one, he did make a good neurological recovery. The authors review the literature involving violation of the intracranial compartment with medical devices in the settings of craniofacial trauma. Caution should be exercised while performing any endonasal procedure in the settings of trauma where disruption of the anterior cranial base is possible. Copyright © 2013 Surgical Associates Ltd.

Providing alternative training modalities may improve trainees' ability to perform septoplasty. Three-dimensional printing has been shown to be a powerful tool in surgical training. The objectives of this study were to explain the development of our 3-dimensional (3D) printed septoplasty training model, to assess its face and content validity, and to present evidence supporting its ability to distinguish between levels of surgical proficiency. Imaging data of a patient with a nasal septal deviation was selected for printing. Printing materials reproducing the mechanical properties of human tissues were selected based on literature review and prototype testing. Eight expert rhinologists, 6 senior residents, and 6 junior residents performed endoscopic septoplasties on the model and completed a postsimulation survey. Performance metrics in quality (final product analysis), efficiency (time), and safety (eg, perforation length, nares damage) were recorded and analyzed in a study-blind manner. The model was judged to be anatomically correct and the steps performed realistic, with scores of 4.05 ± 0.82 and 4.2 ± 1, respectively, on a 5-point Likert scale. Ninety-two percent of residents desired the simulator to be integrated into their teaching curriculum. There was a significant difference (p simulator training models for septoplasty. Our model incorporates 2 different materials mixed into the 3 relevant consistencies necessary to simulate septoplasty. Our findings provide evidence supporting the validity of the model. © 2016 ARS-AAOA, LLC.

Full Text Available La mastopexia con implantes de silicona, es uno de los procedimientos más frecuentes en la práctica diaria en Cirugía Plástica. Sin embargo, la pobre calidad de la cobertura de las mamas, relacionada con piel estriada, escaso tejido subcutáneo y pérdida del parénquima mamario secundarios a la lactancia prolongada y a la pérdida masiva de peso, son causa del incremento progresivo de resultados insatisfactorios a medio y largo plazo que han sido evaluados, analizados y discutidos por los especialistas. Los resultados insatisfactorios más frecuentes en mastopexia con implantes en posición retromuscular son: doble contorno mamario, asimetrías y desplazamiento de los implantes. Los objetivos del presente estudio son: describir el nuevo método triplanar como alternativa útil para lograr mejores resultados en pacientes con mala calidad de cobertura y analizar los resultados obtenidos con el mismo. Realizamos un estudio observacional, descriptivo, prospectivo, en un grupo de 268 pacientes con diagnóstico de ptosis mamaria con hipotrofia y mala calidad de cobertura por piel estriada, escaso tejido celular subcutáneo y pérdida del parénquima mamario, secundarios a lactancia prolongada y pérdida masiva de peso, entre otros, a las que se les practicó mamoplastia de aumento con implantes de silicona mediante la aplicación del método triplanar descrito por la autora, entre enero del 2004 y enero del 2013 en el Hospital de Bocagrande de Cartagena, Colombia.

Full Text Available Botulinum toxin A (BTA inhibits presynaptic release of acetylcholine at the neuromuscular junction and has reportedly been successful in the treatment of spastic disorders.To evaluate the effect of botulinum toxin on cerebral palsied children with spastic or mixed type of the disease, especially those patiens having spasticity as a cardinal symptom without joint contracture, we designed the following study. Ninety-one cases (55 of referred patients to pediatic Neurology outpatient clinics of children’s Medical Center were given BTA injections in affected muscles of the lower limb. They were reevaluating 3 to 5 weeks and 3 months later for type of walking and range of affected joints’ movement. The study showed a clinically significant gait improvement in 71.2% of patients (P<0.0005 and also an overall increased range of motion in affected limbs after BTA injection (P<0.04. Side effects occurred only in two cases as transient generalized weakness, gent recurvatum and ptosis. Drug effectiveness was time-limited, lasting abot 3 months in all patients ( a golden time for rehabilitation therapists to improve the patients’ condition. Overall, BTA has improved both the type of walking as well as the range of joints motion in our patients. So its’ administration is suggested in cerebral palsied children if the spasticity is a major and disabling sign

Incidence and diagnosis of anosognosia for hemiparesis revisited

Baier, B; Karnath, H

2005-01-01

Background: In previous studies, the incidence of anosognosia for hemiparesis has varied between 17% and 58% in samples of brain damaged patients with hemiparesis. Objective: To determine whether this wide variation might be explained by the different criteria used for diagnosing anosognosia. Methods: 128 acute stroke patients with hemiparesis or hemiplegia were tested for anosognosia for hemiparesis using the anosognosia scale of Bisiach et al. Results: 94% of the patients who were rated as having "mild anosognosia"—that is, they did not acknowledge their hemiparesis spontaneously following a general question about their complaints—suffered from, and mentioned, other neurological deficits such as dysarthria, ptosis, or headache. However, they immediately acknowledged their paresis when they were asked about the strength of their limbs. Their other deficits clearly had a greater impact. These patients had significantly milder paresis than those who denied their disorder even when asked directly about their limbs. Conclusions: Patients who do not mention their paresis spontaneously but do so when questioned about it directly should not be diagnosed having "anosognosia." If this more conservative cut off criterion is applied to the data of the present as well as previous studies, a frequency of between 10% and 18% for anosognosia for hemiparesis is obtained in unselected samples of acute hemiparetic stroke patients. The incidence thus seems smaller than previously assumed. PMID:15716526

SUMOylation of the Forkhead transcription factor FOXL2 promotes its stabilization/activation through transient recruitment to PML bodies.

Directory of Open Access Journals (Sweden)

Adrien Georges

Full Text Available BACKGROUND: FOXL2 is a transcription factor essential for ovarian development and maintenance. It is mutated in the genetic condition called Blepharophimosis Ptosis Epicantus inversus Syndrome (BPES and in cases of isolated premature ovarian failure. We and others have previously shown that FOXL2 undergoes several post-translational modifications. METHODS AND PRINCIPAL FINDINGS: Here, using cells in culture, we show that interference with FOXL2 SUMOylation leads to a robust inhibition of its transactivation ability, which correlates with a decreased stability. Interestingly, FOXL2 SUMOylation promotes its transient recruitment to subnuclear structures that we demonstrate to be PML (Promyelocytic Leukemia Nuclear Bodies. Since PML bodies are known to be sites where post-translational modifications of nuclear factors take place, we used tandem mass spectrometry to identify new post-translational modifications of FOXL2. Specifically, we detected four phosphorylated, one sulfated and three acetylated sites. CONCLUSIONS: By analogy with other transcription factors, we propose that PML Nuclear Bodies might transiently recruit FOXL2 to the vicinity of locally concentrated enzymes that could be involved in the post-translational maturation of FOXL2. FOXL2 acetylation, sulfation, phosphorylation as well as other modifications yet to be discovered might alter the transactivation capacity of FOXL2 and/or its stability, thus modulating its global intracellular activity.

The purpose of this study was to investigate the hitherto undescribed effects of botulinum toxin A injected into the lacrimal gland in patients with functional epiphora. A prospective non-comparative interventional case series study was designed to include patients with functional epiphora who presented to the Oculoplastic unit at the Wolverhampton and Midland Counties Eye Infirmary. Botulinum toxin A (2.5-5 units) was injected into the palpebral lobe of the lacrimal gland on the worst affected side via a transconjunctival approach under topical anaesthesia. Patients underwent a Schirmer test and provided a subjective evaluation of their epiphora symptoms, indoors and outdoors, at baseline and at 1, 4 and 13 weeks after injection. The mean score for symptoms indoors and outdoors was calculated. Fourteen patients agreed to take part in the study. Subjective epiphora scores improved in 8 out of the 11 patients (72.7%) who completed 13 weeks of follow-up. Schirmer test results showed objective reduction in tearing from baseline but did not strongly correlate with the subjective epiphora scores. Transient mild ptosis and diplopia were experienced by two patients. The results from this small pilot study are encouraging, although larger, controlled trials are needed to assess the optimal dose of BTX-A, its long-term efficacy and safety, and the role of multiple injections.

Skull Base Langerhans Cell Histiocytosis with Diabetes Insipidus and Panhypopituitarism- A Rare Clinical Entity

Case Report A 16 year old male presented with diminished vision, bilateral ptosis, left sided lateral rectus palsy, hypoesthesia of trigeminal nerve with nasal obstruction for last 5 months. There was polypoidal, bleeding mass in both nasal cavities. Contrast enhanced CT Scan showed a large homogenous mass arising from sphenoid extending into cavernous sinus and the suprasellar region. Endoscopic nasal biopsy revealed abundant Langerhans cell histiocytes, macrophages, neutrophils. Chemotherapy and radiotherapy were administered. But within 2 months the patient presented with Cushingoid features and further diminution of vision. Detailed work-up revealed Hypogonadotrophic hypogonadism and diabetes insipidus. Debulking of the tumour was done and left optic nerve decompression was done. PET scan was performed and showed large, well defined mass with increased FDG uptake in the skull base with suprasellar extension, reaching upto petrous temporal bone and causing bony erosion of ethmoid and sphenoid sinuses. Patient was then advised adjuvant chemotherapy.   Discussion Langerhans cell histiocytosis is a rare group of disorders characterised by abnormal clonal proliferation and accumulation of abnormal dendritic cells. Involvement of base of skull is even rarer. Though diabetes insipidus has been reported in Langerhans cell histiocytosis involving pituitary, panhypopituitarism is rare. These combinations of extensive Langerhans cell histiocytosis of base skull with clinical features of Diabetes insipidus and panhypopituitarism makes this case a rare clinical entity.

Introduction: Mosaic trisomy 8 or "Warkany's Syndrome" is a chromosomopathy with an estimated prevalance of 1:25,000 to 1:50,000, whose clinical presentation has a wide phenotypic variability. Case Description: Patient aged 14 years old with antecedents of global retardation of development, moderate cognitive deficit and hypothyroidism of possible congenital origin. Clinical Findings: Physical examination revealed palpebral ptosis, small corneas and corectopia, hypoplasia of the upper maxilla and prognathism, dental crowding, high-arched palate, anomalies of the extremities such as digitalization of the thumbs, clinodactyly and bilateral shortening of the fifth finger, shortening of the right femur, columnar deviation and linear brown blotches that followed Blaschko's lines. Cerebral nuclear magnetic resonance revealed type 1 Chiari's malformation and ventriculomegaly. Although the karyotype was normal in peripheral blood (46,XY), based on the finding of cutaneous mosaicism the lesions were biopsied and cytogenetic analysis demonstrated mosaic trisomy 8: mos 47,XY,+8[7]/46,XY[93]. Clinical Relevance: Trisomy 8 is clinically presented as a mosaic, universal cases being unfailingly lethal. In this particular case, cutaneous lesions identified the mosaic in tissue, although the karyotype was normal in peripheral blood. The cutaneous mosaicism represented by brown linear blotches which follow Blaschko's lines is a clinical finding that has not previously been described in Warkany's syndrome. PMID:27546932

A gene prenature ovarian failure associated with eyelid malformation maps to chromosomes 3q22-q23

Premature ovarian failure and XX gonadal dysgenesis leading to female infertility have been reported in association with an autosomal dominantly inherited malformation of the eyelids: blepharophimosis-ptosis-epicanthus inversus syndrome (BPES; MIM 110100). This association distinguishes BPES type I from BPES type II, in which affected females are fertile and the transmission occurs through both sexes. Recently, a gene responsible for BPES type II has been mapped to chromosome 3q22-q23, and the critical region for the gene location has been reduced to the interval between loci D3S1615 and D3S1316. Hitherto, however, no information regarding the localization of the gene for BPES type I, in which female ovarian failure is associated with eyelid malformation, has been available. We have studied two independent families affected with BPES type I, including a total of 12 affected individuals (6 infertile women) and 6 healthy relatives. The diagnostic criteria for the ophthalmological anomaly included (1) reduced horizontal diameter of palpebral fissures, (2) drooping of the upper eyelids, and (3) an abnormal skinfold running from the lower lids. Telecanthus and a flat nasal bridge were present in most cases. In both families the disease was transmitted only by the male, and no affected woman of childbearing age was fertile. 12 refs., 2 figs., 1 tab.

Anti-snake venom: use and adverse reaction in a snake bite study clinic in Bangladesh

Full Text Available Snakebites can present local or systemic envenomation, while neurotoxicity and respiratory paralysis are the main cause of death. The mainstay of management is anti-snake venom (ASV, which is highly effective, but liable to cause severe adverse reactions including anaphylaxis. The types of adverse reaction to polyvalent anti-snake venom have not been previously studied in Bangladesh. In this prospective observational study carried out between 1999 and 2001, in the Snake Bite Study Clinic of Chittagong Medical College Hospital, 35 neurotoxic-snake-bite patients who had received polyvalent anti-snake venom were included while the ones sensitized to different antitoxins and suffering from atopy were excluded. The common neurotoxic features were ptosis (100%, external ophthalmoplegia (94.2%, dysphagia (77.1%, dysphonia (68.5% and broken neck sign (80%. The percentage of anti-snake venom reaction cases was 88.57%; pyrogenic reaction was 80.64%; and anaphylaxis was 64.51%. The common features of anaphylaxis were urticaria (80%; vomiting and wheezing (40%; and angioedema (10%. The anti-snake venom reaction was treated mainly with adrenaline for anaphylaxis and paracetamol suppository in pyrogenic reactions. The average recovery time was 4.5 hours. Due to the danger of reactions the anti-snake venom should not be withheld from a snakebite victim when indicated and appropriate guidelines should be followed for its administration.

The orbital region is of vital importance to facial expression. Brow ptosis, besides having an impact on facial harmony, is a sign of aging. Various surgical techniques have been developed to increase the efficacy of brow-lift surgery. However, no consensus method exists for an objective measurement of the eyebrow position due to the curvature of the face. Therefore, this study aimed to establish a method for measuring the eyebrow position using computerized photogrammetry. For this study, 20 orbital regions of 10 volunteers were measured by direct anthropometry using a digital caliper and by indirect anthropometry (computerized photogrammetry) using standardized digital photographs. Lines, points, and distances were defined based on the position of the anthropometric landmarks endocanthion and exocanthion and then used to calculate the brow position index (BPI). Statistical analysis was performed using Student's t test with a significance level of 5 %. The BPI values obtained by computerized photogrammetric measurements did not differ significantly from those obtained by direct anthropometric measurements (p > 0.05). The mean BPI was 84.89 ± 10.30 for the computerized photogrammetric measurements and 85.27 ± 10.67 for the direct anthropometric measurements. The BPI defined in this study and obtained by computerized photogrammetry is a reproducible and efficient method for measuring the eyebrow position. This journal requires that authors assign a level of evidence to each article.

Objective To evaluate how malar fat pad (MFP) volumes vary with age, after controlling for gender and body mass index (BMI). Study Design A prospective case-control study evaluating volume of the MFP in women of two age groups. Methods Soft tissue dimensions were measured in eight subjects using magnetic resonance imaging. A multiplanar localizing sequence, followed in sagittal and coronal orientations using a turbo spin echo sequence, was performed to define the MFP. Volumetric calculations were then performed using a 3D image analysis application (Dextroscope, Volume Interactions, Republic of Singapore) to circumscribe areas, orient dimensions, and calculate volumes of the MFP. Results These data reveal no significant difference in the mean (standard deviation) right MFP (p = 0.50), left MFP (p = 0.41), or total MFP (p = 0.45) volumes when comparing the two age groups. In addition, these data indicate that there was no correlation between age and total MFP volume (Pearson correlation coefficient 0.27). Moreover, there was no correlation between age and the ratio of total volume/BMI (Pearson correlation coefficient -0.18). Conclusions Although the sample size of this study was small, these data indicate that ptosis of midfacial fat is more important than volume loss in midfacial aging. These data would suggest repositioning as the primary modality for craniofacial reconstruction.

Plant natriuretic peptides: Systemic regulators of plant homeostasis and defense that can affect cardiomyoblasts

KAUST Repository

Gehring, Christoph A.

2010-09-01

Immunologic evidence has suggested the presence of biologically active natriuretic peptide (NPs) hormones in plants because antiatrial NP antibodies affinity purify biologically active plant NPs (PNP). In the model plant, an Arabidopsis thaliana PNP (AtPNP-A) has been identified and characterized. AtPNP-A belongs to a novel class of molecules that share some similarity with the cell wall loosening expansins but do not contain the carbohydrate-binding wall anchor thus suggesting that PNPs and atrial natriuretic peptides are heterologs. AtPNP-A acts systemically, and this is consistent with its localization in the apoplastic extracellular space and the conductive tissue. Furthermore, AtPNP-A signals via the second messenger cyclic guanosine 3′,5′-monophosphate and modulates ion and water transport and homeostasis. It also plays a critical role in host defense against pathogens. AtPNP-A can be classified as novel paracrine plant hormone because it is secreted into the apoplastic space in response to stress and can enhance its own expression. Interestingly, purified recombinant PNP induces apo-ptosis in a dose-dependent manner and was most effective on cardiac myoblast cell lines. Because PNP is mimicking the effect of ANP in some instances, PNP may prove to provide useful leads for development of novel therapeutic NPs.

Full Text Available Introduction: The association of myasthenia gravis (MG with other autoimmune diseases including autoimmune thyroid disease (ATD is well recognised, although rare. The occurrence of both diseases can occur in two ways: either disease preceding the other, or concurrently. The presentation of MG in association with ATD can range from ocular to generalised disease. Case Summary: A 26-year-old Malay female with persistent hyperthyroidism secondary to Hashimoto’s thyroiditis in multinodular goitre was diagnosed with generalised MG after 2 years. She presented with right eye ptosis (ocular and difficulty in swallowing and chewing (bulbar. The diagnosis of MG was confirmed by fatigability testing, electromyography and the presence of AChR antibodies. Her symptoms showed improvement with pyridostigmine (Mestinon 60 mg 6-hourly. Her antithyroid drug was tapered down according to her thyroid function test. Throughout a year of follow-ups, her hyperthyroidism and fatigability symptoms improved with treatment. She was later counselled for total thyroidectomy and thymectomy. Conclusion: Myasthenia gravis and hyperthyroidism may present with similar symptoms such as dysphagia due to neuromuscular weakness or fatigue. When the diseases occur together, one of the diagnoses may be missed. Therefore, the occurrence of new symptoms in a patient with underlying ATD should should trigger the early identification of other autoimmune diseases by primary care doctors.

We report the rare case of a 74-year-old man with anti-Ma2-associated paraneoplastic neurologic syndrome (PNS), and review and analyze the clinical manifestations, diagnosis, and treatment of the disease. The patient presented with a 5-month history of muscle weakness, progressive body aches, and weakness and numbness in both lower extremities. Before his hospitalization, he had experienced cognitive function decline; ptosis, inward gaze, and vertical gaze palsy in the right eye; and occasional visual hallucinations. Brain and spinal cord magnetic resonance imaging (MRI) yielded normal results. Anti-Ma2 antibodies were detected in both serum and cerebrospinal fluid. A 4-hour electroencephalogram showed irregular sharp slow waves and δ waves in the temporal region. Electromyography showed peripheral nerve demyelination. Positron-emission tomography/computed tomography (PET-CT) examination revealed hypermetabolism in the lymph nodes of the whole body. Biopsy of the lymph nodes showed non-Hodgkin lymphoma. A clinical diagnosis of lymphoma and PNS was made. The patient was treated with intravenous dexamethasone (15 mg/day) for 3 days. We have presented a rare case of a PNS involving both the central and peripheral nervous systems. The clinical features of this case indicated anti-Ma2-associated encephalitis and chronic inflammatory demyelinating polyneuropathy. PET-CT played a critical role in enabling early diagnosis and prompt treatment in this case.

Adult mitochondrial DNA depletion syndrome with mild manifestations

Full Text Available Mitochondrial DNA depletion syndrome (MDS is usually a severe disorder of infancy or childhood, due to a reduced copy number of mtDNA molecules. MDS with only mild, non-specific clinical manifestations and onset in adulthood has not been reported. A 47-year-old Caucasian female with short stature and a history of migraine, endometriosis, Crohn’s disease, C-cell carcinoma of the thyroid gland, and a family history positive for mitochondrial disorder (2 sisters, aunt, niece, developed day-time sleepiness, exercise intolerance, and myalgias in the lower-limb muscles since age 46y. She slept 9-10 hours during the night and 2 hours after lunch daily. Clinical exam revealed sore neck muscles, bilateral ptosis, and reduced Achilles tendon reflexes exclusively. Blood tests revealed hyperlipidemia exclusively. Nerve conduction studies, needle electromyography, and cerebral and spinal magnetic resonance imaging were non-informative. Muscle biopsy revealed detached lobulated fibers with subsarcolemmal accentuation of the NADH and SDH staining. Real-time polymerase chain reaction revealed depletion of the mtDNA down to 9% of normal. MDS may be associated with a mild phenotype in adults and may not significantly progress during the first year after onset. In an adult with hypersomnia, severe tiredness, exercise intolerance, and a family history positive for mitochondrial disorder, a MDS should be considered.

To describe the motor pattern of cataplexy and to determine its phenomenological differences from pseudocataplexy in the differential diagnosis of episodic falls. We selected 30 video-recorded cataplexy and 21 pseudocataplexy attacks in 17 and 10 patients evaluated for suspected narcolepsy and with final diagnosis of narcolepsy type 1 and conversion disorder, respectively, together with self-reported attacks features, and asked expert neurologists to blindly evaluate the motor features of the attacks. Video documented and self-reported attack features of cataplexy and pseudocataplexy were contrasted. Video-recorded cataplexy can be positively differentiated from pseudocataplexy by the occurrence of facial hypotonia (ptosis, mouth opening, tongue protrusion) intermingled by jerks and grimaces abruptly interrupting laughter behavior (i.e. smile, facial expression) and postural control (head drops, trunk fall) under clear emotional trigger. Facial involvement is present in both partial and generalized cataplexy. Conversely, generalized pseudocataplexy is associated with persistence of deep tendon reflexes during the attack. Self-reported features confirmed the important role of positive emotions (laughter, telling a joke) in triggering the attacks, as well as the more frequent occurrence of partial body involvement in cataplexy compared with pseudocataplexy. Cataplexy is characterized by abrupt facial involvement during laughter behavior. Video recording of suspected cataplexy attacks allows the identification of positive clinical signs useful for diagnosis and, possibly in the future, for severity assessment.

The sedative effect induced by administering xylazine hydrochloride or detomidine hydrochloride with or without butorphanol tartrate to standing dairy cattle was compared in two groups of six adult, healthy Holstein cows. One group received xylazine (0.02 mg/kg i.v.) followed by xylazine (0.02 mg/kg) and butorphanol (0.05 mg/kg i.v.) 1 week later. Cows in Group B received detomidine (0.01 mg/kg i.v.) followed by detomidine (0.01 mg/kg i.v.) and butorphanol (0.05 mg/kg i.v.) 1 week later. Heart rate, respiratory rate, and arterial blood pressure were monitored and recorded before drugs were administered and every 10 minutes for 1 hour after drug administration. The degree of sedation was evaluated and graded. Cows in each treatment group had significant decreases in heart rate and respiratory rate after test drugs were given. Durations of sedation were 49.0 +/- 12.7 minutes (xylazine), 36.0 +/- 14.1 (xylazine with butorphanol), 47.0 +/- 8.1 minutes (detomidine), and 43.0 +/- 14.0 minutes (detomidine with butorphanol). Ptosis and salivation were observed in cows of all groups following drug administration. Slow horizontal nystagmus was observed from three cows following administration of detomidine and butorphanol. All cows remained standing while sedated. The degree of sedation seemed to be most profound in cows receiving detomidine and least profound in cows receiving xylazine.

Brain-computer interfaces (BCIs) might restore communication to people severely disabled by amyotrophic lateral sclerosis (ALS) or other disorders. We sought to: 1) define a protocol for determining whether a person with ALS can use a visual P300-based BCI; 2) determine what proportion of this population can use the BCI; and 3) identify factors affecting BCI performance. Twenty-five individuals with ALS completed an evaluation protocol using a standard 6 × 6 matrix and parameters selected by stepwise linear discrimination. With an 8-channel EEG montage, the subjects fell into two groups in BCI accuracy (chance accuracy 3%). Seventeen averaged 92 (± 3)% (range 71-100%), which is adequate for communication (G70 group). Eight averaged 12 (± 6)% (range 0-36%), inadequate for communication (L40 subject group). Performance did not correlate with disability: 11/17 (65%) of G70 subjects were severely disabled (i.e. ALSFRS-R < 5). All L40 subjects had visual impairments (e.g. nystagmus, diplopia, ptosis). P300 was larger and more anterior in G70 subjects. A 16-channel montage did not significantly improve accuracy. In conclusion, most people severely disabled by ALS could use a visual P300-based BCI for communication. In those who could not, visual impairment was the principal obstacle. For these individuals, auditory P300-based BCIs might be effective.

Isorhynchophylline (IRN), an oxindole alkaloid, has been identified as the main active ingredient responsible for the biological activities of Uncaria rhynchophylla (Miq) Miq ex Havil. (Rubiaceae). Previous studies in our laboratory have revealed that IRN possesses potent neuroprotective effects in different models of Alzheimer's disease. However, the antidepressant-like effects of IRN are remained unclear. The present study aims to evaluate the antidepressant-like effects of IRN. The antidepressant-like effects of IRN was determined by using animal models of depression including forced swimming and tail suspension tests. The acting mechanism was explored by determining the effect of IRN on the levels of monoamine neurotransmitters and the activities of monoamine oxidases. Intragastric administration of IRN at 10, 20 and 40 mg/kg for 7 days caused a significant reduction of immobility time in both forced swimming and tail suspension tests, while IRN did not stimulate locomotor activity in the open-field test. In addition, IRN treatment antagonized reserpine-induced ptosis and significantly enhanced the levels of monoamine neurotransmitters including norepinephrine (NE) and 5-hydroxytryptamine (5-HT), and the activity of monoamine oxidase A (MAO-A) in the hippocampus and frontal cortex of mice. These results suggest that the antidepressant-like effects of IRN are mediated, at least in part, by the inhibition of monoamine oxidases.

Myxedema Coma due to Hashimoto Thyroiditis: A Rare but Real Presentation of Failure to Thrive in Infancy.

Hashimoto thyroiditis (HT) is uncommon in infancy, and myxedema coma (MC) is even less common. While prior reports have documented these entities separately, to our knowledge, MC in combination with HT has not been reported before in this age group. A 10-month-old female presented with ptosis, lethargy, dysphagia, and failure to thrive (FTT). She developed hypotension, bradycardia, hypothermia, and apnea requiring intubation. Initial thyroid-stimulating hormone was 422 μIU/mL, and free thyroxine was < 0.5 ng/dL, despite the presence of a normal thyroid newborn screen (NBS). Of note, sepsis workup was unremarkable. With the diagnosis of MC, treatment with intravenous levothyroxine was initiated, although after hydrocortisone administration to avert the possibility of an adrenal crisis, despite a random cortisol of 16.4 μg/dL. Based on positive thyroid antibodies suggesting HT, autoimmune workup later revealed positive acetylcholinesterase antibodies consistent with a diagnosis of ocular myasthenia gravis. MC may be a cause of altered mental status in infancy and may simultaneously be associated with FTT on presentation. With the presence of a normal thyroid NBS, autoimmunity should be entertained as the etiology of profound hypothyroidism, as positive thyroid antibodies may prompt an exploration for coexisting diseases which may explain other presenting features. © 2018 S.

Turtle hatchlings orient display sea-ward oriented movements as soon as they emerge from the nest. Although most studies have emphasized the role of the visual information in this process, less attention has been paid to other sensory modalities. Here, we evaluated the nature of sensory cues used by turtle hatchlings of Chelonia agassizi to orient their movements towards the ocean. We recorded the time they took to crawl from the nest to the beach front (120m long) in control conditions and in visually, olfactory and magnetically deprived circumstances. Visually-deprived hatchlings displayed a high degree of disorientation. Olfactory deprivation and magnetic field distortion impaired, but not abolished, sea-ward oriented movements. With regard to the neuronal mapping experiments, visual deprivation reduced dramatically c-fos expression in the whole brain. Hatchlings with their nares blocked revealed neurons with c-fos expression above control levels principally in the c and d areas, while those subjected to magnetic field distortion had a wide spread activation of neurons throughout the brain predominantly in the dorsal ventricular ridge The present results support that Chelonia agassizi hatchlings use predominantly visual cues to orient their movements towards the sea. Olfactory and magnetic cues may also be use but their influence on hatchlings oriented motor behavior is not as clear as it is for vision. This conclusion is supported by the fact that in the absence of olfactory and magnetic cues, the brain turns on the expression of c- fos in neuronal groups that, in the intact hatchling, are not normally involved in accomplishing the task.

Comparisons of skull shape between closely related species can provide information on the role that phylogeny and function play in cranial evolution. We used 3D-anatomical landmarks in order to study the skull ontogeny of two closely related species, Lagenorhynchus obscurus and Lagenorhynchus australis, with a total sample of 52 skulls. We found shared trends between species, such as the relative compression of the neurocranium and the enlargement of the rostrum during ontogeny. However, these are common mammalian features, associated with prenatal brain development and sensory capsules. Moreover, we found a posterior displacement of the external nares and infraorbital foramina, and a strong development of the rostrum in an anteroposterior direction. Such trends are associated with the process of telescoping and have been observed in postnatal ontogeny of other odontocetes, suggesting a constraint in the pattern. Interspecific differences related to the deepness of facial region, robustness of the feeding apparatus and rostrum orientation may be related with the specific lifestyles of L. obscurus and L. australis. We also tested the presence of three different modules in the skull (basicranium, neurocranium, rostrum), all of which presented strong integration. Only the rostrum showed a different ontogenetic trajectory between species. Even though we detected directional asymmetry, changes in this feature along ontogeny were not detectable. Because asymmetry may be related to echolocation, our results suggest a functional importance of directional asymmetry from the beginning of postnatal life. J.

Equine methicillin-resistant Staphylococcus aureus (MRSA) carriage entails a risk of both equine and zoonotic transmission and infection. In Europe, CC398, the livestock-associated (LA-)MRSA is highly prevalent in horses and veterinary personnel at equine clinics. The extent of the MRSA reservoir created by healthy horses from the general population and associated health hazard for their daily caretakers is, however, unknown. This study aimed at screening healthy horse-caretaker couples from a broad range of home farms. At five equine gatherings, 166 couples were selected for MRSA screening in the anterior nares and participation in an epidemiologic survey. All MRSA isolates were subjected to genotyping and antimicrobial susceptibility testing. Only 4 humans (2.4%) and 2 of their horses (1.2%) tested MRSA positive. Within the 2 couples where both partners were positive, man and horse carried isolates belonging to identical, livestock-associated spa types (t011 and t2330) and demonstrating equal antimicrobial susceptibility patterns. For all LA-MRSA positive humans (n=3) and animals (n=2) regular (in)direct contact with the veterinary sector was reported. A significant association between the horses' carriage status and transportation to an event could not be demonstrated (P=1.00). In conclusion, outside equine clinics, the extent of the MRSA reservoir in horses and their caretakers was low. Travel to an equine gathering could not be withheld as a risk factor for equine MRSA carriage, whereas indications were found that contact with veterinary care may predispose both healthy horses and their handlers to carriage.

Full Text Available Abstract Background Brachycephalic dogs have unique upper respiratory anatomy with abnormal breathing patterns similar to those in humans with obstructive sleep apnea syndrome (OSAS. The objective of this study was to evaluate the correlation between anatomical components, clinical signs and several biomarkers, used to determine systemic inflammation and myocardial damage (C-reactive protein, CRP; Haptoglobin, Hp; cardiac troponin I, cTnI, in dogs with brachycephalic upper airway obstructive syndrome (BAOS. Results Fifty brachycephalic dogs were included in the study and the following information was studied: signalment, clinical signs, thoracic radiographs, blood work, ECG, components of BAOS, and CRP, Hp and cTnI levels. A high proportion of dogs with BAOS (88% had gastrointestinal signs. The prevalence of anatomic components of BAOS was: elongated soft palate (100%, stenotic nares (96%, everted laryngeal saccules (32% and tracheal hypoplasia (29.1%. Increased serum levels of biomarkers were found in a variable proportion of dogs: 14% (7/50 had values of CRP > 20 mg/L, 22.9% (11/48 had values of Hp > 3 g/L and 47.8% (22/46 had levels of cTnI > 0.05 ng/dl. Dogs with everted laryngeal saccules had more severe respiratory signs (p Conclusions According to the low percentage of patients with elevated levels of CRP and Hp, BAOS does not seem to cause an evident systemic inflammatory status. Some degree of myocardial damage may occur in dogs with BAOS that can be detected by cTnI concentration.

Increasing rate of daptomycin non-susceptible strains of Staphylococcus aureus in patients with atopic dermatitis

Directory of Open Access Journals (Sweden)

2017-12-01

Full Text Available Introduction : Daptomycin is a cyclic lipopeptide that is bactericidal against Staphylococcus aureus , including methicillin-resistant S. aureus (MRSA, vancomycin-intermediate S. aureus (VISA and vancomycin-resistant S. aureus (VRSA strains. Daptomycin exerts its antimicrobial effect by a calcium-dependent interaction with the cytoplasmic membrane resulting in depolarization, ion loss and rapid cell death. Unfortunately, loss of daptomycin susceptibility in S. aureus in the clinical setting has been noted. Aim : To evaluate the susceptibility profile to daptomycin among S. aureus strains isloted from patients with atopic dermatitis (AD. Another point was to correlate the results obtained by broth microdilution method and Etest, which is commonly applied in clinical setting. Material and methods : One hundred patients with the diagnosis of atopic dermatitis were microbiologically assessed for the carriage of S. aureus . Antimicrobial susceptibility tests were performed using broth-microdilution (BMD and Etests for daptomycin. Results : Staphylococcus aureus strains were isolated from the majority of our patients, either from the skin (73% or the anterior nares (75%. Six of the 100 nasal swabs (6% and 5 of the 100 skin swabs (5% were positive for methicillin-resistant Staphylococcus aureus (MRSA. A total of 81 of 148 (54.7% daptomycin non-susceptible isolates of S. aureus were identified by BMD. Only 19 of 81 were also classified as non-susceptible by Etest. Conclusions : Clinicians and microbiologists should be aware of the possibility of the emergence of daptomycin non-susceptibility (or increase in minimal inhibitory concentration during prolonged therapy and closely monitor the susceptibility of persisting isolates that might be recovered during therapy.

To protect both the surgeon and patient during procedures, hooded protection shields are used during joint arthroplasty procedures. Headache, malaise, and dizziness, consistent with increased carbon dioxide (CO 2 ) exposure, have been anecdotally reported by surgeons using hoods. We hypothesized that increased CO 2 concentrations were causing reported symptoms. Six healthy subjects (4 men) donned hooded protection, fan at the highest setting. Arm cycle ergometry at workloads of 12 and 25 watts (W) simulated workloads encountered during arthroplasty. Inspired O 2 and CO 2 concentrations at the nares were continuously measured at rest, 12 W, and 25 W. At each activity level, the fan was deactivated and the times for CO 2 to reach 0.5% and 1.0% were measured. At rest, inspired CO 2 was 0.14% ± 0.04%. Exercise had significant effect on CO 2 compared with rest (0.26% ± 0.08% at 12 W, P = .04; 0.31% ± 0.05% at 25 W, P = .003). Inspired CO 2 concentration increased rapidly with fan deactivation, with the time for CO 2 to increase to 0.5% and 1.0% after fan deactivation being rapid but variable (0.5%, 12 ± 9 seconds; 1%, 26 ± 15 seconds). Time for CO 2 to return below 0.5% after fan reactivation was 20 ± 37 seconds. During simulated joint arthroplasty, CO 2 remained within Occupational Safety and Health Administration (OSHA) standards with the fan at the highest setting. With fan deactivation, CO 2 concentration rapidly exceeds OSHA standards. Copyright © 2017 Elsevier Inc. All rights reserved.

Sensitivity analysis of a ship accident at a deep-ocean site in the northwest Atlantic

International Nuclear Information System (INIS)

Kaplan, M.F.

1985-04-01

This report presents the results of a sensitivity analysis for an HLW ship accident occurring in the Nares Abyssal Plain in the northwestern Atlantic. Waste form release rate, canister lifetime and sorption in the water column (partition coefficients) were varied. Also investigated were the relative importance of the dose from the food chain and from seaweed in the diet. Peak individual doses and integrated collective doses for populations were the units of comparison. In accordance with international guidelines on radiological protection, the comparisons of different options were carried out over ''all time''; the study uses a million-year time frame. Partition coefficients have the most pronounced effect on collective dose of the parameters studied. Variations in partition coefficients affect the shape of the collective dose curve over the entire time frame. Peak individual doses decrease markedly when the value for the sorption of americium is increased, but show no increase when less sorption is assumed. Waste form release rates and canister lifetimes affect collective doses only in periods prior to 20,000 years. Hence, comparisons of these options need not be carried out beyond 20,000 years. Waste from release rates below 10 -3 /yr (nominal value) affect individual doses in a linear manner, i.e., an order-of-magnitude reduction in release rate leads to an order-of-magnitude reduction in peak individual dose. Little reduction in peak individual doses is seen with canister lifetimes extended beyond the nominal 100 years. 32 refs., 14 figs., 16 tabs
