Unilateral cleft lip repair: an anatomical subunit approximation technique.

BACKGROUND
A technique of unilateral cleft lip repair is described. The repair draws from a variety of previously described repairs and adheres to a concept of anatomical subunits of the lip. Cases from within the spectrum of the deformity have been chosen from a series of 144 consecutive cases to demonstrate the applicability of the technique in all forms of unilateral cleft lip.


METHODS
Incisions cross the lip perpendicular to the cutaneous roll at the cleft side peak of Cupid's bow of the medial lip and at the base of the philtral column of the lateral lip. Above this level, incisions ascend the lip to allow for approximation along a line symmetrical with the non-cleft-side philtral column. Incisions then ascend superolaterally bordering the lip columellar crease to the point of closure in the nostril sill. A Rose-Thompson lengthening effect occurs just above the level of the cutaneous roll. If necessary, a small triangle positioned just above the cutaneous roll is often used. Any central vermilion deficiency is augmented by a laterally based triangular vermilion flap from the lateral lip element.


RESULTS
Since January of 2000, this technique has been used in 144 consecutive unilateral cleft lip repairs. The inferior triangle is small (average, 1.24 mm; range, 0 to 2 mm). The technique can be applied to all degrees of unilateral cleft lip.


CONCLUSIONS
A technique of unilateral cleft lip repair is described. The repair allows for a repair line that ascends the lip at the seams of anatomical subunits.
Hexagram-Converter-Based STATCOM for Voltage Support in Fixed-Speed Wind Turbine Generation Systems

This paper studies the effectiveness of reactive power compensation using a multilevel, hexagram-converter-based STATic COMpensator (STATCOM) with one-cycle control (OCC) for a wind farm with fixed-speed turbines, and the interaction with the power system network. Comparison is made with several common types of multilevel voltage source converters used for STATCOM applications. A new voltage control method based on OCC principles for hexagram-based STATCOMs is proposed and proven by a wind farm power system simulation showing the improvement of voltage variations caused by wind speed changes. The experimental results from tests of a small-scale hexagram converter prototype have verified the proposed converter and control method.
Web-Based Collaborative Care for Type 2 Diabetes

OBJECTIVE
To test Web-based care management of glycemic control using a shared electronic medical record with patients who have type 2 diabetes.


RESEARCH DESIGN AND METHODS
We conducted a trial of 83 adults with type 2 diabetes randomized to receive usual care plus Web-based care management or usual care alone between August 2002 and May 2004. All patients had GHb > or =7.0%, had Web access from home, and could use a computer with English language-based programs. Intervention patients received 12 months of Web-based care management. The Web-based program included patient access to electronic medical records, secure e-mail with providers, feedback on blood glucose readings, an educational Web site, and an interactive online diary for entering information about exercise, diet, and medication. The primary outcome was change in GHb.


RESULTS
GHb levels declined by 0.7% (95% CI 0.2-1.3) on average among intervention patients compared with usual-care patients. Systolic blood pressure, diastolic blood pressure, total cholesterol levels, and use of in-person health care services did not differ between the two groups.


CONCLUSIONS
Care management delivered through secure patient Web communications improved glycemic control in type 2 diabetes.
Balanced to Unbalanced Power Divider With Arbitrary Power Ratio

In this letter, Balanced to Unbalanced (BTU) Gysel type Power divider (PD) with arbitrary power ratio is proposed. The proposed power divider shows out-of-phase characteristic at two unbalanced ports. Standard 4 × 4 scattering matrix of BTU PD with arbitrary power ratio is obtained from mixed mode scattering matrix. The analysis of the four port network is done by converting it into a two port network while other ports are matched terminated. Considering realizable impedance range of 20 - 120 Ω for microstrip lines, the maximum theoretical power division ratio is 1:4.76. Measurements are performed on a fabricated prototype (power dividing ratio 1:2) to verify the analytical results.
A current and future state of art development of hybrid energy system using wind and PV-solar : A review

The wind and solar energy are omnipresent, freely available, and environmental friendly. The wind energy systems may not be technically viable at all sites because of low wind speeds and being more unpredictable than solar energy. The combined utilization of these renewable energy sources are therefore becoming increasingly attractive and are being widely used as alternative of oil-produced energy. Economic aspects of these renewable energy technologies are sufficiently promising to include them for rising power generation capability in developing countries. A renewable hybrid energy system consists of two or more energy sources, a power conditioning equipment, a controller and an optional energy storage system. These hybrid energy systems are becoming popular in remote area power generation applications due to advancements in renewable energy technologies and substantial rise in prices of petroleum products. Research and development efforts in solar, wind, and other renewable energy technologies are required to continue for, improving their performance, establishing techniques for accurately predicting their output and reliably integrating them with other conventional generating sources. The aim of this paper is to review the current state of the design, operation and control requirement of the stand-alone PV solar–wind hybrid energy systems with conventional backup source i.e. diesel or grid. This Paper also highlights the future developments, which have the potential to increase the economic attractiveness of such systems and their acceptance by the user.

The Cubli: A cube that can jump up and balance

This paper introduces the Cubli, a 15×15×15 cm cube that can jump up and balance on a corner. Momentum wheels mounted on three faces of the cube (Fig. 1) rotate at high angular velocities and then brake suddenly, causing the Cubli to jump up. Once the Cubli has almost reached the corner stand-up position, controlled motor torques are applied to make it balance on its corner. This paper tracks the development of the Cubli's one dimensional prototype at ETH Zurich and presents preliminary results.
Recent Applications of Conformal Geometric Algebra

We discuss a new covariant approach to geometry, called conformal geometric algebra, concentrating particularly on applications to projective geometry and new hybrid geometries. In addition, a new method of working, which can achieve similar results, but using only one extra dimension instead of two, is also discussed.
Getting the basic rights - the role of water, sanitation and hygiene in maternal and reproductive health: a conceptual framework.

OBJECTIVE
To explore linkages between water, sanitation and hygiene (WASH) and maternal and perinatal health via a conceptual approach and a scoping review.


METHODS
We developed a conceptual framework iteratively, amalgamating three literature-based lenses. We then searched literature and identified risk factors potentially linked to maternal and perinatal health. We conducted a systematic scoping review for all chemical and biological WASH risk factors identified using text and MeSH terms, limiting results to systematic reviews or meta-analyses. The remaining 10 complex behavioural associations were not reviewed systematically.


RESULTS
The main ways poor WASH could lead to adverse outcomes are via two non-exclusive categories: 1. 'In-water' associations: (a) Inorganic contaminants, and (b) 'water-system' related infections, (c) 'water-based' infections, and (d) 'water borne' infections. 2. 'Behaviour' associations: (e) Behaviours leading to water-washed infections, (f) Water-related insect-vector infections, and (g-i) Behaviours leading to non-infectious diseases/conditions. We added a gender inequality and a life course lens to the above framework to identify whether WASH affected health of mothers in particular, and acted beyond the immediate effects. This framework led us to identifying 77 risk mechanisms (67 chemical or biological factors and 10 complex behavioural factors) linking WASH to maternal and perinatal health outcomes.


CONCLUSION
WASH affects the risk of adverse maternal and perinatal health outcomes; these exposures are multiple and overlapping and may be distant from the immediate health outcome. Much of the evidence is weak, based on observational studies and anecdotal evidence, with relatively few systematic reviews. New systematic reviews are required to assess the quality of existing evidence more rigorously, and primary research is required to investigate the magnitude of effects of particular WASH exposures on specific maternal and perinatal outcomes. Whilst major gaps exist, the evidence strongly suggests that poor WASH influences maternal and reproductive health outcomes to the extent that it should be considered in global and national strategies.
Presentation of burn injuries and their management outcome.

OBJECTIVE
To study the causes of burns and presentation of burn patients to POF Hospital and their overall management outcome.


METHODS
A cross sectional study of 111 burn patients presenting primarily to and admitted in Pakistan Ordinance Factory (POF) Hospital from December 2004 to August 2005 were included in the study. Patients of any age, any degree of burns and both sexes were included. Patients presenting after more than one week post burn or patients referred from other hospitals were excluded. A detailed history and examination was done before treatment was started. For statistical analysis, patients were divided into different age groups. The place of acquiring burns, the causes and mechanisms of burns and overall management outcome was studied and results expressed as means and percentages.


RESULTS
Mean age of patients was 18.96 years, 37.8% of the patients were children less than 10 years of age (Group 1), 39.6% were males more than 10 years of age (Group II), and 22.5% were females more than 10 years of age (Group III). Overall, 55% of the patients were males and 45% were females. Mean total body surface area (TBSA) burnt was 11-20%. In group-I patients, the place of burns was their home. The burns occurred at home in 31.8% of Group II patients, and 96% of Group III patients. The place of burns was workplace in 61.3% of Group II patients, and only 4% of Group III patients. The mechanism of burn was scalding in 73.8% of Group I, flame burns in 40.9% of Group II patients and 72% of Group III patients. 25% of Group II patients got electrical burn. The overall mortality was 29.7%.


CONCLUSION
The cause of burns was scalding at home in the majority of children less than ten years of age (Group I). Similarly the majority of group-II patients got burns at workplace in the form of either flame burns or electric burns. Many of the females more than ten years of age (Group III) got flame burns at home (suicidal, homicidal or accidental).
Effect of Child Development Centre model early stimulation among at risk babies--a randomized controlled trial.

OBJECTIVE
To study the effectiveness of Child Development Centre (CDC) model early stimulation therapy done in the first year of postnatal life, in improving the developmental outcome of at-risk neonates at one and two years of age.


DESIGN
Randomized controlled trial.


SETTING AND SUBJECTS
The study participants included a consecutive sample of 800 babies discharged alive from the level II nursery of Medical College, Thiruvananthapuram.


INTERVENTION
The control group received routine postnatal check-up as per hospital practice. Intervention group in addition received CDC model early stimulation therapy (home-based).


RESULTS
The intervention group of babies had a statistically significant higher score for mental developmental index (MDI) and psychomotor developmental index (PDI) at one and two years of age. After adjusting all significant risk factors for development, the babies who had intervention had significantly higher Bayley scores, 5.8 units at one year and 2.8 units at two year, as compared to control babies.


CONCLUSION
Early stimulation therapy was effective at one year. The beneficial effect also persisted at two years, without any additional interventions in the second year.
Efficient Verification of Concurrent Programs Over TSO Memory Model

We address the problem of efficient verification of multi-threaded programs running over Total Store Order (TSO) memory model. It has been shown that even with finite data domain programs, the complexity of control state reachability under TSO is non-primitive recursive. In this paper, we first present a bounded-buffer verification approach wherein a bound on the size of buffers is placed; verification is performed incrementally by increasing the size of the buffer with each iteration of the verification procedure until the said bound is reached. For programs operating on finite data domains, we also demonstrate the existence of a buffer bound k such that if the program is safe under that bound, then it is also safe for unbounded buffers. We have implemented this technique in a tool ProofTraPar. Our results against memorax [2], a state-of-the-art sound and complete verifier for TSO memory model, have been encouraging.
Endoscopic Surgery for Omohyoid Muscle Syndrome.

BACKGROUND
Omohyoid muscle syndrome (OMS) (not omohyoid syndrome) is a rare clinical condition that has a characteristic feature of a protruding lateral neck mass during swallowing. The use of endoscopic surgery on the neck is now pretty well established for thyroid and parathyroid glands. Patients with OMS usually undergo simple surgical transection of the omohyoid muscle. The procedure leaves operative scars on the neck, and most patients worry about the cosmetic problems. We report here the first use of an endoscopic procedure instead of traditional surgery for treatment of OMS.


MATERIALS AND METHODS
We present a rare case of a 26-year-old Chinese man who noted a protruding mass involving the right side of his neck during the past 10 years. OMS was diagnosed. Laparoscopic simple transection of the omohyoid muscle by an ultrasonically activated scalpel was performed.


RESULTS
After laparoscopic transection of the omohyoid muscle, the neck mass completely disappeared during swallowing, and there were no operative scars on the neck.


CONCLUSIONS
To our knowledge, this is the first report of laparoscopy for treatment of OMS. We believe that the laparoscopic procedure is made acceptable for this unusual disease because of the cosmetic result.
Monitoring the Internet for emerging psychoactive substances available to Australia.

INTRODUCTION AND AIMS
Novel psychoactive substances are increasingly available, both in traditional storefronts and via the Internet. While some use of such substances has been captured in Australian consumer surveys and wastewater analyses, there is little information about the products that are available to Australia via the Internet.


DESIGN AND METHODS
Systematic monthly Internet monitoring for emerging psychoactive substances was conducted between July 2011 and July 2012. Webstores identified through searches were examined to determine if they sold stimulant or psychedelic emerging psychoactive substances to Australia. Internet search numbers for these products were examined over time using commercial tools.


RESULTS
In 12 months, 43 unique webstores were identified selling to Australia, averaging two new webstores per month; however, two-fifths had closed within six months. Over 200 unique chemically unspecified products sold by purported effect (e.g. 'charge') were identified over 12 months, averaging 10 new products per month. Almost half of these products had disappeared from the market within six months. Eighty-six unique chemically specified products (e.g. methylenedioxypyrovalerone) were identified over 12 months, averaging four new novel substances per month. Once released, these products typically remained available, with almost 90% still available for purchase over a 6-month period. Almost 40 000 searches for these products emanated from Australia per month.


DISCUSSION AND CONCLUSION
This market is fast paced as retailers strive to beat both regulatory processes and competitors. Ongoing attention to these markets, incorporating surveillance of both Internet and traditional storefronts, is crucial as several of the substances identified have demonstrated potential for health and neurological harm.
A novel approach to design an antenna aperture tuning circuit

In this work, a new approach to design an antenna aperture tuning circuit for mobile phone antennas is proposed. Currently in the industry, the design of such a tuning circuit is done by using antenna S-parameter measurements. This method gives limited insight into the antenna performance parameters, specifically radiation power, which is a key performance parameter for an antenna. This paper presents a new approach to design an antenna tuning circuit, which gives additional in-depth knowledge on the performance improvement of the tuned antenna system. The proposed method uses non-linear 3-Dimensional Electro-Magnetic simulations of a mobile phone antenna structure which is co-simulated with antenna tuning circuit elements to realise an antenna tuning system. The effect of antenna tuning elements on the antenna parameters can be visualized in addition to simulating the antenna radiation patterns and the Total Radiated Power (TRP). Measurement and simulation results, of a fabricated prototype antenna, are presented and a close relation is found.

Definition, etiology, prevention and treatment of peri-implantitis – a review

Peri-implant inflammations represent serious diseases after dental implant treatment, which affect both the surrounding hard and soft tissue. Due to prevalence rates up to 56%, peri-implantitis can lead to the loss of the implant without multilateral prevention and therapy concepts. Specific continuous check-ups with evaluation and elimination of risk factors (e.g. smoking, systemic diseases and periodontitis) are effective precautions. In addition to aspects of osseointegration, type and structure of the implant surface are of importance. For the treatment of peri-implant disease various conservative and surgical approaches are available. Mucositis and moderate forms of peri-implantitis can obviously be treated effectively using conservative methods. These include the utilization of different manual ablations, laser-supported systems as well as photodynamic therapy, which may be extended by local or systemic antibiotics. It is possible to regain osseointegration. In cases with advanced peri-implantitis surgical therapies are more effective than conservative approaches. Depending on the configuration of the defects, resective surgery can be carried out for elimination of peri-implant lesions, whereas regenerative therapies may be applicable for defect filling. The cumulative interceptive supportive therapy (CIST) protocol serves as guidance for the treatment of the peri-implantitis. The aim of this review is to provide an overview about current data and to give advices regarding diagnosis, prevention and treatment of peri-implant disease for practitioners.
The Promise of Edge Computing

The success of the Internet of Things and rich cloud services have helped create the need for edge computing, in which data processing occurs in part at the network edge, rather than completely in the cloud. Edge computing could address concerns such as latency, mobile devices' limited battery life, bandwidth costs, security, and privacy.
A deep learning approach to the classification of sub-decimetre resolution aerial images

Spatial-contextual features play a vital role in the classification of very high resolution aerial images characterized by sub-decimetre resolution. However, manually extracting relevant contextual features is difficult and time-consuming in the analysis of sub-decimetre resolution images, where the objects of interest are significantly larger than the pixel size. Deep learning methods allow us to replace hand-crafted features by automatically learning contextual features from the image. In this paper, we investigate the use of convolutional neural networks (CNN) for the classification of urban areas using high resolution airborne images. We also analyse the sensitivity of network hyperparameters providing an interpretation of their effect on the extraction of spatial-contextual features. Experimental results show the effectiveness of CNN in learning discriminative contextual features leading to accurate classified maps and outperforming traditional classification methods based on the extraction of textural features.
Melatonin does not influence sleep deprivation electroencephalogram recordings in children

The electroencephalogram (EEG) is an essential diagnostic tool in children with epilepsy. The recording of a sleep EEG can increase the yield of EEG recordings in certain epileptic syndromes. The primary aim of this study was to assess the influence of melatonin on EEG recording (quality, EEG characteristics) and to assess its efficacy to induce sleep. Children with epilepsy or non-epileptic neurological patients requiring sleep deprivation EEG studies were enrolled into this prospective study at a tertiary University Hospital study. Sequential recording of sleep deprivation EEGs both with and without prior administration of melatonin was performed. A total of 50 patients (27 with epilepsy, 23 non-epileptic neurological patients) were included in this study (median age 9.5 years; range 1–18 years; male 28). The quality and EEG characteristics (abnormal findings, depth of sleep) were not affected by the use of melatonin. In total, 92 of 100 EEGs were successfully performed without significant differences between the two groups (six failures with melatonin, two failures without melatonin; p = 0.289). Conclusions We conclude that melatonin does not alter the quality of sleep EEG studies in children with epilepsy or suspected epilepsy. Melatonin does not increase the rate of successfully performed EEG studies in sleep-deprived children.
