Malaria is one of the major public health challenges undermining development in the world. The aim of Malar Sat Project is to provide a malaria risks infection maps at global scale using Earth Observation data to support and prevent epidemic episodes.
The proposed service for creating malaria risk maps would be critically useful to improve the efficiency in insecticide programs, vaccine campaigns and the logistics epidemic treatment.
Different teams have already carried out studies in order to exploit the use of Earth Observation EO data with epidemiology purposes. In the case of malaria risk maps, it has been shown that meteorological data is not sufficient to fulfill this objective. In particular being able to map the malaria mosquito habitat would increase the accuracy of risk maps. The malaria mosquitoes mainly reproduce in new water puddles of very reduced dimensions about 1 meter wide.
There is no instrument that could detect such small patches of water unless there are many of them spread in an area of several hundreds of meters. Malar Sat aims at using the radar altimeter data from the EnviSat, RA-2, to try and build indicators of mosquitoes existence. This presentation will show the scientific objectives and principles of the Malar Sat project. Eosinophilic annular erythema EAE is an uncommon eosinophilic dermatosis.
Clinically it is characterized by recurrent episodes of annular or figurative plaques. The histopathological study shows a perivascular inflammatory infiltrate in the superficial and deep dermis, composed of lymphocytes and eosinophils.
It was originally described in children. We report an adult woman who presented with recurrent erythematous annular plaques on the trunk and extremities. A biopsy showed a mainly perivascular lymphocytic infiltrate with numerous eosinophils in the dermis. Laboratory examinations revealed subclinical hypothyroidism. The lesions resolved with topical corticosteroid spontaneously after 3 months.
Presentamos una mujer adulta con episodios recurrentes de placas anulares o figuradas en el tronco y extremidades. The "beauty arch: " a new aesthetic analysis for malar augmentation planning. Midface is a critical area for the aesthetics of the face.
Despite malar hypoplasia is often combined with a class III malocclusion, there are few studies focusing on the results of a combined approach of malar implants and Le Fort I. We describe a new aesthetic analysis, named "beauty arch" analysis, for the assessment of sagittal projection of the malar region. We took a reference group of 74 Italian women participating in a national beauty contest in on which we performed our analysis. We used the ideal values to elaborate the surgical treatment planning of a second group of 45 consecutive female patients affected by skeletal class III malocclusion.
Twenty-three patients undergo simultaneous Le Fort I osteotomy and malar implants. From the descriptive statistical comparison of the patients' values before and after orthognathic surgery and malar implants with the reference values, we observed how all parameters considered got closer to the ideal population.
We consider our beauty arch a useful help for surgeon in the treatment planning of patients with skeletal malocclusions and malar implants. Combined approach for facial contour restoration: treatment of malar and cheek areas during rhytidectomy.
One of the main objectives in facial lifting is to achieve an adequate facial contour, to enhance facial characteristics. Sometimes, facial areas are more or less accentuated, resulting in an unbalanced or inharmonious facial contour; this can be resolved in the context of a face lift. In the middle third of the face, two anatomical regions define the facial silhouette: the malar contour, with its bone support and superficial structures and, at the cheek level, intimately associated with the mastication system and the facial nerve, the buccal fat pad or Bichat fat pad.
The authors describe their experience since using the double approach to malar atrophy and buccal fat pad hypertrophy in patients with facial aging signs undergoing a face lift. All patients were offered a face lift with partial resection of the fat pad through facial incisions and a stronger malar projection using an inverse superficial musculoaponeurotic system flap.
The main complications observed regarding this surgical technique, in order of appearance, were light asymmetry, caused by a persistent hematoma or swelling; paresthesia of the buccal and zygomatic branches, which resolved spontaneously; and a light sinking of the cheek caused by excessive resection. One patient underwent correction with a fat injection. The superior superficial musculoaponeurotic system flap and buccal fat pad resection provided excellent aesthetic results for a more harmonic and proportioned facial contour during rhytidectomy.
Particularly in patients with round faces, the authors were able to obtain permanent malar symmetry and projection in addition to diminishing the cheek fullness.
A computer program allows the tenth- to twelfth-grade student to attempt to control a malaria epidemic. This simulation provides a context within which to study the biological, economic, social, political, and ecological aspects of a classic world health problem. Three-dimensional 3D changes in the midface following malar calcium hydroxyapatite CaHa injection have not been systematically analyzed.
A single surgeon injected CaHa in the supraperiosteal plane. All measurements were performed by a single examiner. Injection location was verified anatomically. Injections were performed in 16 fresh cadaver hemi-faces. Maximal increases in projection were centered on the malar injection site, with associated decreases in projection and volume in the infero-medial locations. Relative mean increases in volume of 3.
There was a relative decrease in the volume of the NLF of Injection of CaHa was associated with lateral movements of the NLF-NLC junction at the level of the nasal sill, philtral columns, and oral commissure, measuring 2. Anatomical dissection verified the location in the supraperiosteal space and within the middle malar fat pad. Following malar CaHa injection, 3D photographic analysis showed a measureable lifting effect with recruitment of ptotic tissue and lateral movement of the NLF-NLC junction in a cadaver model.
Reprints and permission: journals. Surgical complications such as lid retraction and ectropion from graft or flap scar contracture make reconstruction of skin defects in the malar and infraorbital regions challenging.
A new flap design, the reading man flap, was used to overcome these problems. The Limberg and bilobed flap were compared with the reading man flap. The reading man flap consists mainly of a superiorly based quadrangular flap and an inferiorly based triangular flap.
Malar and infraorbital circular skin defects measuring 14 x 14 to 40 x 40 mm were reconstructed with a reading man flap in 13 patients. The defects occurred after basal cell carcinoma in all patients. The Limberg flap, bilobed flap, and reading man flap were planned for same-sized defects on the abdominoplasty resection material. The results were compared in terms of total scar area, scar length, and total healthy skin area discarded.
When comparing the 3 flap designs, the reading man flap was the most suitable flap in terms of total scar area and length. The reading man flap can be used to reconstruct malar and infraorbital circular defects with good cosmetic results and without creating any tractional forces to the eyelids.
To study the surgical management of enophthalmos after severe malar maxillary complex fracture. The X-ray and CT examination were performed before operation to diagnose the orbital fracture and intraorbital tissue displacement.
The fractured orbital rim was repositioned intraoperatively, followed by implantation of shaped titanium mesh to rebuild the orbital floor. The Medpor was inserted above the titanium mesh to correct the enophthalmos. From Sept. The enophthalmos was corrected or improved obviously in all the patients.
The enophthalmos after severe malar -maxillary complex fracture can be corrected or obviously improved. Shaped titanium mesh can be used to rebuild the orbital floor with the Medpor to reconstruct the intraorbital tissue volume.
Effect of subdepressor clonidine on flushing reactions in rosacea. Change in malar thermal circulation index during provoked flushing reactions. The effects of clonidine hydrochloride, an agent effective in suppressing other types of flushing reactions, were investigated in patients with erythematotelangiectatic rosacea. Clonidine hydrochloride, 0. Mean arterial BP was not altered during clonidine treatment. Flushing reactions provoked with water at 60 degrees C, red wine, and chocolate were not suppressed during clonidine treatment.
Clonidine did lead to malar hypothermia. It may be that any treatment benefit obtained from the reduction in vascular reactivity by clonidine in rosacea is offset by the malar hypothermia. An analysis of malar fat volume in two age groups: implications for craniofacial surgery. 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.
In addition, these data indicate that there was no correlation between age and total MFP volume Pearson correlation coefficient 0. These data would suggest repositioning as the primary modality for craniofacial reconstruction. Meloplication of the malar fat pads by percutaneous cable-suture technique for midface rejuvenation: outcome study cases, 6 years' experience. The aging anterior midface is restored by reversing the contour undulations produced by sagging of the malar fat pad complex toward the nasolabial line.
The convex irregularities include the exposed bulges of the post-septal fat, the unveiled malar bag, and the prominent nasolabial fold. The depressed irregularities are represented by the cresent-shaped hollow at the lid-cheek junction, the accentuated nasojugal groove, and the deepening nasolabial line. Repositioning of the ptotic malar fat pad, among other elements of meloplasty, represents a key procedure. In this study, the malar fat pad has been defined as a fan-shaped structure by external anatomic landmarks that correlate closely to the findings in cadaveric dissections and clinical cases, confirmed by the findings of spiral computed tomographic scanning.
A simple but powerful adjustable and long-lasting percutaneous suture elevation technique was developed over the past 6 years by the senior author G. Through a dot incision within the nasolabial line, a permanent CV-3 Gore-Tex or clear Prolene suspension suture, looped through a Gore-Tex anchor graft, suspends the malar fat pad in a direction perpendicular to the nasolabial line.
A second suspension system is identically passed through another lower dot incision to broaden the repositioning vectors on the malar fat pad. Tension on each of the paired suture ends elevates the malar fat pad by 1 to 3 mm as measured from the nasolabial dot incisions. The sutures are fixed to the deep temporal fascia through a Gore-Tex tab, effectively stabilizing the soft-tissue repositioning.
This maneuver may be performed in younger patients who present with an isolated malar fat pad ptosis without excess facial skin. The procedure may also be incorporated into open rhytidectomies to address this recalcitrant area along with superficial musculoaponeurotic system tightening. A total of patients since The pathogenesis of melasma, a common, photo-induced hyperpigmentary disorder, is not clearly understood.
Significant factors linked to melasma are ultraviolet radiation exposure and genetic predisposition.

ERITEMA MALAR PDF
It is often seen in lupus erythematosus but is not pathognomonic - it is also seen in other diseases such as pellagra , dermatomyositis , and Bloom syndrome. While some literature has described the slapped-cheek rash of fifth disease as a malar rash, it differs slightly in that the nose is typically spared. The malar rash of lupus is red or purplish and mildly scaly. Characteristically, it has the shape of a butterfly and involves the bridge of the nose. Notably, the rash spares the nasolabial folds of the face, which contributes to its characteristic appearance.
