Correlation-Assisted Pixel Array for Direct Time of Flight.

Time of flight is promising technology in machine vision and sensing, with an emerging need for low power consumption, a high image resolution, and reliable operation in high ambient light conditions. Therefore, we propose a novel direct time-of-flight pixel using the single-photon avalanche diode (SPAD) sensor, with an in-pixel averaging method to suppress ambient light and detect the laser pulse arrival time. The system utilizes two orthogonal sinusoidal signals applied to the pixel as inputs, which are synchronized with a pulsed laser source.

The first survey of the Saudi Acute Myocardial Infarction Registry Program: Main results and long-term outcomes (STARS-1 Program).

Background: Prior acute coronary syndrome (ACS) registries in Saudi Arabia might not have accurately described the true demographics and cardiac care of patients with ACS. We aimed to evaluate the clinical characteristics, management, and outcomes of a representative sample of patients with acute myocardial infarction (AMI) in Saudi Arabia.

Methods: We conducted a 1-month snap-shot, prospective, multi-center registry study in 50 hospitals from various health care sectors in Saudi Arabia.

PROTOZOA CAUSING FOOD POISONING.

Food poisoning also called foodbome illness, or illness caused by eating contaminated food is a term used to cover an unpleasant range of illnesses. Food poisoning symptoms vary with the source of contamination. Most types of food poisoning cause one or more of the following signs and symptoms: nausea, vomiting, watery diarrhea, abdominal pain and cramps and fever Signs and symptoms may start within hours after eating the contaminated food, or they may begin days or even weeks later.

ASEPTIC MENINGITIS IN ADULTS CAUSING BY VIRUS, BACTERIA, DRUG WITH SPECIAL REFERENCES TO ZOONOTIC PARASITES.

Diagnosis of a patient with aseptic meningitis may be so-difficult because of the large vanety of potential etiologic agents as viruses, fungi, parasites and some drugs and the overlap between self-limited viral illnesses and potentially fatal bact~nial infections.

TICK-BORNE INFECTIOUS DISEASES WITH REFERENCE TO EGYPT.

Ticks are hematophagous ectoparasites of man, domestic and street animals, and birds of health and economic hazard worldwide. They transmit many micro-organisms and protozoan infectious diseases and their toxins cause different signs and symptoms that may be fatal according to the infesting tick saliva protein. In Egypt where there are many rural and urban areas, so many genera and species of ticks are encountered.

EGYPTIAN EOSINOPHILIC AND INFECTIOUS MENINGOENCEPHA- LITIS AND THEIR IMPACT ON PSYCHOLOGICAL ASPECTS.

Meningoencephalitis is an acute inflammation of the brain and spinal cord & their covering protective membranes. Meningitis can be life-threatening because of the inflammation's proximity to the brain and spinal cord; therefore, the condition is classified as a medical emergency. The commonest symptoms of meningitis are headache and neck stiffness associated with fever, confusion or altered consciousness, vomiting, and an inability to tolerate light (photophobia) or loud noises (phonophobia).

THE ARTHROPOD-BORNE ONCHOCERCIASIS: IS IT DESERVED TO BE NEGLECTED?

Onchocerciasis a filarial parasitic nematode, also known as river blindness and Robles disease, is a neglected tropical disease infecting more than 18 million people mainly in sub-Saharan of Africa, the Middle East, South and Central America and many other countries. Disease infectivity initiates from Onchocerca volvulus (Filarioidea: Onchocercidae) transmitted by the blackfly, Simulium sp. which introduces the infective stage larva with its saliva into the skin.

Entomophobia, acarophobia, parasitic dermatophobia or delusional parasitosis.

Entomophobia or acarophobia, parasitic dermatophobia (PD) or delusional parasitosis (DP) is a disorder in which affected individuals has the mistaken but unshakable belief (delusion) that they are infected by insects, spiders, scorpion, ticks, mites, parasitic worms, bacteria, or other living organisms. As with all delusions, this belief cannot be corrected by reasoning, persuasion, or logical argument. To avoid them, they may always be cleaning rooms, floors, doors, windows and scratching.

Aedes aegypti re-emerging in Egypt: a review and what should be done?

Mosquitoes are main vectors of varieties of pathogenic agents affecting man and animals. There-emergencein Aswan and approach of Aedesa egypti, the vector of the Dengue hemorrhagic fever, Yellow fever and Chikungunya fever, which are encountered in Africa, needs to alert for this public health threat. The presence of Dengue and dengue hemorrhagic fever in Saudi Arabia is another issue.

Maternal brucellosis and human pregnancy.

Brucellosis is a worldwide zoonotic gram-negative bacterium of worldwide distribution. Its role in causing miscarriage in animals is well documented. Data on its role in human abortion are very few.

Threat of dengue fever and dengue haemorrhagic fever to Egypt from travelers.

Dengue (DF) and dengue hemorrhagic fevers (DHF) are present in urban and suburban areas in the Americas, South-East Asia, the Eastern Mediterranean and the Western Pacific, but dengue fever is present mainly in the rural areas of Africa. Several factors have combined to produce epidemiological conditions in developing countries in the tropics and subtropics that favour viral transmission by the main mosquito vector, Aedes aegypti as the rapid population growth, rural-urban migration, inadequate basic urban infrastructure (eg. the unreliable water supply leading householders to store water in containers close to homes) and the increase in volume of solid waste, such as discarded plastic containers and other abandoned items which provide larval habitats in urban areas.

Severity of erectile dysfunction could predict left ventricular diastolic dysfunction in patients without overt cardiac complaint.

Introduction: It has been repeatedly demonstrated that presence of erectile dysfunction (ED) may predate the occurrence of overt event of coronary artery disease. However, the association between severity of ED and left ventricular diastolic dysfunction (LVDD) was rarely reported.

Aim: The aim of this study was to assess the association between severity of ED and LVDD in patients without overt cardiac complaint.

Clonorchis sinensis a new report in Egyptian employees returning back from Saudi Arabia.

Clonorchis sinensis, or Chinese liver fluke, is a parasite of the fish-eating mammals endemic in the East Asia, Far East, particularly in China, Japan, Taiwan, Vietnam, and Korea and among immigrant refugees to European Union and Eastern Mediterranean Countries. This paper reported infection among Egyptian family who practice consumption of imported fishes from the Far East. Diagnosed was based on detection of its characteristic eggs, positive specific ELISA, radiological and family behavior and feeding habit history.

Zoonotic brucellosis: an underestimated or misdiagnosed disease in Egypt.

Ectopic fascioliasis (EF) has direct and indirect effects on both humans and animals. The phenomenon of EF was individual cases in the period from 1950 up to the end of last century. From the period of 2000 up to 2006, plenty of researches were on EF in the developed and undeveloped countries.

Lupus nephropathy: clinical, immunohistochemistry and quantitative morphometric analysis studies.

Lupus nephritis includes a wide range of parenchymal injuries and severity. Better predictors to outcome are needed for patients newly diagnosed with lupus nephritis, so that an appropriate management strategy may be selected. This study aimed to determine whether the ratio of hepatocyte growth factor (HGF) to transforming growth factor beta 1 (TGF beta1) in lupus nephritis could be a prognostic factor for response to therapy with cyclophosphamide and steroids at six months.

Mirazid in treatment of three zoonotic trematodes in Beni-Sweif and Dakhalia Governorates.

A total of 60 patients with schistosomiasis (40), fascialiosis (15) and heterophyiasis (5) were selected Beni-Sweif and Mansoura Districts and subjected to history taking, clinical examination, Kato thick smear, sedimentation and hatching test (for schistosomiasis cases) at the beginning of the study, 2 & 3 months after treatment with Oleo-resin of Myrrh (Mirazid) in a dose of 10 mg/kg/day for 6 consecutive days an hour before breakfast. The results showed a significant improvement in symptoms with minimal negligible or no side effects. The cure rates, 2 & 3 months after treatment were 80.

A study on the prevalence of house dust mites in Al-Arish city, North Sinai Governorate, Egypt.

Free living mites comprise a huge and various groups of tiny arthropods in the class Arachida, mainly of the Pyroglyphidae family. Exposure to allergens derived from house dust mite (HDM) feces is a postulated risk factor for allergic sensitization, asthma development and asthma morbidity. However, practical and effective method to mitigate these allergens in low-income, urban home environments remains elusive.
