Traveling to high altitudes can expose the eye to reduced ambient cold and low-pressure environments. These conditions can affect the physiology of the eye and may result in ocular problems and visual disturbances. In this paper, ocular disorders related to high altitudes are briefly reviewed. Then, high-altitude ocular disorders are categorized in three parts: those related to dry and cold env...

We report three cases of infection due to the Gram-negative rod Ignatzschineria (Schineria) indica involving bacteremia and the urinary tract. Two cases were clearly associated with maggot infestation, and the third could conceivably have had unrecognized maggot infestation of the urinary tract. We believe these cases to be the first I. indica infections reported in association with maggot infe...

Leech infestation can cause many different clinical symptoms such as epistaxis, haemoptysis, haematemesis, and vaginal bleeding. Therefore leech infestation should be considered as a cause of unexplained severe anemia in rural areas where aquatic leeches are common. In this paper we report a case of pharyngeal leech infestation (Limnatis nilotica) presenting with haemoptysis, and epistaxis whic...

ABSTRACT: The poplar flat headed borer is one of important pests of poplar trees. This pest, attacks many poplars in physiological weakness condition and causes considerable damage in nurseries, plantation and wood-lots. This survey carried out in 2008 in order to study the effect of distance and planting system on damage rate of Melanophila picta in poplar/alfalfa agroforestry system in comple...

The literature on chronic pruritus, paresthesia and delusional infestation indicates that a wide variety of conditions ranging from AIDS to vitamin deficiencies may cause these symptoms. In many, or perhaps most of these cases, activation of itch pathways seems to be the underlying cause of the skin sensations and perhaps even the visual hallucinations characteristic of delusional infestation. ...

Ascariasis is a common soil-transmitted helminth infestation worldwide. Ascaris lumbricoides infestation is generally asymptomatic or cause nonspecific signs and symptoms. We report a 5-year-old male with hemophagocytic lymphohistiocytosis associated with A. lumbricoides infestation. The presented patient recovered completely after defecating an A. lumbricoides following intravenous immunoglobu...

Interactions of the parasitoid Lysiphlebus testaceipes (Cresson) and the greenbug, Schizaphis graminum (Rondani), on greenbug-resistant 'Cargill 607E' (antibiosis), 'Cargill 797' (primarily tolerance), and -susceptible 'Golden Harvest 510B' sorghum, Sorghum bicolor (L.) Moench, were tested using three levels of biotype I greenbug infestation. The parasitoid infestation rate was 0.5 female and 1...

A 3-yr field study was conducted at commercial juice grape (Vitis labrusca L.) vineyards to develop an economic injury level (EIL) for grape berry moth, Paralobesia viteana (Clemens) (Lepidoptera: Tortricidae) and to determine patterns of cluster injury. Infestation of grape clusters by P. viteana was measured biweekly from bloom until harvest, and fruit was sampled immediately before harvest t...

Infestation by blueberry gall midge, Dasineura oxycoccana Johnson, is common in northern highbush blueberries, but its effects on crop productivity are unknown. We examined whether infestation by blueberry gall midge reduces flower bud production when compared with uninfested shoots, and how infestation at different times affects the crop response. From the fall of 2009 to the spring of 2011, t...
