INTRODUCTION Pneumothorax is a well-recognised but rare adverse event related to acupuncture or deep dry needling (DDN) over the thorax. 2 This report of a pneumothorax resulting from DDN is unusual for a number of reasons: both the practitioner and the subject were doctors and both have contributed to this report; the practitioner was very experienced in DDN and had not knowingly caused such a...

OBJECTIVE Evaluating dry toilet use in a rural area of Colombia. METHOD Fifteen families were selected by convenience sampling from the rural area of a municipality in the Cundinamarca department in Colombia. A dry (composting) toilet was installed in one house and used for demonstration purposes over a five-month period. An ex-post evaluation was made concerning technical and economic matter...

OBJECTIVE To explore whether pain sensitivity plays a role in patients' experience of DED symptoms. DESIGN, SETTING, AND PARTICIPANTS A population-based cross-sectional study of 1635 fe...

This study investigates the relationship between tree growth and air mass type variability, using the spatial synoptic classification (SSC) in a bottomland slash pine forest in coastal Alabama (USA). The use of an air mass approach in dendroclimatology is somewhat unconventional and has not been fully explored. However, we believe that it may be useful because the air mass approach represents a...

Forests in the dry tropics differ significantly from forests in the humid tropics in their biomass and in their socio-ecological contexts, so it might be reasonable to assume that the dynamics that drive deforestation in these two settings would also differ. Until recently, difficulties in measuring the extent of dry tropical forests have made it difficult to investigate this claim empirically....

background: artificial tears have been among the first line of therapy in management of dry eye syndrome (des). this study was conducted to compare a local artificial tear with an imported one in reduction of des. this comparison would help to evaluate the cost and benefits of each drop in the proper management of des. m aterials and methods: in this double-blind randomized clinical trial study...

PURPOSE The lacrimal gland secretes water, electrolytes, and protein into the tear film. Decreased secretion from the lacrimal gland can lead to dry eye syndromes with deleterious effects on vision. Protein kinase C (PKC)-alpha plays a major role in cholinergic- and alpha1-adrenergic-induced protein secretion from the lacrimal gland. This study was undertaken to determine whether activation of ...

purpose: to evaluate tear film status and refractive conditions during and one month after treatment of acne vulgaris with isotretinoin (accutane). methods: this prospective study was performed on 26 eyes of 13 known cases of acne vulgaris. all cases were referred by a dermatologist and were candidates for low dose isotretinoin (0.5 mg/kg). full anterior and posterior segment examination and ob...
