| bed-wetting | The involuntary passage of urine at nighttime in children age 4 to 5 years. most bed-wetting stops by the age of three. Enuresis is twice as common in boys as in females. Causes have been attributed to delay in bladder muscle development, adjustment disorder (parents too controlling or aggressive, too early (and too coercive) of toilet training, diabetes and spinal cord lesions (rare). A urinary tract infection should be excluded in the cases of a sudden onset of bed-wetting. Treatment includes behaviour modification (rewarding good behaviour), supportive and helpful attitude by parents, limiting fluids at bedtime and alarm devices (a sleep pad that sets off an alarm when it gets wet). Vasopressin nasal spray has been used successfully to treat this condition in some children. (27 Sep 1997) |

| bedbugs | Bugs of the family cimicidae, genus cimex. They are flattened, oval, reddish insects which inhabit houses, wallpaper, furniture, and beds. C. Lectularius, of temperate regions, is the common bedbug that attacks man and is frequently a serious pest in houses, hotels, barracks, and other living quarters. It also attacks animals other than man. C. Rotundatus (hemipterus) of the tropics, also bites man. Other species of this family attack bats and various birds. Although bedbugs attack man when he is sleeping only to obtain a meal of blood, man himself does not transport the infestation from place to place: furnishings removed for cleaning are likely to result in infestation. Experiments have shown that bedbugs can transmit a variety of diseases, but they are not normal vectors under natural conditions. (12 Dec 1998) |
