If there is persistent microalbumin over several repeated tests at different times, the risk of diabetic nephropathy and macrovascular disease are both higher.

Micropenis
A birth defect in which the penis is extremely small. The maximum stretched length is not greater than .5 standard deviation units (SDU) below the mean for age, and possibly as small as 5.0 SDU below. The diameter is correspondingly small, with extreme hypoplasia of the corpora cavernosa. As compared with a micropenis, the average adult penis's stretched length is 6.6 inches (16.7 cm), with a standard deviation of 0.77 inches ([1.95 cm) (Money, Lehne, and Pierre-Jerome, 1984) an exceptionally small penis that resembles the clitoris in size. A micropenis may carry the urethral tube or may be hypospadiac. Typically, it is formed mostly of skin, the body (corpora cavernosa) of the penis being hypoplastic. The condition is also known as microphallus or penile agenesis.

Mirroring
1) The empathic responsiveness of the parent to the developing child's grandiose-exhibitionistic needs. Parental expressions of delight in the child's activities signal that the child's wishes and experiences are accepted as legitimate. This teaches the child which of his or her potential qualities are most highly esteemed and valued. Mirroring validates the child as to who he or she is and affirms his or her worth. The process transforms archaic aims to realizable aims, and it determines in part the content of the self-assessing, self-monitoring functions and their relationships to the rest of the personality. The content of the superego is the residue of the mirroring experience. 2) A technique in psychodrama in which another person in the group plays the role of the patient, who watches the enactment as if gazing into a mirror. The first person may exaggerate one or more aspects of the patient's behavior. Following the portrayal, the patient is usually encouraged to comment on what he or she has observed.
Mood
A pervasive and sustained emotion that colors the perception of the world. Common examples of mood include depression, elation, anger, and anxiety.

Types of mood include: dysphoric, elevated, euthymic, expansive, irritable.
Mood-congruent psychotic features
Delusions or hallucinations whose content is entirely consistent with the typical themes of a depressed or manic mood. If the mood is depressed, the content of the delusions or hallucinations would involve themes of personal inadequacy, guilt, disease, death, nihilism, or deserved punishment. The content of the delusion may include themes of persecution if these are based on self-derogatory~ concepts such as deserved punishment. If the mood is manic, the content of the delusions or hallucinations would involve themes of inflated worth, power, knowledge, or identity, or a special relationship to a deity or a famous person. The content of the delusion may include themes of persecution if these are based on concepts such as inflated worth or deserved punishment.
Mood-incongruent psychotic features
Delusions or hallucinations whose content is not consistent with the typical themes of a depressed or manic mood. In the case of depression, the delusions or hallucinations would not involve themes of personal inadequacy, guilt, disease, death, nihilism, or deserved punishment. In the case of mania, the delusions or hallucinations would not involve themes of inflated worth, power, knowledge, or identity, or a special relationship to a deity or a famous person. Examples of mood-incongruent psychotic features include persecutory delusions (without self-derogatory~ or grandiose content), thought insertion, thought broadcasting, and delusions of being controlled whose content has no apparent relationship to any of the themes listed above.
