Editorial Commentary: Iliopsoas Fractional Lengthening: Treating a Disease or a Symptom?

Arthroscopic iliopsoas fractional lengthening requires careful patient selection, specifically reproducible symptoms, confirmatory physical examination, suggestive imaging findings, and evaluation for microinstability. Resolution of hip snapping is expected in about 80% of cases, but there is a possibility of weakness and pain, presumably from microinstability from the loss of a dynamic anterior hip stabilizer.     

Lymphogranuloma venereum: biopsy, serology, and molecular biology.

A 21 year old woman presented with painful groin lymphadenopathy and malaise. Lymph node biopsy, to exclude atypical infection and malignancy, suggested the diagnosis of lymphogranuloma venereum. This diagnosis was confirmed by serology and polymerase chain reaction, with the patient subsequently admitting to a casual sexual contact within the United Kingdom. Alternative methods of investigation of this disease are discussed.     

Transitional properties of the mechanically evoked perioral reflex from infancy through adulthood

The organization of motor responses in the orbicularis oris muscle following the delivery of punctate mechanical inputs to vermilion skin of the lips was studied in a group of young infants, school-age children, and adults during periods of voluntary lip muscle activation. A specially designed multi-point array skin contactor, coupled to a position-servo controlled linear motor, was highly effective in driving the early component of the perioral reflex (R1). Overall, the evoked R1 response obtained from the infant was of variable amplitude relative to the children and adults, lacked response specificity, and occurred it a longer latency. This brainstem mediated sensorimotor action appears to take on several characteristics of the adult form by the age of 12. The emergence and maturation of mechanically evoked perioral reflexes is discussed in relation to the acquisition of motor skills, including speech and smiling.     

Effects of Positive and Negative Mood on Sexual Arousal in Sexually Functional Males

Effects of positive and negative musical mood induction on subjective and objective sexual arousal were examined in a group of sexually functional males (N = 24). Subjects evidenced significantly greater objective and subjective sexual response in the positive mood induction condition relative to both baseline and a neutral control condition. In contrast, the negative mood induction condition yielded significantly less objective sexual arousal than baseline and a neutral control condition. Data provide additional empirical support for the hypothesized impact of mood on sexual arousal.     

The effect of low dose lofepramine in depressed elderly patients in general medical wards.

A double-blind randomised controlled trial of the effect of low dose lofepramine (70 mg once daily) against placebo was carried out on depressed elderly inpatients on general medical wards for the elderly, comparing measures of depression and side-effects between the randomised groups. Patients were identified for the study using the Geriatric Depression Scale (GDS) and the Brief Assessment Schedule Depression Cards (BASDEC). Sixty-three subjects were randomised: 46 patients completed the entire trial of 28 days treatment. BASDEC and GDS were administered on day 8 post-admission, and depressed patients were randomised double-blind to either low dose lofepramine (70 mg daily) (n = 23) or placebo (n = 23). Assessment of changes in depressive states were made using the Montgomery Asberg Depression Rating Scale (MADRS) on days 8, 18 and 36 post-admission. Both groups improved by a similar amount during the trial. Lofepramine tended to be more effective than placebo in those patients who were more depressed (GDS > or = 18). On the other hand, subjects who were less depressed (i.e. GDS < 18) improved more on placebo than lofepramine. Low dose lofepramine may prove useful in moderately or severely depressed patients treated for only 4 weeks. However, low dose lofepramine is not indicated for mild (GDS 15-18) depression.
