[EX Q]: Traditionally cerebellar functions are thought to be related to control of tone, posture, gait, and coordination of skilled motor activity. However, there is an increasing body of evidence implicating the cerebellum in cognition, language, memory, and motor learning. Preterm infants are at increased risk of neurodevelopmental delay, cognitive dysfunction, and behavioral and emotional disturbances. The role of the cerebellum in these adverse outcomes is unclear.', 'The objective of this study was to determine whether absolute cerebellar volumes differ between term-equivalent preterm infants and term-born control infants and to assess whether cerebellar volume is influenced by any possible antenatal, perinatal, and postnatal factors.', 'The study compared the MR imaging cerebellar volume by using a manual quantification program of 113 preterm infants at term-equivalent age and 15 term-born control infants.', 'The median cerebellar volume of preterm at term-equivalent age was 25.4 cm3 and that of term-born control infants was 26.9 cm3. On initial analysis, there was a significant median difference of 2.0 cm3 (95% CI, 1.2 cm3 to 2.7 cm3) (2-sided P < .0001). However multiple regression analysis of perinatal variables showed that only infants with supratentorial lesions (P = .003) were significantly associated with the reduction in cerebellar volumes. The median cerebellar volumes were the following: supratentorial lesions, 18.9 cm3; no supratentorial lesions, 26.1 cm3; and term infants, 26.9 cm3 (analysis of variance, P < .0001). Hence, there was no significant difference in cerebellar volumes of preterm infants at term-equivalent age in the absence of supratentorial lesions. The median vermal volumes were 0.7 cm3 and were significantly related to cerebellar volumes both in preterm infants with and without lesions and in term-control infants.
[EX A]: Are smaller cerebellar volumes in very preterm infants at term-equivalent age associated with the presence of supratentorial lesions?

[EX Q]: Psychomotor abnormalities characterize both unipolar (UP) depression and bipolar (BP) depression. We aimed to assess their neurobiological correlates in terms of motor activity (AL) and resting-state cerebral blood flow (rCBF) and investigate their association in BP, UP, and healthy controls (HC).', 'We enrolled 42 depressed patients (22 BP, 20 UP) and 19 HC matched for age, gender, education, income. AL and rCBF were objectively assessed with the use of wrist actigraphy and arterial spin labeling. Group differences and the association of AL and rCBF were computed.', 'Activity level was significantly reduced in patients, but no difference was found between BP and UP. Increased perfusion was found in BP compared with UP and HC, in multiple brain areas. We found positive correlations of rCBF and AL in BP and UP, in different parts of the insula and frontal regions. Only BP showed a cluster in the left precentral gyrus. In HC, only inverse correlations of AL and rCBF were found.
[EX A]: Do distinct resting-state perfusion patterns underlie psychomotor retardation in unipolar vs. bipolar depression?

[EX Q]: To compare the safety and efficacy of patients undergoing dorsal penile plication with patients undergoing ventral and lateral plication.', 'A retrospective review was performed of all patients who underwent penile plication between 2007 and 2013. Plication was performed through a 2-cm longitudinal incision in the proximal or midpenile shaft without degloving. Plication sutures were placed in parallel opposite the angle of greatest curvature. Dorsal plication was performed with minimal displacement of the neurovascular bundle. Patient demographics, perioperative outcomes, and patient-reported outcomes were analyzed.', 'Of 215 patients who underwent penile plication, complete operative and patient-reported outcomes data were available for 118 (55%). Patients were grouped by location of plication: dorsal (n = 17 [14%]), ventral (n = 65 [55%]), and lateral (n = 36 [31%]). Mean age (52-58 years; P = .51) and preoperative curvature (36-51°; P = .78) were similar among the 3 groups. Each group required a similar number of sutures (8-9; P = .18) to achieve similar correction (37-45°; P = .33). Patients completed a satisfaction survey at a mean of 15 months (range, 1-41 months) after surgery. All groups reported equally high rates of satisfaction for penile curvature (P = .64), penile rigidity (P = .64), strength of erection (P = .98), and overall satisfaction (P = .75). Although each group reported subjective decrease in penile length (P = .10), objective length loss occurred on a small scale (mean length loss for all groups, 0.3-0.8 cm; P = .24).
