The role of infants' mother-directed gaze, maternal sensitivity, and emotion recognition in childhood callous unemotional behaviours.

While some children with callous unemotional (CU) behaviours show difficulty recognizing emotional expressions, the underlying developmental pathways are not well understood. Reduced infant attention to the caregiver's face and a lack of sensitive parenting have previously been associated with emerging CU features. The current study examined whether facial emotion recognition mediates the association between infants' mother-directed gaze, maternal sensitivity, and later CU behaviours. Participants were 206 full-term infants and their families from a prospective longitudinal study, the Durham Child Health and Development Study (DCHDS). Measures of infants' mother-directed gaze, and maternal sensitivity were collected at 6 months, facial emotion recognition performance at 6 years, and CU behaviours at 7 years. A path analysis showed a significant effect of emotion recognition predicting CU behaviours (ß = -0.275, S.E. = 0.084, p = 0.001). While the main effects of infants' mother-directed gaze and maternal sensitivity were not significant, their interaction significantly predicted CU behaviours (ß = 0.194, S.E. = 0.081, p = 0.016) with region of significance analysis showing a significant negative relationship between infant gaze and later CU behaviours only for those with low maternal sensitivity. There were no indirect effects of infants' mother-directed gaze, maternal sensitivity or the mother-directed gaze by maternal sensitivity interaction via emotion recognition. Emotion recognition appears to act as an independent predictor of CU behaviours, rather than mediating the relationship between infants' mother-directed gaze and maternal sensitivity with later CU behaviours. This supports the idea of multiple risk factors for CU behaviours.

Forearm bone mineral density changes during postpartum and the effects of breastfeeding, amenorrhea, body mass index and contraceptive use.

UNLABELLED: Prospective cohort study performed to evaluate bone mineral density (BMD) changes up to 12 months postpartum of healthy women and its association with breastfeeding, contraceptive methods, amenorrhea, and body mass index (BMI). There is a trend in bone loss during the first 6 months with posterior recovery, with evidence of a protective effect of hormonal contraception. INTRODUCTION: This study was conducted to evaluate bone mineral density (BMD) changes during postpartum period among healthy women and its association with breastfeeding, use of contraceptive methods, amenorrhea and body mass index (BMI). METHODS: A prospective cohort study including 100 healthy women. Distal BMD was measured 7-10 days, 3, 6, and 12 months postpartum at the nondominant forearm using dual-energy X-ray absorptiometry. Data about breastfeeding duration, amenorrhea, contraceptive use and BMI were collected. RESULTS: Seventy-eight women had a complete set of BMD measurements. The mean duration of exclusive breastfeeding was 125.9 (±66.6) days, with a median total lactation period of 263.5 days. The mean duration of amenorrhea was 164.2 (±119.2) days. BMD measurements showed a significant decrease in the distal radius, however with no significance in the ultradistal radius. When considering only the nonhormonal contraceptive users, the difference at 12 months was significant. Multivariate analysis of variance showed that both BMI and contraceptive use were significantly correlated with BMD. Multiple linear regression analysis showed significant correlation of distal radius with baseline BMD at the same site, pregestational BMI, age, years of schooling and difference in BMI. For ultradistal radius, there was a significant direct correlation with its baseline BMD and pregestational BMI. CONCLUSIONS: There was a trend in bone loss during the first 6 months postpartum with posterior recovery. Also, hormonal contraceptive methods provided protection of bone loss. However, the long duration of breastfeeding and the follow-up were not sufficient to draw definitive conclusions on postweaning BMD conditions.

Accessory or additional renal arteries show no relevant effects on the width of the upper urinary tract: a 64-slice multidetector CT study in 1072 patients with 2132 kidneys.

OBJECTIVE: The aim of this study was to find out on an unselected patient group whether crossing vessels have an influence on the width of the renal pelvis and what independent predictors of these target variables exist. METHODS: In this cross-sectional study, 1072 patients with arterially contrasted CT scans were included. The 2132 kidneys were supplied by 2736 arteries. RESULTS: On the right side, there were 293 additional and accessory arteries in 286 patients, and on the left side there were 304 in 271 patients. 154 renal pelves were more than 15 mm wide. The greatest independent factor for hydronephrosis on one side was hydronephrosis on the contralateral side (p<0.0001 each). Independent predictors for the width of the renal pelvis on the right side were the width of the renal pelvis on the left, female gender, increasing age and height; for the left side, predictors were the width of the renal pelvis on the right, concrements, parapelvic cysts and great rotation of the upper pole of the kidney to dorsal. Crossing vessels had no influence on the development of hydronephrosis. Only anterior crossing vessels on the right side are associated with widening of the renal pelvis by 1 mm, without making it possible to identify the vessel as an independent factor in multivariate regression models. CONCLUSION: The width of the renal pelvis on the contralateral side is the strongest independent predictor for hydronephrosis and the width of the renal pelvis. There is no link between crossing vessels and the width of the renal pelvis.

[Functional retrourethral sling. A change of paradigm in the treatment of stress incontinence after radical prostatectomy]. / Die funktionelle retrourethrale Schlinge. Ein Paradigmenwechsel in der Therapie der Belastungsinkontinenz nach radikaler Prostatektomie.

The ever rising number of radical prostatectomies entails an increasing number of patients suffering from postoperative stress incontinence. Several minimally invasive techniques exist as surgical intervention options. All these procedures are based on an obstruction of the urethra. The functional retrourethral sling is a new and innovative sling suspension, which offers for the first time a non-obstructive functional therapeutic approach. The sling adjusts the changed anatomy after radical prostatectomy and exerts its effect by repositioning the lax and descended supporting structures of the sphincter in the former preoperative position. Thus continence can be achieved again. The success rate of this new technique is very good, yielding good results regarding both improving incontinence and continence rate. This new technique is secure and the results are reproducible.

Microcoil embolization of an arteriovenous fistula from the arteria bulbi penis to the corpus spongiosum penis in the treatment of erectile dysfunction: normal function regained immediately after intervention.

A 39-year-old man presented with erectile dysfunction that had persisted since its sudden onset 5 years ago. He exhibited none of the classic risk factors, and all attempts at medication had been unsuccessful. An ultrasound examination revealed the presence of an arteriovenous shunt in the corpus spongiosum penis. Selective digital subtraction angiography of the left internal pudendal artery showed an arteriovenous fistula from the arteria bulbi penis to the corpus spongiosum penis. The outflow of venous blood took place via the penile veins into the periprostatic vein plexus. Superselective catheterization of the arteria bulbi penis was performed with a 3 French coaxial catheter (Topaz Micro Coils; Micro Therapeutics, Inc, Irvine, CA) and it was occluded by inserting several platinum coils. 1 week after the procedure, the patient reported normal erectile function, which was subsequently maintained.

[The value of intravesical electrostimulation in the treatment of acute prolonged bladder overdistension]. / Der Stellenwert der intravesikalen Elektrostimulation in der Therapie der akuten prolongierten Blasenüberdehnung.

BACKGROUND: The effectiveness of intravesical electrostimulation (IVES) in the treatment of acute prolonged bladder overdistension (PBO) was investigated. METHODS: Sixteen patients (female 11, male 5, ø 54 years) after PBO (bladder filling volume: 1317+/-320 ml) were evaluated: 11 after surgery and 5 after polytrauma, psychosomatic disorder or LV4 fracture. After exclusion of a neurogenic aetiology and a urodynamic examination, IVES was performed besides IC or suprapubic catheter. RESULTS: Group 1: six patients with a weak detrusor (p(detr. max.)<30 cmH(2)O); group 2: ten patients had detrusor acontractility. After 25 IVES sessions, group 1 showed a significant increase of p(detr. max.) (p=0.01) as well as a decrease in PVR (31% to 3% of bladder capacity, p=0.02). Group 2 had no significant increase of p(detr. max). CONCLUSIONS: Two-thirds of patients with a weak detrusor after PBO will regain balanced voiding after IVES due to detrusor reinforcement. With an acontractile detrusor only bladder sensation improves.

Interim outcome of the single stage dorsal inlay skin graft for complex hypospadias reoperations.

PURPOSE: Despite high success rates for primary hypospadias repair, some cases require multiple procedures for ultimate reconstruction. We report our experience with single stage dorsal inlay urethroplasty using skin grafts for complex reoperations. MATERIALS AND METHODS: A total of 31 patients (mean age 13.8 years) with failed previous hypospadias surgery were included in the study. Indications included fistulas, strictures, diverticula and repair breakdown. The urethral plate had been removed or was severely scarred in all patients. A free penile or groin skin graft was sutured and quilted to the corpora cavernosa, guaranteeing sufficient blood supply. The neourethra was tubularized and covered with a tunica vaginalis or dartos flap, followed by glanuloplasty. Outcome analysis included urethrograms, urethral ultrasound and flow measurements. RESULTS: Foreskin was used in 15 cases, penile skin in 12 and inguinal skin in 4. Average graft length was 3.92 cm. A total of 20 patients required glanuloplasty with a skin graft extended to the tip of the glans. After a mean followup of 30.71 months 5 patients underwent redo surgery, for a complication rate of 16.1%. Urethral stricture of the proximal anastomosis was the most frequent finding. CONCLUSIONS: This single stage approach using dorsal skin grafts is a reliable method to create a substitute urethral plate for tubularization. Complication rates are equivalent to those of staged procedures. Foreskin should be used as a graft donor site to optimize the outcome if available. This approach represents a safe option for reoperations even if the urethral plate or midline penile skin is grossly scarred.

[Urethral trauma]. / Harnröhrentraumen.

Urethral lesions may be caused by blunt or penetrating objects in the course of accidents, or can be iatrogenic resulting from invasive measures such as catheterization or other major surgical measures (prostatectomy or sling operations for continence). They can also be caused by foreign bodies deliberately introduced into the urethra. Injuries may primarily affect the anterior or posterior urethra. Urethral reconstruction presupposes knowledge of the precise anatomy of the pelvic region. The surgical techniques used and the timing of reconstructive procedures will depend on the cause and nature of the urethral injury. A definitive surgical intervention in most cases of lesions resulting from accidents is not generally recommended, especially when the lesion is in the posterior urethra. A treatment algorithm should prevent post-surgical complications such as incontinence, impotence, recurring urinary tract infections, etc., necessitating multiple operations, and assure an adequate quality of life. Diagnostic clarification of the exact nature of urethral injuries requires high quality imaging studies by specialists in the field.

Late occurrence of bilateral tuberculous-like epididymo-orchitis after intravesical bacille Calmette-Guérin therapy for superficial bladder carcinoma.

We report a case of bilateral tuberculous-like epididymo-orchitis occurring 3 years after intravesical bacille Calmette-Guérin instillation therapy in an 83-year-old patient with proven superficial bladder carcinoma. The patient had no previous history of tuberculosis. Because of persistent inflammation and painful swelling of the epididymides and testes, the patient underwent bilateral orchiectomy. This case demonstrates the late adverse effects that can occur after intravesical BCG therapy, which in our patient ended in surgical removal of both gonads.

[Transrectal three dimensional sonography. Techniques and indications]. / Transrektale dreidimensionale Sonographie. Technik und Indikationen.

In 3-D transrectal ultrasound it is possible, for the first time, to investigate the region of interest in three planes simultaneously. Exact examination of the organs of the small pelvis as well as of pathologic changes in the region of the pelvic floor can be performed with this new imaging technique. The bulbourethral glands can be investigated routinely, which enables the diagnosis of cysts of these glands. The prostatic zones, their relations as well as the growth of the transitional zone during the development of benign prostatic hyperplasia can be visualized. Furthermore, 3-D transrectal ultrasound allows investigation of morphology and function of the rhabdosphincter. The contractility of the muscle can be quantified. 3-D ultrasound guided puncture and drainage of prostatic abscesses represents a minimally invasive therapeutic modality. This technique can be used to place needles as well as implants in the lower urinary tract. Generally, 3-D transrectal ultrasound offers new diagnostic and therapeutic possibilities.

Late urologic effects after adjuvant irradiation in stage I endometrial carcinoma.

OBJECTIVES: To evaluate the incidence and type of incontinence after external beam radiotherapy (RT) and brachytherapy. Distinct late effects on the urinary bladder can occur and are frequently mild after adjuvant RT for Stage I endometrial carcinoma. Not all side effects that impair quality of life (eg, urinary incontinence) are classified in the commonly used grading system. METHODS: Forty-one patients were evaluated for newly occurred urinary incontinence after adjuvant RT. The mean follow-up was 64.8 months, and the mean age was 62.1 years. The validated incontinence score from Gaudenz was used. Additionally, quality-of-life questions were asked. RESULTS: Overall, 22 (53.7%) of 41 patients complained of urinary incontinence. Urge incontinence was classified in 45.5% (10 of 22 patients) and stress urinary incontinence in 54.5% (12 of 22 patients). CONCLUSIONS: The onset of stress urinary incontinence after brachytherapy can be explained by anatomic findings, such as adverse affects to the nerve supply of the rhabdosphincter. According to our results, the exposure to additional external beam RT can cause urge incontinence. Patients and doctors must be aware that urinary incontinence, with an occurrence rate of more than 50%, represents the most common side effect after surgery and RT for Stage I endometrial carcinoma. We conclude that, depending on the type of RT, a stress incontinence rate of 24.4% and an urge incontinence rate of 29.2% is possible.

Evaluations of diapers containing absorbent gelling material with conventional disposable diapers in newborn infants.

We evaluated 149 infants diapered in either conventional cellulose core disposable diapers or diapers containing cellulose core with absorbent gelling material. The infants were evaluated from 1 day of age to 14 weeks of age for the prevalence and severity of diaper dermatitis. We identified a low prevalence of diaper dermatitis throughout the study period. At 14 weeks of age, we noted that infants in diapers containing absorbent gelling material had significantly less diaper dermatitis than those in conventional disposable diapers. Despite the overall low prevalence of diaper dermatitis in the newborn period, 7 of 204 infants evaluated had small skin erosions in the diaper area noted within the first 4 days of age. Both diaper types were associated with infants with erosions. This surprisingly high incidence of erosions in newborn infants suggests previously undocumented increased skin fragility of full-term infants.

Perianal cellulitis. Cutaneous group A streptococcal disease.

Five case reports of perianal cellulitis caused by group A beta-hemolytic streptococci are presented. These reports illustrate delays in diagnosis and therapy of this condition that may present as chronic diaper dermatitis, perirectal fissures, painful defecation, fecal hoarding behavior, or proctocolitis. One patient had associated guttate psoriasis. In children especially, guttate psoriasis should alert physicians to culture perirectal as well as pharyngeal sites for group A streptococci.
