- The aim of this study was to establish the degree to which a standardized test based on laser Doppler blood flow measurement is dependent on the particular equipment set-up being used. For this purpose, we examined finger skin blood flow with laser Doppler instruments in 20 healthy subjects. In laser Doppler perfusion monitoring (LDPM), we used a custom-made probe with two detecting fibers placed 0.25 and 1.2 min from the illuminating fiber, respectively, and two laser Doppler perfusion imagers (LDPI) with a wavelength of 632.8 nm and 780 rim, respectively. Warming of the hand was achieved with a Peltier element, and reflex vasoconstriction was induced by immersing the other hand for 3 min into a water bath kept at 15 degrees C. As a measure for the change in skin blood flow, a vasoconstriction index (VAC: cooling/before cooling) was calculated and used for the comparison of the different devices. VAC values gathered around 0.6 for all devices. However, LDPI with a wavelength of 632.9 nm showed a slightly higher VAC index, and the difference was significant. We conclude that using a standardized test is the most appropriate for monitoring changes in blood flow rather than recording and comparing discrete values in intermittent recordings. Although a difference was noted when comparing the devices, different fiber separations and wavelengths seem then to be of little consequence. (c) 2005 Published by Elsevier Inc.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Dercum's disease (DD) is characterised by obesity and chronic pain (> 3 months) in the adipose tissue. The pathogenesis of DD is unknown, but inflammatory components have been proposed. In previous reports and studies, an inconsistent picture of the histological appearance of the adipose tissue in DD has been described. The aim of this investigation was to examine the histological appearance of adipose tissue in patients with DD, with particular focus on inflammatory signs. METHODS: Fat biopsies were sampled from painful regions from 53 patients with DD. In 28 of the patients, a control adipose tissue biopsy was taken from a location where the patient did not experience any pain. In addition, fat biopsies were sampled from 41 healthy pain-free obese control patients and 11 healthy pain-free normal weight control patients. The extent of inflammation was evaluated on histological sections stained with haematoxylin-eosin. RESULTS: There was no statistically significant difference in the extent of inflammation between the biopsies from the painful knee and the biopsies from the non-painful area (p = 0.5), nor between the biopsies from the abdomen, and the biopsies from the non-painful area (p = 0.4), in patients with DD. A statistically significant difference in extent of inflammation was observed between DD and obese control patients regarding the abdomen (p = 0.022), but not the knee (p = 0.33). There were no differences in extent of inflammation between DD patients and normal weight controls (p = 0.81). CONCLUSION: The findings suggest that there is an inflammatory response in the adipose tissue in DD. However, this response is not more pronounced than that in healthy obese controls. This contradicts inflammation as the aetiology of DD.

- Introduction: Oncoplastic breast surgery (OBS) has developed as an extension of breast-conserving surgery (BCS) in an effort to improve esthetic and functional outcome following surgery for breast cancer. The aim of the present study was to evaluate the possible benefits of OBS, as compared with BCS, with regard to health-related quality of life (HRQoL), using patient-reported outcome measures (PROMs). Patients and methods: Patients treated with OBS (n = 200) and BCS (n = 1304) in the period 1 January 2008 to 31 December 2013 were identified in a research database and in the Danish Breast Cancer Cooperative Group (DBCG) registry. Data on patient, tumor, and treatment characteristics were retrieved from the DBCG registry. Patients were sent a survey including the Breast-Q™ BCT postoperative module and a study-specific questionnaire (SSQ) in 2016. A good outcome in the Breast-Q module was defined as above the median. OBS was compared to BCS using a logistic regression analysis, and then adjusted for potential confounders, yielding odds ratios (OR) with 95% confidence intervals. Results: There was a statistically significant better outcome considering the HRQoL domain “Psychosocial Well-being “ for patients treated with OBS as compared with BCS (OR 2.15: 1.25–3.69). No statistically significant differences were found for the domains “Physical Well-being” (0.83: 0.50–1.39), “Satisfaction with Breast” (0.95: 0.57–1.59), or “Sexual Well-being” (1.42: 0.78–2.58). Conclusion: The present study indicates better outcomes of HRQoL for breast cancer patients treated with OBS as compared to patients treated with BCS. There was no increase in physical discomfort among OBS patients despite more extensive surgery.

- Laser Doppler flowmetry (LDF) was used to study skin blood flow in the finger tip and on the dorsum of the hand in healthy volunteers. Vasodilatation in the finger tip was induced by immersing the arm in water at 42 degrees C, and vasodilatation in the dorsum of the hand by intracutaneous injection of dihydralazine. Simultaneous measurements were performed using venous occlusion plethysmography (finger tip) and 133Xe clearance (dorsum of hand). Three output signals from the laser Doppler flowmeter were recorded. The LDFPf-1 value is linearly related to the blood flow, provided the concentration of blood cells in the scattering volume is low. The LDFPf-2 value is generated by a signal processor designed to give linearity even at higher concentrations of moving blood cells (CMBC), the latter quantity being reflected by the CMBC value. During vasodilatation by immersion, all laser Doppler values from the finger tip increased but less than the total finger blood flow as measured using venous occlusion plethysmography. Intracutaneous injection of dihydralazine in the dorsum of the hand caused markedly increased CMBC values and the increase in LDFPf-2 was significantly greater than that of LDFPf-1. The increase in 133Xe clearance was less pronounced. The results indicate that capillary blood flow as well as blood flow in vessels below the capillary level contribute to the Doppler signal. However, flow through the arteriovenous shunts in the finger tip seems to be only partially registered by the laser Doppler technique. The higher the CMBC value, the more obvious is the difference between LDFPf-1 and LDFPf-2 values. When using laser Doppler flowmetry, the addition of CMBC value registration may be helpful in clarifying changes in microvascular blood flow.

- We compared facial growth in patients with bilateral complete cleft lip and palate (BCLP) in whom the palate had been repaired by the von Langenbeck procedure at the age of 14 months (L-14), or by the Wardill procedure at 18 months (W-18). A total of 151 unaffected subjects were used as a reference group. Thirty-six adult patients, 26 in the L-14 group, and 10 in the W-18 group, were investigated clinically and with lateral skull radiography, and they also filled out a questionnaire about their dental condition. Multiple linear regression was used to analyse the effect of surgical strategy, sex, and the presence of a velopharyngeal flap on several dependent variables indicating sagittal and vertical jaw relations, and inclination of incisors. The BCLP group was characterised by a pre-normal basal relation (ss-n-sm), retroclined upper (ILs/NL) and lower (ILi/ML) incisors, maxillary retrognathism (s-n-ss) in men, larger maxillary plane angle (NSL/NL) in women, larger mandibular plane (NSL/ML) and intermaxillary vertical relation (NL/ML) in men, and smaller anterior facial height (n-gn) and upper anterior facial height (n-sp). In the BCLP group, differences in outcomes could be explained only by sex. The sagittal jaw base relation (ss-n-sm) was significantly smaller in men than in women, whereas the total anterior facial height (n-gn) was greater in men. Lateral crossbite was found in about 75% of patients. About 70% were satisfied with their dental condition. The choice of surgical strategy had no significant influence on the variables measured on facial morphology.

- Objective: To describe and compare speech and phonology at age 3 years in children born with unilateral complete cleft lip and palate treated with three different methods for primary palatal surgery. Design: Prospective study. Setting: Primary care university hospitals. Participants: Twenty-eight Swedish-speaking children born with nonsyndromic unilateral complete cleft lip and palate. Interventions: Three methods for primary palatal surgery: two-stage closure with soft palate closure between 3.4 and 6.4 months and hard palate closure at mean age 12.3 months (n = 9) or 36.2 months (n = 9) or one-stage closure at mean age 13.6 months (n = 10). Main Outcome Measures: Based on independent judgments performed by two speech-language pathologists from standardized video recordings: percent correct consonants adjusted for age, percent active cleft speech characteristics, total number of phonological processes, number of different phonological processes, hypernasality, and audible nasal air leakage. The hard palate was unrepaired in nine of the children treated with two-stage closure. Results: The group treated with one-stage closure showed significantly better results than the group with an unoperated hard palate regarding percent active cleft speech characteristics and total number of phonological processes. Conclusions: Early primary palatal surgery in one or two stages did not result in any significant differences in speech production at age 3 years. However, children with an unoperated hard palate had significantly poorer speech and phonology than peers who had been treated with one-stage palatal closure at about 13 months of age.

Tidskriftsartikel (refereegranskat)abstract
- A Caucasian female patient in her 90s was referred to the department of plastic and reconstructive surgery for surgical removal of a large invasive squamous cell carcinoma on the anterior chest wall. A skin biopsy prior to the referral indicated that the tumour was moderately differentiated. The patient suffered from severe congestive heart failure with a mechanical valve prosthesis and atrial fibrillation, and was therefore treated with anticoagulants. Hence, a surgical procedure would be hazardous. Therefore, other treatment options were considered. The principal aim was to reduce the amount of tumour tissue to an appropriate size suitable for later excision with primary wound closure. After interdisciplinary discussions, curettage and electrodessication combined with photodynamic therapy was judged the best alternative treatment in this case. At the 1.5 years follow-up after the intervention there was no indication for further surgery. The patient was at that stage content with the treatment and its outcome.

- Introduction Hypospadias is one of the most common congenital anomalies. There are many studies describing successful initial repair, but there are few studies examining long-term result. The aims of this study were to evaluate our patients that have been reconstructed for hypospadias and undergone final clinical examination after puberty and to assess how long clinical follow-up time is warranted after hypospadias repair.Patients and Methods A standard protocol, with visits at ages 7, 10, 13 and a final clinical examination at the age of 16, was followed. To objectify our long-term functional and aesthetic results, Hypospadias Objective Scoring Evaluation (HOSE) was used.Results A total of 114 boys reconstructed between 1989 and 2009 had undergone final clinical examination. Seventy-nine were classified as degree I, 25 as degree II, 6 degree III, 3 as degree IV, and 1 boy could not be classified retrospectively. Sixty-seven boys were operated on in stages according to Byars, 25 according to Mathieu, and 14 according to Scuderi. Only eight patients needed release of chordee and realignment of skin. Ten boys needed closure of fistulas and strictures had to be operated on in four cases. At the concluding visit, 86% of the patients had an excellent result according to the total HOSE score. It was noted that six patients had developed an incurvation between the prepubertal and postpubertal checkup.Conclusion It is important that the boys are followed according to a planned standardized protocol until they have passed puberty as incurvation may occur during puberty.

- Maxillary growth inhibition in patients with cleft lip and palate (CLP) is an undesired effect that may occur in the teens despite proper primary care. Dental malocclusion and distortion of facial appearance can be treated with external distraction osteogenesis (DO) of the maxilla. This entails a Le Fort I osteotomy, fastening a semi-circular distractor to the skull, distraction for three weeks, and fixation for three months before removal of the device.The aim of this descriptive long-term follow-up study was to evaluate DO of the maxilla from the patient-reported long-term perspective.Fourteen patients underwent a long-term follow-up including a questionnaire regarding their experience of DO. Sex, CLP diagnosis, age at DO and follow-up, and time required for active distraction and fixation were noted. Furthermore, documentation on rhinoplasty, lip plasty and velopharyngeal plasty after DO was registered. Objective results were assessed by a positive dental overjet in the front.Ten patients considered the distractor an everyday constraint, but all thought the procedure was worthwhile and would recommend it to others. Thirteen patients experienced improved bite and chewing, whereas one considered function unchanged. All were satisfied with their dental alignment. Three patients underwent a velopharyngeal plasty after DO. Moreover, six rhinoplasties and two lip plasties were performed.Despite a long and challenging treatment, teenagers and young adults with CLP and maxillary hypoplasia tolerate DO of the maxilla very well. Secondary measures to improve speech and appearance are often indicated.
