[Cognitive behavioral therapy in combination with pharmacotherapy for adults with ADHD]. / Cognitieve gedragstherapie bij medica-menteuze behandeling van ADHD bij volwassenen.

BACKGROUND: Treatment options for attention deficit hyperactivity disorder (ADHD) in adults consist of psycho-education, cognitive behavioral therapy (CBT), pharmacotherapy or a combination thereof. AIM: To investigate the effect of CBT combined with pharmacotherapy on the quality of life in adults with ADHD compared to medication alone. METHOD: In this multicenter prospective cohort study a total of 627 patients were included, 305 where included in the medication only group and 322 in de combination group (CBT and medication). The Adult ADHD Quality-of-Life scale (AAQoL) was conducted at baseline and at the end of treatment. RESULTS: The quality of life as measured by the AAQoL increased significantly in both groups but was not significantly different between the two groups (p = 0.33). CONCLUSION: To our knowledge, this is the first study to describe the effect of CBT as an addition to ADHD drug therapy on the quality of life in adults. Contrary to our expectations, there was no significant effect of CBT as an addition to drug therapy on the quality of life.

The "nugget design": A modified segmental gracilis free flap for small-sized defect reconstruction on the lower extremity.

BACKGROUND: Little attention has been given to the segmental free gracilis muscle flap supplied by secondary proximal pedicles. We introduce a technical refinement for small-sized three-dimensional defect reconstruction on the foot. METHODS: Between November 2013 and August 2016, three patients with a mean age of 66 years (range 47-70 years) were included. A segmental gracilis free flap supplied by the most proximal secondary pedicle was harvested according to a modified "nugget design" to treat small-sized defects on the lower extremity requiring dead space reconstruction. Minor and major complications, sensitivity with Semmes-Weinstein monofilament test, soft tissue stability and patient satisfaction at final follow-up were recorded. RESULTS: In one case, a segmental gracilis muscle was used for dorsal foot reconstruction after debridement of metatarsal phalanx I with osteomyelitis. In two cases, the segmental gracilis free muscle was harvested for defect reconstruction on the right plantar foot after excision of a melanoma. The first patient required revision after partial failure of the initial segmental gracilis free muscle flap. Overall, good results in foot function and a high degree of patient satisfaction was achieved (Likert scale 9.7, range 9-10) after a mean follow-up of 13 months (range 3-24 months). CONCLUSIONS: Taken from the very proximal dorsal part of the gracilis muscle supplied by the most proximal secondary pedicle and leaving the vast majority of the muscle intact preserves the option to harvest a normal gracilis flap. This technique is especially suitable for small, three-dimensional defects on the lower extremity.

The medial femoral trochlea flap with a monitor skin island-Report of two cases.

In this report, we present two cases of the bony reconstruction with the medial trochlea (MFT) flap including a skin island that was used to monitor the perfusion of flap in the postoperative period. Between March 2013 and April 2015, we performed surgery on two patients who suffered from scaphoid and talus non-union after trauma and initial treatment by osteosynthesis. A skin island (1 cm × 1 cm and 3 cm × 1 cm, respectively) was included with the osseous flap (1.6 cm × 1 cm × 1 cm and 2 cm × 3 cm × 2 cm, respectively) to assess the perfusion of the flap. The design of the skin island was based on either the saphenous artery perforator or a cutaneous perforator of the descending genicular artery. Both flaps remained viable throughout the postoperative period, and there were no donor site complications. After a follow-up of 36 and 11 months, bony union was observed in both patients with a high degree of satisfaction. Thus, a MFT flap with a skin island could be a tool to assess the perfusion of the flap in the early postoperative period. © 2016 Wiley Periodicals, Inc. Microsurgery 37:431-435, 2017.

Defect reconstruction over the olecranon with the distally extended lateral arm flap.

Defect reconstruction over the olecranon should be reliable, quick, relatively simple and with minimal complications. More recently, perforator flaps have been described with the benefit of minimal donor site morbidity when compared with muscle flaps or flaps relying on the major arteries of the upper extremity. So far, most of these flaps were harvested on the upper arm and rotated 180° into the defect. The aim of the present study was to analyse the results with the proximally based, distally extended lateral arm flap for soft-tissue reconstruction over the olecranon. The subcutaneous tissue layer in this area is thinner than in the upper arm, and less rotation of the pedicle is necessary. The location of the perforator just proximal to the lateral epicondyle and the precise territory of the flap are well known. Nine consecutive male patients with a mean age of 57±27 years presenting with soft-tissue defects after surgical treatment of bursitis (eight cases) or a pressure sore (one case) were operated on. The mean operation time was 60±15 min. In eight of the nine cases, the flap healed uneventfully or with a minor complication (fistula). One patient underwent revision surgery due to marginal flap necrosis. The defect was closed with a local advancement flap. In conclusion, the flap was reliable, relatively simple and quick to harvest, and yielded acceptable aesthetic results with minimal bulging over the olecranon. Postoperative recovery was relatively painless and short.

Superior epigastric artery perforator flap for sternal osteomyelitis defect reconstruction.

Sternal osteomyelitis after median sternotomy is associated with considerable morbidity and mortality. Combined with radical debridement, muscle and less frequently omentum flaps are used to reconstruct the resulting defects. In this study, we present our experience with the fasciocutaneous superior epigastric artery perforator (SEAP) flap for defect closure. After resection of the entire sternum, including the costochondral arches and the sternoclavicular joints, the repair of the defect was performed with the perforator flap without any re-stabilisation of the thoracic wall. A consecutive series of nine patients with a mean age of 69 ± 6 years were reconstructed with the SEAP flap. The mortality rate was zero. One patient developed a mediastinal haematoma and required five re-interventions by the cardiothoracic surgeons and thereafter a revision to close a small-wound dehiscence at the tip of the flap. Another two patients developed partial necrosis of the flap that could be managed conservatively. One patient had a revision for a seroma on the donor site, resulting in a 100% closure rate of the defect; there were revisions in two out of nine patients. The underlying infection was controlled by debridement, antibiotic therapy and flap closure in all cases. The overall success of the procedure was satisfactory; however, the local complication rate was relatively high with three out of nine patients on the flap side and one of nine on the donor site. Major advantages of the perforator flap in this highly morbid patient cohort are that the operation is relatively quick, muscle tissue is spared and re-education facilitated.

Bovine dermal matrix as coverage of facial nerve grafts.

Introduction. Soft tissue defects over functional structures represent a challenge for the reconstructive surgeon. Often complex, reconstructive procedures are required. Occasionally, elderly or sick patients do not qualify for these extensive procedures. Case. We present the case of a 91-year-old lady with large hemifacial defect with exposed bone and nerves after tumor resection. We first performed radical resection including the fascia of the temporalis muscle and the frontal branch of the facial nerve. Due to the moribund elderly patient with a potentially high perioperative risk, we decided against flap reconstruction but to use bovine collagen/elastin matrix and split thickness skin graft. Results. No postoperative complications occurred and STSG and matrix healed uneventfully. Discussion. In selected cases, where complex reconstruction is not appropriate, this procedure can be a safe, easy, and fast alternative for covering soft tissue defects even on wound grounds containing nerve grafts.

The posterior intercostal vein: a thermoregulatory gateway to the internal vertebral venous plexus.

The internal vertebral venous plexus (IVVP) plays a putative role in thermoregulation of the spinal cord. Cold cutaneous venous blood may cool, while warm venous blood from muscles and brown fat areas may warm the spinal cord. The regulating mechanisms for both cooling and warming are still unknown. Warm venous blood mainly enters the IVVP via the intervertebral veins. In the thoracic area these veins are connected to the posterior intercostal veins. In this study, anatomical structures were investigated that might support the mechanisms by which warmed venous blood from the intercostal muscles and the recently described paravertebral patches of brown adipose tissue are able to drain into the vertebral venous plexus. Therefore, tissue samples from human cadavers (n = 21) containing the posterior intercostal vein and its connections to the IVVP and the azygos veins were removed and processed for histology. Serial sections revealed that the proximal parts of the posterior intercostal veins contained abundant smooth muscle fibers at their opening into the azygos vein. Furthermore, the walls of the proximal parts of the posterior intercostal veins contain plicae that allow the vessel to dilate, thereby allowing it to serve as a pressure chamber. It is suggested that a cold induced closure of the intercostal/azygos opening can result in retrograde blood flow from the proximal posterior intercostal vein towards the IVVP. This blood flow would be composed of warm blood from the paravertebral brown adipose tissue and blood containing metabolic heat from the muscles draining into the intercostal veins.

Treatment of basal cell carcinoma with surgical excision and perilesional interferon-α.

UNLABELLED: The classical treatment of basal cell carcinoma (BCC) is surgical removal. Recent scientific interest has shifted towards alternative, non-surgical interventions in order to decrease the morbidity associated with surgical excision. AIM: This study aims to evaluate a novel approach that combines surgical excision with perilesional interferon injection in a pilot study. METHOD: A total of 23 patients with facial nodular/solid BCC were enrolled and randomised to receive surgical removal with frozen-section control followed by a single perilesional infiltration of either interferon-α or Ringer's lactate. Patients were evaluated for signs of local complications and recurrence after a minimal follow-up of 1 year. RESULTS AND CONCLUSION: No major complications occurred after infiltration of interferon. One patient required oral antibiotics in the interferon group and two patients showed a small wound dehiscence. At the 1-year follow-up, one patient suffered from a recurrence in the control group. No recurrence was observed in the interferon group. A single perilesional infiltration of interferon-α was safe and did not increase the local complication rate. No recurrence was observed. A larger study is required to analyse the potential of this combination approach in order to minimise the safety margin and thereby decrease the morbidity associated with surgery while improving the cure rate.

First-aid with warm water delays burn progression and increases skin survival.

INTRODUCTION: First aid treatment for thermal injuries with cold water removes heat and decreases inflammation. However, perfusion in the ischemic zone surrounding the coagulated core can be compromised by cold-induced vasoconstriction and favor burn progression. The aim of this study is to evaluate the effect of local warming on burn progression in the rat comb burn model. METHODS: 24 male Wistar rats were randomly assigned to either no treatment (control) or application of cold (17 °C) or warm (37 °C) water applied for 20 min. Evolution of burn depth, interspace necrosis, and microcirculatory perfusion were assessed with histology, planimetry, respectively with Laser Doppler flowmetry after 1 h, as well as 1, 4, and 7 days. RESULTS: Consistent conversion from a superficial to a deep dermal burn within 24 h was obtained in control animals. Warm and cold water significantly delayed burn depth progression, however after 4 days the burn depth was similar in all groups. Interspace necrosis was significantly reduced by warm water treatment (62±4% vs. 69±5% (cold water) and 82±3% (control); p<0.05). This was attributed to the significantly improved perfusion after warming, which was present 1 h after burn induction and was maintained thereafter (103±4% of baseline vs. 91±3% for cold water and 80±2% for control, p<0.05). CONCLUSION: In order to limit damage after burn injury, burn progression has to be prevented. Besides delaying burn progression, the application of warm water provided an additional benefit by improving the microcirculatory perfusion, which translated into increased tissue survival.

Erythropoietin in the prevention of experimental burn progression.

BACKGROUND: Damage control is essential in first aid of burn lesions. The aim of the present study was to investigate whether systemic erythropoietin (EPO) administration could prevent secondary burn progression in an experimental model. METHODS: The burn comb model creates four rectangular burn surfaces intercalated by three unburned zones prone to progression. Twenty-one Wistar rats were randomized to a control group or to receive intraperitoneal EPO (500 units per kg) once a day for 5 days starting 45 min (EPO45min) or 6 h (EPO6h) after burn injury. Histological analyses assessing burn depth, inflammation and neoangiogenesis, planimetric evaluation of burn progression, and laser Doppler flowmetry to assess perfusion were performed after 1, 4 and 7 days. Final scarring time and contracture rate were assessed once a week. RESULTS: Burn progression was decreased significantly with EPO45min but not EPO6h; progression of burn depth stopped in the intermediate dermis (mean(s.e.m.) burn depth score 3·3(0·6) for EPO45min versus 4·7(0·3) and 5·0(0·0) for EPO6h and control respectively on day 7; P = 0·026) and the surface extension was significantly reduced (45(8), 65(4) and 78(4) respectively on day 7; P = 0·017). This was paralleled by faster re-establishment of perfusion with EPO45min (114(5) per cent on day 4 versus 85(6) and 91(3) per cent for EPO6h and control respectively; P = 0·096). The reduction in progression resulted in a decreased healing time (7·3(0·7) weeks for EPO45min versus 11·5(1·0) and 10·8(0·5) weeks for EPO6h and control; P = 0·020) and contracture rate (P = 0·024). CONCLUSION: Early EPO prevented burn progression, mainly by improved vascular perfusion.

Ghrelin protects musculocutaneous tissue from ischemic necrosis by improving microvascular perfusion.

Persistent ischemia in musculocutaneous tissue may lead to wound breakdown and necrosis. The objective of this experimental study was to analyze, whether the gastric peptide ghrelin prevents musculocutaneous tissue from necrosis and to elucidate underlying mechanisms. Thirty-two C57BL/6 mice equipped with a dorsal skinfold chamber containing ischemic musculocutaneous tissue were allocated to four groups: 1) ghrelin; 2) N(ω)-nitro-l-arginine methyl ester (l-NAME); 3) ghrelin and l-NAME; and 4) control. Microcirculation, inflammation, angiogenesis, and tissue survival were assessed by fluorescence microscopy. Inducible and endothelial nitric oxide synthase (iNOS I and eNOS), vascular endothelial growth factor (VEGF), as well as nuclear factor κB (NF-κB) were assessed by Western blot analysis. Ghrelin-treated animals showed an increased expression of iNOS and eNOS in critically perfused tissue compared with controls. This was associated with arteriolar dilation, increased arteriolar perfusion, and a sustained functional capillary density. Ghrelin further upregulated NF-κB and VEGF and induced angiogenesis. Finally, ghrelin reduced microvascular leukocyte-endothelial cell interactions, apoptosis, and overall tissue necrosis (P < 0.05 vs. control). Inhibition of nitric oxide by l-NAME did not affect the anti-inflammatory and angiogenic action of ghrelin but completely blunted the ghrelin-induced tissue protection by abrogating the arteriolar dilation, the improved capillary perfusion, and the increased tissue survival. Ghrelin prevents critically perfused tissue from ischemic necrosis. Tissue protection is the result of a nitric oxide synthase-mediated improvement of the microcirculation but not due to induction of angiogenesis or attenuation of inflammation. This might represent a promising, noninvasive, and clinically applicable approach to protect musculocutaneous tissue from ischemia.

Silicone moulding for pressure sore debridement.

The radicality of wound debridement is an important feature of the surgical treatment of pressure sores. Several methods such as injection of methylene blue or hydrogen peroxide have been proposed to facilitate and optimise the surgical debridement technique, but none of them proved to be sufficient. We present an innovative modification of the pseudo-tumour technique consisting in the injection of fluid silicone. Vulcanization of the silicone leads to pressure-sore moulding, permitting a more radical and sterile excision. In a series of 10 paraplegic patients presenting with ischial pressure sores, silicone moulding was used to facilitate debridement. Radical en bloc debridement was achieved in all patients. After a minimal follow-up of 2 years, no complications and recurrences occurred. A three-dimensional (3D) analysis of the silicone prints objectified the pyramidal shape of ischial pressure sores. Our study showed that complete resection without capsular lesion can be easily achieved. Further, it allows the surgeon to analyse the shape and size of the resected defect, which might be helpful to select the appropriate defect coverage technique.

A comparative study of two methods of surgical treatment for painful neuroma.

Painful neuromas may follow traumatic nerve injury. We carried out a double-blind controlled trial in which patients with a painful neuroma of the lower limb (n = 20) were randomly assigned to treatment by resection of the neuroma and translocation of the proximal nerve stump into either muscle tissue or an adjacent subcutaneous vein. Translocation into a vein led to reduced intensity of pain as assessed by visual analogue scale (5.8 (SD 2.7) vs 3.8 (SD 2.4); p < 0.01), and improved sensory, affective and evaluative dimensions of pain as assessed by the McGill pain score (33 (SD 18) vs 14 (SD 12); p < 0.01). This was associated with an increased level of activity (p < 0.01) and improved function (p < 0.01). Transposition of the nerve stump into an adjacent vein should be preferred to relocation into muscle.

Neurocutaneous sural flap in paraplegic patients.

Neurocutaneous flaps have been demonstrated to be a reliable option in different groups of patients but it remains unclear if distally-based sural flaps can be safely used in paraplegic patients because they suffer from significant nervous system alterations. The aim of this proof-of-concept study is to demonstrate that these flaps are reliable in paraplegic patients. We prospectively analysed a group (n=6) of paraplegic patients who underwent reversed sural flap surgery for ulcers on the lateral malleolus. Measurement of area and photographic documentation techniques have been employed to quantify the defect area. Sural nerve biopsies have been analysed histologically with several different staining techniques to assess the neurovascular network and the myelinisation of the nerve. The patients showed uneventful wound healing, except one case that suffered a partial flap necrosis that healed by secondary intention. Histologic analysis revealed an intact neurovascular network and myelinated nerve fibres. In this small series of paraplegic patients that underwent a distally-based sural flap, the complication rate was low, with only one case of superficial partial necrosis demonstrating the reliability and safety of the flap in this subset of patients. Histologic evaluation of sural nerve biopsies revealed an almost normal morphology. A possible explanation of this phenomenon is that the dorsal root ganglia remain intact in paraplegic patients and can preserve neural characteristics in the peripheral sensory nerve system.

An old dream revitalised: preconditioning strategies to protect surgical flaps from critical ischaemia and ischaemia-reperfusion injury.

The prevention of ischaemia and the adequate restitution of blood flow to ischaemic tissue are pivotal to halt the progression of cellular injury associated with decreased oxygen and nutrient supply. Accordingly, the search for novel strategies which aim at preventing ischaemia-reperfusion-induced tissue damage is still of major interest in flap surgery. Preconditioning represents an elegant approach to render the tissue more resistant against deleterious ischaemic insults. For many decades, 'surgical delay' has been the standard method of tissue preconditioning. During the last 10 years, ischaemic preconditioning was added to the repertoire of plastic surgeons to protect flaps from ischaemic necrosis. The invasiveness and expenditure of time of these procedures, however, have always been major drawbacks, hindering a wide distribution in clinical practice. Consequently, the motivation has all along been to further refine and simplify protective strategies. Recent experimental studies have now shown that efficient protection from ischaemic necrosis can also be achieved by remote preconditioning or pretreatment with chemical agents and growth factors, which mimic the action of surgical delay and ischaemic preconditioning. In addition, the local application of unspecific stressors, including both heating and cooling, have been shown to effectively improve flap microcirculation and, thus, tissue survival. In view of successful translational research, it is now time that the efficacy of these novel preconditioning procedures is proven in prospective randomised clinical trials.

Effective treatment of permanent tattoos with combustible particles due to blast injuries with a V-shaped device.

Permanent tattooing due to blast injuries is a rare condition. Treatment with various different methods often yields unsatisfactory results. An innovative way to remove permanent traumatic tattoos is presented. A normal curettage blade is simply compressed with a pincer in order to create the new device. This V-shaped blade was used for surgical excision of the particles. No suture material or special dressing was used. Four patients with multiple explosive tattoos on the face were treated with the V-shaped knife. Due to the ease and speed of this method up to 300 particles were removed in one session. Histological analysis of the tissue samples showed deep dermal and subcutaneous particle location. At follow-up transient hypopigmentation but only minimal scarring was seen. Patients suffered less from itching, a chief complaint preoperatively, and aesthetic appearance of the facial skin was improved. In conclusion, treatment of traumatic tattoos with the V-shaped knife is effective, results in minimal scaring and restores the natural colour of the skin because the particle is completely removed. It is a promising method for treating multiple deep skin inclusions.

Hand rub consumption and hand hygiene compliance are not indicators of pathogen transmission in intensive care units.

The objective of this study was to investigate whether nosocomial infection (NI) rates, hand hygiene compliance rates and the amount of alcohol-based hand rub used for hand disinfection are useful indicators of pathogen transmission in intensive care units (ICUs), and whether they could be helpful in identifying infection control problems. All isolates of 10 of the most frequent pathogens from patients who were hospitalized in an ICU for >48 h were genotyped to identify transmission episodes in five ICUs. The incidence of transmission was correlated with hand hygiene compliance, hand rub consumption and NI rates. The incidence of transmission episodes varied between 2.8 and 6.8 in the five ICUs. The NI rate was 8.6-22.5 per 1000 patient-days, hand hygiene compliance was 30-47% and hand rub consumption was 57-102 L per 1000 patient-days. There was no correlation between the incidence of transmission episodes and hand rub consumption or hand hygiene compliance. The correlation between transmission rates and NI rates was 0.4 (P = 0.5), and with the exclusion of one ICU, it was 1 (P < 0.01). The incidence of NI is a relatively good indicator for the identification of pathogen transmissions, but hand rub consumption and hand hygiene compliance, at least with the relatively low level of compliance found in this study, are not indicators of pathogen transmission.

Use of 2% 2-phenoxyethanol and 0.1% octenidine as antiseptic in premature newborn infants of 23-26 weeks gestation.

In preterm newborn infants, topical iodine-containing antiseptics disturb thyroid hormone regulation while alcohol-based disinfectants may cause local burns. We therefore investigated the use of an aqueous solution containing 0.1% octenidine and 2% 2-phenoxyethanol for skin disinfection during the first seven days of life in premature newborns with a gestational age <27 weeks who were consecutively admitted to our level III neonatal intensive care unit between November 1, 2000 and December 31, 2001 (N=24). In boys. (N=13) the renal excretion of absorbed 2-phenoxyethanol and its metabolite 2-phenoxyacetic acid was quantitated by high-pressure liquid chromatography. In the most immature newborn (gestational age 23 6/7 weeks), a transient erythematous reaction was observed following application of the octenidine/phenoxyethanol solution prior to umbilical vessel catheterization. No other local reactions were observed. The urinary concentration of 2-phenoxyethanol was <2 ppm in all samples, while urinary 2-phenoxyacetic acid concentrations reached 5-95 ppm (median 24 ppm). One infant had a culture-proven septicaemia (Bacillus species) during the first seven days of life. We conclude that, in contrast to alcohol-based antiseptics, an aqueous solution of 0.1% octenidine and 2-phenoxyethanol does not cause major skin damage in premature newborn infants <27 weeks' gestation. 2-Phenoxyethanol is readily absorbed by the newborn's skin but apparently undergoes extensive oxidative metabolization to 2-phenoxyacetic acid.

Radical sternectomy and primary musculocutaneous flap reconstruction to control sternal osteitis.

OBJECTIVE: Sternal osteitis after median sternotomy is associated with considerable morbidity and mortality. The use of muscle and omentum flaps has been proved as valid adjunct to combat these severe infections. In this study we present our experience with a more radical approach. METHODS: Sternectomy consisted of the resection of the entire sternum, including the costochondral arches and the sternoclavicular joints, and was followed by the repair of the defect with musculocutaneous flaps without any restabilization of the thoracic wall. Thirteen patients received a vertical rectus abdominis musculocutaneous flap, 14 patients received a pedicled latissimus dorsi musculocutaneous flap, and 12 patients received a free latissimus dorsi musculocutaneous flap (total of 40 flaps in 39 patients of 66 patients who required surgical revision for sternal osteitis of 6078 total patients with sternotomies). RESULTS: Two patients died within 30 days after the operation (early mortality of 5.1%); however, they did not die of sternal infection, which was cured without any recurrence in all cases. Seventeen patients (44%) required secondary, mostly minor operations for local complications. Despite some paradoxic chest movements, the patient satisfaction rating was unanimously high at the long-term follow-up (0.4 to 8.5 years, median 2.3 years). The short- and long-term complication rates were similar in the three groups. CONCLUSION: We conclude that radical sternectomy and immediate musculocutaneous flap repair provided definitive control of sternal infection in even the most severe cases, thus reducing infection-related mortality. The trade-off was a substantial rate of local complications; however, these did not cause any relevant morbidity.
