- To improve the shape of the cleft lip nose preoperatively, we have developed the nasal alar elevator. This has been used routinely since 1996 on all our cleft lip patients who have an asymmetrical nose, from the first week after birth until the date of primary lip surgery. We present our 11-year-long experience of using the device on patients born with complete, unilateral cleft lip. In this study 56 children, born between 1996 and 2006 inclusive, with complete unilateral cleft lip, had preoperative treatment with the elevator. During this 11-year period, continuous evaluation during the preoperative period, and its effects on the cleft lip nose, were evaluated, both preoperatively and postoperatively. Our results show that the preoperative use of the device has led to less need for primary nasal surgery. Instead of having to have a primary rhinoplasty (McComb) together with a lip plasty, as a routine, now only about 30% of the patients need primary surgical correction of the nose. If nasal correction is needed, a rather limited undermining of skin over the ala on the cleft side will often be sufficient. The use of a nasal elevator reduces both the length and the extent of the primary intervention, without compromising the final result.

Tidskriftsartikel (refereegranskat)abstract
- We aimed to evaluate a new technique for intraoral expansion of soft tissue with a self-inflatable expander in rabbits. We placed a self-inflatable soft tissue expander bilaterally in eight rabbits under the periosteum of the mandible through an extraoral approach. The expander was left to self-inflate for two weeks, after which the animals were killed and specimens collected for histological examination. The self-inflatable soft tissue expanders expanded the periosteum. There were no dehiscences or infections. Histological observations showed no signs of any inflammatory reaction and there was no evidence of bony resorption. New bone had formed at the edges of the expanded periosteum. In the control area no new bone had formed. The osmotic soft tissue expander model for intraoral soft tissue and periosteal expansion suggests a promising way of creating a surplus of soft tissue that can be used to cover bone grafts.

Tidskriftsartikel (refereegranskat)abstract
- Four patients with no history of trauma presented with lateral arm pain, local tenderness, and a tingling sensation at the distal end of the arm when the radial nerve was percussed in the mid-third of the upper arm (Tinel's sign), but no clinical or subjective signs of muscular weakness. They were treated by decompression of the radial nerve in the fibrous canal proximal to the lateral intermuscular septum. Three of the patients had a complete or pronounced reduction in pain, while the fourth had only a slight improvement. Non-traumatic radial nerve entrapment in the upper arm may be the cause of lateral arm pain without clinical signs of muscular weakness.

Tidskriftsartikel (refereegranskat)abstract
- An axillary brachial plexus nerve block by a transarterial approach is commonly used to achieve regional anaesthesia for hand surgery. We designed a retrospective study to evaluate efficacy and safety of the technique for acute and elective operations. Anaesthetic records of 189 of all 5520 patients (1996-2000) who had axillary brachial plexus blocks for hand surgery were reviewed, and results compared with complications recorded in the anaesthetic register and in the hand surgery records. Successful axillary block was achieved in 5128/5520 (93%) of patients, according to anaesthetic charts, and primarily in 157/189 (83%), and after supplementation in 171/189 (90%), according to anaesthetic records. Four patients had a toxic drug reaction or axillary haematoma with a transient neurological deficit. Medical complications were recorded in the anaesthetic register in less than 0.7% of axillary brachial plexus procedures. Axillary brachial plexus block by a transarterial approach is effective and safe in hand surgery.

Bioartificial nerve graft for bridging extended nerve defects in rat sciatic nerve based on resorbable guiding filaments
- 2000

Tidskriftsartikel (refereegranskat)abstract
- A long defect (15 mm) in rat sciatic nerve was repaired with a bioartificial nerve graft composed of a silicone tube and seven synthetic filaments of five types (polyamide, catgut, polydioxanone, and two types of polyglactin, normal and quickly-absorbed) inserted longitudinally into the tube. In all cases in which filaments were used a regenerating bridge was obtained in the tube after three months in contrast to empty silicone tubes, in which no structure was observed. There was a 6% ~ 46% recovery of isometric muscle contractility of the anterior tibial and gastrocnemius muscles with positive pinch reflex test in most cases. Myelinated axons were seen in the regenerating tissue between the filaments but not directly in contact with them, and there were varying numbers of macrophages close to the filaments. Silicone tubes with filaments, regardless of type of filament, induced nerve tissue to regenerate and resulted in functional recovery through a 15 mm nerve gap not achieved with empty tubes. Nerve promoting factors may be applied to the filaments and the model is a valuable tool for further development of artificial nerve grafts.

Implantation of Schwann cells in rat tendon autografts as a model for peripheral nerve repair: Long term effects on functional recovery
- 2008
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 42:6, s. 281-285

Tidskriftsartikel (refereegranskat)abstract
- Cultured Schwann cells in tendon autografts for nerve repair improve the early phase of nerve regeneration in rat sciatic nerves as judged by the rate of axonal outgrowth. We tested the long-term effects on functional recovery using measurements of muscle force, the number of axons and myelination, using morphometry. In addition, we recorded wet weight of the gastrocnemius muscle. Schwann cell cultures were prepared from predegenerated nerves. Ten and 15mm defects in rat sciatic nerves were bridged using bilateral tendon autografts with Schwann cell-seeded tendon autografts on one side, and untreated tendon autografts on the other. Animals were evaluated at six and 12 weeks, respectively. At six weeks, myelination, as judged by G-ratio (ratio of axonal diameter to diameter of nerve fibres), was significantly increased in tendon autografts pretreated with Schwann cells in 10mm defects. No such difference was seen in the 15 mmdefects. We found no difference in functional recovery, other morphometric variables, or muscle weight between the two grafts. We conclude that early effects on nerve regeneration using transplantation of cultured Schwann cells in rat sciatic nerves are temporary. Other strategies are necessary to obtain lasting effects on functional recovery.

Adult skeletal profile in isolated cleft palate: a comparison of the von Langenbeck and Wardill procedures for primary repair of the palate
- 2001
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 35:4, s. 387-397
-
Tidskriftsartikel (refereegranskat)abstract
- Sixty-four adult patients operated on for isolated cleft palate were evaluated with regard to facial skeletal morphology using conventional radio-cephalometry. Dental occlusion was assessed clinically. Forty-two had had a von Langenbeck repair at the age of 7 months and 22 a Wardill repair at 18 months. The mean error of the method was 0.7 degree for angular, and 0.9 mm for linear, measurements. The group with clefts had less maxillary prognathism (s-n-ss), more maxillary inclination (NSL/NL), more retroclined lower incisors (ILI/ML), and shorter total and upper facial heights (n-gn, n-sp) compared with the reference group. Multiple regression analysis was used to evaluate differences between the two treatment regimens. Explanatory variables in addition to surgical technique were sex, severity of cleft, and presence of a velopharyngeal flap. Only one variable, lower incisor inclination (ILI/ML), was different for the two regimens. Ten (24%) in the von Langenbeck group had a lateral cross-bite compared with one (5%) in the Wardill group. Other variables in a multivariate regression analysis were affected by sex and severity of cleft to various degrees. This study showed no obvious differences in facial skeletal morphology that could be attributed to surgical technique. Factors other than technique, including sex, age, and severity of cleft merit attention.

Clinical examination compared with morphometry of digital photographs for evaluation of repaired cleft lips
- 1998

Tidskriftsartikel (refereegranskat)abstract
- Twenty-four adult patients who had been operated on as infants for isolated cleft lip underwent clinical examination combined with photographic documentation using a digital camera. The same predetermined protocol comprising 20 variables describing nasolabial appearance was used for both the clinical examination and the computerised evaluation of the images. The correlation between the two methods is described in the present study. The results obtained with the two methods agreed closely. For metric variables the mean coefficient of correlation was 0.73 and when all measurements were combined, it reached 0.98. Likewise, discrete variables showed a close correlation, with a mean kappa value of 0.72. Variables related to muscular dynamics of the lip can for obvious reasons not be judged from photographs. However, the computerised photographic evaluation was able to detect more precisely even minor angular deviations of the nose and to measure areas such as the areas of the nostrils. We conclude that morphometry of digital photographs is a new valuable clinical tool for the assessment of the nasolabial appearance in patients with cleft lip and palate.

Millard repair of unilateral isolated cleft lip: a 25-year follow-up

Tidskriftsartikel (refereegranskat)abstract
- Twenty-five patients with isolated unilateral cleft lip took part in a follow-up study at a mean age of 28.6 years. All had had a primary, Millard lip repair, at a mean age of 4.6 months. In 20 patients, at least one secondary correction had been undertaken during adolescence. The overall long-term outcome was thought to be good, leaving a fairly inconspicuous fine lip scar and acceptable nose configuration. In half the patients, however, the lip was slightly elongated and the nostrils were still asymmetrical. These findings concurred with the patients' subjective assessments, which showed that appearance of the lip and nose were rated good by 20 (80%) and 16 (64%), respectively. The findings of this study provide a baseline for future evaluation of the results achieved with lip closure by Johanson's technique.

Tidskriftsartikel (refereegranskat)abstract
- As digital photography is being increasingly used in clinical medicine, we devised a software program for 'on screen' image analysis, which allows distance, angle, and area to be measured. In this study, 30 photos were evaluated by 10 observers, so 3000 observations were used to test the reproducibility of the measurements. The results showed excellent reproducibility within observer, between observers, and between photographs. The coefficient of variation (CV) ranged from 0 to 1.3% for distance, from 0.6 to 2.3% for angle, and from 1.5 to 7.7% for area. The system could be particularly useful for assessing patients with cleft lip and palate.

Von Langenbeck or Wardill procedures for primary palatal repair in patients with isolated cleft palate--speech results
- 2000

Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 34:1, s. 27-32

Tidskriftsartikel (refereegranskat)abstract
- Sixty-six patients operated on for isolated cleft palate were evaluated as adults, and their speech was assessed clinically. Forty-four had undergone a von Langenbeck repair at the age of 7 months and 22 a Wardill repair at the age of 18 months. Speech was judged subjectively by the patients themselves, and perceptual assessment was made by three speech pathologists. The remaining speech problems, mainly hypernasality, were moderate or severe in 7 (16%) of the patients in the von Langenbeck group, and in 7 (32%) in the Wardill group. On the other hand, the patients in the Wardill group had fewer fistulas closed, and fewer velopharyngoplasties. There were no significant differences between the two methods regarding speech in adulthood. The Wardill method produced significantly more scar tissue clinically, which carries the potential risk of inhibition of facial growth. The present speech results will therefore be weighed against the outcome of maxillofacial growth for these patients.

Germline mutation screening of the Saethre-Chotzen-associated genes TWIST1 and FGFR3 in families with BRCA1/2-negative breast cancer

Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Taylor & Francis. - 0284-4311 .- 1651-2073. ; 43:5, s. 251-255

Tidskriftsartikel (refereegranskat)abstract
- Saethre-Chotzen syndrome is one of the most common craniosynostosis syndromes. It is an autosomal dominantly inherited disorder with variable expression that is caused by germline mutations in the TWIST1 gene or more rarely in the FGFR2 or FGFR3 genes. We have previously reported that patients with Saethre-Chotzen syndrome have an increased risk of developing breast cancer. Here we have analysed a cohort of 26 women with BRCA1/2-negative hereditary breast cancer to study whether a proportion of these families might have mutations in Saethre-Chotzen-associated genes. DNA sequence analysis of TWIST1 showed no pathogenic mutations in the coding sequence in any of the 26 patients. MLPA (multiplex ligation-dependent probe amplification)-analysis also showed no alterations in copy numbers in any of the craniofacial disorder genes MSX2, ALX4, RUNX2, EFNB1, TWIST1, FGFR1, FGFR2,FGFR3, or FGFR4. Taken together, our findings indicate that mutations in Saethre-Chotzen-associated genes are uncommon or absent in BRCA1/2-negative patients with hereditary breast cancer.

- Functional magnetic resonance imaging (fMRI) was used to study how a replanted hand regained its cortical territory parallel to recovery. The cortical response to sensory stimulation shifts from an ipsilateral to a bilateral pattern, and then to a predominantly contralateral activation. The cortical response to motor stimulation was normal from the first investigation.

Tidskriftsartikel (refereegranskat)abstract
- We describe two patients with uncommon causes of iatrogenic injuries and review the anatomy, presentation, possibilities of repair, and results. The incidence of such nerve injuries during lymph node biopsies is 3%-10%, but the diagnosis is often delayed. Symptoms are shoulder pain and inability to abduct the arm beyond the horizontal plane. Surgical repair may improve function and pain and should be performed early, preferably within six months, but prevention of nerve injury is most important.

Acutely-dissociated Schwann cells used in tendon autografts for bridging nerve defects in rats: a new principle for tissue engineering in nerve reconstruction
- 2005
-
Ingår i: Scand J Plast Reconstr Surg Hand Surg. - 0284-4311. ; 39:6, s. 321-5
-
Tidskriftsartikel (refereegranskat)abstract
- A new method of acute dissociation of Schwann cells was used to study the effect of addition of such cells to a tendon autograft--a recently-described graft material--on peripheral nerve regeneration in rats. Autologous Schwann cells were obtained from enzymatic dissociation of predegenerated nerves. The tendon autografts were supplied with Schwann cells through brief in vitro coincubation. Schwann cell-free tendon autografts were used as controls. Axonal outgrowth was measured immunohistochemically after four, seven, and 10 days. At seven days, outgrowth was significantly longer in the pretreated autografts. The use of acutely-dissociated Schwann cells is a new approach to tissue engineering in nerve reconstruction, and may abolish the need for time-consuming culture of Schwann cells.

Complete reduction of lymphoedema of the arm by liposuction after breast cancer
- 1997
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - 0284-4311. ; 31:2, s. 137-143
-
Tidskriftsartikel (refereegranskat)abstract
- The incidence of lymphoedema of the arm after mastectomy ranges between 8% and 38%, and it is an appreciable problem from both functional and social aspects. Conservative and previous surgical regimens have not been completely successful. In the light of these experiences, liposuction clearly constitutes an interesting new surgical approach, which is potentially capable of effecting predictable and reliable improvements in patients with lymphoedema. Twenty eight women with lymphoedema of the arm after breast cancer were consecutively treated by liposuction. Limb compression with a compression garment was instituted immediately after operation. All patients had been given radiotherapy after the operation for breast cancer. Mean preoperative volume of oedema was 1845 ml (range 570-3915), and mean volume of aspirate was 2250 ml (range 1000-3850); volume of aspirate correlated linearly with the volume of preoperative oedema. There were no major surgical complications, but blood transfusion was necessary in eight patients whose volume of aspirate exceeded 2000 ml. After 12 months (n = 24), an average reduction in volume of oedema of 106% was found. Such a normalisation can be expected in patients with oedema that amounts to about 2500 ml. Although the oedema cannot be completely removed in more severe cases, substantial reduction is beneficial from both functional and cosmetic aspects. We conclude that liposuction is safe and effective for reducing lymphoedema of the arm after operations for breast cancer. In a one-stage procedure, oedematous and hypertrophic fat tissue can be removed with an excellent clinical outcome.

Tidskriftsartikel (refereegranskat)abstract
- Despite refinements in surgical technique, including bone grafting and sophisticated prosthetic reconstructions, there are limitations to what can be achieved with bone-anchored fixed prostheses in patients with advanced atrophy of the maxillae. A new approach was suggested by a long-term study on onlay bone grafting and simultaneous placement of a fixture based on a new design: the zygoma fixture, and the aim of this study was to assess its potential. Twenty-eight consecutive patients with severely resorbed edentulous maxillae were included, 13 of whom had previously had multiple fixture surgery in the jawbone that had failed. A total of 52 zygoma fixtures and 106 conventional fixtures were installed. Bone grafting was deemed necessary in 17 patients. All patients have been followed for at least five years, and nine for up to 10 years. All patients were followed up with clinical and radiographic examinations, and in some cases rhinoscopy and sinoscopy as well. Three zygoma fixtures failed; two at the time of connection of the abutment and the third after six years. Of the conventional fixtures placed at the time of the zygoma fixture, 29 (27%) were lost. The overall prosthetic rehabilitation rate was 96% after at least five years of function. There were no signs of inflammatory reaction in the surrounding antral mucosa. Four patients with recurrent sinusitis recovered after inferior meatal antrostomy. To conclude, the zygoma fixture seems to be a valuable addition to our repertoire in the management of the compromised maxilla.

Biomechanical and morphological studies on osseointegration in immunological arthritis in rabbits.

Tidskriftsartikel (refereegranskat)abstract
- The biomechanics and morphology of the interface between bone tissue and threaded, commercially pure titanium implants were studied i an experimental model of monoarticular arthritis in New Zealand white rabbits (n = 8). Two of the eight rabbits died before evaluation. Immunisation with bovine serum albumin (BSA) and repeated intra-articular injections with BSA in one knee joint elicited an immune response and clinical signs of inflammation. The opposite joint was injected with saline. Three implants were inserted intra-articularly in the lateral femoral condyle in each joint. After a period of six weeks the stability of two of the three implants was evaluated by pull-out and torsion tests using a standardised biomechanical model. The rabbits were killed by perfusion fixation, and the implants and surrounding tissue were retrieved en bloc for histological analysis. The amount of bone, the degree of bone apposition, and the biomechanical evaluation showed that the absolute mechanical capacity of anchorage was not significantly reduced on the arthritic side compared with the control knees. These results indicate that it might be possible to obtain osseointegration in juxta-articular bone despite local joint inflammation.

Our experience using the vertical rectus abdominis muscle flap for reconstruction in 12 patients with dehiscence of a median sternotomy wound and mediastinitis

Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 0284-4311 .- 1651-2073. ; 37:5, s. 266-271
-
Tidskriftsartikel (refereegranskat)abstract
- The vertical rectus abdominis (VRAM) flap has been used for reconstruction of sternal defects, particularly in the interior third, since it was first described 20 years ago. We describe 12 patients with mediastinitis or chronic sternal osteomyelitis after sternotomy treated between 1994 and 1997, nine performed at the Royal Hospitals Trust, London. Sternal osteomyelitis and mediastinitis after median sternotomy is an uncommon (0.4%-8.4%) but often fatal condition. Vascularised pedicles are the treatment of choice, and VRAM flaps were used in all cases. We report good long-term outcome with a follow up of 2-5 years, and no long-term morbidity relating to the VRAM reconstruction. We had only one partial failure of a flap. The operations were largely done in hospitals away from the plastic surgical unit in extremely sick patients, which illustrates the importance of multidisciplinary management to reduce hospital stay, mortality, and morbidity. We argue that early involvement of plastic surgical specialists in the treatment of sternal dehiscence is essential to ensure a successful outcome.

Tissue response to silicone tubes used to repair human median and ulnar nerves

Tidskriftsartikel (refereegranskat)abstract
- Silicone tubes of appropriate sizes were used to enclose the injured zone of transsected ulnar and median nerves in the human forearm as an alternative to conventional microsurgical repair of the nerve trunk. A gap measuring 3-5 mm was left intentionally between the nerve ends inside the tube. The clinical early results from a prospective randomised study that compared these two principles have recently been presented. Seven patients (five men and two women), aged 15-49 years (median 20) were reexplored 12-44 months (median 22) after the initial procedure because of local discomfort from the tube in four patients. There was a new nerve structure bridging the former gap and in most cases it was impossible to distinguish the site of the injury. In all cases there was a thin capsule around the silicone tube that microscopically consisted of connective tissue with thin walls and no signs of inflammation granuloma or macrophages (n = 4), while in two cases a mild foreign body reaction was seen at a single site (n = 1) or at patchy areas (n = 1). These results indicate that after more than one year there is a limited tissue reaction around silicone tubes used to repair median and ulnar nerves in humans.

- Two neonates with proximal dorsal swelling and skin necrosis had median, ulnar, and particularly radial nerve palsies after birth, which was interpreted as compartment syndrome in the forearm. The swelling in case 1 disappeared, the skin lesion in case 2 healed, and the functions of nerves recovered almost completely in both cases, although the forearm and hand in the second patient were shorter and thinner than the contralateral side.

- Partial and complete injured median and ulnar nerves caused by fractures of the radius and ulna, respectively, in which the symptoms of nervous injury were induced at the time of fracture are reported. In cases with complete loss of nervous function early exploration should be considered at the time of reposition or plating of the fractured bones, or both, and in patients in whom nervous dysfunction occurs after the operation.

- Gore-tex chambers were used to bridge a 6 mm gap between the proximal and distal nerve stumps of a rat sciatic nerve. The wall structure of these chambers is characterized by "nodes" interconnected by smaller fibrils. Chambers with internodal distances of 5, 10 and 30 microns were used. Some 30 microns chambers were coated from the outside with Gore-tex (0.2 micron internodal distance) and others were coated from the inside. Regeneration after 12 weeks, as evidenced by muscle action potential recordings and light microscopy, was successful regardless of what type of chamber had been used. The organization of the nerve structure varied among different chamber types. A well organized coaxial nerve structure with myelinated axons was observed if inner-coated chambers were used. In chambers that were not coated or in outer-coated chambers tissue completely filled the chambers, and myelinated axons were arranged in mini-fascicles surrounded by loose connective tissue.

Different effect on axonal outgrowth of application of nonabsorbable or absorbable tubes around a nerve repair
- 2001

Tidskriftsartikel (refereegranskat)abstract
- We studied regeneration distance of rat sciatic nerve, with the sensory pinch reflex test and immunocytochemical staining for neurofilaments, four to 21 days after transsection, repair, and enclosure of the repair site in either a non-absorbable silicone tube or an absorbable polyglycolic acid (PGA) tube. The size of both tube-types was carefully selected so that they did not compress the repaired nerve. The opposite nerve was repaired and not inserted in a tube (control). The regeneration distances in repaired nerves enclosed in silicone tube were significantly longer than the control side at all time points, a result not seen when PGA tube was used. The number of proliferating non-neuronal cells (incorporation of 5-bromodeoxyuridine (BrdU)) was studied just proximal to the site of nerve repair after six days. Numerous stained cells were seen, but there where no significant differences between the groups. We conclude that outgrowth of sensory axons after transsection and repair of rat sciatic nerve with sutures can be increased by enclosing the site of repair in a silicone tube but not in a PGA tube. The effect is probably not related to the number of proliferative non-neuronal cells.

Speech results in adult Swedish patients born with bilateral complete cleft lip and palate.

Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 43:4, s. 207-213

Tidskriftsartikel (refereegranskat)abstract
- Thirty-six adult patients (26 men and 10 women) who had been operated on for bilateral complete cleft lip and palate (BCLP) were evaluated with regard to long-term follow-up consisting of clinical investigation, perceptual speech analysis, and self-estimation of quality of speech. Twenty-six had had a von Langenbeck repair at the age of 14 months (L-14 group), and 10 a Wardill repair at the age of 18 months (W-18 group). Statistical comparisons between the groups were made by univariate and multiple logistic regression analyses. Both groups had a large percentage of hypernasality despite a high incidence of velopharyngeal flaps in both. There were no significant differences between the groups regarding any of the analysed speech variables. The outcomes of hypernasality, nasal escape, velopharyngeal friction sounds, hyponasality, and general impression indicate, however, a slightly better result for the L-14 group.

Tidskriftsartikel (refereegranskat)abstract
- Sixty-one adult patients (34 men and 27 women) who were operated on for unilateral complete cleft lip and palate (UCLP) were followed up from 1996-2001 by clinical investigation, perceptual speech analysis, and self-estimation of quality of speech. Thirty-four had had a von Langenbeck repair at the age of 8 months (L-8 group), and 27 a Wardill repair at the age of 18 months (W-18 group). Statistical comparisons were made by univariate and multiple logistic regression analyses. The L-8 group had a slightly better general outcome but at the expense of a greater incidence of velopharyngeal flaps. There was no significant difference in hypernasality, being 7/34 (21%) of the patients in the L-8 group, compared with 9/27 (33%) in the W-18 group. Compared with findings reported previously of patients with isolated cleft palate (CP) who were treated and investigated under the same circumstances, the speech outcome in the group with UCLP was found to be significantly better.
