Determination of the optimal frequency of injection of triamcinolone: monitoring change in volume of keloid lesions following injection of 40 mg of triamcinolone

Background

Different dosage protocols may be advocated by different clinicians for the same keloid lesion. The aim of this study was to determine the optimal frequency of injection of triamcinolone for the purpose of reducing the size of keloid, by monitoring volume change in lesions.

Methods

Volume of all lesions was measured, and 40 mg of triamcinolone was injected once. Lesion volume was thereafter monitored weekly for 6 weeks.

Results

Mean pretreatment volume was 6.4 ml. Following triamcinolone injection, mean lesion volume became 5.1, 3.7, 3.6, and 3.6 ml at 1, 2, 3, and 4 weeks postinjection, respectively. The mean lesion volume was 3.7 and 3.9 ml at 5 and 6 weeks postinjection. Mean lesion volume was 1.29 ml lower at 1 week than at pretreatment stage (SD?±?0.8797), 1.35 ml lower in volume at 2 weeks than 1 week (SD?±?1.0386), and 0.138 ml lower in volume at 3 weeks than 2 weeks (SD?±?0.159). Mean lesion volume was 0.0250 ml lower at 4 weeks than at 3 weeks (SD?±?0.3215), 0.1000 ml greater in volume at 5 weeks than 4 weeks (SD?±?0.1713), and 0.2000 ml greater in volume at 3 weeks than 2 weeks (SD?±?0.0418). There is a statistically significant difference between the mean volume at 1 week postinjection and that at pretreatment stage, between 2 and 1 week, and between 3 and 2 weeks (p?≤?0.05). Reduction in volume was found to be most profound and statistically significant within the first 2 weeks postinjection.

Conclusions

This study finds that the optimal frequency of intralesional injection of triamcinolone involves a 2-week injection interval.Level of Evidence: Level IV, therapeutic study

     

Critical choices in cleft surgery: 18-year single-surgeon retrospective review of 900 cases

Background

Multidisciplinary management of orofacial clefts may lead to a successful treatment outcome. However, it is quite usual that lack of long-term treatment planning and collaboration among various specialists and lack of standardized surgical protocols result in poor esthetic and functional treatment outcomes. This article aims to hypothesize some critical determinants of outcome in cleft surgery.

Methods

Throughout a period of 18 years, 900 patients with different clinical types of congenital cleft anomaly were subject to primary repair of cleft lip, nose, and palate by single surgeon using various procedures, including preoperative nasoalveolar molding, two-stage and one-stage repair of complete cleft lip and palate, two-flap and one-flap palatoplasty, open tip rhinoplasty, and postoperative nasal molding.

Results

Clinical results of preoperative nasoalveolar molding and surgical repair of lip, nose, and palate were satisfactory for most patients, parents, and surgeon panel.

Conclusions

Treatment based on the individual patient’s facial assets and deficits must be the controlling factor in designing therapy. The essential key to successful management of clefts is to figure out the three-dimensional dynamics that govern the deformity and to recognize a fourth dimension for time along these dynamics in order to envision how a small difference in the position of a single suture during the first surgery can bring about a giant deformity upon completion of facial growth, hence the crucial role of the first surgery and its related concepts, techniques, and tactics in dictating the final outcome of the case.Level of Evidence: Level IV, therapeutic study.

     

Computer-assisted analysis contour lines of aesthetic unit for the assessment of lip augmentation

Background

Lip augmentation and changing contour lines have become more popular ways of improving the appearance. However, validated measures of lip fullness for quantification of outcomes are needed; ethnic background and personal goals can optimise outcomes while tailoring lip enhancement treatment to each individual’s anatomy. The aim of this study is to analyse the morphological features of the lip in detail and to clarify the objective parameters in related with the subjective ones regarding the lip augmentation and lip reconstruction.

Methods

Standard photographs of the lips of 200 young Anatolian adults were calculated with linear and angular components. The features of the lower third of the face were analysed with the software program. Linear analyses (heights of the upper lip, the upper vermilion, the lower lip height, the lower vermillion and the chin height) and angular analyses (the upper lip, the lower lip, the apex and Cupid’s bow angles) were measured as reference points. The lip shape was classified into five groups: thin, very thin, medium, full and very full.

Results

The lower third of the face was divided into three segments (Sn–Sto, Sm–Me and Sto–Sm), and the largest portion of the lower face was occupied by the chin and the smallest by the lower lip height in both genders. The upper vermilion height was 8.07?±?1.8 mm in males and 7.08?±?1.5 mm in females. The lower vermilion height was 10.1?±?2.4 mm in males and 9.7?±?1.9 mm in females. The upper lip angle was calculated as 30.3?±?9.6° in males and 24.2?±?6.2°mm in females. The lower lip angle was calculated as 38.3?±?9.7° in males and 36.5?±?6.4° in females. Meanwhile, the angular measurements of Cupid’s bow (i.e., the apex and the central angle of Cupid’s bow) were smaller in men than in women. When the lip was analyzed, the medium and full types in upper and lower lips accounted for substantial fractions in men, whereas medium and thin types were predominant also in women.

Conclusions

With the help of certain software, this research has made possible to define the best cosmetical redesign solution of lip construction and augmentation with a natural appearance for the patient.Level of Evidence: Level III, diagnostic study.

     

Bilateral autologous microtia reconstruction: a simultaneous two-stage approach

Background

Traditionally, for cases of bilateral autologous ear reconstruction, each side is addressed independently in discrete operative sessions. Herein, we describe our approach to bilateral microtia reconstruction, where each stage is performed simultaneously on both sides.

Methods

All patients who underwent autologous ear reconstruction by a single surgeon (NWB) from April 2006 to January 2012 were retrospectively reviewed. Reconstruction was realized as a two-stage procedure, with each stage performed simultaneously on both sides in bilateral cases. Patient demographics, operative details and incidences of peri- and post-operative complications were collected. A cost comparison of two-stage versus four-stage bilateral auricular reconstruction was completed.

Results

Among a total of 182 patients who underwent autologous ear reconstruction, 18 patients (male, 10, median age, 11.4 years) had simultaneous bilateral auricular correction. Based on estimates derived from unilateral reconstruction theatre times, simultaneous bilateral reconstruction resulted in a savings of 56 min for the first stage and 97 min for the second stage of reconstruction. Moreover, surgical times decreased as operative experience with auricular reconstruction was accrued. There was no increased incidence of peri- or post-operative complications noted. Based on cost estimates at our institution, bilateral reconstruction as a two-stage procedure resulted in a health care cost savings of £10448.16 ($16790.72 USD) per patient with bilateral microtia.

Conclusions

Simultaneous bilateral autologous ear reconstruction is a practicable cost-effective treatment strategy with notable aesthetic and personal benefit to the patient with no increased morbidity.Level of Evidence Level III, therapeutic study.

     

Gluteal muscle fibrosis with abduction contracture of the hip

Purpose

Gluteal muscle fibrosis with hip contracture is a rare condition and causes major disability; literature reports are sparse. The aim of this study is to present, for the first time in Iraq and the region, a case series of gluteal fibrosis and the results of surgical treatment.

Methods

Seven children—six boys and one girl—diagnosed as having gluteal muscle fibrosis with hip contracture, were investigated and treated by open surgical release of fibrotic bands and physiotherapy.

Results

All patients improved dramatically over the subsequent weeks, and were able to sit and squat in the normal position.

Conclusions

Gluteal muscle fibrosis with hip contracture is present in Iraq and more awareness is needed for early diagnosis. Surgical treatment provided excellent results. More studies are needed to delineate the aetiology of the condition.

     

Surgical result of plate osteosynthesis using a locking plate system through an anterior humeral approach for distal shaft fracture of the humerus that occurred during a throwing motion

Purpose

This paper analyzed outcomes of the osteosynthesis with a locking plate system for the fractures of the humerus in throwers using the anterior humeral approach.

Methods

Retrospective case series including 31 patients. Bone union was assessed through follow-up radiographs. Results of visual analogue scale (VAS) for pain, range of motion in the elbow joint, time of return to work, and the Mayo Elbow Performance Score (MEPS) were evaluated to determine functional outcomes. Direction and length of the fracture, the distal cortical length, the humeral diameter, and the total humeral length were measured as part of fracture configuration analysis.

Results

Mean patient age was 25.8 (range, 18–34) years. The follow-up average was 16.0 months (range, 12–23). Delayed union was observed in one (3.1 %) patient. Mean final VAS was 0.4 (range, 0–2), mean time of return to work was 18.2 weeks (range, 13–36), and mean MEPS was 96.3 (range, 88–100) points. All fractures showed a spiral configuration. Mean fracture length was 79.7 (95 % CI, 72.6-86.7) mm, and mean distal cortical length was 48.3 (95 % CI, 37.8-58.8) mm.

Conclusions

The results of the current study indicates that plate osteosynthesis using a locking plate system combined with interfragmentary lag screws through anterior humeral approach may be a favorable option for the surgical treatment of humeral shaft fractures in throwers.

     

Pelvic tilt compensates for increased acetabular anteversion

Purpose

Pelvic tilt determines functional orientation of the acetabulum. In this study, we investigated the interaction of pelvic tilt and functional acetabular anteversion (AA) in supine position.

Methods

Pelvic tilt and AA of 138 individuals were measured by computed tomography (CT). AA was calculated in relation to the anterior pelvic plane (APP) and relative to the table plane. We analysed these parameters for gender-specific and age-related differences.

Results

The mean pelvic tilt was -0.1?±?5.5°. Pelvic sagittal rotation displayed no gender nor age related differences. Females showed higher angles of AA compared with males (20.0° vs 17.2°, p?<?0.001; AA relative to the APP). Anterior tilting of the pelvis positively correlated with AA and individuals with high AA had a higher anterior pelvic tilt compared with those with low AA (p?<?0.0001; AA relative to the APP).

Conclusions

AA has to be calculated regarding pelvic sagittal rotation for correct acetabular orientation. Pelvic tilt is dependent on acetabular orientation and compensates for increased AA.

     

Short Bouts of Intensive Exercise During the Workday Have a Positive Effect on Neuro‐cognitive Performance

Beside its positive impact on physical health, exercise is indicated to positively affect cognitive performance based on a relocation of cortical activity. This study examined the influence of different types of breaks on cognitive performance and related cortical activity in office‐based employees. Breaks were filled with exercise, resting or a usual break and a control condition where employees continued working without any break. Cognitive performance was assessed using the d2‐R test and two commercially available cognitive tasks. Brain cortical activity was recorded using electroencephalography before and after breaks. Individual's mood was analysed using a profile of mood state. Results indicate a positive effect of a 3‐min boxing intervention on cognitive performance, mirrored by a decrease in prefrontal cortex activity. Although perceived psychological state was increased after the usual break, this is reflected in neither cortical activity nor cognitive performance. With respect to the fact that also bike activity resulted an increase in prefrontal alpha‐2 activity, a positive effect of exercise on neuro‐cognitive performance can be stated. Health and economic benefits may result from brief physical activity breaks and help to maintain workplace performance and job satisfaction. Copyright © 2015 John Wiley & Sons, Ltd.     

FGF 19 and Bile Acids Increase Following Roux-en-Y Gastric Bypass but Not After Medical Management in Patients with Type 2 Diabetes

Background

This study aims to quantify changes in fibroblast growth factor 19 (FGF19) and bile acids (BAs) in patients with uncontrolled type 2 diabetes randomized to Roux-en-Y gastric bypass (RYGB) vs intensive medical management (IMM) and matched for similar reduction in HbA1c after 1 year of treatment.

Methods

Blood samples were drawn from patients who underwent a test meal challenge before and 1 year after IMM (n?=?15) or RYGB (n?=?15).

Results

Mean HbA1c decreased from 9.7 to 6.4 % after RYGB and from 9.1 to 6.1 % in the IMM group. At 12 months, the number of diabetes medications used per subject in the RYGB group (2.5?±?0.5) was less than in the IMM group (4.6?±?0.3). After RYGB, FGF19 increased in the fasted (93?±?15 to 152?±?19 pg/ml; P?=?0.008) and postprandial states (area under the curve (AUC), 10.8?±?1.9 to 23.4?±?4.1 pg?×?h/ml?×?10³; P?=?0.006) but remained unchanged following IMM. BAs increased after RYGB (AUC ×10³, 6.63?±?1.3 to 15.16?±?2.56 μM?×?h; P?=?0.003) and decreased after IMM (AUC ×10³, 8.22?±?1.24 to 5.70?±?0.70; P?=?0.01). No changes were observed in the ratio of 12α-hydroxylated/non-12α-hyroxylated BAs. Following RYGB, FGF19 AUC correlated with BAs (r?=?0.54, P?=?0.04) and trended negatively with HbA1c (r?=??0.44; P?=?0.09); these associations were not observed after IMM.

Conclusions

BA and FGF19 levels increased after RYGB but not after IMM in subjects who achieved similar improvement in glycemic control. Further studies are necessary to determine whether these hormonal changes facilitate improved glucose homeostasis.

     

Gastric Stenosis After Laparoscopic Sleeve Gastrectomy: Diagnosis and Management

Purpose

The use of laparoscopic sleeve gastrectomy (LSG) is increasing worldwide. Although post-LSG gastric stenosis (GS) is less frequent, it has not been well defined and lacks standardized management procedures. The objective of the present study was to describe a series of patients with GS symptoms after LSG and to develop a standardized management procedure for this complication.

Methods

We performed a retrospective analysis of a prospective database of patients presenting with GS after LSG procedures performed between January 2008 and March 2014. The primary efficacy criterion was the frequency of post-LSG GS. GS was classified as functional (i.e. a gastric twist) or organic. The secondary efficacy criteria included the time interval between LSG and diagnosis of GS, the type of stenosis, the type of management, and the follow-up data.

Results

During the study period, 1210 patients underwent primary or secondary LSG. Seventeen patients had post-operative symptoms of GS (1.4 %); one patient had achalasia that had not been diagnosed preoperatively and thus was excluded from our analysis. The median time interval between LSG and diagnosis of GS was 47.2 days (1–114). Eleven patients had organic GS and six had functional GS. Seven patients required nutritional support. Endoscopic treatment was successful in 15 patients (88.2 %) after balloon dilatation (n?=?13) or insertion of a covered stent (n?=?2). Two of the 15 patients required conversion to Roux-en-Y gastric bypass (11.8 %).

Conclusion

GS after LSG is a rare complication but requires standardized management. Most cases can be treated successfully with endoscopic balloon dilatation.
