Facial trauma can cause skin wounds with uneven and discoloured edges that require healing by secondary intention. These wounds often produce excess collagen fibres, leading to fibrosis and hypertrophic scars that can cause discomfort and negatively impact the patient's quality of life. A man suffered facial trauma due to a motor vehicle accident, resulting in a fracture of the left zygomatic-maxillary complex. He underwent surgery to fix the fracture and reconstruct his eyelid but developed a hypertrophic scar during recovery that caused eye dryness and discomfort. To treat the scar, Dermatix silicone gel (SG) (Viatris, Canonsburg, PA) was applied twice a day. After two months of treatment, the scar had improved significantly, and the patient's eyelid function had also improved. This case describes the use of Dermatix SG to treat a patient with a traumatic hypertrophic scar of the eyelid associated with eyelid malposition. Silicone gel is a non-invasive treatment for scars and has been shown to be effective in reducing scar elevation and erythema. However, there is a gap in the literature regarding the routine use of SG to preserve functionality and aesthetics in traumatic hypertrophic scars of complex anatomical structures. Further studies are needed to understand the principles of using SG for these types of scars to improve functional and aesthetic outcomes. Applying Dermatix SG twice a day for 60 days corrected a patient's functional and aesthetic issues. More studies should be conducted to investigate the product's effectiveness further.

Observational Study
The spectrum of indications for primary caesarean section changes with advancing parity. As parity advances more cesarean section are done for maternal rather than fetal indications. The objective of this study was to determine the indications and complications of caesarean section in multiparous women with history of previous vaginal delivery. This cross-sectional descriptive observational study was conducted in Mymensingh Medical College Hospital from January 2019 to June 2019 among 100 purposively selected multiparous women who underwent primary caesarean section. A well-designed, semi-structured questionnaire was used to collect data by face-to-face interview, clinical examinations and laboratory investigations. Data analysis was conducted in SPSS 20.0 version. Majority (74.0%) of the women in this study were in the age group 21-30 years with mean age of 26.3±5.76 years. Majority of the patients were of second gravida (42.0%) followed by third gravida (33.0%). The highest gravida in this study was 6th. Most of the patients were of para 1(44.0%). Highest para in this study was para 5. The most common indication of caesarean section in this study was foetal distress (26.0%). The next common indications were cephalo-pelvic disproportion (22.0%), antepartum haemorrhage (13.0%), mal-presentaion or mal-position (16.0%). Other causes were PROM (8.0%), prolonged labour (6.0%), cord prolapse (2.0%), post-dated pregnancy (4.0%), severe pre-eclampsia (2.0%) and secondary subfertility (1.0%). There was no case of maternal mortality in this study but 15 mothers suffered from various post-operative complications like wound infection (4.0%), UTI (4.0%), puerperal pyrexia (3.0%), postpartum haemorrhage (3.0%) and paralytic ileus (1.0%). Among the babies delivered 97 were live births. Among the 97 live births 11(11.34%) were preterm babies. Among the babies delivered majority (85.0%) was with good APGAR score (7-10). In conclusion it can say that a multiparous women in labour requires the same attention as that of primigravida. A parous women needs good obstetric care to improve maternal and neonatal outcome and still keeping caesarean section to a lower rate.

Measurement of the Acetabular Cup Orientation after Total Hip Arthroplasty Based on Three-Dimensional Reconstruction from a Single X-ray Image Using Generative Adversarial Networks.
BACKGROUND
The purpose of this study was to reconstruct three-dimensional (3D) computed tomography (CT) images from single anteroposterior (AP) postoperative total hip arthroplasty (THA) X-ray images using a deep learning algorithm known as generative adversarial networks (GANs) and to validate the accuracy of cup angle measurement on GAN-generated CT.
METHODS
We used two GAN-based models, CycleGAN and X2CT-GAN, to generate 3D CT images from X-ray images of 386 patients who underwent primary THAs using a cementless cup. The training dataset consisted of 522 CT images and 2,282 X-ray images. The image quality was validated using the peak signal-to-noise ratio (PSNR) and the structural similarity index measure (SSIM). The cup anteversion and inclination measurements on the GAN-generated CT images were compared with the actual CT measurements. Statistical analyses of absolute measurement errors were performed using Mann-Whitney U tests and nonlinear regression analyses.
RESULTS
The study successfully achieved 3D reconstruction from single AP postoperative THA X-ray images using GANs, exhibiting excellent PSNR (37.40) and SSIM (0.74). The median absolute difference in radiographic anteversion (RA) was 3.45° and the median absolute difference in radiographic inclination (RI) was 3.25°, respectively. Absolute measurement errors tended to be larger in cases with cup malposition than in those with optimal cup orientation.
CONCLUSION
This study demonstrates the potential of GANs for 3D reconstruction from single AP postoperative THA X-ray images to evaluate cup orientation. Further investigation and refinement of this model are required to improve its performance.

INTRODUCTION
The umbilical venous catheter is a vital access device in neonatal intensive care units for preterm and critically ill infants. Correct positioning is crucial, as malpositioning can lead to severe complications. According to international guidelines, the position of the umbilical venous catheter tip must be assessed in real time; traditionally, the catheter is visualized with a thoracoabdominal X-ray, but one of the most effective and safest methods is therefore real-time ultrasound.
METHODS
This study compares real-time ultrasound and traditional X-ray methods for assessing umbilical venous catheter tip location in 461 cases. The rate of tip malposition was analyzed retrospectively. The secondary aim was to assess indwelling time of umbilical venous catheters and reasons of removal.
RESULTS
Real-time ultrasound tip location, found to be more reliable and efficient, demonstrated a significantly lower incidence of primary malpositioning compared to X-ray assessments (9.6 vs. 75.9%). The study also highlighted the association of real-time ultrasound with reduced catheter manipulation, fewer radiographs, and higher indwelling times of umbilical venous catheter. The multiple logistic regression showed a high probability of the central safe position of the umbilical venous catheter tip using real-time ultrasound tip location (odds ratio 29.5, 95% confidence interval: 17.4-49.4).
CONCLUSION
The findings support the adoption of real-time ultrasound in clinical settings to enhance umbilical venous catheter placement accuracy and minimize associated risks. A minimal training investment is needed to attain the proficiency to visualize the umbilical venous catheters, offering a substantial advantage in terms of both cost-effectiveness for the procedure and enhanced patient safety.

Despite advancement in surgical innovation, C1-C2 fixation remains challenging due to risks of screw malposition and vertebral artery (VA) injuries. Traditional image-based navigation, while useful, often demands that surgeons frequently shift their attention to external monitors, potentially causing distractions. In this article, we introduce a microscope-based augmented reality (AR) navigation system that projects both anatomical information and real-time navigation images directly onto the surgical field. In the present case report, we discuss a 37-year-old female who suffered from os odontoideum with C1-C2 subluxation. Employing AR-assisted navigation, the patient underwent the successful posterior instrumentation of C1-C2. The integrated AR system offers direct visualization, potentially minimizing surgical distractions. In our opinion, as AR technology advances, its adoption in surgical practices and education is anticipated to expand.

It has long been accepted that trauma is one of the most important and frequent predisposing factors for onychomycoses. However, the role of direct trauma in the pathogenesis of fungal nail infections has only recently been elucidated in a series of 32 cases of post-traumatic single-digit onychomycosis. The importance of repeated trauma due to foot and toe abnormalities was rarely investigated. : This is a multicenter single-author observational study over a period of 6 years performed at specialized nail clinics in three countries. All patient photographs taken by the author during this period were screened for toenail alterations, and all toe onychomycosis cases were checked for whether they contained enough information to evaluate potential foot and toe abnormalities. Particular attention was paid to the presence of , , , inward rotation of the big toe, and outward rotation of the little toe, as well as splay foot. Only cases with unequivocal proof of fungal nail infection by either histopathology, mycologic culture, or polymerase chain reaction (PCR) were accepted. Of 1653 cases, 185 were onychomycoses, proven by mycologic culture, PCR, or histopathology. Of these, 179 involved at least one big toenail, and 6 affected one or more lesser toenails. Three patients consulted us for another toenail disease, and onychomycosis was diagnosed as a second disease. Eight patients had a pronounced . Relatively few patients had a normal big toe position ( = 9). Most of the cases had a mild to marked (HV) (105) and a (HVI) (143), while was observed in 43 patients, and the combination of HV and HVI was observed 83 times. The very high percentage of foot and toe deformations was surprising. It may be hypothesized that this is not only a pathogenetically important factor but may also play an important role in the localization of the fungal infection, as no marked deviation was noted in onychomycoses that affected the lesser toes only. As the management of onychomycoses is a complex procedure involving the exact diagnosis with a determination of the pathogenic fungus, the nail growth rate, the type of onychomycosis, its duration, and predisposing factors, anomalies of the toe position may be important. Among the most commonly mentioned predisposing factors are peripheral circulatory insufficiency, venous stasis, peripheral neuropathy, immune deficiency, and iatrogenic immunosuppression, whereas foot problems are not given enough attention. Unfortunately, many of these predisposing and aggravating factors are difficult to treat or correct. Generally, when explaining the treatment of onychomycoses to patients, the importance of these orthopedic alterations is not or only insufficiently discussed. In view of the problems encountered with the treatment of toenail mycoses, this attitude should be changed in order to make the patient understand why there is such a low cure rate despite excellent minimal inhibitory drug concentrations in the laboratory.

OBJECTIVES
Catheter malposition after subclavian venous catheterization (SVC) is not uncommon and can lead to serious complications. This study hypothesized that the left access is superior to the right access in terms of catheter malposition after ultrasound-guided infraclavicular SVC due to the asymmetry of the bilateral brachiocephalic veins.
DESIGN
Parallel-armed randomized controlled trial.
SETTING
A tertiary referral hospital in Korea.
PATIENTS
Patients 20-79 years old who were scheduled to undergo SVC under general anesthesia.
INTERVENTIONS
Patients were randomly assigned to either the left (n = 224) or right (n = 225) SVC group. The primary outcome measure was the overall catheter malposition rate. The secondary outcome measures included catheter malposition rates into the ipsilateral internal jugular and contralateral brachiocephalic veins, other catheterization-related complications, and catheterization performance.
MEASUREMENTS AND MAIN RESULTS
The catheter malposition rate was lower (10 [4.5%] vs. 31 [13.8%], p = 0.001), especially in the ipsilateral internal jugular vein (9 [4.0%] vs. 24 [10.7%], p = 0.007), in the left SVC group than in the right SVC group. In the left SVC group, catheterization success rates on the first pass (88 [39.3%] vs. 65 [28.9%], p = 0.020) and first-catheterization attempt (198 [88.4%] vs. 181 [80.4%], p = 0.020) were higher whereas times for vein visualization (30 s [18-50] vs. 20 s [13-38], p < 0.001) and total catheterization (134 s [113-182] vs. 132 s [103-170], p = 0.034) were longer. There were no significant differences in other catheterization performance and catheterization-related complications between the two groups.
CONCLUSIONS
These findings strengthen the rationale for choosing the left access over the right access for ultrasound-guided infraclavicular SVC.

BACKGROUND
The gold standard for implant-based breast reconstruction uses acellular dermal matrices (ADMs). They provide improved inferolateral pole coverage, reduced capsular contracture rates, and increased primary expander fill volumes. However, ADMs are costly and have been associated with increased rates of postoperative infection, seroma, hematoma, implant malposition, and mastectomy flap necrosis (MFN). This study describes a novel autologous flap without the need of ADM, the serratus anterior external oblique rectus abdominis (SAEORA) flap, as an alternative in prosthetic-based breast reconstruction.
METHODS
A retrospective study was conducted on all patients who underwent SAEORA flap breast reconstruction by a single surgeon between January 1, 2013 and May 31, 2020 at a single institution. Patient demographics, diagnosis, treatment, tissue expander (TE) volume, implant size, complications, and results were assessed.
RESULTS
Forty-seven patients underwent 78 SAEORA flaps. Sixty-two had TEs placed, and 14 were direct-to-implant. Mean body mass index was 23.1 kg per m². Median primary TE fill volume was 150 mL, and final implant volume average was 450 mL. Mean follow-up was 14.5 months. Complications included infection/cellulitis (7.9%), seroma (6.6%), hematoma (5.2%), and MFN (7.9%).
CONCLUSIONS
The SAEORA flap is a novel autologous flap and is a viable option for prosthetic-based breast reconstruction, with an acceptable complication profile relative to ADM-based reconstructions. Additionally, SAEORA is MFN-resistant and has been used effectively in salvage of exposed implants or ADM, and in double-bubble deformity correction.

INTRODUCTION
Knee stiffness post-total knee arthroplasty (TKA) represents a common and challenging complication. Standard treatment protocols primarily include physical therapy, manipulation under anesthesia (MUA), fibrotic tissue release, lysis of adhesions (LOA), and in refractory cases, revision arthroplasty. However, these interventions often show minimal improvement in refractory cases. This report introduces V-Y quadricepsplasty as an innovative approach for addressing knee stiffness post-TKA, particularly in cases unresponsive to MUA and LOA, without any evidence of prosthetic component malposition or failure.
CASE REPORT
We present a case involving a middle-aged woman experiencing persistent knee stiffness post-TKA, unresponsive to both MUA and LOA. Diagnostic evaluations confirmed no malposition or failure of the prosthetic component. The patient underwent a successful V-Y quadricepsplasty, which resulted in significant improvement in her condition.
CONCLUSION
This case underscores the efficacy of V-Y quadricepsplasty in managing knee stiffness post-TKA, especially in cases where traditional treatments such as MUA and LOA are ineffective and there is no evidence of prosthetic component failure or malposition. This approach potentially offers a new avenue for treatment in similar clinical scenarios.

Review
Labour care must balance aspirations of parents with vigilance for unanticipated calamities. The 'on-site midwife-led primary care birth unit' facilitates this. The World Health Organization have replaced the traditional partograph with the 'Labour Care Guide'. An implementation project in Botswana included the mnemonic COPE: Companion, Oral fluids, Pain relief and Eliminate the supine position. The Parto-Ma project in Tanzania used guidelines, training and support to improve childbirth outcomes. We list labour practices supported by recent evidence, and highlight new developments. Foetal macrosomia increases risk but mistaken diagnosis increases caesarean births. Obstructed labour is a complex clinical diagnosis, and is difficult to predict. For shoulder dystocia prioritise delivery of the posterior shoulder, facilitated if needed by posterior axilla sling traction. 'Extended balloon labour induction' with two or three Foley catheters side by side, may reduce risks associated with uterine stimulants. Bedside ultrasound may facilitate the diagnosis of cephalic malpositions and malpresentations.
