BACKGROUND: Noncultured epidermal cell suspension (NCECS) is a commonly used surgical treatment for resistant stable acral vitiligo and vitiligo overlying joints. Platelet-rich plasma (PRP) has been reported to enhance the repigmentation response of different therapeutic modalities for vitiligo, including vitiligo surgery.

OBJECTIVE: To assess the value of adding of PRP to NCECS in the surgical treatment of acral vitiligo and vitiligo overlying joints.

PATIENTS AND METHODS: This self-controlled randomised trial included 15 patients with 30 lesions in which NCECS suspended in PRP was performed for one lesion and NCECS in ringer's lactate for another comparable lesion. Following NCECS, patients underwent thrice weekly excimer light sessions for 3 months. After 8 weeks, patients underwent preliminary assessment. By the end of the 3 months, both lesions were compared as regards improvement in surface area and pigmentation. Additionally, physician global assessment was made by a blinded investigator.

RESULTS: Significant improvement was reported in both lesional extent and pigmentation (after PRP and lactated ringer NCECS) with no statistical difference between them.

CONCLUSION: Despite previous promising results, suspending NCECS in PRP offered no privilege in surgical treatment of acral vitiligo and vitiligo overlying joints, which are quite resistant to treat.

PURPOSE: Pediatric patients in low-income countries are at a high risk of malnutrition. Numerous screening tools have been developed to detect the risk of malnutrition, including the Subjective Global Nutritional Assessment (SGNA), Pediatric Yorkhill Malnutrition Score (PYMS), Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP), and Screening Tool for Risk of Nutritional Status and Growth (STRONGkids). However, anthropometry remains the main tool for assessing malnutrition. We aimed to identify the value of four nutritional screening tools versus anthropometry for evaluating the nutritional status of children.

METHODS: We conducted a cross-sectional study of 1,000 children aged 1-12 years who visited the outpatient clinic of Cairo University Pediatric Hospital. Each participant was evaluated using anthropometric measurements (weight, length/height, and weight for length/height) as well as the PYMS, STAMP, STRONGkids, and SGNA screening tools. The sensitivities and specificities of these four tools were assessed using anthropometry as the gold standard.

RESULTS: Of the patients, 1.7% were underweight, 10.2% were wasted, and 35% were stunted. STRONGkids demonstrated the highest sensitivity (79.4%) and a high specificity (80.2%) for detecting malnutrition compared with weight for height, followed by STAMP, which demonstrated lower sensitivity (73.5%) but higher specificity (81.4%). PYMS demonstrated the lowest sensitivity (66.7%) and the highest specificity (93.5%), whereas SAGA demonstrated higher sensitivity (77.5%) and lower specificity (85.4%) than PYMS.

CONCLUSION: The use of nutritional screening tools to evaluate the nutritional status of children is valuable and recommended as a simple and rapid method for identifying the risk of malnutrition in pediatric patients.

Vertebral artery aneurysm is a rare condition with diverse clinical manifestations in pediatric patients. We present the case of a 12-year-old male who presented with diplopia, vomiting, ataxia, and severe headache. Diagnostic evaluation revealed an extracranial vertebral artery dissection with an associated aneurysm at the C3-C4 level. Despite the absence of recurrent ischemic strokes, the aneurysm posed challenges in differentiating the symptoms from other inflammatory demyelinating disorders, particularly internuclear ophthalmoplegia. Diagnosis relied on a thorough history, physical examination, and imaging studies. Magnetic resonance imaging with magnetic resonance angiography confirmed the diagnosis and played a crucial role in assessing the size, location, and extent of the aneurysm. Additionally, the imaging findings helped guide treatment decisions and determine the need for anticoagulation therapy. Regular follow-up imaging was initiated to monitor for late complications and evaluate the effectiveness of the management approach. This case highlights the atypical presentation of vertebral artery aneurysm in a pediatric patient, underscoring the importance of clinical suspicion and the role of advanced imaging techniques in facilitating accurate diagnosis and guiding appropriate management. Prompt diagnosis and optimal utilization of imaging modalities are essential in preventing severe morbidity and mortality. Further research is warranted to enhance our understanding of this condition and refine imaging and management protocols in pediatric population.

BACKGROUND: Proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) can be catastrophic complications associated with adult spinal deformity (ASD) surgery. These complications are markedly influenced by osteoporosis, leading to additional vertebral fracture and pedicle screw loosening. The MRI-based vertebral bone quality score (VBQ) is a newly developed tool that can be used to assess bone quality.

OBJECTIVE: To investigate the utility of the VBQ score in predicting PJK and/or PJF (PJF/PJK) after ASD correction.

METHODS: We conducted a retrospective chart review to identify patients age ≥50 years who had received ASD surgery of 5 or more thoracolumbar levels. Demographic, spinopelvic parameters, and procedure-related variables were collected. Each patient's VBQ score was calculated using preoperative T1-weighted MRI. Univariate analysis and multivariate logistic regression were performed to determine potential risk factors of PJK/PJF. Receiver operating characteristic analysis and area-under-the-curve values were generated for prediction of PJK/PJF.

RESULTS: A total of 116 patients were included (mean age, 64.1 ± 6.8 years). Among them, 34 patients (29.3%) developed PJK/PJF. Mean VBQ scores were 3.13 ± 0.46 for patients with PJK/PJF and 2.46 ± 0.49 for patients without, which was significantly different between the 2 groups ( P < .001). On multivariate analysis, VBQ score was the only significant predictor of PJK/PJF (odds ratio = 1.745, 95% CI = 1.558-1.953, P < .001), with a predictive accuracy of 94.3%.

CONCLUSION: In patients undergoing ASD correction, higher VBQ was independently associated with PJK/PJF occurrence. Measurement of VBQ score on preoperative MRI may be a useful adjunct to ASD surgery planning.
