Aim: To utilize three-dimensional (3D) geometric morphometry for visualization of the level of facial asymmetry in patients with the oculo-auriculo-vertebral spectrum (OAVS).
Materials And Methods: Three-dimensional facial scans of 25 Czech patients with OAVS were processed. The patients were divided into subgroups according to Pruzansky classification.
Simultaneous breast augmentation with mastopexy is growing in popularity. It is a complex procedure that can lead to post-operative complications, patient dissatisfaction, and increased risk of litigation. The aim of this study is to describe an approach for the inverted-T augmentation-mastopexy technique, which limits intraoperative modifications, minimizes errors, and decreases post-operative complications and patient dissatisfaction.

The objective of this study was to compare the palatal morphology in children treated with different surgical protocols. Palatal shape was assessed with geometric morphometrics (GM) including Procrustes superimposition, principal component analysis (PCA), and permutation tests with 10,000 permutations, in 24 children treated with two-stage repair with a late palatoplasty (Prague group; mean age at assessment 8.

- The study examines primary plasma cell leukemia (PCL), previously defined by ≥ 20% circulating plasma cells, now suggested to be diagnosed by a lower threshold of ≥ 2% CTCs, indicating it might just be ultra-high-risk multiple myeloma (MM).
- Researchers measured CTC levels in 395 newly diagnosed transplant-ineligible MM patients and found that those with 2%-20% CTCs had poorer survival outcomes compared to those with < 2%, emphasizing the clinical relevance of a lower cutoff.
- The findings support using the 2% cutoff as a potential biomarker for identifying hidden primary PCL and advocate for flow cytometry assessment during MM diagnosis to improve patient stratification and treatment decisions.
Plasma cell leukaemia (PCL) is a rare and very aggressive plasma cell disorder. Preventing a dismal outcome of PCL requires early diagnosis with appropriate analytical tools. Therefore, the investigation of 33 patients with primary and secondary PCL was done when the quantity of circulating plasma cells (PCs) using flow cytometry (FC) and morphology assessment was evaluated.

Despite, facial appearance in subjects with CLP is rarely ideal and residual stigmata are easy to notice in many patients irrespective of the protocol. The prospective controlled investigations are optimal for comparing effectiveness of treatment protocols.

Materials And Methods: Patients treated in Warsaw, Poland (n = 32), Prague, Czech Republic (n = 33) and Bratislava, Slovakia (n = 30) were included in this retrospective study. Each cleft center used a unique surgical protocol.
Results of a comparison of the outcomes of treatment of cleft lip and palate can be affected by growth characteristics of populations from which subjects with the clefts are derived. Moreover, conventional cephalometric techniques used in cleft studies for analysis of facial morphology provide only a partial description of shape and are confounded by biases regarding the reference structures. In this retrospective comparison, craniofacial morphology of preadolescent patients with unilateral cleft lip and palate treated in Warsaw (n = 35, age = 10.
