Despite advances in neonatal care, neonatal jaundice remains a common problem in maternity wards. The present retrospective epidemiological study collected data on a sample of 710 newborns and compared the incidence of neonatal jaundice in infants born to Rh (D) negative and 0 Rh (D) positive mothers. The primary aim was to determine whether the higher incidence of maternal alloimmunisation in newborns was causally related to a potentially higher incidence of neonatal jaundice in newborns of 0 Rh (D) positive mothers. To the end, we investigated a possible association between the incidence of neonatal jaundice in 0 Rh (D) positive mothers and the neonatal blood group. The incidence of neonatal jaundice was not found to differ between maternal blood groups. We discuss new preventive measures that may reduce the incidence of neonatal jaundice and thereby reduce the length of hospital stay.

The study aimed to establish the impact of age on the predictive capability of ferritin, ferritin-hemoglobin ratio (FHR), IL-6, and sIL-2R in COVID-19 patients. Compared to patients with moderate condition, patients with severe condition had higher ferritin level (441.0 [188.0-829.8] ng/mL vs 281.0 [172.0-388.0] ng/mL, p = 0.002), sIL-2R level (6.0 [4.7-9.0] pg/mL vs 5.3 [3.7-6.9] pg/mL, p = 0.020), FHR (38.4 [15.1-63.4] vs 22.0 [12.1-32.1], p = 0.002). The area under the curves (AUC) for discriminative capabilities of the following biomarkers for severe condition were assessed in patients aged <65 years and patients aged ≥65 years: ferritin (AUC = 0.585, p = 0.309 vs AUC = 0.683, p = 0.002), FHR (AUC = 0.589, p = 0.302 vs AUC = 0.688, p = 0.002), IL-6 (AUC = 0.503, p = 0.972 vs AUC = 0.647, p = 0.019), and sIL-2R (AUC = 0.549, p = 0.552 vs AUC = 0.646, p = 0.017). Also AUCs for discriminative capabilities for in-hospital mortality were compared in patients aged <65 years and ≥65 years: ferritin (AUC = 0.607, p = 0.628 vs AUC = 0.661, p = 0.105), FHR (AUC = 0.612, p = 0.621 vs AUC = 0.688, p = 0.002), IL-6 (AUC = 0.580, p = 0.724 vs AUC = 0.695, p = 0.016), and sIL-2R (AUC = 0.620, p = 0.491 vs AUC = 0.695, p = 0.029). Thus, ferritin, FHR, IL-6, and sIL-2R didn't show acceptable predictive value for severe condition and lethal outcome in patients aged <65 years but had high predictive value for lethal outcome in patients aged ≥65 years.

Edema of the psoas major muscle can indicate various pathologies, such as infection, malignancy, and trauma, but it can also result from benign causes like delayed-onset muscle soreness (DOMS). This article presents the case of a 44-year-old female patient who developed DOMS in the psoas major after participating in an intense abdominal workout. The patient reported hip pain that began a day after the workout, which was confirmed by magnetic resonance imaging (MRI) revealing significant edema in the psoas major muscles, particularly on the right side. Conservative treatment with rest and analgesics led to full recovery within two weeks. DOMS, typically associated with eccentric exercises, can be mistaken for more serious conditions, but its recognition is crucial to avoid unnecessary investigations and interventions. This case highlights the importance of clinical history and imaging findings in distinguishing DOMS from other causes of muscle edema, emphasizing the need for accurate diagnosis to ensure appropriate management.

Background: The cranial nerve (CN) V and adjacent neurovascular structures are crucial landmarks in microvascular decompression (MVD). MVD of CN V is the most effective treatment for patients with drug-resistant trigeminal neuralgia (TN) diagnosis. The endoscope-assisted retrosigmoid approach (RSA) provides better exposure and less cerebellar retraction in the corridor towards the cerebellopontine angle (CPA).

Methods: Five adult cadaver heads (10 sides) underwent dissection of the MVD in park bench position. MVD was simulated using microsurgical RSA, and the anatomical landmarks were defined. Microsurgical dissections were additionally performed along the endoscopic surgical path. Additionally, we present an illustrative case with TN caused by anterior inferior cerebellar artery (AICA) compression. The CN V and its close relationships were demonstrated. Endoscopic and microscopic three-dimensional pictures were obtained.

Results: This study increases the anatomical and surgical orientation for CN V and surrounding structures. The CN V arises from the lateral part of the pons and runs obliquely upward toward the petrous apex. It has motor roots that leave from pons antero-supero-medial direction to the sensory root. The endoscopic instruments provide perfect visualization with minimal cerebellar retraction during MVD.

Conclusion: MVD surgically targets the offending vessel(s) leading to TN and aims to create a disconnected area. The combination of preoperative radiographic assessment with and anatomical correlation provides safe and effective application while facilitating selection of the most appropriate approach. The RSA allows satisfactory visualization for CN V. Endoscope-assisted microsurgery through the CPA is a challenge, it should be performed with advanced anatomical knowledge.

Ovarian carcinosarcoma, also referred as malignant mixed Mullerian tumour, is an uncommon, highly aggressive and malignant neoplasm which makes up 1 to 4% of all ovarian tumours. It is biphasic involving both malignant sarcomatous (mesenchymal) and carcinomatous (epithelial) cells. There are various subtypes such as serous and endometrioid. However, the mesenchymal part is sarcomatous. About 90% of cases of ovarian carcinosarcoma spread outside the ovary. The two most accepted theories of origin for carcinosarcoma of the ovary are the collision and conversion theories. A third theory is the combination theory. Prognosis remains poor even when still localised in the ovary. In the last few years, there has been no change in the survival rate. The median survival rate is lower than 2 years. Clinical features mainly include lower abdominal pain and a palpable abdominal mass. Ovarian carcinosarcoma remains poorly understood and understudied. Being a rare tumour, elaborate therapeutic consensus is not available for ovarian carcinosarcoma. The main treatment involves cytoreductive surgery and then chemotherapy. The type of chemotherapy, role of radiotherapy and novel therapies need to be further studied. The main objective of this article is to review the current literature on carcinosarcoma of the ovary.

Recent advancements in digital technologies have transformed clinical workflows in dentistry, ensuring precise restorations. Custom-made crowns and fixed partial dentures (FPDs) now rely on virtual articulation. The digital facebow provides individualized data for CAD settings, streamlining the fabrication via digital workflow. For the purpose of demonstrating the differences observed during fabrication, we present a case report involving a 68-year-old patient seeking a replacement for missing teeth 24, 25, 26, and 27. The treatment plan involved the fabrication of an implant-supported FPD using monolithic zirconia (ZrO2). However, technical hurdles emerged during the planning phase, primarily due to spatial limitations posing a risk of mechanical failure over time. Consequently, we pivoted approach towards a porcelain fused to metal (PFM) FPD. For the PFM FPD, individual values from the digital facebow adjusted both virtual and conventional articulators. For comparison, two ZrO2 FPDs were milled-individual settings and average settings. All restorations underwent assessment for occlusion in maximal intercuspal position and eccentric mandible movements. In conclusion, the case report showed that individualized PFM FPD required minimal adjustments compared to milled ZrO2 restorations, whether using individual or average values. Utilizing individual values from the digital facebow reduced operator working time and minimized the intraoral adjustments.

Chronic diarrhea is a significant challenge in clinical practice because of its high prevalence and various causes. Comprehensive clinical assessment and stepwise laboratory approach are crucial for an accurate diagnosis. This report presents a case of an adult woman who experienced chronic watery diarrhea, complicated by renal impairment and multiple electrolyte imbalances, including hypokalemia, hypophosphatemia, and metabolic acidosis. The diagnosis of a vasoactive intestinal polypeptide-secreting tumor (VIPoma) with liver metastases was confirmed by elevated serum levels of a vasoactive intestinal polypeptide (VIP) and imaging findings of a pancreatic mass with multiple hepatic lesions. Preoperative management, including fluid rehydration, electrolyte correction, and somatostatin analog therapy, significantly improved her clinical symptoms. Subsequent surgical tumor removal and radiofrequency ablation of the hepatic lesions resulted in complete resolution of symptoms and normalized VIP levels. This case emphasizes the importance of early recognition of this rare tumor in patients with chronic diarrhea to improve clinical outcomes.

The advent and dominance of social media in our daily lives is not a matter of discussion, and very few minimalistic individuals have tried to decrease this technological dependency, which can become toxic and noxious for the development of an autonomous personality and free thinking. Academic faculties claim a depauperation in terms of their freedom but are also not free from duties, responsibilities, and obligations. Here, duties, responsibilities, obligations, and freedom are addressed in historical terms as the university as an institution developed over the centuries after its founding in the 11th century is currently under attack. We premonish that these concepts must still be reiterated and divulgated to students and fellows in academia. Galilei's "Eppur si muove" ("and yet it moves") are the words pronounced by the Italian mathematician, physicist, and philosopher Galileo Galilei that should resonate in censorship bodies now and in the future.

X-linked agammaglobulinemia (XLA) was one of the first inborn errors of immunity to be described. It is caused by pathogenic variants in the gene for Bruton tyrosine kinase (BTK), which has important functions in B cell development and maturation. Recurrent bacterial infections in the first two years of life and hypogammaglobulinemia with absent B cells in male patients are the most common symptoms. A four-month-old male patient underwent surgical removal of urachus persistens complicated with recurrent scar abscesses. Hypogammaglobulinemia (IgG, IgA, and IgM), low phagocytic activity, mild neutropenia, and a normal percentage of B cells were observed in the patient's immune laboratory profile. Over time, he suffered recurrent respiratory infections (otitis media and rhinosinusitis) and developed B cell depletion, but interestingly, this was with a normalisation of IgG and IgA levels along with undetectable IgM. Molecular-genetic testing confirmed the presence of the pathogenic variant c.1843C>T in the BTK gene, which is associated with a milder phenotype of XLA. Molecular-genetic testing uncovers the variability of clinical and laboratory features of apparently well-known inherited disorders. Patients with mild "leaky" XLA may have normal levels of non-functional or oligoclonal immunoglobulins.

Zirconia ceramics have become popular among other dental ceramics thanks to their biological, mechanical, optical, and aesthetic properties. CAD/CAM (computer-aided design/ computer-aided manufacturing) technology improvement has played a vital role in the increased popularity of zirconia ceramics; easy computer manipulation significantly expanded the possibility of using different types of restorations. Zirconia ceramics have a broad spectrum of indications in prosthetic dentistry, from simple restorations to complex structures supported by dental implants. A good orientation in the classification, features, and manipulation of zirconia ceramics is the main key to success.
