Atypical trigeminal neuralgia (ATN) is a chronic pain condition characterized by persistent facial pain that does not respond well to conventional medical treatments, often leading to significant impairment in quality of life. This study examined the clinical characteristics and surgical outcomes of microvascular decompression combined with nerve combing in patients with ATN.

We conducted a retrospective analysis of surgical techniques, clinical data, and treatment outcomes in 40 patients from January 2009 to January 2018. Pain levels and patient prognoses were assessed using the Visual Analog Scale and the Barrow Neurological Institute (BNI) pain score. Dynamic monitoring of arterial blood pressure was performed, and levels of total adrenaline, norepinephrine, and dopamine were measured before and during the nerve combing procedure.

During surgery, veins combined with arachnoid adhesions and arachnoid adhesions alone were observed compressing the trigeminal nerve in seven patients (17.50%) and 33 patients (82.50%), respectively. Immediate postoperative BNI scores indicated excellent outcomes (P = 2) in 30 patients (75.00%) and good outcomes (P = 3) in four patients (10.00%). Long-term postoperative BNI scores showed excellent outcomes (P = 2) in 25 patients (62.50%) and good outcomes (P = 3) in seven patients (17.50%). All patients experienced an increase in arterial blood pressure during nerve combing, and the mean levels of adrenaline and norepinephrine before combing showed significant improvement (P < 0.05).

Microvascular decompression combined with nerve combing achieves favorable results in treating ATN. Long-term trigeminal nerve compression and central sensitization may contribute to the etiology in these patients.

Like other drugs, adjuvants are ligands with distinct structures that interact with specific cell receptors, modulating the immune response. This definition excludes formulations and delivery systems. New adjuvants may be discovered using methods based on a ligand and its receptor’s structural and functional traits, a process known as rational drug design. This strategy requires detailed information about both the receptors and their ligands. Such information is obtained using techniques like X-ray crystallography and 2D-nuclear magnetic resonance (NMR) to establish the spatial interactions between a ligand’s functional groups and its receptor. This data is necessary to establish reliable structure-activity relationships, which, when applied to computer-aided drug design, facilitate the creation of better adjuvants as an empirical strategy. Since Quillaja saponin adjuvants likely act separately on innate and adaptive immune cells via specific functional groups and unidentified cell receptors, it is crucial to identify these receptors. This task may be achieved using bioorthogonal chemistry and proteomic methods to identify and isolate the receptors. Initially focusing on those unidentified receptors where chemical modifications of these glycosides, such as the aldehyde group and fucose residue, cause drastic changes in adjuvanticity. The isolated receptor(s) can then be characterized by X-ray crystallography and/or 2D-NMR; this information can be applied to computer-aided drug design to rationally design new derivatives. This methodology will prevent the proposition of dubious structure-activity relationships based on incomplete immunological data, unknown receptors, and unsuspected physical factors, providing essential information for designing new adjuvants and elucidating these compounds’ mechanisms of action.

Portal vein thrombosis (PVT) is a challenging complication in liver cirrhosis, with no currently available sensitive diagnostic markers. This study aimed to investigate the potential of neutrophil extracellular traps (NETs) and Deoxyribonuclease (DNase) as diagnostic indicators for PVT in chronic hepatitis B (CHB)-related decompensated cirrhosis.

We analyzed 145 CHB-related decompensated cirrhosis patients from the Ditan study and 33 from the Changgung validation study, categorizing them based on PVT occurrence. Plasma samples were assessed for NET markers, including cell-free DNA (cfDNA) and histone-DNA complexes, along with DNase activity.

PVT patients exhibited elevated levels of cfDNA and histone-DNA complexes, and reduced DNase activity. This pattern persisted regardless of hepatocellular carcinoma (HCC) status. Histone-DNA levels, DNase activity, and hemoglobin were identified as independent risk factors for PVT. Receiver operating characteristic curve analysis revealed that high histone-DNA levels may serve as a potential diagnostic marker for PVT, with an area under the curve of 0.8628 in the Ditan study and 0.7521 in the Changgung study. When combined with cfDNA and DNase activity, the area under the curve improved to 0.8774 in the Ditan study and 0.7975 in the Changgung study.

Imbalances in NET homeostasis are associated with PVT in CHB-related decompensated cirrhosis, including cases involving HCC. Histone-DNA complexes, a significant risk factor for PVT, show potential as a diagnostic marker for PVT in decompensated cirrhosis, particularly in HBV-related HCC.

Castleman disease (CD) is a lymphoproliferative condition with a broad range of morphological and clinical presentations. It is categorized into distinct pathological and clinical subtypes, including localized unicentric CD, idiopathic multicentric CD, and human herpesvirus 8-associated or human herpesvirus 8-negative variants. Diagnosing CD requires adherence to internationally recognized guidelines that integrate clinical, laboratory, and histological findings. However, distinguishing CD from other diseases can be complex, as numerous benign and malignant conditions can mimic its features. Additionally, individuals diagnosed with CD are at an elevated risk of developing various malignancies. In this article, we reviewed benign and malignant conditions that can mimic CD.

Literature search is conducted and reviewed.

Mimickers of CD include follicular hyperplasia, indolent B-cell lymphoproliferative disorders, peripheral T-cell malignancies, classic Hodgkin lymphoma, follicular dendritic cell tumors, plasma cell disorders, immunoglobulin G4 -related lymphadenopathy, autoimmune-associated lymphadenopathy, infectious causes of lymphadenopathy, and systemic syndromes like POEMS and TAFRO. Various malignancies are associated with CD, including plasma cell proliferations, lymphomas, follicular dendritic cell neoplasms, and Kaposi sarcoma.

This review explores the differential diagnoses and neoplasms linked to CD, emphasizing their role in accurate classification, treatment decisions, and patient management. A comprehensive understanding of CD and its mimickers is crucial for ensuring accurate diagnosis and appropriate patient management in clinical practice.

Disorders of blood lipids and lipoproteins are a global problem and a high-risk factor for atherosclerosis in patients with rheumatoid arthritis (RA). This article presents data on the influence of inflammation on proatherogenic disorders of lipid and lipoprotein metabolism, with an emphasis on proinflammatory cytokines. It analyzes the blood lipid profile in RA patients and identifies the need to study subfractions of high-density lipoproteins and their function in reverse cholesterol transport in RA patients as a more promising direction for clarifying cardiovascular risk. Depending on their type and metabolites, lipids may either promote disease progression or protect against RA. Supported by the close connection between altered lipid metabolism and chronic autoimmune inflammation, specific lipid profiles are emerging as unique disease biomarkers with diagnostic, predictive, and prognostic potential. Studying the influence of the immunoinflammatory process on lipids and lipoproteins in the blood of patients with RA will not only deepen knowledge about the pathogenesis of chronic inflammation but also expand understanding of the pathogenetic and prognostic significance of lipids, allowing for early diagnosis of dyslipidemia in RA at a qualitatively new level.

The role of radiosurgery in the treatment of grade 2 meningioma remains unclear. This study aimed to evaluate the long-term outcomes of gamma knife radiosurgery (GKRS) in patients with grade 2 meningiomas and to identify factors influencing tumor control and survival.

In this retrospective study, seventy patients underwent GKRS for grade 2 meningioma between 2007 and 2016. Tumor recurrence was categorized as local, marginal, or distant. Survival curves were estimated using the Kaplan-Meier method, while the log-rank test and Cox proportional hazards model were employed to analyze potential risk factors.

The median follow-up period was 48 months (range: 8 to 132 months). The one-year, three-year, and five-year local control rates were 92%, 73%, and 65%, respectively. The one-, three-, and three-year progression-free survival rates were 87%, 51%, and 44%, respectively. Multiple lesions and multiple prior recurrences were identified as negative predictors of marginal control and progression-free survival. Similarly, multiple lesions and marginal doses ≤13 Gy were associated with poor local control. Serious complications related to gamma knife use occurred in 4% of patients.

Our results support that GKRS is a reasonable treatment option in the management of grade 2 meningiomas. However, outfield progression remains a significant challenge, particularly in patients with multiple prior relapses and/or multiple lesions. More aggressive treatment strategies should be explored for these high-risk patients.

Pancreatic cancer encompasses a heterogeneous group of malignancies, primarily divided into endocrine and exocrine types, with pancreatic ductal adenocarcinoma representing approximately 90% of cases. While the incidence of pancreatic cancer is relatively low, accounting for about 3% of all cancers in the United States, it has a disproportionately high mortality rate, responsible for around 7% of cancer-related deaths. In 2024, it is estimated that there will be 66,440 new diagnoses and 51,750 fatalities associated with this disease. The overall five-year survival rate remains alarmingly low at just 13%, primarily due to late-stage diagnosis; over 80% of pancreatic ductal adenocarcinoma patients present with unresectable tumors and metastases at the time of diagnosis. This review aims to highlight recent advancements in imaging and laboratory tests that are paving the way for innovative screening and diagnostic approaches. Some of the modalities discussed in detail include endoscopic ultrasound (EUS) and its modifications, such as EUS elastography, EUS contrast-enhanced, and EUS Fine Needle Aspiration, as well as multi-detector computed tomography scans, magnetic resonance imaging, and positron emission tomography scans. Furthermore, laboratory tests, such as multi-marker analysis and circulating tumor DNA, alongside traditional markers like carcinoembryonic antigen, carbohydrate antigen 19-9, and carbohydrate antigen 125, are explored. The role of radiomics and proteomics in the early detection of pancreatic cancer is also discussed. These developments hold the promise of improving early detection, which is crucial for enhancing patient outcomes in pancreatic cancer. On the treatment front, conventional therapies, including platinum-based therapies and monoclonal antibodies, are reviewed, alongside innovative therapies such as immunotherapies, chimeric antigen receptor T-cell therapy, and cancer vaccines. It has been increasingly recognized that the intricate patho-mechanisms underlying tumorigenesis in pancreatic cancers necessitate a deeper understanding to facilitate targeted therapeutic strategies. We also explore various newer therapies currently in clinical trials, assessing their practicality and effectiveness in real-world settings.

Few cases of tenofovir resistance have been reported, and the appropriate treatment for such cases remains unclear. We aimed to share a case of a chronic hepatitis B mono-infected patient with potential tenofovir resistance who required combined lamivudine and tenofovir therapy to achieve adequate viral suppression. The patient’s viral load (plasma) was monitored using the cobas® hepatitis B virus Test on the cobas® 6800 system. Hepatitis B antiviral drug resistance (AVDR) mutations were assessed by amplicon-based sequencing. Plasma was extracted using the MagNa Pure 24 system, and polymerase chain reaction targeting the polymerase gene (860bp) was performed. Sequencing was conducted on GridION R10.4.1 flow cells, and the resulting FASTQ files were analyzed using DeepChek®-HBV Software. We describe a female patient in her 60s with chronic hepatitis B who was e-antigen positive. She met treatment criteria in May 2020, when her alanine transaminase levels were 1.5 times above the upper limit of normal. She was initially started on entecavir but had to switch to tenofovir alafenamide in June 2020 due to a rash. Despite three years of tenofovir therapy, her viral load remained unsuppressed. AVDR testing identified two suspected tenofovir resistance mutations (V191I and A317S). Since no mutations associated with lamivudine resistance were detected, the patient was treated with a combination of lamivudine and tenofovir, achieving viral suppression after four months. Although rare, tenofovir resistance should be considered in patients with persistent viremia despite long-term therapy. AVDR sequencing facilitated the detection of potential tenofovir resistance and guided treatment decisions, leading to successful viral suppression in this case.

Breast cancer remains one of the leading causes of cancer-related deaths worldwide. Early detection of breast cancer significantly improves outcomes and survival rates, minimizing treatments. Imaging techniques are critical in identifying abnormalities and diagnosing breast cancer at its earliest stages, often before clinical symptoms emerge. Mammography remains standard for screening in average-risk women, while supplementary methods like ultrasound, magnetic resonance imaging, and tomosynthesis enhance detection rates, particularly in women with dense breasts or those at high risk. Given that certain factors, such as family history, age, genetic mutations, and breast density, affect the risk of developing breast cancer, some women may benefit from earlier or more frequent screenings. Personalized screening protocols are becoming more common, tailoring the type and frequency of imaging to the individual’s risk profile. Newer technologies, such as molecular breast imaging and contrast-enhanced mammography show promise but require further validation for widespread use. In conclusion, imaging techniques including mammography, ultrasound, magnetic resonance imaging, and newer technologies like three-dimensional mammography and molecular breast imaging are essential tools in the early detection of breast cancer, leading to better outcomes for patients. This literature review provides an overview of current breast cancer imaging methods, their role in early diagnosis, and their effectiveness and limitations.

Oral contraceptive pills (OCPs) are commonly used for contraception, but their long-term effects on oxidative stress, lipid profiles, and liver function remain unclear. This study aimed to evaluate the impact of intermediate-term OCP use (Yasmin) on oxidative stress, lipid profile, and liver function, with particular emphasis on antioxidant markers, lipid metabolism, and hepatic enzyme activity, to better understand the potential metabolic and hepatic effects.

A case-control study was conducted in Maysan Governorate, Iraq, involving 150 women (100 OCP users and 50 non-users). Blood samples were collected from Al-Sadr Teaching Hospital and a specialized clinic between February and April 2023. Serum levels of antioxidants, lipids, and liver enzymes were measured using biochemical assays.

OCP users had significantly lower levels of glutathione peroxidase vitamin E and uric acid (p < 0.001) compared to non-users. Lipid profiles showed that OCP users had higher levels of triglyceride and low-density lipoprotein (p < 0.05), whereas total cholesterol was significantly higher in non-users (p < 0.05). Liver enzyme activity, including alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and total serum bilirubin, did not show statistically significant differences (p > 0.05). Longer duration of OCP use was significantly negatively correlated with vitamin E levels (r = −0.67), glutathione peroxidase activity (r = −0.56), uric acid levels (r = −0.45) and high-density lipoprotein (r = −0.54). Positive correlations were found between the duration of OCP use and total cholesterol (r = 0.62), triglyceride (r = 0.58), low-density lipoprotein (r = 0.60), and liver enzymes alanine aminotransferase (r = 0.66) and aspartate aminotransferase (r = 0.64).

Intermediate-term OCP use was associated with changes in oxidative stress and lipid metabolism, potentially increasing cardiovascular and metabolic risks. Regular monitoring of these parameters is recommended for OCP users.
