Photodynamic therapy in the treatment of the right buccal mucosa verrucous carcinoma: a case report and literature review / 口腔疾病防治

Objective@#To explore the photodynamic treatment method and therapeutic effect of oral verrucous carcinoma and to provide a reference for the clinic.@*Methods@#This study follows the requirements of medical ethics. This paper summarized the photodynamic treatment of an oral verrucous carcinoma with a diameter of approximately 2.5 cm in the right buccal mucosa and retrospectively analyzed the characteristics and treatment of oral verrucous carcinoma and the photodynamic treatment of potential malignant lesions of the oral mucosa through a review of the literature.@*Results@#After four rounds of photodynamic therapy, the size of the right buccal lesion was significantly reduced. After 6 months of follow-up, the white verrucous hyperplasia of the right buccal mucosa had completely subsided, and there was no obvious scar formation. Three years after treatment, there was no recurrence of the lesion in the right buccal mucosa and no obvious scar formation in the treated area. The degree of mouth opening was 3 fingers, and there was no lymph node enlargement in the bilateral submandibular, submental or neck. The literature review shows that oral verrucous carcinoma is a rare subtype of squamous cell carcinoma with the characteristics and biological behaviors of slow growth, low malignancy, and rare metastasis. Surgery is the preferred treatment, but there are some limitations. Photodynamic therapy is a minimally invasive, repeatable treatment with mild adverse reactions. In recent years, photodynamic therapy has been gradually applied for the treatment of potential malignant disorders of the oral mucosa and early oral squamous cell carcinoma and has achieved positive results, but it has not been reported for the treatment of oral verrucous cancer@*Conclusion@#Photodynamic therapy is a new option for nonsurgical resection of oral verrucous carcinoma.

Exploring the mechanism of Xihuang Pill's anti-hyperplasia of mammary glands effect based on UPLC-Q-orbitrap-MS technology / 药学学报

Based on UPLC-Q-orbitrap-MS and biological network analysis tools, the mechanism of Xihuang Pill in improving hyperplasia of mammary glands was systematically analyzed. The rat model of hyperplasia of mammary glands was established by intramuscular injection of estradiol benzoate and progesterone. LC-MS tissue metabolomics was used to explore the key metabolites and metabolic pathways of Xihuang Pill in improving hyperplasia of mammary glands in rat. The network analysis of the key metabolites regulated by Xihuang Pill was carried out by integrating biological network analysis tools, focusing on the key metabolic pathways, and exploring the potential targets of Xihuang Pill to improve hyperplasia of mammary glands. Compared with the control group, there were significant differences in the content of 49 differential metabolites in the tissues of the model group (P < 0.05). Xihuang Pills could significantly call back 17 metabolites such as L-alanine, threonine, indole-3-carboxylic aldehyde, lysine, arginine, alanylleucine, glycyltyrosine, γ-glutamyl leucine, vitamin B3, serine leucine, threonine leucine, isoleucine glutamic acid, γ-glutamyl tyrosine, decanoyl-L-carnitine, uric acid, leucylleucine, S-adenosyl-methionine. Further network analysis and literature research on the key metabolites regulated by Xihuang Pills showed that the AGE-RAGE signaling pathway may be one of the important pathways for Xihuang Pills to improve hyperplasia of mammary glands. STAT3, MAPK1, EGFR, CASP3, CASP8, PRKCA and JUN in the AGE-RAGE signaling pathway may be potential targets for Xihuang Pills to improve hyperplasia of mammary glands. The animal experiment operations involved in this paper follow the provisions of the Animal Ethics Committee of Gansu University of Traditional Chinese Medicine and pass the ethical review of animal experiments (approval number: 2022-705).

En bloc enucleation of the prostate with early apical release using a high-power (200 W) thulium device: studying a learning curve

SUMMARY OBJECTIVE: The aim of this study was to reveal the learning curve of early apical release en bloc laser prostatectomy using a high-power thulium (200 W) laser device. METHODS: We obtained data on the initial 60 patients who had thulium laser enucleation of the prostate by a single surgeon between October 2021 and August 2022 to treat the signs and symptoms of benign prostatic hyperplasia at our clinic. The cases were split into three groups, each consisting of 20 patients. Prostate volumes, prostate-specific antigen and hemoglobin levels, the International Prostate Symptom Score, Quality of Life scores, the International Index of Erectile Function-5 scores, and uroflowmetry parameters were documented preoperatively. The enucleation weight, the enucleation and morcellation times, as well as the efficiency, hospitalization, and catheterization durations were calculated. The patients were re-evaluated at 6 months postoperatively, examined for functional results, and compared to baseline conditions. RESULTS: Enucleation times, morcellation times, enucleation weight, and enucleation efficiency were significantly different among the groups. However, there was no statistically significant difference in total operative time and morcellation efficiency. In terms of postoperative statistics, the reduction in hemoglobin was significantly greater in Group 1 compared to Group 2. Six months after surgery, all groups had comparable validated ratings (International Prostate Symptom Score, Quality of Life, and the International Index of Erectile Function-5) on postoperative examinations. There were no long-term complications in either group throughout the perioperative period. CONCLUSION: Completing 40 first cases would be sufficient for managing the learning curve for early apical release en bloc thulium laser enucleation of the prostate.

Importância do diagnóstico por imagem em pacientes com sangramento uterino anormal / Importance of diagnostic imaging in patients with abnormal uterine bleeding

O sangramento uterino anormal é diagnóstico sindrômico comum no consultório do ginecologista e pode comprometer substancialmente a qualidade de vida. O objetivo no diagnóstico de sangramento uterino anormal é distinguir pacientes com causas estruturais (anatômicas), como pólipo, adenomiose, leiomioma, malignidade e hiperplasia, de pacientes que apresentam anatomia normal, nas quais o sangramento pode ser devido a alteração dos mecanismos de coagulação, distúrbios ovulatórios, distúrbios primários do endométrio, iatrogenia, ou ter outra causa não classificada. O diagnóstico se inicia a partir de anamnese detalhada e exame físico geral e ginecológico completos, seguidos da solicitação de exames complementares (laboratoriais e de imagem), conforme indicado. O exame de imagem de primeira linha para identificação das causas estruturais inclui a ultrassonografia pélvica. Histerossonografia, histeroscopia, ressonância magnética e amostragem endometrial para exame de anatomia patológica são opções que podem ser incluídas no diagnóstico a depender da necessidade. O objetivo deste artigo é apresentar a relevância dos exames de imagem na investigação das causas de sangramento uterino anormal.

Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office and may substantially affect quality of life. The aim in the diagnosis of abnormal uterine bleeding is to distinguish women with anatomic causes such as polyp, adenomyosis, leiomyoma, malignancy and hyperplasia from women with normal anatomy where the cause may be coagulopathy, ovulatory disorders, endometrial, iatrogenic and not otherwise classified. Diagnosis begins with a thorough history and physical examination followed by appropriate laboratory and imaging tests as indicated. The primary imaging test for the identification of anatomic causes include ultrasonography. Saline infusion sonohysterography, magnetic resonance, hysteroscopy, endometrial sampling are options that can be included in the diagnosis depending on the need. The aim of this article is to present the relevance of imaging exams in the investigation of the causes of abnormal uterine bleeding.

Determinación de valores de corte de 17 hidroxiprogesterona ajustados por edad gestacional para la pesquisa neonatal de la hiperplasia suprarrenal congénita / Assessment of gestational age-adjusted 17-hydroxyprogesterone cut-off values for neonatal screening of congenital adrenal hyperplasia

La pesquisa neonatal de hiperplasia suprarrenal congénita se realiza mediante la determinación de 17 hidroxiprogesterona (17OHP) en gotas de sangre seca en papel de filtro. Los bebés prematuros presentan valores más elevados que los bebés de término, siendo de utilidad contar con límites de corte apropiados. Nuestro objetivo fue actualizar los valores de corte de 17OHP ajustados por edad gestacional para la metodología en uso a nivel nacional por las jurisdicciones asistidas por el "Programa Nacional de Fortalecimiento de la Detección Precoz de Enfermedades Congénitas". La 17OHP se determinó utilizando el kit comercial de enzimo-inmunoanálisis (ELISA competitivo), Elizen Neonatal 17OHP Screening (Zentech, Bélgica). Se obtuvieron límites de corte utilizando percentiles de la distribución de los valores de 17OHP para cada edad gestacional. La sensibilidad obtenida fue 100%, especificidad 98,76 %, tasa de falsos positivos 1,24 % y el valor predictivo positivo 1,12 %. Destacamos la importancia de disponer de límites de corte adecuados a la población. La armonización de los mismos permitirá resultados comparables entre los programas regionales de pesquisa neonatal (AU)

Newborn screening for congenital adrenal hyperplasia is performed by the measurement of 17-hydroxyprogesterone (17OHP) in dried blood spots on filter paper. Premature infants have higher values than full-term infants, and appropriate cutoff values are useful. Our aim was to update the cut-off values of 17OHP adjusted for gestational age for the methodology used at a national level in regions assisted by the "National Program for Strengthening the Early Detection of Congenital Diseases". 17OHP was determined using the commercial enzyme-linked immunosorbent assay (competitive ELISA) kit, Elizen Newborn 17OHP Screening (Zentech, Belgium). Cut-off values were obtained using percentiles of the distribution of 17OHP values for each gestational age. Sensitivity was 100%, specificity 98.76%, false positive rate 1.24%, and positive predictive value 1.12%. It is important to have cut-off values that are adjusted to the population. Harmonization will allow for the comparison of results among regional newborn screening programs (AU)

Intraoral healing type of pyogenic granuloma (A benign vascular tumor): A case report

Pyogenic granulomas represent tumor-like lesions affecting the skin and the oral cavity. This classic definition can be somewhat misleading because such lesion is not associated with infection and lacks any clinical evidence of pus or histological evidence of actual granulation tissue. This case report describes a surgical excision of the growth to exclude angiomatous proliferation. The patient reported a chief complaint of localized gingival overgrowth since 4 months. Intraoral examination revealed an irregular, sessile exuberant growth in respect to labial aspect and interdental gingiva of 31, 32, and 33, measuring about 1.6 × 1.1 cm. Based on the clinical findings, the case was provisionally diagnosed as “pyogenic granuloma“. A treatment was planned for the patient. A surgical excision was done irt 31, 32, 33, and the tissue was sent for histopathological examination, which was suggestive of a healing type of pyogenic granuloma.

Mutation distributions among patients with congenital adrenal hyperplasia from five regions of Brazil: a systematic review

ABSTRACT Congenital adrenal hyperplasia due to 21-hydroxylase deficiency is an autosomal recessive disorder caused by CYP21A2 gene mutations, and its molecular diagnosis is widely used in clinical practice to confirm the hormonal diagnosis. Hence, considering the miscegenation of the Brazilian population, it is important to determine a mutations panel to optimise the molecular diagnosis. The objective was to review the CYP21A2 mutations' distribution among Brazilian regions.Two reviewers screened Brazilian papers up to February 2020 in five databases. The pair-wise comparison test and Holm method were used in the statistical analysis. Nine studies were selected, comprising 769 patients from all regions. Low proportion of males and salt-wasters was identified in the North and Northeast regions, although without significant difference. Large gene rearrangements also had a low frequency, except in the Center-West and South regions (p < 0.05). The most frequent mutations were p.I172N, IVS2-13A/C>G, p.V281L and p.Q318X, and significant differences in their distributions were found: p.V281L was more frequent in the Southeast and p.Q318X in the Center-West and Northeast regions (p < 0.05). Thirteen new mutations were identified in 3.8%-15.2% of alleles, being more prevalent in the North region, and six mutations presented a founder effect gene. Genotype-phenotype correlation varied from 75.9%-97.3% among regions. The low prevalence of the salt-wasting form, affected males and severe mutations in some regions indicated pitfalls in the clinical diagnosis. The good genotype-phenotype correlation confirms the usefulness of molecular diagnosis; however, the Brazilian population also presents significant prevalence of novel mutations, which should be considered for a molecular panel.

Surgical Treatment of Oral Fibrous Hyperplasia with Diode Laser: An Integrative Review / Tratamiento Quirúrgico de la Hiperplasia Fibrosa Oral con Láser de Diodo: Una Revisión Integradora

This study aimed to carry out an integrative review of the use of diode lasers in the treatment of oral fibrous hyperplasia in order to observe surgical efficacy, healing process, and main microscopic findings. The following databases-PubMed/MEDLINE, Embase, Virtual Health Library, Scopus, Web of Science, and gray literature-were searched without regard to the time of year or language. Diode laser treatment cases described in case reports and case series were included, but those who did not undergo microscopic analysis to confirm the diagnosis or who did not provide postoperative information were excluded. Twelve studies (64 patients) were included. Prevalence was observed for females (68.75 %, n=44). In view of the diagnosis, there was a prevalence of focal fibrous hyperplasia (79.68 %, n=51), followed by inflammatory fibrous hyperplasia (20.31 %, n=13). For surgical removal, a diode laser was used with a wavelength ranging from 808 to 960 nm, in continuous mode, and an average power of 2830 mW. In general, there were no intercurrences in the trans and postoperative periods and wound healing occurred by second intention, with excellent evolution. High-powered diode lasers can be an excellent therapeutic option for oral hyperplastic lesions. Long-term clinical trials should be conducted to determine laser setting parameters in various oral lesions.

El objetivo de este estudio fue realizar una revisión integradora sobre el uso del láser de diodo en el tratamiento de la hiperplasia fibrosa oral, con el fin de visualizar la eficacia quirúrgica, el patrón de cicatrización y el análisis de los principales resultados microscópicos. Se realizó una búsqueda sin restricciones de año e idioma en PubMed/MEDLINE, Embase, Virtual Health Library, Scopus, Web of Science y literatura gris. Se incluyeron reportes de casos y series de casos que brindaron información sobre pacientes diagnosticados con lesiones hiperplásicas orales tratados con láser de diodo, excluyendo aquellos a los que no se les había realizado análisis microscópico para confirmar el diagnóstico, así como aquellos que no brindaron información postoperatoria. Se incluyeron doce estudios (64 pacientes). Se observó prevalencia en el sexo femenino (68,75 %, n=44). Ante el diagnóstico, predominó la hyperplasia fibrosa focal (79,68 %, n=51), seguida de la hiperplasia fibrosa inflamatoria (20,31 %, n=13). Para la remoción quirúrgica se utilizó un láser de diodo con una longitud de onda de 808 a 960 nm, en modo continuo, y una potencia promedio de 2830 mW. En general, no hubo intercurrencias en el trans y postoperatorio y la cicatrización de la herida ocurrió por segunda intención, con excelente evolución. El uso de láseres de diodo de alta potencia puede ser una excelente alternativa terapéutica para las lesiones hiperplásicas orales. Se deben realizar más estudios clínicos a largo plazo para determinar los parámetros de ajuste del láser en diferentes lesiones orales.

Effects of dutasteride and tamsulosin on penile morphology in a rodent model

ABSTRACT Purpose To evaluate the penile morphology after the isolated and combined administration of dutasteride and tamsulosin in a rodent model. Materials and Methods Forty male rats were assigned into the following groups: Control group (C, receiving distilled water, n=10); Dutasteride group (D, receiving 0.5 mg/Kg/day of dutasteride, n=10); Tamsulosin group (T, receiving 0.4 mg/Kg/day of tamsulosin, n=10); and Dutasteride associated with Tamsulosin group (DT, receiving both drugs n = 10). All drugs were administered via oral gavage. After 40 days, the animals were submitted to euthanasia and their penises were collected for histomorphometric analyses. Data were compared using one-way ANOVA followed by Bonferroni's post-test, considering p<0.05 as significant. Results The sinusoidal space and smooth muscle fiber surface densities (Sv), and the cross-sectional penile areas of rats in groups D, T and DT were reduced in comparison to controls with the most notable reductions in the combined therapy group. The connective tissue and elastic system fibers Sv were augmented in groups D, T and DT in comparison with the control group, again with the most pronounced changes observed in animals receiving the combined therapy. Conclusion Both treatments with dutasteride or tamsulosin promoted penile morphometric modifications in a rodent model. The combination therapy resulted in more notable modifications. The results of this study may help to explain the erectile dysfunction observed in some men using these drugs.

Contiguous squamous proliferations in syringocystadenoma papilliferum: A retrospective study of 14 cases

Background: Syringocystadenoma papilliferum is a benign adnexal neoplasm. Contiguous squamous proliferation has been rarely described in syringocystadenoma papilliferum. Aims: This study aimed to evaluate the spectrum and pathogenesis of contiguous squamous proliferation in syringocystadenoma papilliferum. Materials and Methods: All cases of syringocystadenoma papilliferum diagnosed over the past 12 years were screened for contiguous squamous proliferation. Cases with associated nevus sebaceous were excluded from the study. Immunohistochemistry for GATA3, CK7, BRAFV600E and p16 was performed. PCR for human papilloma virus, type 16 and 18, was carried out. Results: Of a total of 30 cases, 14 cases showed associated contiguous squamous proliferation which included four cases of verrucous hyperplasia, six cases with papillomatosis, two cases with mild squamous hyperplasia and one case each of Bowen’s disease and squamous cell carcinoma. In the cases with non-neoplastic contiguous squamous proliferations, the squamous component did not express CK7 or GATA3. However, the squamous component of premalignant and malignant lesions expressed CK7 and GATA3 concordant with the adenomatous component. BRAF was positive in adenomatous component in five cases while the contiguous squamous proliferation component was negative for BRAF in all but one case. p16 was negative in both components of all cases and PCR for human papilloma virus was negative in all cases. Limitations: Due to the rarity of disease, the sample size of our study was relatively small with two cases in the 2nd group, that is, syringocystadenoma papilliferum with malignant contiguous squamous proliferation. Detailed molecular studies such as gene sequencing were not performed. Conclusion: Syringocystadenoma papilliferum with contiguous squamous proliferation is underreported, and most commonly displays verrucous hyperplasia. The premalignant and malignant contiguous squamous proliferations likely arise from syringocystadenoma papilliferum while the hyperplastic contiguous squamous proliferations likely arise from the adjacent epidermis. Relationship with high-risk human papilloma virus is unlikely. However, further molecular analysis of larger number of cases is required to establish the pathogenesis.

Adenoma hepatocelular con captación de 18 flúor deoxiglucosa en PET-TC SCAN. Una "mini-review" e informe de un nuevo caso / 18-fluoro-deoxyglucose uptake on PET-CT in hepatocellular adenoma. A mini review with a new case Report

RESUMEN La captación de 18 FDG en PET-TC por un adenoma hepatocelular (HCA) es poco frecuente. Esta situación genera dudas en cuanto a los diagnósticos diferenciales y tratamiento. El objetivo de este artículo fue realizar una mini revisión de los últimos 37 años de HCA con avidez por el 18FDG y presentar un nuevo caso. Sobre la base de un estudio realizado por otros autores entre 1984 y 2014, se amplía la búsqueda utilizando las mismas palabras clave hasta el año 2021. Se analizan los datos relevantes. Entre 1984 y 2021 detectamos 38 casos en 37 años. Fue más frecuente en mujeres en edad reproductiva. Los subtipos H-HCA e I-HCA fueron los más frecuentes. El tratamiento quirúrgico fue el más empleado. La diferenciación celular y los trastornos metabólicos de la glucosa y de los lípidos favorecerían la captación de 18FDG. La resección hepática ofrecería mayores garantías permitiendo el estudio completo de la lesión.

ABSTRACT Hepatocellular adenoma (HCA) uptake of 18FDG uptake on PET-CT is rare. This situation poses doubts about the differential diagnoses and treatment. The aim of this article is to perform a mini review of 18FDG avid HCA over the past 37 years and to describe a new case presentation. Based on a study conducted by other authors between 1984 and 2014, we extended the search until 2021 using the same keywords. The relevant data were analyzed. Between 1984 and 2021 we detected 38 cases in 37 years. HCAs were more common in women of childbearing age. The most common types were H-HCA an I-HCA. Surgical resection was the treatment most used. Cell differentiation and glucose and lipid metabolic diseases would favor 18FDG uptake. Liver resection provides better outcomes, allowing for a complete examination of the lesion.

Inflammatory Fibrous Hyperplasia Associated with Chondroid Metaplasia - Report and Morphological Analysis of Five Cases

Inflammatory fibrous hyperplasia (IFH) is a common reactive lesion in dental prostheses users that may be associated with chondroid metaplasia (CM). Metaplasia is an adaptive cellular process that may be caused by trauma. We reported here five cases of IFH associated with CM and analyzed morphologically the deposition of collagen in these lesions. Patients had a mean age of 58.8 years-old and were ill-fitting dental prostheses users. They presented nodular lesions located in the anterior maxilla. Microscopically, it was observed hyperplastic fibrous connective tissue with chronic inflammatory infiltrate and hyaline cartilage. No morphological differences were observed in collagen deposition under light microscopy, but quantitative analysis revealed a significantly higher collagen deposition at the connective tissue near CM (p = 0.015). IFH associated with CM affects ill-fitting dental prostheses users. The presence of CM is not significant to the lesion prognosis. However, its formation and the higher collagen deposition near it reinforces the IFH reactive origin.

La hiperplasia fibrosa inflamatoria (HFI) es una lesión reactiva común en los usuarios de prótesis dentales que puede estar asociada con la metaplasia cartilaginosa (MC). La metaplasia es un proceso celular adaptativo que puede ser causado por un trauma. El presente informe analizó cinco casos de HFI asociados a MC y se analizaron morfológicamente la deposición de colágeno en estas lesiones. Los pacientes tenían una edad media de 58,8 años y eran usuarios de prótesis dentales mal adaptadas. Se observaron lesiones nodulares localizadas en el la parte anterior del maxilar Microscópicamente se observó tejido conectivo fibroso hiperplásico con infiltrado inflamatorio crónico y cartílago hialino. No se observaron diferencias morfológicas en la deposición de colágeno bajo microscopía óptica, pero el análisis cuantitativo reveló una deposición de colágeno significativamente mayor en el tejido conectivo cerca de MC (p = 0,015). La HFI asociada con la MC afecta a los usuarios de prótesis dentales mal adaptadas. La presencia de MC no es significativa para el pronóstico de la lesión. Sin embargo, su formación y la mayor deposición de colágeno cerca de MC refuerza el origen reactivo de HFI.

Normal ambulatory blood pressure in young adults with 21-hydroxylase enzyme deficiency undergoing glucocorticoid replacement therapy

ABSTRACT Objective: Herein, we compared ambulatory blood pressure (ABP) between young adults with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase enzyme (21OHase) deficiency and a control group. Additionally, we analyzed correlations between the glucocorticoid dose and androgen levels and ABP parameters. Subjects and methods: This case-control study included 18 patients (6 males and 12 females) and 19 controls (8 males and 11 females) matched by age (18-31 years). ABP monitoring was used to estimate blood pressure (BP) over a 24-h period. Results: No difference was noted between patients and controls in terms of systolic BP (males, 115.5 ± 5.6 vs. 117.0 ± 9.3, P = 0.733; and females, 106.4 ± 7.9 vs. 108.4 ± 7.6, P = 0.556, respectively) and diastolic BP during 24 h (males, 62.8 ± 7.5 vs. 66.2 ± 5.6, P = 0.349; and females, 62.7 ± 4.9 vs. 62.3 ± 4.9, P = 0.818, respectively). Systolic and diastolic BP and pulse pressure during daytime and nocturnal periods were similar between patients and controls. Furthermore, no differences were detected in the percentage of load and impaired nocturnal dipping of systolic and diastolic BP between patients and controls during the 24-h period. Additionally, the glucocorticoid dose (varying between r = −0.24 to 0.13, P > 0.05) and androgens levels (varying between r = 0.01 to 0.14, P > 0.05) were not associated with ABP parameters. Conclusion: No signs of an elevated risk for hypertension were observed based on ABP monitoring in young adults with CAH attributed to 21OHase deficiency undergoing glucocorticoid replacement therapy.

A prospective study to evaluate the efficacy and adverse effects of alpha-blockers in the management of benign prostatic hyperplasia

Background: Benign prostatic hyperplasia (BPH) is the most common cause for the lower urinary tract symptoms in men. The conservative management of BPH comprises of alpha blockers, especially selective alpha 1 adrenergic blockers for symptomatic relief. Aims and Objectives: We aimed to evaluate the efficacy and adverse effects of alpha blockers in managing BPH. Materials and Methods: After getting approval from the Institutional Human Ethics Committee and consent from subjects, this prospective, randomized, and controlled trial was conducted. In this study, patients under inclusion criteria were divided into two groups. Group I received silodosin 8 mg once daily for 8 weeks. Group II received tamsulosin 0.4 mg once daily for 8 weeks. Primary outcome measure was reduction in international prostate symptom score (IPSS). Adverse events during study period were recorded. Results: A total of 90 patients were enrolled in this study. Ten patients were excluded and remaining 80 patients were divided as 40 in Group I (Silodosin) and 40 in Group II (Tamsulosin), patients were followed up for 8 weeks. As primary outcome, the IPSS at 8th week was significantly <0 week, that is, baseline in both the groups. The comparison of IPSS within Group I and Group II at 0 week and 8th week was significant (P < 0.05). The quality of life comparison within Group I and Group II at 0 week and 8th week was significant (P < 0.05). Both the drugs were well tolerated. Retrograde ejaculation and diarrhea were noted with silodosin (Group I), dizziness and orthostatic hypotension were noted with Tamsulosin (Group II). Conclusion: The obtained results showed that both silodosin and tamsulosin produced significant improvement in IPSS and quality of Life in BPH patients. In silodosin group, retrograde ejaculation and diarrhea were notable adverse effects and in tamsulosin group, dizziness and orthostatic hypotension were noted.

El objetivo de este artículo es reportar un caso de FFH en el borde lateral a ambos lados de la lengua asociado al uso del aparato Hyrax en un paciente hebiátrico, cuyo principal motivo de consulta era la molestia masticatoria. Este caso fue diagnosticado clínicamente y por análisis histopatológico y tratado mediante escisión quirúrgica así como la retirada de los aparatos de Hyrax. La atención de seguimiento permitió la recuperación de la calidad de vida del paciente

Clinicopathologic features and imaging manifestations of focal nodular hyperplasia-like nodules in cirrhosis liver / 中华肝胆外科杂志

A kind of focal lesions called focal nodular hyperplasia-like nodules (FNH-LNs) was found in liver cirrhosis, especially in alcoholic cirrhosis, which is similar to focal nodular hyperplasia in histology. The imaging features of FNH-LNs show hyperenhancement in arterial phase, hypoenhancement in portal venous phase or delayed phase. FNH-LNs are easily misdiagnosed as hepatocellular carcinoma (HCC). With reviewing the relating articles in China and abroad, this article summarizes the etiology, clinicopathological features and imaging manifestations of FNH-LNs, so as to distinguish FNH-LNs and HCC in cirrhosis and guide selection of treatment.

Analysis of 17 cases of Vaterian system adenomyomatous hyperplasia / 中华肝胆外科杂志

Objective:To study the features of adenomyomatous hyperplasia (AH) of the Vaterian system (common bile duct and ampulla of Vater) to help in the diagnosis and management of this disease.Methods:A retrospective analysis on the data of 17 patients who had a postoperative pathological diagnosis of AH of the Vaterian system treated from January 2005 to December 2021 at the First Medical Center of the PLA General Hospital was carried out with 12 males and 5 females, aged (58.4±11.3) years. The clinical presentations, treatment and postoperative pathology of these patients were analyzed. Patients with dysplasia of the tubular mucosal epithelium in the non-cancerous area around the AH under microscopy were included in the AH with dysplasia group ( n=8), and those without dysplasia were included in the control group ( n=9). The clinical characteristics of the two groups were compared. Results:The main clinical symptoms were abdominal pain in 8 patients, jaundice in 7 patients and fever in 2 patients. Preoperative imaging showed 10 cases of occupying lesions and 6 cases of abnormally dilated intrahepatic and extrahepatic bile ducts without obvious lesions or stones or biliary tract injury stenosis. Sixteen patients underwent radical pancreaticoduodenectomy, and 1 patient underwent extrahepatic biliary resection combined with choledochojejunostomy for bile duct obstruction due to biliary stones, 3 patients had combined malignant tumors, 1 patient had a carcinoma of AH origin at the ampulla of Vater, and the other 2 patients had neoplastic lesions in the mucosal epithelium adjacent to the AH (cholangiocarcinoma and ampullary carcinoma, respectively). There were no significant differences in age, gender, bile duct stones, cholangitis, combined carcinoma and liver function indexes between the two groups of patients with AH of the Vaterian system (all P>0.05). Conclusion:Adenomyomatous hyperplasia of the Vaterian system was difficult to distinguish preoperatively from malignant tumors basing on its clinical presentations or imaging findings. Such patients are recommended to be treated surgically.

Analysis of risk factors for endometrial atypical hyperplasia and endometrial cancer / 中国医师杂志

Objective:To explore the high-risk factors of endometrial cancer (EC) and provide clinical basis for early screening, diagnosis and treatment of EC.Methods:From January 2017 to December 2022, patients admitted to Shanxi Provincial Maternal and Child Health Hospital for hysteroscopic surgery or diagnostic curettage due to abnormal uterine bleeding, postmenopausal vaginal bleeding and other related symptoms were selected as the research objects. After histopathological examination, they were diagnosed with no atypical endometrial hyperplasia (EH), atypical endometrial hyperplasia (AEH), and EC as the research subjects. The general data of patients′ records, vaginal ultrasound, cervical liquid-based cytology test (LCT), carbohydrate antigen 125 (CA125) and pelvic magnetic resonance imaging were collected, and a case-control study was conducted and the risk factors of AEH and EC were explored using univariate and multivariate logistic regression analysis.Results:This study included a total of 420 cases, including 215 in the EH group, 69 in the AEH group, and 136 in the EC group. Through the comparison of various indicators among the three groups and the results of univariate factor logistic regression analysis, age, menopause, previous delivery history, hypertension, diabetes, color ultrasound showed endometrial thickening (>10 mm), uneven endometrial echo, abnormal echo mass in the uterine cavity, endometrial blood flow signals, cervical LCT examination showed that atypical glandular cells were related to the occurrence of EC, with a statistically significant difference (all P<0.05). The results of multivariate logistic regression analysis showed that age>48 years ( OR=3.65, 95% CI: 2.06-6.45), menopause ( OR=3.19, 95% CI: 1.46-6.98), uneven endometrial echo ( OR=4.08, 95% CI: 2.26-7.36), and intrauterine blood flow signal ( OR=2.91, 95% CI: 1.52-5.58), cervical LCT suggests that atypical glandular cells ( OR=4.25, 95% CI: 1.38-13.11) were independent risk factors for EC and precancerous lesions (all P<0.05). Conclusions:For patients with clinical symptoms such as abnormal uterine bleeding or postmenopausal bleeding, timely and focused screening based on whether they have EC risk factors is an economic, safe, and effective method for early detection and treatment of EC.

Effects of Qingruxiao granules combined with tamoxifen on mammary hyperplasia and its effects on serum hypoxia inducible factor-1α, angiopoietin-2 and prolactin levels / 中国基层医药

Objective:To investigate the efficacy of Qingruxiao granules combined with tamoxifen in the treatment of breast hyperplasia and its effect on serum hypoxia-inducible factor-alpha (HIF-α), angiopoietin-2 (Ang-2) and prolactin (PRL) levels. Methods:Ninety-eight patients with breast hyperplasia admitted to Xi'an No.3 Hospital from June 2020 to January 2022 were retrospectively included in this study. They were divided into control and observation groups ( n = 49/group) according to different treatments. The control group was treated with tamoxifen alone. The observation group was treated with Qingruxiao granules combined with tamoxifen. Clinical efficacy, symptom score, ultrasound parameters (glandular layer thickness, longest diameter of mass, maximum diameter of hypoechoic area, inner diameter of lactating tube), endocrine hormone levels (estradiol, progesterone, and prolactin), HIF-α, and Ang-2 pre- and post-treatment, as well as the incidence of adverse reactions were compared between the two groups. Results:Total response rate in the observation group was significantly higher than that in the control group [93.88% (4/49) vs. 77.55%, χ2 = 5.33, P < 0.05). After treatment, breast mass score, breast pain, systemic accompanying symptom, and nipple discharge in the observation group were (1.34 ± 0.29) points, (1.02 ± 0.36) points, (0.68 ± 0.17) points, (0.97 ± 0.15) points, respectively, which were significantly lower than (1.57 ± 0.23) points, (1.45 ± 0.41) points, (0.95 ± 0.26) points, and (1.28 ± 0.26) points, respectively, in the control group ( t = 4.35, 5.52, 6.08, 7.23, all P < 0.001). The glandular layer thickness, the longest diameter of mass, the maximum diameter of hypoechoic area, and the inner diameter of lactating duct in the observation group were (9.45 ± 1.67) mm, (11.46 ± 3.68) mm, (14.37 ± 4.22) mm, and (1.23 ± 0.39) mm, respectively, which were significantly lower than (11.26 ± 2.51) mm, (16.33 ± 4.01) mm, (19.87 ± 5.01) mm, (1.54 ± 0.48) mm in the control group ( t = 4.20, 2.26, 5.88, 3.51, all P < 0.001). Serum estradiol and prolactin levels in the observation group were (122.35 ± 29.76) ng/L and (205.64 ± 36.42) IU/L, respectively, which were significantly lower than (139.76 ± 30.48) ng/L and (251.49 ± 41.87) IU/L in the control group ( t = 2.86, 5.78, both P < 0.05). Serum progesterone level in the observation group was (9.22 ± 1.57) μg/L, which was significantly higher than (7.18 ± 1.21) μg/L in the control group ( t = -7.20, P < 0.05). Serum HIF-α and Ang-2 levels in the observation group were (0.15 ± 0.05) ng/L and (0.98 ± 0.11) ng/L, respectively, which were significantly lower than (0.24 ± 0.07) ng/L and (1.49 ± 0.22) ng/L in the control group ( t = 7.32, 14.51, both P < 0.001). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Qingruxiao granules combined with tamoxifen can effectively improve clinical symptoms, reduce tumor size, regulate endocrine hormone levels, decrease the expression of angiogenic factors in patients with breast hyperplasia, and is highly safe.
