Update on the oncologic and obstetric outcomes of medroxyprogesterone acetate treatment for atypical endometrial hyperplasia and endometrial cancer.

AIMS: To evaluate the safety and effectiveness of high-dose oral medroxyprogesterone acetate (MPA) therapy as a fertility-sparing treatment for patients diagnosed with atypical endometrial hyperplasia (AEH) and endometrioid carcinoma G1 without myometrial invasion (G1EC). Particular attention was given to the extended administration and readministration of MPA for patients with persistent disease following initial treatment and those with recurrence. METHODS: We conducted a retrospective analysis of data from 79 patients who underwent daily oral MPA treatment between 2005 and 2024 at Nagoya University Hospital. Patient characteristics, treatment outcomes, factors contributing to recurrence, and post-MPA therapy pregnancies were examined. RESULTS: MPA therapy achieved a remarkable complete response (CR) rate of 91.1%. The median time to achieve CR was 26.0 and 40.0 weeks for AEH and G1EC patients, respectively. Importantly, 27 patients (39.7%) attained CR after more than 6 months of treatment, including 8 patients (11.8%) who achieved CR after more than a year of treatment. The recurrence rates were 52.9% for AEH and 64.7% for G1EC. Twenty eight patients resumed MPA treatment, and 23 achieved second CR. Notably, recurrence was not associated with clinical factors such as age, body mass index, or post-CR pregnancy. Among patients who attempted pregnancy after achieving CR, 22 live births were successfully achieved. CONCLUSIONS: High-dose oral MPA therapy demonstrated both safety and efficacy for preserving fertility in patients with AEH and G1EC, resulting in a high CR rate. MPA extension and readministration proved to be beneficial strategies for managing patients with recurrence and persistent disease following initial treatment.

Artificial intelligence model for enhancing the accuracy of transvaginal ultrasound in detecting endometrial cancer and endometrial atypical hyperplasia.

OBJECTIVES: Transvaginal ultrasound is typically the initial diagnostic approach in patients with postmenopausal bleeding for detecting endometrial atypical hyperplasia/cancer. Although transvaginal ultrasound demonstrates notable sensitivity, its specificity remains limited. The objective of this study was to enhance the diagnostic accuracy of transvaginal ultrasound through the integration of artificial intelligence. By using transvaginal ultrasound images, we aimed to develop an artificial intelligence based automated segmentation model and an artificial intelligence based classifier model. METHODS: Patients with postmenopausal bleeding undergoing transvaginal ultrasound and endometrial sampling at Mayo Clinic between 2016 and 2021 were retrospectively included. Manual segmentation of images was performed by four physicians (readers). Patients were classified into cohort A (atypical hyperplasia/cancer) and cohort B (benign) based on the pathologic report of endometrial sampling. A fully automated segmentation model was developed, and the performance of the model in correctly identifying the endometrium was compared with physician made segmentation using similarity metrics. To develop the classifier model, radiomic features were calculated from the manually segmented regions-of-interest. These features were used to train a wide range of machine learning based classifiers. The top performing machine learning classifier was evaluated using a threefold approach, and diagnostic accuracy was assessed through the F1 score and area under the receiver operating characteristic curve (AUC-ROC). RESULTS: 302 patients were included. Automated segmentation-reader agreement was 0.79±0.21 using the Dice coefficient. For the classification task, 92 radiomic features related to pixel texture/shape/intensity were found to be significantly different between cohort A and B. The threefold evaluation of the top performing classifier model showed an AUC-ROC of 0.90 (range 0.88-0.92) on the validation set and 0.88 (range 0.86-0.91) on the hold-out test set. Sensitivity and specificity were 0.87 (range 0.77-0.94) and 0.86 (range 0.81-0.94), respectively. CONCLUSIONS: We trained an artificial intelligence based algorithm to differentiate endometrial atypical hyperplasia/cancer from benign conditions on transvaginal ultrasound images in a population of patients with postmenopausal bleeding.

Papillary endothelial hyperplasia (Masson's tumor) of the breast: A diagnostic challenge.

Papillary endothelial hyperplasia (PEH) or Masson's tumor is a rare benign vascular tumor that usually appears in the soft tissues of the head and neck, trunk and extremities, being extremely rare in the breast. Its diagnosis can be a challenge, especially in the follow-up of patients with previous disease of breast carcinoma. We present the case of a 65-year-old patient, with a history of bilateral breast cancer and reconstruction with implants, who presented a Masson's tumor during follow-up. An ultrasound scan was performed, showing a well-circumscribed mass in the left breast, located in the posterior contour of the implant. Subsequently, magnetic resonance imaging (MR) depicted an enhancing tumor, without infiltration of adjacent structures. Finally, the definitive anatomopathological diagnosis was obtained after surgical excision.

An arteriovenous fistula model: Carotid artery-posterior facial vein fistula in rats.

OBJECTIVE: To describe an alternative arteriovenous fistula (AVF) model involving anastomosis of the common carotid artery (CCA) with the posterior facial vein (PFV). METHODS: Twenty-two male Sprague-Dawley rats (age 6-8 weeks) were used to establish the AVF model involving end-to-side anastomosis of PFV and CCA. The peak velocity of the CCA and the diameter of the outflow vein were recorded at 7, 14, and 42 days after the operation using Doppler ultrasound. Pathological examination of the intimal lesions was performed at 14 and 42 days after operation. RESULTS: One rat died within 24 h after surgery related to anesthesia. The patency rates at days 7, 14, and 42 were 85.7%, 81%, and 81%, respectively. The diameter of the carotid artery in rats is approximately 0.8 mm. The diameter of the outflow vein was increased by 1.7-fold and 2.2-fold at 7 days (1.1 ± 0.118 mm) and 14 days (1.4 ± 0.073 mm). At 42 days (1.96 ± 0.101 mm) after operation, the diameter was 3-fold greater compared to the unoperated control rat. The peak systolic flow velocity of the carotid artery at 7 days (593 ± 17.36 mm/s) and 14 days (767 ± 13.64 mm/s) after surgery was significantly greater compared to the control rat (314 ± 15.13 mm/s). The rate of increase was fastest at 7 days and leveled off from 14 to 42 days (875 ± 26 mm/s) after surgery. At 14 days, the intima area showed a nearly 50-fold increase (230 ± 9.93 µm2 × 103) compared to control (area 5 ± 0.37 µm2 × 103). Comparing 6 weeks with 2 weeks (280 ± 10.54 µm2 × 103) after surgery, the intima area increased 1.2 times. CONCLUSION: The CCA-PFV fistula in rats is a viable alternative AVF model.

Characteristics of Bilateral Adrenal Lesions: Experience from an Indian Tertiary Care Centre.

Introduction: The aetiologies in unilateral and bilateral adrenal lesions can be different with different clinical implications and management guidelines, the latter having aetiologies like hyperplasia, infections, infiltrative lesions and neoplasia. Bilateral tumours are more likely to have hereditary/syndromic associations. There is limited data on the clinical and pathological profile of bilateral adrenal lesions. Methods: This was a retrospective study where patients with bilateral adrenal lesions were selected from a total of 266 patients with adrenal lesions who presented to our institute between January 2016 and August 2022. The demographic, laboratory and imaging data were retrieved from the Hospital Information System and patient case files. Results: The study included 51 patients; the mean age at presentation was 51.15 years (range 14 to 82 years). Forty-eight patients (94.1%) were symptomatic at presentation with an average duration of symptoms being 10.68 months (range 10 days to 1 year). The most common presentation was adrenal insufficiency in 18 cases (38%), followed by fever in 17 cases (36%). The commonest aetiology, as revealed on histopathology, was histoplasmosis (n = 22, 43%), followed by pheochromocytoma (n = 11, 21.5%), metastases (n = 6, 11.7%), adrenal hyperplasia (n = 5, 9.8%), adrenocortical adenoma (n = 1, 1.9%), lymphoma (n = 3, 5.8%), neuroblastoma (n = 1, 1.9%), myelolipoma (n = 1, 1.9%) and tuberculosis (n = 1, 1.9%). Histoplasmosis and metastatic lesions were commonly seen in older people, and pheochromocytoma was associated with young age. 6/11 patients with a diagnosis of bilateral pheochromocytoma were associated with family history, genetic mutation and extra-adrenal involvement. Conclusion: The approach to bilateral adrenal lesions differs from that of unilateral lesions due to differences in aetiologies and the more significant role of genetics in some bilateral tumours. The age at presentation, presenting symptoms, lesion size and biochemical features help delineate varied underlying aetiologies.

The Clinical Predictors of Malignancy in the Prostate Gland and Their Correlation With Prostate-Specific Antigen (PSA) Levels.

Background and objective The prostate gland, which plays a crucial role in the male reproductive system, has a complex structure and function. Prostate enlargement, often benign but occasionally malignant, poses significant health concerns, particularly in aging populations. Prostate-specific antigen (PSA) serves as a vital biomarker, reflecting changes in prostate architecture and aiding diagnostic stratification. Elevated PSA levels correlate with prostate pathology and standard grading systems such as Gleason grading help guide treatment decisions. This study aimed to investigate the correlation between prostate enlargement, PSA levels, and Gleason grades, particularly within the Indian context. Materials and methods This study was conducted over one and a half years at the Department of Pathology, Rajendra Institute of Medical Sciences, Ranchi, and involved 100 cases of clinically enlarged prostates. Clinical data, including age, symptoms, and relevant features, were collected, and histopathological analysis was performed on biopsy specimens. Statistical analysis was conducted using Microsoft Excel and SPSS Statistics version 20.0 (IBM Corp., Armonk, NY). Results Our study identified possible links between several factors and prostate conditions. Non-vegetarian diets showed a potential association with increased adenocarcinoma prevalence (p = 0.179). Urinary symptoms like hesitancy, incomplete voiding, retention, frequency, and urgency were significantly more common in men with adenocarcinoma (p<0.05). Additionally, bone pain and abnormal digital rectal examination (DRE) findings strongly correlated with adenocarcinoma (p<0.001). As expected, age showed a positive correlation with prostate weight and PSA levels (p<0.01). Interestingly, bone pain was associated with a lower likelihood of other prostate symptoms (p = 0.023). Conclusions Our findings provide key insights into the clinical factors associated with prostate pathology and highlight the need for a comprehensive approach to diagnosis in these patients, integrating clinical evaluation and histopathological assessment.

Syzygium malaccense leaves methanol extract modulate some biochemical and inflammatory markers and prostate histology of testosterone-estradiol valerate induced benign prostatic hyperplasia in rats.

Objective: The effect of Syzygium malaccense methanol leaf extract (SMLE) on some parameters of testosterone-estradiol valerate induced benign prostatic hyperplasia (BPH) in rats was assayed. Materials and Methods: Thirty male albino rats were used and they were grouped as: Control: received 1 mL/kg olive oil (oral and subcutaneous); BPH: received subcutaneously 9 mg/kg dihydrotestosterone (DHT)+0.9 mg/kg estradiol valerate (ESV) and orally 1 ml/kg olive oil; finasteride: received 9 mg/kg of DHT+0.9 mg/kg ESV (subcutaneously) and 5 mg/kg finasteride (orally) and test groups 1 and 2: received 9 mg/kg of DHT+0.9 mg/kg ESV (subcutaneously) and 200 and 400 mg/kg SMLE (orally). The duration of the treatment was 28 days. Results: The BPH group had increased prostatic total proteins, oxidative stress, interleukin 8, tumor necrosis factor-α, prostate weights, serum concentrations of prostate specific antigen, estradiol, follicle stimulating hormone, and C-reactive protein, dyslipidaemia, altered prostate histology and hormonal levels but had no significant change (p>0.05) in haematological indices relative to the control. Finasteride or S. malaccense modulated most of these parameters as corroborated by prostate histology. Acute toxicity study indicated the non-toxicity of SMLE. SMLE showed strong in vitro antioxidant activity which corroborated its in vivo antioxidant activity. Conclusion: The study showed that S. malaccense could be useful in the management of BPH.

Adenomatous hyperplasia induced by chronic cherry pit retention mimicking an endobronchial tumor-case series and systematic review of literature.

Introduction: Endobronchial foreign body aspiration is not common in adults, but it is a life-threatening event. Recurrent pneumonias by chronic retention of foreign body often lead to initial medical presentation of the patient. However, lymphoplasmacellular bronchitis with adenomatous hyperplasia and squamous epithelium metaplasia with complete or partial blockage of lobar bronchus mimicking lung tumor is rare in literature, and this particular condition is often misdiagnosed. Case presentation: we report our experience in the diagnostic and management of two elderly patients with recurrent pneumonia, admitted in hospital for further examination. In both patients, with no history of aspiration, the cherry pit was detected during bronchoscopy and recanalization with flexible cryoprobe, surrounded by purulent secretion, occluding completely the right upper lobe in the first case, and partially the left lower lobe associated with persistent actinomycosis in the second case, with signs of local inflammation, bronchial adenomatous hyperplasia mimicking lung tumor at initial bronchoscopic examination. Histology showed a lymphoplasmacellullar bronchitis with adenomatous hyperplasia and squamous epithelium metaplasia because of chronic retention of foreign body. Conclusion: Bronchoscopy examination should be considered in cases where there is an unresolved chronic cough with recurrent pneumonia or persistent actinomycosis in patients with high risk. Cryoprobe is a safe and feasible approach for treatment of airway obstructions due to chronic foreign body retention. Furthermore, relevant findings are discussed here, along with a review of the pathologic alterations and treatment modalities seen in chronic retention of foreign body and airway injury.

Non Typical Type 1 Diabetes Mellitus Onset in a Child With Salt-Wasting Congenital Adrenal Hyperplasia.

Type 1 diabetes mellitus (T1DM) and congenital adrenal hyperplasia (CAH) are 2 complex endocrine disorders with neighboring genetic loci. We present a case of T1DM onset in a 6-year-old child, already affected by 21-hydroxylase deficiency (salt-wasting CAH) diagnosed at 18 days of age, who was referred to our clinic because of typical symptoms of diabetes despite nondiagnostic fasting blood glucose values. Further analysis revealed elevated glycated hemoglobin (HbA1c), low C-peptide, and specific autoantibodies suggesting the diagnosis of T1DM. Although he only started with rapid-acting insulin analogue before meals, he presented spontaneous episodes of hypoglycemia just before the morning hydrocortisone dose, due to an underdosed glucocorticoid intake. Based on continuous glycemic monitoring (CGM), his morning dose was increased and given earlier; then we decided to apply an advanced hybrid closed-loop insulin pump to maintain glycemic time in range above 70%. Fasting glucose in CAH patients can be lower due to underdosed glucocorticoid replacement therapy. HbA1c and CGM can help recognize T1DM onset and evaluate the correct dosage of corticosteroid therapy in CAH patients. New studies are needed to understand the therapeutic approach for a more specific treatment in case of coexistence of these diseases.

Phosphodiesterase type 5 inhibitor tadalafil reduces prostatic fibrosis via MiR-3126-3p/FGF9 axis in benign prostatic hyperplasia.

Myofibroblast buildup and prostatic fibrosis play a crucial role in the development of benign prostatic hyperplasia (BPH). Treatments specifically targeting myofibroblasts could be a promising approach for treating BPH. Tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor, holds the potential to intervene in this biological process. This study employs prostatic stromal fibroblasts to induce myofibroblast differentiation through TGFß1 stimulation. As a result, tadalafil significantly inhibited prostatic stromal fibroblast proliferation and fibrosis process, compared to the control group. Furthermore, our transcriptome sequencing results revealed that tadalafil inhibited FGF9 secretion and simultaneously improved miR-3126-3p expression via TGFß1 suppression. Overall, TGFß1 can trigger pro-fibrotic signaling through miR-3126-3p in the prostatic stroma, and the use of tadalafil can inhibit this process.

Real-world experience with the new pulsed solid-state Thulium: YAG laser (Thulio) for endoscopic enucleation of the prostate.

PURPOSE: The solid-state Thulium laser (Tm: YAG) is a novel alternative to the widely used Holmium laser for endoscopic enucleation of the prostate (EEP) due to its relatively high peak power. The aim of this study was to examine the efficacy and safety of a new pulsed Tm: YAG laser in its first application in humans. METHODS: Data were retrospectively collected for the first 103 patients who underwent EEP with a new pulsed solid-state Tm: YAG laser (Thulio®, Dornier MedTech Systems GmbH, Weßling, Germany). Peri- and postoperative data were assessed. Procedure-specific complications were graded using Clavien-Dindo Classifications (CDC). Patients were interviewed 15 months after the surgery to evaluate functional and long-term outcomes. Statistical analysis was performed with Statistical Package for the Social Sciences (SPSS®). RESULTS: The mean preoperative prostate volume was 105.6 ± 55.0 ml. Median enucleation speed was 4.1 g per minute (range 1.1-9.7). Short-term postoperative complications occurred in 21 patients (20.4%), but no high-grade complications (CDC ≥ IV) were observed. Five patients suffered gross haematuria and required reintervention (CDC IIIb; 4.9%). After 15 months, 76 patients (73.8%) participated in the follow-up interview, where seven patients (9.2%) reported complications, including two reinterventions for urethral strictures (CDC IIIb; 2.6%). Most patients reported an improvement in continence (54.0%) and urine stream (93.4%), but no difference in erectile function (81.6%). No persistent dysuria was reported. Patient satisfaction with the surgery results was very high (96.1%). CONCLUSION: Endoscopic enucleation of the prostate with the new pulsed solid-state Tm: YAG laser is a safe and effective option for surgical BPH treatment. TRIAL REGISTRATION: German Clinical Trials Register number: DRKS00031676. Registration date: 10 May 2023, retrospectively registered.

An altered uterine microbiota with endometrial hyperplasia.

BACKGROUND: Endometrial hyperplasia (EH) is a precursor to endometrial cancer, and the role of the microbiome in its development is unclear. RESULTS: The present study investigated the uterine microbiome in patients with benign uterine conditions and endometrial hyperplasia. A significant structural shift in the uterine microbiome of patients with endometrial hyperplasia compared to those with benign conditions was found. Delftia, Serratia and Stenotrophomonas were significantly enriched in endometrial hyperplasia samples and associated with the presence of endometrial hyperplasia. CONCLUSIONS: The novel finding suggested that increased abundance of Delftia, Serratia and Stenotrophomonas is associated with the presence of endometrial hyperplasia. Further investigation is needed to determine the value of these microbes as biomarkers for endometrial hyperplasia.

When Diagnosis Takes a Turn: A Case Series on Testicular Adrenal Rest Tumor/Leydig Cell Tumor.

Testicular adrenal rest tumor (TART) is a known complication of congenital adrenal hyperplasia (CAH) that simulates testicular germ cell tumors to the extent that they can pose a diagnostic challenge to treating physicians. In this case series, we have presented four patients with different clinical scenarios but all of them presented with a common symptom of bilateral testicular masses. Their clinical histories were strongly suggestive of CAH. Most of them were treated initially as cases of germ cell tumor (Leydig) as their clinical features were overlapping, posing a diagnostic challenge. The histopathological features of CAH and Leydig cell tumors overlap considerably. Diagnosis of CAH must always be kept in mind as a differential diagnosis in patients presenting with bilateral testicular swellings. Timely diagnosis of TARTs and CAH can help preserve testicular functions. Careful histopathological analysis can add to the clinical features of CAH and Leydig tumors to correctly diagnose these patients. Here, we discuss this diagnostic challenge in our four patients.

Transperineal laser ablation (TPLA) of the prostate for benign prostatic obstruction: the first 100 patients cohort of a prospective, single-center study.

PURPOSE: Transperineal laser ablation (TPLA) is a new minimally-invasive surgical treatment for patients with benign prostatic obstruction (BPO). We report the perioperative and mid-term functional results of the first 100 consecutively patients undergoing TPLA at our institution. METHODS: Clinical data from consecutive patients undergoing TPLA at our institution from April 2021 to July 2023 were prospectively collected. Primary endpoints were the postoperative changes in IPSS, QoL and MSHQ 3-item questionnaires and in Qmax and post-void residual volume (PVR). RESULTS: Overall, 100 consecutive patients underwent the procedure. Median age and prostate volume were 66 (IQR 60-75) years and 50 (IQR 40-70) ml, respectively. In the cohort, 14 (14%) patients had an indwelling catheter and 81 (81%) were under oral BPO therapy at the time of TPLA. Baseline median Qmax (ml/s) and PVR (ml) were 9.1 (IQR 6.9-12) and 90 (IQR 50-150), respectively, while median IPSS and QoL were 18 (IQR 15-23) and 4 (IQR 3-4). At all the follow-up timepoints, the evaluated outcomes on both symptoms and functional parameters showed a statistically significant improvement (p < 0.001). Antegrade ejaculation was preserved in all sexually active patients. No postoperative Clavien-Dindo > 2 complications were recorded. CONCLUSIONS: TPLA represents a safe option for selected well-informed patients swith LUTS due to BPO. Our prospective study confirms the feasibility and favorable perioperative and functional outcomes in a real-world cohort with heterogenous prostate volumes and patient characteristics.

A novel variant of the STAR gene: nonclassical presentation from Turkey.

OBJECTIVES: Lipoid congenital adrenal hyperplasia (LCAH) is a rare autosomal recessive disease caused by mutations in the steroidogenic acute regulatory protein (STAR) gene, expressed in the adrenal and gonadal tissues. In classical LCAH, individuals with 46, XY chromosomes present with a female appearance of the external genitalia due to insufficient androgen production. In the non-classical form, a milder phenotype is observed with male external genitalia. Here, we present a non-classical LCAH diagnosis with a newly identified c.266T>A (p.Ile89Asn) likely pathogenic homozygous variant in a 46, XY infant. CASE PRESENTATION: A three-month-and-thirteen-day-old male proband presented with clinical features of cortisol and mineralocorticoid deficiencies. The manifestation of salt-wasting syndrome occurred relatively late, and although the external genitalia appeared male, there was a mild virilization defect. The combination of mild impairment in androgen production and severe salt-wasting syndrome is an intriguing finding in our patient. Peripheral blood samples were obtained from the patient and his family. The newly identified variant, determined by next-generation sequencing analysis, was confirmed by segregation analysis showing carrier status in both parents. CONCLUSIONS: We aim to contribute to the literature by elucidating molecular mechanisms by presenting an atypical presentation and a newly identified variant.

A gel plaster in the form of nipple cover: A comfortable and safe transdermal delivery method for mammary hyperplasia.

Hyperplasia of mammary glands (HMG) is considered a precancerous condition with a risk of malignant transformation, highlighting the necessity of proactive treatment in the early stages. Transdermal drug delivery offers significant advantages such as painlessness, absence of first-pass effect, and good patient compliance. However, the unique structure of the breast requires transdermal formulations for treating mammary hyperplasia to exhibit higher levels of safety and comfort. We have formulated an ancient topical formula called 'Muxiang Bing,' comprising traditional Chinese medicines Aucklandiae Radix (AR) and Rehmanniae Radix (RR), for the treatment of HMG. This formula has been transformed into a gel paster in the form of nipple cover for trans-nipple-areola delivery. In our investigations, we observed that the optimal formulation of the Muxiang gel plaster demonstrated enhanced permeation facilitated by AR's effect on RR. Furthermore, pre-treatment with the Muxiang gel plaster improved mammary tissue morphology, hormone levels, oxidative stress, aberrant cell proliferation, and damage in rat models, thus preventing and ameliorating mammary hyperplasia. The Muxiang gel plaster exhibited low skin irritability in rats, and long-term use did not cause harm to their internal organs or blood cells, indicating its safety and efficacy.

Revisiting Pulmonary Sclerosing Pneumocytoma.

Pulmonary sclerosing pneumocytoma (PSP) is a quite rare tumor outside Eastern countries. This rarity, together with a wide histological appearance, makes its correct identification a diagnostic challenge for pathologists under the microscope. Historically, PSP was considered a vascular-derived neoplasm (sclerosing hemangioma), but its immunohistochemical profile clearly supports its epithelial origin. No specific molecular fingerprint has been detected so far. This short narrative revisits the clinical, histological, immunohistochemical, and molecular aspects of this tumor, paying special attention to some controversial points still not well clarified, i.e., clinical aggressiveness and metastatic spread, multifocality, the supposed development of sarcomatoid change in a subset of cases, and tumor associations with lung adenocarcinoma and/or well-differentiated neuroendocrine hyperplasia/tumors. The specific diagnostic difficulties on fine-needle aspiration cytology/biopsy and perioperative frozen sections are also highlighted. Finally, a teaching case of tumor concurrence of lung adenocarcinoma, neuroendocrine lesions, and PSP, paradigmatic of tumor association in this context, is also presented.

Post-condylectomy orthodontic treatment for a severe asymmetrical open bite in a condylar hyperplasia patient.

A satisfactory treatment of an 18-year-old lady was reported with right combination-type condylar hyperplasia (CH) in active phase. The chin severely deviated to the left, with the right gonial angle locating at a lower level. Intraorally, the lower centre line shifted to the left, the scale of which reached the width of one lower incisor. The right molar relation was mesial. Right maxillary second molar over-erupted without contact to lower teeth. There had been 2.5-mm anterior open bite (AOB) before surgery (T1) due to the tongue-spitting habit. After judging the benefits and disadvantages of all treatment alternatives, the decision was made to perform a right condylectomy and post-surgery orthodontics. Before orthodontics (T2) when the chin was positioned centred, an asymmetrical open bite occurred, caused by pre-contact between the right maxillary and mandibular second molars. Meanwhile, the AOB at T2 became 11.5mm. Orthodontic-related treatment included four premolars extraction and intrusion of bilateral maxillary molars using four miniscrews. Finally, this treatment achieved a clinically centred chin with two gonial angles at the same level. Post-condylectomy, the large AOB was resolved, together with a bilateral neutral molar relationship and alignment of the incisor midlines. Besides, the resected right condyle was covered by a continuous cortex bone and returned to the glenoid fossa. In sum, a high-challenging combined-type CH case was accomplished with impressive improvement in facial and occlusal symmetry, thanks to condylectomy and post-surgery miniscrew-assisted orthodontics.

Holmium laser enucleation of the prostate (HoLEP) in short-circuit outpatient care: Is prostatic volume a limiting factor?

INTRODUCTION AND OBJECTIVES: Our goals were to study prostatic volume as a limiting factor after HoLEP surgery with short-circuit outpatient care (4 h) and to define other factors that affect the success of the proposed circuit. MATERIALS AND METHODS: An observational analysis and review was performed using a prospective database. Preoperative, intraoperative, and postoperative variables were included for patients who were scheduled for short-circuit outpatient care (SCOC) and who underwent HoLEP between 2020 and 2023. We defined SCOC as a postoperative hospital stay of 4 h. Subjects who required more than 4 h in hospital were categorized as conventional hospital admission (CHA). A descriptive populational study was conducted, expressing the mean using a 95% confidence interval and percentages for the continuous variables. In order to analyze them, we used the Student's t-test for the continuous variables and the chi-squared test for the categorical variables. RESULTS: Sixty-eight patients were included, 54 of which completed SCOC, which represented a success ratio of 79.5%. The mean age and prostatic volume of the whole cohort were 68.9 (±6.8) years and 79.5 (±29.1) mL, respectively. We found no significant differences in age, prostatic volume, antiplatelet drug use, indwelling bladder catheter, or applied energy among the subjects who completed SCOC and those who required CHA. No patient was presented with a complication of Grade 3 (or higher) in the modified Clavien-Dindo classification. At the six-month follow-up, no differences were observed in the uroflowmetry or International Prostate Symptoms Score variables. CONCLUSIONS: Prostatic volume does not seem to be a limiting factor after undergoing HoLEP with short-circuit outpatient care.

[Bilateral hyperplasia of the coronoid process in an adolescent patient. case report]. / Hiperplasia bilateral de la apófisis coronoides en paciente adolescente. reporte de caso.

Hyperplasia of the coronoid process is a rare alteration that is characterized by the exaggerated and progressive development of said process over periods of months or years, both in height and volume, which finally causes mandibular hypomobility. It is important to highlight the importance of imaging for the correct diagnosis and treatment of said entity, taking into consideration the great variety of differential diagnoses that can occur. In this sense, conventional radiographs constitute a basic and indispensable tool for approaching the diagnosis. However, it is actually the CT scan that offers the greatest precision. The case of a 14-year-old male patient is presented, with no contributing medical history, who was referred for presenting progressive opening limitation since childhood, for which, after clinical and imaging evaluation, he was treated with total bilateral coronoidectomy, postoperative follow-up was performed. for a year in which recurrence of said entity could be observed. This case demonstrates the importance of correct diagnosis, as well as postoperative control and the rehabilitation scheme carried out by the patient.
