Spontaneous Pregnancy after 4D-Hysterosalpingo-Sonography (HyCoSy) in the Same Menstrual Cycle: A Case Report and an Updating Review of the Current Literature regarding the Positive Impact of Tubal Flushing Effect on Fertility.
Infertility is increasing worldwide, as well as in Italy, and fallopian tube pathology represents one of the most impacting causes of infertility for multiple women. Indeed, tubal patency assessment is a crucial step in medical evaluation for women attending an in vitro fertilization (IVF) center. Currently, different methods for tubal investigation are available, such as chromosalpingoscopy, hysterosalpingography (HSG), and hysterosalpingo-contrast sonography (HyCoSy). This diagnostic exam is performed by ultrasonography and an air-water-based contrast agent represented by air-water, or foam solution (HyFoSy). An additional side benefit of these assessment tests is a fertility-enhancing effect, thanks to a positive effect defined as "tubal flushing," which in current literature is more strongly associated with HyFoSy with respect to HyCoSy. In this report, we present a case of a 34-year-old woman presented to our attention at the Reproductive and Physiopathology Unit of Sandro Pertini Hospital, Rome, in 2023, with unexplained infertility for 3.1 years of free sexual intercourse with a partner who did not report sperm abnormalities. Subsequently, in this exam, the woman spontaneously conceived in the same menstrual cycle that the 4D-HyCoSy was performed, without any additional fertility enhancement interventions. In this case report, we also include an updating review of the current literature regarding the insurgence of spontaneous pregnancy after this technique in order to explore the physiopathological and etiopathogenetic mechanisms underlying the achievement of spontaneous pregnancy and to confront our case with other recent works published. According to our clinical experience and the current literature, 4D-HyCoSy is the easiest, safest, and cheapest diagnostic exam for investigating tubal patency, which can lead to medical success in some cases of "unexplained infertility" as the achievement of a spontaneous pregnancy.

INTRODUCTION
To describe a rare case of solitary bone cyst in the vertebral body of the lumbar vertebra in an adult patient. The solitary bone cyst is defined as a cystic lesion with liquid content. Few cases have been described in the vertebral location without preference for the posterior arch or vertebral body. Most have been treated with resection, curettage, and/or grafting. No case described to date has been treated with polymethylmetacrylate (PMMA) injection in the vertebral location. . A 50-year-old male patient was consulted for lumbar pain with no traumatic history and no neurologic deficit. The radiological study showed lumbar arthrodesis with L2-L4 instrumentation due to an L3 fracture twenty years earlier. Computed tomography (CT) scan showed a lytic lesion occupying practically the entire vertebral body of L5, with incomplete septum and sclerotic edge, without cortical rupture. The previous steel instrumentation was removed, to avoid the presence of artifacts when performing the magnetic resonance (MR), and a biopsy of L5 vertebra was performed via transpedicular in the same act. The MR study findings and biopsy were compatible with the simple bone cyst. Finally, a new intervention was performed by filling the lesion with PMMA. Follow-up at 5 years was satisfactory without lumbar pain as well as the radiological study and with a return to previous activity.
CONCLUSIONS
The spinal location of the simple bone cyst is extremely infrequent. Its diagnosis excludes other lesions and is made by imaging studies and biopsy. Treatment can be performed by excision, curettage, or filling with graft or as in this case, with PMMA.

STATEMENT OF THE PROBLEM
Although various kinds of research have been conducted to compare the physical and chemical properties of dentin and enamel in animal and human samples, proving the ability of animal dentin material as a good substitute for human specimens is always a challenge for experimental studies.
PURPOSE
The aim of the present study is to investigate whether the changes in the dentin microhardness of animal samples are similar to those of human samples or not.
MATERIALS AND METHOD
In this study, sixty single-rooted human, bovine, and ovine teeth (n=20 in each group) were decoronated at CEJ. The remaining roots were embedded in acrylic resin and a cross-section cut was made in the middle of the samples in order to achieve dentin disks. All of the 120 samples were randomly assigned to three control (n=20 for each group) and three experimental groups (n=20 for each group). In the experimental groups, calcium hydroxide with a creamy consistency was prepared and the disks were embedded in dishes containing calcium hydroxide. Control groups were embedded in physiological saline. The samples were incubated for seven days at the 37oC and Vickers microhardness test was performed immediately. The average of three yielded values was considered as the final value of microhardness. Data were analyzed using two-way ANOVA, one-way ANOVA, and Tukey's post hoc tests.
RESULTS
In the control group, the human samples showed the highest microhardness value, while the bovine teeth had the lowest microhardness value (< 0.001). In the calcium hydroxide group, the human samples showed the highest microhardness value in comparison to bovine and ovine to teeth. However, no significant difference was observed between the bovine and ovine samples in microhardness value.
CONCLUSION
Based on our research, substituting bovine and ovine samples with human samples in experimental studies is not recommended. Nevertheless, more studies are needed in this regard.

Successful treatment of pediatric patients with high-grade gliomas featuring leptomeningeal metastases by targeting BRAF V600E mutations with dabrafenib plus trametinib: two illustrative cases.
A combination of BRAF and MEK inhibitors is reported to be effective for gliomas with the BRAF V600E mutation; however, its efficacy in gliomas with leptomeningeal metastases (LMM) is still unknown. In this report, we describe two pediatric patients with high-grade glioma featuring the BRAF V600E mutation who were treated with dabrafenib and trametinib for LMM. Both 2 cases underwent craniotomy for primary intracranial lesions and were diagnosed as a high-grade glioma with BRAF V600E mutation; one case was consistent with anaplastic pleomorphic xanthoastorocytoma, the other was epithelioid glioblastoma. They received standard treatment for the lesions but subsequently were found to have new lesions including multiple spinal dissemination. We started administering dabrafenib and trametinib. Within a few days of starting treatment, the symptoms improved dramatically and MRI performed one month after the prescription of the two drugs demonstrated remission of both brain and spinal lesions. This report shows that dabrafenib and trametinib are effective not only for recurrent lesions but also for LMM in pediatric patients.

Dedifferentiated liposarcoma is a rare cancer with a poor prognosis. A 52-year-old man presented with a chief complaint of a mass in his left scrotum. He came with suspected testicular tumor, but all the measured tumor markers were negative. Imaging test showed approximately 2 cm diameter mass accompanied by calcification with some substantial components between the testis and epididymis. Left high testicular resection was performed. The tumor had no continuity between the testis and epididymis, and the spermatic cord transection was negative. Pathological findings showed well differentiated fatty component and a dedifferentiated component around the trabecular bone-like tissue. We observed dedifferentiated dysmorphic cells mixed with fatty droplets of unequal size. Immunostaining led to the diagnosis of dedifferentiated liposarcoma. No additional postoperative therapy was performed. The possibility of dedifferentiated liposarcoma should be kept in mind even if mass is confined to the scrotum and consisted of calcification. In the case of an intrascrotal calcified mass with malignant perspective, radical surgery is highly recommended.

A 61-year-old woman with pathogenic variant had been treated for 20 years and showed dynamic changes in the genomic profile of her metachronous bilateral breast cancer and metastases. She underwent right breast conservation surgery at age 42-Genome 1, lung metastasis and left axillary lymph node metastasis at age 51, partial excision under local anesthesia for left breast cancer at age 53-Genome 2, left axillary lymph node dissection was added 6 month later-Genome 3. Then, olaparib was administered, and subsequently, left mastectomy was performed for the recurrence of left breast cancer at age 59-Genome 4. Genomic profile of the tumor was analyzed at four points (Genome 1-3 were analyzed by in house breast cancer panel, and Genome 4 was analyzed by Foundation One CDx). Two interesting findings emerged from these analyses. First, the genomic profile revealed that the left axillary lymph node metastasis, considered histologically from right breast cancer, was a metastasis from the left breast cancer. The second finding is that as the disease progressed, mutation profile became more diverse. The profile of the left breast cancer removed after olaparib and other treatments showed reversion mutation of and was diagnosed as tumor mutation burden high. Subsequent response to pembrolizumab was favorable.

No standard treatment has been established for gastric neuroendocrine carcinoma (G-NEC). We present the case of a patient with recurrent G-NEC who achieved a complete response (CR) with nivolumab. A woman in her 70 s, with no significant medical or family history of illness, underwent an upper gastrointestinal endoscopy, which revealed a Borrmann type 2 tumor in the gastric antrum. Malignant tumor cells were not detected in the endoscopic biopsy samples; however, a malignant gastric tumor was strongly suspected. Therefore, surgical resection was performed, and the tumor was pathologically diagnosed as a G-NEC with liver metastases. Adjuvant etoposide plus carboplatin was administered for four cycles, but recurrence in the liver was observed 5 months after the completion of adjuvant chemotherapy. Ramucirumab plus paclitaxel and irinotecan were introduced as second and third-line treatments. After these treatments, the mesenteric lymph node metastases expanded. Tumor mutation burden (TMB) was low (five mutations/megabase), and microsatellite instability remained stable. However, programmed death-ligand 1 Combined Positive Score (CPS) was ≥ 5 in the resected sample. Therefore, nivolumab monotherapy was introduced as a fourth-line treatment. The mesenteric lymph node metastases exhibited swelling 3 weeks after the initiation of nivolumab; however, they rapidly shrank, and CR was later achieved. Treatment with nivolumab is currently ongoing for 12 months. This is the first report of nivolumab monotherapy in a patient with G-NEC who showed pseudo-progression. Even in TMB-low and microsatellite stable cases, nivolumab may be a viable option for patients with G-NEC.

A patient who underwent conversion surgery after atezolizumab plus bevacizumab for hepatocellular carcinoma with portal vein thrombosis and perihepatic lymph node metastases achieved a pathological complete response.
Here, we present a patient with hepatocellular carcinoma complicated by tumor thrombosis into the main portal trunk and perihepatic lymph node metastases who was treated with atezolizumab plus bevacizumab. Shrinkage of the main tumor, portal vein thrombosis, and lymph node metastases were achieved; therefore, hepatectomy with lymphadenectomy could be performed. Final pathology indicated a complete pathological response in the main tumor, portal vein thrombosis, and perihepatic lymph nodes. The patient is currently alive with no evidence of recurrence on radiological assessment at 3 months after surgery.

A 72-year-old female was referred to our institution for further evaluation of right renal tumor detected during work-up for macroscopic hematuria in other hospital. CT urography performed at our institution suggested renal pelvic tumor. Voiding cytology was atypical. CT also revealed a small mass in the right mammary gland. Percutaneous needle biopsies were performed on the right mammary gland and renal mass, leading to a pathological diagnosis of UC with plasmacytoid subtype, suggesting metastasis from the renal pelvic UC to the mammary gland. She had a favorable response to four cycles of dose-dense MVAC therapy; therefore, we performed nephroureterectomy. One month after nephroureterectomy, new intraperitoneal metastatic lesions were observed and pembrolizumab therapy was started. After seven doses of pembrolizumab, CT revealed a marked size reduction of intraperitoneal metastases and the mammary metastasis remained small.

Intracranial tuberculomas diagnosed with Xpert MTB/RIF Ultra assay of formalin-fixed paraffin-embedded brain tissues and treated with an optimized antituberculosis regimen: A case report.
Diagnosis of intracranial tuberculoma remains a challenge due to its rarity, non-specific clinical presentation, and radiological findings. Herein, we describe a case of intracranial tuberculomas in a male diabetic patient who presented headache and vomiting on admission. Neuroimaging findings indicated multiple ring contrast-enhanced lesions with extensive perilesional edema. However, a cerebrospinal fluid (CSF) examination was normal. When a biopsy of brain lesions was performed, pathological characteristics of tuberculosis were absent and acid-fast staining was negative. A tuberculosis diagnosis was subsequently obtained from an Xpert MTB/RIF Ultra assay of formalin-fixed paraffin-embedded brain tissue. The patient was treated with an optimized anti-tuberculosis regimen which included high-dose intravenous administration of rifampicin and isoniazid, and oral administration of linezolid. The patient recovered well and exhibited marked clinical improvement. This case report demonstrates that when CSF analysis does not indicate the presence of intracranial tuberculomas, analysis of formalin-fixed paraffin-embedded brain tissue specimens with the Xpert MTB/RIF Ultra assay may be able to confirm a diagnosis. Furthermore, a high dose of rifampicin and isoniazid plus linezolid may improve patient outcome.
