Psammomatoid ossifying fibroma in the frontal sinus: An intriguing clinical encounter-A detailed case report.

BACKGROUND: Psammomatoid ossifying fibroma (POF) is a rare craniofacial neoplasm, primarily affecting the maxillofacial region, and typically observed in adolescents and young adults. This case report presents a unique occurrence of POF in a 50-year-old male, defying the conventional age range and exhibiting an unusual anatomical location within the frontal sinus. CASE: A 50-year-old male with a prior history of cecal adenocarcinoma and colectomy presented with left eye proptosis and new-onset headaches. Imaging revealed a well-defined calcified mass in the left frontal sinus, leading to a diagnosis of POF. Open surgical resection was performed to remove the tumor, and histopathological evaluation confirmed its diagnosis as psammomatoid ossifying fibroma. The patient exhibited no postoperative complications or signs of recurrence. CONCLUSION: This case underscores the diverse clinical presentations and diagnostic challenges associated with POF, emphasizing the importance of accurate diagnosis and multidisciplinary collaboration. Further research is needed to explore the genetic underpinnings and optimal management strategies for this intriguing condition.

Endometrial cancer arising from adenomyosis with unusual manifestation: A case report.

Endometrial Carcinoma Arising from Adenomyosis (EC-AIA) is an unusual condition, primarily occurring in postmenopausal women. We present a rare case of a 34-year-old woman with EC-AIA, highlighting the diagnostic challenges in distinguishing this malignancy from adenomyosis preoperatively. Conventional imaging methods exhibited limitations, necessitating post-surgery confirmation through comprehensive examinations. The case emphasizes the need for a multidisciplinary approach for accurate diagnosis and timely management in such uncommon gynecological conditions.

Extraskeletal mesenchymal chondrosarcoma arising from soft tissues: A rare case report.

BACKGROUND: Chondrosarcomas are an exceedingly rare form of cancer, impacting only a few individuals per million. Among chondrosarcomas, a small fraction belongs to the mesenchymal sub-type. Furthermore, only one-third of mesenchymal chondrosarcomas manifest in extraskeletal locations. CASE: A 38-year-old woman was referred by a midwife after experiencing pain in the right upper quadrant of her right breast for 2 months. The mass had been palpable for 1 week before the initial assessment. According to radiological evaluations, the tumor is outside breast tissue and not connected to the bones. Hence, a biopsy of the mass is done. The biphasic morphology of the tumor during pathological evaluation, in addition to immunohistochemistry testing, confirms the diagnosis of extraskeletal mesenchymal chondrosarcoma (EMCS). Finally, the mass was surgically removed, and 6 months of chemotherapy were administered to the patient. CONCLUSION: Given the tumor's rarity and the lack of established guidelines, diagnosing EMCS can be challenging and prone to errors. As such, meticulous sampling, along with precise pathological and imaging investigations, is imperative to accurately establish the diagnosis of these tumors.

Using a mobile application for psychiatry training in medical students: a quasi-experimental study.

OBJECTIVE: Microlearning and gamification through mobile technology can significantly enhance knowledge acquisition and satisfaction. Roozbehyar application, was designed using microlearning and gamification approaches for psychiatry clerkship training. METHOD: This quasi-experimental study was conducted in Roozbeh Hospital, in 2021. The intervention group was assigned to the Roozbehyar during a 4-week course. Knowledge and satisfaction were assessed after 4 weeks. RESULTS: We recruited 27 (F/M: 19/8) and 35 students (F/M: 22/13) in the intervention and control groups, respectively. Learning through Roozbehyar was associated with higher scores in the final written exam (p value: 0.031). No difference was seen in the final global assessment scores. The satisfaction scores of the students regarding the content and learners' aspect of the application were above average, yet scores in structural and support aspects were below average. CONCLUSIONS: We highlighted the effect of a microlearning mobile application in increasing knowledge and satisfaction in psychiatry training in medical students.

Investigation of two general venous thromboembolism risk-stratification models in predicting venous thromboembolic events in TB patients.

Background: Tuberculosis (TB) remains an infectious disease with a high prevalence worldwide and represents a major public health concern. It is known that TB causes a hyper-coagulable state due to its infective nature. Thus, patients are prone to higher incidence rates of venous thromboembolism (VTE) in comparison with the general population. Although there are many risk assessment models (RAMs) that estimate the risk of VTE incidence in the general population, none have been proven to show significant prognostic value in early and accurate VTE prediction among TB patients. This study aims to investigate the accuracy of general RAMs in prediction of VTE incidence in the population of TB-positive patients. Methods: The following survey is a retrospective study among patients afflicted with TB, in whom VTE had occurred either during or at the onset of admission. A total number of 865 smear-positive TB cases were recorded in hospital in a 7-year timespan, among which a total sum of 37 patients (67.6% males, age: 56.19 ± 20 years) experienced at least one episode of thromboembolic incidence. We nominated Padua and Geneva RAMs and calculated the scores with regard to their inpatient hospital records. Results: Of 865 adult hospitalized smear-positive TB patients, 37 patients happened to develop VTE in the course of infection, after excluding the unacceptable data. The incidence of VTE was calculated at 4.27%. Of all VTEs, 73% turned out to be deep venous thromboembolism (DVT), 18.9% were pulmonary thromboembolism (PTE), and 8.1% of patients developed both DVT and PTE during the course of disease. Among all cases, 32.4% revealed Geneva score equivalent or >3. It conveys the meaning that these patients were at greater risk for VTE development and were indicated to receive prophylactic medication. Similarly, Padua model was capable of predicting 29.7% cases scoring >4, which is alarming for elevated VTE probability. 21.6% of TB patients, who had developed VTE during the course of their disease eventually passed away. Conclusion: Our statistics show minimal positive predictive value for Padua and Geneva RAMs, which are seemingly in sharp contrast with the excellent validation of these models verified by numerous surveys in general population. This fact could be attributable to failing to consider TB, or in general chronic infections, as independent indicators of VTE incidence. These findings indicate the need for revising the presenting RAMs or establishing a separate RAM for VTE prediction in TB patients, resembling the VTE risk assessment model for cancer patients.

"Always Look on the Bright Side of Life!" - Higher Hypomania Scores Are Associated with Higher Mental Toughness, Increased Physical Activity, and Lower Symptoms of Depression and Lower Sleep Complaints.

Background: In the present study, we explored the associations between hypomania, symptoms of depression, sleep complaints, physical activity and mental toughness. The latter construct has gained interest for its association with a broad variety of favorable behavior in both clinical and non-clinical samples. Subjects and Methods: The non-clinical sample consisted of 206 young adults (M = 21.3 years; age range: 18-24 years; 57.3% males). They completed questionnaires covering hypomania, mental toughness, symptoms of depression, physical activity, and sleep quality. Results: Higher hypomania scores were associated with higher mental toughness, increased physical activity, lower symptoms of depression and lower sleep complaints. No gender differences were observed. Higher hypomania scores were predicted by higher scores of mental toughness subscales of control and challenge, and physical activity. Conclusion: The pattern of results suggests that among a non-clinical sample of young adults, self-rated hypomania scores were associated with higher scores on mental toughness and physical activity, along with lower depression and sleep complaints. The pattern of results further suggests that hypomania traits are associated with a broad range of favorable psychological, behavioral and sleep-related traits, at least among a non-clinical sample of young adults.
