DEMOGRAPHIC PROFILE, SUBSTANCE USE TRENDS AND ASSOCIATED PSYCHOTIC DISORDERS AMONG VETERANS WITH MENTAL HEALTH CONDITIONS: A RETROSPECTIVE COHORT STUDY OF US VETERANS Background: Amphetamine and other substances induced psychotic disorder and associated suicidal risk among hospitalized US veterans is not clear. Aims: To understand the demographic profile, substance use trends, psychotic disorders and suicide attempts in veterans hospitalized with acute Mental Health Conditions (MHC). Methods: Veterans Affairs Informatics and Computing Infrastructure Database (ICD) and codes were used to identify veterans hospitalized with MHC diagnosis between 1999 and 2022. Laboratory records used to determine types of substances used hospitalization frequency, all-cause mortality, suicide attempts and suicide outcomes. SAS was used for statistical analysis. Results: Among veterans with MHC, psychosis, manic-bipolar and PTSD were common diagnosis. Psychosis was comparatively less among males above 50 years of age, but prevalent among Hispanics. In general, substances use was significantly higher, and amphetamines were most used, followed by cannabis codeine, morphine, cocaine, barbiturates, fentanyl, and PCP among veterans with MHC. Amphetamine induced psychotic disorder persisted in 22.28% and other substance induced psychotic disorder persisted in 77.72% of veterans hospitalized with MHC. Psychosis was associated with higher rates of hospitalization, suicide attempts, and suicide death. Conclusions: Among US Veterans with MHC, amphetamine was most used substance associated with higher rates of psychotic disorders, hospitalization, suicide attempts, and death.

Background: Platelet aggregation studies using conventional light transmission aggregometry (LTA) have several disadvantages and require strict pre-analytical measures for reliable results.We aimed to examine the utility of flow cytometric platelet aggregation (FCA) assay in detecting platelet function defects (PFDs) in patients with a history of bleeding symptoms. Methods: Sixty-four participants (24 patients and 40 healthy controls) were included in this study.LTA and FCA assay were performed simultaneously in patients and healthy controls. In the FCA assay, two portions of platelets from the same individual were labeled separately with CD31-FITC and CD31-PE. After mixing and stimulation with agonists, the double-colored platelet aggregates were visualized using a flow cytometer. The results generated using the two techniques were compared and correlated. Results: The patients’ median age was 17 years (range, 3‒72 yr) with a male-to-female ratio of 1:1.7. There was substantial agreement between LTA and FCA assay in detecting a PFD (κ=0.792). Four patients showing a Glanzmann thrombasthenia-like pattern on LTA exhibited an abnormal FCA. A functional defect in collagen binding was detected on the FCA assay conducted in two immune thrombocytopenic patients with severe bleeding. Conclusion FCA assay can be used to identify functional defects in platelets, with potential applications in thrombocytopenic individuals. It also facilitates the diagnosis of inherited bleeding disorders with platelet defects.

OBJECTIVES: This study examined the effects of plasma-rich growth factors (PRGF) on accelerating bone regeneration/repair in fresh extraction sockets, and determined the quality and quantity of bone by assessing the bone density using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: Twenty patients, who had undergone bilateral extractions, were included in this study. In one extraction socket, PRGF was used and covered with an autologous fibrin plug. Nothing was used in the opposite side extraction socket. Thirteen weeks post extraction, the level of bone regeneration was evaluated on both sides with CBCT. RESULTS: At the end of the study, the mean bone density according to the Hounsfield units (HU) in the control group and PRGF group was 500.05 HU (type III bone type) and 647.95 HU (type II bone type), respectively. CONCLUSION This study recommends the use of PRGF in post extraction sites to accelerate the rate of bone regeneration and improve the quality of regenerated bone. The technique to process PRGF was simple compared to previously mentioned techniques used for platelet-rich plasma (PRP) preparation. PRP preparation requires a two-cycle centrifugation procedure, leading to a longer processing time.

Von Hippel-Lindau (VHL) syndrome is a rare neoplastic disorder characterized by central nervous system (CNS) and visceral tumors. We here present 68Ga-labelled [1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid]-1-Nal3-Octreotide positron emission tomography computed tomography findings in a 52 year old female with VHL syndrome, demonstrating both CNS and visceral tumors.

Acquired bilateral pulmonary artery stenosis in adults due to lung malignancy is infrequently reported. We describe an adult male who presented to us with chief complaints of dyspnea on exertion and one episode of hemoptysis. Two dimensional transthoracic echocardiography with color Doppler showed presence of an extra cardiac mass causing severe extrinsic compression of both the right and left pulmonary artery leading to high pressure severe tricuspid regurgitation and extension of the mass into the left atrium. Three dimensional transthoracic echocardiography clearly delineated the anatomy of the left atrial mass and its surrounding anatomical relationship. The diagnosis of non small cell lung carcinoma was confirmed by multidetector computed tomography (MDCT) and with MDCT guided biopsy with histopathology. Patient succumbed one month later due to an episode of massive hemoptysis.

Endovascular management of intraparenchymal renal artery pseudoaneurysms is a reasonable and effective therapeutic technique. Endovascular management preserves the maximum amount of renal tissue and reduces the potential risk of nephrectomy. We present the case of an angiocatheter that became stuck in the renal artery following the injection of cyanoacrylate glue for angioembolization of an intrarenal pseudoaneurysm.

PURPOSE: To review our experience with the management of fragmented and retained pigtail percutaneous nephrostomy (PCN) tubes and to explore the reasons for the fragmentation. MATERIALS AND METHODS: We retrospectively reviewed our institute database from January 2006 to December 2011 for patients who had undergone retrieval of fragmented PCN tubes. We assessed the preoperative factors, operative technique, and post-operative outcomes. RESULTS: A total of seven patients (4 males and 3 females) had been diagnosed with fragmented PCN tubes. The mean age of the patients was 41.5 years. Of the seven patients, five required antegrade instrumentation by way of a percutaneous tract to remove the foreign body, mostly along with stone retrieval. One patient underwent ureterorenoscopy and pneumolithotripsy for a ureteric stone along with ureteroscopic removal of the PCN fragment. Another patient underwent nephrectomy of the kidney containing the PCN fragment because it had become nonfunctioning. All patients were free of stones and symptoms on follow-up. CONCLUSIONS: A prolonged waiting period for definitive surgery, urinary infection, and associated stone disease are significant factors causing fragmentation of PCN tubes. Proper insertion techniques, regular timed changes of the PCN tube, appropriate care of the PCN tube, and early surgery for underlying stone disease are required to avoid this complication. Patients with retained PCN tubes can be managed effectively with antegrade or retrograde endoscopic techniques while definitive management of the primary pathology is carried out, without any additional morbidity.
