A Rare Case of a Morel-Lavallée Lesion Complicated by Pseudomonas aeruginosa Infection: Diagnostic Challenges and Therapeutic Considerations.

Morel-Lavallée lesions are uncommon soft tissue injuries resulting from trauma, characterized by the separation of subcutaneous tissue from the underlying fascia. Soft tissue infections with Pseudomonas aeruginosa are rare and most typically associated with hospital-acquired infections and burn wounds. This case report is regarding a 57-year-old man following a motorcycle accident who presented with a unique occurrence of an MLL complicated by P. aeruginosa infection. The patient underwent extensive treatment over the course of months, which may have been prevented with a better understanding of the injury. This case is noteworthy due to the infrequency of the injury, the pathogen, and concomitant occurrence, presenting a diagnostic and therapeutic challenge. We describe the patient's clinical presentation, hospital course, diagnostic workup, and management to inform future care and recognition of similar patients.

A Rare Case of Herpes Simplex Virus and Cytomegalovirus Dual Infection Inducing Unremitting Ulcerative Colitis.

Ulcerative colitis (UC) is a subtype of inflammatory bowel disease that results in inflammation and ulceration in the lining of the large intestine. Patients with UC are frequently prescribed immunosuppressive medications to treat their symptoms, resulting in an increased risk of reactivation of many latent viruses, including herpes simplex virus (HSV) and cytomegalovirus (CMV). However, it is rare for a patient to present with simultaneous reactivation of both viruses. Here, we document the presentation, hospital course, and clinical findings of a UC patient with HSV and CMV dual infection. We also describe treatment strategies and prophylactic measures for managing a dual infection. This is seen through initiating valganciclovir in the outpatient setting following the diagnosis.

Zinc Ortho Methyl Carbonodithioate Improved Pre and Post-Synapse Memory Impairment via SIRT1/p-JNK Pathway against Scopolamine in Adult Mice.

Alzheimer's disease (AD) is globally recognized as a prominent cause of dementia for which efficient treatment is still lacking. New candidate compounds that are biologically potent are regularly tested. We, therefore, hypothesized to study the neuroprotective potential of Zinc Ortho Methyl Carbonodithioate (thereafter called ZOMEC) against Scopolamine (SCOP) induced Alzheimer's disease (AD) model using adult albino mice. We post-administered ZOMEC (30 mg/Kg) into two group of mice for three weeks on daily basis that received either 0.9% saline or SCOP (1 mg/Kg) for initial two weeks. The other two groups of mice received 0.9% saline and SCOP (1 mg/Kg) respectively. After memory related behavioral analysis the brain homogenates were evaluated for the antioxidant potential of ZOMEC and multiple protein markers were examined through western blotting. Our results provide enough evidences that ZOMEC decrease oxidative stress by increasing catalase (CAT) and glutathione S transferase (GST) and decreasing the lipid peroxidation (LPO). The SIRT1 and pre and post synaptic marker proteins, synaptophysin (SYP) as well as post synaptic density protein (PSD-95) expression were also enhanced upon ZOMEC treatment. Furthermore, memory impairment was rescued and ZOMEC appreciably abrogated the Aß accumulation, BACE1 expression C and the p-JNK pathway. The inflammatory protein markers, NF-kß and IL-1ß in ZOMEC treated mice were also comparable with control group. The predicted interaction of ZOMEC with SIRT1 was further confirmed by molecular docking. These findings thus provide initial reports on efficacy of ZOMEC in SCOP induced AD model.

Operative challenges of intramedullary nailing for subtrochanteric blastic pathological femur fracture: a case report.

Prostate adenocarcinoma metastasizes to bone and forms fragile blastic lesions, which can present as dense obstacles intraoperatively. There are limited reports on the challenges surgeons face when operating through these lesions. A 60-year-old male with a pathologic subtrochanteric femur fracture in the presence of blastic lesions was successfully treated with intramedullary (IM) fixation. Pathologic fractures from blastic bone lesions are expected to increase in prevalence as survivability improves for metastatic prostate cancer. Orthopedic surgeons, when performing IM fixation for these fractures, should be prepared to utilize accessory equipment and should adopt creative techniques for reduction and fixation.

Malignant Epiretinal Membrane After Proton Beam Radiation of Ciliary Body Melanoma.

Purpose: To report the development of malignant epiretinal membrane after radiation of ciliary body melanoma. Case Report: A 65-year-old woman was referred for evaluation of a ciliary body tumor in her right eye. On examination, a pigmented ciliary body tumor, displacing the iris anteriorly, was visible superotemporally and ultrasound biomicroscopy revealed a large solid ciliary body tumor. She was diagnosed with ciliary body melanoma and treated with proton beam radiation. Over the following 29 months, the treated tumor regressed but optical coherence tomography (OCT) showed the development of a dense epiretinal membrane. Enucleation was performed and histopathological examination showed viable melanoma cells in the vitreous cavity with sheet-like growth of viable spindle melanoma cells on the epiretinal surface. Conclusion: The development of a pigmented epiretinal membrane in eyes with uveal melanoma should raise the possibility of a malignant epiretinal membrane.

ZOMEC via the p-Akt/Nrf2 Pathway Restored PTZ-Induced Oxidative Stress-Mediated Memory Dysfunction in Mouse Model.

A new mechanistic approach to overcome the neurodegenerative disorders caused by oxidative stress in Alzheimer's disease (AD) is highly stressed in this article. Thus, a newly formulated drug (zinc ortho-methyl carbonodithioate (ZOMEC)) was investigated for five weeks on seven-week-old BALB/c male mice. ZOMEC 30 mg/kg was postadministered intraperitoneally during the third week of pentylenetetrazole (PTZ) injection. The brain homogenates of the mice were evaluated for their antioxidant potential for ZOMEC. The results including catalase (CAT), glutathione S transferase (GST), and lipid peroxidation (LPO) demonstrated that ZOMEC significantly reverted the oxidative stress stimulated by PTZ in the mouse brain. ZOMEC upregulated p-Akt/Nrf-2 pathways (also supported by molecular docking methods) to revoke PTZ-induced apoptotic protein markers. ZOMEC reversed PTZ-induced neuronal synapse deficits, improved oxidative stress-aided memory impairment, and inhibited the amyloidogenic pathway in mouse brains. The results suggested the potential of ZOMEC as a new, safe, and neurotherapeutic agent to cure neurodegenerative disorders by decreasing AD-like neuropathology in the animal PTZ model.

Black-white Differences in Left Ventricular Hypertrophy Rates Among Young Adults with Ischemic Stroke.

OBJECTIVES: Few studies have addressed Black-White differences in left ventricular hypertrophy (LVH) in young stroke patients without a history of hypertension. METHODS: A case-only cross-sectional analysis performed in 2019 of data from the Stroke Prevention in Young Adults Study, a population-based case-control study of ischemic stroke patients ages 15-49. The main outcomes were hypertension indicators at the time of stroke hospitalization: self-reported history of hypertension, LVH by echocardiography (Echo-LVH) and LVH by electrocardiogram (ECG-LVH). The prevalence of Echo-LVH was further determined in those with and without a history of hypertension. Adjusted odds ratios and 95% confidence intervals comparing blacks and whites were calculated by logistic regression. RESULTS: The study population included 1028 early-onset ischemic stroke patients, 48% Black cases, 54% men, median age 43 years (interquartile range, 38-46 years). Overall, the prevalence of hypertension history, Echo-LVH and ECG-LVH were 41.3%, 34.1% and 17.5%, respectively. Each of the hypertension indicators were more frequent in men than in women and in Black cases than in White cases. Black patients without a history of hypertension had higher rates of Echo-LVH than their white counterparts, 40.3% vs 27.7% (age and obesity adjusted OR 1.8; 95% CI 1.02-3.4) among men and 20.9% vs 7.6% (adjusted OR 2.7; 95% CI 1.2-6.2) among women. CONCLUSIONS: LVH was common in young patients with ischemic stroke, regardless of self-reported history of hypertension. These findings emphasize the need for earlier screening and more effective treatment of hypertension in young adults, particularly in the Black population.

Proton-pump-inhibitor use associated with lower short-term rebleeding and mortality in patients receiving esophageal variceal band ligation: a retrospective cohort study.

BACKGROUND: The impact of proton-pump inhibitor (PPI) therapy on subsequent hemorrhage and mortality after variceal hemorrhage is unclear. AIM: Evaluate the associations of PPI use with upper gastrointestinal bleeding (UGIB) and death within 30 days of undergoing esophageal variceal band ligation (EBL) separately in inpatient and outpatient settings. METHODS: Retrospective review of cirrhotic patients with variceal hemorrhage who underwent EBL between 2005 and 2018. Endoscopic findings, PPI use at admission (inpatients only), PPI use at discharge (inpatients and outpatients), and adverse outcomes data (liver transplant, UGIB, transjugular intrahepatic portosystemic shunt, and death within 30 days of discharge or death during hospitalization) were reviewed. RESULTS: A total of 446 patients (164 inpatients, 282 outpatients) were included. The most commonly observed outcomes were death within 30 days of discharge in inpatients (12.8%), UGIB within 30 days of discharge in inpatients (21.3%), and UGIB within 30 days of discharge in outpatients (8.5%). For inpatients, prescription of PPI at discharge was associated with a lower risk of bleeding within 30 days (odds ratio: 0.30, P = 0.025) and death within 30 days (odds ratio = 0.16, P = 0.002). No other significant associations of PPI with death or UGIB were reported. CONCLUSION: Post-EBL PPI therapy is associated with reduced risk of bleeding and death within 30 days after variceal hemorrhage in hospitalized patients.

Laser Myringotomy Versus Ventilation Tubes In Otitis Media With Effusion.

BACKGROUND: Otitis media with effusion (OME) is a leading cause of difficulty in hearing in paediatric population. Otitis media with effusion must be detected and managed early to prevent conductive hearing loss in children. It was aimed to compare results of laser myringotomy and ventilation tube insertion, in terms of hearing improvement and recurrence of Middle ear effusion (MEE). METHODS: This randomized controlled trial was conducted from February 2012 to January 2015. Children of 4- 12 years of age with decreased hearing due to OME were included in the study. These children were investigated with pure tone audiometry (PTA) and tympanometry to confirm conductive hearing loss. Patients were put in 2 groups, group one comprised of patients treated with laser myringotomy and group 2, treated with ventilation tube insertion. The objective was to evaluate and compare results of the two procedures in terms of resolution of middle ear effusion (MEE) and improvement of hearing. The two procedures were also compared in terms of complications like otorrhea, persistence of perforation, hypertrophic scar and thinning of tympanic membrane (TM). RESULTS: Middle ear effusion cleared in 35 out of 68 ears with laser myringotomy (LM) as compared to 52 out of 62 ears with ventilation tubes (VT). The myringotomy was still patent in 21 ears treated with LM while tube was in site in 50 years with VT after 3 months. The hearing level improved with LM by 10-15 dB after first 3 months. CONCLUSIONS: The aim in Otitis media with effusion is ventilation of tympanic cavity. Laser myringotomy can be substitute to ventilation tube insertion (VT). But it remains patent for shorter time and less effective than VT. The ears with refractory or recurrent MEE should have VT insertion.

Laser and incisional myringotomy in otitis media with effusion-a comparative study.

BACKGROUND: Otitis media with effusion (OME) or middle ear effusion (MEE) is a common cause of hearing difficulty in children. MEE must be detected early and managed properly to prevent conductive hearing loss in children. It was aimed to compare results of laser myringotomy and conventional myringotomy in terms of hearing improvement, recurrence of MEE and time to put ventilation tube. METHODS: This randomized control trial was conducted from February 2012 to April 2014. Children of 4 years age or older with MEE were included in the study. These children were investigated with Pure tone audiometry (PTA) and tympanometry to confirm conductive hearing loss. X-Ray nasopharynx lateral view was performed for adenoids. Sixty-six patients were randomly assigned in to 2 groups, (1) treated with laser myringotomy and (2) treated with classical myringotomy. The ears were evaluated for MEE, for presence of perforation and level of hearing. RESULTS: A total of 98 ears in 66 patients underwent intervention. Middle ear effusion cleared in 44 out of 48 ears with laser myringotomy (LM) as compared to34 out of 50 ears with incisional myringotomy. The perforation was still patent in 36 ears treated with LM while it was found closed in all 50 ears with conventional myringotomy after 2 weeks. The hearing level improved with LM by 10-15 dB after first 3 months. CONCLUSION: The aim of management in otitis media with effusion is ventilation of tympanic cavity. Laser myringotomy is a best alternative to conventional one. It also has comparable results with ventilation tubes (VT). The ears with refractory or recurrent MEE should have VT insertion.

Medical versus surgical management of otitis media with effusion in children.

BACKGROUND: Otitis media with effusion (OME) is a leading cause of hearing difficulty in children. OME must be detected early and managed properly to prevent hearing and speech impairment in children. This study was aimed to compare results of medical and surgical treatments in terms of hearing improvement, recurrence of Middle Ear Effusion (MEE), time to offer surgical intervention. METHODS: The study was conducted from June 2008 to December 2011. A performa was used to collect data. Every child having hearing difficulty was examined with pneumatic otoscope for fluid level and tympanic membrane mobility. These children were investigated with pure tone audiometry for level of hearing loss and tympanometry to confirm the middle ear effusion. X-Ray nasopharynx lateral view was taken to see if there were adenoids. All patients were treated conservatively in the first phase. Those not responding to conservative treatment were treated with myringotomy and adenoidectomy with or without ventilation tubes. Patients were followed-up for up to 36 months. RESULTS: Middle ear effusion cleared in 80 (71.5%) out of 112 ears. No improvement was noted in 32 ears for 9 months. Resistant and recurrent cases were managed with adenoidectomy and myringotomy alone or with insertion of ventilation tubes (VT). Recurrence was noted more common with myringotomy alone than with ventilation tubes. Medical treatment failed in 32 ears. MEE recurred in 9 ears. VT was put in 41 ears. The hearing level improved with VT by 10-15 dB after first 3 months. CONCLUSION: All children with OME should be treated conservatively. It is cost effective and relieves MEE in about 70% of patients. The ears with OME that fails to resolve or recur should be managed with myringotomy and VT insertion or adenoidectomy.

Efficacy, safety and tolerability of streptokinase in multiloculated empyema.

BACKGROUND: Empyema thoracis is a common illness with significant morbidity and mortality. Standard treatment of Empyema includes tube drainage and antibiotics. But the tube drainage often fails if the fluid is loculated. Intrapleural Streptokinase has been used in multiloculated empyemas with good success rate. We evaluated the efficacy and safety of intra-pleural Streptokinase in loculated empyemas. METHODS: A total of 15 patients admitted in Pulmonology unit with multiloculated empyemas whose drainage via drainage tube was less than 100 ml during the last 24 hours were included in the study. Aliquots of 250,000 units of Streptokinase in 100 ml of normal saline were instilled into the pleural cavity and the tube clamped for 3 hours. Response was assessed by clinical outcome, measurement of drain output after unclamping and subsequent chest radiography and serial chest ultrasounds. RESULTS: Streptokinase enhanced drainage in all patients with complete resolution of Empyema in 13 patients. Two patients with thickened visceral pleura following empyema drainage were referred to thoracic surgeon for decortication. The number of instillations of Streptokinase per patient ranged from 1 to 3 and the volume of drained empyema fluid ranged from 60 ml to 600 ml per patient. Streptokinase was well tolerated in all patients. CONCLUSION: Intrapleural Streptokinase is a safe and effective means of increasing the tube drainage in multiloculated Empyema without causing systemic fibrinolysis.
