Background There are many reports of Achilles tendon lengthening procedures for equinus deformity of the ankle. We previously modified an Achilles tendon lengthening to prevent overextension with a locking mechanism suture before performing a sliding lengthening. The purpose of this study was to compare the biomechanical properties of the locking mechanism suture with sliding lengthening (L-SL) and Z-lengthening (ZL) using a rabbit model. Methods Thirty-six male Japanese white rabbits were assigned to two groups - half undergoing the L-SL technique and half undergoing the ZL technique on the flexor hallucis longus (FHL) tendon. Six rabbits in each group were sacrificed at one week, three weeks, and six weeks postoperatively and evaluated, while five rabbits underwent radiographical and biomechanical evaluation and one underwent histological evaluation. Results In extension length, L-SL was significantly lower than ZL one week postoperatively. In the L-SL group, elongation one week postoperatively was significantly lower than that three and six weeks postoperatively. In the ultimate failure load, L-SL was significantly higher than ZL one and three weeks after lengthening. In the L-SL group, the ultimate failure load one week postoperatively was significantly lower than that three and six weeks postoperatively. In the ZL group, there were significant differences at all time points. Conclusion L-SL had higher mechanical property in vivo.Background Ultrasound-guided peripheral nerve block provides direct visualization of nerve and reduces the complications associated with classical landmark guided technique, by reducing the dosage of local anesthetic drugs. This study aims to determine the minimum effective volume (MEAV) of 0.75% ropivacaine for ultrasound-guided axillary brachial plexus block. Methodology A total of 23 patients of age group 18-75 years belonging to ASA grade 1, 2, and 3 were selected based on inclusion criteria. The MEAV was determined by using Dixons & Massey Step-up and Step-down method. The initial volume was selected as 15 mL based on previous studies. Depending on block success or failure, 1 mL of the drug was decreased or increased. Block was assessed in terms of motor and sensory components. The study was aborted after attaining five cases of block failure, followed by five cases of a successful block. Results The MEAV to be given for a successful block in 50% of patients (MEAV50) was 8.62 mL (95%CI 3.54-9.89). The MEAV to be given for a successful block in 90% of patients (MEAV 90) was 11.82 mL (95% CI 9.9-75.7). Conclusion Ultrasound guidance reduces the dosage of local anesthetic drugs to be used and provides surgical anesthesia without any complications or adverse effects.Ventricular assist device (VAD) pump thrombosis is a known complication and while the preferred standard treatment is surgical pump exchange this procedure is not without risk and for some patients the risks are prohibitive. This is a case of a 68-year-old female with bilateral HeartWare ventricular assist devices (HVAD) implanted as destination therapy who presented with signs of recurrent pump thrombosis. Surgical pump exchange was deemed to confer prohibitive risk due to her underlying medical co-morbidities and therefore not an option for treatment. After careful consideration of possible options for treatment, she received systemic thrombolysis (Alteplase 5 mg IV bolus followed by 3 mg/hour infusion for 10 hours through a central line) which was successful. This case highlights, not only the rarity of bilateral VADs as destination therapy, but also demonstrates the safety and efficacy of using systemic thrombolytics in patients with bilateral HVADs for treatment of pump thrombosis.Adamantinoma-like Ewing sarcoma (ALES) is a rare variant of Ewing sarcoma. It demonstrates heterogeneous morphologic pattern and complex immunophenotypic profile, with a peculiar combination of epithelial and neuroendocrine differentiation. ALES is rarely reported in the head and neck areas, including the parotid salivary gland. Till now, only 10 cases of ALES have been reported in the salivary glands. Herein, we report two cases of ALES involving the parotid gland, adding some valuable insight to the recently reported cases at this site.This is a report of rare cases of full-term infants born with persistent tunica vasculosa lentis (TVL) with no retinopathy of prematurity (ROP) and no plus disease. This condition can be mistaken with iris vascular enlargement-associated plus disease, leading to unnecessary laser or intravitreal injections. The cases were treated with close observation, which resulted in complete resolution of the TVL. In conclusion, we encourage the diagnosis of TVL and careful monitoring of such cases before the intervention, as the condition may revert completely.Introduction The prevalence of marijuana use has increased by about 16% since 2006, translating to approximately 200 million people worldwide. Being so widely used, long-term effects of marijuana use on cardiovascular health are largely unknown. Previous studies have had conflicting results, either showing marijuana use having a negative impact or no significant impact on cardiovascular health. This study aims to add evidence regarding the impact marijuana use has on the prevalence of cardiovascular disease. Methods This retrospective study was conducted using the Behavioral Risk Factor Surveillance System (BRFSS) database. Patients who completed the questionnaire and answered all questions in relation to marijuana use and the diagnosis of cardiovascular disease in 2017 were a part of this study. Subjects were excluded if they were children ( less then 18 years old) or had missing data for marijuana use or cardiovascular disease. Age, gender, race/ethnicity, body mass index (BMI), income, exercise, tobacco uslends support to the notion that marijuana use does not have an association with cardiovascular disease. A limitation in our study was that there was missing data from the BRFSS questionnaire due to participants not fully answering all questions concerning cardiovascular disease and marijuana use. This decreased our sample size from 67,974 to 56,742 subjects. The missing participants led to a decrease in the power of our odds ratio, which may have impacted statistical significance of our results. Conclusion Although previous literature has shown that marijuana use has a negative impact on cardiovascular health, our study suggests that users and non-users of marijuana did not have an association with the prevalence of cardiovascular disease. Varying levels of support within the literature highlights the need for further research of this association.

We report and analyze eight cases in which patients were referred from gastroenterology (GI) to otolaryngology following esophagogastroduodenoscopy (EGD). We aim to provide specific examples of head and neck pathology encountered by gastroenterologists during upper endoscopy.

A series of eight cases between 2016 and 2019 were analyzed by chart review. In each case, otolaryngology consultation was requested after an abnormality was noticed by a gastroenterologist during EGD. Subsequent laryngoscopy or bronchoscopy was performed in all cases allowing for image comparison.Select images comparing EGD to laryngoscopy findings are included as well as a literature review concerning the nature of communication between the two specialties.

Eight adult patients were referred to otolaryngology for abnormalities noted by a gastroenterologist during EGD at the following anatomic sites soft palate (n=1), base of tongue (n=2), glottis (n=3), and interarytenoid mucosa (n=1). Additionally, a potential airway foreign boder-specialty anatomic knowledge gaps were noted which contributed to occasional unnecessary referrals, procedures, and associated patient anxiety. We hope that the results of this study can inform future research aimed at improving communication and collaboration between the two specialties.Rothmund-Thomson syndrome (RTS) is an exceedingly infrequent genetic disorder characterized by a multitude of skin findings collectively known as poikiloderma. In normal cells, the RECQL4 gene is involved in DNA replication and repair. RTS is caused by a mutation in the RECQL4 gene, which results in increased predilection to develop various malignancies. Osteosarcomas and skin cancers are typically associated with this syndrome. We present a rare case of signet-ring cell gastric adenocarcinoma in a patient with RTS.Pulmonary tuberculosis (TB) is one of the top 10 leading causes of death in the world. Multi-drug resistant TB can lead to short-term and long-term sequelae causing clinical, psychosocial, and financial burden on the diseased. Pregnancy in a woman with compromised pulmonary function is a challenge for the treating obstetrician. A multidisciplinary approach involving a respiratory physician, pre-conceptional counseling, and delivery at a tertiary care center can reduce maternal morbidity and mortality. Compliance with anti-tubercular treatment with regular follow-up can minimize the long term effects of pulmonary TB. We report a case of unilateral lung collapse due to multidrug-resistant pulmonary TB in pregnancy with good maternal and fetal outcomes.Prescription drug use is a growing public health concern and studies show it is a contributing risk to motor vehicle collisions. The Appalachian region is also known to have an ever-increasing number of patients on controlled substances. This retrospective study of patients from the years 2011-2015 on controlled substances presenting to an Appalachian Level 1 trauma center after a motor vehicle or motorcycle collision was analyzed in order to determine the rate of opioid use among victims of motor vehicle collisions in the system, as well as evaluate for any differences in resource utilization between these patients and patients not using controlled substances. A total of 2,570 patients were included in the study. Seven-hundred sixty-eight (29.9%) individuals were found to be on a controlled substance. There was a similar mortality rate in both groups (2.8% vs 3.6%). There was no significant difference in hospital length of stay (LOS), intensive care unit (ICU) LOS, ventilator days, or injury severity score. Statistically significant findings include the type of crash (motor vehicle crash vs motorcycle crash) (p=0.003) and position in the vehicle (driver vs passenger) (p less then 0.001). Motor vehicle crashes and driver position were significantly associated with the presence of a controlled substance.Introduction Upper gastrointestinal bleeding (UGIB) is defined as any blood loss originating from the esophagus, stomach or the proximal duodenum above the ligament of Treitz. Ethnic trends regarding the causes of UGIB have been reported. The aim of this study was to identify the most common causes of UGIB among patients residing in Tabuk city, Saudi Arabia. Methods We have conducted a retrospective descriptive cohort study at King Fahad Specialist Hospital (KFSH), Tabuk, Saudi Arabia. All adult patients above the age of 18 years who were suspected of UGIB and referred for esophagogastroduodenoscopy (EGD) were included. The collected data included age, sex, nationality, complaint, EGD, and histopathologic findings. Birinapant ic50 Results Between January 1, 2017 and December 31, 2019, 73 patients were included. 83.6% were Saudi, and 64.4% were males. Hematemesis was the main complaint (65.8%). Esophagogastroduodenoscopy was normal in 6.84% of cases; however, it showed UGIB due to esophageal and gastric varices (9.57%) as well as non-variceal causes (83.
