Benign proliferations of smooth muscle cells are known as leiomyomas; these proliferations can occur in the colon and are typically found incidentally. Colonic leiomyomas are very rare and are most commonly found in the descending or sigmoid colon. A 59-year-old Hispanic female presented to the gastroenterology clinic for surveillance colonoscopy. The biopsy showed a submucosal microscopic leiomyoma in the transverse colon. The treatment of choice for most colonic leiomyomas is surgical excision. This rare case favors the notion that endoscopic polypectomy may be superior to surgical excision, ultimately providing a lessinvasive and less-costly procedure without complications or recurrence.

We aim to study the impact of pulmonary hypertension (PH) on acutely exacerbated chronic obstructive pulmonary disease (AECOPD). We used the 2016 and 2017 National Readmission Database with an inclusion criterion of AECOPD as a primary and PH as a secondary diagnosis using ICD 10-CM codes. Exclusion criteria were age under 18 years, non-elective admission, and discharge in December. The primary outcome was in-hospital mortality during the index admission. Secondary outcomes were 30-day readmission rate, resource utilization, and instrument utilization including intubation, prolonged invasive mechanical ventilation >96hr (PIMV), tracheostomy, chest tube placement, and bronchoscopy during the index admission. A total of 627,848 patients with AECOPD were included in the study, and 68,429 (10.90 %) patients had a diagnosis of PH. PH was more common among females (61.14%) with a mean age of 71 ±11.66, Medicare recipients (79.5%), higher Charlson Comorbidity Index, and treatment in an urban teaching hospital. PH was associated with greater mortality [adjusted odds ratio (aOR): 1.89, p<0.001], higher 30-day readmission (aOR-1.24, p<0.001), higher cost [adjusted mean difference (aMD: $2785, p<0.01], LOS (aMD-1.09, p<0.001) and higher instrument utilization including intubation (aOR: 199, p<0.001), PIMV (aOR: 2.12, p<0.001), tracheostomy (aOR-2.1, p<0.001), bronchoscopy (aOR-1.46, p=0.007) and chest tube placement (aOR-1.39 p<0.004). We found that PH is related to higher in-hospital mortality, LOS, increased instrument utilization, readmission, and costs. Our study aims to shed light on the impact of PH on AECOPD in hopes to improve future management.

Wallenberg syndrome is the most common stroke of the posterior circulation. Diagnosis of Wallenberg syndrome is often overlooked as initial MRI may show no visible lesion. We present an atypical case of Wallenberg syndrome in which the initial MRI of the brain was normal.Our patient is a 65-year-old male who was brought in by emergency medical services complaining of rightsided facial droop, slurred speech, and left-sided weakness for one day. Physical examination showed decreased left arm and leg strength compared to the right side, decreased left facial temperature sensations, decreased left arm and leg temperature sensations, and difficulty sitting upright with an associated leaning towards the left side. An initial magnetic resonance imaging (MRI) of the brain with and without contrast revealed no abnormality. In light of such a high suspicion for stroke based on the patient's neurologic deficits, a repeat MRI of the brain was performed three days later and exposed a small focus of bright signal (hyperintensity) on T2-weighted fluid-attenuated inversion recovery and diffusion-weighted imaging (DWI) in the left posterior medulla.Wallenberg syndrome, also known as lateral medullary syndrome or posterior inferior cerebellar artery syndrome, is a constellation of symptoms caused by posterior vascular accidents. The neurological deficits associated with this disease are due to damage of the lateral medulla, inferior cerebellar peduncle, nucleus of trigeminal nerve, nucleus and fibers of vagus and glossopharyngeal nerves, descending sympathetic tract, spinothalamic tract, and/or vestibular nuclei. MRI with DWI is the gold standard to confirm the diagnosis.Wallenberg syndrome has the potential to leave patients extremely debilitated. Early detection, management, and rehabilitation are critical for improving post-stroke recovery.
