This is an unusual case of an obstructive rectal squamous cell carcinoma (SCC), causing perforation and a pelvic abscess, requiring source control and diverting colostomy. A 50-year-old female with chronic constipation presented with worsening right buttock pain for 1 month. On exam, the patient reported right hip tenderness. A computer tomography (CT) revealed rectal wall thickening with a presacral abscess. Due to the concern of rectal perforation with abscess she was taken to the operating room for proctoscopy with biopsy, colostomy diversion and drainage of the abscess over the right buttock. Pathology reported invasive rectal SCC. Rectal SCC presents similarly to rectal adenocarcinoma but its diagnosis must include special markers for cytokeratins. The treatment approach is controversial but adequately treated offers better survival than rectal ADC. Rectal SCC is rare and treated with chemoradiation however it must also be tailored to the variable acute presentations.Multiple myeloma is a hematologic malignancy frequently presenting with spinal lytic lesions. The authors report the case of a patient with an extensively destructive osteolytic MM lesion in the cervical spine treated exclusively with radiotherapy. Computed tomography and magnetic resonance imaging scans showed an arrest of further progression of instability and resolution of the lytic lesion, showing signs of new bone formation. Whereas surgery should be considered for cases of spinal instability and potential neurological injury, this case demonstrates that isolated radiotherapy can be used in select cases to treat MM lesions and restore the structural integrity of the spinal elements.This case of bowel obstruction with multiple postoperative complications provides unique insight into the challenges faced by providers caring for intellectually disabled patients with acute surgical abdominal pathology and poor compliance. In this case, the component separation was utilized as a method of facilitated wound closure and compliance in a postoperative course highlighted by both dehiscence and wound infection. The patient, only able to communicate the presence of abdominal pain due to his disability, was surgically managed for a bowel obstruction secondary to a cecal volvulus. Gefitinib The difficulty in initial communication and patient noncompliance help illustrate the individualized care these patients require. This report will demonstrate both the challenges present in the management of intellectually disabled patients with abdominal wounds, as well as the use of component separation in providing both initial wound closure and continued wound integrity with the goal of reducing postoperative complications in patients with decreased compliance.Liposarcoma is one of the common soft tissue tumors but barely arises from the mediastinum. Complete surgical resection with a negative surgical margin is required for the treatment; however, mediastinal liposarcomas tend to be large due to its slow-growing nature. A 57-year-old man was referred to us for having an abnormal mediastinal shadow in a chest X-ray. Computed tomography scanning revealed a giant posterior mediastinal tumor, completely involving the esophagus. Because of the unusual size and location of the tumor, we took a bilateral video-assisted thoracoscopic approach. First, the soft lipomatous compartment of the tumor was dissected from the esophagus and the descending aorta via the left thoracic cavity complete thoracoscopic procedure. Then, the patient was placed in the left lateral position, and the solid part of the tumor was completely resected using 13 cm of right-side thoracotomy. There was no complication or local recurrence in the first 26 months of follow-up.Intussusception is an infrequent cause of mechanical bowel obstruction in adults and surgical resection is warranted in most cases. Small bowel is a common site of recurrence from cutaneous melanoma but early diagnosis is still a challenge. Acute peritonitis, haemorrhage and obstruction are known clinical presentations. Wide surgical excision with free margins and accompanied mesentery is the treatment of choice and may improve the prognosis. We present a case of small bowel obstruction due to three intussusceptions by metastatic malignant melanoma submitted to surgery.

Freezing of gait (FOG) is a debilitating and incompletely understood symptom in Parkinson's disease (PD).

To determine the principal clinical factors predisposing to FOG in PD, their interactions, and associated nonmotor symptoms.

164 PD subjects were assessed in a cross-sectional retrospective study, using the MDS-UPDRS scale, MMSE, and Clinical Dementia Rating Scale. Clinical factors associated with FOG were determined using univariate analysis and nominal logistic regression. Receiver operating characteristic curves were computed, to obtain measures of sensitivity and specificity of predictors of FOG. Subgroups of patients with FOG were compared with those without FOG, based on defining aspects of their clinical phenotype.

Relative to non-FOG patients, those with FOG had a longer disease duration, higher PIGD and balance-gait score, higher LED, and more motor complications (

< 0.0001) and were more likely to exhibit urinary dysfunction (

< 0.0003), cognitive impairment, hallucinations, antor fluctuations. These findings may help to inform clinical management and highlight distinct subgroups of patients with PD-FOG, which are likely to differ in their network pathophysiology.Social cognition (SC) deficits have been linked to Parkinson's disease (PD) but have been less well researched than general cognitive processes, especially in early-onset PD (EOPD), despite this population often having greater social and family demands. Most studies focus on recognition of facial emotion, theory of mind (ToM), and decision-making domains, with limited research reporting on social reasoning. The main objective of this work was to compare SC ability across four domains emotional processing, social reasoning, ToM, and decision-making between patients with EOPD and healthy controls. Twenty-five nondemented patients with EOPD and 25 controls matched for sex, age, and educational level were enrolled. A battery that included six SC tests was administered to all study participants; a decision-making scale was completed by participants' partners. Statistically significant differences were found between patients with EOPD and controls in all subtests across the four SC domains studied. The EOPD group demonstrated worse performance on all tasks, with large effect sizes.
