IntroductionAlcohol-induced psychotic disorder (AIPD), is an uncommon complication of alcohol abuse. AIPD needs to be distinguished from alcohol withdrawal delirium and schizophrenia and the underlying pathophysiology is poorly understood. Few brain-imaging studies in AIPD have been reported to date. Case reports of brain-imaging in AIPD suggest possible dysfunction in the thalamus, basal ganglia, frontal lobes and cerebellum. The aim of this study was to compare resting brain perfusion (rCBF) in patients with AIPD, uncomplicated alcohol dependence, schizophrenia and healthy volunteers.MethodsSingle photon emission computed tomography (SPECT) was utilized to compare rCBF in patients with AIPD (n = 19), schizophrenia (n = 16), uncomplicated alcohol dependence (n = 20) and healthy volunteers (n = 19).ResultsIncreased rCBF was demonstrated in the right calcarine area in patients with AIPD compared to healthy volunteers, with a trend towards increased rCBF to the frontal and temporal lobes and the right pallidum. Decreased left sided rCBF to the putamen, parietal, mid-frontal and mid-temporal lobes and heterogenous flow to the cerebellum were demonstrated in patients with AIPD when compared to patients with uncomplicated alcohol dependence. The left posterior cingulate and right cerebellum showed higher and lower rCBF respectively in patients with AIPD compared to patients with schizophrenia.ConclusionThe findings implicate the right occipital lobe and possibly the cerebellum in the pathogenesis of AIPD. Some findings have similarities with rCBF reports in alcohol-withdrawal. Reduced rCBF to the frontal lobes, thalamus and basal ganglia in AIPD as suggested in previous case reports could not be confirmed.

Abstract Background: Hemi chorea and hemiballismus interestingly, are rare presentations of severe chronic persistent hyperglycemia which resolves with correction of hyperglycemia in most cases. Clinical Case: Here we report a case of a 67 YO woman with a PMH of prolonged uncontrolled DM evidenced by average baseline HbA1c of 14.6% (n<5.7%) presenting with dance-like movements of the left arm and mouth deviation. Initially the patient presented as a stroke code. Vital signs were unremarkable. On Physical exam, there was mild L face weakness and obvious abnormal hand movement. Other neurological exams were unremarkable for stroke. MRI showed the typical decreased T2/flair signal within the right frontal lobe, white matter, right caudate head, and bilateral lenticular nucleus with mild increased T1 signal of the right caudate and lenticular nucleus compatible with hyperglycemic nonketotic hemichorea hemiballismus. Her significant admission lab values of random blood glucose of 306mg/dl (n 74-200mg/dl), HbA1c of 18.7% (n<5.7%), urine sugar >1000 (n neg mg/dl), absence of ketonuria and acidosis also support the diagnosis. With improvement in her blood sugar control, there was a significant decrease in her abnormal hand movements. However, sugar control was not enough as there was the need for additional medications to improve the chorea such as risperidone and tetrabenazine. Eventually over the course of many months of tight glucose control, there was significant symptomatic improvement. While the exact etiology is unclear, the hyperintensity usually seen on head CT scan and the pathognomonic T1 hyperintensity of the basal ganglia on MRI is postulated to be related to metabolic abnormalities caused by hyper viscosity of the blood in the end arteries supplying the basal ganglia. Many case reports associated movement disorders to chronic persistent hyperglycemia but there are many other cases that described hemiballismus in acute cases of hyperglycemia or persisting despite adequate glycemic correction. Most of the patients described had an underlying markedly elevated HbA1c as a common factor which suggests that a prolonged period of uncontrolled hyperglycemia may be necessary to produce hemiballismus. When thinking of complications of diabetes, we often think of CAD, ESRD, CVD, DKA and HHS. We aim to create an awareness of this rare association and to recognize hemiballismus as one of the varying presentations of severe hyperglycemia in order to ensure early diagnosis and treatment of this condition. Conclusion: Hemichorea and hemiballismus are increasingly becoming popular as one of the many complications of severe chronic or acute hyperglycemia. This warrants recognition in literature.

Few case reports of encapsulated intracranial hematoma (EIH) exist, and the mechanisms underlying the onset and enlargement of EIH remain unclear. Here, we report on a 39-year-old woman with an EIH that repeatedly hemorrhaged and swelled and was ultimately surgically removed. In June 2012, the patient visited her local doctor, complaining of headaches. A magnetic resonance imaging (MRI) scan identified a small hemorrhage of approximately 7 mm in her right basal ganglia, and a wait-and-see approach was adopted. Six months later, her headaches recurred. She was admitted to our department after MRI showed tumor lesions accompanying the intermittent hemorrhaging in the right basal ganglia. After admission, hemorrhaging was again observed, with symptoms progressing to left-sided hemiplegia and fluctuating consciousness; thus, a craniotomy was performed. No obvious abnormal blood vessels were observed on the preoperative cerebral angiography. We accessed the lesion using a transcortical approach via a right frontotemporal craniotomy and removed the subacute hematoma by extracting the encapsulated tumor as a single mass. Subsequent pathological examinations showed that the hematoma exhibited abnormal internal vascularization and was covered with a capsule formed from growing capillaries and accumulating collagen fibers, suggesting that it was an EIH. No lingering neurological symptoms were noted upon postoperative follow-up. This type of hematoma expands slowly and is asymptomatic, with reported cases consisting of patients that already have neurological deficits due to progressive hematoma growth. Our report is one of a few to provide a clinical picture of the initial stages that occur prior to hematoma encapsulation.

Abstract Background Pulmonary artery catheter insertion is a routine practice in high-risk patients undergoing cardiac surgery. However, pulmonary artery catheter insertion is associated with numerous complications that can be devastating to the patient. Incorrect placement is an overlooked complication with few case reports to date. Case presentation An 18-year-old male patient underwent elective mitral valve replacement due to severe mitral valve regurgitation. The patient had a history of synovial sarcoma, and Hickman catheter had been inserted in the right internal jugular vein for systemic chemotherapy. We made multiple attempts to position the pulmonary artery catheter in the correct position but failed. A chest radiography revealed that the pulmonary artery catheter was bent and pointed in the cephalad direction. Removal of the pulmonary artery catheter was successful, and the patient was discharged 10 days after the surgery without complications. Conclusions To prevent misplacement of the PAC, clinicians should be aware of multiple risk factors in difficult PAC placement, and be prepared to utilize adjunctive methods, such as TEE and fluoroscopy.

Postoperative complications after brain tumor surgery occur occasionally and it is important for clinicians to know how to properly manage each complication. Here, we described a rare case of late-onset, subdural fluid collection localized at the resection cavity that caused motor weakness after convexity meningioma resection, requiring differentiation from an abscess, to help clinicians determine treatment strategies. A 58-year-old right-handed female was admitted to the hospital with a headache and posterior neck pain. Brain computed tomography (CT) scans and magnetic resonance (MR) images showed a homogeneously enhanced, calcified, and multi-lobulated mass adjacent to the right motor strip without perilesional edema. The patient underwent surgery without incident or residual deficit and was discharged from the hospital in good condition. Six weeks after surgery, the patient complained of left arm monoparesis without infection-related symptoms. Brain imaging studies showed a localized fluid collection in the resection cavity with an enhanced margin and perilesional edema. Diffusion restriction was not detected. After three months of conservative treatment without surgery or antibiotics, she recovered from the neurologic deficits, and brain imaging studies showed the spontaneous regression of the fluid collection and perilesional edema. Late-onset, localized fluid collection at the resection cavity, which is similar to an abscess, could occur three to eight weeks after meningioma resection. When there are predisposing factors, including blood components and hemostatic materials in the surgical cavity, it is important for clinicians to understand this type of complication and choose conservative management as a feasible strategy.

Abstract Introduction Traumatic head injury with extradural hematoma (EDH) is seen in 2% of patients. Development of EDH on the contralateral side is an uncommon complication that has been reported in various case reports. Case Report We report here a case of an 18-year-old male who had a road traffic injury. He was diagnosed as a case of left-sided large frontotemporoparietal acute extradural bleed with a mass effect toward the right side. He was managed with urgent craniotomy and evacuation of hematoma. A noncontrast computed tomography (NCCT) scan performed 8 hours after postoperative period showed a large frontotemporoparietal bleed on the right side with a mass effect toward the left side. He was again taken to the operating room and right-sided craniotomy and evacuation of hematoma were performed. A postoperative NCCT scan revealed a resolved hematoma. The patient made a complete recovery in the postoperative period and is doing well. Conclusion Delayed onset epidural hematoma is diagnosed when the initial computed tomography (CT) scan is negative or is performed early and when late CT scan performed to assess clinical or ICP deterioration shows an EDH. The diagnosis of such a condition requires a high index of suspicion based on the mechanism of injury along with fracture patterns. Additionally, change in pupillary size, raised intracranial pressure, and bulging of the brain intraoperatively are additional clues for contralateral bleeding. Neurologic deterioration may or may not be associated with delayed EDH presentation. An early postoperative NCCT scan within 24 hours is recommended to detect this complication with or without any neurologic deterioration.

To determine whether the echocardiographic presentation allows for diagnosis of acromegalic cardiomyopathy. 140 patients with acromegaly underwent echocardiography as part of routine diagnostics. The results were compared with the control group comprising of 52 age- and sex-matched healthy volunteers. Patients with acromegaly presented with higher BMI, prevalence of arterial hypertension, and glucose metabolism disorders (i.e., diabetes and/or prediabetes). In patients with acromegaly, the following findings were detected: increased left atrial volume index, increased interventricular septum thickness, increased posterior wall thickness, and increased left ventricular mass index, accompanied by reduced diastolic function measured by the following parameters: E’med., E/E’, and E/A. Additionally, they presented with abnormal right ventricular systolic pressure. All patients had normal systolic function measured by ejection fraction. However, the values of global longitudinal strain were slightly lower in patients than in the control group; the difference was statistically significant. There were no statistically significant differences in the size of the right and left ventricle, thickness of the right ventricular free wall, and indexed diameter of the ascending aorta between patients with acromegaly and healthy volunteers. None of 140 patients presented systolic dysfunction, which is the last phase of the so-called acromegalic cardiomyopathy. Some abnormal echocardiographic parameters found in acromegalic patients may be caused by concomitant diseases and not elevated levels of GH or IGF-1 alone. The potential role of demographic parameters like age, sex, and/or BMI requires further research.

Objective: We report a case of self inserted needle into the left ventricle of the heart and a description of our surgical intervention in a psychiatric patient without decision-making capacity. We discuss issues regarding obtaining consent in this patient with a sub-acute presentation, report our operative approach, and summarize a treatment approach based on a review of current literature. Methods: A PubMed search using terms “needle, “heart”, “insertion”, “intracardiac foreign object”, yielded 69 relevant papers. 67 of these were case reports yielding 72 individual cases. Age, gender, cause of the needle entry (Accidental Plus (A+), Intravenous Drug User [IVDU], Self-inflicted (SI)), type of needle, location in heart, neuropsychiatric history, treatment, and outcome were documented. Results: Within the SI category, there were a total of 28 cases, 89.3% had a neuropsychiatric history whereas only there were only 2 such patients in both the IVDU and A+ group. The location of the needle in the heart in all 72 cases was as follows: right ventricle 40.3%, other 20.8%, left ventricle 19.4 %, ventricle and interventricular septum 16.7% and the right and left atrium were each 1.4 %. In all three groups (n=72), 77.8% of patients underwent surgery, with 92.9% having a stable outcome. Conclusion: Our case and review demonstrates that management of such cases, particularly when active mental health issues are present, requires a case-by-case evaluation and treatment as a specific standard of care has not been established. Surgical intervention appears to be the preferred management regardless of presentation with good outcomes. Running Title: Intracardiac Self Insertion of a Darning Needle in a Psychiatric Patient

In the natural world, we experience and adapt to multiple extrinsic perturbations. This poses a challenge to neural circuits in discriminating between different context-appropriate responses. Using event-related fMRI, we characterized the neural dynamics involved in this process by randomly delivering a position- or velocity-dependent torque perturbation to subjects’ arms during a target-capture task. Each perturbation was color-cued during movement preparation to provide contextual information. Although trajectories differed between perturbations, subjects significantly reduced error under both conditions. This was paralleled by reduced BOLD signal in the right dentate nucleus, the left sensorimotor cortex, and the left intraparietal sulcus. Trials included “NoGo” conditions to dissociate activity related to preparation from execution and adaptation. Subsequent analysis identified perturbation-specific neural processes underlying preparation (“NoGo”) and adaptation (“Go”) early and late into learning. Between-perturbation comparisons of BOLD magnitude revealed negligible differences for both preparation and adaptation trials. However, a network-level analysis of BOLD coherence revealed that by late learning, response preparation (“NoGo”) was attributed to a relative focusing of coherence within cortical and basal ganglia networks in both perturbation conditions, demonstrating a common network interaction for establishing arbitrary visuomotor associations. Conversely, late-learning adaptation (“Go”) was attributed to a focusing of BOLD coherence between a cortical–basal ganglia network in the viscous condition and between a cortical–cerebellar network in the positional condition. Our findings demonstrate that trial-to-trial acquisition of two distinct adaptive responses is attributed not to anatomically segregated regions, but to differential functional interactions within common sensorimotor circuits.
