Schizophrenia following new-onset refractory status epilepticus secondary to antiphospholipid syndrome

New-onset refractory status epilepticus (NORSE) is a drug-resistant status epilepticus that often has a catastrophic outcome. Our patient was diagnosed with NORSE and had an EEG reading that showed status epilepticus persisting for 8 months in general anesthesia. After autoimmune workup showed positive antiphospholipid antibodies, his seizure was controlled, and he was discharged with good condition apart from moderate cognitive impairment. However, he later developed schizophrenia. Although psychiatric disorders have been associated with antiphospholipid syndrome, to the best of our knowledge, it has not been reported to be associated with status epilepticus. We recommend vigilance of psychological complications of refractory status epilepticus’ patients for early psychiatric referral, diagnosis, and treatment.

New-onset refractory status epilepticus (NORSE) is a syndrome of new-onset drug-resistant status epilepticus that often has a catastrophic outcome. Epilepsy is usually associated with psychiatric disorders of different manifestations of which psychosis is an example.1 However, not much is found in the literature review regarding psychiatric disorders following NORSE although a recent study concluded 32% of NORSE patients ended up with altered behavioral states like aggression.2 Schizophrenia following NORSE like in the rare presentation of this case has not been reported in the literature review before, although an association between schizophrenia and autoimmune disorders like APS has been reported.3

Isolated medial cuneiform fractures: report of two cases and review of the literature

Although fractures of the midfoot are common, cuneiform fractures are rarely seen. These fractures are frequently associated with other fractures of the midfoot such as Lisfranc fracture-dislocations. However, isolated cuneiform fractures are extremely rare, with few cases reported in the relevant literature. Herein, the authors report 2 cases of isolated medial cuneiform fractures. One of the patients was treated with headless screw fixation due to displacement in fracture configuration, and the other was treated conservatively. Fractures were united without any complication in both patients. In this report, the authors discuss the mechanism of injury, diagnostic challenges, and treatment options of isolated medial cuneiform fractures.     

Isola spinal instrumentation system for idiopathic scoliosis

Since the definition of three-dimensional components of the scoliotic deformity, there have been important improvements in the surgical treatment of the problem. A derotation maneuver was proposed as a treatment option with CD instrumentation, but the reports of imbalance and decompensation with this system repopularized sublaminar wiring and translation as a corrective maneuver. Isola spinal instrumentation is one of the modern systems that utilizes vertebral translation instead of rod rotation. This study analyzes the results of 24 patients with idiopathic scoliosis who had been followed up for at least 2 years, and were surgically treated with titanium Isola Spinal Instrumentation in the Department of Orthopaedics and Traumatology, Ankara Social Security Hospital. Patients were grouped according to the King-Moe classification. Patients with type III, IV or V curves received only posterior instrumentation while this procedure followed anterior release and discectomy in the same session in patients with type I or II curves. A translation maneuver was utilized in the correction of scoliotic curves using the cantilever technique, either alone or supplemented by sublaminar wiring with Songer multifilament titanium cables. This study aimed to elucidate the effects of this technique in the frontal and sagittal plane curves and the trunk balance. The balance was analyzed clinically and radiologically by measurement of the lateral trunk shift (LT), shift of stable vertebra (SS), and shift of head (SH) in vertebral units (VU). The postoperative correction was significant in the frontal plane for all types of curves (p < 0.05). The postoperative correction was 80.9% +/- 9.5% in type III curves. Overall, the mean Cobb angle of the major curve value in the frontal plane was 66.9 degrees +/- 18.8 degrees, and it was corrected by 62.8% +/- 20.1%. The correction loss of Cobb angles in the frontal plane was 5.4 degrees +/- 5.5 degrees at the last follow-up visit. A normal physiologic thoracic contour (30 degrees - 50 degrees) was achieved in 83.3% of the patients and normal lumbar contour (40 degrees - 60 degrees) in 66.7% of the patients in the sagittal plane. The correction was found to be significant in all balance values (p < 0.05). The postoperative correction in LT values correlated with the correction of the Cobb angle values in the frontal plane. All patients had complete balance (SH: 0 VU and SS: 0 VU) or balanced curves (0 VU < SH, SS < 0.5 VU).Finally, the study concluded that the translation maneuver, especially when used with the cantilever technique, resulted in high correction rates in the frontal plane. Additionally, the technique was also successful in obtaining normal sagittal contours and correcting balance values.     

Waiting for lung transplantation: quality of life, mood, caregiving strain and benefit, and social intimacy of spouses

BACKGROUND: The emotional and physical well-being of lung transplant patients is enhanced by the availability and stability of a primary caregiver. METHODS: We describe the quality of life (QOL), mood, caregiving strain and benefits, and social intimacy of 73 lung transplant caregivers who completed the QOL Inventory, SF-36 Health Survey, Profile of Mood States, Caregiver Strain Index, Caregiver Benefit Index, and Miller Social Intimacy Scale. RESULTS: Clinically low QOL was reported by 17.8-35.6% of spouses. Relative to a normative sample, spouses reported significantly lower physical (z = 4.01, p < 0.001) and emotional (z = 7.01, p < 0.001) QOL. Over half (56.2%) had clinically elevated caregiving strain. Heightened physical strain (80.8%), inconvenience (79.5%), feeling confined (72.6%), feeling upset that patient has changed so much (69.9%) contributed most to caregiver strain, while discovering inner strength (60.3%), support from others (53.4%), and realizing what is important in life (42.5%) were noted caregiving benefits. Higher caregiving strain was associated with more mood disturbance (r = 0.42, p < 0.001), lower emotional QOL (r = -0.39, p < 0.002), lower social intimacy (r = -0.37, p < 0.002), and longer disease duration (r = 0.55, p < 0.001). CONCLUSION: Spouses of patients awaiting lung transplantation may experience QOL deficits and high caregiver strain. Interventions to improve QOL and reduce caregiver strain are needed.     

Inter- and intraobserver reliability of the Crowe and Hartofilakidis classifications in the assessment of developmental dysplasia of the hip in adult patients

Background

The purpose of this study is to investigate the inter- and intraobserver reliability of Crowe and Hartofilakidis classifications in the assessment of developmental dysplasia of the hip in adult patients.

Materials and methods

Two consultant orthopedic surgeons classified 141 dysplastic hips on 103 standard anterior–posterior pelvis radiographs according to the Crowe and Hartofilakidis classifications. Assessments were performed in random order by each observer on two separate occasions, at least 4?weeks apart. Kappa statistics were used to establish a relative level of agreement between observers for the two readings and between separate readings by the same observer.

Results

At the first readings, interobserver reliability analysis revealed kappa coefficient of 0.71 for the Crowe classification and 0.54 for the Hartofilakidis classification. At the second reading, the kappa coefficient was 0.72 for the Crowe classification and 0.75 for the Hartofilakidis classification. Intraobserver reliability analysis revealed kappa coefficients of 0.71 for the Crowe and 0.80 for the Hartofilakidis classification for observer A, and 0.76 and 0.70 for observer B.

Conclusions

In conclusion, we have found substantial inter- and intraobserver agreement for Crowe classification and substantial to moderate agreement for Hartofilakidis classification in this study. Both classification systems assess the different aspects of developmental dysplasia of hip in adults. Each system has advantages and disadvantages. We suggest using both of these classifications together to increase the accuracy.     

Developing fMRI protocol for clinical use Comparison of 6 Arabic paradigms for brain language mapping in native Arabic speakers

Objectives:To assess a baseline assessment using developed functional magnetic resonance imaging (fMRI) language paradigms for Arabic-speakers.Methods:24-healthy right-handed volunteers scanned on a 3.0 Tesla MRI machine. For fMRI, a BOLD-sensitive sequence used to measure signals over time across 6 language paradigms: rhyming (RH), semantic category generations (SCG), silent word generation (SWG), verb generation picture (VGp), verb generation word (VGw), and verb generation audio (VGa). fMRI data was analyzed using FMRIB Software Library (FSL).Results:We found that VGa, SWG, VGw and VGp robustly activated language-related regions in the dominant hemisphere. RH and SCG failed to adequately define these activation regions but this may be related to the study’s preliminary nature and limitations. After assessment of their validity, considerable activation of the inferior frontal gyrus during VGa, SWG, VGw and VGp suggests that these paradigms have the potential for localizing of Broca’s area in native Arabic speakers.Conclusion:Set of well adapted, and evidence-based, fMRI paradigms were established for Arabic-speakers to enable accurate and sufficient localization and lateralization of the language area. After validation, these paradigms may provide sequences for accurate localization of brain language areas, and could be used as a presurgical evaluation tool.

Functional magnetic resonance imaging (fMRI) allows precise, and non-invasive, localization and lateralization of brain functions. Clinically, these techniques have considerable success, and hold great potential in the management of a variety of neurological disorders. One of the most promising clinical applications of fMRI is presurgical linguistic mapping.1-5 The 3 classical language areas that are involved in language production and processing are Broca’s and Wernicke’s areas, and angular gyrus. Wernicke’s area can be described as a receptive region, for processing and integrating auditory sensory information, while Broca’s area can be described as a productive region, for making vocal signals, and meaningful words or sentences. The latter includes pars opercularis and triangularis. The angular gyrus area is particularly involved in reading and transitioning between written and spoken forms of language. Injury to language regions produces noticeable clinical deficits, and the location of these regions may become difficult to assess without advanced anatomical imaging such as fMRI. Internationally, fMRI replaces the more invasive Wada test (also known as the intracarotid sodium amobarbital procedure) in lateralizing language and memory at some centers.6,7Language is a highly complex system that markedly varies across individuals. Patients native language affects brain activation responses during fMRI scans.8-13 As such, language paradigms for presurgical fMRI mapping should be developed and validated using native language paradigms. Language dominance of the left cerebral hemisphere has been well researched and established, but native language and social factors were also reported to play a key role in cortical association of verbal processing.8,14-16Although language localization using fMRI has been routinely used in western countries, and more recently in an Arabic country,17 studies clearly demonstrated that different cultures may process language in different manners, using different brain mechanisms.8,14-16 Existing language paradigms, created for non-Arabic speaking patients, require major modifications before applying them in examining native Arabic speakers.17Language lateralization is another broadly used clinical application of fMRI. Concordance with Wada test has long been demonstrated and validated in the literature using paradigms with various tasks such as verbal fluency, comprehension, and semantic judgment .18-21 These have shown that concordance with Wada test can reach 90% in temporal lobe epilepsy, especially in left-dominant patients. A slightly lower concordance was achieved in right-dominant patients. Although fMRI language lateralization works well for patients with typical language dominance, clinicians need to be careful when interpreting results of patients with atypical language representation.22Semitic languages such as Arabic differ from other languages in many aspects, including orthography (including diacritics), phonology, and syntax. Therefore, significant research in developing and validating language paradigms for Arabic is required. To our knowledge, very few studies in this domain have been carried out.17,23 One developed several language and memory paradigms in neurological patients, while emphasizing consideration for educational and cultural adjustments,17 and the other examined neuronal correlates of diacritics (vs. lack of thereof) in 11 healthy men.23We aim to establish tasks adapted to the Arabic language, that also reliably activate Broca’s and Wernicke’s areas in a relatively short scanning time. This study is a baseline assessment using 6 developed fMRI language paradigms for Arabic-speaking presurgical candidates. The desired outcome of this work is to create a set of Arabic language localization protocols, along with standard operating procedures.     

Impact of body weight on long-term survival after lung transplantation

STUDY OBJECTIVES: The purpose of this study was to determine the impact of a pretransplantation determination of body mass index (BMI) on survival after lung transplantation. DESIGN AND PATIENTS: Univariate and multivariate survival analyses of a single institution database consisting of 85 patients who had undergone lung transplantations between March 1994 and October 1998. SETTING: University of Florida Health Science Center. RESULTS: Kaplan-Meier survival curves showed that patients who were obese (ie, BMI, > or = 30) at a pretransplantation assessment had a marked decrease in posttransplantation survival time (log rank, p < 0.05; Wilcoxon, p < 0.05). The final Cox regression model revealed that the most powerful predictors of mortality after lung transplantation were higher pretransplantation BMI and the development of obliterative bronchiolitis. CONCLUSIONS: Our results suggest that the posttransplantation risk for mortality is possibly three times greater for obese patients than for nonobese patients. Additional study is needed to identify the mechanisms for such higher risk in obese patients. Our data also suggest that transplantation centers should not routinely reject underweight patients (ie, BMI, < 18.5) or overweight patients (ie, BMI, 25 to 29.9) for lung transplantation listing solely on the basis of weight, as their outcomes may not be significantly different than patients with normal BMIs.
