Reexamination of the characteristics of the deficit schizophrenia patients

The aim of this study was to reexamine and compare the characteristics of the deficit and nondeficit schizophrenic patients. This cross-sectional study consisted of 62 in- and out-patients, 18–65 years of age, diagnosed with schizophrenia according to DSM-IV. The sociodemographic variables, premorbid adjustment, clinical course and general functioning level in the past five years were evaluated by utilizing the appropriate sections of Comprehensive Assessment of Symptoms and History (CASH). In addition, GAF, the Schedule for the Deficit Syndrome (SDS), Positive and Negative Syndrome Scale (PANSS), Montgomery Äsberg Depression Scale (MADRS), the Neurological Evaluation Scale (NES) and the Simpson Angus Extrapyramidal Side Effects (EPS) Rating Scale, Trail A and B, Verbal Fluency, Stroop, Block Design and Finger Tapper tests were administered. Using the SDS, 19 patients (30.6 %) were categorized as deficit; 43 (69.4 %) were categorized as nondeficit. The deficit patients were worse on the Functioning During Past Five Years score of CASH. The PANSS and MADRS mean scores were not significantly different between the two groups, except a higher level of negative symptoms observed in the deficit group. NES scores were also significantly higher in the deficit group. However, sociodemographic and other clinical variables, neurocognitive measures and EPS symptoms did not show any significant difference between the two groups. Our findings suggest that the deficit schizophrenia is a distinct subgroup comprised of patients who have more negative symptoms, neurological impairment and poor functioning which may have a common underlying pathology.     

Childhood dystonia

Childhood dystonias are a heterogeneous group of disorders with strong inherited basis. This review describes the clinical characteristics, classification, genetic basis, pathophysiology, biochemistry, pathology, and treatment of dystonias, including the primary dystonias, the dystonia-plus syndromes, secondary dystonias, and heredodegenerative disorders. Conditions discussed in detail include idiopathic torsion dystonia, dopa-responsive dystonia, Wilson's disease, myoclonus dystonia, rapid-onset dystonia parkinsonism, neurodegeneration with brain iron accumulation (Hallervorden-Spatz syndrome), mitochondrial dystonias, Niemann-Pick type C, and neuroacanthocytosis.     

Ecthyma gangrenosum.

Case 1. An 18-year-old white man with AML-M3 received allogeneic bone marrow transplantation (BMT) in August 1997. On the seventh day of BMT, he developed chills, fever (39.1 °C), anorexia, and perirectal pain. On physical examination, a hemorrhagic bulla and “punched out” ulceration were observed on the perirectal region. Subsequently, the ulcer was surrounded by a red, swollen, tender, cellulitic plaque ( Fig. 1 ).

Multiple rice body formation accompanying the chronic nonspecific tenosynovitis of flexor tendons of the wrist

Rice body formation is generally a rare disorder related to rheumatoid arthritis. It can also be observed in cases of systemic lupus erythematosus, seronegative arthritis, infectious arthritis (tuberculosis, atypical mycobacterial infection), nonspecific arthritis, and osteoarthritis. It is generally located within joints or bursae. Multiple rice bodies of tendon sheaths are rarely encountered. Rice body formation may also be encountered without underlying systemic disorders. We present a case of multiple rice body formation that accompanied chronic nonspecific tenosynovitis of the flexor tendons of the wrist.     

A composite index for determining the impact of oral ulcer activity in Behcet's disease and recurrent aphthous stomatitis

Background:  Although number, frequency and healing time of oral ulcers and pain are generally used for clinical practice and studies in Behcet's disease (BD) and recurrent aphthous stomatitis (RAS), no standardized activity index is currently present to monitor clinical manifestations associated with oral ulcers. The aim of this study was to develop a standardized composite index (CI) to assess oral ulcer activity in BD and RAS.
Methods:  In this cross-sectional study, 121 patients with BD and 45 patients with RAS were included. Sixty-five percentage of BD and 68.9% of RAS patients were in active stage during the previous 3 months. The developed CI included the presence of oral ulcers, ulcer-related pain and functional status and was evaluated in patients with both active and inactive disease for content validity.
Results:  Composite index score was observed to be higher in active patients with RAS (6.94 ± 2.19) compared with active BD patients (6.01 ± 2.04) ( P  = 0.04). The number of oral ulcers and healing time of oral ulcers were significantly higher in RAS compared with BD ( P  = 0.018, P  = 0.001 respectively). CI score correlated with the number of oral ulcers in both BD and RAS ( P  = 0.000, P  = 0.002 respectively). CI score was '0' for inactive patients without oral ulcer in BD and RAS.
Conclusions:  The presented CI as an oral ulcer activity index seems to be a reliable and suitable tool for evaluating the clinical impact and disease-specific problems in BD and RAS.     

Congenital lobar emphysema —A report of 5 cases

Five infants with congenital lobar emphysema whose main symptoms included dyspnea, cyanosis and recurrent respiratory infections, are presented herein. The most reliable diagnostic tool was plain chest X-ray films with antero-posterior and lateral views, while radio-isotopic investigation of the lung perfusion state took second place in the diagnosis of this disease. The affected lobes were the left upper lobe in four patients and the right middle lobe in one. Lobectomy was performed with good results in 4 patients, however, 1 infant was lost following an emergency thoracotomy.     

Effect of a dilacerated root on stress distribution to the tooth and supporting tissues

The configuration of the root of a prospective abutment tooth has a significant influence on its potential load-bearing capacity. Dilaceration is an angulation in the root or crown. This abnormality may also affect the stability and longevity of an abutment. Finite element stress analysis was used to investigate the effect of a root dilaceration on stress distribution to the tooth and its supporting structures. A normal and a dilacerated single-rooted tooth under three loads (axial, distooblique, and mesio-oblique) were analyzed and compared. The results indicated that a dilaceration concentrates the stresses in the supporting structures and may be taken into consideration as a risk factor in abutment selection.     

Pleural fluid and serum procalcitonin as diagnostic tools in tuberculous pleurisy

BACKGROUND: Diagnosis of tuberculous pleuritis is difficult because of its nonspecific clinical presentation and decreased efficiency of traditional diagnostic methods. We investigated the use of procalcitonin (PCT) concentration in tuberculous pleuritis diagnosis. METHODS: A prospective clinical study was performed with two different patient groups. A total of 28 patients were included: 18 with tuberculosis and 10 with nontuberculous pleurisy. Serum and pleural fluid PCT concentrations were evaluated before treatment. RESULTS: Serum and pleural fluid PCT concentrations were statistically different between tuberculous and nontuberculous pleurisy groups (P = 0.012 and P = 0.004, respectively), even though they were not elevated in relation to the cut-off level of 0.5 ng/mL. A positive and significant correlation was detected between serum and pleural fluid PCT levels (r = 0.49, P = 0.008). Diagnostic specificity and sensitivity values for serum and pleural fluid PCT in discriminating tuberculous from nontuberculous pleurisy were 80% and 72.2%, and 90% and 66.7% at the 0.081 and 0.113 ng/mL cut-off values, respectively. CONCLUSION: Relative to the current cut-off level of 0.5 ng/mL, PCT concentration is not a useful parameter for the diagnosis of tuberculous pleurisy. Because there were PCT levels in patients with tuberculous pleurisy that were below the current cut-off level but were significantly different from those of the nontuberculous group, the use of PCT should be further investigated.     

Pilonidal sinus disease surgery in children: the first study to compare crystallized phenol application to primary excision and closure

Introduction

Pilonidal sinus (PS) is an infectious and inflammatory disease of sacrococcygeal region. Current methods include; surgical excision with/without suturing the defect, rhomboid excision and flap and chemical substance application. In this study, crystallized phenol application was compared to excision and primary closure.
