Influence of age of onset on clinical features in obsessive-compulsive disorder

We compared early-onset and late-onset obsessive-compulsive disorder (OCD) patients in terms of demographic and clinical features. One hundred sixteen outpatients whose primary diagnosis was OCD according to DSM-IV diagnostic criteria were recruited. Early-onset (n=50) and late-onset (n=66) OCD groups were compared with respect to demographic variables and scores obtained on various scales. A male gender predominance was found in early-onset OCD group. Symmetry/exactness obsessions, religious obsessions, hoarding/saving obsessions, and hoarding/collecting compulsions also were significantly more frequent in the early-onset group than in the late-onset group. The results may suggest a phenotypic difference between the two groups. Further studies are needed to investigate the differences between early-onset and late-onset OCD groups to examine the hypothesis that early-onset OCD is a distinct subtype of the disorder.     

Diaphragmatic and crural FDG uptake in hyperventilating patients: a rare pattern important to recognize

The authors describe various patterns of F-18 fluorodeoxyglucose (FDG) accumulation in the diaphragm and crura. They present 6 patients in whom incidental diaphragmatic and crural uptake of FDG was observed during positron emission tomography (PET). Hyperventilation is thought to be the potential underlying mechanism of this condition.     

Successful ivermectin treatment of hepatic strongyloidiasis presenting with severe eosinophilia

A 49-year-old, previously healthy nurse presented with hepatic lesions and severe peripheral eosinophilia due to strongyloidiasis. Imaging studies of the abdomen showed predominantly peripheral, confluent hepatic lesions. The hepatic lesions and eosinophilia did not show any improvement with albendazole, but completely resolved with ivermectin treatment. Our findings suggest that Strongyloides stercoralis can present with isolated focal hepatic lesions and severe eosinophilia, and resolves with ivermectin treatment.     

Transscleral fixation of foldable intraocular lenses

PURPOSE: To report the results of transscleral implantation of foldable intraocular lenses (IOLs). SETTING: Department of Ophthalmology Dokuz Eylül University School of Medicine, Izmir, Turkey. METHODS: Twenty eyes of 20 patients had transscleral fixation of a foldable IOL combined with conventional 3-port pars plana vitrectomy or anterior vitrectomy. Twelve eyes had lens luxation, 8 traumatic and 4 idiopathic. Six eyes were aphakic, 3 after extracapsular cataract extraction and 3 as a result of complicated phacoemulsification. One patient with a mature cataract and pseudoexfoliation had a wide zonular dialysis during phacoemulsification. One patient had an opacified hydrophilic acrylic IOL. RESULTS: The mean age of the patients was 52.9 years (range 17 to 80 years). The mean preoperative best corrected visual acuity (BCVA) was 20/63 (range counting fingers to 20/25). The mean preoperative refraction was +10.8 diopters (D) (range +10 to +13 D) and the mean preoperative astigmatism, 1.8 D (range 1.0 to 5.5 D). Sixteen IOLs were hydrophobic acrylic, 14 of which were 3-piece AcrySof MA60BM (Alcon) and 2 of which were Sensar AR40 (Allergan). Four IOLs, all VisaAcryl(Staar), were hydrophilic acrylic. The mean power of the IOLs was +22.0 D (range 19.0 to 26.0 D). The mean follow-up was 12 months (range 1 to 18 months). The postoperative BCVA ranged between 20/100 and 20/20, and the mean postoperative astigmatism was 1.1 D (range 0.5 to 4.0 D) at the last follow-up visit. The difference was statistically significant (P<.05). Suture exposure and cystoid macular edema were the only complications, each occurring in 2 eyes. CONCLUSION: Transscleral fixation of foldable IOLs takes less time and results in fewer complications and better visual outcomes.     

Prolonged hyperglycemia in the early subacute period after cerebral infarction: effects on short term prognosis

Although the adverse effect of admission hyperglycemia in cerebral infarction on prognosis is well known, studies generally have not questioned the effect of hyperglycemia in the early subacute period on prognosis after a stroke. Forty-six patients with acute ischemic stroke were seperated into 3 groups: Group 1) Known diabetes or admission blood glucose (ABG) > or = 140 mg/dl and HbA1c > or = 8,0%); Group 2) ABG > or = 140 mg/dl and HbA1c < 8,0%; and Group 3) ABG < 140 mg/dl and HbA1c < 8,0%. Blood glucose was followed-up 4 times a day for 10 days after the stroke and the mean of these measurements was calculated as the mean of glycemic regulation (MGR). Neurological evaluation was done at presentation and on day 10 and 30 with the National Institute of Health (NIH) scale. Oedema, lesion size and presence of hemorrhagic transformation were evaluated using CT. The MGR was significantly higher in group 1 compared to the other two groups (p < 0,001 and p < 0,01) and in group 2 compared to group 3 (p < 0,001). Patients with clinical worsening had a significantly higher MGR (p < 0,05). Patients with marked cerebral edema had a significantly higher MGR (p < 0,01) compared to patients with lesser edema. No correlation was found between MGR and lesion size or hemorrhagic transformation. Our results show that hyperglycemia in the early subacute period after cerebral infarction is associated with more pronounced cerebral edema and has an adverse effect on short term prognosis. We suggest that studies investigating the effect of insulin infusion on stroke prognosis should also consider infusions for a longer period than 24 hours.
