Essential tremor (ET) is classified as a pure motor system disease. It has been previously reported that impairments in cognitive functions can be associated with ET. The authors assessed cognitive functions in a relatively young patient group with ET and comparison subjects. Correlations between tremor severity and regional cerebral blood flow (rCBF) and neuropsychological test performances of ET patients and comparison subjects were investigated. Sixteen patients with ET and 16 comparison subjects were assessed by a comprehensive neuropsychological test battery designed to assess global attention, language, memory, visuospatial functions, and executive functions. In 11 of 16 patients and in nine of 16 comparison subjects, rCBF was measured by technetium-99m-hexamethyl propylene amine oxime single photon emission computed tomography (technetium-99m-HMPAO SPECT). The tremor severity was quantified using the Clinical Rating Scale for Tremor (CRST). Findings revealed that ET patients differed significantly from comparison subjects on tests assessing visuospatial functions and verbal memory, whereas differences in other tests did not reach statistical significance. There was no significant difference between the rCBF of ET patients and comparison subjects. There were statistically significant inverse correlations between tremor severity and executive functions. Tremor severity was inversely correlated with bilateral frontal blood flow by technetium-99m-HMPAO SPECT. Conclusions suggest that the subclinical cognitive deficits characterized by visuospatial and verbal memory impairments and executive dysfunction may be a clinical feature of ET, and the cerebello-thalamo-frontal network may play a role in the pathophysiology of this disorder.

Recent supermicrosurgical techniques have developed the possibility for vascular anastomosis of smaller vessels and it is now safe and sound to perform precise anastomoses between lymphatics and venules. Reported here is the 2 years experience on supermicrosurgical lymphaticovenular anastomosis and/or lymphaticovenous implantation combined with a nonoperative physical therapy for treatment of lower extremity lymphedema. Microlymphatic surgery was performed in 42 patients with unilateral lower extremity lymphedema. Thirty patients were women and 12 were men with a mean age of 34. Lymphaticovenular anastomoses were performed in 37 patients with an average of 2.5 anastomoses per patient, and lymphaticovenous implantations were made in 36 patients with an average of 2.4 implantations per patient. The lymphatics that were larger than 0.3 mm were anastomosed to venules with supermicrosurgical technique. Lymphaticovenous implantation technique was used for thinner lymphatics in a particular incision. Postoperatively, 18 patients used continuous compressive garments, 9 patients used garments but discontinued after 6 months, and no compression was used in 9 patients. The results of surgery were assessed both clinically with volume measurements and by lymphoscintigraphy and were classified as good, moderate, or ineffective. The mean decrease in the volume of the edema was 59.3% at an average follow-up of 11.8 months. Six outcomes were classified as ineffective, eight outcomes as moderate, and 28 outcomes as good. Supermicrosurgical lymphaticovenular anastomosis and/or lymphaticovenous implantation seems to be highly beneficial, especially in the early stages of peripheral lymphedema and may be offered as the treatment of choice in selected patients.

Although some authors previously stated that microlymphatic surgery does not have application to primary lymphedema, opposite views are reported based on the observations that the lymphatics were not hypoplastic in majority of these patients and microlymphatic surgery yielded significant improvement. The aim of this study was to compare the intraoperative findings and outcomes of primary and secondary lower-extremity lymphedema cases treated with lymphaticovenous shunts. Between December 2006 and April 2009, microlymphatic surgery was performed in 80 lower extremities with primary and 21 with secondary lymphedema. These two groups of extremities are compared according to the morphology of the lymphatic vessels and possibility of precise anastomoses, their response to the treatment, and final outcomes based on volumetric measurements during the follow-up period. The morphology of the lymphatics in secondary lymphedema was more consistent, and at least one collector larger than 0.3 mm was available for anastomosis in 20 of 21 extremities. In the primary lymphedema group, the lymphatics were smaller than 0.3 mm in 13 of 80 extremities. It was, therefore, possible to perform supermicrosurgical lymphaticovenous anastomosis in 84% of extremities with primary lymphedema and 95% of extremities with secondary lymphedema. Reduction of the edema occurred earlier in the secondary lymphedema group, but the mean reduction in the edema volume was comparable between the two groups. Microlymphatic surgery, although more effective and offered as the treatment of choice for secondary lymphedema, would also be a valuable and relevant treatment of primary lymphedema.

This study found that the parameters useful for distinguishing HUPE and HSPE included CTPA obstruction score, RV and SVC diameters, RV/LV short-axis ratio, interventricular septum shape, and reflux into the IVC. RV dilatation may be a significant predictor for mortality.

The aim of this study was to search for any relations between the neutrophil-to-lymphocyte ratio (NLR) and the development of osteomyelitis and the need for amputation in patients with diabetic foot infection (DFI). All data included DFI patients who were hospitalized in our Infectious Diseases Clinic between 2012 and 2015 and who were classified according to International Classification Disease Code System. 75 patients were analyzed in the study. The DFI patients were stratified into 3 groups of whom had amputation procedure, whom had only debridement/drainage procedure and whom had any surgery procedure. Sidac post hoc analysis was used to perform the effects of NLR, C-reactive protein, erythrocyte sedimentation rate and glycosylated hemoglobin on the surgery procedure status. The DFI patients were also stratified into two another separate group for another analysis to search for the effect of NLR values on the development of osteomyelitis. The mean value of NLR in the amputated patients’ group (15.7±10.3 was significantly higher than those with debridement procedure (9.9±5.6) and those without any surgery (6.0±2.8) (P=0.001). NLR values were also found significantly higher in patients with osteomyelitis in the second analysis (P=0.004). In this study, the NLR was found to have a predictive value on the development of osteomyelitis and on the progression to amputation in patients with DFI.
