T/NK-cell neoplasms incorporated in this study were generally FDG-avid except for cutaneous lesions and bone marrow involvement.

We present two patients with frontal pure agraphia more impaired for either kanji or kana (two separate writing systems for the Japanese language). The lesion of patient 1 (preferentially disturbed for kanji) was restricted to the foot of the middle frontal gyrus and the adjacent anterior precentral gyrus, whereas the lesion of patient 2 (preferentially disturbed for kana) included the posterior two thirds of the middle frontal gyrus. Both patients made agraphic errors (impaired recall) for kanji and agraphic or paragraphic errors (changing into other symbols) for kana. The double dissociation and the difference in types of errors between kanji writing and kana writing suggests that there are two pathways involved in writing, i.e., a morphologic route and a phonologic route. We concluded that damage to the morphologic route may yield agraphia for kanji and that damage to the phonologic route may yield agraphia for kana.

High friction suture techniques may cause more adhesion formation than the lower friction suture techniques under passive postoperative therapy.

The effect of knot location, suture material, and suture size on gliding resistance between the pulley and flexor tendon was investigated in a canine model. Different suture materials [monofilament nylon (Ethilon), braided polyester suture coated with silicone (Ticron) and uncoated braided polyester suture (Mersilene)] and suture sizes (4-0, 5-0) were tested. A knot was made on either the volar surface, on one lateral side, or on both lateral sides of canine hind-paw tendons, and gliding resistance was measured. In addition, the frictional coefficient between three suture materials (4-0 nylon, 4-0 Ticron, 4-0 Mersilene) and a nylon rod were measured. The gliding resistance of the tendon with knots on both sides was highest, while tendons with one lateral knot had the lowest resistance (p < 0.01). The gliding resistance of 4-0 suture size was higher than that of 5-0 size (p < 0.0001). The coefficient of friction of nylon was lower than that of braided polyester suture (Ticron or Mersilene) (p < 0.001). The placement of knots and choice of suture material affect gliding resistance after tendon repair, and may, therefore, have an effect on the result of tendon repair.
