Some species of mesophilic bacteria in the genus Aeromonas were isolated from a snakehead (Channa argus) culture-pond in the Myung-Ji area, a freshwater culture-pond in Pukyung National University, and seawater near the sewage treatment plant in Kwang-An Beach in Pusan. They were identified by biological characteristics, and their susceptibility to ten antibiotics including ampicillin, cefoxitin, ceftazidime cephalothin, cefotiam, chloramphenicol, nalidixic acid, rifampin, cefoperazone-sulbactam, and imipenem, was also studied. Four species in the genus Aeromonas, A. veronii biovar sobria (27 strains), A. caviae (14 strains), A. trota (1 strain), and A. schubertii (1 strain) were identified. A. trota, an unrecorded species in Korea, is reported for the first time in this study. Three strains of A. veronii biovar sobria showed multiple resistance to three kinds of antibiotics and one strain to four drugs. All strains of A. caviae were resistant to more than three drugs and seven strains to four drugs. A. trota was resistant to cephalothin and rifampin, but A. schubertii showed multiple resistance to ampicillin, nalidixic acid, and rifampin.

A 52-year-old man with multiple myeloma developed cutaneous nodules while being treated with melphalan and prednisolone. A biopsy specimen showed dermal infiltration by well differentiated plasma cells similar to those found on bone marrow biopsy. The use of peroxidase anti-peroxidase to demonstrate the monoclonality or polyclonality of the cytomplasmic immunoglohulins in the tumor cells revealed a positivity for IgG and 1 chain (ie, monotypic staining). Ultrastructurally, each plasmacytoma cell contained varyting amounts of rough endoplasmic reticulum and Golgi-apparatus. The cutnneous nodules completely disappeared after radiotherapy

We herein report a case of palmar fibromatosis, who was 78-year-old male and had had multiple variable-sized subcutaneous hard nodules on the left palm for 2 months. Histopathologic findings of the lesion revealed that the nodules were highly cellular, containing numerous spindle shaped cells. Ultrastructurally, intracytoplasmic micrcfilaments were present, and the nuclei were extremely indented by one or more transverse folds. These findings suggested the cells were myofibroblasts.

Sixty amputees who had traumatic amputations due to industrial accidents were examined on their phantom limb and phantom pain phenomena and the following results were obtained. 1. Fifty-three (93%) of sixty amputees experienced phantom limb and twenty-four (40%) experienced phantom pain. The incidence of phantom pain in the lower limb amputation (59%) is greater than that of upper limb amputation (29%). 2. Amputees with asthenic body status gave higher incidence (56%) of phantom pain than those with muscular body status (20%). None of amputees with obese body status experienced phantom pain. 3. The sensation of strong current and cramping were most predominant sensations in the phantom pain. 4. Twenty-eight (93%) of thirty amputees had experienced painless phantom limb longer than four months. 5. Six (55%) of eleven upper limb amputees with phantom pain experienced pain sensation at the tips of fingers and nine (69%) of thirteen lower limb amputees with phantom pain experienced pain at the great toe. 6. Fifty-three (88%) of sixty amputees experienced telescoping of the lost limb and twenty-three (38%) of sixty amputees experienced jerking movement of the stump. 7. In fifty-four (90%) of sixty amputees, trigger zones triggering pain in the phantom limb were found in the healthy part of the body. 8. Twenty-two (40%) of fifty-five male amputees experienced burning sensation in the phantom limb associated with urination, defecation or ejaculation. 9. Cold temperature was predominant, aggrevating factor of the phantom pain. Fitting prosthesis and alcohol intake were predominant, relieving factor of the phantom pain.

Tibialis anterior muscle hernia is the most common hernia among lower extremity muscles. This condition can be diagnosed by physical examination and radiologic findings, especially by dynamic ultrasonography. There are surgical methods of treatment for muscle hernia, including direct repair, fasciotomy, fascial patch grafting using autologous fascia lata or synthetic mesh. We report a case of tibialis anterior muscle hernia treated with local periosteal rotational flap. Because there are several advantages to the local periosteal rotational flap, such as lack of donor site morbidity, lack of skin irritation, low cost, simplicity, and an easy approach, this technique could be an option for tibialis anterior muscle hernia.

Electrocorticograms were recorded in cases with cases with epilepsies following procainization and eletrocoagulation of limited areas of cerebral cortex. Procainizaion of preoccipital cortical area, Brodmann's area 19, causes suppression of epileptiform discharge in the rest or ipsilateral cerebral hemisphere, motor, sensory and temporal areas. Conversely no suppression of electrical activity was observed in preoccipital leads following procainization of motor, senory or temporal areas. Electrocoagulation of preoccipital area also produced a regression of the abnormal cortical activities in the motor, sensory and temporal areas, which was the phenomenon identical with that following procainization of preoccipital area, and lasted weeks and months along with clinical improvement in symptomatology of epilepsy. Fifty-one cases of intractable epilepsy were treated surgically by the coagulation of preoccipital areas which were exposed through skull trephine hole with perforator in D'Errico trephine. It was noteworthty to emphasize that progressive normalization of electroencephalographic records of patients was obtained in months or years after the preoccipital coagulation. The surgical treatment of epilepsy in fifty-one cases was associated with freedom from seizures in three cases and clinical improvement in thirty-none cases. The purpose of surgical intervention upon preoccipital area was mainly based on blocking and suppressing the abnormal excessive neuronal discharge passing or spreading through the preoccipital cortical area over the rest of ipsilateral cerebral hemisphere.
