Subcutaneous fat necrosis of the newborn is an uncommon disorder which is characterized by multiple erythematous subcutaneous nodules and plaques appearing in the first week to a month of life. The chief precipitating factors presumably concerned in this disease are obstetric trauma, anoxia and cold exposure. We observed a case of subcutaneous fat necrosis of the newborn in which intrauterine asphyxia and preeclampsia had occured.

Candida infections after total knee replacement are extremely rare and show no specific symptoms and signs, thus make it difficult to diagnose. It is desirable to perform fungi culture from the beginning in case of persistent swelling and burning sensation in patients after total knee replacement with risk factors such as intraarticular steroid injection, intravenous drug abuse, immunosuppressive therapy, malignant hematologic tumor, etc. Positive culture of candida should never be considered as contaminated study, and be treated immediately. We report a case of candida infection after total knee arthroplasty, which was treated with staged reimplantation.

Twenty-eight cases of initial psoriasis were studied with histochemical methods in an attempt to obtain changes of acid mucopolysaccharides and mast cells. Early psoriatic lesions (pin head sized) and clinically uninvolved skin at distances of 2-4cm from the psoriatic lesions were excised respectively. The results are as follows; 1. Dermal changes were more prominent than the epidermal changes in almost all specimens in early psoriatic lesions. The main features of the dermal changes were perivascular inflammatory infiltrate which were consisted mainly of lymphoid cells. 2. Inflammatory infiltrate in the region of epidermal a.lteration and papillary edema is par ticulary striking. R. Among the 26 cases, the amount of acid mucopalysaccharides of initial lesion was lesser in 14 cases, greater in 4 cases and same in 8 cases as compared with clinically normal skin. 4. The number of mast cells of initial psoriatic lesion as compared with clinically normal skin was increased(p<0. 01).

ErbB3/HER3 is a cell surface receptor which belongs to the ErbB/HER subfamily of receptor protein tyrosine kinases. When expressed in NIH/3T3 cells, ErbB3 can form heterodimeric coreceptor with endogenous ErbB2. Among known intracellular effectors of the ErbB2/ErbB3 are mitogen-activated protein kinase (MAPK) and phosphoinositide (PI) 3-kinase. In the present study, we studied relative contributions of above two distinct signaling pathways to the heregulin-induced mitogenic response via activated ErbB3. For this, clonal NIH-3T3 cell lines expressing wild-type ErbB3 and ErbB3 mutants were stimulated with heregulin beta1. While cyclin D1 level was markedly high and further increased by treatment of heregulin in cells expressing wild-type ErbB3, the elimination of either Shc binding or PI 3-kinase binding lowered both levels. This result was supported by the reduction of cyclin D1 expression by preteatment with MAPK kinase inhibitor or PI 3-kinase inhibitor before stimulation with heregulin. In accordance with the cyclin D1 expression, elimination of either Shc binding or PI 3-kinase binding reduced the heregulin-induced DNA synthesis and cell growth rate. Our results obtained by the comparison of wild-type and ErbB3 mutants indicate that the full induction of the cell cycle progression through G1/S phase by ErbB3 activation is dependent on both Shc/MAPK and PI 3-kinase signal transduction pathways.

BACKGROUND: This study aimed to compare analgesic efficacy and occurance of motor block and other side effects of a 48 hr postoperative continuous epidural infusion of 0.125% bupivacaine or ropivacaine with morphine. METHODS: Forty patients undergoing a Cesarean section were allocated randomly into two groups. Both groups received an epidural injection of 2.0% lidocaine 18 20 ml and 0.5% bupivacaine 2 5 ml with fentanyl 50microgram 20 minutes before surgical incision and received 2 mg of epidural morphine by bolus 40 minutes after surgical incision. For post-operative pain control, a continuous epidural infusion was started using a two day infusor containing 6 mg of morphine in 100 ml of 0.125% bupivacaine (Group 1, n = 20) or 100 ml of 0.125% ropivacaine (Group 2, n = 20). Visual analog scale (VAS) for pain during rest and movement, sensory change and motor blockade were assessed for 48 hrs. after surgery. RESULTS: There were no significant differences in VAS for pain during rest and movement. The incidences of side effect were similar in both groups. CONCLUSIONS: Using 0.125% bupivacaine with morphine via the epidural route provided similar pain relief and side effects as 0.125% ropivacaine with morphine.

Background/Aims: The aim of the study was to investigate the current nationwide burden of nosocomial exposure to tuberculosis (TB) using national health insurance claims data. Methods: All patients who had claims for drug susceptibility testing for TB from 2012 to 2016, which indicated culture-proven TB, were included. The first day of the infectious period was defined as 3 months before a doctor’s suspicion of TB in patients with respiratory symptoms and 1 month before in patients without symptoms. The last day of the infectious period was defined as one day before the prescription of anti-TB medications. Patients hospitalized during infectious periods were investigated and their hospitalization days were calculated. Records of medical procedures which increased the risk of nosocomial transmission by generating aerosols were also investigated. Results: A total of 7,186 cases with 94,636 person-days of hospitalization with unrecognized active TB were found. Patients above 60 years of age accounted for 63.99% of the total number and 69.70% of the total duration of hospitalization. TB patients in the older age group showed a trend toward higher risks for hospitalization with unrecognized active TB. Patients in their 80s showed the highest risk (12.65%). Bronchoscopy (28.86%), nebulizer therapy (28.48%), and endotracheal intubation (13.02%) were common procedures performed in these patients during hospitalization. Conclusions The burden of nosocomial exposure to TB in South Korea is still substantial. Hospitalization with unrecognized active TB, especially among the elderly TB patients could be a serious public health issue in South Korea.

Delayed-onset continuous bruxism due to brain stem infarction has not yet been reported. A 49-year old man presented with quadriplegia and ophthalmoplegia. Brain MRI showed acute infarction in the bilateral midbrain, right thalamus and the superior cerebellum. One month later, the patient developed bruxism which persisted during sleep. A palatal myoclonus was not observed. Follow up MRI taken 4 months later showed bilateral olivary hypertrophy. We suggest that the patient's bruxism may be related to the olivary hypertrophy. The bruxism generator may be located in the pontine-reticular-formation (PRF). Bilateral large midbrain lesions interrupting the cortical inhibition may have produced bilateral olivary hypertrophy, which could stimulate the PRF, producing continuous bruxism.
