BACKGROUND: Diabetes mellitus is a common condition, and the majority of patients have one or more cutaneous complications. Among them, xerosis is well known to be closely related to diabetics. The xerosis is inversely reflected upon skin surface hydration, the state of which can be exactly assessed with various investigating instruments, such as a hydrometer and corneometer. OBJECTIVE: Our purpose was to compare the hydration state of diabetics with normal persons by the use of a corneometer and hydrometer. METHODS: A total of 267 diabetics were asked whether they felt xerosis or pruritus. In a subgroup of 31 patients, the water content was evaluated and compared by the parameters of diabetic severity. Forty-one non-diabetics were selected for the normal control.

PURPOSE: Serum levels of G-CSF and GM-CSF were measured and CFU-GM assay using G- CSF, GM-CSF and SCF was conducted to evaluate the influence of hematopoietic growth factor on the precursor cells of cyclic neutropenia. METHODS: A 7-year-old male with cyclic neutropenia was studied. Marrow mononuclear cells were isolated at neutrophil nadir and recovery and cultured in methylcellulose media with or without G-CSF, GM- CSF and SCF. CD34 positive cells were evaluated using flow cytometry. Serum levels of G-CSF and GM-CSF were measured by ELISA. RESULTS: The Numbers of CFU-GM without growth factors were 50 at neutrophil nadir and 33 at the recovery phase in the patient and show increased colony forming capacity. CD34 positive cells were 9.32% at nadir and 14.17% at recovery. Increasement of CFU-GM with G-CSF at nadir and recovery were 46% and 118% and those with GM-CSF were 70% and 78% respectively, compared with 54.4% and 78.2% in control groups. In contrast, the presence of SCF did not enhance CFU-GM number in the patient, but in the control group, increasement with SCF was 28.9 %. There an was inverse relationship between serum G-CSF levels and peripheral neutrophil count whereas those of GM-CSF were constant. CONCLUSION: Serum G-CSF level showed inverse relationship with neutrophil counts. The response of progenitor cells to G-CSF and GM-CSF was not impaired. The presence of SCF did not enhance CFU-GM number in the patient. This result suggests that the abnormality in hematopoiesis in cyclic neutropenia may involve more immature progenitor cells responsive to SCF.

BACKGROUND: Motor conduction slowing in diabetic distal symmetrical polyneuropathy (DSP) generally exceeds that in distal axonal polyneuropathy. Additional mechanisms secondary to axonal injury may contribute towards this slowing. However, clinical and pathophysiological significances of motor conduction slowing have been rarely discussed. The purpose of this study is to evaluate the clinical and pathophysiological significance of conduction slowing in DSP. METHODS: We analyzed motor conduction studies of 39 patients with symptomatic painful DSP and 24 patients with asymptomatic painless DSP. Motor conduction studies of 39 patients with amyotrophic lateral sclerosis (ALS) were used as controls for the amplitude-dependent slowing of conduction. Percentages of normal limits were calculated for the compound muscle action potential amplitude (CMAP), distal motor latency (DL), and conduction velocity (CV), and converted to a square root (SQRT) form. The changes of SQRT-DL or SQRT-CV according to SQRT-CMAP changes were plotted and analyzed. RESULTS: Regression analysis showed that DL and CV were amplitude-dependent in both painless DSP and ALS. The changes of DL and CV in painful DSP did not show amplitude-dependency except DL in the lower extremities. CONCLUSIONS: This data supports the hypothesis that the mechanism of slowing is similar in both painless DSP and ALS and results from the loss of large, fast-conducting fibers. Lack of amplitude-dependency of conduction slowing in painful DSP may reflect the combined axonal and demyelinating changes, possibly due to inflammation.

Gastric lymphoepithelioma-like carcinoma is a rare carcinoma among gastric malignant tumor but has a good prognosis. The carcinoma has histologic feature characterized by small nest of cancer cells mixed with lymphoid stroma. We report a case with lymphoepithelioma-like carcinoma of stomach initially presenting as panperitonitis because of spontaneous tumor perforation. A 56-year-old man visited our emergency room because of epigastric pain. A preoperative abdominal CT scan showed a massive pneumoperitoneum in the upper abdomen, and the presence of gastric cancer in the lesser curvature of the stomach. An emergent laparotomy was performed followed by radical subtotal gastrectomy. Pathologic examination revealed that the tumor was a lymphoepithelioma-like gastric carcinoma.

Radiofrequency ablation (RFA) is a popular technique and shows excellent local tumor control and acceptable morbidity. Although RFA is considered much safer than surgical treatment, it is not a complication-free procedure. The most common complications of percutaneous RFA areabdominal hemorrhage, abdominal infection (abscess), biliary tract damage, and ground-pad burns. Laparoscopic RFA (LRFA) is a safe, feasible treatment modality to achieve tumor destruction. LRFA has proven superior to the percutaneous approach for lesions that are difficult or impossible to treat percutaneously. Needle-track implantationafter LRFA is a rare complication in HCCs. We report a case of needle-tract implantation of HCC found in the chest wall, ribs,and diaphragm 11 months after LRFA in a 49-year-old man. Although treatment for needle-track implantation is not well established, the metastatic mass was surgically removed.

The occurrence of a trigeminal neuropathy associated with connective tissue disease is rare. Trigeminal neuropathy in connective tissue disease is predominantly sensory and it is characterized by numbness, hypesthesia, slurred speech, and touch pain. Although the pathogenesis of trigeminal neuropathy associated with connective tissue disease remains obscure, the main pathologic findings are vasculitis and neuritis. A case of trigeminal neuropathy associated with mixed connective tissue disease is described, and the incidence, symptoms, pathophysiology, treatment of the disease is discussed.

BACKGROUND: Most febrile neutropenic patients are treated in an aggressive manner. However, identification of low-risk patients may enable clinicians to administer risk-based treatment. The object of this study is to certify the factors associated with increased risk at the time of visiting the emergency department. METHODS: This is a retrospective study. We reviewed the medical records of 101 febrile neutropenic patients who had visited the emergency department of Seoul National University Hospital from January 1998 to August 1999. We assumed 22 risk prediction factors that could be assessed at admission to the emergency department and 5 factors that could be assessed during treatment course. To find independent risk-prediction factors, we analyzed these factors respectively by using multiple regression analysis. RESULTS: Tachycardia(aOR=136.5), altered mentality(aOR=28.8), decreased renal function(aOR=20.1), and significant comorbidity(aOR=17.2) are the independent factors associated with higher mortality. Altered mentality(aOR=31.6) and decreased renal function(CCr<75ml/min, aOR=5.4) are those associated with a higher incidence of septic shock. Independent factors associated with persistent(more than 3 days) fever are the early(within 10 days) onset of fever after last chemotherapy(aOR=8.8) and the existence of new pulmonary infiltrates on a simple chest X-ray(aOR=4.3). CONCLUSION: The stability of vital signs, the change of mentality, the renal function, the existence of significant comorbidity, the existence of new pulmonary infiltrates, and the rate of neutropenia are clinically useful risk-predication factors in febrile neutropenia at the time of visiting the emergency department.

BACKGROUND: Contact dermatitis is frequently caused by cosmetics. Detection of causative allergens is important in prevention and treatment of cosmetic contact dermatitis. Patch test has been accepted as the only reliable diagnostic method to detect allergens. OBJECTIVE: The objectives of this study were to clarify evoluting trends of positive patch tests and to compare the positive frequencies of various allergens between different time sequences. MATERIALS AND METHODS: We reviewed patch test results of the 806 cosmetic contact dermatitis patients, who had visited our clinic from 1982 to 1997. We divided the patients into three groups as follows: I group:1982-1987, II group:1988-1992, III group:1993-1997 and compared the test results. The patch tests were performed with standard batteries, cosmetic-related allergens and the patients's own cosmetics. RESULTS: The results of the studies were summarized as follows; 1. Trends of increasing positivity in cosmetic-induced dermatitis was noted in a chronologic point of view. Among the patients, an increased proportion of males was notable. 2. In age distribution, a decreasing proportion of patients at the third & the fourth decades was observed. Contrary to this, the proportion of patients over the fifth decades was increased. 3. Among standard allergens, nickel sulphate showed the highest positive rate in all defined triple periods, whereas positive rates of neomycin sulphate & balsam of Peru were diminishing sequentially. Among fragrance allergens, cinnamic alcohol & cinnamic aldehyde revealed the highest positive rates. 4. In as is test, skin care products showed the highest positive rate, followed by toiletries and makeup products. Increasing positive rates of the toiletry products were observed in order of time. In fragrance products, positive rates reached their peak in the second period and declined in the third period. CONCLUSION: This study showed that perfume components were the most frequent allergens in cosmetics followed by preservative agents. Our study showed that comestic allergies in men seems to have increased.

PURPOSE: This study assesses the usefulness of alkaline phosphatase (ALP) in predicting the radiologic osteopenia and rickets for very low birth weight infants (VLBWI) below 1,500 g of birth weight. METHODS: Medical records of 258 VLBWI who were admitted at NICU between January 2009 and December 2011 were reviewed retrospectively. ALP max was defined by maximum level of ALP during admission. Subjects were divided into two groups: the study (n=112, ALP max > or =450 IU/L) and the control group (n=146, ALP max <450 IU/L). The two groups were compared based on the demographic and perinatal risk factors, clinical parameters, and morbidity. Also compared between the groups were: the level of ALP max, total and ionized calcium, inorganic phosphorus, and radiologic finding. To assess the usefulness of ALP in predicting the radiologic osteopenia and rickets, the sensitivity, specificity, and the positive (PPV) and negative predictive values (NPV) according to ALP max level were examined. A receiver operator characteristic (ROC) curve was constructed to determine the optimal cut-off value of ALP for the radiologic diagnosis. RESULTS: The study group was more immature and smaller, and had more perinatal risk factors with higher morbidity. The sensitivity and specificity for the radiologic finding on the basis of ALP max 450 IU/L were 68.8% and 64.9%, PPV 39.3%, and NPV 86.3% with a significance (P<0.001). In ROC curve, we observed the appropriate cut-off value to be 459.5 IU/L (P<0.001). CONCLUSION: The baseline of ALP max 450 IU/L was useful in predicting the radiologic osteopenia and rickets in VLBWI.
