Cutis verticis gyrata(CVG) is a descriptive term for a condition of the scalp in which deep furrows and convolutions are seen that resemble the outer surface of the cerebrum. The possible etiologies may be categorized as primary essential, primary nonessential, and secondary cutis verticis gyrata. This is based on history, physical examination, and histologic criteria with or without laboratory examinations. Herein we reported a case of primary essential cutis verticis gyrata with no associated disorders.

BACKGROUND: Flood is the most common natural disaster in our country. Lots of victims occurred during the period of flood in the northern territory of Kyoungkido on August 5, 1998. We tried to describe the characteristics of the flood-related injury and illness, management and medical requirements. METHODS: We interviewed the patients admitted to 8 hospitals in Ujungbu and reviewed medical records from aug 5 to Aug 14, 1998. RESULTS: There were total 102 patients, male were 52%and women were 48% Most of patients were between 30's and 60's. Most of them were minor, and less than 3%of them needed critical care. The diagnosis were laceration(39.2%, contusion(22.5%, fracture(13.7%, infectious disease(7.8%, ligament rupture(7.8%, aggravation of chronic illness(5.9%, dermatitis(2.0% and traumatic hyphema(1.0%. The laceration occurred in the foot(37.9%, lower leg(27.0%, thigh(16.2%, hand(10.8% and head(8.1%. The location of ligament injury were achilless tendon(62.5%, hand(25% and knee(12.5%. The 67.5%of flood-related laceration patients progressed cellulitis, especially in sutured wound and a typical tetanic patient was developed. Of hospitalized patients, 2 patients showed evidence of post-traumatic stress disorder(PTSD). CONCLUSION: During flood, civils have better to be educated about prevention of injury, such as wearing of shoes and clothes. Although laceration was minor, lacerated wounds should be thoroughly irrigated, debrided the margin and considered delayed closure, tetanus immunization. Reportedly, there is an increased prevalance of PTSD and depression after disasters. Therefore mental health care will be required in the future.

Pulmonary siderosis is one kind of pneumoconiosis caused by the long term inhalation of iron dust. Iron is deposited in the lungs, usually in the form of iron oxides. Iron oxides are relatively inert particles with a minimal fibrotic response. It occurs in a number of occupations including welding, steel rolling and grinding, casting, iron ore mining and oxyacetylene cutters. We have experienced the first case of pulmonary siderosis in Korea. A 42-year-old woman who had engaged in a metalware manufacturing factory as a manager for 7 years was admitted because of dyspnea on exertion. A pulmonary function test disclosed a mildly obstructive ventilatory defect. Open lung biosy revealed deposition of iron-laden macrophages in most alveolar spaces by which confirmed the diagnosis of pulmonary siderosis. We report a case of pulmonary siderosis with a review of the literature.

Basal cell carcinomas(BCCs) are the most common skin cancers in Korea and a proportion of BCCs contain pigment. Pigmented basal cell carcinomas(PBCCs) are included in the differential diagnosis of invasive melanoma and other benign pigmented skin lesions(PSLs) because of their growth patterns and asymmetry of pigmentation. Epiluminescence microscopy(ELM) describes the non-invasive in vivo examination of skin lesions with a microscope using incident light delivered from an acute angle and oil immersion. Many studies have shown that epiluminescence microscopy can improve the diagnostic accuracy of PSLs. Menzies et al analyzed the morphologic features of a large set of 142 pigmented BCCs and produced a simple ELM method for diagnosis that would allow differentiation from melanomas and benign pigmented lesions. We observed morphologic features of two PSLs with a handheld 10 epiluminescence microscopy (Episcope, Welch Allyn Inc, Skaneateles Falls, NY). After the ELM examination, two PSLs were excised and processed for histopathology. The ELM findings and histopathologic diagnosis were compared for each lesion. ELM permits the recognition of two PBCCs and the fact that it is a non-invasive in vivo method makes it even more attractive as a diagnostic tool in clinical practice.

PURPOSE: Patent ductus arteriosus, derived left to right shunt flows, elevate the pulmonary artery pressure in infants and children and may alter right ventricular afterload thereby right ventricular function. Therefore, we examined the effects of patent ductus arteriosus on the right ventricular systolic time interval in premature infants by non-invasive Doppler echocardiography. METHODS: Tweleve premature infants with patent ductus arteriosus were studied by M-mode and Doppler echocardiography before and after treatment with mefenamic acid. Heart rate (HR), ratio of left atrium/aorta (LA/AO), right ventricular preejection period (RVPEP), right ventricular ejection time (RVET) and right ventricular systolic time interval (RVSTI : ratio of RVPEP/RVET), both corrected or uncorrected for heart rate were measured. RESULTS: After mefenamic acid treatment, in infants showing clinical response, right ventricular preejection period (RVPEP) and right ventricular systolic time intetrval (RVSTI), both corrected or uncorrected for heart rate, decreased significantly following ductal closure (RVPEP : 70.3msecc +/- 14.5 vs 54.3msec +/- 10.9, P<0.01, RVPEPc : 129.2msec +/- 13.5 vs 111.7msec +/- 8.4, P<0.01, RVSTI : 0.38 +/- 0.09 vs 0.28 +/- 0.05, P<0.05, RVSTIc : 0.31 +/- 0.04 vs 0.27 +/- 0.03, P<0.01). CONCLUSION: Premature infants with patent ductus arteriosus exhibit echocardiographic evidence of increased RVSTI as a result of increased right ventricular afterload. This results suggest that we have to make every effort to prevent the ductal reopening or early closure of ductus arteriosus in premature infants.

Phenobarbital is a long-acting barbiturate causing generalized depression of neuronal activity in the brain. Its effect is primarily achieved through enhanced GABA-mediated synaptic inhibition. Its use as an antiepileptic agent was first described in 1912. Before the introduction of phenytoin, phenobarbital is used as sedative-hypnotics. It is used for the treatment of epilepsy and status epilepticus. All barbiturates, including phenobarbital, have a high potential far abuse. They were frequently used for suicide attempts in the past, but they have in large part been replaced by benzodiazepines. the onset of symptoms depends on the drug and the route of administration. Mild to moderate barbiturate intoxication resembles ethanol inebriation with slurred speech, ataxia, and lethargy. Severe acute barbiturate intoxication is life threatening. Early deaths are generally cardiovascular-related. Hypotension, shock, pulmonary edema, and cardiac arrest that occurs with large doses are caused by depression of central sympathetic tone and as well as by direct depression of cardiac contractility. The potentially fatal oral dose of phenobarbital is 6-l0g. We describe an 23-year-old woman with pulmonary edema and cardiac arrest after ingestion of 18 grams of phenobarbital. She was completely recovered by successful cardiopulmonary resuscitation and hemoperfusion. We report a case with literature review.

Isoniazid(Isonicotinic acid hydrazide) is an antimicrobial drug used since 1952 as a fast line agent for the prophylaxis and treatment of tuberculosis. Isoniazid is well known for problems in population having a high prevalence of isoniazid use for prophylaxis or treatment of tuberculosis. But intentional or accidental isoniazid overdose is uncommon. The ingestion of toxic amounts of isoniazid causes recurrent seizures, profound metabolic acidosis, coma and even death. In adults, toxicity can occur with the acute ingestion of as little as 1.5g of isoniazid. Doses larder than 30mg per kg often produce seizures. When ingested in amounts of 80-150mg per kg or more, isoniazid can be rapid fatal. 40-year-old woman having previous pulmonary tuberculosis ingested 7 gram of isoniazid(140mg/kg) to attempt suicide approximately 30 minutes prior to visit to our emergency medical center. She had recurrent generalized tonicclonic seizures and metabolic acidosis. We report one patient treated with pyridoxine, which was equivalent to the amount of isoniazid ingested and administered as a intravenous dose and oral dose.

Overcrowding of emergency department is a serious and growing problem at St. Mary's Hospital. This has motivated the development of short-stay unit(SSU) as an alternative ward to routine hospital admission and ED discharge. In our hospital a SSU begun to admit patients in January 6, 1997. the SSU received 247 patients from the ED during the eight month interval(January 6, 1997 to August 31, 1997). To examine the utilization of the SSU in ED, we retrospectively analyzed 247 patients admired in SSU from the ED, and compared the average hours per patient with acute gastroenteritis spent in the ED doing the 2-month intervals before(July-August 1996) and after(July-August 1997) the establishment of the SSU. The following results were obtained; 1. The total patients consist of EM 92(37.2%), GS 48(19.4%), IM 24(9.7%), PS 21(8.5%), OS 20(8.1%), OBGY 14(5.7%) and others 28(11.3%). 2. The results of EM patients admitted in SSU from ED 1) Sex ratio of male to female was 1:1.1 and the mean age was 37.3+/-16 years. 2) In diagnosis, acute gastroenteritis was 29 cases(31.5%), multiple contusion 14 cases(15.2%), drug intoxication 12 cases(13%), limb laceration 6 cases(6.5%), tendon rupture offhand 6 cases(6.5%), and others 19 cases(20.6%). 3) Mean length of stay in ED was 9.18 hours. 4) Among 92 patients to the SSU, 79 patients(85.9%) were discharged, 11 patients(11.9%) formally admired to hospital and 2 patients(2.2%) transferred to otherhospital. The mean hospital stay time of the patients admitted to SSU was 2.6 days. 3. There was a significant reduction in the average stay time spent in the ED by treat-and-releasing patients with acute gastroenteritis after the establishment of the SSU(from 14.65+/-9.6 to 7.52+/-5.4 hr/patient, p<0.001). Conclusively, the establishment of the SSU can shorten the average stay time that treat-and-releasing patients spend in the ED, and reduce the number of admixed patients waiting in the ED.

BACKGROUND: Elevated systemic levels of pro-inflammatory cytokines cause hypotension during septic shock and induce capillary leakage in acute lung injury. Manassantin B has anti-inflammatory and anti-plasmoidal properties. This study examined the effects of manassantin B on lipopolysaccharide (LPS)-induced inflammatory response in murine macrophages. METHODS: RAW 264.7 macrophage cells were incubated without or with (1, 3 and 10 microM) manassantin B and without or with (100 ng/ml) LPS. Manassantin B dissolved in phosphate buffered saline was added to the medium 1 h prior to the addition of LPS. The degree of activation of mitogen-activated protein kinase (MAPK) including extracellular signal-regulated kinases 1 and 2 (ERK1/2), c-Jun amino terminal kinases (JNK) and p38 MAPK, and the level of interleukin (IL)-1beta were determined 30 min and 24 h after the addition of LPS respectively. RESULTS: Manassantin B inhibited the production of IL-1beta and attenuated the phosphorylations of ERK1/2 and p38 MAPK, but not that of JNK, in RAW 264.7 cells treated with LPS. CONCLUSIONS: Manassantin B reduces LPS-induced IL-1beta expression through effects on ERK1/2- and p38 MAPK-mediated pathways. Manassantin B has potential as a potent anti-inflammatory drug for use in pathological processes such as sepsis or acute lung injury.
