PURPOSE: To determine the significance of anomalous position of the gallbladder. MATERIALS AND METHODS: Sixteen patients with anomalous position of the gallbladder were evaluated for analysis. The diagnosis was confirmed by ultrasonography(15 patients) and oral cholecystography(1patient). Among those, six patients underwent CT scan and a patient had 99mTc-DISIDA scan. The images were analysed with respect to the location of the GB and configuration and associated abnormality of the liver and hepatobiliary systems. Medical records of each patient were also reviewed. RESULTS: Among 16 patients having an anomalous position of the gallbladder, nine had retrodisplaced gallbladder, four had left-sided gallbaldder, two had suprahepatic gallbladder, and one had floating gallbladder. Except for one patient, fifteen had abnormality in the liver such as focal atrophic or hypoplastic change and liver cirrhosis. Intrahepatic stones were demonstrated in 6 patients. CONCLUSION: Our results showed that anomalous position of the gallbladder was commonly associated with atrophy or hypoplasia of the liver rather than congenital in origin. The possiblity of an anomalous location of gallbladder should be kept in mind when GB is not in its normal location.

Mycelium of Hericium erinaceum isolate KU-1 was cultured in liquid medium (HL medium) and solid medium (Ko medium) at pH 4.0 in 28degrees C. 1.0% glucose or fructose was the most favorable carbon source, and 0.2% amonium acetate or NaNO3 was an exellent nitrogen source for mycelial growth as well as production of antimicrobial substances. The mixture of saw dust 70% with rice bran 30% (SR medium) was the substrate for formation of sporophores. The active substrates in extracts from mycelium, culture filtrate and fruiting body were separated by TLC. The solvent for TLC was EtOAc: Chloroform: MeOH (10 : 5 : 10). Phenol-like substances appeared at Rf 0.5~0.9, and fatty acid-like substances appeared at Rf 0.1~0.2. The purified materials from the extracts showed antimicrobial effects to Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Aspergillus niger, Candida albicans and Microsporum gypseum. The S. aureus was the most inhibited. Minimal inhibitory concentration (MIC) of purified white powder and the Hercenone derivatives against S. aureus were 5.65microg/ml and 1.85microg/ml, respectively.

Purpose:
The purpose of this study was to investigate the cause of acute fatal poisoning and the time of death by analyzing the National Emergency Department Information System (NEDIS) of South Korea.
Methods:
The NEDIS data from 2014 to 2018 excluding non-medical visits were used for this study. The patients with acute poisoning were extracted using diagnostic codes. The toxic substances were classified into pharmaceuticals, pesticides, gases, artificial poisonous substances, and natural toxic substances. Patients were classified according to the time of death, place of death, and region. In each case, the most causative substances of poisoning were identified.
Results:
There were 380,531 patients including poisoning-related diagnoses, of which 4,148 (1.1%) died, and the WHO age-standardized mortality rate was 4.8 per 100,000. Analysis of 2,702 death patients whose primary diagnosis was acute poisoning, the most common cause of poisoning death was pesticides (62%), followed by therapeutic drugs, gas, and artificial toxic substances. Herbicides were the most common pesticides at 64.5%. The proportion of mortality by time, hyperacute (<6 h) 27.9%, acute (6-24 h) 32.6%, subacute (1-7 d) 29.7%, and delayed period (>7 d) were 9.8%.
Conclusion
This study suggests that the most common cause of poisoning death was pesticides, and 60% of deaths occurred within 24 hours. The 71% of mortality from pesticides occurred within 6-24 hours, but mortality from gas was mostly within 6 hours. According to the geographic region, the primary cause of poisoning death was varied to pesticides or pharmaceuticals.

The vesicoureteral reflux (VUR) is frequently found among the patients with urinary tract infection (UIT) and some patients with VUR progress to reflux nephropathy. The presence of scarring at UIT is an important determinant in the selection of those at risk of progressive damage. 99m Technetium dimercaptosuccinic acid (99m Tc-DMSA) is a renal scanning agent provides a good quality of renal image as a result of preferential cortical accumulation. 99m Tc-DMSA scan and VCUG were performed in 133 patients diagnosed UTI at pediatric department of Kyung Hee University, College of Medicine from May, 1990 to May, 1992 The results were as follows: 1) VUR was seen in 27 children among 133 patients with UTI. The incidence was 20.3%. Under 1 year of age, male to female ratio was higher incidence of VUR. 2) Incidence of renal scarring was higher in patients with VUR than those of without VUR. 3) Grading of VUR in relation to age, the older the age, the lower the grade. 4) There is no correlation between renal scarring and grades of VUR. 5) In distribution of renal scarring, it was found to have tendency to develop at upper polar area, there was diffuse and multiple in patients with VUR. In conclusion the incidence of renal scarring was related to the age of onset, duration of UTI and the severity of the VUR and 99mTc-DMSA scan is mandatory in patient with UTI even without VUR in order to detect early phase of renal scarring.

A 45-year-old woman presented with keloidal nodules induced by moxibustion, which is made from mugwort powder. Keloids are benign hyperproliferative tumors of dermal connective tissue which usually result from excessive responses to cutaneous trauma in predisposed individuals. The lesions tend to occur on the upper part of the body as firm, raised tumors with a glassy surface and well demarcated borders. There are several available methods of treatment including intralesional corticosteroid injection, cryotherapy, surgical excision, laser therapy, pressure, radiotherapy and interferon-alpha injection. We report a case of a moxibustion-induced keloid in a 45-year-old female patient, who presented with multiple, round-shaped, erythematous to skin-colored, firm, cicatricial nodules on the moxibustion-applied sites.

A neurilemmoma is a rare nerve sheath tumor in dermatology. The tumors are usually solitary and affect woman more frequently than men, but with no particular affinity for any age group. It occurs commonly along the main nerve trunks of the extremities, especially the flexor surface of the arms, wrists, and knees. We report a case of neurilemmoma on the left nasal vestibule of 47-years old woman. The tumor was a solitary, pinkish, polypoidal papule which gradually increased in size. A review of the literature revealed extremely rare documented cases of neurilemmoma occurring in the nasal vestibule.

This study was designed to identify doxorubicin as a permanent chemomyectomy agent that overcomes reversible effect of botulinum toxin A. Doxorubicin was assessed for its ability to bring about a permanent chemomyectomy and the effects of pretreatment were observed to assess its ability to prevent any complications brought about by doxorubicin. A total of thirteen rabbits were assigned to the control group(n=3) and two experimental groups(n=5 for each group). To investigate the myopathic changes following the injections of the agent, both orbicularis oculi muscles of the lower eyelids of each rabbit in the control group were directly injected with single dose of 0.2ml normal saline. Group I were injected with 0.5mg/0.2ml of doxorubicin into the right eyelid and 1.0 mg/0.2 ml of doxorubicin into the left. Group II were given an intravenous injection of 35mg/kg of allopurinol as the pretreatment, then 30minutes later injected with 0.5mg/0.2ml of doxorubicin into the right and 1.0mg/ 0.2ml of doxorubicin into the left. The rabbits were examined daily to monitor the onset, duration and size of skin necrosis and histologically examined two and four months after initial injections. The myopathic change after doxorubicin injection was persistent and irreversible. The dose related effects of doxorubicin chemomyectomy were confirmed by the histologic finding. Skin necrosis occurred in all cases of doxorubicin injection(both 0.5mg and 1.0mg), however the allopurinol pretreatment decreased the size of the skin necrosis in case of the high dose(1.0mg) of doxorubicin. The combined use of allopurinol and doxorubicin reduced the myopathic change more effectively than doxorubicin use alone. Further study is needed to determine optimal dose and administration method, which we feel will contribute to safer and permanent chemomyectomy.

Lues maligna (malignant syphilis), also called noduloulcerative syphilis, is a kind of cutaneous secondary syphilis, which presents virulent clinical features and is frequently associated with an immunosuppressed state. Though there are many possible debilitative diseases, it has recently been more frequently presented in the human immunodeficiency virus (HIV)-infected patients. Other causes are diabetes and chronic alcoholism. Prompt diagnosis and early treatment can result in a desirable recovery and prevent spread of the disease. We report two cases of lues maligna associated with the underlying diseases of HIV-infection and diabetes. The skin lesions in these cases showed favorable results after treatment with benzathine penicillin.

Recurrent herpes zoster is rare and may be associated with various immunocompromised states. A 54-year-old woman who had previously been diagnosed with multiple myeloma, presented with severely-painful, grouped vesicles on the upper part of her right trunk area (T5-T7 dermatomes). Seven months before, she had been treated for herpes zoster on the left side of the lower trunk area (T10 dermatome). We report a case of recurrent herpes zoster which occurred bilaterally in a patient with multiple myeloma. The patient was treated successfully with famciclovir.
