The increasingly successful results of hair restoration surgery in the last years have developed the interest and the confidence of patients and it is the most frequently performed esthetic surgery among male patients. Currently, various kinds of techniques for hair restoration surgery including hair transplantation, scalp reduction, and scalp flaps are performed in our clinic. Among these, hair transplantation is the basic and the most popular procedure, which can be performed not only by itself but also in conjunction with other procedures. 123 consecutive cases of hair transplantations were peformed from Jan. 1995 to Feb. 1996 for male pattern baldness, traumatic alopecia, and female pattern baldness under out patient base. The authors introduced a new classification for male pattern baldness, which are the type M, O, C, U, M-O, and C-O after alphabet to make simple and easy for clinical application. The ancillary procedures were scalp reduction, preauricular flap, and scalp expansion. An ellipsis of hair bearing scalp taken from the occipital area was sliced into slit-, mega-, mini-, and micro-grafts. The survival rate of the grafts was over 90% with minimal complications. This hair transplantation technique enabled us to achieve a good density and more natural looking hair with avoidance of cobble stoning and apparent scar.

Mullerian agenesis or dysgenesis, rare developmental anomaly presenting as primary amenorrhea, is characterized by absence of vagina and absence or rudimentary development of the uterus. Anatomic anomalies of the axial skeleton and kindney often accompany this psychologically devatating condition. There are various methods of surgical treatment for congenital absence of the vagina. The six cases reviewed in this paper were all treated with McIndoe technique. All of 6 women experienced satisfactory sexual activity and were satisfied with vaginal depth following vaginal creation using a split thickness skin graft technique. Despite the existence of several alternative methods, the McIndoe technique is a relatively simple and highly successful procedure and hence is still prefered by many surgeons.

BACKGROUND: A good doctor-patient relationship should be based on mutual understanding and reliance. Proper conversation and same understanding of the use of this terminology is needed. This study was designed to make a comerstone to establish appropriate medical terminology by means of investigation of the meaning of 'neurotic' among family' physicians. METHOD: A questionnaire was sent to 971 family doctors registered as regular members in the Korean Academy of Family Medicine. We analysed 184 returned questionnaires. We calculated the percent for each item. Chi-square test used to analyse demographic characteristics and compare whether the word 'neurotic' has been used or not, and whether it was a proper medical terminology or not. RESULT: 82.6% of responders(152/184) were used to 'neurotic' as a medical terminology. Doctors in their thirties were the least using group(78.7%) and doctors working in university hospitals rarely used them being statistically significant (p<0.000). 82.5% of the doctors in using 'neurotic' responded it is not an appropriate terminology. The most frequent situation in using it was 'patient appealed organic symptom without abnormal lab result'(51.1%). The target diseases were not organic disorders such as functional dyspepsia(64.1%), tension headache(58.5%), psychosomatic or somatoform disorder(54.9%). 59% of the patients diagnosed as 'neurotic' gave unsatisfying responses. Family doctors recommended substituting to terminology such as 'functional'(33%), 'psychogenic'(31.8%), and 'stress-induced'(25.0%). CONCLUSION: Most family doctors were used to the word 'neurotic' but they did not think it was an appropriate terminology. There fore, other substitute words should be faken into consideration.

PURPOSE: This study is designed to determine the prevalence of cardiovascular autonomic neuropathy and its relationship to risk factors in adolescents with diabetes mellitus(DM). METHODS: Ninety-two diabetic patients(80 with type 1 DM and 12 with type 2 DM), ranging from eight to 26 years of age, were studied for cardiovascular autonomic function, and the relationship to age, duration of diabetes, glycated hemoglobin(HbA1c), urinary albumin excretion, and the presence of diabetic retinopathy and abnormal nerve conduction velocities(NCV) were analysed. Autonomic function was assessed by measuring heart rate variation during valsalva manoeuvre, deep breathing and standing from a lying position(30 : 15 ratio), and postural hypotension. RESULTS: Among patients with type 1 DM, 22.5% had early, 8.7% had definite, and 1.3% had severe autonomic dysfunction, and among patients with type 2 DM, 16.7% had early, 8.3% had definite, and 8.3% had severe autonomic dysfunction. On logistic regression analysis including both type 1 and type 2 diabetic patients, the age of the patient(OR=1.133(1.003-1.279), P< 0.05) and duration of diabetes(OR=1.148(1.009-1.307), P<0.05) significantly predicted cardiovascular autonomic dysfunction while HbA1c, blood pressure, urinary albumin excretion, and presence of diabetic retinopathy and abnormal NCV did not. The valsalva ratio was borderline or abnormal in 31.5% of patients, the heart rate variation on deep breathing in 41.3%, the 30 : 15 ratio in 14.1%, and postural hypotension in 9.8% of patients. The valsalva ratio and the heart rate variation on deep breathing significantly predicted cardiovascular autonomic dysfunction, but the 30 : 15 ratio and postural hypotension did not. CONCLUSION: Cardiovascular autonomic dysfunction was found in 32.6% of diabetic patients and 10.8 % of patients had definite or severe involvement. The risk of cardiovascular autonomic dysfunction increased with the patient's age and the duration of DM. This study suggests that the valsalva ratio and the heart rate variation on deep breathing are the most useful tests in evaluating the cardiovascular autonomic function in children and adolescents with DM.

This study was performed to observe the present status of intestinal parasitic infections in a remote island, Yondo, located in southern part of Jeonranam-do(province), Korea. In February and May 1988, total 1,011 individual stool samples were collected and examined for intestinal helminths and protozoa using formalin-ether centrifugal sedimentation technique. The results are summarized as follows: Of 1,011 ingabitants examined, 398(39.4%) were positive for intestinal parasites. Helminth positives were 372(36.8%), and protozoan cyst positives were 56(5.5%). Ten species of parasites were found. Trichuris trichiura revealed the highest infection rate of 27.5%, Ascaris lumbricoides 17.4%, Taenia sp. 5.8%, Entamoeba coli 3.3%, Giardia lamblia 1.5%, Endolimax nana 0.8%, Hymenolepis nana 0.4%, hookworm 0.2%, Trichostrongylus orientalis 0.2%, and Entamoeba histolytica 0.2%, respectively. The female group showed higher positive rate (44.0%) than males (34.7%). Also, higher positive rates were observed among adults as compared with the group younger than 10 years old. Average value of E.P.G. was 1,876(range 200-17,800) in A. lumbricoides positives, and 327(range 200-1,600) in T. trichiura positive cases. In helminth egg positive cases, single infection was 63.4%, double infection 34.7%, and triple infection 1.9%, respectively. Among protozoan cyst positives, single infection was 94.6%, and double infection was 5.4%. The present study revealed that the prevalence of intestinal parasites among inhabitants in Yondo island is still so high that special control measures should be performed.

Lipofibromatous hamartoma of median nerve is an extremely rare tumor that involves the palmar aspect of the hand, wrist and distal forearm. Other terms to describe this condition include macrodystopia lipomatosa of median nerve and median nerve territory-oriented macrodactyly. Lipofibromatous hamartoma is the most common condition associated with macrodactyly in the hand Also it most commonly involves the median nerve and is one of the causes of carpal tunnel syndrome. We present a review of our experience with this unusual neoplasm and give a detailed follow-up on patient treated by surgical exploration with carpal tunnel release.

The clinical validity of a korean EEG and EP mapping system(Neuronics) was evaluated with schizophrenic patients(n=20), normal controls(n=19), and 10 patients with central nervous system disease(8 patients with cerebrovascular accident, 1 patient with brain mass, and 1 patient with periodic paralysis). In the normal control group, the pattern of resting computerzied EEG with eyes closed showed normal parieto-occipital dominance of alpha wave. Compared with normal controls, schizophrenic patients had more delta activity in the frontal region, and less alpha activity especially in the parieto-occipital region. In most cases patients with cortical organic lesions(n=5) revealed increased delta and theta activity and decreased alpha activity on the lesion areas. These findings were compatible with their MRI and clinical findings. However in the cases of subcortical lesions(n=5) EEG showed various findings which suggest diverse influences of subcortical abnormalities on cortical activities. The P300 of schizophrenic group was smaller and more delayed than those of normal controls. These results are generally compatible with the previous studies using other EEG and EP mapping systems consequenty and suggest that the this EEG and EP mapping system(Neuronics) has clinical validity.

OBJECTIVE: The study reports the clinical outcomes and complication rates of microsurgical clipping of unruptured paraclinoid aneurysms. METHODS: From July 1997 to December 2008, 61 patients underwent microsurgical clipping for 61 unruptured paraclinoid aneurysms in our institute. Entire medical records, radiographic data, and operation records were reviewed retrospectively. RESULTS: After the microsurgical clipping, complete obstruction was achieved in 56 patients (91.8%). Visual disturbance (nine cases, 14.8%) was the most frequent complication. Overall, 59 patients (96.7%) had a good long-term outcome (Glasgow outcome scale score of 4-5 3 months post-operatively). CONCLUSION: For patients with paraclinoid aneurysms, satisfactory outcomes can be achieved by microneurosurgical management. These results will be useful when considering treatment of an unruptured paraclinoid aneurysm.
