The relationship between lead related subject symptoms and lead exposure indices was studied in 435 male lead workers in thirteen lead using industries. 212 male office workers who were not exposed to lead occupationally were also studied as a control group. Fourteen lead related symptoms were selected. They were further subdivided into 4 sub-symptom groups such as 1) gastrointestinal, 2) neuromuscular and joint 3) constitutional, and 4) psychological symptoms. Symptom questionnaires were provided to the workers and filled up by themselves and reconfirmed by interviewer(doctor). The test used for the evaluation of lead exposure were blood lead (PbB), zinc protoporphyrin in whole blood(ZPP), hemoglobin(Hb), hematocrit(Hct), delta-aminolevulinic acid in urine(DALA). The results obtained were as follows; 1. The higher prevalence rate in the sub-group of neuromuscular and joint symptoms was observed in occupationally lead exposed subjects than non-exposed subjects. Among the sub-groups, the most frequent symptom was "numbness of finger, hands of feet", and the prevalence of the symptom of "arthralgia", "weakness of fingers, hands or feet" and "myalgia" were higher in order. 2. While the symptom which showed the biggest difference of prevalence rate among the 14 symptoms between exposed and non-exposed subjects was "numbness of fingers, hands or feet" , the symptom which showed the highest prevalence rate was "feeling tired generally" in exposed and non-exposed subjects, but no statistical difference of symptom prevalence were observed. 3. In total study population, PbB and ZPP had dose-response relationship with 4 symptoms of neuromuscular and joint symptoms ("numbness of finger, hands or feet", "arthralgia", "weakness of fingers, hands or feet" and "myalgia") and one symptom of gastrointestinal group("intermittent pains in lower abdomen"). 4. In lead exposed workers, only neuromuscular and joint symptoms group showed dose-response relationship with PbB and ZPP. 5. In lead exposed workers, the prevalence rate of overall symptoms of lead workers with age below 39 years was higher than that of lead workers with age above 40. While neuromuscular and joint symptoms group had a dose-response relationship with PbB in former group, it had a dose-response relationship with ZPP in latter group. 6. Age adjusted odds ratios of symptoms of non-exposed with exposed and odds ratios of low exposed with high exposed workers showed the dose-response relationship of lead exposure with neuromuscular and joint symptoms group("numbness of fingers, hands or feet", "arthralgia", "weakness of fingers, hands or feet" and "myalgia") and gastrointestinal symptoms group("intermittent pains in lower abdoman").

The CT digital radiography is a new accurate technique for measuring the long bone length. Authors performed acomparative study on accuracy, time and film consumption and radiation dose between conventional spot scanogramand CT scanogram. We used two femur and two tibia specimen for materials, the Somatom II(Siemens) for CTscanogram, and Rad Check(Voctoreen) for radiation dosimetery. There was no significant difference in accuracybetween direct measurement, conventional scanogram and CT scanogram(lesser than 1% difference). The examinationtime of conventional scanogram was about 35 minutes, CT was 15 minutes, and the film consumption of spot scanogramwas 3 of 14x17'' size, but the CT scanogram need only one 8x10'' film for completion of study. The radiation doseof hip, knee and ankle joint were 220 mRad, 365 mRad, respectively, in spot scanogram, but it was lesser than 5mRad in all joints in CT scanogram. The advantages of the CT scanogram are simple, rapid and reduced radiation.

As the newly reconstructed nipple tends to be flattened, especially if submitted to pressure, prudent dressings using various protective devices as a physical support against pressure on a new nipple is important. We used a breathing bag connecting tube as a protective device in nipple reconstruction. A breathing bag connecting tube recycled was cut and trimmed at 1cm above the height of the reconstructed nipple. Before stitch out, the newly reconstructed nipple with a local flap was dressed and protected in this way for 10 days after surgery. After stitch out, patients learnt how to manage the new nipple at home. The sole means of nipple dressing was affixing the breathing bag connecting tube with adhesive tape. Two patients had worn the tube for two months with the best compliance. Owing to the soft composition of the tube material, it is possible for a surgeon to have an easy cutting and trimming of the tube at appropriate heights as well as for a patient to show better compliance yielding better results. The cost factor is another advantage.
