Three cases of human embryo of Carnegie stage 13 were described. The CR length of these embryos were 3.0-5.3mm. The authors made a reconstruction model using photograph, photocopy and computer. These embryos were characterized externally by 4 limb buds and 4 pairs of branchial arches, and internally closed otic pits, appearance of venous valves, septum primum and foramen primum in the heart, beginning of the right and left lung buds, appearance of lens disk.

An automated percutaneous lumbar discectomy(APLD) have been apphed for contained lumbar disc herniation. But suggested that more exclusion criteria than disc containment was needed to improve success rate. The purposes of this study are to evaluate cIinical outcome of more than 4 years follow up of APLD, to analysis the cause of failure for longer follow up period, and to define prognostic factor of APLD. The l04 patients with contained lumbar disc herniation were treated with APLD from March 1990 to November 1992 in National Medical Center. The surgical candidates were contained focal disc herniation in MRI, sciatica than back pain, failure to conservative management at least 6 weeks and clinical and radiological correlation. And patient were excluded from this data if they had history of previous lumbar surgery and compensation claims. Among them 74 cases were followed up for over 4 years (Mean: 5.3 years). The results were accessed by questionnaire using telephone or OPD follow up. The overall success rate was 84% on 3 months follow up, but 68.9% on more than 4 years follow up by four subjective criterias (Onik, 1987). Causes of decreasing success rate were reoperation, recurrence without specific cause or after sprain and heavy work. 76% of failed cases occurred within 1 year and 40% of them underwent open discectomy. The patient sex, treated level, duration of symptom were not influenced on success rate, but age was factor related to success rate. In this study we can assess the effectiveness of APLD within 3 months in most cases and then change treatment option according to patients status, and it seems that we need more exclusion criteria than disc containment in MRI and refined patient selection in order to decrease the failures.

We treated the 90 wrists (83 patients) with de Quervain's disease, and studied retrospectively the factors affecting the result of treatment, and the results of several treatment modalities, compared with published series of this disease. There was significant association between outcome and duration of symptoms before treatment, but age, sex, associated disease, and hand dominance were not associated(chi-square test, p < 0.05). And 75 wrists received single injections of steroid and local anesthetic into the tendon sheaths with complete pain relief in 59 wrists (69%). Furthermore, an additional injection gave pain abatement in 6 wrists. And regardless of treatment method, 95% of the whole patients had satisfactory outcome at a mean of 54 months (minimum follow-up, 45 months). We concluded that injection of steroid is the preferred initial treatment in de Quervain's disease, giving complete and lasting relief in 87% of cases.

Anaphylaxis is a life - threatening syndrome elicited in a hypersensitive individual on subsequent exposure to a sensitizing antigen with, reactions ranging widely in severity from mild pruritus and criteria to shock and death. Anaphylaxis occurs in the United States at rates estimated to be as high as one in every 3000 inpatients and may account for more than 500 deaths annually. Preparations of kelp Laminaria digitata are used as tents in gynecologic procedures to dilate the cervix, and the kelp consists principally of a glucagon carbohydrate called laminarin. Laminarin is thought to function as the active ingredient in dilatation by changing osmotic pressure or uterine prostaglandin metabolism. The tent is inserted into the cervix several hours before the procedure. As the cervix desiccates and dilates, the tent develops an hourglass shape. Recently, we experienced one patient with anaphylaxis to laminaria diagnosed by skin test and showing good response to treatment.
