Mid-trimester abortion using prostaglandin E2 gel.

Nineteen cases of mid-trimester pregnancy were terminated using prostaglandin E2 gel applied intracervically. In this prospective study, 42% were primipara with gestational age at the time of abortion between 16 and 28 weeks. The induction to abortion time was 19.65 +/- 10.37 h with a success rate of 89%. The average number of applications was 1.8 times (range 1-3 times) and the average dosage of prostaglandin required was 5.5 mg (range 3-9 mg). The complications were minimal except retained placenta in 42% of cases. Prostaglandin E2 in form of gel applied intracervically is an effective alternative to the commonly used hypertonic saline or, more recently, to prostaglandin analogues for termination of pregnancy in the second trimester.     

Statistical MUNE: A comparison of two methods of setting recording windows in healthy subjects and ALS patients

OBJECTIVE: To address the issue as to how best to perform statistical MUNE, we applied two different approaches and compared results in healthy subjects and ALS patients. METHODS: Twelve normal subjects (women 8, mean age 52years) and 11 ALS patients (women 4, mean age 54years) underwent two consecutive MUNE studies, which differed in terms of setting and modifying the recording window. These are referred to as the 'expansion' and 'narrowing' methods, respectively. Size-weighted average (Av) SMUP and MUNE values were obtained using the two methods, and compared in control and patient groups. RESULTS: Expansion method-derived Av SMUP sizes and MUNE values differed only slightly from those obtained using the narrowing method in healthy subjects, whereas the narrowing method resulted in significantly larger Av SMUP sizes and smaller MUNE values than the expansion method in ALS patients (Wilcoxon signed ranks test, p=0.003). The sizes of tested areas (mean+/-SD) were significantly larger for the narrowing method than the expansion method in both subject groups with much greater difference in ALS patients; 9.6+/-3.1% vs. 7.9+/-1.7% in healthy subjects and 16.1+/-5.1% vs. 11.2+/-3.0% in ALS patients (Student t-test, p<0.01). CONCLUSIONS: The present study shows, unlike that found in normal subjects, that the results of statistical MUNE in ALS patients are heavily dependent on the approach used to set and modify recording windows. SIGNIFICANCE: The expansion method using a 10%-sized window is likely to suffer from systemic errors due to the ceiling effect and the sampling of artifactually small motor units in ALS patients. The authors recommend that the narrowing method be considered as an alternative that avoids these problems.     

Induced abortion in China and the advances of post abortion family planning service

<正>This is a review of current situation of induced abortion and post abortion family planning service in China. Induced abortion is an important issue in reproductive health. This article reviewed the distribution of induced abortion in various time, areas, and population in China, and explored the character, reason, and harm to reproductive health of induced abortion. Furthermore, this article introduces the concept of Quality of Care Program in Family Planning, and discusses how important and necessary it is to introduce Quality of Care Program in Family Planning to China.

河豚鱼中毒15例的救治体会

目的探讨河豚鱼中毒的治疗方法及影响预后的因素。方法回顾性分析我院1996年1月-2006年4月收治的15例河豚鱼中毒的病例资料。结果15例均有恶心、呕吐，腹痛，口唇、舌尖、指端麻木，四肢乏力，外周血白细胞计数增高，肝功能损害5例，心电图可见房室传导阻滞6例。1例于中毒后16h死于呼吸循环衰竭。结论目前河豚鱼中毒尚无特效解毒剂，死亡率50％，死亡主要原因为脑干麻痹，导致呼吸循环衰竭。主张尽早清除毒物，应用维生素B1，B6，B12等以及士的宁注射治疗神经肌肉麻痹，有呼吸衰竭者尽快行气管插管机械通气辅助呼吸。     

A magnetic resonance imaging study of putamen nuclei in major depression.

The basal ganglia are recognized as putative mediators of certain cognitive and behavioral symptoms of major depression. Moreover, patients with basal ganglia lesions have repeatedly exhibited significant affective symptomatology, including apathy, depressive mood, and psychosis. Using high resolution, axial T2 intermediate magnetic resonance images, and a systematic sampling stereologic method, we assessed putamen nuclei volumes in 41 patients with major depression (DSM-III) and 44 healthy volunteer controls of similar age. Depressed patients had significantly smaller putamen nuclei compared with controls. Age was negatively correlated with putamen size in both groups. These results are the first demonstration of diminished putamen volumes in depression and further support a role for basal ganglia structures in the etiopathogenesis of depression.

Benign osteoblastoma of the occipital bone: Case report and literature review

We present a case of benign osteoblastoma of the occipital bone. Benign osteoblastoma is an uncommon primary bone tumor, which usually involves the vertebrae and the long bones. This tumor rarely develops in the calvaria, showing a preference for the temporal and frontal bones when it does. To the best of our knowledge, this case is only the eighth reported case of benign osteoblastoma confined to the occipital bone. A 20‐year‐old male presented with a mild tender mass lesion of the occipital area, just below the lambda. Plain X‐ray films and CT scans demonstrated an osteolytic mass surrounded by the sclerotic rim within the diploic space. MRI proved to be effective for the evaluation of the intracranial and intraosseous extensions of the tumor. However, it was very difficult to formulate a differential diagnosis against other osteoblastic tumors, or osteoid osteoma, in view of its radiological appearance. The final diagnosis was obtained by careful consideration of the histopathological characteristics of the tumor combined with its clinical and radiological features. Although generally regarded as benign, a complete resection is preferred over conventional curettage as this can guard against possible recurrence and malignant transformation.     

An Unusual Form of Skin Tuberculosis Following B.C.G. Vaccination

A 25-year-old female has had brown to erythematous telangiectatic patches and grouped papules on her face, neck, arm, and trunk since childhood following B.C.G. vaccination. Histopathologically, the lesions consisted of hyperkeratosis, slight acanthosis, tuberculoid granulomas with some Langerhans type giant cells in the mid-dermis. Although various forms of cutaneous tuberculosis after B.C.G. vaccination have been reported, it was difficult for us to assign the patient's skin lesion to any specific disease entity. Remission of her cutaneous lesions occurred clinically and histopathologically after treatment with isoniazid and rifampin.
