Bilateral perioral sensory symptom after unilateral stroke: Does it have a localizing value?

Bilateral perioral sensory dysfunction due to unilateral cerebral lesion is rare, and has been thought to be caused by midline brainstem lesions. Six patients are described herewith, with bilateral perioral sensory symptoms due to unilateral strokes that do not involve the mid-brainstem region. Brain-computed tomographic scan and magnetic resonance imaging demonstrated unilateral cerebral strokes in the thalamus, posterior limb of the internal capsule, basal ganglia, fronto-parietal cortex and the insular-frontal subcortical area. This observation suggests that bilateral perioral sensory symptoms do not have a localizing value. Possible pathogenetic mechanisms for this sign are discussed.     

Reversible reorganisation of the motor cortical representation of the hand in cervical dystonia.

Previous work has suggested that there may be a widespread disturbance of motor control mechanisms in patients with cervical dystonia. In the present study, we used transcranial magnetic stimulation to investigate the topography of the corticomotor projection to the abductor pollicis brevis (APB) muscle in 10 subjects with idiopathic torticollis. Threshold-adjusted stimuli were delivered at multiple scalp sites during a low-level voluntary contraction of the APB, and maps were generated of motor evoked potential amplitude versus scalp site. The cortical maps for the APB on the side opposite to the direction of head rotation were displaced laterally or posteriorly in all subjects and reverted to a more normal position after botulinum toxin injection of the cervical muscles in 5 subjects. The findings point to a reversible reorganisation of the corticomotor representation of the hand on the same side as the sternocleidomastoid (SCM) muscle that is involved in producing the dystonia. These results provide further evidence for the involvement of cortical centres and for a more widespread abnormality of motor control mechanisms in focal dystonia. The findings also support the notion that head turning is chiefly mediated by the hemisphere ipsilateral to the direction of the head rotation by means of a corticomotor projection to the contralateral SCM.     

Expression of human T-cell lymphotropic virus type-1 gene products in the short-term cultured skin tissues of an adult T-cell leukemia/lymphoma patient with cutaneous manifestations.

Adult T-cell leukemia/lymphoma (ATLL) is recognized as a disease etiologically associated with human T lymphotropic virus type-1 (HTLV-1) infection, but, neither viral replication nor specific virus antigen expression have been detected on ATLL cells distributed in organs, including skin. To examine the latent expression of HTLV-1 in the cutaneous lesions of ATLL patients, we cultured the lesional skin tissues in vitro and applied immunofluorescence staining with mouse monoclonal antibodies Lt-4, GIN-14, and F10, which react with p40tax, p19 and gp21, respectively. We recognized HTLV-1 specific antigens on clustered ATLL cells only in the deeper dermis of the skin after 24 hrs cultivation of the lesional skin tissue from an ATLL patient in RPMI-1640 medium supplemented with 20% fetal calf serum. In the electron microscope, we observed HTLV-1 like particles, 80-140 nm in diameter with envelope and core structures, in the same tissue specimen. These findings suggest that HTLV-1 gene products may be expressed in the skin lesions of ATLL patients and involved in the pathogenesis of skin eruptions in cutaneous type ATLLs. To our knowledge, this is the first report that envisages the potency of intracutaneous HTLV-1 expression in vivo.     

Adenoma malignum (minimal deviation adenocarcinoma) of the cervix responsive to hormonal treatment

Adenoma malignum (AM) is a rare variant of cervical adenocarcinoma with an unfavorable prognosis despite radiation therapy, surgery, or chemotherapy either alone or in combination. Hitherto, however, the effectiveness of hormonal therapy for this condition has not been evaluated. We report on a patient with cervical AM treated with progesterone before surgery. The progesterone therapy resulted in a complete clinical response and partial surgical response. Later on the treatment was changed to tamoxifen because of side effects of the progesterone treatment. The patient is still without evidence of disease 42 months after the start of the hormonal therapy. The progesterone receptor analysis on the biopsy was clearly positive. This is, to our knowledge, the first case of an AM responsive to hormonal treatment. Furthermore, this is the first case of an AM with bone metastases at the time of primary diagnosis.     

良性淋巴上皮病、淋巴上皮癌、MALT淋巴瘤的关系

良性淋巴上皮病(benign lymphoepithelial lesion)、淋巴上皮癌(lymphoepithelial carcinoma)、黏膜相关淋巴组织型结外边缘区B细胞淋巴瘤(MALT淋巴瘤)(extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue,MALT lymphoma)是3种性质不同但又存在某些关联的病变,本文对3种病变的病因、组织病理学表现及三者之间的关系进行了介绍,并结合叶为民等论文中的一些内容进行了简要探讨。     

Noonan syndrome associated with central giant cell granuloma

We report a case of Noonan syndrome associated with central giant cell granuloma. The patient was a 101/2-year-old boy with the chief complaint of proptosis of the right eye. He also had various malformations such as short stature, webbed neck, pectus excavatum, cubitus valgus, pulmonary valve stenosis and patent foramen ovale, a characteristic face appearance and cryptorchidism and so on. Chromosome analysis showed a 46, XY karyotype. A computed tomographic scan and magnetic resonance imaging showed a mass originated from the lateral wall of the right maxillary sinus. The patient underwent Caldwell-Luc operation. Histological examination of the mass showed the characteristics of central giant cell granuloma. This case report describes a patient with the features of the recently described Noonan-like/multiple giant cell lesion syndrome.     

Difficulties using the Franco-Italian Glossary in assessing toxicity of cervical cancer treatment

Shakespeare TP, Ferrier AJ, Holecek MJ, Jagavkar RS, Stevens MJ. Difficulties using the Franco-Italian Glossary in assessing toxicity of cervical cancer treatment. Int J Gynecol Cancer 1998; 8: 51–55
We assessed the toxicities of patients treated for cervical cancer using the revised Franco-Italian Glossary (FIG). A total of 69 separate complications were appraised in 47 patients; however, only 43.5% of these side-effects could be accurately graded. In all, 56.5% of toxicities could not be scored for a variety of reasons: (1) the FIG does not account for all possible complications of cervical cancer treatment; (2) some important toxicities are regarded as too minor to be graded; (3) subjective assessment of some side-effects did not allow consensus to be reached when assigning a grade; (4) we could not accurately score toxicities using the FIG in a retrospective manner. Previous studies utilizing the FIG retrospectively have noted few problems with its use, with no indication of the number of toxicities unable to be graded. In view of the inability to grade the majority of complications in the present study in an accurate manner, we conclude that the revised FIG requires detailed data that are best collected prospectively and that several minor modifications of the glossary should be considered. Results of studies using the glossary retrospectively should be viewed with caution.     

Congenital cervical atresia: Report of seven cases and review of the literature

OBJECTIVE: Our aim was to evaluate the clinical course and management of congenital cervical atresia. STUDY DESIGN: This retrospective analysis included 7 patients referred to our clinic and a review of the medical literature. RESULTS: Including this case series, 58 cases of congenital cervical atresia have been reported in the literature. Forty-eight percent of patients had isolated congenital cervical atresia with a normal vagina whereas the remainder had either complete or partial vaginal atresia (“shortened blind vaginal pouches”). Surgical management has included abdominal hysterectomy or uterovaginal cannulation with or without vaginoplasty. In 59% of patients who underwent uterovaginal canalization procedures (23/39), normal menstrual bleeding was achieved. Four of these patients subsequently became pregnant and were delivered at term. CONCLUSION: Surgical canalization in selected patients with congenital cervical atresia can be successfully performed to provide patients an opportunity for conservative management, resulting in normal menstrual bleeding, resolution of cyclic pelvic pain, and some potential (albeit limited) for fertility.(Am J Obstet Gynecol 1997;177:25)
