A total of 50 patients with primary malignant melanomas received epifocal DNCB therapy. In 46 cases the tumors disappeared completely. Therefore, we partly refrained from excision of the treated area. Only 4 melanomas of great thickness did not respond satisfactorily. In the treatment of cutaneous metastases, however,…

This article reports our experience with 101 polytetrafluoreoethylene and 102 umbilical vein grafts inserted into the femoropopliteal and femorocrural arteries of 98 and 97 patients, respectively, during the last 5 years. These grafted extremities are compared to 416 saphenous vein grafts placed in similar arteries of…

15 cases of free gallbladder-perforation among 3,950 cholezystectomies during the last 15 years are discussed. There was no difference in the sex-distribution. The average age was 67 years. This factor together with delay of the operation because of atypical symptoms and perhaps a toxic agens in the gall are responsibl…

259 patients with primary proliferative polycythaemia (PPP) and idiopathic thrombocythaemia (IT) have been treated with 32P over the last 15 years. Complete follow-up data were obtained in 238 patients. PPP was the diagnosis in 183 patients and 76 patients had IT. The sex ratio in PPP was male/female 1.1:1 and in IT 1:…

Purpose. Improvements in the systemic management of Ewing's sarcoma of bone over the last 20 years have led to a dramatic improvement in survival. The corollary is that treatment of the primary disease requires re-evaluation, since a significant number of patients still suffer local relapse.Patients. The effect of radi…

To assess structural changes in retina after systemic immunosuppressive treatment in Vogt-Koyanagi-Harada (VKH) disease using spectral-domain optical coherence tomography (SD-OCT).The clinical data of 17 VKH cases (34 eyes) who consecutively attended the Beijing Tongren Hospital between December 2015 and December 2019…

BACKGROUND & AIMS: Screening colonoscopies are of uncertain benefit for persons with negative results from a fecal immunochemical test (FIT). We investigated detection of CRC by colonoscopy in asymptomatic, average-risk, FIT-negative subjects. METHODS: We conducted a retrospective, population-based cohort study of 96,…

The aim of the study was to evaluate the effectiveness and toxicity of CyberKnife (CK) stereotactic radiosurgery (SRS) and stereotactic ablative radiation therapy (SABR) of patients with prostate cancer bone metastases. Analysis of prognostic and predictive factors was also performed. Material consisted of 51 patients…

In a community-based prospective study, 6275 deliveries resulting in 6084 livebirths, 150 stillbirths (SB) and 167 neonatal deaths (NND) were monitored over a period of 3 years. The risk of an unfavourable outcome (SB or NND) in multiple pregnancies was more than ninefold that of singletons. Teenage mothers and those o…

OBJECTIVE: The aim of the study was to present the clinical characteristics, treatment, and outcomes of pediatric collagenous gastritis (CG). METHOD: This is a retrospective cohort study. Patients were identified via query of the institutional pathology database. Clinical data was obtained by review of medical records…

Purpose. The aim of this study is to determine the prevalence of lumbosacral transitional vertebra (LSTV) in a well-represented general population. Methods. For a retrospective cohort study, abdominal radiographs of adult subjects were queried with clear visibility of the vertebral body articulation of the last rib, al…

The timing of the placental mammal radiation has been a source of contention for decades. The fossil record of mammals extends over 200 million years, but no confirmed placental mammal fossils are known prior to 64 million years ago, which is approximately 1.5 million years after the Cretaceous-Paleogene (K-Pg) mass ex…

Human fossils dated between 3.5 and nearly 7 million years old discovered during the last 8 years have been assigned to as many as four new genera of the family Hominidae: Ardipithecus, Orrorin, Kenyanthropus, and Sahelanthropus. These specimens are described as having morphological traits that justify placing them in…

BACKGROUND: Since May 1992 we have used video-assisted thoracic surgery (VATS) for the treatment of the spontaneous pneumothorax. In this study we review the results obtained with this technique and we compare them with those obtained by conventional surgery (1976-1992). METHODS: 110 patients (98 males and 12 females,…

PURPOSE: Analysis of etiological factors and functional assessment of the eyes. MATERIAL AND METHODS: Optic disc hypoplasia was diagnosed in 43 children, aged 12 months--12 years, unilateral in 9 (20.9%). The follow-up ranged from 8 months to 9 years, the mean age of patients during the last examination was 10.4 years…

The authors present 34 medulloblastoma/primitive neuroectodermal tumours of the posterior fossa in children operated during the last ten years (1979-1989). Total removal of tumours has been performed in 13, and maximal-subtotal resection in 19 patients. Only four tumours were classified as small (group T1-T2). Partial…

The incidence of tuberculosis (TB) among Israeli-born children was studied. The incidence rates for Jews and non-Jews were compared at various ages and in different years. Non-Jews had higher rates of TB than had Jews at all ages. The difference between the two groups was largest at age 5 to 9 years (rate ratio, non-Je…

Adenocarcinoma arising in Barrett's esophagus has recently been described in two children aged 11 and 14 years. The long-term follow-up of Barrett's esophagus in children is not well described. We evaluated 16 cases of Barrett's esophagus in children treated at this institution during the last 16 years. Ages ranged fro…

METHODS: This retrospective longitudinal study included 15,616 adult patients (mean age at first CT, 53.0 ± 14.7 years; 7096 male, 8520 female) who underwen…

OBJECTIVE: To characterize metabolic control and verify whether it has any relation with socioeconomic, demographic, and body composition variables in children and adolescents with phenylketonuria (PKU) diagnosed in the neonatal period. METHODS: This cohort study collected retrospective data of 53 phenylketonuric chil…
