Proximal femoral focal deficiency: radiologic analysis of 49 cases

Proximal femoral focal deficiency, an uncommon congenital anomaly, necessitates early radiologic classification for surgical planning and treatment. Objective radiographic criteria, including femoral length index, acetabular depth index, acetabular angle index, and shape of the proximal femur were determined in 49 patients before cartilaginous ossification of the femoral capital epiphysis; final classification was based on follow-up radiographs or findings at arthrography or surgery. These parameters were analyzed to determine the accuracy and contributions of each in classification. Correct classification into one of three groups was possible in 86% of cases with use of three of the parameters: femoral length index, acetabular depth index, and shape of the proximal femur. The acetabular angle was found to contribute insignificantly to classification. Magnetic resonance imaging, used in only one case, depicted the nonossified cartilaginous femoral capital epiphysis, thus obviating the need for invasive diagnostic procedures and facilitating early classification.     

Giant hepatic hemangiomas: diagnostic and therapeutic dilemmas

This report describes four cases of surgically treated giant hepatic hemangiomas which illustrate some diagnostic and therapeutic difficulties encountered in the management of this condition. An important diagnostic triad has emerged, which should alert the physician to the possibility of a complicated hepatic hemangioma: the clinical signs of an acute inflammatory liver process contrasted with a normal white blood cell count and liver function tests. Hemangiomas of the left lobe were either missed or poorly demonstrated on selective hepatic angiographic examination, and in two patients the diagnosis was made only at the time of laparotomy. Hepatic resection was successfully performed in all patients; there was minimal morbidity and none of the patients died. In two patients with multiple hemangiomas, only symptomatic or easily resectable lesions were removed. All patients are alive and well; three have been followed up for more than 5 years. We conclude that resection in asymptomatic cases should be carried out only in those cases that require a diagnostic laparotomy and in those where the lesion is easily resectable. The majority of patients with symptomatic and complicated tumors should undergo resection, but even in these patients continued conservative treatment is appropriate when the risk of major resection outweighs the small risk of live-threatening bleeding.     

44Sacral extracorporeal magnetic stimulation is an effective treatment for pelvic floor dyssynergia; Comparative study with biofeedback therapy

Background: Recent development of extracorporeal magnetic stimulation (ECMS) which uses current‐changing magnetic fields allows the induction of electrical stimulation in the desired deep tissue. Recent study showed the sacral nerve stimulation reduces corticoanal excitability that may play a functional role in anal continence mechanisms. Preliminary study shows that ECMS of sacral nerve can modify pelvic floor function and expel rectal balloon in patients with pelvic floor dyssynergia (PFD). Aims: To evaluate the effect of ECMS compared with biofeedback therapy (BF) in patients with PFD. Methods and Materials: Thirty‐eight patients who fulfilled Rome II criteria for PFD by colon transit time and anorectal function tests, were randomly treated with 8 sessions of ECMS (2/weeks; n = 19) at prone position or BF (2/weeks; n = 19) at sitting position. Stimulation parameters were set at 50–80% of maximum intensity, 10 and 50 Hz frequency, 3 s burst length with 3 and 6 s off using arm‐typed stimulator (BioCom‐1000, Mcube Co., Korea). Symptom scores for constipation with/without anorectal function test were repeatedly measured after each treatment. Response was defined as 50% or more decreased symptom score after treatment (partial response: 30–50%, poor: <30%). Results: Fifteen patients (age 49.1 ± 13.4 years, mean ± SD; 4 men) completed 8 session of BF and 14 patients (54.5 ± 17.6 years, 3 men) completed 8 session of ECMS. Four patients of BF group discontinued treatment due to unsatisfactory therapeutic effect (n = 1) and withdrew consent (n = 3) and 5 patients of ECMS group discontinued treatment because of same reasons (n = 1, 4). Total symptom scores were significantly decreased after treatment of 8 session in both treatment groups (13.4 ± 6.6 vs. 4.3 ± 4.0 for BF, p = 0.009; 14.9 ± 5.6 vs. 3.4 ± 4.0 for ECMS, p < 0.001). Bowel movements per week were also significantly increased after treatment in both groups (median 2 vs. 7 for BF, p = 0.035; median 2 vs. 7 for ECMS, p = 0.008). Thirteen out of 15 patients showed response in BF group and 12 out of 14 showed good response in ECMS group. No adverse effects in both groups. Conclusions: ECMS is as effective as BF for the treatment of PFD. Long‐term effect of ECMS for the patients with pelvic floor dyssynergia need to be evaluated in the near future.     

Aspergillus brain abscess. A case report

The history and findings in a patient with erythroleukaemia who developed a fungal brain abscess during the agranulocytic phase of induction treatment is reported. The radiological features of fungal infection are reported, with emphasis on the importance of clinical judgement in making the diagnosis. The autopsy findings further illustrate the increasing importance of this previously very rare condition.
