Ultrasonographic measurement of shoulder subluxation in patients with post-stroke hemiplegia.

OBJECTIVE: To evaluate the ultrasonographic measurement of shoulder subluxation in patients with post-stroke hemiplegia. DESIGN: Prospective, single blind study. PATIENTS: A total of 41 patients with post-stroke hemiplegia were included (24 men and 17 women, mean age 56 years (standard deviation 11), age range 34-78 years). METHODS: Clinical evaluation of the affected shoulder was assessed using the Motricity Index scores and the Modified Ashworth Scale. Two ultrasonographic measurements were taken to check intra-rater reliability. The shoulder subluxation ratio was determined as the ratio of the radiographic vertical and horizontal distance, and the ultrasonographic lateral and anterior distances in the affected shoulder divided by that in the unaffected shoulder. RESULTS: Intraclass correlation coefficients of the repeated ultrasonographic lateral/anterior distance measurements in the unaffected and affected shoulders were 0.979/0.969 and 0.950/0.947, respectively. Ultrasonographic lateral/anterior distance ratios were negatively correlated with Motricity Index scores of the affected shoulder abduction (r = -0.490, p < 0.001/ r = -0.671, p < 0.001). Ultrasonographic anterior distance ratio was negatively correlated with Modified Ashworth Scale score of the affected shoulder (r = -0.374, p < 0.05). However, there was no correlation between radiographic distance ratios and clinical evaluation scores. CONCLUSION: We strongly recommend ultrasonography as a diagnostic tool to measure the degree of shoulder subluxation in patients with post-stroke hemiplegia.     

Advances in the evaluation and treatment of the infertile man

Numerous advances in technology have been made in the last several years in the diagnosis and treatment of the infertile man. Using case presentations, this article highlights these important new developments and reviews the basics of a comprehensive male infertility evaluation. The use of ultrasound as a critical, indispensable, yet noninvasive tool in the evaluation of possible male reproductive tract obstruction is discussed. Since assisted reproductive techniques (ARTs) have be come increasingly important in the management of the otherwise untreatable infertile man, specialized testing of sperm function, e.g., the sperm penetration assay (SPA), and strict morphology assessment are often useful prior to the initiation of some of these assisted reproductive procedures such as intrauterine insemination (IUI) or in vitro fertilization (IVF). Testicular touch preparation cytology and image analysis are also important additions to routine testicular biopsy for quantifying the extent of spermatogenesis. Finally, the revolutionary micromanipulation procedure of intracytoplasmic sperm injection (ICSI) has forever changed the practice of andrology by enabling men previously thought to be irreversibly infertile the chance to initiate their own biologic pregnancy.     

Possibility of correcting atherogenic dyslipoproteinemia by the mountain climate treatment]

Whether dyslipoproteinemias can be corrected with 24-day mountain therapy in a mid-mountainous area (the village of Malinovka, 1600 m above the sea-level) was studied in 225 males who had sustained large myocardial infarction. The posthospital rehabilitation of postinfarction patients in a mid-mountainous sanatorium caused a substantial change in blood lipoprotein composition, which were generally antiatherogenic. The antiatherogenic changes in blood lipoprotein composition retained within 10 months after their stay at the sanatorium, which indicates that mid-mountain climate is a promising tool for non-drug prevention and correction of atherogenic dyslipoproteinemias.     

Soft-tissue alterations associated with acute, extended open reduction and internal fixation or orbital fractures.

Soft-tissue alterations associated with radical degloving of the overlying soft tissues during extended open reduction and rigid internal fixation of facial fractures involving 51 orbits in 36 patients were studied. In all patients, the blepharoplasty skin muscle flap incision was employed in conjunction with, as necessary, a gingivobuccal sulcus and coronary incisions. Patients were evaluated between 6 and 20 months after surgery. Physical examination and standardized photographs were used for assessment. Ectropion developed in 2 lids (4%), and 10 lids (20%) had increased scleral show. Thirteen of the 51 lids (25%) revealed lateral canthal displacement; all 13 lids underwent canthal stripping. Cheek pad displacement developed in 8 patients (22%), all of whom had complete maxillary degloving without soft-tissue resuspension. No patient had frontal nerve palsy. Depression in the temporal area was noted in all patients in whom the temporalis was mobilized. Remote incisions and soft-tissue degloving used for extended open reduction and internal fixation are associated with morbidity that can be minimized by meticulous technique and soft-tissue repositioning at closure.     

A study on the hemodialysis period following cadaveric kidney transplantation--a comparison between two centers sharing cadaver donor kidney pairs

To study the hemodialysis period following cadaveric renal transplantation, we reviewed 18 consecutive cadaver donor kidney pairs of which one kidney was transplanted at Shiga University of Medical Science (SUMS) while the contralateral kidney was transplanted at Kyoto Prefectural Medical University (KPMU) between January 1983 and September 1988. Of these 18 pairs, graft function was satisfactory and the recipient was free from hemodialysis in 13 pairs. However, the postoperative hemodialysis periods were different between the two centers. To clarify the factors causing this difference, recipient factors, such as age, HLA matching, total ischemic time of the graft (TIT), immunosuppression, onset of diuresis and postoperative complications were studied. There were no significant differences in age, HLA matching, or immunosuppression. TIT of cases at SUMS was significantly longer than that of cases at KPMU. The postoperative hemodialysis period at SUMS was 25.8 days and that at KPMU was 17.8 days, however, the difference was not statistically significant. The results of this study indicate that TIT seems to be a major factor relating to delayed graft function in cadaveric renal transplantation.     

Role and regulation of interleukin-1 molecules in pro-asthmatic sensitised airway smooth muscle.

Interleukin (IL)-1beta is a pleiotropic, pro-inflammatory cytokine that has been importantly implicated in driving the inflammatory response and resultant changes in airway smooth muscle (ASM) responsiveness in asthma. IL-1beta belongs to a family of molecules, known as the IL-1 axis, which exert both pro- and anti-inflammatory effects. Since dysregulation of IL-1 axis molecules may be critical in the pathobiology of asthma, the present study examined the expression and activation of both the inhibitory and stimulatory IL-1 axis molecules in human ASM cells and their roles in modulating cytokine and immunoglobulin (Ig)E immune complex (IgE cx)-mediated changes in rabbit ASM constrictor and relaxant responsiveness. The results demonstrate the following. 1) Pre-treatment of isolated rabbit tracheal rings with the inhibitory IL-1 axis members, IL-1 receptor antagonist and IL-1 type-II receptor abrogated both IL-5- and IgE cx-induced changes in ASM responsiveness. 2) Administration of IL-5, IL-1beta and IgE cxs to human ASM cells increased mRNA and protein expressions of both stimulatory and inhibitory IL-1 axis molecules. 3) The time course of IL-5-induced IL-1 axis molecule expression preceded that of both IL-1beta and IgE immune cxs. Collectively, these findings suggest that modulation at the level of the interleukin-1 axis of molecules may have significant therapeutic potential in the treatment of asthma.     

Multiple internal resorptions in deciduous teeth: a case report

We report a case of rare multiple internal resorptions. Etiology of multiple internal resorptions is unknown. Interestingly, the patient had an atopic dermatitis, which is possibly related to multiple and rapid internal resorptions.     

Cervical Cancer with Paraaortic Metastases: Significance of Residual Paraaortic Disease after Surgical Staging

Cervical carcinoma frequently metastasizes to the paraaortic region, necessitating extended field radiotherapy to effect a cure. As imaging modalities are unreliable in identifying all cases of paraaortic nodal metastases (PAN), surgical staging is often utilized prior to radiotherapy. This study was aimed at identifying factors predictive of survival in women with cervical carcinoma and paraaortic metastases. In particular, survival based on extent of paraaortic disease was examined. The study group consisted of 43 women (stages IB–IVB) identified between 1982 and 1993 who were treated with extended field radiation for cervical carcinoma with histologically confirmed paraaortic metastases. The estimated 5-year survival for the study population was 24% with a median survival of 18 months. Pelvic tumor size had a significant impact on survival with the median survival being 34 months if the primary lesion was <6 cm compared to 14 months if ≥6 cm (P= 0.01). Eight of the 26 (31%) women without residual PAN disease after surgical staging remain alive and disease free (mean follow-up, 74 months). In contrast, only 1 of the 17 (6%) women with gross residual PAN is alive 71 months after treatment (P= 0.05). However, a comparison of Kaplan–Meier survival curves did not show a statistically significant advantage to the surgical excision of grossly involved PAN (P= 0.98). Although long-term survival among women with grossly involved, unresected paraaortic metastases is uncommon, further study is necessary to elucidate the role of surgical excision of bulky aortic disease in women with cervical cancer.     

Laparoscopic mobilization of the inferior epigastric artery for penile revascularization in vasculogenic impotence.

A laparoscopic approach was used for penile revascularization in a patient with vasculogenic impotence to avoid the long abdominal incision which was traditionally required to harvest the inferior epigastric artery as a neoarterial source. Despite the time-consuming nature of laparoscopy, this procedure was as efficacious but less morbid and required less convalescence than open revascularization. Whether more patients may benefit from this procedure must be evaluated in further studies.
