The Tessier Number 5 Facial Cleft: Surgical Strategies and Outcomes in Six Patients

The Tessier no. 5 facial cleft is an extremely rare congenital malformation. Only 26 cases have been described In the English-language literature. The cleft begins In the upper lip just medial to the oral commissure, extending across the cheek as a groove ending at the junction of the middle and lateral thirds of the lower eyelid. The bone Involvement usually Includes an alveolar cleft in the premolar region, extends across the maxilla lateral to the Infraorbital nerve, up to the infraorbital rim and orbital floor. The goals of the surgical procedure Include reconstructing the lower eyelid, repositioning the lateral canthus, closure of the labiomaxillary cleft, and restoration of the skeletal continuity (including the orbital floor defect) with bone grafts. We present six patients with the Tessier no. 5 facial cleft who have been treated in our combined centers and discuss the surgical options and difficulties faced in the reconstruction of this rare and challenging craniofacial malformation. To date, we have treated six patients (two with bilateral and four with unilateral clefts). Three of the patients with unilateral clefting had an associated no. 4 cleft and one patient with a bilateral cleft had an associated no. 3 cleft. This paper represents the largest series to date documenting surgery for patients with the Tessier no. 5 facial cleft.

Effect of the bilateral hip bone density measurement on clinical practice in elderly subjects

Objectives: The aim of this study was to determine whether the addition of the measurement of bilateral hip bone mineral density (BMD) has an impact on indications for osteoporosis (OP) treatment in community-dwelling elderly individuals, based on criteria from the National Osteoporosis Foundation (NOF). Methods: In total, 605 consecutive community-dwelling elderly individuals who were 65 years and older were evaluated. Dual energy X-ray absorptiometry was used to determine the lowest T-score in the lumbar spine + unilateral hip, the bilateral hips, and the lumbar spine + bilateral hips. Risk factors associated with the lowest T-score in these three conditions were applied to indicate treatment in accordance with NOF criteria. McNemar`s test was used to assess the difference of adding bilateral hip BMD measurements. Results: There was a significant difference in the frequency of pharmacological indication using NOF criteria together with the lowest T-score for the three tests (72.8% for lumbar spine + bilateral hips and 71.2% for lumbar spine + unilateral hip; p=0.002). A higher frequency of treatment indication was also observed for lumbar spine + unilateral hip (71.2%) compared to bilateral hips (61.1%) (p<0.001). The discrepancies in treatment appeared to be more evident in women when analyzed by gender distribution. Conclusion: Our finding supports the theory that evaluation of the bilateral hips with the lumbar spine seems to be more sensitive measure for identifying patients with an osteoporosis treatment indication. Furthermore, despite the well-known artifact in the lumbar spine, this site should not be excluded when determining the indication for OP treatment in elderly people. (C) 2009 Elsevier Ireland Ltd.

Laparoscopic right hemihepatectomy for hepatolithiasis

Background Liver resection is the definitive treatment for unilateral hepatolithiasis [1]. Recently, laparoscopic major hepatectomias have become more common and are being performed in highly specialized centers [2-4]. However, few laparoscopic liver resections for hepatolithiasis have been reported. Chen et al. [5] reported two cases of laparoscopic left lobectomy for hepatolithiasis, but to our knowledge, right hepatectomy has never been reported to date. This video demonstrates technical aspects of a totally laparoscopic right hepatectomy in a patient with hepatolithiasis. Methods A 21-year-old woman with right-sided nonoriental primary intrahepatic stones [1] was referred for surgical treatment. The operation followed four distinct phases: liver mobilization, dissection of the right portal vein and right hepatic artery, extrahepatic dissection of the right hepatic vein, and parenchymal transection with harmonic shears and linear staplers for division of segment 5 and 8 branches of the middle hepatic vein. No Pringles` maneuver was used. In contrast to liver resection for other indications, the right bile duct was enlarged and filled with stones. It was divided during parenchymal transection and left open. After removal of the surgical specimen, the biliary tree was flushed with saline until stone clearance, under radioscopic surveillance, was complete. The right hepatic duct then was closed with running suture. Results The operative time was 240 min, and the estimated blood loss was 120 ml, with no blood transfusion. The hospital stay was 5 days. At this writing, the patient is well and asymptomatic 7 months after the procedure. Conclusion Laparoscopic liver resection is safe and feasible for patients with hepatolithiasis and should be considered for those suffering from intrahepatic stones.

A premenopausal woman with virilization secondary to an ovarian Leydig cell tumor

Background. A 33-year-old woman presented to an endocrinology clinic with a 5-year history of secondary amenorrhea. 2 years before presentation, she had noticed progressively worsening signs of virilization. Investigations. Measurement of levels of serum free and total testosterone, androstenedione, dehydroepiandrosterone sulfate and gonadotropins; transvaginal ultrasonography, abdominal and pelvic MRI and (18)F-fluorodeoxyglucose PET imaging. Diagnosis. Virilization secondary to an ovarian Leydig cell tumor. Management. The patient underwent a left salpingo-oophorectomy that confirmed the diagnosis of a unilateral Leydig cell tumor. Complete normalization of androgens and gonadotropin levels was achieved after surgery.

A better understanding of urogenital tuberculosis pathophysiology based on radiological findings

Purpose: To assess the radiological findings of urogenital tuberculosis (UGT) in patients at different disease stages, for a better understanding of its pathophysiology. Patients and methods: We retrospectively reviewed the radiological exams of 20 men (median age 41 years; range: 28-65) with urogenital tuberculosis diagnosis. The patients were classified in the following groups: (1) bilateral renal tuberculosis with predominantly parenchymatous involvement; (2) unilateral renal tuberculosis; (3) unilateral renal tuberculosis with bladder tuberculosis and (4) bilateral renal tuberculosis with bladder tuberculosis. Results: One AIDS patient had multiple bilateral renal tuberculosis abscesses (group 1). Six patients had unilateral renal tuberculosis with hydronephrosis due to stenosis and thickening of the collecting system, without involvement of the bladder or contralateral kidney (group 2). Six patients had bladder tuberculosis with diffuse thickening of the bladder wall, with one very low or no function kidney while the other kidney was normal (group 3). Seven patients had bladder tuberculosis associated to a very low or no function kidney with the other kidney with high-grade vesicoureteral reflux-associated ureterohydronephrosis (group 4). In two patients, sequential exams showed evolution of tuberculosis from a unilateral renal and ureteral lesion to contracted bladder and dilatation of the contralateral kidney secondary to high-grade reflux. Conclusions: UGT may have variable radiological presentations. However, in two of our cases we have seen that tuberculosis involvement of the urinary tract may be sequential. Further evidences are necessary to confirm this hypothesis. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

Cytokine Profile in Pleural Fluid and Serum After Lung Transplantation

Background. Lung transplantation is the procedure of choice in several end-stage lung diseases. Despite improvements in surgical techniques and immunosuppression, early postoperative complications occur frequently. Objective. To evaluate the pleural inflammatory response after surgery. Patients and Methods. Twenty patients aged 18 to 63 years underwent unilateral or bilateral lung transplantation between August 2006 and March 2008. Proinflammatory cytokines interleukin (IL)-1 beta, IL-6, and IL-8 and vascular endothelial growth factor in pleural fluid and serum were analyzed. For cytokine evaluation, 20-mL samples of pleural fluid and blood (right, left, or both chest cavities) were obtained at 6 hours after surgery and daily until removal of the chest tube or for a maximum of 10 days. Data were analyzed using analysis of variance followed by the Holm-Sidak test. Results. All effusions were exudates according to Light`s criteria. Pleural fluid cytokine concentrations were highest at 6 hours after surgery. Serum concentrations were lower than those in pleural fluid, and IL-1 beta, IL-6, and IL-8 were undetectable at all time points. Conclusions. There is a peak concentration of inflammatory cytokines in the first 6 hours after transplantation, probably reflecting the effects of surgical manipulation. The decrease observed from postoperative day 1 and thereafter suggests the action of the immunosuppression agents and a temporal reduction in pleural inflammation.

Malformations of the index nails

We report a 52-year-old woman with micronychia of the index fingers. Radiographic examination revealed a Y-shaped bifurcation of the distal phalanx of both index fingers. She was diagnosed with congenital onychodysplasia of the index fingers (COIF) or Iso-Kikuchi syndrome. COIF is a rare condition characterized by a variety of nail dysplasia of the index fingers. Five criteria characterize COIF: congenital occurrence, unilateral or bilateral index finger involvement, variability in nail appearance, hereditary involvement and frequently associated bone abnormalities. Micronychia, polyonychia, anonychia, hemionychrogryphosis and malalignment are the observed index finger defects. Most cases have been described in Japan, and to our knowledge, this is the first case of COIF reported in South America.

Pulmonary involvement in pleural tuberculosis: How often does it mean disease activity?

Objective: To evaluate in chest X-rays and high-resolution computed tomographies of patients with pleural tuberculosis, the incidence of parenchymal and mediastinal lung lesions suggestive of active disease. Methods: Prospective study (2008-2009) evaluating the radiographic and tomographic abnormalities of 88 HIV-negative patients with pleural tuberculosis (unilateral effusion). The images were reviewed by 3 independent specialists, and the observed changes were classified according to previously established criteria: presence or absence of signs suggestive of disease activity, and nonspecific findings. Results: Abnormal changes were observed in chest X-rays of 22 (25%) patients and in the computed tomography of 55 (63%). Images compatible with active pulmonary tuberculosis were detected by radiography in 9 (10%) patients and by tomography in 38 (43%). Only 4 (4.5%) patients had tomography images suggestive of residual disease. Conclusion: The present study demonstrates that pulmonary involvement is quite common in pleural tuberculosis. This finding is mainly observed in high-resolution computed tomography and has important epidemiological implications, since patients with pleural tuberculosis are significant sources of infection and disease dissemination.

Comparative study of Botox (R) injection treatment for upper eyelid retraction with 6-month follow-up in patients with thyroid eye disease in the congestive or fibrotic stage

Aim To compare morphometric data of the eyelid fissure and the levator muscle function (LF) before and up to 6 months after transcutaneous injection with five units of Botox (R) in patients with upper lid retraction (ULR) from congestive or fibrotic thyroid eye disease (TED). Methods Twenty-four patients with ULR from TED were submitted to transcutaneous injection of 5 units (0.1 ml) of Botox in one eye only. Patients were divided into two groups: 12 with congestive-stage TED (CG), and 12 with fibrotic-stage TED (FG). Bilateral lid fissure measurements using digital imaging and computer-aided analysis were taken at baseline and at regular intervals 2 weeks, 1 month, 3 months and 6 months after unilateral Botox injection. Mean values taken at different follow-up points were compared for the two groups. Results Most patients experienced marked improvement in ULR, with a mean reduction of 3.81 mm in FG and 3.05 mm in CG. The upper eyelid margin reflex distance, fissure height and total area of exposed interpalpebral fissure were significantly smaller during 1 month in CG and during 3 months in FG. Reduction in LF and in the difference between lateral and medial lid fissure measurements was observed in both groups. The treatment lasted significantly longer in FG than in CG. Conclusions A single 5-unit Botox injection improved ULR, reduced LF and produced an adequate lid contour in patients with congestive or fibrotic TED. The effect lasts longer in patients with fibrotic orbitopathy than in patients with congestive orbitopathy.

Improvements in the 6-Min Walk Test and Spirometry Following Thoracentesis for Symptomatic Pleural Effusions

Background: Impairment in pulmonary capacity due to pleural effusion compromises daily activity. Removal of fluid improves symptoms, but the impact, especially on exercise capacity, has not been determined. Methods: Twenty-five patients with unilateral pleural effusion documented by chest radiograph were included. The 6-min walk test, Borg modified dyspnea score, FVC, and FEV, were analyzed before and 48 h after the removal of large pleural effusions. Results: The mean fluid removed was 1,564 +/- 695 mL. After the procedure, values of FVC, FEV and 6-min walk distance increased (P<.001), whereas dyspnea decreased (P<.001). Statistical correlations (P<.001) between 6-min walk distance and FVC (r=0.725) and between 6-min walk distance and FEV, (r=0.661) were observed. Correlations also were observed between the deltas (prethoracentesis X postthoracentesis) of the 6-min walk test and the percentage of FVC (r=0.450) and of FEV, (r=0.472) divided by the volume of fluid removed (P<.05). Conclusion: In addition to the improvement in lung function after thoracentesis, the benefits of fluid removal are more evident in situations of exertion, allowing better readaptation of patients to routine activities.

Epidemiology of urogenital tuberculosis worldwide

Objectives: To characterize the epidemiology of urogenital tuberculosis worldwide and to compare the features of patients from developing countries to those from developed countries. Methods: A comprehensive search of articles published up to April 2008 using a combination of the terms `tuberculosis`, `genitourinary`, `renal` and `urogenital` was performed. Results: Urogenital tuberculosis affects more men than women (2:1), with a mean age of 40.7 years (range 5-90). In 26.9% of cases there is a non-functioning unilateral kidney and in 7.4%, renal failure. Patients from developing countries are more likely to have a delayed diagnosis with a higher frequency of renal failure, unilateral non-functioning kidney, ablative surgery and contracted bladder. Conclusions: Urogenital tuberculosis is a worldwide disease with more destructive behavior in developing countries where urgent strategies for early detection are particularly warranted.

Bronchial Complications Following Lung Transplantation

Introduction. Bronchial complications owing to the airway anastomosis in lung transplantation are important causes of morbidity and mortality. They occur in up to 27% of cases as defined by stenosis, necrosis, and dehiscence. Treatment depends on the type of complication. Objective. To report our experience to treat this complication. Methods. Between 2000 and 2007, we performed 71 lung transplants of which 36 were bilateral. The total number of anastomoses was 107:52 to the right and 55 to the left. The telescoping technique was initially used (14 initial unilateral transplants), and after October, 2003 it was changed to an end-to-end anastomosis (57 transplants and 93 anastomoses). Results. Eight patients developed bronchial complications including two that were bilateral. There were 4 stenosis, 3 dehiscences, and 3 necrosis complications (9.4%). The complication rate for telescoping anastomosis was 21.4%, and for the end-to-end technique, 7.5%. The treatment of the stenosis used metallic or plastic self-expandable stents. Two bronchial dehiscences resulted in case of bronchopleural fistulae, empyema, and death; the other patient experienced spontaneous resolution. Concerning bronchial necrosis, I patient developed fistulization to the pulmonary artery and massive hemoptysis, and the other with bilateral necrosis, a spontaneous resolution. Conclusion. Our bronchial anastomosis complication rate was comparable with that in other reports. The rate for the telescoping technique was greater compared with the end-to-end technique. The treatment of bronchial stenosis with a self-expandable prosthesis showed good results.

Cervical Mobility in Women With Migraine

Objective.-To contrast the cervical range of motion (CROM) in women with episodic migraine (EM), transformed migraine (TM), and controls without migraine headaches. Background.-Migraineurs often complain about neck pain. Furthermore, neck problems can worsen the headaches in individuals with migraine. Individuals with neck pain usually have reduced CROM. Nonetheless, studies assessing the CROM in migraineurs are scarce. Methods.-Our sample was selected in an outpatient headache clinic, and consisted of 45 women aged 20-54 years old, 15 per group. Cervical mobility was evaluated in movements of flexion, extension, right lateral flexion, left lateral flexion, right rotation, and left rotation using the CROM technique, and was contrasted among the groups. Migraine clinical patterns were also evaluated ( frequency, duration of migraine, pain in the moment of evaluation, pain in movement, and pain localization) as a function of CROM. Results.-Compared with controls, individuals with TM had numerically inferior CROM in all parameters, and significant reduction in 3 of them: extension (59.3 vs 68.1, P = .02), left lateral flexion (44.5 vs 49.1, P = .03), and right rotation (62.2 vs 69.6, P = .02). Compared with individuals with migraine, the TM group presented significantly reduced mobility only for extension ( 59.3 vs 68.4, P = .02). Migraineurs also had numerically inferior ROM, contrasted to controls, in 5 of the 6 parameters, although significance was seen just for right rotation (60.8 vs 68.6 P < .01). There was no correlation between cervical mobility and migraine parameters. The CROM was not reduced for the symptomatic side of migraine, in cases of unilateral pain. Conclusion.-Contrasted to controls, individuals with episodic and TM have decreased cervical range of motion.

Additional sensory information reduces body sway of individuals with anterior cruciate ligament injury

The purpose of this study was to investigate whether the additional sensory information could improve postural control in individuals with unilateral anterior cruciate ligament (ACL) injury. Twenty-eight individuals with unilateral ACL injury (mean age 23.6, 26 males, 2 females) and 28 healthy young control subjects (mean age 22.1 years, 26 males, 2 females) participated in this study. Postural control was evaluated with subjects single-leg standing on a force platform with eyes closed under two sensory conditions: normal sensory information and light touch to a stationary bar (applied force below 1 N). Three trials of 30 5 were performed in each single-leg stance and in each sensory condition. Mean sway amplitude and predominant frequency of center of pressure were calculated for both anterior-posterior and medial-lateral directions. Individuals with ACL injury showed greater mean sway amplitude than healthy control individuals even though the predominant frequency was similar for both groups. Additional sensory information improved postural control performance in individuals with ACL injury and healthy control, with a greater effect observed for the ACL group. Based on these results, we suggest that reduction in postural control performance in individuals with ACL injury would be due to the reduction of sensory information provided by the ACL, but when sensory information is enhanced, postural control performance improves. These results have implications for novel approaches to improve stability in individuals with ACL injury. (c) 2008 Elsevier Ireland Ltd. All rights reserved.

Non-N-Methyl-D-Aspartate Glutamate Receptors in the Paraventricular Nucleus of Hypothalamus Mediate the Pressor Response Evoked by Noradrenaline Microinjected Into the Lateral Septal Area in Rats

The lateral septal area (LSA) is a part of the limbic system and is involved in cardiovascular modulation. We previously reported that microinjection of noradrenaline (NA) into the LSA of unanesthetized rats caused pressor responses that are mediated by acute vasopressin release. Magnocellular neurons of the paraventricular (PVN) and supraoptic (SON) of the hypothalamus synthesize vasopressin. In the present work, we studied which of these nuclei is involved in the pressor pathway activated by unilateral NA injection into the LSA as well as the local neurotransmitter involved. Chemical ablation of the SON by unilateral injection of the nonspecific synapses blocker cobalt chloride (1 mM/100 nl) did not affect the pressor response evoked by NA (21 nmol/200 nl) microinjection into the LSA. However, the response to NA was blocked when cobalt chloride (1 mM/100 nl) was microinjected into the PVN, indicating that this hypothalamic nucleus is responsible for the mediation of the pressor response. There is evidence in the literature pointing to glutamate as a putative neurotransmitter activating magnocellular neurons. Pretreatment of the PVN with the selective non-N-methyl-D-asparate (NMDA) antagonist NBQX (2 nmol/100 nl) blocked the pressor response to NA microinjected into the LSA, whereas pretreatment with the selective NMDA antagonist LY235959 (2 nmol/100 nl) did not affect the response to NA. Our results implicate the PVN as the final structure in the pressor pathway activated by the microinjection of NA into the LSA. They also indicate that local glutamatergic synapses and non-NMDA glutamatergic receptors mediate the response in the PVN. (c) 2008 Wiley-Liss, Inc.
