Extent of Pelvic Lymphadenectomy in Women With Squamous Cell Carcinoma of the Uterine Cervix: Is There Any Prognostic Value?

Background and Objectives: Some authors states that the removal of lymph node would only contribute towards assessing the lymph node status and regional disease control, without any benefit for the patients` survival. The aim of this paper was to assess the influence of the number of surgically dissected pelvic lymph nodes (PLN) on disease-free Survival. Methods: Retrospective cohort study on 42 women presenting squamous cell carcinoma (SCC) of the uterine cervix, with metastases in PLN treated by radical surgery. The Cox model was used to identify risk factors for recurrence. The model variables were adjusted for treatment-related factors (year of treatment, surgical margins and postoperative radiotherapy). The cutoff value for classifying the lymphadenectomy as comprehensive (15 PLN or more) or non-comprehensive (<15 PLN) was determined from analysis of the ROC curve. Results: Fourteen recurrences (32.6%) were recorded: three pelvic, eight distant, two both pelvic and distant, and one at an unknown location. The following risk factors for recurrence were identified: invasion of the deep third of the cervix and number of dissected lymph nodes <15. Conclusions: Deep invasion and non-comprehensive pelvic lymphadenectomy are possible risk factors for recurrence of SCC of the uterine cervix with metastases in PLN. J. Surg. Oncol. 2009;100:252-257.

One-stage laparoscopic bisegmentectomy 7-8 and bisegmentectomy 2-3 for bilateral colorectal liver metastases

Bisegmentectomy 7-8 is feasible even in the absence of a large inferior right hepatic vein. To our knowledge, this operation has never been performed by laparoscopy. This study was designed to present video of pure laparoscopic bisegmentectomy 7-8 and bisegmentectomy 2-3 in one-stage operation for bilateral liver metastasis. A 67-year-old man with metachronous bilobar colorectal liver metastasis was referred for surgical treatment after neoadjuvant chemotherapy. CT scan disclosed two liver metastases: one located between segments 7 and 8 and another one in segment 2. At liver examination, another metastasis was found on segment 3. We decided to perform a bisegmentectomy 7-8 along with bisegmentectomy 2-3 in a single procedure. The operation began with mobilization of the right liver with complete dissection of retrohepatic vena cava. Inferior right hepatic vein was absent. Right hepatic vein was dissected and encircled. Upper part of right liver, containing segment 7 and 8, was marked with cautery. Selective hemi-Pringle maneuver was performed and right hepatic vein was divided with stapler. At this point, liver rotation to the left allowed direct view and access to the superior aspect of the right liver. Liver transection was accomplished with harmonic scalpel and endoscopic stapling device. Bisegmentectomy 2-3 was performed using the intrahepatic Glissonian approach. The specimens were extracted through a suprapubic incision. Liver raw surfaces were reviewed for bleeding and bile leaks. Operative time was 240 minutes with no need for transfusion. Recovery was uneventful. Patient was discharged on the fifth postoperative day. Patient is well with no evidence of disease 14 months after liver resection. Tumor markers are within normal range. Bisegmentectomy 7-8 may increase resectability rate in patients with bilateral lesions. This operation can be performed safely by laparoscopy. Preservation of segments 5 and 6 permitted simultaneous resection of segments 2 and 3 with adequate liver remnant.

Bilateral lung transplantation in asymmetric thorax: Case reports

Suppurative lung diseases, such as cystic fibrosis and bronchiectasis, when diffuse and associated with important functional loss, can be treated with bilateral lung transplantation with good results. These diseases are frequently associated with previous lung resections presenting an asymmetric thorax, thus making lung extraction difficult and generating disproportion between the graft and the pleural cavity. To treat this condition, pneumonectomy and single lung transplantation is a feasible option; however, there are associated comorbidities and an invariable need for extracorporeal circulation. Described herein are 2 patients with an asymmetric thorax, treated with bilateral transplantation and lung volume reduction with lobectomy.

DETERMINATION OF ENERGY VALUE OF HAMBURGERS AND MEATBALLS BY DIRECT CALORIMETRY AND FOOD ANALYSIS COMPOSITION. COMPARISON WITH NUTRITION INFORMATION DISPLAYED ON PACKAGES

The nutritional composition found in the laboratory and those present on labels of manufactured foods can differ significantly. The purpose of this study was to determine the nutritional composition of hamburgers and meatballs and compare them with your labels. The food analysis was performed following the Analytical Standards Institute`s Adolfo Lutz and energy content was determined by bomb calorimetry. Regarding the energy value, all the samples had values less than informed on the label. The content of lipids of hamburgers and meatballs ( except the beef) were lower than those reported on the label. The values of protein for the meatballs and chicken hamburger had lower values than those labels. Thus, the labels may overestimate as underestimate some nutritional values, leading to population erroneous information.

Ictal technetium-99 m ethyl cysteinate dimer single-photon emission tomographic findings in epileptic patients with polymicrogyria syndromes: A Subtraction of ictal-interictal SPECT coregistered to MRI study

Purpose To describe the ictal technetium-99 m-ECD SPECT findings in polymicrogyria syndromes (PMG) during epileptic seizures. Methods We investigated 17 patients with PMG syndromes during presurgical workup, which included long-term video-electroencephalographic (EEG) monitoring, neurological and psychiatry assessments, invasive EEG, and the subtraction of ictal-interictal SPECT coregistered to magnetic resonance imaging (MRI) (SISCOM). Results The analysis of the PMG cortex, using SISCOM, revealed intense hyperperfusion in the polymicrogyric lesion during epileptic seizures in all patients. Interestingly, other localizing investigations showed heterogeneous findings. Twelve patients underwent epilepsy surgery, three achieved seizure-freedom, five have worthwhile improvement, and four patients remained unchanged. Conclusions Our study strongly suggests the involvement of PMG in seizure generation or early propagation. Both conventional ictal single-photon emission computed tomography (SPECT) and SISCOM appeared as the single contributive exam to suggest the localization of the epileptogenic zone. Despite the limited number of resective epilepsy surgery in our study (n=9), we found a strong prognostic role of SISCOM in predicting surgical outcome. This result may be of great value on surgical decision-making of whether or not the whole or part of the PMG lesion should be surgically resected.

Diagnostic value of interleukin-6 and C-reactive protein on early onset bacterial infection in preterm neonates with respiratory distress

Aims: To evaluate the C-reactive protein (CRP) and interleukin-6 (IL-6) as diagnostic tools for early onset infection in preterm infants with early respiratory distress (RD). Methods: CRP and IL-6 were quantified at identification of RD and 24 h after in 186 newborns. Effects of maternal hypertension, mode of delivery, Apgar score, birth weight, gestational age, mechanical ventilation, being small for gestational age (SGA), and the presence of infection were analyzed. Results: Forty-four infants were classified as infected, 42 as possibly infected, and 100 as uninfected. Serum levels of IL-6 (0 h), CRP (0 h), and CRP (24 h), but not IL-6 (24 h) were significantly higher in infected infants compared to the remaining groups. The best test for identification of infection was the combination of IL-6 (0 h) 36 pg/dL and/or CRP (24 h) 0.6 mg/dL, which yielded 93% sensitivity and 37% specificity. The presence of infection and vaginal delivery independently increased IL-6 (0 h), CRP (0 h) and CRP (24 h) levels. Being SGA also increased the CRP (24 h) levels. IL-6 (24 h) was independently increased by mechanical ventilation. Conclusions: The combination of IL-6 (0 h) and/or CRP (24 h) is helpful for excluding early onset infection in preterm infants with RD but the poor specificity limits its potential benefit as a diagnostic tool.

Progressive bilateral enophthalmos associated with cerebrospinal shunting

A 22-year-old woman was examined for a complaint of bilateral progressive enophthalmos that had begun after the cerebrospinal fluid shunting procedure 9 years ago. Photographs and CT scans taken before surgery proved that the position of her eyes was normal before surgery. The enophthalmos was so severe that it induced a poor eyelid-globe apposition with trichiasis and superficial keratopathy. CT of the orbits showed that both orbital roofs were arched and displaced toward the anterior cranial fossa. The placement of porous polyethylene sheets on the orbital roofs through a coronal approach corrected the eye position. A literature review indicated that cerebrospinal shuntings are plagued by a variety of complications including bone changes and craniosynostosis. We believe that enophthalmos associated with cerebrospinal fluid shunting results from a rare acquired bony orbital anomaly.

Keyhole sign: how specific is it for the diagnosis of posterior urethral valves?

Objectives Posterior urethral valves (PUV) are the most common cause of renal impairment in boys during early childhood. Although antenatal suspicion of this pathology has become quite common in recent years, prenatal diagnosis remains challenging. The aim of this study was to evaluate the predictive value of different ultrasound criteria currently used to diagnose PUV. Methods We reviewed the antenatal and postnatal files of 54 male patients referred to our center from 2000 to 2006 after detection of fetal bilateral hydronephrosis. The following ultrasound criteria were evaluated in relation to the postnatal diagnosis of P U V: amniotic fluid volume, bladder wall thickness, bladder dilatation and the presence of the `keyhole sign`. Results Forty-two fetuses (77.8%) were suspected to have PUV on prenatal examination. Out of these, 29 (69.0%) had PUV confirmed postnatally. The sensitivity and specificity of the antenatal diagnosis of PUV were 94% and 43%, respectively. Increased bladder wall thickness and bladder dilatation were highly associated with the diagnosis of PUV (P < 0.001). However, a thick-walled bladder was observed in 39.1% and a dilated bladder in 47.8% of the infants with a postnatal diagnosis other than PUV. The presence of the keyhole sign was not found to predict a diagnosis of PUV (P = 0.27). Conclusion In this series the use of classical prenatal ultrasound signs to diagnose PUV showed high sensitivity but low specificity. The best diagnostic indicators were increased bladder wall thickness and dilatation of the bladder. The keyhole sign was not found to be a reliable predictor of PUV. Copyright (C) 2009 ISUOG.

Bilateral sinus cysts in a filly treated by endoscopic sinus surgery

Bilateral cysts in the frontal and caudal maxillary sinuses in a filly created by endoscopic Sinus surgery, (sinoscopy) and triangulation technique are described. Sinoscopy has the advantage of being a minimally invasive technique and permits a complete inspection of the frontal and maxillary sinuses, which is not possible through flap sinusotomy.

Recurrent bilateral gingival peripheral calcifying epithelial odontogenic tumor (Pindborg tumor): A case report

Calcifying epithelial odontogenic tumor (CEOT) is an extremely rare, benign neoplasm, accounting for approximately 1% of all odontogenic tumors. Peripheral CEOTs commonly resemble oral hyperplastic or reactive lesions and are histologically similar to their intraosseous counterparts. We report an unusual case of multifocal peripheral CEOT. A 40-year-old female presented with bilateral soft, painful, erythematous, gingival swellings localized in premolar areas of the mandibular gingiva. The presumptive diagnosis was bilateral pyogenic granuloma. The masses were surgically excised under local anesthesia without bone curettage and both recurred 12 months later. Morphologic features, and histochemical and immunohistochemical tests revealed bilateral peripheral calcifying odontogenic epithelial tumor. There is no clinical or radiographic evidence of recurrence 3.5 years after excision. This multifocal phenomenon has been reported previously only for intraosseous CEOT. Gingival masses must be carefully evaluated for clinical and histologic evidence of neoplasia. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 108: e66-e71)

Congenital Bilateral Perisylvian Syndrome: Familial Occurrence, Clinical and Psycholinguistic Aspects Correlated with MRI

Objective: Congenital bilateral perisylvian syndrome (CBPS) is frequently caused by polymicrogyria (PMG). The aim of this study was to correlate the clinical and psycholinguistic aspects with neuroradiological data of patients with CBPS. Methods: Thirty-one patients were studied. We performed a clinical investigation of the patients and their families, including MRI scanning, neuropsychological tests and language evaluation. Results: The statistical analysis showed that: a) prenatal events are associated with the non-familial type of PMG; b) diffuse PMG is associated with pseudobulbar signs, as opposed to BPPP; c) motor deficit is associated with diffuse PMG; d) epilepsy is equally present in patients with both familial or non-familial PMG, but is more frequently seen in patients with diffuse PMG; e) dyslexia and SLI can be a feature of both the diffuse or BPPP, and either familial or sporadic cases of PMG. Conclusions: The severity of clinical manifestations in CBPS is correlated with the extent of cortical involvement. Most patients with CBPS have a history of speech delay or language difficulties and no epilepsy. Dyslexia can be found in patients with PMG.

A new candidate locus for bilateral perisylvian polymicrogyria mapped on chromosome Xq27

Polymicrogyria (PMG) is characterized by an excessive number of small and prominent brain gyri, separated by shallow sulci. Bilateral perisylvian polymicrogyria (BPP) is the most common form of PMG. Clinical signs include pseudobulbar paresis, mental retardation, and epilepsy. Familial forms of BPP have been described and a candidate locus was previously mapped to chromosome Xq28, distal do marker DXS8103. The objective of this study was to perform linkage analysis in one family segregating BPP. A total of 15 individuals, including 8 affected patients with BPP were evaluated. Family members were examined by a neurologist and subjected to magnetic resonance imaging scans. Individuals were genotyped for 18 microsatellite markers, flanking a 42.3 cM interval on ch Xq27-q28. Two-point and multipoint linkage analysis was performed using the LINKAGE package and haplotype reconstruction was performed by GENEHUNTER software. Our results showed a wide spectrum of clinical manifestations in affected individuals with BPP, ranging from normal to mild neurological abnormalities. Two-point linkage analysis yield a Zmax=2.06 at theta=0.00 for markers DXS1205 and DXS1227. Multipoint lod-scores indicate a candidate interval of 13 cM between markers DSXS1205 and DXS8043, on ch Xq27.2-Xq27.3. These results point to a new locus for BPP in a more centromeric location than previously reported. (C) 2008 Wiley-Liss, Inc.

Palpation of the lateral pterygoid area in the myofascial pain diagnosis

Objectives. To evaluate the diagnostic value of intraoral palpation at the lateral pterygoid (LP) area as part of the physical examination to detect myofascial pain, according to modified research diagnostic criteria for temporomandibular disorders. Study design. Fouty-four women composed the myofascial pain group, and 33 symptom-free age-matched were the control group. One examiner calibrated and blinded to group distribution performed 2 intraoral bilateral palpations of the lateral pterygoid. Results. The LP area palpation showed sensitivity and specificity values of 79.55% and 77.27%, respectively, and positive and negative likelihood ratios of 3.50 and 0.26, respectively. Conclusions. Palpation at the LP area did not reach acceptable values of specificity, and care must be taken when judging positive response to this procedure.
