RESUMO

Due to the high risk of morbidity and mortality from unrecognized and untreated pre-eclampsia, clinicians should have a high index of suspicion to evaluate, treat and monitor patients presenting with signs concerning for pre-eclampsia. Early blood pressure management and seizure prophylaxis during labor are critical for maternal safety. Intrapartum, special anesthetic considerations should be employed to ensure the safety of the parturient and fetus. Patients who have pre-eclampsia should be aware that they are at high risk for the future development of cardiovascular disease.

RESUMO

BACKGROUND: Analysis of systematic 12-core biopsies (SBx) has shown that African-American (AA) men tend to harbor higher risk prostate cancer (PCa) at presentation relative to other races. Multiparametric magnetic resonance imaging (mpMRI) and MRI-ultrasound fusion-guided biopsy (FBx) have been shown to diagnose more intermediate- and high-risk PCa in the general population; however, the efficacy in AA remains largely uncharacterized. We aim to evaluate the utility of FBx in an AA patient cohort. METHODS: Men suspected of PCa underwent an mpMRI and FBx with concurrent SBx from 2007 to 2015 in this institutional review board-approved prospective cohort study. Patient demographics, imaging and fusion biopsy variables were collected. χ2, Mann-Whitney U-test and McNemar's tests were performed to compare proportions, means and paired variables, respectively. Clinically significant PCa (CSPCa) was defined as Gleason score ⩾3+4. RESULTS: Fusion biopsy demonstrated exact agreement with SBx risk categories in 64% of AA men. There was no statistically significant difference in the detection of CSPCa between FBx vs SBx (68 vs 62 cases, P=0.36). However, FBx detected 41% fewer cases of clinically insignificant PCa (CIPCa) compared with SBx (FBx 30 vs SBx 51 cases, P=0.0004). The combined FBx/SBx biopsy approach detected significantly more cases of CSPCa (FBx/SBx 80 vs SBx 62 cases, P=0.004) while detecting comparable number of cases of CIPCa (FBx/SBx 45 vs SBx 51 cases, P=0.37) compared with SBx alone. FBx/SBx also detected more CSPCa in patients with a history of prior negative SBx (FBx/SBx 28 vs 19 cases, P=0.003). CONCLUSIONS: FBx when used in combination with SBx detected more cases of CSPCa while not significantly increasing the diagnosis of CIPCa in AA men. Future multicenter studies will be needed to validate ultimately the clinical implications of FBx in AA patients.

RESUMO

BACKGROUND: The Prostate Cancer Prevention Trial Risk Calculator 2.0 (PCPTRC) is a widely used risk-based calculator used to assess a man's risk of prostate cancer (PCa) before biopsy. This risk calculator was created from data of a patient cohort undergoing a 6-core sextant biopsy, and subsequently validated in men undergoing 12-core systematic biopsy (SBx). The accuracy of the PCPTRC has not been studied in patients undergoing magnetic resonance imaging/ultrasound (MRI/US) fusion-guided biopsy (FBx). We sought to assess the performance of the PCPTRC for straitifying PCa risk in a FBx cohort. METHODS: A review of a prospective cohort undergoing MRI and FBx/SBx was conducted. Data from consecutive FBx/SBx were collected between August 2007 and February 2014, and PCPTRC scores using the PCPTRC2.0R-code were calculated. The risk of positive biopsy and high-grade cancer (Gleason ⩾7) on biopsy was calculated and compared with overall and high-grade cancer detection rates (CDRs). Receiver operating characteristic curves were generated and the areas under the curves (AUCs) were compared using DeLong's test. RESULTS: Of 595 men included in the study, PCa was detected in 39% (232) by SBx compared with 48% (287) on combined FBx/SBx biopsy. The PCPTRC AUCs for the CDR were similar (P=0.70) for SBx (0.69) and combined biopsy (0.70). For high-grade disease, AUCs for SBx (0.71) and combined biopsy (0.70) were slightly higher, but were not statistically different (P=0.55). CONCLUSIONS: In an MRI-screened population of men undergoing FBx, PCPTRC continues to represent a practical method of accurately stratifying PCa risk.

RESUMO

Meconium obstruction of prematurity is an entity primarily affecting very low birthweight or extremely low birthweight babies causing low intestinal obstruction. Its presence may at best delay establishment of enteral feeding and compromise nutrition and at worst lead to mechanical obstruction requiring surgery or to intestinal perforation. There are considerable challenges in the recognition, diagnosis and management of this condition. Awareness of the disease and understanding of its pathogenesis may lead to early detection of affected babies and allow proactive measures to decrease the associated morbidity and mortality.

RESUMO

INTRODUCTION: Controversy persists regarding ideal management strategies in well-differentiated thyroid cancers (WDTC). This retrospective study reviews the utilization of a modified AMES risk stratification in the management of our institution's patients. METHODS: A total of 352 patients (median follow-up of 5.5 years) were reviewed and were risk stratified. Surgical resection was performed, and patients with clinically palpable lymph nodes were subjected to radical neck dissection. Patients were referred for adjuvant therapy if necessary. RESULTS: Of the 352 patients, 264 (75%) were females and 276 (78%) had papillary thyroid cancer (PTC). For those with lymph nodes (50%), 95% had PTC. In this series, 72% of the patients underwent total thyroidectomy; 5-year disease-free survival probability was 100% in low-risk patients, 92% in intermediate-risk patients, and 64% in high-risk patients. The 5-year overall survival probability was 100% in low-risk patients, 96% in intermediate-risk patients, and 69% in high-risk patients, respectively (both logrank trend p<0.001). CONCLUSIONS: Management of WDTC requires multimodal treatment and should be based on patient risk classifications. We recommend aggressive surgical resection for all gross disease in high-risk and intermediate-risk patients. Adjuvant therapy is recommended in high-risk patients, but should be individualized for intermediate-risk patients. Total thyroidectomy may not be necessary in low-risk patients.

RESUMO

AIM: Few retrospective studies have evaluated infants with hypertrophic pyloric stenosis (HPS) for associated urological anomalies. They have led to contradictory conclusions. The aim of this study was to evaluate the incidence of urinary tract anomalies in infants with HPS and to establish the clinical significance of this association. METHODS: One hundred and twenty-two infants (100 boys) who underwent pyloromyotomy between 1992 and 2002 were prospectively evaluated. Screening ultrasound (Us) of the urinary tract was performed in 107 infants, while 15 did not attend their ultrasound appointment. RESULTS: Renal ultrasound was abnormal in 4 (4%) of 107 screened patients with HPS. Three patients were found to have mild hydronephrosis and, in one patient, a small, normal kidney was detected. Two patients with hydronephrosis had Us follow-up and the third patient underwent Tc-99 mercaptoacetyl triglycine (MAG 3) scan. In all three patients, the hydronephrosis resolved completely on follow-up scan. CONCLUSION: The incidence of abnormal renal ultrasound in children with HPS is similar to the reported incidence of 3-6% determined with routine ultrasound screening of healthy newborns. The abnormalities detected were not clinically relevant and did not require surgical intervention. We do not recommend screening of the urinary tract in infants with HPS.

RESUMO

In vivo intracerebral microdialysis is an important neurochemical technique that has been used extensively in the experimental setting. Relatively recently, techniques have been developed to utilize this method in human subjects. The past decade has seen the advent of clinical investigations utilizing in vivo microdialysis in a number of neuropathological states. This review summarizes the principles of in vivo microdialysis techniques, as applied to humans, while discussing the significance of recent investigations for future clinical development.

RESUMO

Lactoferrin is an iron-binding protein found in human mucosal secretions such as milk. A variety of functions have been ascribed to this protein, it appears to contribute to antimicrobial host defense. Still its overall physiological role remains to be defined. We sought to study the role of recombinant human lactoferrin (rhLf) in Shigella infection. Invasion of epithelial cells is essential to the development of bacillary dysentery. Shigella flexneri 5 M90T, a virulent strain, was evaluated in the classic HeLa cell invasion model, in immunoblots, and by transmission electron microscopy, immunofluorescence, and deconvolved microscopy Bacteria not exposed to rhLf were used as controls. We found that rhLf decreased significantly the invasiveness of S. flexneri 5 M90T in a HeLa cell model. The immunoblot data showed that invasion plasmid antigen B (IpaB) was released from the bacteria during incubation with rhLf. Lactoferrin treatment did not directly dissociate the complex of IpaB and IpaC (IpaBC) once the complex had been formed. Furthermore, ferric iron had no effect on release of IpaB. Electron microscopy of rhLf-treated bacteria suggested a reduction in vacuolization of the HeLa cell cytoplasm and decreased number of bacteria within HeLa cells. At 40,000 x magnification the few rhLf-treated Shigella that invaded exhibited a dense ring completely surrounding them. Immunofluorescence and deconvolved microscopy suggested that rhLf-treated bacteria were completely surrounded by a thick layer of actin. The fact that two cell surface functions (invasion and actin-mediated movement) were deranged suggests that rhLf disrupts the integrity of the bacterial outer membrane in which virulence proteins are anchored. The mechanism by which rhLf impairs Shigella invasiveness may be relevant to other enteropathogens that share similar virulence strategies.

RESUMO

Jarab (Scabies) is an itchy dermatosis caused by human mite Sarcotes scabiei. It usually involves inter digital spaces of hands and the flexor surface of the wrists. In severe infection, the dorsal surface of the elbows, anterior axillary folds, female breasts, periumblical area, genital area and buttocks are involved. Night itching in particular and secondary infection with postulation and lichenification in general are the main clinical features.According to Greeco-Arabian concept, conversion of Khilt-e Dam (Blood)into Khilt-e-Sauda, or increased ratio of Khilt-e-Safra in blood or when blood combined with Balgham-e -Share called Fasad-e Dam and this Fasad-e-Dam (Abnormal blood) acts as a culture media for Ajsam-e- Kahabeesa (Pathogenic organisms). Fasad-e Dam along with bacterial invasion, is collectively called Maddah-al - Jarab b Unani philosophers, later which was identified as sarcoptes scabiel and its infection is termed as scabies, The unani treatment of Jarab include Musaffiat-e-Dam (Blood purifiers) and Munzijat Wa Mukhrijat-e-Khilt (Coctive and expulsive of abnormal humour) drugs system cally and Maan-e-Ufoomat (Antiseptics) and Daaf-e-Jaraseem (Antimicrobials) drugs locally. Among useful unani drugs, karela powder showed relief in symptoms upto and average 53% of cases as our stud include 30 cases including control group of ten cases of 15 days treatment.

RESUMO

Because topiramate (TPM) suppresses voltage-sensitive Na+ channels and non-N-methyl-D-aspartate (NMDA) receptors and enhances gamma-aminobutyric acid (GABA)-mediated inhibition, we tested whether it would protect against cerebral ischemia. The right middle cerebral artery (MCA) was embolized by an intra-arterial injection of autogenous thrombus. Two hours after thrombus injection, animals received intra-peritoneal injections (i.p.) of normal saline as control (n=6) or alternatively, a low- (20 mg/kg, i.p., n=6) or high-dose (40 mg/kg, i.p., n=6) of TPM. Neurological deficit was scored at 2 h and 24 h following the ischemic insult. The animals were sacrificed 24 h after ischemia and the coronal brain sections were stained with 2% 2,3,5-triphenyltetrazolium chloride (TTC) for determination of the percentage of infarct volume. Administration of TPM significantly improved the 24-h neurological deficit scores (low dose, 1.75+/-0.5; high dose, 1.17+/-0.41; p<0.05 for both doses). A reduction in the percentage of infarct volume (low dose, 22.9+/-8.9%, p=0.002; high dose 7.6+/-3.4%, p<0.001) was seen when compared to the controls (infarct size, 54.2+/-9.0%; neurobehavior score, 2. 67+/-0.52). Treatment with TPM at the higher dose induced more neuroprotection than that at the lower dose (p<0.05). Thus, treatment with TPM resulted in a dose- and use-dependent neuroprotective effect, when used 2 h after MCA embolization in a rat model of focal ischemia.

RESUMO

Low molecular weight heparin (LMWH) has similar efficacy to unfractionated heparin with less hemorrhagic complications. We studied the neuroprotective effect of LMWH on a rat model of focal-ischemia. Our results revealed that treatment with LMWH at 1 and 3 h following thrombotic MCA occlusion reduced brain edema and infarct size and improved clinical outcome. Treatment with LMWH initiated at 6 h after thrombin injection only partially ameliorated brain damage.

RESUMO

A number of models of focal ischemia have been created to mimic acute middle cerebral artery (MCA) occlusion. In the present series of experiments, we report our observations on the thrombin model of MCA occlusion and the neuroprotective effects of intraarterial thrombolysis with two doses of urokinase (2500 and 5000 units/kg). In all experiments male Wistar rats were used and the animals were allowed to recover for 48 h before assessment of neurobehavioral performance on a four-point scale. The extent of cerebral hemispheric damage was calculated as the percentage of brain infarction using TTC staining. Occlusion of the MCA was effected by the introduction of an autologous blood clot into the internal carotid artery (ICA) approximately 2 mm from the origin of the MCA. This clot was formed by the drawing of 10 microl of blood into a bovine thrombin (20 microg per animal) containing intraarterial catheter, which was inserted into the right ECA. After standing for 15 min to allow clot formation, the catheter was advanced gently through the ICA to the site of injection. MCA occlusion produced a consistent large infarction in all animals. Urokinase infusion (i.a. ) was started 2 h after arterial occlusion in the initial series. In animals treated with low dose urokinase infusion there was mild protection. Animals treated with high dose urokinase infusion showed a highly significant improvement in the motor recovery and a decrease in the extent of infarction compared to control animals. In the final group, the infusion of urokinase was delayed for 3 h. While producing protection in some animals, it also produced intracerebral hemorrhage in two of eight animals. Thus delay of infusion to 180 min increased the risk of hemorrhage. This model may in the future be used to test the protective effects of combination therapy with thrombolysis and neuroprotective medications.
