Selected AbstractsSphincter of Oddi dysfunction: role of sphincterotomyDIGESTIVE ENDOSCOPY, Issue 4 2001Choichi Sugawa Sphincter of Oddi dysfunction (SOD) is one of the causes of post-cholecystectomy syndrome and biliary pain and is a challenge from both the diagnostic and therapeutic points of view. Sphincter of Oddi dysfunction is typically diagnosed months to years after cholecystectomy. Continued biliary type pain after cholecystectomy may occur in as many as 10,20% of patients. Ten percent or more of these patients may eventually be shown to have SOD. The syndrome is often associated with a variety of other gastrointestinal disorders thought to be caused by dysmotility. According to the Milwaukee classification, patients with biliary pain can be divided into three types. Type I patients show all the objective signs suggestive of a disturbed bile outflow (i.e. elevated liver function tests, dilated common bile duct and delayed contrast drainage during endoscopic retrograde cholangiopancreatography). Type II patients have biliary type pain along with one or two of the criteria from type I. Type III patients have biliary pain only, with no other abnormalities. The present paper will focus primarily on SOD syn-drome, papillary stenosis and the diagnostic and therapeutic approaches, in particular endoscopic sphincterotomy.

Priest MD Abstract Background Pleuropulmonary blastoma (PPB) is a rare tumor of pleura and lung in young children. Central nervous system (CNS) complications, particularly cerebral parenchymal metastases, occur in aggressive forms of PPB: Types II and III PPB. This article evaluates cerebral and meningeal metastases, cerebrovascular events (CVA) caused by tumor emboli, spinal cord complications, and intracranial second malignancies in PPB. Procedure International PPB Registry and literature cases were evaluated for CNS events. Cerebral metastasis patients were evaluated for gender, side of origin of PPB, PPB Type, interval from diagnosis to metastasis, status of chest disease, treatment, and outcome. Standard statistical methods were used to calculate the cumulative probability of cerebral metastasis and survival following metastasis. Results Thirty-nine cases of cerebral metastasis were identified in 5/53 Registry Type II cases, 15/44 Registry Type III cases, and 19/143 literature Type II/III cases. Metastases occurred 1,60, median 11.5 months after diagnosis. Chest disease was controlled in 50% of children at time of metastasis. The cumulative probability of cerebral metastasis by 5 years from diagnosis was 11% for Type II patients (95%CI (confidence interval): 2,20%) and 54% for Type III patients (95%CI: 31,76%). Seven children survive cerebral metastasis. Other CNS complications were post-operative CVA (five cases), spinal cord invasion or compression (six), leptomeningeal disease (three), and second intracranial malignancies (two). Conclusions Cerebral metastasis is more frequent in PPB than in other childhood sarcomas. Clinicians should screen for this complication. Diverse other CNS complications are less common and require careful diagnosis. Pediatr Blood Cancer 2007;49:266,273. © 2006 Wiley-Liss, Inc. [source] Laser Hair Removal: Long-Term Results with a 755 nm Alexandrite LaserDERMATOLOGIC SURGERY, Issue 11 2001Sorin Eremia MD Background. Hypertrichosis is a common problem for which laser hair removal is becoming the treatment of choice. Optimal wavelength, pulse duration, spot size, fluence, and skin cooling parameters for various skin types have not yet been firmly established. Objective. To evaluate the long-term efficacy and safety of a 3-msec 755 nm alexandrite laser equipped with a cryogen cooling device for patients with Fitzpatrick skin types I,V. Methods. Eighty-nine untanned patients with skin types I,V underwent a total of 492 treatments of laser hair removal over a 15-month period. Each patient in the study underwent a minimum of three treatment sessions spaced 4,6 weeks apart (mean treatments 5.6). Retrospective chart review and patient interviews were used to establish hair reduction results. Treatment sites included the axillae, bikini, extremities, face, and trunk. A 3-msec pulse width, 755 nm alexandrite laser equipped with a cryogen spray cooling device was used in this study. Spot sizes of 10,15 mm were used. A spot size of 10 mm was used for fluences greater than 40 J/cm2, a spot size of 12 mm was used for fluences of 35,40 J/cm2, and spot sizes of 12 and 15 mm were used for fluences less than 30 J/cm2. Fluences ranging from 20 to 50 J/cm2 (mean fluence 36 J/cm2) were used. Results. The patients had a mean 74% hair reduction. Skin type I patients had an average of 78.5% hair reduction using a mean fluence of 40 J/cm2 (35,50 J/cm2) and a 10,12 mm spot size (12 mm in more than 95% of treatments). Skin type II patients had a mean 74.3% hair reduction using a mean fluence of 38 J/cm2 (30,40 J/cm2) and a 12,15 mm spot size. Skin type III patients had a mean 73.4% hair reduction using a mean fluence of 37 J/cm2 (25,40 J/cm2) and a 12,15 mm spot size. Skin type IV patients had a mean 71.0% hair reduction using a mean fluence of 31 J/cm2 (25,35 J/cm2) and a 12,15 mm spot size. A patient with skin type V had a 60% hair reduction using a mean fluence of 23 J/cm2 (20,25 J/cm2) and a 12,15 mm spot size. The efficiency of hair removal directly correlates significantly with the fluence used. Rare side effects included transient postinflammatory hyperpigmentation (n = 9; 10%), burn with blisters (n = 1; 1%), and postinflammatory hypopigmentation (n = 2; 2%). All complications resolved without permanent scarring. Conclusion. The 3-msec cryogen cooling-equipped alexandrite laser can safely and effectively achieve long-term hair removal in patients with skin types I,V. The best results are achieved in untanned patients with skin types I,IV. [source] A Novel Single Nucleotide Polymorphism of the Neuropeptide Y (NPY) Gene Associated With Alcohol DependenceALCOHOLISM, Issue 5 2005Salim Mottagui-Tabar Background: Neuropeptide Y (NPY) is a major endogenous regulator of anxiety-related behaviors and emotionality. Transgenic work with NPY and null-mutant mice have implicated NPY in the control of alcohol consumption, suggesting that genetic variation of the prepro-NPY gene may also contribute to the heritability of alcoholism. The aim of this study was to examine whether polymorphic variants of the NPY gene are associated with the diagnosis of alcohol dependence. Methods: We compared allele frequencies of 5 NPY polymorphisms (,883-ins/del, ,602, ,399, ,84, and +1128) in a Nordic population of alcohol-dependent individuals (n= 428 males; n= 149 females) and ethnically matched controls (n= 84 males; n= 93 females) for whom alcohol dependence or any diagnosis of substance disorder was excluded. Patients were further subtyped into type I (late-onset) and type II (early-onset) alcoholics. Results: The ,602 marker showed a significant association with alcohol dependence (p= 0.0035; OR, 2.3; 95% CI, 1.3-4.0); a trend level association was further observed for the ,399 marker (p= 0.058; OR, 1.3; 95% CI, 0.99-1.7) and the +1128 marker (p= 0.053; OR, 1.8; 95% CI, 0.99-3.1). The association for the ,602 marker remained and was strengthened when analyzed in type I subjects only, although this association was not seen in type II patients, and there also was a significant association in the female subjects but not in males. The ,602 single nucleotide polymorphism was in strong linkage dysequilibrium (r2= 0.7; p < 0.0001) with the +1128 single nucleotide polymorphism, which has previously been reported to be associated with a diagnosis of alcoholism. Haplotype-based association confirmed these results. Conclusions: We report a novel polymorphism at position ,602 in the 5, region of the NPY gene that is significantly associated with alcohol dependence. We also describe the haplotype frequencies and linkage dysequilibrium pattern of four variations in that region. [source] Electrophysiological findings of peripheral neuropathy in newly diagnosed type II diabetes mellitusJOURNAL OF THE PERIPHERAL NERVOUS SYSTEM, Issue 4 2005Eugenia Rota Abstract This study was aimed at assessing the electrophysiological signs of peripheral neuropathy in diabetes mellitus (DM) type II patients at diagnosis. Nerve conduction studies (NCS) of median, ulnar, peroneal, tibial and sural nerves were performed in 39 newly diagnosed DM subjects and compared to those of 40 healthy controls. Metabolic indices were also investigated. Electrophysiological alterations were found in 32 (82%) of the DM patients, and more than half of them (62.2%) showed multiple (two to five) abnormal parameters. Because most of the subjects (84.4%) had from two to five nerves involved, these alterations were widespread in the seven nerves evaluated. Forty-two percent of the patients had NCS alterations suggestive of distal median mononeuropathy, implying that metabolic factors in DM make the median nerve more susceptible to focal entrapment. A reduced sensory nerve action potential (SNAP) amplitude was observed in the median nerve in 70% of the patients, in the ulnar in 69% and in the sural nerve only in 22%. In the presence of a decrease in the SNAP amplitude of the ulnar or median nerve, the SNAP amplitude of the sural nerve was normal in 82 or 80% of the subjects, respectively. This finding may be in keeping with a distal involvement of the sensory fibres, as explored by routine median or ulnar NCS. No correlation was found between metabolic indices and NCS parameters. In conclusion, a high percentage of newly diagnosed DM patients show signs of neuropathy, and upper limb nerve sensory NCS seem to be more sensitive in detecting it than lower limb NCS. [source] |
