Intravenous Immunoglobulin for the Treatment of Quetiapin-Induced Bullous Pemphigoid in an HIV-Infected Patient

The authors present the case of a 48-year-old woman with HIV-­associated dementia treated with antiretroviral therapy and psychoactive drugs, to whom bullous pemphigoid(BP) was diagnosed. Given incomplete response to corticotherapy, and azathioprine-­induced bicytopenia,intravenous immunoglobulin(IVIG) was initiated. Despite transient disease control, recurrent flares suggested a persistent triggering factor. Specifically, quetiapin was implicated and discontinued with an immediate clinical response. Inadvertent re-­challenge with olanzapine(a related drug)led to a new eruption, confirming drug-­induced BP (DIBP). A total of six IVIG cycles were completed, without severe side effects to report, namely HIV disease progression. HIV-­related autoimmune bullous diseases are rare. Treatment of severe drug eruptions is primarily based on immunossupressive drugs, raising concerns regarding additional immunossupression. This case suggests IVIG as a valuable option for the treatment of BP in HIV patients. In addition, quetiapin should be added to the list of neuroleptics previously linked to DIBP.

Conservative Treatment of Chondrodermatitis Nodularis Chronica Helicis with Topical Nitroglycerin

Background: Chondrodermatitis nodularis chronica helicis (CNCH) is a benign, painful, indurated inflammatory nodule arising on the pinna. Different treatment modalities have been used with varying efficacy rates. Despite lower efficacy, conservative methods are most desirable. Case reports: Three patients diagnosed with CNCH were treated with 0.4% topical nitroglycerin ointment, twice daily. These included two women and one man, aged 66, 86, and 60-years-old, respectively. Two painful nodules were located on the antihelix, and one on the helix. One patient had been previously treated with intralesional corticosteroids, and another with intralesional corticosteroids, CO2 laser and photodynamic therapy. All three patients experienced significant clinical and symptomatic improvement with topical nitroglycerin. No side effects were reported. Discussion: The etiology of CNCH is uncertain. Dermal and chondral ischemia arising from perichondrial arterial narrowing has been recently described as a possible cause for this benign condition, hence the potential of nitroglycerin as a smooth muscle relaxant and vasodilator. A previous report described significant improvement in twelve patients treated with 2% topical nitroglycerin. Conclusion: Topical nitroglycerin ointment appears to be a noninvasive alternative for the treatment of CNCH. A lower concentration (0.4%) may be as effective and with fewer side effects, but more studies are warranted.

Ponseti Method: Does Age at the Beginning of Treatment Make a Difference?

The Ponseti method is reportedly effective for treating clubfoot in children up to 9 years of age. However, whether age at the beginning of treatment influences the rate of successful correction and the rate of relapse is unknown. We therefore retrospectively reviewed 68 consecutive children with 102 idiopathic clubfeet treated by the Ponseti technique in four Portuguese hospitals. We followed patients a minimum of 30 months (mean, 41.4 months; range, 30–61 months). The patients were divided into two groups according to their age at the beginning of treatment; Group I was younger than 6 months and Group II was older than 6 months. All feet(100%) were initially corrected and no feet required extensive surgery regardless of age at the beginning of treatment. There were no differences between Groups I and II in the number of casts, tenotomies, success in terms of rate of initial correction, rate of recurrence, and rate of tibialis anterior transference. The rate of the Ponseti method in avoiding extensive surgery was 100% in Groups I and II; relapses occurred in 8% of the feet in younger and older children. Level of Evidence: Level II, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence.

The Role of Propranolol in the Treatment of Infantile Hemangioma

INTRODUCTION: Infantile hemangioma (IH) is one of the most common childhood tumors. There are various medical or surgical therapeutic options, all with suboptimal results. Recently, the successful use of propranolol for involution of IH was described. We report the results of a single-center experience with this therapeutic option. OBJECTIVE: To prospectively assess the efficacy and safety of propranolol in children with infantile hemangioma. METHODS: We performed a prospective analysis of clinical data of all patients with IH referred to a pediatric cardiology center for baseline cardiovascular assessment prior to propranolol therapy. Propranolol was given at a starting dose of 1 mg/kg/day and titrated to a target dose of 2-3 mg/kg/day according to clinical response. Efficacy was assessed through a photograph-based severity scoring scale. Safety was assessed by collecting data regarding significant side effects. RESULTS: Starting in 2010, 30 patients (15 female) were referred for propranolol treatment of IH, at a median age of six months (1-63 months). The mean target propranolol dose was 2.8 mg/kg/day, with a mean duration of therapy of 12 months. All patients experienced significant reduction of IH size and volume. There were no side effects. CONCLUSIONS: In our experience propranolol appears to be a useful and safe treatment option for severe or complicated IH, achieving a rapid and significant reduction in their size. No adverse effects were observed, although until larger clinical trials are completed, potential adverse events should be borne in mind and consultation with local specialists is recommended prior to initiating treatment.

The Oncological and Functional Risks of the Organ Preservation Experimental Treatment Approach

We increasingly face conservative surgery for rectal cancer and even the so called ‘wait and see’ approach, as far as 10–20% patients can reach a complete pathological response at the time of surgery. But what can we say to our patients about risks? Standard surgery with mesorectal excision gives a <2% local recurrence with a post operative death rate of 2–8% (may reach 30% at 6 months in those over 85), but low AR has some deterioration in bowel function and in low cancer a permanent stoma may be required. Also a long-term impact on urinary and sexual function is possible. Distant metastasis rate seem to be identical in the standard and conservative approach. It is difficult to evaluate conservative approach because a not clear standardization of surgery for low rectal cancer. Rullier et al tried to clarify, and they found identical results for recurrence (5–9%), disease free survival (70%) at 5y for coloanal anastomosis and intersphinteric resection. Other series have found local recurrence higher than with standard approach and functional results may be worse and, in some situations, salvage therapy is compromised or has more complications. In this context, functional outcomes are very important but most studies are incomplete in measuring bowel function in the context of conservative approach. In 2005 Temple et al made a survey of 122/184 patient after sphinter preserving surgery and found a 96.9% of incomplete evacuation, 94.4% clustering, 93.2% food affecting frequency, 91.8% gas incontinence and proposed a systematic evaluation with a specific questionnaire. In which concerns ‘Wait and see’ approach for complete clinical responders, it was first advocated by Habr Gama for tumors up to 7cm, with a low locoregional failure of 4.6%, 5y overall survival 96%, 72% for disease free survival; one fifth of patients failed in the first year; a Dutch trial had identical results but others had worse recurrence rates; in other series 25% of patients could not be salvaged even with APR; 30% have subsequent metastatic disease what seems equal for ‘wait and see’ and operated patients. In a recent review Glynne Jones considers that all the evaluated ‘wait and see’ studies are heterogeneous in staging, inclusion criteria, design and follow up after chemoradiation and that there is the suggestion that patients who progress while under observation fare worse than those resected. He proposes long-term observational studies with more uniform inclusion criteria. We are now facing a moment where we may be more aggressive in early cancer and neoadjuvant treatment to be more conservative in the subsequent treatment but we need a better stratification of patients, better evaluation of results and more clear prognostic markers.

Conscious Sedation with Inhaled 50% Nitrous Oxide/Oxygen Premix in Photodynamic Therapy Sessions for Vulvar Lichen Sclerosus Treatment

Photodynamic therapy has been described as an effective therapeutic option in selected cases of anogenital lichen sclerosus that are refractory to first-line treatments. However, procedure-related pain is a limiting factor in patient adherence to treatment. The authors report the case of a 75-year-old woman with highly symptomatic vulvar lichen sclerosus, successfully treated with photodynamic therapy. An inhaled 50% nitrous oxide/oxygen premix was administered during sessions, producing a pain-relieving, anxiolytic, and sedative effect without loss of consciousness. This ready-to-use gas mixture may be a well-tolerated and accepted alternative to classical anesthetics in Photodynamic therapy, facilitating patients' adherence to illumination of pain-prone areas.

Levonorgestrel Intrauterine Device Effectiveness in Heavy Menstrual Bleeding Treatment in Obese Women

Objective:We aimed to identify if there was any difference in Levonorgestrel-releasing intrauterine system (LNG-IUS) efficacy or weight gain when used in heavy menstrual bleeding (HMB) treatment, between obese and non-obese women. Population and methods: This was a case-controlled retrospective study undertaken between 2002-2007. 194 women with HMB were treated with LNG-IUS and stratified into two groups accordingly with body mass index (BMI): Obese Group – BMI ≥ 30 (n=53) and Non-obese Group – BMI < 30 (n=141). Age, weight, days of spotting and days of menses were analyzed at 1, 3 and 6 months after insertion and then annually until 2 years. Analytic parameters of anemia (hemoglobin, serum ferritin, mean corpuscular volume) were reviewed at pre-insertion, at 6 months and then annually until 2 years. Results: During the 2-year follow-up there was a similar improvement in two groups regarding duration of menses, spotting and in analytic parameters of anemia. A statistically significant improvement was observed in obese group after 2 years of treatment regarding analytic parameters of anemia and menstrual characteristics, without weight gain. Conclusion: In obese women, the LNG-IUS is an effective treatment for heavy menstrual bleeding, without being associated to weight gain.

Triple Regimen with Rituximab, Plasmapheresis and Intravenous Immunoglobulin in the Treatment of Dialysis Dependent Acute Humoral-Mediated Rejection in Kidney Grafts

Introduction: The clinical importance of humoral-mediated acute rejection has been progressively recognised. Early recognition and treatment with plasmapheresis and intravenous immunoglobulin have recently improved short term prognosis. Case report: In this report we describe the clinical features of three 2nd transplant patients developing severe acute humoral rejection during the first week post-transplant while on anti-thymocyte globulin therapy. Treatment with plasmapheresis/ intravenous immunoglobulin/rituximab resulted in rapid reversal of oliguria,and recovery of renal function within the 1st week of treatment in 2/3 patients. Diagnosis was confirmed by graft biopsies revealing peritubular neutrophiles and C4d deposits. Sequential graft biopsies in all three patients revealed complete histological recovery within two weeks. One patient never recovered renal function, and one patient lost his graft at three months following hemorrhagic shock. After 2 years follow up, the remaining patient maintains a serum creatinine of 1.1mg/dl. Conclusion: The regimen using plasmapheresis plus intravenous immunoglobulin and rituximab was effective in rapidly reversing severe acute humoral rejection.

Evaluation of CSF Neurotransmitters and Folate in 25 Patients with Rett Disorder and Effects of Treatment

Background: Rett disorder (RD) is a progressive neurodevelopmental entity caused by mutations in the MECP2 gene. It has been postulated that there are alterations in the levels of certain neurotransmitters and folate in the pathogenesis of this disease. Here we re-evaluated this hypothesis. Patients and Methods: We evaluated CSF folate, biogenic amines and pterines in 25 RD patients. Treatment with oral folinic acid was started in those cases with low folate. Patients were clinically evaluated and videotaped up to 6 months after therapy. Results: CSF folate was below the reference values in 32% of the patients. Six months after treatment no clinical improvement was observed. Three of the four patients with the R294X mutation had increased levels of a dopamine metabolite associated to a particular phenotype. Three patients had low levels of a serotonin metabolite. Two of them were treated with fluoxetine and one showed clinical improvement. No association was observed between CSF folate and these metabolites, after adjusting for the patients age and neopterin levels. Conclusion: Our results support that folinic acid supplementation has no significant effects on the course of the disease. We report discrete and novel neurotransmitter abnormalities that may contribute to the pathogenesis of RD highlighting the need for further studies on CSF neurotransmitters in clinically and genetically well characterized patients.

Anesthesia for Ex Utero Intrapartum Treatment: Renewed Insight on a Rare Procedure

The ex utero intrapartum treatment is a rare surgical procedure performed in cases of expected postpartum fetal airway obstruction. The technique lies on a safe establishment of a patent airway during labor in anticipation of a critical respiratory event, without interrupting maternal-fetal circulation. Anesthetic management is substantially different from that regarding standard cesarean delivery and its main goals include uterine relaxation, fetal anesthesia and preservation of placental blood flow. We present the case of an ex utero intrapartum treatment procedure performed on a fetus with a large cervical lymphangioma and prenatal evidence of airway compromise. Modifications to the classic ex utero intrapartum treatment management strategies were successfully adopted and will be discussed in the following report.

Percutaneous Treatment of Mitral Valve Regurgitation: Initial Experience with the MitraClip Device

INTRODUCTION: Mitral regurgitation (MR) is the most common valvular disease and has recently become the target of a number of percutaneous approaches. The MitraClip is virtually the only device for which there is considerable experience, with more than 20,000 procedures performed worldwide. OBJECTIVE: To describe our initial experience of the percutaneous treatment of MR with the MitraClip device. METHODS: We describe the first six MitraClip cases performed in this institution (mean age 58.5 ± 13.1 years), with functional MR grade 4+ and New York Heart Association (NYHA) heart failure class III or IV (n=3), with a mean follow-up of 290 ± 145 days. RESULTS: Procedural success (MR ≤ 2+) was 100%. Total procedure time was 115.8 ± 23.7 min, with no in-hospital adverse events and discharge between the fourth and eighth day, and consistent improvement in the six-minute walk test (329.8 ± 98.42 vs. 385.33 ± 106.95 m) and in NYHA class (three patients improved by two NYHA classes). During follow-up there were two deaths, in two of the four patients who had been initially considered for heart transplantation. CONCLUSION: In patients with functional MR the MitraClip procedure is safe, with both a high implantation and immediate in-hospital success rate. A longer follow-up suggests that the clinical benefit decreases or disappears completely in patients with more advanced heart disease, namely those denied transplantation or on the heart transplant waiting list.

Endoscopic Treatment of Early Gastric Obstruction After Sleeve Gastrectomy: Report of Two Cases

Morbid obesity is an epidemic and complex disease which imposes a multidisciplinary approach. Laparoscopic sleeve gastrectomy has become a frequent procedure given its effi- cacy and safety compared to other surgical options. However, it isn’t free from complications. Lax gastric fixation or incorrect positioning of the stomach during surgery can result in early gastric outlet obstruction caused by a volvulus-like mechanism by rotation of the stomach around its anatomic axes. This report refers to two cases of post sleeve gastric torsion resulting in persisting vomiting after initiating oral intake. The diagnosis was confirmed by upper gastrointestinal-contrast study and gastroscopy. In both cases, a fully covered self-expandable metallic stentwas insertedwhich prompted the gastric lumen to become permeable resulting in symptomatic resolution. The stents were removed endoscopically aftertwo and three months. Beyond more than three years offollow-up,the patients remain asymptomatic and no recurring ‘‘stenosis’’ was noticed.In these cases the use offully covered self-expandable metallic stents demonstrated to be effective and safe in the treatment of post sleeve gastric torsion.

Effectiveness of the Dexamethasone Intravitreal Implant for Treatment of Patients with Diabetic Macular Oedema

Diabetic macular oedema (DMO) is a leading cause of vision loss in the working-age population worldwide. Corticosteroid drugs have been demonstrated to inhibit the expression of both the vascular endothelial growth factor (VEGF) gene and other anti-inflammatory mediators, such as prostaglandins. Triamcinolone, fluocinolone and dexamethasone are the main steroids that have been studied for the treatment of macular oedema. Over the last few years, several studies have suggested an important role for dexamethasone in the management of DMO. The dexamethasone intravitreal implant (DEX implant) (Ozurdex®; Allergan, Inc., Irvine, CA) is a novel approach approved by the US Food and Drug Administration (FDA) and by the EU for the intravitreal treatment of macular oedema after branch or central retinal vein occlusion, and for the treatment of non-infectious uveitis affecting the posterior segment of the eye. We reviewed manuscripts that had investigated the pharmacokinetics, efficacy and safety of the DEX implant regarding DMO treatment.
