Bladder Mucosal Graft Vaginoplasty: A Case Report

Background

Female vaginoplasty reconstruction, by choice, is usually performed with adjacent tissue. However in some clinical conditions such as high urogenital confluence sinus, cloacal malformation with extreme vaginal hypoplasia, local tissue may not be available. When vaginal replacement is performed in pediatric patients intestinal segments is preferred to non-operative procedures that require continuative dilations. However mucus production, malignant transformation risk and diversion colitis are important side effects.

Reactive vaccination as control strategy for an outbreak of invasive meningococcal disease caused by Neisseria meningitidis C:P1.5-1,10-8:F3-6:ST-11(cc11), Bergamo province,Italy, December 2019 to January 2020

In Italy, serogroup C meningococci of the clonal complex cc11 (MenC/cc11) have caused several outbreaks of invasive meningococcal disease (IMD) during the past 20 years. Between December 2019 and January 2020, an outbreak of six cases of IMD infected with MenC/cc11 was identified in a limited area in the northern part of Italy. All cases presented a severe clinical picture, and two of them were fatal. This report is focused on the microbiological and molecular analysis of meningococcal isolates with the aim to reconstruct the chain of transmission. It further presents the vaccination strategy adopted to control the outbreak. The phylogenetic evaluation demonstrated the close genetic proximity between the strain involved in this outbreak and a strain responsible for a larger epidemic that had occurred in 2015 and 2016 in the Tuscany Region. The rapid identification and characterisation of IMD cases and an extensive vaccination campaign contributed to the successful control of this outbreak caused by a hyperinvasive meningococcal strain.     

Obesity and Excess Protein and Carbohydrate Consumption Are Risk Factors for Thyroid Cancer

Conflicting data concerning the association between obesity and differentiated thyroid cancer (DTC) may be attributed to the lack of records showing dietary intake and inadequate evaluation of nutrient composition. We evaluated 115 DTC patients carefully paired with 103 healthy control individuals by using a structured questionnaire, including a 24-h recordatory during 3 days, to investigate calorie intake and macronutrient (proteins, carbohydrates, and lipids) composition of the diet. We observed that excess weight (body mass index > 25 kg/m²) increased individual susceptibility to DTC [odds ratio (OR) = 3.787; 95% confidence interval (CI) = 1.115–6.814; P < 0.0001). This augmented risk was evident in women (OR = 1.925; 95% CI = 1.110–3.338; P = 0.0259) but not in men (P = 0.3498). Excess calorie intake was more frequent in patients with DTC than in controls (OR = 5.890; 95% CI = 3.124–11.103; P < 0.0001), and both excess protein (OR = 4.601; 95% CI = 1.634–12.954; P = 0.0039) and carbohydrate (OR = 4.905; 95% CI = 2.593–9.278; P < 0.0001) consumption were associated with an increased risk of DTC, contrarily to lipid/fiber intake and physical activity (P = 0.894 and 0.5932, respectively). In conclusion, our data indicate that overweight and risk of DTC are associated with higher protein and carbohydrate consumption than the rates recommended by the World Health Organization. The nutritional orientation should be part of preventive strategy targets designed to combat the increasing incidence of both obesity and DTC.     

Multiple facets in the control of acromegaly

Aims

The current article provides a brief overview of the criteria for defining disease control in acromegaly.

Methods

This was a retrospective, narrative review of previously published evidence chosen at the author’s discretion along with an illustrative case study from Latin America.

Findings and Conclusions

In the strictest sense, “cure” in acromegaly is defined as complete restoration of normal pulsatile growth hormone secretion, although this is rarely achieved. Rather than “cure”, as such, it is more appropriate to refer to disease control and remission, which is defined mainly in terms of specific biochemical targets (for growth hormone and insulin-like growth factor-1) that predict or correlate with symptoms, comorbidities and mortality. However, optimal management of acromegaly goes beyond biochemical control to include control of tumour growth (which may be independent of biochemical control) and comprehensive management of the symptoms and comorbidities typically associated with the disease, as these may not be adequately managed with acromegaly-specific therapy alone.

     

Eosinophilic angiocentric fibrosis of the sinonasal tract: report on the clinicopathologic features of a case and review of the literature

BACKGROUND: Eosinophilic angiocentric fibrosis (EAF) is a rare fibroinflammatory lesion of the sinonasal tract that occurs mainly in young to middle-aged female patients. Only two previous cases affecting male patients have been reported, and its etiopathogenesis remains unknown. The authors report on the third case of the entity in a male patient and review the 12 previously reported cases. CASE REPORT: A 52-year-old male patient was initially seen with a 15 years history of allergic rhinitis, progressive nasal obstruction, and left-sided hearing loss. All laboratory tests were unremarkable, except the nasal discharge eosinophil count that showed a conspicuous eosinophilia. The video-assisted-nasofibroscopic examination and CT scans disclosed a thickened deviated nasal septum with a subjacent infiltrative lesion. The histologic analysis of the nasal septum showed a variable mixed inflammatory cellular infiltration mainly composed of eosinophils, plasma cells, and histiocytes with a perivascular distribution; in other areas, an angiocentric fibrosing lesion with a peculiar perivascular onion-skin pattern was observed. The patient had a partial resection of the lesion with symptomatic control. CONCLUSIONS: The presence of rhinitis and nasal eosinophilia in our case associated with the clinical aspects of the previously reported cases further support an allergic cause for EAF.     

Patients with Fabry disease on dialysis in the United States.

BACKGROUND.: Fabry disease results from an X-linked deficiency of lysosomal alpha-galactosidase A and is a rare cause of end-stage renal disease. Little is known about the characteristics of patients with Fabry disease that initiate dialysis in the United States, although data from Europe suggests these individuals have a poor survival. METHODS.: Using the United States Renal Disease System database, we first studied in detail 42 Fabry patients who initiated dialysis between April 1995 (following the introduction of the new detailed HCFA 2728 form) and July 1998. To examine crude survival in a larger cohort, 95 Fabry patients were studied who initiated dialysis between 1985 and 1993, similar to the European Registry. Diabetic and non-diabetic controls matched by age, gender, race, year of dialysis initiation, and initial dialysis modality were examined for comparison. RESULTS.: During the years 1995 to 1998, the mean age of Fabry patients that initiated dialysis was 42 years, 83% were Caucasian, and 10% were African American. Despite the X-linked inheritance of Fabry disease, 12% of Fabry patients on dialysis were female. At initiation of dialysis mean serum albumin and creatinine were significantly higher and mean body mass index was significantly lower among Fabry patients, but mean glomerular filtration rate was similar to controls. Fabry patients tended to have a lower three-year survival compared to non-diabetic controls, but the results were not significantly different. In a larger cohort of Fabry patients who initiated dialysis between 1985 and 1993, the three-year survival of Fabry patients was significantly lower than non-diabetic controls: 63% (95% CI, 50 to 75%) versus 74% (95% CI, 67 to 80%; P=0.03). CONCLUSION.: End-stage renal disease is associated with significant morbidity and mortality among patients with Fabry disease. Recent evidence that progression of Fabry disease may be attenuated by enzyme replacement therapy necessitates increased awareness of Fabry disease and its comorbidities.
