Anti-glomerular basement membrane disease: A case report of an uncommon presentation

Published on: 3rd April, 2019

OCLC Number/Unique Identifier: 8056273514

Anti-glomerular basement membrane (anti-GBM) disease is an uncommon autoimmune disease that classically presents as an aggressive necrotizing and crescentic glomerulonephritis (CG), with or without pulmonary hemorrhage, and typically does not relapse. The pathologic hallmark is linear staining of GBM for Immunoglobulin G (IgG) which binds to the alpha-3 chain of type IV collagen. Recent reports have noted the occurrence of anti-GBM disease with atypical clinical presentations. We describe a case of a 22-year-old female presenting an anti-GBM disease with typical histological features with a singular clinical presentation with lower limb edema, elevated serum creatinine and nephrotic range proteinuria. Renal biopsy showed signs of chronicity and direct immunofluorescence microscopy demonstrated diffuse, intense linear positivity for IgG. All serologic tests were negative, including anti-GBM antibodies. Hence, a diagnosis of atypical anti-GBM disease was made. The patient was treated initially with mycophenolate mofetil and corticosteroids. After 3 months she began to aggravate renal function so mycophenolate of mofetil was discontinued and a low dose cyclophosphamide was initiated.

“Bulls Eye For Bulls Teeth”- Endodontic Management of Taurodontism Using CBCT as A Diagnostic Tool- 2 Rare Case Reports

Published on: 20th January, 2017

OCLC Number/Unique Identifier: 7317595146

Taurodontism is a rare dental anomaly presented with an aberration of teeth that lacks the constriction at the level of the cemento-enamel junction (CEJ). It is characterized by elongated pulp chambers and apical displacement of bifurcation or trifurcation of the roots, forming a rectangular shape. Whilst, it appears most frequently as an isolated anomaly, its association with several syndromes and abnormalities has also been reported in the literature. Although permanent molars are most commonly affected, this anomaly could also be seen in deciduous dentition, unilaterally or bilaterally, and in any combination of teeth or quadrants. These morphological anomalies pose various challenges to the dentist during their endodontic treatment. Modern diagnostic tools such as Cone beam computed tomography (CBCT), loupes and Dental operating microscopes (DOM) help in achieving better treatment outcome in such cases. The presented article elaborates diagnosis and successful management of 2 rare cases of taurodontism in permanent molars.

The pattern of blood pressure and renal function among children with Sickle Cell Anaemia presenting in a tertiary health institution in Nigeria

Published on: 16th April, 2019

OCLC Number/Unique Identifier: 8163611724

Background: In sickle cell anemia (SCA), compromise of the renal vasculature due to sickled red cells has been recognized. Objectives: To assess the renal function and blood pressure pattern in children with sickle cell anaemia (SCA) presenting in a tertiary institution. Method: A cross-sectional study of patients with sickle cell anaemia (SCA) over six months involving the use of questionnaires, general physical examination, blood pressure, investigations for haemoglobin genotype, urinalysis, serum creatinine, screening for hepatitis B and HIV. Results: 51 children with SCA were seen. The prevalence of impaired renal function as defined by reduced eGFR <90mL/min/1.73m2 in this study was 27.5%, previous hospital admission and blood transfusion were associated with reduction in eGFR but blood pressure did not have significant correlation with the eGFR. The overall mean age at diagnosis of SCA was 4.09 ± 3.33 (years). Conclusion: Impaired renal function is a major comorbid condition in children with SCA. In countries/locations where there is no newborn screening for sickle cell disease, diagnosis is delayed, thus detecting impaired renal function may be delayed, therefore the need for early detection and management is imperative.Introduction

Diagnosis and Treatment of Anterior Cracked Tooth: A Case Report

Published on: 24th February, 2017

OCLC Number/Unique Identifier: 7317633425

Background: A cracked tooth may be challenging for dentists because it may present with varied intensities, may be asymptomatic, and may still not be clinically visible. The transilumination method can facilitate diagnosis and ensure appropriate treatment in such cases. The aim of the present article was to report a clinical case of an anterior cracked tooth with a nonesthetic class IV restoration. Clinical considerations: A 22-year-old male patient with chief complaint of esthetics of upper front tooth reported a history of dental trauma. Transilumination with a dental curing light unit was used to examine the region. The tooth 11 was diagnosed with several cracks and a nonesthetic class IV restoration. For repair, the universal adhesive system Scotchbond Universal was applied without previous acid etching, followed by the application of Filtek Z350 of color type B2 (for body) above the old restoration, taking care to slightly overlap the fracture line with the composite and to not extend the composite until the incisal margin. Subsequently, a thin layer of Filtek Z350 of color type B2 (for enamel) was applied over the bevel until the incisal margin, and the tooth shape was carved. Conclusion: This case report demonstrates simplified diagnosis of an anterior cracked tooth with transilumination; following repair, the esthetic quality of the restoration was considered satisfactory and approved by the patient.

Lateral Pancreato-Jejunostomy in Chronic Pancreatitis: An appraisal of 32 cases

Published on: 28th January, 2020

OCLC Number/Unique Identifier: 8530264916

Background: Lateral Pancreaticojejunostomy (LPJ) has recognized applications in the management of Chronic Pancreatitis (CP). It is done for patients with severe pain, obstructed and dilated pancreatic duct. Ductal obstruction by stone or stricture causes rise of intraductal pressure and parenchymal ischemia. Surgical decompression of the duct and ductal drainage can achieve best pain relieve and slow the progression of the disease. We want to share our experience of removal of stones and strictures from the pancreatic duct system and drainage of the main pancreatic duct by lateral pancreatojejunostomy (LPJ) for chronic pancreatitis in a teaching institute. Methodology: We studied 32 cases of chronic pancreatitis operated between January 2010 and January 2017 for a period of 7 years. Patients were selected with ultrasonography, CT scan and or Magnetic Resonance Cholangio Pancreatography (MRCP). Dilatation of the main pancreatic duct by at least 7 mm proximal to the obstruction were recruited for operation. We did Roux-Y lateral pancreato-jejunostomy for patients with obstruction of the pancreatic duct due to intraductal stones or strictures. Additional distal pancreatectomy were done in two cases for stones and/or abscess in the tail area. We did one Frey’s operation for stone and fibro-calcification of the head. In all cases ductal drainage was accomplished by LPJ. We studied their post-operative pain control, complications, recurrence and improvement of exocrine and endocrine function of pancreas and mortality during this period. We followed these patients for about 2 years after surgery. Results: We found 27 out of 32 patients got complete remission of the abdominal pain. Their progression of disease also slowed down. Ultrasonic evidence of chronic pancreatitis have improved or resolved. Ductal diameter have decreased. Two had recurrence of stones in the head and in the parenchyma within a year. 2 patients died during this follow-up period. One died three months after LPJ due to massive gangrene of the small intestine distal to LPJ and jejuno-jejunostomy and subsequent short bowel syndrome. Other one died of complications of diabetes and malabsorbtion. Pain free survival is about 84% and recurrence is 6%. Mortality during this follow up period is 6%. Conclusion: We found that surgery, if done early, can have good remission of abdominal pain and can slow the progression of chronic pancreatitis and prevent further stone formation in majority of patients. Patient’s exocrine and endocrine function improves or remain static. Patient with chronic calcific pancreatitis and diabetes are unlikely to have favorable outcome even after decompressive surgery.

Could metabolic risk factors contribute to the development of cervical cancer?

Published on: 18th December, 2019

OCLC Number/Unique Identifier: 8501565253

The role of human papillomavirus infection as etiological factor for cervical squamous intraepithelial lesions and cervical cancer is well established. However, the presence of this virus is not sufficient condition for developing of cervical cancer. Currently, the contribution of other viral, environmental and host cofactors in triggering of this neoplasm is being investigated. Some metabolic risk factors have been associated with the development of several gynecological cancers such as endometrium, ovary and cervix. However, the mechanisms through which these factors contribute to carcinogenesis are complex and not fully elucidated. Few interventions regarding host metabolic factors have been performed on women at risk of developing cervical cancer. Some specific treatments and or changes in lifestyles could be carried out to avoid or delay progression to this kind of cancer. This paper aims to enlarge and update this topic based on the article ¨Association between components of the metabolic syndrome and degree of cervical squamous intraepithelial lesions in Cuban women¨, with emphasis on possible mechanisms that explain the link between central adiposity, insulin resistance and dyslipidemia with risk of premalignant lesions and cervical cancer.

Congenital Quadricuspid Aortic Valve, a Rare Cause of Aortic Insufficiency in Adults: Case Report

Published on: 23rd January, 2017

OCLC Number/Unique Identifier: 7286350758

Quadricuspid aortic valve (QAV) is rare congenital malformation of the aortic valve with estimated prevalence of 0.013% to 0.043% [1-4]. QAV is most commonly associated with aortic insufficiency (AI), which is found in almost 75% of cases [5]. QAV can also be associated with other cardiac defects such as ventricular or atrial septal defects, patent ductus arteriosus, subaortic fibromuscular stenosis, malformation of the mitral valve, and coronary anomalies [3]. Up to 40% of all patients with QAV undergo aortic valve replacement surgery most commonly due to progressive AI in 88% of case [2,3,6]. Here we report a case from our institution of a woman with QAV with severe AI and anomalous origin of the right coronary artery.

Primary Cutaneous Lymphomas and Interferon Treatment

Published on: 9th January, 2017

OCLC Number/Unique Identifier: 7355942281

Primary cutaneous lymphomas (PCLs) are the second most common group of extranodal non-Hodgkin lymphomas (NHL) with an estimated annual incidence of 1/100.000. Interferons (IFNs) are used in mono or combination therapy for cutaneous lymphomas especially for cutaneous T-cell lymphomas (CTCL) for years. IFN-α is the most widely-used type for cutaneous lymphomas. IFN-α has been shown to be a highly active agent in CTCL with response rates ranging from 40% to 80%. In this review, the current information about PCLs and IFNs treatment is summarized.

A Perspective on Conservation Technologies for Endangered Marine Birds

Published on: 26th July, 2023

Seabirds are species in a collection of avian orders that live on and feed in saltwater and include penguins; albatrosses and petrels; gannets and cormorants; and gulls, terns, and auks. They are at risk from human activities with habitat loss, fisheries bycatch, food shortages, introduced predators and pollution impact. These effects are all exacerbated by human-induced climate change. Many researchers, non-governmental organizations, communities, and governments are working to conserve endangered seabird species by developing and implementing technologies and conservation management systems to assist seabird conservation. More recently moves are afoot to ensure organizations share data and outcomes.
