Background Primary nasopharyngeal lymphoma (NPL) is a very rare tumor of Waldeyer ring (WR) lymphoid tissue. It is challenging to differentiate lymphoma infiltration of pituitary from a pituitary adenoma, meningioma infiltration, and other sellar lesions to plan a suitable treatment strategy. We presented for the first time a unique case of NPL with an unusual presentation of oculomotor nerve palsy associated with pan-pituitary involvement in a diabetic patient. Case presentation A 64-year old diabetic woman with no previous history of malignancy presented with intermittent diplopia for about the last nine months. Severe headache, left eye ptosis and hypoglycemic episodes were added to her symptoms after a while. Further complaints include generalized weakness, loss of appetite, generalized musculoskeletal pain, and 6–7 kg weight loss within six months. Her family history was unremarkable. Physical examinations of eyes indicated left eye 3rd, 4th, and 6th nerve palsy. But, she was not anisocoric, and the pupillary reflexes were normal on both eyes. No lymphadenopathy, organomegaly and other abnormalities were found. Magnetic resonance imaging (MRI) showed a heterogeneous enhancement in the seller and suprasellar regions, enlargement of the stalk, parasellar dural enhancement and thickening of the sphenoid sinus without bone erosion. Also, both cavernous sinuses were infiltrated and both internal carotid arteries were encased by the neoplastic lesion. It suggested an infiltrative neoplastic lesion which compressed the cranial nerves. Pituitary hormone levels assessment indicated a pan-hypopituitarism. Following nasopharyngeal mucosal biopsy, the immunohistochemistry (IHC) findings revealed a low-grade non-Hodgkin’s B-cell lymphoma. Systemic workup, including cerebrospinal fluid (CSF) studies, bone marrow aspiration, chest and abdominopelvic high-resolution computed tomography (HRCT) indicated no other involvement by the lymphoma. After chemotherapy courses, central adrenal insufficiency, partial central diabetes incipidious (CDI) and central hypothyroidism have been resolved. To our best knowledge, we found 17 cases of NPL with cranial nerve palsy, 1 case of NPL with pan-hypopituitarism and no NPL case with both cranial nerve palsy and pituitary dysfunction. Conclusions The incidence of cranial neuropathy in patients with diabetes should not merely be attributed to diabetic neuropathy without further evaluation.
Background Type 2 Diabetes mellitus (T2DM) is one of the most common endocrine diseases that weakens the immune system. Candida albicans, is part of the natural oral flora and increases in cases of compromised immune systems. The exact cause of the increased prevalence of candidiasis in patients with T2DM is still unclear. The study aimed to correlate serum interleukin 10 (IL-10) and interferon-gamma cytokines (IFN-γ) with oral candidiasis in T2DM. Methods In this case–control study, 81 patients with T2DM and 41 non-diabetic individuals aged 30 to 70 years participated. Demographic information, a Blood sample (for blood glucose and cytokine tests), and an oral cotton swab sample from each individual were obtained. The samples were then incubated in a Sabroud dextrose agar medium. Colony growth was calculated and the type of yeast species in individuals with oral candidiasis was identified by culture in CHROMagar Candida medium. IL-10 and IFN-γ were measured by ELISA kit and the data were analyzed using SPSS-18. Results An overall of 122 participants comprised 73.77% females and 26.22% males. An increase in interleukin-10 by 40% and a decrease in IFN-γ by 6% can increase oral candidiasis prevalence among diabetic patients. Candida albicans was the most prevalent Candida species (spp.) in the diabetic and non-diabetic groups. The presence of oral candidiasis was not associated with HbA1c or FBS levels in both groups. Conclusion In the diabetic population, an increase in IL-10 or a decrease in IFN-γ may be associated with an increased risk of oral candidiasis.
Introduction: Hyperlipidemia is a common risk factor for diabetes and its cardiovascular complications. The aim of this study was to investigate the association between hemoglobin A1c (HbA1c) levels and serum lipids in patients with type 2 diabetes. Materials and Methods: This descriptive-analytical and cross-sectional study was conducted in 2016 on 484 patients with type 2 diabetes referred to the Diabetes Clinic in Gorgan, Iran. Blood samples were taken from all patients and sent to laboratory for measurement of HbA1c, FBS and serum lipids. Data were collected via registration forms. The data were analyzed with SPSS software (version 20) using independent t-test, Mann-Whitney U test and Pearson's and Spearman's coefficient tests. Results: Mean age of subjects was 56.61 ± 12.65 years with age range of 17 to 92 years. Mean duration of the disease was 13.52 ± 7.55 years (range: 1-44 years). Mean HbA1c level was 8.83 ± 1.8 mg/dl. There was a statistically significant correlation between HbA1c level and serum cholesterol (P=0.001), triglyceride (P=0.009), low-density lipoprotein (P=0.003) and FBS (P=0.0001). However, there was no statistically significant relationship between HbA1c and high-density lipoprotein levels (P= 0.8). Conclusions: High level of HbA1C is associated with dyslipidemia and can be used as predictors of cardiovascular disease in type 2 diabetes patients.
Diabetes mellitus (DM) is one of the most common chronic metabolic disorders worldwide, which increases the risk of common and opportunistic infections. Following the coronavirus disease 2019 (COVID-19) pandemic, a higher incidence rate, more severe forms of the disease, and exacerbation of hyperglycemia and its complications have been observed in patients with DM. Moreover, stress-induced hyperglycemia has been observed in many hospitalized nondiabetic patients after contracting COVID-19. Hyperglycemia worsens prognosis in both diabetic and nondiabetic patients. In this study, the mechanism of new-onset or exacerbation of hyperglycemia, the effect of the treatments used for COVID-19 on hyperglycemia, the importance and appropriate method of blood glucose (blood sugar (BS)) control during the disease, and the possible fate of new-onset hyperglycemia after recovery from COVID-19 to some extent is expressed.
