Metronidazole associated optic neuritis-induced irreversible vision loss: A case report and literature review.

Optic neuritis is an inflammatory condition involving the optic nerve causing vision abnormalities ranging from decreased to complete vision loss. We present a 30 years old lady who suffered acute gradual reduced vision, which progressed to complete vision loss in her right eye the next day after receiving one dose of intravenous Metronidazole.

Mucosal Schwann Cell Hamartoma on Screening Colonoscopy: An Unusual Finding.

Schwann cells are found in the peripheral nervous system and can sometimes appear as benign hamartoma lesions in various parts of the body. Although rare in the gastrointestinal (GI) tract, they have been observed in the colon. Recently, mucosal Schwann cell hamartomas of the GI tract have been studied, and it was discovered that they had yet to be investigated up to 2009. In this context, we present the case of a 60-year-old man who was found to have lesions in the transverse colon during a routine colonoscopy. No further investigations were conducted since these lesions have not been associated with any risk of malignancy transformation and have not been linked to any inherited syndromes. LEARNING POINTS: Mucosal Schwann cell hamartomas are rare types of polyps that can be found anywhere in the gastrointestinal tract.They are benign lesions not usually associated with any inherited syndrome and they are usually found incidentally by endoscopy.These polyps are benign and might not require further follow-up once diagnosed.

Differential evolution of diabetic ketoacidosis in adults with pre-existent versus newly diagnosed type 1 and type 2 diabetes mellitus.

BACKGROUND: Diabetic ketoacidosis (DKA) was once known to be specific to type-1 diabetes-mellitus (T1D); however, many cases are now seen in patients with type-2 diabetes-mellitus (T2D). Little is known about how this etiology shift affects DKA's outcomes. METHODS: We studied consecutive index DKA admissions from January 2015 to March 2021. Descriptive analyses were performed based on pre-existing T1D and T2D (PT1D and PT2D, respectively) and newly diagnosed T1D and T2D (NT1D and NT2D, respectively). RESULTS: Of the 922 patients, 480 (52%) had T1D, of which 69% had PT1D and 31% NT1D, whereas 442 (48%) had T2D, of which 60% had PT2D and 40% NT2D. The mean age was highest in PT2D (47.6 ± 13.1 years) and lowest in PT1D (27.3 ± 0.5 years) (P < 0.001). Patients in all groups were predominantly male except in the PT1D group (55% females) (P < 0.001). Most patients were Arabic (76% in PT1D, 51.4% in NT1D, 46.6% in PT2D) except for NT2D, which mainly comprised Asians (53%) (P < 0.001). Patients with NT2D had the longest hospital length of stay (LOS) (6.8 ± 11.3 days) (P < 0.001), longest DKA duration (26.6 ± 21.1 h) (P < 0.001), and more intensive-care unit (ICU) admissions (31.2%) (P < 0.001). Patients with PT1D had the shortest LOS (2.5 ± 3.5 days) (P < 0.001), DKA duration (18.9 ± 4.2 h) (P < 0.001), and lowest ICU admissions (16.6%) (P < 0.001). CONCLUSIONS/INTERPRETATION: We presented the largest regional data on differences in DKA based on the type and duration of diabetes- mellitus (DM), showing that T2D is becoming an increasing cause of DKA, with worse clinical outcomes (especially newly diagnosed T2D) compared to T1D.

Clinical and biochemical determinants of length of stay, readmission and recurrence in patients admitted with diabetic ketoacidosis.

BACKGROUND: The increasing prevalence of diabetic ketoacidosis (DKA) related admissions poses a significant burden on the healthcare systems globally. However, data regarding the predictors of healthcare resource utilization in DKA is limited and inconsistent. This study aimed to identify key predictors of hospital length of stay (LOS), readmission and recurrent DKA episodes. METHODS: We undertook a retrospective cross-sectional analysis of all DKA admissions from 2015 to 2021 across four hospitals in Qatar. The primary outcomes were the length of stay (LOS), 90-day readmission and 6-month and 1-year DKA recurrence. RESULTS: We included 922 patients with a median age of 35 years (25-45). 62% were males with type-1 diabetes-mellitus (T1DM) and type-2 DM (T2DM), present in 52% and 48% of patients. The median LOS was 2.6 days (IQR 1.1-4.8), and the median DKA resolution time was 18 h (10.5-29). Male-gender, new-onset DM, higher Charlson Comorbidity Index (CCI), lower haemoglobin, sodium and potassium, higher urea, longer DKA duration and MICU admission predicted a longer LOS in a multivariate regression analysis. None of the factors were significantly associated with 90-day readmission. Patients with pre-existing T1DM were more likely to have a six-month DKA recurrence than pre-existing T2DM. Patients with a 6-month DKA recurrence, female gender and T1DM had higher odds of 12-month recurrence, whereas a consult with a diabetes educator at the index admission was associated with decreased odds of recurrence. CONCLUSIONS/INTERPRETATION: This is the most extensive study from the Middle-East region reporting on LOS, readmissions and the recurrence of DKA. Results from this study with a diverse population may be valuable for physicians and healthcare systems to decrease the diabetes-related healthcare burden in DKA patients.

Sensory neural hearing loss in Behcet's disease successfully controlled with infliximab, case report and review of literature.

Behcet's disease is a systemic autoimmune disorder occasionally associated with otological manifestations, including sensorineural hearing loss. We are reporting a case of Behcet's disease, which was complicated by sensorineural hearing loss and managed successfully with anti-TNF agent Infliximab.

Co-infection by Cryptococcus neoformans fungaemia and non-tuberculous mycobacteria with Pneumocystis jiroveci pneumonia in a newly diagnosed HIV-infected patient.

Opportunistic infections are common in human immunodeficiency virus (HIV)-infected patients. Co-infections with Cryptococcus neoformans and Mycobacterium species together with Pneumocystis jiroveci pneumonia (PCP) are rare and typically occur in immunocompromised individuals, particularly acquired immunodeficiency syndrome patients.
