Disease-specific quality of life in patients with diabetic neuropathy.

OBJECTIVES: To compare health-related quality of life (HRQoL) among patients with diabetes mellitus (DM) and diabetic neuropathy (DN) (D+N) with patients with DM without DN (D-DN) and healthy participants. To evaluate factors associated with poor HRQoL in patients with DN. METHODS: This study included 306 participants residing in Bisha, Saudi Arabia. Patients with DM were screened for DN using the Michigan Neuropathy Screening Instrument. Neuropathy severity, disability and HRQoL were determined using the Neuropathy Severity Scale (NSS), the Neuropathy Disability Score (NDS), and the Norfolk Quality of Life-Diabetic Neuropathy (QOL-DN) tool, respectively. Nerve conduction studies (NCSs) were also performed. RESULTS: The D+DN group had poorer overall and domain HRQoL scores compared to the D-DN group (p<0.001). There was a strong correlation between overall HRQoL score and both NDS and NSS scores in the D+DN group (ρ= -0.71 and p<0.0001; ρ= -0.81 and p<0.0001, respectively). There was also a significant difference in all mean HRQoL domain scores between D+DN participants with normal and abnormal NCS. Physical inactivity (p=0.043), duration of DM (p<0.0001), abnormal NCS, NSS (p<0.0001), and NDS (p<0.0001) predicted HRQoL in the D+DN group. CONCLUSION: D+DN participants had a worse HRQoL compared with D-DN and healthy counterparts. NDS, NNS, physical inactivity, abnormal NCS, and duration of DM independently predicted poor HRQoL in D+DN participants.

Emphysematous Cystitis: A Radiological Diagnosis of Potentially Life-Threatening Infection.

Urinary tract infections are very prevalent among women. The majority of urinary tract infections are uncomplicated and can be managed empirically with no further investigations. However, imaging studies may be indicated in patients with severe or persistent symptoms. Complicated urinary tract infections typically develop in the setting of diabetes mellitus. We report a case of a 52-year-old woman who presented to the emergency department with severe lower abdominal pain for two days that was associated with nausea, vomiting, and fever. There was no history of change in urine or bowel habits. Besides the history of well-controlled asthma, the patient was not known to have any comorbid medical condition. Upon examination, the patient had tachycardia, low-grade fever, and a localized suprapubic tenderness with guarding. Laboratory investigation revealed leukocytosis, elevated erythrocyte sedimentation rate and C-reactive protein, and deranged renal functions. Further, urinalysis revealed numerous white blood cells, red blood cells, positive nitrite, and leukocyte esterase. A computed tomography scan demonstrated the presence of small locules of gas within the lumen and the wall of the bladder representing emphysematous cystitis. The patient was admitted to the intensive care unit. She received aggressive hydration therapy and a short course of opioid therapy for pain control. Broad-spectrum antibiotic therapy in the form of piperacillin-tazobactam was initiated. Over the following few days, the patient exhibited significant improvement in his symptoms and resolution of the laboratory parameters. Emphysematous cystitis is a rare infection of the lower urinary tract with gas formation. The case highlighted that such a condition may develop in the absence of diabetes mellitus or other risk factors. Prompt treatment is crucial as emphysematous cystitis can be life-threatening if the diagnosis is missed or delayed.

Effect of sorafenib starting dose and dose intensity on survival in patients with hepatocellular carcinoma: Results from a Canadian Multicenter Database.

BACKGROUND: Sorafenib has been shown to improve survival in patients with advanced hepatocellular carcinoma (HCC), however, full dose can be difficult to tolerate. The aim of this study was to determine whether sorafenib starting dose and mean dose intensity affect survival. METHODS: Patients treated with sorafenib for HCC from January 2008 to July 2016 in several Canadian provinces were included and retrospectively analyzed. The primary end point was overall survival (OS) of patients starting on sorafenib full dose compared to reduced dose. Secondary analysis compared OS with different mean dose-intensity groups. Survival outcomes were assessed with Kaplan-Meier curves and Cox proportional hazards models. A propensity score analysis was performed to account for treatment bias and confounding. RESULTS: Of 681 patients included, sorafenib was started at full dose in 289 patients (42%). Median survival for starting full and reduced dose was 9.4 months and 8.9 months (P = .15) respectively. After propensity score matching and adjusting for potential confounders there was still no difference in survival (HR 0.8, 95% CI, 0.61-1.06, P = .12). Almost half of the patients (45%) received a dose intensity < 50%. Median survival for mean dose intensity > 75%, 50%-75%, and < 50% were 9.5 months, 12.9 months, and 7.1 months (P = .005) respectively. In multivariable models, starting dose(HR 1.16, 95% CI 0.93-1.44, P = .180) and mean dose intensity were not associated with survival. CONCLUSIONS: Starting HCC patients on a reduced dose of sorafenib compared to full dose may not compromise survival. Mean dose-intensity of sorafenib may also not affect survival.

Incidental Extraspinal Findings in the Thoracic Spine during Magnetic Resonance Imaging of Intervertebral Discs.

OBJECTIVE: The purpose of this research was to determine the frequency of incidental extraspinal findings in the thoracic spine on magnetic resonance imaging (MRI). MATERIALS AND METHODS: A total of 120 thoracic spine MRI patients were prospectively examined in the period extending from August 2018 to April 2019. Both 1.5 and 0.35 Tesla MRI systems (Toshiba and Siemens Medical system) were applied to investigate patients with suspected intervertebral disc abnormalities at three MRI diagnostic centers in Khartoum, Sudan. RESULTS: Out of the 120 patients, incidental extraspinal findings were found in 16 patients (13.3%). Various incidental findings (IFs) were seen, including renal cysts, liver mass, thyroid goiter, and pleural effusion. Out of these IFs, 37.5% were considered clinically significant. CONCLUSIONS: Various IFs were identified during a routine thoracic spine MRI, and approximately one-third of them were clinically significant. Therefore, it is essential for the reporting radiologists to pay attention to extraspinal findings while reporting thoracic spine MRI to avoid missing clinically significant findings.
