Delayed diagnosis of a retained guidewire after bedside femoral venous catheter insertion: A preventable complication.

Central venous catheter (CVC) insertion is a commonly performed procedure that is used for continuous invasive hemodynamic monitoring, fluid resuscitation, drug therapy, and hemodialysis. CVC placement can be associated with serious complications that are mostly preventable. One of these complications is the loss of the guidewire within the intravascular space, which carries a high morbidity and mortality. Here, we describe a 44-year old patient who presented with acute kidney injury and metabolic derangements that necessitated bedside right femoral dialysis catheter to initiate emergent renal replacement therapy. A day after the catheter insertion, the guidewire was noted on a routine chest X-ray extending into the base of the skull. The clinical course was complicated with cerebral infarction. Subsequently, the retained guidewire was removed a few days after the CVC insertion. In summary, the retained guidewire within the circulation is associated with potentially life-threatening and hazardous outcomes. Continuing education, vigilant supervision, and implementing certain protocols are likely to prevent such undesirable events.

Recurrent COVID-19 in Hemodialysis: A Case Report of 2 Possible Reinfections.

Patients receiving in-center hemodialysis are at high risk for infections due to relative immunosuppression, limited ability to physically distance, and frequent encounters with the health care setting. This has been particularly evident during the coronavirus disease 2019 (COVID-19) pandemic. We describe 2 patients with suspected recurrent COVID-19 infection, each with documented clearance of virus between episodes. The duration between a negative reverse-transcription polymerase chain reaction test result for severe acute respiratory syndrome coronavirus 2 and symptomatic reinfection was 31 and 55 days, respectively, in the 2 patients. A higher risk for infection with COVID-19 and poor outcomes if infected, including ≥20% short-term mortality risk, is worrisome in this patient population. Continued measures such as infection prevention, community outreach, and early testing may play a role in establishing protocols to protect the vulnerable dialysis population.

Central Venous Occlusion in the Hemodialysis Patient.

Central venous stenosis (CVS) is encountered frequently among hemodialysis patients. Prior ipsilateral central venous catheterization and cardiac rhythm device insertions are common risk factors, but CVS can also occur in the absence of this history. Chronic CVS can cause thrombosis with partial or complete occlusion of the central vein at the site of stenosis. CVS is frequently asymptomatic and identified as an incidental finding during imaging studies. Symptomatic CVS presents most commonly as an upper- or lower-extremity edema ipsilateral to the CVS. Previously unsuspected CVS may become symptomatic after placement of an ipsilateral vascular access. The likelihood of symptomatic CVS may be affected by the central venous catheter (CVC) location; CVC side; duration of CVC dependence; type, location, and blood flow of the ipsilateral access; and extent of collateral veins. Venous angiography is the gold standard for diagnosis. Percutaneous transluminal angioplasty and stent placement can improve the stenosis and alleviate symptoms, but CVS typically recurs frequently, requiring repeated interventions. Refractory symptomatic CVS may require ligation of the ipsilateral vascular access. Because no available treatment option is curative, the goal should be to prevent CVS by minimizing catheters and central vein instrumentation in patients with chronic kidney disease and dialysis patients.

Association between bipolar affective disorder and thyroid dysfunction.

BACKGROUND: Bipolar affective disorder may be associated with alterations in thyroid function. A comprehensive thyroid assessment is important for assessing clinical and sub-clinical imbalances linked to a variety of mood disorders like bipolar affective disorder. AIM: To find out the association between bipolar affective disorder and thyroid dysfunction. MATERIALS AND METHOD: The present cross-sectional study was conducted at Government District Wenlock Hospital, Mangalore (GDWH), India. A total of 50 newly diagnosed bipolar affective disorder patients and 50 age and sex matched controls without bipolar affective disorder as confirmed by the application of Bipolar Spectrum Diagnostic Scale were included in the study. Thyroid function was assessed among the patients and control group to study the association between bipolar affective disorder and thyroid dysfunction. Odds ratio was calculated to find out the strength of association between thyroid gland dysfunction and bipolar affective disorder. RESULTS: The mean Bipolar Spectrum Diagnostic Scale score among patients diagnosed with bipolar affective disorder was 20.84 and that of the control group was 1.98. The proportion of thyroid dysfunction among bipolar affective disorder patients and among control group was 14% and 6% respectively. The odds ratio was calculated to be 2.55. Mean T3 values were higher in the bipolar affective disorder patients than the control group and this association was found to be statistically significant (p=0.031). Mean T4 and TSH values were higher among the bipolar affective disorder patients but did not show any significant differences when compared with the control group. CONCLUSION: The present study concludes that a statistically significant association exists between elevated T3 hormone and bipolar affective disorder and observes that the patients with bipolar affective disorder are 2.55 times more commonly associated with thyroid dysfunction.

Palmar dermatoglyphics in children with acute lymphoblastic leukemia--a preliminary investigation.

BACKGROUND: Acute lymphoblastic leukemia (ALL) is a malignant disease of as yet an unknown origin. Researchers in the past have studied the association between dermatoglyphic features in the hand and congenital diseases and diseases with genetic influences. OBJECTIVE: The present research is intended to study the association between acute lymphoblastic leukemia (ALL) and palmar dermatoglyphic characteristics to assess the value of dermatoglyphics as a screening tool to detect leukemia in high risk groups. METHODS: Case-control study conducted at the department of Pediatrics, KMC Attavara, a tertiary care teaching hospital of Kasturba Medical College, Mangalore (Manipal University), India during 2006. Twenty-four children suffering from acute lymphoblastic leukemia were included in the study. The dermatoglyhic features (ab- ridge count, atd, tda and dat angles) of their palm prints were compared with the age and sex matched controls. RESULTS: The present research indicates an association between dermatoglyphic features and ALL. The mean ab-ridge count, and the mean atd - angle were observed to be higher in cases while the mean tda - angle was found to be lower in cases than controls. CONCLUSIONS: The findings of the present research are suggestive of a possible trend and an association of dermatoglyphic features with children suffering from ALL. Similar studies can be useful in rare forensic case work where the association of dermatoglyphic features with certain diseases is to be explored.
