RESUMEN
BACKGROUND: Manipulation of the temporalis muscle during pterional and frontotemporal approaches poses major cosmetic and functional issues postoperatively. The temporalis muscle has usually been secured in its normal position using implants or by leaving a thin rim of muscle and fascia attached along the superior temporal line. In the present report, we have described a pure tissue-based method of anchoring the intact temporalis muscle precisely along the superior temporal line. METHODS: A total of 30 consecutive cases of pterional or frontotemporal craniotomy were performed by single surgeon (SKR). A subfascial dissection technique was used to expose the transition zone of the frontal pericranium with the temporalis fascia. These were then separated by sharp dissection along the superior temporal line at which the muscle is attached. The temporalis muscle and fascia were repositioned during closure, precisely at their original anatomical location by passing multiple anchoring sutures along the free edge of the muscle and fascia lying along the superior temporal line. RESULTS: Temporalis muscle reattachment was achieved in all 30 cases with good cosmesis and functional outcome without temporalis muscle-related complications at 6 months of follow-up. CONCLUSIONS: The approximation of sutures running through the free edge of the temporalis muscle with intact fascia along the superior temporal line from anteriorly to posteriorly restored the muscle and fascial layer to its original position. Avoidance of the formation of any potential dead space during surgical exposure will prevent periorbital edema and/or subgaleal collection postoperatively. The described inexpensive technique avoids implant-related complications, with good functional and aesthetic outcomes. A comparative study is needed to establish the superiority of this procedure over other techniques.

Here, we report a case of Acute promyelocytic leukemia (APL) with three way complex translocation involving chromosomes 4, 15, and 17. Although chromosome 4 is most commonly associated chromosome in three way translocation, present case is the first report with four novel co-existent findings of new break point region on chromosome 4, new cyclic mechanism with simultaneous breaks, presence of a co-existent tetrasomy 8 and FLT3 ITD positivity.; Comprehensive assessment highlight the utility of combining morphology, immunophenotyping, karyotyping, fluorescence in situ hybridization, and molecular studies for better characterization, optimal management of APL with a better understanding of the pathogenic mechanism and prognosis of the disease.

BACKGROUND: Currently, there is no specific drug for the treatment of coronavirus disease 2019 (COVID-19). Therapeutic benefits of intravenous immunoglobulin (IVIG) have been demonstrated in wide range of diseases. The present study is conducted to evaluate the safety and efficacy of IVIG in the treatment of COVID-19 patients with moderate pneumonia. METHODS: An open-label, multicenter, comparative, randomized study was conducted on COVID-19 patients with moderate pneumonia. One hundred eligible patients were randomized in 1:1 ratio either to receive IVIG + standard of care (SOC) or SOC. RESULTS: Duration of hospital stay was significantly shorter in the IVIG group compared with that of SOC alone (7.7 vs 17.5 days). Duration for normalization of body temperature, oxygen saturation, and mechanical ventilation were significantly shorter in IVIG compared with SOC. Percentages of patients on mechanical ventilation in 2 groups were not significantly different (24% vs 38%). Median time to reverse-transcription polymerase chain reaction negativity was significantly shorter with IVIG than SOC (7 vs 18 days). There were only mild to moderate adverse events in both groups except for 1 patient (2%), who died in SOC. CONCLUSIONS: Intravenous immunoglobulin was safe and efficacious as an adjuvant with other antiviral drugs in the treatment of COVID-19.

Determination of the magnitude of body iron stores helps to identify individuals at risk of iron-induced organ damage in Thalassemia patients. The most direct clinical method of measuring liver iron concentration (LIC) is through chemical analysis of needle biopsy specimens. Here we present a noninvasive method for the measurement of LIC in vivo using magnetic resonance imaging (MRI). Twenty-three pediatric Thalassemia major patients undergoing bone marrow transplantation at our centre were studied. All 23 patients had MRI T2* and R2* decay time for evaluation of LIC on a 1.5 Tesla MRI system followed by liver tissue biopsy for the assessment of iron concentration using an atomic absorption spectrometry. Simultaneously, serum ferritin levels were measured by enzymatic assay. We have correlated biopsy LIC with liver T2* and serum ferritin values with liver R2*. Of the 23 patients 11 were males, the mean age was 8.3 ± 3.7 years. The study results showed a significant correlation between biopsy LIC and liver T2* MRI (r = 0.768; p < 0.001). Also, there was a significant correlation between serum ferritin levels and liver R2* MRI (r = 0.5647; p < 0.01). Two patients had high variance in serum ferritin levels (2100 and 4100 mg/g) while their LIC was around 24 mg/g, whereas the difference was not seen in T2* MRI. Hence, the liver T2* MRI is a better modality for assessing LIC. Serum ferritin is less reliable than quantitative MRI. The liver T2* MRI is a safe, reliable, feasible and cost-effective method compared to liver tissue biopsy for LIC assessment.
