BACKGROUND AND AIMS
To compare ultra-sonographic dimensions of acoustic target window of the spine in the participants at four different sitting positions namely cross leg sitting (CLP), hamstring stretch (HSP), classical sitting (CSP) and riders sitting position (RSP). The primary objective of this study was to measure the neuraxial acoustic target window (defined as interlaminar distance between L3-L4 lamina). The secondary objective was to compare ultra-sonographic measurements of the depth of ligamentum flavum from the skin, and to compare the diameter of intrathecal space and comfort score in the four different sitting positions.
MATERIAL AND METHODS
This study is a prospective observational study. Eighty participants were included and positioned in four different sitting positions to perform an ultra-sonographic scan and measure various parameters of the acoustic neuraxial window. The interlaminar distance, the distance of skin from the ligamentum flavum, and the diameter of the spinal canal or intrathecal space was measured in the L3-L4 intervertebral space in different positions.
RESULTS
The mean value of interlaminar distance among four sitting positions was ranging from 1.40 cm to 1.44 cm ( value 0.725.) The distance of ligamentum flavum from skin and diameter of intrathecal space was also comparable in all the groups. The comfort score in CSP was significantly better when compared to other groups with a median score of 4 ( value < 0.001).
CONCLUSIONS
There is no statistically significant difference in interlaminar distance in various sitting positions. All four positions are equally effective and can be used as an alternative to spinal/epidural intervention, but the CSP came out to be the most comfortable and more emphasis should be given to the comfort as it increases the chance of success rate of the procedure.

BACKGROUND AND AIMS
Thoracic epidural insertion has high failure rates in the mid-thoracic region due to steep angulation of oblique bending of spinous processes. The preferred skin puncture point for epidural needle insertion in the paramedian sagittal plane with respect to the superior/inferior tip of spinous process or inter-spinous cleft in the mid-thoracic region (T5-8) is not standard. The primary objective of this prospective observational study was to find the skin puncture point which had the best success rate for a successful epidural catheterization. Secondary objectives were to study the number of attempts and passes required to locate epidural space, incidence of failed epidural, and its relationship with patient characteristics and demographics.
MATERIAL AND METHODS
After informed consent, 155 patients planned for general anesthesia with epidural analgesia in the mid-thoracic region were included in the trial. Patient demographics, the details of epidural attempts with respect to anatomical landmarks, distance from the midline, and number of passes in each attempt were noted. Epidural catheterization was considered successful after demonstrating dermatomal band of sensory blockade.
RESULTS
The success rate at different skin puncture sites was not statistically significant ( = 0.58). We found a failure rate of 12.9%. Failed epidural catheterization was significantly high in the age group >56 years ( = 62 and = 0.007).
CONCLUSION
In our study, none of the skin puncture points had a significant association with successful epidural insertion in mid-thoracic segments using a para-median approach.

Distal bypass surgery's effect on tissue blood pressure beyond a focal angiosome remains debated. This study assessed tissue blood pressure in both direct revascularized angiosome (DRA) and indirect revascularized angiosome (IRA) after bypass surgery, utilizing repeated skin perfusion pressure (SPP) measurements. Twenty-nine limbs in 27 chronic limb-threatening ischemia (CLTI) patients (22 males and five females, age: 70.2 ± 9.3 years) who received distal bypass surgery were enrolled. SPP measurements were conducted for the DRA and IRA at 10 time intervals, encompassing both preoperative and postoperative periods of every 3-5 days until 30 days. In total, 486 SPP measurements were collected from 58 measurement sites, and the transition of the SPP at the DRA was 35.4-62.5-59.5-70.2-58.2-62.2-63.1-63.6-63.8-73.4 mmHg and IRA was 29.4-53.4-53.7-58.8-51.3-63.1-47.9-62.1-57.6-61.0 mmHg. No significant differences were observed between SPP at the DRA and IRA. Fifteen wounds on the DRA (63%) and five on the IRA (100%) healed. Distal bypass improves SPP in both direct and IRAs of CLTI patients. These data indicated distal bypass improves tissue blood flow at entire foot regardless of angiosomes.

Review
Lymphedema is caused by dysfunction of the lymphatic system. It is divided into primary edema with no apparent cause and secondary edema with an exogenous cause. The main symptoms are edema and heaviness, skin changes such as skin hardening, lymphocysts, lymphorrhoea, papillomas, and recurrent cellulitis. They are often irreversible and progressive, thus greatly reducing quality of life of the patients. Diagnosis is made by image examinations that can evaluate lymphatic flow and functions such as lymphoscintigraphy and indocyanine green fluorescence lymphangiography. Linear pattern and dermal backflow are the main findings. Conservative treatment consists of four components: compression therapy with elastic garments, exercise therapy, manual lymphatic drainage, and skin care, which is called complex physical therapy (CPT). Although CPT has become the gold standard of treatment, with evidence of efficacy reported in terms of volume reduction, maintenance, and prevention of cellulitis, it is a symptomatic treatment and does not improve impaired lymphatic flow. On the other hand, surgical treatment, such as lymphaticovenous anastomosis and vascularized lymph node transplantation, can create new lymphatic flow and improve lymphatic dysfunctions. Although these techniques are expected to be effective in volume reduction, cellulitis prevention, and improving quality of life, there is a need for more studies with a higher level of evidence in the future. In Japan, lymphedema is treated with a combination of conservative and surgical therapies, but lymphedema is intractable and few cases are completely cured. Therefore, how to improve the outcome of treatment is an important issue to be addressed in the future. (This is a translation of Jpn J Vasc Surg 2023; 32: 141-146.).

Randomized Controlled Trial
The effectiveness and safety of 3% tranexamic acid cream vs. 4% hydroquinone cream for mixed-type melasma in skin of color: a double-blind, split-face, randomized controlled trial.
INTRODUCTION
Melasma, a chronic acquired skin pigmentation disorder, is characterized by the presence of irregular-edged brown to gray-brown patches with a symmetrical distribution, primarily on sun-exposed areas such as the face. Topical hydroquinone (HQ) is the gold standard for melasma treatment but has numerous side effects. This study assesses the effectiveness of topical tranexamic acid (TA) as an alternative for melasma treatment.
METHODS
In a double-blind, split-face, randomized controlled trial involving 20 subjects, the effectiveness of 3% TA versus 4% HQ cream was evaluated over 8 weeks. The modified melasma area and severity index (mMASI), melanin index, erythema index, and side effects were assessed. Subjective improvement was measured using the patient global assessment (PtGA).
RESULTS
A significant decline in the mMASI score was observed at weeks 4 and 8 in both groups compared to baseline. There were no statistically significant differences in PtGA scores between the 3% TA group and the 4% HQ group.
CONCLUSIONS
Topical 3% TA is as effective and safe as 4% HQ for treating melasma in the Indonesian population, with potential advantages in terms of side-effect profiles.

BMC Pediatrics Jun 2024Early-onset sepsis (EOS) is a serious illness that affects preterm newborns, and delayed antibiotic initiation may increase the risk of adverse outcomes.
BACKGROUND
Early-onset sepsis (EOS) is a serious illness that affects preterm newborns, and delayed antibiotic initiation may increase the risk of adverse outcomes.
PURPOSE
The objective of this study was to examine the present time of antibiotic administration in preterm infants with suspected EOS and the factors that contribute to delayed antibiotic initiation.
METHODS
In this retrospective study in China, a total of 82 early preterm infants with suspected EOS between December 2021 and March 2023 were included. The study utilized a linear regression analytical approach to identify independent factors that contribute to delayed antibiotic administration.
RESULTS
The mean gestational age and birth weight of the study population were 29.1 ± 1.4 weeks and 1265.7 ± 176.8 g, respectively. The median time of initial antibiotic administration was 3.8 (3.1-5.0) hours. Linear regression revealed that severe respiratory distress syndrome (RDS) (β = 0.07, P = 0.013), penicillin skin test (PST) timing (β = 0.06, P < 0.001) and medical order timing (β = 0.04, P = 0.017) were significantly associated with the initial timing of antibiotic administration.
CONCLUSIONS
There is an evident delay in antibiotic administration in preterm infants with suspected EOS in our unit. Severe RDS, PST postponement and delayed medical orders were found to be associated with the delayed use of antibiotics, which will be helpful for quality improvement efforts in the neonatal intensive care unit (NICU).

Randomized Controlled Trial Comparative Study
A Randomized Single-Blinded Phase II Trial Comparing Efficacy and Quality of Life of Topical Aloe Vera Gel Plus Urea Cream Versus Urea Cream Alone for Prevention of Hand Foot Syndrome in Cancer Patients Receiving Capecitabine.
INTRODUCTION
Capecitabine has been widely prescribed to treat various cancers. The hand foot syndrome (HFS) is the most troublesome adverse effect. Urea cream has been pre-emptively co-prescribed, even though its efficacy is doubtful. Aloe vera gel with urea cream might potentiate each other. This trial was intended to prove the efficacy of this combination.
MATERIALS AND METHODS
The investigators conducted a randomized single-blinded phase II study. The participants were randomized 1:1 to receive the combination of aloe vera gel and 10% urea cream (n = 30), the experimental A+U arm and 10% urea cream alone (n = 31), the U arm. The sample size was calculated to have 90% power to show the significant 20% reduction in the incidence of HFS grade 2-3 of the combination therapy with alpha level = 0.05. Both the CTCAE criteria version 5 and the dermatology life quality index (DLQI) were assessed to determine the severity of HFS and quality of life, respectively.
RESULTS
Most of the participants had rectal cancer (A+U: 43.3%; U: 41.9%). In the A+U group, 86.7% had grade 0-1 HFS and 13.3% had grade 2-3 HFS. In the U group, 64.5% had grade 0-1 HFS and 35.5% had grade 2-3 HFS (Mann-Whitney U test, p = 0.045). Grade 2-3 HFS was significantly lower in the combination group.
CONCLUSION
Combination of aloe vera gel and 10% urea cream ameliorated the severity of HFS in participants taking capecitabine; however, no significant difference in DLQI between the groups was demonstrated.

Cutaneous leishmaniasis (CL) is a neglected disease caused by Leishmania parasites. The oral drug miltefosine is effective, but there is a growing problem of drug resistance, which has led to increasing treatment failure rates and relapse of infections. Photodynamic therapy (PDT) combines a light source and a photoactive drug to promote cell death by oxidative stress. Although PDT is effective against several pathogens, its use against drug-resistant Leishmania parasites remains unexplored. Herein, we investigated the potential of organic light-emitting diodes (OLEDs) as wearable light sources, which would enable at-home use or ambulatory treatment of CL. We also assessed its impact on combating miltefosine resistance in Leishmania amazonensis-induced CL in mice. The in vitro activity of OLEDs combined with 1,9-dimethyl-methylene blue (DMMB) (OLED-PDT) was evaluated against wild-type and miltefosine-resistant L. amazonensis strains in promastigote (EC = 0.034 μM for both strains) and amastigote forms (EC = 0.052 μM and 0.077 μM, respectively). Cytotoxicity in macrophages and fibroblasts was also evaluated. In vivo, we investigated the potential of OLED-PDT in combination with miltefosine using different protocols. Our results demonstrate that OLED-PDT is effective in killing both strains of L. amazonensis by increasing reactive oxygen species and stimulating nitric oxide production. Moreover, OLED-PDT showed great antileishmanial activity in vivo, allowing the reduction of miltefosine dose by half in infected mice using a light dose of 7.8 J/cm and 15 μM DMMB concentration. In conclusion, OLED-PDT emerges as a new avenue for at-home care and allows a combination therapy to overcome drug resistance in cutaneous leishmaniasis.

Comparative Study
This retrospective study investigates the efficacy of 2 treatment regimens, pregabalin alone versus pregabalin combined with ketamine, amitriptyline, and lidocaine cream, in reducing itch in patients with brachioradial pruritus at a tertiary care center. Electronic medical records of 64 brachioradial pruritus patients seen at the University of Miami Itch Center were analyzed. A significant reduction in itch scores was seen with both treatments, with no significant difference between the groups. A small number of patients experienced adverse effects, including drowsiness and weight gain with pregabalin and skin irritation with ketamine, amitriptyline, and lidocaine cream. Ultimately, our findings underscore the potential of utilizing combined therapy for difficult-to-treat brachioradial pruritus cases and implementing individualized approaches for managing neuropathic pruritus. Further controlled clinical trials are needed to establish optimal treatment protocols.

Randomized Controlled Trial
BACKGROUND
Patients with advanced pancreatic cancer have -limited survival and few treatment options. We studied whether mistletoe extract (ME), in addition to comprehensive oncological treatment and palliative care, prolongs overall survival (OS) and -improves health-related quality of life (HRQoL).
METHODS
The double-blind, placebo-controlled MISTRAL trial was conducted in Swedish oncology centers. The main inclusion criteria were advanced exocrine pancreatic cancer and Eastern Cooperative Oncology Group (ECOG) performance status 0-2. The subjects were randomly assigned to ME (n=143) or placebo (n=147) and were stratified by study site and by eligibility (yes/no) for palliative chemotherapy (June 2016-December 2021). ME or placebo was injected subcutaneously three times a week for nine months. The primary endpoint was overall survival (OS); one of the secondary endpoints was the HRQoL dimension global health/QoL (EORTC-QLQ-C30), as assessed at seven time points over nine months. Trial registration: EudraCT 2014-004552-64, NCT02948309.
RESULTS
No statistically significant benefit of adding ME to standard treatment was seen with respect to either OS or global health/QoL. The adjusted hazard ratio for OS was 1.13 [0.89; 1.44], with a median survival time of 7.8 and 8.3 months for ME and placebo, respectively. The figures for the HRQoL dimension "global health/QoL" were similar in the two groups (p=0.86). The number, severity, and outcome of the reported adverse events were similar as well, except for more common local skin reactions at ME injection sites (66% vs. 1%).
CONCLUSION
ME is unlikely to have a clinically significant effect on OS or the HRQoL dimension global health/QoL when administered in patients with advanced pancreatic cancer in addition to comprehensive cancer care.
