The particular Mixed Aftereffect of Tropicamide and Phenylephrine in Cornael Astigmatism Axis.
Cutaneous mucormycosis caused by Mucor irregularis (M. FX11 ic50 irregularis) is a rare condition that typically occurs in immunocompetent patients. Herein, we describe an immunocompromised patient with cutaneous M. irregularis infection who was successfully treated with debridement combined with vacuum assisted closure (VAC) negative pressure technique and split-thickness skin grafting. We present this case owing to its complexity and rarity and the successful treatment with surgical therapy. A 58-year-old man presented to our hospital with a history of skin ulcers and eschar on the right lower leg since two months. He had been receiving methylprednisolone therapy for bullous pemphigoid that occurred five months prior to the present lesions. Histopathological examination of a right leg lesion showed broad, branching hyphae in the dermis. Fungal culture and subsequent molecular cytogenetic analysis identified the pathogen as M. irregularis. After admission, methylprednisolone was gradually tapered and systemic treatment with amphotericin B (total dose 615 mg) initiated along with others supportive therapies. However, the ulcers showed no improvement, and amphotericin B had to be discontinued owing to development of renal dysfunction. After extensive surgical debridement combined with VAC and skin grafting, his skin ulcers were healed; subsequent fungal cultures of the lesions were negative. The patient exhibited no signs of recurrence at 36-month follow-up. Twenty-six cases with M. irregularis-associated cutaneous mucormycosis in literature were reviewed.
Morbidity and mortality from serious infections are common in intensive care units(ICUs). The appropriateness of the antibiotic treatment is essential to combat sepsis. We aimed to evaluate pharmacokinetic/pharmacodynamic target attainment of meropenem and piperacillin/tazobactam administered at standard total daily dose as continuous infusion in critically ill patients without renal dysfunction and to identify risk factors of non-pharmacokinetic/pharmacodynamic target attainment.

We included 118 patients (149 concentrations), 47% had microorganism isolation. Minimum inhibitory concentration (MIC)[median (interquartile range, IQR) values in isolated pathogens were meropenem 0.05 (0.02-0.12) mg/l; piperacillin 3 (1-4) mg/l]. Pharmacokinetic/pharmacodynamic target attainments (100%fC
, 100%fC
and 100%fC
, respectively) were 100%, 96.15%, 96.15% (meropenem) and 95.56%, 91.11%, 62.22% (piperacillin) for actual MIC; 98.11%, 71.70%, 47.17% (meropenem, MIC 2 mg/l), 95.83%, 44.79%, 6.25% (piperacillin, MIC 8 mg/l), 83.33%, 6.25%, 1.04% (piperacillin, MIC 16 mg/l) for EUCAST breakpoint of Enterobacteriaceae spp. and Pseudomonas spp. Multivariable linear analysis identified creatinine clearance (CrCL) as a predictive factor of free antibiotic concentrations (fC
) of both therapies (meropenem [β = - 0.01 (95% CI - 0.02 to - 0.0; p = 0.043)] and piperacillin [β = - 0.01 (95% CI - 0.02 to 0.01, p < 0.001)]). Neurocritical status was associated with lower piperacillin fC
[β = - 0.36 (95% CI - 0.61 to - 0.11; p = 0.005)].

Standard total daily dose of meropenem allowed achieving pharmacokinetic/pharmacodynamic target attainmentsin ICU patients without renal dysfunction. Higher doses of piperacillin/tazobactam would be needed to cover microorganisms with MIC > 8 mg/l. CrCL was the most powerful factor predictive of fC
in both therapies.
8 mg/l. CrCL was the most powerful factor predictive of fCss in both therapies.
Maintaining standards of living donor liver transplantation (LDLT) can be a challenge during the corona virus disease 2019 (COVID-19) pandemic. Center-specific protocols have been developed and transplant societies propose limiting elective LDLT. We have looked at outcomes of LDLT during the pandemic in an exclusively LDLT center.

Patients were grouped into pre-COVID (January 2019-February 2020) (n = 162) and COVID (March 2020-January 2021) (n = 53) cohorts. We looked at patient characteristics, 30-day morbidity, and mortality. Outcomes were also assessed in donors and recipients who underwent surgery after recovery from COVID-19.

The average number of transplants reduced from 11.5/month to 4.8/month. Fewer patients with MELD > 20 underwent LDLT in the COVID cohort (41.3% versus 24.5%, P = 0.03). Out of nine patients with a positive pretransplant COVID-19 PCR, there were 2 (22.3%) deaths on the waiting list. Seven patients underwent LT after recovery from COVID-19 with one 30-day mortality due to biliary sepsis. Three donors with positive COVID-19 PCR underwent uneventful donation after testing negative for COVID-19. No significant difference in 30-day survival was observed in the pre-COVID and COVID cohorts (93.2% versus 90.6%) (P = 0.3). Out of two recipients who developed COVID-19 pneumonia within 30 days after LT, there was one mortality. The 1-year survival for the entire cohort with a MELD cutoff of 20 was 90% and 84% (P = 0.2).

Despite comparable outcomes, fewer sick patients might undergo LDLT during the pandemic. Individuals recovered from COVID-19 might be safely considered for donation or transplantation.

The data on surgical outcomes of esophagectomy in patients with achalasia is limited. We sought to evaluate surgical outcomes in achalasia patients after an esophagectomy versus non-achalasia patients to elucidate if the outcomes are affected by the diagnosis.

We conducted a retrospective review of the National Surgical Quality Improvement Program database (2010-2018). Patients who underwent an esophagectomy (open or laparoscopic approach) were included. Patients were divided into two groups, achalasia vs non-achalasia patients, and matched using propensity match analysis.

Of the 10,997 esophagectomy patients who met inclusion criteria, 213 (1.9%) patients had a diagnosis of achalasia. A total of 418 patients were included for the final analysis, with 209 patients in each group (achalasia vs non-achalasia). The overall median age was 57 years (IQR 47-65 years), and 48.6%were female. Most underwent an open (93.1%) vs laparoscopic (6.9%) esophagectomy. Overall complication rate was 40%. No difference was identified on overall complications, readmission, reoperation, or mortality between both groups.
