Acute generalized exanthematous pustulosis due to ceftriaxone: Report of a pediatric case with recurrence after positive patch test

Acute generalized exanthematous pustulosis (AGEP) is seen uncommonly in children and sometimes shows atypical clinical features in this population. Patch testing can be used effectively in children for the confirmation of the culprit drug in cases of multiple drug use. Here, we report a rare, pediatric case of ceftriaxone‐induced AGEP confirmed by patch testing with subsequent recurrence of the skin eruption.     

Facile synthesis of novel 3D flower-like magnetic La@Fe/C composites from ilmenite for efficient phosphate removal from aqueous solution

In this study, a novel 3D flower-like La@Fe/C magnetic composite was successfully synthesized by carbothermal reduction of ilmenite via microwave radiation. The physico-chemical properties of the composite were investigated. The results showed that La@Fe/C features a 3D flower-like morphology with an S_BET and V_mic of 114 m² g⁻¹ and 0.017 cm³ g⁻¹, respectively. Zerovalent iron and metal oxides were detected by XRD and XPS on the surface of the adsorbent, which formed as a result of carbothermal reduction of ilmenite using coconut shell-based carbon followed by the introduction of lanthanum. This resultant magnetic La@Fe/C exhibited remarkable phosphate selectivity performance even in the presence of a 50-fold excess of competing ions, which is superior to the pristine ilmenite and coconut activated carbon. Adsorption isotherms and adsorption kinetics fitted well with the Langmuir model and pseudo-second-order model, respectively. A thermodynamic study indicated that the adsorption of phosphate was spontaneous and endothermic. The adsorption–regeneration cyclic experiments of the La@Fe/C composite demonstrated a good level of recyclability. These results indicated that carbothermal reduction of ilmenite followed by the introduction of lanthanum could result in highly efficient and recoverable magnetic particles for the removal of phosphate from wastewater.

In this study, a novel 3D flower-like La@Fe/C magnetic composite was successfully synthesized by carbothermal reduction of ilmenite via microwave radiation.     

Constricting wide abdominal burn scar and pregnancy

Abdominal burn scars and pregnancy are rare in literature. Loss of normal skin ability to stretch, scar-related uterine displacement, and maternal discomfort especially on the second half of pregnancy are the main problems. We present a case report of pregnancy with an abdominal burn scar due to scalded burn injury. Although the abdominal scar was constricting the abdominal wall severely, intensive follow-up of the pregnancy culminated in a healthy newborn via cesarean. There was enough expansion over the abdominal wall including the scar for a healthy delivery without any need for an operation. Level of Evidence: Level V, therapeutic study.     

Serum bcl-2 and survivin levels in melanoma

This study was conducted to investigate the serum levels of bcl-2 and survivin in patients with melanoma and the relationship with tumour progression and known prognostic parameters. Forty-four patients with cutaneous melanoma were investigated. Serum samples were obtained on first admission before adjuvant and metastatic treatment were given and at follow-up. Serum bcl-2 and survivin levels were determined using enzyme immunometric assay (EIA) and enzyme-linked immunosorbent assay (ELISA). The baseline serum bcl-2 levels were significantly higher in patients with melanoma than in the control group (P=0.01). For the serum survivin levels, no difference was found (P=0.6). No significant correlations were found between the prognostic parameters analysed and the serum survivin concentrations. The same was true of the serum bcl-2 values, except for the age of the patient (P=0.025) and nodal involvement (P=0.003). No significant relationship was found between the serum levels of bcl-2 and survivin (r=-0.13, P=0.4). In node-positive patients (n=8) both of these anti-apoptotic substances were unchanged after interferon-alpha-2b therapy. However, serum survivin concentrations were significantly increased in 10 patients with metastatic melanoma who underwent dacarbazine (DTIC)-based cytotoxic chemotherapy (P=0.047). A similar finding was not determined for the serum bcl-2 levels. In conclusion, the results of this study suggest that decreased apoptosis is associated partly with an increase in serum bcl-2. However, much research continues in this field, and exciting new knowledge will ultimately emerge.     

Safety of paclitaxel in a patient with ovarian cancer and hyperbilirubinemia due to Rotor's syndrome

BACKGROUND: Rotor's syndrome is a rare congenital disorder characterized by functional hyperbilirubinemia. Treatment decision may be challenging in a cancer patient with Rotor's syndrome, since the majority of the antineoplastic agents are metabolized in the liver and excreted via the biliary system. We report the first case of paclitaxel administration in a patient with ovarian cancer and elevated bilirubin levels due to Rotor's syndrome. CASE: A 50-year-old woman with Rotor's syndrome had an exploratory laparotomy and was diagnosed to have stage IIIC epithelial ovarian cancer. The baseline serum bilirubin value was 15.3 mg/dL. She was started on a 50% dose of 87.5 mg/m(2) paclitaxel by 3-h infusion plus carboplatin AUC-6. The paclitaxel dose was increased by 25% at consecutive cycles until the standard dose of 175 mg/m(2)/3 h was achieved. Six cycles were administered without any metabolic derangement. The patient was rendered disease free with this treatment. CONCLUSION: Paclitaxel appears to be safe to administer to cancer patients with functional hyperbilirubinemia.     

Color doppler imaging in glaucoma patients with asymmetric visual field loss

With color Doppler imaging, we attempted to determine whether glaucoma patients with asymmetric visual field losses had evidence of asymmetric blood flow velocities in the central retinal artery despite similar intraocular pressure (IOP) curves in both eyes. We found that eyes with more severe visual field damage had an increased local resistance to blood flow in the central retinal artery. Thus vascular factors might have important roles in the pathogenesis of primary open-angle glaucoma.
