05, GM decrease from baseline ≥33%). At week 24, IL-17A and IL-17F levels were not significantly different from HCs, suggesting normalisation of peripheral IL-23/Th17 axis effector cytokines postguselkumab treatment. Reductions in IL-17A/IL-17F levels were greater in guselkumab-treated versus ustekinumab-treated participants, whereas effects on CRP levels were similar.
 
  Guselkumab treatment reduced serum protein levels of acute phase and Th17 effector cytokines and achieved comparable levels to those in HCs. In participants with PsA, reductions of IL-17A and IL-17F were of greater magnitude after treatment with guselkumab than with ustekinumab.

Nature of the mass determines the degree of attenuation both in unenhanced and in different phases of contrast enhancement. Benign neurogenic tumours like ganglioneuroma mimicks pheochromocytoma and adrenocortical carcinoma in non-contrast CT scan. The 'adrenal protocol' routinely calculates the wash-out pattern at delayed venous phase (DVP) (15 min) following contrast administration to differentiate majority of benign masses from the malignant ones. Ganglioneuromas typically exhibit continuous wash-in of contrast where enhancement gradually increases to attain its peak in DVP. Such wash-in pattern is different from the wash-out pattern observed in pheochromocytomas or adrenocortical adenomas or carcinomas. Presence of this wash-in pattern provides a useful clue to the clinician for underlying ganglioneuroma in hormonally inactive adrenal masses with suspicious morphological appearances. This wash-in pattern also effectively rules out any malignant potential of ganglioneuroma, and thus helps in preoperative decision-making.Familial Mediterranean fever (FMF) is an autoinflammatory disease caused by a pyrin dysfunction, leading to uncontrolled interleukin-1 production that triggers the attacks. Here we report a case of a 36-year-old female patient repeatedly admitted to the cardiology ward with recurrent episodes of pericarditis, with intervals of 1 and 2 months between the episodes. During the attacks, chest pain and fever were the only symptoms. Following the administration of steroids and non-steroidal anti-inflammatory drugs, the patient became afebrile. She also had lymphoma and thyroid carcinoma in anamnesis essential for differential diagnosis. Laboratory tests for infection and autoimmune disease were all negative, and the positron emission tomography-CT scan did not reveal lymphoma relapse. Genetic testing revealed a mutation in the MEFV gene. It is very rare for pericarditis to be the first and only manifestation of FMF.Subglottic haemangioma presents as progressive obstruction in the neonatal and infantile airway, with a soft lesion seen during endoscopy. Diagnosis is based on macroscopic findings, biopsy is not usually performed and propranolol is first-line treatment. In contrast, ectopic thymus is a rare differential diagnosis for subglottic mass made by histopathological examination after excision or autopsy. In this article, we present a case of an infant with a subglottic lesion with endoscopic features consistent with haemangioma. After initial clinical response to propranolol, the patient represented with progressive stridor no longer responding to therapy. Open excision of the lesion was performed, and histopathology revealed ectopic thymus tissue. In this case, ectopic thymus tissue mimicked the presentation of subglottic haemangioma, and confirmation bias persisted due to an apparent initial clinical response to treatment with propranolol. In cases of subglottic mass refractory to medical treatment, excision of the lesion should be considered.Retinitis pigmentosa can be associated with exudative vasculopathy in rare instances, which can manifest as retinal vasoproliferative tumours. We present the case of a 33-year-old woman previously diagnosed with retinitis pigmentosa sine pigmentosa in both eyes. She was asymptomatic and just came in for a routine follow-up eye examination. Thorough examination of the peripheral retina on the right eye revealed a dome-shaped retinal tumour with a feeder vessel and surrounding exudative changes at the superotemporal periphery, consistent with a secondary retinal vasoproliferative tumour from retinitis pigmentosa. She subsequently underwent focal laser photocoagulation of the tumour which resulted in tumour stabilisation. While exudative vasculopathy is very uncommon in retinitis pigmentosa, ophthalmologists need to be aware of its occurrence in such patients. Vision loss may occur from exudation, haemorrhage, retinal detachment and neovascularisation. A thorough examination of the peripheral retina is warranted in these cases.An 8-month-old male child presented with the complaint of two separate urinary streams from the penis. The child had no complaints of incontinence or recurrent UTI (urinary tract infection). Initial diagnosis of urethrocutaneous fistula was made and proceeded to micturating cystourethrography (MCU) and found to be having a urethral duplication. The duplicated urethra was excised and accessory urethra closed.  https://www.selleckchem.com/products/skf38393-hcl.html  Postoperatively, the child was followed up for 1 year and had no complaints of recurrence or incontinence. Through this case report, we learn about different classification systems and types of urethral duplication and their associated anomalies, and mode of management, which is mainly surgical. Further, management should be individualised to each patient based on their complaints and intraoperative findings.In utero exposure to angiotensin II receptor blockers (ARBs) has fetotoxic effects including renal failure, oligohydramnios and lung hypoplasia. We present the case of a 24-year-old woman who presented to the maternity services in the 34th week of her first pregnancy. She was taking valsartan for hypertension. Ultrasound showed a structurally normal fetus with anhydramnios. The patient was admitted and valsartan was discontinued. She had spontaneous preterm delivery at 35 weeks' gestation of a baby girl. The baby's urine output was minimal in the first week of life and she was transferred to a paediatric hospital for specialist nephrology input. At 6 months of age, she requires ongoing nephrology follow-up and she remains on treatment for hypertension and anaemia. This case demonstrates the serious adverse effects resulting from ARB exposure in utero, and highlights the importance of avoiding fetotoxic medications in women of childbearing age.
