Introduction: Isotretinoin is a widely used, effective medication for moderate to severe acne. It is typically used for several months, which necessitates regular laboratory monitoring. However, consensus on the optimal assessment frequency is lacking., Method: This is a single-center retrospective study on 1182 patients who received isotretinoin for acne at the Dermatology Clinic in Jordan University Hospital over 5 years., Results: Of the 1182 patients, 892 (76.57% females) met the inclusion criteria. An increase in the proportion of patients with abnormal triglycerides and total cholesterol levels from baseline to the sixth month was observed ( p  < 0.05). Conversely, differences in the number of patients with abnormal AST, ALT, and CBC were not found throughout treatment ( p  > 0.05). Moreover, there was a decrease in the neutrophil-to-lymphocyte ratio (NLR) ratio and systemic inflammatory index (SII) after the sixth month of isotretinoin treatment compared to the baseline ( p  = 0.012 and p  = 0.021, respectively)., Conclusions: We found that a baseline cholesterol level of 163.9 mg/dl and a baseline triglycerides level of 85.5 mg/dL are highly specific and sensitive in detecting grade 1 abnormalities at the one-month follow-up. This novel prediction approach serves as an effective risk stratification method for isotretinoin acne patients.

BACKGROUND Splenic cysts are classified as either parasitic or non-parasitic cysts, with both types sharing similarities in their clinical presentation and imaging findings. Most splenic cysts are of parasitic origin, while non-parasitic splenic cysts are less common. Splenic epidermoid cysts (SECs) are a rare subtype of non-parasitic cysts and compromise only around 10% of them. CASE REPORT In this paper we present a case of 22-year-old man with no significant past clinical history, who presented with non-specific, vague symptoms, including persistent left upper-quadrant pain and discomfort for the last 2 years. A physical examination and extensive laboratory tests were inconclusive. Subsequently, the patient underwent multiple imaging studies including ultrasonography and computed tomography (CT) scan of the abdomen. His ultrasonographic findings were consistent with the diagnosis of hydatid cyst, which was further emphasized by its frequent occurrence in clinical practice, as our country is considered an endemic region. In light of this, he underwent laparoscopic splenectomy following percutaneous cyst drainage. The consequent histopathological examination revealed the diagnosis of splenic epidermoid cysts. CONCLUSIONS When encountering splenic cysts in regions where parasitic infections are endemic, special attention is needed, as physical examination, laboratory tests, and imaging studies alone are insufficient to differentiate among the types of cysts. Histopathological examination remains the diagnostic tool of choice, particularly when imaging findings are inconclusive. Splenectomy, with either a laparoscopic or open approach, is the treatment of choice for splenic cysts to prevent recurrence as well as other potential catastrophic complications.
