We report a case of an apparently healthy, immunocompetent individual who presented with headache and symptoms suggestive of raised intracranial pressure. Neurological imaging revealed marked edema in the basal ganglia. His history was remarkable for sustained contact with domestic felines. He was started on trimethoprim-sulphamethoxazole based on history, strongly positive serology, and radiological findings. He showed a marked response to treatment. The characteristic radiological findings, serology, and dramatic response to treatment confirmed the diagnosis in this case. A tissue diagnosis was not required in our case. This case highlights that immunocompetent individuals can develop neurological manifestations. Though cerebral toxoplasmosis is classically associated with multiple lesions, our case highlights that presentation as a solitary space-occupying lesion is also possible. Further research is needed to ascertain if prolonged exposure or extensive exposure is associated with severe manifestations.

4. Adrenal Hemorrhage

- Abstract
Adrenal hemorrhage is an uncommon disorder characterized by bleeding into the suprarenal glands. The hematoma may be unilateral or bilateral, and the clinical presentation can range from nonspecific abdominal pain to catastrophic cardiovascular collapse. The etiologies for this unusual disorder are diverse. Potential causes include blunt abdominal trauma, septicemia, coagulopathies, anti-coagulant use, pregnancy, stress, antiphospholipid syndrome, and essential thrombocytosis.[1][2][3][2][4][5][6][7] A high index of clinical suspicion is necessary for prompt diagnosis. A plethora of clinical presentations makes the diagnosis challenging. The signs and symptoms range from nonspecific abdominal pain to acute adrenal insufficiency, depending on the site and extent of hemorrhage. Imaging and biochemical evaluation provide the mainstay for diagnosis. The adrenal glands are a pair of endocrine organs located in the retroperitoneum on the upper poles of the kidneys. They comprise two embryologically and functionally distinct parts, the outer mesodermally derived adrenal cortex, which produces glucocorticoids, mineralocorticoids, and adrenal androgens, and the inner adrenal medulla, which originates from the neural crest secretes catecholamines. The suprarenal glands are one of the most well-perfused organs in the human body. The superior, middle, and inferior adrenal arteries originate from the inferior phrenic artery, the abdominal aorta, and the renal artery, respectively, form the chief arterial supply. In contrast, the venous drainage is limited and often utilizing a single adrenal vein, which drains into the inferior vena cava on the right and the renal vein on the left. This difference between the arterial inflow and venous drainage may explain the anatomic predisposition to developing hemorrhagic infarction.[8], (Copyright © 2021, StatPearls Publishing LLC.)

5. Ambiguous Genitalia And Disorders of Sexual Differentiation

- Abstract
The birth of an infant with ambiguous genitalia generates difficult multiple medical, surgical, ethical, psychosocial, and physical issues for patients and their parents. Phenotypic sex results from the differentiation of internal ducts and external genitalia under the influence of hormones and other additional factors. When discordance occurs among three processes (chromosomal, gonadal, phenotypic sex determination), a DSD is the result. Terminology, such as hermaphrodite, pseudo-hermaphrodite, and intersex, are considered to be pejorative and dated. These terms have been replaced by the term disorders of sexual development (DSD) by the consensus statement on the management of intersex disorders.[1][2] Disorders of sexual development are defined as congenital conditions characterized by atypical development of chromosomal, gonadal, or anatomic sex.[3] Normal sexual development in utero is dependent upon a precise and coordinated spatiotemporal sequence of various activating and repressing factors.[4] Any deviations from the usual pattern of differentiation can present as DSDs. Two distinct processes occur in normal sexual development. The first of which is sex determination, in which the bi-potential gonads are induced to form either the male testes or the female ovaries. Secondarily, the newly formed gonads secrete hormones to modulate the formation of internal and external genitalia.[5] The phenotypic manifestation of DSDs are diverse and can include; bilateral undescended testes, severe hypospadias (scrotal or perineal), clitoromegaly, a fusion of posterior labial folds, female external genitalia with palpable gonad, discordant genitalia, and sex chromosomes. The inclusion of disorders in which there is no genital/gonadal discordance like Turner syndrome, Klinefelter syndrome, simple hypospadias remains controversial. Regardless of presentation or severity, individuals require an interprofessional approach that is warranted to improve the quality of life and achieve the best possible outcomes., (Copyright © 2021, StatPearls Publishing LLC.)

- Abstract
Objective: To examine the prevalence, types and temporal trends of reported financial conflicts of interest (FCOIs) among authors of drug therapy randomized controlled trials (RCTs) for RA and their association with study outcomes., Methods: We identified original, non-phase 1, parallel-group, drug therapy RA RCTs published in the years 2002-03, 2006-07, and 2010-11. Two investigators independently obtained trial characteristics data. Authors' FCOIs were classified as honoraria/consultation fees receipt, employee status, research grant, and stock ownership. Multivariable logistic regression was performed to identify whether FCOIs were independently associated with study outcome., Results: A total of 146 eligible RCTs were identified. Of these, 83 (58.4%) RCTs had at least one author with an FCOI [employee status: 63 (43.2%), honoraria/consultation fees receipt: 49 (33.6%), research grant: 30 (20.5%), and stock ownership: 28 (19.2%)]. A remarkable temporal increase in reporting of honoraria/consultation fees receipt, research grant, and stock ownership was seen. The reporting of any FCOI itself was not associated with positive outcome [50/73 (68.5%) with author FCOI vs 36/52 (69.2%) without author FCOI, P = 0.93]. However, honoraria/consulting fees receipt was independently associated with increased likelihood of a positive outcome [adjusted odds ratio (95% CI) of 3.24 (1.06-9.88)]. In general, trials with FCOIs were significantly more likely to be multicentre, have larger enrolment, use biologic or a small molecule as the experimental intervention, and have better reporting of some methodological quality measures., Conclusion: FCOI reporting in RA drug RCT authors is common and temporally increasing. Receipt of honoraria/consulting fees was independently associated with a positive study outcome., (Published by Oxford University Press on behalf of the British Society for Rheumatology 2018.
