Bilateral anterior fracture-dislocations of humeral neck in a patient with seizure are extremely rare. We describe a rare case of a 33 -year-old Chinese gentleman who presented post seizure secondary to subdural gliosis, sequelae from a previous subdural haematoma. Following physical examination and radiographic assessment, including a Computed Tomography scan (CT scan), Rarely fracturedislocation of bilateral proximal humeri were diagnosed; similar fracture patterns were noted. Open reduction and internal fixation with PHILOS proximal humeral locking plate allowed early shoulder rehabilitation.

Congenital adrenal hyperplasia is an uncommon diagnosis in routine clinical practice. 21-hydroxylase deficiency, which is its most common subtype, may be diagnosed at birth in a female infant by virilisation or by features of salt wasting in both genders. However, other uncommon subtypes of this condition such as 17-alpha-hydroxylase deficiency, 11-beta-hydroxylase deficiency may present much later in adolescence or adulthood. A high index of suspicion is necessary when evaluating children with hypertension, hypokalaemia, metabolic alkalosis or sexual infantilism.

Malaria is a life-threatening disease caused by the Plasmodium sp. parasite.
Infection results in heightened pro-inflammatory response which contributes to the
pathophysiology of the disease. To mitigate the overwhelming cytokine response, host-directed
therapy is a plausible approach. Glycogen synthase kinase-3β (GSK3β), a serine/threonine
kinase plays a pivotal role in the regulation of inflammatory response during pathogenic
infections. The present study was conducted to investigate the chemo-suppressive and
cytokine-modulating effects of insulin administration in malaria-infected mice and the
involvement of GSK3β. Intraperitoneal administrations of 0.3 and 0.5 U/kg body weight
insulin each for four consecutive days into Plasmodium berghei NK65 (PbN)-infected mice
resulted in chemo-suppression exceeding 60% and improved median survival time of infected
mice (20.5 days and 19 days respectively compared to 15.5 days for non-treated control).
Western analysis revealed that pGSK3β (Ser9) intensity in brain samples from insulin-treated
(0.3 and 0.5 U/kg body weight) infected mice each were 0.6 and 2.2 times respectively than
that in control. In liver samples, pGSK3β (Ser9) intensity from insulin-treated infected mice
were significantly higher (4.8 and 16.1 fold for 0.3 and 0.5 U/kg bw respectively) than that in
control. Insulin administration decreased both brain and liver pNF-κB p65 (Ser536) intensities
(to 0.8 and 0.6 times for 0.3 U/kg bw insulin; and to 0.2 and 0.1 times for 0.5 U/kg bw insulin
respectively compared to control). Insulin treatment (0.5 U/kg bw) also significantly decreased
the serum levels of pro-inflammatory cytokines (TNF-α (3.3 times) and IFN-γ (4.9 times))
whilst significantly increasing the levels of anti-inflammatory cytokines (IL-4 (4.9 fold) and
IL-10 (2.1 fold)) in PbN-infected mice. Results from this study demonstrated that the cytokinemodulating effects of insulin at least in part involve inhibition of GSK3β and consequent
inhibition of the activation of NF-κB p65 suggesting insulin as a potential adjunctive therapeutic
for malaria.
