Risperidone Treatment

Neutropenia is an adverse effect of various pharmacological therapies, including antipsychotics. Among the second-generation antipsychotic (SGA) medications, clozapine is most notable for neutropenic adverse effect. Risperidone, another SGA drug, is linked mainly with metabolic adverse effects, but rarely, blood dyscrasia adverse reactions have been reported. Hence, we report the case of a 56-year-old African American woman who developed severe neutropenia following two weeks of oral risperidone treatment. Her neutrophil levels returned to normal limits following discontinuation of risperidone and switching to haloperidol.

OBJECTIVE: To report a case of a neurotoxic syndrome in a patient undergoing concomitant treatment with risperidone and fluvoxamine. CASE REPORT: A 24-year-old African American woman hospitalized for psychosis was unresponsive to risperidone. Because of obsessive symptoms, low doses of fluvoxamine were added to her treatment regimen. Within 2 days, she developed confusion, diaphoresis, diarrhea, hyperreflexia, and myoclonus, which then progressed to rigidity, fever, and unresponsiveness, requiring endotracheal intubation. Symptoms resolved over 10 days with discontinuation of medication, hydration, and bromocriptine 5 mg 3 × daily. Ultimately, she was treated with olanzapine and fluvoxamine without adverse effects. DISCUSSION: This represents the first reported case of a neurotoxic syndrome secondary to treatment with risperidone and fluvoxamine. Differential diagnosis between neuroleptic malignant syndrome (NMS) and serotonin syndrome (SS) could not be accurately determined because of the overlap of signs and symptoms of both syndromes. NMS and SS may represent different aspects of a more generalized neurotoxic syndrome. This could be an important consideration in formulating treatment for neurotoxic syndromes. CONCLUSIONS: Clinicians should be aware of potentially serious adverse reactions that may occur during concomitant treatment with antipsychotics and selective serotonin-reuptake inhibitors.

Abstract Background Neutropenia, a decrease in total number of neutrophils below 1500/mm3 and particularly severe neutropenia, defined as neutrophils less than 500/mm3, is a potential adverse effect of antipsychotic medications that can lead to increased risk of infections and death. However, much of the attention on the potential adverse effect is centered exclusively on clozapine, which remains the only antipsychotic medication in the United States requiring standardized monitoring of blood work. We demonstrate here that paliperidone can also cause neutropenia and therefore clinicians should be aware of this possibility especially during initiation of treatment. Case presentation The following report presents the case of a 23-year-old African American male with first episode psychosis who developed neutropenia after initiation of paliperidone. Neutropenia resolved after discontinuation of paliperidone and initiation of an alternative antipsychotic, haloperidol. Conclusions This case report demonstrates an example of paliperidone induced neutropenia which resolved with a switch to haloperidol. We conclude that when initiating paliperidone, clinicians should be more aware of the risk of neutropenia. Moreover, neutropenia may be a more common and overlooked issue in patients on antipsychotic medications other than clozapine and increased awareness of comparative risk across antipsychotics could help direct treatment.

Urinary Metanephrines

One pitfall in 24-hour urine collection is the input of incorrect urinary volume by the reference laboratory. This may lead to an incorrect diagnosis of pheochromocytoma or paraganglioma. A 48-year-old African-American woman was seen in the clinic for an elevated 24-hour urine metanephrine screen during workup for secondary hypertension. Urine volume was found to be incorrectly inputted by the lab as 9750 mL rather than 975 mL. The urinary metanephrines were then recalculated and the 24-hour urinary metanephrines resulted within normal limits. This case highlights this unique and potentially under-recognised error in testing with 24-hour urine volume collection.

Muscle Metastasis

Cervical cancer is the fourth most common cancer in women worldwide, with a large majority of prevalence (85%) in developing countries. As of 2012, it accounts for 7.5% of all female cancer deaths. Despite its high prevalence, skeletal muscle metastasis from cervical cancer is extremely uncommon. In our extensive literature search, we were able to find only 8 cases where skeletal muscle metastasis was the only site of recurrence. We report a case of a 52-year-old African-American woman with a past medical history of cervical cancer (stage IIIB) who presented with pain and swelling in her left upper arm over the preceding 2 months. MRI of the left upper arm showed a solid well-circumscribed mass measuring 7.0 × 2.8 × 2.5 cm, deep to the biceps. Biopsy of the mass revealed a metastatic squamous cell carcinoma that was p16-positive. PET scan showed that the lesion was the sole site of metastasis. She received local radiation with concurrent chemotherapy. Follow-up MRI 6 months after the completion of therapy showed resolution of the mass. She has remained disease-free for the last 24 months as evidenced by a PET/CT scan in May 2016. In this case report, we discuss the role of imaging and pathology in the diagnosis of a solitary metastatic lesion. This case also emphasizes the importance of a close follow-up which aids in early intervention, increasing overall survival.

Moyamoya is a rare idiopathic progressive vaso-occlusive disease characterized by irreversible condition of main blood vessels to the brain as they enter into the skull. We present a case of 36 year old African American female presenting to the Out Patient Clinic with headache which were on and off for 4-6 months and did not relieve on routine medical therapy. It was associated with weakness on right side for last few days. The patient was investigated with CT Angiogram, diagnosed as Moyamoya disease and operated. She has been followed up for the last 5 years and the patient has not complained of any headaches or focal neurological symptoms.
