ABSTRACT
Idiopathic normal pressure hydrocephalus (iNPH) is a disorder observed in elderly patients causing gait disturbance, urinary incontinence and cognitive impairment. Due to the rapidly aging society, the number of patients with iNPH continues to increase yearly. However, iNPH is often overlooked because of its insidious and variable presentation. In the primary care setting, iNPH can be coincidentally discovered by neuroimaging findings, including disproportionately enlarged subarachnoid space hydrocephalus (DESH). We report two cases of iNPH in the elderly living alone that had different outcomes depending upon the availability of neurosurgery specialists. It is essential for primary care physicians to consult neurosurgeons without delay because prompt diagnosis and treatment can improve the patient's quality of life and prolong their duration of living at home.
ABSTRACT
ABSTRACT: A case of infectious mononucleosis (IM) in a previously healthy 43-year-old male is presented. The patient complained of fever and a sore throat of 3 weeks' duration. Although blood tests showed a marked increase in atypical lymphocytes, tests for Epstein-Barr virus (EBV) and cytomegalovirus (CMV) were negative. Human immunodeficiency virus type 1 (HIV-1) antibody was positive on enzymelinked immunosorbent assay (ELISA), and the HIV-1 viral load was 6.4×10<SUP>4</SUP>copies/mL. Western blot (WB) analysis did not initially confirm HIV-1 infection ; however, HIV-1 infection was confirmed one month after presentation. Although several pathogens can cause infections presenting as IM, in Japan there have been few reports of acute retroviral syndrome presenting as IM. This case is being reported to stress the importance of the early diagnosis of acute retroviral syndrome.
ABSTRACT
We report the case of a 59-year-old man who presented with classical-type fever of unknown origin (FUO) during observation of hypertension and polycystic kidney. The presence of malignancy was suspected based on elevation of tumor marker levels. We examined the patient carefully and attempted diagnostic imaging, but definitive diagnosis was difficult due to the presence of multiple hepatic cysts. Hepatic biopsy detected adenocarcinoma, but identifying whether lesions were primary cholangiocellular carcinoma or metastases was difficult, and we were ultimately unable to diagnose the tumors as cholangiocellular carcinoma until autopsy. Polycystic kidney with hepatic cysts and complicated by cholangiocellular carcinoma is rare, but should be considered among the differential diagnosis for FUO, which itself is frequently encountered.
