OBJECTIVE: The present report describes a case of choreoathetotic movements which were most probably induced by sildenafil in a patient with Parkinson's disease (PD) treated with levodopa/carbidopa (LD/CD). CASE SUMMARY: A 56-year-old retired man was admitted to hospital because of bizarre, involuntary movements and a…

Like other members of the signal transducer and activator of transcription (STAT) family of proteins, STAT6 has a dual role as signaling molecule and transcription factor. STAT6 is tightly connected to IL-4 and IL-13 signaling, and plays a key role in TH2 polarization of the immune system, as studies on knockout mice h…

Arcobacter species are Gram-negative spiral-shaped organisms belonging to the family Campylobacteraceae that can grow microaerobically or aerobically. The Arcobacter organisms also have the ability to grow at 15 degrees C, which is a distinctive feature that differentiates Arcobacter species from Campylobacter species.…

PURPOSE: This article gives an overview of the possibilities of conventional radiography in the diagnosis of inflammatory bowel disease of the small intestine and colon. MATERIAL AND METHODS: For more than 25 years we examine the small bowel employing enteroclysis with barium and methylcellulose and the colon with the…

BACKGROUND: The increase in HIV infections in South Africa is alarming. The aim of this prospective 4-year study was to evaluate the rising incidence of HIV-related admissions due to meningitis at the Pretoria Academic Hospital (PAH) adult neurology ward and to investigate the spectrum of meningitis during this time.…

OBJECTIVE: The authors introduce a simple six-step infiltration technique that results in satisfactory local anesthesia and prolonged postoperative analgesia, requiring a maximum of 30 to 40 mL of local anesthetic solution. SUMMARY BACKGROUND DATA: For the last 20 years, more than 12,000 groin hernia repairs have been…

One hundred and thirty-nine untreated patients with acute myelogenous leukaemia (AML) were admitted between August 1970 and December 1973 and allocated into two remission treatment regimens: one to receive chemotherapy alone and the other chemotherapy with immunotherapy. Of the patients who attained remission. 22 were…

BACKGROUND: The anisometropic eye of patients with bilateral hyperopic refractive amblyopia is presumed to have worse prognosis for visual acuity than the fellow eye. We sought to investigate the effect of anisometropia on visual prognosis in patients with bilateral hyperopic refractive amblyopia in order to estimate t…

Disproportionate rates of sexually transmitted diseases (STDs), including HIV, and unintended pregnancy among adolescents persist and might have been affected by the COVID-19 pandemic. This study uses 2019 and 2021 data from the nationally representative Youth Risk Behavior Surveys to characterize changes in sexual beh…

South Africa's HIV prevalence among young people remains among the highest in the world. A cross-sectional study was carried out in 2012 to estimate prevalences of sexual risk behavior and hazardous alcohol use (HAU) (via the Alcohol Use Disorder Identification Test) as well as to investigate potential associations bet…

The role of gene flow in species formation is a major unresolved issue in speciation biology. Progress in this area requires information on the long-term patterns of gene flow between diverging species. Here, we used thousands of single-nucleotide polymorphisms derived from transcriptome resequencing and a method model…

A 12 year old female with three to four annual episodes of respiratory tract infections since age 2 months, was admitted to the hospital with the chief complaint of acute bronchitis. During her hospital stay, the diagnosis of left pulmonary hypoplasia was considered, which was lately confirmed by means of respiratory f…

Between 1936 and 1987, 82 patients with adrenal cortical carcinoma were seen at our clinic. Of these patients 49 (72 per cent) have been seen during the last 25 years. A total of 40 patients (48.8 per cent) presented with a hormonally functional tumor and 42 (51.2 per cent) had a nonfunctional tumor. Forty patients (48…

Synthetic polymer chemistry has undergone two major developments in the last two decades. About 20 years ago, reversible-deactivation radical polymerization processes started to give access to a wide range of polymeric architectures made from an almost infinite reservoir of functional building blocks. A few years later…

OBJECTIVE: To describe the demographic and clinical profiles of a cohort of environmentally representative severe traumatic brain injury (TBI) cases collected for the past 25 years and to analyse the changes that occurred by dividing the analysis period into 3 equal time periods. MATERIAL AND METHODS: This was an obse…

Late Pleistocene hippo fossils (Hippopotamus amphibius) from Europe have generally been associated with the last interglacial period (Eemian, 129-115 thousand years ago [kya]).As a widely accepted indicator species for temperate climate conditions, it was assumed they went extinct with the onset of the last glacial (We…

Patients with advanced unresectable hilar cholangiocarcinoma have poor prognosis, and the survival is usually short. Herein, we report a 9-year survival case of unresectable hilar cholangiocarcinoma treated with chemoradiotherapy. A 64-year-old male patient presented with hilar cholangiocarcinoma. The tumor was located…

Background/aim: Tuberculous peritonitis may be difficult to diagnose due to its insidious and variable clinical manifestations as well as characteristics similar to malignancy. In this study, case reports from Turkey over the last 10 years were reviewed systematically using pooled analysis. Materials and methods: Thirt…

We analysed the number of pulmonary embolism (PE) in young females aged 10-39 years in the period from 2005 to 2014 in Germany to see any trends that possibly may reflect some influences of newer oral contraceptives. Detailed lists of all hospitalized cases with the principal diagnosis PE coded as I26 in the years 2005…

Kaposi's sarcoma (KS) is a leading cause of morbidity among 25-30% of AIDS patients and is by far the most common AIDS-associated malignancy. Since the beginning of the 1990s the incidence of KS continuously declined, but it was the introduction of protease inhibitors that markedly reinforced this phenomenon. In our ex…
