Treatment of hypertension is a growing burden on urban health services in Zimbabwe. In 1980, the Harare Health Department began a separate registry, staffed by a nurse, for management of patients with stable hypertension (diastolic blood pressure (DBP less than 100 mmHg) on treatment). We evaluated this programme in a retrospective review of 437 medical records. The average age of patients was 17.5 years; two-thirds were women. Upon referral 324 patients (74 percent) had a DBP less than mmHg. Sixty-five percent of patients had no DBP greater than 100 mmHg during follow-up. Patients with DBP greater than 20 mmHg were more likely to be treated with two drugs, seen more often or referred (p less than 05). One-third of patients enrolled between 1980-1986 were lost to follow-up. Of those who did not default, few attended regularly. We conclude that a nurse can successfully manage patients with stable hypertension, although more aggressive treatment and improved compliance would have resulted in better control. At current levels of loss to follow-up, this programme is unlikely to have much effect on the public health impact of hypertension. The main challenge is to improve patient compliance.

Systemic capillary leak syndrome (SCLS) is a rare and life-threatening disorder characterized by acute hypotension, hypoalbuminemia, and hemoconcentration, which often results in severe respiratory complications, such as pulmonary edema. SCLS can be triggered by infections, including COVID-19, and is associated with a high mortality rate. Here, we report a case of COVID-19-associated SCLS in a 68-year-old man.

Spinal cord injuries, including rare cases without radiological abnormalities, pose diagnostic challenges, particularly in cases of delayed neurological deficit development. This case report describes a 55-year-old man with a stable L1 burst fracture who developed delayed neurological deficits two weeks after sustaining a fall despite no evidence of intrinsic or extrinsic spinal cord abnormalities on magnetic resonance imaging (MRI). The patient initially presented with back pain, normal muscle strength across all myotomes, and imaging that showed no canal stenosis or retropulsion fragments.

This video explores the technique of robot-assisted pyeloplasty using the Da-Vinci Single-Port robot through the supine anterior retroperitoneal access in a 28-year-old male with a right-sided ureteropelvic junction obstruction. The patient was placed in a supine position, with a 10°-20° elevation of the ipsilateral flank. Retroperitoneal access was obtained at the McBurney's point for the placement of the port.

Background: Health care providers often struggle to treat patients with chronic pain. One potential solution is to facilitate access to programs and tools that develop patients' skills and confidence in managing their own care.
Aims: This study aimed to describe the uptake of the Chronic Pain Self-Management Program (CPSMP) in Eastern Ontario and evaluate the effectiveness of the program in the acquisition of knowledge, confidence, and skills required to manage chronic pain, as measured by the Patient Activation Measure (PAM).

Background: Few studies have explored the link between nutritional status and prognosis in patients with epithelial ovarian cancer (EOC), and existing findings are controversial. Thus, this study aimed to explore the effects of pre-treatment nutrition-related indicators on the prognosis of patients with newly diagnosed EOC.
Methods: In this ambispective cohort study, 1,020 patients with EOC diagnosed by pathology examination were enrolled and followed-up until December 31, 2023.
