Intravitreal Corticosteroid Implantation in Diabetic Macular Edema: Updated European Consensus Guidance on Monitoring and Managing Intraocular Pressure.

Intravitreal therapy for diabetic macular edema can, in susceptible patients, increase intraocular pressure (IOP). As uncontrolled IOP can potentially be sight threatening, monitoring is an essential component of patient management. It can be challenging for retina specialists to ensure that monitoring is rigorous enough to detect and resolve any potential problems at the earliest opportunity without it also being overburdensome for patients who have the lowest risk of developing an IOP rise. We have developed dynamic algorithms that: (1) tailor the frequency and extent of monitoring according to individual susceptibility and current IOP and (2) assist retina specialists in deciding when they should consider a referral to a glaucoma specialist. One algorithm is for patients with a relatively low susceptibility to developing an IOP rise (those whose baseline IOP is < 22 mmHg and who do not have a history of IOP events). Depending on their first post-implantation IOP check, the algorithm classifies them as: low risk if IOP remains < 22 mmHg; medium risk if IOP is 22-25 mmHg and any rise from baseline is < 10 mmHg; or high risk if IOP is > 25 mmHg or any rise from baseline is ≥ 10 mmHg. Thereafter, the algorithm guides on the frequency and extent of monitoring required in each of these groups and, if IOP rises or falls during treatment, patients may move up or down the risk groups accordingly. A different algorithm is provided for patients who are more susceptible to developing an IOP rise (those with a baseline IOP of ≥ 22 mmHg or a prior history of an IOP event). These patients need monitoring more closely so this algorithm has only medium- or high-risk classifications. These algorithms update the previous monitoring guidance by Goñi et al. (Goñi et al. in Ophthalmol Ther 5:47-61, 2016).

Some people with diabetes have macular edema, which is a swelling of the central part of the retina (the tissue that lines the back of the eye). This swelling can threaten eyesight if untreated.Injecting a drug such as a corticosteroid into the eye can help treat the condition. Sometimes this has a side effect of increasing intraocular pressure (pressure within the eye). A small or short-lived rise in eye pressure should be no cause for concern, but it is very important to ensure the pressure is not too high for too long­because this could lead to the loss of eyesight. To prevent this happening, an eye doctor needs to check the eye pressure regularly.Some people are more susceptible to this problem­for example, people who have had any problems related to eye pressure in the past or people whose eyes already have a higher than normal pressure even before treatment. People who are most susceptible may need more types of checks and more frequent checks to ensure that any problems are found and treated quickly.We have developed flowcharts that help eye doctors decide which checks are needed and how often based on what the doctor knows about the person's eye before treatment and what they see at each check-up after treatment. They help doctors make sure that everyone has check-ups at the right time and they help doctors spot any problems early so that they can be resolved before long-lasting damage can occur.

Do We Have to Treat All T3 Rectal Cancer the Same Way?

Chemoradiotherapy (CRT) followed by surgery is the recommended approach in the last years for stage II and III rectal cancer with the intention to decrease the risk of local recurrence. However, fewer patients benefit from this strategy in terms of overall survival and long-term adverse outcomes because T3 rectal cancer has a broad range of prognosis, as shown by recent publications. Many patients with cT3 rectal cancer have a substantial risk of overtreatment with long-term toxicity related to radiotherapy that could be avoided in a subset group of cT3 tumors with good prognosis. These findings raised the question of whether all cT3 rectal cancer should receive preoperative radiotherapy and if a selected cT3 subgroup could be treated by surgery alone. This review addresses the rationale of selecting good prognosis cT3 rectal cancer for surgery alone and analyzes the data to support this recommendation.

Primary mesenchymal chondrosarcoma of the kidney: A case report and review of literature.

Primary mesenchymal chondrosarcoma of the kidney is extremely rare, with only nine cases reported in the English literature. We report a new case of this disease. A 35-year-old man, presented with flank pain, episodic gross hematuria and a painless palpable mass in left abdominal quadrant. Computed tomography scan identified a left renal tumor with 20 cm, with no evidence of regional or metastatic spread disease. The patient underwent radical nephrectomy. The immunohistopathological diagnosis was mesenchymal chondrosarcoma of the kidney. At 18 months of follow-up, there was no evidence of recurrence or distant metastasis. Primary renal chondrosarcoma is so rare that its prognosis is unknown. Disease recurrence is unpredictable and when it is detected, the prognosis is poor. The radical nephrectomy with complete resection of the tumor with wide resection free margins is recommended, and the patients need long-term and close surveillance, with particular attention to local recurrence and uncommon sites of metastization.
