Tumoral calcinosis (TC) has long been a controversial clinico-pathological entity. Its pathogenesis and genetic background have been gradually unravelled since its first description in 1943. According to the presence or absence of an underlying calcifying disease process, TC has been divided into primary and secondary varieties. Two subtypes of the primary variety exist; a hyper-phosphatemic type with familial basis represented by mutations in GalNAc transferase 3 gene (GALNT3), KLOTHO or Fibroblast growth factor 23 (FGF23) genes, and a normo-phosphatemic type with growing evidence of underlying familial base represented by mutation in SAMD9 gene. The secondary variety is mainly associated with chronic renal failure and the resulting secondary or tertiary hyperparathyroidism. Diagnosis of TC relies on typical radiographic features (on plain radiographs and computed tomography) and the biochemical profile. Magnetic resonance imaging can be done in difficult cases, and scintigraphy reflects the disease activity. Treatment is mainly surgical for the primary variety; however, a stage-oriented conservative approach using phosphate binders, phosphate restricted diets and acetazolamide should be considered before the surgical approach is pursued due to the high rate of recurrences and complications after surgical intervention. Medical treatment is the mainstay for treatment of the secondary variety, with failure warranting subtotal or total parathyroidectomy. Surgical intervention in these patients should be kept as a last resort.
This study showed that active PTH production coincides with regeneration of parathyroid cells and that autotransplantation of at least two resected or devascularized glands during total thyroidectomy nearly eliminates permanent postoperative hypoparathyroidism, thus improving the safety of total thyroidectomy performed for malignant or benign disease.
ObjectiveWe compared the cost-effectiveness of two inpatient diabetes care models: one offered by a specialized diabetes team (SDT) versus a primary service team (PST).Research design and methodsWe retrospectively evaluated 756 hospital admissions of patients with diabetes to non-critical care units over 6 months. Out of 392 patients who met the eligibility criteria, 262 were matched 1:1 based on the mean of the initial four blood glucose (BG) values after admission. Primary outcomes were 30-day readmission rate and frequency, hospital length of stay (LOS) and estimated hospital cost. Secondary outcomes included glycemic control and BG variability.ResultsDiabetes complexity and in-hospital complications were significantly higher among patients treated by SDT versus PST. Thirty-day readmission rate to medical services was lower by 30.5% in the SDT group versus the PST group (P<0.001), while 30-day readmission rate to surgical services was 5% higher in the SDT group versus the PST group (P<0.05), but frequency of 30-day readmissions was lower (1.1 vs 1.6 times, P<0.05). LOS in medical services was not different between the two groups, but it was significantly longer in surgical services in SDT (P<0.05). However, LOS was significantly lower in patients who were seen by SDT during the first 24 hours of admission compared with those who were seen after that (4.7 vs 6.1 days, P<0.001). Compliance to follow-up was higher in the SDT group. These changes were translated into considerable cost saving.ConclusionsInpatient diabetes management by an SDT significantly reduces 30-day readmission rate to medical services, reduces inpatient diabetes cost, and improves transition of care and adherence to follow-up. SDT consultation during the first 24 hours of admission was associated with a significantly shorter hospital LOS.
These findings show that (a) the Karydakis procedure for managing chronic pilonidal sinus in obese patients is easy to perform, has a fast healing time, short hospital stay, rapid return to work, and a low recurrence rate, (b) the results are similar between nonobese and obese patients, with no recurrence seen in these patients, and (c) complications occur in patients with a BMI greater than 30; in such patients a dietary regimen before operation is advisable, and inserting a suction drain during operation is recommended to avoid seroma formation.
LigaSure hemorrhoidectomy and stapled hemorrhoidopexy yield comparable good results, with a short operative time and minimal side effects in the treatment of grade III and IV hemorrhoids, but with a lower rate of residual prolapse for the LigaSure procedure. Both procedures offer low levels of postoperative pain and therefore are excellent therapeutic options for prolapsed grade III and IV hemorrhoids. A larger controlled study is needed to reach solid conclusions regarding risk of postoperative recurrence of hemorrhoidal prolapse.
Partial or complete remission from type 2 diabetes was recently observed after bariatric surgeries. Limited data is available about the possibility of inducing diabetes remission through intensive weight reduction. We retrospectively evaluated diabetes remissions after one year of the Weight Achievement and Intensive Treatment (Why WAIT) program, a 12-week intensive program for diabetes weight management in real-world clinical practice. Among 120 obese patients with type 2 diabetes who completed the program, 88 patients returned for follow-up at one year. Nineteen patients (21.6%) had major improvement in their glycemic control, defined as achieving an A1C <6.5% after one year. Four patients (4.5%) achieved either partial or complete diabetes remission defined as A1C <6.5% and <5.7%, respectively, on no antihyperglycemic medications for one year; 2 achieved partial remission (2.3%) and 2 achieved complete remission (2.3%). At the time of intervention, patients who achieved diabetes remission had shorter diabetes duration (<5 years) and lower A1C (<8%) and were treated with fewer than 2 oral medications. They achieved a weight reduction of >7% after 12 weeks. These results indicate that a subset of obese patients with type 2 diabetes is appropriate for intensive lifestyle intervention with the aim of inducing diabetes remission.
The effect of pretreatment with FK506 on renal ischemia and reperfusion (I/R) injury was investigated using a rat model. Animals were assigned to one of two groups (20 rats each). Group 1 animals (controls) received 0.5 ml saline while group 2 animals received FK506 (0.3 mg/kg), administered intravenously 24 hr prior to the induction of renal ischemia. A 60-min period of ischemia of the right kidney was induced, and upon reperfusion a left nephrectomy was performed. Blood samples for estimation of BUN, creatinine, and tumor necrosis factor were collected on days 0 (preischemia), 1, 2, 3, 5, 7, and 10 (postischemia). Rats were sacrificed after day 10 and renal tissue was examined histologically. All animals survived the ischemic episode. FK506 pretreatment significantly reduced the serum levels of BUN (P less than 0.02), creatinine (P less than 0.02), and TNF (P less than 0.05) as compared with that seen in controls. Histologically, at day 10, the kidneys showed the expected sequelae of prior renal I/R with various degrees of tubular damage. However, no objective differences were evident between the two groups. Based upon these data, it can be concluded that (1) FK506 pretreatment ameliorates the functional renal injury associated with I/R, (2) renal ischemia induces the release of TNF, and (3) FK506 pretreatment results in a significant inhibition of TNF production. These data suggest that the release of TNF may be responsible for the increasing of BUN and creatinine levels seen after renal I/R and that pretreatment of renal donors with FK506 may improve renal function in the immediate post-transplant period.
LH is a better alternative than conventional OH in treating prolapsed hemorrhoids (grades III and IV) since it reduces operating time, postoperative pain, and time off work, and allows surgical wounds to heal faster, with minimal comparable side effects and a low recurrence rate.
