Hydroxyurea (HU) is an antineoplastic drug commonly used to treat chronic myeloproliferative disorders. Common dermatological side effects include hyperpigmentation, scaling, erythema, alopecia, desquamation of face and hands. Leg ulceration following HU therapy is less common and very few cases have been reported so far. Objective of this paper is to increase the awareness of hydroxyurea induced leg ulcers which will aid in the early diagnosis and appropriate treatment. The first case was a chronic myeloid leukemia (CML) patient on HU 1.5 g/day for 5 yr, who had bilateral painful perimalleolar ulcers for 6 months. The second case was a CML patient on HU 1.5 g/day for 3 yr who developed bilateral lateral malleolar ulcers. Third case was a polycythemia vera (PV) patient on HU 1 g/day for 5 yr who presented with painful medial malleolar ulcer of 2 months. The last case of our report was an elderly PV patient on HU 1.5 g/day for 2 yr and presented with lateral malleolar ulcer which persisted on reducing the dose of HU. In all the 4 cases the ulcers healed on stopping HU. Our report confirms the association of chronic hydroxyurea therapy and perimalleolar ulcers which respond promptly after discontinuation of the drug. The heightened awareness among the physicians will promote early diagnosis and prompt relief from the agonizing ulcers.

A 21-kDa leptospiral lipoprotein (LipL21) was evaluated for its diagnostic potential to detect bovine leptospirosis by ELISA. Both native LipL21 (nLipL21) and recombinant LipL21 (rLipL21) proteins were tested and compared regarding diagnostic efficiency, and no statistically significant difference was observed. The sensitivity of rLipL21 ELISA for 62 microscopic agglutination test (MAT) positive sera was 100% and the specificity with 378 MAT negative sera was 97.09%. Thus, rLipL21 protein-based ELISA could be used as an alternative to MAT for the diagnosis of bovine leptospirosis.

Weight loss is an important goal in the management of several chronic conditions, including type 2 diabetes mellitus, and pharmacological therapies that aid weight loss are appealing. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT2is) are novel glucose-lowering therapies that have been shown to induce clinically significant reductions in body weight. However, this weight loss may not be attributed solely to fat mass (FM). Given the importance of skeletal muscle and lean body mass (LBM) on cardio-metabolic health and physical function, we reviewed the available literature reporting the effects of GLP-1RAs and SGLT2is on body composition. Results demonstrate that, in most circumstances, the weight loss associated with both therapies predominantly comprises a reduction in FM, although significant heterogeneity exists between studies. In over half of the studies identified, the proportion of LBM reduction ranged between 20% and 50% of total weight lost, which is consistent with diet-induced weight loss and bariatric surgery. No clear differences existed between GLP-1RAs and SGLT2is. Consequently, the loss of LBM and skeletal muscle associated with weight loss induced by GLP-1RAs and SGLT2is warrants attention. Strategies to preserve skeletal muscle and improve physical function, for example through structured exercise, are of great importance.

Methods: Twenty patients within 1 month of traumatic SCI who had been admitted to a tertiary care rehabilitation center were included in this study. Serum BTMs, C telopeptide (CTX) as a bone resorption marker, and osteocalcin as a bone formation marker, were serially measured at baseline, and 3 and 6 months after SCI. BTMs of SCI patients were compared with those of a control group of age-matched healthy males, premenopausal females, and a vulnerable group of postmenopausal females. Results: BTMs were significantly elevated in patients with SCI, with maximum levels observed at the 3rd month of injury. At baseline, the bone resorption marker CTX was approximately 3 times higher in SCI patients than in the control male population and premenopausal females, and about double that of postmenopausal females. The rise in the bone formation marker was marginal in comparison to that of the bone resorption marker. BTMs were persistently elevated and did not reach the normative range until the 6th month of SCI. Conclusions Raised bone resorption markers in comparison to bone formation markers indicate hyper-resorption-related bone loss following acute SCI. Markedly elevated bone resorption markers in the SCI population, compared with those in control and vulnerable groups, emphasize the need for early bone health monitoring and management.

Background/Aims: Chronic intestinal pseudo-obstruction (CIPO) is a rare cause of intestinal dysmotility. First-line treatment in adult patients is medical and nutritional therapy. For patients who fail these treatment options, surgical interventions may be an option. In this scoping review, we aim to investigate the current research on surgical interventions for CIPO in adults. Methods: PubMed, Embase, and Scopus were queried for articles related to surgical interventions for adults with CIPO. Search terms included:intestinal dysmotility, intestinal pseudo-obstruction, global intestinal dysmotility, chronic intestinal pseudo-obstruction, gastrointestinal paresis, neurogastrointestinal motility disorder, and chronic small intestinal motility disorder. Results: Initial search identified 4763 records; 4722 were deemed irrelevant after screening and were excluded. The remaining 41 reports were retrieved and assessed for eligibility. Twenty-one additional studies were excluded after in-depth assessment. The remaining 20 reportswere: 9 cohort studies, 7 case reports, and 4 reviews. Of these, 10 studies had study populations of < 10 patients, while 6 had ≥ 10patients. The remaining 4 were reviews. Results of these papers described the safety and effectiveness of various surgical interventions for adults with CIPO, including percutaneous endoscopic procedures, surgical decompression, small bowel resection, and intestinal transplantation. Conclusions Data pertaining to surgical therapy for CIPO is limited. Although this review suggests that surgical interventions for CIPO may be safe and effective for select patients, strong conclusions cannot be made due to limited number of relevant studies and small sample sizes.Concerted efforts to produce data from large studies on adults with CIPO are necessary.

Background: As the population is aging and indications are expanding, shoulder arthroplasty is becoming more frequent, especially bilateral staged replacement. However, surgeons are hesitant to use bilateral reverse prostheses due to potential limitations on activities of daily living. Methods: This meta-analysis was conducted to compare bilateral anatomic to bilateral reverse shoulder implants. PubMed, Cochrane, and Google Scholar (pages 1–20) were searched until April 2023. The clinical outcomes consisted of postoperative functional scores (American Shoulder and Elbow Surgeons [ASES], Single Assessment Numeric Evaluation [SANE], Physical Component Score [PCS], Mental Component Score, and Simple Shoulder Test), pain, and range of motion (external rotation and forward elevation). Three studies were included in this meta-analysis. Results: Bilateral anatomic implants had better postoperative functional outcomes and range of motion, but no significant difference was seen in postoperative pain when compared to the reverse prosthesis. Better ASES score, SANE score, and PCS as well as better external rotation and forward elevation were seen in the bilateral anatomic shoulder replacement group, but no significant difference in pain levels was seen between the two groups. Conclusions The results may be explained by the lower baseline seen in the reverse prosthesis group, which may be due to an older population and different indications. Nevertheless, more randomized controlled studies are needed to confirm these findings.Level of evidence: III.

Displaced olecranon fractures constitute a challenging problem for elbow surgeons. The purpose of this study is to evaluate the role of suture anchor fixation for treating patients with displaced olecranon fractures. Methods: A retrospective review was performed for all consecutive patients with displaced olecranon fractures treated with suture anchor fixation with at least 2 years of clinical follow-up. Surgical repair was performed acutely in all cases with nonmetallic suture anchors in a double-row configuration utilizing suture augmentation via the triceps tendon. Osseous union and perioperative complications were uniformly assessed. Results: Suture anchor fixation was performed on 17 patients with displaced olecranon fractures. Functional outcome scores were collected from 12 patients (70.6%). The mean age at the time of surgery was 65.6 years, and the mean follow-up was 5.6 years. Sixteen of 17 patients (94%) achieved osseous union in an acceptable position. No hardware-related complications or fixation failure occurred. Mean postoperative shortened disabilities of the arm, shoulder, and hand (QuickDASH) score was 3.8±6.9, and mean Oxford Elbow Score was 47.5±1.0, with nine patients (75%) achieving a perfect score. Conclusions: Suture anchor fixation of displaced olecranon fractures resulted in excellent midterm functional outcomes. Additionally, this technique resulted in high rates of osseous union without any hardware-related complications or fixation failures. Level of evidence: IV.
