Leprosy is a chronic infection in humans that mainly affects the peripheral nerves and skin. Paraffin filling has been previously used for muscle atrophy treatment. However, the formation of paraffin granulomas (paraffinomas) can occur over the long term. We encountered a patient with leprosy who had hypothenar muscle atrophy caused by ulnar neuropathy. The patient was treated with paraffin injection at the hypothenar site for cosmetic appearance 60 years ago. Consequently, the paraffin formed a paraffinoma and a recurrent infected skin ulcer. Thus, paraffinoma removal and transfer of ulnar artery perforator adiposal flap (140 × 20 mm) were performed. The ulnar artery perforator adiposal flap was used for infection control and filling the dead space after paraffin removal. The skin healed without complications. Ultrasound confirmed residual adipose tissue and blood flow at the last follow-up.Mycobacterium heraklionense is a rare etiology of serious hand infection with only 2 cases having been reported in literature to date to our knowledge. We describe the case of a 58-year-old woman with persistent swelling and stiffness in her right index finger. Advanced imaging studies in addition to serial surgical debridement with tissue cultures helped to confirm the diagnosis of flexor tenosynovitis caused by M. heraklionense. In this case report, we highlight the clinical evaluation, operative treatment, and antimicrobial therapy leading to the successful care of this disease presentation. Due to its rarity and potential to cause substantial hand infection, M. heraklionense should be included in the differential diagnosis as the cause for chronic flexor tenosynovitis to appropriately minimize morbidity.
Periprosthetic tibial fractures in Total Knee Arthroplasty are much less commonly seen than femoral fractures, and there is a paucity of available literature and management recommendation for these fractures. We aimed to identify the relevant and up-to-date literature on this subject to analyse the incidence, risk factors, and management recommendations.

A literature search was done on the databases of PubMed and SCOPUS using appropriate keywords. All the published literature in the English language was included for this review.

We included 21 studies comprising 260 tibial periprosthetic fractures (91 intra-operative (35%) and 169 (65%) post-operative or delayed fractures). Only 5.9% of these fractures were managed conservatively. Whereas 98 cases (58%) were managed with open reduction and internal fixation (ORIF) with plating, 19 (11.2%) were managed with revision TKA. Seventeen cases (10%) were managed with minimally invasive percutaneous plate osteosynthesis (MIPPO), and 8 (4.7%) were managed with intramedullary nailing. Less than 6% of cases were managed with other means, viz. megaprosthesis (n=4), arthrodesis (n=5), amputation (n=1), and external fixator (n=1).

Intraoperative fractures accounted for one-third of the fractures in our review. A majority of the delayed periprosthetic fractures were treated with surgical intervention. The most preferred surgical treatment method was ORIF of fractures using locking plates (either open or MIPPO). Revision TKA or megaprosthesis was used in cases with the loosened implants in association with the fracture.

Open surgical curettage is associated with high risk of recurrence and potential for damage to the physis resulting in growth disturbances. We report a 14-year-old girl with chondroblastoma involving the distal femoral epiphysis in whom an arthroscopic approach was employed for thorough curettage of the lesion under direct vision followed by cavity management using bone graft substitute. At seven years follow-up she is asymptomatic, has normal knee function and her radiographs have shown good osteointegration of the synthetic graft with no evidence of recurrence. By combining the principles of intra-articular and endosteal arthroscopy in select patients, both tumour excision and cavity management can be done arthroscopically.
The presence of geographic and demographic disparities in randomized controlled trials (RCTs) may affect the external validity of trials. While some studies have addressed racial or ethnic disparities, they have been limited to a certain region, and there is limited information about the global representation in orthopaedic research.

RCTs published in major medical and orthopaedic journals from 2010 to 2019 were identified. After screening 6961 articles, 1769 trials enrolling 323,506 patients were included. The details of individual trials such as the country of origin, the proportion of women, and the proportion of different racial groups were recorded. Factors associated with reporting and representation of specific demographic groups, and annual changes were assessed.

Majority of the trials were from were from United States (US) (N=380, 21.5%). US (30.7%, N=99,356), United Kingdom (15.7%, N=50,691) and Canada (8.3%, N=26,890) accounted for majority of the enrolled patients. selleck chemical 59.1% of the patients were women. Among US trials reporting race, 81.2% were White, and 9.9% were African American. There was no significant variation in the global distribution (p=0.056), percentage of women (p=0.811), or percentage of Whites (p=0.389) over the years.

The top three countries contributed to about 55% of the enrolled patients, whereas they contributed to only 6% of the world population. Overall, women appeared to be adequately represented in the trials, while racial minorities were underrepresented. There has not been any considerable improvement in the representation of developing regions or minorities over the last decade.

Traditionally, an unstable knee has been considered a contraindication for osteotomy. But with a better understanding of biomechanics of osteotomies and their effect on ligament instabilities, the beneficial role of osteotomies in managing an unstable knee is becoming clearer. This review looks at recent literature on this subject to help in formulating a management plan especially in failed ligament reconstruction patients.
Ornithine transcarbamylase deficiency (OTCD) is a rare disorder of the urea cycle that obstetricians should be aware of in order to guide management for pregnant carriers of the X-linked gene that causes the condition.

We present the pregnancy management and outcomes of two women with OTCD. The particular manifestations of the disease drive antenatal, intrapartum and postpartum management.

Preconception counseling, early prenatal diagnostics and multidisciplinary intrapartum and postpartum management plans contribute to improved outcomes for patients.

Challenges in diagnosis often lead to delays in initiation of treatment, which significantly increases complications, including caecal ischaemia, perforation, sepsis and death. This case report describes the development of Ogilvie's syndrome within 24 h of an emergency caesarean section which was promptly recognised and confirmed by computed tomography, which demonstrated caecal dilatation of 9.7 cm without evidence of mechanical obstruction. An elevated level of C-reactive protein of 320 mg/L raised early clinical suspicion of caecal ischaemia, and this was managed endoscopically. Fortunately, the patient did not have any significant complications despite the high morbidity and mortality rate associated with Ogilvie's syndrome, highlighting the importance of clinician awareness and early initiation of management.
High infection rates after cesarean section are a major concern in the United States. A majority of antiseptics have irritant properties if they are not used as specified in companies' guidelines. Allergic contact dermatitis caused by povidone‑iodine is infrequent and is misdiagnosed by clinicians who fail to differentiate allergy from irritation. This case report describes an allergic reaction to povidone‑iodine after cesarean section.

A 28-year-old underwent a repeat low transverse cesarean-section at 39weeks of gestation. The patient informed the medical team that she had no known allergies and no significant past medical history. The new hospital protocol included cleaning the skin over the planned incision site multiple times with povidone‑iodine 7.5% scrub followed by povidone‑iodine 10% paint. The surrounding skin was prepped with chlorhexidine. The patient complained of an allergic reaction on her skin the night after the procedure, with severe itching, and stated that it got progressively worse. The patient was started on an oral regimen of steroids and hydroxyzine. The itching slowly improved and at discharge the patient was continued on hydroxyzine and steroids were discontinued. By the patient's six-week postpartum visit, skin hypopigmentation had completely resolved.

This case illustrates a reaction to povidone‑iodine after cesarean section. This allergic reaction could not be attributed to any other portions of the procedure.

We used a chemical box-model to show that production of nighttime oxidant, NO3, was affected mainly by emission decrease (average nighttime production rates 1.2, 0.8 and 1.5 ppbv hr-1 before, during and relaxation of lockdown restrictions, respectively), while NO3 sinks were sensitive to both emission reduction and seasonal variations. We have also shown that the maximum potential mixing ratio of nitryl chloride, a photolytic chlorine radical source which has not been previously considered in the IGP, is as high as 5.5 ppbv at this inland site, resulting from strong nitrate radical production and a potentially large particulate chloride mass. This analysis suggests that air quality measurement campaigns and modeling explicitly consider heterogeneous nitrogen oxide and halogen chemistry.The COVID-19 pandemic has been a life-altering shock to society. However, there have been serendipitous outcomes from the associated lockdowns ranging from improved air quality to reductions in carbon emissions. Liu et al. (2022, https//doi.org/10.1029/2021GL096842) revealed that even the magnitude of the heat islands in Chinese cities were reduced due to a decline in human activities and their associated anthropogenic contributions. These surprising findings have significant implications for understanding intersections among climate, health, energy, urban planning, transportation, and infrastructure.
