Recurrent Osteomyelitis Requiring Surgical Management Secondary to Nail-Biting: A Case Report.

CASE: Onychophagia, or nail-biting, is a common habit seen in both children and adults. Harmful effects include oral exposure to a variety of pathogens and concomitant damage to dentition and fingers. This report focuses on the most severe reported case of recurrent osteomyelitis of the bilateral hands with destructive changes secondary to onychophagia. CONCLUSION: Successful treatment relies on a multidisciplinary approach which in this case included surgical management and counseling on cessation, with referrals to other providers to address underlying psychiatric and/or psychologic conditions that may predispose to this compulsion.

Meniscus Repair Techniques.

The menisci play a vital role in maintaining knee function and protecting the chondral surfaces. Acute and chronic tears are common injuries among both young athletes and older patients with early degenerative changes. The progression of physiological derangement and chondral injury after meniscus injury and meniscectomy have prompted interest in expanding meniscus repair techniques. Recent literature encourages an attempt at repair in tear patterns previously declared irreparable if the tissue quality allows. The orthopedic surgeon should understand the multitude of techniques available to them and be prepared to combine techniques to optimize the quality of their repair construct. While biological augmentation may show some promising early results, the quality of the current data precludes strong recommendations in their favor.

Treatment of a Subacute Locked Thumb Metacarpophalangeal Joint with Sesamoid Entrapment.

INTRODUCTION: Locked thumb metacarpophalangeal (MCP) joints due to entrapped radial sesamoids are rare injuries that commonly require open reduction, especially when the injury is delayed in presentation. CASE PRESENTATION: We present a case of a 24-year-old female with a subacute thumb MCP joint subluxation due to an incarcerated radial sesamoid. She underwent successful closed reduction but had persistent pain and difficulty gripping large objects necessitating eventual open volar plate repair despite therapy. She was able to achieve full motion, with little pain and disability, after undergoing delayed volar plate repair. DISCUSSION: Delayed volar plate repair may be considered for those patients who fail to improve with conservative management and occupational therapy after a successful closed reduction for thumb MCP joint subluxation due to an incarcerated radial sesamoid.

Patient Safety: Driving After Foot and Ankle Surgery.

This article provides a review of the existing literature regarding driving limitations following lower extremity orthopedic surgery. Medicolegal requirements and insurance recommendations are often vague and subject to interpretation. Several studies have examined the impact of surgery and immobilization on brake reaction time. This study summarizes the findings of these studies. Additionally, the authors consider the impact of lower extremity amputations and peripheral vascular disease on driving. Literature regarding opioid use, obesity, sleep apnea, increasing age, and distraction is also reviewed. An improved understanding of these topics will enhance the orthopedic surgeon's ability to counsel patients and optimize their safety.

When a Child Dies Unexpectedly: No Truth Be Told.

Sudden death of a child beyond infancy is a rare event. We report a child who presented to the emergency care system with asystole and the caregiver's report of an asthma attack as the preceding event. After unsuccessful attempts at resuscitation, an autopsy was performed by the medical examiner. Despite only scattered bruises with no clear-cut signs of abuse, aortic rupture and spinal fractures were found. This case highlights the crucial role of the medical examiner in evaluating sudden childhood death, even in the setting of underlying illness.

Key diagnostic features of granulomatous interstitial nephritis due to Encephalitozoon cuniculi in a lung transplant recipient.

Microsporidia are increasingly recognized as opportunistic pathogens in immunocompromised organ transplant recipients (OTR). Disseminated infection due to Encephalitozoon sp. is reported mainly in human immunodeficiency virus (HIV)-positive patients and rarely in HIV-negative OTR. The clinical spectrum ranges from keratoconjunctivitis, to pneumonitis, to acute kidney injury. The kidney is a common site for disseminated infection; however, specialized techniques are required for definitive diagnosis. We report the first case of disseminated Encephalitozoon cuniculi infection in an HIV-negative lung transplant recipient diagnosed on renal biopsy. Five months after transplant, he presented with fever and a lung infiltrate and developed acute kidney injury. Renal biopsy showed granulomatous interstitial nephritis with gram-positive rod-shaped organisms with a "belt-like stripe" in tubular epithelial cells. Electron microscopy, polymerase chain reaction, and mammalian cell cultures of the urine sediment confirmed E. cuniculi infection. Retrospective review of a previous lung biopsy showed similar organisms. On the basis of electron microscopy findings, the patient was treated with albendazole, and immunosuppressive therapy was reduced. However, the patient expired due to Aspergillus pneumonia and disseminated E. cuniculi infection. Microsporidia should be considered in cases of fever of unknown origin and/or multiorgan infection in HIV-negative OTR when other causes have been excluded, as successful treatment requires early detection.
