Morton's neuroma (MN) is a painful, proliferative fibrosis of perineural tissue caused by pressure or recurrent irritation that was previously thought to affect only the common interdigital nerve of the foot. We present a case of a bilateral MN of both the ulnar and radial proper digital nerves of the fifth finger in a 30-year-old patient, following multiple surgeries on the aforementioned finger. The patient was referred to our center by a peripheral hospital after traumatic fingertip amputation distal the DIP joint, where the fingertip was initially simply sutured. Because of progressive neuropathic pain, he underwent two revision surgeries, in which the distal phalanx was removed, two neuromas were excised, and the nerve stumps were shortened, but both were unsuccessful. A final, more extensive revision surgery was then carried out, in which two club-like enlargements were excised and the nerve stumps coadapted to form a loop. Histopathological examination of the excised specimen revealed perineural fibrosis in the context of a Morton's neuroma. This is, to our knowledge, the first documented case of a bilateral MN of the hand, which may have resulted from an inadequate primary finger and nerve shortening, resulting in high pressure from the surrounding soft tissue. Finally, this report emphasizes the significance of optimal treatment for finger amputation injuries, as well as the fact that for neuromas, simple nerve resection should be avoided whenever possible, because of the high recurrence rates.

Articular cartilage allows the human body to buffer and absorb stress during normal exercise. It is mainly composed of cartilage cells and the extracellular matrix and is surrounded by the extracellular microenvironment formed by synovial fluid and various factors in it. Studies have shown that chondrocytes are the metabolic center of articular cartilage. Under physiological conditions, the extracellular matrix is in a dynamic balance of anabolism and catabolism, and various factors and physical and chemical conditions in the extracellular microenvironment are also in a steady state. This homeostasis depends on the normal function of proteins represented by various ion channels on chondrocytes. In mammalian chondrocyte species, ion channels are mainly divided into two categories: cation channels and anion channels. Anion channels such as chloride channels have become hot research topics in recent years. These channels play an extremely important role in various physiological processes. Recently, a growing body of evidence has shown that many pathological processes, abnormal concentration of mechanical stress and chloride channel dysfunction in articular cartilage lead to microenvironment disorders, matrix and bone metabolism imbalances, which cause partial aseptic inflammation. These pathological processes initiate extracellular matrix degradation, abnormal chondrocyte death, hyperplasia of inflammatory synovium and bony. Osteoarthritis (OA) is a common clinical disease in orthopedics. Its typical manifestations are joint inflammation and pain caused by articular cartilage degeneration, but its pathogenesis has not been fully elucidated. Focusing on the physiological functions and pathological changes of chloride channels and pathophysiology of aseptic inflammation furthers the understanding of OA pathogenesis and provides possible targets for subsequent medication development.

To identify the neuroimaging predictors for the responsiveness of patients to sumatriptan and use an independent cohort for external validation.

Endometriosis is a condition associated with pelvic pain, infertility, and possibly with decreased quality of life as well as psychiatric disorder. The purpose of our study was to evaluate the association between pain characteristic, psychiatric disorder, and quality of life in women with endometriosis.

Dry needling is most commonly used in the subacute and chronic phases of an injury; therefore, it is imperative to understand the use of dry needling in the acute phases of an injury. There are four main reasons to use dry needling during the acute phase of injury: to relieve pain, decrease edema, increase range of motion and flexibility, and increase strength and power. Dry needling can be used pregame, postgame, during half time or an intermission, or following an injury. Although further research is needed, acute dry needling can be used to bolster athletes' health and possibly improve sports performance.

Regional anesthetic blockade of the adductor canal following anterior cruciate ligament reconstruction has gained popularity due to theoretical benefit of improved patient experience, decreased requirement for pain medication and maintained motor function. However, this block does not cover the anterior and lateral genicular innervation to the knee, which may lead to persistent pain postoperatively. The following Technical Note details the genicular nervous system and provides rationale and technique for performing a simple surgeon-administered regional anesthetic at the completion of anterior cruciate ligament reconstruction to address the anterior and lateral genicular nervous system.

Tarlov cysts (TCs) are dilated nerve root sheaths originating from increased cerebrospinal pressure. Patients with TCs often complain of neuropathic pain and paresthesia. The aim of this study was to retrospectively review intraepidermal nerve fiber density (IENFD) and electrodiagnostic (EDX) data from TC patients.

The impact of the coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome 2 (SARS-CoV-2) still continues. The duration of the immune response in individuals recovering from COVID-19 and its protection against future SARS-CoV-2 infection are not fully understood. This study aimed to longitudinally evaluate anti-SARS-CoV-2 seroconversion status in healthcare workers with positive SARS-CoV-2 Real-time reverse transcription polymerase chain reaction (rRT-PCR), test in Mersin University Hospital. A total of 68 healthcare workers with positive SARS-CoV-2 rRT-PCR test between 19 April and 27 November 2020 were included in the study. Blood samples were collected from healthcare workers for SARS-CoV-2 antibody testing in the 1st, 3rd and 5th months following PCR positivity. Healthcare workers were classified as symptomatic, asymptomatic and reinfected according to their clinical findings, and rRT-PCR cycle thresholds (Ct) were recorded. Elecsys Anti-SARS-CoV-2 (Roche Diagnostics, Germany) kit was used for antibody testing. Of the 68 healthcare workers; 46 were classified as symptomatic, 15 as asymptomatic, and seven as reinfected. Twenty-seven (39.7%) of the healthcare workers were male and 41 (60.3%) were female, and the mean age was 36.4 ± 9.04. Seroconversion was detected in 45 (66.2%) of 68 healthcare workers in the study, and only one person had sero-negative result at the end of the 5th month. While seroconversion was detected in 78.3% (n= 36/46) of symptomatic healthcare workers, it was observed in 26.7% (n= 4/15) of the asymptomatic healthcare workers. Seroconversion was detected in only one of the seven reinfected healthcare workers after primary infection. After reinfection, seroconversion was observed in five of seven reinfected healthcare workers. Antibody response was not detected in two of them after both infections. According to the rRT-PCR Ct values; the median of Ct value was found significantly lower in healthcare workers with seroconversion (23.26, IQR= 18.45-27.30), than the ones without seroconversion (36.20, IQR= 33.09-37.56) (p< 0.001). In those who had reinfection, the mean Ct value (31.77 ± 6.62) detected during the primary infection period was statistically higher than the Ct value (22.44 ± 5.54) detected during reinfection (p= 0.008). The most frequently recorded symptoms in healthcare workers were myalgia (57.3%), fatigue (51.5%), headache (51.5%) followed by sore throat (36.7%), fever (33.8%), cough (27.9%), diarrhea (23.5%) and dyspnea (16.2%). In addition, fever (52%) and fatigue (80.6%) were found to be significantly higher in seroconversion-positive healthcare workers than in those without seroconversion (p= 0.028; p= 0.005, respectively). As a result, a higher rate of antibody response was detected in healthcare workers who had symptomatic infection than those who were asymptomatic. It has been observed that patients with asymptomatic primary infection and without antibody response were more susceptible to reinfection. In addition, it was observed that the probability of immune response increased when the viral load increased (Ct value decreased) in symptomatic infections. Although these findings provide important information about the short-term seroconversion status of healthcare personnel; longer-term and larger-scale studies are needed to evaluate the long-term effectiveness of seroconversion and to better understand the effectiveness of the immune response developed after SARS-CoV-2 vaccine administrations.

is a well-known human-specific stomach pathogen that infects more than half of the world's population. The infection with this bacterium can cause a variety of gastrointestinal problems, including chronic gastritis, peptic ulcers, and even cancer. is a highly infectious bacterium. causes an increase in gastric mucosa pH or gastric mucosa intestinal metaplasia. These modifications in the stomach environment are necessary for colonization to occur. is a flagellate protozoan parasite that can cause giardiasis in humans and other mammals. It dwells in the duodenum and upper jejunum. Globally, over 280 million cases of human giardiasis are predicted to occur each year. Simultaneous human colonization by and is a typical occurrence since the viruses' predisposing factors are similar in both groups. Giardiasis is a parasitic infection that affects both children and adults worldwide. Infection with is more common in underdeveloped countries. Globally, more than 200 million cases of giardiasis are detected each year. In contrast, the presence of in the host body triggers an immunological response comparable to that of , with lymphocytes strongly polarized towards Th1. As a result, their combined presence exacerbates host tissue damage. The major goal of this seminar is to describe the pathophysiology, immunology, and clinical aspects of and coinfection using a comprehensive search of PubMed, Lancet, and Google Scholar sources. Upper gastrointestinal problems such as upper abdominal pain, abdominal bloating, nausea, vomiting, epigastric pain/burning, and belching are all caused by both organisms. Differentiation by physical examination is impossible in people infected with both bacteria. For this coinfection distinction, a laboratory diagnosis is required. and , when present together, have a synergistic effect on the host and can cause serious damage. As a result, researchers should delve deeper into the mechanics underlying this potential microbial interaction.
