Metacarpal Stress Fracture Is Not an Uncommon Condition in Adolescent Racket Athletes

Background. Stress fractures of the metacarpal bones are considered uncommon. We report on 11 adolescent athletes with these stress fractures, successfully treated with cessation of sports activities. Representative case presentation. In case 1, a 15-year-old male tennis player presented with right hand pain of 4-week duration without an acute trauma history. Tenderness existed on palpation along the dorsal and proximal second metacarpal bone. Plain radiographs demonstrated a periosteal reaction on the proximal shaft of the second metacarpal. Racket swinging was suspended. He returned to competitive tennis 2 months after the initial visit and continues to participate without symptoms. In case 2, a 16-year-old male boxer presented with right hand pain of 2-week duration that arose while punching. Acute trauma history was absent. Tenderness existed on palpation over the third metacarpal of the right hand. Plain radiographs demonstrated no periosteal reaction or fracture line. MRI showed a high signal on the third metatarsal bone on fat suppression and a low signal on T2-weighted images. Nonoperative treatment was initiated without external fixation, and punching was suspended. He returned to boxing 1 month after the initial visit without symptoms. Conclusions. The current case series of metacarpal stress fractures demonstrate that this condition is not as rare as previously reported. Metacarpal stress fractures are generally ignored since the clinical and radiological findings are mostly unclear. If an athlete experiences hand pain without acute onset during sports activities, especially in racket sports, the presence of a metacarpal stress fracture should be assessed by MRI.

A 55-year-old woman was referred because of diffuse pruritic erythematous lesions and an ischemic process of the third finger of her right hand. She was known to have anaemia secondary to hypermenorrhea. She presented six months before admission with a cutaneous infiltration on the left cubital cavity after a paravenous leakage of intravenous iron substitution. She then reported a progressive pruritic erythematous swelling of her left arm and lower extremities and trunk. Skin biopsy of a lesion on the right leg revealed a fibrillar, small-vessel vasculitis containing many eosinophils.Two months later she reported Raynaud symptoms in both hands, with a persistent violaceous coloration of the skin and cold sensation of her third digit of the right hand. A round 1.5 cm well-delimited swelling on the medial site of the left elbow was noted. The third digit of her right hand was cold and of violet colour. Eosinophilia (19 % of total leucocytes) was present. Doppler-duplex arterial examination of the upper extremities showed an occlusion of the cubital artery down to the palmar arcade on the right arm. Selective angiography of the right subclavian and brachial arteries showed diffuse alteration of the blood flow in the cubital artery and hand, with fine collateral circulation in the carpal region. Neither secondary causes of hypereosinophilia nor a myeloproliferative process was found. Considering the skin biopsy results and having excluded other causes of eosinophilia, we assumed the diagnosis of an eosinophilic vasculitis. Treatment with tacrolimus and high dose steroids was started, the latter tapered within 12 months and then stopped, but a dramatic flare-up of the vasculitis with Raynaud phenomenon occurred. A new immunosupressive approach with steroids and methotrexate was then introduced. This case of aggressive eosinophilic vasculitis is difficult to classify into the usual forms of vasculitis and constitutes a therapeutic challenge given the resistance to current immunosuppressive regimens.

Stress Fatigue

A prominent anterior bulge on a ceratopsian dinosaur phalanx was examined for evidence of infection or stress (fatigue) fracture. The presence of a knife-slice type radiolucency, associated with periosteal reaction, was pathognomonic (diagnostic) for a stress fracture. Stress fractures have previously been recognized only in humans, racing greyhounds, and horses.

Sports Activities

Smoking and alcohol consumption is a growing trend among young people worldwide. The purpose of this study was to provide students with a comparative analysis of adherence to harmful habits (smoking and alcohol) on the one hand and the frequency of sports and academic performance on the other, taking into account gender differences. The research was conducted in 2019-2020 in 5 cities of Russia; the sample included 1500 people aged 18.4 ± 1.1 years, divided into three equal groups. The control (first) group had students who are not engaged in sports, and the second group comprised students practicing sports but not professionally. The third group was made up of student-athletes. All participants were surveyed to determine the frequency of adherence to harmful habits. In the control group, boys smoked 50% more often than girls (p ≤ 0.05), while in the third group, smoking among boys was registered 70 times less often (p ≤ 0.001). Alcohol consumption in controls was 0.5 times more likely among boys (p ≤ 0.05). Harmful habits affect young people's free time and reduce their academic performance and ability to practice sports.

Bone Abnormalities

A patient with complaints of right foot pain and previous normal radiographs had an abnormal three-phase bone scan consistent with a second metatarsal stress fracture. Subsequent radiographs confirmed this diagnosis. Two months later, the patient developed pain in his left foot, and again initial radiographs were noncontributory. A later bone scan revealed a left second metatarsal stress fracture. The results in this case reemphasize the value of bone scintigraphy in patients with foot pain and no bone abnormalities on plain radiographs.

Valonia Ventricosa

The structure of the walls of vesicles of Valonia ventricosa and, to a less extent of other species, has been re-examined by the methods of X-ray analysis and electronmicroscopy, with particular reference to the criticism by Steward & Muhlethaler of the earlier statements of Preston & Astbury. It is shown that the cellulose microfibrils are present in three orientations, in separate lamellae. The third orientation, noted occasionally by Preston & Astbury but not recorded in their model, corresponds to microfibrils which are much less abundant than are those of the other two orientations both because the lamellae with this orientation are less frequent and because the microfibrils are more loosely packed in each lamella. The two ‘major’ directions ( A and B ) lie on an average at rather less than at right-angles to each other; the third direction ( x ) forms a bisector of this angle. The repeat from one lamella to the next can be . . . ABAB . . . or . . . AxB . . ., i.e. an interrupted two-lamella repeat, and not a three-lamella repeat as proposed by Steward & Muhlethaler. The structures of the walls of two whole vesicles have been worked out and give identical models. These are strictly equivalent to the model proposed by Preston & Astbury except that the third microfibril direction is present, making a rather steep right-hand spiral around the vesicle.
