Takotsubo syndrome (TTS) is usually associated with rapid and spontaneous recovery of left ventricular (LV) function. However, a proportion of patients may have persistent symptoms. This study aimed to determine the haemodynamic and LV contractile responses to exercise in these patients.

Musculoskeletal pain is common in the general population and constitutes a major public health problem. A large proportion of these conditions may be work related. The aim of this study was to explore the relative importance of physical, psychosocial and personal factors, in number of pain sites and in five specific pain sites, among women in common professions with a broad variety of occupational exposures.

Microscopic colitis (MC) is a chronic inflammation condition of the colon characterized by watery diarrhea and normal appearing mucosa. A 75-year-old female presented with one-year history of chronic diarrhea while taking cannabidiol (CBD) for pain. Colonoscopy with random colon biopsies revealed collagenous colitis. She started budesonide and stopped CBD. At six-week follow-up, her diarrhea improved, and the budesonide dose was decreased. She restarted CBD oil twice but had diarrhea both times. Her diarrhea resolved after taking budesonide and stopping CBD. We report a case of CBD-associated MC to make clinicians aware of this potential adverse effect in patients who chronically use CBD.

Musculoskeletal symptoms are common in patients with ulcerative colitis (UC), but no study has compared the prevalence of chronic pain to controls from a general population.

Intracranial hypotension can be a common sequela of a cerebrospinal fluid (CSF) leak. However, evidence of such a condition related to an injury in American football is currently lacking in the literature. While a positional or orthostatic headache is the most classic symptom of headaches due to intracranial hypotension, a variety of nonspecific symptoms such as neck pain, nausea, vomiting, photophobia, phonophobia, and visual changes can also be present. We present two cases where collegiate American football players developed protracted headaches after a concussive injury and were subsequently diagnosed with intracranial hypotension thought secondary to spinal CSF leaks.  Both players underwent multiple procedures of fluoroscopic-guided autologous blood patching, with improvement in their headaches. Recovery varied between the athletes. Case 1 achieved full resolution of his headaches and returned to full activity. Case 2 continued to have intermittent headaches after blood patching, but the positional nature had resolved and he was cleared for full participation in football and was closely followed during the remainder of his collegiate career. Both these cases emphasize the importance of including CSF leak as a cause of post-traumatic headache in an American football player.

A 62-year-old man with diabetes of 24 years' duration was referred by his physician to an ophthalmologist. The man presented with temporal headache and reduced vision in the right eye of 2 weeks' duration. His most recent HbA was 86 mmol/l (10%). The best corrected vision in the right eye was 1/60. The right eye showed episcleral congestion with mid-dilated pupil and neovascularization of the iris with nuclear sclerosis of the lens (Fig. 1a). Intraocular pressure was 34 mmHg and the fundus showed few mid-peripheral blot haemorrhages (Fig. 1b). Left eye vision was 6/9 with few blot haemorrhages in the posterior segment. Carotid Doppler revealed complete occlusion of the right internal carotid artery.

Objectives Nerve injury may lead to pain and sensory changes such as dysesthesia and paresthesia. Quantitative sensory testing (QST) is a psychophysical testing method used to quantify nerve damage and monitor its recovery. Duloxetine is used in the management of neuropathic pain conditions, but its effect on taste recovery has not been previously reported. Case representation A 65-year-old female, presented to the orofacial pain clinic, with a chief complaint of a burning sensation on the tongue, taste changes and a feeling of tightness beneath the tongue for five months. She reported that the complaints began subsequent to a complicated dental extraction during which she experienced trauma to the tongue. Patient was advised to take duloxetine 60 mg in divided doses three times daily. The assessment and monitoring of the recovery pattern were performed using QST. Electrical taste detection (mediated by chorda tympani) and electrical detection/tingling thresholds were performed at periodic intervals for up to a year following the nerve injury in the chorda tympani and lingual nerve territory. The patient reported complete recovery in taste sensation with duloxetine and this correlated with the QST results. QST documented at the end of one year revealed the electrical taste detection threshold and electrical detection threshold return to near normal values. Conclusions QST may be a useful diagnostic tool to assess and monitor lingual and chorda tympani nerve injuries. Duloxetine may aid in the recovery of the taste changes following lingual and chorda tympani nerve injury.

BACKGROUND Use of selective serotonin reuptake inhibitors (SSRIs) has been reported to be associated with the syndrome of inappropriate antidiuretic hormone (SIADH), although it is uncommon. Nonsteroidal anti-inflammatory drugs (NSAIDs), as a sole agent, are an even rarer cause of SIADH. Despite being documented in the literature, the understanding of the mechanism of both agents is limited. Here, we report a case of a patient taking both of these medications, a dangerous combination that led to the development of SIADH. CASE REPORT An 88-year-old woman with a history of asymptomatic chronic hyponatremia presented to our facility with symptomatic acute-on-chronic hyponatremia after she started using naproxen in addition to her daily citalopram. Her hyponatremia symptoms resolved after discontinuing these 2 offending agents, along with administration of fluid restriction and oral sodium supplements. CONCLUSIONS Naproxen is commonly prescribed and is often taken by elderly patients to control long-term or short-term pain. SSRIs, on the other hand, are a first-line treatment for depression and are usually prescribe by a psychiatrist. Hyponatremia is a rare medication adverse effect that should be kept in mind when treating these patients with either of these medications, and should especially be considered when combining them. Medication reconciliation should be done carefully by the provider to avoid adverse effects and drug interactions. When hyponatremia is encountered, options for future medication prescriptions include rechallenging with the same medication, switching to a different medication with the same mechanism of action, or using a medication from another class altogether. Monitoring of serum sodium level is warranted when titrating the offending agent.
