Idiopathic segmental anhidrosis in an older patient presenting with recurrent dizziness.

Dizziness is one of the most common complaints encountered in the outpatient clinic, which is difficult to diagnose, especially in older patients because of the multifactorial nature of the disease. Although not commonly recognised, anhidrosis can also cause dizziness.We report a case of a woman in her 70s who presented with long-term recurrent dizziness. She had a history of frequent hospitalisations for heatstroke. Physical examination revealed markedly less sweating in the left axilla and soles than in the right. Minol test revealed that most of the left side of her body, including the face, was anhidrotic. She was diagnosed with idiopathic segmental anhidrosis. We administered steroid pulse therapy without observing any significant effects.Although anhidrosis is a rare disorder, a careful interview and physical examination should be conducted to confirm a history of heatstroke and the absence of sweating to avoid missing the disease.

Aortic root dilation in acromegaly.

Previous studies have linked persistent elevations in growth hormone (GH) and insulin-like growth factor-1 (IGF-1) to cardiac abnormalities including aortic root dilation. Guidelines in the management of this dilation below the size recommended for surgery have not been well defined but follow-up and intervention when appropriate could be life-saving. We report the case of a man in his 60s who had been living with undiagnosed acromegaly for many years. His initial assessment through point-of-care ultrasound raised concerns about potential cardiac enlargement, prompting further investigation with a formal echocardiogram, which revealed a significant aortic root dilation measuring 4.5 cm. Subsequent blood tests confirmed elevated levels of IGF-1. Brain MRI showed a focal lesion in the pituitary gland, which was surgically resected, confirming the diagnosis of a GH-secreting pituitary adenoma. One year after surgery, a repeat CT angiogram of the chest demonstrated a stable size of the aortic root aneurysm.

Radiographical bony lesions after discontinuation of immunosuppressant therapy: bone involvement in sarcoidosis.

We describe a patient who had failed renal transplant after 13 years, eventually requiring a graft nephrectomy and discontinuation of immunosuppressive therapy, including antithymocyte globulin, tacrolimus and mycophenolate while on steroid avoidance protocol. Within a few months of complete discontinuation of the immunosuppressive medications, she developed lower back pain associated with numbness in her right anterolateral thigh. The radiological imaging demonstrated multiple bony lesions throughout her axial and appendicular skeleton with normal pulmonary findings. A computerised tomography-guided bone biopsy from the left iliac crest revealed fragments of bone with granulomatous inflammation, thus making the diagnosis of extrapulmonary sarcoidosis. Initiating treatment with prednisone resulted in near-complete resolution of symptoms. Long-term immunosuppressive therapy is administered to all renal transplant recipients to help prevent acute rejection and loss of renal allograft. This case highlights that immunosuppressants can conceal the presence of underlying conditions in transplant patients.

New tender, bleeding papule on the left ear.

Chondrodermatitis nodularis helicis (CNH) is a painful, inflammatory condition that impacts the skin of the ear. It is commonly associated with pressure on the pinna causing a nodule that may have erythema, bleeding and exudate. We present a case of a woman in her 60s with a history of basal cell carcinoma who presented with a new tender spot on the antihelix of her left ear. The tenderness of the new spot forced her to switch from holding her phone to her left ear to using her right ear. A shave biopsy confirmed CNH and ruled out non-melanoma skin cancer. Although most prior cases report association with sleeping on the side of the affected ear, this case was attributed to cell phone use. It is important to remember that non-traditional sources of pressure can also lead to CNH.

Pleisiomonas shigelloides bacteremia after catfish injury.

This case of Pleisimonas shigelloides bacteremia resulting after a catfish barb injury highlights an unusual presentation of a common condition that requires alternative therapy for successful treatment. An otherwise healthy male in his early 40s presented to the emergency department with sepsis and rapidly spreading cellulitis shortly after a catfish injury at a freshwater lake. His broad-spectrum antibiotics were narrowed to ciprofloxacin when P. shigelloides grew from his blood culture. The case presents a unique mode of bacteremia, as usually P. shigelloides bacteremia develops in immunocompromised hosts after bowel wall translocation. The venomous nature of catfish barbs also contributed to the severity and rapidity of his presentation secondary to the local tissue effects of envenomation. With proper antibiotics and supportive care, he made a full recovery.

Xiphodynia with limited decrease in the xiphoid process-sternal angle but recognised compression of the rectus abdominis.

A woman in her 70s presented with epigastric pain accompanied by radiating pain. Despite various examinations showing no abnormalities, tenderness was identified on palpation of the xiphoid process. The symptoms were alleviated with a local injection of lidocaine, leading to a diagnosis of xiphodynia. While previous cases have often reported a decrease in the xiphoid process-sternal angle, this case exhibited minimal reduction in the xiphoid process-sternal angle. Conversely, compression findings were observed in the soft tissues, including the rectus abdominis, anterior to the xiphoid process. This case report suggests that in the imaging diagnosis of xiphodynia, consideration of compression findings in the soft tissues anterior to the xiphoid process may also be valuable.

Pleural and pericardial effusions with fever and altered mental status: an atypical presentation of bartonellosis.

A male in his 60s presented to the emergency department (ED) with a 3-week history of fever and progressive confusion. Initial laboratory and radiographic workup was largely unremarkable except for moderate bilateral pleural effusions. The patient was admitted on broad-spectrum antibiotics and further workup for fever of unknown aetiology. The differential diagnosis was broadened to different zoonotic infections, and subsequent laboratory testing showed a markedly elevated Bartonella henselae IgG and Bartonella quintana IgG (1:4096 and 1:512, respectively) in addition to positive B. henselae IgM titre (>1:20). During hospitalisation, the patient became more hypoxic and was found to have enlarging pleural effusions as well as a new pericardial effusion. The patient was treated with intravenous then oral doxycycline 100 mg two times per day and oral rifampin 300 mg two times per day for 4 weeks with subsequent improvement in clinical status as well as both effusions. This case highlights a unique presentation of Bartonella and its rare manifestation of pleural and pericardial effusions.

Previously undiagnosed genetic disease in adult patient with hepatic masses and reported history of congenital hyperinsulinism.

Glycogen storage disease type 1A (GSD1A), also known as Von Gierke's disease, is a rare autosomal recessive disorder affecting glycogen metabolism in the liver. It most commonly presents in infancy with hypoglycaemia and failure to thrive, but cases have been reported as undiagnosed until adulthood. A woman in her early 20s with diabetes mellitus presented with right upper quadrant pain and was found to have several haemorrhagic hepatic adenomas. This patient had insulin-dependent diabetes since a pancreatectomy at age 9 months due to continued episodes of hypoglycaemia and suspected insulinoma. During the hospital stay, the hepatic adenomas were embolised, but significant lactic acidosis and hypoglycaemia continued. Further workup revealed a chronic lactic acid level, during several hospital stays, of above 5 mmol/L. After cytology of hepatic tissue ruled out hepatocellular carcinoma, the patient was discharged and recommended to follow-up for genetic testing, which confirmed the diagnosis of GSD1A.

Discrepant serum creatinine concentrations caused by paraprotein interference preceding diagnosis of monoclonal gammopathy of undetermined significance.

We report a man in his 70s who presented with discrepant serum creatinine concentrations in different hospitals at the same time. Further examinations of these discrepancies revealed turbidity of the serum sample and, thus, a reagent reaction and false hypercreatinine caused by paraprotein interference were suspected. Serum protein electrophoresis revealed a small amount of monoclonal γ globulin (2.9 g/L), which may have been involved in paraprotein interference. Monoclonal λ-type IgG was detected in the serum, resulting in a diagnosis of monoclonal gammopathy of undetermined significance. Previous studies indicated paraprotein interference in serum containing monoclonal IgM or a large amount of IgG (> 25 g/L). Although this case of paraprotein interference induced by a small amount of IgG is rare, a discrepancy in creatinine results may be an indicator leading to the diagnosis of plasma cell proliferative diseases.

Multiple cutaneous and uterine leiomyomatosis: Reed's syndrome.

Reed's syndrome (RS) is a rare autosomal-dominant disorder characterised by multiple cutaneous and uterine leiomyomas, with a strong tendency for renal cell carcinoma (RCC) development. A woman in her 50s, who had previously undergone total abdominal hysterectomy due to multiple uterine leiomyomas, presented with painful nodules on her trunk and right arm for the past 6 years. These nodules were confirmed as leiomyomas through histopathology. Diagnosis of RS was established through clinicopathological correlation and positive family history, particularly her mother's. Early-onset uterine leiomyomas in patients with a similar family history should raise suspicion for RS, necessitating vigilant long-term follow-up. RCC detection requires mandatory renal imaging. Screening family members and providing genetic counselling are crucial.

Mottled Raynaud's phenomenon and hand-arm vibration syndrome: followed up for 10 years.

Vibration white finger is a form of secondary Raynaud's phenomenon (RP) caused by the use of handheld vibrating tools. RP usually appears on the extremities of the fingers, and its borders are well recognised. No reports have been published on 'mottled' RP in continuous observation from the onset to the disappearance of RP. A man in his 60s who had been using vibrating tools such as jackhammers and tampers for 30 years presented with sensations of coldness, burning and numbness. Whole-body cold exposure was performed outdoors in winter, and RP was photographed continuously. 'Mottled' RP can be defined as triphasic colour changes: white, blue and red. The patient was taken off work, kept warm and medicated. His symptoms improved slightly after 10 years of follow-up, but the RP did not disappear. 'Mottled' RP is rare and refractory and should be recognised as a form of RP.

Acute intravascular haemolysis associated with scrub typhus.

Scrub typhus, a prevalent tropical infection, may sometimes manifest with unusual complications. Here, we present the case of a young man who was admitted to our facility with a fever for the past 3 days and passage of dark-coloured urine since that morning. On investigation, we identified intravascular haemolytic anaemia. Through meticulous examination, a black necrotic lesion (eschar) was discovered on his right buttock, a pathognomonic sign of scrub typhus infection. Treatment was initiated with oral doxycycline 100 mg two times a day. Subsequently, diagnosis of scrub typhus was confirmed through positive results from scrub typhus IgM via ELISA and PCR analysis from the eschar tissue. The patient responded well to oral doxycycline and his symptoms resolved within the next few days. This case highlights severe intravascular haemolysis associated with scrub typhus infection.

Identification of Francisella tularensis in ascites in the context of typhoidal tularaemia.

Tularaemia is a highly infectious, zoonotic disease caused by Francisella tularensis, which has become increasingly prevalent over the past decade. Depending on the route of infection, different clinical manifestations can be observed. We report a case of typhoidal tularaemia presenting as a febrile illness with gastrointestinal symptoms in a patient in her mid-80s. During the acute illness phase and in the context of alcohol-related liver cirrhosis, the patient developed progressive ascites. During paracentesis, spontaneous bacterial peritonitis was consistently reported. Blood culture revealed Gram-negative bacilli identified as F. tularensis upon microscopic examination. Immediate clinical improvement was observed after adaptation to a pathogen-specific antibiotic regime. Typhoidal tularaemia presents general, non-specific symptoms without the local manifestations seen in other forms of the disease, thus representing a diagnostic challenge. In the case of protracted fever and if the epidemiological context as well as possible exposure are compatible, tularaemia should be considered in the differential diagnosis.

Marathon pancreatitis: a case of acute pancreatitis caused by distance running.

Marathon running or other forms of strenuous exercise have been reported as a rare cause of acute pancreatitis. Theories as to the mechanism of acute pancreatitis include microvascular ischaemia due to dehydration or repetitive trauma to the pancreas. We report a case of a healthy woman in her 30s who developed abdominal pain, nausea and vomiting after a 32 km marathon training run. She was found to have elevated lipase and inflammation of the pancreatic tail with associated pericolic and pelvic free fluid on CT scan. Workup including abdominal ultrasound and magnetic resonance cholangiopancreatography (MRCP) did not reveal biliary or pancreatic duct pathology. She improved with conservative management. These findings support the hypothesis of exercise-induced pancreatitis from long-distance running.

Achromobacter pneumonia in a patient with advanced COPD, a diagnostic challenge.

Bacterial pneumonia causes significant morbidity and mortality especially in elderly and immunocompromised hosts. Achromobacter xylosoxidans denitrificans pneumonia is very rarely reported. However, the reported cases have been in patients who are either immunocompromised or have bronchiectasis. We hereby present a unique case of Achromobacter xylosoxidans denitrificans pneumonia in an immunocompetent patient with advanced chronic obstructive pulmonary disease (COPD). Our patient is a Caucasian male admitted with shortness of breath, fever and cough. Chest X-ray demonstrated right-sided infiltrates and he was treated with intravenous ceftriaxone and azithromycin. He was discharged home on oral amoxicillin-clavulanate 875-125 mg two times per day for a total of 7 days. Patient returned to emergency room after 5 weeks with persistent symptoms and chest X-ray revealed persistent right-sided infiltrate and sputum culture showed Achromobacter xylosoxidans denitrificans. The patient was started on oral levofloxacin 750 mg one time per day for 2 weeks with resolution of symptoms.

Iron overload in anaemia with underlying haemoglobin constant spring in an antenatal mother in primary care.

This is the case of a gravida 3 para 1 woman in her late 20s with underlying haemoglobin constant spring who visited a healthcare clinic for an antenatal check-up. Towards the end of her second trimester, she experienced lethargy. During her antenatal booking, she was diagnosed with mild asymptomatic anaemia, high serum ferritin, T saturation of 88% and abnormal liver function tests. She was referred to a hospital where an MRI scan revealed over 2 g of iron deposits in her liver, leading to a revised diagnosis of iron overload. Treatment included deferoxamine and expectant management throughout her antenatal period, and her delivery was uncomplicated. While iron deficiency anaemia is common in pregnancy, it is crucial not to overlook iron deposition and the distinction from acute fatty liver during pregnancy to prevent treatment delays.

Erythroderma with total scarring alopecia.

A woman in her 50s presented with total scarring ulcerated alopecia evolving for 10 years, and a recent budding tumour on the lower lip. Clinical examination revealed an associated exfoliated and infiltrated erythroderma with ulcerated cutaneous tumours of the legs, palmoplantar hyperkeratosis, hepatosplenomegaly and diffuse lymphadenopathies.Dermatoscopy of the scalp, leg tumours and infiltrated skin showed a typical yellowish background overlaid by arborescent vessels and whitish areas. Cutaneous biopsies of the same areas found sarcoidotic granulomas. Lip biopsy found an associated well-differentiated squamous cell carcinoma. Investigations confirmed the diagnosis of systemic sarcoidosis with an elevated converting enzyme level, mediastinal calcified lymphadenopathies in CT scan and deep localisations in positron emission tomography scan (thyroid, lymph nodes, mediastinum, liver, spleen and adrenal glands).The patient was treated with oral prednisone for sarcoidosis and intramuscular bleomycin followed by surgery and radiotherapy for squamous cell carcinoma. Sarcoidotic lesions healed, but a recurrence of her carcinoma led to death.

Pneumomediastinum as a postinfectious complication of COVID-19 in paediatric patient.

An adolescent boy presented to the clinic with upper chest pain, anterior neck pain and difficulty swallowing 3 weeks following a COVID-19 infection. The pain started a few days before while participating in football practice. He reported no significant trauma or specific incidence when the pain began. His vital signs were stable and within normal limits. There was tenderness to palpation in the upper sternal area and low anterior neck. A chest X-ray was performed and was originally read by the primary care physician as unremarkable. This was followed by the official radiology read, which identified a spontaneous pneumomediastinum. A follow-up CT was confirmatory. The physician recommended rest and minimal activity, and the symptoms gradually resolved in 1 week. A follow-up 1 week after the initial visit revealed complete resolution by radiograph. One week later, a final set of radiographs confirmed sustained resolution of free air in the mediastinum. He was able to gradually return to normal activity.

Presentation of multiple painful subcutaneous nodules: Dercum's disease, a rare variant of lipoma.

A woman in her 50s presented to her general practitioner (GP) with an 8-month history of multiple painful subcutaneous nodules of various sizes in her trunk and limbs. Her previous GP made the clinical diagnosis of lipoma when they presented as non-painful nodules 2 years ago. Initial ultrasound demonstrated multiple lipomata with the largest size in the left upper thighs displaying features of subtle internal vascularity, entirely contained within the subcutaneous layer. MRI scan of thigh lesions showed multiple angiolipomas consistent with the entity of Dercum's disease. Subsequent biopsy histology confirmed the image diagnosis of angiolipoma. She was referred to a musculoskeletal oncological surgeon for evaluation and reassurance regarding optimising medical management of her associated obesity. Her angiolipoma and obesity are well managed by her GP. This case highlights the diagnostic workup of a rare variant of lipoma, Dercum's disease. The differential diagnosis of multiple painful lipomas was reviewed and discussed, consequently leading to the discussion of managing the associated obesity in this case.

Gram-negative bacillary meningitis in an immunocompetent adult.

Escherichia coli is a rare cause of community-acquired meningitis comprising about 1% of adult cases. However, it is a common pathogen in neonatal meningitis and in nosocomial setting (especially after penetrating craniocerebral injury or subsequent to neurosurgical procedures). We report a middle-aged woman, who was admitted with features of acute meningitis and subsequent investigations revealed E. coli growth in cerebrospinal fluid culture. The case is distinctive as no additional predisposing risk factors associated with gram-negative bacillary meningitis (traumatic brain injury, neurosurgical procedures, malignancy, immunosuppressive therapy, HIV infection, chronic alcoholism and diabetes) were present. She was treated with intravenous antibiotics as per sensitivity reports and discharged in clinically stable condition, without any residual neurological deficit.
